Device for reducing point rail conversion force of movable point rail frog
The invention belongs to the technical field of rail transit and relates to a device for reducing the point rail conversion force of a movable point rail frog. The device comprises a point rail assembly and a positioning assembly; the point rail assembly comprises a sleeper, wing rails, a long point rail and a short point rail; the wing rails are fixedly connected with the sleeper; the wing railsare divided into two group; each wing rail group comprises two wing rails, wherein the two wing rails are symmetrically arranged on the upper side and the lower side of the sleeper; and the long pointrail is rotationally connected with the sleeper and located between the two wing rail groups; the long point rail and the short point rail are placed between the two wing rails in an initial state; the distances between the end parts of the long point rail and the short point rail and the two side wing rails are the same; when conversion equipment drags the long point rail and the short point rail to be tightly attached to the wing rails and the sleeper; the stroke of the long point rail and the short point rail is reduced by half, so that the conversion force of the long point rail and the short point rail is effectively reduced, meanwhile, the problem that the point rail conversion force of an existing movable point rail frog is too large is solved, the signal failure rate of a point switch is reduced, and smooth point rail conversion, in-place point rail conversion and driving safety are guaranteed.
本发明适用于轨道交通技术领域，提供了一种减少可动心轨辙叉心轨转换力的装置，包括心轨组件和定位组件，心轨组件包括轨枕、翼轨、长心轨和短心轨，所述翼轨与轨枕固定连接，翼轨包括两组，每组翼轨包括两根翼轨，两根翼轨对称设置于所述轨枕的上下两侧，所述长心轨与所述轨枕转动连接，且位于两组所述翼轨之间；将长心轨和短心轨初始状态摆放在两根翼轨中间位置，长心轨和短心轨的端部与两侧翼轨的间距相同，使得转换设备牵引长心轨和短心轨至与翼轨轨枕密贴时，长心轨和短心轨的动程减少了一半，从而有效降低长心轨和短心轨的转换力，同时解决现有可动心轨辙叉心轨转换力过大问题，减少转辙机信号故障率，确保心轨转换顺畅、到位和行车安全。
