Problems solved by technology

[0003] 1. The vibration mass is small and cannot effectively absorb the high-frequency vibration energy of the rail, which will cause abnormal wavy wear due to wheel-rail resonance, and the vibration and noise reduction performance is poor
[0004] 2. The on-site assembly accuracy is poor, the effect is poor, wasting precious track laying time, and the compression deformation is used, and problems will occur during operation

Abstract

The invention relates to a shearing type elastic sleeper compound shock absorber for shock absorption of a steel rail. The compound shock absorber comprises a concrete sleeper (1), a rubber shock absorber (2) and an integral ballast bed (3) of cast-in-place concrete of the rail. The concrete sleeper (1) is in an elliptical table shape. A ring of groove (101) is arranged at the outer edge on the top end surface of the concrete sleeper (1) and the middle section of the concrete sleeper (1) is inwardly sunk, thereby forming a ring of sunk area (102). The rubber shock absorber (2) is in a gumshoe shape, the bottom (201) of the gumshoe is elliptical and the ring (202) of the gumshoe is in an elliptical ring shape. A plurality of small cone-shaped tables (203) is arranged on the top end surface of the bottom (201) convexly. A ring of flange (204) is arranged in the middle section of the inner ring of the ring (202) and a plurality of vertical grooves (205) is arranged uniformly on the flange (204). The rubber shock absorber (2) is embedded into the integral ballast bed (3) of cast-in-place concrete of the rail and the concrete sleeper (1) is embedded into the gumshoe-shaped rubber shock absorber (2). The invention can effectively absorbs the higher-mode vibration energy of the steel rail, so as to shorten the construction period of the shearing type elastic sleeper compound shock absorber.

Description

(1) Technical field [0001] The invention relates to a sleeper shock absorber. For shock absorption of rails. It belongs to the technical field of rail transit accessories. (2) Background technology [0002] Before the present invention is made, generally adopt simple metal / rubber shock absorber to realize the damping of steel rail in the past. This damping mode mainly has the following deficiencies: [0003] 1. The vibration mass is small and cannot effectively absorb the high-frequency vibration energy of the rail. It will cause abnormal wave-shaped wear due to wheel-rail resonance, and the vibration and noise reduction performance is poor. [0004] 2. On-site assembly has poor accuracy and poor effect, wasting valuable track laying time, and uses compression deformation, which will cause problems during operation. (3) Contents of the invention [0005] The object of the present invention is to overcome the above disadvantages and provide a shear type elastic sleeper ...
