Description

TECHNICAL FIELD

[0001] The application relates to a switch type disc magnetic wheel. BACKGROUND

[0002] The magnetic wheel is applied to wall-climbing robot work wall surface adsorption, and maintains that the robot can be stably kept on a plane, a vertical plane, an inclined plane and the like working conditions.

[0003] The structure of a conventional disc type magnetic wheel is that after magnetic steel and hardware are matched and installed, the total magnetic flux is a constant value, that is, the magnetic attraction force is a constant value, and generally the single magnetic wheel attraction force is 50kg-400kg. Since the magnetic attraction force of the magnetic wheel is a constant value and always exists, the following problems exist in the use process: 1. The magnetic wheel or the installed equipment has the risk of being adsorbed together with other iron tools or materials in the storage, circulation and the like process; 2. In actual application, the wall-climbing robot needs the magnetic wheel to generate the attraction force to realize the wall-climbing function when working, but after the work is completed or the equipment needs to be maintained, the robot needs to be withdrawn, and the magnetic wheel is still tightly adsorbed on the working wall and is difficult to leave the working wall, so that a large manpower cost and time cost need to be invested to want to exit the working state, and the risk of equipment damage may exist in the process; 3. In a relatively complex working environment, the magnetic wheel surface magnetic loop path is easy to adsorb ferromagnetic impurities, causing the magnetic wheel attraction force to be reduced, the wall-climbing rolling resistance to be increased, and the normal operation of the equipment to be seriously affected. Since the magnetic field loop factor exists, the adsorbed ferromagnetic impurities are difficult to clean when the magnetic wheel is maintained, and the equipment maintenance cost is greatly increased.
