본 발명은 지하관로에 수용되어 있는 동케이블을 철거하기 위한 장치에 관한 것이다. 더욱 상세하게 본 발명은 동케이블의 용이한 철거를 위해 동케이블에 체결되는 철거용 지그에 관한 것이다.The present invention relates to a device for dismantling a copper cable housed in an underground pipeline. More specifically, the present invention relates to a jig for dismantling fastened to a copper cable for easy dismantling of the copper cable.

통상 지하 통신관로에 수용되어 있는 동케이블을 철거하는 경우 지상과는 달리 좁은 맨홀 내에서 작업이 이루어짐으로 작업환경이 열악하고 철거를 위한 장치가 전무하여 작업에 어려운 점이 있었다.In general, when the copper cable housed in the underground communication channel is to be dismantled, unlike in the ground, the work is performed in a narrow manhole, and thus the working environment is poor and there is no device for dismantling.

종래의 동케이블 철거 구조를 살펴보면, 작업자가 맨홀 내의 동케이블 선단에 동케이블을 견인하기 위한 와이어를 묶고 외부 동력원을 이용하여 와이어를 당김으로서 동케이블을 인출하였다.Looking at the conventional copper cable dismantling structure, the operator tied the wire for pulling the copper cable to the copper cable tip in the manhole and pulled the copper cable by pulling the wire using an external power source.

그러나 상기한 종래의 구조는 맨홀 내의 좁은 공간에서 작업자가 동케이블 선단에 와이어를 단단히 체결해야 하는 작업상의 어려움이 있다.However, the above-described conventional structure has a problem in that an operator must fasten a wire to the end of a copper cable in a narrow space in a manhole.

또한, 종래의 구조는 와이어로 동케이블을 꽉 묶었다 하더라도 PE 재질의 외피와 구리 재질의 심선나 윤활제인 젤리 등 복합재료로 구성되어 재료들의 변형이 심한 동케이블을 충분한 견인력으로 묶기 힘들어 와이어가 동케이블의 표면에서 미끄러지는 현상이 발생되고 이에 따라 견인력을 충분히 가할 수 없다는 단점이 있다.In addition, even if the copper cable is tightly bound with wire, the conventional structure is composed of a composite material such as PE sheath and copper core wire or jelly, which is a lubricant. Sliding occurs on the surface of the cable, and there is a drawback in that it cannot apply traction sufficiently.

또한, 종래의 구조는 와이어가 동케이블을 전체적으로 끌어당기지 못하고 외피만을 잡아당기게 되어 동케이블의 외피가 찢어지면서 내부 심선과 외피가 분리되는 문제점이 발생된다.In addition, the conventional structure is that the wire does not pull the copper cable as a whole pulls only the outer sheath is a problem that the inner core wire and the outer shell is separated as the outer sheath of the copper cable is torn.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 동케이블에에 와이어를 용이하게 걸 수 있도록 된 동케이블 철거용 지그를 제공함에 있다.The present invention has been made to solve the above problems, an object of the present invention to provide a jig for copper cable demolition that can be easily hooked to the copper cable.

또한, 본 발명은 동케이블 표면에 견고히 설치되어 동케이블의 외피는 물론 내부 심선까지 충분히 견인할 수 있도록 된 동케이블 철거용 지그를 제공함에 또다른 목적이 있다.In addition, the present invention is another object to provide a jig for demolition of the copper cable that is firmly installed on the surface of the copper cable so as to be able to sufficiently pull the outer core as well as the inner core of the copper cable.

또한, 본 발명은 설치가 용이하여 작업성을 개선할 수 있도록 된 동케이블 철거용 지그를 제공함을 또다른 목적으로 한다.In addition, another object of the present invention is to provide a jig for copper cable removal that can be easily installed to improve workability.

상기한 목적을 달성하기 위하여 본 발명의 지그는 동케이블을 사이에 두고 맞물리는 암부재와 수부재를 포함한다.In order to achieve the above object, the jig of the present invention includes a female member and a male member engaged with the copper cable therebetween.

상기 암부재와 수부재는 볼트로 체결고정될 수 있으며, 두 개의 부재 중 적어도 하나의 부재에는 와이어를 걸기 위한 고리가 설치될 수 있다.The female member and the male member may be fastened and fastened by bolts, and at least one of the two members may be provided with a hook for hanging a wire.

이에 따라 암부재와 수부재를 동케이블에 맞물려 고정시킨 상태에서 고리에 와이어를 걸어 동케이블을 용이하게 인출할 수 있게 되는 것이다.Accordingly, it is possible to easily pull out the copper cable by hooking the wire to the ring in a state where the female member and the male member are fixed to the copper cable.

상기 암부재와 수부재는 내측면에 상기 동케이블이 압착되는 원호형태의 홈이 형성됨이 바람직하다.Preferably, the female member and the male member have an arc-shaped groove in which the copper cable is pressed.

또한, 상기 홈 내주면에 상기 동케이블의 폭방향으로 돌기가 더욱 형성될 수 있다.In addition, a protrusion may be further formed on the inner circumferential surface of the groove in the width direction of the copper cable.

이에 따라 상기 돌기가 동케이블의 표면에 파고들면서 동케이블에 대한 지그 의 파지력을 높일 수 있게 된다.As a result, the projections penetrate the surface of the copper cable, thereby increasing the holding force of the jig for the copper cable.

이하, 첨부한 도면을 참조로 본 발명의 바람직한 실시예에 대해 당업자가 용이하게 실시할 수 있도록 상세히 설명한다. 그러나 본 발명은 여러 가지 상이한 형태로 구현될 수 있으며 여기에서 설명하는 실시예에 한정되는 것은 아니다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

도 1은 본 발명의 실시예에 따른 동케이블 철거용 지그를 도시한 분해 사시도이고, 도 2는 본 발명의 실시예에 따른 지그가 동케이블에 설치된 상태를 도시한 사시도이다.1 is an exploded perspective view showing a jig for copper cable removal according to an embodiment of the present invention, Figure 2 is a perspective view showing a state in which a jig according to an embodiment of the present invention is installed on the copper cable.

상기한 도면에 의하면, 본 실시예에 따른 지그(10)는 서로 맞물려 동케이블(100) 선단에 압착되는 암부재(11)와 수부재(12), 동케이블(100)에 상기 암부재(11)와 수부재(12)를 압착된 상태로 고정시키기 위한 볼트(13), 상기 암부재(11)와 수부재(12)의 일측 선단에 설치되어 동케이블(100)을 끌어당기기 위한 와이어가 체결되는 고리(14)를 포함한다.According to the above drawings, the jig 10 according to the present embodiment is engaged with each other and the female member 11 and male member 12, the female member 12, the copper cable 100 to the crimped end of the copper cable 100, the female member 11 ) And a bolt 13 for fixing the male member 12 in a crimped state, and a wire for attracting the copper cable 100 is installed at one end of the female member 11 and the male member 12. Ring 14 to be included.

상기 암부재(11)는 사각블록 형태의 구조물로 이루어지며 내측면에는 중앙에 길이방향을 따라 동케이블(100)이 밀착되는 원호형태의 홈(15)이 형성된다.The arm member 11 is formed of a rectangular block-like structure and the inner surface is formed with an arc-shaped groove 15 in which the copper cable 100 is in close contact with the longitudinal direction in the center.

상기 수부재(12) 또한 상기 암부재(11)와 동일한 크기의 사각블록 형태의 구조물로 이루어지며 내측면에는 중앙에 길이방향을 따라 동케이블(100)이 밀착되는 원호형태의 홈(15)이 형성된다.The male member 12 is also made of a structure of the rectangular block shape of the same size as the female member 11 and the inner surface is an arc-shaped groove 15 in which the copper cable 100 is in close contact with the longitudinal direction in the center Is formed.

또한, 상기 암부재(11)의 홈(15)과 수부재(12)의 홈(15) 내주면에는 동케이블(100)의 길이방향에 대해 직각 방향으로 다수개의 돌기(16)가 간격을 두고 돌출 형성된다.In addition, the grooves 15 of the female member 11 and the inner peripheral surface of the groove 15 of the male member 12 protrude a plurality of protrusions 16 at intervals perpendicular to the longitudinal direction of the copper cable 100. Is formed.

이에 따라 상기 암부재(11)와 수부재(12)를 동케이블(100)에 설치하였을 때 상기 돌기(16)가 동케이블(100)의 표면에 폭방향으로 파고들어 동케이블(100)을 끌어당기는 방향에 대해 걸림턱 역할을 하게 된다.Accordingly, when the female member 11 and the male member 12 are installed on the copper cable 100, the protrusions 16 penetrate in the width direction on the surface of the copper cable 100 to pull the copper cable 100. It will act as a locking jaw for the pulling direction.

한편, 상기 암부재(11)와 수부재(12)는 동케이블(100) 압착과정에서 동케이블(100)이 암부재(11)와 수부재(12) 사이의 틈새로 삐져 나가는 것을 방지하고 두 부재가 정확히 서로 맞물릴 수 있도록, 상기 수부재(12)는 중앙에 형성되는 홈(15)을 기준으로 상기 암부재(11)와 접하는 상단과 하단의 내측면에 간격을 두고 측벽(17)이 돌출형성된다.Meanwhile, the female member 11 and the male member 12 prevent the copper cable 100 from protruding into the gap between the female member 11 and the male member 12 during the crimping of the copper cable 100. The male member 12 has a side wall 17 spaced apart from the inner surface of the upper and lower ends in contact with the female member 11 with respect to the groove 15 formed at the center so that the members can be accurately engaged with each other. Protruding.

그리고 상기 암부재(11)는 중앙에 형성되는 홈(15)을 기준으로 수부재(12)와 접하는 상단과 하단의 내측면에 상기 측벽(17)과 대응되는 위치에 상기 측벽(17)이 끼워지는 끼움홈(18)이 형성된 구조로 되어 있다.The female member 11 has the sidewall 17 fitted in a position corresponding to the sidewall 17 on the inner and upper surfaces of the upper and lower ends contacting the male member 12 based on the groove 15 formed at the center thereof. The losing fitting groove 18 is formed.

이에 상기 암부재(11)와 수부재(12)를 맞물리게 되면 끼움홈(18)에 측벽(17)이 진입되면서 암부재(11)와 수부재(12) 사이가 막혀져 동케이블(100) 압착과정에서 동케이블(100)이 양 부재 사이로 터져 나가는 것을 방지할 수 있게 된다.Accordingly, when the female member 11 and the male member 12 are engaged with each other, the side wall 17 enters the fitting groove 18 and the female member 11 and the male member 12 are blocked, thereby crimping the copper cable 100. In the process, the copper cable 100 can be prevented from bursting between the two members.

여기서 상기 암부재(11)와 수부재(12)의 체결구조를 살펴보면, 상기 수부재(12)에는 상기 암부재(11)와의 접면을 따라 간격을 두고 홀(19)이 관통형성되고 상기 암부재(11)에는 수부재(12)와의 접면에 상기 홀(19)과 대응되는 위치에 볼트체결홀(20)이 형성된다.Looking at the coupling structure of the female member 11 and the male member 12, the male member 12 is formed through the hole 19 at intervals along the contact surface with the female member 11 through the female member The bolt fastening hole 20 is formed at a position corresponding to the hole 19 at the contact surface with the male member 12.

따라서 볼트(13)가 상기 홀(19)을 관통하여 볼트체결홀(20)에 나사결합되어 암부재(11)와 수부재(12)를 결합시키는 구조로 되어 있다.Therefore, the bolt 13 penetrates the hole 19 and is screwed to the bolt fastening hole 20 so as to couple the female member 11 and the male member 12 to each other.

또한, 상기 암부재(11)와 수부재(12)의 선단에는 각각 와이어를 걸수 있는 원형의 고리(14)가 부착설치 된다.In addition, the front end of the female member 11 and the male member 12 is provided with a circular ring 14 to hang the wire, respectively.

상기한 구조의 지그(10)는 도 3에 도시된 바와 같이 예컨대, 유압식 압축기(200)를 이용하여 동케이블(100)에 가압 밀착된다.As shown in FIG. 3, the jig 10 having the above-described structure is press-contacted to the copper cable 100 using, for example, a hydraulic compressor 200.

상기 유압식 압축기(200)는 동케이블(100)을 사이에 두고 암부재(11)와 수부재(12)에 압력을 가하기 위한 것으로, 암부재(11)와 수부재(12)에 필요한 압력을 가할 수 있는 구조면 특별히 유압식 압축기(200)에 한정되지 않으며 다양한 압력 발생장치가 적용될 수 있다.The hydraulic compressor 200 is for applying pressure to the female member 11 and the male member 12 with the copper cable 100 interposed therebetween, and to apply the necessary pressure to the female member 11 and the male member 12. If the structure can be not particularly limited to the hydraulic compressor 200, various pressure generating devices can be applied.

도 3에 도시된 바와 같이 동케이블(100)을 사이에 두고 암부재(11)와 수부재(12)를 맞물린 상태에서 유압식 압축기(200)에 상기 지그(10)를 장착하고 상기 압축기(200)에 압유를 인가하게 되면 암부재(11)와 수부재(12)가 밀려들어가면서 동케이블(100)을 압착하게 된다.As shown in FIG. 3, the jig 10 is mounted on the hydraulic compressor 200 while the female member 11 and the male member 12 are engaged with the copper cable 100 interposed therebetween, and the compressor 200 is mounted. When the pressure oil is applied to the female member 11 and the male member 12 is pressed into the copper cable 100 is pressed.

이 과정에서 상기 수부재(12)에 형성된 측벽(17)은 암부재(11)에 형성된 끼움홈(18)으로 진행함에 따라 상기 동케이블(100)은 수부재(12)의 홈(15)과 암부재(11)의 홈(15) 그리고 상기 측벽(17)에 의해 둘러쌓인 상태로 압착된다.In this process, the side wall 17 formed on the male member 12 proceeds to the fitting groove 18 formed on the female member 11, so that the copper cable 100 is connected to the groove 15 of the male member 12. It is compressed in a state surrounded by the groove 15 and the side wall 17 of the arm member 11.

상기 암부재(11)와 수부재(12)가 계속 압착되면 수부재(12)의 측벽(17)이 암부재(11)의 끼움홈(18) 내에 삽입되면서 암부재(11)와 수부재(12)의 홈(15)에 의해 만들어지는 공간은 점차로 좁아져 상기 동케이블(100)을 압착하게 된다. When the female member 11 and the male member 12 are continuously pressed, the side wall 17 of the male member 12 is inserted into the fitting groove 18 of the female member 11 and the female member 11 and the male member ( The space made by the groove 15 of 12 is gradually narrowed to compress the copper cable 100.

상기 암부재(11)와 수부재(12)가 완전히 밀착되면 상기 홈(15)의 내주면은 상기 동케이블(100)과 완전히 밀착되고 동케이블(100)은 외피 뿐만 아니라 내부 심 선 등이 공극이 없는 상태로 최대한 하나로 압착된다.When the female member 11 and the male member 12 are completely in contact with each other, the inner circumferential surface of the groove 15 is completely in contact with the copper cable 100, and the copper cable 100 has an air gap as well as an inner core wire. It is squeezed as much as possible without being.

이와같이 암부재(11)와 수부재(12)가 동케이블(100)을 압착한 상태에서 수부재(12)의 홀(19)을 통해 볼트(13)를 삽입하여 암부재(11)의 볼트체결홀(20)에 체결함으로서 암부재(11)와 수부재(12)를 결합시키고 동케이블(100)에 대한 압착 상태를 유지시킨다.In this manner, the female member 11 and the male member 12 press the copper cable 100 to insert the bolt 13 through the hole 19 of the male member 12 to fasten the bolt of the female member 11. By fastening to the hole 20, the female member 11 and the male member 12 are coupled to each other and the crimping state of the copper cable 100 is maintained.

상기와 같이 지그(10)가 동케이블(100)에 장착되면 유압식 압축기(200)를 제거하고 상기 지그(10)의 암부재(11)와 수부재(12)에 설치된 고리(14)에 와이어를 걸어 당김으로서 용이하게 동케이블(100)을 인출할 수 있게 된다.When the jig 10 is mounted to the copper cable 100 as described above, the hydraulic compressor 200 is removed and the wire is connected to the ring 14 installed in the female member 11 and the male member 12 of the jig 10. By pulling out, the copper cable 100 can be easily taken out.

여기서 상기 동케이블(100)은 지그(10)가 단단히 고정하고 있는 상태로 와이어는 고리(14)를 통해 지그(10)를 당기는 상태로 와이어에 의한 당김력은 그대로 지그(10)에 전달되어 지그(10)에 단단히 고정된 동케이블(100)을 끌어낼 수 있는 것이다.The copper cable 100 is a jig 10 in a state where the jig 10 is firmly fixed, the wire is pulled by the jig 10 through the ring 14, the pulling force by the wire is transmitted to the jig 10 as it is jig The copper cable 100 firmly fixed to the (10) can be pulled out.

또한, 상기 암부재(11)와 수부재(12)의 홈(15) 내면에 형성된 돌기(16)는 동케이블(100) 외피에 폭방향으로 박혀짐에 따라 지그(10)를 와이어로 당기는 과정에서 지그가 동케이블(100)에서 미끄러져 분리되는 것을 더욱 방지하게 된다.In addition, the protrusion 16 formed on the inner surface of the groove 15 of the female member 11 and the male member 12 is a process of pulling the jig 10 by a wire as it is embedded in the outer surface of the copper cable 100. In the jig is further prevented from sliding off the copper cable (100).
