Description

가공송전선의 안정적 설치를 위한 지지기구{Support mechanism for stable installation of overhead transmission lines}Support mechanism for stable installation of overhead transmission lines

본 발명은 가공송전선의 안정적 설치를 위한 지지기구에 관한 것이다.The present invention relates to a support mechanism for stable installation of overhead power transmission lines.

가공송전선은 전력공급을 위하여 발전소에서 생산되는 전력을 변전소를 통하여 각 지역으로 공급하기 위한 전력시설로서, 가공송전선은 철탑(송전탑)의 암에 의해 지지된다.The overhead power transmission line is a power facility for supplying electric power produced by a power plant to each region through a substation for power supply. The overhead power transmission line is supported by the arm of a steel tower (transmission tower).

이러한 철탑(송전탑)들은 가공송전선들을 안정되게 지지할 수 있도록 발전소와 변전소의 사이에 일정 간격으로 설치된다.These steel towers (transmission towers) are installed at regular intervals between the power plant and the substation to stably support overhead transmission lines.

한편, 철탑(송전탑)들로 이어지는 가공송전선 사이는 점퍼선을 매개로 전기적으로 연결되며, 점퍼선은 애자에 고정된다.On the other hand, between the overhead power transmission lines leading to the pylon (transmission tower) is electrically connected via a jumper wire, the jumper wire is fixed to the insulator.

그런데 상기와 같은 점퍼선 고정을 위한 애자는 작업자가 지상에서부터 철탑까지 들고 올라가거나, 철탑 위에 작업자가 밧줄을 내려주면 지상에 작업자가 밧줄에 애자를 묶고, 철탑 위에 작업자는 밧줄을 잡아당겨 애자를 철탈까지 끌어올려야 하기 때문에 작업이 힘들고 이로 인해 작업성이 떨어질 수밖에 없었으며, 작업자의 근골격 부상 및 애자가 추락하는 등의 안전사고가 항상 문제로 지적되어 왔다.However, the insulator for fixing the jumper wire as described above, when the worker lifts from the ground to the pylon, or when the worker lowers the rope on the pylon, the worker binds the insulator to the rope on the ground, and the worker on the pylon pulls the rope to escape the insulator. Since it has to be lifted up to this point, the work is difficult, and the workability is inevitably reduced, and safety accidents such as musculoskeletal injuries and insulators of workers have always been pointed out as a problem.

상기 도르래(50)는 철탑암(1)에 설치되어 로프(41)의 이동시 마찰을 줄여주는 역할을 한다.The pulley 50 is installed on the pylon arm 1 and serves to reduce friction when moving the rope 41.

상기 작동스위치(60)는 철탑암(1)에 설치되어 윈치(40)를 동작제어하는 역할을 한다.The operation switch 60 is installed on the tower arm 1 serves to control the operation of the winch 40.

일 예로, 상기 작동스위치(60)의 외부로 노출된 버튼(도 1 참조)을 누르게 되면 윈치(40)가 동작되어 로프(41)를 감거나 풀게 되며, 이로 인해 로프(41)와 연결된 가이드블록(20)은 승강(昇降)하게 된다.For example, when the button (see FIG. 1) exposed to the outside of the operation switch 60 is pressed, the winch 40 is operated to wind or loosen the rope 41, thereby causing the guide block to be connected to the rope 41. (20) will go up and down.

한편, 상기 윈치(40)와 작동스위치(60)는 배터리 또는 외부로부터 전원을 공급받는다.Meanwhile, the winch 40 and the operation switch 60 are supplied with power from a battery or an external device.

상기와 같은 구성으로 이루어진 본 발명의 지지기구의 작용효과를 설명하면 다음과 같다.When explaining the effect of the support mechanism of the present invention made of the above configuration is as follows.

먼저, 철탑으로 올라간 작업자는 작동스위치(60)를 매개로 윈치(40)를 조작하여 로프(41)를 풀어주게 되면, 로프(41)와 연결된 가이드블록(20)이 지상까지 하강하게 된다.First, when the operator climbs the pylon to release the rope 41 by operating the winch 40 through the operation switch 60, the guide block 20 connected to the rope 41 descends to the ground.

상기 가이드블록(20)이 하강하면 지상에 작업자는 가이드블록(20)과 점퍼선고정애자(30)를 제1링크부(24)와 제2링크부(32) 및 연결부재(C)를 매개로 상호 연결해 준다.When the guide block 20 descends, an operator on the ground uses the guide block 20 and the jumper wire anchor 30 through the first link portion 24, the second link portion 32, and the connecting member C. Interconnects.

상기와 같은 연결작업이 완료되면, 도 6a에 도시된 바와 같이, 철탑에 있는 작업자는 작동스위치(60)를 매개로 윈치(40)를 조작하여 로프(41)가 감기도록 하며, 감겨 승강하는 로프(41)에 의해 가이드블록(20)과 점퍼선고정애자(30)는 따라서 승강하게 된다.When the connection operation as described above is completed, as shown in FIG. 6A, the operator in the pylon operates the winch 40 through the operation switch 60 so that the rope 41 is wound, and the rope is wound up and down. By (41), the guide block 20 and the jumper wire insulator 30 are thus elevated.

상기와 같이 로프(41)에 의해 승강된 가이드블록(20)은, 도 6b에 도시된 바와 같이, 루프(10)의 내측으로 인입되어 제2수직부(21)가 관부(12)에 서서히 끼워지게 된다.The guide block 20 lifted by the rope 41 as described above, as shown in Figure 6b, is drawn into the inside of the roof 10, the second vertical portion 21 is gradually fitted into the tube portion 12 Lose.

한편, 상기와 같이 가이드블록(20)이 루프(10)의 내측으로 인입되는 과정에 가이드블록(20)의 좌우에 마련된 삼각형태(도 5 참조) 부분이 루프(10)의 호형 내주면에 맞닿게 되면, 도 6c에 도시된 바와 같이, 가이드블록(20)의 좌우에 마련된 삼각형태(도 5 참조) 부분은 루프(10)의 호형 내주면을 따라 시계 또는 반시계방향으로 안내되면서 루프(10)의 삼각형태 부분으로 자연스럽게 유도되고, 이에 따라 가이드블록(20)은 루프(10)의 내면을 따라 안정적으로 루프(10)의 내부 끝까지 인입되며, 이와 같이 가이드블록(20)이 완전하게 인입되면 제1볼트결합공(12a)과 제2볼트결합공(21a)은 자연스럽게 상호 연통된 구조를 이루게 된다.On the other hand, as described above, in the process in which the guide block 20 is drawn into the inside of the roof 10, the triangular shape (see FIG. 5) provided on the left and right sides of the guide block 20 is in contact with the arc inner circumferential surface of the roof 10. As shown in FIG. 6C, the triangular shape (see FIG. 5) provided on the left and right sides of the guide block 20 is guided clockwise or counterclockwise along the arc inner circumferential surface of the loop 10 while It is naturally guided to the triangular part, and accordingly, the guide block 20 is stably drawn along the inner surface of the loop 10 to the inner end of the loop 10, and thus, when the guide block 20 is completely drawn, the first The bolt coupling hole 12a and the second bolt coupling hole 21a naturally form a structure in communication with each other.

따라서, 작업자는 제1볼트결합공(12a)과 제2볼트결합공(21a)을 맞추기 위한 수고로움을 크게 덜 수 있기 때문에 작업의 편의성이 극대화되는 것이다.Therefore, the operator can maximize the convenience of the work because it greatly reduces the trouble of aligning the first bolt coupling hole 12a and the second bolt coupling hole 21a.

상기와 같이 제1·2볼트결합공(12a,21a)이 상호 연통되면, 도 6d에 도시된 바와 같이, 고정부재(F)인 볼트를 관통되게 끼워 넣어 관부(12)와 제2수직부(21)가 서로 일체형을 이루도록 만들어 주고, 관통된 볼트의 단부에는 고정부재(F)인 너트를 체결하여 볼트의 이탈을 방지토록한다.As described above, when the first and second bolt coupling holes 12a and 21a communicate with each other, as shown in FIG. 6D, the bolt 12 which is the fixing member F is inserted through the tube portion 12 and the second vertical portion ( 21) are made to form an integral type with each other, and a nut, which is a fixing member (F), is fastened to the end of the bolt to prevent the bolt from coming off.

상기와 같이 루프(10)와 가이드블록(20)의 결합이 완료되면, 점퍼선고정애자(30)의 점퍼선억류구(34)를 분리한 다음 점퍼선배치부(33)의 점퍼선(J)을 배치하고, 점퍼선배치부(33)에 점퍼선(J)이 배치되면 점퍼선억류구(34)를 결합돌기(34a)을 매개로 결합홈(33b)에 끼워 상호 결합함으로써 점퍼선(J)을 고정한다.When the combination of the loop 10 and the guide block 20 is completed as described above, the jumper wire retainer 34 of the jumper wire fixing insulator 30 is separated, and then the jumper wire J of the jumper wire arrangement unit 33 is removed. When the jumper line (J) is placed in the jumper line arrangement part 33, the jumper line (J) is inserted into the coupling groove (33b) through the coupling protrusion (34a) through the coupling protrusion (34a). To fix.

한편, 상기와 같이 설치된 상태에서 바람에 의한 외력이 점퍼선(J)에 가해지게 될 경우 점퍼선고정애자(30)의 제2링크부(32)가 연결부재(C)를 중심으로 스윙되면서 횡진에 의해 충격을 완화시켜주게 준다.On the other hand, when the external force due to the wind is applied to the jumper wire (J) in the installed state as described above, the second link portion (32) of the jumper wire retainer (30) swings around the connecting member (C), and thus Gives the shock to be relieved.
