Definitions

  • the invention relates to an air transport installation with two carrying cables and tractors.
  • Such installations with two tractor-carrying cables have many advantages, in particular the possibility of significant timing and increased capacity of the vehicles (hence greater flow in passengers or materials) and better lateral stability of the vehicles (wind resistance).
  • the fact that the vehicles are disengageably associated with the cables makes it possible to disengage the vehicles from the cables in the embarkation / disembarkation stations, in order to reduce their speed without modifying that of the cables, or even to store them in the station and then re-engage them between the cables if necessary. You can also easily adapt the number of vehicles online as needed.
  • French patent 1,249,949 describes an installation in which the vehicles are associated with the cables by clamps gripping the cables from below. The uncoupling is therefore done naturally by opening the clamps, and the vehicles are diverted from the cables simply by descending. Such an installation is fictitious, because the reliability of the association of vehicles with cables is not ensured, because the weight tends to open the clamp and to cause untimely uncoupling.
  • French patents 2,525,981 and European patents 093,680 describe an installation in which the clamps are, conventionally, more secure, resting on the upper face of the cables.
  • cable guide rollers are provided which modify the spacing of these cables to allow disengagement of the vehicle and its movement on independent cable transfer rails.
  • This solution is also not satisfactory. Indeed, the cables which are carrier-tractors, are of large diameter and highly stretched. Consequently, installing cable deflection rollers to modify the cable spacing is not only technically extremely delicate, but also poses safety problems, since the cables are then subjected to improperly controlled stresses and can all the more easily escape from the pebbles. This must in any case be avoided at embarkation / disembarkation stations. In addition, the risk of derailment is proportional to the number of deflection rollers in an installation.
  • EP-A 0 263 035 (published on 06.04.88 and not belonging to the state of the art) already teaches that it is possible to offset two end pulleys cooperating respectively with each cable for clear vehicles. However, this longitudinal offset increases the congestion of the stations too strongly.
  • the embarkation / disembarkation stations of these known installations are too bulky and require a space on the ground which is not always available, especially in the mountains.
  • the spacing of the arrival and departure traffic lanes in a station is limited and imposed by the diameter of the end pulleys. It is also desirable in certain cases (for example, disturbed reliefs at the location of stations) that the arrival traffic lane is not coplanar with the departure traffic lane in a station.
  • the end pulleys of the two cable loops must be as close as possible to each other, to simplify the tensioning and drive mechanisms which are essential elements in installations with two carrier cables . None of the known installations can meet these requirements.
  • the invention aims to remedy the aforementioned drawbacks of known installations and relates to an air transport installation in which the spacing of the cables remains constant along the line and relatively small (that is to say less than the size).
  • transverse of vehicles typically from 0.5 m to 3 m, in particular 0.75 m and 1.4 m); the clamps come to bear on the upper part of the cables; vehicles can simply be disengaged from cables in end stations without compromising the reliability of the installation (the risks of derailment being minimized), nor increasing the cost.
  • the invention also aims to reduce the size and volume of a boarding / disembarking station of such an installation; allow to choose at will the spacing of traffic lanes, in particular spacings greater than those of known installations; allow non-coplanar arrival and departure traffic lanes to be created in a station; and be able to bring the end pulleys of the two cable loops closer to each other.
  • the invention therefore provides an air transport installation with two carrier-tractor cables, comprising firstly two carrier cables- substantially parallel, continuously scrolling tractors, forming two endless loops passing over drive end, guide, return or tensioning pulleys located in embarkation / disembarkation end stations, second place at least one and generally several vehicles provided with disengageable clamps for tightening the cables, thirdly means for disengaging and clutching the clamps and means for supporting / guiding the vehicles located in the loading / unloading stations.
  • the vehicles are engaged between, driven and carried by the cables, and that in the embarkation / disembarkation stations, the vehicles are completely disengaged and dissociated from the cables, characterized in that in at least one embarkation / disembarkation station, for the arrival route and for the departure route defined by the cables, the respective cooperation zones of a cable, with the end pulleys in the arrival / departure paths are offset longitudinally with respect to the cooperation zones of the other cable with the end pulleys so that a longitudinal free space is provided between the parts respective of the most extreme cable loops with respect to the station, in that at least one return pulley of at least one loop formed by a cable is set back towards the interior of the vehicle traffic line, guide means causing the cable to make a half-turn upstream and downstream of the return pulley, in that at least one return pulley of at least one loop formed by a cable is substantially parallel to the arrival path and / or to the starting lane while being in a different plane.
  • At least one return pulley of at least one loop formed by a cable, located in the most extreme position relative to this loop and separating the cable entry and departure paths, is of a diameter different from - notably less than - the lateral distance separating the arrival lane and the departure lane.
  • the guide pulleys to a return pulley have inclined axes.
  • the spacing of the two cables is kept constant upstream and downstream of the end pulleys, and no cable deflection roller for modifying their spacing is placed at the inlet, at the outlet or between the end pulleys.
  • Transport security is therefore greatly improved compared to the prior art.
  • the disengagement / engagement of vehicles between / between the cables is simple and safe, no special device being necessary on the vehicles or the trolleys. We also have the choice of carrying out the disengagement and the engagement up or down.
  • stations can be installed almost anywhere and whatever the terrain, and carry out simply and economically the tensioning and the driving of the two cables in synchronism thanks to the devices known for this purpose.
