Abstract

The present invention relates to a fixing instrument for enhancing convenience of an overhead distribution line, which comprises: cross arms (100) having an electric pole (P) interposed therebetween to be fixed at a top end portion of the electric pole (P) and be parallel to each other; an electric line fixing unit (200) interposed between overhead distribution lines (L) to electrically insulate the overhead distribution line (L) from the cross arm (100) and electrically connect and fix the overhead distribution line (L) to a jumper line (J); and a branching unit (300) enabling a branching process in order to draw out a branched line (L') from the overhead distribution line (L). Accordingly, a connection clamp and a housing are formed to be able to rotate, thereby allowing the housing and a branched sleeve to be joined to or separated from each other by simple rotation. In particular, when the housing is separated from the branched sleeve, the housing is connected to the connection clamp, so that there is no need for storing the same separately. Therefore, a risk of falling or loss can be fundamentally reduced in a process of separating the housing.

애자와 전선을 접속하는 인류 클램프에는 인류 클램프 커버가 씌워져 접속 개소의 충전 부위가 절연되어 사용될 수 있다. The human clamp cover connecting the insulator and the electric wire is covered with the human clamp cover, so the charging part of the connection point can be insulated and used.

이러한 경우는 활선 작업과 같은 인위적인 접근이 없는 전제하에 이루어질 수 있다. This case can be done under the premise that there is no artificial approach such as live wire work.

따라서, 활선 작업시에는 작업자나 작업용 장비의 접근이 수시로 이루어지기 때문에 안전을 위해 충분한 절연 특성과 기계적으로 우수한 강도를 가진 활선 작업용 절연커버가 필수적으로 갖추어져야만 한다.Therefore, when working with a live wire, since a worker or equipment for work is frequently accessed, an insulating cover for a live wire operation having sufficient insulation properties and mechanically excellent strength for safety must be essential.

이러한 절연커버와 관련된 종래 기술로는 대한민국 등록특허 제10-2091609호(가공배전선로 활선작업용 신축형 전선 커버)가 있으며, 여기에는 가공배전선로의 활선작업시 작업범위에 따라 길이조절이 가능하여 작업 범위를 모두 커버한 상태에서 안전하게 활선작업을 진행할 수 있는 기술이 개시되어 있다.As a prior art related to such an insulation cover, there is Republic of Korea Patent Registration No. 10-2091609 (extensible wire cover for live wire work of overhead distribution lines), which allows length adjustment according to the work range during live wire work of overhead distribution lines. A technology that can safely perform live wire work in a state in which the entire range is covered is disclosed.

In this embodiment, a branch operation is performed so that the branch line L' can be drawn out from the overhead distribution line L. is used for the purpose of

상기 분기슬리브(310)는 클램핑부(311)와 분기선안착부(312) 및 고정핀(313)으로 구성되는 전도성재질로 제작된 부재로서, 본 실시 예의 경우 가공배전선(L)의 외주면에 감착되어 가공배전선(L)과 분기선(L')을 전기적으로 상호 연결해주는 역할을 한다. 여기서 클램핑부(311)는 가공배전선(L)의 외주면에 감착된 상태에서 공구의 가압력에 의해 오므려지면서 가공배전선(L)의 외주면에 견고하게 고정된다. 이러한 클램핑부(311)의 중간 외주면에는 도르래의 단면과 같이 오목하게 함몰된 형상을 갖는 분기선안착부(312)가 일체로 형성되며, 이 분기선안착부(312)에는 분기선(L')이 감긴 상태로 수용된다. The branch sleeve 310 is a member made of a conductive material consisting of a clamping part 311, a branch line seating part 312, and a fixing pin 313. In this embodiment, it is attached to the outer peripheral surface of the overhead distribution line (L). It serves to electrically interconnect the overhead distribution line (L) and the branch line (L'). Here, the clamping part 311 is firmly fixed to the outer circumferential surface of the overhead power distribution line (L) while being tightened by the pressing force of the tool in a state where it is attached to the outer circumferential surface of the overhead power distribution line (L). A branch line seating part 312 having a concave recessed shape like the cross-section of a pulley is integrally formed on the intermediate outer peripheral surface of the clamping part 311, and the branch line L' is wound around the branch line seating part 312. is accepted as

한편, 상기 분기선안착부(312)에 분기선(L')을 감아 고정하게 되면, 분기선안착부(312)의 내면을 따라 분기선(L')이 슬립되고, 이러한 과정이 반복될 경우 클램핑부(311)가 가공배전선(L)의 외주면을 중심으로 회전하게 되는 문제가 있다.On the other hand, when the branch line L' is wound around the branch line seating part 312 and fixed, the branch line L' slips along the inner surface of the branch line seating part 312, and when this process is repeated, the clamping part 311 ) has a problem in that it rotates around the outer peripheral surface of the overhead distribution line (L).

이에 본 실시 예에서는 클램핑부(311)의 내주면과 분기선안착부(312)의 내면에 원뿔형상의 고정핀(313)을 일체로 형성시켜 주었다. 여기서 클램핑부(311)의 내주면에 형성된 고정핀(313)은 클램핑부(311)의 가압시 가공배전선(L)의 내측으로 파고 들어가 가공배전선(L)과 일체형 구조를 이루게 되고, 분기선안착부(312)에 형성된 고정핀(313)은 분기선(L')이 수용되는 과정에 자중에 의해 고정핀(313)이 분기선(L')의 내측으로 파고 들어가 일체형 구조를 이루게 된다. 이에 따라 고정핀(313)을 매개로 가공배전선(L) 및 분기선(L')을 분기슬리브(310)에 견고하게 고정시켜 줄 수 있게 된다.Accordingly, in this embodiment, the conical fixing pin 313 is integrally formed on the inner peripheral surface of the clamping part 311 and the inner surface of the branch line seating part 312 . Here, the fixing pin 313 formed on the inner circumferential surface of the clamping part 311 digs into the overhead distribution line L when the clamping part 311 is pressed to form an integrated structure with the overhead distribution line L, and the branch line seating part ( In the fixing pin 313 formed on the 312, the fixing pin 313 digs into the inside of the branch line L' by its own weight while the branch line L' is accommodated to form an integrated structure. Accordingly, it is possible to firmly fix the overhead distribution line (L) and the branch line (L') to the branch sleeve 310 via the fixing pin 313 .

상기 분기선고정링(320)은, 도 3a 및 도 3b에 도시된 바와 같이, 고리형상으로 포개진 분기선(L')에 끼워져 포개진 부분을 가압해 고정하는 역할을 한다.The branch line fixing ring 320, as shown in FIGS. 3A and 3B, is inserted into the branch line (L') overlapped in an annular shape and serves to press and fix the overlapped portion.

상기 하우징(330)은 제1·2바디(331A,331B)와 슬리브수용부(332), 분기선감착부(333) 및 링크암(334)으로 구성된 절연재질의 부재로서, 본 실시 예의 경우 전선고정유닛(200)의 연결암(240)에 회동가능하게 설치되어 분기슬리브(310)를 감싸 외부로 노출되지 않게 하는 역할을 한다.The housing 330 is a member of an insulating material composed of the first and second bodies 331A and 331B, the sleeve receiving part 332 , the branch wire fitting part 333 and the link arm 334 , and in this embodiment, the wire is fixed. It is rotatably installed on the connecting arm 240 of the unit 200 to surround the branch sleeve 310 so as not to be exposed to the outside.

상기 제1·2바디(331A,331B)는 전체적으로‘T’자 형상을 이루며, 분할형성되어 상호 결합된다. 이러한 제1·2바디(331A,331B)는 양측면과 하단만 절개되어 있어 강제로 벌리거나 오므리게 할 수 있다. 또한, 제1·2바디(331A,331B)의 내부에는 전후방향으로 슬리브수용부(332)가 형성되고, 상하방향으로 분기선감착부(333)가 일체로 형성된다. 여기서 슬리브수용부(332)에는 분기슬리브(310)가 삽탈가능하게 수용되고, 분기선감착부(333)에는 슬리브수용부(332)에 감착된 분기선(L')이 삽탈가능하게 수용된다. 그리고 제1·2바디(331A,331B)에는 링크암(334)이 일체로 형성되는데, 링크암(334)은 제1·2바디(331A,331B)로부터 연결암(240)을 향해 나란하게 연장되어 축핀(P)을 매개로 회동가능하게 연결된다.The first and second bodies 331A and 331B form a 'T' shape as a whole, are divided and are coupled to each other. These first and second bodies (331A, 331B) can be forcibly opened or closed since only both sides and the lower end are incised. In addition, the sleeve receiving portion 332 is formed in the front and rear directions inside the first and second bodies 331A and 331B, and the branch line fitting portion 333 is integrally formed in the vertical direction. Here, the branch sleeve 310 is removably accommodated in the sleeve accommodating part 332 , and the branch line L' fitted to the sleeve accommodating part 332 is removably accommodated in the branch line fitting part 333 . And a link arm 334 is integrally formed with the first and second bodies 331A and 331B, and the link arm 334 extends from the first and second bodies 331A and 331B toward the connecting arm 240 in parallel. It is connected rotatably through the shaft pin (P).

일 예로, 상기 축핀(P)을 중심으로 하우징(330)을 반시계방향으로 회동시켜 주게 되면, 하우징(330)을 분기슬리브(310)로부터 분리시켜줄 수 있게 되고, 하우징(330)을 시계방향으로 회동시켜 주게 되면, 하우징(330)에 의해 분기슬리브(310)가 감싸져 보호된다.For example, if the housing 330 is rotated counterclockwise around the shaft pin P, the housing 330 can be separated from the branch sleeve 310, and the housing 330 can be rotated clockwise. When it is rotated, the branch sleeve 310 is wrapped and protected by the housing 330 .

특히, 상기 분기슬리브(310)로부터 하우징(330)을 분리시 하우징(330)은 연결클램프(230)와 연결되어 있기 때문에 별도로 보관할 필요가 없고, 하우징(330)을 분리하는 과정에 추락의 위험이나 분실의 위험을 근본적으로 낮출 수 있는 이점이 있다.In particular, when the housing 330 is separated from the branch sleeve 310 , the housing 330 is connected to the connection clamp 230 , so there is no need to store it separately, and there is no risk of falling during the process of separating the housing 330 . There is an advantage that can fundamentally lower the risk of loss.

도 4a 내지 도 4c는 본 발명에 따른 가공배전선 편의성 향상 고정기구에서 분기유닛의 사용상태를 설명하기 위한 도면으로서, 이를 참조하여 설명하면 다음과 같다.4A to 4C are views for explaining the use state of the branch unit in the overhead distribution line convenience improvement fixing mechanism according to the present invention, which will be described with reference to the following.

먼저, 가공배전선(L)의 외주면으로 분기슬리브(310)를 끼워 넣은 다음 분기슬리브(310)의 양단부에 마련된 클램핑부(311)를 각각 도구를 이용해 가압한다.First, the branch sleeve 310 is inserted into the outer circumferential surface of the overhead distribution line L, and then the clamping parts 311 provided at both ends of the branch sleeve 310 are pressed using a tool, respectively.

상기와 같이 클램핑부(311)는 가압되어 오므려지면서 가공배전선(L)에 고정되며, 이때 클램핑부(311)의 내면에 마련된 고정핀(313)은 가공배전선(L)의 내부로 파고 들어감에 따라 가공배전선(L)과 클램핑부(311)는 보다 견고하게 고정된다.As described above, the clamping part 311 is fixed to the overhead distribution line (L) while being pressed and closed. Accordingly, the overhead distribution line L and the clamping part 311 are more firmly fixed.

상기와 같이 가공배전선(L)에 분기슬리브(310)가 장착되면, 분기선(L')을 분기슬리브(310)에 감아 고정하는데, 이를 좀 더 구체적으로 설명하면 다음과 같다.When the branch sleeve 310 is mounted on the overhead distribution line L as described above, the branch line L' is wound around the branch sleeve 310 and fixed, which will be described in more detail as follows.

먼저, 분기슬리브(310)의 분기선안착부(312)에 분기선(L')을 감아 준 상태에서 분기선고정링(320)을 이용해 감겨진 끝단부분을 가압해 풀어지지 않게 고정한다.First, in a state in which the branch line L' is wound around the branch line seating portion 312 of the branch sleeve 310, the wound end portion is pressed using the branch wire fixing ring 320 to fix it so as not to be loosened.

이때, 상기 분기선(L')은 자중에 의해 분기선안착부(312)의 내면에 강하게 밀착되는데, 이 과정에 분기선안착부(312)에 마련된 고정핀(313)이 분기선(L')에 꽂히게 되고, 이에 따라 분기슬리브(310)와 분기선(L')은 일체형 구조를 이루게 된다.At this time, the branch line L' is strongly adhered to the inner surface of the branch line seating part 312 by its own weight. Accordingly, the branch sleeve 310 and the branch line L' form an integrated structure.

상기와 같이 분기슬리브(310)에 분기선(L')이 연결된 상태에서 링크암(334)을 매개로 연결암(240)에 연결된 하우징(330)을 축핀(P)을 중심으로 시계방향을 회동시켜 주게 되면, 하우징(330)이 좌우로 벌어지면서 내측으로 분기슬리브(310)와 분기선(L')이 삽입되어 하우징(330)에 의해 감싸져 보호된다.As described above, in a state in which the branch line L' is connected to the branch sleeve 310, the housing 330 connected to the connection arm 240 via the link arm 334 is rotated clockwise around the shaft pin (P). When given, the housing 330 is opened to the left and right, and the branch sleeve 310 and the branch line L' are inserted into the housing 330 to be protected by being surrounded by the housing 330 .

상기와 같은 일련의 과정에 의해 분기작업은 완료된다.The branching operation is completed by a series of processes as described above.

본 실시 예에 의하면, 상기 연결클램프(230)와 하우징(330)을 회동가능한 구조로 형성해 줌으로서 간단한 회동만으로 하우징(330)과 분기슬리브(310)를 서로 결합 및 분리할 수 있고, 특히 분기슬리브(310)로부터 하우징(330)을 분리시 하우징(330)은 연결클램프(230)와 연결되어 있기 때문에 별도로 보관할 필요가 없으므로 하우징(330)을 분리하는 과정에 추락의 위험이나 분실의 위험을 근본적으로 낮출 수 있는 이점이 있다.According to this embodiment, by forming the connecting clamp 230 and the housing 330 in a rotatable structure, the housing 330 and the branch sleeve 310 can be coupled and separated from each other only by simple rotation, and in particular, the branch sleeve When the housing 330 is separated from the 310, the housing 330 is connected to the connection clamp 230, so there is no need to store it separately, so the risk of falling or loss is basically reduced in the process of separating the housing 330. There are advantages to lowering it.
