technical field

The utility model relates to a steering and grounding device for power transmission overhead lines, in particular to a steering and grounding device for 35kV~110kV power transmission overhead lines used for on-site power failure maintenance.

Background technique

In the prior art, most of the crossarms of the transmission line tension towers are perpendicular to the wires, but the current grounding wires can only be used when the grounding rod held by the maintenance personnel is perpendicular to or close to the vertical wires. Therefore, when hanging the grounding wire on the tension tower, it is difficult for the maintenance personnel to hang the grounding wire on the wire outside the tension tower insulator clamp. This greatly reduces the efficiency of power outage maintenance, and it is urgent to develop a grounding wire that can realize the function of turning to the grounding to solve the problem of hanging the grounding wire on the wire outside the tension pole insulator clamp of the transmission line.

Detailed ways

Below the utility model will be further described in conjunction with the embodiment in the accompanying drawing:

As shown in Figures 1 to 2, the utility model mainly includes a wire clamp main body 1, a screw rod 5 and an insulating operating rod 8. The upper part of the wire clamp main body 1 is provided with a wire clamp hook 2 integrated with the wire clamp main body 1. The wire clamp hook 2 is provided with an inverted U-shaped opening.

The middle part of the main body 1 of the wire clamp is slidably connected to the wire clamp pressing plate 3, and the upper end of the wire clamp pressing plate 3 is provided with a U-shaped opening. The U-shaped opening on the wire clamp pressing plate 3 and the inverted U-shaped opening in the wire clamp hook 2 form a bayonet for clamping the wire.

The screw rod 5 connects the lower part of the wire clamp main body 1 and the wire clamp pressing plate 3 through the bearings at both ends, and the second helical bevel gear 7 is installed on the screw rod 5 .

The lower part of the clamp main body 1 is fixed with a connecting bracket 4 , the connecting bracket 4 is connected with an insulating operating rod 8 , and the first helical bevel gear 6 is installed on the insulating operating rod 8 . The first helical bevel gear 6 and the second helical bevel gear 7 located in the connecting bracket 4 are engaged with each other, and the first helical bevel gear 6 and the second helical bevel gear 7 are perpendicular to each other.

The working principle of the utility model is: when grounding is required, the rotation of the insulating operating rod 8 drives the first helical bevel gear 6 to rotate, and the first helical bevel gear 6 drives the second helical bevel gear 7 meshing with it to rotate. The second helical bevel gear 7 drives the screw rod 5 to move upward. The screw rod 5 then drives the line clamping plate 3 to clamp the power transmission overhead line. At the same time, the grounding end is connected to the main body 1 of the clamp through the copper wire, so as to ground the power transmission overhead line. On the contrary, the operation is to loosen the grounding of the transmission overhead line. The utility model has a simple, compact and reasonable structure, and has better portability; it has a 90° right-angle steering function, is easy to use, can reduce the labor intensity of staff, and improves the efficiency of hanging the ground wire.
