Description

The invention relates, on the one hand, to a rescue vehicle for the transport vehicles of a cable car, with a carriage conveyed on at least one support rope and at least one traction rope, with a salvage basket and with a hanger which is pivotally mounted on the drive and on which the salvage basket hangs below, the salvage basket opposite Drive with a traction device from a driving position to a salvage position can be lowered or raised.

On the other hand, the invention relates to a rescue vehicle for the transport vehicles of a cable car, with a hanger which is pivotally mounted on at least one carrying pull rope and on which a rescue basket hangs at the bottom, the rescue basket being moved from a driving position to a pulling device with respect to its reception on the carrying pull rope Salvage position can be lowered or raised.

According to international standards, cable cars are to be equipped with an emergency vehicle if an area is difficult to walk on, on which the passengers cannot be roped down. Thanks to the high level of operational safety achieved by cable cars today, the recovery vehicles are practically almost unused facilities, since such emergencies generally do not occur. However, the rescue vehicles must always be available for use in accordance with the regulations for emergencies and an annual inspection of the vehicles is provided, in which their operational readiness and functionality is determined and approved.

In a known recovery vehicle with the features mentioned above, which is provided for a cable car with two suspension cables for the transport vehicle, on which the recovery vehicle is also conveyed, the hanger consists of several square tubes articulated at their ends. The upper square tube hangs on Undercarriage, the salvage cage is firmly attached to the lower square tube and can be brought to the required height in several stages with a cable pulling device to the transport vehicle and locked on the square tube. The plurality of joints are designed as locking joints which snap into place between the square tubes. The well-known recovery vehicle is parked in the mountain station. Since the extended hanger is too long with its salvage basket reaching below the platform, the entire salvage vehicle with the drive is removed from the carrying cables and stored in a storage space at the mountain station. The salvage basket is removed from the hanger, the hanger can be folded up in the locking joints and the square tubes fastened to each other next to each other. Removing the recovery vehicle from the suspension cables or putting it back on the suspension cables until it is ready for operation takes a long time and is also a very dangerous matter.

In contrast, the task is to be solved to park the entire salvage vehicle, i.e. drive with suspension including salvage basket and pulling device, in a very confined space and to keep it fully functional and ready for use.

This object is achieved according to the invention with the features that the hanger consists of several traction means, preferably wire ropes, on which the traction means of the traction device acts.

The multiple wire ropes of the suspension, alternatively chains can be provided, form a (statically determined) truss, the tension rods of which consist of traction means; the clamping points or deflections of the traction means are the joints of the framework. The half-timbered construction gives the hanger according to the invention the necessary stability against pendulum movements around the three axes of the spatial coordinate system. Instead of deflections, fixed fixings of the suspension cables can also be provided.

The rescue vehicle according to the invention is therefore resistant to disturbances during driving when driving over supports and very stable against wind influences, since it has only one, but necessary, joint in which pendulum movements are possible, through which the hanger, including the salvage basket, adapts to the different inclinations on the conveyor line. Because of the flexible half-timbered construction, the drive, hangers and salvage basket of the salvage vehicle according to the invention can be contracted while slackening the traction means of the hangers.

In order to lower the recovery vehicle according to the invention from the driving position, in which its length is such that it can be easily extended from the mountain station and conveyed to the transport vehicle, into the recovery position, in which it is set up at the required altitude for the transport vehicle, a traction device is provided, as is known for example from DE 36 04 365 C2, which acts on the taut traction means of the hanger.

In the invention, the lane can consist of a support cable or two support cables and have a separate pull cable, or two of them. The pull rope for the recovery vehicle can belong to a winch or be guided all the way round. The lane of the recovery vehicle can also be the lane of the transport vehicle, for example in the case of a cable car; however, it is also possible to set up a separate lane only for the recovery vehicle between the two lanes for the transport vehicles, for example in the case of a cable car, in which case the recovery vehicle can also convey into the valley station.

In the invention, the support rope can also be a pull rope; in this case, the suspension cable has a rotating cable drive and in turn a separate lane is set up only for the recovery vehicle between the two lanes for the transport vehicles; two carrying cables can also be provided.

For reasons of stability, at least one three-point suspension is provided on the hanger. Preferably, the invention has a four-point suspension, consisting of four equally long wire ropes, between an upper and a lower crossbar stretched, each attack on an upper corner of the salvage basket and from there to the cable pulling device. This inventive design of the truss gives the hanger together with the salvage basket high stability against tipping about one of the two horizontal axes with asymmetrical loading.

A particularly stable hanger with additional struts results in the invention if the four wire cables are each clamped at one end at the corner point of the lower crossmember, deflected at a corner point of the upper crossbar and attack at the opposite corner point of the salvage cage.

In the simplest arrangement, the four wire cables of the hanger are guided on the load hooks of the cable pulling device arranged in the center of the recovery cage, which acts with its pulling rope on the lower crossbar of the hanger. In an advantageous further development, the four wire ropes in the invention are unwound or wound up by a rope drum which is accommodated in the bottom of the recovery cage and accordingly has multiple grooves and on which they engage in the same direction of rotation, and the pulling rope of the rope pulling device engages in a further groove of the rope drum in the opposite direction a. The salvage basket is therefore free of hanging ropes. In the salvage position, the cable drum is locked on the ground.

In an advantageous development of the invention, stops are provided on the recovery vehicle to limit the total stroke when lifting or lowering the recovery basket on the cable drum, which cooperate with a stop on the bottom of the recovery basket and permit approximately one full rotation of the cable drum.

In yet another embodiment of the invention, two bolts in pin holes on the bottom of the salvage basket can be repositioned to limit the partial stroke when lifting or lowering the salvage basket, strike the spokes of the cable drum and enable gradual lowering or lifting of the salvage basket.

The rescue vehicle, which is conveyed in the driving position to the mountain station, can be placed under another cable pulling device Slacken the slack in the sling in the direction of the drive from the driving position into a parking position. The second cable pull device always remains in the top station, is hung there for parking the recovery vehicle on the upper crossbar of the suspension and attacks with four pull cables at the corners on the bottom of the recovery basket; it remains in engagement in the parked recovery vehicle.

The drive 2 shown is intended for a lane consisting of two suspension cables. 1b it has a rectangular frame 2 1. At the four corners of the frame 2 1 2₂ wheels are attached, which roll on the two cables of a cable car. In the case of a single cable car, at least two running wheels are provided on the running gear for stable guidance on the standing cable. With the frame 2 ₁ a triangular suspension 2 ₃ is firmly connected in the side view, at the lower corner of which a hinge 2 ₃ 1 is arranged for pivotally accommodating the hanger 4 on the drive 2.

The hanger 4 consists of an upper 4₃₁ and a lower cross member 4₂ and four equally long wire ropes 4₁. Both trusses 4₂ and 4₃₁ have rectangular frames. The upper cross member 4₃₁ is extended with a vertical rod 4₃₂ upwards and at the end of its extension in the joint 2₃₁ on the drive 2nd articulated. Between the two trusses 4₂ and 43 and the salvage basket 3, the four wire ropes 4₁ are stretched:

Each wire rope 4₁ is attached at one end to a corner point of the rectangular frame of the lower cross member 4₂, is deflected at the diagonally opposite corner point of the upper cross member 4₃₁ and led to the associated corner point of the lower cross member 4₂. There it can be deflected and attack the associated upper corner point of the recovery cage 3 and in turn deflected by means of a roller 3 1 arranged there to be continued to a cable pulling device, not shown in FIG.

In Figure 2 , the upper pulleys 3₁ in the salvage position of the recovery vehicle 1 according to Fig.2b with 3₁₁ to 3₁₄ marked; they lead the four suspension cables 4₁₁ to 4₁₄ to the lower guide rollers 3₂, which are marked with 3₂₁ to 3₂₄. The lower guide rollers 3₂ steer the suspension cables 4₁ from the vertical to the horizontal and guide them to a cable drum 6 housed in the bottom of the recovery basket 3, on which they are wound in the same direction. In Fig.2c, the leadership of a single wire rope 4₁₁ on the rope drum 6 is shown wound, which corresponds to the driving position of the recovery vehicle 1 according to Fig.2a. The four suspension cables 4₁₁ to 4₁₄ are each attached at one end via a cable clamp 4₅ and a cable lock 4₄ to a corner of the lower cross member 4₂ and at the other end comprise the cable drum shaft 6₃ with a cable loop 4₆.

For lowering or lifting the recovery vehicle 1, a cable pulling device , generally designated 5, is provided according to FIG . The pulling device 5 1 is attached to one side of the recovery basket 3, as can be seen from FIG. 3 a, and engages with its pulling rope 5 2 in the opposite direction to the four suspension cables 4 11 to 4 1 on the cable drum 6. The cable routing of a total of five traction ropes, these are the four suspension ropes 4₁₁ to 4₁₄ and the traction rope 5₂ of the cable pulling device 5, on the cable drum 6 can be seen from the detail identified in Fig.3b with IIIc from Fig.3c. Accordingly, five running grooves are formed in the rope ring 6 1 of the rope drum 6, of which the middle groove receives the pull rope 5 2 of the rope pulling device 5 and the remaining four Grooves for the four suspension cables 4₁₁ to 4₁₄ are intended. An upper 6₅ and a lower bearing plate 6₄ are arranged on the rope ring 6 1, with which both a total stroke limitation and a partial stroke limitation are provided for lowering or lifting the recovery vehicle 1 from the driving position F into the recovery position B or vice versa:
