Abstract

본 발명은 선박용 레이터 마스트 방진방법에 관한 것으로, 특히 마스트(mast)의 상부 또는 플렛폼 레벨(flatform level)에 웨이트(weight)를 화기작업없이 설치하여 마스트의 고유 진동수를 변화시킴으로써 선박건조에 의한 시운전시 공진으로 인한 진동이 선박의 주 항해범위에 발생하지 않도록 된 것으로 선박의 시운전시 진동계측기에 의하여 마스트의 진동값을 측정하는 제1단계와, 측정된 진동값과 일치되는 시점까지 소화전과 호스를 이용하여 마스트상의 비닐 용기에 해수를 주입하는 제2단계와, 규격화된 강판의 조합으로 된 웨이트를 해수량과 동일한 중량을 갖는 것으로 치환하여 마스트상에 보울트 및 너트로써 고정시키는 제3단계로 함을 특징으로 하는 선박용 마스트 방진방법.The present invention relates to a radar mast dustproof method for ships, and in particular, when a weight is installed on the upper part or the platform level of a mast without fire work, and when the trial operation by drying the ship by changing the natural frequency of the mast Vibration caused by resonance does not occur in the main voyage range of the ship. The first step of measuring the vibration value of the mast by the vibration measuring instrument during commissioning of the vessel, and using the fire hydrant and the hose until the point coincides with the measured vibration value A second step of injecting seawater into the mast-shaped vinyl container, and a third step of replacing the weight of the standardized steel plate with a weight equal to the amount of seawater and fixing it with bolts and nuts on the mast. Ship's mast dustproof method.

Claims (1)

선박의 시운전시 진동계측기에 의하여 마스트의 진동값을 측정하는 제1단계와, 측정된 진동값과 일치되는 시점까지 소화전과 호스를 이용하여 마스트상의 비닐용기에 해수를 주입하는 제2단계와, 규격화된 강판의 조합으로 된 훼이트를 해수량과 동일한 중량을 갖는 것으로 치환하여 마스트상에 보울트 및 너트로써 고정시키는 제3단계로 함을 특징으로 하는 선박용 마스트 방진방법.A first step of measuring the vibration value of the mast by the vibration measuring instrument during the test operation of the ship, and a second step of injecting seawater into the plastic container on the mast using a fire hydrant and a hose until a point coinciding with the measured vibration value; And a third step of fixing a bolt made of a combination of steel sheets having a weight equal to the amount of sea water and fixing the bolt with a bolt and a nut on the mast. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
