Description

RESCUE TROLLEY, ESPECIALLY FOR A CABLE CAR OR TELE-

SEAT.

  The invention relates to a rescue device for a cable car having at least one carrying cable-tractor to which loads are coupled, in particular cabins by clamps capable of being opened in line for an operation.

  rescue in case of accidental immobilization of the cable.

  The significant transport capacities, as well as the length and the layout of the lines of modern installations make the rescue operations, in case of immobilization of the cable, of

more and more difficult and long.

  The object of the present invention is to facilitate operations by making it possible to bring back the cabins or seats immobilized in

  line to a station or pylon where the evacuation of passengers

gers is simple.

  The rescue device according to the invention is characterized in that it comprises a rescue cart having rollers on the immobilized cable, a towing cable attached to the rescue cart to bring the latter by rolling to the right of the cabin immobilized and means of taking charge of the cabin by said rescue trolley

  to haul the cabin along the immobilized cable after opening

  clamp size to separate the cabin from the carrying cable -

  tractor. 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 barter cables

  parallel torers, the passengers being evacuated together and not by individual descent on the ground in places 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

  during the towing phase of the cabin. After coupling the clamp or the clamp holder carriage from the cabin to the rescue cart the clamp (s) are open to allow

  slipping on the immobilized cable. In the case of pliers

  the opening can be controlled by actuating the declutching 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

  clamps as well as anti-derailleur devices

trapping the cable.

  Guiding is facilitated by fixing the cab in the axis

  under the rescue cart, but a simple hook on the rear

  The carriage is conceivable if care is taken to provide suitable guide means. The rescue cart advantageously carries a basket for the rescuer who must ensure

  the coupling and opening operations of the clamps.

  The rescue device according to the invention can be used

  for gondolas with one or more carrier-barter cables-

  detachable or fixed grippers as well as for installations

  Simplified options such as chairlifts with fixed or detachable fasteners, the only condition being the possibility of opening the fasteners to slide them along the immobilized cable. The towing cable can be permanently installed, 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 pulley

  power train whose drive is independent of the main engine.

  The rescue cart, preferably stored at the end of the dry-

  tion, can thus be brought quickly to the right of the immobilized cabin, which can be towed upstream or downstream. A simplified device may include a simple winch arranged or installed upstream of the section, which must then have no slope inversion. The cabin can be towed upwards or if the slope is sufficient it

  can slip by gravity while being retained by the cable

  masking. Other advantages and features will emerge more

  clearly from the description which follows of a mode of setting

  of the invention, given by way of non-limiting example

  In FIGS. 1 to 8, two carrier-tractor cables 10, 12

  of a gondola extend parallel in closed loop in-

  be two stations, only one of which 14 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 ac-

  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 which will advantageously be referred to for more details, but it is applicable to an installation of the pulsed type, to an installation single cable: or multi cables or

  detachable or non-detachable chairlifts.

  Each cabin 18 is suspended by a hanger 22 from a cabin carriage 24 carrying four clamps 20. At the entrance to the station

  14 the cabins 18 are uncoupled from the cables 10, 12 by or-

  Greening of 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 of the station 14. Such facilities are well

  known and need not be described in more detail.

  The rescue device according to the invention comprises a carriage

  rescue 26 with two pairs of rollers 28, 30; 32, 34 rolls

  ment 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 drive system failure. In the installation

  tion shown in Figure 1, the rescue cart 26 is stored on the pylon 16 and a gantry, not shown, or any other suitable means allows its removal or placement on the cables 10, 12. It is clear that the rescue cart 26 can be stored in another place and brought on

  place if needed. The rescue cart 26 can also

  ment be in station 14 on a delivery track allowing its transfer to cables 10, 12. A towing cable 36 extends in a closed loop along the section delimited by station 14 and pylon 16 passing over deflection pulleys

  and support 38, 40, one of which 40 is driving. Cable 36 goes

  tends 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

  drive pulley 40 drives tow cable 36, which

  places the rescue cart 26 along the cables 10, 12 in

  up or down. Rescue cart 26 and over

  in particular, its rollers 28-30 are arranged to pass over the cabin carriage 24 and to come into an overlapping position, shown in FIGS. 5 to 7, in which the rollers 2834 frame the cabin carriage 24. Connection tabs 46, 48, respectively integral with the rescue trolley 26 and the cabin trolley 24 and shown in

  detail in figure 16, allow a rigid connection by gou-

  pins or bolts 50 between the two carriages 24, 26 overlap each other

  singing. The lateral guidance of the rescue cart 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

  bearing 28-34, each pair of guide roller 52, 54 enca-

  tightly routing 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 yoke 2834 is associated with a yoke security 56

  which frames the corresponding cable 10, 12 in the manner shown

  shown in Figure 14. 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 operation

  rescue ration, as well as for the passage of rollers

  Lement 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 according to the invention operates as follows: When one or more cabins 18 are immobilized on

  the section equipped with the rescue device, place the cha-

  rescue riot 26, moored to towing cable 36, on the

  cables 10, 12, for example at the height of the pylon 16. The saver

  teur 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. At the approach of the cabin trolley 24 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 overlapping position illustrated by FIGS. 5-7, and the rescuer couples the carriages 24, 26 by means of the bolts 50. He replaces the safety pins 58 and the guide rollers 52, 54

  and opens the clamps 20, for example by actuation and ver-

  rusting of the gripper control lever 63 (fig. 16). In re-

  starting 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 trolley 26, itself perfectly

  guided by the rollers 28-34 and guide 52, 54.

  The cables 10, 12 are centered in the open clamps 20,

  both lateral friction against the jaws. If more than one

  bines 18 are immobilized on the same section, the rescue is carried out successively by means of the same carriage.

  is equipped with a rescue device, which does not

  not terfere with the normal operation of the installation if care is taken to separate the rescue trolley 26 from the cables, 12 to allow the free passage of the cabins 18 and their

  cabin trolley 24. A towing cable 36 in a loop

  puts a rescue on sections having both ascending and descending slopes, the rescue trolley 26 being retained either by one or the other of the strands of the

towing cable 36.

  Different variant embodiments are shown on the

  following figures, the same reference numbers being used

  sés to designate identical or analogous elements. FIG. 2 shows a rescue device having a simple winch 64 with a drum, mounted on the pylon 16 ′ and the cable of which,

  attached to the rescue cart 26, constitutes the cable for

  masking 36. It is clear that this simplified device cannot be used on a section having slope reversals and that 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 there is no need to recall them. Figures 9 and 10 show a rescue device for a

  single cable gondola or chairlift with detachable clamps. The cat-

  riot cabin consists of a beam 66 carrying each

  one of its ends a disengageable clamp 20, the two clamps

  enclosing the same cable 10 in spaced locations.

  In an analogous manner 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 yokes

  safety 56, the single-cable rescue cart 68 being exact-

  half of the aforementioned rescue cart 26. A con-

  trepoids 70 balances the weight of the basket 60. After fixing the cabin trolley 66 to the rescue trolley 68 and after opening the clamps 20 the cabin 18 can be towed by the towing cable 36, the clamps 20 sliding on the cable 10

  and the cabin trolley 66 being perfectly guided by the cha-

  rescue riot 68. Cabin cart 66 can obviously

  have only one clamp or more.

  Referring to Figures 11 to 13, there is shown a rescue device according to the invention for a single cable installation with a single non-disengageable clamp 72. The rescue cart 74 is identical to the rescue cart 68 described above, but the legs link 46 are replaced by two callipers 76, 78 which, in the closed position, enclose the body of the

  clamp 72. Such a system can be used on a simple tele-

  seat, the fixed clamps of which can be easily opened and kept open during the sliding phase on the

cable immobilized.

  It is clear that the rescue device can be modified without departing from the scope of the invention, for example by postponing

  on the cabin trolley 24, 66, 72 certain guide elements

  dage, which can be put in place for the rescue operation or by at least partially reducing the load carried by the

  clamps open 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 spans the cabin trolley and carries at its end guide rollers cooperating with the cable. A frame of the cabin trolley is thus reconstituted by the

  rescue cart, but without passing from one to the other.

  In all these embodiments, it is essential that the rescue trolley 26, 68, 74 be perfectly guided to avoid any cross-over 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 avoids any jamming or risk of derailment of the carriage.

  cabin. The rescue cart must also provide the center

  trage cables 10, 12 between the jaws of the clamps 20 open, to prevent friction of the cables against these jaws during the shifting, friction which can cause 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

  this. On the rescue trolley 26 are articulated two arms, 82 parallel 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 ra-

  battered on the rescue trolley 26, that is to say an active position for coupling to the cabin trolley 24. In this coupling position the arms 80, 82 extend at the rear, in the extension of the rescue trolley 26 and frame the cabin carriage 24, to which they are coupled, as described

  above, by connecting lugs 46, 48, to form an

  seems rigid. The arms 80, 82 advantageously carry ga-

  guide lets 52, 54 framing the cables 10, 12 and improving

guidance.

  Certain features such as the counterweight 70 or others, described in relation to one of the embodiments can of course be used in the other embodiments and it is clear that the invention is not limited to the installations described.
