[0002] The most commonly used non-destructive testing method for industrial product pressure vessels is radiographic testing. Radiographic testing can obtain intuitive images of defects and accurately locate them. When using radiographic testing instruments, it is necessary to use a fixed bracket to fix the radiographic testing instrument, so that the testing instrument can be close to different positions of the pressure vessel.

[0003] Chinese patent CN220473409U discloses a protective device for an X-ray flaw detector, including an X-ray flaw detector body mounted on a support rod, a slide seat that can move up and down is mounted on the support rod, a rotating block is hinged on one side of the slide seat, two brackets are fixed on the rotating block, the upper sides of the two brackets are respectively connected to a top frame by bolts, the X-ray flaw detector body is located between the bracket and the top frame, a vertical groove is opened on the support rod, and a threaded rod is fixed on the slide seat.

[0004] The above patent adjusts the angle of the X-ray flaw detector body through a threaded rod, but the adjustment angle of the X-ray flaw detector body can only be horizontal and obliquely downward, and the X-ray flaw detector body cannot be adjusted obliquely upward (the flaw detector cannot be obliquely upward toward the pressure vessel, which is inconvenient to detect flaws in the arc below the side of the pressure vessel), and the range of angle adjustment is small, which reduces the practicality of the device. Therefore, a technical measure is proposed to solve the problem that the adjustment angle of the X-ray flaw detector body can only be horizontal and obliquely downward, and the X-ray flaw detector body cannot be adjusted obliquely upward, and the range of angle adjustment is small, which reduces the practicality of the device.
