DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The evacuation pedal device for urban vehicles for rail transit of the present invention comprises a sliding frame 1, a pedal 7, and a connecting frame 12; the connecting frame 12 is assembled on the sliding frame 1 through a roller group 13, the pedal 7 is connected to the sliding frame 1 through a pin 16, a connecting rod 1 5, and a connecting rod 2 6, the pedal 7 is connected to the connecting frame 12 through a pin 16 and a gas spring 4, and the pedal 7 is connected to a cam 15; the sliding frame 1 is connected to one end of a steel wire rope 1 3, and the other end of the steel wire rope 1 3 is connected to the cam 15; the sliding frame 1 is connected to one end of a steel wire rope 2 8, and the other end of the steel wire rope 2 8 is connected to the pedal 7 after passing through a pulley 17.

[0023] The sliding frame 1 of the present invention is connected to the vehicle body by bolts. The sliding frame 1 is provided with a mechanical lock assembly 2. The sliding frame 1 is provided with a plurality of sets of synchronous wheels 9 and synchronous belts 10. The synchronous wheels 9 and the synchronous belts 10 are arranged in parallel. The synchronous wheels 9 and the synchronous belts 10 are driven by a motor 11. A baffle 14 is provided on the side of the connecting rod 15. The vehicle body is a rail transit urban vehicle, and the sliding frame 1 is installed at the passenger compartment door of the vehicle body.

[0024] The usage process is as follows: when unfolding, the mechanical lock assembly 2 is unlocked by electric or manual operation, and the motor 11 drives the synchronous belt 10 to be pushed out to the extended state; at the same time, the gas spring 4 and the baffle 14 push the pedal 7 to the use state; when retracting, the steel wire rope 8 pulls the pedal 7 back by electric or manual operation, and the connecting frame 12 runs under the pull of the synchronous belt 10, and after colliding with the mechanical lock assembly 2, the pedal is automatically locked.

[0025] The main body of the present invention belongs to a multi-link design scheme, which can meet the functions of translation, lifting and telescopic. The internally embedded six-link structure can meet the up and down telescopic movement of the pedal. With a mechanical lock assembly, after it is recovered in place, the pedal assembly is locked by the mechanical lock. When the urban vehicle evacuation pedal device is opened, the mechanical lock is unlocked electrically, and then the motor drives the synchronous belt to push the sliding frame out, and the pedal is opened by the baffle and gas spring. With an emergency unlocking device, it is connected to the mechanical lock assembly through an electromagnet and a wire rope, respectively, and can realize electric or manual unlocking. It can adapt to the installation interface of different door systems, which is simple and convenient, and simple to debug and maintain.

[0026] The present invention unlocks by electric or manual means, moves the sliding frame to the use state under the action of the motor, and lifts and unfolds the pedal assembly under the action of the gas spring and the sliding frame baffle to reach the use state. The pedal of the present invention has a simple structure and a large load-bearing capacity; it is easy to operate without electricity or gas, and has high safety and reliability in emergency situations. The present invention is used for rail passenger room doors, has little impact on the size of the existing door system, and can be used for emergency rapid evacuation under various working conditions.
