At present, two types of commonly used grounding wires in the power failure maintenance work of the power transmission line are a rod type grounding wire and a throwing hanging type grounding wire. The pole-type earth connection is often used in the low voltage line, and after the operation personnel fixed the ground clamp on the shaft tower, handheld insulating bar will connect the electric clamp card on the wire, will connect the electric clamp to withdraw through the action bars after the operation.

The throwing-hanging type grounding wire is commonly used for tangent towers and tension towers with large distance between cross arms and leads or difficult steering of rod type grounding wires, the grounding clamp needs to be fixed firstly when the grounding wire is used, an operator puts down an insulating rope, loosens the grounding clamp after the power connection clamp is arranged above the leads, falls down and clamps the leads by gravity, and the power connection clamp is withdrawn by pulling up the rope after the operation is finished.

However, at present, bird-proof baffles are generally arranged above insulator hanging points of the power transmission line, and when the grounding wire is installed, an operator cannot directly reach the position right above the line hanging points. The anti-bird sheath is also equipped with to the point of hanging under the insulator, uses the throwing hanging earth connection and needs the operation personnel to rock the rope repeatedly, installs the degree of difficulty very big. Even if the hanging is successful, the risk that the power connection clamp falls off can also exist due to non-vertical clamping. The rod-type grounding wire also has the problems of insufficient length, inconvenience in carrying, incapability of changing directions at special angles and the like.

The utility model relates to a ground wire hanging device with a turnable power connection clamp and an extendable operating rod, which solves the problem that ground wires cannot be hung in various environments.
