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 mainly is the deck crane that uses at platform, be a kind of special hoisting crane of carrying out hauling operation at sea in the environment, be mainly used in the vital tasks such as the input of transportation transfer, replenishment at sea, under-water operation equipment of goods between the naval vessel and recovery.It is very high that but its safe reliability wind resistance rough water quality, maintainability, mobility and corrosion stability require.It has control comfort, and is shock-resistant, and stability is good, and is safe and reliable, wide to the environmental conditions degree of adaptability, can work in the characteristics such as sea situation range of instability.
Because the restriction that the restriction, particularly stormy waves of platform specific environment are abominable, wet goods is visited at the deep-sea requires the crane barge system to have the anti-wave of wind resistance, the characteristics of anti-sway damping.At present, traditional platform crane barge system can not well realize anti-sway damping, so that the career field of crane barge system and load-bearing load are very limited.
Summary of the invention
The objective of the invention is the defective for above-mentioned prior art existence, 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, shelf, pedestal, turn table, king-post, cover main hoisting mechanism, a pair of three grades of luffings and an absorbing liquid press mechanism.Hull is captiveed joint with pedestal, and turn table is connected revolute pair with machine base and connects, and turn table can be done 360 ° of revolutions around its axis, and king-post is fixed on above the turn table.Main hoisting mechanism is made of winch, assembly pulley, steel rope and suspension hook, can realize that by the winch lay winding wire ropes rising of suspension hook comes hoisting heavy.Three grades of luffings and absorbing liquid press mechanism link to each other with boom system in turn table, the main hoisting mechanism respectively by revolute pair.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, utilized the control of damping characteristics and the flow of hydraulic actuating cylinder, so that arm slows down hunting frequency and the amplitude of fluctuation of arm greatly in the wigwag motion process.
Characteristics of the present invention and advantage: 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 that jib is rotated, because the obstacle such as ship or platform has meticulousr requirement to the pitching of jib and the amplitude of rolling on every side, 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 the certain value situation, the absorbing liquid cylinder pressure also can play certain buffer action and produce unnecessary financial resources loss and personal casualty so that weight can not drop suddenly.
