Description

Power transmission and transformation line wire fixing device

Technical field:

The utility model relates to a fixing device, in particular to a fixing device for electric wires of power transmission and transformation lines, and belongs to the technical field of wire maintenance equipment for electric power grids.

Background technique:

At present, the entry line of the grid line is relatively long, and the entry line will sag under the action of gravity, which brings unsafe factors and also affects the normal operation of the line. At present, four-core strain-resistant clamps are generally used to erect multiple incoming lines. However, due to the complex structure of the four-core strain-resistant clamps, installation is inconvenient, maintenance and replacement are difficult, and the cost is high.

Utility model content:

The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art, and provide a wire fixing device for power transmission and transformation lines, which has a simple structure, convenient installation and low production cost.

The technical scheme that the utility model takes for solving the technical problem is:

A wire fixing device for power transmission and transformation lines, comprising a fixing plate, the fixing plate includes an upper fixing plate and a lower fixing plate, the lower end of the upper fixing plate is provided with an upper groove, and the upper end of the lower fixing plate is provided with a lower groove ; At the center position of the lower fixing plate, a central screw hole that runs through the lower fixing plate is provided, and a lead screw is arranged in the center screw hole, and the upper end of the lead screw is provided with a wire briquetting block, and the lower end of the lead screw passes through the center The screw hole is fixed together with the lower fixing plate by a nut.

The upper end surface of the electric wire pressing block is an arc-shaped groove, and the arc-shaped groove matches the upper groove.

Four corners of the fixing plate are provided with bolt holes, and the fixing plate is fixed with the wall through expansion bolts passing through the bolt holes.

The positive beneficial effects of the utility model are as follows:

1. The utility model is provided with a central screw hole penetrating the lower fixed plate at the center of the lower fixed plate, and a lead screw is arranged in the center screw hole, and a wire pressing block is arranged at the upper end of the lead screw. By rotating the lead screw, the wire can be The pressing block moves up and down, which is convenient for clamping or removing the incoming wires. It is easy to install and saves time and effort.

2. The utility model arranges a wire pressing block at the upper end of the lead screw, and the arc groove of the wire pressing block matches the upper groove at the lower end of the upper fixing plate, so that the wire is more firmly pressed in the groove to prevent movement or fall off.

3. The utility model is provided with bolt holes at the four corners of the fixing plate, and the fixing plate is fixed with the wall through the expansion bolts passing through the bolt holes, which has good economical and practical effects.

4. The utility model has the advantages of simple structure, convenient installation, low production cost, great practical value and market promotion prospect.

Detailed ways:

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

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further explained and illustrated:

Referring to Fig. 1 , a power transmission line wire fixing device includes a fixed plate 2, the fixed plate 2 includes an upper fixed plate 1 and a lower fixed plate 10, an upper groove 3 is arranged at the lower end of the upper fixed plate 1, and an upper groove 3 is arranged on the lower fixed plate 10. The upper end is provided with a lower groove 4, and the center position of the lower fixing plate 10 is provided with a central screw hole 11 passing through the lower fixing plate 10, and a lead screw 6 is arranged in the center screw hole 11, and a wire pressing block is arranged at the upper end of the lead screw 6 5. The upper end surface of the wire pressing block 5 is an arc groove, which matches the upper groove 3; the lower end of the lead screw 6 passes through the central screw hole 11 and is fixed together with the lower fixing plate 10 through the nut 7; Four corners of the fixing plate 2 are provided with bolt holes 8 , and the fixing plate 2 is fixed with the wall through expansion bolts 9 passing through the bolt holes 8 .

Because the utility model is provided with the center screw hole 11 that runs through the lower fixing plate at the central position of the lower fixing plate 10, a lead screw 6 is arranged in the center screw hole 11, and a wire pressing block 5 is arranged on the upper end of the lead screw 6. By rotating the lead screw 6. The wire pressing block 5 can be moved up and down, which is convenient for clamping or removing the incoming wires, which is convenient for installation and saves time and effort.
