Problems solved by technology

[0002] While the under-rail vibration isolation measures are becoming more and more mature, the vibration transmitted from the track to the ground foundation can be greatly reduced, but the rail vibration and radiated noise caused by track irregularities have not been substantially improved.
The low-rigidity under-rail backing plate increases the distance that the rail vibration propagates along the rail, so the noise generated by the rail will increase; while the use of a higher-rigidity under-rail backing plate can reduce the noise of the rail, but it will also increase the noise of the sleeper. noise

Embodiment Construction

[0011] A shock-absorbing rail is composed of a rail surface, a rail side, a rail waist and a rail bottom, and a shock-absorbing mechanism is arranged at the rail bottom and the rail bottom.

[0012] The damping mechanism is an integral damping block 2 wrapped around the waist of the rail and the bottom of the rail to reduce the mutual friction vibration caused by many parts.

[0013] There is a deformation gap 3 between the shock absorber and the two sides of the rail waist, which can ensure that the rail has a certain expansion space and leave a movement gap.

[0014] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and cannot be considered as limiting the implementation scope of the present invention. All equal changes and improvements made according to the creative scope of the present invention should still belong to the scope covered by this patent.

Abstract

The invention provides a vibration reduction steel rail which is composed of a steel rail face, a steel rail side face, a steel rail waist part and a steel rail bottom. A vibration reduction mechanism is arranged at the steel rail bottom and the steel rail waist part. The vibration reduction mechanism of the steel rail can improve the attenuation rate of vibration along the steel rail without increasing the noise of sleepers, and the obvious noise reduction effect can be achieved.

Description

technical field [0001] The invention relates to a steel rail, especially a steel rail with shock-absorbing effect. Background technique [0002] While the under-rail vibration isolation measures are becoming more and more mature, the vibration transmitted from the track to the ground foundation can be greatly reduced, but the rail vibration and radiated noise caused by track irregularities have not been substantially improved. The low-rigidity under-rail backing plate increases the distance that the rail vibration propagates along the rail, so the noise generated by the rail will increase; while the use of a higher-rigidity under-rail backing plate can reduce the noise of the rail, but it will also increase the noise of the sleeper. noise. If a rail vibration absorber is added to the rail supported by the cushion plate, the attenuation rate of vibration along the rail can be increased without increasing the noise level of the sleeper, and an obvious noise reduction effect c...
