Ship-shore linkage loading and unloading method and system suitable for mast crane

By constructing a dynamic lifting curve compensation model and accessing real-time ship navigation and tidal information, the lifting path and attitude are adjusted, solving the lifting problem under the coupling influence of ship dynamics and tidal changes in traditional methods. This achieves vertical holding and force balance of the equipment, improving loading and unloading efficiency and safety.

AI Technical Summary

Technical Problem

In offshore docks and floating platforms, where ships are in dynamic berthing environments, traditional mast lifting and unloading methods cannot respond in real time and accurately to the coupled effects of ship dynamics and tidal changes. This can lead to equipment swaying, lifting point tilting, or uneven stress during the lifting process, potentially causing safety accidents.

Method used

By constructing a dynamic lifting curve compensation model, real-time access to ship navigation data and tidal change information is used to generate dynamic compensation parameters, adjust the lifting path and attitude, and use a variable amplitude control system to keep the lifting point vertical and the force balanced. Real-time monitoring and closed-loop feedback control are achieved by combining multi-source sensors.

Benefits of technology

It achieves vertical holding and force balance of lifting points in dynamic environments, reduces the risk of lifting accidents, improves the efficiency of ship-to-shore docking and loading/unloading, and supports the intelligent upgrading of port machinery equipment.

Abstract

The invention relates to the technical field of port machinery loading and unloading, and provides a ship-shore linkage loading and unloading method and system suitable for a mast crane. The method comprises the steps that position data, course data and attitude data of a ship are obtained in real time through ship navigation equipment, and tide height data and tide flow velocity data of the sea surface are obtained in real time through tide monitoring equipment; inputting the obtained ship position data, course data, attitude data, tidal height data and tidal flow velocity data into a control system of the mast crane; the control system generates a corresponding control instruction according to the calculated dynamic compensation parameter, and sends the control instruction to a variable amplitude control system of the mast crane; the hoisting path and the hoisting posture of the mast crane are adjusted in real time through the variable amplitude control system according to the control instruction, so that the hoisting point is kept vertical and the stress is balanced in the equipment lowering process; in the whole hoisting operation process, the operation process is monitored in real time through monitoring equipment arranged on the mast crane and the ship.
