Abstract
Description
【発明の詳細な説明】 本発明は船舶等のトリム装置に関する。[Detailed description of the invention] The present invention relates to a trim device for ships and the like.

す、またバラストタンク内の自由水によりGMが低下し
て船の安定性能に悪影響を与えている。For example, in conventional icebreakers, as shown in the side view of Figure 1, the hull is trimmed with seawater ballast and the ice IC is removed.
Because the ship breaks the ice by lifting the hull SH on top, it takes a considerable amount of time to move several hundred tons of seawater between the bow ballast tank and the stern ballast tank.
Additionally, free water in the ballast tank reduces GM, which has a negative impact on the ship's stability.

とを具えたことを特徴とする。The present invention was proposed in view of the above circumstances, and aims to provide a trim device for a ship, etc. that can quickly trim without impairing the stability of the ship. It is characterized by comprising a solid ballast attached to the bow side and/or the stern side of the upper surface of the heavy bottom, and means for moving the solid ballast to a desired position along a rail laid in the stern direction. .

.. Reduction gear 5, reduction gear 6. A motor 7 is assembled into a frame 8. Reference numeral 9 is connected to the frame 8 by a solid ballast made by storing something with a large specific gravity, such as iron scrap, in a steel box. 10 is a rack installed in the bow and stern portions of the double bottom 2 or on the upper surface of the double bottom 2 in the direction of the centerline; 11;
13.13 is a roller (or wheel) inserted between the lower surface of solid ballast 9 and the upper surface of parallel rail 12, which will be described later.
are guide rails laid parallel to the outside of the parallel rails 12 and 12, respectively, to prevent the solid ballast 9 from lateral vibration during movement; Reduction gear 5. Reducer 6. The motor 7 and the frame 8 cooperate to constitute the drive device 3.
