Prior art

The document FR2935945 describes a cable car of the same type comprising two traffic lanes 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 cab in a loop on the two lanes of traffic which reduces the frequency of departures and therefore the rate of passenger transport. The documents JPH01160774A and EP0663328A1 also describe similar aerial cable transport installations.

Disclosure of the invention

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

To this end, the invention relates to an aerial cable transport installation according to claim 1.

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

Such a configuration here allows the use of two closed-loop traffic lanes with vehicles of seat types and / or of small or large capacity cabin types.

The particular upright and cross member assembly 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.

Indeed, the spacing between the carrying cable and the towing cable is sufficient to maintain good grip of the vehicle and limit its angulation.

The vehicle according to the invention thus remains must be suspended by at least one carrying cable and the towing cable and prevent the slipping of the transported persons.

Description of the embodiment

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

Each traffic lane 3 is made up of two supporting cables 2a parallel to one another and fixed to one or more anchoring posts 5, here two tomes, and of a sliding towing cable 2b extending 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 posts 5 are here arranged in the center of each station 1 between the towing cable 2b.

Each station 1 further comprises first and second guide paths 21a, 21b designed to move the vehicle 4 from one traffic lane 3 to another instead of the carrying cables 2a and tractor 2b respectively deflected on the anchor posts. 5 and pulley 6.

The first guide path 21a replaces the carrier cable 2a extending to the periphery of the station 1 while the second guide path 21b replaces the carrier cable 2a extending inside the station 1, as can be seen in the figure. figure 1b .

Each anchor 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 anchoring of the two carrying cables 2a upwards.

The installation according to the invention also comprises carriages 7, shown in the 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 single-clamp or bi-clamp type with spring, designed to be coupled by clamping to the towing cable 2b a traffic lane 3.

The carriage 7 further comprises two lateral uprights 10 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 10 and central uprights 11 to each other. .

The crossmember 12 extends under the carrier cables 2a and tractor 2b, and the spacing between the side uprights 10 is greater than the spacing between the carrier cables 2a so that the side uprights 10 cooperate with the rolling elements 8 by l 'outside the traffic lane 3.

Also, in order to avoid a crabbing movement of the vehicle on a traffic lane, the central upright 11 is eccentric between the lateral uprights 10 in the manner of an asymmetric W.

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

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

This system 13 is designed to disengage the hooking means 9 from the tractor cable 1b 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 towing cable 2b from the temporary disengagement system 13 to the pulley 6 in a substantially continuous upward manner, as visible in Figures la, 1b and 1c.

The pulley 6 is here oriented in the extension of the deflection of the towing cable 2b so that the deflected towing 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 anchor posts.

The deflection means 14 thus limits the friction on the towing cable 2b in order to reduce the power required to drive the towing 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 traffic lane 3 two suspended shoes 16 designed to support the supporting cables 2a and a pulley balancer 17 between the shoes 16 designed to cooperate with the towing cable 2b.

The two suspended shoes 16 are here arranged to allow the displacement of the lateral uprights 10 of the carriage 7 from the outside of the traffic lane 3.

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

The installation according to the invention thus advantageously provides a compression system 18 of the carrying cable 2a, visible on the figure 3 , in the form of a guide rail, arranged in each shoe 16 of the compression pylon 15 in order to accommodate the carrier cable 2a and the deviate appreciably towards the ground S.

A guide means 19, of the 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 carrier cable 2a during its deflection by the compression system 18.

The compression system 18 advantageously makes it possible to press the vehicle 4 towards the ground S while limiting the jolts and 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 shoe 16 are also substantially curved 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 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 supporting cable 2a before and after its deflection 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 supporting 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.
