[0003] Procedure for installing an elevator system

[0004] The invention relates to a method for installing an elevator system according to claim 1.

[0005] Installing an elevator is quite complex. Among other things, numerous elevator components must be fixed and aligned to the shaft walls in various installation steps. This requires determining the target positions of the elevator components within the shaft, and thus the installation locations for each step. Extensive measurements, often carried out manually by an installer, are necessary, for example, of distances within the elevator shaft. Reference lines are typically stretched across the shaft to determine the target positions and alignment of the elevator components.

[0006] It has already been proposed to support the installer in determining the target positions and alignment of elevator components. For example, EP 3 507 227 Bl suggests surveying the elevator shaft with a digital surveying system to obtain a digital model of the shaft. Based on this digital model, the target positions of the elevator components can be determined. EP 3 336 040 Al, for instance, proposes using a laser scanner to align guide rails for a cabin or a counterweight of the elevator system with respect to a reference line.

[0007] In contrast, the object of the invention is, in particular, to propose a method for installing an elevator system that enables simple and, in particular, precise installation of the elevator system. According to the invention, this object is achieved by a method with the features of claim 1.

[0008] The inventive procedure for installing an elevator system comprises the following procedural steps, which are carried out in the order specified below, but can also be carried out in a different order:

[0009] - Installation of a 3D position detection system in an elevator shaft of the elevator system, 2024P00038WÖ

[0010] - 2 -

[0011] - Selection of an installation step to be performed manually by an installer from a list of possible installation steps,

[0012] - Placing a first marker in the elevator shaft,

[0013] - Determining the position of the first marker using the 3D position detection system,

[0014] - Determining an installation location for the selected installation step based on a digital model of the elevator system,

[0015] - Determining a deviation of the position of the first marker from the installation location for the selected installation step,

[0016] - Displaying the aforementioned deviation on a display device,

[0017] - Determining the installation location for the selected installation step in the elevator shaft by the installer, starting from the first marker and the aforementioned deviation and

[0018] - The installer performs the selected installation step at the installation site.

[0019] The inventive method simplifies the installation of the elevator system, particularly because the installer does not have to determine the target positions of the elevator components to be installed, and thus the installation location for the corresponding installation step, through time-consuming manual measurements. Instead, after placing the first marker in the elevator shaft, the installer can determine the installation location of the selected installation step very easily and quickly based on the information displayed on the display device. By using a 3D position detection system, the position of the first marker, and therefore the installation location of the selected installation step, can be determined very precisely, enabling a highly accurate installation of the elevator system.Furthermore, in the inventive method, reference cords are not necessary, so that no time needs to be spent attaching the reference cords.

[0020] The 3D position detection system can be implemented, for example, as a laser tracker, an electronic total station, or an electronic tachymeter. Using the 3D position detection system, the position of an object, especially a marker, relative to the system can be determined; it primarily uses a laser for this purpose. 2024P00038WÖ

[0021] - 3 -

[0022] The 3D position detection system is typically installed in the so-called shaft head of the elevator shaft, i.e., in the area of ​​its upper end. It is also possible to install the 3D position detection system at another location in the elevator shaft, for example, in a so-called pit, i.e., in the area of ​​the lower end of the elevator shaft.

[0023] The 3D position detection system transmits its measurement data, specifically the marker's position, to a control unit. This transmission can be wired or wireless. The control unit can be located inside or outside the elevator shaft and may be, for example, a personal computer, an industrial computer, or a mobile device such as a tablet or smartphone. Alternatively, the control unit may be located in a central service center, to which the measurement data is transmitted via the internet, or the control unit may be an integral part of the 3D position detection system.

[0024] The control unit stores a digital model of the elevator system or has access to one. This digital model might be stored in a service center, for example, and the control unit might access it via the internet. The digital model of the elevator system includes at least a digital model of the elevator shaft and the elevator components to be installed on the shaft walls, such as guide rails, rail brackets for supporting the guide rails, and shaft doors to be installed in shaft openings. In particular, the digital model includes other elevator components, such as the elevator car, and specifically all components of the elevator system.

[0025] The digital model of the elevator shaft is created by surveying the shaft before the elevator components are installed. Subsequently, based on the elevator system's design data, such as the dimensions of the elevator car, the target positions of the individual elevator components are defined within the digital model of the shaft, thus completing the digital model of the elevator system. This process can be automated or performed with the assistance of a person, such as the installer. A qualified professional knows how to create a digital model of the elevator system using the information described.

[0026] The control unit contains a list of possible installation steps during installation 2024P00038WÖ

[0027] - 4 - stored in the elevator system or the control unit has access to such a list. The list may, for example, be stored in a service center and the control unit may, for example, access the list via the internet. The list includes at least some of the installation steps necessary for the installation of the elevator system, in particular at least one, preferably several, and specifically all of the following installation steps:

[0028] - Drilling a hole in the shaft wall of an elevator shaft of the elevator system,

[0029] - Fixing a rail bracket to a shaft wall of the elevator shaft of the elevator system,

[0030] - Aligning a guide rail section to guide a cabin or counterweight of the elevator system,

[0031] - Installing a shaft door in a shaft opening of the elevator shaft of the elevator system.

[0032] A screw is inserted into the aforementioned hole in the shaft wall, or an anchor bolt is driven in, which is used to fix a rail bracket to the shaft wall. Rail brackets have elongated holes through which a screw or anchor bolt passes, allowing the position of the rail bracket relative to the aforementioned hole to be adjusted within certain limits. A guide rail of an elevator system typically consists of individual guide rail sections that are stacked on top of each other and individually aligned. These guide rail sections are attached to a shaft wall of the elevator shaft using rail brackets, and their precise position relative to the shaft wall can be adjusted within certain limits.

[0033] The list of possible installation steps is displayed on a display and input device, such as a tablet or mobile phone. The installer selects the desired installation step on the display and input device. Alternatively, the control unit may automatically select the required installation step and display it on the display and input device or on a display-only device, such as a monitor.

[0034] The first marker is designed in such a way that its position can be determined particularly well and accurately by the 3D position detection system. The first and any subsequent markers used can be designed, in particular, as a special prism for use with 3D position detection systems. Such markers are also known as 2024P00038WÖ

[0035] - 5 -

[0036] The term "target" is used. The first marker can be placed, in particular, on a shaft wall of the elevator shaft, a rail bracket, a guide rail section, a shaft door, or even on a tool used when carrying out the installation step to be performed, for example, on a drill.

[0037] The first marker is placed by the installer, particularly in the vicinity of the installation location for the next step. The installer knows, for example, from experience, the precise location of this installation. By placing the first marker, the installer indicates the area where the next installation step will be performed. For instance, the installer might follow a rule that the first marker should always be placed above this area.

[0038] The information about the position of the first marker is transmitted by the 3D position recognition system to the control unit, which then uses this information, the selected installation step to be performed, and the digital model of the elevator system to determine the installation location for that step. For example, the installation location could be the target position of the drill hole when drilling a hole in a shaft wall, the target position of the rail bracket when fixing a rail bracket to a shaft wall, the target position of the guide rail section when aligning a guide rail section, and the target position of the shaft door when installing a shaft door.

[0039] The control unit determines, based on the described installation location for the selected installation step and the position of the first marker, how far the specified installation location deviates from the position of the first marker. This deviation is determined based on the installation step, either vertically and in one horizontal direction, or vertically and in two perpendicular horizontal directions. For the installation location involving drilling a hole in a shaft wall, one horizontal direction—the horizontal direction along the shaft wall—is sufficient. For the other installation steps mentioned above, two horizontal directions are necessary, for example, along the shaft wall and perpendicular to the shaft wall. The design of the marker and the holder are also taken into account when determining this deviation.For example, the position of the first marker determined by the 3D position detection system can be a fixed 2024P00038WÖ.

[0040] - 6 -

[0041] The distance to the shaft wall where the first marker is located would be fixed. This fixed distance would be taken into account as an offset when determining the aforementioned deviation.

[0042] The deviation of the first marker's position from the installation location for the selected installation step, as determined as described, is displayed on a display device, specifically the display and input device described above. The deviation can be displayed, for example, in millimeters in the vertical direction and in one or both of the horizontal directions described above. For this purpose, the deviation is transmitted from the control unit to the display device, either via cable or wirelessly.

[0043] Based on the first marker and the aforementioned deviation, the installer determines the installation location of the selected installation step, for example, the target position of a drill hole in a shaft wall or the target position of a rail bracket, a guide rail section, or a shaft door. The installer then carries out the selected installation step at the installation location.

[0044] The installer can, for example, drill a hole in a shaft wall at the desired position of a borehole using a drill, or move and fix a rail bracket, a guide rail section or a shaft door so that they are in their respective desired positions.

[0045] It is also possible to determine the target position of a drill hole by placing the first marker on a rail bracket and determining the target position of the rail bracket as described above. The target position of the rail bracket then determines the target position of a drill hole, or the target positions of two drill holes for fixing the rail bracket in question. The rail bracket thus serves as a template for defining the target positions of the drill holes.

[0046] It is possible that the procedural steps are:

[0047] - Determining the position of the first marker using the 3D position detection system,

[0048] - Determining the deviation of the first marker's position from the installation location for the selected installation step,

[0049] - Display of the aforementioned deviation on the display device, 2024P00038WÖ

[0050] - 7 -

[0051] - Determining the installation location for the selected installation step in the elevator shaft by the installer, starting from the first marker and the aforementioned deviation and

[0052] - The selected installation step can be performed several times in succession by the installer at the installation site in order to bring the corresponding elevator component into its target position in several steps. This is particularly advantageous for installation steps involving rail brackets, guide rail sections, and shaft doors.

[0053] In one embodiment of the invention, the first marker is arranged on one of the aforementioned elevator components by means of a holder, wherein, in particular, a specific holder is used depending on the elevator component. An advantage of arranging the first marker by means of a holder is that a wide selection of commercially available, non-specifically adapted markers can be used, and only the holder needs to be adapted for use in an elevator shaft. This makes the method cost-effective. Furthermore, the holder can be specifically adapted to the desired application. This is especially true when a specific holder is used depending on the elevator component on which the first marker is to be arranged.

[0054] The holder can be positioned and attached to an elevator component, such as a shaft wall, a rail bracket, a guide rail section, or a shaft door, in various ways. For example, the holder can be temporarily screwed or glued to the elevator component. The holder can also incorporate one or more magnets, allowing it to be attached to a magnetizable elevator component, such as a guide rail section. The connection between the holder and the marker is established, for example, via a plug connection, which ensures a defined orientation of the marker relative to the holder.

[0055] In an embodiment of the invention, the holder has a recess corresponding to the contour of a guide rail section. This allows the holder to be arranged particularly securely and in a defined orientation on a guide rail section. Guide rails of elevator systems, and thus also guide rail sections, have 2024P00038WÖ

[0056] - 8 - typically has a T-shaped cross-section and thus a T-shaped contour. The transverse part is referred to as the rail foot, which is oriented towards the shaft wall to which the guide rail is attached. The longitudinal part, also referred to as the rail web, forms a guide surface for guiding the cabin or counterweight. The recess of the holder is designed to be complementary to the head section of the guide rail, which forms the running surface. The recess can thus accommodate the aforementioned head section of the guide rail with minimal play. If the holder has a magnet, the inside of the holder with the magnets forms a reference surface, and the opposite side has minimal play.This means that the holder and the first marker connected to the holder are positioned in a defined position opposite the running surface of the guide rail section, thus enabling a particularly precise alignment of the guide surface of the guide rail section, which is crucial for guiding the cabin or the counterweight.

[0057] In one embodiment of the invention, the holder has a stop for alignment with the elevator component on which the first marker is to be positioned. This allows the holder to be positioned particularly easily at a defined location relative to the elevator component. The stop can, for example, be located at the edge of an otherwise flat contact surface of the holder. In this case, the stop points away from the flat contact surface. It is also possible for the holder to have two stops, for example, at two abutting edges of its contact surface. Holders with stops are particularly suitable for mounting on rail brackets and shaft doors.

[0058] In an embodiment of the invention, when aligning a guide rail section for guiding a cabin or counterweight of the elevator system is selected as the installation step to be performed, the first marker is arranged on said guide rail section. Additionally, a second marker is arranged on an opposite guide rail section, the position of which is determined and used analogously to the position of the first marker. This enables the alignment of the two opposite guide rail sections relative to each other, which is necessary for the proper operation of the elevator system. It is also possible to arrange two markers on one guide rail section, particularly in the area of ​​the two ends of the guide rail section or in the area of ​​the rail brackets. This allows the guide rail section to be aligned with particular precision. 2024P00038WÖ

[0059] - 9 -

[0060] When using more than one marker, each marker is assigned a separate installation location and, in particular, an identifier, such as a number. When the marker's position is displayed as a deviation from its assigned installation location on the display device, the marker's identifier is also shown. This allows the installer to know which marker the displayed deviation refers to. The deviations are displayed sequentially for each marker individually. Since the 3D position detection system can only determine the position of a single marker and not the positions of multiple markers simultaneously, the installer selects which marker's position should be determined and the deviation displayed. This selection is made primarily using the display and input device described above.

[0061] When aligning the two opposing guide rail sections, a string connecting the two opposing brackets can also be used. If the two opposing guide rail sections are correctly aligned, the string will run precisely over an elongated test mark, for example, in the form of a groove, on both brackets. The installer checks this during alignment and thus when performing the corresponding installation step.

[0062] Additionally, the installer can use a so-called gauge, a rod of defined length, to check whether the two opposing guide rail sections have a specified, correct distance from each other. This is the case when the gauge fits horizontally exactly between the two opposing guide rail sections.

[0063] In an embodiment of the invention, when selecting the installation step of mounting a shaft door in a shaft opening of the elevator shaft of the elevator system, the first marker is positioned on said shaft door. Additionally, at least one second marker is positioned on said shaft door, the position of which is determined and used analogously to the position of the first marker. This enables particularly precise installation of the shaft door. The two markers are positioned, in particular, on a threshold located at the bottom of the shaft door, at the greatest possible distance from each other. By bringing the two markers into their respective target positions, the door threshold can be correctly aligned. Subsequently, the shaft door can be installed vertically.

[0064] - 10 - to be mounted. It is also possible to use an additional marker: two as described at the bottom of the shaft door and another on an upper, horizontal part of a door frame of the shaft door, the so-called mullion. The additional marker must be positioned so that it does not obscure either of the other two markers and thus prevent their positions from being determined. The additional marker can, for example, be positioned centrally between the two other markers on the mullion. This allows for particularly precise alignment of the shaft door.

[0065] Components of a drive system can be arranged between the shaft door and the cabin door of the elevator car. These drive system components are typically designed as two rollers that interact with a so-called "blade" on the cabin door when the cabin door and shaft door open and close simultaneously. These rollers must be adjusted for proper interaction with the blade. During this adjustment, one or more markers can be used, following the procedure described above.

[0066] In this embodiment of the invention, when drilling a hole in the shaft wall of the elevator shaft is selected as the installation step, the first marker is attached to a drill, which the installer uses to drill the hole in the shaft wall. This allows the installer to easily and precisely locate the required position of the drill hole, and thus the installation location, and therefore to drill the hole quickly and in the correct position. The marker is attached to the drill by means of a suitable holder.

[0067] In this embodiment of the invention, after the 3D position detection system is installed in the elevator shaft, a digital model of the elevator shaft is created using the 3D position detection system. The digital model of the elevator system is then created based on this model. This advantageously allows the same 3D position detection system to be used both for creating the digital model of the elevator shaft and for providing the installer with the described support during the installation of the elevator system. A marker, as described above, is also used to create the aforementioned digital model of the elevator shaft. The marker is placed at various locations in the elevator shaft, and its position is determined using the 3D position detection system. For the creation of the digital model, see 2024P00038WÖ

[0068] - 11 -

[0069] In this model, the marker is placed at a sufficient number of locations in the elevator shaft to capture an adequate number of measurement points. These measurement points form a so-called point cloud, from which the digital model of the elevator shaft is derived through appropriate post-processing. Such methods for creating a digital model of an elevator shaft are known to those skilled in the art.

[0070] In this embodiment of the invention, a digital model of the elevator shaft is created using a surveying system before the 3D position detection system is installed in the shaft. The digital model of the elevator system is then created based on this model. Additionally, three position markers are placed in the elevator shaft. It is also possible to place more than three position markers in the elevator shaft. After the 3D position detection system is installed in the elevator shaft, its position and orientation relative to the digital model of the elevator shaft are determined based on these position markers. This allows for the advantageous use of an existing digital model of the elevator shaft or a surveying system specifically designed or optimized for surveying elevator shafts.

[0071] The aforementioned surveying system can, for example, also be implemented as a 3D position detection system as described above. It is also possible, for instance, that the surveying system is implemented as described above in EP 3 507 227 Bl. The position markers can, for example, be designed as markers or holders for markers as described above. It is also possible that the position markers are designed as markings on which markers are placed after the 3D position detection system has been installed in the elevator shaft.

[0072] 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.

[0073] This shows:

[0076] Fig. 3 shows two opposing guide rail sections with markers attached to them.

[0077] Fig. 4 shows a marker from Fig. 3 in a top view,

[0078] Fig. 5 shows a side view of a shaft door of the elevator system to be installed, with markers arranged on it.

[0079] Fig. 6 shows the shaft door from Fig. 5 in a top view.

[0080] According to Fig. 1, an elevator shaft 10 of an elevator system (not shown) extends, by way of example, over three floors 12, at each of which the elevator shaft 10 has a shaft opening 14. The elevator shaft 10 is bounded by four shaft walls 22, one of which has the aforementioned shaft openings 14.

[0081] In the shaft opening 14 of the lowest floor 12, a shaft door 16 is already installed in the installation stage of the elevator shaft 10 shown in Fig. 1, which closes the shaft opening 14. During operation of the elevator system, a cabin (not shown) is moved vertically in the elevator shaft 10, thus enabling the transport of people and goods between the floors 12. When the cabin stops at a floor 12 to allow people to board or alight, a cabin door is opened together with the corresponding shaft door 16. During the movement of the cabin in the elevator shaft 10, the cabin is guided by guide rails (not shown in Fig. 1) running vertically in the elevator shaft 10. The guide rails consist of individual guide rail sections (40, 52 in Fig. 3), which are assembled and aligned during the installation of the elevator system.

[0082] Several installation steps must be carried out during the installation of the elevator system encompassing elevator shaft 10. These include, among others, the following installation steps:

[0083] - Drilling a hole in the shaft wall of the elevator shaft of the elevator system,

[0084] - Fixing a rail bracket to a shaft wall of the elevator shaft of the elevator system,

[0085] - Aligning a guide rail section to guide a cabin or counterweight of the elevator system,

[0086] - Installing a shaft door in a shaft opening of the elevator shaft of the elevator system. 2024P00038WÖ

[0087] - 13 -

[0088] These installation steps are carried out by an installer 18 in the elevator shaft 10. Fig. 1 shows a snapshot at the very beginning of the installation, where the installer 18 is standing on a shaft floor 20 of the elevator shaft 10. When carrying out each installation step, the installer 18 must know the installation location for that step. For example, he must know exactly where to drill a hole in a shaft wall 22 of the elevator shaft 10. The installer 18 must therefore determine the target position of the hole and thus the installation location for the installation step "Drilling a hole in a shaft wall of an elevator shaft of the elevator system".

[0089] For example, the installer screws a screw or drives an anchor bolt into the drilled hole, by means of which a rail bracket (45 in Fig. 3) can be fixed to the shaft wall 22. Rail brackets have elongated holes for this purpose, so that the position of the rail bracket relative to the aforementioned hole can be adjusted within certain limits. A rail bracket can thus be brought into a desired position when fixed to a shaft wall. In the installation step "Fixing a rail bracket to a shaft wall of the elevator shaft of the elevator system," this desired position corresponds to the installation location.

[0090] Using rail brackets, the installer fixes a guide rail section to the shaft wall 22 of the elevator shaft 10 and aligns it, i.e., brings it into its target position. This target position corresponds to the installation location in the installation step "Aligning a guide rail section to guide a cabin or counterweight of the elevator system".

[0091] The installer 18 also mounts the shaft door 16 in the shaft opening 14. He uses suitable fastening material (not shown) for this purpose. The shaft door 16 must also be brought into a designated position. This designated position corresponds to the installation location in the installation step "Mounting a shaft door in a shaft opening of the elevator shaft of the elevator system".

[0092] The installation locations for the individual installation steps are determined by a control unit 26 located on the shaft ceiling 24 of the elevator shaft 10, based on a digital model of the elevator system. The digital model of the elevator system is derived from 2024P00038WÖ

[0093] - 14 -

[0094] The system requires design data of the elevator system, such as the dimensions of the elevator car, and a digital model of the elevator shaft 10 created by surveying the shaft. To survey the elevator shaft 10, a 3D position detection system 28 is positioned or fixed at the shaft head 24 and thus located within the elevator shaft 10. The 3D position detection system 28 can determine the position of a marker 30. For surveying the elevator shaft 10, the marker 30 is positioned at various locations within the shaft, and its position is determined by the 3D position detection system 28. To create the digital model of the elevator shaft 10, the marker 30 is positioned at a sufficient number of locations within the shaft to capture an adequate number of measurement points. These measurement points form a so-called point cloud, from which the digital model of the elevator shaft 10 is derived through appropriate post-processing.The 3D position recognition system 28 transmits the measurement data for the individual measuring points via a signal connection not shown to the control unit 26, which, as described, creates the digital model of the elevator shaft 10 and, taking into account the construction data of the elevator system, generates the digital model of the elevator system.

[0095] The control unit can also be located in a service center accessible via the internet or be part of the 3D position recognition system. The breakdown of the various steps for creating the digital model of the elevator system may differ from the breakdown described.

[0096] It is also possible that, prior to installing the 3D position detection system 28 in the elevator shaft 10, a digital model of the elevator shaft is created using a surveying system (not shown), and the digital model of the elevator system is then created based on this model. In this case, three position markers are specifically placed at different locations in the elevator shaft 10. These position markers are not all located at the same height in the elevator shaft 10. After installing the 3D position detection system 28 in the elevator shaft 10, its position and orientation relative to the digital model of the elevator shaft 10 are determined based on the three aforementioned position markers. For this purpose, a marker is successively placed at each of the position markers, and the position of the marker, and thus of the position marker, is determined using the 3D position detection system 28. 2024P00038WÖ

[0097] - 15 -

[0098] If the installer 18 wishes to perform an installation step, he selects the installation step to be performed from a list on a display and output device 32 shown in Fig. 2, for example in the form of a mobile phone. In the example shown in Fig. 2, the step "Sl" corresponds to the installation step "Drilling a hole in the shaft wall".

[0099] To determine the target position of the hole and thus the installation location for the installation step to be carried out, the installer 18 positions a first marker 30 on the shaft wall 22 using a suitable holder 34. The installer 18 can, for example, temporarily glue the holder 34 to the shaft wall 22. By selecting the location where the installer 18 positions the first marker 30 on the shaft wall 22, he determines the area in which he will carry out the selected work step, i.e., where he wants to drill the hole.

[0100] The 3D position detection system 28 then determines the position of the first marker 30 and transmits this information to the control unit 26. Based on the position of the first marker 30, the selected installation step, and the digital model of the elevator system, the control unit determines the installation location for the selected installation step. The control unit 26 then uses the installation location and the position of the first marker 30 to determine how far the installation location deviates from the position of the first marker 30. This deviation is determined based on the installation step, either in a vertical direction and one horizontal direction, or in a vertical direction and two mutually perpendicular horizontal directions.For the installation location where a hole is drilled into a shaft wall 22, a horizontal direction along the shaft wall 22 is sufficient; for the other installation steps mentioned above, two horizontal directions are necessary, for example, along the shaft wall 22 and perpendicular to the shaft wall 22. The design of the first marker 30 and the holder 34 is also taken into account when determining the aforementioned deviation.

[0101] The determined deviation of the position of the first marker 30 from the installation location for the selected installation step is displayed on the display and input device 32. The deviation is displayed, for example, in millimeters in the vertical direction and in one or both of the horizontal directions described above (see lower area in Fig. 2). For this purpose, the deviation is transmitted from the control unit 26 to the display and input device 32, particularly wirelessly. If, as when drilling a hole in the shaft wall 22, only one deviation is relevant in the horizontal direction, the other horizontal deviation is displayed.

[0102] - 16 -

[0103] Direction indicates a deviation from 0 (see Fig. 2, last line in the lower area).

[0104] Starting from the first marker 30 and the aforementioned deviation, the installer determines the installation location of the selected installation step, i.e., in the described example, the target position of the borehole. The installer then carries out the selected installation step at the installation location; in the described example, he drills the hole at the position determined as described, using a drill 36, into the shaft wall 22.

[0105] During the installation step "drilling a hole in a shaft wall," it is also possible that a marker 38 is positioned on the drilling machine 36 and the 3D position detection system 28 determines the position of this marker 38. The installer 18 must then position the drilling machine 36 to determine the installation location so that there is no deviation between the position of the marker 38 and the installation position.

[0106] The installer can, for example, drill a hole in a shaft wall at the desired position of a borehole using a drill, or move and fix a rail bracket, a guide rail section or a shaft door so that they are in their respective desired positions.

[0107] In order for the installer 18 to fix a rail bracket (45 in Fig. 3) to the shaft wall, he must, in particular, drill a second hole in the shaft wall 22. The second hole must, for example, be at a specified horizontal distance from the first hole.

[0108] If the installer wants to fix a rail bracket to the shaft wall 22, he first selects the corresponding installation step from the displayed list on the display and output device 32. In the example shown in Fig. 2, step "S2" corresponds to the installation step "Fixing a rail bracket to the shaft wall". He then positions the first marker 30 at a defined location on the rail bracket. The subsequent procedure is essentially the same as when drilling a hole in the shaft wall.

[0109] It is possible that the procedural steps are:

[0110] - Determining the position of the first marker 30 using the 3D position detection system 28,

[0111] - Determining the deviation of the position of the first marker 30 from the installation location for 2024P00038WÖ

[0112] - 17 - the selected installation step,

[0113] - Display of the aforementioned deviation on the display and input device 32,

[0114] - Determining the installation location for the selected installation step by the installer 18 starting from the first marker 30 and the aforementioned deviation and

[0115] - The selected installation step is performed multiple times at the installation site by the installer 18. The installer 18 repeats the aforementioned steps, in particular until the specified deviation is 0 or less than a predefined limit.

[0116] If the installer wants to align a guide rail section, he first selects the corresponding installation step from the displayed list on the display and output device 32. In the example shown in Fig. 2, step "S3" corresponds to the installation step "Aligning a guide rail section". He then positions the first marker 30 on the guide rail section 40 as shown in Fig. 3.

[0117] The first marker 30 is fixed to the guide rail section 40 by means of a special holder 134. According to Fig. 4, the holder 134 has a recess 142 corresponding to the contour of the guide rail section 40. The guide rail section 40 has a T-shaped cross-section and thus a T-shaped contour. A transverse part 44 is referred to as the rail foot, which is oriented towards the shaft wall 22, to which the guide rail section 40 is attached via a rail bracket 45. A longitudinal part 46 forms a guide surface for guiding the cabin or the counterweight. The recess 142 of the holder 134 is designed to be complementary to the part of the guide rail section 40 that forms the running surface. The holder 134 has two magnets 148 in the area of ​​the recess 142, by means of which the holder 134 is attached to the guide rail section 40.

[0118] The installer 18 also places a second marker 50 on a guide rail section 52 opposite the described guide rail section 40. The second marker 50 is placed at a location corresponding to the first marker 30 and in the same manner as the first marker 30 on the opposite guide rail section 52.

[0119] The subsequent procedure for aligning the guide rail sections is essentially the same as for fixing a rail bracket to the shaft wall. One difference is that a target position is defined for each of the two guide rail sections 40 and 52 (2024P00038WÖ).

[0120] - 18 - and the deviation of the respective target position from the corresponding marker is determined and displayed. The installer selects which marker is to be processed via the display and input device 32, i.e., the position to which marker is to be determined and the corresponding deviation is to be displayed. To indicate the displayed deviation, the number of the corresponding marker is shown, i.e., 1 for the first marker 30 and 2 for the second marker 50 (see Fig. 1 lower area, upper left corner).

[0121] When aligning the two opposing guide rail sections 40, 52, a cord 51 connecting the two opposing holders 134 can also be used. If the two opposing guide rail sections 40, 52 are correctly aligned, the cord 51 runs exactly over an elongated test mark (not shown), for example in the form of a groove, on both holders 134. This is checked by the installer 18 during alignment.

[0122] Additionally, the installer 18 can use a so-called gauge 53, a rod of defined length, to check whether the two opposing guide rail sections 40, 52 have a specified, correct distance from each other. This is the case when the gauge 53 fits horizontally exactly between the two opposing guide rail sections 40, 52.

[0123] If the installer wants to install a shaft door, he first selects the corresponding installation step from the displayed list on the display and output device 32. In the example shown in Fig. 2, step "S4" corresponds to the installation step "Installing a shaft door". He then positions the first marker 30, a second marker 50, and a third marker 54 on the shaft door 16, as shown in Figs. 5 and 6. The first marker 30 and the second marker 50 are located at opposite ends of a door threshold 56 that closes off the shaft door 16 at the bottom. The third marker 54 is located centrally on a mullion 56 that closes off the shaft door 16 at the top. The three markers 30, 50, and 54 are each located on the side of the shaft door 16 facing the interior of the elevator shaft 10.

[0124] The three markers 30, 50, 54 are each fixed to the shaft door by a special holder 234. According to Fig. 5, the holder 234 has a stop 258 that rests against an edge of the shaft door 16. The holder 234, and thus the marker connected to the holder, is part number 2024P00038WÖ.

[0125] - 19 - so that it is positioned at a defined position on the shaft door 16. The holder 234 can, for example, be temporarily glued to the shaft door 16 or have a magnet by means of which it can be fixed to the shaft door 16. The further procedure for fixing the shaft door 16 in the door opening 14 basically corresponds to the procedure for aligning a guide rail section.

[0126] 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.
