The specific embodiment
A kind of multi-functional wind-powered electricity generation erecting stage that embodiments of the invention provided is installation or other ocean engineering device waterborne and the various main equipment lifting in bank task that is mainly used in the coastal waters wind power equipment.This platform both can be used as crane barge and use, also can be in the about 30 meters scopes of the depth of water marine site, argillo arenaceous seabed or similar marine site carry out operation by the jack-up platform pattern.
Fig. 1 is the front view of the wind-powered electricity generation erecting stage of one embodiment of the invention.With reference to shown in Figure 1, platform comprises hull 1, lifting catch gear 2, spud leg 3, hoisting crane 4, main generator 5, pile holding device 6 and drive hammer 7 etc.
Spud leg 3 is provided with four, to extending below, is provided with shoe 3.1 in the spud leg lower end from the bottom surface of hull 1.Be to guarantee the balance of hull 1, four pile legs 3 all are positioned at 15.6 meters, line of centers both sides along the line of centers of hull 1 symmetry in twos, and back spud leg line of centers is apart from 7.8 meters of hull 1 tail ends, and spud leg is apart 44.4 meters behind two preceding spud legs and two.67.0 meters of the length overalls of each spud leg, the shoe of spud leg lower end are the square body of 9.4 meters of the length of sides, highly are 2.2 meters.
Lifting catch gear 2 is located on the deck of hull 1.The rack-and-gear lifting function that lifting catch gear 2 has can make hull 1 off sea the specified altitude assignment of climbing.
As way of illustration but not limitation, hull 1 is unpowered, is tied up by tugboat during towage and drags or drag by barge is dried.Hull 1 insert seabed, operation marine site through platform deadweight precompressed spud leg 3, thereby fixed hull is carried out operation according to the jack-up platform pattern through 2 liftings of lifting catch gear.Spud leg 3 can be set to moving up and down, can be retracted to fully in the hull, carries out operation according to the crane barge pattern.
The main deck of hull 1 has been equipped with four positioning anchors (scheming not shown), two anchor dual-purpose navigation of stem anchor.
Hull 1 relies on off sea the specified altitude assignment of climbing that move up and down of 2 pairs of spud legs of lifting catch gear.Lifting catch gear 2 is positioned at 4 angles of hull; After hull arrives appointment marine site, coastal waters; Spud leg 3 inserts the seabed certain depth through the rack-and-gear variable-frequency motor driver train of lifting catch gear 2, and the hull jacking is gone out water surface specified altitude assignment; The catch gear of being made up of hydraulic ram is fixed on the spud leg specified altitude assignment with hull; Thereby hull leaves the sea level certain altitude, for offshore construction provides stable job platform as the similar land, to eliminate the influence of marine stormy waves stream to equipment availability precision such as hoisting cranes.This lifting catch gear 2 can use Chinese patent ZL 200920210266.3 and lifting mechanism and catch gear that ZL200920075042.6 disclosed.
Hoisting crane 4 is positioned on the line of centers of hull 1, according to 7.8 meters of the afterbodys of hull 1.In the present embodiment, the maximum load-carrying ability of hoisting crane 4 is 800 tons.For instance, can be equipped with two gib heads, 400 tons of each gib head lift heavys; Two main hooks can carry out lift heavy simultaneously, also can carry out lift heavy respectively.Preferably, hoisting crane 4 is the full circle swinging hoisting crane, can realize 360 full circle swinging operation.The maximum sling height of hoisting crane 4 can reach 110 meters, and the maximum operation radius is 28 meters.
Full ship is equipped with main generator 5, is used to hoisting crane 4 power supplies.In the embodiment of Fig. 2, main generator 5 has four 5.1,5.2,5.3,5.4.Three electrical generators use simultaneously during hoisting operation, and one subsequent use.
Drive hammer 7 is located on the deck of hull 1, and is movably located in the scope of work of hoisting crane 4.Drive hammer 7 is the major diameter hydraulic impact hammer of 800KJ blow energy, can realize 4.5-5.1m major diameter single pile piling function.
Pile holding device 6 is located at the deck flange of hull 1, and is in the scope of work of hoisting crane 4.Hoisting crane 4 can hang pile holding device 6 places with drive hammer 7 and implement piling work.
Pile holding device 6 is configured to have correction and centralizing system, can realize the correction of X, Y direction ± 1m scope, guarantees to drive piles squareness in 4/1000ths.The correction of this pile holding device 6 and centralizing system can use the correction fixed system that patent disclosed of Chinese patent notification number as CN202047950U.
When piling work, hoisting crane 4 lifting drive hammer 7 realize major diameter single pile piling function.
As shown in Figure 1, the hull bow is provided with central control compartment and accommodation 8, and the living facilities that disposed can provide safeguard for crewman's life and rest.
As for example, other parameters of the erecting stage of present embodiment are given an example as follows: 30 meters of the maximum operation depth of waters, minimum design temperature-10 ℃.4 generator seies, rating horsepower 715KW, rated speed of rotation 1800r/min.1 of emergency dynamo, rating horsepower 250KW, rated speed of rotation 1800r/min.
Generally speaking, the erecting stage of present embodiment is with functions such as marine weight lifting, piling, installations.The weight lifting is divided into the floading condition lifting again and spud leg inserts the lifting of sea bed lifting locking state, and load-carrying ability is 800 tons of full circle swingings.
The wind-powered electricity generation installing area in the coastal waters, it will be driven piles on the basis, and transition phase is installed and several stages such as tower tube and fan blade installation play irreplaceable effect.Its operating process is summarized as follows:
1, towboat with erecting stage from female port holder put down spud leg to specifying the marine site, the ballast operation is carried out in the operation of beginning pitching pile subsequently, after the step through regulation, platform steadily stand on sea bed.
2,, make platform off sea the specified altitude assignment of climbing through the lifting catch gear 2 of independent research; Hoisting crane 4 breaks away from shelf, puts down suspension hook, and the foundation pile of lifting blower fan returns back to accurate seat in the plane on the carrier from the side after standing up, and vertically inserts sea bed.
3, through pile holding device 6, guarantee that pile body goes into the vertical precision of mud, lifting drive hammer 7 begins the piling operation, reaches the absolute altitude of regulation until pile body, and piling finishes.
Installation phase at subsequently transition phase needs flat-bed spud leg 3 that stable operating environment is provided, and the lifting catch gear 2 of jack up cooperates with the hoisting crane 4 of full circle swinging, realizes that transition phase is installed on the foundation pile accurately.
After finishing the installation of transition phase, the follow-up tower tube and the installation of blower fan cabin and blade, similar with the front, all be unable to do without from the stable rotary crane 4 that reaches variable-angle of the flat-bed that goes up and down, finally accomplish marine high-precision installation exercise.
Though the present invention discloses as above with preferred embodiment; Right its is not that any those skilled in the art are not breaking away from the spirit and scope of the present invention in order to qualification the present invention; When can doing a little modification and perfect, so protection scope of the present invention is when being as the criterion with what claims defined.
