[0019] This disclosure provides a pipeline flaw detection device, comprising a support platform, a first support, a first rotating shaft, a first support wheel, a second support, a second rotating shaft, a second support wheel, a drive component, and a detection component. The support platform is used to abut against the ground or a tabletop, thereby supporting the entire device. The first support is installed on the top surface of the support platform to support the rotatable first rotating shaft. The first rotating shaft is rotatably mounted on the first support along the length of the support platform and located on both sides of the first support along the width of the support platform; both first rotating shafts can rotate relative to the first support. First support wheels are respectively installed on both sides of the first rotating shaft, each supporting one end of the pipeline. The second support is installed on the top surface of the support platform to support the rotatable second rotating shaft. The second support and the first support are located on both sides of the support platform along the length of the support platform.

[0038] Combination Figures 1 to 5As shown, this embodiment of the present disclosure provides a pipe flaw detection device, including a support platform 1, a first support 2, a first rotating shaft 3, a first support wheel 4, a second support 5, a second rotating shaft 6, a second support wheel 7, a driving component, and a detection component. The support platform 1 is used to abut against the ground or a tabletop, thereby supporting the entire device. The first support 2 is installed on the top surface of the support platform 1 to support the rotatable first rotating shaft 3. The first rotating shaft 3 is rotatably installed on the first support 2 along the length direction of the support platform 1, and located on both sides of the first support 2 along the width direction of the support platform 1. Both sides of the first rotating shaft 3 can rotate relative to the first support 2. The first support wheel 4 is respectively installed on both sides of the first rotating shaft 3, each supporting one end of the pipe. The second support 5 is installed on the top surface of the support platform 1 to support the rotatable second rotating shaft 6. Along the length direction of the support platform 1, the second support 5 and the first support 2 are located on both sides of the support platform 1. The second rotating shaft 6 is rotatably mounted on the second support 5 along the length of the support platform 1 and located on both sides of the second support 5 along the width of the support platform 1. Both second rotating shafts 6 can rotate relative to the second support 5. Second support wheels 7 are respectively mounted on the two second rotating shafts 6 and are used to support the other end of the pipe. A driving component is installed between the support platform 1, the first support 2, the second support 5, the two first rotating shafts 3, and the two second rotating shafts 6 to provide driving force and drive the two first rotating shafts 3 and the two second rotating shafts 6 to rotate synchronously. A detection component is installed on the top surface of the support platform 1 to perform flaw detection on the pipe placed on the two first support wheels 4 and the two second support wheels 7.

[0039] This embodiment of the pipe flaw detection device allows for free rotation of the first support wheels 4 on both sides, as the first rotating shafts 3 on both sides can rotate relative to the first support 2. Similarly, the second rotating shafts 6 on both sides can rotate relative to the second support 5, allowing the second support wheels 7 on both sides to rotate freely. Therefore, when a pipe is placed on the first support wheels 4 and the second support wheels 7, they rotate along with the pipe, converting sliding friction into rolling friction to facilitate pipe rotation. Furthermore, under the drive of the driving component, the first rotating shafts 3 and the second rotating shafts 6 rotate synchronously, thereby driving the first support wheels 4 and the second support wheels 7 to rotate synchronously, achieving automatic pipe rotation. Then, in conjunction with the detection component, the entire surface of the pipe can be inspected, facilitating flaw detection across the entire pipe surface.

[0040] Optionally, combined Figure 1 , Figure 2 and Figure 5As shown, the driving component includes a third rotating shaft 8, a first driving synchronous belt gear, a first driven synchronous belt gear, and a first synchronous toothed belt 9. The third rotating shaft 8 is rotatably mounted on the first support 2 and the second support 5 along the length of the support platform 1, and can rotate relative to the first support 2 and the second support 5. The first driving synchronous belt gear is mounted on the third rotating shaft 8 and rotates under the drive of the third rotating shaft 8. The first driven synchronous belt gears are respectively mounted on the two sides of the first rotating shaft 3, and are used to drive the rotation of the two sides of the first rotating shaft 3. The first synchronous toothed belt 9 is fitted between the first driving synchronous belt gear and the two sides of the first driven synchronous belt gear, and is used to transmit driving force. The third rotating shaft 8 can be controlled to rotate, so that the two first rotating shafts 3 rotate synchronously.

[0041] In this embodiment, the third rotating shaft 8 rotates under the drive of an external force, which in turn drives the first active synchronous pulley to rotate. Through the first synchronous toothed belt 9, it drives the first driven synchronous pulleys on both sides to rotate. This, in turn, drives the first rotating shafts 3 on both sides to rotate synchronously, ultimately achieving the function of synchronous rotation of the first support wheels 4 on both sides.

[0042] Optionally, combined Figure 1 、. Figure 3 , Figure 4 and Figure 5 As shown, the driving component also includes a second driving synchronous belt gear, a second driven synchronous belt gear, and a second synchronous toothed belt 10. The second driving synchronous belt gear is mounted on the third rotating shaft 8 and rotates under the drive of the third rotating shaft 8. The second driven synchronous belt gears are respectively mounted on the two second rotating shafts 6 on both sides, and are used to drive the two second rotating shafts 6 to rotate respectively. The second synchronous toothed belt 10 is fitted between the second driving synchronous belt gear and the two second driven synchronous belt gears on both sides, and is used to transmit driving force. Among them, the third rotating shaft 8 can be controlled to rotate so that the two first rotating shafts 3 and the two second rotating shafts 6 on both sides rotate synchronously.

[0043] In this embodiment, the third rotating shaft 8 rotates under the drive of an external force, which in turn drives the first and second active synchronous pulleys to rotate. Through the first and second synchronous toothed belts 9 and 10, the first and second driven synchronous pulleys on both sides can rotate. This, in turn, drives the first rotating shafts 3 and the second rotating shafts on both sides to rotate synchronously, ultimately achieving the function of synchronous rotation of the first support wheels 4 and the second support wheels 7 on both sides.

[0044] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, the drive unit also includes a motor 11 and a coupling 12. The motor 11 is mounted on the top surface of the support platform 1 to provide driving force. The coupling 12 is mounted between the rotating end of the motor 11 and the third rotating shaft 8 to transmit driving force.

[0045] In this embodiment, the control motor 11 operates, and through the coupling 12, it can drive the third rotating shaft 8 to rotate, ultimately realizing the function of automatic synchronous rotation of the first support wheel 4 on both sides and the second support wheel 7 on both sides.

[0046] Optionally, combined Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the drive component also includes a first mounted bearing 13. The first mounted bearing 13 is fitted onto the third rotating shaft 8 and is mounted on the first support 2 and the second support 5 respectively.

[0047] In this embodiment of the present disclosure, the first bearing 13 is used to reduce the friction between the third shaft 8 and the first support 2 and the second support 5, and to improve the accuracy of the third shaft 8 when rotating relative to the first support 2 and the second support 5.

[0048] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, the detector includes a first linear slide 14, a first movable plate 15, a second linear slide 16, a second movable plate 17, an electric push rod 18, a third movable plate 19, and an X-ray generator 20. The first linear slide 14 is mounted on the top surface of the support platform 1 along its length, providing driving force to move along the length of the support platform 1. The first movable plate 15 is mounted on the movable end of the first linear slide 14 and moves along the length of the support platform 1 under the drive of the first linear slide 14. The second linear slide 16 is mounted on the first movable plate 15 along the height of the support platform 1, providing driving force to move along the height of the support platform 1. The second movable plate 17 is mounted on the movable end of the second linear slide 16 and moves along the height of the support platform 1 under the drive of the second linear slide 16. An electric actuator 18 is mounted on the second movable plate 17 along the width direction of the support platform 1. The moving end of the electric actuator 18 faces the pipes placed on the first support wheels 4 and the second support wheels 7 on both sides, providing driving force to enable movement along the width direction of the support platform 1. A third movable plate 19 is mounted on the moving end of the electric actuator 18 and moves along the width direction of the support platform 1 under the drive of the electric actuator 18. An X-ray generating device 20 is mounted on the third movable plate 19 and faces the pipes placed on the first support wheels 4 and the second support wheels 7 on both sides, generating X-rays for flaw detection of the pipes.

[0049] In this embodiment, controlling the first linear slide 14 moves the first moving plate 15 along the length of the support platform 1, ultimately moving the X-ray generator 20 along the length of the support platform 1, allowing the X-ray generator 20 to move along the length of the pipe. Controlling the second linear slide 16 moves the second moving plate 17 along the height of the support platform 1, ultimately moving the X-ray generator 20 along the height of the support platform 1, ensuring that the X-ray generator 20 is aligned with the pipe axis even for pipes of different diameters. Controlling the electric push rod 18 moves the third moving plate 19 along the width of the support platform 1 to adjust the distance between the X-ray generator 20 and the pipe. Working in conjunction with the motor 11, the entire pipe flaw detection process can be completed. Furthermore, since the X-ray generator 20 is located to the sides of the first support wheels 4 and the second support wheels 7, it is convenient to place the pipe directly on the first support wheels 4 and the second support wheels 7.

[0050] Optionally, the detector also includes reinforcing plates. The reinforcing plates are respectively installed at the bends of the first movable plate 15, the second movable plate 17, and the third movable plate 19.

[0053] In this embodiment, the second bearings 21 on both sides are used to reduce the friction between the first rotating shafts 3 on both sides and the first support 2, and to improve the accuracy of the first rotating shafts 3 on both sides when rotating relative to the first support 2.

[0054] Optionally, combined Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, it also includes a third mounted bearing 22. The third mounted bearing 22 is respectively fitted onto the second rotating shafts 6 on both sides, and is mounted on the second support 5.
