AI Technical Summary
In cable car systems, maintenance or repair work poses a significant risk to operating personnel due to the movement of cable car vehicles, especially when lubrication of sliding bearings is required during operation, as they are exposed to danger near moving vehicles.
An input device on the cable car support signals the control unit to reduce the speed of approaching cable car vehicles, activating optical and acoustic warnings for personnel and controlling the traction cable's speed to ensure safe passage during maintenance, allowing vehicles to be stopped or moved at reduced speeds near the work area.
This method significantly reduces the risk to operating personnel by ensuring safe working conditions during maintenance or repair by slowing or stopping cable car vehicles near the work area, thereby protecting them from hazards.
Abstract
Description
[0001] The present invention relates to a method for operating a cable car system with at least two cable car stations and with at least one closed haul rope running between the cable car stations, to which at least one cable car vehicle is coupled, or with at least one track rope on which at least one cable car vehicle is moved by means of at least one haul rope, wherein the at least one cable car vehicle is moved between the cable car stations by means of the haul rope or the haul rope, and with at least one cable car support over which the haul rope or the track rope and the haul rope are guided, wherein the travel positions of the at least one cable car vehicle along the travel routes are determined by means of at least one measuring device, and wherein the travel positions of the at least one cable car vehicle along the travel routes are transmitted to a control unit and processed and stored therein.
[0002] The present invention further relates to a cable car system for carrying out this operating method.
[0003] Such a method for operating a cableway system and such a cableway system are known, for example, from AT 411 982 B.
[0004] In cable car systems, maintenance and repair work is required along the route of the cable car vehicles, often even while the system is in operation. This is particularly true for cable car systems with track cables, on which the cable car vehicles are moved by haul ropes. In these systems, the sliding bearings for the track cables, located on the support towers, need to be lubricated during operation. During such maintenance and repair work, the operating personnel, who are located near or within the operating areas of the cable car vehicles, are exposed to significant dangers due to the vehicles themselves.
[0005] The present invention is based on the objective of creating an operating method that significantly reduces this hazard. According to the invention, this is achieved by means of an input device located on the at least one cable car support, which sends a signal to the control unit indicating that maintenance or assembly work, etc., is to be carried out on this cable car support. When a cable car approaches the support, the control unit regulates the drive for the movement of the at least one cable car such that the cable car moves at a significantly reduced speed compared to its operating speed in the vicinity of the support or is brought to a stop.
[0006] In a cableway system for carrying out this operating procedure with at least two cableway stations and with at least one self-contained haul rope running between them, to which at least one cableway vehicle is uncoupled, or with at least one track rope on which at least one cableway vehicle can be moved by means of at least one haul rope, wherein the at least one cableway vehicle is moved by means of the haul rope orthe haul rope is movable between the cable car stations, and with at least one cable car support over which the haul rope or the track rope and the haul rope are guided, wherein a measuring device is provided by means of which the travel positions of the at least one cable car vehicle along the travel routes can be determined, and wherein a control unit is further provided to which the travel positions of the at least one cable car vehicle along the travel routes can be transmitted and processed and stored, according to the invention an input device is provided on the at least one cable car support by which a signal can be input into the control unit indicating that maintenance or assembly work etc. is to be carried out on this cable car support.This is carried out by configuring the control unit so that, when a cable car vehicle approaches the cable car support, the drive for the movement of the at least one cable car vehicle can be controlled in such a way that it is moved in the area of the cable car support at a speed greatly reduced compared to the operating speed or is stopped.
[0007] Preferably, the at least one cable car is equipped with an optical and / or acoustic signal transmitter, which is activated by the control unit as soon as the cable car approaches the cable car support tower. Furthermore, the device for determining the operating position of the at least one cable car is formed by at least one measuring device located in one of the cable car stations. The operating method according to the invention, or a cable car system for carrying out this method, is explained in more detail below with reference to an embodiment illustrated in the drawing. The drawing shows: FIG. 1 a section of a cable car system with a cable car station, a cable car support and a cable car vehicle which can be moved on a track cable by means of a haul rope, FIG. 2 a deflection pulley for the haul rope, in axonometric representation, as well as a block diagram with a control unit, and FIG. 3 a cable car vehicle which can be moved in the cable car system, in side view.
[0008] In FIG.1 Figure 1 shows a section of a cable car system 1 with a cable car station 11 and a cable car support 12. Between cable car station 11 and another cable car station (not shown) is a track cable 13, which is anchored in the cable car stations and runs over the cable car support 12. Cable car vehicles 15 can be moved along the track cable 13 by means of a haul rope 14. The haul rope 14, which is closed and guided over cable deflection pulleys and cable deflection pulleys in the cable car stations, is moved in a loop at a speed of, for example, 7 m / sec. In the cable car stations, the cable car vehicles 15 are uncoupled from the haul rope 14, moved through the respective cable car station, where passengers board or disembark, and subsequently recoupled to the haul rope 14, after which they are moved to the other cable car station.
[0009] Instead of a carrying cable and a haul rope, a haul rope can be provided, to which cable car vehicles 15 are coupled.
[0010] In order to ensure that this cable car system operates in accordance with the technical requirements, the movement speeds of the at least one haul rope 14 and the at least one transport rope, and thus the travel speeds of the cable car vehicles 15, and the travel positions of the cable car vehicles 15 are determined and stored at all times during operation.
[0011] As this is in FIG.2 As shown, the haul rope 14 is guided around a cable deflection pulley 2 in the cable car station 11. Since the haul rope 14 is also guided around a deflection pulley in the other cable car station, it can be moved in a loop. The haul rope 14 is equipped with at least one measuring device 3, which measures the respective speeds of the haul rope 14 and its travel lengths. This allows the operating positions of the cable car vehicles 15 coupled to the haul rope 14, and thus their distances to the cable car station 11 or to the cable car support 12, to be determined at any time.
[0012] A control unit 4 is provided for controlling the cable car system. The data on the movement sequences, acquired by the measuring device 3, are entered into this unit via lines 31, processed, and stored there. Input devices 5 are provided in those areas of the cable car system where maintenance or assembly work needs to be carried out, e.g., at the cable car support 12. The area where maintenance or repair work is to be carried out can be entered into the control unit 4 via a line 51 or via radio. A transmitter 6 is also provided, which is operated by the control unit 4 via a line 41.
[0013] As this is further explained in FIG.3As shown, the cable car vehicle 15 has a receiver 6a and the chassis 15a of the cable car vehicle 15 has a warning light 7 and / or an acoustic warning device 7a, which are activated by the control unit 4 via the transmitter 6 and the receiver 6a.
[0014] As soon as maintenance or repair work is carried out on a cable car support 12, a signal is sent by the input device 5 via line 51 to the control unit 4, which identifies the respective cable car support 12. Using the measurement data that is sent by the measuring devices 3 via lines 31 to the control unit 4, a signal is then transmitted to the cable car 15 via the transmitter 6 and the receiver 6a when a cable car 15 approaches this cable car support 12. This signal triggers the warning light 7 and / or the acoustic warning device 7a. This alerts the operating personnel on this cable car support 12 that a cable car 15 is approaching. In addition, a control signal is sent from the control unit 4 via line 42 to the drive for the haul rope 14, which significantly reduces the speed of the haul rope 14.As soon as the cable car vehicle 15 has passed the cable car support 12, the speed of the haul rope 14 is brought back to the operating speed.
[0015] Similarly, when the cable car 15 approaches the cable car support 12, the control unit 4 can switch off the drive for the haul rope 14. As soon as the operating personnel are secured, the drive for the haul rope 14 is switched on again, the cable car 15 is moved past the cable car support 12 and the operating speed is resumed.
[0016] This operating procedure, or rather this cable car system, ensures optimal protection of the operating personnel during maintenance and repair work.
