The specific embodiment

Be elaborated below in conjunction with the specific embodiment of accompanying drawing to Floating Crane of the present utility model.

Referring to Fig. 1,2, Fig. 1 is that Floating Crane 100 of the present utility model grasps the scheme drawing that is played weight; Fig. 2 is the birds-eye view of Fig. 1.

Floating Crane 100 of the present utility model is made up of two major parts: hoisting crane 50 that is played a weight (present embodiment is for having installed the whole aerogenerator 200 of the powerplant module tower body of fan blade) and the anchoring device 60 that places hoisting crane 50 bottoms are installed.

Above-mentioned hoisting crane 50 is made up of three parts: put the hull 1 that is played weight (present embodiment is the above-mentioned whole aerogenerator of mentioning 200); By pivoting support 14 and hull 1 bonded assembly crane main body 12; On crane main body 12, have jacking system 11, crane arm 8 is housed on the jacking system 11, to realize the elevating function of crane arm 8.

On the crane arm 8 of lifting handgrip 9 is housed also, handgrip 9 is seated on the parallel motion track 13 on the crane arm 8, and be connected with 2 horizontal drive oil cylinders 10 of horizontal arrangement on crane arm, realize that handgrip 9 is along parallel motion track 13 translations on the crane arm 8, handgrip 9 is hinged with crane arm 8, can make handgrip 9 well contain the body of the tower of whole aerogenerator 200.

Handgrip 9 is special-purpose members, it and the size of various different wind power plant 200 shafts coupling, and therefore, handgrip 9 is except itself can adjust within the specific limits, and the specifications and models that also have various different sizes are done standby, to adapt to different job requirements.

The detailed structure of handgrip 9 is seen Fig. 3, Fig. 4, the constructional drawing the when constructional drawing when Fig. 3 opens for handgrip, Fig. 4 are the handgrip closure.Handgrip 9 is made of the centre of the palm 21 and claw 22 2 parts, in Fig. 3, Fig. 4, the centre of the palm 21 is a circular arc, its radius of curvature coincide with the circular arc of the whole aerogenerator 200 that will grasp (by playing weight) shaft, and claw 22 is connected with switching hydraulic ram 23, and claw 22 is hinged by hinge 24 with the centre of the palm 21, carry out closure and opening movement around hinge 24, its power is to open and close hydraulic ram 23 by claw to realize, above-mentionedly mentions, and the circular arc of claw 22 is with consistent by a weight circular arc.Opening and closing hydraulic ram 23 at claw 22 holds tightly under the powerful propelling thrust of oil cylinder, whole aerogenerator 200 will be contained by the centre of the palm 21 of handgrip 9 and claw 22 and hold with a firm grip, whole aerogenerator 200 is mentioned and put down by jacking system 11, utilize center steering bearing 4 and parallel motion track 13, can realize of the motion of whole aerogenerator 200, use so that contraposition is installed in the horizontal surface direction.

Above-mentioned crane main body 12 is positioned at the afterbody of hull 1, and the stability of hull 1 realizes by the following anchoring device that is made of several columns 61 that will illustrate 60 during work.On hull 1, be equipped with circuit orbit 5 around above-mentioned center steering bearing 4, crane main body 12 can be done gyroscopic movement around center steering bearing 4 on the circuit orbit on the hull 15, and jacking system 11 can be realized the up-and-down movement of crane arm 8.

2 horizontal drive oil cylinders 10 of horizontal arrangement can be realized the fore and aft motion (sway stroke L be 15m) of handgrip 9 on the parallel motion track 13 of crane arm 8 on the above-mentioned crane arm 8.

The below of crane arm 8 is provided with 2 auxiliary cylinders 7 in addition, this auxiliary cylinder 7 has 2 effects, effect is to prevent that the influence too high owing to center of gravity or strong wind of the body of the tower of whole aerogenerator 200 from tumbling, another effect also can with 10 collaborative works of horizontal drive oil cylinder, realize the vert adjustment of body of the tower in certain angle.

About above-mentioned jacking system 11 has 2, also can realize the motion of verting on a small quantity of body of the tower by the motion of these 2 jacking system 11 differing heights, be convenient to the adjustment of body of the tower attitude, the changing of the relative positions of 2 horizontal drive oil cylinders 10 arranging above by crane arm 8 also can realize the gyroscopic movement of body of the tower in addition, and the contraposition of being convenient to the bolt with flange hole is installed.Slipping mechanism 3 is installed on the deck of hull 1, the body of the tower level that is loaded in the whole aerogenerator 200 on the hull 1 is shifted to crane main body 12, be convenient to handgrip 9 and grasp.

24 is hinges of handgrip among the figure, and it is the oscillating axle of whole handgrip, and the combined action by auxiliary cylinder among Fig. 17 and horizontal drive oil cylinder 10 realizes the verting of body of the tower of whole aerogenerator 200.When whole extracting and installation, at first by the operating range of the slipping mechanism 3 on the deck of hull 1 with 200 whole shift-in crane main body 12 of whole aerogenerator, manipulating crane main body 12 is turned back to the position of whole aerogenerator 200, open claw 22, mobile handgrip 9 is near the body of the tower of whole aerogenerator 200, the claw that control claw 22 opens and closes opens and closes oil cylinder 23, make claw 22 tightly embrace the body of the tower of whole aerogenerator 200, after treating that whole handgrip 9 grip forces reach preset value, utilize jacking system 11, rotary crane main body 12, inclining rotary mechanisms etc. are seated to the body of the tower of whole aerogenerator 200 on the extra large foundation pile 80 down, tightly be screwed to connect bolt, and unclamp handgrip 9, withdraw from behind the handgrip 9 second whole aerogenerator 200 grasped in crane arm 8 revolutions.

Above-mentioned anchoring device 60 is to make 50 stabilizations of whole hoisting crane in hoisting crane 100 operation process on the water, to avoid the wave influence.

Anchoring device 60 can be about to the hull 1 of hoisting crane 50 certainly and be ejected the water surface, and the draft of hull 1 is 4-8m, and the S point among Fig. 1 is the sea level.

Anchoring device 60 constitutes by being no less than 3 columns 61, every root post 61 passes the hull 1 of hoisting crane 50, the position of passing hull 1 at column 61 has some groups of side wheels to assemble the guide piece that constitutes, the dipping and heaving of the column control of leading, every root post 61 is connected with the upright column elevator structure, with 61 liftings of realization column, thereby hull 1 is ejected the water surface, make hull 1 no longer be subjected to the influence of wave, to keep the stable of hull 1.Described upright column elevator structure is pinion and-rack or steel rope traction-type.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the purpose of this utility model, and be not with opposing qualification of the present utility model, as long as in essential scope of the present utility model, all will drop in the scope of claim of the present utility model variation, the modification of the above embodiment.
