Adsorption system for sucked-crawler-type wall-climbing robot

Abstract

The invention discloses an adsorption system for a sucked-crawler-type wall-climbing robot, and belongs to the technical field of wall-climbing robot adsorption systems. The adsorption system mainly comprises two gas distribution disc assemblies, suction cup assemblies, an electromagnetic reversing valve and a vacuum pump, wherein the two gas distribution disc assemblies are coaxially connected with a driving wheel and a driven wheel of the wall-climbing robot correspondingly; and when the wall-climbing robot walks, a gas distribution channel of the suction cup assembly at the driving wheel position and tightly attaching the wall surface is opened, the vacuum pump enables a suction cup cavity to generate negative pressure through the gas distribution channel so as to press the wall surfacetightly, the negative pressure in a suction cup cavity of the suction cup assembly at the driven wheel position and tightly attaching to the wall surface is released though the gas distribution channel. The adsorption system is simple in pneumatic circuit, few in pipelines, convenient to arrange, low in failure rate, simple in gas distribution control, reliable in adsorption and free in walking.

Description

technical field [0001] The invention relates to the technical field of an adsorption system for a wall-climbing robot, in particular to an adsorption system for a suction cup crawler-type wall-climbing robot. Background technique [0002] Wall-climbing robots can be used in tank flaw detection inspection, cleaning and spraying of high-rise buildings, disaster rescue and other fields. The use of wall-climbing robots can liberate humans from dangerous operating environments, improve work efficiency, and reduce operating costs. A wall-climbing robot must have two basic functions of adsorption and movement, and the common adsorption methods include negative pressure adsorption and magnetic adsorption. Among them, the negative pressure adsorption can be adsorbed on the wall surface through the negative pressure generated in the suction cup, and is not limited by the wall surface material, so it has been widely used. The suction cup crawler wall-climbing robot has the advantages...
