All-condition wiring robot for 500kV power transmission line

The utility model discloses a 500kV power transmission line all-condition wiring robot which comprises a middle coupling arm and a rear coupling arm, the lower end of the middle coupling arm is sleeved with a double-arm unfolding device, the outer wall of the lower portion of the double-arm unfolding device is provided with an adapter plate, and the left side and the right side of the adapter plate are sleeved with synchronous belts. A rotating motor and three pairs of arm double-hanging devices are connected to the lower portions of the two synchronous belts in a sleeving mode, the travel ofa line is well enveloped through a traveling wheel train and arm hanging wheels, and the traveling characteristic is kept while the lightweight design is kept; the pressing wheel train is connected with the hanging arm wheel train, so that the double arms keep light, meanwhile, the friction force of the walking wheels is increased through the clamping wheel train, and stable walking is achieved ona large-gradient four-spl
