Abstract
The invention relates to a power transmission overhead line steering grounding device, in particular to a 35kV-110kV power transmission overhead line steering grounding device used for on-site power transmission line blackout overhaul. The power transmission overhead line steering grounding device comprises a line clamp body, a threaded rod and an insulating operating rod. A line clamp hook integrally connected with the line clamp body is arranged on the upper portion of the line clamp body, and the middle of the line clamp body is connected with a line clamp pressing plate in a sliding mode. The threaded rod is connected with the lower portion of the line clamp body and the line clamp pressing plate through bearings at two ends and is provided with a second helical bevel gear. A connecting support is fixed on the lower portion of the line clamp body and connected with the insulating operating rod which is provided with a first helical bevel gear. The first helical bevel gear located in the connecting support is connected with the second helical bevel gear in a meshing mode. The power transmission overhead line steering grounding device has good portability, has a function of right angle steering, is easy and convenient to use, can lighten labor intensity of staff, and improves hanging ground lead efficiency.
Description
Technical field
The present invention relates to a kind of transmission overhead line and turn to earthing device, a kind of 35kV for on-the-spot transmission line interruption maintenance ~ 110kV transmission overhead line turns to earthing device specifically.
Background technology
The cross-arm major part of power line tension shaft tower all is perpendicular with wire in the prior art, and present earth connection, it is vertical with wire or earth connection could be suspended on the wire when vertical to be applicable to the earth rod handed as the maintainer, therefore carrying out strain rod tower when hanging earth connection, the maintenance people is difficult to earth connection is suspended on the wire in the strain rod tower insulator wire clamp outside.This is so that interruption maintenance efficient reduces greatly, and the urgent need development is a kind of can to realize turning to the earth connection of grounding function to solve a difficult problem that hangs earth connection at the wire in the power line tension shaft tower insulator wire clamp outside.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby provide a kind of transmission overhead line with 90 ° of right-angle steering functions to turn to earthing device, the applicability of energy Effective Raise earth connection shortens the earth connection time that hangs, and improves transmission line interruption maintenance operating efficiency.
According to technical scheme provided by the invention, transmission overhead line turns to earthing device to comprise wire clamp main body, screw rod and insulating bar, it is characterized in that: wire clamp main body top is provided with the wire clamp hook that links into an integrated entity with the wire clamp main body, and the wire clamp pressing plate is slidingly connected in the middle part of the wire clamp main body.Screw rod is installed the second helical bevel gear by bearing connecting clamp lower body part and the wire clamp pressing plate at two ends on the screw rod.The wire clamp lower body part is fixedly connected with support, connects insulating bar on the connection bracket, and the first helical bevel gear is installed on the insulating bar.The first helical bevel gear that is positioned at connection bracket be connected the helical bevel gear connection of intermeshing.
Further, be provided with inverted U-shaped opening in the wire clamp hook.
Further, wire clamp pressing plate upper end is provided with the U-shaped opening.
Further, the first helical bevel gear and the second helical bevel gear are orthogonal.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable, has portable preferably; Have 90 ° of right-angle steering functions, easy to use, the labour intensity that can reduce a staff, raising hangs earth connection efficient.

Description of reference numerals: 1-wire clamp main body, 2-wire clamp hook, 3-wire clamp pressing plate, 4-connection bracket, 5-screw rod, 6-the first helical bevel gear, 7-the second helical bevel gear, 8-insulating bar.
Embodiment
Following the present invention is further described in connection with the embodiment in the accompanying drawing:
Shown in Fig. 1 ~ 2, the present invention mainly comprises wire clamp main body 1, screw rod 5 and insulating bar 8, and wire clamp main body 1 top is provided with the wire clamp hook 2 that links into an integrated entity with wire clamp main body 1, is provided with inverted U-shaped opening in the wire clamp hook 2.
The wire clamp main body 1 middle part wire clamp pressing plate 3 that is slidingly connected, wire clamp pressing plate 3 upper ends are provided with the U-shaped opening.Inverted U-shaped opening in U-shaped opening on the wire clamp pressing plate 3 and the wire clamp hook 2 forms the bayonet socket of a clamping wire.
Wire clamp main body 1 bottom is fixedly connected with support 4, connects insulating bar 8 on the connection bracket 4, and the first helical bevel gear 6 is installed on the insulating bar 8.The first helical bevel gear 6 that is positioned at connection bracket 4 be connected helical bevel gear 7 connection of intermeshing, the first helical bevel gear 6 and the second helical bevel gear 7 are orthogonal.
Operation principle of the present invention is: when needs ground connection, rotate insulating bar 8 and drive 6 rotations of the first helical bevel gear, the first helical bevel gear 6 drives again the second helical bevel gear 7 that is engaged with and rotates, and the second helical bevel gear 7 drives screw rods 5 and moves upward.Screw rod 5 drives wire clamp pressing plate 3 thereupon transmission overhead line is clamped.Simultaneously, earth terminal is by copper cash connecting clamp main body 1, thus so that transmission overhead line ground connection.Otherwise transmission overhead line ground connection is then unclamped in operation.The present invention is simple in structure, compact, reasonable, has portable preferably; Have 90 ° of right-angle steering functions, easy to use, the labour intensity that can reduce a staff, raising hangs earth connection efficient.
