It utilizes the difference in magnetic permeability between the surface and near-surface defects of steel products (such as cracks, slag inclusions, hairline, etc.) and the magnetic permeability of steel. After magnetization, the magnetic field at the discontinuity of these materials will be distorted, forming a leakage magnetic field on the surface of the workpiece where some magnetic flux leaks, thereby attracting magnetic powder to form magnetic powder accumulation at the defects - magnetic traces.

[0030] The present invention provides a flaw detection device, comprising:

[0031] The detection unit 1 includes a detection magnet 101 and a material output port 103. The detection magnet 101 can magnetize the workpiece to be detected. The material output port 103 is connected to the detection medium and is arranged toward the workpiece to be detected.

[0032] The motion unit 2 includes a running wheel assembly 201 and a driving element 202, and the driving element 202 is connected to the running wheel assembly 201 by transmission;

[0033] The support unit 3 includes a support frame 301 , on which the detection unit 1 and the motion unit 2 are both arranged, and the walking wheel assembly 201 can drive the support frame 301 to move.

[0034] In the detection and flaw detection device of the present invention, the motion unit 2 can drive the detection unit 1 to move along the workpiece to be detected, and the detection unit 1 uses the material output port 103 to output the detection medium to detect the damage of the workpiece. The support unit 3 provides an installation foundation and support for the detection unit 1 and the motion unit 2. The present invention uses the motion unit 2 to drive the detection unit 1 to move to detect the workpiece to be detected, thereby reducing the labor burden of the operator and improving the work efficiency of workpiece detection. In this specific embodiment, the detection magnet 101 is a coil 102 surrounding the iron core, and the coil 102 is connected to a power supply. In actual work, the detection magnet 101 can also be selected according to the detection needs.

[0035] In this specific embodiment, the detection unit 1 also includes a liquid storage tank 104 capable of accommodating a detection medium. The detection medium is a magnetic suspension. The liquid storage tank 104 is connected to the material output port 103. The liquid storage tank 104 is fixed on the support frame 301. The liquid storage tank 104 is provided to facilitate the detection medium to move along the workpiece to be detected with the moving unit 2, thereby improving the convenience and continuity of detection.

[0036] In addition, the liquid storage tank 104 is connected to a spray pipe 105, which is connected to the material output port 103. The detection medium is sprayed out from the material output port 103 through the spray pipe 105. The material output port 103 is set at the bottom of the detection magnet 101 to ensure that the detection medium can be sprayed onto the workpiece to be detected. In other specific embodiments of the present invention, a pump body is set in the liquid storage tank 104 to ensure the smooth output of the detection medium and improve the reliability of the device.

[0037] Specifically, the detection unit 1 further includes a fixing frame 106 , on which the detection magnet 101 is disposed. The fixing frame 106 provides a mounting base for the detection magnet 101 , and the fixing frame 106 is connected to the supporting frame 301 to improve the overall stability of the device.

[0038] More specifically, the walking wheel assembly 201 includes a driving wheel 203, a driven wheel 204 and a track 205. The driving wheel 203 is connected to the driving element 202 by transmission. The track 205 is wound around the driving wheel 203 and the outside of the driven wheel 204. The driving wheel 203 drives the driven wheel 204 to move by the track 205. In this specific embodiment, the number of the driving wheel 203 and the driven wheel 204 are both two. The driving wheel 203 and the driven wheel 204 are surrounded by a rectangle and arranged at the four corners of the bottom of the support frame 301. While driving the device to move, the force uniformity of the walking wheel assembly 201 is improved; in other specific embodiments of the present invention, the number and arrangement of the walking wheel assembly 201 can be set according to the overall structure of the device. It should also be noted that the driving wheel 203 is connected to the driving element 202 by transmission. The driving element 202 can be a motor. In order to further improve the structural integrity and work convenience of the device, the driving element 202 is connected to a power supply component, which provides a power source for the driving element 202.

[0040] In addition, during the detection process, the device may need to move upward to adapt to the workpiece to be detected, or change the position of the workpiece to be detected to facilitate the smooth progress of the detection. In order to further improve the adaptability of the device, the motion unit 2 also includes an adsorption component 207, which is connected to the walking wheel component 201. The adsorption component 207 can be adsorbed on the workpiece to be detected. When the adsorption component 207 is adsorbed on the workpiece to be detected, it does not affect the movement of the walking wheel component 201. The adsorption component 207 can achieve the "climbing" of the device, so that the device can adapt to various shapes of workpieces to be detected, such as performing circumferential seam and longitudinal seam flaw detection in spherical tanks, thereby improving the adaptability of the device. In other specific embodiments of the present invention, the adsorption component 207 can be provided with a plurality of adsorption elements, which are connected to each driving wheel 203, driven wheel 204 and arc adaptive wheel 206 to ensure that the device can move along various shapes of workpieces to be detected, while preventing the device from falling, and ensuring the safe operation of the device.

[0041] Furthermore, the detection and flaw detection device also includes a control unit 4, which is connected to an encoder 401. The encoder 401 is connected to the walking wheel assembly 201 by a connecting rod. The encoder 401 is fixed on the support frame 301.

[0042] Correspondingly, the walking wheel assembly 201 also includes a roller 208, which is rotatably arranged on the support frame 301. The roller 208 is located at the bottom of the encoder 401. The roller 208 is arranged so that the control unit 4 can move smoothly with the device, avoiding uneven force on the motion unit 2, affecting the overall movement of the device, and ensuring smooth detection work.

[0043] It should also be emphasized that the detection unit 1 also includes a lighting lamp 107 and a wide-angle camera 108. The lighting lamp 107 and the wide-angle camera 108 are both arranged at the bottom of the material output port 103. The wide-angle camera 108 is arranged toward the material output port 103 and can record the flaw detection results, further improving the detection work efficiency and reducing the labor burden of the operator. The lighting lamp 107 can ensure the normal operation of the wide-angle camera 108. The lighting lamp 107, the wide-angle camera 108 and the control unit 4 are all connected to the power supply component to ensure energy supply, reduce line connections, and make the device structure compact.
