Self-locking device for platform trailer in radiation imaging inspection system
Technical Field
The invention relates to a self-locking device, in particular to a self-locking device for a flat trailer in a radiation imaging inspection system.
Background
In the field of radiation imaging inspection, stationary container inspection equipment employs a trailer arrangement, known in the industry as a flatbed trailer.
Before the vehicle is inspected, the inspected vehicle needs to drive onto a platform trailer, then passes through a radiation imaging inspection area at a constant speed under the traction of the platform trailer, and after the inspection is finished, the vehicle drives away from the area.
In the process, the inspected vehicle needs to frequently go up and down the platform trailer, and the inspected vehicle is often a heavy truck, so that the impact force on the platform trailer is very large. A means is therefore required to secure the flatbed trailer to prevent the vehicle inertia from impacting the overall traction system.
The fixing device adopted at present can not be self-locked, and has high requirement on the accuracy of a parking position. The use requirement of the flat trailer adopting the steel wire rope as traction can not be met.
