[0002] - 1 - Mobile transport device for transporting an assembly frame and method for inserting an assembly frame into a shaft
[0003] The invention relates to a mobile transport device for transporting an assembly frame and for inserting the assembly frame into a shaft, in particular an elevator shaft, with the features of claim 1 and a method for inserting the assembly frame into a shaft, in particular an elevator shaft, with the features of claim 7.
[0004] EP 4090620 B 1 describes a mobile transport device for transporting an assembly frame and for inserting the assembly frame into a shaft, comprising a base frame and a fixing device arranged on the base frame. The fixing device serves to secure the base frame to a shaft opening in a shaft wall and to prevent the mobile transport device from tipping over. The transport device also has a support frame on which the assembly frame is supported from above. The support frame is carried by the base frame and is arranged to be horizontally displaceable relative to the base frame such that, if the base frame is located outside the shaft and supported downwards on a base in front of the shaft opening, the support frame can be moved from outside the shaft through the shaft opening into the shaft.EP 4090620 Bl also describes a method for inserting a mounting frame into a shaft.
[0005] The mobile transport device described in EP 4090620 B 1 allows an assembly device with a mechatronic installation component arranged on a mounting frame to be easily and safely inserted into a shaft, in particular an elevator shaft. The assembly device can be used to perform automated assembly steps, for example, drilling holes in the shaft walls of an elevator shaft during the installation of an elevator in said elevator shaft.
[0006] The fixing device of the mobile transport device described in EP 4090620 B 1 is designed such that the fixing device, when fixing the base frame to the 2024P00241WÖ
[0007] - 2 - The shaft opening is supported on the shaft wall both inside and outside the shaft in such a way that it can withstand forces in the horizontal direction, particularly perpendicular to the shaft opening, and torques that could cause the transport device to tip over. It may be that fixing the base frame to a shaft opening with such a fixing device present on a transport device is not possible. Reasons for this could be that the shaft opening is too high and therefore the fixing device does not extend above the shaft opening, that the base frame must be positioned so far from the shaft opening that the fixing device cannot be supported on the inside of the shaft wall, or that the shaft wall cannot absorb the forces necessary to prevent the transport device from tipping over, for example, because it is constructed of masonry and not of cast concrete.It is also possible that the ground directly in front of the shaft opening has a threshold, making it impossible to bring the mobile transport device close enough to the opening. To enable the base frame to be fixed to the shaft opening in these cases, the fixing device would have to be correspondingly large, and therefore unwieldy and expensive.
[0008] In contrast, the object of the invention is, in particular, to propose a mobile transport device for transporting an assembly frame and for inserting the assembly frame into a shaft, and a method for inserting an assembly frame into a shaft, which can be used at many different shaft openings and are therefore flexible and cost-effective. According to the invention, this object is achieved with a mobile transport device having the features of claim 1 and a method having the features of claim 7.
[0009] The embodiments and exemplary embodiments of the invention described below relate equally to the mobile transport device and the method. In other words, features mentioned below, for example, with reference to the mobile transport device, can also be implemented as method steps, and vice versa. The mobile transport device is thus configured in such a way that it can be used in the described method.
[0010] The inventive mobile transport device for transporting an assembly frame and for inserting the assembly frame into a shaft, in particular an elevator shaft, has a base frame and a fixing device arranged on the base frame for 2024P00241WÖ
[0011] - 3 - Fixing the base frame in front of a shaft opening in the shaft wall and preventing the mobile transport device from tipping over. The transport device also has a support frame on which the mounting frame is supported from above. The support frame is carried by the base frame and is arranged to be horizontally displaceable relative to the base frame such that, if the base frame is located outside the shaft and rests downwards on a floor in front of the shaft opening, the support frame can be moved from outside the shaft through the shaft opening into the shaft. According to the invention, the fixing device has a base plate which has a through-hole and is designed and arranged on the base frame such that the fixing device, and thus the base frame, can be fixed to the floor in front of the shaft opening by means of an elongated fastening element projecting through said through-hole.This allows the base frame and mounting element to be easily fixed to the floor in front of the shaft opening. The floor in front of a shaft opening, especially the opening of an elevator shaft, is usually constructed, for example, of reinforced concrete, in such a way as to allow for secure fixing to the floor.
[0012] The mobile transport device is typically used when the building containing the shaft, particularly the elevator shaft, is still in a shell construction phase. The floor in front of the shaft opening therefore consists of bare concrete or wood without any additional covering, such as screed or subfloor, which is only applied after the mobile transport device has been removed. The floor in front of the shaft opening is thus a so-called unfinished floor. Holes for the aforementioned mounting element can easily be drilled into the floor in front of the shaft; these holes are later filled and / or concealed by the covering.
[0013] In addition to the described fixing device with the base plate, the mobile transport device can also have a further fixing device, for example for fixing to shaft walls of the shaft opening, in particular in accordance with EP 4090620 Bl. The two fixing devices can then be used alternatively or together to fix the base frame in front of the shaft opening.
[0014] The through-hole in the base plate is specifically located within the base plate, meaning it has a continuous, surrounding edge. It is also possible that the 2024P00241WÖ
[0015] - 4 - The through-hole is arranged at an edge of the base plate in such a way that it does not have a continuous circumferential edge, i.e., it is open at the edge of the base plate. In this case, the through-hole would be designed as a U-shaped recess at an edge of the base plate.
[0016] The base plate is designed as a primarily flat metal plate which, when fixed to the ground, rests flat against the ground. The base plate has more than one through-hole, for example, two, four, eight, ten, or more. It is fixed to the ground with more than one fastening element, for example, two or four, and has more through-holes than the number of fastening elements used. This allows for alternative through-holes to be used if a hole cannot be drilled into the ground at one location.
[0017] The elongated fastening element(s) used to fix the base plate to the ground is / are designed in particular as anchor bolts or screws. Anchor bolts are driven into a hole in the ground at one end and have a threaded end protruding from the hole, onto which a nut can be screwed. Screws can be screwed into holes in the ground, possibly after inserting a dowel.
[0018] The transport device is designed as a mobile transport device. This means that the entire transport device, including any mounting frame attached to the support frame, is mobile and can therefore be moved. The transport device may, for example, be equipped with casters on which it can be moved. It is also possible for the transport device to be moved using a forklift, for instance. Furthermore, the transport device can also be suspended from a cable and lifted and moved by a crane, for example.
[0019] The mounting frame can be used to hold a mechatronic installation component, for example, in the form of an industrial robot. With the mounting frame fixed in the shaft, automated assembly steps can be performed using the mechatronic installation component. The mechatronic installation component can, for example, be controlled according to the automated 2024P00241WÖ
[0020] - 5 - Installation component of WO 2017 / 016780 Al. The mounting frame can, for example, also support an installation platform or be designed as an installation platform from which a fitter can carry out assembly steps by hand or with the aid of tools in the shaft.
[0021] For the purposes of this text, a shaft is defined as an elongated space bounded by shaft walls. The shaft typically has a predominantly rectangular cross-section, although other cross-sections are also conceivable. The shaft extends primarily vertically. It is typically located within a building, but could also be situated, for example, within a bridge, a pier, or on a ship. The shaft walls and the floor in front of the shaft are typically made of reinforced concrete. However, they could also be made of metal, for example. The shaft serves primarily as an elevator shaft for an elevator system, in which, during operation, a cabin for transporting people and / or objects is moved in the direction of travel.The shaft can also serve other purposes, for example it can serve as a ventilation shaft or to accommodate pipes, electrical cables or similar items.
[0022] The shaft has a shaft opening through which it can be accessed from the side, i.e., horizontally. The shaft opening is thus located in one of the shaft walls. If the shaft is designed as an elevator shaft, a shaft door is installed in the shaft opening during the elevator's installation. This door allows passengers to enter and exit the elevator car during operation. Outside the shaft, in front of the shaft opening, is a floor on which the elevator car can stand and thus be supported from below. If the shaft is designed as an elevator shaft, this floor is the floor of the level accessible via the corresponding shaft opening and thus the shaft door.
[0023] After being lowered into the shaft, the mounting frame should be able to be moved within the shaft in the direction of displacement and thus positioned at different locations, particularly at different heights within the shaft. For this purpose, the mounting frame is attached to a lifting device, for example in the form of a rope, chain, or strap, either before or after being lowered into the shaft.
[0024] - 6 -
[0025] A relocation component, particularly in the form of a winch, is connected. The lifting device can be wound up or unwound by the winch, allowing the mounting frame to be moved within the shaft. Once inserted into the shaft, the mounting frame can be lifted upwards from the support frame. Before lifting, the mounting frame is connected to the transport device, such as the support frame, by a rope. The length of the rope is chosen so that the mounting frame cannot swing towards the wall opposite the shaft opening after being lifted. This prevents the mounting frame from swinging uncontrollably into the shaft after being lifted. After lifting, the mounting frame can be guided into the shaft in a controlled manner using the rope.
[0026] The base frame has a predominantly cuboid shape. The basic structure of the base frame is primarily constructed from metal profiles, which in particular have a rectangular cross-section. Further components may be attached to the basic structure.
[0027] The support frame also has a predominantly cuboid shape and thus a predominantly rectangular cross-section. It is not as tall as the base frame. The support frame therefore forms an upward-facing bearing surface onto which the mounting frame can be placed, so that it rests on this bearing surface and thus on the support frame from above. The support frame consists, for example, primarily of rectangular metal profiles welded together. The base frame supports the support frame, so that it rests on the base frame from above. In particular, it rests exclusively on the base frame.
[0028] In order to bring the mounting frame into the shaft, i.e., to bring it into the shaft from outside the shaft, the transport device including the mounting frame is positioned in a suitable position in front of the shaft opening, i.e., outside the shaft.
[0029] The base frame, and thus the transport device, is then fixed in front of the shaft opening using the fixing device. The support frame can then be moved horizontally towards the shaft relative to the base frame so that the support frame, and thus the mounting frame, is moved through the shaft opening and into the shaft. The support frame can be, for example, between 150 and 200 cm.
[0030] - 7 - relative to the base frame. The displacement does not have to be exclusively horizontal, but can also have a vertical component. It can therefore also be inclined or slanted.
[0031] Before the support frame is moved relative to the base frame, it is positioned primarily, and in particular entirely, above the base frame. A force resulting from the weight of the support frame and any mounting frame placed on it thus acts within the base frame. Moving the support frame towards the shaft causes it to extend horizontally beyond the base frame, shifting the direction of this resulting force horizontally towards the shaft. This ultimately results in the force acting outside the base frame, creating a tipping moment. This tipping moment is counteracted by the clamping device, preventing the base frame and, consequently, the transport device from tipping over.Therefore, to prevent the transport device from tipping over, it is not sufficient if the base frame is only secured against horizontal displacement.
[0032] The transport device can also be used to remove the mounting frame from the shaft. For this purpose, it is positioned and secured in front of the shaft opening, analogous to how the mounting frame is inserted. The support frame, without the mounting frame attached, is then moved through the shaft opening into the shaft. The mounting frame, with its transfer component, can then be placed onto the support frame. The support frame is then moved horizontally out of the shaft towards the base frame, thus moving it from inside the shaft to outside. The mounting frame can be detached from the support device either inside or outside the shaft.
[0033] In one embodiment of the invention, the fixing device comprises a base frame plate from which the base plate projects and via which the fixing device is connected to the base frame. This allows the base plate of the fixing device to be easily connected to the base frame and thus fixed to the base frame. In the state fixed to the ground in front of the shaft opening, the base plate projects, in particular, at an angle of approximately...
[0034] 90° from the base frame plate; the base plate and base frame plate thus close 2024P00241WÖ
[0035] - 8 - an angle of approximately 90°. The fixing device does not necessarily have to be grouted over a base frame plate. It is also possible for the base plate to be directly connected to the base frame, in particular to an underside of the base frame. In other words, the fixing device is essentially a two-part structure, with the two-part structure being defined by the base plate, which rests on or can be placed on the ground, and the base frame plate adjoining it.
[0036] In one embodiment of the invention, the fixing device is, for example, arranged on the base frame in a way that allows it to be removed by means of detachable fasteners. This advantageously allows the fixing device to be removed from the base frame during relocation of the mobile transport device. This avoids the risk of the fixing device getting caught on an obstacle, such as an uneven surface, during relocation. The fixing device, and in particular the base frame plate of the fixing device, is screwed to the base frame, especially by means of screws. The base frame has, for example, suitable threaded holes that correspond to corresponding through-holes in the fixing device, in particular in the base frame plate. The threaded holes thus form a coupling device for the base frame.It is also possible that the base frame has a bracket into which the fixing device, in particular the base frame plate, can be inserted or slid. It is also possible that the fixing device is permanently attached to the base frame. In this case, it may, for example, be permanently bonded to the base frame, such as by welding, or be integrally formed with the base frame.
[0037] In this embodiment of the invention, the fixing arrangement is connected to the base frame via a coupling device, which is also designed for connection to another attachment for the mobile transport device. This allows the coupling device to be advantageously used for multiple purposes, and the number of coupling devices on the base frame can be kept to a minimum. The coupling device is, for example, designed as one or more threaded bores or a suitable bracket, as described above. The attachment, which can also be connected to the base frame by means of the coupling device, can, for example, be designed as a drive unit with driven wheels.
[0038] - 9 - by means of which the mobile transport device can be moved easily and without excessive effort.
[0039] In one embodiment of the invention, the base plate of the fixing device is connected to the base frame plate of the fixing device in such a way that the angle between the base plate and the base frame plate is adjustable. If the base frame plate is vertical, the base plate can thus be folded up and down. This allows the base plate to be adapted to the contour of the floor when fixing it, resulting in a particularly secure fixation of the base plate to the floor.
[0040] If the ground has a threshold immediately in front of the shaft opening, it may be necessary to jack up the base frame, and thus the mobile transport device, on its side facing the shaft opening. This ensures that the threshold can be overcome when the assembly device is lowered into the shaft, preventing either the assembly device or any part of the mobile transport device from getting caught on the threshold. The base frame can be jacked up, for example, using at least one jack. This jacking causes the base frame to no longer run exactly parallel to the ground, but rather at an angle. By adjusting the angle between the base plate and the base frame plate, this angle can be adapted to the inclination of the base frame so that the base plate rests flat on the ground. This ensures that the base frame is securely fixed to the ground, even when inclined.
[0041] Furthermore, the base plate can be moved into a transport position, in particular by folding it upwards, before the mobile transport device is relocated. In the transport position, the base plate is further away from the ground, thus reducing the risk of the securing device getting caught on an obstacle during relocation. The base plate is connected to the base frame plate, in particular by one or more hinges. It is also possible to lock the base plate in its transport position.
[0042] In one embodiment of the invention, the fixing device can be arranged in different positions on the base frame. This allows the position of the fixing device to be adapted to the current situation. For example, the fixing device can be adjusted during a 2024P00241WÖ
[0043] - 10 - The mobile transport device must be positioned in a transport position and, during fixation to the ground, in a fixing position on the base frame. The fixing device, and in particular the base frame plate, may, for example, have several through holes which correspond to threaded holes in the base frame in different positions of the fixing device or the base frame plate. Alternatively or additionally, the fixing device, and in particular the base frame plate, may also have one or more elongated holes designed to allow the fixing device or the base frame plate to be positioned in several positions relative to the base frame.
[0044] The aforementioned problem is also solved by a method for inserting the mounting frame into a shaft, in particular an elevator shaft. The mounting frame is placed on a support frame of a mobile transport device and is supported from above by the support frame. The support frame is carried by a base frame of the transport device. The inventive method comprises at least the following steps:
[0045] - Moving the mobile transport device with the mounting frame in front of a shaft opening of the shaft,
[0046] - Securing the base frame and thus the transport device by means of a securing device arranged on the base frame in front of the shaft opening outside the shaft, thereby preventing the mobile transport device from tipping over, wherein the securing device has a base plate which has a through-hole and is designed and arranged on the base frame in such a way that, for securing the base frame, an elongated fastening element is guided through said through-hole and the securing device and thus the base frame is fixed to a base in front of the shaft opening, and
[0047] - Moving the support frame, which is arranged to be displaceable in a horizontal direction relative to the base frame, from outside the shaft through the shaft opening into the shaft, thereby bringing the mounting frame from outside the shaft through the shaft opening into the shaft.
[0048] The method has the advantages mentioned in connection with the mobile transport device. 2024P00241WÖ
[0049] - 11 - In an embodiment of the invention, the fixing device is arranged in front of a shaft opening on the base frame only after the mobile transport device has been moved with the mounting frame. This avoids the risk of the fixing device getting caught on an obstacle, such as an uneven surface, during the relocation of the transport device.
[0050] In this embodiment of the invention, when the mobile transport device with the mounting frame is moved in front of a shaft opening, the fixing device is in a transport position and is moved into a fixing position before the base frame is fixed to the ground in front of the shaft opening. This reduces the risk of the fixing device getting caught on an obstacle during the relocation of the transport device.
[0051] In an embodiment of the invention, the fixing device is arranged at a first location on the base frame in its transport position and at a second location in its fixing position, wherein the fixing device has a greater distance from the ground in its transport position than in its fixing position. This also reduces the risk of the fixing device getting caught on an obstacle during the relocation of the transport device.
[0052] In one embodiment of the invention, the fixing device comprises a base frame plate from which the bottom plate projects and via which the fixing device is connected to the base frame. To move the fixing device from its transport position to its fixing position, the angle between the bottom plate and the base frame plate is increased. This also reduces the risk of the fixing device getting caught on an obstacle during the relocation of the transport device.
[0053] It is noted that some of the possible features and advantages of the invention are described herein with reference to different embodiments of the mobile transport device 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. 2024P00241WÖ

[0062] According to Fig. 1, a mobile transport device 10 for transporting an assembly frame 11 and an assembly device 12, and for inserting the assembly frame 11 and the assembly device 12 into a shaft in the form of an elevator shaft 14, has a base frame 16. The assembly device 12 also has a mechatronic installation component in the form of an industrial robot 13, which is suspended downwards from the assembly frame 11. Directional terms such as up, down, vertical, or horizontal refer, as above and below, to the position of the mobile transport device 10 shown in Fig. 1, i.e., in a position supported on rollers 26 on a floor 28.
[0063] The base frame 16 has a lower frame 18 and an upper frame 20. The 2024P00241WÖ
[0064] - 13 - Both frames 18 and 20 have an identical rectangular cross-section and are made of rectangular metal profiles. The two frames 18 and 20 are connected to each other by four vertically extending, equally long beams 24, also made of metal profiles, which are arranged in the area of the corners of the frames 18 and 20. The two frames 18 and 20 of the base frame 16 are thus arranged parallel to each other. The base frame 16 therefore has a cuboid shape. The two frames 18 and 20 and the beams 24 thus form a basic structure of the base frame 16.
[0065] Four rollers 26 are arranged on the underside of the lower frame 18 of the base frame 16. These rollers support the base frame 16, and thus the transport device 10, on the floor 28 below the base frame 16. The rollers 26 are pivotally mounted on the lower frame 18 about a vertical axis and can be locked in different directions. This allows the transport device 10 to be moved on the floor 28, with the rollers 26 rolling along the floor 28.
[0066] The upper frame 20 of the base frame 16 supports a support frame 34, on which the mounting frame 11 of the mounting device 12 rests from above. It also has a rectangular cross-section and is also made of a rectangular metal profile. The cross-section of the support frame 34 is identical to the cross-sections of the two frames 18 and 20 of the base frame 16. An eyelet 36 is arranged at each of the four corners of the support frame 34, by means of which the transport device 10 can be suspended and moved using a suitable cable (not shown). The support frame 34 is connected to the upper frame 20 of the base frame 16 via two telescopic rail extensions (17 in Fig. 2) arranged parallel to each other (not visible in Fig. 1). This allows the support frame 34 and the mounting device 12 to be moved horizontally relative to the base frame 16 towards the elevator shaft 14.
[0067] The support frame 34 is moved relative to the base frame 16 by means of a spindle drive 38. The spindle drive 38 has a spindle 40 which is rotatably mounted in an L-shaped attachment 42 on the upper frame 20 of the base frame 16 and is fixed in the horizontal direction. The spindle 40 is also connected to the support frame 34 such that the support frame 34 is moved horizontally relative to the spindle 40 when the spindle 40 rotates. Thus, when the spindle 40 rotates, the support frame 34 is moved relative to the base frame 16. The spindle 40 can
[0068] - 14 - can be turned and thus rotated with a hand crank (not shown). It is also possible that a hand drill (not shown) is coupled to the spindle 40 and thus turned or rotated.
[0069] A first stop 44 is arranged at the end of the upper frame 20 of the base frame 16 that faces the elevator shaft 14. This first stop 44, together with a second stop 46 located at an end of the support frame 34 facing away from the elevator shaft, limits the horizontal displacement of the support frame 34 relative to the base frame 16. The two stops 44 and 46 come into contact with each other when maximum displacement is reached, thus preventing further displacement of the support frame 34 relative to the base frame 16 in the direction of the elevator shaft 14. This situation is illustrated in Fig. 2.
[0070] A fixing device 48 is also arranged on the base frame 16 for fixing the base frame 16 in front of a shaft opening 50 in a shaft wall 52 of the elevator shaft 14 and for preventing the transport device 10 from tipping over. In Fig. 1, the fixing device 48 is shown in its transport position, in which it allows the transport device 10 to be moved. The fixing device 48 has a base frame plate 54, which is connected to the base frame 16 via a coupling device 30 of the base frame 16. The coupling device 30 of the base frame 16 is formed by several, for example four, threaded holes. The base frame plate 54 has several, in particular four, through holes (56 in Fig. 6) through which screws 58, screwed into the threaded holes of the base frame, pass.The base frame plate 54 is thus fixed to the base frame 16 by the screws 58 via the coupling device 30 formed by the threaded holes. Other attachments, such as a drive unit with driven wheels (not shown), can also be connected to the base frame 16 via the coupling device 30.
[0071] The fixing device 48 also has a base plate 60, which is connected to the base frame plate 54 by several hinges 61. The hinges 61 allow an angle α (see Figs. 4 and 5) enclosed between the base frame plate 54 and the base plate 60 to be changed. In the transport position of the fixing device 48 shown in Figs. 1 and 4, the base plate 60 is folded upwards towards the base frame plate 54, so that the aforementioned angle α is significantly less than 90°. Thus, 2024P00241WÖ
[0072] - 15 -the vertical extension of the fixing device 48 downwards is less than in the fixing position of the fixing device 48 shown in Figs. 2 and 5. In the fixing position of the fixing device 48, the aforementioned angle a is approximately 90°.
[0073] On the lower frame 18 of the base frame 16, two support devices in the form of two vertically oriented spindles 66 are arranged in the area of its shaft-side end, although only one spindle 66 is visible in Figures 1 and 2. The spindles 66 can be rotated to extend further or less far downwards from the lower frame 18. In Figure 1, the spindles 66 are arranged so that they terminate above the floor 28 and thus do not impede the movement of the transport device 10.
[0074] To insert the assembly device 12 with the mounting frame 11 into the elevator shaft 14, the assembly device 12 must be placed onto the support frame 34 of the transport device 10. Initial placement takes place outside the building in which the elevator shaft 14 is located. The assembly device 12 is placed onto the support frame 34, in particular, using a crane. For this purpose, the assembly device 12 can be suspended from an eyelet 68. The eyelet 68 also serves to suspend the assembly device 12 from a lifting element (not shown) of a transfer component (not shown) in the form of a winch within the elevator shaft 14.
[0075] The described placement of the mounting frame 11 onto the support frame 34 can also be carried out after completion of installation work in an elevator shaft. This will be discussed in more detail below.
[0076] After the mounting frame 11 is placed on the support frame 34, the transport device 10, including the mounting frame 11, is moved to the shaft opening 50 of the elevator shaft 14. To insert the mounting device 12, and thus the mounting frame 11, into the elevator shaft 14, the base frame 16 with the fixing device 48 is first fixed in front of the shaft opening 50, thus preventing the transport device 10 from tipping over when the mounting frame 11 is inserted into the elevator shaft 14.
[0077] To fix the base frame 16 in front of the shaft opening 50, the base plate 2024P00241WÖ is first
[0078] - 16 - 60 of the fixing device 48 is folded downwards until the aforementioned angle a is approximately 90° (see Figs. 2 and 5). Subsequently, through through holes 62 (not shown in Figs. 1 and 2, see Fig. 9), for example, two holes 62 are drilled into the base 28 in front of the shaft opening 50, and anchor bolts 64 are driven into the holes 62. Finally, nuts (not shown) are screwed onto the external threads (not shown) of the part of the anchor bolts 64 that projects beyond the base plate 60, thus fixing the base plate 60, the fixing device 48, and the base frame 16 to the base 28 in front of the shaft opening 50.
[0079] The base plate 60 has, in particular, more through holes 62 than the number of anchor bolts 64 used. The base plate 60 can, for example, have two rows of nine through holes 62 each, as shown in Fig. 9. The base plate can also have more or fewer through holes.
[0080] To relieve the rollers 26, in particular the two shaft-side rollers 26, when inserting the mounting device 12 into the elevator shaft 14, the spindles 66 of the support device are unscrewed downwards from the lower frame 18 of the base frame 16 until they rest on the floor 28 and the two shaft-side rollers 26 are no longer subjected to any load. This state is shown in Fig. 2.
[0081] Subsequently, by turning or rotating the spindle 40 of the spindle drive 38, the support frame 34, and thus the mounting device 12 with the mounting frame 11, is moved horizontally relative to the base frame 16 towards the elevator shaft 14. During this process, the two telescopic rail extensions 17, which connect the support frame 34 to the upper frame 20 of the base frame 16, are pulled apart. This moves the support frame 34 with the mounting device 12 and the mounting frame 11 from outside the elevator shaft 14 through the shaft opening 50 into the elevator shaft 14. The movement continues until the first stop 44 on the upper frame 20 of the base frame 16 comes into contact with the second stop 46 of the support frame 34, thus ending the movement. This state is shown in Fig. 2.
[0082] After the movement into the elevator shaft 14 is complete, the mounting frame 11 and thus the mounting device 12 is attached via the eyelet 68 to a lifting element (not shown) of a relocation component (not shown) in the form of a winch in the elevator shaft 142024P00241WÖ
[0083] - 17 -connected. Using the winch and the lifting device, the mounting device 12 with the mounting frame 11 is then lifted from the support frame 34.
[0084] The support frame 34 is then moved back towards the base frame 14, and the fixing device 48 is released from the floor 28 in front of the shaft opening 50. The transport device 10 is thus returned to the state shown in Fig. 1. The transport device 10 can then be moved away from the shaft opening 50. Alternatively, the transport device 10 can remain fixed to the floor 28 in front of the shaft opening 50 until the assembly steps required by the assembly device 12 in the elevator shaft 14 have been completed and the assembly device 12 has been removed from the elevator shaft 14.
[0085] The assembly device 12 can then perform the necessary assembly steps in the elevator shaft 14. After completion of the assembly steps, the assembly device 12 is removed from the elevator shaft 14 again using the transport device 10. For this purpose, it is returned to the position shown in Fig. 2 and the assembly device 12 is placed back onto the support frame 34 using the winch and the lifting device. Subsequently, the steps described in connection with the insertion of the assembly device 12 are carried out in reverse order.
[0086] The base plate of the fixing device can be attached to the base frame with more or fewer than four screws. The bottom plate of the fixing device can also be fixed to the ground in front of the shaft opening with more or fewer than two anchor bolts or screws.
[0087] It is also possible that the fixing device is attached to the base frame only after the mobile transport device has been moved in front of the shaft opening. In this case, the fixing device is removable from the base frame. It is also possible that the fixing device is positioned differently on the base frame when the mobile transport device is moved compared to when it is fixed to the ground. In particular, when the mobile transport device is moved, the fixing device has a greater distance from the ground than when it is fixed to the ground.
[0088] Fig. 3 shows how the base frame 16 and thus the mobile transport device 102024P00241WÖ
[0089] - 18 - is fixed in front of a shaft opening 50 on the ground 28 if the ground 28 has a threshold 51 immediately in front of the shaft opening 50. The base frame 16, and thus the mobile transport device 10, is jacked up on its side oriented towards the shaft opening 50 with a jack 65 to such an extent that the threshold 51 can be overcome when the assembly device 12 is inserted into the shaft 14. Due to the jacking, the base frame 16 no longer runs exactly parallel to the ground 28, but is inclined to the ground 28. Before the base plate 60 is fixed to the ground 28, the angle enclosed between the base plate 60 and the base frame plate 54 is adjusted to the inclination of the base frame 16 relative to the ground 28 so that the base plate 60 lies flat on the ground 28. After the base frame 16 has been jacked up with the jack 65 as described, the spindles 66 can optionally be turned out of the base frame 16 so that they rest on the ground 28.The jack 65 could then be removed.
[0090] Figures 7 and 8 show fixing devices 48, which can be fixed at various positions on the base frame 16. The fixing devices according to Figures 7 and 8 differ from the fixing device 48 according to Figure 6 only in the design of the through holes 56.
[0091] The base frame plate 54 of the fixing device 48 according to Fig. 7 has not only four through holes 56 like the base frame plate 54 of the fixing device 48 according to Fig. 6, but a total of eight through holes 56. Four through holes 56 are arranged one above the other in such a way that the base frame plate 54 can be fixed to the base frame 16 at two different distances from the base 28. The base frame plate 54 of the fixing device 48 according to Fig. 8 has four through holes 56 in the form of elongated holes. The elongated holes are arranged so that the base frame plate 54 can be fixed to the base frame 16 at different distances from the base 28.
[0092] It is also possible that the base frame plate and the bottom plate of the fixing device are arranged immovably relative to each other, i.e., they form a fixed angle α, in particular of 90°. The fixing device is then, for example, designed as a metal angle with the described through-holes in the base frame plate and the bottom plate.
