DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(53) Embodiments of the present disclosure are described in detail hereinafter, and the present disclosure can be implemented by various manners limited and covered by the claims.

(54) According to a first specific implementation manner of the present disclosure, the present disclosure provides a single-row multilayer storage warehouse system with vertical avoidance. As shown in FIGS. 1-2, the single-row multilayer storage warehouse system comprises a plurality of storage layers 1, a plurality of storage shelf lifting apparatus 2, shafts 3, supporting mechanisms 4, supporting mechanism lifting apparatus 5a, a plurality of self-delivering trolleys 6 and two supporting mechanism horizontal movement layers 7.

(55) The storage layers 1 include 2-6 layers, wherein the seventh layer is vacated for providing a space for upward movement of goods 8 on the sixth layer; more storage layers 1 can be arranged according to actual requirements; and only the upper layer of the storage layer 1 on the uppermost layer needs to be vacated. The first layer and the eighth layer are the supporting mechanism horizontal movement layers 7 for horizontal movement of the supporting mechanisms 4. The two shafts 3 are arranged at both ends of the storage warehouse system, and the supporting mechanism lifting apparatus 5a is configured to enable the supporting mechanisms 4 to move up and down in the shafts 3.

(56) As shown in FIGS. 1, 2 and 4-7, each storage layer 1 is provided with five storage shelf groups arranged side by side; each storage shelf group comprises two storage shelves 11 arranged symmetrically; and each storage layer 1 can be provided with seven/eight/even more storage shelf groups according to actual requirements. Each storage shelf group is in a cuboid structure; each storage shelf group corresponds to four guide posts 14; and the four guide posts 14 are respectively and vertically fixed on four vertical sides of the storage shelf group. The length of each guide post 14 is equal to the height of each storage layer 1, and the storage shelf groups are directly stacked one by one from bottom to top, so that each storage shelf lifting apparatus 2 can be configured to directly control the storage shelf groups in the same vertical direction. A dust blocking plate 112 (which is in non-rigid connection or is not arranged) is arranged at the upper part of each storage shelf group, and a first supporting component 111 for storing the goods 8 is arranged at the lower part of the storage shelf group. First rails 12 are fixed at the top of each of the storage shelves 11, except the storage shelves 11 on the uppermost layer, and the first rail 12 may be not arranged on the storage shelves 11 on the uppermost layer. A fourth fixed rail 13 is fixed under each of the storage shelves 11 on the lowermost layer. On the storage layers 1, except the storage layer 1 on the lowermost layer, the self-delivering trolleys 6 are capable of running on the first rails 12 on the same layer through third supplementary rails 28 on first joining beams 27 and fifth supplementary rails 30 on second joining beams 29. On the storage layer 1 on the lowermost layer, the self-delivering trolleys 6 are capable of running on the fourth fixed rails 13 through third supplementary rails 28 on first joining beams 27. Second calibrating and positioning devices are arranged on the first rails 12 and the fourth fixed rails 13, and the second calibrating and positioning devices are second positioning holes.

(57) As shown in FIGS. 2-6, a plurality of first joining beams 27 arranged horizontally are arranged between two first steel upright columns 21 that are near each shaft 3; the third supplementary rails 28 are arranged on the first joining beams 27; the third supplementary rails 28 are connected with guide rails 41 and the first rails 12 or the fourth fixed rails 13; a plurality of second joining beams 29 arranged horizontally are arranged between every two of other first steel upright columns 21; the fifth supplementary rails 30 are arranged on the second joining beams 29; and each fifth supplementary rail 30 is connected with every two adjacent first rails 12.

(58) As shown in FIGS. 2, 4 and 9, each self-delivering trolley 6 comprises a rectangular main frame 61, a rechargeable battery pack, first running wheels 62 located on both sides of the main frame 61, a second supporting component 63 arranged above the main frame 61, a goods lifting mechanism (which is internally arranged and is not shown in the figures) and third calibrating and positioning devices 65. The first running wheels 62 are used for enabling the self-delivering trolley 6 to move on the first rails 12, the fourth fixed rails 13, the third supplementary rails 28, the fifth supplementary rails 30 and the guide rails 41 on the supporting mechanisms 4. The goods 8 are placed on the second supporting component 63, and the goods lifting mechanism is used for enabling the second supporting component 63 and the goods 8 to move up and down, so that the second supporting component 63 is higher or lower than the first supporting component 111. The goods lifting mechanism is capable of lifting the second supporting component 63 to the highest point above the first supporting component 111, and of lowering the second supporting component 63 to a lowest point below the first supporting component 111. When the self-delivering trolley 6 is located right under one storage shelf group, the position of the second supporting component 63 is staggered with the horizontal position of the first supporting component 111.

(59) In FIG. 4, the first supporting component 111 is in a comb shape, and the positions corresponding to the first supporting component 111 on each second supporting component 63 are vacated to form comb shapes. As shown in FIGS. 9-10, each third calibrating and positioning device 65 is arranged in the middle of each of the long edges of the main frame 61; the third calibrating and positioning device 65 comprises a second push rod 651 arranged vertically and a second telescopic tongue 652 fixed at the lower end of the second push rod; and the lower end of the second telescopic tongue 652 is in a cone shape (which has a function of calibration) and can be inserted into the second positioning hole.

(60) As shown in FIGS. 1 and 4, when each self-delivering trolley 6 moves on the first rails 12 or the fourth fixed rails 13 on the same layer through the third supplementary rails 28 on the first joining beams 27 and the fifth supplementary rails 30 on the second joining beams 29, if the goods 8 are not in front of the self-delivering trolley 6, two situations are described as follows: when the self-delivering trolley 6 is empty, the goods lifting mechanism descends to the lowest point, and the second supporting component 63 is lower than the first supporting component 111, so that the self-delivering trolley 6 can directly run between the first rail 12 on the storage shelves 11 on the lower layer and the bottom of the first supporting component 111 of the storage shelves 11 on the layer; and when the self-delivering trolley 6 is loaded with the goods 8, the goods lifting mechanism ascends to the highest point, and the second supporting component 63 is higher than the first supporting component 111, so that the self-delivering trolley 6 is capable of running through the storage shelves 11, the goods 8 are not blocked by the first supporting component 111, and a safety passing distance is left between the top of the goods and the bottom of the first supporting component 111 of the storage shelves 11 on the upper layer. When the self-delivering trolley 6 moves on the first rail 12 or the fixed rails 13 on the same layer through the third supplementary rails 28 on the first joining beams 27 and the fifth supplementary rails 30 on the second joining beams 29, if the goods 8 are in front of the self-delivering trolley 6, the storage shelf group 11 loaded with the goods 8 and all groups of storage shelves 11 right above the storage shelf group 11 are moved upwards by the storage shelf lifting apparatus 2. Each storage shelf lifting apparatus 2 is used for driving all storage shelves 11 in the same vertical direction to move up and down.

The guide posts 14 are in a hollow structure, and each lifting rod 23 vertically penetrates through the interior of all the guide posts 14 on the same first steel upright column 21, so as to string the guide posts 14. A rigid supporting seat is arranged at the bottom of each first steel upright column 21, and the rigid supporting seats are used for supporting the guide post 14 of the storage shelves on the lowermost layer.

The telescopic sleeve 2314 is in a hollow rectangular tubular structure, the connecting position of the two hook arms 2311 is arranged at the upper part of the telescopic sleeve 2314. The telescopic sleeve 2314 can move up and down along with the third push rod 2315, and the two hook arms 2311 are sleeved in or released out of the telescopic sleeve 2314. When the two hook arms 2311 are released out of the telescopic sleeve 2314, the two hook arms 2311 are opened outwards and are connected with the lifting bayonets 141 in a clamping manner, and at the moment, the lifting rods 23 move upwards to drive the guide post 14 and the storage shelves 11 connected with the guide post 14 to move upwards; and when the two hook arms 2311 are sleeved in the telescopic sleeve 2314, the two hook arms 2311 draw back inwards, the lifting rods 23 move upwards at the moment, and the guide post 14 and the storage shelves 11 connected with the guide post 14 do not move upwards along with the lifting rods 23. When the guide post 14 move up and down, the roller bearings 142 are in touch with the guide grooves 211 of the first steel upright columns 21 and roll in the guide grooves 211, so as to be favorable for reducing friction.

(65) As shown in FIGS. 12-13 and 15, each storage shelf lifting apparatus 2 is provided with four lifting rods 23, and the synchronization mechanism 25 is used for enabling the four lifting rods 23 to go up and down synchronously. The synchronization mechanism 25 comprises four second synchronous racks 251 that are vertically fixed at the upper parts of the lifting rods 23, two longitudinal synchronous shafts 252, four second synchronous gears 253, two third synchronous gears 254, a transverse synchronous shaft 255 and two fourth synchronous gears 256.

The non-return tongue 2621 is capable of rotating along the axial direction of the torsional spring 2623, so that the non-return tongue 2621 is clamped with or separated from the fall prevention non-return rack 261. In a normal state, the DC coil body 2622 remains charged and is used for pulling the non-return tongue 2621 away from the fall prevention non-return rack 261; and when a hydraulic system is decompressed (such as the crack of an oil pipe and the like), a pressure sensor of the hydraulic system is configured to send a signal, the electricity of the DC coil body 2622 is cut off by a control system in time, and the non-return tongue 2621 is rotated under the torsion of the torsional spring 2623 and is clamped with the fall prevention non-return rack 261, so as to avoid falling down of the lifting rod 23.

(68) As shown in FIGS. 1-2, 16-17 and 20-22, the supporting mechanism 4 comprises a rectangular frame body; and the guide rails 41 which are parallel to the first rails 12 are arranged at the top of the frame body, so that when the supporting mechanism 4 stays on each storage layer 1, the guide rails 41 are connected with all the first rails 12 or all the fourth fixed rails 13 on the layer to form a continuous rail through the third supplementary rails 28 and the fifth supplementary rails 30, and the self-delivering trolley 6 is capable of running from the first rails 12 or the fourth fixed rails 13 on the same layer onto the guide rails 41 or run from the guide rails 41 onto the first rails 12 or the fourth fixed rails 13 on the same layer. A plurality of running wheels 43, first calibrating and positioning devices 44 and fourth calibrating and positioning devices 45 are arranged on both sides of the supporting mechanism 4. The running wheels 43 are used for moving on the supporting mechanism horizontal movement layer 7. The first calibrating and positioning devices are first positioning holes, are arranged on the guide rails 41 and can be inserted by the second telescopic tongues on the self-delivering trolley 6. The fourth calibrating and positioning devices 45 are arranged in the middle of the long edges of the frame body; the structure of the fourth calibrating and positioning device 45 is similar to that of the third calibrating and positioning device 65; the fourth calibrating and positioning device 45 comprises a fifth push rod arranged vertically and a third telescopic tongue fixed at the lower end of the fifth push rod; and the lower end of the third telescopic tongue is in a cone shape. The supporting mechanism 4 also comprises a rechargeable battery pack which is used for driving the supporting mechanism 4 to move on the supporting mechanism horizontal movement layer 7.

(69) When the supporting mechanism 4 stays on each storage layer 1, in order that the joining of the guide rails 41 and the first rails 12 or the fourth fixed rails 13 is more precise, as shown in FIGS. 16 and 18-22, forcible indirect precise leveling sub-systems are adopted. Each forcible indirect precise leveling sub-system comprises a forcible leveling device 42, a forcible leveling jacket 425, an adjusting device 426 and a forcible leveling female seat 31. Each forcible leveling device 42 is arranged on each of the side surfaces of the supporting mechanism 4; and each forcible leveling device 42 comprises two first telescopic tongues 421, two first synchronous racks 422, a first synchronous gear 423 and a first push rod 424 which is telescopic in the horizontal direction. The first telescopic tongues 421 are fixed at both ends of the first push rod 424 and are capable of stretching out and drawing back along with the first push rod 424; one end of each first synchronous rack 422 is fixedly connected with the first telescopic tongue 421; and the other ends of the first synchronous racks 422 are meshed with the first synchronous gear 423. The forcible leveling jackets 425 are rigidly connected with the supporting mechanism 4; the forcible leveling device 42 is arranged in the forcible leveling jackets 425; the adjusting devices 426 are arranged at the bottom of the forcible leveling jackets 425; and each adjusting device 426 comprises a supporting spring and an adjusting bolt and is used for enabling the forcible leveling device 42 to suspend at the central positions in the vertical direction of the forcible leveling jackets 425. Meanwhile, the forcible leveling female seats 31 are arranged on each layer of the shafts 3, and each forcible leveling female seat 31 is internally provided with a position sensor corresponding to the first telescopic tongues 421. As shown in FIG. 19, a trumpet opening for receiving the first telescopic tongues 421 is formed in the forcible leveling female seat 31. As shown in FIG. 20, when the supporting mechanism 4 moves up and down, the first telescopic tongues 421 draw back; and when the supporting mechanism 4 needs to stay on a storage layer 1, as shown in FIG. 21, the first telescopic tongues 421 are inserted into the forcible leveling female seats 31, so as to realize precise positioning. As shown in FIG. 3 and FIG. 6, the guide rails 41 are precisely joined with the first rails 12 or the fourth rails 13 through the third supplementary rails 28 on the first joining beams 27 and the fifth supplementary rails 30 on the second joining beams 29.

(70) Specifically:

(71) The forcible leveling jackets 425 are rigidly connected with the frame body of the supporting mechanism 4; the forcible leveling devices 42 are placed in the forcible leveling jackets 425 and are constrained by the forcible leveling jackets 425; the forcible leveling devices 42 (which are composed of the first telescopic tongues 421, the first synchronous racks 422 and the first electric push rods 424 (which are provided with telescopic initial point position sensors), wherein both ends of each first telescopic tongue 421 are telescopic synchronously) can only move up and down in the forcible leveling jackets 425; and the adjusting devices 426 (which are mainly composed of the supporting springs and the adjusting bolts) are used for enabling the forcible leveling devices 42 to suspend approximately (precision is not needed) at the center in the vertical height of the forcible leveling jackets 425. After the supporting mechanism 4 is configured to receive parking instructions of the position sensors and is parked (at the moment, the central height of the first telescopic tongues 421 of the forcible leveling device 42 is flush with the central height of the forcible leveling female seats 31 in the design, and an allowable error exists actually), the first telescopic tongues 421 of the forcible leveling devices 42 stretch out and are inserted into the forcible leveling female seats 31 on second steel upright columns 36 (the internally arranged position sensors are configured to send confirmation feedback signals to the system when the first telescopic tongues 421 are inserted in place). As the opening of the forcible leveling female seat 31 is in a trumpet shape, a certain error range is allowed, and the forcible leveling devices 42 are in a suspension state, so that the allowable error range is larger after addition of two terms, and the allowable error range is much larger than the parking position error caused by different loading weights of the supporting mechanism 4 (the supporting mechanism 4 is empty sometimes, is loaded with the self-delivering trolley 6 sometimes and is loaded with the self-delivering trolley 6 and the goods 8 sometimes). Therefore, a hard interference phenomenon does not occur. After the supporting mechanism 4 is configured to receive confirmation signals of insertion in place, which are sent by the position sensors in the forcible leveling female seats 31, a brake is released, so that the supporting mechanism 4 falls on the forcible leveling devices 42 that are arranged front and back; and at the moment, the guide rails 41 on the supporting mechanism 4 are flush with the third supplementary rails 28 on the first joining beam 27 between the first steel upright columns 21 and the first rails 12 or the fourth fixed rails 13 (the fifth supplementary rails 30 on the second joining beams 29 are flush with the first rails 12), so as to form a smooth continuous rail (as shown in FIG. 3) and realize precise leveling. The supporting mechanism 4 needs to move upwards a little distance when the supporting mechanism 4 is transformed from a leveling state into an upward or downward movement state, so that after the forcible leveling devices 42 are recovered to suspend, the first telescopic tongues 421 draw back in place, and the confirmation signals are sent to the system, the supporting mechanism 4 can move upwards or downwards.

(72) The supporting mechanism 4 moves up and down between every two adjacent layers by the supporting mechanism lifting apparatus 5a. As shown in FIGS. 2, 3, 5 and 20-22, the supporting mechanism lifting apparatus 5a comprises a plurality of vertical racks 5a-1, a plurality of vertical guide rails 5a-2, a plurality of trolley conductors 5a-3, a plurality of movement gears 5a-4 meshed with the vertical racks 5a-1, first motor 5a-5, a plurality of guide shoes 5a-6, a plurality of electricity collection clips 5a-7, a plurality of fourth push rods 5a-8 which are telescopic and are arranged horizontally and a plurality of third synchronous racks 5a-9. Each shaft 3 comprises four second steel upright columns 36 for supporting the supporting mechanisms 4 to move up and down, and the second steel upright columns 36 are vertically arranged at four corners of the shaft 3. The vertical racks 5a-1, the vertical guide rails 5a-2 and the trolley conductors 5a-3 are all vertically fixed on the second steel upright columns 36 of the shaft 3. The movement gears 5a-4, the first motor 5a-5, the guide shoes 5a-6, the electricity collection clips 5a-7, the fourth push rods 5a-8 and the third synchronous racks 5a-9 are all arranged on the supporting mechanism 4. The first motor 5a-5 is used for providing power of rotation for the movement gears 5a-4 and driving the supporting mechanism 4 to move up and down. The guide shoes 5a-6 are fixed at both ends of each fourth push rod 5a-8; and the guide shoes 5a-6 are matched with the vertical guide rails 5a-2 when the guide shoes 5a-6 stretch out along with the fourth push rod 5a-8, so that the supporting mechanism 4 can move up and down along the vertical guide rails 5a-2. The electricity collection clips 5a-7 are fixed at both ends of the fourth push rod 5a-8; and the electricity collection clips 5a-7 are in touch with the trolley conductors 5a-3 to obtain electricity when the electricity collection clips 5a-7 stretch out along with the fourth push rod 5a-8. The third synchronous racks 5a-9 are used for enabling the guide shoes 5a-6 and the electricity collection clips 5a-7 to be telescopic synchronously. As shown in FIG. 23, the electricity collection clip 5a-7 comprises two electricity collection clip plates 5a-71, an insulated base 5a-72 arranged on the outer side of the electricity collection clip plates 5a-71, a closed spring 5a-73, two fourth pins 5a-74 and wiring lugs 5a-75 arranged at the upper parts of the fourth pins 5a-74. The two fourth pins 5a-74 are respectively fixed on the insulated base 5a-72 and are connected with the electricity collection clip plates 5a-71, so that the electricity collection clip plates 5a-71 is capable of rotating by taking the fourth pins 5a-74 as shafts. The closed spring 5a-73 is connected with the insulated base 5a-72 and the electricity collection clip plates 5a-71. When the electricity collection clips 5a-7 are used for obtaining electricity, the trolley conductors 5a-3 are located between the two electricity collection clip plates 5a-71.

(73) As shown in FIGS. 1-3 and 20-22, when the supporting mechanism 4 is driven to move to the supporting mechanism horizontal movement layer 7 on the lowermost layer by the supporting mechanism lifting apparatus 5a, the fourth push rods 5a-8 draw back, so that the guide shoes 5a-6 are separated from the vertical guide rails 5a-2, the electricity collection clips 5a-7 are separated from the trolley conductors 5a-3, and the supporting mechanism 4 can move horizontally on the supporting mechanism horizontal movement layer 7. The supporting mechanism horizontal movement layer 7 is provided with third rails 73 for horizontal movement of the supporting mechanism 4, and the third rails 73 extend to the shaft 3, so that the supporting mechanism 4 can move on the third rails 73. Fifth calibrating and positioning devices are arranged on the third rails 73 on the lowermost layer of the shaft 3; and the fifth calibrating and positioning devices are third positioning holes and correspond to the fourth calibrating and positioning devices 45 on the supporting mechanism 4. Each fifth calibrating and positioning device comprises the third positioning hole, into which the third telescopic tongue can be inserted. As shown in FIG. 2 and FIG. 24, horizontal gear guide plates 72 are arranged on the supporting mechanism horizontal movement layer 7 on the lowermost layer; extension movement gear guide plates 35 are arranged on the shaft 3; the gear guide plates 72 and the extension movement gear guide plates 35 are both have the same tooth shape as that of the vertical racks 5a-1 and are in alignment with the vertical racks 5a-1, so that the movement gears 5a-4 can horizontally slide on the gear guide plates 72 and the extension movement gear guide plates 35, and the movement gears 5a-4 keep meshing with the corresponding vertical racks 5a-1 when the supporting mechanism 4 horizontally moves from the shaft 3 to the other shaft 3.

(74) When the supporting mechanism 4 is driven to be about to move to the supporting mechanism horizontal movement layer 7 on the uppermost layer by the supporting mechanism lifting apparatus 5a, the supporting mechanism 4 is about to horizontally move on the supporting mechanism horizontal movement layer 7. As shown in FIG. 2 and FIG. 25, the supporting mechanism horizontal movement layer 7 is provided with second rails 71 for horizontal movement of the supporting mechanism, and the shaft 3 is provided with first supplementary rails 32, fifth push rods 33 which are arranged horizontally and are telescopic and overhaul position supplementary rail devices 34 on the layer. The fifth push rods 33 are vertically connected with the first supplementary rails 32, and the first supplementary rails 32 are parallel to the second rails 71 on the uppermost layer and can be connected with or separated from the second rails 71 on the uppermost layer along with the horizontal movement of the fifth push rods 33. When the first supplementary rails 32 are connected with the second rails 71 on the uppermost layer, the supporting mechanism 4 is capable of running from the first supplementary rails 32 onto the second rails 71 or run from the second rails 71 onto the first supplementary rails 32. Each first supplementary rail 32 is provided with a sixth calibrating and positioning device, and the sixth calibrating and positioning devices are fourth positioning holes and correspond to the fourth calibrating and positioning devices 45 on the supporting mechanism 4. As shown in FIG. 2 and FIG. 6, the overhaul position supplementary rail device 34 is higher than the first supplementary rail 32, and the height difference of the overhaul position supplementary rail device 34 and the first supplementary rail 32 is greater than the height of the supporting mechanism 4, so that the overhaul position supplementary rail device 34 does not affect the cycle running of the supporting mechanism 4. The overhaul position supplementary rail device 34 comprises sixth supplementary rails 341 and sixth push rods 342 which are arranged horizontally and are telescopic; the sixth push rod 342 is vertically connected with the sixth supplementary rail 341; and the sixth supplementary rails 341 are parallel to the first supplementary rails 32 and can be separated to both sides of the shaft 3 or draw back along with the horizontal movement of the sixth push rods 342. A plurality of notches are formed in the sixth supplementary rails 341, so that the supporting mechanism 4 is fixed on the sixth supplementary rails 341. When the supporting mechanism 4 breaks down and needs to be maintained, the sixth supplementary rails 341 stretch to both sides of the shaft 3, and the supporting mechanism 4 ascends in the shaft 3 and is higher than the overhaul position supplementary rail devices 34. The sixth supplementary rails 341 of the overhaul position supplementary rail devices 34 are driven to move into the shaft 3 to the position under the supporting mechanism 4 by the sixth push rods 342, the supporting mechanism 4 moves downwards onto the sixth supplementary rails 341, and the second running wheels 43 of the supporting mechanism 4 are clamped with the notches in the sixth supplementary rails 341, so that the supporting mechanism 4 is fixed on the sixth supplementary rails for overhauling. Horizontal gear guide plates 72 are arranged on the supporting mechanism horizontal movement layer 7 on the uppermost layer, extension movement gear guide plates 35 are arranged on the shaft 3, and the gear guide plates 72 and the extension movement gear guide plates 35 are both have the same tooth shape as that of the vertical racks 5a-1 and are in alignment with the vertical racks 5a-1, so that the movement gears 5a-4 can horizontally slide on the gear guide plates 72 and the extension movement gear guide plates 35.

(75) In order to improve the storage and pick-up efficiency of the goods 8, the supporting mechanism 4 in the shaft 3 at one end only moves upwards; the supporting mechanism 4 in the shaft 3 at the other end only moves downwards; the supporting mechanism 4 in the supporting mechanism horizontal movement layer 7 on the uppermost layer only moves horizontally to one direction; the supporting mechanism 4 in the supporting mechanism horizontal movement layer 7 on the lowermost layer only moves to the other direction; and therefore, a circular path is formed, so that the supporting mechanism 4 can do unidirectional movement clockwise or anticlockwise.

(76) The goods 8 in FIG. 1 enter a warehouse from the left bottom corner and move out of the warehouse from the right bottom corner; the circular path of the supporting mechanism 4 is that: along the anticlockwise direction, the supporting mechanisms 4 moves from the supporting mechanism horizontal movement layer 7 on the lowermost layer to the shaft 3 on the right side, then moves upwards from the shaft 3 on the right side to the supporting mechanism horizontal movement layer 7 on the uppermost layer, moves horizontally to the uppermost layer of the shaft 3 on the left side and finally moves downwards from the shaft 3 on the left side to the lowermost layer.

(77) The principle of storing the goods is described as follows:

(78) (1) The goods 8 are transported to the position above the supporting mechanism 4 loaded with the self-delivering trolley 6; and at the moment, the goods 8 are located on the lowermost layer of the shaft 3 on the left side in FIG. 1 and right above the second supporting component 63, and the guide shoes 5a-6 and the electricity collection clips 5a-7 draw back.

(79) (2) The supporting mechanism 4 moves horizontally forwards (the supporting mechanism 4 moves rightwards in FIG. 1) to transport the goods 8 to the lowermost layer of the shaft 3 on the right side.

(80) (3) The fourth calibrating and positioning devices 45 of the supporting mechanism 4 and the fifth calibrating and positioning devices on the third rails 73 are matched for calibrating and positioning (so that the supporting mechanism 4 is located at the center of the lowermost layer of the shaft 3).

(81) (4) The fourth push rods 5a-8 extend, the guide shoes 5a-6 stretch out onto the vertical guide rails 5a-2, and the electricity collection clips 5a-7 stretch out to be in touch with the trolley conductors 5a-3, so as to obtain electricity for the first motor 5a-5; and the first motor 5a-5 is configured to obtain electricity, and after instructions of the control signals are received, the first motor 5a-5 is configured to drive the movement gears 5a-4 to rotate to be meshed with the vertical racks 5a-1, so as to drive the supporting mechanism 4 to move upwards.

(82) (5) The supporting mechanism 4 runs to the designated storage layer 1, the movement gears 5a-4 stop rotating, and the first telescopic tongues 421 stretch out and are inserted into the trumpet openings of the forcible leveling female seats 31, so that the supporting mechanism 4 is precisely positioned, and the guide rails 41 are precisely connected with the first rail 12.

(83) (6) The third calibrating and positioning devices 65 of the self-delivering trolley 6 and the second calibrating and positioning devices on the first rail 12 are matched for calibrating and positioning, the second supporting component 63 ascends to be higher than the first supporting component 111, and the self-delivering trolley 6 moves leftwards to the designated storage shelves 11; and if other goods 8 are in front of the self-delivering trolley 6, the lifting hooks corresponding to the storage shelves, on which the goods 8 are located, are opened, other lifting hooks draw back, and the lifting rods 23 move upwards and drive the goods 8 and all storage shelves 11 on the upper layers of the goods 8 to move upwards. At the same time, the supporting mechanism 4 moves upwards, passes through the supporting mechanism horizontal movement layer 7 on the uppermost layer and moves into the shaft 3 on the left side.

(84) (7) The self-delivering trolley 6 reaches the designated storage shelves 11, the second supporting component 63 descends to be lower than the first supporting component 111, and the goods 8 are supported by the first supporting component 111, so as to complete the storage of the goods 8.

(85) (8) The self-delivering trolley 6 continues to move leftwards onto the supporting mechanism 4 in the shaft 3 on the left side and waits for the storage and pick-up of the next goods 8.

(86) The principle of picking up the goods is described as follows:

(87) (1) The supporting mechanism 4 is used for transporting the empty self-delivering trolley 6 to the designated storage layer 1 of the shaft 3 on the right side.

(88) (2) The self-delivering trolley 6 runs from right to left to the position right under the designated storage shelves 11, and at the moment, the second supporting component of the self-delivering trolley 6 is lower than the first supporting component 111.

(89) (3) The third calibrating and positioning devices 65 of the self-delivering trolley 6 and the first calibrating and positioning devices on the first rail 12 are matched for calibrating and positioning, the second supporting component 63 ascends to be higher than the first supporting component 111, and the goods 8 are supported by the second supporting component 63.

(90) (4) The second supporting component 63 keeps the height unchanged, and the self-delivering trolley 6 runs leftwards; and if other goods 8 are in front of the self-delivering trolley 6, the lifting hooks corresponding to the storage shelves 11 of the goods 8 stretch out, other lifting hooks draw back, and the lifting rods 23 move upwards and drive the goods 8 and all storage shelves 11 on the upper layers of the goods 8 to move upwards.

(91) (5) In the shaft 3 on the left side, the supporting mechanism 4 moves downwards to the designated storage layer 1, the movement gears 5a-4 stop rotating, and the first telescopic tongues 421 stretch out and are inserted into the trumpet openings of the forcible leveling female seats 31, so that the supporting mechanism 4 is precisely positioned, and the guide rails 41 are precisely connected with the first rail 12; and the self-delivering trolley 6 runs onto the guide rails 41 of the supporting mechanism 4.

(92) (6) The third calibrating and positioning devices 65 of the self-delivering trolley 6 and the first calibrating and positioning devices 44 of the supporting mechanism are matched for calibrating and positioning, and the second supporting component 63 descends.

(93) (7) The supporting mechanism 4 moves upwards a little distance and then stops, so that the forcible leveling devices 42 are recovered to suspend, then the first telescopic tongues 421 draw back in place, and confirmation signals are sent to the control system; next, the supporting mechanism 4 moves downwards to the lowermost layer of the shaft 3 on the left side; the fourth push rods 5a-8 draw back; the guide shoes 5a-6 and the electricity collection clips 5a-7 draw back; and the supporting mechanism 4 moves rightwards to the lowermost layer of the shaft 3 on the right side, and the goods 8 are unloaded.

(94) The principle of cycle running of the supporting mechanism 4 is described as follows:

(95) (1) The initial position of the supporting mechanism 4 is the lowermost layer of the shaft 3 on the left side; at the moment, the guide shoes 5a-6 and the electricity collection clips 5a-7 draw back, and the supporting mechanism 4 moves horizontally rightwards to the lowermost layer of the shaft 3 on the right side; and the movement gears 5a-4 of the supporting mechanism 4 keep meshing with the gear guide plates 72 in the whole process.

(96) (2) The fourth calibrating and positioning devices 45 and the fifth calibrating and positioning devices are matched for calibrating and positioning, the guide shoes 5a-6 stretch out to the vertical guide rails 5a-2, and the electricity collection clips 5a-7 stretch out to the trolley conductors 5a-3.

(97) (3) The movement gears 5a-4 are driven to move upwards by the first motor 5a-5; and when the supporting mechanism 4 needs to stay on a storage layer 1 for storing the goods 8, the first motor 5a-5 brakes and stops rotating, and the first telescopic tongues 421 stretch into the trumpet openings of the forcible leveling female seats 31 on the layer, so as to realize forcible indirect precise positioning of the supporting mechanism 4 on the layer.

(98) (4) After the self-delivering trolley 6 and the goods 8 leave the supporting mechanism 4, the supporting mechanism 4 ascends a little distance and then stops, so that the forcible leveling devices 42 are recovered to suspend, the first telescopic tongues 421 draw back in place, and the confirmation signals are sent to the control system; and next, the movement gears 5a-4 are driven to move upwards to be higher than the first supplementary rails 32 by the first motor 5a-5, and at the moment, the first supplementary rails 32 are driven to horizontally open to both sides of the supporting mechanism 4 by the fifth push rods 33, so that the supporting mechanism 4 can move upwards.

(99) (5) After the supporting mechanism moves upwards to be higher than the supporting mechanism horizontal movement layer 7 on the uppermost layer, the first supplementary rails 32 are pushed to move horizontally inwards by the fifth push rods 33 until the first supplementary rails 32 are connected with the second rails 71 of the supporting mechanism horizontal movement layer 7 on the uppermost layer.

(100) (6) The brake is released by the first motor 5a-5, so that the movement gears 5a-4 move downwards until the second running wheels 43 of the supporting mechanism 4 are in touch with the first supplementary rails 32; and the supporting mechanism 4 is supported by the first supplementary rails 32.

(101) (7) The guide shoes 5a-6 and the electricity collection clips 5a-7 draw back, and the supporting mechanism 4 moves leftwards along the second rails 71 to the uppermost layer of the shaft 3 on the left side; and the movement gears 5a-4 of the supporting mechanism 4 keep meshing with the gear guide plates 72 in the whole process, and at the moment, the first supplementary rails 32 on the uppermost layer of the shaft 3 on the left side are connected with the second rails 71.

(102) (8) The fourth calibrating and positioning devices 45 of the supporting mechanism 4 and the sixth calibrating and positioning devices are matched for calibrating and positioning, the guide shoes 5a-6 stretch out to the vertical guide rails 5a-2, and the electricity collection clips 5a-7 stretch out to the trolley conductors 5a-3.

(103) (9) The movement gears 5a-4 are driven to move upwards by the first motor 5a-5 until the supporting mechanism 4 leaves the first supplementary rails 32.

(104) (10) The first supplementary rails 32 are driven to horizontally open to both sides of the supporting mechanism 4 by the fifth push rods 33, so that the supporting mechanism 4 can move downwards.

(105) (11) The movement gears 5a-4 are driven to move downwards by the first motor 5a-5; and when the supporting mechanism 4 needs to stay on a storage layer 1 for picking up the goods 8 or catching the empty self-delivering trolley 6, the first motor 5a-5 brake and stop rotating, and the first telescopic tongues 421 stretch into the trumpet openings of the forcible leveling female seats 31 on the layer, so as to realize forcible indirect precise positioning of the supporting mechanism 4 on the layer.

(106) (12) The supporting mechanism 4 needs to move upwards a short distance when the supporting mechanism 4 is about to leave the leveling position, so that the forcible leveling devices 42 are not pressed and are recovered to a suspension state; the first telescopic tongues 421 draw back in place, and then the confirmation signals are sent to the control system; and next, the movement gears 5a-4 are driven to move downwards onto the third rails 73 on the lowermost layer of the shaft 3 on the left side by the first motor 5a-5.

(107) (13) The supporting mechanism 4 is supported by the third rails 73, and the guide shoes 5a-6 and the electricity collection clips 5a-7 draw back.

(108) (14) If the self-delivering trolley 6 is empty at the moment, the self-delivering trolley 6 needs to wait for loading of the goods 8 that need to be stored; and if the self-delivering trolley 6 is loaded with the goods 8 that need to be picked up, the supporting mechanism 4 moves horizontally rightwards to the lowermost layer of the shaft 3 on the right side, and the goods 8 are unloaded.

(109) Through the major cycle of the supporting mechanism 4 and the minor cycle of the self-delivering trolley 6, the goods 8 are quickly and efficiently stored and picked up in rush hours of storage and pick-up of the goods 8.
