Wall-climbing vacuum suction caterpillar chassis

Abstract

The invention provides a wall-climbing vacuum suction caterpillar chassis. The wall-climbing vacuum suction caterpillar chassis comprises two composite caterpillars supported by driving wheels and driven wheels jointly, an intermediate support arranged between the two composite caterpillars, driving motors arranged on the intermediate supports and rotatably connected with the inner sides of the driving wheels and pneumatic rotating connectors rotatably connected on the outer sides of the driving wheels. Each composite caterpillar comprises an inner layer, a suction disc layer, a first vacuum self-closing valve, a plurality of second vacuum self-closing valves, driving wheel inner through holes, sponge suction discs, caterpillar ventilating grooves, and a vacuum pump, wherein the suction disc layer is fixedly connected with the inner layer; the first vacuum self-closing valve is arranged in the corresponding driving wheel and communicating with the corresponding pneumatic rotating connector; the multiple second vacuum self-closing valves are arranged in the inner layer; the one ends of the driving wheel inner through holes communicate with inner layer through holes, and the other ends of the driving wheel inner through holes communicate with the first vacuum self-closing valve; the sponge suction discs are formed in the suction disc layer; one ends of the caterpillar ventilating grooves are opened in the sponge suction discs, and the other ends of the caterpillar ventilating grooves communicate with the second vacuum self-closing valves; and the vacuum pump communicates with the corresponding pneumatic rotating connector. The wall-climbing vacuum suction caterpillar chassis can travel on surfaces with various roughness degrees.

Description

technical field [0001] The invention relates to a wall-climbing vacuum adsorption crawler chassis, which belongs to the field of wall-climbing robots. Background technique [0002] Existing wall-climbing robots have two types of adsorption, one is vacuum adsorption, and the other is magnetic adsorption. The existing window-cleaning robot produced by vacuum adsorption, such as Cobos, has the disadvantage that it can only move on smooth glass and has poor adaptability; The adsorption robot can only move on the steel plate, which is also poor in adaptability. Contents of the invention [0003] The object of the present invention is to provide a wall-climbing vacuum adsorption crawler chassis to solve the above problems. [0004] The present invention adopts following technical scheme: [0005] A wall-climbing vacuum adsorption crawler chassis is characterized in that it includes: two composite crawlers, a driving wheel, which is arranged at one end of the composite crawler,...
