Urban rail transit elastic split fastener system with retaining shoulder
The invention discloses an urban rail transit elastic split fastener system with a retaining shoulder. An iron base plate and an under-plate base plate apply downward buckling pressure through screw spikes and are arranged on a sleeper/rail plate with the retaining shoulder. Meanwhile, the transverse baffle and the elastic buckling base plate are buckled and limited on two sides in the sleeper/track plate bearing groove through the iron base plate. An under-rail base plate and a steel rail are respectively arranged on the iron base plate, a right-angled insulation gauge block is arranged on the outer side of the steel rail corresponding to the T-shaped bolt, and the lower portion of the T-shaped bolt is located in a corresponding T-shaped groove of the iron base plate. The omega-shaped elastic strip is pressed by the T-shaped bolt, one end of the omega-shaped elastic strip is buckled on the insulation gauge block for fixing the steel rail, the other end of the omega-shaped elastic strip is buckled on the iron base plate, and then torque force of the T-shaped bolt is transmitted to the steel rail and the iron base plate step by step. The technical problems that national railway shoulder blocking fasteners are inconvenient to adjust, the maintenance workload is relatively large, the service life of part of parts is short, and the specifications of gauge adjusting parts are largecan be solved.
本发明公开了一种城市轨道交通有挡肩弹性分开式扣件系统，铁垫板和板下垫板通过螺旋道钉施以向下的扣压力，安装于有挡肩轨枕/轨道板上。同时横向挡板和弹性扣压垫板通过铁垫板扣压限位于轨枕/轨道板承轨槽内部两侧。在铁垫板上分别安放轨下垫板、钢轨，钢轨外侧对应于T型螺栓处设有直角状的绝缘轨距块，T型螺栓的下部位于铁垫板的对应T形槽内。ω型弹条被T型螺栓压紧，ω型弹条一端扣压在固定钢轨的绝缘轨距块上、另一端扣压在铁垫板上，进而将T型螺栓的扭矩力逐级传递至钢轨和铁垫板上。本发明可以解决国铁挡肩扣件调节不便、养护维系工作量相对较大、部分零部件使用寿命短、轨距调整零部件规格较多等技术问题。
