The invention discloses a special grounding device for a pole without guys, and mainly relates to the field of power equipment. The special grounding device includes grounding blocks, grounding pipes,grounding wires and wire feeding device assemblies. Each wire feeding device assembly includes a placing frame, a device housing, a ratchet mechanism, a wire feeding mechanism and a wire feeding cord; a cross arm clamping groove is arranged between the placing frame and the device housing; the wire feeding mechanism includes a driving wire feeding wheel and a driven wire feeding wheel; the wire feeding cord passes through a gap between the driving wire feeding wheel and the driven wire feeding wheel; the height of the gap between the driving wire feeding wheel and the driven wire feeding wheel is 0.75 to 0.9 times of the diameter of the wire feeding cord; and a connecting device end of the grounding wire is detachably arranged on the wire feeding cord. The beneficial effect of the specialgrounding device in the invention lies in that by providing the grounding pipes, the grounding ends are connected with the grounding blocks at the bottom of the pole without guys, and the purpose ofgrounding is achieved; furthermore, the grounding wires can be conveniently transported from the ground to iron cross arms; and the connection is more secure when the grounding wires hang in the air.
