DETAILED DESCRIPTION

(11) According to FIGS. 1a to 1c, a vertically extending elevator shaft 10 of an elevator system (not shown) has a first vertical car track 12 and a second vertical car track 14 arranged directly next to the first vertical car track 12. The two vertical car tracks 10, 12 are separated from one another by two dashed lines 16 in FIGS. 1a to 1c. In the fully mounted state of the elevator system, a plurality of steel girders are arranged at a vertical distance between the two lines 16 and separate the two vertical car tracks 12, 14 from one another. Guide rails are then fastened to the steel girders as well as to shaft walls 18 of the elevator shaft 10 opposite the steel girders, along which rails at least one elevator car is guided for each vertical car track 12, 14 during a displacement in the corresponding vertical car track 12, 14.

(12) A first vertical section 20 of the elevator shaft 10 is shown in FIGS. 1a to 1c. Above the first vertical section 20, the elevator shaft 10 is in particular not yet completely finished, but is still under construction. The first vertical car track 12 is closed off at the top by a first platform 22, which serves as a so-called protective platform. The first platform 22 protects the first vertical car track 12 from parts falling from above. The first platform 22 has a total of four extendable support beams 24 which are arranged at the bottom of the first platform 22 and can be extended horizontally in the direction of the shaft walls 18. In order to introduce the first platform 22 into the elevator shaft 10, the support beams 24 can be retracted inward beneath the first platform 22. The support beams 24 which are oriented in the direction of the shaft wall 18 are partially arranged in a niche 26 in the shaft wall 18 and are thus supported at the bottom. The two other support beams 24 oriented in the direction of the second vertical car track 14 rest on support elements 23 which are fixed in the elevator shaft 10 before the first platform 22 is introduced, and are thus supported at the bottom. The second vertical car track 14 is closed off at the top by a second platform 28 which is designed analogously to the first platform 22 and is supported at the bottom analogously to the first platform 22. It is also possible that the two platforms are designed as a single, common platform.

(13) A rail 32 is held beneath the two platforms 22, 28 by means of two vertically extending holding rods 30. Each holding rod 30 is fixed to one of the platforms 22, 28. The rail 32 is designed as a double-T beam, for example, and extends horizontally. It extends from the first vertical car track 12 into the second vertical car track 14 and thus in a shift direction D. A coupling device in the form of a roller arrangement 36 is guided in the rail 32 and can be shifted on the rail 32 by means of a horizontal drive (not shown) and thus shifted horizontally between the two vertical car tracks 12, 14.

(14) A displacement component 38 in the form of a winch is suspended from the roller arrangement 36. The displacement component 38 can displace a downwardly hanging, flexible suspension means 17 vertically, i.e. pull it up or let it down. A carrier component 3 having a mechatronic installation component 5, which will be discussed in greater detail in connection with FIG. 2, is suspended from the suspension means 17.

(15) The rail 32, the roller arrangement 36 and the horizontal drive (not shown) together form a horizontal shifting means 33. The holding rods 30, the rail 32, the roller arrangement 36, the horizontal drive (not shown), the single displacement component 38 and the suspension means 17 together form a displacement system 34. The platforms 22, 28, the displacement system 34 and the carrier component 3 with all the parts arranged thereon together form a mounting device 40 for carrying out an installation process in a vertically extending elevator shaft of an elevator system.

(16) By means of the displacement component 38 and the suspension means 17, the carrier component 3 can be displaced in the first vertical car track 12, as shown in FIG. 1a. It can be fixed at different heights and can at least semi-automatically perform mounting steps as part of an installation process. For example, holes can be drilled in the shaft walls of the elevator shaft 10 and tie bolts can be inserted into the drilled holes. The carrier component 3 and the components arranged thereon are designed in particular as described in WO 2017/016783 A1.

(17) In order to carry out an installation process in the elevator shaft 10, the mounting device 40 is thus first introduced into the elevator shaft 10. In this process, the carrier component 3 is introduced into the first vertical car track 12 as shown in FIG. 1a. All of the mounting steps to be performed by the mounting device 40 in the first vertical car track 12 are then performed. For this purpose, the carrier component 3 is displaced vertically to the necessary heights by means of the displacement component 38. After completing the mounting steps within the first vertical car track 12, the carrier component 3 is displaced horizontally into the second vertical car track 14. For this purpose, the roller arrangement 36 is shifted by means of the horizontal drive along the rail 32 in the direction of the second vertical car track 14 and thus in the shift direction D. The displacement component 38, the suspension means 17 and the carrier component 3 with all the components arranged thereon are also shifted or displaced together with the roller arrangement 36 in the direction of the second vertical car track 14.

(18) FIG. 1b shows an intermediate position in which the roller arrangement 36 and the parts suspended therefrom are arranged between the first vertical car track 12 and the second vertical car track 14. FIG. 1c shows the state after completion of the described horizontal displacement. The carrier component 3 is now arranged in the second vertical car track 14. After the horizontal displacement, all of the mounting steps to be performed by the mounting device 40 in the second vertical car track 14 are performed. For this purpose, the carrier component 3 is again displaced vertically to the necessary heights by means of the displacement component 38.

(19) The elevator shaft can also have more than two vertical car tracks, for example four or six. In this case, the horizontal shifting means is designed such that the carrier component can be displaced horizontally into the two outermost vertical car tracks. The carrier component can thus carry out mounting steps in all vertical car tracks.

(20) FIG. 2 shows the carrier component 3 with the parts arranged thereon in an enlarged and more detailed view compared to FIGS. 1a to 1c. The carrier component 3 is designed as a cage-like frame in which a plurality of horizontally and vertically extending beams form a mechanically loadable structure. The dimensioning of the beams and any struts provided is designed such that the carrier component 3 can withstand forces that can occur during various mounting steps carried out by the installation component 5 as part of an installation process in the elevator shaft 10.

(21) Retaining cables 27 which can be connected to the suspension means 17 are attached to the top of the cage-like carrier component 3. By displacing the suspension means 17 within the elevator shaft 10, i.e. for example by winding up or unwinding the flexible suspension means 17 onto or from the displacement component 38, the carrier component 3 can thus be moved vertically so as to be suspended within the elevator shaft 10.

(22) Guide components, for example in the form of support rollers 25, can also be provided on the carrier component 3, with the aid of which the carrier component 3 can be guided along one or more of the shaft walls 18 of the elevator shaft 10 during a displacement within the elevator shaft 10. In order to allow rolling of the carrier component 3 in the elevator shaft 10 both in the case of vertical and horizontal displacement, the support rollers 25 are designed to be pivotable about an axis perpendicular to the relevant shaft wall 18.

(23) A fixing component 19 is provided on the side of the carrier component 3. In the example shown, the fixing component 19 is formed with an elongate beam extending in the vertical direction, which beam can be displaced in the horizontal direction with respect to the frame of the carrier component 3. For this purpose, the beam can be attached to the carrier component 3 by means of a lockable hydraulic cylinder or a self-locking motor spindle, for example. When the beam of the fixing component 19 is moved away from the frame of the carrier component 3, it moves laterally toward one of the walls 18 of the elevator shaft 10. Alternatively or additionally, rams could be moved backward on the rear side of the carrier component 3 in order to expand the carrier component 3 in the elevator shaft 10. In this way, the carrier component 3 can be secured within the elevator shaft 10 and the carrier component 3 can thus be fixed within the elevator shaft 10 in the lateral direction while a mounting step is being carried out, for example.

(24) In the embodiment shown, the mechatronic installation component 5 is implemented by means of an industrial robot 7. It should be noted, however, that the mechatronic installation component 5 can also be implemented in other ways, for example with differently designed actuators, manipulators, effectors, etc. In particular, the installation component could have mechatronics or robotics specially adapted for use in an installation process within an elevator shaft 10 of an elevator system.

(25) In the example shown, the industrial robot 7 is equipped with a plurality of robot arms that are pivotable about pivot axes. For example, the industrial robot can have at least six degrees of freedom, i.e. a mounting tool 9 guided by the industrial robot 7 can be moved with six degrees of freedom, i.e. with three rotational degrees of freedom and three translational degrees of freedom, for example. The industrial robot can be designed as a vertical buckling arm robot, a horizontal buckling arm robot, a SCARA robot or a Cartesian robot, or as a portal robot, for example.

(26) The free end 8 of the robot can be coupled to various mounting tools 9. The mounting tools 9 can differ with regard to their design and their intended use. The mounting tools 9 can be held on the carrier component 3 such that the free end 8 of the industrial robot 7 can be brought toward them and coupled to one of them. For this purpose, the industrial robot 7 can have, for example, a tool changing system which is designed such that it allows at least the handling of a plurality of mounting tools 9 of this kind.

(27) One of the mounting tools 9 may be designed as a drilling tool, similar to a drilling machine. By coupling the industrial robot 7 to such a drilling tool, the installation component 5 can be designed to allow holes to be drilled in an at least semi-automatically controlled manner, for example in one of the shaft walls 18 of the elevator shaft 10. In this case, the drilling tool can for example be moved and handled by the industrial robot 7 such that the drilling tool drills holes with a drill bit at a specified position, for example in the concrete of the wall 18 of the elevator shaft 10, into which holes for example fastening screws or tie bolts can be subsequently screwed in order to fix fastening elements.

(28) A further mounting tool 9 may be designed as a screwing device for at least semi-automatically screwing fastening screws into previously drilled holes in a shaft wall 18 of the elevator shaft 10.

(29) Furthermore, a magazine component 11 can be provided on the carrier component 3. The magazine component 11 can be used to store components 13 to be installed and to provide the installation component 5. In the example shown, the magazine component 11 is arranged in a lower region of the frame of the carrier component 3 and houses various components 13, for example in the form of different profiles which are to be mounted within the elevator shaft 10 on shaft walls 18, for example, in order to be able to fasten guide rails for the elevator system thereto. The magazine component 11 can also store and provide screws or tie bolts that can be screwed or inserted into prefabricated holes in the wall 18 by means of the installation component 5.

(30) In order to be able to position the carrier component 3 precisely within the elevator shaft 10, a positioning component 21 can also be provided. The positioning component 21 can, for example, be permanently mounted on the carrier component 3 and can thus be moved along with the carrier component 3 within the elevator shaft 3 when the component is displaced. Alternatively, the positioning component 21 could also be arranged independently of the carrier component 3 at a different position within the elevator shaft 10 and determine a current position of the carrier component 3 from there.

(31) A controller (not shown) of the mounting device can evaluate signals from the positioning component 21 and use these signals to determine an actual positioning relative to a target positioning within the elevator shaft 10. Based on this, the controller can then initially move the carrier component 3 within the elevator shaft 10 to a desired height or allow it to move thereto, for example. Subsequently, taking into account the then determined actual position, the controller can suitably control the installation component 5, for example in order to drill holes at desired locations within the elevator shaft 10, to screw in screws and/or ultimately to mount components 13.

(32) FIGS. 3a to 3c show a mounting device 140 that is an alternative to the mounting device 40 from FIGS. 1a to 1c. The elevator shaft 10 and the carrier component 3 with all the parts arranged thereon are unchanged, and so the following mainly deals with the differences in the displacement systems.

(33) The displacement system 134 of the mounting device 140 according to FIGS. 3a to 3c has a first displacement component 138 in the form of a winch with a first suspension means 117 and a second displacement component 139 in the form of a winch with a second suspension means 115. Both suspension means 115, 117 are connected to the carrier component 3. The carrier component 3 can therefore be suspended on both suspension means 115, 117.

(34) The first displacement component 138 is fixed to a first suspension point 141 of a first elongate carrier 142 which is arranged at the top of the first vertical car track 12 and is supported at its lower end 144 on a threshold 146 of a first door opening 148 of the elevator shaft 10. The threshold 146 can be considered to be part of the shaft wall 18. An upper end 150 of the first carrier 142 leans against a shaft wall 18 opposite the first door opening 148 and is thus supported on this shaft wall 18. The carrier can be designed, for example, like an installation means according to WO 2019/052970 A1 or U.S. Pat. No. 8,646,224 B2. The second displacement component 139 is arranged in the second vertical car track 14 at a second suspension point 143 of a second elongate carrier 152. The second carrier 152 is constructed identically to the first carrier 142 and is arranged analogously thereto between a second door opening 149 and the opposite shaft wall 18. The second suspension point 143 is thus offset in the shift direction D with respect to the first suspension point 141.

(35) In the state shown in FIG. 3a, the carrier component 3 is suspended exclusively on the first suspension means 117; the second suspension means 115 does not exert any significant force on the carrier component 3. The carrier component 3 can thus be displaced vertically in the first vertical car track 12 of the elevator shaft 10 by displacing the first suspension means 117. If the carrier component 3 is to be displaced further downward from the position shown in FIG. 3a, the second suspension means 115 simply has to be slackened accordingly, that is to say unwound from the second displacement component 139. In this way, as described in connection with FIG. 1a, the necessary mounting steps can be performed in the first vertical car track 12.

(36) After completing the mounting steps in the first vertical car track 12, the carrier component 3 is also displaced horizontally into the second vertical car track 14. For this purpose, it is pulled in the direction of the second vertical car track 14 by means of the second suspension means 115. If the first suspension means 117 is neither shortened nor lengthened, the carrier component 3 moves in an arc around the first displacement component 138. The first displacement component 138 can also be controlled in such a way that it shortens the first suspension means 117 to match the shortening of the second suspension means 115 so as to result in only a horizontal displacement of the carrier component 3.

(37) A corresponding intermediate position of the carrier component 3 between the two vertical car tracks 12, 14 is shown in FIG. 3b. The horizontal displacement is ended when the carrier component 3 is arranged vertically below the second displacement component 139. This state is shown in FIG. 3c. The carrier component 3 is then suspended exclusively on the second suspension means 115; the first suspension means 117 does not exert any significant force on the carrier component 3. The carrier component 3 can thus be displaced vertically in the second vertical car track 14 of the elevator shaft 10 by displacing the second suspension means 115. In this way, as described in connection with FIG. 1c, the necessary mounting steps can be performed in the second vertical car track 14.

(38) The displacement components 138, 139 and the suspension means 115, 117 thus together form a displacement system 134 which can displace the carrier component 3 both vertically within the two vertical car tracks 12, 14, and thus within the elevator shaft 10, and horizontally in the shift direction D, i.e. between the two vertical car tracks 12, 14.

(39) FIG. 4a shows a state in which all the mounting steps to be carried out in the vertical car tracks 12, 14 of the first vertical section 20 of the elevator shaft 10 have been completed. The mounting is now to be continued in a second vertical section 60 of the elevator shaft 10 which is arranged above the first vertical section 20 and is constructed identically. For this purpose, the entire mounting device 140 is displaced from the first vertical section 20 into the second vertical section 60 with the aid of a construction crane (not shown). After the displacement has been completed, mounting steps can be performed in the two vertical car tracks 12, 14 of the second vertical section 60 in an analogous manner. In particular, a start is made in the second vertical car track 14 and the mounting is then continued in the first vertical car track 12.

(40) Analogously thereto, the mounting device 40 can also be displaced from a first vertical section into a second vertical section of the elevator shaft which is arranged above the first vertical section.

(41) It is of course possible that a horizontal shifting means 33 according to FIGS. 1a to 1c can also be held by carriers 142, 152 according to FIGS. 3a to 3c and that the displacement components 138, 139 according to FIGS. 3a to 3c can also be fixed on platforms 22, 28 according to FIGS. 1a to 1c.

(42) Finally, it should be noted that terms such as comprising, having, etc. do not preclude other elements or steps, and terms such as a or an do not preclude a plurality. Furthermore, it should be noted that features or steps that have been described with reference to one of the above embodiments may also be used in combination with other features or steps of other embodiments described above.

(43) In accordance with the provisions of the patent statutes, the present invention has been described in what is considered to represent its preferred embodiment. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
