영구자석을 통해 반목의 중량을 부가하여 침수되도록 하는 탠덤 건조공법{TANDEM CONSTRUCTION METHOD USING MAGNETIC DEVICE}TANDEM CONSTRUCTION METHOD USING MAGNETIC DEVICE}

본 발명은 영구자석을 통해 반목의 중량을 부가하여 침수되도록 하는 탠덤 건조공법에 관한 것으로, 도크내에서 선박블록을 받쳐주는 반복을 자석을 이용하여 선박에 일체화시켜 반목의 자중이 선박에 부가되도록 함으로써, 진수선박 부양시 침수대상선박은 부양되지 않고 침수되어 진수선박이 나가면 동일 위치에서 계속 건조하여 빠른 시간 안에 도크내 선박 건조 공기를 단축시킬 수 있는 영구자석을 통해 반목의 중량을 부가하여 침수되도록 하는 탠덤 건조공법.
The present invention relates to a tandem drying method for immersion by adding the weight of banjo through a permanent magnet, by integrating the repetition supporting the ship block in the dock to the ship by using a magnet so that the weight of banjo is added to the ship When the ship is submerged, the target ship will be submerged without being buoyed, and if the ship is outgoing, the ship will continue to dry at the same location and be submerged by adding the weight of antagonist through a permanent magnet that can shorten the ship's air in the dock in a short time. Tandem drying method.

일반적으로 탠덤건조공법은, 하나의 도크에서 2척~4척의 선박을 동시에 건조할 수 있도록 하는 것으로, 선박 건조시 도크에서 완성된 선박을 부양시켜 도크 밖으로 내보낼 때 필히 부분 완성된 선박 역시 부양되도록 선작업을 한 후, 진수 선박과 함께 부양하고, 진수 선박이 도크 밖으로 나가면, 도크 게이트를 닫고 자리를 위치시킨 후 다시 물이 빠지면 이동된 위치 또는 제자리 위치에서 나머지 선박 건조작업을 진행하게 되는 공법이다.In general, the tandem drying method is to allow two to four ships to be built at the same time in one dock, and when the ship is built, the vessels that are completed in the dock must be buoyed to be partially completed. After the operation, it floats together with the launching ship, when the launching ship goes out of the dock, the dock gate is closed and the seat is placed, and when the water is drained again, the remaining ship construction work is carried out at the moved position or in place.

그러나 기존 탠덤공법의 문제점은 도크(DOCK) 제원의 제약으로 인하여 탠덤 지역(TANDEM ZONE)이 전장(LOA)대비 55%이하의 경우 부양(floating)시 선박 부상용 흘수(DRAFT, 최대7.1M)를 확보코자 탠덤 선박의 탑재물량을 제한하는 방법으로 부양을 실시하여 부양 후 도크(DOCK)내 건조공기부족으로 인한 공정차질 및 돌관작업에 따른 과다 소요공수 투입되는 문제점이 발생된다.However, the problem with the existing tandem method is that due to the limitation of the dock specification, if the tandem zone is less than 55% of the battlefield (LOA), the ship's floating draft (DRAFT, maximum 7.1M) In order to secure the loading capacity of the tandem ship, there is a problem in that the necessary amount of air is injected due to the process disruption and the stony pipe work due to the lack of dry air in the dock after the flotation.

상기 기존 탠덤 건조공법에 따른 부양전 탑재가 제한되는 미탑재물량은 주엔진(MAIN ENGINE), 꼬리 및 중간 축(TAIL & INTERMEDIATE SHAFT), 선미블록(AFT BLOCK), 래싱 브리지(LASHING BRIDGE), 해치커버(HATCH COVER) 등 이다.The unloaded volume that is limited to loading before flotation according to the existing tandem drying method is MAIN ENGINE, TAIL & INTERMEDIATE SHAFT, AFT BLOCK, LASHING BRIDGE, Hatch Cover (HATCH COVER) is.

상기와 같은 미탑재로 인해 부양이 끝난 후 도크에서 건조시의 문제점으로는 부양 후 꼬리 및 중간 축 탑재 및 주엔진(M/E) 탑재에 따른 데크 하우스(DECK HOUSE) 탑재순연으로 육상수전(SHORE POWER- 육상에서 전원을 공급받는 것)의 수전 차질이 있다는 문제점과,As a problem of drying in the dock after flotation due to the unloading as described above, the deck house (DECK HOUSE) mounted according to the tail and intermediate shaft mounting and the main engine (M / E) after the flotation is SHORE POWER. -Problems with power reception on land);

부양 후 선미블록탑재로 본견투(FINAL SIGHTING) 순연에 따른 프로펠러와 러더(PROPELLER & RUDDER) 설치공기가 부족하다는 문제점이 있다.
There is a problem that the propeller and rudder installation air is insufficient due to the stern block mounting after the stern block.

또한, 선박블록의 부양 후, 진수 선박이 도크 밖으로 나가게 되면 물을 제거하여 부양된 선박블록을 다시 작업위치로 내려놓아야 하는데, 이 경우 원래의 작업 위치나 이동위치로 선박블록을 정위치 시키는데 많은 시간과 노력이 소용된다는 문제점이 있다.In addition, after launching the ship block, if the launching ship goes out of the dock, water must be removed to lower the floated ship block back to its working position. In this case, it takes a lot of time to position the ship block back to its original working position or moving position. There is a problem that and effort is put to use.

한편 이러한 문제점을 해결하기 위하여 건조중인 선박블록을 부양시키지 않고 침수시킨 상태로 건조 완료된 선박을 인양하는 침수공법이 적용되었다.On the other hand, in order to solve this problem, the submerged method was applied to lift the vessel completed in the submerged state without raising the vessel block under construction.

그러나 이러한 침수공법은 건조중인 선박블록이 완전히 부양되지 않도록 하기 위하여 선박블록에 중량물을 탑재하거나, 바닥에 러그를 설치하여 도크 바닥에 선박을 연결하도록 구성하였으나, 중량물 탑재에 따른 작업공수가 증가되어 선박 건조 공기가 늦어지고, 러그를 설치하기 위하여 도크 바닥에 별도의 설비를 제작해야 하기 때문에 비용이 증가되는 문제점이 있다.
However, in order to prevent the ship block being built from being fully supported, the immersion method is configured to connect the ship to the dock bottom by installing a heavy load on the ship block or by installing a lug on the bottom. There is a problem that the cost is increased because the drying air is delayed, and to install a separate equipment in the dock bottom to install the lug.

상기와 같은 문제점을 해결하기 위한 본 발명의 목적은, 선박 건조시 자석을 이용하여 선박을 받쳐주는 반목을 선박과 일체화시켜 반목의 자중이 선박에 부가되도록 함으로써 진수선박 부양시 건조중인 침수대상선박 완전히 부양되지 않도록 하여 부양된 진수선박이 도크 밖으로 나가면 동일 위치에서 계속 건조하여 빠른 시간 안에 도크 내 선박 건조 공기를 단축시킬 수 있는 영구자석을 통해 반목의 중량을 부가하여 침수되도록 하는 탠덤 건조공법을 제공함에 있다.

이와 같은 본 발명은 선박을 건조시 도크 바닥에 설치되어 선박블록(20)을 받쳐주는 반목(50)이 영구자석(60)의 on/off 기능에 의해 침수대상선박(40)에 탈부착 됨으로써, 반목(50)의 중량이 침수대상선박(40)에 부가되어 종래와 같이 침수대상선박(40)을 침수시키기 위하여 침수대상선박(40)에 별도의 중량물을 설치하지 않아도 되기 때문에 중량물 탑재에 따른 작업공수가 증가되지 않고 간단한 동작만으로 침수대상선박(40)에 부가중량을 가해줄 수 있어 선박 건조 공기를 줄여줄 수 있다.Such a present invention is installed on the dock bottom when the ship is built, the anti-ship 50 for supporting the ship block 20 is detached to the immersion target ship 40 by the on / off function of the permanent magnet 60, Since the weight of 50 is added to the submerged ship 40, it is not necessary to install a separate heavy material on the submerged ship 40 to immerse the submerged ship 40 as in the prior art. It is possible to apply additional weight to the submerged ship 40 by a simple operation without increasing the ship can reduce the air drying.

또한 본 발명은 진수선박(30)의 인양 후 도크 내부에 물을 빼낼 경우 침수대상선박(40)은 최초 설치와 동일한 위치에 위치하고 있기 때문에 바로 건조 작업이 가능하여 공사기간을 단축시킬 수 있다.In addition, the present invention, if the water out of the dock after the lifting of the launching vessel 30, the submerged target ship 40 is located in the same position as the initial installation can be immediately dried construction can be shortened construction period.

한편 도 4 는 본 발명에 의한 반목에 영구자석을 설치한 상태를 나타낸 평면도로서, 반목(50)위에 2개 이상의 영구자석(60)을 설치하여 반목(50)이 보다 안정적으로 침수대상선박(40)에 부착되어 중량이 부가될 수 있도록 한다.
On the other hand, Figure 4 is a plan view showing a state in which the permanent magnet is installed on the banban according to the present invention, by installing two or more permanent magnets 60 on the banban 50, the banban 50 more immersion target ship 40 ) So that the weight can be added.

상기와 같이 구성된 본 발명에 따른 건조공법을 재차 설명하면 도크 내에 영구자석(60)이 부착되어 있는 반목(50)을 설치하고 상기 반목(50)에 받쳐지도록 선박블록(20)을 안착시켜 선박을 건조한다.Referring again to the drying method according to the present invention configured as described above to install the banban 50 is attached to the permanent magnet 60 in the dock and the ship block 20 is seated so as to be supported by the banban 50 To dry.

이때 탠덤공법의 선입선출 공정에 따라 건조가 완료된 진수선박(30)을 진수할 경우, 침수대상선박(40)을 받쳐주고 있는 반목(50)에 부착된 영구자석(60)의 레버를 on 방향으로 작동하여 자력을 발생시켜주면 반목(50)이 침수대상선박(40)의 하부에 부착되도록 함으로써, 진수선박(30)의 진수를 위해 도크 내부로 물을 유입시킬 경우 침수대상선박(40)은 반목(50)들의 중량이 부가된 상태이기 때문에 진수선박(30)의 진수를 위한 높이로 물이 유입된다 하더라도 부력에 의해 부양되지 않고 도크 바닥에 고정된다.At this time, when launching the launching ship 30, which has been dried according to the first-in first-out process of the tandem method, the lever of the permanent magnet 60 attached to the lumber 50 supporting the submerged ship 40 in the on direction. By operating to generate magnetic force so that the banmul 50 is attached to the lower part of the immersion target ship 40, when the water is introduced into the dock for launching the launching vessel 30, the immersion target ship 40 is antagonism Since the weight of the 50 is added, even if water is introduced into the height for launching the launching vessel 30, it is fixed to the bottom of the dock without being lifted by buoyancy.

이렇게 진수선박(30)이 부양되면, 인양선을 이용하여 진수선박(30)을 도크 외부로 인양한 후 도크 내부에 채워진 물을 배수한다.When the launching vessel 30 is lifted up, the launching vessel 30 is lifted to the outside of the dock by using the lifting vessel, and the water filled in the dock is drained.

물의 배수가 완료되면 도크 내부에 배치된 침수대상선박(40)의 나머지 부분을 건조한다.When the drainage of water is completed, the remaining portion of the submerged vessel 40 disposed inside the dock is dried.

아울러 침수대상선박(40)의 건조가 완료될 경우 영구자석(60)의 레버를 off 방향으로 작동하여 자력을 off 시킨 후 도크에 물을 채워 부양시킨 후 인양할 수 있도록 한다.
In addition, when the drying of the immersion target vessel 40 is completed, the lever of the permanent magnet 60 to operate in the off direction to turn off the magnetic force to be filled with water in the dock to be lifted.
