Description

Technical Field

[0001] The utility model relates to the technical field of nondestructive testing devices, in particular to a nondestructive testing device for a pressure vessel. Background Art

[0002] Pressure vessels are widely used in production and life fields such as machinery, petroleum, and chemical industry. They are one of the high-risk pressure-bearing special equipment. Once an explosion or leakage occurs, it usually causes a destructive accident. Therefore, non-destructive testing of pressure vessels after production and use is particularly important.

[0003] According to a nondestructive testing device for pressure vessels disclosed in application number 202010666110.7, it includes a base plate, a U-shaped frame and a collar, U-shaped frames are symmetrically installed at both ends of the base plate, a guide rod is horizontally fixed between the two U-shaped frames, and sliding sleeves are installed on both sides of the collar, which are slidably mounted on the guide rods. A gear ring is rotatably embedded on the inner side of the collar, and a detection probe is installed on the gear ring. A second motor is installed on the outer wall of the collar, and a gear meshing with the gear ring is installed on the output end of the second motor; a translation mechanism that drives the collar to slide horizontally is also installed between the two side brackets, and a support frame for supporting the pressure vessel is provided on the base plate. The nondestructive testing device for pressure vessels drives the detection probe to translate and rotate circumferentially through the translation mechanism, thereby realizing all-round detection of the pressure vessel, with a wide detection coverage, avoiding the existence of detection blind spots, improving the accuracy of the detection results, and ensuring product quality.

[0004] The above patent realizes all-round detection of pressure vessels with a wide detection coverage, avoids detection blind spots, improves the accuracy of detection results, and ensures product quality. However, the above patent only uses a single support rod to fix the pressure vessel, which can easily cause unstable placement of the pressure vessel and cannot be adjusted according to the length of the pressure vessel, resulting in reduced practicality. For this reason, we propose a non-destructive testing device for pressure vessels. Utility Model Content
