Locking device for quick de-compiling through passage of high-speed train

Abstract

The invention discloses a locking device for a quick de-compiling through passage of a high-speed train, which comprises a through passage hinge frame and a steel wire. The through passage hinge frame comprises a left frame and a right frame opposite in notch, a lock seat with a hole is fixed into a groove of the right frame, a lock hook with a hole can be inserted into the lock seat in linkage of the through passage and is fixed into a groove of the left frame, an inserting pin component which can be inserted into or removed out of the holes on the lock seat and the lock hook is fixed onto the steel wire, the steel wire is connected with a wrench component which is capable of drawing the steel wire to move through a lock handle, and the wrench component is provided with a rotary lock which can be locked or unlocked and a rotary handle. By means of locking and unlocking of the rotary lock, the handle is rotated to pull the steel wire to move, the inserting pin component is inserted into the holes combined by the lock hook and the lock seat, and accordingly safety and reliability in locking of the quick de-compiling through passage of the high-speed train can be realized. Loosening of the handle after locking can be avoided by means of the rotary lock, high locking stability can be guaranteed, and the operation requirements of quick de-compiling of the through passage can be met.

Description

technical field [0001] The invention relates to a locking device used for the fast decoupling passageway of a high-speed train. Background technique [0002] With the rapid development of CHR high-speed trains, higher requirements have been put forward for the connection and decoupling of train vehicles, and new requirements have been put forward for the through passage connecting two vehicles, which requires that the through passage can realize fast The function of decoding must also ensure the safe and reliable operation of high-speed trains, and the current common locking devices are difficult to fully meet the requirements of high-speed trains. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the deficiencies in the prior art, to provide a locking device for the fast de-knitting passage of high-speed trains, to ensure the safe and reliable locking of the fast de-knitting passage of high-speed trains, and to ...
