Definitions

  • the invention relates to a maintenance basket for cable cars, a cable car and a method for maintaining a cable car.
  • Cable cars transport cabins, chairs or other transport containers hanging on a rope between two locations.
  • the rope is preferably all-round.
  • the rope in particular the conveyor rope, is carried on batteries of rollers carried by support structures.
  • Fig. 1 and 2 show an example of a section of such a cable car with a rope 3, a support structure 1 and a battery of rollers 2.
  • the support structure 1 is designed here as a support pillar with a support shaft 11 and with a cross strut 12, also known as a yoke.
  • the support shaft 11 and/or the cross brace 12 can also be replaced by other support structures, such as a building or a rock.
  • the cross strut 12 preferably protrudes on two sides, so that a battery of rollers 2 can be stored on each extremity of the cross strut 12, on which the rope 3 is moved in different directions.
  • Support structures 1 often also have a lifting yoke 13 to which certain parts of the cable car, for example the cable 3, can be attached.
  • the roller battery 2 is an assembly that has a plurality of rollers 21 arranged one behind the other for guiding and securing the rope 3.
  • Roller batteries 2 carry the weight of a rope 3 and its hanger (up holder), press a rope 3 down (hold down holder) or combine these functions (change holder).
  • Fig. 1 and 2 show an example of a high holder, which can only be seen in detail in Fig. 1 shown while Fig. 2 the roller batteries 2 are only shown schematically as a square.
  • the roller battery 2 usually has a battery structure and rope pulleys or rollers 21, the rollers 21 being rotatably mounted in the battery structure, so that the rope 3 is guided on the rollers 21 of the roller battery 2.
  • the battery structure is usually mounted at one or at both ends of the cross strut 12 by means of a main axis 4, rotatable about a horizontal axis which runs at right angles to the cable direction.
  • the battery structure itself preferably has a main rocker 24 and a plurality of rockers 25, which are rotatably mounted on rocker axes 23 (preferably with the same axial direction as the main axis 4) in the main rocker 24.
  • the rockers 25 support the individual rollers 21 (or additional lower rockers) on corresponding roller axes 22.
  • the lowest rocker level preferably has two rollers 21.
  • the battery of rollers preferably has at least four rollers 21.
  • the roller battery 2 usually weighs more than 500 kg, often more than 1 or 2 tons, making it impossible for the roller battery to be moved and maintained by one person on site.
  • the maintenance of such a roller battery 2 includes the removal of all rotary axes, their cleaning and testing and the reinstallation of the rotary axes. To do this, the roller battery 2 must be removed from the support pillar 1 using a crane or helicopter to carry out this maintenance and then reinstalled on it. This also requires that the roller battery 2 is accessible from above, for which the rope 3 usually has to be removed from the rollers 21 of the roller battery 2 and moved inwards. This requires several hours of preparation for each pier, in addition to the high effort of transporting the roller battery.
  • EP2301819A2 , WO2015/003196 , EP2502799 show various maintenance baskets for the maintenance of a cable car, in particular EP2301819A2 and WO2015/003196 disclose a method for maintaining a reel battery.
  • EP0683079A1 and JPH02104374 show cable car vehicles for rescuing people.
  • this goal is achieved with a method for maintenance and a maintenance basket according to the independent claims.
  • a maintenance technician can move directly to the cable car maintenance point and carry out the necessary maintenance work on site. This eliminates the need for time-consuming disassembly and removal of maintenance parts such as the roller batteries.
  • the load of the roller battery By securing the load of the roller battery to a support structure of the cable car, the load of the roller battery, which is caused, for example, by its weight or by the cable of the cable car, can be removed from the axle so that it can be moved, cleaned and/or checked without having to transport the roller battery away.
  • This allows the load of the roller battery to be removed from the axle so that it can be cleaned and/or checked while the roller battery 2 or the main rocker 24 remains in the secured position.
  • the load is secured to a support yoke of the support structure.
  • the difference in height of the rope at the two attachment points can be compensated for with the two lifting mechanisms. This allows the maintenance technician located on the work platform to further adjust the height of the work platform to maintain the cable car so that he can reach the appropriate maintenance point.
  • the load is secured to a support yoke of the support structure.
  • a lifting mechanism is used to secure the load.
  • the lifting mechanism is configured to raise the position of the work platform relative to the maintenance basket structure.

  • the floor of the work platform is designed as a grating.
  • the maintenance basket has a crane.
  • the crane has a first support device, a second support device, a cross beam between the first and second support devices and a lifting mechanism attached to the cross beam, the crane being designed to be supported on the maintenance basket with the first support device and to be supported with the second support device on a support structure of the cable car.
  • the first support device is attached to a structure of the maintenance basket, which allows displacement of the mounted first support device in the cable direction.
  • the maintenance basket has a

  • the maintenance technician can be transported with the maintenance basket 5 to a next maintenance point, for example the next roller battery 2.
  • one or two of the following two maintenance steps are carried out: a cleaning and/or revision/testing of the main axis 4 and a cleaning and/or revision/testing of the remaining roller battery 2. If both maintenance steps are carried out, their order is important not matter.
  • the rope 3 is preferably secured with a securing device, preferably a hydraulic cylinder, on the support structure 1, preferably on the lifting yoke.

  • the rope is secured to the support structure 1 with a safety device above the main axis 4 and/or in the middle of the main rocker 24.
  • the rope 3 is only raised to such an extent that the rope 3 remains guided on the first and second sides of at least one of the rollers 21 mounted in the main rocker 24.

  • the main axis 4 is then pushed back completely into the recess 4 'of the main rocker 24 and the support structure 1.
