[0002] Magnetic particle testing, also known as magnetic particle flaw detection, or MT in English, is a method of applying a magnetic field to the workpiece to magnetize it (whole magnetization or partial magnetization). Magnetic lines of force will escape from the surface of the workpiece at the surface and near-surface defects to form a leakage magnetic field. The presence of magnetic poles can adsorb the magnetic powder applied to the surface of the workpiece to form aggregated magnetic marks, thereby showing the presence of defects. The magnetic particle testing method is widely used, mainly to detect defects on the surface or near the surface of magnetic materials. It is mostly used to detect welds, castings or forgings, etc.

[0003] In the patent document with the announcement number CN207601004U, an electric auxiliary device for magnetic particle inspection of welds is provided, including an electric auxiliary device body, the electric auxiliary device body is a hollow box-type housing, and the electric auxiliary device body is provided with four groups of installation slots matching the magnetic yoke of the four-legged magnetic powder machine; the front and rear sides of the electric auxiliary device body are symmetrically provided with hubs, and the hubs are connected by a rotating shaft passing through the electric auxiliary device body, and the rotating shaft is connected to the motor in the electric auxiliary device body through a gear transmission assembly. The new structure is reasonably designed, making the installation of the four-legged magnetic powder machine convenient, and the motor drives the hub to rotate and then drives the device to roll on the outer surface of the metal pipe at a certain detection speed, which can not only save physical strength, but also improve the detection efficiency and ensure the detection accuracy.

[0004] When the above device is in use, the wheels on both sides are not stable enough when moving, which may cause rollover and affect the normal detection. In addition, the size of the slot is fixed and cannot be matched with the yoke of a four-legged magnetic powder machine of different specifications, which is inconvenient for staff to use. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a magnetic powder detection auxiliary device, which overcomes the shortcomings of the prior art and aims to solve the problem that when the above devices in the prior art are in use, the wheel hubs on both sides are not stable enough when moving, which may cause rollover and affect the normal progress of the detection, and the size of the slot is fixed and cannot be matched with the yoke of a four-legged magnetic powder machine of different specifications, making it inconvenient for staff to use.
