Abstract

The invention discloses an obstacle-crossing wall-climbing robot combined variable magnetic force attraction module. The obstacle-crossing wall-climbing robot combined variable magnetic force attraction module comprises a screw assembly and an attraction assembly; the screw assembly adopts a motor-belt wheel-belt-belt wheel-screw nut-screw power transmission mode so that a screw nut can drive a screw to move up and down, and accordingly, the attraction assembly is driven to move outside a vehicle frame up and down. The problem that when an existing permanent-magnetic wall-climbing robot operates on a large-size metal vertical face, the magnetic force cannot be changed is solved; through application of reverse motion of a screw mechanism, a permanent-magnetic attraction mechanism of the previous permanent-magnetic wall-climbing robot is perfected, thus, the magnetic force of a magnet can be changed along with changing of the shape of a wall obstacle in the robot obstacle crossing process, and the all-terrain adaptability is more excellent; magnetic induction line distribution of the combined variable magnetic force attraction module is improved, and the stability and safety of the robot in the operating process are improved; and by applying an electromagnet, the attraction force generated by the combined variable magnetic force attraction module can be adjusted more easily.

Description

technical field [0001] The invention relates to the technical field of an adsorption device for a wall-climbing robot, in particular to a composite variable magnetic force adsorption module for an obstacle-climbing robot. Background technique [0002] At present, the maintenance and construction operations of large metal facades such as petrochemical storage tanks and ships at home and abroad have increasingly stringent requirements for environmental protection, personal safety, and low cost and high efficiency. The automatic equipment that absorbs and moves on the metal facade has wide application prospects. [0003] Because permanent magnet adsorption has the advantages of stable and large adsorption force, wall-climbing robots applied to metal facades mostly use permanent magnets as the main adsorption mechanism to ensure that the robot can run on the wall. Most of the permanent-magnet wall-climbing robots on the market use fixed magnetism. No matter what the wall enviro...
