[0017] The present invention also provides a method for non-destructive inspection of pipelines, which is applied to the above-mentioned pipeline non-destructive inspection equipment and includes the following steps: S1: Rotate the first rotating block, and the first rotating block drives the threaded pillar to rotate. Since the transmission sleeve is threadedly connected to the threaded pillar, the rotation of the threaded pillar will push the transmission sleeve to move in the vertical direction. The transmission sleeve drives the first clamping plate to be adjusted, so as to fix the inspection pipe body main body of different sizes. Place the pipe body main body to be inspected on the first clamping plate, ensure that the pipeline is aligned with the first clamping plate. By rotating the second rotating block, drive the first screw rod to rotate. The first screw rod is threadedly connected to the threaded block and thus rotates inward and drives the first screw rod to move downward. The first screw rod pushes the second clamping plate to move downward, and cooperates with the first clamping plate to firmly clamp the pipeline. Then, start the transmission motor.

The transmission rod drives the arc-shaped support plate to rise, providing additional support for the pipeline and ensuring the stability of the pipeline during the inspection process; S2: Start the servo motor, and the servo motor drives the rotating rod to rotate. The transmission gear on the rotating rod rotates accordingly. Since the transmission gear is meshed with the transmission rack, the rotation of the transmission gear will drive the transmission rack to rotate axially around the transmission gear. The movement of the transmission rack drives the adjusting assembly and the clamping assembly on its top to move synchronously, thereby adjusting the rotation direction of the inspection pipe body main body, so that the non-destructive detector of the pipeline non-destructive inspection instrument can perform 360-degree inspection work on the inner wall of the inspection pipe body main body. After adjusting the position of the inspection pipe body main body, start the pipeline non-destructive inspection instrument, and perform non-destructive inspection on the inspection pipe body main body through the non-destructive detector. The inspection results will be displayed on the control screen for the operator to view and analyze.

[0018] Due to the adoption of the above technical solutions in the embodiments of the present invention, it has the following advantages: First, through the setting of the pipeline non-destructive inspection component, the clamping plate is used to fix and rotate the pipe material, so as to ensure the effect of efficient, all-round and convenient inspection of the pipe material, prevent the situation that the operator manually operates the rotation, which is time-consuming and laborious, improve the stability and durability of the pipeline non-destructive inspection component, reduce the maintenance requirements and extend the service life of the pipeline non-destructive inspection component, thereby improving the overall reliability of the pipeline non-destructive inspection component.

[0019] Second, through the setting of the pipeline non-destructive testing component, the pipeline can be efficiently detected, and the effect of being easy to control is achieved. Through the setting of the adjustment component, the position of the first clamping plate can be adjusted, and the movement range of the first clamping plate is limited. Through the setting of the clamping component, the pipeline can be quickly clamped, improving the clamping effect of the pipeline. Through the setting of the auxiliary support component, the pipeline can be supported, preventing the pipeline from being unstable due to single-point support and shaking during work. Through the setting of the connection component, the transmission gear plate and the transmission gear can be in a balanced connection state, enabling the transmission gear and the transmission gear plate to work efficiently. Through the setting of the guide rod, the second toothed plate can be limited, preventing the second toothed plate from following during movement. Through the setting of the limit component, the guide rod can be limited, and it has the effect of quick disassembly. Through the setting of the fixing plate, the servo motor can be supported, preventing the servo motor from being unstable due to single-point support.

[0036] The present invention also provides a pipeline non-destructive testing method, which is applied to the above-mentioned pipeline non-destructive testing equipment and includes the following steps: S1: Rotate the first rotating block 16. The first rotating block 16 drives the threaded pillar 15 to rotate. Since the transmission sleeve 17 is threadedly connected to the threaded pillar 15, the rotation of the threaded pillar 15 will push the transmission sleeve 17 to move in the vertical direction. The transmission sleeve 17 drives the first clamping plate 18 to be adjusted, so as to fix the test pipe body 11 of different sizes. Place the test pipe body 11 to be detected on the first clamping plate 18, ensure that the pipeline is aligned with the first clamping plate 18. By rotating the second rotating block 21, drive the first screw rod 22 to rotate. The first screw rod 22 rotates internally through threaded connection with the threaded block 23 and drives the first screw rod 22 to move downward. The first screw rod 22 pushes the second clamping plate 20 to move downward, and cooperates with the first clamping plate 18 to firmly clamp the pipeline. Then, start the transmission motor 25. The transmission motor 25 drives the first gear 26 to rotate through the output end. The first gear 26 drives the second gear 27 to rotate through meshing. The second gear 27 drives the second screw rod 28 to rotate. The second screw rod 28 drives the transmission rod 29 to move upward on the surface of the second screw rod 28 through threaded connection. The transmission rod 29 stably moves upward on the surface of the sliding rod 39 through the moving block 38. The transmission rod 29 drives the arc-shaped support plate 30 to rise, providing additional support for the pipeline to ensure the stability of the pipeline during the detection process; S2: Start the servo motor 4. The servo motor 4 drives the rotating rod 5 to rotate. The transmission gear 6 on the rotating rod 5 rotates accordingly. Since the transmission gear 6 meshes with the transmission tooth plate 7, the rotation of the transmission gear 6 will drive the transmission tooth plate 7 to rotate axially around the transmission gear 6. The movement of the transmission tooth plate 7 drives the adjustment assembly 8 and the clamping assembly 9 on its top to move synchronously, thereby adjusting the rotation direction of the test pipe body 11, so that the non-destructive detector 14 of the pipeline non-destructive detector 12 can perform 360-degree detection on the inner wall of the test pipe body 11. After adjusting the position of the test pipe body 11, start the pipeline non-destructive detector 12, and perform non-destructive detection on the test pipe body 11 through the non-destructive detector 14. The detection results will be displayed on the control screen 13 for the operator to view and analyze.

[0037] Through the setting of the pipeline non-destructive detection component 1, the pipeline can be efficiently detected, and the effect of being easy to control is achieved. Through the setting of the adjustment component 8, the position of the first clamping plate 18 can be adjusted, and the moving range of the first clamping plate 18 is limited. Through the setting of the clamping component 9, the pipeline can be quickly clamped, improving the clamping effect of the pipeline. Through the setting of the auxiliary support component 10, the pipeline can be assisted in supporting, preventing the pipeline from being unstable due to single-point support and shaking during work. Through the setting of the connection component, the transmission gear plate 7 and the transmission gear 6 can be in a balanced connection state, enabling the transmission gear 6 and the transmission gear plate 7 to work efficiently. Through the setting of the guide rod 34, the second gear plate can be limited, preventing the second gear plate from following during movement. Through the setting of the limiting component, the guide rod 34 can be limited, and it has the effect of quick disassembly. Through the setting of the fixing plate 37, the servo motor 4 can be assisted in supporting, preventing the servo motor 4 from being unstable due to single-point support. Through the setting of the moving block 38 and the sliding rod 39, the transmission rod 29 can be limited, improving the stability of the transmission rod 29.

[0038] When the present invention is in operation: Rotate the first rotating block 16, and the first rotating block 16 drives the threaded pillar 15 to rotate. Since the transmission sleeve 17 is threadedly connected to the threaded pillar 15, the rotation of the threaded pillar 15 will push the transmission sleeve 17 to move in the vertical direction. The transmission sleeve 17 drives the first clamping plate 18 to be adjusted, so as to fix the inspection tube body main body 11 of different sizes. Place the inspection tube body main body 11 to be inspected on the first clamping plate 18, and ensure that the pipeline is aligned with the first clamping plate 18. By rotating the second rotating block 21, drive the first screw rod 22 to rotate. The first screw rod 22 rotates inward through the threaded connection with the threaded block 23 and drives the first screw rod 22 to move downward. The first screw rod 22 pushes the second clamping plate 20 to move downward, and cooperates with the first clamping plate 18 to firmly clamp the pipeline. Then, start the transmission motor 25. The transmission motor 25 drives the first gear 26 to rotate through the output end. The first gear 26 drives the second gear 27 to rotate through meshing. The second gear 27 drives the second screw rod 28 to rotate. The second screw rod 28 drives the transmission rod 29 to move upward on the surface of the second screw rod 28 through the threaded connection. The transmission rod 29 stably moves upward on the surface of the slide rod 39 through the moving block 38. The transmission rod 29 drives the arc-shaped support plate 30 to rise, providing additional support for the pipeline and ensuring the stability of the pipeline during the inspection process. Start the servo motor 4. The servo motor 4 drives the rotating rod 5 to rotate, and the transmission gear 6 on the rotating rod 5 rotates accordingly. Since the transmission gear 6 meshes with the transmission tooth plate 7, the rotation of the transmission gear 6 will drive the transmission tooth plate 7 to rotate axially around the transmission gear 6. The movement of the transmission tooth plate 7 drives the adjustment assembly 8 and the clamping assembly 9 at its top to move synchronously, thereby adjusting the rotation direction of the inspection tube body main body 11, so that the non-destructive detector 14 of the pipeline non-destructive detector 12 can perform 360-degree inspection on the inner wall of the inspection tube body main body 11. After adjusting the position of the inspection tube body main body 11, start the pipeline non-destructive detector 12, and perform non-destructive inspection on the inspection tube body main body 11 through the non-destructive detector 14. The inspection results will be displayed on the control screen 13 for the operator to view and analyze.

A non-destructive testing method for pipelines, applied to the non-destructive testing equipment for pipelines described in claim 9, characterized in that: Comprising the following steps: S1: Rotate the first rotating block (16). The first rotating block (16) drives the threaded pillar (15) to rotate. Since the transmission sleeve (17) is threadedly connected to the threaded pillar (15), the rotation of the threaded pillar (15) will push the transmission sleeve (17) to move in the vertical direction. The transmission sleeve (17) drives the first clamping plate (18) to be adjusted, and different-sized test tube bodies (11) can be fixed. Place the test tube body (11) to be detected on the first clamping plate (18), ensure that the pipeline is aligned with the first clamping plate (18). By rotating the second rotating block (21), drive the first screw rod (22) to rotate. The first screw rod (22) is threadedly connected to the threaded block (23) and thus rotates internally and drives the first screw rod (22) to move downward. The first screw rod (22) pushes the second clamping plate (20) to move downward and cooperate with the first clamping plate (18) to firmly clamp the pipeline. Then, start the transmission motor (25). The transmission motor (25) drives the first gear (26) to rotate through the output end. The first gear (26) drives the second gear (27) to rotate through meshing. The second gear (27) drives the second screw rod (28) to rotate. The second screw rod (28) is threadedly connected to the transmission rod (29) and drives the transmission rod (29) to move upward on the surface of the second screw rod (28). The transmission rod (29) stably moves upward on the surface of the sliding rod (39) through the moving block (38). The transmission rod (29) drives the arc-shaped support plate (30) to rise, providing additional support for the pipeline and ensuring the stability of the pipeline during the detection process; S2: Start the servo motor (4). The servo motor (4) drives the rotating rod (5) to rotate, and the transmission gear (6) on the rotating rod (5) rotates accordingly. Since the transmission gear (6) meshes with the transmission tooth plate (7), the rotation of the transmission gear (6) will drive the transmission tooth plate (7) to rotate axially around the transmission gear (6). The movement of the transmission tooth plate (7) drives the adjustment component (8) and the clamping component (9) on its top to move synchronously, thereby adjusting the rotation direction of the inspection tube body main body (11), so that the non-destructive detector (14) of the pipeline non-destructive detector (12) can perform 360-degree inspection on the inner wall of the inspection tube body main body (11). After adjusting the position of the inspection tube body main body (11), start the pipeline non-destructive detector (12), and perform non-destructive inspection on the inspection tube body main body (11) through the non-destructive detector (14). The inspection results will be displayed on the control screen (13) for the operator to view and analyze.
