Vibration reduction fastener
The invention relates to a vibration reduction fastener of a steel rail, the vibration reduction fastener comprises an upper iron base plate, a lower iron base plate and an anchor bolt, a socket structure capable of elastically supporting the upper iron base plate to enable the upper iron base plate to float on the lower iron base plate is arranged between the upper iron base plate and the lower iron base plate, and the socket structure comprises a pair of socket grooves and a socket table; the socket platform is matched with the socket groove in a socket mode, an elastic body which is arranged between the socket platform and the socket groove and at least covers the circumferential surface of the socket platform is arranged on the socket platform in a sleeving mode, and the matching surface of the socket platform and the elastic body and the matching surface of the socket groove and the elastic body are each provided with at least one pair of inclined surfaces which are oppositely arranged and support stress to be inclined upwards. The pre-tightening structure is used for adjusting the distance between the upper iron base plate and the lower iron base plate to change the pre-pressing force on the elastic body; the elastic body in the fastener is not bonded with the iron base plate, so that the elastic body can be replaced, and the rigidity of the elastic body can be adjusted through the pre-tightening structure.
本发明涉及钢轨的减振扣件，该减振扣件包括上铁垫板和下铁垫板以及将锚固螺栓，在上铁垫板和下铁垫板之间设置有能够对上铁垫板实现弹性支撑使上铁垫板浮置于下铁垫板之上的承插结构，该承插结构包括一对承插槽和承插台，承插台与承插槽承插配合且在承插台上套设有置于承插台和承插槽之间至少覆盖承插台周向表面的弹性体，所述的承插台与弹性体配合面以及承插槽与弹性体配合面均至少有一对相对设置且支撑受力斜向上的倾斜面；还包括有用于调节上铁垫板和下铁垫板之间间距改变对弹性体预压紧力的预紧结构；该扣件中的弹性体不与铁垫板粘接，从而能够实现对弹性体的更换，通过预紧结构还能够调节弹性体刚性。
