Description

The invention relates to a mounting device for carrying out an installation process in an elevator shaft of an elevator system according to the preamble of claim 1 and a method for carrying out an installation process in an elevator shaft of an elevator system according to claim 7.

An installation of an elevator system in a building and in particular an installation of components of the elevator system within an elevator shaft can cause a lot of effort and/or high costs, since a large number of components have to be mounted at different positions within the elevator shaft. To do this, for example, holes must be drilled at certain points in shaft walls and so-called anchor bolts must be inserted into the drilled holes.

The WO 2019/068469 A1 describes a device by means of which a lifting height of an elevator system can be increased by raising a drive platform.

The WO 2018/234351 A1 describes a system that enables easy access to an elevator shaft for a maintenance technician to carry out maintenance work and/or to evacuate damaged elevator cars.

The WO 2017/016783 A1 describes a mounting device for carrying out an installation process in a vertical elevator shaft of an elevator system. The assembly device has a carrier component, a mechatronic installation component in the form of an industrial robot and a displacement system in the form of a combination of a displacement component and a bendable support means. The displacement system is designed to displace the support component vertically within the elevator shaft. The installation component is held on the carrier component and is designed to carry out an assembly step as part of the installation process at least partially automatically. With the use of such a mounting device, the The described installation of components in the elevator shaft can be carried out with less work and less money compared to a purely manual installation by one or more fitters.

In contrast, it is in particular the object of the invention to propose an assembly device and a method for carrying out an installation process in an elevator shaft of an elevator system, which enable an elevator system to be installed with a particularly low amount of work, time and/or costs. According to the invention, this object is achieved with a mounting device having the features of claim 1 and a method having the features of claim 9.

The exemplary embodiments described relate equally to the assembly device and the method for carrying out an installation process. In other words, features mentioned below, for example with reference to the assembly device, can also be implemented as method steps, and vice versa.

The assembly device according to the invention for carrying out an installation process in a vertical elevator shaft of an elevator system has a support component, a mechatronic installation component and a displacement system. The displacement system is designed to displace the support component vertically within the elevator shaft. The installation component is held on the carrier component and is designed to carry out an assembly step as part of the installation process at least partially automatically. The displacement system is designed and arranged in such a way that it can also displace the carrier component horizontally along a displacement direction within the elevator shaft.

The mentioned horizontal displacement can be combined with a vertical displacement or consist of different sections that at least also include a vertical displacement. So it doesn't have to be exclusively horizontal.

The above-mentioned horizontal displacement of the support component makes it possible that the installation component compared to the mounting device according to WO 2017/016783 A1 can carry out assembly steps in a larger work area within the elevator shaft without the need for a comparatively complex and therefore labor-, time- and cost-intensive relocation of the entire assembly device. The possibility of horizontally displacing the carrier component could also be used to reduce the range of the installation component while maintaining at least the same working area of the assembly device. The installation component and the carrier component could then be compared to a mounting device according to WO 2017/016783 A1 smaller, lighter and also more cost-effective. This would also lead to simple and therefore cost-effective handling of the installation component and the carrier component.

An elevator system has at least one elevator car, by means of which people and/or goods can be transported in a vertical direction in a vertical car track within the elevator shaft. The elevator system can also have more than one vertical car track within the elevator shaft, with at least one elevator car being able to be displaced vertically in each vertical car track. The displacements of the elevator cars in the different vertical car tracks are in particular independent of one another. Such an elevator system is often referred to as a so-called elevator group. When fully assembled or ready for operation, the vertical car tracks of the elevator shaft are usually separated from one another by steel beams, which are also referred to as so-called “divider beams”. For example, so-called guide rails for guiding the elevator cars and/or counterweights are then attached to the steel supports.

The carrier component can be designed in different ways. For example, the carrier component can be designed as a simple platform, frame, scaffolding, cabin or similar. Dimensions of the carrier component should be selected such that the carrier component can be easily accommodated in the elevator shaft and relocated within this elevator shaft.

The installation component should be mechatronic, that is, interacting have mechanical, electronic and information technology elements or modules. For example, the installation component should have suitable mechanics, for example to be able to handle tools within an assembly step. The tools can, for example, be suitably brought to an assembly position by the mechanics and/or be suitably guided during an assembly step.

Electronic elements or modules of the mechatronic installation component can, for example, serve to appropriately control or control mechanical elements or modules of the installation component. Such electronic elements or modules can therefore serve, for example, as a control for the installation component.

Furthermore, the installation component can have information technology elements or modules with the help of which, for example, it can be derived to which position a tool should be brought and/or how the tool should be operated and/or guided there during an assembly step.

An interaction between the mechanical, electronic and information technology elements or modules should take place in such a way that at least one assembly step can be carried out semi-automatically or fully automatically by the assembly device as part of the installation process.

The assembly device in particular has a control device which controls the assembly device. For example, it controls actuators of the displacement system, such as a controllable winch or an electric motor. It also evaluates measured values from sensors in the assembly device and is in communication with electronic elements and modules in the installation component.

Guide components can also be provided on the carrier component, with the help of which the carrier component can be guided along one or more of the shaft walls of the elevator shaft during displacement within the elevator shaft. The guide components can be used, for example, as support rollers be designed to roll on a shaft wall of the elevator shaft. Depending on the arrangement of the support rollers, one to four support rollers can be provided on the carrier component. In order to enable rolling both when the support component is moved vertically and horizontally in the elevator shaft, the support rollers are designed to be pivotable in particular about an axis perpendicular to the shaft wall in question.

The displacement system in particular has at least one displacement component, for example in the form of a winch or a so-called cable winch. The carrier component is then connected to the at least one displacement component via a bendable suspension element and can be displaced in the elevator shaft by displacing the suspension element. The suspension means can have one or more strands arranged in parallel in the form of ropes, chains or belts. The at least one displacement component is arranged in a stationary manner, in particular above the carrier component, so that the carrier component hangs on the at least one displacement component via the support means. It is also possible for the at least one displacement component to be arranged on the carrier component and for an end of the suspension element opposite the displacement component to be fixed above the carrier component. In this case, the carrier component and the at least one displacement component hang on the suspension element.

With the exception of the displacement system, the assembly device is, for example, corresponding to an assembly device according to WO 2017/016783 A1 executed.

According to the invention, the displacement system has a first displacement component with a first suspension element and a second displacement component with a second suspension element. The carrier component is suspended via the first displacement component and the first suspension means at a first suspension point and via the second displacement component and the second suspension means at a second suspension point, the second suspension point being arranged offset in the direction of displacement relative to the first suspension point. This means that the carrier component can be displaced vertically and horizontally in the direction of displacement by displacing the first suspension element and/or the second suspension element.

This means that a horizontal displacement of the carrier component can be realized easily and therefore cost-effectively.

The suspension points mentioned are in particular arranged in a stationary manner relative to the elevator shaft. A suspension point can be designed, for example, as a hook fixed in a shaft wall of the elevator shaft, as a hook on a platform arranged stationary in the elevator shaft or as a hook on a carrier arranged stationary in the elevator shaft. The displacement components are in particular fixed at their respective suspension point. For example, they can be attached directly to the suspension point or via a piece of suspension means with a particularly constant length at the suspension point. This means that when the carrier component is relocated, the displacement components do not also have to be relocated.

For example, the first displacement component is arranged in an upper region of a first vertical car track and the second displacement component is arranged in an upper region of a second vertical car track. If the carrier component hangs exclusively on the first suspension element, i.e. no significant force acts on the carrier component via the second suspension element, the carrier component is displaced vertically in the first cabin vertical track when the first suspension element is displaced. If the carrier component hangs exclusively on the second suspension element, i.e. no significant force acts on the carrier component via the first suspension element, the carrier component is displaced vertically in the second cabin vertical track when the second suspension element is displaced. If sufficient forces act on the carrier component via both suspension means, the carrier component can also be displaced horizontally. For example, if the carrier component initially only hangs on the first suspension element and then the carrier component is pulled towards the second suspension point via the second suspension element, the carrier component is displaced in an arc around the first suspension point in the direction of the second suspension point. The support component is thus displaced both vertically and horizontally. By coordinated pulling with the second suspension element and slackening of the first suspension element, the carrier component can also be displaced exclusively horizontally.

The arrangement of the two suspension points relative to one another, in particular their horizontal distance from one another, determines the area in which the support component can be moved horizontally. The suspension points are in particular arranged approximately centrally in an upper region of two different vertical cabin tracks. The two cabin vertical tracks can be arranged directly next to one another or one or more cabin vertical tracks can also be arranged between them. The suspension points are arranged in particular on the outermost vertical car tracks of the elevator shaft, so that the carrier component can be displaced horizontally in all vertical car tracks and vertically in all vertical car tracks.

• vertikal in einer im Aufzugschacht verlaufenden ersten Kabinen-Vertikalfahrbahn des Aufzugsystems,
• horizontal von der ersten Kabinen-Vertikalfahrbahn in eine in Verschieberichtung im Aufzugschacht neben der ersten Kabinen-Vertikalfahrbahn verlaufende zweite Kabinen-Vertikalfahrbahn des Aufzugsystems und
• vertikal in der zweiten Kabinen-Vertikalfahrbahn

• vertically in a first vertical car track of the elevator system running in the elevator shaft,
• horizontally from the first car vertical track into a second car vertical track of the elevator system running in the direction of displacement in the elevator shaft next to the first car vertical track and
• vertically in the second cabin vertical track

can shift.

This means that the assembly device can be used to carry out assembly steps in adjacent vertical cabin lanes at least partially automatically without any complex modification work. This means that installations in an elevator shaft of an elevator group can be carried out very quickly and cost-effectively.

The first and second cabin vertical tracks do not necessarily have to be arranged directly next to one another, i.e. adjacent to one another. It is possible for one or more further cabin vertical tracks to be arranged between the first and second cabin vertical tracks.

In an embodiment not covered by the scope of protection of the claims, the displacement system has a horizontal displacement device, only one

Displacement component and a suspension element. The support means is vertically displaceable by means of the displacement component, the support component is connected to the horizontal displacement device via the suspension means and the displacement component, and the displacement component is horizontally displaceable with the support means and support component in the displacement direction along the horizontal displacement device.

This means that a horizontal displacement of the carrier component can be realized easily and therefore cost-effectively.

The horizontal displacement device has in particular a rail, for example in the form of a double-T beam, which is fixed in the elevator shaft above the support component, aligned horizontally in the direction of displacement. The support means or the displacement component is held on the rail and thus suspended via a coupling device, for example a roller arrangement. The coupling device can be moved along the rail via a suitable horizontal drive, for example a combination of an electric motor, a toothed belt and corresponding deflection rollers. Together with the coupling device, the displacement component with the suspension element and the carrier component is then displaced horizontally.

In an embodiment of the invention, the first suspension point is arranged on a first platform, which closes off the first vertical cabin track at the top. The second suspension point is arranged on a second platform, which closes off the second vertical cabin track at the top. The first platform and the second platform are in particular designed as separate platforms. However, it is also possible that they are designed as a single, common platform.

The platforms mentioned serve in particular as protective platforms if the elevator shaft is not closed at the top, i.e. the building above the platform is still being built. In this case, such platforms are necessary to protect against falling objects, so that the suspension points can be arranged on the platforms without much effort.

In addition, in this case, ledges or niches are usually provided in the elevator shaft on which the platforms can be supported easily and safely. For this purpose, the platforms each have at least one, in particular two or four horizontally extendable support beams, by means of which the platforms can be supported in the vertical direction at suitable support points in the form of the mentioned shoulders or niches. It is also possible for support elements to be fixed, in particular screwed, to shaft walls of the elevator shaft before the assembly device is introduced into the elevator shaft, on which the platforms can be supported.

In an embodiment of the invention, the first suspension point is arranged on a first support, which is supported within the first vertical car track on opposite shaft walls of the elevator shaft. The second suspension point is then arranged on a second support, which is supported within the second vertical car track on opposite shaft walls of the elevator shaft.

The elongated supports are arranged, in particular, oriented obliquely upwards in the elevator shaft. A lower end of the carrier is supported, for example, on a threshold of a door opening of the elevator shaft. An upper end leans against a shaft wall opposite the door opening mentioned and is thus supported on this shaft wall. The carrier can, for example, be like an installation device according to WO 2019/052970 A1 or the US 8,646,224 B2 be carried out.

• Einbringen einer erfindungsgemässen Montagevorrichtung in den Aufzugschacht;
• gesteuertes Verlagern Trägerkomponente der Montagevorrichtung innerhalb des Aufzugschachts;
• zumindest teilautomatisches Ausführen eines Montageschrittes im Rahmen des Installationsvorgangs mithilfe der Installationskomponente der Montagevorrichtung.

The above-mentioned task is also achieved with a method for carrying out an installation process in a vertical elevator shaft of an elevator system, which has at least the following steps:

• Introducing an assembly device according to the invention into the elevator shaft;
• controlled displacement of the carrier component of the assembly device within the elevator shaft;
• at least partially automatically carrying out an assembly step as part of the installation process using the installation component of the assembly device.

In an embodiment of the invention, the carrier component of the assembly device is inserted into a first vertical car track of the elevator shaft. After being introduced into the elevator shaft, it is displaced vertically in the first vertical car track and carries out the assembly steps to be carried out within the first vertical car track. After completion of the assembly steps within the first vertical car track, it is shifted horizontally from the first vertical car track into a second vertical car track of the elevator system, which runs in a displacement direction next to the first vertical car track. After completion of the said relocation, it is shifted vertically in the second cabin vertical track and carries out the assembly steps to be carried out within the second cabin vertical track.

This procedure enables the assembly steps necessary in the elevator shaft to be carried out particularly effectively.

In an embodiment of the invention, after completion of the assembly steps within the car vertical tracks of a first vertical section of the elevator shaft, the assembly device is relocated to a second vertical section of the elevator shaft arranged above the first vertical section in order to carry out further assembly steps there at least partially automatically.

The relocation can be carried out, for example, by means of a construction crane, which is already available for the construction of the building containing the elevator shaft.

This procedure can be used advantageously if the elevator shaft is so high that the assembly device cannot be relocated within the entire elevator shaft. It can also be used advantageously in particular if the assembly device is already used in the first vertical section of the elevator shaft when construction is still taking place above the first vertical section.

It is pointed out that some of the possible features and advantages of the invention are described herein with reference to different embodiments of the mounting device according to the invention on the one hand and the inventive Method on the other hand are described. One skilled in the art will recognize that the features may be suitably combined, adapted, transferred or exchanged to achieve further embodiments of the invention.

According to Fig. 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 second vertical car track 14 arranged directly next to the first vertical car track 12. The two cabin vertical tracks 10, 12 are in the Fig. 1a to 1c separated from each other by two dashed lines 16. In the fully assembled state of the elevator system, several steel supports are arranged vertically spaced between the two lines 16, which separate the two vertical car tracks 12, 14 from each other. Guide rails are then attached to the steel beams and to the shaft walls 18 of the elevator shaft 10 opposite the steel beams, along which at least one elevator car per vertical car track 12, 14 is guided during a displacement in the corresponding vertical car track 12, 14.

In the Fig. 1a to 1c a first vertical section 20 of the elevator shaft 10 is shown. Above the first vertical section 20, the elevator shaft 10 is in particular not yet completely finished, but is still under construction. The first cabin vertical 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 is part of a mounting device 40, which is not included in the scope of protection of the claims, for carrying out an installation process in a vertical elevator shaft of an elevator system and protects the first car vertical carriageway 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 towards the shaft walls 18. To introduce the first platform 22 into the elevator shaft 10, the support beams 24 can be retracted inwards under 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 downwards. The other two support beams 24, which are oriented in the direction of the second vertical car track 14, rest on support elements 23 that are fixed in the elevator shaft 10 before the first platform 22 is inserted and are thus supported downwards. The second cabin vertical track 14 becomes Closed at the top by a second platform 28, which is designed analogously to the first platform 22 and is supported downwards analogously to the first platform 22. It is also possible for the two platforms to be implemented as a single, common platform.

A rail 32 is held below the two platforms 22, 28 via two vertically extending support rods 30. A holding rod 30 is fixed to one of the platforms 22, 28. The rail 32 is designed, for example, as a double-T beam and runs horizontally. It runs from the first cabin vertical track 12 into the second cabin vertical track 14 and thus in a displacement direction 9. A coupling device in the form of a roller arrangement 36 is guided in the rail 32, which is displaced on the rail 32 by means of a horizontal drive (not shown) and thus can be moved horizontally between the two cabin vertical tracks 12, 14.

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

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

By means of the displacement component 38 and the support means 17, the carrier component 3 can be as in Fig. 1a shown in the first cabin vertical track 12 are relocated. It can be fixed at different heights and at least carry out assembly steps semi-automatically as part of an installation process. For example, holes can be drilled into the shaft walls of the elevator shaft 10 and anchor bolts can be inserted into the drilled holes. The carrier component 3 and the components arranged on it are in particular as in the WO 2017/016783 A1 carried out as described.

To carry out an installation process in the elevator shaft 10, the assembly device 40 is first introduced into the elevator shaft 10. The carrier component 3 is as in Fig. 1a shown introduced into the first cabin vertical track 12. All assembly steps to be carried out by the assembly device 40 in the first cabin vertical track 12 are then carried out. For this purpose, the carrier component 3 is vertically displaced to the necessary heights by means of the displacement component 38. After completion of the assembly steps within the first cabin vertical track 12, the carrier component 3 is relocated horizontally into the second cabin vertical track 14. For this purpose, the roller arrangement 36 is moved by means of the horizontal drive along the rail 32 in the direction of the second vertical cabin track 14 and thus in the displacement direction 9. Together with the roller arrangement 36, the displacement component 38, the support means 17 and the carrier component 3 with all the components arranged on it are also displaced or displaced in the direction of the second vertical cabin track 14.

In Fig. 1b An intermediate position is shown in which the roller arrangement 36 and the parts hanging on it are arranged between the first vertical cabin track 12 and the second vertical cabin track 14. In Fig. 1c The state is shown after the horizontal displacement described has been completed. The carrier component 3 is now arranged in the second cabin vertical track 14. After the mentioned horizontal displacement, all assembly steps to be carried out by the assembly device 40 in the second cabin vertical track 14 are carried out. For this purpose, the carrier component 3 is again vertically displaced to the necessary heights by means of the displacement component 38.

The elevator shaft can also have more than two vertical car tracks, for example four or six. In this case, the horizontal displacement device is designed so that the carrier component is in the two outermost vertical cabin tracks can be moved horizontally. The carrier component can therefore carry out assembly steps in all vertical cabin carriageways.

Fig. 2 shows the carrier component 3 with the parts arranged on it in a opposite direction Fig. 1a to 1c enlarged and more detailed representation. The support component 3 is designed as a cage-like frame in which several horizontally and vertically extending spars form a mechanically resilient structure. A dimensioning of the spars and any struts provided is designed such that the support component 3 can withstand forces such as those that can occur during various assembly steps carried out by the installation component 5 as part of an installation process in the elevator shaft 10.

Tethers 27 are attached to the top of the cage-like support component 3 and can be connected to the suspension means 17. By displacing the suspension element 17 within the elevator shaft 10, that is, for example, by winding or unwinding the bendable suspension element 17 onto the displacement component 38, the carrier component 3 can be vertically displaced within the elevator shaft 10 while hanging.

Guide components, for example in the form of support rollers 25, can also be provided on the carrier component 3, with the help of which the carrier component 3 can be guided along one or more of the shaft walls 18 of the elevator shaft 10 during displacement within the elevator shaft 10. In order to enable rolling both when the support component 3 is displaced vertically and horizontally in the elevator shaft 10, the support rollers 25 are designed to be pivotable about an axis perpendicular to the shaft wall 18 in question

A fixing component 19 is provided on the side of the carrier component 3. In the example shown, the fixing component 19 is designed with an elongated spar running in the vertical direction, which can be displaced in the horizontal direction with respect to the frame of the carrier component 3. For this purpose, the spar can be attached to the carrier component 3, for example via a lockable hydraulic cylinder or a self-locking motor spindle. When the spar of the fixing component 19 is displaced away from the frame of the carrier component 3, it moves laterally towards one of the shaft walls 18 of the elevator shaft 10.

Alternatively or additionally, 3 stamps could be moved backwards on the back of the carrier component in order to spread the carrier component 3 in the elevator shaft 10. In this way, the carrier component 3 can be caulked within the elevator shaft 10 and thus, for example, fix the carrier component 3 within the elevator shaft 10 in the lateral direction while carrying out an assembly step.

In the embodiment shown, the mechatronic installation component 5 is carried out using an industrial robot 7. It should be noted that the mechatronic installation component 5 can, however, also be implemented in another way, for example with differently designed actuators, manipulators, effectors, etc. In particular, the installation component could be mechatronics specially adapted for use in an installation process within an elevator shaft 10 of an elevator system or robotics.

In the example shown, the industrial robot 7 is equipped with several robot arms that can be pivoted about pivot axes. For example, the industrial robot can have at least six degrees of freedom, that is, an assembly tool 9 guided by the industrial robot 7 can be moved with six degrees of freedom, that is, for example, with three rotational degrees of freedom and three translational degrees of freedom. For example, the industrial robot can be designed as a vertical articulated arm robot, as a horizontal articulated arm robot or as a SCARA robot or as a Cartesian robot or gantry robot.

The robot can be coupled to various assembly tools 9 at its cantilevered end 8. The assembly tools 9 can differ in terms of their design and intended use. The assembly tools 9 can be held on the carrier component 3 in such a way that the cantilevered end 8 of the industrial robot 7 can be moved towards them and coupled to one of them. For this purpose, the industrial robot 7 can, for example, have a tool changing system that is designed in such a way that it enables at least several such assembly tools 9 to be handled.

One of the assembly tools 9 can be used as a drilling tool, similar to a drilling machine. be designed. By coupling the industrial robot 7 with such a drilling tool, the installation component 5 can be designed to enable at least partially automated drilling of holes, for example in one of the shaft walls 18 of the elevator shaft 10. The drilling tool can be moved and handled by the industrial robot 7, for example, in such a way that the drilling tool uses a drill to drill holes, for example in the concrete of the wall 18 of the elevator shaft 10, at a designated position, into which later, for example, fastening screws or anchor bolts for fixing fastening elements are inserted can.

Another assembly tool 9 can be designed as a screwing device in order to screw screws into previously drilled holes in a shaft wall 18 of the elevator shaft 10 at least partially automatically.

A magazine component 11 can also be provided on the carrier component 3. The magazine component 11 can serve to store components 13 to be installed and to provide them to 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 on shaft walls 18 within the elevator shaft 10, for example in order to attach guide rails for the elevator system to it can. Screws or anchor bolts can also be stored and provided in the magazine component 11, which can be screwed or inserted into prefabricated holes in the wall 18 using the installation component 5.

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 thus be moved within the elevator shaft 3 when the carrier component 3 is moved. Alternatively, the positioning component 21 could also be arranged at a different position within the elevator shaft 10 independently of the carrier component 3 and from there determine a current position of the carrier component 3.

A control of the assembly device, not shown, 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 control can then, for example, first move or allow the carrier component 3 to move to a desired height within the elevator shaft 10. Subsequently, the control can appropriately control the installation component 5, taking into account the actual position then determined, for example to drill holes at desired locations within the elevator shaft 10, screw in screws and/or ultimately mount components 13.

In the Fig. 3a to 3c is one for the assembly device 40 from the Fig. 1a to 1c alternative mounting device 140 shown. The elevator shaft 10 and the carrier component 3 with all the parts arranged therein are unchanged, so that the differences in the displacement systems will be discussed below.

The displacement system 134 of the mounting device 140 according to Fig. 3a to 3c has a first displacement component 138 in the form of a winch with a first suspension element 117 and a second displacement component 139 in the form of a winch with a second suspension element 115. Both suspension elements 115, 117 are connected to the support component 3. The carrier component 3 can therefore hang on both suspension elements 115, 117.

The first displacement component 138 is fixed to a first suspension point 141 of a first elongated support 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 viewed as 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, for example, be like an installation device according to WO 2019/052970 A1 or the US 8,646,224 B2 be carried out. The second displacement component 139 is arranged in the second cabin vertical track 14 at a second suspension point 143 of a second elongated carrier 152. The second carrier 152 is constructed identically to the first carrier 142 and is arranged analogously to this between a second door opening 149 and the opposite shaft wall 18. This is the second suspension point 143 is arranged offset in the displacement direction 9 relative to the first suspension point 141.

Im in Fig. 3a In the state shown, the carrier component 3 hangs exclusively on the first suspension element 117, the second suspension element 115 does not exert any significant force on the carrier component 3. This allows the carrier component 3 to be displaced vertically in the first vertical car track 12 of the elevator shaft 10 by displacing the first suspension element 117. If the carrier component 3 starts from the in the Fig. 3a If the position shown is to be shifted further downwards, only the second suspension element 115 has to be correspondingly relaxed, i.e. unwound by the second displacement component 139. This means that in connection with the Fig. 1a described, the necessary assembly steps are carried out in the first cabin vertical track 12.

After completion of the assembly steps in the first cabin vertical track 12, the carrier component 3 is also relocated horizontally into the second cabin vertical track 14. To do this, it is pulled towards the second vertical cabin track 14 by means of the second suspension element 115. If the first suspension element 117 is neither shortened nor lengthened, the carrier component 3 moves along a circular 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 element 117 to match the shortening of the second suspension element 115 that only a horizontal displacement of the carrier component 3 results.

A corresponding intermediate position of the carrier component 3 between the two vertical cabin tracks 12, 14 is in the Fig. 3b shown. The horizontal displacement is completed when the carrier component 3 is arranged vertically below the second displacement component 139. This condition is in Fig. 3c shown. The carrier component 3 then hangs exclusively on the second suspension element 115; the first suspension element 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 element 115. This means that in connection with the Fig. 1c described, the necessary assembly steps are carried out in the second cabin vertical track 14 become.

The displacement components 138, 139 and the support means 115, 117 together form a displacement system 134, which moves the carrier component 3 both vertically within the two vertical car tracks 12, 14 and thus within the elevator shaft 10, and horizontally along the displacement direction 9, i.e. between the two cabin vertical tracks 12, 14 can shift.

Fig. 4a shows a state in which all assembly steps to be carried out in the car vertical tracks 12, 14 of the first vertical section 20 of the elevator shaft 10 have been completed. The assembly should now be continued in a second vertical section 60 of the elevator shaft 10 which is arranged above the first vertical section 20 and has an identical structure. For this purpose, the complete assembly device 140 is moved from the first vertical section 20 to the second vertical section 60 with the aid of a construction crane, not shown. After the relocation has been completed, assembly steps can be carried out in an analogous manner in the two cabin vertical tracks 12, 14 of the second vertical section 60. In particular, the installation begins in the second vertical cabin track 14 and then continues assembly in the first vertical cabin track 12.

Analogously, the mounting device 40 can also be moved from a first vertical section into a second vertical section of the elevator shaft arranged above the first vertical section.

It is of course possible for a horizontal displacement device 33 according to Fig. 1a to 1c also from carriers 142, 152 according to Fig. 3a to 3c can be held and that the displacement components 138, 139 according to Fig. 3a to 3c also on platforms 22, 28 according to Fig. 1a to 1c can be fixed.

Furthermore, it should be noted that features or steps that have been described with reference to one of the above exemplary embodiments can also be used in combination with other features or steps from others above described embodiments can be used.
