Definitions

  • the invention relates to a method for maintaining a cable car.
  • Cable cars transport cabins, chairs or other transport containers suspended from a rope between two locations.
  • the rope is preferably continuous.
  • the rope in particular the haul rope, is carried on roller batteries supported 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 roller battery 2.
  • the support structure 1 is designed here as a support pillar with a support shaft 11 and a cross brace 12, also called 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 brace 12 preferably protrudes on two sides, so that a roller battery 2 can be mounted on each extremity of the cross brace 12, on which the cable 3 is moved in different directions.
  • Support structures 1 often also have a lifting yoke 13, to which certain parts of the cable car, e.g. 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 downwards (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, wherein the rollers 21 are 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 rotatable by means of a main axis 4 about a horizontal axis, which runs at right angles to the cable direction, mounted at one or both ends of the cross strut 12.
  • the battery structure itself 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 other sub-rockers) on corresponding roller axes 22.
  • the lowest rocker level has two rollers 21.
  • the roller battery 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 one person on site to move and maintain the roller battery. Maintenance of such a roller battery 2 involves removing all the rotary axes, cleaning and checking them, and reinstalling the rotary axes. To do this, the roller battery 2 must be removed from the support pillar 1 using a crane or helicopter in order 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 must usually be removed from the rollers 21 of the roller battery 2 and moved inwards. In addition to the high effort involved in transporting the roller battery, this requires several hours of preparation for each pillar.
  • 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 roller battery.
  • EP0683079A1 and JPH02104374 show cable car vehicles for passenger rescue.
  • 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 e.g. by its weight or by the cable of the cable car, can be taken off the axle so that it can be moved, cleaned and/or inspected without having to transport the roller battery. This allows the load of the roller battery to be taken off the axle so that it can be cleaned and/or inspected 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.
  • a lifting mechanism is used to secure the load.
  • the maintenance cage has a lifting mechanism with which the height of the work platform can be adjusted relative to the rest of the maintenance cage. This allows the maintenance technician on the work platform to adjust the height of the work platform to maintain the cable car so that he can reach the corresponding maintenance point.
  • the lifting mechanism has two lifting mechanisms. This allows the height of two sides of the work platform to be adjusted differently.
  • the maintenance basket has two hanging devices for hanging the maintenance basket from two attachment points on the rope.
  • This has the advantage that the work platform can be made large enough for the necessary maintenance work and still hangs stably from the rope.
  • This embodiment is particularly advantageous in combination with the two lifting mechanisms, as this allows the height difference of the rope at the two attachment points to be compensated for with the two lifting mechanisms.
  • the lifting mechanism is configured to raise the position of the work platform relative to the maintenance basket structure.
  • the maintenance basket structure is connected between the first lifting mechanism and the second lifting mechanism only via the height-adjustable work platform.
  • the first lifting mechanism comprises a rope-like structure connecting the work platform to the first hanging device and a mechanism for adjusting the length of the rope-like structure to adjust the distance between the first hanging device and the work platform
  • the second lifting mechanism comprises a rope-like structure connecting the work platform to the second hanging device and a mechanism for adjusting the length of the rope-like structure to adjust the distance between the first hanging device and the work platform.
  • the rope-like structure of the first and second lifting mechanism each has two rope-like substructures.
  • the four rope-like substructures support the work platform at the four corners.
  • the work platform is mounted on a lifting carriage of each lifting mechanism so that the work platform can rotate about a horizontal axis which is perpendicular to the connecting line is arranged between the first attachment point and the second attachment point.
  • the first hanging device and/or the second hanging device enable rotation of the work platform about a vertical axis.
  • the maintenance basket is designed to move the work platform horizontally and perpendicular to the rope direction.
  • 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 member between the first and second support devices and a lifting mechanism attached to the cross member, wherein the crane is designed to be supported on the maintenance cage with the first support device and to be supported on a support structure of the cable car with the second support device.
  • the first support device is mounted on a structure of the maintenance basket, which allows a displacement of the mounted first support device in the rope direction.
  • the maintenance basket has a testing device for magnetic inductive material testing.
  • the maintenance basket has a small parts cleaner with a grease-dissolving cleaning fluid.
  • the maintenance work comprises the following steps: rotating a main rocker of the roller battery about an axis that supports the main rocker so that the rope is lifted from rollers mounted in a first side of the main rocker; cleaning and/or checking and/or replacing the axes, plain bearings, rockers and/or rollers mounted in the first side of the main rocker; rotating the main rocker of the roller battery about an axis which supports the main rocker so that the rope is lifted off rollers mounted in a second side of the main rocker opposite the first side; and cleaning and/or checking and/or replacing the axes, plain bearings, rockers and/or rollers mounted in the second side of the main rocker.
  • cleaning and/or checking and/or replacing the axles, plain bearings, rockers and/or rollers mounted in one side of the main rocker comprises securing the rocker mounted on that side with a crane supported on the work platform.
  • a maintenance basket that can transport a maintenance technician to a maintenance point on the cable car.
  • Fig. 3, 4 , 5 and 6 show an embodiment of such a maintenance basket 5.
  • the maintenance basket 5 has a maintenance basket structure, a hanging device 6 and a work platform 8.

  • This fastening mechanism 62 can be, for example, a flange or an opening into which the hanging rod can be inserted and fastened, or any other fastening mechanism.
