Retaining-shoulder-free fastener for urban rail transit
The invention discloses a retaining-shoulder-free fastener for urban rail transit. The fastener comprises an iron base plate, an insulating buffer base plate, an under-rail base plate, an insulating gauge block, an elastic strip, a first bolt fastener, a second bolt fastener, a flat cushion block and an embedded sleeve. The insulating buffer base plate and the iron base plate are sequentially laidon a sleeper top from bottom to top. Bolt through holes are arranged in opposite corners of the insulation buffer base plate and the iron base plate, the flat cushion block is further arranged on theiron base plate, a sawtooth structure is formed at an attaching position of the flat cushion block and the iron base plate, and a first bolt fastener sequentially penetrates through the flat cushionblock, the iron base plate and the insulation buffer base plate to be screwed into the embedded sleeve. Iron bases are arranged at the other opposite corners of the iron base plate, and the second bolt fasteners abut against and fix the elastic strips to the iron bases; and the insulation gauge block is embedded and fixed between a steel rail and the iron bases. The fastener is a great improvementon an existing fastener for subways and fasteners for high-speed rails, and is simple in structure, reasonable in design, more suitable for urban rail transit systems and good in application prospect.
本发明公开了一种城市轨道交通用无挡肩扣件，包括：铁垫板、绝缘缓冲垫板、轨下垫板、绝缘轨距块、弹条、第一螺栓紧固件、第二螺栓紧固件、平垫块和预埋套管；绝缘缓冲垫板和铁垫板自下而上依次铺设在轨枕顶部，且绝缘缓冲垫板和铁垫板的对角处均形成有螺栓贯通孔，铁垫板上还设有平垫块，平垫块与铁垫板贴合处形成有锯齿结构，第一螺栓紧固件分别依次穿过平垫块、铁垫板和绝缘缓冲垫板旋入预埋套管内；铁垫板的另一对角处设有铁座，第二螺栓紧固件将弹条抵接固定在铁座上；绝缘轨距块嵌设固定于钢轨和铁座之间。该扣件是对现有的地铁用扣件及高铁用扣件作出的巨大改进，其结构简单，设计合理，更加适用于城市轨道交通系统，应用前景好。
