Abstract

The invention relates to a novel active compensation crane system which is mounted on a ship and is characterized by comprising a crane base, a lazy arm mechanism, a winch, a swing mechanism and a micro inertial navigation sensor. When the novel active compensation crane system is used for hoisting cargoes on the sea, the novel active compensation crane system measures the motion parameters of a crane including swinging and heaving through the micro inertial navigation sensor and converts the motion parameters into digital signals and transmits the digital signals to a control system for processing; the control system calculates the compensation dosages of swinging and heaving; and a servo valve controls motion of a hydraulic motor according to the processed digital signals to carry out real-time compensation on the crane subjected to swinging and heaving influence. The novel active compensation crane system can precisely and rapidly compensate the crane subjected to swinging and heaving influence, also has the cargo hoisting function to enable the crane to safely and efficiently carry out the hoisting task under the complex sea state condition, and has the characteristics of wide compensation range, high reliability and high precision and speed.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a novel active compensation crane system. Background technique [0002] Maritime replenishment is an important guarantee for the safe and efficient operation of maritime material replenishment and ship crane platforms. Due to the impact of the international economic crisis and the slowdown of global economic development, resources have become an important guarantee for the economic development of various countries. Marine resources are abundant, and high-performance marine engineering equipment has become an important tool for exploiting marine resources. With the deepening of research, marine replenishment by ships has become more and more important. Maritime replenishment is diverse. Maritime replenishment equipment includes horizontal replenishment equipment, vertical replenishment equipment, parallel replenishment equipment, and vertical replenishment equipment. [0003] Heave compensa...
