[0002] The stainless steel pool in a nuclear power plant belongs to nuclear-grade equipment. Its main function is to provide a clean environment for the operation of nuclear equipment and prevent radioactive substances from penetrating into the internal concrete structure of the nuclear power plant. The quality of the construction of the stainless steel pool directly affects the safety of the operation of the nuclear power plant. Therefore, 100% non-destructive testing is required for the welds of the stainless steel pool. X-ray detection technology is an extremely important non-destructive testing method, and its application range is extremely wide. As long as it is a unit engaged in non-destructive testing work, it will conduct research on the X-ray machine-assisted film shooting device.

[0003] When performing X-ray film shooting on the butt welds of large stainless steel pools, in the commonly used auxiliary tooling, one is to set up a steel pipe operation frame on a large operation platform to pad up the X-ray machine according to the height required by the X-ray machine, and the other is to place several wooden boxes on the large operation platform to pad up the X-ray machine according to the height required by the X-ray machine. However, when using both toolings, due to the movement of the inspection personnel on the large operation platform, the large operation platform will shake, resulting in the shaking of the steel pipe operation frame or the wooden box, and then the X-ray machine on the steel pipe operation frame or the wooden box will shake, making the taken negative film unqualified, resulting in a large amount of rework. Moreover, there are problems in positioning, focusing, and distance setting of the X-ray machine on the vertical wall of the large stainless steel pool, wasting a lot of manpower and material resources and having low work efficiency; even it is impossible to ensure the sufficient stability and safety of the X-ray machine. It is very likely that the X-ray machine will shake when the inspection personnel move, causing the inspection personnel to be irradiated by X-rays and resulting in radiation protection incidents.
