The invention belongs to the technical field of electric power systems, and relates to a high-voltage electrified aerial bare conducting wire lifting crane and a rubber coating spray painting robot ofthe high-voltage electrified aerial bare conducting wire lifting crane. A lifting device in the lifting crane comprises a wire speed adjusting device and wire winding devices, wherein the wire speedadjusting device is installed in the middle of the upper end of a machine frame, and the wire winding devices are installed on the two sides of the wire speed adjusting device. The wire speed adjusting device comprises a supporting frame, a worm and a worm wheel, wherein the supporting frame is installed on the machine frame, the worm is arranged on the supporting frame, and the worm wheel mesheswith the worm. A second hand wheel is fixedly installed on the outer side of the worm wheel, and a plurality of third hand wheels are evenly and fixedly installed on the upper side of the worm wheel.Each wire winding device comprises a wire winding roller, a guide rod and a first hand wheel. The wire winding rollers are fixedly arranged at the free ends of the worm, the guide rods are fixedly arranged above the wire winding rollers, and the first hand wheels are installed on the outer sides of the wire winding rollers. Sliding blocks are arranged on the guide rod in a penetrative mode, and traction wheels are fixedly installed on the sliding blocks. Pull ropes which are used for lifting the rubber coating robot are wound around the wire winding rollers, and the free ends of the pull ropespass through the traction wheels. The problem that in the prior art, the potential safety hazard exists in the mode that an automatic spray painting robot is conveyed by a control system is solved.
