FR2823482A1 - Cableway transport system support and guide has two sets of rollers on curved beam pivoted to pylon - Google Patents

Abstract

The cable support and guide for a transport system with two overhead support and traction cables (15) consists of two sets of rollers (7) pivoted to a curved beam set in a vertical plane and pivoted by a bracket (2) to the top of a pylon. The curved beam has two vertical flanges, with the rollers located between them, and has one or more pairs of end rollers (8) mounted on a balance arm (9) with its pivot (10) fixed to the beam, and counter-rollers (14) opposite the end rollers.

TRANSPORT SYSTEM.

  The present invention relates to a support and guiding device for a cable for a cabin transport system, and more particularly to a system with two carrying cables and

r ra cte u rs.

  o We already know such devices in which rollers are mounted two by two at the two ends of elementary pendulums, two successive pendulums themselves being mounted on a support pendulum, and so on so

  forming trains of long articulated rollers.

  Although generally satisfactory, these devices have the disadvantage of a certain transverse flexibility

  which affects their performance in strong side winds.

  The present invention aims to overcome these drawbacks.

  More particularly, the invention aims to provide a support and guide device for a transport system cable, which allows the operation of this system even in

  strong wind, including side wind.

  To this end, the invention relates to a support and guide device for a cable for a cabin transport system with two carrying cables and tractors, characterized in that it comprises two sets of rollers mounted each pivoting on a curved beam substantially contained in a vertical plane, and means of articulation of each of said

  beams on a pylon, rotating in said plane.

  This gives a much more rigid assembly, especially transversely, and therefore less sensitive to winds

especially lateral.

  In a particular embodiment, said beam is composed of two flanges between which the rollers are mounted. Also in a particular embodiment, at least two rollers located at at least one end of said beam are mounted on a pendulum itself mounted in rotation

  around an axis fixed to said beam.

  These cable entry and / or outlet balances allow a good adaptation of the support and guide device in the case where the cable entry and / or exit angle is caused to vary, in particular under the effect of variations of

load of the transport system.

  Also in a particular embodiment, the device according to the invention may comprise at least one counter-roller facing at least one end roller, and elastic means for supporting said counter-roller on the respective cable. More particularly, it is possible to provide at least two counter rollers mounted on a balance opposite the balance

roller support.

  o The device also comprises, in a particular embodiment, two cable retention units each located

  adjacent to one of the cables on its side opposite the other cable.

  A particular embodiment of the invention will now be described by way of nonlimiting examples with reference to the appended schematic drawings in which: - Figure 1 is a front view of a pylon comprising support and guiding devices according to the 'invention; Figure 2 is a side view; to - Figure 3 is an enlarged view of such a device; Figure 4 is a sectional view along line 4.4. of Figure 3; and Figure 5 is a front view of the holding assembly

  of a cabin for the passage of a device according to the invention.

  We see in Figures 1 and 2, a pylon 1 made in any known manner o supporting, by means of supports 2 hinged in 3 (Figure 3) at the top of the pylon 1, a set of curved beams 4 forming two by two one device

  support and guide according to the invention.

  s Each beam 4 is formed by two lateral flanges 5 and 6 between which are pivotally mounted a set of

rollers 7.

  At each end of the beam, two rollers 8 have their axis mounted on a balance 9 itself articulated at 10 between the

flanges 5 and 6.

  Also at each end of the beam, a bracket 11 supports by means of a spring 12 an articulated balance 13 on which are mounted two counter-rollers l facing the rollers 8 or slightly offset with respect to these rollers. s The cable 15 passes successively between the input rollers 8 and the input counter-rollers 14, then on each roller 7, and finally between the output rollers 8 and the output counter-rollers 1 4. to A certain variation in entry and exit angles is

  permitted due to the existence of pendulums 9 and 13.

  We see in Figure 5, the structure 16 of a cabin on which is mounted two clamps 17 each for clamping a

  s cable 15, 15 'so as to support and tow the cabin.

  Two stops 18 form cable retention units

  to avoid its derailment.

  The two stops 18 are mounted outside the device

  against the cable, on its side opposite the other cable.

  The derailment is nevertheless prevented on each side of the rollers because the structure 16 and the clamps 17 maintain

The spacing between the cables.
