Description

특고압 배전선 고정용 완철{Cross bar fixing the electric wire}Cross bar fixing the electric wire

본 발명은 특고압 배전선 고정용 완철에 관한 것이다.The present invention relates to a wrought iron for fixing a high-voltage distribution line.

일반적으로 배전선은 지상으로부터 이격된 전주대에 고정되어서, 소비지로 송전되는 전기를 이송한다. 따라서, 배전선은 전도효율이 우수하고 경제적인 금속재질, 특히 구리 등이 적용된다.In general, power distribution lines are fixed to poles spaced from the ground to transfer electricity to the consumer. Therefore, the distribution line is excellent in conduction efficiency and economical metal materials, especially copper is applied.

그런데, 배전선에 적용되는 금속재질은 온도에 따른 팽창 및 수축 변화가 커서, 여름에는 열에 의한 팽창으로 늘어지고, 겨울에는 냉기에 의한 수축으로 팽팽해진다. 따라서, 온도가 높아져서 배전선이 팽창하면, 배전선이 지면 가까이 늘어져서 통행차량 또는 통행인에게 위협을 가할 수 있고, 외관 또한 미려하지 못하다는 문제가 있었다. However, the metal material applied to the distribution line has a large expansion and contraction change according to temperature, so that it expands due to heat expansion in summer and contracts due to cold air in winter. Therefore, when the distribution line expands due to an increase in temperature, the distribution line lags close to the ground, which may pose a threat to a passing vehicle or a pedestrian, and may not be beautiful in appearance.

또한, 온도가 낮아져서 배전선이 수축하면, 배전선이 받는 장력이 커져서 배전선을 고정하는 애자 등에 무리를 줄 수 있다. 물론, 상기 무리는 애자의 수명을 단축시키는 한편, 배전선의 팽창과 수축의 반복으로 자체 길이가 점차 늘어나면서 배전선의 수명 또한 단축시키는 문제가 있었다.In addition, when the distribution line contracts due to a decrease in temperature, the tension applied to the distribution line increases, which may give a strain to the insulator for fixing the distribution line. Of course, the flock shortens the life of the insulator, while the length of the distribution line is gradually increased due to the expansion and contraction of the distribution line, which also shortens the life of the distribution line.

이에 본 발명은 상기와 같은 문제를 해소하기 위해 안출된 것으로, 팽창 및 수축으로부터 배전선이 받는 물리적인 영향을 최소화하고, 고온에 의한 늘어짐을 방지해서 인근을 통행하는 보행자 및 차량을 보호할 수 있는 특고압 배전선 고정용 완철의 제공을 기술적 과제로 한다.Accordingly, the present invention has been made to solve the above problems, it is possible to minimize the physical impact of the distribution line from expansion and contraction, and to prevent slack due to high temperature to protect the pedestrians and vehicles passing through the neighborhood It is a technical problem to provide a finished iron for fixing high-voltage distribution lines.

And the first and second pulleys 230 and 240 which are installed side by side so as to be spaced apart from each other on the upper surface of the rotary car 220 to be forcibly rotated.

탄발형 회전축대(210)는 회전차(220)가 외력을 받아 일방향으로 수평회전할 경우 이에 탄발해 회전차(220)가 원위치로 복귀하도록 지지하는 것으로, 태엽스프링, 토션스프링 또는 코일스프링과 같은 탄성체가 내장되어서, 회전차(220)의 회전을 위한 회전력을 발생시킬 것이다. 참고로, 본 발명에 따른 탄발형 회전축대(210)의 탄발력은 배전선(11)을 당겨서 배전선(11)이 늘어짐 없이 팽팽한 상태를 유지할 수 있는 방향으로 발생한다.When the rotary car 220 is rotated horizontally in one direction under the external force by the rotary car 220 is supported by the rotary car 220 to return to the original position, such as a spring, torsion spring or coil spring The elastic body is built in, thereby generating a rotational force for the rotation of the rotary car 220. For reference, the elastic force of the ball-type rotary shaft 210 according to the present invention is generated in a direction that can maintain a taut state without pulling the distribution line 11 by pulling the distribution line (11).

At this time, the peripheral surface of the main roll 231 and the sub-roll 231 has a gear is formed, the inner surface of the engaging surface 310 formed on the side of the support (300, 300 ') and the inner surface of the electric pole center 120 Each of the first and second pulleys 230 and 240 is interlocked with the first and second support members 300 and 300 ′ and the electric pole central part 120.

이에 대한 보다 상세한 설명은 제1,2지지대(300, 300')의 내용 설명과 더불어 한다.A more detailed description thereof will be given with the description of the contents of the first and second supports 300 and 300 '.

제1,2지지대(300, 300')는 배전선(11)이 애자(10)를 매개로 일단의 일측에만 일방향으로 연결되고, 타단이 전주 중부(120)의 개구홈(121)으로 삽입돼 일면에 형성된 걸림면(310)이 제1,2활차(230, 240)의 서브롤(232)과 각각 맞물린다. The first and second support members 300 and 300 'have one side in which the distribution line 11 is connected to only one side of one end via the insulator 10, and the other end is inserted into the opening groove 121 of the central pole 120. Engaging surfaces 310 formed in the first and second pulleys 230 and 240 are engaged with the sub-rolls 232, respectively.

이때, 상기 걸림면(310)은 도시한 바와 같이 제1,2지지대(300, 300')의 길이방향을 따라 오목하게 형성되고, 이에 상응해서 제1,2활차(230, 240)는 걸림면(310)의 가장자리를 따라 돌출된 부분이 맞물리는 경계홈(233)이 형성된다. 여기서, 경계홈(233)은 메인롤(231)과 서브롤(232)을 경계선이 될 수도 있을 것이다.At this time, the locking surface 310 is formed in the concave along the longitudinal direction of the first and second support (300, 300 '), as shown, the first and second pulleys (230, 240) correspondingly Boundary grooves 233 are formed to engage portions protruding along the edges of the 310. Here, the boundary groove 233 may be a boundary line between the main roll 231 and the sub roll 232.

이를 통해 제1,2지지대(300, 300')와 제1,2활차(230, 240)는 상호 긴밀하게 맞물려서, 이탈 없이 정밀하게 연동한다.Through this, the first and second support members 300 and 300 'and the first and second pulleys 230 and 240 are closely interlocked with each other to precisely interlock without departure.

계속해서, 제1,2지지대(300, 300')는 서로 이격 배치된 제1,2활차(230, 240) 사이에 이동가능하게 배치되되, 제1,2지지대(300, 300')가 마주하는 측면은 서로 밀착시켜서 제1,2지지대(300, 300')가 각자를 서로를 고정하는 기능을 갖도록 한다. 물론, 이러한 밀착은 제1,2지지대(300, 300')의 수평이동시 마찰을 일으키므로, 상기 측면에 리스를 도포하거나 바퀴를 고정시켜서 상기 마찰을 줄여야 할 것이다.Subsequently, the first and second supports 300 and 300 'are movably disposed between the first and second pulleys 230 and 240 spaced apart from each other, and the first and second supports 300 and 300' face each other. The sides are in close contact with each other so that the first and second support members 300 and 300 'have a function of fixing each other. Of course, such close contact causes friction during horizontal movement of the first and second supports 300 and 300 ', so that the friction should be reduced by applying a lease to the side or fixing the wheel.

한편, 제1,2지지대(300, 300')가 마주하는 측면에는 각각 스토퍼(320)와 가이드(330)가 형성될 수 있다. 즉, 제1지지대(300)의 측면에 스토퍼(320)가 돌출형성되면, 제2지지대(300')의 측면에 스토퍼(320)가 맞물리는 홈 형상의 가이드(330)가 형성되어서, 제1,2지지대(300, 300')의 수평이동이 상호 이탈 없이 정밀하게 안내된다.Meanwhile, stoppers 320 and guides 330 may be formed on side surfaces of the first and second support members 300 and 300 ′ that face each other. That is, when the stopper 320 protrudes from the side surface of the first support 300, a groove-shaped guide 330 into which the stopper 320 is engaged with the side surface of the second support 300 ′ is formed, and thus the first support 300 is formed. The horizontal movements of the two supports 300, 300 'are precisely guided without mutual deviation.

본 발명에 따른 완철은 제1,2지지대(300, 300')의 일단의 일측에만 다수의 배전선(11)을 연결할 수 있도록 세로방향으로 배치되는 고정체(350)를 더 포함하고, 이 고정체(350)는 제1,2지지대(300, 300')를 따라 이동가능하도록 고정된다.Wrought iron according to the present invention further includes a fixture 350 disposed in the longitudinal direction so as to connect a plurality of distribution lines 11 to only one side of one end of the first and second support 300, 300 ′, the fixture 350 is fixed to be movable along the first and second supports 300 and 300 '.

이를 좀 더 상세히 설명하면, 제1,2지지대(300, 300') 일단의 일측에는 돌출된 한 쌍의 고정편(340)이 마주하게 형성되는데, 이 고정편(340)은 나사산이 형성된 스크류(360)를 제1,2지지대(300, 300')의 길이방향과 나란하면서 회전가능하도록 고정시킨다. 한편, 상기 고정체(350)는 스크류(360)가 관통해 맞물리는 너트홀(351)이 형성되고, 이를 통해 고정체(350)는 스크류(360)의 회전방향을 따라 제1,2지지대(300, 300')의 길이방향으로 직선이동한다.In more detail, a pair of fixing pieces 340 protruding from one end of the first and second support members 300 and 300 'are formed to face each other, and the fixing pieces 340 are formed of a screw thread ( 360 is fixed to be rotatable in parallel with the longitudinal direction of the first and second support (300, 300 '). On the other hand, the fixing member 350 is formed with a nut hole 351 through which the screw 360 penetrates, through which the fixing member 350 is provided with first and second support members along the rotational direction of the screw 360. 300, 300 'in the longitudinal direction.

물론, 고정체(350)의 일면은 제1,2지지대(300, 300')와 접하므로, 스크류(360)의 회전에 의한 마찰로 회전하지 않고 스크류(360)를 따라 이동하게 된다.Of course, one surface of the fixing member 350 is in contact with the first and second support members 300 and 300 ', and thus moves along the screw 360 without rotating due to the friction caused by the rotation of the screw 360.

따라서, 관리자는 제1,2지지대(300, 300')의 인입출 정도와 길이 등에 따라 배전선(11)의 고정 위치를 조정할 수 있다.Therefore, the manager can adjust the fixed position of the distribution line 11 according to the extent of draw-out and length of the 1st, 2nd support 300,300 '.

한편, 세로방향으로 배치되는 고정체(350)는 상하 양단에 두 개의 애자(10)를 수평 회동이 가능하도록 고정시켜서, 다수 개의 배전선(11)을 일시에 연결할 수 있도록 된다.On the other hand, the fixed body 350 is arranged in the vertical direction to fix the two insulator 10 to the horizontal rotation to the upper and lower ends, it is possible to connect a plurality of distribution lines 11 at a time.

이상 설명한 구성에 따른 본 발명의 동작모습을 설명한다.The operation of the present invention according to the configuration described above will be described.

도 2(a)에 도시한 바와 같이, 제1,2지지대(300, 300')는 제1,2활차(230, 240) 사이에서 측면이 상호 맞물리도록 배치되고, 제1,2활차(230, 240)의 서브롤(232)과 기어를 매개로 맞물린다. 물론, 제1지지대(300)의 측면에 돌출 형성된 스토퍼(320)는 제2지지대(300')의 측면에 절개 형성된 가이드(330)와 맞물려서, 제1,2지지대(300, 300')의 이동범위가 가이드(330)의 길이를 벗어나지 않는다. 또한, 회전차(220)의 상면에 안착되는 제1,2지지대(300, 300')는 저면에 형성된 레일홈(301)이 회전차(220)의 상면에 형성된 레일(223)과 이동가능하게 맞물려서, 제1,2지지대(300, 300')가 탈선없이 정밀하게 이동할 수 있도록 된다.As shown in FIG. 2 (a), the first and second supports 300 and 300 'are disposed so that the side surfaces are engaged with each other between the first and second pulleys 230 and 240 and the first and second pulleys 230. , 240, the subroll 232 and the gear is engaged. Of course, the stopper 320 protruding on the side of the first support 300 is engaged with the guide 330 cut in the side of the second support 300 ', the movement of the first and second supports 300, 300' The range does not go beyond the length of the guide 330. In addition, the first and second support members 300 and 300 ′ mounted on the upper surface of the rotor wheel 220 may move the rail groove 301 formed on the lower surface thereof with the rail 223 formed on the upper vehicle wheel 220. In engagement, the first and second supports 300 and 300 'can be moved precisely without derailment.

한편, 서브롤(232)과 동축으로 회전하는 메인롤(231)은 지지 중부(120)에 형성된 내측걸림면(122)과 기어를 매개로 맞물린다.On the other hand, the main roll 231 coaxially rotating with the sub-roll 232 is engaged with the inner engaging surface 122 formed in the support middle portion 120 and the gear.

계속해서, 고온으로 인해 배전선(11)이 팽창하면, 배전선(11)이 늘어지면서 제1,2지지대(300, 300')가 받는 장력을 약화시키고, 늘어짐이 지속되면 도 2(b)에 도시한 바와 같이 상기 장력은 탄발형 회전축대(210)가 가하는 탄발력 보다 낮아져서 탄발형 회전축대(210)는 회전차(220)를 회전시키게 된다.Subsequently, when the distribution line 11 expands due to the high temperature, the distribution line 11 is stretched to weaken the tension applied to the first and second supports 300 and 300 ', and when the stretching continues, as shown in FIG. 2 (b). As described above, the tension is lower than the elastic force applied by the elastic rotary shaft 210 so that the elastic rotary shaft 210 rotates the rotary car 220.

회전차(220)가 회전하면, 회전차(220)의 상면에 입설된 제1,2활차(230, 240)도 회전차(220)를 따라 이동하는데, 이때 제1,2활차(230, 240)의 메인롤(231)은 전주 중부(120)의 내측걸림면(122)과 맞물리면서 회전하게 된다. 물론, 그 회전방향은 회전차(220)의 회전방향과 반대일 것이다.When the rotor wheel 220 rotates, the first and second pulleys 230 and 240 mounted on the upper surface of the rotor wheel 220 also move along the rotor wheel 220. In this case, the first and second pulleys 230 and 240 The main roll 231 of the) is rotated while engaging the inner engaging surface 122 of the central pole 120. Of course, the direction of rotation will be opposite to the direction of rotation of the rotary car 220.

한편, 메인롤(231)의 회전은 메인롤(231)과 동축으로 회전하는 서브롤(232)을 동일한 방향으로 회전시킨다. 이때, 서브롤(232)은 제1,2지지대(300, 300')의 걸림면(310)과 맞물리므로, 제1,2지지대(300, 300')는 서브롤(232)이 가하는 회전력에 의해 길이방향을 따라 수평으로 이동하게 된다.On the other hand, the rotation of the main roll 231 rotates the sub roll 232 coaxially rotating with the main roll 231 in the same direction. At this time, since the sub roll 232 is engaged with the engaging surface 310 of the first and second supports 300 and 300 ', the first and second supports 300 and 300' are applied to the rotational force applied by the sub roll 232. This moves horizontally along the longitudinal direction.

이러한 연동을 통해 팽창돼 늘어지는 배전선(11)은 제1,2지지대(300, 300')가 회전하면서 이를 당겨 늘어짐을 방지한다. 아울러, 제1,2지지대(300, 300')는 전주를 중심으로 회전하더라도 전주로부터 인출되면서 배전선(11)이 전주에 접근하는 것을 방지하므로, 전주와 배전선(11) 간의 접촉에 의한 전기안전사고의 발생 가능성을 방지한다.The distribution line 11 that expands and contracts through this interlock prevents the first and second supports 300 and 300 'from being pulled while rotating. In addition, since the first and second supports 300 and 300 'are rotated around the pole, the distribution line 11 is prevented from approaching the pole while being drawn from the pole, thereby causing an electrical safety accident due to contact between the pole and the distribution line 11. To prevent the possibility of occurrence.

한편, 제1,2지지대(300, 300')의 회전과는 상관없이 애자(10)는 배전선(11)을 일정한 방향으로 배선되도록 고정해야 하므로, 애자(10)는 제1,2지지대(300, 300')에 수평방향으로 회동가능하게 고정되어야 할 것이다.On the other hand, irrespective of the rotation of the first and second supports 300 and 300 ', the insulator 10 should be fixed so that the distribution line 11 is wired in a predetermined direction, so that the insulator 10 is provided with the first and second supports 300. , 300 ') should be rotatably fixed in the horizontal direction.
