Description

Transmission line overhead ground wire lifter

technical field

The utility model belongs to the technical field of transmission line construction equipment, in particular to an overhead ground wire lifter for transmission lines.

Background technique

Transmission line: It is a power line with a voltage level of 35kV and above connecting the power plant and the substation and between the substations. Overhead ground wire (also known as lightning protection wire): it is set above the power transmission wire to prevent the wire from being directly struck by lightning. Important transmission lines usually use two overhead ground wires.

With the increase of railway reconstruction, afforestation, urban planning and other projects, transmission lines often need to re-erect towers or increase towers. At the same time, when new overhead transmission lines are built, the main difficulty in the installation of overhead ground wires lies in the lifting of the ground wires. , due to the small cross arm on the top of the tower, it is not easy to carry out various tasks, so a convenient and professional tool is needed to carry out this work.

Description of drawings

Fig. 1 is a structural representation of the utility model;

In the figure: 1-fixture, 2-U-shaped groove, 3-fixture, 4-first fastening nut, 5-second fastening nut, 6-screw rod, 7-hook, 8-lifting nut, 9- handle.

Detailed ways

As shown in Figure 1, the overhead ground wire lifter for transmission lines includes clamp 1, clamp 2, first fastening nut 4, second fastening nut 5, screw rod 6, lifting nut 8, handle 9, clamp 1 is provided with a U-shaped groove 2, and the notch of the U-shaped groove 2 faces downward. The clamp 1 is provided with a first hole and a second hole. The U-shaped groove 2 is located between the first hole and the second hole. The clamp 2 U-shaped, the two ends of the fixture 2 are respectively provided with external threads, one end of the fixture 2 passes through the first hole from bottom to top, and then the first fastening nut 4 is screwed on, and the other end of the fixture 2 passes from bottom to top Screw on the second fastening nut 5 after the second hole; One end of the jig 1 is provided with a lifting hole, and the lower end of the screw mandrel 6 is provided with a hook 7, and the upper end of the screw mandrel 6 passes through the lifting hole from bottom to top and spins back. Go up lifting nut 8 (constitute screw mandrel pair), one end of handle 9 is hinged with lifting nut 8.

Operation of ground wire installation:

1. Clamp the clamp on the cross arm of the ground wire (the cross arm is located between the clamp 1 and the U-shaped clamp 3), and tighten the first fastening nut 4 and the second fastening nut 5;

2. Rotate the handle 9, adjust the length of the screw rod 6 so that the hook 7 hooks the overhead ground wire;

3. Turn the handle, the screw rod rises, and the overhead ground wire (also known as the lightning protection wire) is lifted.

This power transmission line overhead ground wire lifter is easy to use and can easily complete the lifting work of the ground wire.
