The invention discloses an automatic retractable intelligent wheel stopper for rail transit, which is characterized in that a hydraulic control box and an automatic wheel stopper are mounted on a frame at the ends of front and rear wheels, a vehicle-mounted hydraulic system and a hydraulic oil tank module are integrated in the hydraulic control box to supply and return oil, and a motor drives a variable pump to work; the variable pump outputs high-pressure oil to a loop distribution box module through a hydraulic pipeline, the high-pressure oil output by the loop distribution box module supplies oil to a first three-position four-way reversing valve to drive a piston rod of a hydraulic cylinder to stretch, retract and release, the high-pressure oil supplies oil to a second three-position four-way reversing valve to drive a rotary motor to rotate and swing, and automatic retracting and releasing of the wheel stopper are completed. According to the invention, automatic folding and unfolding and online intelligent monitoring of the wheel stopper of the railway vehicle are realized, so that the use safety of the wheel stopper is greatly improved.

    本发明公开了一种轨道交通自动收放智能化止轮器,具体为:液压控制箱和自动止轮器安装在前后车轮端部的车架上,液压控制箱内集成了车载液压系统,液压油箱模块供回油,电机带动变量泵工作,变量泵通过液压管路向回路分配箱模块输出高压油,回路分配箱模块输出的高压油向三位四通换向阀一供油驱动液压缸的活塞杆的伸缩收放动作,向三位四通换向阀二供油驱动回转马达的回转摆动,完成止轮器的自动收放。本发明实现轨道车辆止轮器的自动收放、在线智能监控,从而极大的提高了止轮器使用的安全性。
