Description

구형탱크의 볼피스 용접용 지그장치{Jig apparatus for ball piece of ball tank}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a ball-

본 발명은 구형탱크의 볼피스 용접용 지그장치에 대한 것으로서, 더욱 상세하게는 지상에서 용접면을 수평으로 유지시켜 용접을 할 수 있게 하는 구형탱크의 볼피스 용접용 지그장치에 대한 것이다.The present invention relates to a jig for ball-piece welding of a spherical tank, and more particularly, to a jig for ball-piece welding in a spherical tank that enables welding by holding the welding surface horizontally on the ground.

구형탱크는 고압의 유체를 저장하는 볼 형상의 탱크로서, 그 직경이 16m 내지 27m 가량된다. 구형탱크를 만드는 작업장과 설치장소는 대게 멀리 떨어져 있어서, 작업장에서 구형탱크를 만든 후 선박 등을 사용하여 설치장소로 구형탱크가 이송된다. 그런데 구형탱크는 그 규모가 방대하여 작업장에서 완전히 조립된 경우 이를 운송할 수 있는 방법이 없었다. 그래서 종래에는 작업장에서 구형탱크의 각각의 볼피스를 만든 후 설치장소로 이동하여, 설치장소에서 볼피스들을 용접하여 구형탱크를 완성하였다.The spherical tank is a ball-shaped tank for storing a high-pressure fluid and has a diameter of 16 to 27 m. The workshop and the installation site where the old tank is made are usually far away, so that a spherical tank is made in the workplace and then the old tank is transferred to the installation site by using a ship or the like. However, the old tank was so large that there was no way to transport it when it was fully assembled in the workplace. Therefore, conventionally, each ball piece of the spherical tank was made in the workplace, and then moved to the installation site, and the ball pieces were welded at the installation site to complete the spherical tank.

즉 종래에는 도 5 내지 도 7에 도시된 바와 같이 설치장소에서 구형탱크를 완성하였다. 먼저 도 5에 도시된 바와 같이 구형탱크를 지지할 컬럼(1)에 볼피스(3)를 결합시킨 후 이를 설치장소에 설치한다. 그리고 도 6에 도시된 바와 같이 컬럼(1)에 결합된 볼피스(3) 사이에 다른 볼피스(5)를 위치시킨 후 볼피스(3, 5)들을 서로 용접한다. 그리고 도 7과 같이 나머지 볼피스들을 용접하여 구형탱크를 완성한다.That is, conventionally, as shown in FIGS. 5 to 7, a spherical tank is completed at the installation site. First, as shown in FIG. 5, the ball piece 3 is coupled to the column 1 for supporting the spherical tank, and then the ball piece 3 is installed in the installation site. 6, the other ball pieces 5 are positioned between the ball pieces 3 connected to the column 1, and then the ball pieces 3, 5 are welded to each other. Then, the remaining ball pieces are welded as shown in FIG. 7 to complete the spherical tank.

도 5 내지 도 7과 같이 볼피스들을 용접하기 위해서 먼저 구형탱크 주변에 작업자가 작업할 수 있는 작업대를 설치한 후 작업자가 작업대에서 용접작업을 한다. 이때 종래에는 구형탱크를 설치하기 위해서 모든 볼피스들을 작업대에 올라가서 공중에서 용접한다. 한편 볼피스들은 직선으로 형성되는 것이 아니라 곡선으로 형성되므로 볼피스를 따라 용접하면 그 용접면의 각도가 계속 변하게 된다. 따라서 모든 볼피스들을 공중에서 작업대에 올라가서 용접하므로 용접조건이 까다로워서 구형탱크를 조립하는데 시간 및 노동력이 많이 필요하다는 문제점이 있었다.As shown in FIGS. 5 to 7, in order to weld the ball pieces, a workbench is installed around the spherical tank so that the worker can work the workpiece, and then the worker performs welding work on the workbench. At this time, in order to install a spherical tank, all the ball pieces are climbed on the work table and welded in the air. On the other hand, since the ball pieces are formed by curves rather than being formed in a straight line, when the ball pieces are welded along the ball pieces, the angle of the welding surface continuously changes. Therefore, since all the ball pieces are welded on the work table in the air, the welding conditions are complicated, and there is a problem in that it takes much time and labor to assemble the spherical tanks.

본 발명은 상기의 문제점을 해결하기 위한 것이다. 본 발명은 한 쌍의 볼피스를 지상에서 용접하여 구형탱크의 조립시간을 줄일 수 있는 구형탱크의 볼피스 용접용 지그장치를 제공하는 것을 목적으로 한다.The present invention is intended to solve the above problems. An object of the present invention is to provide a jig for ball piece welding of a spherical tank in which a pair of ball pieces are welded on the ground to reduce the assembling time of the spherical tank.

본 발명에 따른 구형탱크의 볼피스 용접용 지그장치는 지그와 각도조절수단을 포함한다. 상기 지그는 복수의 볼피스를 서로 맞대어서 거치시킬 수 있다. 또한 상기의 각도조절수단은 상기 지그의 수평각도를 조절할 수 있다.The ball-piece welding jig apparatus for a spherical tank according to the present invention includes a jig and an angle adjusting means. The jig can mount a plurality of ball pieces against each other. Further, the angle adjusting means can adjust the horizontal angle of the jig.

또한, 상기의 볼피스 용접용 지그장치에 있어서, 상기 각도조절수단은 베이스프레임과, 지지컬럼과, 제1실린더부재와, 제2실린더부재를 구비하는 것이 바람직하다. 상기 지지컬럼은 일단은 베이스프레임과 고정결합되고 타단은 상기 지그에 힌지결합되어 상기 지그를 받친다. 상기 제1실린더부재는 상기 지지컬럼의 일측편에서 일단은 상기 베이스프레임과 결합되고 타단은 상기 지그에 결합되어 신축가능하다. 상기 제2실린더부재는 상기 지지컬럼의 타측편에서 일단은 상기 베이스프레임과 결합되고 타단은 상기 지그에 결합되어 신축가능하다.In the above-described jig for a ball-piece welding, it is preferable that the angle adjusting means includes a base frame, a support column, a first cylinder member, and a second cylinder member. The support column has one end fixedly coupled to the base frame and the other end hinged to the jig to support the jig. The first cylinder member has one end of the support column coupled to the base frame and the other end coupled to the jig to expand and contract. The second cylinder member is extendable from the other side of the support column at one end to the base frame and at the other end to the jig.

본 발명에 의하면 설치장소의 지상에서 한 쌍의 볼피스를 용접할 수 있다. 이때 볼피스의 용접면을 수평으로 유지하면서 용접할 수 있다. 따라서 볼피스의 용접을 용이하게 할 수 있다.According to the present invention, a pair of ball pieces can be welded on the ground at the installation site. At this time, welding can be performed while keeping the welding face of the ball piece horizontal. Therefore, welding of the ball piece can be facilitated.

또한, 본 발명에 의하면, 지상에서 한 쌍의 볼피스를 용접하므로 구형탱크 조립시 조립시간을 단축시킬 수 있다.Further, according to the present invention, since a pair of ball pieces are welded on the ground, the assembling time can be shortened in assembling the spherical tank.

도 1 내지 도 3을 참조하여 본 발명에 따른 구형탱크의 볼피스 용접용 지그장치의 일 실시예를 설명한다.1 to 3, an embodiment of a ball-piece welding jig apparatus for a spherical tank according to the present invention will be described.

본 발명에 따른 볼피스 용접용 지그장치는 지그(20)와, 각도조절수단(30)을 포함한다.The ball piece welding jig apparatus according to the present invention includes a jig (20) and an angle adjusting means (30).

지그(20)는 복수의 볼피스(51, 53)를 서로 맞대어서 거치시킬 수 있다. 지그(20)는 볼피스(51, 53)를 올려놓을 수 있도록 볼피스(51, 53)와 동일한 곡률로 형성된다. 본 실시예의 경우 지그(20)는 2개의 볼피스(51, 53)를 서로 맞대어 올려놓는다.The jig 20 can hold a plurality of ball pieces 51, 53 against each other. The jig 20 is formed with the same curvature as that of the ball pieces 51 and 53 so that the ball pieces 51 and 53 can be placed thereon. In this embodiment, the jig 20 puts the two ball pieces 51, 53 against each other.

각도조절수단(30)은 지그(20)의 수평각도를 조절하는 역할을 한다. 이를 위하여 각도조절수단(30)은 베이스프레임(31)과, 지지컬럼(33)과, 제1실린더부재(35)와, 제2실린더부재(37)를 구비한다.The angle adjusting means 30 serves to adjust the horizontal angle of the jig 20. To this end, the angle adjusting means 30 includes a base frame 31, a support column 33, a first cylinder member 35 and a second cylinder member 37.

지지컬럼(33)은 일단(33a)은 베이스프레임(31)에 고정결합되고 타단(33b)은 지그(20)의 중앙부에 힌지결합되어 지그(20)를 지지한다.One end 33a of the support column 33 is fixedly coupled to the base frame 31 and the other end 33b is hinged to the center of the jig 20 to support the jig 20. [

제1실린더부재(35)는 신축될 수 있으며, 지지컬럼(33)의 좌측편에서 일단은 베이스프레임(31)에 결합되고 타단은 지그(20)에 결합된다.The first cylinder member 35 can be expanded and contracted and one end of the support column 33 is coupled to the base frame 31 and the other end is coupled to the jig 20 on the left side.

제2실린더부재(37)은 신축될 수 있으며, 지지컬럼(33)의 우측편에서 일단은 베이스프레임(31)에 결합되고 타단은 지그(20)에 결합된다.The second cylinder member 37 can be expanded and contracted and one end of the support column 33 is coupled to the base frame 31 and the other end is coupled to the jig 20.

그래서 제1실린더부재(35) 및 제2실린더부재(35)를 신축시켜서 지지컬럼(33)의 각도를 조절할 수 있다.Thus, the angle of the support column 33 can be adjusted by expanding and contracting the first cylinder member 35 and the second cylinder member 35.

본 실시예의 지그(20)에 2개의 볼피스(51, 53)를 서로 맞대어 올려놓는다. 그러면 지상에서 작업자가 2개의 볼피스(51, 53)의 접촉부(55)를 용접할 수 있다. 이때 볼피스(51, 53)는 곡률을 형성하므로 그 접촉부(55)가 지상에 평행하게 놓여지지 않는다. 이 경우 각도를 가지므로 작업자가 용접하기 불편하다. 그래서 도 3의 (a)와 같이 제2실린더부재(37)를 신장시키고 제1실린더부재(35)를 축소시키면 접촉부(55a)가 지상에 수평을 유지한다. 그리고 제2실린더부재(37)를 점점 축소시키고 제1실린더부재(35)를 점점 신장시키면 결국 도 3의(b)와 같이 접촉부(55b)가 지상에 수평을 유지한다. 즉 제1실린더부재(35) 및 제2실린더부재(37)를 신축시키면 모든 접촉부(55)를 수평으로 위치시킬 수 있으므로 수평의 상태에서 접촉부(55)를 용접할 수 있다. 그래서 작업자가 2개의 볼피스(51, 53)를 신속하게 용접할 수 있다. 2개의 볼피스(51, 53)가 용접되면 이를 조립하여 구형탱크를 완성할 수 있다. 그래서 종래에는 각각의 볼피스를 공중에서 용접하였으나, 본 실시예의 경우 2개의 볼피스를 각각 지상에서 용접한 후 이를 공중에서 용접하므로 용접시간을 줄일 수 있다. Two ball pieces 51, 53 are put on the jig 20 of this embodiment against each other. Then, the operator can weld the contact portions 55 of the two ball pieces 51, 53 on the ground. At this time, since the ball pieces 51 and 53 form a curvature, the contact portion 55 is not placed parallel to the ground. In this case, it is inconvenient for an operator to weld since it has an angle. 3 (a), when the second cylinder member 37 is stretched and the first cylinder member 35 is contracted, the abutting portion 55a is kept horizontal on the ground. When the second cylinder member 37 is gradually reduced and the first cylinder member 35 is gradually elongated, the contact portion 55b is kept horizontal on the ground as shown in FIG. 3 (b). That is, when the first cylinder member 35 and the second cylinder member 37 are expanded and contracted, all the contact portions 55 can be positioned horizontally, so that the contact portions 55 can be welded in a horizontal state. Thus, the operator can quickly weld the two ball pieces 51, 53. When two ball pieces 51 and 53 are welded, they can be assembled to complete a spherical tank. Therefore, in the conventional art, the ball pieces are welded in air, but in the case of the present embodiment, the welding time can be reduced because two ball pieces are welded on the ground and then welded in air.

도 4는 본 발명에 따른 구형탱크의 볼피스 용접용 지그장치의 다른 실시예이다. 도 4에 도시된 실시예의 경우 지그(22)가 도 1에 도시된 실시예와 반대로 각도조절수단(30)에 결합되어 있다. 도 1에 도시된 실시예의 경우 볼피스의 외주면을 용접할 수 있지만 도 4에 도시도니 실시예는 볼피스의 내주면을 용접할 수 있다.4 is another embodiment of a jig for welding a ball piece of a spherical tank according to the present invention. In the embodiment shown in FIG. 4, the jig 22 is coupled to the angle adjusting means 30, as opposed to the embodiment shown in FIG. In the embodiment shown in FIG. 1, the outer circumferential surface of the ball piece can be welded, but in the embodiment shown in FIG. 4, the inner circumferential surface of the ball piece can be welded.
