Device capable of reducing point rail conversion resistance of movable point rail frog
The invention discloses a device capable of reducing point rail conversion resistance of a movable point rail frog, and relates to the technical field of rail movable point rail frogs, the device comprises a positioning mechanism, a roller mechanism and a point rail supporting piece, the positioning mechanism is transversely arranged below a rail piece at a point rail movable adjusting section, is located between a pair of adjacent sleepers and is arranged along the length direction of the sleepers, and the roller mechanism is arranged on the positioning mechanism. The roller mechanism comprises roller seats and rollers which are symmetrically arranged at the two ends of the positioning mechanism, the roller seats are adjustably fixed to the two ends of the positioning mechanism, the two ends of the point rail supporting piece are arranged on the rollers on the corresponding sides in a rolling mode, the center line position of the point rail supporting piece is connected with the point rail, and the bottom of the point rail supporting piece is suspended. And a clearance is arranged on the surface of the track subgrade. According to the device, the point rail can be lifted from the sliding bed bedplate in the point rail carrying process, so that the friction force between the rail bottom of the point rail and the sliding bed bedplate is reduced, the conversion resistance and the signal failure rate of a point switch are reduced, and smooth and in-place point rail conversion and driving safety are ensured.
本发明公开了一种可减少可动心轨辙叉的心轨转换阻力的装置，涉及轨道可动心轨辙叉技术领，其包括定位机构、滚轮机构和心轨托动件，定位机构横置于心轨可动调整段处的轨件下方，并位于一对相邻枕木之间，沿枕木的长度方向布置，滚轮机构包括对称设在定位机构两端的滚轮座和滚轮，滚轮座可调节地固定在定位机构的两端，心轨托动件的两端滚动设置在对应侧的滚轮上，心轨托动件的中心线位置与心轨连接，心轨托动件的底部悬空设置，与轨道路基表面设有离空间隙。本发明的装置在心轨搬动过程中可将心轨从滑床台板上抬起，从而减少了心轨的轨底与滑床台板之间的摩擦力，降低了转换阻力和转辙机的信号故障率，确保了心轨转换顺畅、到位和行车安全。
