Locking type compression vibration reduction fastener and mounting method thereof
The invention discloses a locking type compression vibration reduction fastener and a mounting method thereof, the vibration reduction fastener comprises a sleeper and a plastic sleeve pre-buried in the sleeper, and an anchor bolt penetrates through a distance adjusting pinch plate, a lower iron base plate and an insulating buffer base plate to be connected with the plastic sleeve; a middle vibration reduction base plate and an upper iron base plate are sequentially arranged on the lower iron base plate, and the lower iron base plate, the middle vibration reduction base plate and the upper iron base plate are connected into a whole through connecting sleeves; the steel rail is limited and buckled on the upper iron backing plate through the under-rail backing plate, the insulating gauge block, the T-shaped bolt, the nut and the elastic strip. The vibration reduction fastener is low in vertical rigidity and high in transverse rigidity, the fastener has the low installation height, and the bottom plate anchor bolt can be universal with a line common fastener. Vibration and noise of the steel rail can be effectively reduced, meanwhile, the upper iron base plate, the middle damping base plate and the lower iron base plate are self-locked into a whole, the pulling resistance of the fastener can be increased, the transverse stability is good, and installation and maintenance of the fastener are facilitated.
本发明公开了一种锁紧式压缩型减振扣件及其安装方法，减振扣件包括轨枕和轨枕中预埋的塑料套管，锚固螺栓穿过调距扣板、下铁垫板和绝缘缓冲垫板与塑料套管连接；下铁垫板上依次设置中间减振垫板和上铁垫板，通过连接套将下铁垫板、中间减振垫板、上铁垫板连接为一个整体；钢轨通过轨下垫板、绝缘轨距块、T型螺栓、螺母和弹条被限位扣压在上铁垫板上。本发明提供了一种低垂向刚度、较高横向刚度的减振扣件，扣件拥有较低的安装高度，底板锚固螺栓可与线路普通扣件实现通用。本发明能有效减少钢轨振动和噪声，同时通过将上铁垫板、中间减振垫板、下铁垫板自锁为一体的形式可使扣件抗拔力增加、横向稳定性良好，方便扣件的安装、维护。
