FR2528781A1 - Rapid transit type ski lift - moved on pulsed system in trains made of groups of vehicles - Google Patents

Abstract

The teleski has a number (K) of trains (4) in (L) groups (5) of (N) vehicles (6), fixed together by a cable held between a driven pulley and a return one. It is used for transporting ski personnel or material. The movement is of a pulsed type, following a cycle determined as a function of the variables (K), (L) and (N) to obtain higher or lower fixed load and speed conditions. The symmetrical layout allows simultaneous embarkation of all vehicles at reduced speed, in a train group, or disembarcation in series of all vehicles at one point.

Description

 The present invention relates to a transport device for transporting people, skiers or equipment from one point to another without limitation of length or drop.

 In ccnnus systems of this type, such as conventional two-person three-seater chairlifts, the vehicles are distributed equally along the line whose speed is constant.

 These assemblies thus designed require significant infrastructure as well as a large number of vehicles ensuring a very average flow for a high cost of the installations.

 In addition, transport speeds are relatively slow, and boarding and disembarking pose many problems.

 Some of these devices, in order to overcome these drawbacks, include declutching and clutch systems in the end stations, but their complexity requires maintenance and permanent monitoring for reliability despite reduced performance.

 The object of the invention makes it possible to eliminate these faults while providing more practical possibilities as well as better operational safety.

 Otherwise. at equal speed and length, the transfer time is much shorter than in the case of a device at constant speed.

 On the other hand. at equal speed, the number of people or skiers in line being reduced, this considerably facilitates evacuation, in the event of untimely stopping.

 The apparatus is presented in the conventional form of a teleported vehicle whose vehicles are distributed in groups along the line according to the flow and speed arrangements chosen.

 your other characteristics are identical, in particular in terms of fixed attachments, drive or return pulleys, as well as the variable speed drive kinematic chain. Motor skills can be obtained either by gearmotor or by hydrostatic transmission.

 TP1, which is schematically shown on board I, FIG. 1, the device comprises an endless cable (1) stretched between a driving pulley (2) and a deflection device (3), the tensioning system being able to be carried out hydraulically or by counterweight on one side or the other.

@ A series of intermediate pylons. in support or compression,
can be inserted in the line following the profile.

 In order to obtain the desired flow rates and according to the languors of the devices, a number K of trains (4) of groups (5) of n vehicles (6) are symmetrically fixed by means of fasteners.

 The values of k, α and n are variable and determined so as to obtain an optimum yield.

 The pulsation cycle of the device is a function of the position of the different trains Icng of the cable bcucle (1).

 'This arrangement allows simultaneously; both boarding at reduced speed of all vehicles (6) of a group (5) of a train (4) as well as disembarking, either in series of all vehicles (6) at a given point, or in parallel on an area specific to each.

 The boarding area - board I (Figure 2) - includes a series of pipeline barriers (7) and automatic gates (8) regulating access to vehicles.

 A materialized landing area, visualized w automated, is set up according to the series or parallel option chosen.

 The device which is the subject of the invention can be applied in numerous fields for the transport of people and in particular of skiers.

 Its great possibilities of adaptation as well as its flexibility of operation must allow its use in order to solve all the problems relating to this type of material.

 Particularly interesting applications can be provided for mechanical lifts, especially in the case of high-speed chairlifts of considerable length.
