Insulation device for tower crane working near electromagnetic wave source and construction method of insulation device

The invention discloses an insulation device for a tower crane working near an electromagnetic wave source and a construction method of the insulation device. The insulation device comprises a hook mechanism connected with a tower crane arm through a roller and an insulation hoisting mechanism connected with the hook mechanism; the insulation hoisting mechanism is movably connected with a steel wire rope through a hoisting ring and hoists building materials; and the insulation hoisting mechanism comprises a hoisting belt made of insulation materials. The insulation device can be widely applied to the tower crane working near the strong electromagnetic wave source, and compared with a traditional steel wire rope grounding discharge technology, the service life of the steel wire rope is prolonged; the problem about the discharge time of a hook and the steel wire rope is solved, and the field production efficiency is improved; induced voltage can be effectively eliminated, electric shock of the human body is pre
