[0002] A radiographic flaw detector is a special testing instrument used in the field of mechanical engineering. It is mainly used to detect internal defects in materials or products. The radiographic flaw detector uses the principle that X-rays or gamma rays penetrate matter and produce fluorescence or visible light inside the matter to achieve non-destructive testing of the internal structure of an object. Depending on the type of rays, radiographic flaw detectors can be divided into X-ray flaw detectors and gamma-ray flaw detectors. In addition, depending on portability, they can also be divided into portable radiographic flaw detectors and fixed radiographic flaw detectors. For example, a gamma-ray flaw detector can be used to perform flaw detection operations on the welds of a pipeline in order to check whether there are defects such as bubbles in the welds. At the same time, an adjustment device is required to adjust the position of the gamma-ray flaw detector.
[0003] When the existing adjustment device is in use, when the gamma-ray flaw detector is detecting multiple welds of a steel pipe that has been welded multiple times, the adjustment device cannot automatically install the darkroom at the weld, and it is mostly installed manually, which increases the workload and reduces the flaw detection efficiency of the flaw detector. When the existing adjustment device is in use, the position of the flaw detector is mostly moved manually, and then the flaw detector is fixed to the steel pipe with a rope, which further reduces the flaw detection efficiency of the flaw detector. In view of the above problems, the inventor proposes a gamma-ray flaw detector adjustment device and an adjustment method thereof to solve the above problems. Summary of the invention
