Novel universal rolling magnet-wheel device for magnetic adsorption climbing robot

Abstract

The invention belongs to the technical field of robots and particularly relates to a novel universal rolling magnet-wheel device for a magnetic adsorption climbing robot. The novel universal rolling magnet-wheel device comprises an annular permanent magnet, all-dimensional wheels are arranged on two sides of the annular permanent magnet, and each all-dimensional wheel comprises a first hub, rollers, a sleeve, a roller shaft and a second hub which are sequentially arranged. The structure of the all-dimensional wheels is that the rollers capable of rotating around self axles are arranged on the peripheries of the hubs, the rollers are evenly distributed on the peripheries of the hubs, the axles of the rollers are orthogonal to axles of the hubs, and the all-dimensional wheels on the two sides are arranged in stagger to enable axial projection of the rollers of the all-dimensional wheel on one side to be located in the middle of the two rollers of the all-dimensional wheel on the other side. The novel universal rolling magnet-wheel device has the advantages that when wheels have axial movement trends along the wheels, the rollers of the all-dimensional wheels on the two sides are contacted with the ground and rotate around the self axles to enable the wheel to keep in a pure rolling state and improve flexibility of movement of the wheels.

Description

technical field [0001] The invention belongs to the technical field of robots, and specifically relates to a novel universal rolling magnetic wheel device for a magnetic adsorption wall climbing robot. Background technique [0002] The magnetic adsorption wall climbing robot is a kind of special robot, which is an automatic mechanical device designed to perform specific operations on the magnetic wall surface under harsh, dangerous and extreme conditions, such as inspection, testing, welding, grinding, etc. ,More and more attention has been paid. At present, magnetic adsorption wall-climbing robots have been widely used in the production and construction of ferromagnetic structures such as nuclear industry, petrochemical industry, construction industry, fire department, and shipbuilding industry. [0003] After literature search, it is found that the Chinese patent publication number is CN101612731A, the application date is July 23, 2009, and the title of the invention is: ...

AI Technical Summary

Problems solved by technology

[0006] The comparison file is just a simple combination of ordinary universal scroll wheel and magnet, the disadvantages include, large size, poor steering flexibility

To sum up, the disadvantages of the existing driving wheels of magnetic adsorption wall-climbing robots mainly include: the wheels can only rotate around the axle, that is, they can only roll in the direction perpendicular to the axis, and there is slippage when the wheels have an axial movement tendency. Phenomenon, poor motor flexibility
