Track fastener structure capable of preventing stray current
The invention discloses a rail fastener structure for preventing stray current, which belongs to the field of urban rail traffic operation and comprises a T-shaped bolt, an elastic strip, an iron backing plate, an under-rail backing plate, an insulating backing plate, a height adjusting backing plate, an elastic backing plate, an insulating sleeve and an anchor bolt which are sequentially arranged from top to bottom, grooves are formed in the two transverse sides of the under-rail base plate. Insulating paint is sprayed on the surface of the iron base plate. The insulating base plate comprises a first body part, a vertical part and an antifouling part. The vertical part is perpendicular to the periphery of the first body part, and the first body part is provided with a connecting hole corresponding to the anchor bolt so that the anchor bolt can penetrate through the insulating base plate. And the sealing gasket is arranged around the connecting hole. According to the rail fastener structure capable of preventing the stray current, the ground resistance of the rail fastener structure is increased by adopting the methods of top-down, drainage collection, spraying treatment and the like, and pollution of liquid to the fastener is reduced, so that leakage of the stray current is reduced.
本发明公开了一种防杂散电流的轨道扣件结构，属于城市轨道交通运行领域，包括由上至下依次设置的T型螺栓、弹条、铁垫板、轨下垫板、绝缘垫板、调高垫板、弹性垫板、绝缘套筒和与所述绝缘套筒匹配连接的锚固螺栓，轨下垫板横向上的两侧设置有沟槽。铁垫板表面采用绝缘涂料喷涂。绝缘垫板包括第一本体部、立直部和防污部。立直部垂直于第一本体部四周设置，第一本体部对应锚固螺栓开设有连接孔以使锚固螺栓从绝缘垫板中穿过。还包括密封垫圈，密封垫圈设置于连接孔周围。本发明的防杂散电流的轨道扣件结构，采用自上而下、收集排流、喷涂处理等方法增大了钢轨扣件结构的对地电阻，减小了液体对扣件的污染，从而减小了杂散电流的泄露。
