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
The present invention relates to a kind of Novel ocean platform crane barge system, especially a kind of have liquidate a platform crane barge system of hydraulic function of three grades of luffings and damping.
Background technology
Platform crane barge system is mainly the deck crane using on platform, be to carry out a kind of special hoisting crane of hauling operation at sea in environment, be mainly used in the vital tasks such as transportation transfer, the replenishment at sea of goods between naval vessel, the input of under-water operation equipment and recovery.Its safe reliability, can wind resistance rough water quality, maintainability, mobility and corrosion stability require very high.It has control comfort, shock-resistant, and stability is good, safe and reliable, wide to environmental conditions degree of adaptability, can work in the features such as sea situation range of instability.
Restriction because the restriction of platform specific environment, particularly stormy waves are severe, wet goods is visited at deep-sea, requires crane barge system to have the resistance to wave of wind resistance, the feature of anti-sway damping.At present, traditional platform crane barge system, can not well realize anti-sway damping, and the career field of crane barge system and load-bearing load are very limited.
Summary of the invention
The object of the invention is the defect existing for above-mentioned prior art, a kind of Novel ocean platform crane barge system authority is provided.This mechanism structure is simple, and reliable, shock-resistant, anti-sway cushioning ability is strong, and applicable operating range is wide.
The present invention relates to a kind of Novel ocean platform crane barge system.Comprise a hull, a shelf, a pedestal, a turn table, king-post, a set of main hoisting mechanism, a pair of three grades of luffings and an absorbing liquid press mechanism.Hull is fixedly connected with pedestal, and turn table is connected by revolute pair with machine base, and turn table can be done 360 ° of revolutions around its axis, and king-post is fixed on above turn table.Main hoisting mechanism consists of winch, assembly pulley, steel rope and suspension hook, and the rising that can realize suspension hook by winch lay winding wire ropes carrys out hoisting heavy.Three grades of luffings are connected with the boom system in turn table, main hoisting mechanism respectively by revolute pair with absorbing liquid press mechanism.Wherein three grades of luffings and absorbing liquid press mechanism comprise: one-level luffing absorbing liquid cylinder pressure, secondary luffing absorbing liquid cylinder pressure, three grades of luffing absorbing liquid cylinder pressures, utilize the control of damping characteristics and the flow of hydraulic actuating cylinder, made arm in wigwag motion process, greatly slow down hunting frequency and the amplitude of fluctuation of arm.
The features and advantages of the invention: the swing that three grades of luffings of a pair of symmetry and absorbing liquid press mechanism have avoided tangential wind wave action to cause.In the process being rotated at jib, because the obstacle such as ship or platform around has meticulousr requirement to the amplitude of the pitching of jib and rolling, these a pair of three grades of hydraulic damping devices can play good stabilization; And in suddenly fracture of dorsal funciculus and load is not more than in certain value situation, absorbing liquid cylinder pressure also can play certain buffer action and weight can not dropped suddenly produce unnecessary financial resources loss and personal casualty.
