Higher vibration reduction fastener of urban rail transit rail
A higher vibration reduction fastener of an urban rail transit rail comprises an under-rail pad, an upper iron base plate, a middle vibration reduction pad, a vibration isolation plate, an under-plate vibration reduction pad, a lower iron base plate, an insulation coupling base plate and a fixing device. The under-rail pad, the upper iron backing plate, the middle anti-vibration pad, the vibration isolation plate, the under-plate anti-vibration pad, the lower iron backing plate and the insulation coupling backing plate are arranged layer by layer from top to bottom; the fastener has the beneficial effects that the lower iron base plate of the fastener is of an integrated structure, so that the transverse stability of the fastener is improved; three layers of elastic base plates are adopted, so that the fastener achieves a better damping effect; by adjusting a nut of the pre-tightening bolt system, the assembling efficiency of the fastener is greatly improved, and on-site installation and maintenance are very convenient; and by arranging a drainage structure, it can be guaranteed that components in the device cannot be eroded or damaged, meanwhile, the friction effect between the components of the device is improved, and the use reliability of the device is guaranteed.
一种城市轨道交通轨道高等减振扣件，包括轨下垫、上铁垫板、中减振垫、隔振板、板下减振垫、下铁垫板、绝缘耦合垫板和固定装置；所述的轨下垫、上铁垫板、中减振垫、隔振板、板下减振垫、下铁垫板和绝缘耦合垫板自上而下逐层设置；本发明的有益效果在于：本装置的下铁垫板采用一体式结构，从而提升了扣件的横向稳定性；采用三层弹性垫板，使扣件达到更好的减振效果；采用调整预紧螺栓系统螺母极大提高了扣件的组装效率并且非常方便现场的安装维护；通过设置排水结构，这样不仅能够保证装置内部的部件不会发生侵蚀的损害，同时也增加了装置各个部件之间的摩擦效果，保证的装置的使用可靠性。
