Magnetic levitation traffic track system

Abstract

The invention discloses a magnetic levitation traffic track system. The system comprises abutments, magnetic tracks, an aluminum induction plate and a channel beam, wherein the channel beam is connected with the abutments through supports and strides over the two abutments, the channel beam is formed by connecting a plurality of cross beams formed through horizontal in-place casting of reinforcingsteel bars reserved at the end parts of U-shaped beam lower wings of two U-shaped beam units, the magnetic tracks are mounted at the bottoms of U-shaped beam upper wings, the aluminum induction plateis arranged in the magnetic tracks, and power supply tracks are mounted on the U-shaped beam lower wings and correspond to the magnetic tracks above the power supply tracks. The system has the benefits as follows: the system adopts a levitation-traction-guide integrated overall structure and is high in structure rigidity and good in operation stability; the traction levitation gap is smaller thanbefore, and therefore, the linear motor efficiency is higher, and energy consumption is lower; a levitation system, a traction system and a guide system are all arranged in the channel beam, and in the train running process, the channel beam has a good sound insulation effect and can isolate the magnetic field of the system and reduce magnetic radiation.

Description

technical field [0001] The invention relates to a magnetic levitation traffic rail system, which belongs to the technical field of rail traffic. Background technique [0002] The maglev transportation system has comprehensive advantages such as small turning radius, low operating noise, strong climbing ability, low operation and maintenance costs, safety and reliability, and has become an important development form of modern urban rail transit. The maglev transportation system realizes the interaction between the train and the track through electromagnetic force, and realizes the non-contact suspension, guidance and traction of the vehicle. Therefore, the technical performance of the track system directly affects the operation quality of the maglev train. [0003] The existing maglev transportation track system is mainly composed of piers, track beams, power supply rails, supports, sleepers, F rails, aluminum induction plates and signal cables. On the track beam, the F rail...

AI Technical Summary

Problems solved by technology

The F rail and the aluminum induction plate are in a cantilever state, which is greatly affected by the deformation of the vehicle load, which is not conducive to controlling the suspension air gap between the vehicle suspension frame and the guide rail; in addition, the F rail, power supply rail, aluminum induction plate and auxiliary equipment beside the track are all exposed Installed outside the track beam, the noise is loud when the train is running
