船舶自适应均衡吊运方法及吊运托架

By employing multiple independent and controllable lifting supports and a closed-loop control system on the lifting bracket, the ship's weight is rapidly and evenly distributed across the support points of the bracket, solving the problem of uneven load distribution in the underwater environment and improving the stability and safety of lifting operations.

AI Technical Summary

Technical Problem

In underwater environments, how can the multiple support points of the hoisting bracket be made to adaptively and evenly bear the weight of the ship in a balanced manner, thus solving the problems of local stress concentration on the hull and instability in hoisting operations?

Method used

A hoisting bracket with multiple independently controllable lifting supports is used. Real-time load data is obtained through pressure sensors. A closed-loop control system is used to calculate the load deviation and generate adjustment commands to adjust the height of the lifting supports until the load is balanced.

Benefits of technology

It enables rapid and balanced distribution of the ship's weight across the support points of the gantry, avoiding excessive local stress on the hull, improving the stability and safety of hoisting operations, reducing reliance on operator experience, and enhancing operational efficiency and repeatability.

Abstract

本发明公开了涉及一种船舶自适应均衡吊运方法,属于船舶工程与起重运输技术领域。该技术方案要点在于:于水下将具有多个独立可控升降的升降支墩的吊运托架介入漂浮船舶船底;操作升降支墩上升接触船底并通过压力传感器获取实时负载数据;基于该数据触发闭环控制过程,包括计算平均负载与负载偏差,当最大偏差超过第一阈值时,依据偏差方向与大小生成针对特定升降支墩的升降调整指令进行迭代调整,直至最大偏差小于更小的第二阈值,完成船舶重量向托架的均衡转移;最后将均衡后的托架连同船舶整体吊离水面。该方法主要用于在缺乏固定船坞设施的船厂,实现小型船舶安全、高效的整体下水或上坞作业。
