Special grounding device for pole without guys

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a special grounding device for no pull rod. Background technique [0002] In electric power construction work, the traditional non-pull pole does not have a special grounding device. If the grounding wire needs to be suspended on the terminal pole in electric power construction work, it is necessary to use the grounding wire of the lightning arrester as an auxiliary grounding wire. The grounding wire of the lightning arrester is usually relatively thin. , The crimping process is not reliable enough, resulting in unreliable grounding and potential safety hazards. If the suspended grounding wire is connected to the grounding block at the bottom of the non-staying rod to achieve the purpose of grounding, there are the following defects: [0003] 1. The grounding block is buried deep underground, so that the grounding end of the grounding wire cannot be connected to the g...

Problems solved by technology

When raising the grounding wire to the top without a pull rod, the construction personnel need to fix the ground wire at the waist, and then climb to the iron cross arm without a pull rod to connect the equipment end of the ground wire with the terminal rod. This process is extremely difficult. The earth consumed the physical strength of the
