The escape ramp of the railway vehicle comprises a pedal, a connecting rod assembly, a stand column and a rope belt, and is characterized by further comprising a recovery mechanism. The two sets of recycling mechanisms are arranged at the upper ends of the corresponding stand columns correspondingly. The two sets of recycling mechanisms are the same in structure and each comprise a recycling handle, a driving shaft, a mounting shaft, a ratchet wheel, a ratchet wheel limiting assembly and a recycling belt. The number of the ratchet wheels is two, and the two ratchet wheels are the same in structure. The mounting shaft is rotationally arranged at the upper end of the stand column, one end of the recovery belt is fixedly arranged on the mounting shaft, and the other end of the recovery belt is fixedly arranged on the front portion of the corresponding side of the fourth pedal. The two ratchet wheels are fixedly arranged at the left end and the right end of the mounting shaft respectively. The recovery handle is rotationally arranged on the mounting shaft and located between the two ratchet wheels. The recovery handle drives the driving shaft to drive the ratchet wheel to rotate unidirectionally, and after the driving shaft is unlocked, the ratchet wheel rotates freely. The ratchet wheel limiting assembly is used for limiting one-way rotation of the ratchet wheel, and the ratchet wheel freely rotates after unlocking.

    本发明公开了一种轨道车辆的逃生坡道,包括踏板、连杆组件、立柱和索带,其要点是:还包括回收机构。回收机构有两组,两组回收机构分别设置在相应一个立柱的上端上。两组回收机构的结构相同,均包括回收手柄、驱动轴、安装轴、棘轮、棘轮限位组件和回收带。棘轮有两个,两个棘轮的结构相同。安装轴转动设置在立柱的上端上,回收带的一端固定设置在安装轴上,另一端固定设置在第四踏板的相应一侧的前部上。两个棘轮分别固定设置在安装轴的左右两端上。回收手柄转动设置在安装轴轴上,位于两个棘轮之间。通过回收手柄带动驱动轴驱动棘轮单向转动,驱动轴解锁后,棘轮自由转动。棘轮限位组件用于限制棘轮单向转动,解锁后,棘轮自由转动。
