DETAILED DESCRIPTION

(12) FIG. 1 shows an elevator shaft 103 of an elevator system in which a mounting system 1 is arranged. The mounting system 1 has a mounting apparatus 5 with a carrier component 3 and a mechatronic installation component 7. The carrier component 3 is configured as a frame on which the mechatronic installation component 7 is mounted. This frame has dimensions that enable the carrier component 3 to be displaced vertically within the elevator shaft 103, thus along the perpendicular or vertical 104, that is, to move it to different vertical positions on different floors within a building, for example. The mechatronic installation component 7 is configured in the form of an industrial robot that is attached hanging downwards from the frame of carrier component 3. One arm of the industrial robot can be moved relative to the carrier component 3 and, for example, can be displaced towards or away from a shaft wall 105 of the elevator shaft 103.

(13) The carrier component 3 is connected via a steel cable serving as suspension means 17 to a displacement component 15 (see FIG. 2) in the form of a motor-driven cable winch which is hidden in FIG. 1 and therefore not visible (see FIG. 2) and which is attached at the top in the elevator shaft 103 to a shaft ceiling 107 (see FIG. 2) of the elevator shaft 103. Between the displacement component 15 and the carrier component 3, the suspension means 17 is guided via a deflection roller 34 (see FIG. 2) which is hidden in FIG. 1 and is therefore not visible. By means of the displacement component 15, the mounting apparatus 5 can be displaced vertically within the elevator shaft 103 over the entire length of the elevator shaft 103.

(14) The mounting apparatus 5 further includes a fixing component 19, by means of which the carrier component 3 can be fixed within the elevator shaft 103 in a lateral direction, that is, in a horizontal direction. The fixing component 19 on the front side of the carrier component 3 and/or the pad (not shown) on a rear side of carrier component 3 can be moved outwards to the front or rear for this purpose and thus fix the carrier component 3 in place between walls 105 of the elevator shaft 103.

(15) The industrial robot can be coupled at its cantilevered end with various mounting tools, which are not shown in more detail. The mounting tools can differ in their design and their intended use. With these mounting tools, mounting steps can be performed semi-automatically or fully automatically in a fixed state of the mounting apparatus.

(16) Furthermore, a magazine component, which is not shown in detail, can be provided on the carrier component 3. The magazine component can be used to store components to be installed and to provide them to the industrial robot 7. For example, the magazine component can accommodate various components, in particular in the form of different profiles, which are to be mounted on the shaft walls 105 within the elevator shaft 103, for example to be able to attach guide rails for the elevator system thereon. The magazine component can also be used to store and provide screws that can be screwed into prefabricated holes in the shaft wall 105 with the aid of the industrial robot 7.

(17) Furthermore, support rollers, which are not shown in FIG. 1 (upper support rollers 21 and lower support rollers 22 in FIG. 2), are provided on the carrier component 3, by means of which support rollers the carrier component 3 is guided during vertical displacement within the elevator shaft 103 along a shaft wall denoted hereinafter as supporting wall 108. The supporting wall 108 is the shaft wall that is located opposite to door openings 106 of the elevator shaft 103. During the displacement of the mounting apparatus 5, the support rollers roll on the supporting wall 108. Depending on the arrangement of the support rollers on the carrier component, one to four support rollers, in particular, can be provided.

(18) FIG. 2 shows a side view of the mounting apparatus 1, wherein only the carrier component 3, the upper support rollers 21 and the lower support rollers 22 are shown of the mounting apparatus 5. The displacement component 15 is suspended from the shaft ceiling 107. The shaft ceiling 107, the shaft walls 105 and a shaft floor 102 define the elevator shaft 103 and can be designated as boundary surfaces of the elevator shaft 103.

(19) The suspension means 17 runs downwards from the displacement component 15, via a deflection roller 34, to a suspension point 38 of the suspension means 17 on the carrier component 3. The suspension point 38 is located exactly above a center of gravity 36 of the mounting apparatus 5. The suspension means 17 first runs inclined with respect to the vertical 104 from the displacement component 15 towards the supporting wall 108 and is then deflected by the deflection roller 34 in such a way that after the deflection roller 34, it runs inclined away from the supporting wall 108. A displacement of the deflection roller 34 in horizontal or vertical direction changes the deflection and thus the direction of the suspension means 17.

(20) The suspension means 17 thus has a diagonal pull α between the deflection roller 34 and the carrier component 3 in the direction of the supporting wall 108. The mentioned diagonal pull α corresponds to the angle that the suspension means 17 forms with the perpendicular or vertical 104 in the direction of the supporting wall 108. Due to the diagonal pull α, a holding force acting on the carrier component 3 via the suspension means 17 has a horizontal component 39 in the direction of the supporting wall 108. The horizontal component 39 causes a horizontal reaction force 40 in the opposite direction at the deflection roller 34.

(21) Below the deflection roller 34, an installation platform 41 is arranged in the elevator shaft 103 in such a way that an installer is able to install the deflection roller 34 and the displacement component 15 from the installation platform 41. In particular, the displacement component 15 is suspended from the shaft ceiling 107 by a suspension device that is not shown here and that is already provided during the construction of the elevator shaft 103. The deflection roller 34 is fixed to the supporting wall 108 via a holding apparatus 35 in such a way that it protrudes into the elevator shaft 103. The installation of the deflection roller 34 is explained in more detail in connection with FIG. 3.

(22) The carrier component 3 has a pair of upper support rollers 21 and a pair of lower support rollers 22. The upper support rollers 21 are arranged in an upper region and the lower support rollers 22 are arranged in a lower region of carrier component 3. The upper support rollers 21 are arranged below the suspension point 38 at which the carrier component 3 is suspended from the suspension means 17. The suspension point 38 is at the same time also a force transmission point at which the holding force is introduced from the suspension means 17 into the carrier component 3. The carrier component 3 is supported on the supporting wall 108 via the support rollers 21, 22. If the diagonal pull α of the supporting means 17 in the direction of the supporting wall 108 and thus the horizontal component 39 of the holding force of the carrier component 3 becomes too large, tilting of the carrier component 3 about the upper support rollers 21 can occur. In order to counteract the increase of the diagonal pull α in the direction of the suspension means 17 between the deflection roller 34 and the carrier component 3 when a first distance s1 between the deflection roller 34 and the carrier component 3 decreases, a compensating element 24, shown in FIG. 3, is arranged on the holding apparatus 35 of the deflection roller 34.

(23) According to FIG. 3, the holding apparatus 35 has a fixing part 42 and a pivot arm 43. The fixing part 42 is screwed to the supporting wall 108 via screws, which are not shown. The fixing part has a cylindrical recess, which is not visible in FIG. 3, into which a bolt 44 is inserted via which the pivot arm 43 is pivotally connected to the fixing part 42. The pivot arm 43 can be pivoted about the bolt 44 so that the bolt 44 forms a pivot axis of the pivot arm 43. The bolt 44 and thus the pivot axis runs horizontally and parallel to the supporting wall 108. In FIG. 3, the pivot arm 43 is aligned horizontally and is held in this position by the suspension means 17.

(24) The pivot arm 43 has an elongated hole 45 which is aligned in a main direction of extent of the pivot arm 43 and thus horizontally in FIG. 3. One axis 46 of the deflection roller 34 runs through the slot 45 and is aligned parallel to the bolt 44. The axis 46 can be moved in the slot 45 relative to the pivot arm 43 and thus horizontally in FIG. 2. Therefore, a second distance s2 between the deflection roller 34 and the supporting wall 108 can be changed, thus increased or decreased. Between an end 48 opposite the fixing part 42 and the axis 46, a coil spring 49 is arranged in such a way that it applies a force to the axis 46 and thus to the deflection roller 34 in the direction of the supporting wall 108.

(25) When the carrier component 3 is pulled upwards in the elevator shaft 103, the first distance s1 between the deflection roller 34 and the carrier component 3 decreases. As a result, the horizontal component 39 of the holding force and thus also the reaction force 40 increases. Thereby, the deflection roller 34 including axis 46 is moved away from the supporting wall 108 against the force of the coil spring 49, thus the second distance s2 is increased. The compensating element 24 thus counteracts an increase in the diagonal pull α of the suspension means 17 when the first distance s1 between the deflection roller 34 and the carrier component 3 decreases.

(26) It is also possible that no compensating element is arranged on the holding apparatus. In this case, the axis of the deflection roller is fixed at a fixed position within the slotted hole of the pivot arm, for example by means of suitable nuts. In this case, the diagonal pull of the suspension means at a certain position of the support element can be adjusted, for example, during installation of the deflection roller, by determining the position of the axis of the deflection roller.

(27) In the mounting system 1 according to FIG. 4, a compensating element 124 is located at the top of carrier component 3. The suspension means 17 is fixed to the carrier component 3 via a suspension element 127 which can be moved in a vertical direction to the supporting wall 108. The compensating element 124 has two springs 125 which are arranged on opposite sides of the suspension element 127 with respect to the supporting wall 108 and thus each of them exerts a holding force on the suspension element 127. The ends of the springs 125 opposite to the suspension element 127 are fixed stationarily with respect to the carrier component 3 in a manner not shown in more detail. The suspension element 127 has a third distance s3 from the supporting wall 108.

(28) If the mounting apparatus 5 is now displaced upwards and thus the first distance s1 between deflection roller 34 and mounting apparatus 5 decreases, the horizontal component of the holding force on the carrier component 3 increases and the suspension element 127 is pressed towards the supporting wall 108 and displaced against the force of the springs 125 towards the supporting wall 108. Thus, the mentioned third distance s3 decreases. This displacement of the suspension element 127 in turn counteracts the increase in the diagonal pull α of the suspension means 17 in the direction of the supporting wall 108. In doing so, an equilibrium is continuously established, which is mainly determined by the characteristics of the springs 125. By means of calculations or simple tests, the springs 125 can be designed in such a way that tilting of the mounting apparatus 5 can be reliably avoided.

(29) In the mounting system 1 according to FIG. 5, a suspension member 228 is arranged between the suspension means 17 and the carrier component 3, wherein the suspension means 17 and the suspension member 228 are connected via a connecting element 229. The suspension member 228 is designed as a cable sling, the ends of which are connected to the carrier component 3 on opposite sides with respect to the supporting wall 108. A compensating element 224 is arranged on the suspension member 228 and is configured such that it is able to move the connecting element 229 relative to the suspension member 228. For this purpose, the compensating element 224 is equipped with an actuator 230 in the form of an electric motor, which is only shown in FIG. 6 and by means of which the connecting element 229 can be moved relative to the suspension member 228. The actuator 230 can drive a drive roller 231. The suspension member 228 runs between the drive roller 231 and a pressure roller 232. The pressure roller 232 is pressed against the suspension member 228 and the suspension member is pressed against the drive roller 231 by means of a spring, which is not shown in FIG. 6. When the actuator 230 now drives the drive roller 231, the drive roller rolls on the suspension member 228, which allows the position of the connecting element 229 and thus a fourth distance s4 to the supporting wall 108 to be adjusted with respect to the suspension member 228.

(30) The actuator 230 is controlled by a control device 237. The control device 237 adjusts the mentioned fourth distance as a function of an inclination of the carrier component 3. An inclination sensor 233 is installed at the bottom of the carrier component 3 to measure the inclination. The control device 237 measures the inclination and adjusts the fourth distance by means of a feedback control in such a way that the carrier component 3 is always vertically aligned, thus has no inclination. It is also possible that the control device 237 adjusts the fourth distance s4 as a function of the first distance s1 between the deflection roller 34 and the mounting apparatus 5. For this purpose, the control device 237 can measure the first distance directly by means of a distance sensor, which is not shown. It is also possible that the control device measures a distance to a floor of the elevator shaft 103 and determines the first distance therefrom. Furthermore, it is possible that the control device 237 detects how far the displacement component 15 displaces the mounting apparatus 5 in the elevator shaft 103 and determines the current first distance based on a first distance before the displacement. To determine the currently required fourth distance, a table is stored in the control device 237, in which table the fourth distance is stored as a function of the first distance. When the control device 237 has determined the current first distance, it can read out the currently required fourth distance from the table mentioned above and then adjust the distance with the help of the actuator 230.

(31) In FIG. 7, an alternative compensating element 524 to the compensating element 124 of FIG. 4 is illustrated. Instead of a spring, the compensating element 524 has an actuator 530 by means of which the suspension element 127 can be moved. The actuator 530 is configured as an electric motor which can extend and retract a positioning cylinder 533 acting on the suspension element 127. The actuator 530 is controlled by a control device 537, analogous to the actuator 230 in FIG. 6.

(32) The mounting system 1 according to FIG. 8 is structured very similar to the mounting system 1 according to FIG. 2, so that only the differences are discussed. To prevent the carrier component 3 from tilting about the upper support roller 21 in the direction of the supporting wall 108, the mounting system 1 has a compensating element 624. The compensating element 624 includes an actuator 630 connected to a balancing weight 635. The balancing weight 635 can be displaced relative to the carrier component 3 mainly in horizontal direction by means of the actuator 630. By moving the balancing weight 635, a center of gravity 636 of the mounting apparatus 5 can be moved and thus a fifth distance s5 of the center of gravity 636 to the supporting wall 108 can be changed or adjusted. The actuator 630 is controlled by a control device 637 in such a way that upon decreasing the first distance between the deflection roller 34 and the mounting apparatus 5, the fifth distance s5 of the center of gravity 636 of the mounting apparatus 5 to the supporting wall 108 is increased. The actuator 630 is controlled analogously to the actuator 230.

(33) The mounting system 1 according to FIG. 9 includes a compensating element 724 which basically functions in the same way as the compensating element 624 in FIG. 8. The difference is that in the mounting system 1 according to FIG. 9, the mechatronic installation component 7 in the form of the industrial robot is part of the compensating element 724 and is used as a balancing weight. In this case, the center of gravity 736 is moved by changing the position of the mechanical installation component 7 controlled by a control device 737.

(34) In the mounting system 1 according to FIG. 10, the upper support roller 21 is arranged on a spacer element 840 protruding upwards from the carrier component 3. A force transmission point 838, at which the holding force is introduced into the carrier component 3, is thus arranged below the upper support roller 21, in particular below an unmarked axis of rotation of the upper support roller 21. It would also be possible for the force transmission point to be arranged at the same height as the upper support roller. Thus, the horizontal component 839 of the holding force runs below the support roller 21. The torque 823 generated in this manner therefore cannot result in the lower support roller 22 lifting off from the supporting wall 108 and thus causing the carrier component 3 to tilt about the upper support roller 21. Rather, the lower support roller 22 is pressed against the supporting wall 108 by the torque 823. The upper support roller 21, the spacer element 840 and the force transmission point 838 thus form a compensating element 824 which counteracts the tilting of the carrier component 3 about the upper support roller 21 in the direction of supporting wall 108 during the displacement of carrier component 3 in the elevator shaft 103. In addition to the above-mentioned components, the compensating element can also include a suspension element, which is not shown, for example in the form of an eyelet, a hook or a through-hole of the carrier component.

It should also be noted that features or steps described with reference to one of the above exemplary embodiments can also be used in combination with other features or steps of other exemplary embodiments described above.
