Accelerator position adjusting mechanism and electronic induction accelerator shielding container

Abstract

The invention provides an accelerator position adjusting mechanism and an electronic induction accelerator shielding container. The adjusting mechanism comprises a fixing plate and an operation piece. The fixing plate is installed on the base wall of an accommodation cavity of the electronic induction accelerator shielding container, is capable of sliding in the left and right directions relative to the base wall of the accommodation cavity and is used for fixing an electronic induction accelerator. A through hole is arranged in the left end and / or the right end of the side wall of the accommodation cavity. The first end of the operation piece passes through the through hole and is matched with the fixing plate. The second end of the operation piece is arranged outside the electronic induction accelerator shielding container, and used for driving the fixing plate to slide in the left and right directions relative to the base wall of the accommodation cavity. According to the invention, positions of the electronic induction accelerator can be easily adjusted outside the shielding container without disassembling an upper cover of the shielding container, so difficulty level of position adjustment work of the accelerator is greatly reduced, workload is reduced and time consumed for adjusting the position of the accelerator can be shortened.

Description

technical field [0001] The invention relates to the field of radiation scanning inspection, and more specifically relates to an accelerator position adjustment mechanism and a betatron shielding container with the accelerator position adjustment mechanism. Background technique [0002] In the prior art, some radiation scanning inspection systems use betatrons to produce rays, and the rays generated by the betatrons are 4pi spherical, so it is necessary to shield the useless rays outside the solid angle of the imaging fan beam direction, so the betatrons need to be Installed in the shielding container, the shielding container is provided with a ray outlet, the imaging ray fan beam is emitted from the ray outlet, and the redundant rays are shielded by the shielding container. However, after the betatron is installed in the shielding container, if the ray emission port of the accelerator is not aligned with the ray outlet on the shielding container, the amount of radiation emit...

AI Technical Summary

Problems solved by technology

However, after the betatron is installed in the shielding container, if the ray emission port of the accelerator is not aligned with the ray outlet on the shielding container, the amount of radiation emitted from the ray outlet of the shielding container will be insufficient. At this time, it is necessary to open the top of the shielding container The cover adjusts the position of the accelerator, and the adjustment work may need to be repeated many times to achieve the desired effect, but the upper cover of the shielding container is very heavy, and it needs to be lifted by mechanical lifting when disassembling and assembling, which leads to a large workload for adjusting the position of the accelerator , takes a long time
