Damping fastener for urban rail transit
The invention belongs to the technical field of rail transit, and in particular relates to a damping fastener for urban rail transit. The damping fastener comprises two elastic strips which are used for buckling and pressing a steel rail, anchor bolts which are arranged on the two sides of the steel rail, and an iron base plate, an elastic base plate and a base plate which are sequentially arranged between the steel rail and a sleeper. The anchor bolts sequentially penetrate through the iron base plate, the elastic base plate and the base plate to be connected with a sleeve arranged in the sleeper; the anchor bolt above the base plate is sleeved with a nesting sleeve, the lower surface of the nesting sleeve abuts against the upper surface of the base plate, the upper surface of the nestingsleeve is higher than the upper surface of the iron base plate, the nesting sleeve is provided with a cover plate in a pressed mode, the anchor bolt is sleeved with the cover plate, and the cover plate is provided with one or more non-metal elastic washers arranged on the upper surface of the iron base plate. Steel rail vibration can be effectively reduced, noise is reduced, rail smoothness is guaranteed when a train passes, and the phenomenon of train shaking is avoided.
本发明属于轨道交通技术领域，特指一种城市轨道交通用减振扣件，包括用于扣压钢轨的两个弹条、设置在钢轨两侧的锚固螺栓、以及依次设置在钢轨和轨枕之间的铁垫板、弹性垫板和基板，锚固螺栓依次穿过铁垫板、弹性垫板和基板与设置在轨枕内的套管连接，所述基板上方的锚固螺栓上套装有嵌套，所述嵌套的下表面与基板的上表面相抵触、上表面高出铁垫板的上表面，所述嵌套上压设有套装在锚固螺栓上的盖板，所述盖板上设有一个以上压设在铁垫板上表面的非金属弹性垫圈。本发明能有效减少钢轨振动，减少噪声，保证列车通过时的轨道平顺性，避免晃车现象的发生。
