Description

Technical Field

[0001] The utility model relates to the technical field of ray detection, and more specifically, to a ray detection auxiliary support. Background Art

[0002] It is known that stainless steel pipes with the characteristics of corrosion resistance, high temperature resistance and high strength are widely used in the systems of thermal power plants; among them, it is crucial to perform post-weld inspection on the welds of stainless steel during the installation process. Since the austenitic stainless steel joints may have the problem of coarse grain during the welding process, if ultrasonic testing is used, the results are inaccurate; compared with ultrasonic testing, ray detection is sensitive to circular and point defects. Therefore, the detection of stainless steel butt welds mainly relies on ray detection; for ferromagnetic materials, when performing ray detection, the ray machine needs to be fixed on the negative film of the object to be detected for irradiation.

[0003] However, in actual ray detection, due to environmental factors, many tube rows are located in various positions, thus optimizing the irradiation of the ray machine has become a difficult problem in the detection process; in actual operation, most use welded iron frames or suspension ropes for fixation: when using an iron frame, due to the different heights, there will be a situation where one welding frame is not enough, so that personnel need to carry multiple welding frames or carry a welding torch for on-site welding; when using a suspension rope, it is easily affected by the external environment, resulting in shaking during the irradiation of the ray machine, making the negative film blurred, thus resulting in a high detection time cost, high limitations and low work efficiency; therefore, a ray detection auxiliary support is proposed as a further improvement to facilitate the detection of stainless steel pipe welds by detection personnel.

[0094] First, open the buckle 15, put the ray machine into the ray machine outer casing 1, and the ray machine wiring extends through the strip hole 16 and is connected to the ray machine. After the ray machine is installed, close the ray machine outer casing 1 and close the buckle 15;
