Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline weld inspection technology, specifically to a magnetic particle inspection device for pipeline weld inspection. Background Technology
[0002] When inspecting the quality of pipeline welding, non-destructive testing methods are often used to check for cracks and defects in the weld. Among conventional testing methods such as radiography, ultrasound, magnetic particle testing, and penetrant testing, magnetic particle testing is widely used due to its advantages of simple process, fast inspection speed, and high sensitivity in detecting cracks and defects. For example, the patent technology disclosed in prior art announcement number CN221426538U discloses a magnetic particle testing device for pipeline weld inspection, including a frame, a support on the frame, and a clamp for holding and fixing the pipeline to be inspected. The support is equipped with a detection component that can rotate and translate. The detection component includes a magnetic steel shell and a magnetic yoke detection component. A first coil along the axial direction of the pipeline to be inspected is disposed inside the magnetic steel shell, and the magnetic yoke detection component is fixed. The magnetic yoke detection assembly, specifically connected to the magnet housing, includes a connecting seat, an outer sleeve, and an iron core. The connecting seat is fixedly connected to the magnet housing. Two sets of outer sleeves are rotatably connected to the connecting seat, and a telescopic connecting rod is provided between the two sets of outer sleeves, with locking bolts on the telescopic connecting rods for locking their length. The iron core is slidably sleeved inside the outer sleeve, with a yoke head connected to the end of the iron core. A second coil is provided outside the iron core, with the second coil perpendicular to the direction of the first coil. An adjusting nut is also provided on the outer sleeve, and the adjusting nut is connected to the yoke head via an adjusting connecting rod. The telescopic length of the iron core and the yoke head can be controlled by adjusting the nut.
[0003] When the above-mentioned device is used, it can detect cracks and defects in all directions on the weld, preventing missed detections to the greatest extent. It is also more convenient to operate, eliminating the need to repeatedly place the magnetic yoke, and is more efficient. However, the pipe is heavy, making the operation more cumbersome when loading and unloading the pipe body. In addition, it cannot perform magnetic particle testing on long pipes.
