Description

A labor-saving wire lifter for mountainous terrain

technical field

The invention relates to a line lifter, in particular to a labor-saving line lifter for mountainous areas.

Background technique

At present, in areas dominated by mountainous areas, the distribution lines tend to have too large spans and large wire diameters due to narrow passages. And the linear rod of the line is the most rod type in the power distribution line. The distribution line is different from the straight tower hanging bottle used in the transmission line, but the porcelain rod is used for hanging, so due to the large diameter of the line wire , The distance is too large and the weight is heavy, which causes a lot of pressure on the porcelain rod of the straight rod and is easy to break in the finished porcelain rod. In addition, lightning strikes or external force can easily cause the porcelain rod to break, and the wires may fall off from time to time.

In addition, when replacing or maintaining the wires in the line transformation, the existing structure is extremely laborious and time-consuming to lift the wires. In addition, the mountainous area is not suitable for construction, and the original method is still used to lift the wires to the crossarm only by people. This method Laborious and unsafe.

The connecting rods of the thread lifters suitable for mountain roads disclosed in the prior art are all in the shape of an "L", which leads to different strengths used when carrying out the thread lifting operation at different angles, which greatly wastes effort.

By improving the structure of the connecting rod, the present invention improves the original overall structure into a hinged mode of the main rod and the installation rod, and connects the setting of the middle part of the adjustment dish and the installation rod through the connection rope. When the position changes, the hinge angle between the main rod and the installation rod can be effectively adjusted, thereby effectively changing the angle of the wire rope and saving the labor of the operator when lifting the wire.

Further, in order to improve the service life of the connecting rope and save the labor when changing the position between the connecting rod and the adjustment of the hair plate, a pulley is provided inside the main rod and inside the installation rod to facilitate the movement of the connecting rope.

Furthermore, the pulley block is composed of a movable pulley and a fixed pulley, the movable pulley is suspended at one end of the wire rope and used to fix the hook; the fixed pulley is fixedly installed on the installation rod.

In order to achieve a more stable connection, the main rod is fixedly installed on the U-shaped ring through the connecting plate, wherein the connecting plate is provided with a horizontal strip-shaped mounting hole, and the bottom of the main rod is fixed by the first fixing bolt On the bar-shaped mounting hole, the rod body on the main rod that is close to the adjustment hair plate is fixed on the adjustment hole by the third fixing bolt.

In order to achieve a better fixing effect, the U-shaped ring is fixed on the cross arm of the utility pole through the second fixing bolt.

Compared with the prior art, the present invention has the following advantages and beneficial effects:

1. The present invention can effectively adjust the hinge angle between the main rod and the installation rod, thereby effectively changing the angle of the wire rope, saving the labor of the operator when lifting the wire, and achieving the purpose of saving time and effort;

2. The interior of the main rod and the installation rod of the present invention are respectively provided with a pulley for the movement of the connecting rope, which not only improves the service life of the connecting rope, but also saves the time spent on changing the position between the connecting rod and the adjustment of the hair plate. Labor force, to further achieve the purpose of saving time and effort;

3. The present invention has the advantages of simple structure and less labor-saving operation.
