[0002] Magnetic particle inspection, also known as magnetic particle flaw detection, or MT for short, involves applying a magnetic field to the workpiece to magnetize it. Magnetic lines of force escape from the workpiece surface and near-surface defects, creating a leakage magnetic field. The presence of magnetic poles attracts the magnetic particles applied to the workpiece surface, forming aggregated magnetic traces that reveal the presence of defects. However, during the use of existing technology, the inventors discovered the following problems; In the current inspection process, a contrast enhancer is first sprayed onto the weld seam of the workpiece. Then, an AC magnetic yoke flaw detector is held at the weld seam, followed by the spraying of black water magnetic suspension in conjunction with the AC magnetic yoke flaw detector to reveal defects at the weld seam. The inspection process requires the operator to hold the tools, and the weight of the AC magnetic yoke flaw detector can cause fatigue during long hours of work. Furthermore, it is also quite troublesome when inspecting the inside of pipe fittings. Therefore, the current technology has certain drawbacks.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0018] like Figure 1 As shown, a magnetic particle inspection and positioning device for pressure pipeline welds includes: The limiting device includes a detection table 10, two bases 13 are provided on the top wall of the detection table 10, and the top walls of the two bases 13 are both arc-shaped. Two electric push rods 21 are also provided on the right side of the top wall of the detection table 10, and a detection element 15 is also provided on the top wall of the detection table 10. The detection device includes two fixed sleeves 23. An AC magnetic yoke flaw detector 16 is fixedly sleeved inside the cavity of the fixed sleeve 23. A fixed frame 27 is fixedly installed on both the left and right sides of the fixed sleeve 23. A rubber collar 28 is provided inside the cavity of the fixed frame 27. A black water magnetic suspension bottle 25 and a contrast enhancer bottle 24 are fixedly installed in the cavities of the two rubber collars 28, respectively.

[0019] It is worth noting that the AC magnetic yoke flaw detector 16 belongs to the category of magnetic particle flaw detectors. This device includes AC, DC, and AC / DC dual-use models, equipped with rechargeable batteries to support DC power supply, and is suitable for outdoor environments without power supply and for high-pressure containers, bridges, pipelines, and other similar scenarios.

[0020] Contrast enhancer bottle 24: Contrast enhancers are a class of auxiliary materials used to improve the contrast between two or more substances or structures. They highlight the difference between the target object and the background through physical or chemical action, so as to make observation, detection or imaging clearer.

[0021] Blackwater magnetic suspension bottle 25: Blackwater magnetic suspension is a detection medium specially designed for magnetic particle inspection. By uniformly dispersing magnetic particles in a liquid carrier, the magnetic powder is adsorbed by the leakage magnetic field to form visible magnetic traces, thereby revealing defects such as cracks and pores on or near the surface of ferromagnetic materials.

[0022] Electric spray head 29: An electric spray head is a device that achieves precise liquid spraying through electric power, widely used in agriculture, industry, medical fields, etc. Its core feature is that spraying parameters can be controlled by a motor or solenoid valve, making it more efficient, stable, and easier to automate compared to traditional manual spray heads. The AC magnetic yoke flaw detector 16, contrast enhancer bottle 24, black water magnetic suspension bottle 25, and electric spray head 29 are all existing technologies and will not be described in detail here. The display screen 12, AC magnetic yoke flaw detector 16, electric push rod 21, camera 26, electric spray head 29, and drive motor 31 are all electrically connected to the power supply and switch; the display screen 12 and camera 26 are electrically connected.

[0023] In practical use, the limiting device can limit the detection piece 15 through the two bases 13, and limit and position the two fixed sleeves 23 through the two electric push rods 21, thereby limiting the AC magnetic yoke flaw detector 16. The detection device can detect the weld of the detection piece 15 through the AC magnetic yoke flaw detector 16, the contrast enhancer bottle 24 and the black water magnetic suspension bottle 25.

[0024] In summary, by setting up a limiting device and a detection device, the limiting device can limit the detection part 15 and the detection device, and the detection device can detect the detection part 15 through the AC magnetic yoke flaw detector 16, the contrast enhancer bottle 24 and the black water magnetic suspension bottle 25. This eliminates the need for staff to hold the AC magnetic yoke flaw detector 16 and other equipment for detection, which can save time and effort for staff compared with existing technologies.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a first limiting cavity 14 is provided on the top wall of the detection platform 10, and a side cavity 19 is provided on both the front and rear side walls of the first limiting cavity 14. A limiting plate 17 is fixedly installed on the bottom wall of the base 13.

[0026] The limiting plate 17 is movably installed inside the first limiting cavity 14. A limiting block 18 is fixedly installed on both the front and rear side walls of the limiting plate 17, and the two limiting blocks 18 are respectively fixedly installed in the corresponding side cavities 19.

[0027] A vertical plate 11 is fixedly installed on the right side of the top wall of the testing platform 10. A display screen 12 is fixedly installed on the front side wall of the vertical plate 11. Two second limiting cavities 20 are opened on the side wall of the vertical plate 11, and two electric push rods 21 are respectively fixedly installed in the cavities of the two second limiting cavities 20.

[0028] In practical use, the staff moves the base 13 according to the different lengths of the test piece 15, limits the limiting plate 17 through the first limiting cavity 14, limits the limiting block 18 through the side cavity 19, and thus limits the base 13, so that the base 13 can move horizontally on the top wall of the test table 10. Then the test piece 15 is placed on the base 13 to limit the test piece 15. The upright plate 11 can limit the electric push rod 21 through the second limiting cavity 20.

[0029] In summary, by setting up the detection platform 10, the upright plate 11, the base 13, the first limiting cavity 14, the detection component 15, the limiting plate 17, the limiting block 18, the side cavity 19, the second limiting cavity 20, and the electric push rod 21, the base 13 can limit the detection component 15 of different lengths, the second limiting cavity 20 can limit the electric push rod 21, and the upright plate 11 can support the electric push rod 21 and the detection device.

[0030] like Figure 4 , Figure 5 and Figure 6As shown, a connector 22 is fixedly installed on the movable end of each of the two electric push rods 21. The connector 22 is U-shaped, and the inner side walls of the connector 22 are fixedly connected to the front and rear side walls of the fixed sleeve plate 23 respectively. A camera 26 is fixedly installed on one side wall of each of the two fixed sleeve plates 23.

[0031] A connecting block 31 is fixedly installed on both the front and rear side walls of the rubber collar 28. A rotating rod 34 is fixedly installed on the side wall of the two connecting blocks 31 that are far apart from each other. The rotating rod 34 passes through the fixed frame 27 and is movably connected to the through point of the fixed frame 27.

[0032] A fixed box 33 is fixedly installed on one side wall of the fixed frame 27. A drive motor 32 is fixedly installed inside the cavity of the fixed box 33. The output end of the drive motor 32 is fixedly connected to the corresponding rotating rod 34. The black water magnetic suspension bottle 25 and the contrast enhancer bottle 24 are both movably sleeved in the cavity of the rubber collar 28. An electric nozzle 29 is fixedly installed at the discharge port of the black water magnetic suspension bottle 25 and the contrast enhancer bottle 24.

[0033] In practical use, the movement of the movable end of the electric push rod 21 drives the connecting piece 22 to move, which in turn drives the fixed sleeve 23 to move. The movement of the fixed sleeve 23 then drives the fixed frame 27 to move. The movement of the fixed sleeve 23 and the fixed frame 27, in turn, drives the AC magnetic yoke flaw detector 16, the contrast enhancer bottle 24, and the black water magnetic suspension bottle 25 to move. The camera 26 observes the weld seam of the inspection piece 15. The fixed box 33 can limit the movement of the drive motor 32. When the output end of the drive motor 32 rotates, it drives the rotating rod 34 to rotate, which in turn drives the connecting block 31 to rotate. The rotation of connecting block 31 can drive the rubber collar 28 to rotate, which in turn drives the contrast enhancer bottle 24 and the black water magnetic suspension bottle 25 to rotate. The electric nozzle 29 sprays the material in the cavity of the contrast enhancer bottle 24 and the black water magnetic suspension bottle 25 onto the weld of the test piece 15. After the material in the cavity of the contrast enhancer bottle 24 is sprayed, the AC magnetic yoke flaw detector 16 is moved to the weld of the test piece 15 and the material in the cavity of the black water magnetic suspension bottle 25 is sprayed again. The AC magnetic yoke flaw detector 16 is used to reveal the gap at the weld, and then the image is observed through the camera 26 and transmitted to the display screen 12 for the staff to view.

[0034] In summary, by setting up a display screen 12, a test piece 15, an AC magnetic yoke flaw detector 16, an electric push rod 21, a connector 22, a fixing sleeve 23, a contrast enhancer bottle 24, a black water magnetic suspension bottle 25, a camera 26, a fixing frame 27, a rubber collar 28, an electric nozzle 29, a connecting block 31, a drive motor 32, a fixing box 33, and a rotating rod 34, the movement of the movable end of the electric push rod 21 can move the AC magnetic yoke flaw detector 16, the contrast enhancer bottle 24, and the black water magnetic suspension bottle 25. Through the coordinated operation of the AC magnetic yoke flaw detector 16, the contrast enhancer bottle 24, and the black water magnetic suspension bottle 25, the weld seam of the test piece 15 can be inspected, and the image can be transmitted to the display screen 12 for easy viewing by the staff.
