Description

Technical Field

[0001] This utility model belongs to the field of pipeline flaw detection technology, specifically a retractable tracked pipeline magnetic particle flaw detector. Background Technology

[0002] Magnetic particle testing utilizes the fact that when ferromagnetic materials are magnetized, the discontinuities cause local distortion of the magnetic field lines on and near the workpiece surface, resulting in a leakage magnetic field that attracts magnetic powder applied to the workpiece surface, forming magnetic marks visible to the naked eye under suitable lighting, thus revealing the location, shape, and size of the discontinuities.

[0003] Meanwhile, a pipeline magnetization magnetic particle flaw detector with announcement number CN218036566U is disclosed. It includes a frame and a sprayer installed on the frame. A connecting copper busbar is installed on the frame and is located above the sprayer. A magnetization coil is installed on the frame and is located below the sprayer. The magnetization coil is made by winding a whole cable and both ends of the cable are fixedly connected to the connecting copper busbar.

[0004] The aforementioned magnetic particle flaw detector for pipeline magnetization is designed to be applicable only to pipelines with small diameters, limiting its application range. Furthermore, its heavy weight makes it difficult to carry and inconvenient to use.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model, by setting up an electric rotating shaft two, when the device enters the pipeline, the rotation of the electric rotating shaft two makes the track fit the inside of the pipeline more closely, reducing the damage to the pipeline. At the same time, an electric rotating shaft three is set up so that the support frame rotates with the electric rotating shaft three, thereby adjusting the width of the device so that it can be adjusted according to the size of the pipeline, making it more widely used and easy to carry.

[0018] 2. This utility model incorporates a hydraulic telescopic rod 1, which extends and retracts during operation to adjust the position of the soft brush according to the pipe diameter, thereby cleaning impurities inside the pipe and facilitating measurement.

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] Example 1

[0027] like Figures 1-4 As shown;

[0028] This utility model provides a retractable tracked magnetic particle inspection machine for pipelines, including a device body 1. The device body 1 has a connecting plate 14 fixedly mounted on its outer side. A fixing plate 15 is fixedly mounted below the connecting plate 14. An electric rotating shaft 16 is fixedly mounted inside the fixing plate 15. A connecting block 17 is rotatably mounted outside the electric rotating shaft 16. An electric rotating shaft 18 is fixedly mounted outside the connecting block 17. A support frame 19 is rotatably mounted inside the electric rotating shaft 18. A fixing rod 20 is fixedly mounted inside the support frame 19. When the device enters the pipeline, the rotation of the electric rotating shaft 16 makes the track 25 fit more closely to the inside of the pipeline, reducing damage to the pipeline. At the same time, the electric rotating shaft 18 makes the support frame 19 rotate with the electric rotating shaft 18, thereby adjusting the width of the device.

[0029] In this embodiment, one end of the support frame 19 is rotatably equipped with an electric rotating shaft 22. A connecting block 21 is fixed inside the electric rotating shaft 22, and a fixing plate 23 is fixed below the connecting block 21. A connecting rod 24 is fixed inside the fixing plate 23, and a track 25 is fixed inside the connecting rod 24. A rubber pad 2 is fixed to the outside of the track 25. The electric rotating shaft 22 allows the support frame 19 to rotate with it, causing the track 25, which is fixed to the fixing plate 23 by the connecting rod 24, to rotate and adjust according to the pipe diameter. The rubber pad 2 prevents the track 25 from scratching the inside of the pipe during operation. Connecting discs 5 are fixed on both the upper and lower sides of the device body 1. A hydraulic telescopic rod 4 is fixed above the connecting discs 5, and a soft brush 3 is fixed above the hydraulic telescopic rod 4. The hydraulic telescopic rod 4 extends and retracts during operation, adjusting the position of the soft brush 3 according to the pipe diameter to clean impurities inside the pipe for easy measurement. A hydraulic telescopic rod 13 is fixedly installed. A liquid storage tank 12 is fixedly installed on the left side of the hydraulic telescopic rod 13. A connecting ring 6 is fixedly installed on the left side of the liquid storage tank 12. A circular hole 7 is opened inside the connecting ring 6. The hydraulic telescopic rod 13 is set so that the liquid storage tank 12 and the connecting ring 6 extend out of the device body 1. Magnetic powder is sprayed into the pipeline through the circular hole 7 for flaw detection. A hydraulic telescopic rod 11 is fixedly installed inside the connecting ring 6. A baffle 8 is fixedly installed on the left side of the hydraulic telescopic rod 11. An electric rotating shaft 9 is fixedly installed inside the baffle 8. A high-definition camera 10 is fixedly installed outside the electric rotating shaft 9. After the magnetic powder spraying is completed, the hydraulic telescopic rod 11 is activated so that the high-definition camera 10 extends to photograph the inside of the pipeline. The electric rotating shaft 9 then provides a comprehensive view of the inside of the pipeline, making the flaw detection more accurate.

[0030] Working principle and process of retractable tracked pipe magnetic particle inspection machine:

[0031] When in use, the retractable tracked magnetic particle inspection machine for pipelines operates by rotating the electric shaft 26 to make the track 25 parallel to the ground. The liquid storage tank 12 and connecting ring 6 extend from the main body 1 via the hydraulic telescopic rod 313. Magnetic powder is sprayed onto the outside of the pipeline through the round hole 7 for external inspection. After the external inspection is completed, as the device enters the pipeline, the rotation of the electric shaft 26 makes the track 25 fit more closely to the inside of the pipeline. Then, one end of the support frame 19 rotates with the electric shaft 318, and the other end of the support frame 19 rotates with the electric shaft 422. The movement causes the track 25, which is fixed to the fixed plate 23 by the connecting rod 24, to rotate, adjusting it according to the diameter of the pipe. Then, the liquid storage tank 12 and the connecting ring 6 extend out of the device body 1 through the hydraulic telescopic rod 13, spraying magnetic powder through the round hole 7 to the outside of the pipe for flaw detection. The hydraulic telescopic rod 11 is activated, causing the high-definition camera 10 to extend and capture images of the inside of the pipe. The electric rotating shaft 9 then captures images of the inside of the pipe from all angles. This design makes it more widely used, easier to carry, and more accurate in flaw detection.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
