Description

[0001] Elevator component holding system and method for fixing an elevator component holding system to a shaft wall of an elevator shaft

[0002] The invention relates to an elevator component holding system for fixing to a shaft wall of an elevator shaft according to the preamble of claim 1 and a method for fixing an elevator component holding system to a shaft wall of an elevator shaft according to the preamble of claim 11.

[0003] WO 2017 / 016781 A1 describes an elevator component holding system for fixing to the shaft wall of an elevator shaft and a method for fixing such a system to the shaft wall of an elevator shaft. The elevator component holding system comprises a component holder in the form of a rail bracket base. This base has a contact element designed to rest against the shaft wall when the component holding system is fixed to the shaft wall. This contact element features a specially shaped recess, which distinguishes the rail bracket base from commonly used rail bracket bases that are available on the market in various versions at relatively low cost. The elevator component holding system also includes a screw with a screw head or an anchor bolt with a nut.

[0004] The elevator component holding system can assume a separated state and an attached state. In the separated state, the elevator component holder and the screw or anchor bolt are separate from each other. In the attached state, the screw or anchor bolt protrudes through the recess of the mounting component. A lower portion of the recess in the mounting component of the rail bracket lower section is designed so that the screw head or the nut screwed onto the anchor bolt can pass through this portion of the recess when the component is attached. An upper portion of the recess is designed so that the screw head or the nut screwed onto the anchor bolt cannot pass through it. The rail bracket lower section can thus be attached to the screw or anchor bolt and then placed onto it.The described design of the upper part of the recess prevents the lower rail bracket section from being removed from the screw or anchor bolt without being actively lifted. This elevator component holding system allows the lower rail bracket section to be attached to the screw or anchor bolt using an effector or tool of a mechatronic installation component, such as a gripper on an industrial robot. Once attached, the lower rail bracket section is secured against falling. This allows the aforementioned mechatronic installation component to replace the gripper with a different effector, for example, for tightening the screw or the nut, after the lower rail bracket section has been attached and is thus securely held against the shaft wall.

[0005] The described special design, compared to a standard design of the recess in the mounting part of the rail bracket lower section, results in the rail bracket lower section being comparatively expensive compared to standard rail brackets.

[0006] In contrast, the object of the invention is, in particular, to propose a cost-effective elevator component holding system for fixing an elevator component holding system to a shaft wall of an elevator shaft, which can be easily and securely fixed to a shaft wall of an elevator shaft using a suitable method. According to the invention, this object is achieved with an elevator component holding system having the features of claim 1 and a method having the features of claim 11.

[0007] The elevator component holding system according to the invention, for fixing to the shaft wall of an elevator shaft, comprises an elevator component holder with a mounting element. The mounting element is designed to rest against the shaft wall when the elevator component holding system is fixed to the shaft wall and has a recess. The elevator component holding system also has an anchor bolt, which is designed to be driven into a hole in the shaft wall. The elevator component holding system can assume a separated state and an attached state. In the separated state, the elevator component holder and the anchor bolt are separated from each other, and in the attached state, the anchor bolt protrudes through the recess of the mounting element.According to the invention, the elevator component holding system has a locking element which is designed and arranged in such a way that the locking element allows the elevator component holding system to change from the separated state to the attached state against a resistance applied by the locking element and, with the anchor bolt driven into the hole in the shaft wall, holds the elevator component holding system in the attached state after a change from the separated state to the attached state.

[0008] This advantageously eliminates the need for a specially designed recess in the mounting part of the elevator component holder, allowing the use of a standard elevator component holder, such as a rail bracket base. This enables a comparatively cost-effective implementation of the inventive elevator component holding system. Nevertheless, the inclusion of a locking element prevents the elevator component holder from slipping off the anchor bolt and falling into the elevator shaft after being attached. This locking element can be designed to be cost-effective. Falling parts pose a significant hazard to personnel working in the elevator shaft. Holding the elevator component holder in place with the locking element, and thus preventing it from falling, ensures safe installation in the elevator shaft.

[0009] The following described embodiments and exemplary embodiments of the invention relate equally to the elevator component holding system and the method for fixing the elevator component holding system to a shaft wall. In other words, features mentioned below, for example, with reference to the elevator component holding system, can also be implemented as method steps, and vice versa. The elevator shaft and the elevator components fixed and thus installed in the elevator shaft are part of an elevator system.

[0010] In the preceding and following text, directional terms such as top, bottom, and side, or vertical and horizontal, refer to the orientation of the respective component, for example, an elevator component holder, specifically a rail bracket lower section, in an operating state of the elevator system. The operating state of the elevator system is understood to be the state after completion of installation and commissioning. In this operating state, people and / or goods can be transported in an elevator car between floors of the building housing the elevator system.

[0011] The elevator component holder serves to secure an elevator component to the shaft wall. It is primarily designed as a lower rail bracket to which an upper rail bracket can be attached, particularly by screwing. A guide rail or a section of guide rail can be attached to the upper rail bracket to guide a cabin or counterweight during movement within the elevator shaft. Other elevator components can also be secured to the shaft wall using the elevator component holder.

[0012] The term "fixing" the elevator component holding system to the shaft wall means that the entire system is securely mounted to the shaft wall, preventing any movement. After fixing, no part of the system can be displaced relative to the shaft wall. The component holder is then pressed against the shaft wall by a nut screwed onto the anchor bolt, ensuring it rests against the wall. Specifically, the nut is only screwed on after the component holder has been driven into and attached to the anchor bolt. When the component holder is being attached to the anchor bolt—that is, when the system is being moved from its detached state to its attached state—the nut is not yet screwed onto the anchor bolt.

[0013] The component has a predominantly cuboid shape. A fastening element is attached to the component, which may, for example, form a right angle with the component and thus, when the elevator component holding system is fixed, projects vertically from the shaft wall into the elevator shaft. The fastening element also has one or more recesses for screwing it to another component, such as a rail bracket top.

[0014] The elevator parts holder is designed as a single piece. It consists of only one component and, in particular, of a single material. This allows for a particularly simple and therefore cost-effective design. The elevator parts holder is, for example, made from a 2 to 8 mm thick sheet of metal, which is bent into the desired shape. The outer contour and the aforementioned recess can be achieved, for example, by punching before bending.

[0015] The recess in the mounting component is designed, in particular, as a round through-hole or an elongated hole. The diameter of the round through-hole or the width of the elongated hole is slightly larger than the outer diameter of the anchor bolt, especially the section of the anchor bolt protruding from the shaft wall after it has been driven into a hole in the shaft wall. The mounting component of the elevator component holder may also have more than one recess, specifically two of the recesses described above. The recesses may be of the same or different designs. For example, a round through-hole may be combined with an elongated hole.

[0016] The anchor bolt has a primarily cylindrical shape with two sections. After the anchor bolt is driven into a hole in the shaft wall, the first section is positioned within the hole. A second section protrudes from the hole and thus from the shaft wall into the elevator shaft. This second section has an external thread onto which a nut can be screwed. Anchor bolts, also known as screw anchors, are available in various designs on the market.

[0017] The elevator component holding system is in its attached state, or is brought from its separated to the attached state, particularly when the anchor bolt has already been driven into the hole in the shaft wall. The driving of the anchor bolt into the hole in the shaft wall thus occurs particularly when the elevator component holding system is separated. The locking element is therefore located, particularly in the area of ​​the second section of the anchor bolt, when the elevator component holding system is attached.

[0018] When the elevator component holding system changes from the separated state to the attached state, the component holder is attached to the anchor bolt. This requires a force to overcome the resistance exerted by the locking element on the component holder in the direction of the shaft wall, i.e., in the direction of the first section of the anchor bolt. This direction, from the second section of the anchor bolt towards the first section, is called the attachment direction. The attachment direction thus runs from one end of the anchor bolt towards the end opposite the head. The head of the anchor bolt is understood to be the end onto which the nut is screwed. If the anchor bolt is driven into the hole in the shaft wall, the driving direction runs from the head, and thus from the second section of the anchor bolt, towards the shaft wall.The resistance results primarily from friction between the locking element and the anchor bolt, or between the locking element and the mounting surface of the elevator component holder. The locking element is, for example, elastically designed. This allows the locking element to deform when the elevator component holder is attached to the anchor bolt and subsequently return almost entirely to its original state. The locking element can be made of metal or plastic, for example.

[0019] The locking element secures the elevator component holder system in the attached position after it has been switched from the separated to the attached position. This means that the elevator component holder cannot slip off the anchor bolt or be removed from it on its own, i.e., not without a sufficiently strong external force acting against the direction of attachment. This ensures that the elevator component holder is positioned on the shaft wall in such a way that it can remain in this position for a certain period of time without the risk of falling. Movement of the elevator component holder along the anchor bolt towards the shaft wall is limited by the shaft wall, and movement of the elevator component holder along the anchor bolt away from the shaft wall is prevented and / or limited by the locking element.

[0020] The locking element is firmly connected to the elevator component holder or the anchor bolt, particularly when the elevator component holding system is detached. Thus, the locking element is firmly connected to the elevator component holder or the anchor bolt, particularly when the elevator component holding system is detached and when attached. The locking element is designed such that, when the elevator component holding system is attached, frictional friction between the locking element and the anchor bolt or between the locking element and the mounting part holds the elevator component holder in its position. It is also possible for a positive-locking connection to exist between the locking element and the anchor bolt or between the locking element and the mounting part, which holds the elevator component holder in its position.

[0021] In one embodiment of the invention, the elevator component holder includes the locking element, wherein the recess of the mounting part at least indirectly provides a through-opening for the anchor bolt, and the locking element is designed and arranged on the mounting part such that the through-opening has a smaller cross-section than the recess of the mounting part. The locking element is thus either an integral part of the elevator component holder or is firmly connected to the elevator component holder, for example, by gluing or welding. A force-fit or form-fit connection between the locking element and the elevator component holder is also possible.

[0022] The term "indirect specification of the passage opening by the recess of the system component" here means that either a part of the edge of the recess of the system component forms a part of the edge of the passage opening, or that the recess of the system component limits the maximum extent of the passage opening and the passage opening is specified by the locking element.

[0023] The locking element, in particular, ensures that the cross-section of the aforementioned through-hole is designed such that the second section of the anchor bolt cannot be passed through the through-hole without contacting the locking element. The diameter of the through-hole is, in particular, slightly smaller than the outer diameter of the second section of the anchor bolt.

[0024] In one embodiment of the invention, the locking element of the elevator component holder has a recess which is arranged overlapping with the recess of the mounting part. This allows the locking element to apply a uniform resistance across the circumference of the second section of the anchor bolt when the elevator component holder is attached to the anchor bolt. This enables uniform attachment without tilting of the elevator component holder relative to the anchor bolt.

[0025] It is not absolutely necessary for the locking element of the elevator component holder to have a recess. For example, it is also possible for the locking element to be designed and positioned so that it projects into the recess of the component from the outside, thus reducing the cross-section of the recess. The locking element can be designed, for example, as a tab made of metal or plastic.

[0026] In one embodiment of the invention, the recess of the locking element of the elevator component holder has a smaller cross-section than the recess of the mounting element. It is also possible for the two cross-sections to be the same size or for the size ratio of the cross-sections to be reversed. In both of these cases, the smaller cross-section of the through-opening compared to the recess of the mounting element is achieved by arranging the mounting element and the locking element offset transversely to the longitudinal direction of the anchor bolt.

[0027] In this embodiment of the invention, the mounting part and the locking element of the elevator component holder are arranged one behind the other with respect to the longitudinal axis of the anchor bolt. The anchor bolt thus projects successively through the recess of the mounting part and through the recess of the locking element. The locking element is, in particular, arranged on the side of the mounting part facing away from the shaft wall. In these cases, the locking element can be designed, in particular, as a component that is readily available on the market at a relatively low cost, for example, in the form of a clamping ring, a locking washer, or an internally toothed toothed disc.

[0028] In the arrangement described in the previous paragraph, the locking element can be supported in relation to the shaft wall, particularly when the elevator component holder is attached to the anchor bolt, in the direction of the installation element, i.e., along the longitudinal direction of the anchor bolt towards the shaft wall. This ensures that the locking element is attached to the anchor bolt together with the elevator component holder and can perform the locking function described above after attachment. If the attachment is automated using a mechatronic installation component, the effector used can have a correspondingly designed and positioned support arm. This support eliminates the need for a particularly robust and therefore complex connection between the elevator component holder, especially the installation element, and the locking element.The resistance force exerted when attaching the locking element can thus be at least partially absorbed by the aforementioned support, for example, the support arm. However, it is also possible that the connection between the locking element and the elevator component holder is so robust, e.g., through a welded joint, that no support for the locking element is necessary during attachment.

[0029] In this embodiment of the invention, the recess for the locking element of the elevator component holder is formed by circumferentially arranged tabs. This enables a particularly secure hold of the elevator component holding system in the attached state. The tabs are particularly flexible and, when the elevator component holder and thus the locking element are attached, can be deflected away from the component, temporarily enlarging the opening. This enlargement of the opening allows the component to be attached to the anchor bolt. After attachment, the tabs return to their original position, resulting in a positive-locking and therefore very secure connection between the tabs and the external thread of the anchor bolt.

[0030] The securing element can, for example, have four or more tabs. The tabs can be inclined, particularly when viewed from the outside inwards, away from the mounting surface of the elevator component holder. Specifically, the tabs are inclined away from the shaft wall, so their inner edge is further from the shaft wall than their outer edge. The tabs can also be arranged parallel to the elevator component holder.

[0031] In an embodiment of the invention, the locking element of the elevator component holder is arranged at least partially in the recess of the mounting part. At least a portion of the locking element, which is particularly elastic, then rests against an inner surface of the recess of the mounting part of the elevator component holder. The locking element can then, for example, be designed as a ring or at least have an annular section. The inner diameter of the locking element is, in particular, slightly smaller than the outer diameter of the second section of the anchor bolt, so that friction between the locking element and the anchor bolt must be overcome when the elevator component holder is placed onto the anchor bolt. After placement, the elevator component holding system is held in the mounted state by the static friction between the anchor bolt and the locking element.

[0032] In particular, if the locking element is designed as a ring arranged in the recess of the system component, it can be supported on the anchor bolt when attaching the elevator component holder, as described above.

[0033] In an embodiment of the invention, the locking element of the elevator component holder has a collar extending transversely to the longitudinal axis of the anchor bolt, which is oriented away from the recess of the locking element, in particular radially outwards. The collar can also be described as a shoulder and overlaps the contact part in a direction transverse to the recess of the contact part and thus transverse to the longitudinal direction of the anchor bolt. The collar is arranged, in particular, on the side of the contact part oriented towards the shaft wall and thus prevents the locking element from being pulled or pushed out of the recess of the contact part when it is placed onto the anchor bolt. This eliminates the need for additional support of the locking element when placing the elevator component holder onto the anchor bolt.

[0034] In one embodiment of the invention, the anchor bolt has a locking element, wherein the locking element of the anchor bolt is designed and arranged in a locking element area on the anchor bolt such that the anchor bolt has a larger cross-section in the locking element area than outside the locking element area. This allows for a simple and cost-effective implementation of the locking element.

[0035] The locking element of the anchor bolt is made of an elastic material, such as an elastic plastic. The outer diameter of the locking element is slightly larger than the cross-section of the recess in the mounting part of the elevator component holder. When the elevator component holder is placed onto the anchor bolt, the locking element of the anchor bolt is slightly compressed, so that resistance, particularly in the form of friction, must be overcome during insertion. If the mounting part extends beyond the locking element area on the anchor bolt, the locking element expands back to its original size due to its elastic properties, and the elevator component holder cannot, without a sufficiently large external force, overcome the locking element area of ​​the anchor bolt and thus be removed from the anchor bolt.

[0036] The locking element of the anchor bolt is positioned at a distance from the head of the anchor bolt. Specifically, the locking element is positioned far enough from the head of the anchor bolt that a tool or holder used to drive in the anchor bolt does not damage the locking element during the driving process. The locking element of the anchor bolt can, for example, be a threaded sleeve with an internal thread made of elastic plastic. Alternatively, the locking element may not have an internal thread and may, for example, be pressed onto the anchor bolt. When the nut is tightened, the locking element is pressed against the elevator component holder and is thereby destroyed. The locking element of the anchor bolt has barbs on its outer surface, which are oriented and dimensioned so that the elevator component holder can be placed onto the anchor bolt more easily than it can be removed.This allows the elevator component holder to be attached particularly easily and, once attached, ensures it is exceptionally secure. In particular, the elevator component holder cannot be removed from the anchor bolt without destroying the locking mechanism.

[0037] The above-mentioned problem is also solved by a method for fixing an elevator component holding system described above to a shaft wall of an elevator shaft, which comprises at least the following process steps, in particular those carried out in the order mentioned:

[0038] - Drilling a hole in the shaft wall of the elevator shaft,

[0039] - Driving the anchor bolt into the aforementioned hole in the shaft wall,

[0040] - automated gripping of the elevator component holder with a gripper of a mechatronic installation component of an assembly device,

[0041] - Attaching the elevator component holder to the anchor bolt using the mechatronic installation component, so that the anchor bolt protrudes through the recess of the system component, thereby bringing the elevator component holding system from its separated state to its attached state, whereby a resistance of the locking element is overcome during the aforementioned attachment process.

[0042] - Screwing a nut onto the anchor bolt and

[0043] - Tighten the nut, at least until the mounting part of the elevator component holder rests against the shaft wall.

[0044] The process steps are primarily automated by the mechatronic installation component, which typically consists of only one manipulator. In addition to the process steps explicitly executed by the mechatronic installation component, further process steps can also be performed manually by an installer. Besides the aforementioned process steps, additional process steps can be executed before, after, and between them.

[0045] A mechatronic installation component is defined as a component that comprises interacting mechanical, electronic, and information technology elements or modules. For example, the installation component may have suitable mechanics to handle tools within a process step. The mechanics can, for instance, move the tools appropriately to a mounting position and / or guide them appropriately during a process step.

[0046] Alternatively, the installation component itself can also have a suitable mechanism that forms a tool.

[0047] Electronic elements or modules of the mechatronic installation component can, for example, serve to appropriately control or regulate mechanical elements or modules of the installation component. Such electronic elements or modules can thus, for example, serve as a control system for the installation component. Furthermore, the installation component can have information technology elements or modules that, for example, can be used to determine the position to which a tool should be moved and / or how the tool should be operated and / or guided there during a process step.

[0048] The interaction between the mechanical, electronic and information technology elements or modules should take place in such a way that at least one process step can be carried out automatically by the assembly device during the installation process.

[0049] The mechatronic installation component includes, in particular, an industrial robot. An industrial robot can be understood as a universal, usually programmable machine for handling, assembling, and / or processing workpieces and components. Such robots are designed for use in an industrial environment and are currently used, for example, in the industrial production of complex goods in large quantities, such as in automotive manufacturing.

[0050] An industrial robot typically consists of a manipulator, an effector, and a controller. The manipulator can be, for example, a robot arm that can pivot around one or more axes and / or move along one or more directions. The effector can be, for example, a tool, a gripper, or something similar. A gripper can also be considered a tool. The controller is used to control the manipulator and / or the effector appropriately, meaning, for example, to move and / or guide them. Industrial robots are often equipped with various sensors that allow them to gather information about their environment, working conditions, components being processed, and so on. For example, sensors can detect forces, pressures, accelerations, temperatures, etc., in order to subsequently analyze them.After initial programming, an industrial robot is typically capable of performing a work process semi-automatically or fully automatically, meaning largely autonomously. The execution of the work process can be varied within certain limits, for example, depending on sensor information. Furthermore, the control system of an industrial robot can potentially be self-learning.

[0051] An industrial robot, based on the way its components are mechanically and / or electrically designed, and the way these components can be controlled by the robot's control system, can perform various process steps during an installation in an elevator shaft or adapt to different conditions during such a process step. For example, to move the industrial robot to a desired position within the elevator shaft, it is attached to a support structure, which, along with the industrial robot and any other installation components, can be moved to the desired position within the elevator shaft.

[0052] As an alternative to being designed as an industrial robot, the mechatronic installation component can also be configured in other ways. Among other possibilities, mechatronic machines specifically designed for the aforementioned application in a (semi-)automated elevator installation are conceivable, employing, for example, special drills, screwdrivers, feeding components, etc. Linearly movable drilling tools, screwdrivers, and similar components could be used, for instance.

[0053] In this embodiment of the invention, the locking element of the elevator component holder, arranged on the elevator component holder, is supported towards the installation part by a support arm connected to the gripper of the mechatronic installation component when the elevator component holder is attached to the anchor bolt. This ensures that the locking element is attached to the anchor bolt together with the elevator component holder and can perform the locking function described above after attachment.

[0054] The aforementioned support arm has, in particular, a first section that runs parallel to the shaft wall and thus to the contact area of ​​the elevator component holder when the elevator component holder is attached to the anchor bolt, and a second section that runs perpendicular to the shaft wall. The securing element of the elevator component holder is supported by a portion of the first section. The support arm is connected to the aforementioned gripper via the second section.

[0055] In particular, during the support arm's insertion of the elevator component holder onto the anchor bolt, the anchor bolt protrudes through a recess in the support arm, and the elevator component holder's locking element rests against the support arm. This achieves particularly effective support of the locking element.

[0056] The aforementioned recess in the support arm is located on the first section of the support arm. The recess can be adapted to the outer contour of the securing element of the elevator component holder, and thus also be designed as a circular through-hole or an elongated hole. It is also possible that the first section has two adjacent, vertically extending webs, between which the recess of the support arm extends.

[0057] The support arm is designed such that the position of its recess relative to the gripper is adjustable. In particular, as a further step before mounting the elevator part holder onto the anchor bolt, the specified distance to the elevator part holder is adjusted. This allows the gripper and support arm combination to be used with various elevator part holders. This adjustment can be achieved, for example, by changing the length of the first and / or second section of the support arm. The two sections can have parts that are slidable relative to or within each other.

[0058] It is noted that some of the possible features and advantages of the invention are described herein with reference to different embodiments of the elevator component holding system according to the invention, on the one hand, and the method according to the invention, on the other. A person skilled in the art will recognize that the features can be suitably combined, adapted, transferred, or exchanged to arrive at further embodiments of the invention.

[0059] Further advantages, features, and details of the invention will become apparent from the following description of exemplary embodiments and from the drawings, in which identical or functionally equivalent elements are provided with identical reference numerals. The drawings are schematic only and not to scale.

[0068] Figure 1 shows a mounting device 14 arranged in an elevator shaft 10 of an elevator system 12, by means of which elevator component holders in the form of rail bracket lower sections 16 can be fixed to a shaft wall 18 of the elevator shaft 10. The following description focuses exclusively on elevator component holders in the form of rail bracket lower sections. The following explanations also apply accordingly to other elevator component holders by means of which other elevator components can be fixed to a shaft wall of the elevator shaft.

[0069] The elevator shaft 10 extends in a main direction 11, which is vertically oriented in Fig. 1. Guide rails of the elevator system 12, one of which, a guide rail section 15, is shown in Fig. 1, are fixed to the shaft wall 18 via the lower rail brackets 16. The mounting device 14 comprises a support component 20 and a mechatronic installation component 22. The support component 20 is designed as a frame on which the mechatronic installation component 22 is mounted. This frame has dimensions that allow the support component 20 to be moved vertically within the elevator shaft 10, i.e., for example, to be moved to different vertical positions on different floors within a building. In the illustrated example, the mechatronic installation component 22 is designed as an industrial robot 24, which is suspended downwards from the frame of the support component 20.An arm of the industrial robot 24 can be moved relative to the support component 20 and, for example, moved towards the shaft wall 18 of the elevator shaft 10.

[0070] The support component 20 is connected via a steel cable, serving as a load-bearing element 26, to a displacement component 28 in the form of a motor-driven winch, which is mounted at the top of the elevator shaft 10 at a stop 29 on the ceiling of the elevator shaft 10. Using the displacement component 28, the assembly device 14 can be moved within the elevator shaft 10 in the main extension direction 11 of the elevator shaft 10, i.e., vertically over the entire length of the elevator shaft 10.

[0071] The assembly device 14 also has a fixing component 30, by means of which the support component 20 can be fixed within the elevator shaft 10 in a lateral direction, i.e. in a horizontal direction.

[0072] Two reference elements 13 in the form of cords are stretched along the entire length of the elevator shaft 10, aligned along the main direction of extension 11. An installer places the reference elements 13 in the elevator shaft 10, and they serve as a reference for aligning and mounting the guide rails of the elevator system 12.

[0073] Fig. 2 shows an enlarged view of an assembly device 14. The support component 20 is designed as a cage-like frame in which several horizontally and vertically extending beams form a mechanically load-bearing structure. Retaining cables 32 are attached to the top of the cage-like support component 20 and can be connected to the load-bearing element 26.

[0074] In the illustrated embodiment, the mechatronic installation component 22 is designed as an industrial robot 24. In the illustrated example, the industrial robot 24 is equipped with a robot arm with multiple joints. For example, the industrial robot can have at least six degrees of freedom, meaning that an effector in the form of an assembly tool 34, guided by the industrial robot 24, can be moved with six degrees of freedom, 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 robot, a horizontal articulated robot, a SCARA robot, or a Cartesian robot or gantry robot.

[0075] The robot can be coupled to various assembly tools 34 at its cantilevered end. The assembly tools 34 can differ in their design and intended use. The assembly tools 34 can be held on the carrier component 20 in such a way that the cantilevered end of the industrial robot 24 can be moved towards them and coupled to one of them. For this purpose, the industrial robot 24 can, for example, have a tool-changing system designed to enable the handling of at least several such assembly tools 34.

[0076] One of the assembly tools 34 can be designed as a drilling tool, similar to a drill. By coupling the industrial robot 24 with such a drilling tool, the installation component 22 can be configured to enable automated drilling of holes in one of the shaft walls 18 of the elevator shaft 10. The drilling tool can be moved and handled by the industrial robot 24 in such a way that the drilling tool, with a drill bit, drills holes at a designated position in the shaft wall 18 of the elevator shaft 10, into which anchor bolts (see 40 in Fig. 3) are later driven to fix elevator component holders in the form of rail bracket lower sections.

[0077] Another assembly tool 34 is designed as a setting tool for automatically driving anchor bolts into pre-drilled holes in the shaft wall 18. Another assembly tool 34 is designed as a gripper for automatically placing an elevator component holder in the form of a rail bracket lower part 16 onto a pre-driven anchor bolt. Another assembly tool 34 can be designed as a screwdriver for semi-automatically placing and screwing on nuts (see 174 in Fig. 7) onto anchor bolts.

[0078] A magazine component 36 can also be provided on the support component 20. The magazine component 36 can serve to store rail bracket lower parts 16 to be installed and to provide them to the installation component 22. Anchor bolts can also be stored and provided in the magazine component 36, which can be driven into holes in the shaft wall 18 using the installation component 22.

[0079] According to Fig. 3, an elevator component holder in the form of a rail bracket lower part 16 is attached to a shaft wall 18 by an assembly tool 34 in the form of a gripper of the mechatronic installation component 22 from Figs. 1 and 2, onto two anchor bolts 40. In the sectional view of Fig. 3, only one anchor bolt 40 is visible. The anchor bolts 40 were previously driven into holes 42 in the shaft wall 18 by the mechatronic installation component 22 using a setting tool. These holes had been pre-drilled with a drilling tool of the mechatronic installation component 22.

[0080] The anchor bolt 40 shown in Fig. 3 has a first section 44 arranged in the hole 42 in the shaft wall 18 and a second section 46 projecting from the hole 42 into the elevator shaft 10. The second section 46 of the anchor bolt 40 has an external thread 47 onto which a nut (not shown in Fig. 3, see 174 in Fig. 7) can be screwed.

[0081] The lower rail bracket section 16 has a predominantly cuboid-shaped mounting section 48, which rests against the shaft wall 18 when the lower rail bracket section 16 is fully fixed. A fastening section 50 is attached to the mounting section 48, forming a right angle with it and thus projecting perpendicularly from the shaft wall 18 into the elevator shaft 10 when the lower rail bracket section 16 is fixed. The fastening section 50 has recesses (not shown) for bolting it to another component, for example, a upper rail bracket section. The lower rail bracket section 16 is held against the fastening section 50 by the gripper 34.

[0082] The mounting part 48 of the rail bracket lower section 16 has two recesses 52 in the form of circular through holes. It is also possible that at least one of the recesses is designed as an elongated hole. The recesses 50 are designed such that the second section 46 of the anchor bolt 40 fits through the respective recess 50 with a small amount of play. In the case of a circular through hole, the diameter is therefore slightly larger than the outer diameter of the second section of the anchor bolt. In the case of an elongated hole, the width is slightly larger than the outer diameter of the second section of the anchor bolt.

[0083] The lower rail bracket 16 has two locking elements 54 attached to one side of the system component 48 facing away from the shaft wall 18, only one of which is shown in Fig. 3. The system component 48 and the locking elements 54 of the lower rail bracket 16 are thus arranged one behind the other with respect to a longitudinal axis 57 of the anchor bolt 40. The locking elements 54 can, for example, be glued or welded to the system component 48. The locking elements 54 are designed, in particular, as clamping rings made of metal or plastic. According to Fig. 4, they have a round outer contour and a total of four inwardly directed tabs 56 inclined away from the system component 48. The locking elements 54 thus also have a recess 58, which each overlaps with the recesses 52 of the system component 48.The tabs 56 extend so far inwards that the cross-section of the recesses 58 of the locking elements 54 is smaller than the cross-section of the recesses 52 of the system component 48. The recesses 52 of the system component 48 and the recesses 58 of the locking elements 54 thus each define a through-opening whose cross-section is smaller than the cross-section of the respective recess 52 of the system component 48.

[0084] The cross-section of the through-opening is designed to fit the anchor bolt 40 used, such that the second section 46 of the anchor bolt 40 only fits through the through-opening if the tabs 56 of the locking element 54 are pressed outwards, which requires a force. The lower rail bracket 16 can therefore only be placed onto the anchor bolt 40 against the resistance exerted by the locking elements 54 of the lower rail bracket 16. As soon as the lower rail bracket 16 is fully placed onto the anchor bolt 40, the tabs 56 of the locking elements 54 return to their original position and thus rest against the respective anchor bolt 40, or press against it from the outside, thereby creating a positive-locking connection between the tabs 46 and the external thread 47 of the anchor bolt 40.Without applying an external force away from the shaft wall 18, the lower part of the rail bracket 16 cannot move away from the shaft wall 18. Without applying an external force towards the shaft wall 18, the lower part of the rail bracket 16 also cannot move towards the shaft wall 18. The lower part of the rail bracket 16 is therefore held in the position on the anchor bolt 40 by the interaction of the locking element 54 with the anchor bolt 40.

[0085] The elevator component holder in the form of the rail bracket lower part 16, the anchor bolt 40, and one or both locking elements 54 of the rail bracket lower part 16 together form an elevator component holding system 59 for fixing to the shaft wall 18 of the elevator shaft 10. The elevator component holding system 59 can assume a separate state and an attached state. In the separate state, the elevator component holder in the form of the rail bracket lower part 16 and the anchor bolts are separated from each other, and in the attached state shown in Fig. 3, the anchor bolt 40 protrudes through the recess 52 of the mounting part 48 of the elevator component holder in the form of the rail bracket lower part 16.The locking elements 54 are designed and arranged in such a way that they allow the elevator component holding system 59 to change from the separated state to the attached state against a resistance applied by the locking elements 54 and hold the elevator component holding system 59 in the attached state after a change from the separated state to the attached state.

[0086] When the lower rail bracket part 16 is placed onto the anchor bolt in the direction of the shaft wall 18, a force directed away from the shaft wall 18 acts on the locking elements 54 of the lower rail bracket part 16. To prevent the locking elements 54 from detaching from the mounting part 48 during placement on the anchor bolts 40, each locking element 54 is supported by a support arm 60. The support arms 60 are identical, therefore only one support arm 60 will be described in detail. Figure 3 also shows only one support arm 60. The support arm 60 rests against the locking element 54 on the side facing away from the shaft wall 18 to support the locking element 54. The support arm 60 has a recess 62 through which the anchor bolt 40 protrudes during placement. The recess 62 of the support arm 62 can have a shape corresponding to the shape of the locking element 54, as shown in Fig. 5.The recess 62 can thus have a circular cross-section. The support arm 60 can also, as shown in Fig. 6, have two parallel downward-extending webs 64, between which the recess 62 of the support arm 60 extends.

[0087] The support arm 60 has a first section 66 extending upwards parallel to the shaft wall 18 and thus to the mounting part 48 of the rail bracket 16 when the lower rail bracket section 16 is placed on the anchor bolt 40, and a second section 68 extending perpendicular to the shaft wall 18. The recess 62 is located on the first section 66. The support arm 60 is connected to the gripper 34 via the second section 68.

[0088] The support arm 60 is designed such that the position of the recess 62 of the support arm 60 relative to the gripper 34 is adjustable. Before the lower rail bracket 16 is placed onto the anchor bolt 40, the aforementioned distance is adjusted to the lower rail bracket 16. This adjustment is achieved by changing the length of the first section 66 and the second section 68 of the support arm 60. The two sections have, for this purpose, parts that are slidable relative to each other or within each other (not shown in detail).

[0089] As shown in Fig. 7, an alternative locking element 154 of the rail bracket lower part 116 is partially arranged within the recess 152 of the mounting part 148. The locking element 154 consists of an annular part 170 arranged within the recess 152 and a circumferential collar 172 extending transversely to the longitudinal axis 157 of the anchor bolt 140. The outer diameter of the annular part 170 of the locking element 154 is selected such that it must be pressed into the recess 152 of the mounting part 148. Without external force, the annular part 170, and thus the locking element 154, cannot move relative to the mounting part 148 and therefore not to the rail bracket lower part 116. The bundle 172 is oriented away from the recess 152 and overlaps with the attachment part 148 in a direction transverse to the recess 152 of the attachment part 148 and thus transverse to the longitudinal direction 157 of the anchor bolt 140.The collar 172 is located on the side of the system component 148 facing the shaft wall 18 and thus prevents the locking element 154 from being pulled or pushed out of the recess 152 of the system component 148 when it is placed on the anchor bolt 140. Therefore, no support arm is needed for the locking element 154 when the rail bracket lower part 116 is placed on the anchor bolt 140. A nut 140 is already screwed onto the anchor bolt 140. The nut 140 was only screwed on after the rail bracket lower part 116 was placed on the anchor bolt 140.The inner diameter of the annular part 170 of the locking element 154, and thus the diameter of a recess 158 of the locking element 154, is slightly smaller than the outer diameter of the second section 146 of the anchor bolt 140. Therefore, when the lower rail bracket part 16 is placed onto the anchor bolt 140, friction between the locking element 154 and the anchor bolt 154 must be overcome. After placement, static friction acts between the locking element 154 and the anchor bolt 154, which counteracts movement of the locking element 154, and thus of the lower rail bracket part 116, relative to the anchor bolt. The elevator component holding system 159 is thus held in the placed state by the static friction between the anchor bolt 140 and the locking element 154.

[0090] It is also possible that the locking element consists solely of a ring arranged within the recess of the component. The descriptions of the annular part 170 of the locking element 154 apply accordingly to this ring. This ring could then be supported by a support arm, analogous to the locking element 54 shown in Fig. 1.

[0091] In the embodiment of the elevator component holding system 259 according to Fig. 8, the anchor bolt 240 has a locking element 254. The locking element 254 of the anchor bolt 240 is designed and arranged in a locking element area on the anchor bolt 240 such that the anchor bolt 240 has a larger cross-section in the locking element area than outside the locking element area.

[0092] The locking element 254 of the anchor bolt 240 is made of an elastic material, for example, an elastic plastic. The outer diameter of the locking element 254 is slightly larger than the cross-section of the recess 252 of the mounting part 248 of the rail bracket lower part 216. When the rail bracket lower part 216 is placed onto the anchor bolt 240 in the direction of the shaft wall 18, and thus in the insertion direction, the locking element 254 of the anchor bolt 240 is slightly compressed, so that a resistance in the form of friction must be overcome during insertion.If the system component 248 is pushed onto the anchor bolt 240 beyond the locking element area, the safety element 254 expands back to its original size due to its elastic properties, and the lower rail bracket part 216 cannot overcome the locking element area of ​​the anchor bolt 240 on its own, i.e., not without a sufficiently large external force, and thus cannot be removed from the anchor bolt 240 in the opposite direction to the insertion direction. Therefore, with the anchor bolt 240 driven into the hole 42 in the shaft wall 18, the locking element 254 holds the elevator component holding system 259 in the inserted state after a change from the separated state to the inserted state.

[0093] The locking element area of ​​the anchor bolt 240 is spaced apart from a head 272 of the anchor bolt 240. The locking element area is positioned far enough from the head 272 of the anchor bolt 240 that a tool or holder used to drive in the anchor bolt 240 will not damage the locking element 254 during the driving process. The locking element 254 of the anchor bolt can, for example, be designed as a threaded sleeve with an internal thread made of elastic plastic. It is also possible that the locking element has no internal thread and is, for example, pressed onto the anchor bolt.

[0094] According to the enlarged view of the locking element 254 of the anchor bolt 240 in Fig. 9, the locking element 254 of the anchor bolt 240 has barbs 274 on its outer side, which are oriented and dimensioned such that the lower rail bracket part 216 can be placed on the anchor bolt 240 more easily than it can be removed from it. In particular, the elevator component holder 216 cannot be removed from the anchor bolt 240 without destroying the locking element 254. For this purpose, the locking element 254 has several circumferential barbs 274 arranged one behind the other, which have an outwardly rising flank 276 facing the shaft wall (not shown in Fig. 9), i.e., to the left in Fig. 9.

[0095] Finally, it should be noted that terms such as "comprising," "encompassing," etc., do not exclude other elements or steps, and terms such as "a" or "an" do not exclude a plurality. Furthermore, it should be noted that features or steps described with reference to one of the above embodiments may also be used in combination with other features or steps from other embodiments described above. Reference numerals in the claims are not to be considered as limitations.
