The invention discloses an urban rail emergency evacuation ramp locking device, which is composed of an emergency evacuation ramp and a bent rod assembly. The emergency evacuation ramp comprises pedallocks, lock frames, a pedal, lock stops and a ramp recovery apparatus. The pedal locks and the lock frames are located at the front end of the emergency evacuation ramp, and the lock stops are located in front of the ramp recovery apparatus; the bent rod assembly is composed of two bent rods, and each bent rod is provided with a handle; when the emergency evacuation ramp is in a retracting state,the bent rod assembly is inserted into the lock frames and the lock stops, and the emergency evacuation ramp is locked. When the emergency evacuation ramp is in a retracting state, after the bent rodassembly is inserted into the lock frames on two sides of the emergency evacuation ramp and the lock stops located in front of the ramp recovery apparatus, the bent rod assembly cannot be unfolded under the action of an external force, and accidents are prevented. The handles are arranged on the bent rod assembly, and can avoid the injury risk caused by direct contact between the hands of an operator and the emergency evacuation ramp when the emergency evacuation ramp is operated to be opened.

    本发明公开了一种城轨紧急疏散坡道锁紧装置,由紧急疏散坡道和弯杆组件组成;所述紧急疏散坡道包括踏板锁、锁框、踏板、锁档和坡道回收装置,所述踏板锁和锁框位于所述紧急疏散坡道的前端,所述锁档位于所述坡道回收装置前方;所述弯杆组件由两件弯杆组成、每件弯杆上分别设有手柄;当所述紧急疏散坡道处于收回状态时,弯杆组件插入锁框和锁档,锁定紧急疏散坡道。当紧急疏散坡道处于收回状态时,弯杆组件插入紧急疏散坡道两侧的锁框和位于坡道回收装置前方的锁档后,在外力的作用下不会展开,防止意外发生;弯杆组件上设有手柄,用于操作紧急疏散坡道打开时,避免操作人员的手与紧急疏散坡道直接接触而产生的受伤风险。
