Problems solved by technology

Although the current magnetic adsorption unit has a large adsorption force, its pull-up force is also large, which requires a large output torque of the motor and a high requirement for the strength of the flexible track; secondly, this type of track is usually tensioned by spring force. When crawling, when using this tensioning method, it is difficult for the track to adapt to the change of the curved surface

Abstract

The invention discloses a magnetic absorbing unit for an underwater magnetic absorbing wheel-pedrail climbing robot and relates to a structural design of the magnetic absorbing unit for the magnetic absorbing wheel-pedrail climbing robot. The magnetic absorbing unit comprises a magnetic isolating housing and a yoke, and a first absorbing magnetic block, a second absorbing magnetic block, a first magnetic conductive steel plate, a second magnetic conductive steel plate, a first regulating magnetic block, a second regulating magnetic block, a lower magnetic isolating block and an upper magneticisolating block which are arranged below the yoke respectively form a lower absorbing magnetic circuit and an upper regulating magnetic circuit. The magnetic absorbing unit has simple structure and easy implementation; due to the increase of the regulating magnetic circuit, when the corresponding fixed magnetic absorbing unit is arranged above the pulling-up position of the magnetic absorbing unit, the fixed magnetic absorbing unit and the regulating magnetic circuit attract each other, thereby reducing the pulling-up force and achieving the purposes of reducing the power of a motor and reducing the loads of a flexible crawler. If the fixed absorbing unit is arranged at the tensioning position of the flexible crawler, the fixed absorbing unit can carry out non-contact tensioning on the flexible crawler, thereby solving the contradiction between the tensioning and sealing of the underwater wheel-pedrail magnetic absorbing climbing robot.

Description

technical field [0001] The invention relates to a magnetic adsorption unit structure for a magnetic adsorption wheel-track crawler robot, in particular to a magnetic adsorption structure for an underwater wheel-track magnetic adsorption crawler robot. Background technique [0002] The development of modern industry and manufacturing technology has led to more and more applications of important large-scale structural parts. The welding, testing and maintenance of such components must be done on-site. To realize automatic welding, testing and maintenance, crawling The robot as a work platform is the key to realization. [0003] The permanent magnet adsorption wheel-track crawler robot is an ideal working platform for this type of structure due to its simple structure and strong adsorption force. The adsorption force generated by the magnetic adsorption unit fixed in the flexible track enables the robot to crawl on the workpiece; therefore, the structure of the magnetic adsorp...
