Problems solved by technology

[0003] At present, a variety of wall-climbing robots have appeared, which are used to absorb and walk on the wall of the ship. There is a general contradiction in the research of permanent magnet crawler wall-climbing robots. To improve the load capacity of the robot, it is necessary to increase the permanent magnet adsorption unit on the permanent magnet crawler. Adsorption force, the increase of the adsorption force will lead to large lateral friction when the robot turns, and the driving torque will be large, and the increase of the driving torque will cause the volume and weight of the driving element to increase

Embodiment Construction

[0023] The specific embodiments of the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings.

[0024] like Figure 1-2 As shown, the permanent magnet crawler 10 is made up of several permanent magnet adsorption units 20 and double-row roller chains 30, and the double-row roller chain is a double-row chain with bent plates and mounting holes, and then the permanent magnet adsorption units are installed on The curved plate of the chain is to reduce magnetic flux leakage and fully utilize the magnetic energy of the permanent magnet.

[0025] The permanent magnetic adsorption unit 10 adopts a B-type magnetic circuit, and is composed of two permanent magnets 21, a yoke 22 and a magnetic isolation plate 23. The yoke 12 is fixed in the installation hole of the curved plate of the double-row roller chain through screws and other parts. The way of screw fixing can be selected, the permanent magnet 21 is adsorbed on the yoke ...

Abstract

The invention relates to a magnetic circuit structure of a permanent magnet crawler for a wall climbing robot, which is composed of a permanent magnet adsorption unit and two rows of roller chains, wherein the double rows of chains with a bent plate and mounting holes are arranged on the bent plate of the chain, and the permanent magnet adsorption unit adopts a B magnetic circuit. The invention has the advantages that the weight of the robot and the weight of the equipment attached to the robot can be carried without falling off because the crawler has strong adsorption force, and the weight of the robot and the equipment attached to the robot can be carried without falling off because the crawler meets the needs of load, obstacle-crossing and power.

Description

technical field [0001] The invention relates to the field of robots, in particular to a magnetic circuit structure of a permanent magnet crawler of a wall-climbing robot. Background technique [0002] Ship derusting and cleaning is an important business in the shipbuilding industry. It is an indispensable part of shipbuilding and ship repairing. , Corrosion is inevitable. In order to improve the service life of the ship and increase the safety of use, when the outer wall of the ship is corroded to a certain extent, rust removal and cleaning must be carried out. [0003] At present, a variety of wall-climbing robots have appeared, which are used to absorb and walk on the wall of the ship. There is a general contradiction in the research of permanent magnet crawler wall-climbing robots. To improve the load capacity of the robot, it is necessary to increase the permanent magnet adsorption unit on the permanent magnet crawler. Adsorption force, the increase of the adsorption fo...
