The present invention relates to a near-cost installation device for electric poles, and more particularly, to a near-cost installation device for electric poles that is used when installing a near-cost installation that is buried in the ground in a bonded state with the electric pole when installing the electric pole.

In general, when installing electric poles used to construct power lines, if the ground is soft, a base is installed near where the electric pole is buried to prevent the electric pole from tilting.

In this case, the root price used for the electric pole is used by using an arch, semicircle, and straight shape depending on the shape.

Accordingly, looking at the construction method of electric poles using the conventional root cost, Korean Patent Registration No. 10-0777688 (Announcement on November 19, 2007), which is Patent Document 1, shows a pole for an overhead line and a pole for an overhead line and a pole that is buried and concluded in the lower part of the pole. Wow, the auger hook for transporting and installing the above-mentioned electric pole, a U bolt for combining the electric pole and the electric pole, an auger crane device for moving the electric pole and the electric pole, and an extension type that is installed and used in the auger crane. An arch-type electric pole construction method for overhead lines using an extended excavation unit for auger cranes that conducts construction work through sequential execution of the work process and work steps systematically by the excavation unit is disclosed.

Patent Document 1 like this allows the construction of electric poles for overhead lines to be carried out quickly and stably with only auger crane, while the grounding work using arched electric poles having a grounding function as well as the solid installation work of the electric poles with an arched electric pole It is easy, and the construction period is shortened because the excavation of the buried hole is conveniently and quickly performed without the additional excavation process by inputting additional manpower or equipment for the burying near the Jeonju by using the expandable excavation unit that can be expanded and restored to its original state. Of course, it provides advantages with excellent economic effects such as reduction of construction cost, improvement of workplace environment and improvement of construction quality.

Here, in Patent Literature 1, in order to combine the root price with the electric pole during the construction of the electric pole, the work of lifting the root price with a crane must be performed, but in order to lift the root price, the work of lifting the root price with a hook must be performed.

In this case, looking at the shape of the conventionally used hook, Korean Patent No. 10-0923500 (announced on October 27, 2009) of Patent Document 2 includes a bent body formed of a horizontal portion and a vertical portion; It consists of a rotating body with a hook part spaced apart from both sides and a mounting part connecting the hook parts, and a hinge hole is formed in the horizontal part of the fixture, and a fixed shaft rod protrudes from the lower part of the vertical part. A hook hole is formed at the distal end of the hook portion, and a hinge-type hook for transporting a frontal muscle that fixes a hinge axis between the hook portions is disclosed.

Similar to Patent Document 2, Korean Patent No. 10-0797415, which is Patent Document 3, includes a hook for hanging on a hook of a crane, a fixture positioned at the lower side of the hook to hold the level of the front pole, and the front pole.

Therefore, in the case of a conventional hook for a near price, even when the center of gravity changes during transport of a damaged area to be bound, a technical solution is needed to maintain the coupling force with the root price.

In addition, near-end hooks such as Patent Document 2 and Patent Document 3 are manufactured in a specific standard, and there is a difference in specifications for each manufacturer, and the shape is also varied in arch shape, semicircular shape, and straight shape, as described above.

Accordingly, conventional hooks for near prices are custom-made for near prices of a specific standard, and the types of near prices are very diverse as described above, and errors occur for each manufacturer.

In this case, in the case of raising the cost of another company by using a hook for the price produced and used by a specific company due to an error caused by the difference in specifications for each manufacturer, the exact price is not settled due to the difference in specifications. There is a problem that it causes a safety accident in which it is rotated in the middle of transport without being in a state, and at this time, the laborer is dropped from the hook for laborer.

Therefore, the conventional hook for near price requires a technical solution that provides a solid fastening force so as not to drop out of the near price even when the standard of the near price is different for each manufacturer and an error is formed.
