Description

[Technical field]

[0001] The invention relates to a mobile transport device for transporting an installation frame and introducing the installation frame into a shaft, in particular an elevator shaft, with the features of claim 1 and to a method for introducing an installation frame into a shaft, in particular an elevator shaft, with the features of claim 15. [Background technology]

[0002] JP 2016-160091 A describes a mobile conveying device for conveying an installation frame and introducing the installation frame into an elevator shaft. The conveying device has a base frame and a fixing device arranged on the base frame for fixing the base frame to a shaft opening and preventing the conveying device from tilting.

[0003] WO 2017 / 016783 describes an installation device with mechatronic installation parts arranged on an installation frame. The installation device is used to perform automated installation steps, e.g. for drilling holes in the shaft wall of an elevator shaft as part of the installation of an elevator in said elevator shaft. To be able to perform installation steps at different heights in the elevator shaft, the installation device is suspended from a flexible suspension means so that it can be displaced in the elevator shaft by a displacement part arranged at the top of the elevator shaft by the suspension means. Before the installation device can perform installation steps in the elevator shaft, said installation device must be transported to the elevator shaft and introduced into the elevator shaft via a shaft opening. WO 2017 / 016783 is silent about how the installation device is transported and introduced into the elevator shaft. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2016-160091 A [Patent Document 2] International Publication No. 2017 / 016783 Summary of the Invention [Problem to be solved by the invention]

[0005] The transport and introduction of the installation device into the shaft, and thus also into the installation frame, is very complicated due to the necessary dimensions of the installation device and its weight. A further complication is that the elevator shaft at the shaft opening where the installation device is introduced usually does not have a solid floor or a temporary installation platform on which the installation device can be placed and on which the installer can step. [Means for solving the problem]

[0006] The object of the invention is therefore in particular to propose a mobile conveying device and a method for introducing an installation frame into a shaft, in particular an elevator shaft, which conveying device allows an easy and in particular safe introduction of the installation frame into the shaft. According to the invention, this object is achieved by a mobile conveying device having the features of claim 1 and by a method having the features of claim 15.

[0007] The mobile transport device according to the invention for transporting an installation frame and introducing the installation frame into a shaft, in particular an elevator shaft, has a base frame and a support frame on which the installation frame can be supported from above. The transport device also has a fixing device arranged on the base frame for fixing the base frame in a shaft opening in a shaft wall of the shaft and preventing tilting of the transport device. The support frame is supported by the base frame and is arranged horizontally movable relative to the base frame, so that when the base frame is arranged outside the shaft, the support frame, and therefore also the installation frame, can be moved from outside the shaft through the shaft opening into the shaft.

[0008] Thus, the mobile transport device including the installation frame can be transported or displaced up to the shaft opening and fixed in the shaft opening outside the shaft by the fixing device. The support frame can then be moved horizontally together with the installation frame relative to the base frame and thus pushed into the shaft through the shaft opening. The support frame and the installation frame are also supported by the base frame during said horizontal movement, so that the installation frame does not need to be additionally held or supported. In particular, the installation frame can also be arranged on the support frame such that the installation frame does not need to be rotated or tilted before or during introduction into the shaft. The horizontal movement of the support frame and the installation frame requires only a relatively small force, since it is only necessary to overcome the friction between the base frame and the installation frame. The installation frame can therefore be introduced very easily into the shaft. Also, when introducing the installation frame, the installer does not need to enter the elevator shaft or directly into the shaft opening. The introduction of the installation frame is therefore also particularly safe.

[0009] The embodiments described below relate equally to mobile transport devices and methods, in other words, features described below with reference to a mobile transport device for example can also be implemented as method steps and vice versa.

[0010] The transport device is designed as a mobile transport device. This should be understood to mean that the entire transport device, including the installation frame fitted to the support frame, is mobile, i.e. displaceable. The transport device can have, for example, rollers on which the transport device can be moved. It is also possible for the transport device to be displaced, for example, by a forklift. The transport device can also be suspended from a cable and lifted and displaced, for example, by a crane.

[0011] The installation frame can be used to hold a mechatronic installation part, for example in the form of an industrial robot. With the mechatronic installation part, an automatic installation step can be carried out in the shaft when the installation frame is in a fixed state. The mechatronic installation part can be designed, for example, according to the automatic installation part of WO 2017 / 016780. However, the installation frame can also, for example, carry an installation platform or be designed as an installation platform on which an installer can carry out the installation steps manually or with the help of a tool in the shaft.

[0012] The shaft is to be understood in this case as an elongated space delimited by shaft walls. In particular, the shaft has a predominantly rectangular cross section, but other cross sections are also conceivable. In particular, the shaft extends predominantly vertically. The shaft is in particular arranged in a building, but can also be arranged, for example, in a bridge, a pillar or a ship. The shaft walls consist in particular of concrete reinforced with reinforcement. However, they can also be made of metal, for example. The shaft is used in particular as an elevator shaft in an elevator installation, during the operation of the elevator installation, a car for transporting people and / or objects is displaced in the displacement direction. The shaft can also serve other purposes. For example, it can be used as a ventilation shaft or for accommodating pipes, electric cables, etc.

[0013] The shaft has a shaft opening, through which the shaft is accessible from the side, i.e. from the horizontal direction. The shaft opening is therefore arranged in one of the shaft walls of the shaft. If the shaft is designed as an elevator shaft, a shaft door is installed in the shaft opening during the installation of the elevator in the elevator shaft, through which passengers can enter and exit the elevator car during the subsequent operation of the elevator. In front of the shaft opening, i.e. outside the shaft, a floor is arranged, in particular on which the conveying device can stand. If the shaft is designed as an elevator shaft, said floor is the floor of a storey accessible via the corresponding shaft opening and thus the shaft door.

[0014] After being introduced into the shaft, the installation frame can be displaced in the shaft in a displacement direction and therefore has to be positioned at different positions, in particular at different heights in the shaft. For this purpose, before or after being introduced into the shaft, the installation frame is connected to a displacement part, in particular in the form of a winch, by means of a suspension means, for example in the form of a cable, a chain or a belt. The suspension means can be hoisted up or down by the winch, and thus the installation frame can be displaced in the shaft. After being introduced into the shaft, the installation frame can be hoisted upwards from the support frame.

[0015] In particular, the base frame has a primarily rectangular parallelepiped basic shape. The basic structure of the base frame is in particular made of a metal profile, in particular with a rectangular cross section. Further components can be arranged on the basic structure.

[0016] In particular, the support frame also has a mainly rectangular basic shape and therefore a mainly rectangular cross section. In particular, the support frame is not as tall as the base frame. The support frame therefore forms an upwardly facing support surface onto which the installation frame can be fitted, so that the installation frame is supported from above on the support surface and thus on the support frame. The support frame consists mainly of, for example, rectangular metal profiles welded together. The support frame is carried by the base frame so that it is supported from above on the base frame. In particular, it is only supported on the base frame.

[0017] With the fixing device arranged on the base frame, the base frame and therefore the transport device can be fixed to the outside of the shaft at said shaft opening. Fixing to the shaft opening should be understood to mean that the fixing device is supported on the part of the shaft forming the shaft opening so as to be able to support horizontal forces, in particular forces perpendicular to the shaft opening, and torques which may result in tilting of the transport device. The part of the shaft forming the shaft opening should be understood to mean in particular the shaft walls (inside the shaft and outside the shaft) but also the floor or ceiling in front of the shaft opening.

[0018] In order to introduce the installation frame into the shaft, i.e. to carry it from outside the shaft into the shaft, the transport device including the installation frame is placed in a suitable position in front of the shaft opening, i.e. outside the shaft. The base frame, and thus the transport device, is then fixed to the shaft opening by a fixing device. The support frame can then be moved horizontally in the direction of the shaft relative to the base frame, so that the support frame, and thus the installation frame, is moved into the shaft through the shaft opening. For example, the support frame can be moved between 150 and 200 cm relative to the base frame. The movement cannot extend only horizontally, but can also have a vertical component. It can therefore also extend obliquely or inclined.

[0019] Before the movement of the support frame relative to the base frame, the support frame is mainly, in particular completely, located above the base frame. Thus, forces resulting from the weight of the support frame and the installation frame fitted to the support frame act in the base frame. When the support frame moves in the direction of the shaft, the support frame protrudes horizontally beyond the base frame, and the effective direction of the resulting aforementioned forces is also moved horizontally in the direction of the shaft. Ultimately, this means that the resulting forces act outside the base frame, which results in a tilting moment on the base frame. This tilting moment is supported by the fixing device, which prevents the base frame and therefore the transport device from tilting. Therefore, it is not enough for the base frame to be fixed against horizontal movements.

[0020] The conveying device can also be used to remove the installation frame from the shaft. For this purpose, the conveying device is placed and fixed in the shaft opening in the same way as for introducing the installation frame into the shaft. The support frame is then moved into the shaft through the shaft opening in which the installation frame is not fitted. The installation frame with the displacement parts can then be fitted to the support frame. The support frame is then moved horizontally out of the shaft in the direction of the base frame, thus from the inside of the shaft to the outside of the shaft. The installation frame can be pulled away from the hanging means either inside or outside the shaft.

[0021] In one embodiment of the present invention, the support frame is arranged on the base frame via a telescopic extension rail, in particular two telescopic extension rails arranged parallel to each other. This allows a particularly simple construction of the transport device. Furthermore, the use of telescopic extension rails easily allows for an easy horizontal displacement of the support frame relative to the base frame and thus a particularly easy introduction of the installation platform into the shaft. Since the support frame with the fitted installation frame is very heavy, the telescopic extension rails used are designed as so-called heavy-duty telescopic extension rails.

[0022] The telescopic extension rail consists of at least two guide rails, the profiles of which extend into one another and can be moved relative to one another. A first guide rail, in particular an outer guide rail, is connected to a base frame, and a second guide rail, in particular an inner guide rail, is connected to a support frame. The guide rails can be connected, in particular screwed, for example to the base frame or to the support frame directly or via an intermediate bracket.

[0023] In one embodiment of the present invention, the base frame and the support frame each have a stopper designed and arranged to limit the movement of the support frame relative to the base frame. They can also each have more than one stopper, in particular two stoppers. It can thus be reliably prevented that the support frame is moved too far relative to the base frame and can no longer be held by the base frame. This ensures a particularly safe transport device.

[0024] The stops of the base frame and the support frame come into contact with each other when a maximum horizontal movement of the support frame relative to the base frame is reached, thus preventing further movement. The stops can be designed, for example, as small metal plates that can be welded or screwed to the base frame or the support frame.

[0025] In one embodiment of the invention, the support frame can be moved relative to the base frame by means of a spindle drive. This allows a particularly simple movement of the support frame relative to the base frame and thus a particularly simple introduction of the installation frame into the shaft. The spindle drive can be actuated manually, for example by means of a crank. It is also possible for the spindle of the spindle drive to be coupled to a hand drill, and for the spindle drive to be actuated by the coupled hand drill. Furthermore, it is possible for the drive, for example an electric motor for actuating the spindle drive, to be permanently arranged on the transport device.

[0026] The spindle of the spindle drive is specifically mounted to the base frame so as to be horizontally rotatable and immovable, and is connected at one end to a bearing frame such that as the spindle rotates, the support frame is moved horizontally relative to the spindle. As the spindle rotates, the support frame is moved relative to the base frame.

[0027] In one embodiment of the invention, the support frame is arranged at an incline to the horizontal. Said incline is given when the transport frame stands on a floor that extends at least approximately horizontally. The support frame is arranged at an incline, in particular when the transport device is arranged in the shaft opening of the shaft, so as to have a gradient in the direction of the shaft opening and thus in the direction of the shaft. This means that when introducing the installation frame into the shaft, the support frame and the installation frame can be automatically moved relative to the base frame through the shaft opening and into the shaft due to their weight, without the need for the application of further force. This makes the introduction of the installation frame into the shaft particularly easy.

[0028] The inclination can be, for example, 5-15 °, in particular about 10 °. In particular, a cable winch is arranged on the base frame, by means of which the support frame can again be pulled out of the shaft in the direction of the base frame. For this purpose, the cable of the cable winch is connected to the support frame. By means of the cable winch and the cable, the automatic movement of the support frame relative to the base frame when introducing the installation frame into the shaft can also be controlled, i.e. the automatic movement can be braked or prevented. In addition to the cable winch, a fastening mechanism of the support frame relative to the base frame can be provided, which fastening mechanism prevents the support frame from moving unintentionally relative to the base frame. The fastening mechanism can, for example, have a bolt, which is inserted into corresponding recesses in the support frame and in the base frame.

[0029] If the transport device has a spindle drive as described above, the support frame is in particular arranged horizontally, i.e. not tilted, however, a combination of spindle drive and tilted arrangement of the support frame is also conceivable.

[0030] In one embodiment of the invention, the fixing device has a primary fixing element for support on the outside of the shaft wall with the shaft opening, which can therefore provide a particularly reliable fixation and can particularly reliably prevent tilting of the transport device when moving the support frame relative to the base frame.

[0031] The outer side of the shaft wall is to be understood in this case as the shaft wall side that is directed outwardly when viewed from the shaft, and the inner side of the shaft wall is to be understood here as the shaft wall side that is directed inwardly when viewed from the shaft.

[0032] The fixing device has in particular two primary fixing elements, each arranged laterally on the base frame relative to the shaft opening. During fixing, the primary fixing element or elements extend upwards, in particular vertically, so that they protrude beyond the door opening and can thus be supported above the door opening on the outside of the shaft wall. When moving the support frame into the shaft, in particular there is a risk that the base frame, and thus the transport device, will tilt in the direction of the shaft. This can be reliably prevented by a support on the outside of the shaft wall with a shaft opening above the shaft opening.

[0033] The primary fixation element in particular has a spindle which during fixation extends mainly horizontally in the direction of the shaft wall. The spindle is rotatably and movably mounted in the primary fixation element, whereby said spindle can be displaced towards or away from the shaft wall by a corresponding rotation, for example by a manual crank. In particular, the spindle is displaced in the direction of the shaft wall such that it abuts against the outside of the shaft wall already before the support frame is moved in the direction of the shaft.

[0034] In one embodiment of the invention, the primary fixing element has a fixing arm which can be arranged in a fixed position and in a displaced position on the transport device. In its fixed position, the fixing arm allows the base frame to be fixed in the shaft opening, and in its displaced position, the transport device can be displaced. In the displaced position, the fixing arm can thus be displaced together with the transport device and does not have to be transported separately. This allows a particularly effective use of the transport device.

[0035] The length of the fixing arm can be varied in particular so that it can be adapted to the height of the corresponding shaft, in particular the shaft opening. In particular, it is designed in several parts, in particular in two parts, the two parts being designed in such a way that they can be moved into each other, separated from each other and fixed in the desired position relative to each other, for example by means of a bolt. In particular, the conveying device is designed in such a way that all parts of the fixing arm can be placed on the conveying device in a displaced position.

[0036] In one embodiment of the invention, at least a part of the fixed arm is arranged on the base frame so as to be pivoted about a pivot axis and can be transported from the fixed position to the displacement position and vice versa by pivoting about said pivot axis. This allows a particularly simple operation of the transport device and also ensures that no part of the fixed arm that is pivotably and therefore firmly connected to the base frame is lost. In this case, the fixed arm is designed in particular in two parts.

[0037] In one embodiment of the invention, the fixing device has a secondary fixing element for support inside the shaft wall with the shaft opening, which can therefore provide a particularly reliable fixation and can particularly reliably prevent tilting of the transport device when moving the support frame relative to the base frame.

[0038] In particular, the fixing device has two secondary fixing elements. During fixing, the secondary fixing element or elements extend downwards, in particular vertically, so that they protrude beyond the door opening and can thus be supported on the inside of the shaft wall below the door opening. When moving the support frame into the shaft, in particular there is a risk that the base frame and thus the transport device will tilt in the direction of the shaft. This can be reliably prevented by a support on the inside of the shaft wall with a shaft opening below the shaft opening. The secondary fixing element or elements also prevent the base frame and thus the transport device from moving horizontally away from the shaft opening.

[0039] The fixing device can also be designed in different ways: for example, it is conceivable for the fixing device to be clamped between the floor and the ceiling in front of the shaft opening.

[0040] In one embodiment of the invention, rollers are arranged on the base frame, by means of which the base frame can be supported on a floor below the base frame and roll on the floor, so that the transport device can be particularly easily displaced.

[0041] In particular, the transport device has four rollers, which are arranged on the base frame so as to pivot about a vertical axis and which can in particular be locked in different directions.

[0042] In one embodiment of the present invention, in addition to the aforementioned rollers, a support device is arranged on the base frame, by means of which the base frame can be supported on the floor in front of the shaft opening. In this way, the load on the rollers can be reduced when introducing the installation frame into the shaft. The support device has in particular two vertically aligned spindles rotatably and movably mounted in the base frame. By rotating them accordingly, they can be screwed off from the base frame so that they are supported on the floor in front of the shaft opening, and the base frame can be lifted up until at least two wheels arranged in the direction of the shaft opening are no longer loaded or are lifted off the ground.

[0043] In one embodiment of the invention, the base frame has a coupling device that is designed and arranged in such a way that a connection to a drive device for displacing the transport device can be generated. The transport device can thus be particularly easily displaced. This makes the transport device particularly easy to use. The coupling device can be designed, for example, as a metal profile, into which the drive device can engage. The drive device can be designed, for example, like a drive device according to EP 1 710 146 A1.

[0044] Instead of a coupling for a drive, the conveying device can also have a drive mechanism in the form of a driven roller or an electric motor.

[0045] In one embodiment of the invention, the support frame has a centering device, with which the installation frame is guided into a predefined fitting position when it is fitted onto the support frame, which on the one hand allows the installation frame to be fitted reliably in the position provided for it on the support frame and on the other hand makes fitting easier.

[0046] In particular, the support frame has a number of centering devices, in particular four centering devices. The centering devices in particular have insertion ramps, which interact with corresponding ramps on the extensions of the installation frame. When the installation frame is mated to the support frame, the ramps slide against each other and thus the installation frame can be brought to a specified mating position.

[0047] In one embodiment of the invention, the centering device has a fixing device, by means of which the installation frame fitted onto the support frame can be fixed onto the receiving frame, thereby preventing the installation frame from being pulled away unintentionally from the support frame and thus from the transport device.

[0048] The fixing device can have recesses, for example in the form of through holes, which are aligned at the designated fitting positions of the installation frame with corresponding recesses, for example in the form of through holes in the installation frame. To fasten the installation frame to the support frame, for example fixing pins can be inserted into the two recesses, whereby a reliable connection between the installation frame and the support frame is established. It is also possible that the fixing device is not located on the centering device but elsewhere.

[0049] In particular, the transport device has at least one eyelet from which the transport device can be suspended, so that the transport device can be particularly easily displaced, for example by means of a crane.

[0050] In particular, the transport device has two or more eyelets, in particular four eyelets, the eyelet or eyelets being arranged in particular on a support frame, in particular welded thereto.

[0051] The aforementioned object is also achieved by a method for introducing an installation frame into a shaft, in particular an elevator shaft, the installation frame being fitted into a support frame of a mobile transport device and supported from above by the support frame, the support frame being supported by a base frame of the transport device. The method according to the invention comprises at least the following steps: - fixing the base frame and thus the conveying device by means of a fixing device arranged on the base frame at the shaft opening on the outside of the shaft, whereby tilting of the conveying device is prevented; - moving a support frame arranged to be horizontally movable relative to the base frame from outside the shaft through the shaft opening into the shaft, whereby the installation frame is introduced from outside the shaft through the shaft opening into the shaft; has.

[0052] This method has the advantages mentioned in relation to the mobile transport device.

[0053] In particular, the steps are performed in the order specified, although deviations from this order are contemplated.

[0054] The fitting, in particular the first fitting of the installation frame to the support frame of the mobile transport device, can be carried out outside the building with the shaft. After the first fitting, the installation frame is fitted to the support frame of the mobile transport device, displaced to another shaft and, in particular after the installation work in one shaft is completed, introduced into the other shaft.

[0055] After mating, the included installation frame is displaced to the shaft opening of the shaft. This displacement can be intra- or inter-building. A wide variety of auxiliary equipment can be used for the displacement, such as drives, forklifts, cranes, or trucks. The transport equipment can also be moved and thus displaced manually, by one or more installers.

[0056] Before or after introduction into the shaft, the installation frame is connected to a suspension means which in particular extends in the shaft, so that after introduction into the shaft, the installation frame can be lifted upwards from the support frame by the suspension means and displaced in the shaft, for example by a displacement part arranged at the top of the shaft in the form of a winch.

[0057] After the installation frame has been attached and lifted, the support frame is in particular removed again from the shaft. For this purpose, it is moved horizontally relative to the base frame from the inside of the shaft to the outside of the shaft, i.e. in the direction of the base frame. The movements carried out when introducing the installation frame into the shaft are therefore carried out in the opposite direction.

[0058] The fastening to the shaft opening can then be released and the conveying device can be displaced away from the shaft opening, in this way the conveying device does not interfere with subsequent installation operations in the shaft.

[0059] After the installation work in the shaft is completed, the installation frame is removed from the shaft with the aid of a mobile transport device, as already mentioned above.

[0060] It should be noted that some of the possible features and advantages of the present invention have been described herein with reference to different embodiments of the transport device according to the invention and the method according to the invention, those skilled in the art will recognize that the features can be combined, adapted, transferred or exchanged in an appropriate manner to arrive at further embodiments of the invention.

[0061] Further advantages, features and details of the invention will become apparent from the following description of embodiments and from the drawings in which identical or functionally identical elements are provided with the same reference numbers, which are merely schematic and not to scale. [Brief description of the drawings]

[0062] [Figure 1] FIG. 13 shows a mobile transport device positioned in front of the shaft opening of the shaft, fitted with an installation frame. [Diagram 2] FIG. 2 shows the transport device of FIG. 1 fixed to the shaft opening and the installation frame pressed into the shaft. [Diagram 3] FIG. 13 shows a mobile transport device positioned in front of a shaft opening of a shaft in an alternative embodiment with an installation frame fitted thereto. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0063] According to Fig. 1, a mobile transport device 10 for transporting an installation frame 11 of an installation device 12 and for introducing the installation frame 11 and the installation device 12 into a shaft in the form of an elevator shaft 14 has a base frame 16. The installation device 12 also has a mechatronic installation part in the form of an industrial robot 13 arranged so as to hang over the installation frame 11.

[0064] The base frame 16 has a lower frame 18 and an upper frame 20. The two frames 18, 20 have identical rectangular cross-sections and consist of rectangular metal profiles. The two frames 18, 20 are connected to each other via four vertically extending bars 24 of equal length, also consisting of metal profiles, which are located in the corner areas of the frames 18, 20, respectively. Thus, the two frames 18, 20 of the base frame 16 are arranged parallel to each other. The base frame 16 thus has the basic shape of a rectangular parallelepiped. The two frames 18, 20 and the bars 24 thus form the basic structure of the base frame 16.

[0065] Arranged on the underside of the lower frame 18 of the base frame 16 are four rollers 26, via which the base frame 16, and therefore the transport device 10, is supported on a floor 28 below the base frame 16. The rollers 26 are arranged pivotably about a vertical axis on the lower frame 18 and can be locked in different directions. The transport device 10 can thus be moved on the floor 28 by the rollers 26 rolling on the floor 28. Arranged on a total of three sides of the lower frame 18 of the base frame 16 are coupling devices 30 in the form of metal profiles which are open at the bottom and which can be engaged by a driven transport device 32 and thus apply a driving force to the transport device 10. The drive device 32 can be designed, for example, like a drive device according to EP 1 710 146 A1.

[0066] The upper frame 20 of the base frame 16 supports a support frame 34 on which the installation frame 11 of the installation device 12 is supported from above. The support frame 34 is therefore arranged horizontally and therefore not inclined to the horizontal. It also has a rectangular cross section and consists of a rectangular metal profile. The cross section of the support frame 34 is identical to the cross sections of the two frames 18, 20 of the base frame 16. Eyelets 36 are arranged on the support frame 34 in the area of ​​each of its four corners, by means of which the transport device 10 can be suspended on suitable cables (not shown) and displaced. The support frame 34 is connected to the upper frame 20 of the base frame 16 via two telescopic extension rails (17 in FIG. 2) that are arranged parallel to each other and cannot be seen in FIG. 1. The support frame 34 and the installation device 12 can therefore be moved horizontally in the direction of the elevator shaft 14 relative to the base frame 16.

[0067] Movement of the support frame 34 relative to the base frame 16 occurs by a spindle drive 38. The spindle drive 38 has a spindle 40 that is rotatably mounted to an L-shaped appendage 42 on the upper frame 20 of the base frame 16 and cannot be horizontally movably mounted. The spindle 40 is also connected to the support frame 34 such that when the spindle 40 rotates, the support frame 34 is moved horizontally relative to the spindle 40. As the spindle 40 rotates, the support frame 34 is moved relative to the base frame 16. The spindle 40 can be pivoted and rotated by a hand crank (not shown). It is also possible for a hand drill (not shown) to be coupled to the spindle 40 and pivoted or rotated therewith.

[0068] A first stopper 44 is arranged on the upper frame 20 of the base frame 16 at its end facing towards the elevator shaft 14. This first stopper 44, together with a second stopper 46 arranged at the end of the support frame 34 facing away from the elevator shaft, limits the horizontal movement of the support frame 34 relative to the base frame 16. The two stops 44, 46 come into contact with each other when the maximum movement 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 is shown in FIG.

[0069] A fixing device 48 is also arranged on the base frame 16 for fixing the base frame 16 in a shaft opening 50 in a shaft wall 52 of the elevator shaft 14 and for preventing tilting of the transport device 10. FIG. 1 shows the fixing device 48 in a transport position allowing the displacement of the transport device 10. The fixing device 48 has two primary fixing elements 54 arranged laterally on the base frame 16, only one primary fixing element 54 being visible in FIGS. 1 and 2. The primary fixing element 54 has a two-part fixing arm (56 in FIG. 2) consisting of a lower arm part 60 pivotable about a pivot axis 58 fixedly arranged on the upper frame 20 of the base frame 16 and an upper arm part 62. The pivotable arm part 60 can be fixed relative to the upper frame 20 of the base frame 16 by means of a bolt 61. The upper arm part 62 can be inserted into the lower arm part 60 and fixed in various positions by means of a bolt (not shown). The length of the fixing arm 56 is thus adjustable and can be adapted to the height of the shaft opening 50. In its transport position, the upper arm portion 62 is fastened to the upper frame 20 of the base frame 16 by a bracket (not shown).

[0070] The fixing device 48 is also vertically movable and has a secondary fixing device in the form of two pins 64 arranged at the shaft end of the lower frame 18 of the base frame 16. In Fig. 1 and Fig. 2 only one pin 64 is visible. The pins 64 can be fixed at different heights by bolts (not shown). In Fig. 1, i.e. in the transport position of the fixing device 48, the pins 64 are arranged so that they terminate above the floor 28 and therefore do not hinder the displacement of the transport device 10.

[0071] Two support devices in the form of two vertically aligned spindles 66 are arranged on the lower frame 18 of the base frame 16 in the region of their shaft-side end, only one spindle 66 being visible in Figs. 1 and 2. The spindles 66 can, by a corresponding rotation, protrude further or a little below the lower frame 18. In Fig. 1, the spindles 66 are arranged such that they terminate above the floor 28 and thus do not hinder the displacement of the transport device 10.

[0072] In order to introduce the installation device 12 with the installation frame 11 into the elevator shaft 14, the installation device 12 must be fitted to the support frame 34 of the transport device 10. A first fitting is performed outside the building in which the elevator shaft 14 is located. The installation device 12 is fitted to the support frame 34, in particular by means of a crane. For this purpose, the installation device 12 can be suspended from the eyelet 68. The eyelet 68 is also used to suspend the installation device 12 from a suspension means (not shown) of a displacement part (not shown) in the form of a winch in the elevator shaft 14.

[0073] To bring the installation device 12, and therefore the installation frame 11, into a predetermined mating position, the support frame 34 has four centering devices 70, only two of which are visible in Figures 1 and 2. The centering devices 70 have conically arranged insertion ramps that interact with corresponding ramps on downwardly directed extensions 72 of the installation frame 11. When mating the installation frame 11 to the support frame 34, the corresponding ramps slide against each other to bring the installation frame 11 into the designated mating position shown in Figures 1 and 2.

[0074] Each of the centering devices 70 has a fixing device 74, by means of which the installation frame 11 fitted to the support frame 34 can be fixed to the receiving frame 34. The fixing device 74 has through holes (not shown) in the centering device, which are aligned with corresponding through holes (not shown) in the extensions 72 of the installation frame 11 at the designated fitting positions of the installation frame 11. To fix the installation frame 11 to the support frame 34, fixing pins 76 are inserted into the two through holes, thereby establishing a reliable connection between the installation frame 11 and the support frame 34.

[0075] The above-mentioned fitting of the installation frame 11 to the support frame 34 can also be carried out after the installation work in the elevator shaft has been completed, as will be explained in more detail below.

[0076] After fitting the installation frame 11 to the support frame 34, the transport device 10 including the installation frame 11 is displaced to the shaft opening 50 of the elevator shaft 14. The transport device 10 is positioned in front of the shaft opening 50 so that the vertical pin 64 of the secondary fixing device is positioned straight in the elevator shaft 14 and can be moved downwards over the floor 28. This position is shown in Figures 1 and 2.

[0077] To introduce the installation device 12, and thus the installation frame 11, into the elevator shaft 14, the fixing devices 48 are brought to their fixed position shown in FIG. 2, so that the base frame 16 and the transport device 10 are fixed in the shaft opening 50. For this purpose, the upper arm parts 62 are removed from their brackets on the upper frame 20 of the base frame 16 and inserted into their associated lower arm parts 60. The length of the fixing arms 56 is adjusted so that they project slightly beyond the shaft opening 50. The fixing arms 56 are then pivoted upwards about their pivot axes 58 to their fixed position and fixed in this position relative to the lower frame 18 of the base frame 16 by means of bolts 63.

[0078] The fixed arms 56, specifically the upper arm portions 62, each have at their upper end a spindle 78 which extends horizontally in the direction of the shaft wall 52 when the fixed arms 56 are in the fixed position. The spindle 78 is rotatably and movably mounted on the fixed arms 56 such that said spindle can be displaced towards or away from the shaft wall 52 by corresponding rotation by a manual crank 80. To fix the base frame 16, and thus the transport device 10, in the shaft opening 50, the spindle 78 is displaced towards the shaft wall 52 so as to abut against the outer side 82 of the shaft wall 52 and is thus supported on the outer side 82 of the shaft wall 52. As mentioned above, the fixed arms 56 project upwards beyond the shaft opening 50, so that the spindle 78, and thus the fixed arms 56, are supported above the shaft opening 50 on the outer side 82 of the shaft wall 52 which has the shaft opening 59. This state is shown in FIG. 2.

[0079] To bring the fixing device 48 into its fixed position, a secondary fixing device in the form of two pins 64 is also brought into its fixed position. For this purpose, the two pins 64 are pressed down sufficiently to terminate below the floor 28. In their lower region they therefore abut against, and can thus be supported on, the inner side 84 of the shaft wall 52 with the shaft opening 50. As the pins 64 terminate below the floor 28, they are supported below the shaft opening 50 on the inner side 84 of the shaft wall 52 with the shaft opening 50. This state is shown in FIG.

[0080] In order to relieve the load on the rollers 26, especially the two shaft-side rollers 26, when the installation device 12 is introduced into the elevator shaft 14, the spindles 66 of the support device are rotated downwards from the lower frame 18 of the base frame 16 so that they are supported on the floor 28 and the two shaft-side rollers 26 are no longer loaded. This state is shown in FIG.

[0081] After the base frame 14 and the transport device 10 are fixed to the shaft opening 50, the fixing pins 76 of the fixing device 74 are removed (see FIG. 1), thereby allowing the installation frame 11, and therefore the installation device 12, to be lifted from the support frame 34.

[0082] Subsequently, by pivoting or rotating the spindle 40 of the spindle drive 38, the support frame 34 and thus the installation device 12 with the installation frame 11 are moved horizontally relative to the base frame 16 in the direction of the elevator shaft 14. The two telescopic extension rails 17 connecting the support frame 34 to the upper frame 20 of the base frame 16 are pulled apart. Thus, the support frame 34 together with the installation device 12 and the installation frame 11 is moved from outside the elevator shaft 14 through the shaft opening 50 into the elevator shaft 14. The displacement continues until the first stop 44 on the upper frame 20 of the base frame 16 comes into contact with the second stop 46 on the support frame 34, thus terminating the movement. This state is shown in FIG. 2.

[0083] After the movement into the elevator shaft 14 has been completed, the installation frame 11, and thus the installation device 12, is connected via the eyelets 68 to a suspension means (not shown) of a displacement part (not shown) in the form of a winch in the elevator shaft 14. The installation device 12 with the installation frame 11 is then lifted from the support frame 34 by means of the winch and the suspension means.

[0084] The support frame 34 is then moved back towards the base frame 14 and the fixing parts 48 on the shaft opening 50 are pulled away, whereby the conveying device 10 is returned to the state shown in Figure 1. The conveying device 10 can then be displaced away from the shaft opening 50.

[0085] The installation device 12 can then carry out the necessary installation steps in the elevator shaft 14. After the installation steps have been completed, the installation device 12 is removed again from the elevator shaft 14 by the transport device 10. For this purpose, it is returned to the position shown in Figure 2 and the installation device 12 is fitted to the support frame 34 by means of a winch and a hanging means. The steps described in connection with the introduction of the installation device 12 are subsequently carried out in reverse order.

[0086] Figure 3 shows an alternative embodiment of a transport apparatus 110 fitted with a mounting frame 111 in the same position as the transport apparatus 10 of Figure 1 in front of the shaft opening 150 of the shaft 114, in front of the shaft opening 50. The transport apparatus 110 of Figure 3 differs only slightly from the transport apparatus 10 of Figure 1, so only the differences between the two transport apparatuses will be described here.

[0087] The vertically extending bars of the base frame 116 of the transport device 110 connect the lower frame 118 to the upper frame 120, but are not the same and have different lengths. The upper frame 120 of the base frame 116 is inclined towards the shaft opening 150, since the bars 124a facing the shaft opening 150 are shorter than the bars 124b facing away from the shaft opening 150. Thus, the support frame 134 supported by the upper frame 120 of the base frame 116 is also inclined towards the shaft opening 150.

[0088] The cable winch 140 is arranged on the upper frame 120 of the base frame 116 and can be operated by a manual crank 142. A cable, not shown, of the cable winch 140 is connected to the support frame 134. The cable winch 142 can be used to prevent or control automatic movement of the support frame 134 relative to the base frame 116 caused by the tilt of the support frame 134. After the installation device 112 is introduced into the shaft 114 and suspended on the cable of the displacement part, the support frame 134 can be pulled back from the shaft 114 using the cable winch 142 and thus returned towards the base frame 116.

[0089] Finally, it should be noted that terms such as "having" and "comprising" 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 of the other above embodiments. Reference signs in the claims should not be considered as limiting.
