Prior art

Document FR2935945 describes a cable car of the same type comprising two taxiways each designed to allow the movement of a large capacity cabin back and forth between a departure station and an arrival station.

However, this installation is not suitable for moving a loop cabin on the two traffic lanes, which reduces the frequency of departures and therefore the rate of transport of people.

Statement of the invention

The object of the invention is therefore to remedy the aforementioned problems.

To this end, the invention relates to an overhead cable transport installation, comprising a departure station and an arrival station connected by cables defining two traffic lanes each consisting of two fixed and parallel carrying cables. one to the other and a traveling cable extending between the two carrying cables, the installation further comprising a carriage comprising two rolling elements each designed to cooperate with one of the carrying cables and means hooking designed to be coupled to the towing cable, said carriage further comprising two lateral uprights designed to cooperate with the rolling elements, a central upright designed to cooperate with the hooking means, and a crosspiece connecting the lateral uprights and the central upright between them, said installation comprising a vehicle suspended from the carriage to be moved along the traffic lanes, characterized in that that the cross member extends under the carrying cables and tractor, and in that the spacing between the lateral uprights is greater than the spacing between the supporting cables so that the lateral uprights cooperate with the rolling elements from the outside of the taxiway, each station comprising at least one pulley for returning the tractor cable designed to return the tractor cable from one taxiway to another.

The idea underlying the invention consists in using the particular arrangement of the upright and cross member assembly to leave free space above the carrying cables and tractor, and thus allow the return of the tractor cable to the station above the carriage like a detachable cable car.

Such a configuration allows here

The use of two closed-loop traffic lanes with seat and / or cabin type vehicles of small or large capacity.

The particular assembly of uprights and crosspiece according to the invention is also designed to prevent any fall of the vehicle in the event of derailment of one of the rolling elements of its carrying cable.

Description of the embodiment

The overhead cable transport installation according to the invention comprises a departure station 1 and an arrival station 1 partially shown in Figures la to le, connected by cables 2a and 2b defining two traffic lanes 3 for at least a suspended vehicle 4 of cabin type (small or large capacity) and / or chairlift.

Each traffic lane 3 is made up of two carrying cables 2a parallel to one another and fixed to one or more anchoring toms 5, here two tomme, and of a pulling cable 2b running between the two carrying cables 2a which is returned from one station 1 to another in a closed loop using a return pulley 6, in the manner of chairlift stations.

The anchoring toms 5 are here arranged in the center of each station 1 between the tractor cable 2b.

Each station 1 further includes first and second

paths guide 2 !the, 21b designed to move the 4 lane vehicle of traffic 3 to another to the square Cables por ters 2a and tractor 2b respect seriously deflected sure the tommes anchor 5 and the pulley 6. The first way of guide 21a replaces the cable carrier 2a extending on the outskirts from station 1 so that the second path of guide 21b replaces the cable carrier 2a extending at 1 inside the station 1 as visible on the face lb.

Each anchoring tomme 5 substantially overhangs the second guide path 21b in order to allow an upward deflection of the carrying cable 2a which it replaces so as to allow an anchoring of the two carrying cables 2a upwards.

The installation according to the invention also comprises carriages 7, shown in Figures 2a and 2b, each being connected to a vehicle 4 to allow its movement along a traffic lane.

A carriage 7 according to the invention here comprises two rolling elements 8, each comprising a plurality of rollers aligned one after the other designed to cooperate with one of the carrying cables 2a.

The carriage also comprises hooking means 9, of the mono-clamp or bi-clamp spring types, designed to be coupled by tightening to the tractor cable 2b of a traffic lane 3.

The carriage 7 further comprises two lateral uprights designed to cooperate with the rolling elements 8, a central upright 11 designed to cooperate with the hooking means 9, as well as a cross member 12 connecting the lateral uprights 10 and central 11 between them.

The cross member 12 extends under the supporting cables 2a and tractor 2b, and the spacing between the lateral uprights is greater than the spacing between the supporting cables 2a so that the lateral uprights 10 cooperate with the rolling elements 8 by the outside the taxiway 3.

Also, in order to avoid a crab movement of the vehicle on a traffic lane, the central upright is offset between the lateral uprights 10 in the manner of an asymmetrical W.

This configuration thus makes it possible to standardize and stabilize the traction of the vehicle 4 by the tractor cable 2b, by creating a traction point in the center of the two carrying cables 2a.

Each station 1 also includes a temporary disengagement system 13 of the attachment means 9 of the carriage 7, commonly known as the clutch ramp, disposed below the return pulley 6.

This system 13 is designed to disengage the attachment means 9 of the tractor cable lb so as to allow the insertion of the vehicle 4 from one traffic lane to another, in the manner of a disengageable system.

A deflection means 14 of cables 2a, 2b also makes it possible to deflect the tractor cable 2b from the temporary disengagement system 13 to the pulley 6 substantially continuously upwards, as can be seen in FIGS. 1a, 1b and 1c.

The pulley 6 is here oriented in the extension of the deflection of the tractor cable 2b so that the deflected tractor cable 2b and the pulley 6 extend in the same plane P.

The pulley is fixed here to two inclined beams 22 which extend towards the anchoring tomme.

The deflection means 14 thus limits the friction on the tractor cable 2b in order to reduce the power required to drive the tractor cable 2b in movement.

The installation according to the invention also comprises one or more pylons 15, for example a plurality of support and compression pylons, between the departure station 1 and the arrival station 1 which carry the carrying cables 2a and tractor 2b of the two tracks traffic 3.

A pylon 15 according to the invention comprises in particular for each taxiway 3 two suspended shoes 16 designed to support the carrying cables 2a and a pulley balance 17 between the shoes 16 designed to cooperate with the towing cable 2b.

The two hanging shoes 16 are here arranged to allow the displacement of the lateral uprights 10 of the carriage 7 from the outside of the circulation path 3.

It will be noted that when moving a vehicle 4 of the seat type, the use of a compression pylon may be required.

The installation according to the invention thus advantageously provides for a compression system 18 of carrying cable 2a, visible in FIG. 3, in the form of a guide rail, disposed in each shoe 16 of the compression pylon 15 in order to accommodate the carrier cable 2a and deflects it substantially towards the ground S.

A guide means 19, of section tube type, is also added to the shoe 16 to cooperate with the rollers of the rolling elements 8 of the carriage 7 in place of the carrying cable 2a during its deflection by the compression system 18.

The compression system 18 advantageously makes it possible to flatten the vehicle 4 towards the ground S while limiting the jolts and the vibrations when the vehicle 4 passes over the shoe 16.

Also, in order to further reduce the jolts and vibrations at the level of the shoe 16, the deflection of the carrying cable 2a by the compression system 18 follows the shape of the shoe 16, here substantially arched towards the ground S.

The ends of the shoe 16 are also substantially bent towards the ground S so as to catch up with the deflection of the carrying cable, which makes it possible to facilitate the arrival and the exit of the carriage 7 on the shoe 16.

Each shoe 16 further comprises a gutter 20, in the form of a half-tube, designed to guide the carrying cable 2a before and after its deviation by the compression system 18 so as to promote the transfer of the rolling elements 8 , of the tractor cable 2b on the guide means 19.

The particular half-tube shape of the gutter will thus prevent untimely derailments of the carrying cables 2a at the ends 16a and 16b of the shoe 16 when the strong winds cause the vehicle 4 to swing at the level of the pylon 15.
