Background

The cobalt 60 gamma ray flaw detector is widely applied to the radiographic inspection of pressure vessels, and when the cobalt 60 gamma ray flaw detector works, a cobalt 60 radioactive source needs to be conveyed from a flaw detector body to the position of an exposure probe at the end part of a source conveying pipe, and then the position of the exposure probe is adjusted to the position for setting the radioactive source to a negative film. When the radiation detection is carried out on the circumferential weld of the pressure vessel, the exposure probe is generally required to be arranged at the central position of the circumferential weld, so that the radiation exposure time of the whole circumferential weld is uniform, the radiation detection of the whole circumferential weld can be completed by one-time exposure, and the position of the exposure probe is not required to be adjusted for many times. However, the diameter of the pressure container is not uniform, and the exposure probe of the cobalt 60 gamma ray flaw detector cannot be adjusted to prevent the flaw detection work from being carried out.

Therefore, how to adjust the height of the fixed exposure probe is a problem to be solved by those skilled in the art.
