Pneumatic or Hydraulic Telescopic System For Pylons or Chair Lift Stations, Gondola Lifts and the Like

Abstract

The invention concerns a pneumatic or hydraulic telescopic system comprising cylinders concentric at several diameters inserted in the vertical structure of the support pylons ( 1 ) and in the departure and arrival stations ( 14, 16 ), between the concrete pillar ( 1 ) and the nave of the station ( 15 ). The sensors are applied on either side of the vehicles ( 17, 19 ), facing their forward movement direction, having a reading angle including the entire width of the vehicles. The pneumatic or hydraulic telescopic system ( 2 ) is operable: in the support pylons, to adapt the vehicles at the appropriate levels as they travel, causing them to rise or drop depending on the contour of the terrain; in the stations, to compensate the tension of the cable if required. The sensors ( 18 ) are operable to analyze the contour of the terrain and inform the control center to actuate the system in accordance with the requirements. Such an overhead cable installation for transporting passengers with said novel elements can operate at different heights relative to the ground.

1 . Pneumatic or hydraulic telescopic system for chairlifts, gondola lifts and the like including a transport installation comprising:
 at least one tractor-transporter cable forming a ring between the departure station and arrival station;   a plurality of chairs or cabins fixed to the said cable at a predefined distance between them;   a device of motorization to place the cable in rotation and several support towers of the cable along the course;   comprising a pneumatic or hydraulic telescopic system, which lowers and raises the vehicles according to the instructions of the operator, consisting of concentric cylinders of various diameters, in the towers of support, in the departure station and arrival station, and sensors that detect the level of the land so that the chairs and cabins do not shock with obstacles.   
   
   
       2 . Pneumatic or hydraulic telescopic system for chairlifts, gondola lifts and the like according to  claim 1  comprising a pneumatic or hydraulic telescopic system in support towers with a fuselage of cylindrical protection, hollow and also telescopic, which receives in its upper end a horizontal support structure with two rows of pulleys and a cable that passes between the said rows of pulleys in order to settle the cable between them not letting it be released, when the support towers are in an ascending or descending movement. 
   
   
       3 . Pneumatic or hydraulic telescopic system for chairlifts gondola lifts and the like according to  claim 1  comprising a pneumatic or hydraulic telescopic system in which the cylinder of the base is immovable and fixed to the concrete foundation through a setting with screws and the horizontal structure of support is attached to the pneumatic or hydraulic telescopic system through a setting for rabbet and with screws for a higher resistance. 
   
   
       4 . Pneumatic or hydraulic telescopic system for chairlifts gondola lifts and the like according to  claim 1  wherein, in stations of traction and return, the pneumatic or hydraulic telescopic system is placed between the pillar or concrete pillars and the structure, that sustains the aisle, and is attached to the said structure through a setting in U and screws with the measures required by the structure. 
   
   
       5 . Pneumatic or hydraulic telescopic system for chairlifts gondola lifts and the like according to  claim 1  wherein it is attached in the upper end of the concrete pillar with the same technical procedure as the pneumatic or hydraulic telescopic system is fixed to the concrete foundation. 
   
   
       6 . Pneumatic or hydraulic telescopic system for chairlifts gondola lifts and the like according to  claim 1  wherein the transport installation is formed by a pneumatic or hydraulic telescopic system inserted in the support towers and in the traction and return stations, in order to elevate or lower the support towers according to the necessities. 
   
   
       7 . Pneumatic or hydraulic telescopic system for chairlifts gondola lifts and the like according to  claim 1  wherein the transport installation comprises sensors placed in the chairs or cabins, whose function is to detect the level of the land or eventual obstacles along the course, when the installation is operating at considerable low distances from the ground and to adjust the support towers at the adequate level. 
   
   
       8 . Pneumatic or hydraulic telescopic system for chairlifts gondola lifts and the like according to  claim 1  wherein two sensors are placed in the vehicles, one on the left side and the other on the right side, facing towards the direction of the route. 
   
   
       9 . Pneumatic or hydraulic telescopic system for chairlifts gondola lifts and the like according to  claim 1  wherein the scanning angle of the sensors encloses the whole width of the chairs or cabins. 
   
   
       10 . Pneumatic or hydraulic telescopic system for chairlifts gondola lifts and the like according to  claim 1  wherein in the detection of some obstacle, the sensors send the information to the central office and this, in its turn, activates the support towers and adjusts them according to programmed directives and, consequently, the cable and the vehicles that it sustains.
