애자교체작업용 송전선 인상장치{A LIFT DEVICE FOR OVERHEAD TRANSMISSION TOWER}Transmission line raising device for insulator replacement work {A LIFT DEVICE FOR OVERHEAD TRANSMISSION TOWER}

본 발명은 송전선 인상장치에 관한 것으로서, 더욱 상세하게는 송전선로를 송전탑과 일정거리로 유지시키는 기능을 하는 현수애자의 불량 발생에 따른 교체작업시 송전선을 일정 인장력을 가해 임시로 인상시켜주기 위한 인상장치에 관한 것이다.The present invention relates to a transmission line pulling apparatus, and more particularly, an impression for temporarily raising the transmission line by applying a constant tensile force during the replacement operation caused by the failure of the suspension insulator that maintains the transmission line at a certain distance from the transmission tower. Relates to a device.

일반적으로, 송전탑(10) 또는 전신주에는 도 1에 도시된 바와 같이 여러개의 송전선(30)이 애자(20)를 매개로 설치된다. 애자(20)는 절연재질로 송전선(30)과 송전탑(10)간의 거리를 일정하게 유지시켜 송전선(30)의 고압전류가 송전탑(10) 또는 전신주를 통해 방출되는 것을 차단하는 구실을 한다.In general, the transmission tower 10 or the telephone pole is provided with a plurality of transmission lines 30 via the insulator 20 as shown in FIG. The insulator 20 maintains a constant distance between the transmission line 30 and the transmission tower 10 with an insulating material to serve to block the high voltage current of the transmission line 30 from being discharged through the transmission tower 10 or the telephone pole.

이러한 애자(20)는 경질의 자기재질로 제작되어 온도와 태양광선에 강하나 취성이 강해서 강풍이나 번개 등에 의해 파손되기 쉽다. 따라서, 우리나라와 같이 태풍의 영향을 자주 받는 지역에서는 애자(20)의 교체작업이 빈번이 일어난다.The insulator 20 is made of a hard magnetic material and is resistant to temperature and sunlight, but brittle, and thus easily damaged by strong wind or lightning. Therefore, replacement work of the insulator 20 occurs frequently in an area frequently affected by a typhoon such as Korea.

그런데, 애자(20)는 전술한 바와 같이 송전선(30)을 송전탑(10)에 고정시켜주는 구실을 하므로 애자(20)에는 상당한 하중과 장력이 걸린다. 따라서 애자(20)를 교체하기 위해서는 애자(20)를 대신하여 송전선(30)의 하중과 장력을 버티어줄 송전선 인상장치가 필요하다.However, since the insulator 20 serves to fix the power transmission line 30 to the power transmission tower 10 as described above, the insulator 20 takes a considerable load and tension. Therefore, in order to replace the insulator 20, a transmission line pulling apparatus for sustaining the load and tension of the transmission line 30 in place of the insulator 20 is required.

이러한 인상장치로서 종래기술에서는 송전탑 상부요크와 사각형상의 하부요크를 연결하는 연결와이어인 와이어 행거를 레버블럭 등의 장비들과 함께 설치하게 되는데, 이때 와이어 행거가 하부요크에 감겨지는 형태로 직접 접촉됨으로 금속간의 마찰로 인한 손상발생과 가요성 부족으로 인해 설비파손 등의 안전사고가 발생될 수 있는 문제점이 있었다.
In the prior art, the wire hanger, which is a connection wire connecting the upper yoke of the transmission tower and the rectangular lower yoke, is installed together with equipment such as a lever block, and the wire hanger is wound directly on the lower yoke. There was a problem that a safety accident such as damage to the facility may occur due to the occurrence of damage and lack of flexibility due to friction between metals.

본 발명은 상기한 종래 기술에서의 문제점을 개선하기 위해 제안된 것으로서, 송전선 인상작업시 하부요크에 결합 설치가 이루어지고 상부에는 와이어 행거와의 연결이 가능한 지지구조물을 제공함으로서 보다 안정적인 송전선 인상작업이 이루어질 수 있도록 하는데 목적이 있다.The present invention has been proposed to improve the problems in the prior art as described above, by providing a support structure that is coupled to the lower yoke during the transmission line lifting operation and can be connected to the wire hanger on the upper side more stable transmission line pulling operation is The goal is to make it happen.

상기 목적을 이루기 위한 본 발명은, 애자 교체작업시 송전선을 지지하는 하부요크와 송전탑에 설치된 상부요크를 와이어 행거로 상호 연결하여 송전선의 처짐을 방지하기 위해 하부요크에 설치되는 송전선 인상장치에 있어서, 상기 인상장치는 하부요크의 양면에서 압착 결합되어질 수 있도록 2개가 쌍을 이루는 인상플레이트로 이루어지되, 상기 각 인상플레이트 상단부에는 와이어행거와 연결을 위한 앵커볼트가 체결되어질 수 있도록 앵커볼트 체결공이 형성되고; 상기 인상플레이트 하단부에는 하부요크를 사이에 두고 양측에서 상호 압착 결합되어질 수 있도록 볼트가 체결되어지는 볼트체결공이 형성된 것을 특징으로 한다.In the present invention for achieving the above object, in the transmission line lifting device installed in the lower yoke to prevent sagging of the transmission line by interconnecting the lower yoke supporting the transmission line and the upper yoke installed in the transmission tower with a wire hanger during the insulator replacement operation, The lifting device is composed of two pairs of lifting plates to be pressed on both sides of the lower yoke, the upper end of each of the lifting plate is formed with anchor bolt fastening holes to be fastened to the anchor bolt for connection with the wire hanger ; The lower end of the impression plate is characterized in that the bolt fastening hole is formed is fastened to the bolt to be mutually coupled to each other with the lower yoke between.

이러한 본 발명은, 애자교체작업시 와이어 행거와 하부요크의 연결부위에 쌍을 이루는 별도의 인상플레이트를 설치함으로서 연결부위에서 와이어 행거와 하부요크의 직접적인 마찰에 따른 손상발생을 방지함과 함께 충분한 인정력이 확보되는 효과를 나타낸다.The present invention, by installing a separate impression plate paired to the connection portion of the wire hanger and the lower yoke during the insulator replacement operation to prevent damage caused by direct friction between the wire hanger and the lower yoke at the connection portion and sufficient recognition power This shows the effect to be secured.

특히, 인상플레이트는 접촉면적이 최대화 되어질 수 있도록 일정 면적을 이루는 2개가 쌍을 이루는 형태를 이룸으로서 상호간 압착 결합력에 따른 하부요크와의 체결이 이루어지게 됨으로 보다 안정적인 결합상태가 유지되어질 수 있게 된다.In particular, the impression plate is formed in the form of a pair of two forming a certain area so that the contact area can be maximized, so that the coupling with the lower yoke according to the mutual pressing force can be maintained more stable coupling state.

이하, 본 발명의 구체적인 실시 예를 첨부 도면을 참조하여 상세히 살펴보기로 한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

먼저, 본 발명의 일 실시 예에 따른 송전선 인상장치의 설치 구조를 살펴보면, 송전탑(10)측에는 애자(20)의 상단부와 연결 지지하기 위한 삼각형 형상의 상부요크(50)가 설치되고, 애자(20)의 하단부와 연결되는 사각형상의 하부요크(40)에는 송전선(30)이 지지되어지는 통상의 송전선 지지구조에 있어서, 애자(20)의 교체작업시 일시적으로 하부요크(40)에 본 발명의 인상장치인 인상플레이트(60)를 장착하게 된다.First, looking at the installation structure of the transmission line pulling apparatus according to an embodiment of the present invention, the upper yoke 50 of the triangular shape for connecting and supporting the upper end of the insulator 20 is installed on the transmission tower 10 side, the insulator 20 In the conventional transmission line support structure in which the transmission line 30 is supported on the rectangular lower yoke 40 connected to the lower end of the upper side of the main body, the impression of the present invention is temporarily applied to the lower yoke 40 when the insulator 20 is replaced. The impression plate 60, which is a device, is mounted.

즉, 본 발명의 인상플레이트(60)는 도 4 내지 도 7에 도시된 바와 같이 역 'Y'자 형상을 이루는 2개가 한 쌍을 이루게 되는데, 각각의 상단부에는 앵커볼트(70)가 체결되어질 수 있도록 앵커볼트 체결공(63)이 형성되어져 있으며, 하단부 양측에는 상호 압착 체결을 위한 볼트가 체결되어질 수 있도록 볼트 체결공(62)이 형성되었고, 하단부 중앙에는 송전선 지지프레임(31)과 간섭을 방지하기 위한 간섭방지홈(61)이 형성되었다.That is, the impression plate 60 of the present invention, as shown in Figures 4 to 7 form a pair of two forming the inverse 'Y' shape, each of the upper end of the anchor bolt 70 can be fastened Anchor bolt fastening hole 63 is formed to be formed, and bolt fastening holes 62 are formed at both sides of the lower end so that bolts for mutual crimping fastening are formed, and at the center of the lower end, interference with the transmission line support frame 31 is prevented. An interference prevention groove 61 was formed.

특히, 인상플레이트(60)에는 상호간의 대향면에 하부요크(50)가 걸려질 수 있도록 하기 위한 돌출턱(64)이 구비되게 되는데, 이러한 돌출턱(64)은 볼트 체결공(62) 보다 높은 위치에 형성됨이 바람직하다.In particular, the impression plate 60 is provided with a projection jaw 64 to allow the lower yoke 50 to be caught on the opposite surface, the projection jaw 64 is higher than the bolt fastening hole 62 It is preferably formed in position.

한편, 인상플레이트(60) 상단의 앵커볼트 체결공(63)에 체결되는 앵커볼트(70)에는 와이어 행거(72)와의 연결을 위한 연결고리(71)가 결합 구비되어지게 된다.On the other hand, the anchor bolt 70 is fastened to the anchor bolt fastening hole 63 of the upper end of the impression plate 60 is provided with a coupling ring 71 for connection with the wire hanger 72.

도면중 미설명 부호 73은 와이어 행거(72)를 들어올리기 위한 레버블럭이고, 74는 상부요크(40)와 연결되어지는 연결체인을 각각 나타낸다.In the drawings, reference numeral 73 denotes a lever block for lifting the wire hanger 72, and 74 denotes a connection chain connected to the upper yoke 40, respectively.

이와 같은 본 발명의 송전선 인상장치인 인상플레이트(60)에 설치작업 및 설치에 따른 작용효과를 살펴보기로 한다.The effect of the installation work and installation on the impression plate 60, the transmission line lifting device of the present invention will be described.

먼저, 교체를 필요로 하는 애자(20)의 하단부에 연결된 하부요크(50)에 인상플레이트(60)를 설치하게 되는데, 이때에는 2개의 인상플레이트(60)를 하부요크(50)의 전면과 배면에 각각 위치시킨 상태에서 볼트체결이 이루어지게 된다.First, the impression plate 60 is installed on the lower yoke 50 connected to the lower end of the insulator 20 that needs replacement, in which case the two impression plates 60 are provided at the front and rear of the lower yoke 50. The bolts are made in the state positioned at each.

즉, 하부에 형성된 복수의 볼트 체결공(62)중 적절한 높이의 체결공에 볼트를 체결하게 되면 양측의 인상플레이트(60)가 하부에서 결합된 상태를 이루게 된다.That is, when the bolt is fastened to the fastening hole of the appropriate height of the plurality of bolt fastening holes 62 formed in the lower portion to form a state in which the impression plate 60 of both sides are coupled from the bottom.

이때, 인상플레이트(60) 하부 중앙에는 간섭방지홈(61)이 형성되어져 있기 때문에 하부요크(50)에 장착된 송전선 지지프레임(31)과의 간섭이 방지되어질 수 있게 된다.At this time, since the interference prevention groove 61 is formed in the lower center of the impression plate 60, the interference with the transmission line support frame 31 mounted on the lower yoke 50 can be prevented.

이와 같이 양측 인상플레이트(60)의 하부 결합이 완료되면, 인상플레이트(60) 상부의 앵커볼트 체결공(63)에 각각 앵커볼트(70)와 연결고리(71)를 설치한 후, 와이어 행거(72)와 레버블럭(73) 그리고 연결체인(74)을 각각 연결 설치한다.When the lower coupling of both of the lifting plate 60 is completed in this way, the anchor bolt 70 and the connecting ring 71 are respectively installed in the anchor bolt fastening hole 63 of the upper lifting plate 60, and then the wire hanger ( 72), the lever block 73 and the connecting chain 74 is installed respectively.

그리고, 작업자가 레버블럭(73)을 조정하여 와이어 행거(72)에 장력을 인가하게 되면 인상플레이트(60)가 상승되어지면서 하부요크(50)가 돌출부(64)에 의해 지지되는 상태를 이루게 된다.When the operator applies the tension to the wire hanger 72 by adjusting the lever block 73, the lifting plate 60 is raised to form a state in which the lower yoke 50 is supported by the protrusion 64. .

이에 따라 상부요크(40)와 하부요크(50)가 일정 인장력으로 유지되는 상태에서 불량 애자(20)를 건전한 애자로 교체 설치하는 작업을 실시하게 된다.Accordingly, in the state where the upper yoke 40 and the lower yoke 50 are maintained at a constant tensile force, the replacement of the defective insulator 20 with a healthy insulator is performed.

따라서, 기존에는 와이어 행거(72)가 직접 하부요크(50)와 연결됨으로 인한 손상 및 가요성 부족에 따란 불규칙한 유동이 발생하였으나, 본 발명에서는 인상플레이트(60)에 의한 안정적인 인상작용이 이루어지게 됨으로 작업 안전성 및 작업효율을 극대화할 수 있게 됨을 알 수 있다.Therefore, in the past, irregular flow due to damage and lack of flexibility due to the wire hanger 72 directly connected to the lower yoke 50 is generated, but in the present invention, a stable pulling action by the impression plate 60 is achieved. It can be seen that work safety and work efficiency can be maximized.

그리고, 애자 교체작업이 완료되면 본 실시 예에서의 인상플레이트(60)는 상기와 역순서로 하부요크(50)로 부터 해체하여 재사용이 가능하도록 하게 되는 것이다.
Then, when the insulator replacement operation is completed, the impression plate 60 in the present embodiment is to be disassembled from the lower yoke 50 in the reverse order to be reused.

한편, 도 8은 본 발명의 다른 실시 예에 따른 인상장치 구조를 나타낸 것이다.On the other hand, Figure 8 shows the structure of the pulling apparatus according to another embodiment of the present invention.

즉, 도시된 바와 같이 돌출턱(64) 상면 및 하부요크(50)의 저면에는 상호 치합이 가능하도록 톱니형상의 요철부(64a,50a)가 형성되고, 인상플레이트(60)에는 하부요크(50)와 면접촉 부위에 슬립 방지를 위한 우레탄코팅층(65)이 형성된 것이다.That is, as shown in the upper surface of the protruding jaw 64 and the bottom of the lower yoke 50, tooth-shaped uneven portions 64a and 50a are formed to be mutually engaged, and the lower plate 50 is formed on the impression plate 60. ) And the urethane coating layer 65 is formed to prevent the surface contact.

따라서, 인상플레이트(60)의 이상 동작시 하부요크(50)와 돌출턱(64)이 요철부(64a,50a)에 의해 상호 치합이 이루어짐과 함께 우레탄코팅층(65)에 의한 밀착이 이루어지게 됨으로 인상 과정에서 하부요크(50)가 미끄러지거나 유동되어지는 현상이 방지되어 보다 안정적인 인상 동작이 이루어지게 됨을 알 수 있다.Therefore, the lower yoke 50 and the protruding jaw 64 are engaged with each other by the uneven parts 64a and 50a during abnormal operation of the impression plate 60, and the close contact with the urethane coating layer 65 is achieved. It can be seen that the lower yoke 50 is prevented from slipping or flowing in the pulling process, thereby achieving a more stable pulling operation.

그리고, 상기에서 본 발명의 특정한 실시 예가 설명 및 도시되었지만 본 발명의 송전선 인상장치 구조가 당업자에 의해 다양하게 변형되어 실시될 수 있음은 자명한 일이다.In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the structure of the transmission line pulling apparatus of the present invention may be variously modified and implemented by those skilled in the art.

그러나, 이와 같은 변형된 실시예들은 본 발명의 기술적 사상이나 범위로부터 개별적으로 이해되어져서는 안되며, 이와 같은 변형된 실시 예들은 본 발명의 첨부된 특허청구범위 내에 포함된다 해야 할 것이다.It should be understood, however, that such modified embodiments are not to be understood individually from the spirit and scope of the invention, and such modified embodiments are intended to be included within the scope of the appended claims.
