Low-height split type vibration reduction fastener and mounting method thereof
The invention discloses a low-height split type vibration reduction fastener and an installation method thereof.The vibration reduction fastener comprises a sleeper and an embedded sleeve, and an insulating buffer base plate, an iron base plate, a lower elastic base plate and an iron base plate are sequentially arranged on the sleeper; an insulating buffering base plate, an iron base plate lower elastic base plate and an iron base plate are fixed to a sleeper through anchor bolts with spring washers, bottom linings and connecting sleeves are arranged at the joints of the anchor bolts and the iron base plate lower elastic base plate and the joints of the anchor bolts and the iron base plate respectively, and an under-rail base plate, a steel rail and an insulating gauge block are arranged on the iron base plate. The steel rail is buckled and pressed on the iron base plate through the elastic strips, the T-shaped bolts and the nuts. A single-layer iron base plate and a separated fastener structure are adopted, the overall installation height of the fastener is low, the system stability of the fastener is improved, meanwhile, the connecting mode of the bottom lining and the connecting sleeve is adopted at the connecting position of the anchor bolts, the pre-compression amount of the elastic base plate below the iron base plate can be effectively controlled, and the service life of the elastic base plate is prolonged. And it is ensured that the fastener system still has good elasticity in the service process.
本发明公开了一种低高度的分开式减振扣件及其安装方法，减振扣件包括轨枕及预埋套管，在轨枕上依次设置绝缘缓冲垫板、铁垫板下弹性垫板和铁垫板，采用带弹簧垫圈的锚固螺栓将绝缘缓冲垫板、铁垫板下弹性垫板和铁垫板固定在轨枕上，在锚固螺栓与铁垫板下弹性垫板和铁垫板的连接处分别设置底部衬套和连接套，在铁垫板上设置轨下垫板、钢轨和绝缘轨距块，利用弹条、T型螺栓及螺母将钢轨扣压在铁垫板上。本发明采用单层铁垫板和分开式的扣件结构，扣件整体安装高度较低，提高了扣件系统稳定性，同时对锚固螺栓连接处采用“底部衬套+连接套”的连接方式，能够有效控制铁垫板下弹性垫板的预压缩量，保证扣件系统在服役过程中仍具有良好的弹性。
