Novel magnetic attraction type wall climbing robot for sand blasting and rust removal of ship

Abstract

The invention relates to a novel magnetic attraction type wall climbing robot for sand blasting and rust removal of a ship. The robot comprises a walking device, an auxiliary sucker device, a power system and a wall climbing robot frame body. Magnet mounting plates for mounting rectangular permanent magnet blocks are made by stamping, magnet fixing plates are machined in the middle, and the bending resistance can be enhanced so that the rectangular permanent magnet blocks with a large attraction force can be installed without being deformed. An auxiliary sucker system is arranged at the frontend of the wall climbing robot body to increase the attraction torque, so that the anti-overturning capability is improved to adapt to climbing at different negative angles, and the load of the wall climbing robot is increased; an auxiliary sucker adopts permanent magnets and electromagnets for cooperative installation, a certain attraction force can be ensured under the condition of sudden powerfailure, and the power can be cut off when the auxiliary sucker needs to be removed. At the same time, universal wheels are arranged on the front and rear sides to decrease a frictional force during walking, a walking system is provided with spring dampers which automatically expand and retract to change the tightness degree of crawler belts when the robot climbs an obstacle, and therefore a stable attraction state can be maintained.

Description

technical field [0001] The invention relates to a novel magnetic adsorption wall-climbing robot used for sandblasting and rust removal of ships, and its application fields are rust removal of ships and large metal surfaces such as oil tanks in oil fields. Background technique [0002] In recent years, with the continuous development of science and technology, my country's research on sand blasting and derusting robots has made great progress. However, as ships become larger and larger, the load capacity, adsorption capacity and higher The obstacle capability requirements are getting higher and higher. Facing the working surface with welds and negative angles, the traditional magnetic adsorption wall-climbing robot blindly enhances the magnet adsorption force. When the magnet block behind the crawling wall-climbing robot leaves the working surface Excessive adsorption force causes bending and deformation of the magnet mounting plate, and it is difficult to remove when the robot...
