[0021] Example 2: Please refer to Figures 1 to 9 As shown, on the basis of the first embodiment, the present invention provides a technical solution: the buffer seat 7 includes a fixed seat 71 fixed on the storage seat 1 and a sliding column 72 slidably installed in the fixed seat 71, a buffer spring 73 is installed on the inner side of the fixed seat 71, one end of the sliding column 72 is pressed on the buffer spring 73, and one end of the sliding column 72 is provided with a hanging hole, which is used to connect the fixed hook 18, and the generated vibration is pressed on the buffer spring 73 by the sliding column 72 for buffering; a mounting splint 74 is installed on the outer side of the buffer spring 73, and damping sliding splints are fixedly installed at both ends of the mounting splint 74 The seat 75, the mounting clamp 74 is clamped on the buffer spring 73 and fixed by the damping slide 75, the damping slides 75 at both ends of the mounting clamp 74 slide on the inner wall of the fixed seat 71 and the surface of the sliding column 72 respectively, a damping slide plate 76 is provided on the inner side of one end of the sliding column 72, and a damping groove 77 is provided on the inner wall of the fixed seat 71. The damping slide plate 76 is slidably installed on the inner side of the damping groove 77. The friction between the damping slide 75 sliding in the fixed seat 71 and the damping slide plate 76 sliding in the damping groove 77 provides damping, thereby enhancing shock absorption and ensuring more stable movement.

[0022] The buffer seat 7 of the above technical solution is adopted to connect the fixing plate 17 and the storage seat 1 through the buffer seat 7, and the vibration generated by the movement of the detection seat 2 during use is buffered, thereby reducing the phenomenon of fatigue damage at the connection due to vibration.

[0023] The working principle and use process of the present invention are as follows: when in use, the winding hand wheel 51 is rotated to drive the transmission worm 52 to rotate, and the transmission worm 52 drives the transmission worm wheel 53 and the winding roller 56 to rotate, thereby releasing the mobile band 11 and the guide rail band 12, firstly, the guide rail band 12 is put on the steel pipe, and hung on the sliding column 72 through the fixing plate 17 and the fixing hook 18, and then the transmission worm 52 is rotated in the opposite direction to drive the winding roller 56 to wind up and tighten the guide rail band 12 on the steel pipe, and when tightening, the sliding column 72 slides and presses on the buffer spring 73, and then the mobile band 11 and the guide rail band 12 are released. The moving band 11 is installed on the buffer seat 7 through the fixing plate 17 and the fixing hook 18, and the detection seat 2 is installed on the outside of the moving band 11. According to the position of the moving band 11 and the guide rail band 12, the moving band 11 is then installed in the moving seat 23, and the moving frame 25 and the moving wheel 27 are pushed to move by installing the electric rod 24, so that the moving band 11 is limited in the moving seat 23, and then the moving band 11 is tightened by the winding mechanism 5, so that the moving band 11 is pressed on the moving wheel 27, so that the moving wheel 27 is located between the moving band 11 and the guide rail band The detection seat 2 is installed on the moving hoop 11 and the guide rail hoop 12, and the moving wheel 27 is driven to rotate by the moving motor 26, and the anti-slip teeth 111 are engaged and the anti-wear roller 121 is rotated to make the moving wheel 27 rotate and move between the moving hoop 11 and the guide rail hoop 12, so that the detection housing 21 and the ultrasonic detection probe 13 move along the guide rail hoop 12, so that the ultrasonic detection probe 13 detects the steel pipe weld. During the detection, the moving hoop 11 and the guide rail hoop 12 are adjusted multiple times as needed, so that the steel pipe weld can be inspected. The pipe weld is fully inspected in one circle, and multiple inspections are performed to ensure the accuracy of the inspection, so that the weld defects can be better located. The vibration generated during movement is buffered by the sliding column 72 pressing on the buffer spring 73. At the same time, the friction between the damping slide 75 sliding in the fixed seat 71 and the sliding column 72 and the damping slide plate 76 sliding in the damping slide groove 77 provides damping, thereby enhancing shock absorption and ensuring more stable movement. After use, the inspection seat 2 is removed, and the moving hoop 11 and the guide rail hoop 12 are rolled up in the storage seat 1, which is more convenient to store and carry when in use.
