DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 and Figure 2 It can be seen that the utility model provides a technical solution: a seamless steel pipe thickness ultrasonic detection and adjustment device, comprising: a placement rack 1, a placement seat 2, a steel pipe body 3, a slide rail rack 4, a moving seat 5, a detection box 6 and a connecting block 7;

[0020] A placement seat 2 is installed on the surface of the placement rack 1, a steel pipe body 3 is placed on the inner wall of the placement seat 2, a slide rail frame 4 is installed on the top of the placement rack 1, a moving seat 5 is movably connected to the bottom of the slide rail frame 4, and a detection box 6 is arranged at the bottom of the moving seat 5;

[0021] A connecting block 7 is installed at the bottom of the moving seat 5, and a limiting block 8 is connected to the outer side of the connecting block 7. A sliding rod 9 is connected to the top of the detection box 6, and a slider 10 is installed on the outer side of the sliding rod 9. A rack 11 is connected to the end of the slider 10. A fixed block 12 is installed at the bottom of the moving seat 5, and a motor 13 is installed at the front of the fixed block 12. A gear 14 is welded to the output end of the motor 13, and a meshing structure is formed between the gear 14 and the rack 11, a sliding structure is formed between the limiting block 8 and the rack 11, and a sliding structure is formed between the sliding rod 9 and the connecting block 7.

[0022] During specific implementation, the ultrasonic detection equipment can detect defects such as thickness, cracks, pits, etc. of the steel pipe body 3. Usually, the distance between the detection box 6 and the steel pipe body 3 is fixed, which means that the detection box 6 can only detect the steel pipe body 3 of a specified diameter, which is less practical. For this reason, steel pipe bodies 3 of different diameters can be placed on the placement seat 2, and the motor 13 can be started. When the motor 13 is started, the gear 14 can be driven to rotate through the output end. When the gear 14 rotates, the rack 11 can be driven to engage and move. When the rack 11 moves, the slider 10 can be driven to move. When the slider 10 moves, the slide bar 9 can be driven to move. When the slide bar 9 moves, the detection box 6 can be driven to move. When the rack 11 moves, it can slide with the limit block 8. When the bottom of the detection box 6 moves to the surface of the steel pipe body 3, the motor 13 can be turned off. At this time, the detection box 6 can detect the steel pipe body 3.

[0023] See also Figure 1 and Figure 2 It can be seen that by adjusting the distance between the detection box 6 and the steel pipe body 3, the detection box 6 can detect the steel pipe bodies 3 of different diameters, thereby improving the practicability of the ultrasonic detection equipment.

[0024] See also Figure 1 and Figure 3 It can be seen that a slide groove 15 is provided on the surface of the placement rack 1, and a mounting block 16 is welded on the side of the surface of the placement rack 1 close to the slide groove 15. The internal thread of the mounting block 16 is connected to a knob 17. The interior of the slide groove 15 is movably connected to a connecting plate 18. A mounting seat 19 is welded to the top of the connecting plate 18. A connecting rod 20 is welded to the inside of the mounting seat 19. A pulley 21 is movably connected to the outer side of the connecting rod 20. The slide groove 15 forms a sliding structure between the connecting plate 18 and the placement rack 1.

[0025] During specific implementation, the placement seat 2 on the ultrasonic detection equipment is used to place the steel pipe body 3, and it is rather difficult for personnel to manually push the steel pipe body 3 to move. For this reason, the mounting seat 19 can be pushed. When the mounting seat 19 moves, the connecting plate 18 can be driven to move. When the connecting plate 18 moves, it can slide to the bottom of the steel pipe body 3 through the slide groove 15. At this time, the knob 17 can be rotated. When the knob 17 is rotated, it can be threadedly fixed with the connecting plate 18. When the bottom of the steel pipe body 3 is pushed to the top of the pulley 21, the steel pipe body 3 can drive the pulley 21 to rotate during the movement. When the pulley 21 rotates, it can be rotated through the connecting rod 20. At this time, the pulley 21 can assist the steel pipe body 3 to move its position.

[0026] See also Figure 1 and Figure 3It can be seen that the pulley 21 can reduce the force required by personnel to push the steel pipe body 3 to move, so that the steel pipe body 3 can move more smoothly and quickly.

[0027] In summary, when using the seamless steel pipe thickness ultrasonic detection and adjustment device, the steel pipe body 3 is placed on the placement seat 2. At this time, the detection box 6 can detect the steel pipe body 3. The detection box 6 can comprehensively detect the steel pipe body 3 by the propagation time, distance and reflected waveform of the ultrasonic wave on the steel pipe body 3 to prevent unqualified products from flowing into the market. The seamless steel pipe thickness ultrasonic detection equipment is a prior art and will not be described in detail here. When the bottom of the detection box 6 moves to the surface of the steel pipe body 3, the motor 13 can be turned off. At this time, the detection box 6 can detect the steel pipe body. The detection box 6 can detect the steel pipe body 3, and by adjusting the distance between the detection box 6 and the steel pipe body 3, the detection box 6 can detect the steel pipe bodies 3 of different diameters, thereby improving the practicality of the ultrasonic detection equipment. When the pulley 21 rotates, it can be rotated by the connecting rod 20. At this time, the pulley 21 can assist the steel pipe body 3 to move its position. The pulley 21 can reduce the force of personnel when pushing the steel pipe body 3 to move, so that the steel pipe body 3 is smoother and faster during the movement.
