Abstract

The invention provides a novel magnetic adsorption type wall-climbing wheel, which comprises a driving motor, a speed reducer, driving wheels and a permanent magnet adsorption device. The driving wheels are fixed on a transmission shaft. The transmission shaft and the speed reducer are both fixed through a mounting plate. Under the speed reducer, the permanent magnetic adsorption device is arranged between the two driving wheels. The permanent magnet adsorption device comprises a sector yoke, arc magnets and a magnet isolator. During operation, the permanent magnet adsorption device is not incontact with a magnetic conductive wall surface, so the magnetic energy product of the magnet can be maximally utilized to reduce the magnetic leakage and sufficiently reduce the magnet mass. The magnetic adsorption type wall-climbing wheel provided by the invention can adapt to complex working conditions, has a good obstacle-crossing capability and has a good application prospect in the production and maintenance work of ships and petrochemical industries.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a magnetic adsorption type climbing wheel. Background technique [0002] Due to its stable adsorption capacity and high load capacity when facing metal walls, magnetic adsorption wall-climbing robots are widely used in production and maintenance operations in shipbuilding, petrochemical and other industries. The magnetic adsorption wall-climbing wheel is an important unit of the wheeled magnetic adsorption wall-climbing robot. The quality of the magnetic adsorption wall-climbing wheel determines the adsorption stability, load capacity and flexibility of the entire wheeled wall-climbing robot. Among them, although the existing wheeled magnetic adsorption wall-climbing robots have the advantages of good flexibility, they generally have the defects of low utilization rate of magnetic energy and weak load capacity. Contents of the invention [0003] The purpose of the present inven...
