[0001] The invention relates to a locking device for loading on a railway container flat car, relating to a container locking device assembled on a railway flat car, in particular to a flip-type full-automatic container locking device. Background technique

[0002] At present, my country's railway transport containers mostly use straight or convex container locks. These two locks do not require manual operation when loading and unloading containers, but because they can only restrain containers in the horizontal direction, and have no restraint on containers in the vertical direction, there is safety. Hidden danger. Container tipping accidents may occur in poor operating conditions. Patent No. 20062013384.9 discloses a "overturn locking device for railway container vehicles", which welds the torsion lock on the lock pad plate, welds the lock shaft to the bottom surface of the lock pad plate, and inserts the lock shaft into the front and rear support plates. ...
