The invention discloses watertight gangplank door equipment for lightering operation between roll-on-roll-off ships, which comprises a gangplank door body, the gangplank door body is rotatably connected with a loading cabin, the gangplank door body is smaller than a door frame of the loading cabin, a pushing oil cylinder is arranged at the inner top of the loading cabin, and a plurality of watertight bolts are arranged inside the periphery of the door frame of the loading cabin. When the watertight bolt is ejected out, the gangplank door body can be sealed with the door frame when being closed, a movable wing plate is arranged on a platform of the loading cabin, a starting winch is arranged in the vehicle loading cabin and connected with the top of the gangplank door body through a steel wire rope, and the starting winch and the pushing oil cylinder can control the gangplank door body to be opened inwards or outwards. According to the invention, the lightering operation between two seaborne roll-on-roll-off ships is realized, the normal outward opening of the springboard door can still be met, and the wharf lightering operation and seaborne lightering operation can be simultaneously met. And the water tightness when the springboard door is closed is ensured by arranging a hinge long shaft and a watertight bolt.
本发明公开了一种用于滚装船之间过驳作业的水密跳板门设备,该水密跳板门设备包括跳板门本体,跳板门本体与装载舱转动连接,跳板门本体小于装载舱的门框,装载舱内顶设有顶推油缸,装载舱的门框四周内部设有多个水密插销,所述水密插销顶出时可使跳板门本体关闭时与门框密封,装载舱的平台上设有可活动的活动翼板,车辆装载舱内部设有启动绞车,启动绞车通过钢丝绳与跳板门本体顶部连接,启动绞车和顶推油缸可控制跳板门本体向内或向外双侧开启。本发明实现了海上两艘滚装船之间的过驳作业,仍可以满足跳板门正常的向外开启,可同时满足码头过驳作业和海上过驳作业。通过设置铰链长轴和水密插销保证跳板门关闭时的水密性。
