러더 혼 블록 이동용 러그{a lug for rudder horn block}Rug for Rudder Horn Blocks {a lug for rudder horn block}

본 발명은 블록용 러그에 관한 것으로서, 선박의 건조과정에서 블록을 크레인에 연결시키기 위해서 블록에 설치되는 러그에 관한 것이다.The present invention relates to a lug for a block, and relates to a lug installed in a block in order to connect the block to a crane in a ship construction process.

선박 건조 과정은 선박 전체를 여러 개의 대형 블록으로 나누어 제작한 후 이들을 쌓고 연결하는 탑재 과정을 거쳐 선박을 완성하게 되며, 이러한 대형 블록의 탑재 공정에서는 대형 크레인을 사용하게 된다.The ship construction process is made by dividing the whole vessel into several large blocks, and then stacking and connecting them to complete the vessel, and the large crane is used in the mounting process of these large blocks.

따라서, 선박 블록을 크레인으로 들어올리거나 이동시키기 위해서는 블록에 크레인을 안전하게 연결할 수 있는 부분이 필요하게 된다.Therefore, in order to lift or move the ship block to the crane, there is a need for a part that can safely connect the crane to the block.

즉, 연결 부분을 만들기 위해 각 블록에는 적절한 위치에 필요한 수 만큼의 러그(lug)를 설치하게 되고, 러그는 별도로 제작하여 필요한 부위에 용접한 후 이 부분에 크레인의 훅을 걸어 블록을 운반하게 된다.That is, in order to make a connection part, as many lugs as necessary are installed in each block at an appropriate position, and the lugs are manufactured separately and welded to the required parts, and then the hooks of the crane are carried on the parts to carry the blocks. .

일반적인 러그는 도 1에 도시된 바와 같이 상부에 크레인의 훅을 삽입하기 위한 걸림공(2)이 형성되며, 양면에는 러그(1)가 선박의 하중에 의해 블록에서 분리되는 것을 방지하도록 복수 개의 리브(3)를 설치하게 된다.As shown in FIG. 1, a general lug has a catching hole 2 for inserting a hook of a crane at an upper portion thereof, and a plurality of ribs on both sides thereof to prevent the lug 1 from being separated from a block by a load of a ship. (3) will be installed.

이러한 러그(1)는 블록의 탑재과정을 모두 끝마친 후에는 블록의 손상 방지 및 높게 돌출됨으로 작업자들이 걸리면서 안전사고가 발생되는 것을 방지하기 위해 블럭에서 다시 제거하게 된다.The lug 1 is removed from the block again in order to prevent the occurrence of a safety accident while the workers are caught by preventing damage of the block and protruding high after finishing the mounting process of the block.

구체적으로는 블록에 용접된 러그의 하단부로부터 15mm~30mm를 남기고 산소 절단하는 공정을 거치고, 남은 러그의 하단부를 가공하는 밀링 과정, 절삭유 및 칩의 제거 등과 같은 여러 가지 마무리 공정이 요구된다.Specifically, various finishing processes such as a milling process for processing the lower end of the remaining lug, a removal of cutting oil and chips, and the like are required after the process of oxygen cutting leaving 15 mm to 30 mm from the lower end of the lug welded to the block.

또한, 선박 블록은 그 조립되는 위치에 따라서 다양한 형태를 갖추게 되고, 그 무게 중심 등이 다르므로 각 선박 블록에 맞게 러그의 위치 및 형태가 결정된다.In addition, the ship block has a variety of forms according to the assembly position thereof, since the center of gravity and the like is different, the position and shape of the lug is determined according to each ship block.

특히, 방향타(rudder)가 설치되는 러더 혼 블록(rudder horn block)은 그 형태가 다른 블록보다 특이하고, 블록을 조립하기 위해서는 이동 과정에서 180˚로 회전시켜야 하는 경우가 있다.In particular, the rudder horn block in which the rudder is installed is unusual in form than other blocks, and in order to assemble the block, the rudder horn block may need to be rotated by 180 ° in the moving process.

그러나, 종래의 러그는 크레인의 훅 또는 와이어가 회전과정에서 파손되거나, 구조적으로 회전이 불가능하다는 사용상의 문제점이 있다.However, the conventional lug has a problem in use that the hook or wire of the crane is broken in the rotation process, or structurally impossible to rotate.

본 발명은 상기의 문제점들을 해결하기 위해서 안출된 것으로서, 본 발명은 러더 혼 블록을 조립하기 위하여 이동하는 과정에서 회전이 가능한 러그를 제공하는 데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a lug that can be rotated during the movement to assemble the rudder horn block.
