The invention discloses a method for quickly balancing the buoyancy of a ship during roll-on and roll-off of oversized goods transported by a waterway, which is characterized in that in the roll-on and roll-off process of the oversized goods, ballast water is not regulated and discharged for the ship, and the buoyancy of the ship is quickly balanced according to the pre-measured upward lifting force required by the ship near the shore side and the torque change value in the roll-on and roll-off process. Upward external force is applied to the shore-approaching side of the ship, the buoyancy change of the shore-approaching side of the ship in the roll-on and roll-off process is balanced in real time, and the height difference between the shore-approaching side of the ship and the base plane of the unloading platform is always kept within the roll-on and roll-off range for oversized goods. Namely, according to the lever principle, in the roll-on roll-off process of the oversized goods, the side, close to the shore, of the ship is pried upwards with relatively small external force, and the buoyancy change of the side, close to the shore, of the ship is balanced in time, so that the oversized goods can move without stop in the roll-on roll-off process, and roll-on roll-off of the oversized goods can be rapidly conducted; and therefore, the roll-roll loading and roll-roll unloading operation time of oversized goods is greatly shortened.
本发明公开了一种水路运输超大货物滚装滚卸时船舶浮力的快速平衡方法,在超大货物的滚装滚卸过程中,不对船舶进行调排压载水,根据预先测算的船舶靠岸侧所需的向上吊力及滚装滚卸过程中力矩的变化值,对船舶的靠岸侧施加往上的外力,即时平衡船舶靠岸侧在滚装滚卸过程中的浮力变化,使得船舶靠岸侧与卸货平台基面之间的高度差一直保持于在可供超大货物进行滚装滚卸的范围内。即是说,本发明利用杠杆原理,在超大货物的滚装滚卸过程中,用相对较小的外力往上撬动船舶的靠岸侧,即时平衡船舶靠岸侧的浮力变化,从而在滚装滚卸过程中,超大货物可以不停顿地移动,从而能快速进行超大货物的滚装滚卸,进而大大缩短了超大货物的滚装滚卸操作时间。
