전력선 인출용 풀링아이{Pulling eye for extracting power line}Pulling eye for extracting power line

본 발명은 전력선 인출용 풀링아이에 관한 것으로서, 보다 상세하게는 가로등과 같은 시설물을 설치할 때 콘크리트 매설물 내의 매설관과 시설물 사이의 지중에 매설된 보호관을 통하여 전력선을 견인함에 있어서 인장와이어나 전력선을 피복된 채로 간단하게 고정시킬 수 있고, 매설관과 지중의 보호관을 통과할 때 사방으로 탄성설치된 판스프링 외측면에 축고정되어 회동되는 롤러에 의해 발생하는 마찰이나 회전 등으로 인해 결속이 해제되거나 인장와이어가 끊어질 염려가 없는 전력선 인출용 풀링아이에 관한 것이다. The present invention relates to a pulling eye for pulling out a power line, and more particularly, when a facility such as a street lamp is installed, a tension wire or a power line is covered in towing the power line through a protective tube embedded in the ground between the buried pipe in the concrete buried facility and the facility. It can be easily fixed while the binding is released or the tension wire is caused by friction or rotation generated by the roller which is pivoted on the outer surface of the leaf spring that is elastically installed in all directions when passing through the buried pipe and the protective pipe of the underground. The present invention relates to a pulling eye for pulling out power lines without fear of breaking.

일반적으로 풀링아이(Pulling eye)는 전력선 종단에서 인장와이어와 포설장비를 연결하여 포설작업을 실시할 때 전력선 당기는 것을 용이하게 하고, 규정 포설장력 이상으로 당길 경우에도 전력선 인장와이어에 영향을 미치지 않도록 하여 전력선의 외피가 손상되거나 인장와이어가 늘어나면서 단선되는 것을 방지하기 위하여 사용되는 것이다.In general, the pulling eye connects the tension wire and the installation equipment at the end of the power line to facilitate pulling the power line when laying, and does not affect the power line tension wire even when pulling over the specified laying tension. It is used to prevent the breakage of the outer line of the power line or the disconnection of the tension wire.

가로등을 설치하는 경우와 같이, 전력선 중간 중간에 전력을 사용하는 시설물을 설치할 경우에는, 양측의 콘크리트 매설물 내에 삽입되어 있는 매설관 및 그 사이의 지중에 매설되어 있는 보호관을 통하여 전력선을 분배해야 하는데, 종래에는 인장와이어를 매설관과 보호관을 통과시킨 후, 일측에서 상기 인장와이어를 전력선에 묶은 다음, 타측에서 인장와이어를 당기는 방법에 의해서 전력선을 분배하였다.When installing a facility that uses electric power in the middle of a power line, such as when installing a street lamp, power lines must be distributed through buried pipes inserted in concrete buried on both sides and protection pipes embedded in the ground between them. Conventionally, after passing the tension wire through the buried pipe and the protective tube, the power wire is distributed by tying the tension wire to the power line on one side and pulling the tension wire on the other side.

이러한 방법은 전력선을 묶는 부위의 피복을 벗겨내는바, 이는 인장와이어로 묶은 부위의 부피를 작게 하여서 보호관과 매설관 속을 통과하기 쉽게 하기 위한 것이다.This method strips off the sheathing of the area enclosing the power line, so that the volume of the area enclosed by the tension wire is made small so that it can easily pass through the protective tube and the buried line.

그러나, 이와 같은 종래의 방법은 전력선의 피복을 벗긴 후 작업을 하므로 작업과정이 번거로울 뿐만 아니라, 그 결속력이 약해서 매설관을 통과할 때 주위벽과의 마찰이나 돌출부위에의 걸림에 의하여 인장와이어의 결속이 풀어지게 되어 처음부터 다시 작업을 해야 하는 번거로운 문제점이 있었다.However, this conventional method is not only cumbersome because the work is performed after removing the covering of the power line, but also because the binding force is weak, the binding of the tension wire by the friction with the surrounding wall or the engagement on the protruding part when passing through the buried pipe There was a cumbersome problem that was to be released from the beginning to work again.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 가로등과 같은 시설물을 설치할 때 콘크리트 매설물 내의 매설관과 시설물 사이의 지중에 매설된 보호관을 통하여 전력선을 견인함에 있어서 인장와이어나 전력선을 피복된 채로 간단하게 고정시킬 수 있고, 매설관과 지중의 보호관을 통과할 때 사방으로 탄성설치된 판스프링 외측면에 축고정되어 회동되는 롤러에 의해 발생하는 마찰이나 회전 등으로 인해 결속이 해제되거나 인장와이어가 끊어질 염려가 없는 전력선 인출용 풀링아이를 제공함에 그 목적이 있다.The present invention is to solve the above problems, when installing the facility, such as street lamps, to pull the power line through the protective pipe buried in the ground between the buried pipe and the facility in the concrete buried in the tension wire or power line simply covered with When passing through the buried pipe and the underground protective pipe, the binding is released or the tension wire is broken due to friction or rotation generated by the roller which is axially fixed to the outer surface of the leaf spring that is elastically installed in all directions. An object of the present invention is to provide a pulling eye for pulling out power lines without concern.
