Technical Field

[0001] This utility model relates to the field of radiographic testing technology, and in particular to a high-frequency, high-voltage gamma-ray flaw detector. Background Technology

[0002] High-frequency high-voltage gamma-ray flaw detectors are devices that use gamma rays to detect and inspect materials for defects. They are widely used in the field of non-destructive testing, especially in industry for inspecting the quality of welding, casting, pipelines, pressure vessels, etc. This equipment can effectively reveal internal defects in materials, such as cracks, voids, and pores, without damaging the materials, hence the name "non-destructive testing".

[0003] In existing technologies, it is difficult to ensure stable installation of flaw detectors during operation, which can lead to movement or tilting of the equipment during use. Therefore, we propose a high-frequency, high-pressure gamma-ray flaw detector. Utility Model Content

One end of the return spring 49 away from the side of the positioning seat 3 is fixedly connected to the circumferential surface of the support shaft 45. The purpose is to ensure that the support shaft 45 can be automatically reset and reduce manual intervention.

[0027] One end of the control shaft 41 is rotatably sleeved with a limiting plate 410. The top of the limiting plate 410 is connected to the inner wall of the positioning seat 3. The circumferential surface of the limiting shaft 411 is slidably connected to the side of the moving sleeve 42. A handle 2 is fixedly connected to the top of the flaw detector body 1. The function of the limiting plate 410 is to limit the displacement distance of the moving sleeve 42. The function of the handle 2 is to facilitate the staff to pick up the flaw detector body 1.

[0028] A handle 412 is fixedly connected to the circumferential surface of the control shaft 41. The side of the force plate 46 is located on the displacement trajectory of the push plate 44. The purpose is to ensure that the movement of the push plate 44 can push the force plate 46. The handle 412 makes it convenient for the operator to turn the control shaft 41.

[0029] The flaw detector body 1 is provided with a protective mechanism 5 on its side. The protective mechanism 5 includes a rotating shaft 51, the circumferential surface of which is rotatably connected to the circumferential surface of the fixed arc plate 48. A protective plate 52 is fixedly connected to the circumferential surface of the rotating shaft 51. A push rod 53 is fixedly connected to the circumferential surface of the mounting arc plate 47. A push groove 54 is provided on the circumferential surface of the protective plate 52.

[0030] A torsion spring 55 is fixedly connected to the circumferential surface of the fixed arc plate 48.

After rotation, the mounting arc plate 47 rotates. 7 coincides with the fixed arc plate 48, and surrounds and fixes the pipe to be inspected, so that the flaw detector body 1 is stably installed. When the mounting arc plate 47 rotates, it drives the push rod 53 to rotate. During the rotation of the push rod 53, it enters the push groove 54 and pushes the protective plate 52. The protective plate 52 rotates through the rotating shaft 51 under force. During the rotation, the protective plate 52 protects the working flaw detector body 1. When the flaw detection is completed, the operator rotates the control shaft 41 in the opposite direction, so that the push inclined plate 44 moves away from the side of the force plate 46, so that the mounting arc plate 47 is automatically reset by the return spring 49, and the protective plate 52 is automatically reset by the torsion spring 55, so that the flaw detector body 1 can be removed.
