The present invention relates to a rope cutter safety device for a ship, and is intended to protect a propulsion device by breaking a bolt fixing a rope cutter when a rope is not cut by the rope cutter. The rope cutter safety device for a ship includes a safety member disposed on at least one selected from a connection part of a fixing blade and a housing or a connection part of a rotary blade and a propulsion shaft, and allowable strength of the safety member is formed smaller than that of the propulsion shaft so that the safety member is broken to protect the propulsion device if the rope inserted between the rotary blade and the fixing blade is not cut.

    본 발명은 선박용 로프커터의 안전장치에 관한 것으로 로프가 로프커터에 의해 절단되지 않을 경우, 로프커터를 고정하는 볼트를 파단시켜 추진장치를 보호하는 것을 목적으로 한다. 고정블레이드와 하우징의 연결부분 또는 회전블레이드와 추진축의 연결부분 중 선택되는 적어도 하나에 배치되는 안전부재를 포함하고, 상기 안전부재의 허용 강도는 상기 추진축의 허용 강도보다 작게 형성되어, 상기 회전블레이드와 상기 고정블레이드 사이에 삽입되는 로프가 절단되지 않은 경우, 상기 안전부재가 파단 되어 추진장치를 보호한다.
