본 고안은 배관연결용 플랜지 정렬지그에 관한 것으로서, 더 상세하게는 배관의 플랜지를 맞대어 볼트조립시키거나 연결된 배관의 중심이 틀어졌을 때 이를 조정하기 위한 작업을 간편하게 할 수 있도록 한 배관연결용 플랜지 정렬지그에 관 한 것이다.The present invention relates to a flange alignment jig for pipe connection, and more specifically, flange alignment for pipe connection, which simplifies the operation of bolting the pipe flanges against each other or adjusting the connected pipe when the center of the connected pipe is displaced. It is about jig.

예컨대, LNG생산기지에서 천연가스를 수요처까지 공급하기 위해서는 연결된 배관을 통해서 이루어진다. 배관을 연결하는 방법은 여러 가지 방법이 있지만, 그 중에서 플랜지를 통한 볼트체결 방법이 가장 보편적이라 할 수 있다. 특히 고압으로 이송되는 천연가스의 누출을 방지할 수 있도록 배관의 연결부위 작업이 중요하다.For example, in order to supply natural gas to a demand destination at an LNG production base, it is made through connected pipes. There are many ways to connect pipes, but the most common method is bolting through flanges. In particular, it is important to work on the pipe joints to prevent leakage of natural gas transported at high pressure.

배관의 연결부위는 초기에는 볼트의 조임상태 등이 양호하지만, 시공한지 오래된 경우에는 시간이 지남에 따라서 배관정렬이 약간씩 비틀어져 있는 것이 당연하다. Initially, the tightening condition of the bolt is good, but if the construction is long, it is natural that the pipe alignment is slightly twisted with time.

따라서 보수작업이 요구되는바, 경량의 작은 배관은 몇 가지 공구를 사용하여 정렬을 할 수 있지만, 배관 구경이 큰 중량의 배관들은 배관정렬을 잡기가 매우 어려우며 조인하기가 힘들다.As a result, maintenance is required, and lightweight pipes can be aligned using a few tools, but heavy pipes with a large pipe diameter are very difficult to align and difficult to join.

즉, 중량의 배관을 연결조립하거나 비틀어진 배관을 정렬시키는 데는 체인블럭, 지렛대 등의 기구를 사용하여야 하는 불편함이 있다.In other words, there is an inconvenience in that a chain block, a lever, or the like must be used to connect and assemble heavy pipes or align twisted pipes.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 중량의 배관을 연결하거나 정렬시 간편하게 할 수 있도록 한 배관연결용 플랜지 정렬지그를 제공하는 데 그 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a flange alignment jig for connecting pipes to facilitate the connection or alignment of heavy pipes.

상기 목적을 달성하는 본 고안은 마주 대하는 단부에 각각 결합공이 형성된 제1,2플랜지를 갖는 제1,2배관을 조립하기 위한 배관연결용 플랜지 정렬지그에 있어서,The present invention to achieve the above object in the flange alignment jig for connecting pipes for assembling the first and second pipes having the first and second flanges each having a coupling hole formed in the opposite end,

상기 제2플랜지의 적어도 2개의 인접하는 결합공에 각각 결합되는 한 쌍의 고정보스가 고정되는 수직면과, 상기 수직면으로부터 수직으로 연장되며 상기 제1플랜지의 외주면을 지지하는 적어도 2개의 조절볼트가 높이조절가능하게 나사결합되는 수평면을 구비하여 된 것을 특징으로 한다.A vertical plane to which a pair of high information beams respectively coupled to at least two adjacent coupling holes of the second flange is fixed, and at least two adjustment bolts extending vertically from the vertical plane and supporting an outer circumferential surface of the first flange; Characterized in that it has a horizontal surface that is adjustable screwed.

상기 본 고안의 특징에 의하면, 본 고안 정렬지그는 고정보스가 제2플랜지의 결합공에 결합되어 지지된 상태에서 제1플랜지가 조절볼트의 상단에 얹어지고 조절볼트의 조절로 제1플랜지가 제2플랜지와 동심으로 놓일 수 있도록 위치이동을 하게 하는 것으로서, 간편하게 제1,2배관을 동심으로 맞춰 조립 또는 정렬시킬 수 있게 한다.According to the features of the present invention, the alignment jig of the present invention is the first flange is mounted on the upper end of the adjustment bolt in a state in which the high information is coupled to and supported by the coupling hole of the second flange and the first flange is adjusted by the adjustment of the adjustment bolt. By moving the position so as to be concentric with the two flanges, it is possible to easily assemble or align the first and second pipes concentrically.

이하 첨부된 도면을 참조하면서 본 고안에 따른 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 고안 실시예의 배관연결용 플랜지 정렬지그는 예컨대, LNG생산기지에서 천연가스를 수요처까지 공급하기 위한 배관의 연결작업 또는 틀어진 배관들의 정렬을 위한 보수작업시 사용되어진다.The flange alignment jig for pipe connection of the embodiment of the present invention is used, for example, in a connection operation of pipes for supplying natural gas to a demand destination at an LNG production base or for maintenance work for alignment of misaligned pipes.

도 1을 참조하면, 상호 연결되는 제1,2배관(10)(20)의 단부에는 각각 결합공(11a)(21a)이 형성된 제1,2플랜지(11)(21)들이 마련되어 있다.Referring to FIG. 1, first and second flanges 11 and 21 having coupling holes 11a and 21a are provided at ends of the first and second pipes 10 and 20 that are connected to each other.

도 3에 도시된 바와 같은, 본 고안 실시예의 정렬지그(40)는 상호 연결되는 제1,2배관(10)(20)들이 동심(同心)으로 정렬될 수 있도록 한다.As shown in FIG. 3, the alignment jig 40 of the present invention allows the first and second pipes 10 and 20 to be interconnected to be arranged concentrically.

본 고안 실시예의 정렬지그(40)는 도 2 및 도 3을 참조하면, 상호 수직으로 연결된 수직면(41)과 수평면(42)을 갖는다.2 and 3, the alignment jig 40 of the present invention has a vertical plane 41 and a horizontal plane 42 that are vertically connected to each other.

수직면(41)에는 상기 제2플랜지(21)의 2개의 인접하는 결합공(21a)에 각각 결합되는 한 쌍의 고정보스(43)가 고정되고, 상기 수평면(42)에는 상기 제1플랜지(11)의 외주면을 지지하는 2개의 조절볼트(44)가 높이조절가능하게 나사결합되어 있다.A pair of high information screws 43 coupled to two adjacent coupling holes 21a of the second flange 21 are fixed to the vertical surface 41, and the first flange 11 to the horizontal surface 42. The two adjustment bolts 44 supporting the outer circumferential surface of the head) are screwed to adjust the height.

이와 같은 구조의 정렬지그(40)를 이용하여 제1,2배관(10)(20)을 동심으로 정렬시키는 작업은, 먼저 도 2에서와 같이 2개의 고정보스(43)를 제2플랜지(21)의 결합공(21a)에 걸어 지지시킨다.In order to align the first and second pipes 10 and 20 concentrically using the alignment jig 40 having such a structure, first, as shown in FIG. Hangs on the engaging hole 21a of the support).

이어서, 조절볼트(44)의 상단부에 제1플랜지(11)의 외주면이 지지되도록 안착시킨다. 이와 같은 상태에서 조절볼트(44)를 시계방향 또는 반시계방향으로 회전시키면서 제1플랜지(11)를 승강시켜서 제2플랜지(21)와 동심이 되도록 맞춘다.Subsequently, the outer circumferential surface of the first flange 11 is seated on the upper end of the adjustment bolt 44. In this state, while adjusting the adjusting bolt 44 in a clockwise or counterclockwise direction, the first flange 11 is lifted and adjusted to be concentric with the second flange 21.

이와 같이 제1,2배관(10)(20)이 동심이 맞추어진 상태에서 볼트(31)와 너트(32)를 체결하여 조립시킨다.In this way, the bolts 31 and the nut 32 are assembled by assembling the first and second pipes 10 and 20 in a concentric manner.

이와 같은 정렬지그(40)는 중량의 배관을 미세조정하여 간편하게 정렬 조립시킬 수 있게 한다.Such an alignment jig 40 makes it possible to easily assemble and assemble by fine-tuning the pipe of the weight.
