Locking device for railway container flat car loading

Abstract

The invention discloses a locking device which is used for a rail flat car with shipping containers, and relates to a locking device of a shipping container which is assembled on a rail flat car, in particular to a fully automatic turning-typed locking device of a shipping container. The invention comprises a spin lock, a rotating shaft of a locking head and a baffle, and the key technical points of the invention are that the locking device also has a spin lock base, the top surface of the spin lock base is opened with a dovetail groove, and the spin lock base has a perforated orifice; the locking device further has a lock seat, a cavity is arranged in the middle part of the lock seat, and the inner sides of the two sides of the lock seat are opened with slide slots respectively; the bottom of the spin lock is provided with a dovetail-shaped convex platform, which is embedded into the dovetail groove on the spin lock base, the rotating shaft of the locking head is inserted into the perforated orifice on the spin lock base, two ends of the rotating shaft of the locking head are positioned in the slide slots at two sides of the lock seat respectively, and the baffle is arranged at the other end of the lock seat by a baffle rotating shaft. The structure of the invention is simpler, more reasonable and firmer, and can restrict a shipping container simultaneously along the horizontal and vertical directions.

Description

technical field [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. ...

AI Technical Summary

Problems solved by technology

Due to the assembly and welding structure of this locking device, there are many parts, the structure is complicated, and the installation is difficult.

Since the torsion lock is welded on the lock pad plate, and the lock shaft is welded to the bottom surface of the lock pad plate, the vertical bearing capacity and longitudinal impact of the torsion lock on the container are transmitted to the front and rear support plates, so that the entire locking device does not Not solid

And the locking device of this structure is not firm to the restraint of twist lock, there is potential safety hazard
