Abstract
The invention discloses an obstacle-crossing mechanism of a rod piece climbing robot. The obstacle-crossing mechanism comprises a machine body, surrounding mechanisms and climbing mechanisms. The machine body is provided with two arc-shaped guide grooves formed in parallel, the number of the surrounding mechanisms is two, the two surrounding mechanisms are reversely arranged and the two surrounding mechanisms each are coaxially matched with one guide groove, and the climbing mechanisms are arranged on the surrounding mechanisms. The obstacle-crossing mechanism is simple and compact in structure and low in production cost. Through the combination of the two groups of surrounding mechanisms and the climbing mechanisms, obstacle crossing can be performed on obstacles at a height of +/-200 mm under the joint effects of multiple groups of flexible joints and springs; and through the track type climbing mechanisms, the climbing robot can climb on a rod piece quickly. Since the two groups of surrounding mechanisms work respectively, obstacle crossing can be performed quickly, the adaptability is high, the speed is very quick, obstacles can be crossed quickly, and intermediate complex control steps are reduced.
