Definitions

  • a cable car of the kind mentioned has infrastructures, in particular large and costly end stations, allowing, among other things, storage and sheltering of the cabins or skips during the night or at the end of the period of use.
  • the present invention starts from the observation that the power station, generally the downstream station of the cable car, comprises the noble parts of the installation, such as the motor for driving the towing cable, the control device and the tensioning devices for the carrying cables.
  • the upstream station only has the anchors for the carrying cables and the pulley for returning the towing cable, which can be exposed to the weather without risk of blockage or damage by frost or ice.
  • the object of the invention is to provide a cable car of which only one of the stations includes a shelter building.
  • Another object of the invention is to provide a cable car allowing storage of the two cabins in the same station, generally in the downstream station.
  • the conveyor according to the present invention is characterized in that one of said stations has at the end of the line a storage location for each of said cabins and that at least one of said coupling clamps is arranged to allow uncoupling of the tractor cable trolley at the end of the operating period when the associated cabin is in the storage location and an individual movement from the other cabin to the storage location.
  • the cabin located in the storage location is uncoupled from the tractor cable and the installation is restarted to bring the other cabin, always coupled to the tractor cable, from the upstream station to the downstream station in the storage location.
  • the upstream cabin being empty, the power of the tractor cable driving device is largely sufficient, despite the absence of the counterweight normally formed by the other cabin.
  • Each cabin is advantageously fitted with a clamp capable of being uncoupled from the tractor cable in order to facilitate the operation and the periodic movement of the clamps on the tractor cable.
  • the coupling clamp is according to a development of the invention, in the form of a policeman's cap, the sectors or end shoes of which are movable and controlled by a selective displacement jack in an active cable clamping position and in a inactive uncoupling position.
  • the jack advantageously controls knee pads whose active position corresponds to a stable position for extending the overshoot of the neutral position. Any other control system can of course be used.
  • the clamping action of the clamp is increased by the presence of a movable jaw cooperating with the central sector of the clamp in the form of a policeman's hat to form a clamping jaw.
  • the clamping force of the jaw is preferably derived from the bearing force of the tractor cable on the end sectors of the clamp by pivotally mounting the end sectors shaped as a multiplier lever.
  • a two-cable installation in this case a cable car, comprises two carrying cables 10, 12 extending between two end stations 14, 16 where they are anchored.
  • a towing cable 18 in closed loop passes in the drive station 14 on a drive pulley 20 and in the other station 16 on a return pulley 22.
  • the drive station 14 is advantageously located downstream and comprises a building 24, housing the drive motor (not shown) of the driving pulley 20 and all the controls of the cable car and extending by a shelter or storage location 25.
  • the tensioning devices (not shown) of the carrying cables 10, 12 are preferably also located in the station 14. On each carrying cable 10, 12 rolls a carriage 30 for supporting a bucket or cabin 26, 28 moving back and forth.
  • the carriages are coupled to the tractor cable 18 to move symmetrically, one of the cabins going up when the other goes down and vice versa.
  • stations 14, 16 passenger embarkation and disembarkation platforms are provided, one of the cabins being at the downstream station when the other is at the upstream station and vice versa.
  • Such cable cars are well known to specialists and there is no need to describe them in more detail.
  • the carriage 30 comprises a train of rollers 32 and an arm 34 to which the hanger 38 of the cabin 26, 28 is articulated by a pivot 36.
  • a clamp designated by the general reference 40, is carried by the end of the hanger 38 and encloses the tractor cable 18 to couple the carriage 30 to the tractor cable 18.
  • the clamp 40 in the form of an inverted policeman's hat, has a sector or central shoe 42 framed of two sectors or end shoes 44, 46 (fig. 2 and 3).
  • the central sector 42 is articulated on the pivot 36 'while the end sectors 44, 46 are slidably mounted on the upper part of the hanger 38 in order to be able to occupy two stable positions, a lowered position, separated from the central sector 42 and a raised position for approaching the central sector 42. In this last position for coupling to the tractor cable 18, the latter is sandwiched between the sectors 42, 44, 46 and extends along a sinuous trajectory in the form of a policeman's hat. In the separated position of the sectors 42, 44, .46, the carriage 30 is uncoupled from the tractor cable 18.
  • the end section 44 is articulated to the end 48 of a toggle with two links 50, 52, whose opposite end is pivotally mounted on a fixed pin 54 carried by the s "spente 38.
  • the connecting rod 52 is extended beyond the axis 54 by an arm 56 driven by the rod 58 of a hydraulic cylinder piston 60.
  • the p sect core 44 carries a pin 62 engaged in a vertical fixed light 64, provided on the hanger 38.
  • THE opposite end sector 46 is mounted symmetrically on a toggle 50 ', 52', articulated on a fixed axis 54 ', the extension 56' of the link 52 'being attacked by a rod 58' secured to the cylinder of the jack 60.
  • the journal 62 'of the sector 46 slides in a fixed light 64'.
  • the substantially aligned rods 50, 52 hold the end sector 44, 46 in the raised coupling position. This position can be a stable position if the knee lifter is in a position beyond the neutral position in abutment.
  • the sector 44, 46 is lowered, releasing the towing cable 18.
  • the hydraulic, electric or mechanical jack 60 actuates the two knee joints 50 simultaneously. 52; 50 ', 52'.
  • Each end sector 44, 46 is arranged in a lever articulated at an intermediate point 48, 48 ', the external arm - of the lever being shaped into a support surface 63, 65 of the towing cable 18, the internal arm forming a cam 66, 68 cooperating with an elongated jaw 70 disposed opposite the central sector 42 and forming with the latter a clamping jaw for the tractor cable 18.
  • the bearing force of the tractor cable 18 on the face 63 of the sector 44 tends to rotate. the latter in a clockwise direction and to apply the jaw 70 against the central sector 42.
  • the end sector 46 symmetrically presses the other end of the jaw 70 against the central sector 42.
  • the jaw 70 allows an increase in the grip of the clamp 40 on the tractor cable 18, sufficient for the proper functioning of the installation.
  • the cabin 28, which is located at the downstream station 14 in the storage location 25, is uncoupled from the tractor cable 18 by actuating the jack 60, for example by a hydraulic control on board the cabin 28 or connected temporarily to the jack 60.
  • the retraction of the jack 60 causes the knee pads 50, 52 to break; 50 ′, 52 ′ and the spacing of the end sectors 44, 46 and of the jaw 70 of the central sector 42, releasing the towing cable 18.
  • the engine is restarted to move the cabin 26 to the downstream station 14, the tractor cable 18 running freely in the open clamp 40 of the cabin 28 which remains stationary, The cabin 26 is thus brought into the storage location 25 belonging to the building 24.
  • a restart requires the prior displacement of the cabin 26 towards the upstream station 16 and the re-coupling of the cabin 28 to the tractor cable 18 by supplying the jack 60 bringing the sectors 42, 44, 46 and the jaw 70 in the clamping position.
  • any of the cabins 26, 28 located in the downstream station during the last trip is uncoupled from the tractor cable 18.
  • the change of the coupling point to the tractor cable 18 can be easily carried out by opening the clamps 40 in the manner described above. It is clear that the coupling clamp 40 is not designed for permanent operation and disengagement at each passage of the cabin 26, 28 in stations 14, 16 like the cable cars, but that the uncoupling operation is sufficiently simple and fast for actuation at the end of the day.
  • the clamp 40 in the shape of a policeman's cap with an additional clamping jaw 70 allows reliable coupling, but it is understood that any other clamp, for example hydraulically controlled, can be used to couple the carriages to the towing cable.
  • the drive station can be located upstream and the storage location can be separated from the drive station according to the topography of the location.
  • the invention is of course in no way limited to the embodiment of the invention more particularly described; and it extends to a clamp of the type described above for a conventional cable car or shuttle.
