Description

Transmission overhead line turns to earthing device
Technical field
The utility model relates to a kind of transmission overhead line and turns to earthing device, and a kind of 35kV for on-the-spot transmission line interruption maintenance ~ 110kV transmission overhead line turns to earthing device specifically.
Background technology
In prior art, the cross-arm major part of power line tension shaft tower is all perpendicular with wire, and current earth connection, can only be applicable to when the hand-held earth rod of maintainer is vertical with wire or approach when vertical and earth connection could be suspended on wire, therefore carrying out strain rod tower while 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 makes interruption maintenance efficiency greatly reduce, and the urgent need development is a kind of can realize turning to the earth connection of grounding function to solve a difficult problem that hangs earth connection on the wire in the power line tension shaft tower insulator wire clamp outside.
Summary of the invention
The purpose of this utility model 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, can effectively improve the applicability of earth connection, shorten the earth connection time that hangs, improve transmission line interruption maintenance operating efficiency.
The technical scheme provided according to the utility model, 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 linked into an integrated entity with the wire clamp main body, and the wire clamp pressing plate is slidably connected in the middle part of the wire clamp main body.Screw rod, by bearing connecting clamp lower body part and the wire clamp pressing plate at two ends, is installed the second helical bevel gear on screw rod.The wire clamp lower body part is fixedly connected with support, connects insulating bar on connection bracket, and the first helical bevel gear is installed on insulating bar.The first helical bevel gear that is positioned at connection bracket intermeshes and is connected with the second helical bevel gear.
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 utility model has the following advantages:
The utility model 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, improve and hang earth connection efficiency.
The accompanying drawing explanation
Fig. 1 is the utility model front view.
Fig. 2 is the utility model end view.
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 utility model is further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1 and 2, the utility model 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 linked into an integrated entity with wire clamp main body 1, in wire clamp hook 2, is provided with inverted U-shaped opening.
The wire clamp main body 1 middle part wire clamp pressing plate 3 that is slidably connected, wire clamp pressing plate 3 upper ends are provided with the U-shaped opening.Inverted U-shaped opening in U-shaped opening on wire clamp pressing plate 3 and wire clamp hook 2 forms the bayonet socket of a clamping wire.
Screw rod 5, by bearing connecting clamp main body 1 bottom and the wire clamp pressing plate 3 at two ends, is installed the second helical bevel gear 7 on screw rod 5.
Wire clamp main body 1 bottom is fixedly connected with support 4, connects insulating bar 8 on connection bracket 4, and the first helical bevel gear 6 is installed on insulating bar 8.The first helical bevel gear 6 that is positioned at connection bracket 4 intermeshes and is connected with the second helical bevel gear 7, and the first helical bevel gear 6 and the second helical bevel gear 7 are orthogonal.
Operation principle of the present utility model is: when needs ground connection, rotate insulating bar 8 and drive the first helical bevel gear 6 rotations, the first helical bevel gear 6 drives again the second helical bevel gear 7 be engaged with and rotates, and the second helical bevel gear 7 drives screw rod 5 and moves upward.Screw rod 5 drives wire clamp pressing plate 3 thereupon transmission overhead line is clamped.Simultaneously, earth terminal passes through copper cash connecting clamp main body 1, thereby makes transmission overhead line ground connection.Otherwise transmission overhead line ground connection is unclamped in operation.The utility model 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, improve and hang earth connection efficiency.
