The second pinion 71 receives the reverse rotation signal from the controller 60. ) Is composed of a drive motor 70 forcibly rotating in the forward and reverse directions, as shown in FIGS. 1 to 3.

상기 지지대(10,10')는 전체적인 형상이 직사각형태를 이루는 관으로서, 일단부에는 수평하게 관통되는 가이드홈(11)이 형성되고, 가이드홈(11)의 내주면에는 내향으로 돌출되는 돌부(11a)가 일체로 형성되며, 타단부에는 한 쌍의 밴드부재(B)가 마련되어 있어 이를 매개로 전주(P)의 외면에 고정설치된다.The support (10, 10 ') is a tube of the overall shape of a rectangular shape, one end is formed with a guide groove 11 penetrating horizontally, the inner peripheral surface of the guide groove 11 protruding inwardly 11a ) Is formed integrally, and the other end is provided with a pair of band members (B) is fixed to the outer surface of the electric pole (P) through this.

본 실시 예의 경우 상기 가이드홈(11)의 내주면에는 이후에 설명될 길이조절부재(40,40')가 이동가능하게 삽입되되, 가이드홈(11)의 돌부(11a)와 길이조절부재(40,40')의 결합홈(42a)이 상호 결합되는 구조를 이룬다.In the present embodiment, the length adjusting members 40 and 40 ', which will be described later, are inserted into the inner circumferential surface of the guide groove 11, and the protrusion 11a and the length adjusting member 40 of the guide groove 11 are movable. The coupling groove 42a of the 40 'is formed to be coupled to each other.

(40, 40 ') is coupled to the inner peripheral surface of the first pinion (30).

그리고, 상기와 같이 설치한 상태에서 지지대(10,10') 사이에 가이드부재(G)를 매개로 랙(20)을 설치고정하여 지지대(10,10') 사이에 배치된 제1피니언(30) 및 제2피니언(71)과 상호 맞물리도록 함으로서, 그 설치를 완료한다.
In addition, the first pinion 30 disposed between the supports 10 and 10 'is fixed by installing the rack 20 between the supports 10 and 10' by the guide member G in the installed state. ) And the second pinion 71 to be engaged with each other, thereby completing the installation.

상기 길이조절 완철의 작동관계를 설명하면, 온도의 변화가 극히 적은 봄과 가을의 경우에는 가공배전선(L)의 길이변화가 적기 때문에 도 3에 도시된 바와 같이 가공배전선(L)이 안정된 상태로 애자(41)에 고정되어 있게 된다.
Referring to the operation relationship of the length control complete iron, in the case of spring and autumn when the change in temperature is very small, because the change in the length of the processing distribution line (L) is small, as shown in Figure 3 the processing distribution line (L) in a stable state It is fixed to the insulator 41.

하지만, 여름철과 같이 온도가 상승하게 되면 지지대(10,10')에 설치된 온도센서(50)가 외부온도를 실시간으로 측정하여 측정된 값을 제어부(60)로 출력하게 되고, 제어부(60)는 온도센서(50)로부터 실시간으로 측정된 값을 전달받아 현재 외부온도상태를 판단하게 된다.However, when the temperature rises as in the summer, the temperature sensor 50 installed on the support 10, 10 ′ measures the external temperature in real time and outputs the measured value to the controller 60. The real time temperature is determined by receiving the measured value from the temperature sensor 50 in real time.

본 실시 예의 경우 여름철의 온도가 상승되면, 가공배전선(L)이 팽창되어 처짐현상에 의해 애자(41)에 이탈하려고 하기 때문에 가공배전선(L)이 긴장된 상태를 유지할 수 있도록 제어부(60)는 구동모터(70)로 정회전 동작신호를 출력하게 된다.In the case of the present embodiment, when the temperature of the summer rises, the control line 60 is driven so that the overhead line (L) is inflated and tries to leave the insulator 41 due to deflection, so that the overhead line (L) can be maintained in a tensioned state. The forward rotation operation signal is output to the motor 70.

따라서, 상기 제어부(60)로부터 정회전 동작신호를 전달받은 구동모터(70)는 정방향으로 회전하게 되고, 이로 인해 모터축(미도시)에 고정되어 있는 제2피니언(71)은 강제로 회전되어 랙(20)을 길이방향(전방)으로 밀게 되며, 전방을 향하여 이동되는 랙(20)에 의해 랙(20)의 상면에 맞물려 있는 제1피니언(30)은 역방향으로 회전하게 된다.Therefore, the driving motor 70 receiving the forward rotation operation signal from the control unit 60 rotates in the forward direction, and thus the second pinion 71 fixed to the motor shaft (not shown) is forcibly rotated. The rack 20 is pushed in the longitudinal direction (front), and the first pinion 30 engaged with the upper surface of the rack 20 by the rack 20 moving forward is rotated in the reverse direction.

상기 제1피니언(30)이 반시계방향으로 회전하게 되면 제1피니언(30)의 내주면에 체결되어 있는 길이조절부재(40,40')는 제1피니언(30)의 내부 중심을 향해 이동하게 되고, 애자(41)에 고정되어 있는 가공배전선(L) 역시 이동되는 길이조절부재(40,40')에 의해 당겨져 긴장상태를 유지하게 되므로서, 가공배전선(L)의 처짐현상을 방지할 수 있게 되는 것이며, 이를 도 5a와 같이 도시하였다.
When the first pinion 30 rotates in the counterclockwise direction, the length adjusting members 40 and 40 'which are fastened to the inner circumferential surface of the first pinion 30 move toward the inner center of the first pinion 30. In addition, the processing distribution line L fixed to the insulator 41 is also pulled by the length adjusting members 40 and 40 'which are moved to maintain the tension state, thereby preventing the processing distribution line L from sagging. As shown in Figure 5a.

한편, 이와는 반대로 겨울철에는 가공배전선(L)이 수축되면서 길이가 짧아져 팽팽한 상태로 있게 되는데, 이러한 경우 온도센서(50)는 외부온도를 실시간으로 측정하여 측정된 값을 제어부(60)로 출력하게 되고, 제어부(60)는 온도센서(50)로부터 실시간으로 측정된 값을 전달받아 현재 외부온도상태를 판단하게 된다.On the other hand, on the contrary, in winter, as the processing distribution line L contracts, the length becomes shorter and becomes in a taut state. In this case, the temperature sensor 50 measures the external temperature in real time and outputs the measured value to the controller 60. The controller 60 receives the measured value in real time from the temperature sensor 50 to determine the current external temperature state.

본 실시 예의 경우 겨울철과 같이 온도가 낮아지게 되면, 가공배전선(L)이 수축에 의해 애자(41)에서 이탈하려고 하기 때문에 가공배전선(L)이 어느 정도 이완될 수 있도록 제어부(60)는 구동모터(70)로 역회전 동작신호를 출력하게 된다.In the case of the present embodiment, when the temperature is lowered, such as winter, since the process distribution line (L) is to be separated from the insulator 41 by contraction, the control unit 60 is a drive motor so that the process distribution line (L) can be relaxed to some extent. At 70, the reverse rotation operation signal is output.

따라서, 상기 제어부(60)로부터 역회전 동작신호를 전달받은 구동모터(70)는 역방향으로 회전하게 되고, 이로 인해 모터축(미도시)에 고정되어 있는 제2피니언(71)은 강제로 회전되어 랙(20)을 후방(지주방향)으로 밀게 되며, 후방을 향하여 이동되는 랙(20)에 의해 랙(20)의 상면에 맞물려 있는 제1피니언(30)은 시계방향으로 회전하게 된다.Accordingly, the driving motor 70 receiving the reverse rotation operation signal from the control unit 60 rotates in the reverse direction, thereby forcibly rotating the second pinion 71 fixed to the motor shaft (not shown). The rack 20 is pushed backward (the circumferential direction), and the first pinion 30 meshed with the upper surface of the rack 20 by the rack 20 moving toward the rear is rotated clockwise.

상기 제1피니언(30)이 시계방향으로 회전하게 되면 제1피니언(30)의 내주면에 체결되어 있는 길이조절부재(40,40')는 제1피니언(30)의 내부에서 외측을 향해 이동하게 되고, 애자(41)에 고정되어 있는 가공배전선(L) 역시 이동되는 길이조절부재(40,40')와 함께 이동되어 이완된 상태를 유지하게 되므로서, 가공배전선(L)이 과도한 수축에 의해 애자(41)에서 이탈되는 것을 방지할 수 있게 되는 것이며, 이러한 일련의 과정을 도 5b와 같이 도시하였다.When the first pinion 30 is rotated in the clockwise direction, the length adjusting members 40 and 40 'which are fastened to the inner circumferential surface of the first pinion 30 are moved outward from the inside of the first pinion 30. And the overhead line L fixed to the insulator 41 is also moved together with the length adjusting members 40 and 40 'to be moved to maintain a relaxed state, so that the overhead line L is excessively contracted. It is possible to prevent the departure from the insulator 41, this series of processes are shown as shown in Figure 5b.

상기와 같이 지지대(10,10')에 제1피니언(30)과 말단에 가공배전선(L)이 고정된 길이조절부재(40,40')를 설치하고, 제1피니언(30)에 의해 길이가 조절될 수 있도록 이를 제어하는 온도센서(50)와 제어부(60) 및 구동모터(70)를 설치하여 줌으로서, 가공배전선(L)이 온도변화에 의해 처지거나 또는 수축되어 애자(41)로부터 이탈되거나 끊어지는 것을 미연에 방지할 수 있으며, 또한, 비교적 단순한 구성으로 되어 있어 조립이 쉽고 간편하며 수리 및 교체가 상당히 용이한 장점이 있다.As described above, the length adjustment members 40 and 40 'having the first pinion 30 and the processing distribution line L fixed to the ends 10 and 10' are fixed to the support pins 10 and 10 ', and the lengths are defined by the first pinion 30. By installing the temperature sensor 50, the control unit 60 and the drive motor 70 to control this so that the control can be adjusted, the overhead distribution line (L) is sag or contracted by the change in temperature from the insulator 41 It is possible to prevent the departure or breaking in advance, and also has a relatively simple configuration has the advantage of easy and simple assembly and easy repair and replacement.
