A mounting seat 16 is installed inside the detection housing 21. A detection plate 14 is installed on one side of the mounting seat 16. An ultrasonic detection probe 13 is arranged inside one end of the detection plate 14.

[0032] One end of the detection housing 21 is provided with a moving seat 23. An installation electric rod 24 is fixedly installed inside the moving seat 23. A moving frame 25 is slidably installed on one side of the moving seat 23. A moving wheel 27 is rotatably installed inside the moving frame 25. One end of the moving frame 25 is provided with a moving motor 26. The output shaft of the moving motor 26 is fixedly connected to the moving wheel 27. The cross-sectional shapes of the moving strap 11 and the guide rail strap 12 are both set to U-shaped, and the moving wheel 27 is located between the moving strap 11 and the guide rail strap 12. Reinforcing steel cable straps 112 are provided inside both the moving strap 11 and the guide rail strap 12. Anti-slip teeth 111 are provided on one side of both the moving strap 11 and the moving wheel 27. An anti-wear roller 121 is provided inside the guide rail strap 12. When in use, it is ensured that the moving wheel 27 moves more stably inside the moving strap 11 and the guide rail strap 12. The moving motor 26 drives the moving wheel 27 to rotate, and with the engagement of the anti-slip teeth 111 and the rotation of the anti-wear roller 121, the moving wheel 27 rotates and moves between the moving strap 11 and the guide rail strap 12, so that the detection housing 21 and the ultrasonic detection probe 13 move along the guide rail strap 12; the cross-sectional shape of the moving frame 25 is set to a double-layer dovetail shape. A dovetail groove is provided at a position on one side of the moving seat 23 corresponding to the moving frame 25. The moving frame 25 slides in the dovetail groove. When in use, it is ensured that the moving frame 25 and the moving wheel 27 are pushed to move more stably by the installation electric rod 24;

[0033] The winding mechanism 5 includes an installation baffle 54 fixed inside the storage seat 1 and a winding roller 56 rotatably installed inside the storage seat 1. Winding spiral sheets 55 are provided at both ends of the winding roller 56, and the spiral directions of the winding spiral sheets 55 at both ends are opposite. The middle part of the winding roller 56 is located between the installation baffles 54, and a transmission worm gear 53 is installed in the middle part of the winding roller 56. A transmission worm 52 is engaged with one side of the transmission worm gear 53. One end of the transmission worm 52 passes through the storage seat 1 and is fixedly installed with a winding handwheel 51;

[0034] Two winding rollers 56 are installed inside the storage seat 1. The moving strap 11 and the guide rail strap 12 are respectively wound on the two winding rollers 56.

[0035] As can be seen from the above description, the present invention has the following beneficial effects: When in use, the moving strap 11 and the guide rail strap 12 are quickly buckled on the steel pipe. The winding mechanism 5 is used to adjust the tightness of the moving strap 11 and the guide rail strap 12. The detection seat 2 walks on the storage seat 1 and the guide rail strap 12. The ultrasonic detection probe 13 inside the detection seat 2 fully detects the internal defects of the steel pipe. Compared with the traditional hand-held probe detection, the detection device of the present invention is more stable during detection movement and the detection accuracy is significantly improved when in use. The collected data can more accurately reflect the weld quality.

[0036] Embodiment 2: Please refer to Figures 1 to 9 As shown, on the basis of Embodiment 1, 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 inside the fixed seat 71. One end of the sliding column 72 presses on the buffer spring 73. A hanging hole is provided at one end of the sliding column 72 for connecting the fixed hook 18. The generated vibration is buffered by pressing the sliding column 72 on the buffer spring 73. An installation clamping plate 74 is installed outside the buffer spring 73. Damping sliding seats 75 are fixedly installed at both ends of the installation clamping plate 74. The installation clamping plate 74 clamps the buffer spring 73 and is fixed through the damping sliding seats 75. The damping sliding seats 75 at both ends of the installation clamping plate 74 respectively fit and slide on the inner wall of the fixed seat 71 and the surface of the sliding column 72. A damping sliding plate 76 is provided inside one end of the sliding column 72. A damping sliding groove 77 is provided on the inner wall of the fixed seat 71. The damping sliding plate 76 is slidably installed inside the damping sliding groove 77. The friction of the damping sliding seat 75 sliding in the fixed seat 71 and the damping sliding plate 76 sliding in the damping sliding groove 77 provides damping, thereby strengthening the shock absorption and ensuring more stable movement.

[0037] With the above technical solution of the buffer seat 7, the buffer seat 7 is used to connect the fixed plate 17 and the storage seat 1, 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.

[0038] Working principle and usage process of the present invention: When in use, rotate the winding handwheel 51 to drive the driving worm 52 to rotate. The driving worm 52 drives the driving worm gear 53 and the winding roller 56 to rotate, so as to release the moving hoop belt 11 and the guide rail hoop belt 12. First, put the guide rail hoop belt 12 on the steel pipe and hang it on the sliding column 72 through the fixing plate 17 and the fixing hook 18. Then, rotate the driving worm 52 in the reverse direction to drive the winding roller 56 to wind and tighten the guide rail hoop belt 12 on the steel pipe for fixation. When tightening, the sliding column 72 slides and presses on the buffer spring 73. Then, install the moving hoop belt 11 on the buffer seat 7 through the fixing plate 17 and the fixing hook 18, install the detection seat 2 on the outside of the moving hoop belt 11. According to the positions of the moving hoop belt 11 and the guide rail hoop belt 12, then install the moving hoop belt 11 in the moving seat 23. Push the moving frame 25 and the moving wheel 27 to move by installing the electric rod 24, so that the moving hoop belt 11 is limited in the moving seat 23. Then, tighten the moving hoop belt 11 through the winding mechanism 5, so that the moving hoop belt 11 presses on the moving wheel 27, so that the moving wheel 27 is located between the moving hoop belt 11 and the guide rail hoop belt 12. Install the detection seat 2 on the moving hoop belt 11 and the guide rail hoop belt 12. Drive the moving wheel 27 to rotate through the moving motor 26, and cooperate with the engagement of the anti-slip teeth 111 and the rotation of the anti-wear roller 121, so that the moving wheel 27 rotates and moves between the moving hoop belt 11 and the guide rail hoop belt 12, so that the detection housing 21 and the ultrasonic detection probe 13 move along the guide rail hoop belt 12, and the ultrasonic detection probe 13 detects the steel pipe weld. During detection, adjust the moving hoop belt 11 and the guide rail hoop belt 12 multiple times as needed, so that a complete circle of the steel pipe weld can be detected. And multiple detections ensure the accuracy of detection, and can better locate the weld defects. The vibration generated during movement is buffered by the sliding column 72 pressing on the buffer spring 73. At the same time, the damping sliding seat 75 slides on the fixed seat 71 and the sliding column 72, and the friction of the damping sliding plate 76 sliding in the damping chute 77 provides damping, so as to strengthen the shock absorption and ensure more stable movement. After use, remove the detection seat 2, and wind the moving hoop belt 11 and the guide rail hoop belt 12 on the storage seat 1, which is more convenient for storage and carrying during use.
