[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: an ultrasonic flaw detection device for pipe flaw detection, a mounting frame 1, and a display screen 11 disposed in the inner cavity of the mounting frame 1;

[0027] Adjustment component 2 includes a gear 21 disposed on the side of display screen 11, a wheel 22 meshing with the bottom of the gear 21, a fixing block 23 rotatably connected to the side of the wheel 22, a connecting rod 24 fixedly connected to the side of the fixing block 23, and a mounting plate 26 disposed at the end of the connecting rod 24 away from the fixing block 23.

[0028] Auxiliary component 3 includes a fixing plate 34 mounted on the side of mounting plate 26. A flexible pad 31 is provided on the side of the fixing plate 34. A connecting plate 25 is rotatably connected to the top of connecting rod 24. The end of connecting plate 25 away from connecting rod 24 is fixedly connected to the side of mounting plate 26. A fixing rod 27 is fixedly connected to the end of mounting plate 26 away from connecting plate 25. A support frame 28 is rotatably connected to the inner wall of wheel 22. The top of support frame 28 is rotatably connected to the bottom of fixing rod 27. A groove 29 is provided on the side of support frame 28. A heat dissipation groove 210 is provided on the top of mounting plate 26. A drive motor is provided on the side of gear 21 to provide power for the overall operation of adjustment component 2. The rotation direction of wheel 22 can be controlled by adjusting the rotation direction of the motor output shaft. When wheel 22 rotates clockwise, the fixing block 23 and connecting rod 24 cooperate to drive connecting plate 25 and mounting plate 26 along the fixing rod. The outer surface of the mounting plate 27 rotates counterclockwise, thereby driving the probe head located on the side of the mounting plate 26 to move closer to the wheel 22. When the mounting plate 26 moves to a certain position, its position tilts, causing the side of the mounting plate 26 to move away from the outer surface of the pipe. By setting the fixing rod 27, the movement trajectory of the mounting plate 26 can be limited, ensuring that one side of the mounting plate 26 contacts the outer surface of the pipe first, quickly adapting to pipes with larger diameters. Similarly, when it is necessary to detect pipes with smaller diameters, by changing the rotation direction of the output shaft of the drive motor, the wheel 22 can be rotated counterclockwise. Through the cooperation of the fixing block 23, connecting rod 24 and connecting plate 25, the mounting plate 26 can be rotated counterclockwise along the outer surface of the fixing rod 27, thereby driving the probe head closer to the outer surface of the pipe, effectively improving the adaptability of the detection equipment and increasing work efficiency.

[0029] Furthermore, such as Figure 2 - Figure 4 As shown: An elastic joint 33 is fixedly connected to the inner cavity of the fixed plate 34, and a roller 32 is fixedly connected to the side of the elastic joint 33. The fixed plate 34 installed on the side of the mounting plate 26 can provide support for the flexible pad 31, the roller 32 and the elastic joint 33. By setting the flexible pad 31, the probe can be assisted in working and the expansion of the probe and the pipe can be avoided. After the mounting plate 26 is adjusted to fit against the outer surface of the pipe, the side of the roller 32 contacts the outer surface of the pipe, which can assist the probe to move smoothly. By setting the elastic joint 33, the movement stability of the roller 32 can be improved.

[0030] like Figure 1-4 As shown:

[0031] In use: First, place the building pipe on top of the external support frame 28. Then, mount the wheel 22 on the outer surface of the pipe. Powered by an external power source, the display screen 11 and the drive motor located on the side of the gear 21 are activated. When detecting pipes with larger diameters, starting the motor causes its output shaft to rotate clockwise, which in turn drives the wheel 22 to rotate clockwise via the gear 21. As the wheel 22 moves, the fixing block 23 and the connecting rod 24 work together to drive the connecting plate 25 and the mounting plate 26 to rotate clockwise along the outer surface of the fixing rod 27, thereby causing the mounting plate 26 to shift position. When the mounting plate 26 moves to a certain position, the sides of the roller 32 and the flexible pad 31 contact the outer surface of the pipe, thus enabling detection. Similarly, when it is necessary to detect pipes with smaller diameters, by adjusting the rotation direction of the output shaft of the drive motor, the wheel 22 can drive the fixed block 23 to move counterclockwise. In turn, the fixed block 23, the connecting rod 24, and the connecting plate 25 can drive the mounting plate 26 to move counterclockwise along the outer surface of the fixed rod 27. When the mounting plate 26 moves to a certain position, the overall position of the mounting plate 26 tilts, thus contacting the outer surface of the pipe, effectively improving overall adaptability.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
