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.
Description
technical field [0001] The invention relates to the technical field of rail transit, in particular to a reel recovery device for emergency evacuation ramps of urban rail vehicles. Background technique [0002] The emergency evacuation ramp is an escape device used when the subway vehicle encounters a breakdown and needs to evacuate the people on the vehicle. When evacuating the people in the vehicle, the emergency evacuation ramp is deployed; when there is no emergency, the emergency evacuation ramp is in the recovery state . [0003] The existing emergency evacuation ramp recovery device is installed at the front of the vehicle, and the recovery device is arranged on both sides of the ramp. The recovery device adopts a ratchet pawl structure inside, and the ratchet wrench is used to rotate the shaft end for the ratchet to be pulled and recovered. Pull the emergency evacuation ramp with the rope until the emergency evacuation ramp is in the recovered state. [0004] Howeve...
