[0036] The fixing hoop 1, clamping mechanism 2 and connecting hoop 3 of the above-mentioned technical solution are adopted. When in use, the fixing hoop 1 and the connecting hoop 3 are cooperated and clamped on the steel pipe, and then supported on the steel pipe by the clamping mechanism 2. The crimping screw 23 is rotated by the crimping knob 24 to drive the clamping nut 25 and the crimping connecting rod 26 to move, and then the clamping slide 22 is pushed to slide outside the clamping fixed seat 21, so that the clamping slide 22 is supported on the steel pipe and lifts up the fixing hoop 1, and the sliding seat 42 of the connecting mechanism 4 is pressed to the lowest point when connected, so that the fixing hoop 1 remains tight and more stable after being fixed.

[0037] For further information, see Figures 1 to 9The guide mechanism 5 includes a first guide bar 51 fixed on the outer surface of the fixing hoop 1 and a second guide bar 52 on the outer surface of the connecting hoop 3. A sliding groove 53 is provided on the inner side of the second guide bar 52. A third guide bar 54 is slidably installed on the inner side of the sliding groove 53. The first guide bar 51, the second guide bar 52 and the third guide bar 54 are detected by the detection equipment in cooperation with the guide sliding. The shape of the first guide bar 51 is set to be T-shaped. The position of the third guide bar 54 corresponds to the position of the first guide bar 51, and one end of the third guide bar 54 is engaged with one end of the first guide bar 51. The second guide bar 52 and the first guide bar 51 are both installed on the fixing hoop 1 and the connecting hoop 3 in a toothed shape.

[0039] The working principle and use process of the present invention are as follows: during transportation and storage, the fixing hoop 1 can be stored in a strip shape, and when in use, it can be bent into a ring and sleeved on the steel pipe. Various lengths of connecting hoops 3 can be selected according to the diameter of the steel pipe to cooperate with the fixing hoop 1 and sleeved on the steel pipe. The hook 46 at one end of the hanging rod 45 is hooked on the hanging groove 43 in the sliding seat 42 for connection, and the sliding seat 42 is pressed on the supporting spring 44 for support. At the same time, the auxiliary sliding plate 47 pushes the auxiliary sliding plate 48 to slide and press on the auxiliary spring 49 for auxiliary support, thereby ensuring that the fixing hoop 1 and the connecting hoop 3 are stably pre-hooped next to the welding position of the steel pipe, and then the crimping screw 23 is rotated by the crimping knob 24, thereby cooperating with the thread to drive the clamping nut 25 to move, and the clamping nut 25 drives one end of the crimping connecting rod 26 to move, and then the other end of the crimping connecting rod 26 pushes the clamping slide 22 to clamp The fixing hoop 1 is supported on the fixing seat 21, so that the clamping slide seat 22 and the anti-skid pad 27 are supported on the surface of the steel pipe, thereby supporting the fixing hoop 1 and keeping it tight. The fixing hoop 1 is lifted up by adjusting the clamping mechanism 2 at multiple positions on the fixing hoop 1, so that the hook 46 of the hanging rod 45 is hooked in the hanging groove 43 of the sliding seat 42 more stably, and the sliding seat 42 is pressed against the support spring 44 and the auxiliary spring 49, so that the connection between the fixing hoop 1 and the connecting hoop 3 is tighter. When in use, the detection device is guided to slide on the first guide bar 51 for detection. After reaching the position of the connecting hoop 3, the third guide bar 54 is slid to the position to engage with one end of the first guide bar 51, and then the device moves to the position of the third guide bar 54 and continues to be guided and moved by the third guide bar 54, thereby ensuring that the detection device conducts a comprehensive detection of the welding position around the steel pipe.
