A discrete column type track bridge system for maintenance in the maglev train depot

Abstract

The invention discloses a discrete type column type rail bridge system for the intra-garage overhaul of a maglev train. The rail bridge system comprises multiple rail bridge units of the same structure. The rail bridge units are arranged at intervals in the running direction of the maglev train and the interval distance s is larger than or equal to 0.5 m and smaller than or equal to 1.4 m. Each single rail bridge unit comprises a steel rail sleeper, two F-type steel rails and two supporting columns. The steel rail sleepers are horizontally arranged and are perpendicular to the running direction of the maglev train. Every two F-type steel rails are arranged at the two ends of the top of the corresponding steel rail sleeper. Every two supporting columns are arranged at the two ends of the bottom of the corresponding steel rail sleeper and provided with rail bearing tables connected with the bottom of the corresponding steel rail sleeper through fastener units. The height H of each supporting column is larger than or equal to 1.1 m and smaller than or equal to 1.3 m and the interval between every two adjacent supporting columns is larger than or equal to 0.5 m and smaller than or equal to 1.4 m. By the adoption of the discrete type column type rail bridge system, an overhaul person can penetrate the rail bridge system conveniently, and the problem that an existing rail is not suitable for the intra-garage overhaul of the maglev train is solved.

Description

technical field [0001] The invention belongs to the field of maintenance of maglev trains, and more particularly relates to a discrete column type track bridge system for maintenance in a maglev train depot. Background technique [0002] With the development of modern science and technology, as a high-speed, comfortable, safe, energy-saving and environmentally friendly maglev train has become an ideal means of transportation for people in the 21st century. As a new type of rail transportation, medium and low-speed maglev trains use electromagnetic attraction or electric repulsion to suspend the train above the track, and the train is driven by a linear motor. There are no wheels and corresponding transmission systems, and there is no ground contact with the ground. There is no friction loss, the operation and maintenance are simple and convenient, and it has a good development prospect. [0003] The core of the levitation electromagnet of the medium and low-speed maglev tra...

Problems solved by technology

[0004] However, when the maglev train breaks down, it needs to be moved to the warehouse for maintenance. During the maintenance operation, the operators need to walk along the line under the vehicle or traverse from the bottom to the side to carry out comprehensive maintenance operations. When the track beam in the form of ordinary continuous beams is used to support the maglev train, there is no space to walk under the car, and there is no horizontal passageway.

Therefore, the ordinary continuous beam track beam in the prior art is not suitable for the maintenance of the maglev train in the warehouse, and it is necessary to study and design a kind of track bridge suitable for the maintenance of the maglev train in the warehouse.
