Description

The invention relates to an elevator, in particular an external elevator.

Exterior lifts are used, for example, on construction sites of building construction to transport people and material in the upper floors of the building to be built or renovated.

Such external elevators regularly have a guide which is fixed to a wall of the building and extends in the vertical direction. The guide consists of one or two mast towers on which / which a car is movably arranged. The car serves to accommodate the persons to be transported or the goods to be transported.

The mast towers thus serve to guide the movement of the car, which may also represent a part of the drive train. As a rule, for this purpose at least one of the mast towers is provided with at least one toothed rack which extends in the longitudinal axial direction of the guide and in which a pinion of an electric traction drive engages. In such elevators, the travel drive is thus accommodated in the area of the car and is thus moved along with the car.

Due to the not inconsiderable performance of the drive of such lifts are These are supplied with electrical energy via cables. In a car drive carried along with the car, the cable must therefore be of sufficient length to allow the car to move to its highest position on the guide. However, many elevators reach heights of up to several hundred meters, which places great demands on the storage and management of the cable. In particular, the cable must be safely stored in the area of a ground station of the elevator when the car is in a position relatively far down the guide. In some cases, several hundred meters of cable must be stored in a space-saving manner and in a manner that makes possible a problem-free lengthening or shortening of the cable section connecting the ground station to the car. Such lengthening and shortening must be possible in a variety of cycles, without damaging the cable and without the cable getting caught or intertwined. In addition, an uncontrolled cable movement should be avoided, especially in the area of the ground station of the elevator. In many cases, the cables are simply more or less uniformly stored in a round, open-topped cable container, also called a cable tray.

It is also known, especially in elevators with a relatively high guide, to use so-called cable cars, which are also guided on the guide and have a deflection roller over which the cable is guided. The coming of the ground station section of the cable is fixed at about half the height of the guide in a so-called central feed. The section between the center feeder and the car has a length that allows reaching the highest and lowest hold positions on the car's route. The depending on the respective distance between the fixation and the car excess portion of the cable is guided in a loop over the pulley of the cable cart. The cable car is also guided on the guide of the elevator, this is always below the car and follows its movement at half speed. The cable car is in the area of the car when it is in the ground station and at about half the height of the guide when the car has reached its highest position on the guide.

A structure of such a lift is associated with a considerable effort. As a rule, starting from a ground station, the guidance is successively extended by attaching individual guide segments, wherein the guide segments in the car are transported to the upper end of the already constructed guide section and set from the car to this end.

A problem with such a construction is the guidance of the cable during construction. The cable must in fact follow the up-and-down movement of the car, this movement taking place by the successive extension of the guidance over increasing distances. It is known to store the respectively unneeded cable length in the area of the ground station, which, however, entails a constant winding and unwinding or layering and stripping of the cable. This increases the wear of the cable.

This disadvantage can be reduced in elevators with cable cars by early use of the cable cart. However, this requires a permanent transfer of funds for the extension of the management. However, since at the same time increase the travel distances of the car, it is regularly required to solve the fixed in the central feed cable to track from the storage at the ground station and fix it in a new location in the central feed. The associated effort is significant.

In order to avoid this, it is known to supply the drive of the car, at least during a section of the bodywork, by means of a so-called assembly cable, which is not guided over the cable car and with regard to its construction and design for the load resulting from the multiple application. and unrolling or coating and stripping results, is suitable.

Based on this prior art, the invention was based on the object of specifying an improved in particular with regard to its construction ability elevator.

This object is achieved by a lift according to independent claim 1. A method for constructing such a lift is the subject of independent claim 15. Advantageous embodiments of the elevator according to the invention and the method according to the invention are the subject of the respective dependent claims and will become apparent from the following description of the invention.

A generic elevator comprising a guide, a ground station, a car guided on the guide, a cable guided along the guide to the car, in particular flat cable, which is guided via a cable trolley with a deflection device following a movement of the car, and a central feed , which serves for the clamping fixation of the cable and can be fixed to the guide, according to the invention further developed in that both at the ground station and on the car a storage device for supporting a portion of the cable (hereinafter cable section) is provided.

Such an elevator allows a structure according to a method in which the guide is successively extended by attaching individual guide segments to a total length, wherein the central feed, following the extension of the guide, is fastened at different heights to the guide. In this case, the invention provides that a required to increase the center feed extension of the guided between the central feed and the ground station cable section is made up from the storage facility of the ground station and made necessary due to the extension of the extension of the guided over the cable car cable section from the storage facility of the car becomes.

As a result of the embodiment of an elevator according to the invention, a section of the cable can be stored both in the area of the ground station and on the car (which are preferably of essentially the same length) during construction. Furthermore, the center feed can already be fixed at the beginning of the construction at that point of the cable, at which this is to fix the cable during operation. To simplify this, the cable may preferably be provided with a length scale (eg printed). The extension of the cable section between the ground station and the central feeder, which is necessary because of the displacement of the central feed-in, can be achieved by tracing from the Store the cable in the area of the ground station. The extension of the guided over the cable car, thus extending between the car and the central feed cable section that is to enable the successive in the construction of extending driving distance of the car, however, can be realized by catching up from the storage of the cable to the car. Thus, a structure of a generic elevator can be done without the cable in the area of the ground station with each up-and-down movement of the car up and unrolled or stripped and stripped and without a constant catching up in the central feed would be necessary , The expense associated with the construction of the elevator is thus comparatively low.

Dismantling of the elevator according to the invention is possible in a corresponding manner. The increasingly shortened cable section between the center feed and the ground station can be stored in the storage facility of the ground station, while the increasingly shorter required length of the process of the car enabling, guided over the cable car cable section is compensated by a storage in the storage device of the car.

An advantageous possibility to store the cable sections in the storage device of the ground station and / or the car may be to stack them in the form of 8ern ("aft") or simple loops one above the other. This can be a space-saving and cable-friendly storage option. Significant advantages of this type of storage on the one hand are the relatively large length of the cable section deposited in the individual layers and, on the other hand, the advantageous handling during stripping during the construction of the elevator. An aft bearing is particularly useful when using a round cable (cable with a round, in particular circular cross section) to avoid the generation of a twist of the cable during stripping. In the preferably provided use of a flat cable in addition to a storage in aft and a storage in simple loops, ie always the same sense of winding (in the turning points), take place because flat cables are not prone to twisting and thus the changing in storage in aft winding sense ( in the turning points) is not necessary.

For a simple and dimensionally stable storage in aft or loops, in particular lying i. horizontally disposed aft or loops, the storage devices may include storage rods around which the corresponding cable portion is laid to form the individual figure-of-eight or loop layers. For example, (at least) two bearing rods may be provided for storage in "straight" aft or loops.

A particularly good utilization of the storage area available in the storage facility can be achieved in that the storage facility of the ground station and / or the car supports the respective cable section in angled aft or loops (at their intersection points). For this purpose, the storage device can have (for example) (at least) three storage rods that are not lying in a straight line.

In a preferred embodiment of the elevator according to the invention can be provided that the storage device of the car is arranged on the roof. As a result, the area available there can be used advantageously. In addition, such an arrangement of the storage device, in contrast to a storage on one or more of the side walls of the car, which is also possible in principle, have the advantage that the storage device does not increase the base of the car. Thus, for example, this can not come into collision with a defense of the ground station.

In particular, in a arranged on the roof of the car storage device can advantageously be provided that the corresponding cable section is mounted in angled aft.

In order to simplify the repeated heightening of the central feed during the construction of the elevator according to the invention, provision can be made for the central feed to have fastening means, such as an eyelet, for receiving a lifting element (eg a hook). To increase the amount of funds fed in, because of the fixation of funds in one place of the Cable is connected to a retrieval of cable from the storage device of the ground station, thus can be done in a simple manner by means of, for example, a crane (including any winches are understood) or by means of the car itself.

It can be provided that the center feed is set higher with each setting of a guide segment. This can dispense with the arrangement of a cable guide above the center feed. This can then advantageously make it possible to offset the central feed by means of the car.

In a further preferred embodiment of the elevator according to the invention, a cable holder arranged on the car or moving along with it can be provided, in which the cable can be fixed. The cable holder can, if the cable is fixed therein, primarily serve as a strain relief for the connection of the cable to the drive arranged on the car. By the cable holder can thus be prevented that the weight of the guided over the cable car cable section and the weight of the cable cart acts on the formed, for example in the form of a connector connection. In addition, the cable holder can guide the cable so that it runs at a sufficient distance from the car. As a result, contact of the cable with the car during operation can be avoided.

Due to the solvability of the fixation of the cable in the cable holder can be ensured that in the context of the construction of the elevator according to the invention, cables can be made up of the arranged on the car storage device.

In a preferred embodiment of the cable holder this may have a clamping device for fixing the cable. This can in particular be designed such that the clamping action is self-reinforcing in cooperation with the weight of the guided over the cable car cable section. Alternatively or additionally, it may be provided that the clamping device (in its clamping position) is spring-loaded.

In a further preferred embodiment of the elevator according to the invention, a pulling device can be provided, in which the cable can be fixed and has the means for moving (the pulling device) along or for fixing to the guide. The pulling device can be used in particular if the central feed at the beginning of the construction is not at the correct, i. final location on the cable has been fixed and therefore the center feed is to be fixed at a different point of the cable during assembly. Then the center feed can be fixed to the guide and the cable pulled up by means of the pulling device, i. be retrieved from the storage facility of the ground station, without the central feed is moved. Likewise, it is possible to fix the cable by means of the pulling device to the guide and to put the dissolved from the cable center feed to the desired location of the cable.

The means for moving the pulling device can be designed in particular in the form of fastening means, for example in the form of an eyelet, for receiving a lifting element (for example crane hooks). Thus, the tracking of the cable can be easily accomplished e.g. done by means of a crane.

Preferably, the pulling device may comprise a clamping device for the cable, which is self-reinforcing in cooperation with the weight of the guided along the guide cable portion.

In a further preferred embodiment of the elevator according to the invention can be provided that the cable cart is designed so that the cable can be introduced laterally in this. This allows a subsequent installation of the cable cart done without a free end of the cable must be available. For this purpose, the cable trolley have a deflecting element, in particular a deflection roller, which is arranged between two side parts, wherein a side part of the deflecting element removable, for example, hinged, is to allow lateral insertion of the cable.

Preferably, the elevator according to the invention can one or more, then arranged at different heights, on the guide (also) below the

Central feed have fixed cable guides, in which the extending between the ground station and the center feed cable section is guided. In this case, the cable guides can advantageously be designed so that they do not fix the cable (but only limit its lateral freedom of movement) to allow retrieval during construction.

Preferably, the cable guide may include a guide portion for the cable portion extending between the ground station and the center feed, and one or two separate guide portions for the cable portion routed over the cable carriage. By separating the individual cable sections, contact between them can be prevented as much as possible.

The subject matters of the dependent claims 5 to 14 represent advantageous embodiments for particular lifts according to the invention, but are also suitable for improving any generic elevators, so that they are independent of the objects of the independent claims.

In the drawings, the cable of the elevator for a better overview is not or only partially shown.

The elevator shown in the drawings comprises a ground station 1 with a barrier 2, from which a guide 3 extends in the vertical direction. The guide 3 consists of individual guide segments 4, which are interconnected. The guide segments 4 are constructed as a framework of interconnected struts, wherein four (alternatively: two) parallel vertical struts are provided, which are interconnected via a plurality of transverse struts. The cross section of the guide 3 is quadrangular, wherein the vertical struts have a circular cross-section.

On one of the sides of the guide 3, a car 5 is movably guided. These are a plurality of roller guides provided, which roll on two adjacent, serving as guide rails vertical struts of the guide 3.

The car 5 further comprises a travel drive with a plurality of electric motors 6, the drive pinion engage in a rack 8, which runs parallel to the vertical struts of the guide 3. By operation of the electric motors 6, the car 5 can be moved along the guide 3.

The electric motors 6 are supplied via a (flat) cable 9 with electrical energy. A cable section extends between a arranged on the roof of the car 5 switch box 10 and a deflection 11 of a cable cart 12 and between the deflector 11 and a central feed 13, which after the complete construction of the elevator at about half (total) height of Guide 3 is fixed to this. Starting from the central feed 13, a further cable section is guided along the guide 3 to the ground station 1 and connected there to an electrical energy source.

The cable carriage 12 has, in addition to the deflection device 11, a guide device 17, via which the deflection device 11 is guided on the guide 3. During a movement of the car 5, the cable carriage 12 moves in the same direction, but - due to the simple deflection - with only half the speed.

In the area of the ground station 1, a storage device 14 is provided for the storage of a cable section, in particular during the construction and dismantling of the elevator. The storage device 14 comprises a housing with an openable lid. Within the housing, two storage rods 15 are provided near the longitudinal ends (cf. Fig. 4 ). Around this, the cable section to be stored is laid in several layers, each of which forms an eight, (cf. Fig. 10 ).

Furthermore, a storage device 14 is provided on the roof of the car 5, in which, in particular during the construction and dismantling of the elevator, a cable section can be stored. It is envisaged that the corresponding Cable section in multiple layers, each of which forms an angled eight to wrap around a total of three storage rods 15, as shown in the Fig. 10 is shown schematically. Two or three security rods 16, which are arranged adjacent to the three storage rods 15, thereby to prevent a slipping of the cable 9 over the edge of the car 5.

The elevator is constructed by successively placing individual guide segments 4 on the upper, free end of the already existing guide 3 and attached thereto. From a certain height of the guide 3, this takes place from the car 5 already guided on the existing guide 3, in particular from the roof of the car 5. In this case, a few guide segments 4 can be stored within the car 5 and pulled over a roof opening on the roof (for example by means of a winch). However, if these guide segments 4 are installed, the car 5 must be moved into the ground station 1 in order to receive new guide segments 4. Then the car 5 can be moved again to the upper end of the guide 3.

According to the invention, at the beginning of the construction, the center feed 13 is fastened to the cable 9 at the location of the cable 9 at which it is also provided in the final operation of the elevator, ie after reaching the full height of the guide 3. As can be seen in particular from the Fig. 5 results, the center feed 13 for a clamping plate 18 which is guided obliquely with respect to a clamping surface in a guide 19. The cable 9 is guided between the clamping plate 18 and the clamping surface and thereby clamped. The oblique guide of the clamping plate 18 is selected such that an increasing weight of the guided from the central feed 13 to the ground station 1 cable section leads to an increase of the clamping pressure. The central feed 13 also forms a tubular deflection device 20, via which the cable 9 is deflected. Furthermore, a fastening device 21 is provided, by means of which the central feed 13 can be fastened to the guide 3 at different positions. The fastening device 21 may be designed in particular as a simple hook, so that the attachment to the guide 3 is effected by hanging.

At the beginning of the construction, a large part of the lower cable section (starting from the central infeed 13) is stored in the storage device 14 of the ground station 1 and a large part of the upper cable section is stored in the storage device 14 of the car 5. During construction, the center feed 13, following the increasing extension of the lead 3, is regularly raised higher. This extends the lower cable section, which is made possible by a retrieval of the cable 9 from the storage device 14 of the ground station 1. However, as the height of the guide 3 increases, so does the travel path which the car 5 must regularly cover between the ground station 1 and the upper end of the guide 3. In order to make this possible, cable 9 from the storage device 14 of the elevator car 5 is retrieved successively, following the extension of the guide 3. After the complete construction of the elevator, depending on the length of the cable 9 used, a relevant length of the cable 9 can still be kept in one or both storage devices 14 or the respective cable section has been completely removed from the storage devices.

Since the central feed 13 is loaded at least with the weight of the cable section extending between it and the ground station 1, a manual displacement of the center feed 13 is no longer possible from a certain height. Rather, it is then provided to offset the central feed 13 by means of a crane (not shown) or the car 5 itself. For this purpose, a crane hook or a connecting means of the car 5 engage in the passage formed by the tubular deflecting device 20 and thereby the center feed 13 are added.

In the area of the car 5, the cable 9 is guided via a cable holder 22 connected to the car 5. This comprises a deflection device 23, in which a clamping device is integrated. By means of the clamping device, the cable 9 is fixable. The cable holder 22 serves primarily to form a strain relief for the connection of the cable 9 to the control box 10. The weight of the extending between the cable holder 22 and the central feed 13 cable section and the cable cart 12 is supported by the cable holder 22. The preferably designed as a connector connection of the cable 9 to the control box 10 is thus largely unloaded.

The clamping device of the cable holder 22 is effected by a clamping plate 24 of the deflection device 23 in cooperation with a clamping surface of a support structure 25 of the cable holder 22. Between the clamping plate 24 and the clamping surface, the cable 9 is guided, wherein the clamping of the cable 9 is effected by a rotatable mounting within the deflection device 23 on the support structure 25. In this case, the bearing of the deflection device 23 is selected on the support structure 25 so that the weight-induced train, which is exerted by the guided over the cable carriage 12 cable section on the deflection device 23 of the cable holder 22, to an approximation of the clamping plate 24 to the clamping surface and thus a self-reinforcing clamping action leads. In addition, a spring element 7 is provided, which loads the rotatable mounting so that the clamping action is supported.

To release the cable 9 from the storage device 14 of the car 5, the clamping action of the cable holder 22 must be temporarily canceled or reduced. For this purpose, the deflecting device 23 is loaded in the direction of rotation which is opposite to that direction of rotation in which the deflecting device 23 is loaded by the weight of the cable section and the spring preload. This counteracting can be effected in particular by means of a crane or a lifting device (for example cable winch) fastened to the car 5, which acts on a connecting bolt 26 of the deflecting device 23.

The cable car 12 of the elevator is designed so that an insertion of the cable 9 from the side (relative to the deflection 11) is possible. The deflection device 11 of the cable cart 12 comprises a deflection roller 27 and a guide roller 28, both of which are partially wrapped by the cable 9. In order to enable the lateral introduction of the cable 9 in the cable carriage 12, the guide roller 27 and the guide roller 28 are rotatably mounted on one side on a first side part 29 of the deflecting device 11. A second side part 30 is pivotally integrated in the cable carriage 12 and allows in the open state (see. Fig. 6 On the other hand, in the closed state, in which this second side part 30 is arranged at a short distance next to the deflection roller 27 and the guide roller 28, this prevents the cable 9 from jumping off the guide roller 27 and the guide roller 28th

During the construction of the elevator, it may be necessary to change the position of the center feed 13 on the cable 9. In this case, a traction device 31 can be used, which in the Fig. 9 is shown in detail. The traction device 31 comprises a clamping device with a clamping plate 32 which is axially movably mounted in a guide of a base plate 33 of the clamping device within limits. The guide is inclined to the base plate aligned. This ensures that a movement of the clamping plate 32 relative to the base plate 33 down, ie in the direction of the ground station 1, to a reduction of the gap formed between them, in which the cable 9 is guided leads. As a result, the cable 9 is clamped. The clamping action of the clamping device is carried out self-reinforcing by the weight of the cable section located under the pulling device 31, the cable 9 down and thereby, by acting between the cable 9 and the clamping plate 32 friction, the clamping plate 32 pulls down. The friction between the cable 9 and the clamping plate 32 and thus the clamping action increases with increasing weight of the cable.

If the position of the center feed 13 on the cable 9 is now to be changed, the pulling device 31 is used. By means of this, the position of the cable section can be secured or changed while the clamping device of the central feed 13 is released. For this purpose, the pulling device 31 can be fastened to the guide 3 and the central feed 13 can be moved relative to the cable 9. However, it is also possible to leave the central infeed 13 stationary on the guide 3 and to raise or lower the cable 9 by means of the traction device 31. This can be done for example by means of a crane whose hook engages in an eyelet 34 of the base plate 33.

The elevator still further comprises a plurality of cable guides 36, which are fastened to the guide 3 at different heights. The cable guides 36 serve to guide the individual cable sections disposed between the cable holder 22 and the ground station 1. This is a swinging of these cable sections due to wind and the movement of the car 5 is restricted become. The cable guides 36 include a support structure 37 that twice forms three guide portions which are structurally separated from one another. A first guide section 38 serves to guide the cable section extending from the central infeed 13 to the ground station 1. This first guide region 38 is separated by a transverse strut of the support structure 37 from a second guide region 39, which serves to guide the cable section extending from the central feed 13 to the cable carriage 12. The second guide region 39 is separated by elastic webs 40 (made of elastomer) from a third guide region 41, which serves to guide the cable section extending from the cable carriage 12 to the cable holder 22.

Depending on the position of the respective cable guide 36 on the guide 3 and the position of the cable cart 12, the cable is not guided in all guide areas 38, 39, 41 of the individual cable guides 36.

Lateral openings of the first guide region 38 are also closed by means of elastic webs 40. By a deformation of these webs 40 can then be introduced from the side without substantial effort, the corresponding cable section. Thus, the cable guides 36 can be easily assembled to the guide 3 successively during the construction of the elevator.

The front openings of the third guide region 41 are also closed by means of elastic webs 40. These and the webs 40 arranged between the second guide region 39 and the third guide region 41 ensure that the respective cable section remains in the provided guide region 39, 41, but at the same time the deflection device 11 of the cable trolley 12 can pass through it, the webs 40 being elastic be deformed.

The cable 9 comprises within a protective sheath several strands for the transmission of the electrical supply energy and a plurality of control lines for the transmission of control signals. To protect these strands and control lines, they may have a common or each individual, enclosing strain reliefs, for example in the form of Aramidgeflechts. These Embodiment in connection with the training as a flat cable allows comparatively small bending radii for the cable. 9

In the FIGS. 11 and 12 Alternative embodiments of the central feed 13 are shown. These differ from the central feed 13 according to the Fig. 5 on the one hand that for the connection of two separate cable sections, the led to the ground station cable section and guided over the cable cart 12 cable section. For this purpose, these means feeds to a connecting device 42, which may form, for example, two connectors, in which the ends of the cable sections with corresponding mating connectors are inserted. In the connection device, the strands and signal lines located in the cable sections are thus electrically connected.

Furthermore, the differ in the FIGS. 11 and 12 shown Mitteleinspeisungen 13 of the previously described central feed 13 in the manner of fixing the cable sections, which takes place here by means of screws fixed clamping plates 43. If, as shown, the cable 9 are divided into two separate cable sections, a clamping plate 43 is provided for each cable section.

The in the Fig. 12 shown center feed 13 differs in terms of the cable used for the guided to the ground station cable section. This is in the form of a round cable, while for the guided over the cable carriage 12 cable section, as in the embodiment according to the Fig. 11 for both cable sections, a flat cable is used.
