A self-anchored rail rail fixed support for repeated reinforcement by gravity and pressure

Abstract

The invention discloses a self-anchoring type gravity pressurized and repeatedly reinforced rail transit rail fixed support, which comprises a sleeper, a positioning bolt, a track body, a pressure plate and an air bag. The top of the sleeper is embedded with a positioning sleeve, and the sleeper A positioning seat is arranged above the edge, and reinforcing ribs are connected to the rotating shaft between the positioning blocks, and the ends of the reinforcing ribs are hingedly installed with a limit strip. The lower end of the positioning bolt penetrates the positioning seat and is arranged inside the positioning sleeve. The upper end of the bolt is fixedly connected with the limit nut, and the track body is arranged at the top center of the positioning seat, and one end of the fixing piece is fixed with bolts on the outer walls of both sides of the middle part of the track body. The self-anchored gravity-pressurized and repeatedly reinforced rail rail fixed support reduces the adverse effect of vibration on the reinforcement stability when the track is in use, and can carry out continuous support reinforcement when the train is running, improving the convenience of reinforcement. , will not cause loosening and falling of the reinforced structure.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a rail transit rail fixed support of self-anchor type gravity pressure and repeated reinforcement. Background technique [0002] The construction of modern rail transit provides the cornerstone of rapid communication for the development of science and technology and logistics transportation. The construction of rail transit requires the installation of auxiliary positioning traffic tracks to provide accurate guiding roads for the transportation and movement of vehicles. Installation and positioning, improve the positioning stability of the rail track, and prevent it from loosening due to vibration and external force factors during long-term use. It is necessary to install auxiliary clamping and reinforcement structures at the junction of the rail track and the sleeper to maintain the stability of the track. And working effect, carry out the stable guide transportation of the...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a self-anchored rail transit rail fixed support repeatedly reinforced by gravity to solve the above-mentioned background technology. Support reinforcement, the setting of its positioning method will cause loose and unstable positioning of the track under the vibration of the track when it is used, and there are defects in use, and it will cause large deformation of the fixed support by external force, and the reinforcement method is cumbersome , cannot make full and effective use of the kinetic energy of rail transportation vehicles. After long-term use, artificial support reinforcement is required, which is prone to reinforcement omissions, leading to serious safety hazards in the use of rails.
