Self-anchored gravity-pressurized repeatedly-reinforced rail transit rail fixing support

Abstract

The invention discloses a self-anchored gravity-pressurized repeatedly-reinforced rail transit rail fixing support, which comprises sleepers, positioning bolts, a rail body, pressing plates and air bags, wherein a positioning sleeve is mounted at the top of the sleeper in an embedded manner; a positioning base is arranged above the edge of the sleeper; a reinforcing rib is connected between positioning blocks through a rotating shaft; the ends of the reinforcing rib are provided with limiting strips in a hinged mode; the lower ends of the positioning bolts penetrate through the positioning base and are arranged in the positioning sleeves; the upper ends of the positioning bolts are fixedly connected with limiting nuts; the rail body is arranged in the center of the top of the positioning base; and one ends of fixing pieces are fixed to the outer walls of the two sides of the middle of the rail body through bolts. According to the self-anchored gravity-pressurized repeatedly-reinforcedrail transit rail fixing support, the adverse effect of vibration on the reinforcing stability when a rail is used is reduced, continuous support reinforcing can be conducted when a train runs, the reinforcing convenience is improved, and loosening and falling of a reinforcing structure are avoided.

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.
