The invention discloses a guide device for enabling an unmanned gyroplane to automatically get on and off a production line for insulating operation. The guide device comprises a flying equipment cabin, wherein six rotor wing arms are mounted on the outer side face of the flying equipment cabin at equal distances; a flying motor is fixedly mounted at one end, away from the flying equipment cabin, of each rotor wing arm; rotor wings are connected to rotating shafts of the flying motors in a sleeving manner; a 24GHZ radar sensor and two insulating supporting rods are fixedly mounted on the upper surface of the flying equipment cabin; the two insulating supporting rods are horizontally arranged on the rear side of the 24GHZ radar sensor. According to the guide device and a method for enabling the unmanned gyroplane to automatically get on and off the production line for insulating operation, under the synergistic effect of multiple modules such as radar detection and GPS, a distance between the unmanned geroplane and an overhead line can be detected and calculated, so that the unmanned geroplane can fall off the line precisely and safely in an insulated manner, a foundation is laid for automatically getting on and off the production line during routing inspection, technical optimization is carried out to avoid obstacles, and the labor cost and the accident risk are greatly reduced.
