Title (EN) BALANCE-MAINTAINING CRANE AND VESSELS ON WHICH THE SAME IS MOUNTED
(FR) GRUE DE MAINTIEN D'ÉQUILIBRE ET NAVIRES SUR LESQUELS LA GRUE EST INSTALLÉE
(KO) 평형 유지 크레인 및 이를 장착한 선박
Abstract: front page image
(EN)The present invention relates to a crane which can maintain its balance regardless of the rocking of a vessel by using the concept of zero moment, and to vessels on which the same is mounted and which can load and unload cargo at sea far from land. Provided is a crane comprising: a horizontal structure which is provided in such a way as to allow a trolley to move transversely; a first column which supports the horizontal structure at a point constituting moment zero in the transverse direction; a second column which is provided at a distance from the first column and supports one end of the horizontal structure; a second support which is provided on the second column so as to allow the vertical height of the second column to be adjusted; and a base which supports the first column and the second column. By means of support using the zero moment point, the present invention allows precise balance control because balance can be maintained even without applying substantial force to a hydraulic cylinder.
(FR)La présente invention concerne une grue pouvant maintenir son équilibre, quel que soit le tangage d'un navire, en utilisant le concept de moment cinétique nul. Elle concerne également des navires sur lesquels la grue est installée et qui peuvent charger ou décharger une cargaison en pleine mer. La grue de l’invention comprend: une structure horizontale conçue de façon à permettre un mouvement transversal d'un chariot; une première colonne portant la structure horizontale en un point qui constitue le moment cinétique nul dans le sens transversal; une seconde colonne éloignée de la première colonne et portant une extrémité de la structure horizontale; un second support disposé sur la seconde colonne de façon à permettre le réglage de la dimension verticale de la seconde colonne; et un socle portant la première et la seconde colonne. L'utilisation d'un support exploitant le moment cinétique nul garantit un réglage d'équilibre précis permettant de maintenir l'équilibre même sans application d'une force importante sur un cylindre hydraulique.
(KO)본 발명은, 제로 모멘트의 개념을 이용하여 선박의 요동에 관계없이 평형을 유지할 수 있는 크레인 및 이를 장착하여 육지로부터 떨어진 해상에서 화물을 하역할 수 있는 선박에 관한 것이다. 본 발명은, 트롤리가 횡방향으로 이송 가능하게 설치되는 수평 구조물과, 상기 수평 구조물을 횡방향 모멘트가 제로가 되는 지점에서 지지하는 제1 기둥과, 상기 제1 기둥과 간격을 두고 설치되어 상기 수평 구조물의 일단을 지지하는 제2 기둥과, 상기 제2 기둥에 구비되어 상기 제2 기둥의 상하방향 높이 조절이 가능하도록 하는 제2 지지대와, 상기 제1 기둥과 상기 제2 기둥을 지지하는 베이스를 포함하는 크레인을 제공한다. 본 발명은 제로 모멘트 포인트에 의한 지지를 통하여 유압 실린더에 큰 힘을 가하지 않고서도 평형을 유지할 수 있도록 하기 때문에 정밀한 평형 제어가 가능하게 된다.
