Definitions

  • the present invention concerns a safety device for the forced execution and the control of the gripping at the exit from a station for a continuous motion single cable cableway with temporary disconnection of the cars.
  • rails for the guiding of the car are usually located at the exit from stations which in the case of detachment of the car from the carrying cable receive and guide the car during its fall, thus preventing major damages.
  • object of the present invention has been to provide a safety device that is capable to operate already in the gripping stage by forcing the clamping of the car onto the carrying cable and ensuring that the gripping is done in a correct way before the same leaves the station, that is a device operating in a preventive way instead of as a remedy for an already occurred accident.
  • such object is attained by means of a device characterised in that it comprises a plurality of mechanical guides inserted in the path that is run by the gripping vice of the car inside the station in order to force the same vice to close again on the transport cable before the exit of the car from the station.
  • electric controls are provided, that are purposed to verify the correct clamping condition of the vice to the cable before the car exits the station and, if this is the case, to signal the anomaly and to obtain the stop of the facility.
  • Figures 1 and 2 show the exit zone from a station for single cable cableway that provides for the temporary detachment of the car from the transport cable 1 at the entrance of the station and its subsequent reattachment before the exit from the station.
  • Such support device or better one of its possible embodiments, is represented in Figures 3-8, where this can be seen as being composed of a main body 4 which centrally bears a idle wheel 19 slidingly laying on a rail 5 supported by a fix longitudinal member 6 and that has an additional idle wheel 20 at its back end that is engaged into a C-shape guide 7.
  • the fore end of the main body 4 has instead a vice 8 with two turning jaws 9 that are capable to open up and close on the cable 1.
  • the support device is pulled along the station by a sequence of motorised rubber wheels 10 at a progressively increasing velocity toward the exit from the station (see also Figures 1 and 2).
  • a fix guide 12 with variable height is capable to engage itself with a idle wheel 18 located on top of a pair of springs 13 reacting between the body 4 of the support device and one end of an arm 14 fixedly mounted to one of the two jaws 9 of the vice 8 and to the fulcrum 15 in the articulation point between the two jaws.
  • the support device 2 is of the type known per se and therefore it will not be described in greater details.
  • the cable 1 is in turn guided by grooved motorised guiding drums 16 and by a fix guide 17 in order to follow, in the exit zone from the station, a path that is initially inclined from the bottom to the top and then horizontal up to the end of the station ( Figure 1).
  • a safety device that comprises a sequence of guides and electric sensors serving the purpose to co-operate with the vice 8 so as to verify its correct vertical and horizontal position and therefore the effective clamping on the cable.
  • first guide 22 with horizontal course and L-shape section that has its vertical arm inserted in the jaws of the vice 8 ( Figure 4) so as to ensure the maintening of the vice itself in a geometrically correct position.
  • a second horizontal extension guide 23 with L-shape section rotated by 90° ensures that the vice 8 does not lift nor slowly moves sideways toward the outside as regards to the correct vertical and horizontal position.
  • variable height guide 12 which provides to force the opening of the vice 8 against the opposite force of the springs 13
  • the guide 22 is substituted by a third horizontal guide 24 with a larger section vertical arm (Figure 5), that ensures that the vice 8 has reached a degree of opening such as to allow the entrance of the cable between the two jaws 9.
  • an electric sensor 25 detects the presence of the cable 1 in a suitable position for its entrance in the vice 8 ( Figure 6) and therefore the cable 1 effectively enters between the two jaws 9 and it is kept between the same two by a fourth horizontal guide 26 with L-shape section, which at the end of the guide 24 completes and is attached to the guide 23 so as to form a single C-shape guide 27 capable to maintain the vice 8 in the correct horizontal and vertical position and the cable 1 inside the vice itself ( Figure 7).
  • variable height guide 12 allows the springs 13 to force the closing of the vice 8 for the tight clamping of the same cable 1 and a pair of contoured electric sensors 28 envelops the vice 8 right after and the cable 1 enclosed in the same ( Figure 8) in order to detect and definitely communicate to a suitable control apparatus that the car is correctly attached to the cable 1 and can leave the station without danger of detachment and fall.
