Description

The subject invention relates to a cable car system for the transport of persons or goods with two pairs of between two end stations, in particular a valley station and a mountain station, extending suspension cables, along which by means of at least one pull rope vehicles are movable, the support cables in the area at least one support bracket Curved in plan view and the pull rope is guided in the region of at least one support post via support rollers.

EP 2 072 367 A discloses a cable car system with a carrying or conveying rope, which runs along a curve. Movable idlers for the pull rope of a straight-running cable car system are from the WO 2012/085883 A known.

In known cable car systems of this kind, the carrying cables are carried along the route by supports, wherein they can extend along bends in the region of the supports. This makes it possible to adjust the course of the cable car system the topographical conditions.
The movement of the vehicles by means of at least one pull rope. In particular, a self-contained pull rope is provided for this purpose, which is guided in the end stations via deflecting disks, of which at least one is driven.

Over the course of the route, the at least one pull rope is guided by carrying rollers. For this purpose, fastened to the respectively associated supporting cables, downwardly projecting rope rider is provided, on which in each case at least one support roller is mounted, from which the traction cable is carried. The pull rope is located approximately midway below the suspension cables. In the areas of supports the pull rope is also guided over support rollers, which are mounted on frame-fixed roller carriers.

Since the traction cable is coupled to the chassis of the vehicle, this has in those areas in which a chassis is located, the result that it is lifted from the carrying rollers located in this area and only when the chassis of these idlers away has again get on these carrying roles. In those areas of the route of the cableway system, in which this runs in a straight line, the traction cable, after the landing gear has moved away from the respective carrier rollers, lowers in the vertical direction, wherein it comes centrally on these support rollers.

In contrast, when the support cables are curved, in the areas of curvatures the pull rope is not only lifted by a vehicle from the support rollers located there, but it is laterally offset from these support rollers, and it remains laterally offset even when it is lowered on these support rollers , As a result, the pull rope does not return to the center of the support rollers, whereby it does not get directly into the rope grooves located on these support rollers. As a result, transverse displacements of the traction cable occur in regions of curvatures on the carrying rollers, as a result of which either the traction cable no longer gets into the grooves of the respective carrier rollers or the traction cable is moved onto the carrier rollers to the grooves, whereby an increased wear of the carrier rollers is caused.

The objective invention is therefore based on the object to avoid these disadvantages. This is inventively achieved by the subject matter of claim 1, wherein at least some of the support rollers located in the region of the at least one support for the at least one traction cable in its position relative to the two support cables are laterally adjustable.

By changing the position of the support rollers in areas of curved support cables that support rollers are adjusted laterally in the same manner as the pull rope, which ensures that the pull rope passes in its lowering approximately centrally on these support rollers, thereby entering the grooves of the Support rollers passes and thus lateral adjustments of the lowered to the support rollers pull rope and thereby caused wear of the support rollers can be avoided.

Preferably, the support rollers are adjustable under the action of a force. In this case, the relevant support roller or the like for the at least one pull rope on a swivel arm. be mounted, which is höhenverschwenkbar about an at least approximately horizontal axis under the action of an adjusting device, in particular a spring. The suspension cables in the area of at least one support on carriers, in particular support plates, rest, on which the pivot arm, on which a support roller is mounted for the at least one pull rope, höhenverschwenkbar.
In particular, supports, in particular support plates, may be fastened to the support, on which support bearings for the suspension cables are located, wherein the pivoting arm is articulated with the support roller mounted thereon on one of the two supports and the other of the two supports is formed with stops for the pivoting arm is.

According to another embodiment, the two supporting cables are in the region of at least one support on a respective carrier, in particular supporting plates, which carriers are connected to each other by an obliquely oriented connecting strut, and is on this connecting strut a under the action of a restoring force, in particular a compression spring, slidable sleeve on which a support roller is mounted. In this case, the displaceable sleeve may be associated with a stop.

Furthermore, the two support ropes in the region of at least one support on each support, in particular support plates, rest, which two carriers are interconnected by a connecting strut, wherein on the connecting strut two steering arms are mounted, to which a carrier is articulated for a support roller, wherein this support is under the action of a restoring force, in particular a compression spring, by means of which it is laterally adjustable relative to the supports for the support cables, in particular the support plates.

Furthermore, one of the two supports, in particular support plates, may be formed with a stop.

According to a further embodiment, supports, in particular vertical support plates, are provided in the region of the at least one support, between which a pivot arm is pivotably mounted on a frame-fixed bolt, on which a support roller is mounted, wherein the pivot arm under the action of a force, in particular a weight or an electric motor, is adjustable from a lower pivot position in an upper pivot position.
In addition, the swivel arm between two attacks can be adjusted in height.

The in the FIG.1 and FIG.1A Cableway system shown has a first end station 1 and a second end station 2, between which two pairs of support cables 3, namely the respectively associated support cables 31, 32 and 33, 34, are located. The support cables 3 are guided in the course of the route of the cable car over supports 4 and supported by them. Furthermore, there is a self-contained pull rope 5 in the cable car system, which is guided in the end stations 1 and 2 via deflecting plates 11 and 21, wherein at least one of these deflection plates 11 is driven. Along the support cables 31 and 32 are by means of the traction cable 5 to this coupled vehicles 6, which are formed with a vehicle cab 60 and with a chassis 61, moved from the first end station 1 to the second end station 2. Along the carrying cables 33 and 34, the vehicles 6 coupled to the traction cable 5 are returned to the first end station 1 again. In the two end stations 1 and 2 guide rails are provided, along which the uncoupled from the traction cable 5 vehicles 6 are moved through the end stations 1 and 2 and moved by a pair of suspension cables 3 on the other pair of suspension cables 3, whereupon they return to the in closed traction cable 5 are coupled.

Like this in 1A is shown, the support cables 3 are curved in the region of the support 4. In the areas of other supports, the support cables 3 can also be curved. This allows the course of the Ropeway system adapted to the topographical conditions. In the rectilinear areas of the cableway system, the two associated support cables 31, 32 are connected by cable riders on which support rollers for the traction cable 5 are mounted. In the areas of the supports 4, in which the support cables 31, 32 rest on support bearings against which they are displaceable, support rollers for the pull cable 5 are also provided, which are mounted on roller carriers, which are fastened to the mutually associated support means for the support cables 3 are.

In FIG.2 is a section of the cable car system shown, with a vehicle 6, the chassis 61 is moved by means of the pull cable 5 along the support cables 3, approximates to a support 4.

In the FIG.3 and FIG.3A is a rope rider 7 of the kind shown, which are located in the straight-line sections of the cable car system. This rope rider 7 consists of a support frame 70, which is clamped by means of two pairs of terminals 71, 72 to the support cables 31, 32. From the support frame 70 protrude vertically down two approximately V-shaped bracket 73, 74, which are in the longitudinal direction of the support cables 31, 32 from each other at a distance and which are interconnected by means of a support frame 75. On the support frame 75, a support roller 8 is mounted for the traction cable 5. Furthermore, located on both sides of the support roller 8 fixed to the support frame 75 cable guide 76. If there is no vehicle 6 in the area of the rope rider 7, the traction cable 5 is in the track 81 of the support roller 8. It is this on the 3a directed.

In the FIG.4 and FIG.4A are a chassis 61 of a coupled to the traction cable 5 vehicle 6 and attached to the support cables 31 and 32 rope rider 7, which is run over by the chassis 61, shown. The chassis 61 is formed with two pairs of wings 62, on each of which a pair of wheels 63 is mounted, wherein two pairs of wheels 63 run along the support cable 31 and the other two pairs of wheels 63 along the support cable 32. The drive 61 of the vehicle 6 is further formed with two associated jaws 64, which are actuated by means of two control rollers 65 against the action of compression springs 66. By means of the jaws 64, the chassis 61 can be clamped to the pull cable 5.

To the chassis 61, a support rod 67 is hinged, at the lower end of the vehicle cab 60 is attached.

Like this from the FIG.4 and FIG.4A it can be seen, the traction cable 5 is lifted when driving over the rope rider 7 by the chassis 61 of the support roller 8. As soon as the chassis 61 has moved away from the cable rider 7, the traction cable 5 descends again, as a result of which it enters the track groove 81 of the carrier roller 8. Since the support cables 3 between the supports 4 are rectilinear, there is no deflection of the traction cable 5, so that, after the trolleys 61 have moved away from the cable carriers 7, they return to the grooves 81 of the carrier rollers 8.

In FIG.5 a section of the cable car system is shown, wherein a vehicle 6 is located on the support 4.
As has been stated above, the supporting cables 3 on the supports 4 can have a curved course. In this case, however, takes place when lifting the traction cable 5 of the supports located on the supports 4 a lateral deflection of the traction cable 5 relative to the support cables 3 as well as against the idlers, which in the subsequent lowering of the traction cable 5 this does not get into the rope groove of the respective carrying role.

In 5a a roller carrier 7a of the type is shown, which is located on a support 4 and by which it is achieved that when lowering the pull cable 5 this comes directly into the rope groove of the respective support roller. On the frame 4, two vertically oriented I-shaped support plates 71a, 72a attached to the upper ends of which are made of bronze support bearing 31a, 32a for the support cables 31, 32 are located. Between the vertical support plates 71a, 72a is a pivot arm 73a, on which a support roller 8a is mounted for the pull cable 5. The pivot arm 73a is mounted at one end on the vertical support plate 72a höhenverschwenkbar about a pin 70a. At the other vertical support plate 71a, two stops 76a are provided by which the Höhenverschwenkbarkeit the pivot arm 73a is limited. Furthermore, a tension spring 77a is articulated to the vertical support plate 71a and the pivot arm 73a, through which the pivot arm 73a is loaded so that it is pivoted up.

Along the route, the traction cable 5 rests on the carrying roller 8a mounted on the pivoting arm 73a, being in the running groove 81a. As long as the traction cable 5 has not been lifted off the carrier roller 8a due to the fact that the chassis 61 of the vehicle 6 is not in the region of one of the roller carriers 7a, the tension spring 77a does not take effect due to the load imposed by the traction cable 5. However, as soon as the chassis 61 approaches a roller carrier 7a, the traction cable 5 is lifted off the carrier roller 8a.

Hereinafter, the positions of the traction cable 5 at different positions of the vehicle 6 with respect to one of the supporting roller 8a mounted on the support 4 will be explained in the case that the course of the traction cables 3 is curved as shown in FIG 1A is shown.

According to the FIG.2 is the vehicle 6 of those support rollers 8a, which are mounted on the support 4, in such a large distance that the pull cable 5 is not lifted from these support rollers 8a. This location is off 5a seen.
According to FIG.5 is the chassis 61 of the vehicle 6 on the support 4 in the region of a support roller 8a. Like this 5 b it can be seen, while the pull cable 5 is lifted from the support roller 8a, whereby the pivot arm 73a has been adjusted under the action of the tension spring 76a in its upper pivot position.

Like this from the FIG.6 and FIG.6A as well as from the FIG.7 and FIG.7A it can be seen, this is true even if the chassis 61 of the vehicle 6 is above the roller carrier 7a and if the chassis 61 has indeed run over the roller carrier 7a, but the chassis 61 is still in the area of this roller carrier 7a.

Since the support cables 31, 32 extend in the region of the support 4 in a curvature, this has the consequence that the pull cable 5 is deflected in the direction of the center of the curvature, namely that it is adjusted laterally relative to the support cables 3 and with respect to the associated support roller 8a , Due to the fact that the traction cable 5 is lifted off the carrying roller 8a, under the action of the tension spring 77a, the pivoting arm 73a and with it the carrying roller 8a are adjusted such that that region of the carrying roller 8a which faces the traction cable 5 likewise points in the direction of the center point the curvature is adjusted, whereby the raceway 81a of the support roller 8a is located approximately below the traction cable 5.

In 8A a section of the cable car system is shown, wherein the vehicle 6 has moved so far away from the carrying roller 8a that the pull rope 5 descends again onto the carrying roller 8a. As a result, the pull rope 5, although it has been deflected laterally due to the curved course of the support cables 3, directly into the roller 81a of the support roller 8a. As a result, the pivot arm 73a due to its load by the pull cable 5 is adjusted against the action of the tension spring 77a from the upper pivot position back into the lower pivot position, as in 8B is shown.

Due to the pivotability of the support rollers 8a for the traction cable 5 in areas of a curved course of the suspension cables 3 is thus achieved that with respect to the lateral deflection of the traction cable 5, the position of the support rollers 8a is adapted to the position of the traction cable 5, thereby ensuring that the Pulling cable 5 when it is lowered directly into the grooves 81a entered. As a result, shear movements of the traction cable 5 with respect to the support rollers 8a and thereby increased wear of the support rollers 8a are avoided.

In the FIG.9 and FIG.9A shows a second embodiment of a roller support 7a according to the invention with a relation to the support cables 31a, 32a laterally and height-adjustable support roller 8a. The two vertical support plates 71a and 72a are connected to each other by a obliquely oriented strut 91 fastened thereto, a sleeve 92 being located on this strut 91 which is displaceable under the action of a compression spring 93 in the direction of the arrow A and on which Support roller 8 is mounted. The sleeve 91 is associated with a stop 91a.

As long as the traction cable 5 is guided in the raceway groove 81a, as is apparent FIG.9 it can be seen, the compression spring 93 is in its tensioned position. Therefore, as soon as the traction cable 5 is raised, since the carrier roller 8a is run over by a chassis 61, the sleeve 92 is displaced in the direction of the arrow A under the action of the compression spring 93, as is apparent from FIG 9A is apparent. As a result, the support roller 8a of the lateral deflection of the Traction cables 5 tracked. As soon as the traction cable 5 descends, it passes directly into the track groove 81a. In further consequence, the sleeve 92 is moved back due to the force exerted by the pull cable 5 load against the direction of the arrow A, whereby the compression spring 93 is in turn tensioned.

In the FIG.10 and FIG.10A a third embodiment of a roller carrier 7a according to the invention is shown. In this case, a strut 97 is fixed to the two vertical support plates 71a, 72a, to which two steering arms 96 are articulated. Of the two steering arms 96, a carrier 94 is supported, on which the support roller 8a is mounted and which is under the action of a compression spring 95. Furthermore, a stop 98 is provided on the vertical support plate 72a, to which the carrier 94 comes into contact with its lateral adjustment, whereby its adjusting movement is limited.

In the FIG.11 and FIG.11A a fourth embodiment of a roller carrier 7a according to the invention is shown. In this case, the support roller 8a is mounted on a pivot arm 101, which is mounted on a frame-fixed pin 102. One of the two ends of the pivot arm 101 stops 103 are assigned. At its other end, a weight 104 is attached to the pivot arm 101.
As long as the traction cable 5 is located on the carrying roller 8a, the pivoting arm 101 is against the action of the weight 104 in its lower pivot position, which in 11A is shown.
As soon as the traction cable 5 is lifted off the carrying roller 8a, the pivoting arm 101 is adjusted under the action of the weight 104 into its upper pivoting position, whereby the carrying roller 8a is slightly raised and displaced laterally, as shown in FIG 11A is shown.

In the FIG.12 and FIG.12A a fifth embodiment of a roller carrier 7a is shown, which differs from the fourth embodiment according to the FIG.11 and FIG.11A differs in that the adjusting force for adjusting the pivot arm 101 is not applied by a weight, but rather by an electric motor 105.

The operation of the adjustability of the support roller 8a in the embodiments of the roller carrier according to the FIG.10 and FIG.10A . FIG.11 and FIG.11A or. FIG.12 and FIG.12A corresponds to that mode of action, which above with reference to the embodiment according to the FIG.9 and FIG.9A is explained.
