Definitions

  • the invention relates to a rescue device according to the preamble of claim 1.
  • Document DE-C-889. 166 essentially relates to a rescue device for a two-cable installation in which the rescue nacelle rolls on the carrying cable as well as the trolley of the vehicle towed by the nacelle.
  • An alternative embodiment, suitable for a single-cable installation and illustrated in FIG. 3, makes use of two trolleys, in this case an auxiliary trolley, specially brought in and a rescue trolley.
  • the vehicle clamp is attached to the auxiliary cart and the auxiliary cart is towed by the rescue cart.
  • the stability of the assembly implies a lifting of the cable clamp and the auxiliary carriage must carry the vehicle.
  • the use of two independent carts complicates the device and contributes to its insecurity.
  • the present invention aims to facilitate rescue operations while improving safety conditions.
  • the cabin Passengers remain in the vehicle or in the seat, hereinafter called the cabin, until arrival at the station or pylon where they can easily get off.
  • This rescue mode is particularly suitable for large capacity cabins of the type used in gondolas with two parallel tractor-carrying cables, the passengers being evacuated together and not by individual descent to the ground in locations often difficult to access. It is important to correctly guide the rescue cart in its movement on the cable to avoid any crossing and derailment, especially during the cab towing phase.
  • the clamp (s) are open to allow sliding on the immobilized cable.
  • the opening can be controlled by actuation of the disengaging mechanism or by any other means.
  • the connection between the rescue cart and the clamp transmits the guiding forces to the clamp and the assembly is preferably arranged to maintain the clamp and the cable coaxially during the sliding of the clamp on the cable.
  • the rescue trolley may include, in addition to the rollers, guide rollers, possibly retractable to facilitate passage over the clamps as well as anti-derailment devices trapping the cable.
  • the guidance is facilitated by fixing the cabin in the axis under the rescue cart, but a simple hooking at the rear of the cart is conceivable if care is taken to provide suitable guidance means.
  • the rescue cart advantageously carries a nacelle for the rescuer who must ensure the coupling and opening operations of the clamps.
  • the rescue device can be used for gondola lifts with one or more carrier cables with disengageable or fixed clamps as well as for simplified installations such as chairlifts with fixed or disengageable attachments, the only condition being the possibility of open the fasteners to slide them along the immobilized cable.
  • the towing cable can be installed permanently, in particular in a closed loop along a section of the line delimited by pylons and / or a station and this cable passes over a driving pulley whose drive is independent of the main engine.
  • the rescue trolley preferably stored at the end of the section, can thus be brought quickly to the right of the immobilized cabin, which can be towed upstream and downstream.
  • a simplified device may include a simple winch arranged or installed upstream of the section, which does not must then have no slope inversion. The cabin can be towed upwards or if the slope is sufficient it can slide by gravity while being retained by the towing cable.
  • two carrier-tractor cables 10, 12 of a gondola extend parallel in closed loop between two stations, only one of which is visible, passing over support or compression pylons 16 .
  • the two cables 10, 12 are driven in synchronism and cabins or vehicles, of which only one cabin 18 is shown, are coupled in line to the two cables 10, 12 by clamps 20.
  • the invention is described below in its application to a detachable gondola, which is the subject of European patent N ° 93.680 to which reference will advantageously be made for further details, but it is applicable to an installation of the pulsed type, to a single or multi-cable installation or to detachable or non-detachable chairlifts.
  • Each cabin 18 is suspended by a hanger 22 from a cabin carriage 24 carrying four clamps 20.
  • the cabins 18 are uncoupled from the cables 10, 12 by opening the clamps 20 and braking to allow boarding and disembarking of passengers at a standstill or at slow speed from the cabins, which circulate on transfer rails before being re-accelerated and re-coupled to the cables 10, 12 at the exit from station 14.
  • Such installations are well known and it it is unnecessary to describe them in more detail.
  • the rescue device comprises a rescue cart 26 with two pairs of rollers 28, 30; 32, 34 running on the two cables 10, 12.
  • the rescue trolley 26 is placed on the two cables 10, 12 for a rescue operation in the event of immobilization of the cables 10, 12, for example during a failure of the drive system.
  • the rescue cart 26 is stored on the pylon 16 and a gantry, not shown, or any other suitable means allows its removal or its establishment on cables 10, 12. It is clear that the rescue cart 26 can be stored in another place and be brought on site if necessary.
  • the rescue trolley 26 can also be in the station 14 on a delivery track allowing its transfer to the cables 10, 12.
  • a towing cable 36 extends in a closed loop along the section delimited by the station 14 and the pylon 16 passing over deflection and support pulleys 38, 40 one of which 40 is driving.
  • the cable 36 extends in the axis of the upward and downward path of the gondola and its ends are moored at the front 42 and at the rear 44 of the rescue cart 26.
  • a rotation of the driving pulley 40 drives the towing cable 36, which moves the rescue carriage 26 along the cables 10, 12 up or down.
  • the rescue trolley 26 and more particularly its rollers 28-30 are arranged to pass over the cabin trolley 24 and to come into an overlapping position, shown in FIGS. 5 to 7, in which the rollers 28-34 frame the cabin trolley 24.
  • Connection tabs 46, 48 respectively secured to the rescue trolley 26 and the cabin trolley 24 and shown in detail in FIG. 16, allow a rigid connection by pins or bolts 50 between the two carts 24, 26 overlapping.
  • the lateral guidance of the rescue trolley 26 on the cables 10, 12 is improved or ensured by four pairs of guide rollers 52, 54 with vertical axes arranged in line with the rollers 28-34, each pair of guide rollers 52, 54 tightly framing the associated cable 10, 12 (see fig. 15).
  • the guide rollers 52, 54 are either retractable to allow the passage of the rescue trolley 26 on the clamps 20, or put in place during the coupling of the two trolleys 24, 26.
  • Each rolling roller 28-34 is associated a safety yoke 56 which frames the cable 10, 12 corresponding in the manner shown in FIG.
  • a safety pin 58 closes the yoke 56 by trapping the cable 12. These pins 58 are removed to separate the rescue trolley 26 from the cables 10, 12 after the rescue operation, as well as for the passage of the rollers 28-34 on the clamps 20, the yokes 56 being pivotable or retractable.
  • the rescue cart 26 carries a basket 60 transport of a rescuer 62.
  • the rescue device operates as follows: When one or more cabs 18 are immobilized on the section equipped with the rescue device, the rescue cart 26, moored to the towing cable 36, is placed on the cables 10, 12, for example at the height of the pylon 16.
  • the rescuer 62 takes place in the nacelle 60 and by starting the drive motor of the driving pulley 40 the rescue trolley 26 is lowered slowly towards the immobilized cabin 18.
  • the rescuer 62 removes the safety pins 58 and retracts the yokes 56, as well as the guide rollers 52, 54 arranged on the side of the rescue cart 26 passing over the cabin cart 24.
  • the rescue cart 26 is stopped in the position overlap illustrated in Figures 5-7, and the rescuer couples by means of the bolts 50 the carriages 24, 26. It replaces the safety pins 58 and the guide rollers 52, 54 and opens the clamps 20, by example per action gripping and locking of the gripper control lever 63 (fig. 16).
  • the towing cable 36 By restarting the towing cable 36, the cabin 18 is brought either to the pylon 16 or to the station 14, the open clamps 20 sliding on the cables 10, 12. Any crossing of the cabin carriage 24 is prevented by the rigid connection with the rescue cart 26, itself perfectly guided by the rollers 28-34 and guide 52, 54.
  • the cables 10, 12 are centered in the open clamps 20 avoiding any lateral friction against the jaws .
  • each line section is equipped with a rescue device, which does not interfere with the normal operation of the installation if the care is taken to separate the rescue trolley 26 from the cables 10, 12 to allow the free passage of the cabins 18 and their cabin trolley 24.
  • a towing cable 36 in a loop allows rescue on sections having both slopes ascending and descending slopes, the rescue trolley 26 being retained either by one or the other of the strands of the towing cable 36.
  • FIG. 2 shows a rescue device having a simple winch 64 with a drum, mounted on the pylon 16 and the cable of which, hooked to the rescue cart 26, constitutes the towing cable 36. It is clear that this simplified device is not not usable on a section with slope reversals and the cabin 18 is necessarily towed towards the pylon 16.
  • the rescue trolley 26 and its operation are of course identical to those described above and it is unnecessary to recall them.
  • Figures 9 and 10 show a rescue device for a single cable gondola or chairlift with detachable clamps.
  • the cabin carriage is constituted by a beam 66 carrying at each of its ends a disengageable clamp 20, the two clamps 20 enclosing the same cable 10 at spaced locations.
  • the rescue trolley is constituted by a spar 68 carrying two rollers 28, 32 for rolling on the cable 10.
  • the other parts of the rescue trolley are identical to those described above, in this case the legs fixing 46, the guide rollers 52, 54 and the safety yokes 56, the single-cable rescue cart 68 being exactly one half of the above-mentioned rescue cart 26.
  • a counterweight 70 balances the weight of the basket 60.
  • the cabin trolley 66 can obviously comprise a single clamp or a greater number.
  • FIG. 11 to 13 we see a device for rescue according to the invention for a single cable installation with a single non-detachable clamp 72.
  • the rescue cart 74 is identical to the rescue cart 68 described above, but the connecting lugs 46 are replaced by two stirrups 76, 78 which can be opened in the closed position enclose the body of the clamp 72.
  • Such a system can be used on a simple chairlift, the fixed clamps of which can be easily opened and kept open during the sliding phase on the immobilized cable.
  • the rescue device can be modified without departing from the scope of the invention, for example by transferring certain guide elements which can be put in place for the rescue operation to the cabin carriage 24, 66, 72 or reducing at least partially the load carried by the open clamps by transferring it to the rescue cart.
  • the maneuver can be simplified by simply hooking the cabin trolley to the rear of the rescue trolley, but special precautions for lateral guidance are required.
  • the rescue trolley can for example carry a pivoting arm which in the active position straddles the cabin trolley and carries at its end guide rollers cooperating with the cable. This reconstitutes a frame of the cabin trolley by the rescue trolley, but without passing from one to the other.
  • the rescue trolley 26, 68, 74 be perfectly guided to avoid any crossing and that this guidance is transmitted to the cabin trolley 24, 64, 72, which thus remains aligned with the cables 10, 12 during sliding thereon. This prevents any jamming or risk of derailment of the cabin trolley.
  • the rescue trolley must also ensure the centering of the cables 10, 12 between the jaws of the clamps 20 open, to prevent friction of the cables against these streaks during the shifting, friction which can generate an asymmetry and favor a crossing.
  • Figures 17 and 18 illustrate a rigid connection mode between the carriages 24, 26 without requiring a superposition of these.
  • On the rescue trolley 26 are articulated two parallel arms 80, 82 whose spacing corresponds to the width of the cabin trolley 24.
  • the articulation axis of the arms 80, 82 is arranged at the rear, on the side of the trolley cabin 24 and these arms 80, 82 can occupy either an inactive position folded down on the rescue trolley 26, or an active position of coupling to the cabin carriage 24.
  • the arms 80, 82 extend at the rear, in the extension of the rescue trolley 26 and surround the cabin trolley 24, to which they are coupled, as described above, by connecting lugs 46, 48, to form a rigid assembly.
  • the arms 80, 82 advantageously carry guide rollers 52, 54 framing the cables 10, 12 and improving the guidance.
