DETAILED DESCRIPTION

[0046] FIGS. 1 and 2 will be discussed first. According to FIG. 1, a mounting system 10 for carrying out automated mounting steps has a displacement component in the form of a winch 12, which is arranged on a shaft ceiling 14 of a shaft in the form of an elevator shaft 16. The elevator shaft 16 is delimited by a total of four shaft walls, of which only a first shaft wall 18 and a second shaft wall 20 located opposite the first shaft wall in a fixing direction 40 are shown in FIG. 1. FIG. 2 also shows a third shaft wall 19 and a fourth shaft wall 21 located opposite the third shaft wall 19. According to FIG. 2, the elevator shaft 16 has a mainly rectangular cross-section and extends mainly in the vertical direction, being delimited at the top by the shaft ceiling 14. A shaft floor opposite the shaft ceiling 14 is not shown. The second shaft wall 20 has an opening in the form of a door opening 23 into which a shaft door is inserted when an elevator installation is installed in the elevator shaft 16.

[0047] The winch 12 is connected to a mounting frame 24 of a mounting device 26 for carrying out automated mounting steps in the elevator shaft 16 via a carrier means in the form of a cable 22. For this purpose, the mounting frame 24 is suspended on the cable 22 via a suspension device 13 in the form of a bail. The cable 22 can be wound up or unwound by the winch 12 and the mounting frame 24 and thus the mounting device 26 can therefore be displaced in the elevator shaft 16, i.e. pulled up and let down. The mounting frame 24 and thus the mounting device 26 can therefore be displaced in a vertically extending displacement direction 27 in the elevator shaft 16. A mechatronic installation component in the form of an industrial robot 28 is arranged on the mounting frame 24, by means of which component automated mounting steps can be carried out in the elevator shaft 16. The industrial robot 28 is designed, for example, like an industrial robot described in WO 2017/016780 A1 and can, for example, automatically carry out the mounting steps described therein.

[0048] The mounting frame 24 and the industrial robot 28 thus form the mounting device 26 for carrying out automated mounting steps. The mounting device 26, the cable 22, and the winch 12 thus form the mounting system 10 for carrying out automated mounting steps.

[0049] The mounting frame 24 has a multi-part main frame 30. The main frame 30 has a mainly cuboid middle part 32 on which the industrial robot 28 is arranged so as to hang downward. The suspension device 13 mentioned above is arranged on the middle part 32 and thus on the main frame 30 at the top toward the shaft ceiling 14. The suspension device 13 can be fixed at different points on the middle part 32 with respect to the fixing direction 40 and is therefore designed to be movable relative to the main frame 30 in the fixing direction 40. The middle part 32 can accommodate other components (not shown) of the mounting device 26 or of the mounting frame 24, such as a control device and/or a compressor for providing compressed air. The middle part 32 can be closed off from the outside by a housing (not shown). A side of the middle part 32 oriented toward the second shaft wall 20 forms a second side 47 of the main frame 30.

[0050] The middle part 24 is adjoined by two horizontally extending transverse bars 34a and 34b which are spaced apart from one another in the displacement direction 27. The transverse bars 34a, 34b are constructed in two parts, with a first part 36a, 36b arranged toward the middle part 32 being able to be pushed into a second part 38a, 38b arranged toward the first shaft wall 18. The two parts 36a and 38a or 36b and 38b can be secured relative to one another by means of a bolt (not shown). The extension of the main frame 30 in the fixing direction 40, which extends horizontally and perpendicularly to the first shaft wall 18 and to the second shaft wall 20, can thus be changed.

[0051] The two transverse bars 34a, 34b are connected toward the first shaft wall 18 to a longitudinal bar 42 extending in the displacement direction 27. The longitudinal bar 42 forms a first side 45 of the main frame 30. At the lower end of the longitudinal bar 42, there are two horizontal beams 43 which protrude into the elevator shaft 16 and which, when the mounting device 26 is in operation, can carry one or more magazines with mounting material, such as screws or anchor bolts. The main frame 30 is thus made up of the middle part 32, the two transverse bars 34a, 34b, the longitudinal bar 42, and the beams 43. The aforementioned parts of the main frame 30 are connected to one another in a suitable manner, for example plugged, screwed, or welded. They are each made of suitable metal profiles, for example.

[0052] A total of four pairs consisting of a support component 44 and a primary fixing component 46 are arranged on the longitudinal bar 42 toward the first shaft wall 18. The support components 44 and the primary fixing components 46 are arranged in such a way that they each form the corners of a rectangle of which the edges extend in the displacement direction 27 and in a transverse direction perpendicular to the displacement direction 27 and to the fixing direction 40, with the primary fixing components 46 being arranged further to the outside in the displacement direction 27 relative to the support components 44.

[0053] The primary fixing components 46 are designed as rubber buffers, which are arranged on the longitudinal bar 42 so as to be immovable relative to the bar. They are therefore also arranged on the main frame 30 so as to be immovable relative to the main frame. Each support element 44 has a roller 48 which can be rotated about an axle (not shown) and which can roll along the first shaft wall 18 in the displacement direction 27. The axle of the roller 48 is fastened to the longitudinal bar 42 via a holder 50 so as to be movable in the fixing direction 40. For this purpose, the holder 50 can have a corresponding slot (not shown). An energy store in the form of a helical spring 52 is arranged between the longitudinal bar 42 and the axle of the roller 48 in such a way that it pushes the roller 48 against the first shaft wall 18, so that the roller 48 and thus the support component 44 is in contact with or supported against the first shaft wall 18 via a support surface 54.

[0054] A stabilizing element 6 is also arranged at the lower end of the longitudinal bar 42 toward the first shaft wall 18. The stabilizing element 6 has a roller 7 which is pressed against the first shaft wall 18 by the longitudinal bar 42 via an energy store in the form of a spring 8. When the mounting frame 24 is displaced in the elevator shaft 16, the roller 7 of the stabilizing element 6 rolls against the first shaft wall 18. The stabilizing element 6 also has a fixing element in the form of a pneumatic brake 9, which can be supplied with compressed air and thus activated via a compressed air line (not shown). In the activated state, the pneumatic brake 9 fixes the roller 7 relative to the longitudinal bar 42 and thus relative to the main frame 30. In the state of the mounting device 24 shown in FIGS. 1 and 2, in which it can be displaced in the elevator shaft 16, the pneumatic brake 9 is not activated, so that the roller 7 can be displaced toward the longitudinal bar 42 against the force of the spring 8.

[0055] A secondary fixing component 56 is arranged on the middle part 32 of the main frame 30 toward the second shaft wall 20. An actuating bolt 58 extending in the fixing direction 40 is mounted in the middle part 32 and protrudes from the middle part 32 toward the second shaft wall 20. The actuating bolt 58 can be displaced, i.e. extended out of the middle part 32 and retracted into the middle part 32, in the fixing direction 40 by means of two actuators in the form of an electric spindle drive 60. The actuating bolt 58 is connected via an intermediate piece 62, which also extends in the fixing direction 40, to a contact element 64 which is elongate in the displacement direction 27. The actuating bolt 58 is inserted into the intermediate piece 62 and can be secured in various positions relative to the intermediate piece 62 with a bolt (not shown). In this way, a spacing between the contact part 64 and the middle part 32 and thus the main frame 30 in the fixing direction 40 can also be changed independently of the spindle drives 60 of the secondary fixing component 56.

[0056] The contact part 64 is multi-part. A middle piece 66 is securely connected to the intermediate piece 62. The middle piece 66 is adjoined in the displacement direction 27 at the top and bottom by an end piece 68 that can be easily mounted and dismounted.

[0057] In FIGS. 1 and 2, the four support components 44 are in the displacement position. The rollers 48 protrude beyond the primary fixing components 46 toward the first shaft wall 18. The support surfaces 54 on the rollers 48 are thus arranged further outward in the fixing direction 40, i.e. toward the first shaft wall 18, from the main frame 30 than the entire primary fixing component 46. In addition, the contact part 64 of the secondary fixing component 56 is in the displacement position. The contact part 64 is therefore not in contact with the second shaft wall 20; rather, it is at a spacing from the second shaft wall 20 in the fixing direction 40.

[0058] In this state of the mounting frame 24 and thus the mounting device 26, the frame can be displaced in the displacement direction 27 in the elevator shaft 16 by means of the winch 12 and the cable 22 and thus positioned at different heights. The mounting frame 24 is supported against the first shaft wall 18 via the support surfaces 54 of the rollers 48. The rollers 48 roll on the first shaft wall 18.

[0059] In order to fix the mounting frame 24 and thus the mounting device 26 in the elevator shaft 16, the contact part 64 of the secondary fixing component 56 is displaced outward, i.e. away from the main frame 30, by means of the two spindle drives 60 toward the second shaft wall 20. As long as the contact part 64 has not reached the second shaft wall 20, the support elements 44 remain in the displacement position shown in FIGS. 1 and 2. When the contact part 64 is in contact with the second shaft wall 20 and the actuating bolt 58 is extended further from the middle part 32, the entire main frame 30, together with all the parts arranged thereon so as to be immovable, is displaced toward the first shaft wall 18. The helical springs 52 of the support elements 44 are then compressed until the primary fixing components 46 rest against the first shaft wall 18 via fixing surfaces 74 (see FIG. 3). The mounting frame 24 is thus secured or braced, and thus fixed, between the first shaft wall 18 and the second shaft wall 20.

[0060] When the mounting frame 24 is fixed in the manner described, the roller 7 of the stabilizing element 6 is also displaced against the force of the spring 8 toward the longitudinal bar 42 and thus toward the main frame 30.

[0061] In FIG. 3, the mounting frame 24 is shown in the fixed state. The contact part 64 of the secondary fixing component 56 is in its fixing position here, in which it is in contact with the second shaft wall 20 and is thus spaced further outward from the main frame 30 toward the second shaft wall 20 than in the displacement position. In addition, the support components 44 are in their fixing position, in which no part of the support surfaces 54 is spaced further outward in the fixing direction 40, i.e. toward the first shaft wall 18, from the main frame 30 than the fixing surfaces 74 of the primary fixing components 46. Since the rollers 48 are also in contact with the first shaft wall 18 in this state, the support surfaces 54 and the fixing surfaces 74 are spaced outward in the fixing direction 40 from the main frame 30 by the same amount.

[0062] When the mounting frame 24 is in the fixed state, the pneumatic brake 9 of the stabilizing element 6 is also activated by applying compressed air. The roller 7 is thus fixed relative to the longitudinal bar 42 and thus relative to the main frame 30 so that it can no longer be displaced any further toward the longitudinal bar 42. Forces acting on the longitudinal bar 42 toward the first shaft wall 18 can thus be supported against the first shaft wall 18 via the roller 7 of the stabilizing element 6. It is also possible for the pneumatic brake 9 of the stabilizing element 6 to be activated only when the mounting frame 24 is actually used for mounting work in the elevator shaft 16.
