The present invention relates to a steel chain connector for lifting a sunken hull and a lifting method thereof. The steel chain connector can be used for safe and quick lifting of the sunken hull. More specifically, the steel chain connector includes: a bracket having a chain link loop; and an anchor bolt which opens a wedge tube to be caught on the inside of the hull and not to be released therefrom. The lifting method includes the processes of: installing steel chains and nets for preventing the loss of upper and lower parts; connecting to a buoyancy line through coupling and lifting chains; installing a rail on the floor while the hull is lifted up; installing multiple buoyancy tanks through the rail; and towing the hull after lifting the hull by using the buoyancy tanks. The steel chain connector can lift the sunken hull, shorten the time needed to lift the sunken hull, prevent marine pollution, and enable a hull lifting operation to be conducted more smoothly and safely.

    본 발명은 침몰 선체를 안전하고 신속하게 인양할 수 있도록 한 침몰 선체 인양용 쇠사슬 연결구 및 인양방법에 관한 것으로서, 구체적으로는 쇠사슬 연결고리가 형성된 브래킷; 및 쐐기관이 벌어지면서 선체 내부에 걸려 빠지지 않도록 하는 앵커 볼트;를 포함하는 연결구를 구비하고, 상하부 유실방지용 쇠사슬과 유실방지용 그물을 설치하는 과정, 결속용 쇠사슬과 인양용 쇠사슬을 통해 부력선과 연결하는 과정, 상기 선체를 들어올린 상태에서 바닥에 레일을 설치하는 과정, 상기 레일을 통해 다수개의 부력 탱크를 설치하는 과정, 상기 부력 탱크를 이용하여 선체를 들어올린 후 예인하는 과정을 포함하여 침몰된 선체를 인양함에 따라, 침몰 선체의 인양 시간을 단축하고 해양 오염을 방지하는 한편, 선체의 인양이 더욱 원활하고 안전하게 이루어지는 침몰 선체 인양용 쇠사슬 연결구 및 인양방법을 제공하게 된다.
