Transverse limiting type vibration reduction fastener system and mounting method thereof
The invention discloses a transverse limiting type vibration reduction fastener system and an installation method thereof.The fastener system comprises a sleeper and a pre-buried sleeve arranged in the sleeper, and an insulating buffer base plate is laid on the sleeper; a shock absorber assembly formed by connecting an upper iron base plate, a middle shock absorption base plate, a lower iron base plate and a limiting block into a whole through a connecting sleeve is laid on the insulating buffer base plate, a distance adjusting fastener is placed on the shock absorber assembly, and an anchor bolt penetrates through a spring washer, a distance adjusting buckle plate, the shock absorber assembly and the insulating buffer base plate to be connected with an embedded sleeve. An under-rail backing plate is laid on the upper iron backing plate, a steel rail is laid on the under-rail backing plate, insulating gauge blocks are installed on the two sides of the steel rail, and the steel rail is buckled on the upper iron backing plate through elastic strips. The vibration reduction fastener is low in vertical rigidity and high in transverse rigidity, vibration and noise of a steel rail can be effectively reduced, installation and maintenance of the fastener can be facilitated, and meanwhile the transverse stability of a fastener system is guaranteed.
本发明公开了一种横向限位式减振扣件系统及其安装方法，扣件系统包括轨枕和在轨枕内设置的预埋套管，在轨枕上铺设绝缘缓冲垫板，在绝缘缓冲垫板上铺设由上铁垫板、中间减振垫板、下铁垫板和限位块通过连接套连接为一体形成的减振器组件，在减振器组件上安放调距扣件，锚固螺栓穿过弹簧垫圈、调距扣板、减振器组件和绝缘缓冲垫板与预埋套管连接，在上铁垫板上铺设轨下垫板，在轨下垫板上铺设钢轨，在钢轨两侧安装绝缘轨距块，通过弹条将钢轨扣压在上铁垫板上。本发明提供了一种低垂向刚度、高横向刚度的减振扣件，既能有效减少钢轨振动和噪声，又能方便扣件的安装与维护，同时还保证了扣件系统的横向稳定性。
