Sleeper damping device
The invention discloses a sleeper damping device, and relates to a railroad sleeper. A sleeper reserved hole is formed in the lower portion of the sleeper, a shock pad is arranged below the sleeper, a shock pad reserved hole is formed below the shock pad, the sleeper reserved hole corresponds to the shock pad reserved hole in position, an insert is arranged in the sleeper reserved hole, a pin penetrates through the shock pad reserved hole to drive the shock pad, and the pin penetrates through the insert to be matched with the insert. Therefore, the shock pad can be tightly attached to the sleeper; the upper surface of the shock pad is a plane, the lower surface of the shock pad is provided with a plurality of regularly-distributed protrusions, tie bars are additionally arranged between the adjacent protrusions, the tie bars are of a structure shaped like a Chinese character'mi ', and the height of the tie bars is 1/6-6/6 of that of the protrusions. The shock pad has the advantages that the pin buckle principle is adopted, the shock pad and the sleeper are conveniently combined, cost is low, and labor and time are saved. The lacing wire structure is additionally arranged between the hemispheres below the shock pad, and the adjacent hemispheres are connected, so that vibration is dispersed, and the vibration is effectively reduced. Therefore, noise is reduced, and the service life of the sleeper (cement sleeper) is prolonged.
一种轨枕减震装置，涉及铁路轨枕；轨枕下方设置有轨枕预留孔，在轨枕下方设置有减震垫，减震垫下方设置有减震垫预留孔，轨枕预留孔与减震垫预留孔位置对应，轨枕预留孔内置嵌件，销件穿过减震垫预留孔连带起减震垫，销件穿入嵌件后与配合，从而能够使减震垫紧贴轨枕；所述减震垫上面为平面，下面为众多规则分布的凸起物，相邻凸起物间加有拉筋，拉筋呈米字结构，拉筋的高度为凸起物高度的1/6—6/6。本发明的有益效果是：采用销扣原理，使减震垫与轨枕方便结合，成本低，省工，省时。采用减震垫下面半球间加有拉筋结构，将相邻的半球相连接，使震动得以分散，有效地减少了震动。从而减少了噪音，延长了轨枕（水泥枕）的使用寿命。
