[0017] As Figure 1 , Figure 2 and Figure 3 The equipment mainly includes a stable base 1, and the front end of the base 1 is fixedly installed with a slide rail 2, the slide rail 2 extends along the length direction of the base 1 and is used for supporting and guiding subsequent components.

[0018] A support frame 3 is slidably installed on the slide rail 2, and the support frame 3 can move back and forth along the slide rail 2 to adapt to steel pipes of different lengths. The upper part of the support frame 3 is designed as a semicircular arc to facilitate the fitting of the outer contour of the steel pipe. An on-center clamp 4 is fixedly installed on the support frame 3, and the on-center clamp 4 includes an outer ring 41, an inner ring 42 and three clamping jaws 43. Three radial slots 411 are uniformly formed on the outer ring 41 and are used for accommodating one end of the clamping jaw 43, and three circumferential slots 421 are correspondingly formed on the inner ring 42 and are used for being connected with the other end of the clamping jaw 43. When the inner ring 42 rotates, the clamping jaw 43 will slide in the radial slot 411 and the circumferential slot 421, so that the clamping jaw 43 clamps or releases the steel pipe.

[0019] The support frame 3 is internally provided with a support bin 6, which is thin and cylindrical and has a through hole 61 in the middle, the size of the through hole 61 matches the outer diameter of the steel pipe to be detected, and is used for supporting the steel pipe.
