Abstract
The utility model discloses a hydraulic lifting system. The hydraulic lifting system comprises a well; four conjugated bolt holders which arranged into a quadrangle are arranged in the well; each conjugated bolt holder is connected with two oil cylinders which drive the conjugated bolt holder to lift; the internal sides of the four conjugated bolt holders which are arranged into a quadrangle are provided with spud legs; a plurality of pin holes are uniformly arranged along the length direction of the periphery of the spud legs; each conjugated bolt holder is provided with a bolt which is driven by a bolt oil cylinder; and the bolts are matched with the pin holes. The hydraulic lifting system provided by the utility model is reasonable in structure, fast in lifting speed, strong in lifting capability, high in working efficiency, and has two times of the pre-ballast capacity two times ofthan the rated lifting capacity.
Description
Technical field
The utility model relates to a kind of hydraulic lifting system for the wind turbine installation vessel lifting.
Background technology
The wind turbine installation vessel hydraulic lifting system is the Core equipment of realizing the wind turbine installation vessel various functions, is mainly used in the lifting of wind turbine installation vessel; Make wind turbine installation vessel leave the water surface, break away from wave to the impact of lifting, reduce the work difficulty of lifting, improve precision and the efficient of lifting.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the hydraulic lifting system of favorable working performance.
Technical solution of the present utility model is:
A kind of hydraulic lifting system, it is characterized in that: comprise and enclose well, enclose and arrange four in the well and be arranged in tetragonal conjugation plug housing, each conjugation plug housing is connected with two oil cylinders that promote this conjugation plug housing lifting, four are arranged in tetragonal conjugation plug housing inboard spud leg are set, around the spud leg a plurality of pin holes are set evenly along its length, a latch that is driven by plugging pin oil cylinder is set on each conjugation plug housing, latch cooperates with pin hole.
The upper and lower side that encloses well arranges respectively up and down leg guide.
Conjugation plug housing guide piece is set in the left and right sides of conjugation plug housing.
The utility model is rational in infrastructure, and rising or falling speed is fast, and lift capability is strong; High efficiency; Pre-ballast ability is 2 times of specified hoisting capacity.
The utility model organization plan adopts the oil cylinder reversal of the natural order of things, and two oil cylinders and a conjugation plug housing join, and oil cylinder is the version of separate promotion spud leg in pairs; Line between the every pair of oil cylinder can reduce the upset moment of torsion that is attached on the conjugation plug housing like this by the neutral surface of spud leg pipe; Hydraulic part adopts many group variable twin pump fuel feeding, and the fluid control valve group has oil cylinder synchro control box and pressed adjustment control function, hydraulic system applications proportional control and digital remote control function.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the A-A view of Fig. 1.
Fig. 3 is the B-B view of Fig. 1.
The specific embodiment
A kind of hydraulic lifting system, comprise and enclose well 9, enclose and arrange four in the well and be arranged in tetragonal conjugation plug housing 10, each conjugation plug housing is connected (total has eight oil cylinders 1,2,3,4,5,6,7,8) with two oil cylinders that promote this conjugation plug housing lifting, four are arranged in tetragonal conjugation plug housing inboard spud leg 11 are set, a plurality of pin holes 12 evenly are set around the spud leg along its length, a latch 14 that is driven by plugging pin oil cylinder 13 is set on each conjugation plug housing, and latch cooperates with pin hole.
The upper and lower side that encloses well arranges respectively upper and lower leg guide 15,16.Conjugation plug housing guide piece 17 is set in the left and right sides of conjugation plug housing.
Concrete workflow is as follows;
Pile pulling/fall flow of ship journey:
Latch all meshes with the spud leg pin hole---oil cylinder 1,2,5,6 connect conjugation plug housing latch extracts---oil cylinder 1,2,5,6 stretch out promotion conjugation plug housing moves down---2 pitch-rows that drop to spud leg---oil cylinder 1,2,5,6 connect conjugation plug housing latch inserts spud leg pin hole---oil cylinder 3,4,7,8 connect conjugation plug housing latch extracts---oil cylinder 1,2,5,6 retraction pulling conjugation plug housings (drive spud leg upwards or platform moves down)---driving 2 pitch-rows of the spud leg liftings/platform decline---oil cylinder 3 that moves up, 4,7,8 connect conjugation plug housing latch inserts the spud leg pin hole, and a working cycle finishes;
Stake/rise flow of ship journey is fallen:
Latch all meshes with the spud leg pin hole---oil cylinder 3,4,7,8 connect conjugation plug housing latch extracts---oil cylinder 1,2,5,6 stretch out and promote the conjugation plug housing and move down (drive spud leg downwards or platform moves up)---2 pitch-rows of mobile spud leg---oil cylinder 3,4,7,8 connect conjugation plug housing latch inserts spud leg pin hole---oil cylinder 1,2,5,6 connect conjugation plug housing latch extracts---oil cylinder 1,2,5,6 retraction pulling conjugation plug housings move up---drive the conjugation plug housing and move 2 pitch-rows---oil cylinder 1,2,5,6 connect conjugation plug housing latch inserts the spud leg pin hole, and a working cycle finishes.
