Gap type negative pressure adsorption wall-climbing robot

Abstract

The invention relates to a gap type negative pressure adsorption wall-climbing robot, comprising a bottom plate, a negative pressure generating device, a sealing device, an advancing device and an electric control device, wherein the advancing device is of a dual-crawler type structure; the bottom plate comprises an upper bottom plate and a lower bottom plate, the upper bottom plate covers on thelower bottom plate, the lower bottom plate is suspended below the upper bottom plate by a support pillar, an air inlet hole is formed in the center of the lower bottom plate, a gap is reserved betweenthe peripheral edge of the lower bottom plate and the periphery of the upper bottom plate instead of connection, a flow guide chamber is formed between the upper and lower bottom plates, crawler walking troughs are formed in the lower bottom plate in bilateral symmetry by taking the air inlet hole as a center; the sealing device comprises a flow guide mechanism and a flow stop mechanism, the flowguide mechanism is obliquely arranged in the gap between the peripheries of the upper and lower bottom plates, the flow stop mechanism is arranged on the bottom surface of the lower bottom plate, anda plurality of quantity of sealing bulges are uniformly distributed on the lower surface of the flow stop mechanism. The robot is applicable to common wall surfaces, and meanwhile solves conflict between adsorption force and resistance in the negative pressure adsorption process, so as to flexibly move on the wall surface.

Description

Technical field: [0001] The invention belongs to the field of wall-climbing robots, in particular to a gap-type negative pressure adsorption wall-climbing robot Background technique: [0002] The research and application of wall-climbing robots have extremely important engineering application background and very broad application prospects. At present, the adsorption methods of wall-climbing robots include magnetic adsorption, vacuum adsorption, and negative pressure adsorption. [0003] Among them, magnetic adsorption is only suitable for the wall surface of ferromagnetic material, which has high requirements for the wall surface material. For example, a magnetic adsorption wall-climbing robot whose publication number is CN108749943A uses electromagnets to form an adsorption device, which is only suitable for walls made of ferromagnetic materials, and is inapplicable for ordinary walls, which has great limitations. A new type of robot that can be applied to various walls ...

Problems solved by technology

[0006] At present, traditional adsorption methods such as magnetic adsorption, vacuum adsorption, and negative pressure adsorption still have problems such as poor wall applicability, inability to move continuously, and high resistance to robot walking.
