Description

The invention relates to a method according to the preamble of claim 1, for mounting elevator components of an elevator installation in a vertical shaft of a building with the aid of a mounting system movable in the shaft, wherein the elevator installation has at least one car which can be moved along guide rails in the shaft.

Moreover, the invention relates to a mounting system according to the preamble of claim 7 for carrying out the method.

Such a method and system are by FR2782072A1 offebart.

Elevator systems comprise a series of elevator components which are mounted in a vertical shaft of a building. For example, elevator systems have guide rails which are fixed to a wall of the shaft and along which at least one car can be moved vertically upwards and downwards. The assembly of the elevator components takes place in many cases in that first several mounting platforms are introduced into the shaft and fixed in the shaft in a shaft section. Lifting components, for example guide rails, are then mounted by means of the assembly platforms in a working area of the shaft accessible from the assembly platforms. Subsequently, the mounting platforms are dismantled and re-introduced and set in a higher shaft section in the shaft. The assembly of the elevator components thus takes place in sections with recurring effort for the installation and removal of the mounting platforms. The assembly can already be carried out while the building is still under construction. The effort for assembly increases with increasing delivery height. For buildings with high headroom, considerable set-up times are required for the assembly platforms. This is associated with considerable installation costs for the elevator system.

It has also been proposed to use a mounting nacelle for the assembly of elevator components in a shaft. The assembly nacelle is suspended in the shaft on a holding device and can be moved by means of a cable drive up and down to mount elevator components in the shaft. There are also known as false cars, which can be suspended from a holding device fixed in the shaft and moved up and down by means of a cable drive. In contrast to assembly gondolas False Cars are guided on already mounted guide rails and usually also have a safety gear on. Both assembly gondolas and false cars require a suspension device for suspension, which is fixed, for example, to an already completed shaft cover or to temporary supports or support points in the shaft. The use of temporary support or Abstützpunkte as fixing points for the holding device allows the installation of elevator components already at a time in which the shaft is not yet finalized. However, this requires a strong dependence on the construction progress of the shaft and is also associated with considerable set-up times and installation costs.

The object of the present invention is to provide a method for assembling elevator components of an elevator installation and a mounting system for carrying out the method, which has shorter set-up times and less dependence on the construction progress of the shaft.

This object is achieved in a method of the generic type according to the invention that a mounting system is positioned in the shaft with a support platform and a mounting platform, which are arranged one above the other, and with a lifting and pulling device, wherein the support platform and the mounting platform fixed in the bay alternately be fixed and each not fixed fixed platform is offset by means of the lifting and pulling device relative to the stationary fixed platform in the vertical direction.

In the method according to the invention, a mounting system is used, which has a support platform and a mounting platform, which are connected to each other via a lifting and pulling device. By means of the lifting and pulling device, the vertical distance which the two platforms occupy to each other can be changed. Alternatively, one of the two platforms is fixed in place in the shaft and the other platform is displaced relative to the stationary fixed platform in the shaft in the vertical direction. This makes it possible to move the mounting system caterpillar vertically upwards and downwards to mount in the shaft elevator components, such as guide rails or an electrical wiring or sensors. The mounting platform forms a working platform which can be moved relative to the carrier platform in the shaft and from which elevator components can be mounted in the shaft. The installation of the elevator components is largely independent of the construction progress of the shaft. The assembly of the elevator components can already be started at a time when the building is not yet completely finished. This makes it possible to mount elevator components already in a lower area of the building so that subsequently an elevator installation can be put into operation in this lower building area, whereas building measures are still carried out in an upper building area.

The movement of the mounting system can for example be such that in a first step, the support platform is fixed in a fixed position in the shaft stationary and that in a second step, the mounting platform is raised by means of the lifting and pulling device for mounting elevator components in the shaft and that in a third step, the mounting platform is fixed in a fixed position in the shaft stationary and that solved in a fourth step, the fixation of the support platform and the support platform by means of the lifting and pulling device pulled vertically upwards and fixed in a second position disposed above the first position again is fixed.

In an advantageous embodiment of the method according to the invention, the support platform and / or the mounting platform are supported for their fixed fixation on the shaft wall or on support elements which are fixed to the shaft wall. It can be provided, for example, that the support platform and / or the mounting platform are fixed to niches or brackets of the shaft wall fixed or to steel beams that are fixed to the shaft wall.

It is advantageous if the carrier platform and / or the mounting platform are fixed to their stationary fixation on the guide rails of the elevator system. It is particularly advantageous if both the support platform and the mounting platform are fixed to the guide rails, because this gives the possibility to move the complete mounting system caterpillar along the guide rails, wherein alternately the support platform and the mounting platform are fixed to the guide rails and not fixed platform is offset by means of the lifting and pulling device along the guide rails.

In a particularly preferred embodiment of the method according to the invention, the guide rails are connected by means of connecting links in pairs end to end and the support platform and / or the mounting platform are supported for their fixed fixation on the connecting links. In such a refinement of the method, the connecting links, in addition to their function of connecting two guide rails that are directly adjacent to one another, also perform the function of exerting support forces on the support platform and / or the mounting platform. Via the connecting links, the forces exerted by the carrier platform and / or mounting platform can be directed to the guide rails and via these to the shaft bottom. This has the advantage that the shaft walls in the stationary fixation of the support platform and the mounting platform are not exposed to excessive loads.

It is advantageous if, in a first step, the carrier platform is supported on first connecting links and in a second step the mounting platform is raised by means of the lifting and pulling device for mounting elevator components and in a third step is supported on second connecting links arranged above the first connecting links, and if, in a fourth step, the carrier platform is pulled vertically upward by means of the lifting and pulling device and is supported on further connecting links arranged above the first connecting links.

It is favorable if the carrier platform is supported in the fourth step on the second connecting links. Thus, the mounting platform and the carrier platform are supported on the same links. This makes it possible to build the mounting system in the pit at the beginning of the installation of the elevator system and then to mount by means of the height-adjustable mounting platform in the shaft first and second guide rails one above the other, which are connected to each other via first links. Subsequently, the mounting platform can be supported on the first links and then the carrier platform can be pulled vertically upwards by means of the lifting and pulling device. The carrier platform can then also be supported on the first links. Subsequently, the mounting platform can be raised by means of the lifting and pulling device and on the second guide rails third guide rails can be placed, which are connected by means of second connecting members with the second guide rails. The mounting platform can then be supported on the second links and the carrier platform can then be retightened.

Preferably, the carrier platform and the mounting platform are provided with first coupling means, which are releasably connected for supporting the carrier platform and the mounting platform to the connecting members with second coupling means, which are each fixed to a connecting member. This allows the mounting platform and the carrier platform to support the links via the first and second coupling means.

It is advantageous if the first coupling devices are brought into engagement with the second coupling devices. For this purpose, for example, recesses may be provided on the second coupling devices, into which the first coupling devices can engage.

In an advantageous embodiment of the method according to the invention, the second coupling devices are each placed on a connecting member and detachably connected to a guide rail. By means of the first and second coupling means thus occurring vertical forces can be transmitted directly to a connecting member, from which the forces can be transmitted to guide rails. In order to avoid unintentional release of the second coupling means of the connecting members, the second coupling means can be additionally releasably connected to the guide rails. For example, it can be provided that the second coupling devices can be jammed with the guide rails.

As already mentioned, in particular guide rails can be mounted in a shaft of a building by means of the method according to the invention. Preferably, the support platform is supported in the first step on first links, via the first and second guide rails are connected to each other, and in the second step, by means of the mounting platform on the upper ends of the second guide rails in each case a third guide rail is placed, which by means of a second link with a second guide rail is connected, and the mounting platform is supported in the third step on the second links. Subsequently, in the fourth step, the support platform is raised by means of the lifting and pulling device in the direction of the mounting platform and also supported on the second connecting links. Thus, starting from the pit, the guide rails can be placed on each other, be connected by means of the connecting members and additionally fixed to the wall of the shaft, and the support platform and the mounting platform can be supported on the links, wherein the mounting system moves caterpillar in the slot.

The mutual fixation of the carrier platform and the mounting platform in the shaft not only allows the carrier platform and the mounting platform to move vertically upwards from the shaft pit, but it is also possible to move the carrier platform and the mounting platform vertically downwards. This allows elevator components as well as assembly personnel to transport vertically upwards and also vertically downwards. For this purpose, the mounting platform can be fixed in place in the shaft, and then the carrier platform can be lowered by means of the lifting and pulling device vertically downwards and then fixed in place also in the shaft. In a subsequent method step, then the fixation of the mounting platform can be solved and the mounting platform can be lowered by means of the lifting and pulling device down. Subsequently, the mounting platform can be fixed again and then the support platform can be further lowered.

In an advantageous embodiment of the method, a lifting device is fixed to the carrier platform for lifting elevator components. In such an embodiment, the carrier platform not only performs the function of supporting the lifting and towing device and the mounting platform, but also assumes the function of lifting further elevator components. For this purpose, a lifting device is fixed to the carrier platform.

It can be provided, for example, that a cable winch is fixed to the carrier platform, with the aid of which elevator components located below the carrier platform can be lifted.

In order to simplify the assembly of elevator components, it is advantageous if a lifting device is fixed on the mounting platform for lifting elevator components.

The mounting platform is preferably designed as a working platform for fitters.

It is advantageous if the mounting platform carries a lifting device that facilitates the lifting of elevator components for fitters.

It is advantageous if a lifting crane is fixed on the mounting platform, with the help of elevator components can be raised. In particular, a lifting crane arranged on the mounting platform facilitates the lifting of guide rails which are fixed to the wall of the shaft by means of the mounting platform.

As mentioned above, the invention also relates to a mounting system for carrying out the method. The mounting system has a support platform and a mounting platform, which are arranged one above the other, and a lifting and pulling device, with the aid of the vertical distance between the support platform and the mounting platform is variable. The support platform and the mounting platform are alternately fixed in the bay and fixed each not fixed platform is displaceable relative to the stationary fixed platform in the vertical direction by means of the lifting and pulling device.

Such a mounting system has the advantage that an assembly of elevator components in a shaft of a building can already be done even before the building is completely completed. The two platforms can be moved by means of the lifting and pulling device in the manner of a bead in the shaft. The mounting platform can form a working platform, from which the elevator components, in particular guide rails, can be mounted in the shaft.

In an advantageous embodiment of the mounting system according to the invention, the support platform and / or the mounting platform can be supported on the shaft wall or on support elements which are fixed to the shaft wall. It can be provided, for example, that the carrier platform and / or the mounting platform can be supported on niches or consoles of the shaft wall. Alternatively or additionally, it can be provided that the carrier platform and / or the mounting platform can be supported on steel girders which are fixed to the shaft wall.

In a particularly preferred embodiment of the mounting system according to the invention, the carrier platform and / or the mounting platform can be fixed to the guide rails of the elevator installation. This has the advantage that the shaft walls are acted upon during movement of the mounting system only with small forces, instead occurring forces are directed by the mounting system on the guide rails in the pit.

As already mentioned, the guide rails can advantageously be connected to one another in pairs by means of connecting links. It is advantageous if the carrier platform and / or the mounting platform can be supported on the connecting links.

Preferably, first coupling devices are arranged on the carrier platform and on the mounting platform, which can be detachably connected to second coupling devices, wherein the second coupling devices can be fixed to connecting members via which two guide rails of the elevator installation can be connected to one another at the end.

It is favorable if the first and second coupling devices can be brought into engagement with one another. For example, it can be provided that the second coupling devices have recesses into which coupling elements of the first coupling devices, for example movable arms, can be introduced.

As already mentioned, it is of particular advantage if a first coupling device of the mounting platform and a first coupling device of the carrier platform are detachably connectable with a second coupling device, because this makes it possible to support the mounting platform and the carrier platform via the same second coupling device on a connecting member, when the mounting platform and the carrier platform occupy a small vertical distance from each other.

In an advantageous embodiment of the mounting system according to the invention, the second coupling devices can each be placed onto a connecting element, via which two guide rails can be connected to each other at the end.

The connecting members are preferably positively connected to the guide rails of the elevator system. For example, it may be provided that the connecting members are each U-shaped and surround the mutually facing end regions of two adjacent guide rails.

Conveniently, each of the first coupling means comprises two arms which are movably supported on the support platform and on the mounting platform, respectively, so that they can be moved back and forth between a rest position and a working position. In the rest position, the arms can occupy a horizontal distance to already mounted in the shaft of the building guide rails, and in the working position, the arms can protrude so far outward that they can be connected to a second coupling device which is fixed to a connecting member via the two guide rails are connected to one another at the end.

It is advantageous if the support platform comprises a support plate and two of the support plate vertically upstanding supports, each one carry first coupling device. On the support plate, the lifting and pulling device may be fixed, which carries the mounting platform at its upper end facing away from the support plate. If the support platform is raised in the direction of the mounting platform, the supports protruding upwards from the support plate allow the first coupling devices of the support platform, which are preferably arranged at the free ends of the supports, to be connected to the second coupling devices already connected to the first coupling devices connected to the mounting platform. The length of the supports can thus essentially correspond to the vertical minimum distance that the support platform and the mounting platform can assume by means of the lifting and pulling device to each other.

It is particularly advantageous if guide elements are arranged on the supports, which can be applied to the guide rails of the elevator installation. For example, it can be provided that the guide elements are designed as guide shoes, which can be brought into engagement with the guide rails. By means of the guide elements, the support platform can be guided on the guide rails in the vertical direction, whereas a guide of the mounting platform can be omitted on the guide rails.

In an advantageous embodiment, the mounting platform has a mounting plate on which first coupling devices are held with coupling elements that can be moved back and forth between a rest position and a working position. For example, the coupling elements can be held displaceably on the mounting platform in the horizontal direction.

It is advantageous if the mounting platform is held by means of the lifting and pulling device cantilevered on the support platform. Additional guide elements for the mounting platform can be omitted. The Hubund drawbar is used in such an embodiment of the mounting system according to the invention not only to move the mounting platform relative to the support platform in the vertical direction upwards and downwards, but it also serves to guide the mounting platform in the vertical direction, wherein the mounting platform as well as the lifting and pulling device is supported by the carrier platform.

The lifting and pulling device comprises in an advantageous embodiment of the mounting system according to the invention a scissor lift. Such scissor lift tables are known per se to the person skilled in the art. You can have a high load capacity at a relatively low weight. If the carrier platform is supported on first connecting links, then the mounting platform can be lifted by means of the scissor lifting table so far that it can subsequently be supported on second connecting links. This then makes it possible to raise the support platform by means of the scissor lift so far that it can also be supported on the links, which already serve the support of the mounting platform.

In a preferred embodiment of the mounting system according to the invention, the lifting and pulling device on a winch. This makes it possible to reduce the vertical distance between the carrier platform and the mounting platform by means of the winch and a pull rope. In addition, loads can be lifted by means of the winch.

In the FIGS. 1 to 5 schematically a first embodiment of a mounting system according to the invention is shown, which is generally occupied by the reference numeral 10. The mounting system 10 comprises a support platform 12 with a support plate 14, projecting from the two supports 16, 18 vertically upwards. At their upper end, the supports 16, 18 each carry a first coupling device 20 or 22 with arms 23, which in FIG. 1 occupy a position in which they protrude in a horizontal direction to the outside and each with an in FIG. 4 shown second coupling means 24 are connected. The first coupling devices 20 and 22 are each supported on a first connecting member 26 via the second coupling devices 24, via which a first guide rail 28a or 28b is connected to a second guide rail 30a or 30b. The guide rails 28a, 28b are fixed by means of holding members 32 on shaft walls 34, 36 of a shaft 38.

In addition to the support platform 12, the mounting system 10 has an assembly platform 40, which is held in a cantilever manner on the support plate 14 of the support platform 12 via a lifting and pulling device in the form of a scissor lift. With the help of the scissor lift 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 which carries a railing 46 and forms a working platform for assembly personnel. On the mounting plate 44 further first coupling means 48, 50 are held with a displaceable between a rest position and a working position in the horizontal direction arms 23. The first coupling devices 48, 50 of the mounting platform 40 are configured identically to the first coupling devices 20 and 22 of the carrier platform 12.

In FIG. 1 For example, the support platform 12 assumes a position at the upper end of the first guide rails 28a, 28b while being supported by the first coupling means 20, 22 and the second coupling means 24 on the first links 26 in the vertical direction. The mounting platform 40 takes in FIG. 1 a position at the upper end of the second guide rails 30a, 30b, so that assembly personnel standing on the mounting plate 44 of the mounting platform 40, at the upper end of the second guide rails 30a, 30b may define second links 52, which are formed identically as the first links 26th

Like from the FIGS. 4 and 5 becomes clear, the first connecting members 26 as well as the second connecting members 52 are configured in the illustrated embodiment U-shaped and comprise two legs 54, 56 which are integrally connected to each other via a web 58. The first connecting members 26 surround the mutually facing end portions of two guide rails 28a and 30a or 28b and 30b, where they can be connected by means of connecting screws 60 with the guide rails 28a, 30a and 28b, 30b and with their respective web 54, 56 at the back walls 70 of the guide rails 28a, 28b, 30a, 30b facing the shaft walls 34 and 36, respectively. A U-shape is for the connecting members 26, 52, however, not mandatory, but the connecting members 26, 52 may also have a different shape, as is known in the art, for example, the connecting members may also be designed T-shaped or flat.

The supports 16 and 18 each carry two guide elements in the form of guide shoes 62, 64, which are vertically spaced from each other and each can be brought into engagement with the guide rails. Such guide shoes are known per se to those skilled in the art.

The support plate 14 of the support platform 12 carries on its underside a lifting device in the form of a winch 66, with the aid of elevator components can be raised and lowered. For this purpose, assembly personnel can take a position on the support plate 14.

How out FIG. 4 becomes clear, the second coupling means 24 are plate-shaped and can be placed on the upwardly facing end faces 68 of the connecting members 26 and 52, wherein they rest flat against the back 70 of a guide rail and can be clamped by means of clamping elements 72 with a guide rail , The second coupling means 24 each have on the upper side two inner recesses 74, 75 and two outer recesses 76, 77, which are identical in the form of a trapezoid. On both sides of a guide rail, an inner recess 74 and 75 and an outer recess 76 and 77 are respectively arranged.

The first coupling means 20, 22 of the support platform 12, as well as the first coupling means 48, 50 of the mounting platform 40 each have two identically formed, trapezoidal in cross-section boom 23 which engage positively in their extended working position in recesses of the second coupling means 24. In FIG. 5 a boom 23 of a first coupling device 48 of the mounting platform 40 is shown in its extended position. In their working position, the arms 23 of the first coupling devices 48, 50 of the mounting platform 40 dip into the two inner recesses 74, 75 of the second coupling device 24. The arms 23 of the first coupling devices 20, 22 of the support platform 12 have a greater distance from each other and engage in their working position in the two outer recesses 76, 77 of the second coupling device 24 a.

After the assembly of the second links 52 at the upper end of the second guide rails 30a and 30b, installation personnel occupying a position on the mounting plate 44 of the mounting platform 40 can place third guide rails 78a, 78b on the second guide rails 30, 30b by means of them Set holding members 32 on the shaft walls 34, 36 and connect by means of the second connecting members 52 with the second guide rails 30a, 30b. Subsequently, the arms 23 of the first coupling devices 48, 50 of the mounting platform 40 can be extended into their working position, in which the arms 23, as explained above, engage in the inner recesses 74, 75 of the second coupling devices 24. Thus, the mounting platform 40 via the first coupling means 48, 50 and the associated second coupling means 24 and the second connecting members 52 on the second guide rails 30a, 30b are supported.

Since now the vertical support of the mounting system 10 by means of the mounting platform 40 and the second links 52, the boom 23 of the first coupling means 20, 22 of the support platform 12 can be moved from the first links 26 in their retracted rest position and the support platform 12 can help of the scissor lift table 52 are raised so far in the direction of the mounting platform 40 that the first coupling devices 20, 22 of the carrier platform 12 reach the second coupling devices 24 arranged on the second connecting links 52. Subsequently, the arms 23 of the first coupling devices 20, 22 of the support platform 12 can be extended into its working position in which they dip into the outer recesses 76, 77 of the second coupling devices 24.

In FIG. 2 the mounting system 10 is shown at the transition of the support platform 12 from a position at the upper end of the first guide rails 28a, 28b to the upper end of the second guide rails 30a, 30b.

After the first coupling devices 20, 22 are connected to the second coupling devices 24, which rest on the second connecting links 52, the arms 23 of the first coupling devices 48, 50 of the mounting platform 40 can be moved to their rest position and the mounting platform 40 can by means of scissor lift 42nd be raised again. This is in FIG. 3 shown. In a subsequent assembly step, further guide rails can then be placed on the third guide rails 78a, 78b by means of the mounting platform 40, which can be fastened to the shaft walls 34, 36 by means of holding members and connected to the third guide rails 78a, 78b by means of further connecting members. The assembly process may then be repeated by supporting the mounting platform 40 on the last assembled links and raising the carrier platform 12 from the scissor lift 42.

The mounting system 10 thus enables a crawler-shaped movement of the support platform 12 and the mounting platform 40, wherein both platforms are supported on guide rails, which can be mounted in the shaft 38 by means of the mounting system 10. A building-side support of the support platform 12 and the mounting platform 40 is not required.

In the FIGS. 6, 7 and 8th a second embodiment of the mounting system according to the invention is shown schematically, which is generally designated by the reference numeral 100 and the same as a in FIG. 9 schematically illustrated third embodiment of the mounting system according to the invention is designed substantially identical to that described above with reference to the FIGS. 1 to 5 explained assembly system 10. For identical components are therefore in the FIGS. 6, 7 . 8th and 9 the same reference numerals as in the FIGS. 1 to 5 and with respect to these components, reference is made to the foregoing explanations to avoid repetition.

The mounting system 100 differs from the mounting system 10 only in that the mounting plate 44 of the mounting platform 40 carries a lifting device in the form of a lifting crane 102, which facilitates the mounting of the guide rails in the shaft 38.

Also in the mounting system 100, both the support platform 12 and the mounting platform 40 can be supported on connecting members 26, 52, are connected to each other via the two guide rails 28a, 30a and 28b, 30b end. With the help of guide elements, such as guide shoes 62, 64, the support platform 12 can be guided on the guide rails 28a, 28b, 30a, 30b in the vertical direction, whereas a vertical guidance of the mounting platform 40 can be omitted, as this cantilever with the help of Scherenhubtisches 42 on the carrier platform 12 is held.

In FIG. 9 a third embodiment of a mounting system according to the invention is shown, which is generally designated by the reference numeral 120. Of the mounting systems 10 and 100 described above, the mounting system 120 differs in that the support platform 12 and also the mounting platform 40 are not supported on the guide rails but on the shaft wall. For this purpose, the carrier platform 12 and the mounting platform 40 of the mounting system 120 movable arms 123, which can dive for stationary fixation of the support platform or the mounting platform 40 in niches 123 of the shaft walls 34, 36. This makes it possible to move the mounting system 120 independently of the guide rails. The carrier platform 12 and the mounting platform 40 of the mounting system 120 are supported directly on the shaft walls 34, 36. Alternatively or additionally, it may be provided that the arms 123 of the mounting system 120 for stationary fixation of the support platform 12 and the mounting platform 20 cooperate with support elements which are fixed to the shaft walls 34, 36.
