[0002] Rail trains are one of the important means of transportation with a large population throughput. Passenger safety is an important development issue. When an emergency occurs and evacuation is required, the train will travel to the platform ahead and evacuate through the station. After the train stops and the doors and platform doors are opened, passengers should evacuate to the platform under the guidance of station staff. If an emergency occurs during the train's journey and emergency evacuation is required on the spot, there is a safety hazard due to the height difference between the train and the ground, which seriously affects the evacuation efficiency of passengers. At this time, evacuation equipment is needed.

[0003] As a device that can only be used in emergency situations, if it is accidentally turned on, it will interfere with the normal operation of the train and cause major safety accidents.

[0004] The Chinese patent of prior art CN202310941974.9 discloses a novel lifting evacuation ladder for the side door of urban rail vehicles; it includes a frame assembly, a driving mechanism, a rotating arm assembly, a manual operating device, and a pedal assembly: the frame assembly includes a frame component, a guide rail slider pair, and a gas spring, the guide rail slider pair is respectively fixed on both sides of the frame component, and plays a guiding role in the up and down sliding of the pedal assembly, one end of the gas spring is hinged to the frame component, and the other end of the gas spring is hinged to the first-level pedal of the pedal assembly, so that the lifting evacuation ladder can be automatically opened and closed, the operation is simple, and the degree of automation is high. At the same time, it can be used in emergency situations such as power outages, which greatly improves the effect of the train's escape evacuation capability. The scheme lacks protective measures to prevent accidental opening and poses a safety hazard. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a side door evacuation device and a method of using the same, wherein the evacuation device can be prevented from being accidentally opened, thereby avoiding interfering with the normal running of a train and causing a safety accident, and has a high safety factor.

The control unit is used to transmit the deployment or retraction signal. When the control unit receives the deployment signal, the speed measuring element is used to detect whether the train is in a running state. Only when the train stops, the control unit controls one end of the first locking device to disengage from the opening and control the hatch to open.

In the locked state, the raised end of the cam presses on the locking member to prevent the locking member from rotating, thereby causing the locking member to clamp the locking pin; in the unlocked state, the raised end of the cam is away from the locking member, at which time the locking member can rotate freely and the locking pin can freely detach from the locking member.

[0013] As a preferred solution, the evacuation ladder includes a support frame, a lifting rod, a fourth driving device, a flip frame, a first connecting rod, a first pedal, a second pedal and a third pedal.
