Track vibration reduction fastener and assembling method and application thereof
The invention discloses a rail vibration reduction fastener and an assembling method and application thereof, and belongs to the technical field of rail traffic vibration reduction. The rail vibration reduction fastener comprises an insulating buffer base plate, a lower iron base plate, an upper iron base plate and an insulating system; the insulation system comprises an insulation protection plate, a damping limiting block, an under-plate elastic base plate and a locking ring. The lower iron backing plate is provided with a cavity, and the under-plate elastic backing plate is arranged in the cavity; the insulating protective plate wraps the upper surface of the lower iron base plate and extends to the side wall of the cavity; two ends of the lower iron base plate are respectively provided with a first retaining shoulder, and two ends of the upper iron base plate are respectively provided with a second retaining shoulder matched with the first retaining shoulders; the damping limiting block is arranged between the first blocking shoulder and the second blocking shoulder. The fastener can effectively avoid secondary damage of stray current caused by increased current leakage of the rail to the ground due to current conduction on the surfaces of the lower iron base plate and the upper iron base plate through an insulation system, improves the use stability and safety of ballast bed concrete structure steel bars, metal pipelines and electrical equipment along the rail, and prolongs the service life of the ballast bed concrete structure steel bars, the metal pipelines and the electrical equipment along the rail.
本发明公开了一种轨道减振扣件及其装配方法与应用，属于轨道交通减振技术领域，包括：绝缘缓冲垫板、下铁垫板、上铁垫板以及绝缘系统；绝缘系统包括绝缘护板、阻尼限位块、板下弹性垫板以及锁紧环；下铁垫板设置有空腔，板下弹性垫板设置在空腔内；绝缘护板包设在下铁垫板的上表面并延伸至空腔侧壁；下铁垫板两端分别设置有第一挡肩，上铁垫板两端分别设置有与第一挡肩相配合的第二挡肩；阻尼限位块设置在第一挡肩与第二挡肩之间。该扣件通过绝缘系统能够有效避免下铁垫板与上铁垫板表面电流导通而增大轨对地的电流泄漏，从而引起杂散电流的次生危害，提高了道床混凝土结构钢筋、金属管路以及轨道沿线电气设备的使用稳定性、安全性以及寿命。
