A vibration reduction and safety protection device for track crossing

technical field

The invention relates to the technical field of safety protection at rail crossings, in particular to a vibration reduction and safety protection device for rail crossings.

Background technique

Since the development of railway transportation, the contact motion of wheels and tracks has been accompanied by the generation of impact energy, especially at track intersections, causing vibration and noise and traffic accidents caused by track intersections. The resulting vibration and noise not only cause environmental damage Pollution has brought great noise pollution to people's lives, and there are potential safety hazards. There is no effective method for traditional safety protection at track crossings. The traditional method of reducing vibration and noise is to place rubber pads under the sleeper, or to absorb vibration energy through damping materials alone. However, the effects of rubber pads and damping materials The effect of vibration reduction and noise reduction is not good, and it cannot fundamentally achieve the effect of vibration reduction and noise reduction, and the life of the rubber pad is relatively short, so it is more troublesome to replace.
