Description

EYE SHACKLE DEVICE AND ADJUSTING METHOD OF DIP USING THE SAME}

The present invention relates to an eye shackle device and a method for adjusting the degree of distribution of an overhead power line using the same, and more particularly, to an eye shackle device for adjusting the degree of distribution of an electric wire and a method for adjusting the degree of distribution of an overhead power line using the same.

In general, in distribution overhead lines, wires are wired loosely. Dip is a concept that refers to the difference between the horizontal line connecting the support point of the wire and the lowest part of the wire, that is, the degree of sagging of the wire. The smaller the ear canal, the higher the tensile force applied to the wire, making it easier to damage the wire.

Therefore, when wiring wires in overhead power lines, it is important to set the ear canal to an appropriate value, and the wires on overhead power lines not only have different locations, heights, directions of extension, and lengths, but also vary in the surrounding structures and natural environmental conditions. They are all different, so they are set appropriately by considering and applying different conditions.

In the existing wiring of wires, after pulling the wire to the pole side to the desired ear canal range in the state of gripping the wire using a long wire, the wire is bound to the clamp, and the tensile load of the wire wire is released. However, a situation in which the ear canal actually increases beyond the intended range of the ear canal frequently occurs as deflection additionally occurs due to the load of the electric wire after the tensile load of the lengthening machine is released.

In the case of further pulling the wire using a long wire to meet the condition of the wire, since a higher load is directly and repeatedly applied to the wire, there is a problem that there is a high risk of damage to the wire. In addition, in consideration of the additional sagging of the wire after releasing the tensile load of the joist, it is possible to use the joist to pull the wire in advance, but in reality, the degree of additional deflection of the wire in each section is different. Therefore, there was a problem that it was difficult to set the standard for the degree of pulling in advance.

Therefore, there is a need to improve this.
