Rail transit damping mechanism
The invention belongs to the technical field of rail transit, and particularly relates to a rail transit damping mechanism. Comprising a sleeper rail and a steel rail, the sleeper rail is sequentially provided with an insulating buffer cushion plate, an iron cushion plate lower heightening cushion plate, an iron cushion plate, an under-rail heightening cushion plate and an under-rail cushion plate from bottom to top, the top of the under-rail cushion plate is attached to the bottom of the steel rail, and two anchor bolts are symmetrically connected to the two sides of the sleeper rail in a threaded mode; the top end of the anchor bolt extends to the position above the iron base plate. Vibration energy on the steel rail can be evenly dispersed through the buffering blocks evenly distributed on the under-rail base plate, the vibration energy is converted into heat energy generated by friction between the damping blocks and the wedge-shaped blocks, the effect of reducing vibration is further achieved, the pressure of vibration on the under-rail base plate is relieved, and the service life of the steel rail is prolonged. Through the structure, the damping system of the under-rail backing plate is enriched, the damping effect is improved, rapid aging of the under-rail backing plate is avoided, and the service life of the under-rail backing plate is prolonged.
本发明属于轨道交通技术领域，具体的说是一种轨道交通减震机构；包括枕轨和钢轨，所述枕轨上从下到上依次设有绝缘缓冲垫板、铁垫板下调高垫板、铁垫板、轨下调高垫板和轨下垫板，所述轨下垫板的顶部与钢轨的底部相贴合，所述枕轨的两侧对称螺纹连接有两个锚固螺栓，所述锚固螺栓的顶端延伸至铁垫板的上方；本发明通过轨下垫板上均匀分布的缓冲块能够均匀分散钢轨上的震动能量，通过将震动的能量转化为减震块与楔形块之间摩擦产生的热能，进一步实现了减小震动的效果，减轻了轨下垫板受到震动的压力，通过此结构丰富了轨下垫板的减震体系，提高了减震效果，避免了轨下垫板的快速老化，延长了其使用寿命。
