Description

Continuous opening and closing operation method for bearing cable of multi-cable car

Technical Field

The invention relates to a continuous opening and closing operation method for a bearing cable of a multi-cable car.

Background

The progress of the cableway technology makes the passenger cableway become a mainstream sightseeing vehicle. In some cities, such as bolivia initialla, london, uk, cableways are also used as urban vehicles, and since the cableways run in the air, the ground vehicle driving is not affected, the cableways have strong terrain adaptability and free arrangement, the circularly suspended cableways have quite mature technology and keep a safe operation state all the time. However, the running speed and the bearing capacity are bottlenecks which hinder the development of the passenger transport cableways, so that the passenger flow of the passenger transport cableways is always at a lower level and cannot bear the transportation tasks above the medium transport volume, and long queuing waiting time is required for riding most cableway systems.

The prior passenger ropeway field is more advanced 3S ropeway, namely a three-line circulation unhooking type ropeway consisting of two bearing running ropes and one traction rope. The cableway combines the bearing technology of a reciprocating type cableway and the traction technology of a hanging type cableway, and has the characteristics of large span, strong lifting capacity, large carriage space and quick running. At present, 13 ropeways of the type are available in the world, are firstly applied to Lushan passenger transport ropeways in China and are produced and provided by Dobema corporation of Switzerland, and have better operation effect.

Although the 3S cableway has great advantages of transportation capacity and speed, the bracket in the interval needs to be supported by riding wheels or brackets due to the mode that the walking wheels and the bearing ropes advance in a rolling mode, when a cable car passes through the bracket at high speed, the walking wheels cannot completely contact the bearing ropes, and accidents are easily caused by rope separation (rope separation) when the cables swing transversely. The speed of the 3S cableway is generally set to within 10m/S for safety reasons.

Secondly, because the upper part of the cable needs to be in contact with the running wheels, structural conflict can be caused if a suspension type bearing structure is arranged, the bearing capacity of the cable between the two supports is limited due to the reason, and the distance between the two supports cannot be set too large under the condition that the distance between the two supports is not large, so that the transport capacity of the cableway is influenced.

At present, the running speed of the main stream passenger ropeway does not exceed 15m/s, and the main reason of speed limitation is the safety problem of the ropeway. The fastest cable car line in the world mostly adopts the operation mode of a multi-cable cableway, in an operation module positioned at the top of a carriage, a rope clip positioned below and a traction cable are connected in a clasping way to pull the cable car to advance, a plurality of walking wheels positioned at the upper part and used for bearing are contacted with one or more bearing cables and roll to walk, and if the operation speed is too high, the walking wheels can be disconnected (rope falling) in the middle section of a passing section to cause serious accidents. The large-span support erected according to the prior art is also very limited in bearing capacity, the contact surface between the walking wheels and the walking cables is too small, the section size of the walking cables is generally not large, and if the speed of the middle section in the running region is too high, local stress between the walking wheels and the bearing cables is possibly too large, so that the rope is broken. The optimal solution of solving the problem of wire separation and improving the operation safety is that the upper part of the bearing cable is kept to be free and the travelling wheels can be completely attached to the bearing cable in the whole operation process, so that the operation speed of the cable car is improved. According to the prior art, this situation results in the inability to arrange support structures around the mid-span cables in the runlength. The long-distance use of the layout results in low bearing capacity between the zones, and the transportation capacity cannot be substantially improved.
