The present invention relates to a structure wherein a pillar is installed at an area in which a pipe feeder (20), a riser feeder (21), and a rotary table (24) enter over a rail (22) which is arranged around an oil well at the deck of a drilling ship. In particular, the present invention comprises: a deck pillar (30) which is accommodated to be vertically movable over a chamber (15) formed at the drilling deck (10); and an elevating means (40) which is interposed between the chamber (15) and the deck pillar (30), and causes the ascension and descension of the deck pillar (30). Therefore, a multi-purpose deck pillar is pushed up to the upper portion of the drilling deck to protrude only during use, and is folded to the lower portion of the deck to be stored at the height identical to that of the deck when the same is not in use, thereby guaranteeing a work space for a worker which is safe from the risks of confinement.

    본 발명은 시추선의 갑판에서 유정을 중심으로 배치되는 레일(22) 상으로 파이프 공급기(20), 라이저 공급기(21), 로터리테이블(24)이 출입되는 영역에 기둥을 설치한 구조에 있어서: 시추 갑판(10)에 형성되는 챔버(15) 상에 상하운동 가능하게 수용되는 갑판 기둥(30); 및 상기 챔버(15)와 갑판 기둥(30) 사이에 개재되고, 갑판 기둥(30)의 상승과 하강을 유발하는 승강수단(40);을 포함하여 이루어진다. 이에 따라, 사용시만 다목적 갑판 기둥을 시추 갑판 상부로 밀어 올려 돌출시키고 사용하지 않을 경우는 갑판 하부로 접어 갑판과 동일한 높이로 보관함으로써 협착 위험으로부터 작업자의 안전한 작업 공간을 확보하는 효과가 있다.
