Definitions

  • the invention relates to an overhead traveling cable transport installation, to which are disengaged clamps for loads, in particular cabins or seats, staggered along the line, the cabins being uncoupled from the cable at the entrance.
  • a station to travel on a transfer rail before being re-coupled to the cable at the exit of the station, the spacing of the cabins along the line being determined by the frequency of departures, and the circuit of circulation of the cabins in the station between the decoupling zone and the cable coupling zone with continuous cabin traffic (DE - A - 2 060 030).
  • Installations of the kind mentioned, in particular the detachable gondolas or chairlifts have the advantage of a distribution of loads along the cable and of boarding and disembarking of passengers at low speed.
  • the cabins are uncoupled from the cable, the latter running continuously at maximum constant speed.
  • the spacing of the cabins on the cable is fixed by the cadence or the rhythm of the departures at the start of the installation, but during operation shifts are inevitable and the installation no longer works under optimal conditions, in this case at regular and maximum flow. It is possible to remedy this drawback by building up a stock of cabins at the station, which compensates for irregularities and allows regular successive departures. This stock implies a stoppage of the cabins which is accompanied by unpleasant shocks and disturbs the regular functioning of the whole.
  • the object of the present invention is to allow the realization of a gondola, chairlift or similar installation with continuous operation in which the regular staggering of the cabins along the line is kept automatically for the entire duration of operation.
  • the installation according to the invention is characterized in that the circulation circuit of the cabins comprises a section equipped with a timing means capable of varying the travel time of said timing section by the cabins, to impose a regular rate of movement of the cabins .
  • the invention is based on the observation that the deviations occurring during a journey are relatively limited only the accumulation of these deviations being annoying and that these deviations can be compensated for by a simple timing device keeping the continuous circulation of the cabins in the station. .
  • a timing section is equipped with a first means for driving the cabs, for example at slow speed and with a second means at higher speed.
  • the cabin is propelled by the first means over the first half of the section, the second means catching up with the cabin and propelling it over the second half of the section.
  • the first means is arranged to allow this rapid drive, for example by adding a free wheel.
  • the journey time of the section is deduced from the speeds, slow during one half of the journey and faster during the other half.
  • the assembly is arranged so that a cabin having taken a maximum delay is caught up from the start of the timing section by the rapid drive means and moves over the entire section at high speed, thereby catching up on this delay. Conversely, a cabin in advance will be taken care of by the rapid drive at the end of the section traveled at slow speed. The cadence is restored with each passage of the rhythm section. In the aforementioned case, the rate is fixed by the rapid drive means, but the specialist will easily conceive a reverse operation where the clocking means will slow the movement.
  • the invention is described in the present specification as being applied to a monocable or bicable gondola, but it is applicable to any transporter with passive vehicles, in particular to detachable chairlifts, gondolas and the like.
  • the drive means can be of any type, identical or different, for example with fixed friction rollers, endless chains or belts, propulsion carriages, etc.
  • the timer is arranged at the arrival of the station, one of the drive means belonging to or being added to the retarder or decelerator device of the uncoupled cabs of the cable.
  • the last rollers of the roller train impose the slow speed of propulsion on the timing section.
  • the fast training can be achieved by a chain with training cleats extending along the course in the station in order to maintain the pace.
  • the spacing of the cleats determines the spacing between the cabins and therefore the rate.
  • the difference in speed between the two drive means results from a compromise of a minimum length of the timing section and a minimum of propulsion jolts.
  • a timing device can be arranged in each station to ensure a regular distribution on each of the strands of the cable, but in some installations the differences are small enough to require a single timer in one of the stations. According to the invention, the timer is then provided at the arrival of the least used strand to ensure a regular distribution on the most loaded strand.
  • the timing section coincides with or belongs to a speed-changing section, preferably of the cabin acceleration zone before coupling to the cable.
  • a deviation detector programs the acceleration cycle to compensate for this deviation and restore uniform distribution. This provision requires a more elaborate acceleration control but does not impose any traffic constraints in the stations.
  • an overhead cable 10 of a gondola extends between two end stations, passing through the stations on end pulleys 12, one of which drives the cable continuously.
  • the cable car shown is of the single cable type, the cable 10 being a carrier-tractor cable, but the invention applies to a two-cable installation as well as to chairlifts and cable-cars.
  • the cabins 14 are uncoupled from the cable 10 and run on a transfer rail 18 at reduced speed allowing passengers to disembark and embark.
  • the cabin 14 is accelerated by a gravity launching device or by positive drive, in particular with rollers 22, before being coupled to the cable 10. Only one of the stations is shown in FIG. 1, the other possibly being identical.
  • the deceleration of the cabin 14, uncoupled from the cable 10 at the inlet 16 of the station, is achieved by a train of rollers 24 frictionally engaging the carriage 26 for supporting the cabin 14.
  • a transfer chain 28 with cleats drive 30 extends along the transfer rail 18 in a closed circuit and is driven at a given speed by any means, for example a motor.
  • the chain 28 propels the stoppers 30 the cabins 14 on the rail 18 along the landing and boarding quays.
  • a gondola is well known and there is no need to describe it in more detail.
  • the last rollers of the deceleration train 24, for example the last four rollers 32, are driven at a constant speed V, and define a timing section C, along the decelerating section D proper, defined by the other rollers 24.
  • the chain 28 extends along the timing section C, the running speed V 2 being slightly higher than that V i imposed by the rollers 32.
  • the drive by the chain 28 has priority in the sense that the rollers 32, for example wheel free, are unable to oppose the driving of the cabin 14 at fast speed V 2 . It is easy to understand that the tabs 30 regularly distributed along the chain 28, traveling at continuous speed V 2 , regularly present the cabins 14 in the acceleration zone A to couple the cabins at regular spacing along the cable 10.
  • the cleat 30 catches up with the cabin before the half-way, possibly from the start of the timing section C if this delay is maximum.
  • the cabin crosses the entire section C at high speed V 2 by catching up.
  • a forward cabin travels at slow speed V i on the section C, the cleat 30 only catching up with it at the end of the journey in the extreme case (FIG. 4a, b).
  • the passage on the timing section C restores the regular distribution without stopping the cabs, the slight jerks when taken over by the cleat 30 can be amortized by any appropriate means.
  • the length of the timing section C is sufficient to compensate for the maximum deviations likely to occur and it is adapted to the admissible differential speed.
  • the combination of the timing section C and the decelerating section D facilitates the implementation of the invention, but it is obvious that the slow speed drive can result from any other means of propulsion.
  • the chain 28 has the advantage of perfect synchronism of the movements of all the cleats 30, but any other operating drive means can be used.
  • the cabin can be taken care of by another means of propulsion.
  • timing device which is preferably arranged at the arrival of the strand of the least used cable.
  • FIG. 5 represents an alternative embodiment of the invention
  • the timing section C is merged or included in the acceleration section A constituted by the train of rollers 22 driven in rotation by a electric motor 34 with variable speed controlled by a control unit 36.
  • FIG. 6 represents the curve of variation of the tangential speed of the rollers 22 and consequently of the speed of the cabin 14 accelerated as a function of the position “d” of this last on the AC section in normal operation.
  • a passage detector 38 of a cabin driven by the chain 28 which supplies a signal to the control unit 36.
  • the latter receives a timing signal by a clock 40 and generates a signal d 'deviation when the car is ahead or behind the timing signal.
  • the deviation signal modifies the control of the motor 34 to achieve an acceleration of the type shown in FIG. 7 in the event of delay, and of the type according to FIG. 8 in the event of advance.
  • the time required to travel the section A-C is obviously lower in the case of FIG. 7, where the acceleration occurs from the start of the section C, which allows catching up of the delay. In the case of FIG. 8, the acceleration takes place at the end in order to carry out the resetting in cadence.
  • a control rail 42 causes the clamp to be coupled to the cable 10, the cabins being regularly distributed.
  • Such a timer is preferably arranged at the outlet of the most used strand.
  • the timer can also be associated with the decelerator device 24, the realization arising from the previous presentation. This arrangement nevertheless requires an elaborate device for driving the decelerating rollers. It is also conceivable without departing from the scope of the invention to interpose, for example between the end of the chain 28 and the accelerator device an independent timer.
