The utility model relates to an ultra-high voltage dual-traction walking board which is characterized in that the rear surface of a towing plate is connected with a rear supporting plate by a hinge, the towing plate comprises an upper cover plate and a lower cover plate, wherein a space formed by the upper cover plate and the lower cover plate is internally provided with clamping wheels, a wireless emitter, idler wheels, a gearwheel, a pinion and a photoelectric counter; the clamping wheels are arranged on two sides of the upper cover plate and the lower cover plate, the gearwheel and a plurality of idler wheels are arranged along the peripheries of the upper cover plate and the lower cover plate, the gearwheel is meshed with the pinion, the pinion is connected with the photoelectric counter which is connected with the wireless emitter, a towing wire cable bypasses the plurality of the idler wheels and the gearwheel and passes through the clamping wheels at the two sides to extend out the upper cover plate and lower cover plate; and the rear supporting plate comprises lateral connecting blocks and a middle connecting block, wherein two ends of the middle connecting block are welded with the lateral connecting blocks. The mode of traction at two ends reduces the investment of large-tonnage devices; two pairs of the clamping wheels guarantee that the towing wire cable can not break, thus eliminating the potential safety hazard; and the dismantling of the connecting blocks realizes conversion between the walking boards of 'dual-traction (six)' and 'dual-traction (eight)', thus expanding the universality of the walking board and reducing construction investment.
