Abstract

PURPOSE: A thruster watertight cover structure is provided to pull up a receptacle with bolting on a lifting support in a dock installation process by integrating the lifting support in the receptacle in a block assembly process. CONSTITUTION: A thruster watertight cover structure comprises a watertight cover(1), a lifting support(2), a lifting wire(3), a receptacle(4), a hull(5), a guide pipe(6), and a motor(7). The watertight cover prevents the inflow of seawater before installation of a thruster under part. The lifting support, which is removable, is integrated in the receptacle in a block assembly process and bolted in a dock installation process. The receptacle is used for installation of a thruster steering gear. The guide pipe is used for installation of the thruster under part and the cover.

Description

스러스터 워터 타이트 구조{Thruster Water Tighter Cover Structure}Thrust Water Tighter Cover Structure

본 발명은 스러스터 워터 타이트 구조에 관한 것으로 특히, 벤더 표준 타이트 커버에서 선체 블록 단계 선행 탑재시 선체 구조간의 간섭의 발생을 없앨 수 있는 제거가능한 타입의 볼팅 형태로 구조를 변경하여 리셉터클과 일체화하여 블록단계에서 탑재가능한 스러스터 워터 타이트 구조에 관한 것이다. The present invention relates to a thruster water tight structure, and in particular, the structure is changed to a bolting type of a removable type that can eliminate the occurrence of interference between the hull structures during the pre-mounting of the hull block stage in a vendor standard tight cover, and integrates the block with the receptacle. It relates to a thruster water tight structure that can be mounted in a step.

현재의 스러스트 워터 타이트 커버는 타이트 커버를 드라이 도크 혹은 언더 워터에서 단독으로 탑재, 분리가능하도록 설계되어 커버 가장자리에 도 1에 도시된 바와 같이 리프팅을 위한 서포트가 커버 웰딩 형태로 되어 있어 리셉터클에 먼저 부착후 조립시 선체 블록과 간섭의 발생으로 일체화가 불가능하게 되어 있다. The current thrust water tight cover is designed to be mounted and detached from the dry dock or underwater alone, and the support for lifting is formed in the cover welding form as shown in FIG. 1 at the cover edge so that it is attached to the receptacle first. It is impossible to integrate due to the occurrence of interference with the hull block during assembly.

스러스트 워터 타이트 커버는 rig선, drill ship에 추진 및 정위치를 유지하기 위한 스러스터를 설치전 해수가 선내로 유입되는 것을 막기 위한 커버로서, 이 커버는 드라이 도크에서 설치되면 설치 후에 선박을 진수하게 되며, 진수후 물속에서 커버를 떼어내고 스러스터를 해수속에 투입하여 선체로 탑재하게 된다. Thrust Water Tight Cover is a cover to prevent seawater from entering the ship before installation of thruster for propulsion and maintenance on the rig ship and drill ship. After launching, the cover is removed from the water and the thruster is put into the seawater to be loaded into the hull.

커버를 설치하는 방법은 여러 가지가 있으나, 기존의 설치는 리셉터클이 블록에서 설치완료 후 드라이 도크 상태에서 배 아래로 작업자가 커버를 이송 후 도 크 바닥에서 들어올려 작업했었다. 그 이유는 커버 양쪽에 서포트가 붙어있어 위에서 아래로 내릴 경우 날개 부분이 선각과 간섭 발생으로 불가능하기 때문이다. There are many ways to install the cover, but the existing installation was done by lifting the cover from the bottom of the dock after the worker transported the cover under the ship in a dry dock state after the receptacle was installed in the block. The reason for this is that the support is attached to both sides of the cover, so if the blade is lowered from the top, the wing part is impossible due to the hull angle and interference.

도 1은 도크 상태에서 와이어를 이용하여 탑재하는 종래 기술의 스러스터 워터 타이트 구조를 도시하는데, 스러스터 언더 파트 설치 전 해수유입을 방지하는 워터 타이트 커버(1), 커버를 설치하기 위한 서포트인 리프팅용 서포트(2), 커버를 설치하기 위한 와이어인 리프팅 와이어(3), 스러스터 스티어링 기어 설치를 위한 시트인 리셉터클, 선체 구조(5), 스러스터 언더파트 및 커버 설치를 위한 가이드 파이프인 가이드 파이프(6) 및 스러스터 구동을 위한 동력원으로서 모터(7)를 구비하고 있다. 1 illustrates a prior art thruster water tight structure in which a wire is mounted in a dock state, and a water tight cover 1 for preventing seawater inflow before the thruster underpart is installed, and lifting which is a support for installing the cover. Support pipe (2), lifting wire (3) for installing the cover, receptacle for seat installation for the thruster steering gear, hull structure (5), guide pipe for the installation of the thruster underpart and cover (6) and a motor (7) as a power source for thruster driving.

그런데 워터 타이트 커버(1)가 블록 단계에서 탑재시 선체 구조(5)와 간섭이 생겨 일체화하여 탑재가 불가능한 문제가 있었다. 따라서 리프팅용 서포트(2)가 다른 구조보다 돌출되어 블록 상태에서 탑재가 불가능했었다. 그러므로 다른 부품들은 블록 상태에서 조립을 완료하고, 리프팅용 서포트(2)는 드라이 도크에서 조립했었다. However, when the water tight cover 1 is mounted at the block stage, interference occurs with the hull structure 5 and thus there is a problem in that the water tight cover 1 cannot be integrated. Therefore, the lifting support 2 protruded more than other structures, and thus it was impossible to mount in the block state. Therefore, the other parts were assembled in the block state, and the lifting support 2 was assembled in the dry dock.

따라서 본 발명은 상기와 같은 배경하에서 안출된 것으로서, 타이트 커버 리프팅용 서포트를 제거가능한 타입으로 변경하여 리셉터클과 일체화하여 블록 단계에서 한번에 탑재 가능하게 한 스러스터 워터 타이트 구조를 제공하는데 그 목적이 있다. Accordingly, an object of the present invention is to provide a thruster water tight structure that can be mounted at a block stage by integrating with a receptacle by changing the support for lifting a tight cover lifting into a removable type.

상기 목적을 달성하기 위해 본 발명은 스러스터 언더 파트 설치 전 해수유입을 방지하는 워터 타이트 커버, In order to achieve the above object, the present invention provides a water tight cover for preventing the inflow of seawater before installing the thruster under parts;

According to the present invention, it is possible to obtain the effect that the lifting support can be launched by integrating with the receptacle in the block step and bolting only the support part in the docking step after mounting.

이하 도면을 참조로 하여 본 발명의 일 실시예를 설명한다. Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

도면 전체에 걸쳐서 동일 유사의 도면 부분에 대해서는 동일 유사의 도면 부호를 부여한다. Throughout the drawings, like reference numerals denote like parts throughout the drawings.

도 2는 본 발명의 스러스터 워터 타이트 구조를 도시하는데, 도 2에 있어서, 본 발명의 스러스터 워터 타이트 커버 구조는 전술한 바와 같이, 스러스터 언더 파트 설치 전 해수유입을 방지하는 워터 타이트 커버(1), 커버를 설치하기 위한 서포트인 리프팅용 서포트(2), 커버를 설치하기 위한 와이어인 리프팅 와이어(3), 스러스터 스티어링 기어 설치를 위한 시트인 리셉터클(4), 선체 구조(5), 스러스터 언더파트 및 커버 설치를 위한 가이드 파이프인 가이드 파이프(6) 및 스러스터 구동을 위한 동력원으로서 모터(7)를 구비하고 있다. Figure 2 shows the thruster water tight structure of the present invention, in Figure 2, the thruster water tight cover structure of the present invention, as described above, the water tight cover to prevent the inflow of seawater before the installation of the thruster under parts ( 1), lifting support (2) for supporting the cover, lifting wire (3) for installing the cover, receptacle (4) for seating the thruster steering gear (4), hull structure (5), A guide pipe 6, which is a guide pipe for installing the thruster underpart and a cover, and a motor 7 as a power source for driving the thruster are provided.

그러나 도 2에 도시한 바와 같이, 2A 부분은 리프팅 서포트 제거 부분으로, 블록 탑재전 분리 보관후 진수전 설치하게 되는데, 블록 상태에서 선탑재한다. 분리가능하도록 하기 위해서는 2A로 도시한 바와 같이 볼팅 타입으로 변경가능하다. 볼팅 타입의 구체적인 구성에 대해서는 당업자라면 명확히 알 수 있는 것인바 구체적으로 도시하지 않는다. However, as shown in FIG. 2, the portion 2A is a lifting support removal portion, which is installed before launching after separating and storing the block before mounting, and is preloaded in a block state. In order to be detachable, it can be changed to bolting type as shown in 2A. The specific configuration of the bolting type will be apparent to those skilled in the art and is not specifically illustrated.

도 3에 도시한 바와 같이, 블록 탑재 전에 서포트(2)를 분리한 후 보관하고, 진수 전 볼팅에 의해 설치함으로써 용이하게 본 발명의 스러스트 워터 타이트 커버를 용이하게 분리 및 설치할 수 있다. As shown in Fig. 3, the support 2 is removed and stored before the block is mounted, and the thrust water tight cover of the present invention can be easily removed and installed by installing by bolting before launching.

본 발명에 의하면, 리프팅용 서포트를 제거 타입으로 함으로써 블록단계에서 리셉터클과 일체화하여 탑재 후 도크 단계에서 서포트 부분만 볼팅하여 진수가능하게 되는 효과를 얻을 수 있다. 본 발명의 서포트 부분은 진수후 물속에서 커버를 떼어내고 스러스터를 해수속에 투입하여 선체로 탑재하게 되는 부분이므로 볼팅 타입으로 해도 강도, 기능상 문제는 전혀 없다. According to the present invention, it is possible to obtain the effect that the lifting support can be launched by integrating with the receptacle in the block step and bolting only the support part in the docking step after mounting. The support part of the present invention is a part which removes the cover from the water after launching and puts the thruster into the seawater and mounts it to the hull, so there is no problem in strength and function even when the bolting type is used.

지금까지 본 발명을 일 실시예를 참조로 하여 설명하였으나, 본 발명은 이에 한정되지 않으며, 본 발명의 영역 및 사상을 일탈하지 않는 범위 내에서 당업자에 의해 용이하게 변경 및 변형실시될 수 있으며, 이와 같은 변경 및 변형은 본 발명의 영역 내에 있는 것으로 이해되어야 할 것이다.
