Offshore platform floating crane system with three-stage amplitude-changing and shock-absorbing hedging hydraulic device

Abstract

The invention relates to an ocean platform floating crane system provided with a three-level variable amplitude and vibration-absorption hedging hydraulic device. The ocean platform floating crane system comprises a boat body, a storage rack, a base, a rotary platform, a tower column, a main hoisting mechanism, and three-level variable amplitude and vibration-absorption hydraulic mechanisms. A cantilever of the floating crane system can control the three-level variable amplitude and vibration-absorption hydraulic mechanisms in a hoisting manner so as to bear a greater load being compared with the conventional rope; the cantilever of the floating crane system resists swinging and stably controls a pair of symmetrical three-level variable amplitude and vibration-absorption hydraulic mechanisms to play the effect of a buffer; a the interference can be reduced to be minimum by bidirectional plunger piston hedging speed reduction and three-level buffering so as to play vibration-resisting and vibration-absorption effects on impact of sea wind and sea waves; and under the condition that a back rope is suddenly cracked and the valve of the load is not more than a certain value, a vibration-absorption hydraulic cylinder also can play a certain buffering effect so that a heavy object does not suddenly fall off to cause unnecessary financial resource losses and casualties. The ocean platform floating crane system disclosed by the invention has the advantages of compact structure, low gravity center, strong wind and wave resisting capability and large working space, is very suitable for a working environment of an ocean platform, and has very good popularization and application values.

Description

technical field [0001] The invention relates to a novel offshore platform floating crane system, in particular to a marine platform floating crane system with three-stage amplitude-changing and shock-absorbing and hedging hydraulic functions. Background technique [0002] The offshore platform floating crane system is mainly a marine crane used on the offshore platform. It is a special crane that performs transportation operations in the offshore environment. It is mainly used for the transportation and transfer of goods between ships, offshore replenishment, and underwater operating equipment. important tasks like recycling. Its safety and reliability, wind and sea resistance, maintainability, mobility and corrosion resistance have high requirements. It has the characteristics of convenient operation, impact resistance, good stability, safety and reliability, wide adaptability to environmental conditions, and can work in unstable sea conditions. [0003] Due to the l...

AI Technical Summary

Problems solved by technology

At present, the traditional floating crane system of offshore platforms cannot realize the anti-swing and shock absorption well, which greatly limits the working area and load-bearing load of the floating crane system.
