Track base plate with shock absorption and noise reduction functions

Abstract

The invention discloses a track base plate with shock absorption and noise reduction functions. The base plate comprises an pre-embedded base plate and a protection mechanism. A fixed base is arrangedat the top end of the pre-embedded base plate; the track base plate is arranged at the bottom end of the inner side of the fixed base; the protection mechanism comprises holes; the number of the holes is two in total; and the two holes are aranged in the two sides of the surface of the top end of the track base plate correspondingly, protective inner ring sleeves are arranged on the inner sides of the holes, limiting fixing grooves are formed in the surfaces of the inner sides of the holes, limiting fixing blocks are fixedly connected to the surfaces of the outer sides of the protective innerring sleeves, and the limiting fixing blocks are clamped to the inner sides of the limiting fixing grooves. Compared with the prior art, the track base plate has the beneficial effects that a rubbercushion plate is designed to achieve a damping effect, round protruding blocks are additionally arranged at the top end of the rubber cushion plate, gaps are reserved, a buffering effect is achieved,the protective inner ring sleeve is additionally arranged on the inner side of the hole, and phenomena that after a pressing plate fixing bolt penetrates through the inner side of the hole, the innerside of the hole is abraded, deformed and cracked are prevented.

Description

technical field [0001] The invention belongs to the technical field of rail transportation, and in particular relates to a rail backing plate with the function of shock absorption and noise reduction. Background technique [0002] Railway is a track line for trains and other means of transportation. Railway transportation is a land transportation method that uses locomotives to pull train vehicles on two parallel rails. The traditional way is to travel on steel wheels, but in a broad sense, railway transportation still includes non-steel wheel travel methods such as maglev trains, cable cars, and cableways, or rail transportation. The rails provide an extremely smooth and hard medium on which the train wheels roll with minimal friction, making it more comfortable for people on it, and it saves energy. If properly configured, rail transport can save 50 to 70 percent of energy compared to road transport for the same weight. Moreover, the rails can evenly disperse the weight ...

AI Technical Summary

Problems solved by technology

Track backing plate is an important part of the railway track structure, installed between the steel rail and the concrete sleeper, its main function is to buffer the high-speed vibration and impact produced by the vehicle passing the rail, protect the roadbed and sleeper, and electrically conduct the signal system Insulation, but the current backing plate is easy to age, deformation and cracking are easy to occur at the opening, and the shock absorption and corrosion resistance are poor, so it cannot be used for a long time. After a period of use, it needs to be disassembled and replaced, which is a great waste of resources. The backing plate is not easy to install, which increases the workload of the staff, so we propose a track backing plate with the function of shock absorption and noise reduction
