The invention discloses a drum recovery device for an urban rail vehicle emergency evacuation ramp. The drum recycling device for the urban rail vehicle emergency evacuation ramp comprises a vehicle head, a door frame is fixedly connected to the vehicle head, a pedal is installed at the bottom of the vehicle head, the pedal is connected with the emergency evacuation ramp through a hinge, and a first mounting base and a second mounting base are fixedly installed on the two sides of the top end face of the emergency evacuation ramp in the width direction. The first mounting base is fixedly connected with one end of a recycling rope through a circular ring, the other end of the recycling rope is connected with a winding drum mechanism fixedly mounted on a headstock, and the second mounting base is fixedly connected with a door frame through an air spring. The pull ring is operated to drive the first pull rod and the second pull rod to enable the ratchet wheel and pawl device to play a role, when the pawl is separated from the ratchet wheel, the emergency evacuation ramp can be unfolded, and when the emergency evacuation ramp is unfolded in place, the pawl is rotated to be located below the ratchet wheel and make contact with the ratchet wheel, and then the pin shaft penetrates through the pull ring and is inserted into a slotted hole of a vehicle head; the emergency evacuation ramp is in a static state, and people can pass through the ramp.
本发明公开了一种城轨车辆紧急疏散坡道用卷筒回收装置,包括车头,车头上固定连接有门框,车头的底部安装有踏板,踏板与紧急疏散坡道通过铰链相连接,紧急疏散坡道的顶端面沿宽度方向两侧均固定安装有第一安装座和第二安装座,第一安装座通过圆环与回收绳的一端固定连接,回收绳的另一端与固定安装在车头上的卷筒机构相连接,第二安装座通过气弹簧与门框固定连接。本发明通过操作拉环,拉环再带动第一和第二拉杆使棘轮棘爪装置发挥作用,当棘爪脱离棘轮,紧急疏散坡道会被展开,当展开到位时,旋转棘爪使棘爪位于棘轮的下方并与棘轮接触,然后用销轴穿过拉环并插入到车头的槽孔中,紧急疏散坡道处于静止状态,人员可以通过。
