Magnetic adsorption device and crawling robot

Abstract

The invention relates to a magnetic adsorption device and a crawling robot. The magnetic adsorption device is applied to the crawling robot, and the crawling robot comprises a frame and a moving mechanism arranged on the frame. The magnetic adsorption device comprises a plurality of magnetic adsorption assemblies and a plurality of stretchable mechanisms, wherein the magnetic adsorption assembliesare arranged below the frame in an array mode, and each magnetic adsorption assembly is correspondingly provided with at least one of the stretchable mechanisms; and first ends of the stretchable mechanisms are connected to the frame, and second ends of the stretchable mechanisms are connected to the magnetic adsorption assemblies, so that a gap between the magnetic adsorption assemblies and a to-be-adsorbed surface is changed. The magnetic adsorption device can adapt to the curved surfaces of different radians so as to enable the gap between the magnetic adsorption assemblies and the to-be-adsorbed surface to be adjusted according to requirements, so that it is guaranteed that the crawling robot obtains enough suction and stably crawls.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a magnetic adsorption device and a crawling robot. Background technique [0002] When the magnetic adsorption crawling robot crawls on the steel magnetic surface, most of them adopt the way of NdFeB magnetic adsorption. The crawling robot is suitable for a flat plane and a curved surface corresponding to a large diameter, and the movement of the crawling robot is realized by adjusting the gap between the NdFeB and the adsorption surface. [0003] However, for a curved surface with a small radius or a wavy surface, the gap between the NdFeB and the adsorption surface cannot be effectively controlled. If the gap is too large and the magnetic adsorption force is too small, the crawling robot cannot be effectively adsorbed on the crawling surface; If the gap is too small and the magnetic adsorption force is too large, crawling will be difficult and the ability of the craw...

Problems solved by technology

[0003] However, for a curved surface with a small radius or a wavy surface, the gap between the NdFeB and the adsorption surface cannot be effectively controlled. If the gap is too large and the magnetic adsorption force is too small, the crawling robot cannot be effectively adsorbed on the crawling surface; If the gap is too small and the magnetic adsorption force is too large, crawling will be difficult, and the ability of the crawler to overcome obstacles will be reduced.
