The utility model discloses an electric aerodyne walking device which is used for driving an electric aerodyne to operate along a high-voltage power transmission line and comprises two supporting frames which are symmetrically arranged. Every two sets of walking assemblies are installed at the two ends of one supporting frame, and the walking assemblies can run on the wires; the obstacle crossingassembly is sleeved with the walking assembly and drives the walking assembly to cross an obstacle when encountering the obstacle; the reversing driving assembly is used for providing power for the obstacle crossing assembly; according to the utility model, the reversing driving assembly is arranged; the matching with the corresponding obstacle crossing assembly is switched; according to the electric aerodyne, the obstacle crossing action of the single walking assembly is achieved, so that the walking assemblies at the two ends of the supporting frame can cross obstacles independently, the electric aerodyne can cross the obstacles conveniently during forward operation or reverse operation, then maintainers can maintain wires conveniently, and the convenience of the electric aerodyne is improved.
