DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(21) In order to make the technical features, the propose and the technical effect of the present application more clearly, the present application will now be described in detail with reference to the accompanying drawings and embodiments.

(22) As shown in FIGS. 1-19, the present application provides a sealed and integrated climbing scaffold comprising a hollow frame structure 1, a plurality of mechanical arm devices 3, a plurality of climbing fulcrums 5, a lifting system 6, and a construction operation platform structure 7.

(23) The hollow frame structure 1 includes an inner guide rail 101 and an outer guide rail 102, and the inner guide rail 101 and the outer guide rail 102 are assembled together. At least two of the mechanical arm devices 3 (the mechanical arm device 3a and 3c) are fixed on the inner guide rail 101, and the height interval between the two mechanical arm devices 3 fixed on the inner guide rail 101 is equal to a height of one floor. At least two of the mechanical arm devices 3 (the mechanical arm device 3b and 3d) are fixed on the outer guide rail 102, and the height interval between the two mechanical arm devices 3 fixed on the outer guide rail 102 is equal to the height of one floor, too. The climbing fulcrums 5 are configured to be fixed on an architectural structure, for example, to be fixed on every floor of a building. The construction operation platform structure 7 is fixedly connected with the outer guide rail 102, and can be driven to move up and down by the outer guide rail 102. Each of the mechanical arm devices 3 includes a catch-and-release structure configured for capturing the climbing fulcrums 5, and each of the climbing fulcrums 5 can be provided with a cooperation structure, such as a cross-bar, a locating hole, or other structures, to cooperate with the catch-and-release structure. The inner guide rail 101 and the outer guide rail 102 are connected with the lifting system 6 respectively. The lifting system 6 is received in the hollow frame structure 1 to be well protected and insulated from outside pollution. The outer guide rail 102 includes a guide rail upright pole 103, two connecting plates 104, a left slide way 105 and a right slide way 106. The two connecting plates 104 are respectively fixed on the left side and the right side of the guide rail upright pole 103 by pins, rivets, or other connecting methods. The left slide way 105 and the right slide way 106 are fixedly connected with the two connecting plates 104 respectively by pins, rivets, or other connecting methods. The guide rail upright pole 103, the connecting plates 104, the left slide way 105, and the right slide way 106 are all made of aluminum alloy section bar, which is not only light in weight but also easy to be manufactured and molded. The outer guide rail 102 is formed by a plurality of components combined together. The outer guide rail 102 is simple in structure, convenient to be assembled, and has good sealing performance.

(24) The mechanical arm devices 3 of the sealed and integrated climbing scaffold can capture the climbing fulcrums 5 by the catch-and-release structures. In the lifting process, either the outer guide rail 102 or the inner guide rail 101 can be elevated at first. For example, if the inner guide rail 101 needs to be elevated at first, the lifting system 6 elevates the inner guide rail 101 at first. During the lifting process, the outer guide rail 102 is held still and provides supporting and locating functions which are similar to the functions of a guide base in the prior art. When the mechanical arm devices 3 on the inner guide rail 101 move up to reach an upper one of the climbing fulcrums 5 and catch this climbing fulcrum 5, elevating the inner guide rail 101 is stopped and elevating the outer guide rail 102 is started. At present, the inner guide rail 101 is held still and provides supporting and locating functions until the mechanical arm devices 3 on the outer guide rail 102 move up to reach a higher one of the climbing fulcrums 5 and catch the higher climbing fulcrum 5. The descending process of the sealed and integrated climbing scaffold is similar to the lifting process, wherein the mechanical arm devices 3 on the inner guide rail 101 and the mechanical arm devices 3 on the outer guide rail 102 move alternately, too. In the present application, the outer guide rail 102 and the inner guide rail 101 of the sealed and integrated climbing scaffold act as a guide base and a guide rail alternately. Therefore, the sealed and integrated climbing scaffold of the present application can imitate the principal of human climbing movements by using the mechanical arm devices 3 fixed on the inner guide rail 101 and the outer guide rail 102 to move up and down, and thereby realize lifting and descending of high-rise construction platforms. The present application reduces the work of carrying guide bases of high-rise construction lifting platforms and the work of connecting and disconnecting attachment lifting points of high-rise construction lifting platforms, improves the levels of mechanization and automation in construction, and reduces workers' labor intensity. In one building, only one person can easily realize the work of elevating and descending the high-rise construction lifting platform, which can greatly improve the construction efficiency and save much workforce. The components of the hollow frame structure 1 of the present application are simple in assembly, and the hollow frame structure 1 realizes standardization and modularization. Therefore, these components can be assembled together in a factory, and the hollow frame structure 1 has good sealing performance. In this way, the lifting system 6 in the hollow frame structure 1 can be effectively protected, and the equipment failure rate can be reduced.

(25) Each of the two connecting plates 104 includes a plurality of sub-plates (such as the sub-plates 104a and 104b in FIG. 2) combined together. Every sub-plate is small in size, and is convenient to be manufactured and carried. When the inner part of the hollow frame structure 1 is repaired, any one of the sub-plates can be selectively detached, and the stability of the whole climbing scaffold is not affected. Thus, the sealed and integrated climbing scaffold is simple in structure, and is convenient to maintain.

(26) A dust-proof cover 2 is mounted at the top of the hollow frame structure 1. A plurality of dust-seal plates 4 cover a moving gap formed between each end of the inner guide rail 101 and an inner wall of the outer guide rail 102. A dust shield 10 is mounted outside the lifting system 6. All these designs can further improve dustproof effect and sealing performance of the sealed and integrated climbing scaffold. In this embodiment, the dust shield 10 is fixed on a mounting bracket 107.

(27) The hollow frame structure 1 further includes the mounting bracket 107. The guide rail upright pole 103, the bottom of the left slide way 105, and the bottom of the right slide way 106 are all connected with the mounting bracket 107. The mounting bracket 107 is configured to improve the stability of the whole hollow frame structure 1, and to seal the bottom of the hollow frame structure 1.

(28) As shown in FIG. 5, each of the climbing fulcrums 5 in this embodiment includes a pedestal 501 and a pin shaft 502. The pin shaft 502 is fixed on the pedestal 501, and an anti-off pin 503 can be mounted at one end of the pin shaft 502. The pin shaft 502 is configured to be caught by the catch-and-release structure, so that the mechanical arm device 3 is fixed on the climbing fulcrum 5. It is understandable that using the pedestal 501 and the pin shaft 502 is just one preferable method, and the climbing fulcrum 5 can also be realized by using through-holes, grooves, or other methods.

(29) As shown in FIGS. 10-14, each of the mechanical arm devices 3 includes a mechanical arm 301, an axle 304, and a supporting base 302. The mechanical arm 301 is rotatably connected with the supporting base 302 via the axle 304, and components such as gaskets, circlips, and so on, can be mounted at one end of the axle 304 to prevent the axle 304 separating from the supporting base 302. An outside protective cover 303 is mounted on the supporting base 302. The mechanical arm device 3 further includes a locking device, which includes a stop block 305, a solenoid valve 306, a lock plate 307, a dragging cable 308, a locating sleeve 312, a first spring 309, and a mounting plate 311. The stop block 305 is movable, and the mechanical arm 301 can be locked on any one of the climbing fulcrums 5 while the stop block 305 extends out of the locking device. An open slot 321 is defined in a distal end of the mechanical arm 301, and the catch-and-release structure of the mechanical arm devices 3 includes the open slot 321 and the locking device. When the stop block 305 extends outside, the mechanical arm 301 is locked on one of the climbing fulcrums 5; and when the stop block 305 retracts, the mechanical arm 301 is released from the climbing fulcrum 5. The catch-and-release structure in this embodiment is just one preferable method, and the catch-and-release structure can also be realized by using a mechanical hand or other devices.

(30) One end of the dragging cable 308 is connected with the stop block 305. Particularly, one end of the dragging cable 308 extends into the stop block 305, and is mounted on the stop block 305 and limited by the lock plate 307. Since the end of the dragging cable 308 connected with the stop block 305 has a large head part, the lock plate 307 is stuck between the head part and the stop block 305, which ensures that the dragging cable 308 does not separate from the stop block 305. When the dragging cable 308 is pulled to move, the stop block 305 can move correspondingly. The other end of the dragging cable 308 is connected with the solenoid valve 306. When the solenoid valve 306 is powered on and closed, the dragging cable 308 is pulled and drives the stop block 305 to move away from the mechanical arm 301. In order to further limit the dragging cable 308, the locating sleeve 312 is sheathed on the dragging cable 308, and the locating sleeve 312 is further fixed on the mounting plate 311. One end of the first spring 309 abuts against the mounting plate 311, and the other end of the first spring 309 abuts against either the lock plate 307 or the stop block 305. The first spring 309 provides restoring force to drive the stop block 305 to move toward the mechanical arm 301. When the solenoid valve 306 is powered on and closed, the dragging cable 308 is pulled and drives the stop block 305 to retract, that is, the stop block 305 moves away from the mechanical arm 301. Thus, the mechanical arm 301 can't be locked on the climbing fulcrum 5. Meanwhile, the first spring 309 is contracted. When the solenoid valve 306 is powered off, the stop block 305 extends out and moves towards the mechanical arm 301, so that the mechanical arm 301 is locked on embedded parts in the building. It is understandable that the locking device in this embodiment is just one preferable method, and can also be realized by other methods, as long as the stop block 305 can be enabled to extend and retract and thereby finish the locking and releasing actions.

(31) As shown in FIG. 10 and FIG. 14, each of the mechanical arm devices 3 further includes a second spring 313 and a trigger-rod 314. The trigger-rod 314 is rotatably connected with the supporting base 302. In this embodiment, the trigger-rod 314 is mounted on the supporting base 302 via a fixed bolt 420. The trigger-rod 314 is configured to hold the mechanical arm 301 and prevent the mechanical arm 301 from rotating. In this embodiment, a limiting notch 315 is defined in the trigger-rod 314, and a limiting pin 316 is mounted on the mechanical arm 301. Understandably, the position where the limiting notch 315 is defined and the position where the limiting pin 316 is mounted are interchangeable, that is, the limiting notch 315 can be defined in the mechanical arm 301 and the limiting pin 316 can be mounted on the trigger-rod 314. The means for enabling the trigger-rod 314 to hold the mechanical arm 301 is not limited to the use of the limiting notch 315 and the limiting pin 316, and can also be realized by using hooks or other methods. Two ends of the second spring 313 are respectively fixed on the supporting base 302 and the trigger-rod 314. Particularly, a connecting screw 318 is mounted on the supporting base 302, and one end of the second spring 313 is fixed on the connecting screw 318. While the trigger-rod 314 is rotating, the second spring 313 is stretched and provides restoring force to drive the trigger-rod 314 to rotate in reverse.

(32) As shown in FIG. 10 and FIG. 14, a third spring 317 is connected with the mechanical arm device 3, and two ends of the third spring 317 are fixed on the supporting base 302 and the mechanical arm 301 respectively. In particular, a fixing screw 319 is mounted on the supporting base 302, and a fixing pin 310 is mounted on the mechanical arm 301. Two ends of the third spring 317 are respectively fixed on the fixing screw 319 and the fixing pin 310. While the bottom of the mechanical arm 301 is rotated inwards and the top of the mechanical arm 301 is rotated outwards, the third spring 317 is stretched. Thus, the trigger-rod 314 is rotated to hold the limiting pin 316 in the limiting notch 315, and the second spring 313 is stretched too. In this situation, neither the trigger-rod 314 nor the mechanical arm 301 can rotate without external force. If the external force makes the limiting pin 316 separate from the limiting notch 315, the trigger-rod 314 and the mechanical arm 301 will return under the actions of the second spring 313 and the third spring 317.

(33) As shown in FIGS. 6-9 and FIG. 15, the lifting system 6 includes an electric hoist 601 and a gravity sensor 602. A dragging hook and a dragging chain are mounted on the electric hoist 601, and the dragging hook is connected with the gravity sensor 602. The structures of the electric hoist 601 and the gravity sensor 602 are prior art, therefore, they do not need to be detailed here. The outer guide rail 102 includes an up-loop hook 201 and a down-loop hook 202, and the inner guide rail 101 includes a hanging base 108. One end of the dragging chain runs through the up-loop hook 201 and then is fixed on the hanging base 108, and the other end of the dragging chain runs through the down-loop hook 202 and then is fixed on the electric hoist 601. The inner guide rail 101 and the outer guide rail 102 can be elevated by the electric hoist 601. A pressure spring 109 is mounted on the hanging base 108. Under the action of the pressure spring 109, the dragging chain of the electric hoist 601 can be tightened to ensure the lifting effect.

(34) FIG. 16 shows another embodiment of the lifting system 6. The lifting system 6 of the another embodiment also includes the electric hoists 601 and the gravity sensor 602, the dragging hook and the dragging chain are mounted on the electric hoists 601, and the dragging hook is connected with the gravity sensor 602. The hanging base 108 is mounted on the inner guide rail 101, and the dragging chain runs through a chain wheel of the electric hoist 601 and a chain wheel of the hanging base 108 to form a closed chain. A connector 203 is mounted on the outer guide rail 102, and the connector 203 is fixedly connected with the dragging chain of the electric hoist 601. The inner guide rail 101 and the outer guide rail 102 can be elevated by the electric hoist 601. Except above two embodiments, the lifting system 6 can also adopt other methods, such as chain driving or gear driving, to realize the lifting operations. The two embodiments just show two preferable methods.

(35) The sealed and integrated climbing scaffold further comprises a falling protector 8 and an anti-falling rod 10. The falling protector 8 is fixed on the outer guide rail 102, and the anti-falling rod 10 is fixed on the inner guide rail 101. The falling protector 8 cooperates with the anti-falling rod 10 to prevent the sealed and integrated climbing scaffold from falling. The detailed structures for prevent the sealed and integrated climbing scaffold from falling are prior art, and thus they do not need to be detailed here. The falling protector 8 in this embodiment is a rotary wheel falling protector, and it can also be a pendular needle falling protector or other anti-falling devices.

(36) The sealed and integrated climbing scaffold further comprises a retainer 9 and a plurality of embedded screws 504. The retainer 9 includes a fixing base 901, a locating and supporting arm 902, and a rotating shaft 903. Each of the embedded screws 504 is fixedly connected with each of the climbing fulcrum 5, and any one of the embedded screws 504 is capable of being detachably connected with the locating and supporting arm 902. The fixing base 901 is mounted on either the inner guide rail 101 or the outer guide rail 102, the locating and supporting arm 902 is rotatably connected to the fixing base 901 by the rotating shaft 903, and the locating and supporting arm 902 is capable of rotating around the rotating shaft 903. A stop pin 904 is mounted on the locating and supporting arm 902, and a first notch 905 and a second notch 906 are defined in the fixing base 901 to cooperate with the stop pin 904. The retainer 9 is configured of determine the location of the embedded screw 504. While the locating and supporting arm 902 is rotated to be perpendicular to the outside surface of a building, the stop pin 904 cooperates with the first notch 905 for limitation. The embedded screw 504 mounted on the locating and supporting arm 902 is maintained at the position of an appointed storey. When constructing the appointed storey, the embedded screw 504 is wrapped in the building materials, such as concrete. The embedded screw 504 is fixed on the appointed storey after the concrete is solidified, so that it is convenient to assemble the climbing fulcrum 5. By using the retainer 9, the location of the embedded screw 504 can be accurately determined, and the work of pre-burying the embedded screw 504 becomes more convenient. Having fixed the embedded screw 504, the embedded screw 504 is separated from the locating and supporting arm 902, the locating and supporting arm 902 is rotated to be parallel to the outside surface of the building, and the stop pin 904 cooperates with the second notch 906 for limitation.

(37) The present application also provides a method for using the aforementioned sealed and integrated climbing scaffold, which comprises the following steps:
