[0006] The mechanical lock mounting bracket is fastened to the external vehicle evacuation device by bolts.

[0007] The vehicle evacuation device is located on the rail transit train.

[0008] The lock hook is provided with a torsion spring one and a torsion spring two on its side, and the torsion springs are connected to a cylindrical pin.

[0009] The stop mounting shaft is equipped with a washer.

[0010] The switch bracket is equipped with a limit switch.

[0011] The switch pad is fastened to the mechanical lock mounting bracket by an M4 socket head cap screw and a washer.

[0012] The electromagnet is fixed by a hexagonal head bolt M4.

[0013] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention uses an electromagnet to realize the automatic opening of the pedal and achieve the use state; the pedal lock is simple, has a large load-bearing capacity, and is highly reliable; it is easy to operate, has high safety in emergency situations, and can be manually operated in the case of no electricity or gas; it is suitable for track passenger compartment doors, has little impact on the size of existing door systems, and can be used in a variety of working conditions.

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] The present invention relates to a pedal lock device for rail transit, comprising a mechanical lock mounting bracket 1, a lock hook 2, a lock hook mounting shaft 3, a pull cable disc 4, a stop mounting shaft 5, a mechanical lock block 6, a switch bracket 7, a switch pad 9, an electromagnet 10, and a pull plate 18; the lock hook mounting shaft 3, the stop mounting shaft 5, the switch pad 9, and the electromagnet 10 are mounted on the mechanical lock mounting bracket 1; the lock hook 2 and the pull cable disc 4 are respectively matched with the lock hook mounting shaft 3 and the stop mounting shaft 5; the switch bracket 7 is fixed on the mechanical lock block 6, one end of the mechanical lock block 6 is matched with the stop mounting shaft 5, and the other end of the mechanical lock block 6 is connected to the pull plate 18.

[0021] The mechanical lock mounting bracket 1 of this utility model is fastened to the external vehicle evacuation device by bolts. The vehicle evacuation device is located on the rail transit train. The side of the lock hook 2 is provided with a torsion spring 13 and a torsion spring 15, which are connected to a cylindrical pin 12. The stop mounting shaft 5 is provided with a washer 14. The switch bracket 7 is provided with a limit switch 8. The switch pad 9 is fastened to the mechanical lock mounting bracket 1 by an M4 socket head cap screw 16 and a washer 17. The electromagnet 10 is fixed by an M4 socket head cap screw 11.

[0022] The specific usage process is as follows: When deployed in an emergency, the electromagnet 10 is energized by a signal, and the electromagnet 10 pulls the pull plate 18 upward. The pull plate drives the mechanical lock stop 6 to disengage from the mating surface of the lock hook 2. Under the action of the torsion spring 13, the lock hook 2 rotates counterclockwise by a certain angle to complete the unlocking. When retracted in an emergency, the personnel push the pedal to the position of the lock hook 2. The lock hook 2 rotates clockwise by a certain angle through the collision of the pin shaft. The mechanical lock stop 6 holds the lock hook to complete the locking.
