Method and installation system for installing elevator components

The invention relates to a method for installing an elevator component of an elevator system in a vertical shaft of a building with the aid of an installation system which can be moved in the shaft, wherein the elevator system has at least one car which can be moved in the shaft along guide rails.

The invention also relates to a mounting system for implementing said method.

An elevator system has a series of elevator components mounted in a vertical shaft of a building. The elevator system has guide rails fixed e.g. to the wall of the shaft and along which at least one car can travel upwards and downwards in the vertical direction. In most cases, the elevator components are mounted in the shaft by a plurality of mounting platforms which are initially guided into the shaft and fixed in the shaft. The elevator components, such as guide rails, are then mounted in the working area of the shaft by means of the mounting platform, which is accessible from the mounting platform. The installation platform is then released and reintroduced into the shaft at the upper shaft part and secured. With the expense of repeated installation and removal of the installation platform, the elevator components are thus installed layer by layer. The installation can be carried out as early as possible while the building is still under construction. Installation costs increase with increasing transport height. For buildings with high transport heights, significantly long installation times are required. This is associated with significant installation costs for the elevator system.

There are also proposals to use mounting baskets for mounting elevator components in the shaft. The mounting basket is suspended on a holding device in the shaft and can be moved up and down by means of a cable drive for mounting the elevator components in the shaft. The prior art is also a so-called "dummy car" which is suspended from a holding device fixed in the shaft and which can be moved up and down by means of a cable drive. In contrast to the mounting basket, the dummy car is guided on guide rails which have already been mounted and usually also have catching devices. Both the installation basket and the false car require a holding device for suspension purposes, which is fixed, for example, on the already completed shaft ceiling or on a temporary support or support point in the shaft. The use of temporary supports or support points as fixing points for the holding means allows the elevator components to be installed as early as possible when the shaft has not been completed. However, this is highly dependent on the progress of the shaft construction and is also associated with considerable construction time and installation costs.

It is an object of the invention to provide an elevator component for installing an elevator system and also an installation system for implementing the method, which method has a relatively short set-up time and a relatively low dependency on the progress of the shaft construction.

According to the invention, this object is achieved by a method of the type in which a mounting system is positioned in a shaft, said mounting system having a support platform and the mounting platforms being arranged one above the other and having a lifting device, wherein the support platform and the mounting platforms are alternately fixed in position in the shaft and the respective unpositioned platform is moved in a vertical direction relative to the stationed platform by means of the lifting device.

According to the invention, a mounting system with a support platform and a mounting platform is used in the method, the two platforms being connected to each other by means of a lifting device. The vertical distance which the two platforms assume between each other can be varied by means of the lifting device. Alternatively, one of the two platforms is fixed in position in the shaft and the other platform is moved in the shaft in a vertical direction relative to the fixed platform. This allows the mounting system to be moved vertically up and down in the shaft in the manner of a crawler track to mount elevator components such as guide rails or other cables or other sensors. The installation platform forms a working platform which is movable in relation to the support platform in the shaft and from which the elevator components can be installed in the shaft. The installation of the elevator components is largely independent of the construction progress of the shaft. The installation of the elevator components can be started as early as possible when the building has not yet been completed. This allows the elevator components to already be installed in the lower region of the building while the upper building region is still in construction work, so that the elevator system can then be installed in this lower building region.

The mounting system can be moved, for example, in a first step in which the support platform is fixed in position in the shaft in a first position, and in a second step the mounting platform is raised by means of the lifting device in order to mount the elevator component in the shaft, and in a third step the mounting platform is fixed in position in the raised position in the shaft, and in a fourth step the fixing of the support platform is released, and the support platform is lifted vertically upwards by means of the lifting device and is fixed in position again in a second position which is arranged above the first position.

In an advantageous embodiment of the method according to the invention, the support platform and/or the installation platform is supported on the shaft wall or is fixed to a support element on the shaft wall, so that it is fixed in position. Provision may be made for example for the support platform and/or the mounting platform to be fixed in position on a plate in a recess in the shaft wall or on a steel bracket fixed to the shaft wall.

It is advantageous when the support platform and/or the mounting platform are fixed to the guide rails of the elevator system so as to be in a fixed position. It is particularly advantageous when the support platforms as well as the mounting platforms are fixed to the rail, since this allows the entire mounting system to be moved along the rail in a caterpillar manner, wherein the support platforms and the mounting platforms are alternately fixed to the rail and the platforms that are not fixed are moved along the rail by means of the lifting device.

In a particularly preferred development of the method according to the invention, the guide rails are connected to one another in pairs at their ends by means of connecting elements, and the support platform and/or the mounting platform are supported on the connecting elements so as to be fixed in position. In a modified example of such a method, the connecting element performs in addition to the function of connecting together two guide rails directly adjacent to each other the function of applying a supporting force to the supporting platform and/or the mounting platform. The forces exerted by the support platform and/or the mounting platform can be transferred via the connecting element onto the guide rail and via said guide rail to the shaft base. This has the advantage that the shaft wall is not subjected to excessively high loads when the support platform and the mounting platform are fixed in position.

This is advantageous when in a first step the support platform is supported on a first coupling element, and in a second step the mounting platform is raised by means of the lifting device for mounting the elevator component, and in a third step the mounting platform is supported on a second coupling element provided on the above-mentioned first coupling element, and when in a fourth step the support platform is lifted vertically upwards by means of the lifting device and is supported on a further coupling element arranged above said first coupling element.

This is advantageous when the support platform is supported on the second connection element in the fourth step. Thus, the mounting platform and the support platform are supported on the same connecting element. This provides the option of initially building the installation system downhole when installing the elevator system and subsequently installing the first and second guide rails one above the other in the shaft by means of the vertically adjustable installation platform, it being possible for the first and second guide rails to be connected to each other by means of the first connecting element. The mounting platform can then be supported on the first connecting element, and thereafter the support platform can be pulled vertically upwards by means of the lifting device. The support platform can then likewise be supported on the first connecting element. The mounting platform can then be raised by means of the lifting device and a third rail can be fitted onto the second rail, said third rail being connected to said second rail by means of a second connecting element. The mounting platform may then be supported on the second connection element, and the support platform may then be pulled along.

The support platform and the mounting platform are preferably provided with coupling means which are releasably connected to second coupling means for supporting the support platform and the mounting platform on a connecting element to which the second coupling means are in each case fixed. This allows the mounting platform and the support platform to be supported on the connecting element by the first and second coupling means.

It is advantageous when the first coupling means is combined with said second coupling means. For this purpose, a cut-out may be provided, for example, on the second coupling means, it being possible for the first coupling means to engage at said cut-out.

In an advantageous embodiment of the method according to the invention, the second coupling means are in each case mounted on the connecting element and connected releasably to the guide rail. The vertical forces that occur can thus be transmitted directly to the connecting element by means of the first and second coupling means, it being possible for forces to be transmitted from the connecting element to the guide rail. In order to avoid the second coupling means being unintentionally separated from the connecting element, the second coupling means may additionally be connected to the guide rail in a releasable manner. For example, the second coupling means may be clamped to the rail.

As already mentioned, in particular the guide rail can be installed in a shaft of a building by means of the method according to the invention. In a first step, the support platform is preferably supported on a first connecting element, by means of which the first and second rails are connected to each other, and in a second step, a respective third rail is fitted on the upper end of the second rail by means of a mounting platform and is connected to the second rail by means of a second connecting element, and in a third step, the mounting platform is supported on the second connecting element. Then, in a fourth step, the support platform is lifted in the direction of the mounting platform by means of a lifting device and likewise supported on the second connecting element. Starting from the pit, the guide rails can thus be placed one on top of the other, connected to each other by means of connecting elements and additionally fixed to the wall of the shaft, and the support platform and the mounting platform can be supported on the connecting elements, wherein the mounting system moves in the shaft in the manner of a crawler.

The alternate fixing of the support platform and the mounting platform in the shaft not only allows a vertical upward movement of the support platform and the mounting platform from the pit, but also a vertical downward movement of the support platform and the mounting platform is possible. This allows the elevator components and the fitter to be transported vertically upwards and vertically downwards. For this purpose, the installation platform can be fixed in position in the shaft, and the support platform can then be lowered vertically downwards by means of the lifting device and then likewise fixed in position in the shaft. In a subsequent method step, the fastening of the mounting platform can then be released and the mounting platform can be lowered downwards by means of the lifting device. The mounting platform can then be secured again and immediately thereafter the support platform can be lowered further.

In an advantageous embodiment of the method the hoisting means are fixed to the support platform for hoisting the elevator component. With this structure, the support platform performs not only the function of supporting the lifting device and the mounting platform, but additionally the function of lifting additional elevator components. For this purpose, the lifting device is fixed to the support platform.

For example, a cable winch may be fixed to a support platform, by means of which the elevator components located below the support platform can be lifted.

In order to simplify the installation of the elevator components, it is advantageous when the hoisting means is fixed to the installation platform in order to lift the elevator components.

The mounting platform is preferably in the form of a work platform for the assembler.

This is advantageous when the mounting platform has a lifting device which makes it easier for an assembler to lift the elevator components.

It is advantageous that a hoisting crane is fixed to the mounting platform, wherein it is possible for elevator components to be raised by means of the mounting platform. In particular, the hoisting crane arranged on the mounting platform can more easily lift the guide rails fixed to the shaft wall by means of the mounting platform.

As mentioned in the introduction to the background, the invention also relates to a mounting system for implementing the method. The mounting system has a support platform and a mounting platform arranged one above the other, and also has a lifting device by means of which the vertical distance between the support platform and the mounting platform can be varied. The support platform and the mounting platform can alternatively be fixed in position in the shaft and the corresponding unsecured platform can be moved in the vertical direction relative to the secured platform by means of the lifting device.

This type of installation system has the advantage that the elevator components can be installed in the shaft of the building before the building is completed. The two platforms can be moved in the manner of a crawler by means of the lifting device. The mounting platform can form a working platform on which elevator components, in particular guide rails, can be mounted in the shaft.

In an advantageous embodiment of the installation system according to the invention, the support platform and/or the installation platform can be supported on a shaft wall or on a support element fixed to the shaft wall. For example, the support platform and/or the mounting platform is supported in a recess in a shaft wall or on a plate. Alternatively or additionally, the support platform and/or the mounting platform is supported on steel supports fixed to the shaft wall.

In a particularly preferred embodiment of the mounting system according to the invention, the support platform and/or the mounting platform can be fixed to a guide rail of the elevator system. This has the advantage that the shaft wall is subjected to only low levels of forces during movement of the mounting system, rather than the forces generated being transmitted from the mounting system to the pit via the guide rails.

As mentioned above, the guide rails can advantageously be connected to one another in pairs at the ends by means of connecting elements. This is advantageous when the support platform and/or the mounting platform is supported on the connecting element.

The first coupling means are preferably arranged on the support platform and on the mounting platform, wherein it is possible for said first coupling means to be connected in a releasable manner to the second coupling means, wherein said second coupling means can be fixed to the connecting element by means of two guide rails of the elevator system which can be connected to each other at the ends.

This is advantageous when the first and second coupling means are engaged with each other. For example, the second coupling device has a recess, into which a coupling element of the first coupling device, for example a movable extension arm, can be introduced.

As already mentioned before, it is particularly advantageous when the first coupling means of the mounting platform and the first coupling means of the support platform can be connected to the second coupling means simultaneously in a releasable manner, whereby this allows the mounting platform and the support platform to be supported to the connecting element by means of this same second coupling means, when the mounting platform and the support platform are assumed to be at a small vertical distance relative to each other.

In an advantageous embodiment of the mounting system according to the invention, the second coupling means can be fittingly connected to the connecting element in each case by means of two guide rails which are connected to one another at the ends.

The connecting element can preferably be connected to a guide rail of the elevator system in an interlocking manner. For example, the connecting elements can in each case be designed in a U-shaped manner and engage around mutually facing end regions of the two adjacent guide rails.

In each case, the first coupling means advantageously comprises two extension arms which are held so that they can be moved on the support platform or mounting platform so that they can be moved back and forth between the inoperative position and the operative position. In the inoperative position, the extension arms can be at the level of the guide rails already installed in the shaft of the building, and in the operative position, the extension arms can project outwards to such an extent that they can be connected to a second coupling device which is fixed to the connecting element by means of two guide rails which are connected to one another at the ends.

Advantageously, when the support platform comprises a support plate and two uprights which project vertically upwards from the support plate and each have first coupling means. The lifting device may be fixed to a support plate, the lifting device having a mounting platform at an upper end thereof, the upper end being clear of the support plate. The pillar protruding upwards from the support plate allows the first coupling means of the support platform to be connected to the second coupling means of the first coupling means already connected to the mounting platform, if the support platform is raised in the direction of the mounting platform, wherein the first coupling means are preferably arranged at the free end of the pillar. The length of the strut can thus substantially correspond to the smallest distance in the vertical direction which the support platform and the mounting platform can assume with the aid of the lifting device relative to one another.

It is particularly advantageous when the guide element applicable to the guide rail of the elevator system is arranged on the pillar. The guide element can be designed, for example, as a guide block which can be combined with a guide rail. The support platform can be guided in the vertical direction on a guide rail by means of the guide element, while the guidance of the mounting platform on said guide rail can be omitted.

In an advantageous embodiment, the mounting platform has a mounting plate on which the first coupling means and the coupling element are held so as to be movable back and forth between the inoperative position and the operative position. For example, the coupling elements may be held on the mounting platform so that they can be moved in a horizontal direction.

Advantageously, the mounting platform is supported on the support platform in a self-supporting manner by means of a lifting device. As a result, additional guide elements for the mounting platform can be dispensed with. In a further embodiment of such a mounting system according to the invention, the lifting device serves not only for moving the mounting platform in the vertical direction downwards and upwards relative to the support platform, but also for guiding the mounting platform in the vertical direction, wherein the mounting platform is likewise supported by the support platform like the lifting device.

In an advantageous development of the mounting system according to the invention, the lifting device comprises a scissor lift table. Such scissor lift tables are known per se to the person skilled in the art. The scissor lift may have a high support force and a relatively low self weight. If the support platform is supported on the first connecting element, the mounting platform can be raised by means of a scissor lift to such an extent that it can then be supported on the second connecting element. This then allows the support platform to be raised by the scissor lift to such an extent that it can be supported on the connecting element already used to support the mounting platform as well.

In a preferred embodiment of the mounting system according to the invention, the pulling device has a cable winch. This provides an alternative way of reducing the vertical distance between the support platform and the mounting platform by means of a cable winch and a tow cable. Furthermore, the load can be lifted by means of a cable winch.

Figures 1 to 5 schematically show a first embodiment of a mounting system according to the invention, indicated as a whole with the reference numeral 10. The mounting system 10 includes a support platform 12 having a support plate 14 from which two posts (16, 18) project vertically upward. In fig. 1, the struts (16, 18) have at their upper ends a first coupling device 20 and a corresponding 22, respectively, extension arm 23, which in its set operating position projects outwards in the horizontal direction and is connected to a second coupling device 24, respectively, which is shown in fig. 4. The first coupling means 20 and 22 are supported on a first connecting element 26 by means of second coupling means 24, respectively, and the first rail 28a and the respective rail 28b are connected to a second rail 30a and the respective rail 30b by means of said connecting element 26, respectively. The guide rails (28a, 28b) are fixed to the walls (34, 36) of a shaft 38 with the aid of a holding element 32.

In addition to the support platform 12, the mounting system 10 also has a mounting platform 40 which is held in a self-supporting manner on the support plate 14 of the support platform 12 by means of a lifting device in the form of a scissor lift table 42. With the aid of this scissor lift table 42, the mounting platform 40 can be moved in the vertical direction relative to the support platform 12.

The mounting platform 40 has a mounting plate 44 with an armrest 46 and forming a work platform for the assembler. Further first coupling means (48, 50) and an extension arm 23 movable in a horizontal direction between a non-operative position and an operative position are held on the mounting plate 44. The first coupling means (48, 50) of the mounting platform 40 are of the same design as the first coupling means (20 and 22) of the support platform 12.

In fig. 1, the support platform 12 is assumed at the position of the upper end of the first guide rail (28a, 28b), wherein it is supported in the vertical direction on the first connecting element 26 by means of the first coupling means (20, 22) and the second coupling means 24. In fig. 1, the mounting platform 40 is present at the location of the upper end of the second rail (30a, 30b), so that an assembler standing on the mounting plate 44 of the mounting platform 40 can fix the second connecting element 52, which has the same design as the first connecting element 26, to the upper end of the second rail (30a, 30 b).

As is clear from the exemplary embodiment shown in fig. 4 and 5, the first connecting element 26 likewise has a U-shaped design, as does the second connecting element 52, and comprises two limbs 54, 56 which are integrally connected to one another by means of a network 58. The first connecting element 26 engages mutually facing end regions of the left and right two rails (28a and 30a) and respectively (28b and 30b), wherein said second rails can be connected to the rails (28a, 30a) and respectively (28b, 30b) with the aid of connecting screws 60 and rest with their respective networks (54, 56) against the rear portions 70 of said rails (28a, 28b), (30a, 30b) facing towards the shaft wall 34 and respectively 36. However, a U-shape is not absolutely necessary for the connecting element (26, 52), but the connecting element (26, 52) can also have different shapes, as is known to the person skilled in the art, for example a T-shaped or flat design of the connecting element.

The struts 16 and 18 each have two guide elements 62,64 in the form of guide blocks, which are arranged at a vertical distance from one another and can each be brought into contact with a guide rail. Such guide blocks are known per se to the person skilled in the art.

The support plate 14 of the support platform 12 has on its underside a lifting device in the form of a cable winch 66, by means of which the elevator components can be raised or lowered. For this purpose, the fitter can be in position on the support plate 14.

As can be seen from fig. 4, the two coupling devices 24 have a plate-like design and can be fittingly mounted on the connecting element 26 and the respective upwardly directed end face 68 of the rail 52, wherein they lie flat against the rear face 70 of the rail and can be clamped to the rail with the aid of the clamping element 72. In each case, the second coupling device 24 has two inner recesses 74, 75 and two (outer) recesses (76, 77) at its top, which have the same design in the form of a trapezoid. Inner recesses 74 and respectively 75 and outer recesses 76 and respectively 77 are arranged on both sides of the guide rail.

Like the first coupling means (48, 50) of the mounting platform 40, the first coupling means (20, 22) of the support platform 12 each have two extension arms 23, which are of identical design, trapezoidal in cross-section and engage in an interlocking manner in the recesses of the second coupling means 24 in the expanded operating position. Fig. 5 shows the extension arm 23 of the first coupling means 48 of the mounting platform 40 in its extended position. In their operating position, the extension arms 23 of the first coupling means (48, 50) of the mounting platform 40 enter the two recesses 74, 75 of the first coupling means 20 of the second coupling means 24. The extension arms 23 of the first coupling means (20, 22) of the support platform 12 are at a relatively large distance from each other and in their working position engage the outer recesses 76, 77 in the second coupling means 24.

After the mounting of the second connecting element 52 at the upper end of the second rails 30a and 30b has been completed, the installer, with the aid of the holding element 32, fixes the third rails to the shaft walls 34, 36 and connects them to the second rails (30a and 30b) by means of the second connecting element 52, the fitter presenting a mounting plate 44 of the mounting platform 40 at a location which can be fitted to the third rails 78a, 78b of the second rails (30a, 30 b). The extension arms 23 of the first coupling means (48, 50) of the mounting platform 40 can then be extended to their operative position, where the extension arms 23 engage in the recesses 74, 75 in the second coupling means 24, as described above. The mounting platform 40 can thus be supported on the second guide rail (30a, 30b) by means of the first coupling device 48, 50 and the second coupling means 24 connected thereto and the second connecting element 52.

Since the mounting system 10 is now supported vertically by means of the mounting platform 40 and the second connecting element 52, the extension arm 23 of the first coupling means (20, 22) of the support platform 12 can be moved from the first connecting element 26 into its retracted inoperative position, and the support platform 12 can be raised with the aid of the scissor lift 52 in the direction of the mounting platform 40 to such an extent that the first coupling means (20, 22) of the support platform 12 reach into the second coupling means 24 provided on the second connecting element 52. The first coupling means (20, 22) of the support platform 12 can then be extended to its working position, where it enters an external recess (76, 77) in said second coupling means 24.

Fig. 2 shows the mounting system 10 as the support platform 12 moves from the position of the upper end of the first rail (28a, 28b) to the upper end of the second rail (30a, 30 b).

After the first coupling means (20, 22) are connected to the second coupling means 24 positioned on the second connecting element 52, the extension arms 23 of the first coupling means (48, 50) of the mounting platform 40 are moved to their inoperative position and the mounting platform 40 can be raised again by means of the scissor lift table 42. This is shown in figure 3. In a subsequent mounting step, further guide rails may be fittingly mounted on the third guide rails (78a, 78b) by means of the mounting platform 40, it being possible for the further guide rails to be fixed to the shaft walls (34, 36) with the aid of holding elements and to be connected to the third guide rails (78a, 78b) by means of further connecting elements. The installation method may then be repeated with the mounting platform 40 supported on the last mounted attachment element and the support platform 12 raised by scissor lift 42.

Thus, the mounting system 10 allows the support platform 12 and the mounting platform 40 to move in a caterpillar manner, wherein both platforms are supported on rails with the aid of the mounting system 10. The support platform 12 and mounting platform 40 need not be supported on a building.

Fig. 6, 7 and 8 schematically show a second embodiment of a mounting system according to the invention, which is designated as a whole by reference numeral 100 and which, like the third embodiment of a mounting system according to the invention which is shown by way of example in fig. 9, is likewise largely identical to the mounting system 10 described above with reference to fig. 1 to 5. Accordingly, the same reference numerals as used in fig. 1 to 5 are used for the same components in fig. 6, 7, 8 and 9, and in order to avoid repetition, reference may be made to the above description of these components.

The mounting system 100 differs from the mounting system 10 only in that the mounting plate 44 of the mounting platform 40 has a lifting device in the form of a hoisting crane 102, which makes it easier to mount the guide rails in the shaft 38.

The support platform 12 and the mounting platform 40 can be supported on said connecting elements (26, 52) by means of two guide rails (28a, 30a) and corresponding (28b, 30b) in the mounting system 100, which are connected to each other at their ends. The support platform 12 can be guided in the vertical direction with the aid of guide elements, for example guide blocks (62, 64), onto guide rails (28a, 28b, 30a, 30b), while the vertical guide of the mounting platform 40 can be dispensed with, since the mounting platform is held in a self-supporting manner on the support platform 12 with the aid of the scissor lift 42.

Fig. 9 shows a third embodiment of a mounting system according to the present invention, designated generally by reference numeral 120. The mounting system 120 differs from the previously described mounting systems 10 and 100 in that its support platform 12 and mounting platform 40 are not supported on rails but rather on the hoistway walls. To this end, the support platform 12 and mounting table 40 of the mounting system 120 have movable extension arms 123 that can enter recesses 123 in the hoistway walls (34, 36) to secure the support platform and, correspondingly, the mounting table 40 in position. This allows the mounting system 120 to move independently of the rails. The support platform 12 and the mounting table 40 of the mounting system 120 are supported directly on the hoistway walls (34, 36). Alternatively or additionally, the extension arms 123 of the mounting system 120 interact with support elements secured to the hoistway walls (34, 36) to secure the support platform 12 and the mounting platform 20 in a fixed position. The support member may use, for example, a steel support.

The mounting system 120 shown in fig. 9 differs from the mounting systems 10 and 100 described above with reference to fig. 1-8 in that it has a pulling device including a cable pulling system 125 having a pulling cable 126 and a cable winch 128, except at the scissor lift table 42. The traction cable 126 is fixed by a fixed end on the underside of the mounting platform 44 and is guided around deflection rollers (130, 132) which are mounted in a freely rotatable manner on the support plate 14 and can be wound and unwound by means of a cable winch 128 arranged on the support plate 14. This allows the vertical distance between the support platform 12 and the mounting platform 40 to be reduced by means of the cable winch 128, so that the support platform can be lifted by means of the cable winch 128 when the mounting platform 40 is secured in position in the shaft 38 by means of the extension arm 123. In the mounting system 120, the scissor lift table 42 is used to raise the mounting platform 40 when the support platform 12 is mounted in a fixed position in the shaft 38.
