Track vibration reduction fastener
The embodiment of the invention relates to a rail vibration reduction fastener which comprises an iron base plate, a height adjusting base plate, an elastic base plate and a fastener, and the height adjusting base plate is arranged below the iron base plate; the elastic base plates are arranged between the iron base plate and the height adjusting base plate and comprise the first elastic base plate and the second elastic base plate, the upper surface of the first elastic base plate makes contact with the lower surface of the iron base plate, and the lower surface of the second elastic base plate makes contact with the upper surface of the height adjusting base plate. The rigidity of the first elastic base plate is smaller than that of the second elastic base plate; the fastener sequentially penetrates through the iron base plate, the elastic base plate and the height adjusting base plate so as to fasten the iron base plate, the elastic base plate and the height adjusting base plate together. According to the embodiment of the invention, to a certain extent, corrugation diseases such as deflection and eversion of the steel rail can be avoided, the stability of the steel rail is guaranteed, a smooth operation condition is provided for a train to pass through a switch, impact vibration of a wheel rail is relieved, the vibration and noise reduction effects are further achieved, and in addition, the maintenance cost is also reduced.
本发明实施例是关于一种轨道减振扣件，包括：铁垫板、调高垫板、弹性垫板以及紧固件，其中，调高垫板设置于铁垫板的下方；弹性垫板设置于铁垫板以及调高垫板之间，弹性垫板包括第一弹性垫板和第二弹性垫板，第一弹性垫板的上表面与铁垫板的下表面相接触，第二弹性垫板的下表面与调高垫板的上表面相接触，且第一弹性垫板的刚度小于第二弹性垫板的刚度；紧固件依次穿设于铁垫板、弹性垫板以及调高垫板，以将三者紧固在一起。本发明实施例在一定程度上，可以避免引起钢轨偏转、外翻等波磨病害，保障了钢轨的稳定性，为列车过岔提供了平顺的运行条件，缓解了轮轨冲击振动，进一步起到减振降噪作用，此外，也减低了维护成本。
