Switch type elastic strip fastener system for urban railway
The invention relates to a switch type elastic strip fastener system for urban railways. The system comprises a switch type elastic strip (2), an iron base plate (3), a coupling plate (4), an under-rail base plate (5) and an anchor bolt (7), wherein the iron base plate (3) is positioned between the under-rail base plate (5) and the coupling plate (4) and is fixed on a sleeper through the anchor bolt (7), and the iron base plate (3) is provided with a butterfly spring seat (301), the switch type elastic strip (2) comprises a side limb (201) and a middle pressing ring (203), and the side limb (201) and the middle pressing ring (203) enter from the two sides and the middle of the outer side of the butterfly elastic strip base (301) of the iron base plate (3) respectively and finally fix the steel rail (1). Compared with the prior art, the overall installation height of the system is reduced, the size is reduced, the cost is reduced, the friction force between the elastic strip installation process and the elastic strip base is small due to the installation structure and the disassembly and assembly position of the iron base plate, the operation and maintenance process of the fastener system is safe and efficient, and the fastener system can adapt to the line speed of 0-350 km/h.
本发明涉及一种市域铁路用开关式弹条扣件系统，包括开关式弹条(2)、铁垫板(3)、耦合板(4)、轨下垫板(5)、锚固螺栓(7)，所述铁垫板(3)位于轨下垫板(5)及耦合板(4)之间，并通过锚固螺栓(7)固定于轨枕上，所述的铁垫板(3)上设置了蝴蝶弹条座(301)，所述的开关式弹条(2)包括侧肢(201)及中压环(203)，侧肢(201)及中压环(203)分别从铁垫板(3)的蝴蝶弹条座(301)外侧两边及中间进入并最终固定钢轨(1)。与现有技术相比，本发明系统整体安装高度降低，积减小，成本降低，且铁垫板设置的安装结构及拆装位置使得弹条安装过程与弹条座之间的摩擦力小，扣件系统的运维过程安全高效，可适应线路速度0～350km/h。
