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.
Description
- The invention relates to the implementation of a pneumatic or hydraulic telescopic system in the support towers and stations of the air transport installations by cable destined to passengers: Chairlifts, Gondolalifts and the like.
- Presently, such a transport installation comprises at least one tractor-transporter cable forming a ring between the departure and arrival stations, an undetermined number of chairs or cabins settled to the said movable cable with a predefined distance between them, a device of motorization to place the cable in rotation and some support towers of the cable along the route.
- The support towers generally comprise a concrete_foundation in the ground, a vertical structure fixed to the said concrete foundation and a horizontal structure with pulleys where the cable passes through with the chairs or cabins.
- The stations comprise at least a concrete pillar, where the station aisle is fixed, a motive wheel in case of the station motive, that is generally the departure station, and a wheel for inversing the direction of the cable in the station of return, which is generally the departure station.
- In the present prior art the abovementioned transport installation is at a constant height from the ground, normally considerable heights throughout the entire route. Therefore, under strong wind or stormy weather, the chairs or cabins are more exposed, compromising the security of users.
- Normally, these installations comprise equipment that makes them stop when the wind speeds ascends 60 km/h, compromising the security of users who are travelling along the route. In such situation, specialized rescue teams are obliged to intervene, always in complex and lasting maneuvers. Such situations might have ominous consequences for the intervening users and high costs for operating companies.
- In other cases, one cannot guarantee, in the beginning of each journey, safety conditions of the installations' operation. In this in case the installations do not pull out, which leads to the loss of income for the operating company.
- The aim of the invention is to solve the problems mentioned in paragraphs [005], [006] and [007].
- The object of the invention consists in the implementation of
-
- a pneumatic or hydraulic telescopic system in the support towers and motive and return stations;
- appropriate sensors in the chairs or cabins.
- This system allows the vehicles adjustment to several distances from the ground, being the entire installation able to follow the land's morphology, in order to withdraw the risks inherent to strong winds and to increase the users' security.
- However, if the installation can operate at a low height from the ground, the incidence of the wind in the chairs or cabins diminishes, thus increasing the users' security.
- However this system also facilitates the rescue of users if necessary, since with the pneumatic or hydraulic telescopic system enables the vehicles to be placed at ground level in any point of the course.
- Another advantage of the invention concerns the fact that, currently, one is not able to guarantee, in the beginning of each journey, the safety conditions throughout the whole course, being the case in some the ski resorts.
- In this case, the invention enables the installation to operate until the place where safety is guaranteed, creating for such a snow platform and lowering the installation to the required levels. In this way the loss of income is reduced for the operating company.
- One of the key elements of the invention is a pneumatic or hydraulic telescopic system that operates the support towers and stations to move in the ascending or descending direction according to the requirements.
- For an optimization and resistance of the pneumatic or hydraulic telescopic system, the cylinders that compose it must be manufactured in steel and there should be a protection or defense fuselage in the system. This fuselage will obligatory be telescopic to follow the movement of the system it contains inside.
- Another key element of the invention are the sensors to be placed in the chairs or cabins. In each chair or cabin two sensors are settled, one on the left side and the other on the right side of the vehicle, being both faced towards the direction of the route. Moreover the scanning angle of the sensors must enclose the whole width of the chairs or cabins.
- These sensors aim to detect the distance from ground along the course, when the installation is operating at considerable low levels, adjust the support towers to the adequate level and, consequently, ensure that no chair collides into an obstacle.
- The mechanical interaction between these two elements (telescopic system and sensors) is occurs in the following manner: the sensors detect an obstacle, send the information to the central office which, in its turn, activates the towers according to the predetermined directives and, consequently, the cable and the vehicles that it sustains.

fixed base 2A ofvertical structure 1 is attached to theconcrete foundation 3 by means of screws. The pneumatic or hydraulictelescopic system 2 receives at its end thehorizontal support structure 8 which contains in turn the pulleys 7 for a good sliding ofcable 6, thechairs 17 orcabins 19. - The
horizontal support structure 8 is attached to the pneumatic or hydraulictelescopic system 2 of thevertical structure 1 by means of a rabbet 9 and screws for a higher resistance. - This
horizontal structure 8 is altered at the level of pulleys 7, taking two rows of pulleys 7 instead of one, a superior row and an inferior row lined, becausecable 6 passes between them. So being, when it becomes necessary to raise orlower towers 10, thecable 6 which runs between both rows of pulleys 7, is submitted to a certain pressure, either by the inferior or the superior pulleys 7, following the movement oftowers 10. Consequently, it becomes rather improbable forcable 6 to be released. - As previously described in paragraph [016], the pneumatic or hydraulic
telescopic system 2 must have aprotection fuselage 5. Thisfuselage 5, also telescopic, must be in steel alloy in cylindrical and hollow form. Thecylinder 5A operates outside thefixed base 2A and thecylinder 5B operates outside thecylinder 5A. However, thecylinder 5C operates theinside cylinder 5B and thus successively. All fuselage works in a rail. - However the
installation 20 must operate together, as a whole, both in the ascending and descending direction, or with the flexibility allowed by the tension ofcable 6. - The tension of
cable 6 can be compensated with the implementation of the pneumatic or hydraulictelescopic system 2 instations - In

telescopic system 2 does not require the same dimensions as thesupport 10, since the task of thetelescopic system 2 instations cable 6 thus elevating or lowering them when necessary.
