Abstract

A retractable locking device for container train comprises a support module, a spin lock module and a limit plate module. The support module comprises a mounting base plate and a vertical through hole which is formed in the mounting base plate. A guiding side plate is arranged on each side of the vertical through hole and positioning grooves are formed in the top end of the guiding side plates. The spin lock module comprises a lock cylinder rod passing through the vertical through hole and a lock head cap is arranged on the top of the lock cylinder rod. A lock base block is sleevingly connected with the lock cylinder rod below the lock head cap. A driven block sleeve which is capable of passing through the vertical through hole is fixed on the bottom part of the lock base block and is provided with block sleeve tooth. A moving push ring is arranged on the lock cylinder rod and is provided with push ring tooth and the push ring tooth is capable of engaging with the block sleeve tooth. An operating handle is hinged at the bottom end of the lock cylinder rod. The limit plat module comprises a steel support, the steel support is hinged to a rotating handle, and a clamping slot limit plate which is capable of cooperating with the operating handle is arranged on the rotating handle. According to this arrangement, the locking requirements for containers in transportation can be achieved and the efficiency of loading and unloading can be improved. The retractable locking device is simple in structure without influencing the previous structure and performance of trains.

Description

technical field [0001] The invention relates to a railway container vehicle, in particular to a telescopic locking device for a railway container vehicle. Background technique [0002] Railway container transportation has the advantages of economy, safety and punctuality. It is a relatively advanced transportation method with good development prospects. The container locking device is an important part of the railway container transport vehicle. It is related to the stability of the container during transportation and the smoothness of the loading and unloading process. It plays a very important role in ensuring the safety of container transportation and improving the efficiency of container loading and unloading. [0003] At present, the conventionally used locking devices for railway containers at home and abroad mainly include straight locks, boss locks, fully automatic twist locks, etc. Some of these locking devices have no locking properties, some have unstable locking ...
