Abstract

The invention discloses a wall-climbing robot which comprises a power system, an adsorption system and a control system. The power system comprises a wheel, a driving motor, a rotating disc, a linear motor, a pushing rod and a connecting rod. The adsorption system comprises a high-speed motor, a fan, labyrinth cavities and a vacuum air supplement valve device. Due to the multi-cavity structure, reliability and adaptability of the wall-climbing robot in the working process are improved. Meanwhile, due to the vacuum air supplement valve device, the walking driving force of the wall-climbing robot is more stable, and adaptability of the wall-climbing robot to different wall faces is improved. The wall-climbing robot can be used for conducting crack inspection on a nuclear waste liquid tank and a reactor pressure tank, conducting thickness measurement and weld joint flaw detection, conducting coating on large wall faces, cleaning the glass wall faces, installing ceramic tiles, conducting bridge flaw detection and conducting inspection, measurement and maintenance on the inner wall face and the outer wall face of a large circular tank or a spherical tank, and can also be used for conducting rust removal, spray coating and the like on a ship.

Description

technical field [0001] The invention relates to the field of wall-climbing robots, in particular to a multi-cavity crab-type negative pressure wall-climbing robot utilizing the principle of continuous negative pressure and adopting a multi-cavity adsorption structure. Background technique [0002] As a special branch of robots, wall-climbing robots are characterized by being able to move freely on walls and ceilings against the force of gravity. Due to the particularity of the work of wall-climbing robots, it has attracted the attention of scientific researchers from all over the world. [0003] With the emergence of high-rise buildings in cities, the problem of high-rise operation follows. At present, the application of wall-climbing robots is mainly concentrated in the following fields: in the nuclear industry, it is used for crack inspection, thickness measurement and weld seam inspection of nuclear waste liquid tanks and reactor pressure tanks; in the construction indus...
