Multifunctional lift type suspension rail transportation system and braking, lifting, stabilizing and turnout device thereof

Abstract

The invention discloses a multifunctional lift type suspension rail transportation system which is composed of overhead struts, truss tubular girders, a rail, a steering frame, a lifting and stabilizing system, a vehicle, turnouts, station facilities and automatic control and other mating systems, wherein the design of the multifunctional truss tubular girders can selectively realize functions of water pipes, pedestrian passageways, greenery landscapes, solar power generation and common pipelines on the basis of lightening dead-weight and saving materials to the maximum extent. The vehicle runs under the steering frame in a suspending mode, and the steering frame is composed of a phi-shaped plate rail, a U-shaped steering bracket with an upward opening and a permanent magnet brake device. As a magnetic suction caterpillar instead of a traveling wheel pair is used for driving a brake device, climbing ability can be improved greatly. A monolithic movement turnout is used for steering. When an overhead station is not selected, a lifting system and a self-compression foldable frame type anti-shaking and anti-falling device are selected, so that big marshalling operation and seamless linkage of multiple modes of transportation can be realized. The multifunctional lift type suspension rail transportation system is applicable for the field of urban or inter-city rail transportation, and has multiple technical specifications from low traffic volume to high traffic volume.

Description

technical field [0001] The invention relates to a rail transit system and a braking, lifting, stabilizing and turnout device used in the system. The track of the system is located on the elevated truss pipe beam, and the vehicle is suspended to walk under the track, which can be lifted and lowered, and can also perform various operations. The function is extended, and it can even be seamlessly linked with other modes of transportation. It is a kind of rail transit in the public transportation system. Background technique [0002] The ground public transportation system has the natural defects of small traffic volume, heavy pollution, large road occupation and insufficient ground road space. The subway has a large transportation capacity, no pollution, and does not occupy ground road space. However, it faces limitations such as limited underground space, high subway construction cost, insufficient economy, and geological conditions. Suspended rail transit can effectively us...

Problems solved by technology

But so far through many years of development, the existing suspension rail transit system still has some deficiencies, mainly in: (1) the track is a bottom-opening integral box beam structure, which is integrally welded and formed. Although it can block rain and snow, the bottom opening As a result, the rigidity of the overall structure is insufficient, which can only be overcome by increasing the amount of steel used, resulting in a substantial increase in cost; at the same time, the construction is very difficult, the welding process requires high requirements, and the overall deformation control is difficult, which greatly increases the cost of the construction process ; In addition, although the overall lower opening box beam track structure is known as maintenance-free for life, the track, bogie, power transmission line, communication line, etc. are all enclosed in the track beam, and maintenance of lines and equipment during use is essential. This structure makes maintenance very inconvenient and increases maintenance costs; moreover, this structure is not convenient for partial replacement, nor is it convenient for expansion of function and capacity; finally, the overall lower opening box girder The structure gives the feeling that it is not very beautiful, and it is not very harmonious with the surrounding environment; (2) using rubber tires for driving and braking, the driving and braking force is insufficient, and it is necessary to do a friction-increasing coating on the surface of the track to increase friction. As a result, the wear of the tires has increased significantly, and the dust pollution of the environment has been correspondingly increased.

At the same time, it also leads to insufficient climbing ability and poor terrain adaptability; (3) expensive elevated stations need to be erected, and the cost increases; (4) it is inconvenient to transfer and is not compatible with other existing transportation systems; (5) traffic volume Insufficient, unable to meet the needs of mass traffic
