Magnetism-adjustable permanent magnet wheel

Abstract

The invention provides a magnetism-adjustable permanent magnet wheel. The magnetism-adjustable permanent magnet wheel comprises an inner wheel assembly, an outer wheel assembly and a peripheral limiting structure, wherein the outer wheel assembly is rotatably fixed outside the inner wheel assembly in a sleeving manner; the peripheral limiting structure is used for peripherally limiting the inner wheel assembly and the outer wheel assembly; the inner wheel assembly comprises a permanent magnet; the outer wheel assembly comprises a plurality of first magnetism isolating sections and a plurality of magnetic conductive sections; the first magnetism isolating sections are distributed at intervals in the peripheral direction of the outer wheel assembly; each magnetic conductive section is inlaid between the two corresponding adjacent first magnetism isolating sections; and the first magnetism isolating sections and the magnetic conductive sections are matched to form an outer wheel body. According to the magnetism-adjustable permanent magnet wheel, the magnetism of the permanent magnet wheel can be adjusted according to requirements of the field. The magnetism-adjustable permanent magnet wheel has the advantages of convenience in adjustment, simple structure and high safety degree.

Description

technical field [0001] The invention relates to the field of wheels, in particular to a permanent magnet wheel with adjustable magnetic force. Background technique [0002] In the field of magnetic adsorption wall-climbing robots, permanent magnet wheels made of permanent magnet materials are mainly installed on the robot. However, the magnetic force of the existing permanent magnet wheels is generally not adjustable. When the wall-climbing robot is crawling, the magnetic force required by different crawling medium planes may usually be different. When the robot moves from one medium plane to another, it is not suitable for the current permanent magnet wheel. When working on a medium plane with magnetic force, the crawling work of the new medium plane can only be satisfied by exchanging permanent magnet wheels with different magnetic forces, which greatly limits the effective working range of the magnetic adsorption wall-climbing robot. In addition, when the wall-climbing r...

However, the magnetic force of the existing permanent magnet wheels is generally not adjustable. When the wall-climbing robot is crawling, the magnetic force required by different crawling medium planes may usually be different. When the robot moves from one medium plane to another, it is not suitable for the current permanent magnet wheel. When working on a medium plane with magnetic force, the crawling work of the new medium plane can only be satisfied by exchanging permanent magnet wheels with different magnetic forces, which greatly limits the effective working range of the magnetic adsorption wall-climbing robot.

In addition, when the wall-climbing robot sends a fault in a space with a small gap, it is difficult to take it out due to the strong magnetic force.

If brute force is used, it will cause damage to the wall-climbing robot or its working equipment
