Abstract

The invention discloses a magnetic levitation track structure which comprises a concrete body and a steel structure assembly. The steel structure assembly comprises an upper-layer steel plate, a lower-layer steel plate, a connecting plate and a U-shaped steel rail; the steel structure assembly is designed in a modularized and universal mode, compared with a prefabricated slab track beam, the steel structure assembly is very convenient to install and adjust, the manufacturing process is very simple, and the manufacturing and installing cost is saved; when a certain section of track breaks down, rapid maintenance and replacement can be achieved; the U-shaped steel rails are adopted, the rail cost is greatly reduced, the assembling difficulty is reduced, the maintainability and the integrity are improved, the magnetic levitation rail structure is jointly composed of the concrete body and the steel structure assembly, the steel structure assembly is made of a large number of sectional materials and plates, and the economical efficiency is greatly improved; meanwhile, the stability and the safety of the track structure are not reduced.

Description

technical field [0001] The invention relates to the field of maglev tracks, in particular to a maglev track structure. Background technique [0002] The difference between the maglev transportation system and the general railway is that the train is suspended by magnetic force, and there is no direct contact between the train and the track. Compared with the traditional railway transportation, the limitation of the adhesion force between the wheel and rail systems is eliminated. Therefore, the maglev system is an energy-saving and environmentally friendly mode of transportation. [0003] The problems existing in the existing magnetic levitation track structure are: 1. The F-shaped rail is difficult to manufacture, and the processing precision is extremely high, which makes the assembly of the maglev track difficult; 2. The F-shaped rail is installed in the form of a cantilever beam, which bears the bending moment The operation affects the accuracy of the F-shaped rail; 3. T...
