Description

Cableway vehicle with rotary climbing device

The invention relates to a cableway vehicle for a cableway, and a method for climbing persons from a cableway vehicle of a cableway

Method of stepping on a unit of a cableway support to a cableway.

Cableways are available in various embodiments, mostly for transporting people and/or goods, for example as urban vehicles or for transporting people in ski resorts. Here, ground cable cars (standbuilding) are known, wherein the rail cars are mostly fixed to steel wire cables (wire ropes/cables) in order to be pulled by the steel wire cables. The movement takes place on the ground, wherein ground cable cars are mostly used on mountain sections. In contrast, in the case of aerial cableways, cableway vehicles (for example, gondolas, cars or chairs) are carried by one or more (steel) cables without fixed guides and are moved suspended in the air. Thus, the cableway vehicle does not come into contact with the ground. Aerial ropeways are commonly used for rough terrain, mostly on mountain road sections (e.g. in ski farms), in order to transport people from valleys to mountains. Usually, a cableway has two stations between which a cableway vehicle moves.

Here, a distinction is made between a circulating cableway and an aerial cableway (reciprocating cableway). In the case of aerial ropeways (reciprocating ropeways), one or two cableway vehicles pulled by traction cables travel back and forth on carrying cables on a travel path between two stations. In contrast, the revolving cableway has an endless, constantly revolving conveyor cable between the stations, on which a plurality of cableway vehicles (such as gondolas, cars or chairs) are suspended. The cableway vehicle thus moves from station to station on one side and back again on the other side. The movement of the cableway vehicle is therefore always substantially continuous in one direction, similar to a continuous conveyor.

In order to be able to span larger distances, one or more cableway supports for guiding (carrying/pulling) the cables are usually arranged between the two stations. A plurality of rollers are usually arranged on the runway support, for example in the form of so-called roller sets (rollenbatteries), in order to carry and guide the cables. In order to be able to carry out maintenance and repair on the cable support, in particular on the rollers, a step-on unit is usually provided on the cable support. Such a step-on unit may, for example, be implemented in the form of a (maintenance) platform and/or steps, which can be accessed (stepped on) by maintenance personnel. Furthermore, safety devices may be provided to increase the safety of maintenance personnel, such as railings.

The height of the cableway rack may vary from a few meters to over 150 meters depending on the purpose of use and the terrain. Up to now, the stepping unit of the cableway stand can only be stepped up from the ground by means of a ladder. However, this boarding is very laborious and time-consuming due to the often impassable terrain, in particular due to the sometimes high cableway supports.

Service pods are known in the art, for example from US 2012/0240812 A1. The nacelle has a platform arranged on a pylon, which platform can be accessed from the nacelle by means of a fixed ladder. However, it is impossible to climb

To the step-on unit of the cableway rack.

EP 2 810 842 A1 discloses a climbing aid with a ladder and a platform that can be fastened to a pylon, which can be mounted on a conventional cableway vehicle, such as a gondola or a chair. In this case, it is also not possible to climb onto the step-on unit of the cable support.

Evacuation ladders are known in the field of suspended sky railings, for example as disclosed in CN 207241689U. In this case, it is possible to leave the passenger compartment via a first evacuation ladder via a roof hatch (roof hatch) in order to reach the roof. The roof skylight is hingedly connected to the roof and may also serve as a second evacuation ladder. The roof hatch can rest on the evacuation platform to climb up the evacuation platform from below through the small window (hatch). The cars on which the railroads are suspended are relatively large, heavy, and typically run on parallel rails with wheels. Thus, the car is not or only very slightly vibrated during operation. However, on cableways, oscillations often occur when the cableway vehicle is moved by means of flexible carrying cables, which oscillations are also exacerbated by, for example, wind forces. The evacuation system of CN 207241689U is therefore not suitable for transferring from a cableway vehicle of a cableway onto the stepping unit of a cableway bracket of the cableway, since the evacuation ladder can easily become loose.

It is therefore an object of the invention to make it easier for people to board a step-on unit of a cableway rack of a cableway.

According to the invention, this object is achieved by: a climbing device is provided on the cableway vehicle for climbing persons from the cableway vehicle onto the step-on unit of the cableway support of the cableway, wherein the climbing device is displaceable relative to the cableway vehicle between a stowed position, in which the climbing device is stowed on the cableway vehicle, and a deployed position provided for climbing, wherein a fastening part is provided on the climbing device for releasably coupling the climbing device to the step-on unit of the cableway support in the deployed position. The step-on unit can thus be directly taken up from the cableway vehicle, which is much more labour-and time-saving for the maintenance personnel than by means of a ladder from the ground.

Preferably, a vehicle retaining device is provided at the cableway vehicle to releasably couple the climbing device in the stowed position with the cableway vehicle by means of the fixing portion. The climbing device can thus be fixed to the cableway vehicle during driving.

The cableway vehicle is preferably designed as a maintenance vehicle, wherein a step-on platform for the persons is provided in the upper region of the cableway vehicle, wherein the vehicle retaining device is arranged on the step-on platform. In this way, the climbing device can also be used in the stowed position to reach the stepping platform.

A locking unit can be provided at the fixed part of the climbing device, so that the climbing device is locked at the step-on unit in the deployed position and/or at the cableway vehicle, in particular at the vehicle retaining device, in the stowed position. The locking unit preferably has at least one locking element, wherein the locking element is preferably pretensioned by means of at least one pretensioning element. By providing a locking unit, the risk of the climbing device disengaging (detaching) in an undesired manner can be reduced, so that safety can be improved.

For better holding during the climbing process, the climbing device preferably has at least one stepping and/or holding (grasping) element for stepping and/or holding (grasping) of the person.

It may furthermore be advantageous if the length of the climbing device is variable, in order to adapt the length of the climbing device to the variable distance between the stepping unit and the cableway vehicle.

The climbing device can be designed in one piece or it can have a climbing unit to which at least one fastening element is fastened, wherein a fastening portion is provided at the fastening element. The climbing unit can advantageously be designed as a ladder, preferably a telescopic ladder. Due to the multi-part design, the parts can be replaced if necessary in case of damage, or a different length of the climbing unit can be used.

At least one sensor for generating a sensor signal relating to the state of the climbing device and at least one warning unit for generating a warning, preferably an acoustic warning, relating to the sensor signal obtained by the sensor can also be provided at the cableway vehicle. Thus, if the cableway vehicle moves while the climbing device is coupled to the step unit, an alarm can be generated, whereby the safety of operation can be improved.

Preferably, the climbing device is designed to allow relative movement between the climbing device and the cableway vehicle in the coupled state on the step-on unit in the deployed position. Thereby, any swinging of the cableway vehicle can be compensated.

The object is further solved by a cableway according to claim 12 and by a method according to claim 16.

The invention will be explained in more detail hereinafter with reference to fig. 1 to 3, which fig. 1 to 3 show by way of example, schematically and without limitation, advantageous design configurations of the invention. Shown in the drawings:

fig. 1 shows a cableway vehicle, which has a climbing device in a coupled state on a climbing unit of a cableway stand,

figure 2 shows a cableway vehicle with a climbing device in a stowed position,

fig. 3 shows a detailed view of the upper region of the creeper in the coupled state on the step-on device of the cableway support.

Fig. 1 shows a cableway support 1 of a cableway 2 designed as a cableway, which has a roller train 3 and a step-on unit 4. The construction of such a runway 2 is known in principle and therefore only the parts essential to the invention are described here. The roller group 3 has a plurality of rollers 5 following one another, on which the conveyor cables 6 of the cableway 2 are guided. The roller sets 3 are fixed to the runway support 1 in order to support the load of the conveyor cable 6 and in particular the runway vehicle 7 arranged thereon by means of the runway support 1 on the ground. A plurality of cableway vehicles 7 are usually suspended at a distance from each other on the carrying cables 6. For example, the securing of the cableway vehicle 7 to the conveyor cable 6 can be accomplished by a releasable clamping mechanism 8 as shown, so that the cableway vehicle 7 can be disconnected from the conveyor cable 6 in the station.

Such uncoupling may be performed, for example, in order to reduce the speed of passage through the station, so that the person can get on or off the vehicle more easily. However, the disconnection can also take place, for example, after the operation of the cableway vehicle has ended, in order to park the cableway vehicle outside the operating time, for example in a suitable garage. Of course, a non-releasable connection of the cableway vehicle 7 to the carrying cable 6 is also possible. In the example shown, the cableway vehicle 7 is designed as a service vehicle for servicing the cableway 2. Maintenance vehicles typically have an at least partially open cab so that the maintenance vehicle can be removed for maintenance. For example, the car (cabin) of a maintenance vehicle may have a metal frame with a closed floor and partially closed sides.

The step-on unit 4 of the cableway support 1 is designed here as a staircase with several steps 11 and can be used, for example, for maintenance work on the roller sets 3 or other parts of the cableway support 1. Depending on its design, the roller groups 3 are usually accessible (climbed) only from one side, i.e. from the inside facing the runway support 1, by the stepping unit 4. The opposite outer side of the roller group 3 cannot be reached by the step-on unit 4 or can be reached only with difficulty. In the embodiment shown, the service vehicle therefore also has an inspection platform 10, which is arranged in the upper region of the service vehicle. The inspection platform 10 can be accessed from the car by means of a ladder 9, which is usually fixed. From the car, personnel can thus climb up the inspection platform 10 via the ladder 9, for example to perform certain maintenance activities outside the roller set 3.

The tread unit 4 can be fixed to the roller set 3 and/or to the cableway bracket 1 itself. In the example shown, a railing 12 is also provided on the step 11 to improve the safety of the person when using the stepping unit 4. Of course, this is only an example, and the tread unit 4 can also be constructed in any other way and for example only have one platform with or without a railing 12. The step-on unit 4 can also be a part of the cableway support 1, for example, directly, if the cableway support 1 is embodied as a truss structure.

A maintenance ladder 13 is schematically indicated on the cableway support 1, by means of which a person, in particular a maintenance person, can climb from the ground onto the step-on unit 4. Of course, such a service ladder 13 may have additional safety elements, such as a housing (cage), to prevent personnel from falling down. Up to now, boarding of the step-on unit 4 has basically been only by such a maintenance ladder 13. It can be seen directly that boarding by means of the maintenance ladder 13 is very laborious and time-consuming, which is of course disadvantageous, especially in the case of very tall cableway racks 1. There is an additional difficulty: the runway supports 1 are often placed in inaccessible places, such as steep rocky terrain, which makes it very difficult to reach the runway supports 1 on the ground. In addition, there is a limitation in luggage such as tools when the maintenance ladder 13 is used.

In order to facilitate the climbing of persons onto the stepping unit 4, according to the invention a climbing device 14 is provided on the cableway vehicle 7 for climbing persons from the cableway vehicle 7 onto the stepping unit 4 of the cableway stand 1 of the cableway 2. The climbing device 14 is movable relative to the cableway vehicle 7 between a stowed position (fig. 2), in which the climbing device 14 is stowed on the cableway vehicle 7, and a deployed position (ready position) shown in fig. 1, which is provided for climbing. A fixing part 15 is provided on the climbing device 14 for releasably coupling the climbing device 14 to the stepping unit 4 of the runway support 1 in the deployed position. For this purpose, suitable support holding means 16 are preferably also provided on the step-on unit 4, which correspond in a suitable manner to the fixing unit 15. The fastening part 15 is preferably designed to achieve a form-fitting coupling with the step-on unit 4 that is as stable as possible, substantially at least one-sided. For this purpose, the fixing portion 15 may for example have at least one receiving opening 20 for receiving a portion(s) of the step-on unit 4, as will be explained in more detail below.

In an advantageous manner, the climbing device 14 is also designed such that in the deployed position, in the coupled state on the step-on unit 4, a certain relative movement between the climbing device 14 and the cableway vehicle 7 is possible. Thereby, it is ensured that the climbing device 14 remains coupled to the step-on unit 4 even when the cableway vehicle 7 swings, and does not detach from the step-on unit 4 due to the vibration of the cableway vehicle 7. Depending on its design, the cableway vehicle 7 often vibrates or oscillates during operation of the cableway 2. For example, lateral oscillations can occur as a result of the cableway vehicle 7 being suspended on the conveyor cable 6 and the conveyor cable 6 essentially acting as a pivot axis. The back and forth movement in the direction of movement may lead to, for example, braking processes and acceleration processes. In general, it may also be necessary to allow a certain degree of freedom of oscillation. To enable this, for example, one or more swivel joints, for example on a cable clamp, can be provided on the suspension device of the cableway vehicle 7, by means of which the cableway vehicle 7 is firmly or releasably fixed to the carrying cable 6. Due to the relatively small mass of the cableway vehicle 7, vibrations can be excited or amplified relatively easily, for example due to wind forces acting on the cableway vehicle 7 and/or due to the weight movement of the persons in the cableway vehicle 7.

For the purpose of climbing, the cableway vehicle 7 is moved to a climbing position close enough to the stepping unit 4 and stopped. Then, a person on the cableway vehicle 7 can manually move the climbing device 14 from the stowed position into the deployed position and releasably couple the fixed part 15 of the climbing device 14 to the step-on unit 4, in particular to the stand retaining device 16 arranged on the step-on unit. After coupling, a person can climb from the cable car 7 onto the step-on unit 4 by means of the climbing device 14, for example, for maintenance work on the roller set 3. Since the cableway vehicle 7 may be subjected to certain vibrations as already mentioned, for example due to the movement of persons in the cableway vehicle 7, it is advantageous if, in the coupled state at the step-on unit 4, a certain relative movement is possible between the crawlers 14 and the cableway vehicle 7. However, the maximum allowed relative movement should not be too great so that the climbing device 14 does not become completely detached from the cableway vehicle 7. For example, the degree of freedom of the relative movement may be limited by stops (not shown) and/or by ropes (cables) (not shown) connecting the ramp 14 and the cableway vehicle 7. When the work is completed, the person can be transferred from the passage unit 4 back to the cableway vehicle 7 by means of the transfer device 14. The transfer device 14 can then be released from the access unit 4 and moved back from the parking position into the storage position, and the cableway vehicle 7 can be moved again, for example onto the next cableway stand 1, in order to carry out maintenance work there again.

For increased safety, it can be advantageous if a locking unit 21 is provided on the fixing portion 15 of the climbing device 14 in order to lock the climbing device 14 in the deployed position at the step-on unit 4, in particular at the stand retaining device 16 provided thereon. Thereby, it can be ensured that the crawler 14 is not unintentionally disengaged (detached). Advantageously, the climbing device 14 also has at least one stepping and/or holding element 17 for stepping and/or holding (grasping) the person to facilitate climbing. Of course, it is preferred to provide a plurality of holding elements 17. It may also be advantageous if the length of the climbing device 14 is variable in order to adapt the length of the climbing device 14 to the variable distance between the stepping unit 4 and the cableway vehicle 7. The positioning of the cableway vehicle 7 in the climbing position in the region of the step-on unit 4 does not therefore need to be quite precise, but the length of the climbing device 14 can be simply adjusted and adapted to the respective distance. In the example shown, the climbing device 14 is embodied in several parts and has a climbing unit 14a, at the ends of which two fixing elements 15a are arranged, at which fixing parts 15 are provided. The climbing unit 14a may advantageously be designed as a ladder, as in the example shown. The climbing unit 14a may advantageously be designed as a ladder, as in the example shown. For example, a telescopic ladder may be provided as the climbing swivel unit 14a to adjust (adapt) the length.

In fig. 2, only the cableway vehicle 7 is shown, while for the sake of a better overview neither the carrying cable 6 nor the cableway support 1 (including the step-on unit 4) is shown. The climbing device 14 is here shown in a stowed position, in which the climbing device 14 is stowed on the cableway vehicle 7. For operation of the cableway 2, i.e. movement of the cableway vehicle 7, the crawlers 14 are preferably in the stowed position shown and are preferably fixed to the cableway vehicle 7 to prevent accidental uncoupling. For this purpose, vehicle retaining devices 18 can also be provided on the cableway vehicle 7 in order to releasably couple the traversing device 14 with the cableway vehicle 7 by means of the fastening portion 15 in the stowed position. If a locking unit 21 is provided on the climbing device 14, this locking unit 21 can also be used to lock the climbing device 14 in the stowed position on the cableway vehicle 7, in particular on a vehicle retaining device 18 provided at the cableway vehicle. Thereby it is ensured that the climbing device 14 does not get loose (released) unnecessarily during the movement of the cableway vehicle 7.

In an advantageous manner, a stepping platform 19 can be provided in the upper region of the cableway vehicle 7. In this case, the vehicle retaining device 18 is advantageously arranged on the step-on platform 19. In the example shown, the vehicle retaining device 18 has two retaining elements 18a which are fixed to the step-on platform 19 and project beyond the edge of the step-on platform 19. The two holding elements 18a are connected to a holding rod 18 b. The climbing device 14 can be hung (hooked) to the retaining bar 18b by the fixing portion 15 in the shown stowed position in order to releasably couple the climbing device 14 with the vehicle retaining device 18.

In the stowed position, the climbing device 14 can also be used to reach the landing 19, for example from the car of the cableway vehicle 7. In the case shown, for example, a first person can be climbing onto the inspection platform 10 via the ladder 9, while a second person can be climbing onto the stepping platform 19 via the climbing device 14. For example, a second person stepping on platform 19 may support a first person on platform 10 while inspecting roller set 3. A corresponding distance is of course provided between the landing platform 19 and the retaining bar 18b, which distance is dimensioned sufficiently large to allow a person to be able to climb from the car onto the landing platform 19 by means of the climbing device 14.

The climbing device 14 can thus also be used independently of the climbing unit 4 climbing onto the cableway support 1. For example, the cableway vehicle 7 can first be moved into a climbing position in the region of the climbing unit 4 of the cableway stand 1, while a first person can climb onto the climbing unit 4 via the climbing device 14. The second person may then (while the first person is already on the crawler 4) move the crawler 14 back to the stowed position. The cableway vehicle 7 can then be moved further into a position in which the inspection platform 10 of the cableway vehicle 7 is opposite the step-on unit 4 of the cableway stand 1 transversely to the direction of movement. Thereby, the second person can perform maintenance work at the outer side of the roller set 3, and the first person can perform maintenance work at the inner side of the roller set 3.

Fig. 3 shows a detailed view of the upper region of the climbing device 14 in the coupled state on the step-on unit 4 in the deployed position. For a better overview, the remaining components (carrying cable 6, cableway vehicle 7, cableway support 1) are not shown. In the example shown, a stand holding device 16 is provided on the step-on unit 4. Here, the stand holding means 16 has two fixed arc stands 16a fixed at the side on the lowest step 11 of the stepping unit 4. Of course, the fixed arc bracket 16a may be integrally designed with the step-on unit 4. However, in order to be able to easily retrofit the stand holding device 16 onto an existing step unit 4, it is advantageous if it is designed as a separate component. The fixed arc bracket 16a is connected with a link 16b on which the fixed portion 15 of the climbing device 14 is arranged in order to releasably couple the climbing device 14 to the step device 4.

As already mentioned, the climbing device 14 has here a (one) climbing unit 14a embodied as a ladder and two separate fastening elements 15a, which are fastened laterally at the upper end of the ladder. Thus, the fixed portion 15 of the climbing device 14 is formed on two fixed elements 15 a. Thus, for example, a conventional, commercially available ladder, preferably made of a lightweight, weather-resistant material of sufficient strength, such as aluminum, may be used as the climbing device 14 a. Of course, the climbing device 14 may also be integrated with the integral stationary portion 15. However, the advantage of using a ladder and at least one separate fixing element 15a on which the fixing portion 15 is formed is that the ladder can be easily replaced, for example in the event of damage, and/or that ladders of different lengths can be used.

In the embodiment shown, both fixing elements 15a have a receiving opening 20 which opens downwards, through which receiving opening 20 the climbing device 14 can be hung in the deployed position on the link 16b of the stand holder 16 (and likewise on the vehicle holder 18 in the stowed position). The receiving opening 20 is preferably dimensioned such that the connecting rod 16b is enclosed by the fastening element 15a in a substantially U-shaped manner. In order to additionally protect the climbing device 14 against unintentional disengagement from the step device 4, it is advantageous, as mentioned above, if a locking unit 21 is provided on the stationary portion 15. In the example shown, each fixing element 15a is provided with a (one) locking element 21a, which is connected to the respective fixing element 15a in an articulated manner on one side at a rotation point P.

In this way, when the link 16b is inserted into the receiving opening 20, the locking element 21a can be swung upward by the link 16 b. After the connecting rod 16b has been fully inserted into the receiving opening 20, the locking element 21a automatically swings downward again as a result of the force of gravity. Then, the respective free ends of the locking elements 21a rest on the inner surface of the receiving opening 20 opposite the rotation point P and close the open side of the receiving opening 20 from the inside, like a snap ring. Thus, the crawlers 14 are no longer unintentionally released from the links 16 b. Safety can be further increased if the locking elements 21a are pretensioned in the direction of the inner surface of the receiving opening 20 opposite the rotation point P by suitable pretensioning elements (not shown), for example mechanical springs, respectively.

To unlock the locking unit 21, the locking element 21a can be pivoted (pivoted) upwards against the force of gravity (against the pretensioning force of the pretensioning element, if necessary) far enough that, when the climbing device 14 is lifted, the connecting rod 16b can be moved out of the receiving opening 20 through the open side of the receiving opening 20. The operation of the locking element 21a can be performed manually, for example by a person from the stepping platform 19. However, a suitable (not shown) operating device (actuating device) can also be provided to pivot the locking element 21a out of the car of the cableway vehicle 7, for example, for unlocking the locking unit 21. For example, a suitable cable winch (cable drive) can be used as operating device (actuating device), which can also be arranged in the forming tube (profile tube) of the ladder. In principle, it is also sufficient if the locking element 21a is provided on only one of the fixing elements 15 a. Of course, the illustrated embodiment of the crawler 14 is understood to be exemplary only, and other suitable construction designs may be provided by the skilled artisan.

Preferably, at least one (not shown) sensor is also provided on the cableway vehicle 7 and/or the cableway support 1 for generating a sensor signal relating to the state of the climbing device 14, and at least one (not shown) warning unit is provided on the cableway support 1 and/or the cableway vehicle 7 for generating a warning, preferably an acoustic warning, relating to the sensor signal obtained from the sensor. For example, this allows an alarm to be triggered when the climbing device 14 is in the coupled state on the step-on unit 4 (in the coupled state with the step-on unit 4) in the deployed position and moves the cableway vehicle 6. For example, the sensors may be designed to detect relative movement or relative distance between the crawler 14 and the cableway vehicle 7 as the state of the crawler 14. When a relative movement occurs or a certain relative distance between the climbing device 14 and the cableway vehicle 7 is reached or exceeded, the sensor can generate a sensor signal, according to which the alarm unit triggers an alarm. Of course, the generation of the sensor signal also refers to the interruption of the signal.

In a simple embodiment, for example, a known touch switch can be provided as a sensor, the sensor signal being generated when a touch (contact) of the touch switch is interrupted. For example, when a certain relative distance is exceeded between the crawler 14 and the (one) part of the cableway vehicle 7, an interruption of the contact may occur, thereby causing the alarm device to trigger an alarm. When the alarm is triggered, the operator of the cableway 2 can react, for example stop the movement of the cableway vehicle 7. It is conceivable, for example, for a first contact element of a contact switch to be provided on the crawler 14 and for a second contact element of the contact switch to be provided on a component of the cableway vehicle 7, for example on the vehicle retaining device 18, which contact elements are in electrical contact during normal operation.

As long as the relative distance between the climbing device 14 and the cableway vehicle 7 is less than a certain triggering distance, contact between the contact elements is maintained. If the triggering distance is reached or exceeded, the contact between the contact elements is interrupted. Thus, the interruption of the electrical contact (contact) corresponds to the generation of the sensor signal. Thus, the alarm unit triggers an alarm when the contact (contact) is interrupted. To further improve the safety, the runway 2 may also have a control unit for controlling the drive of the runway 2, which control unit is arranged to control the drive of the runway in dependence of sensor signals obtained from the sensors. This makes it possible, for example, to automatically stop the drive of the runway 2 when the sensor signal is obtained, without the operator of the runway 2 having to stop the runway 2 in response to an alarm signal.

Finally, it should again be noted that the described embodiments are to be construed as merely illustrative and not restrictive. In addition to the embodiments shown, further variants are of course conceivable, which are determined by the person skilled in the art. For example, the skilled person can adapt the invention to the specific conditions of the cableway, such as different shapes of the cableway bracket 1, the tread unit 4, etc.
