Technical field
The present invention relates to the offshore engineering equipment technical field, relate in particular to a kind of offshore wind generating group integral installation rotation and embrace act mechanism.
Background technology
Wind energy belongs to clean energy resource.Wind-power electricity generation is exactly that the kinetic energy of keeping watch is transformed into mechanical energy, mechanical energy is converted into a kind of generation mode of electric energy again.Because the wind power plant of land is developed substantially and finished, and marine wind resource is very abundant, and therefore, increasing wind power plant construction at sea.Carry out the construction of wind power plant at sea, it is crucial step that blower fan (being wind power generating set) is installed.The installation blower fan is meant blower fan is installed in advance on the mounting base on the blower foundation of marine setting (normally butt flange).Generally need to install by the blower fan erecting stage of offshore wind turbine installation exercise special use.
In general, mainly contain following two kinds of blower fan mounting meanss: split type installation and integral type are installed.
Split type installation is the wind power plant that with the carrying ship each parts loose mail of blower fan is transported to the predetermined maritime area earlier, utilize the blower fan erecting stage parts such as tower tube, cabin, wheel hub and blade of lifting fan successively then, thus blower fan is installed on the blower fan mounting base.

As Fig. 4~shown in Figure 10, the upper end of suspension rod 69 is provided with the central annulus 68 bonded assembly top universal hinging links 80 with bearing beam 61.Top universal hinging link 80 is by constituting with the lower part: with central annulus 68 bonded assembly upper connecting bases 89; Intermediate connector 85; The bearing pin 82 that connects upper connecting base 89 and intermediate connector 85; Upper bar 90; The bearing pin 83 that connects intermediate connector 85 and upper bar 90.As shown in Figure 4, the axis of bearing pin 82 passes the center O of central annulus 68, promptly the distribution circle along upper connecting base 89 radially extends, and the axis of bearing pin 83 in birds-eye view with the orthogonal axe of bearing pin 82, promptly extend along the distribution circle tangential direction of upper connecting base 89 on central annulus 68.
The lower end of suspension rod 69 is provided with and hanging basket 70 bonded assembly bottom universal hinging links 81.The structure of bottom universal hinging link 81 is identical with the structure of top universal hinging link 80.As Fig. 4, Fig. 7 and shown in Figure 9, bottom universal hinging link 81 is by constituting with the lower part: with hanging basket 70 bonded assembly lower connecting bases 91; Intermediate connector 88; The bearing pin 87 that connects lower connecting base 91 and intermediate connector 88; Lower pole 92; The bearing pin 93 that connects intermediate connector 88 and lower pole 92.As shown in Figure 4, the axis of bearing pin 87 pass the center O of hanging basket 70 ', promptly the distribution circle along lower connecting base 91 radially extends, and the axis of bearing pin 93 in birds-eye view with the orthogonal axe of bearing pin 87, promptly extend along the distribution circle tangential direction of lower connecting base 91 on hanging basket 70.
As Fig. 7 and shown in Figure 10, the middle part of suspension rod 69 is provided with the flexible link 86 of reversing.Stretch and reverse link 86 by constituting with the lower part: the top has the end of bigger bead, bar and the interconnecting piece 95 that upper bar 90 is spirally connected; Profile is the outer connector 96 of the through hole that passes of cup-shaped, rim of a cup portion and lower pole 92 are spirally connected, the bottom has interconnecting piece 95 bar portion; Be installed in thrust baring 97 and elastic element (the dish spring also can be elastic elements such as coil spring or rubber column) 98 between the bottom interior surface of the inside top of interconnecting piece 95 and outer connector 96.As shown in figure 10, when suspension rod 69 bears the pulling force of regulation, leave gap delta between the bottom outer surface of the end of upper bar 90 and outer connector 96 and between the end of the top outer of interconnecting piece 95 and lower pole 92.In addition, the bottom through-hole of the bar portion of interconnecting piece 95 and outer connector 96 is a free-running fit.According to this structure as can be known, the power of being born when suspension rod 69 is during greater than the regulation pulling force, and elastic element 98 further is compressed, and it is big that gap delta becomes, and the length of suspension rod 69 increases; The power of being born when suspension rod 69 is during less than the regulation pulling force, and the axial length of elastic element 98 is returned to and the corresponding length of its power of being born, and gap delta diminishes, and the length of suspension rod 69 reduces.In addition, because the existence of thrust baring 95 even bear under the situation of very big pulling force in upper bar 90 and lower pole 92, also can be reversed like a cork relatively very much.
Below central annulus 68, suspension rod 69 and the hanging basket 70 of this structure carried out kinematics analysis.
Figure 11 is the scheme drawing of lower connecting base 91 situation of change on distribution circle on the hanging basket 70 when being illustrated in hanging basket 70 and only rotating.
Because the distribution circle diameter that is fixed on the upper connecting base 89 on the central annulus 68 of suspension rod 69, identical and phase place is identical with the distribution circle diameter of lower connecting base 91 on being fixed on hanging basket 70, so, in birds-eye view, the O of circle ring center of central authorities and hanging basket center O ' coincidence, two distribution circles overlap, and two Connection Blocks 89,91 up and down of same suspension rod also overlap to a bit in birds-eye view.For ease of describing, as shown in figure 11, suppose that two Connection Blocks 89,91 up and down of suspension rod a are positioned on the X-axis in the birds-eye view of distribution circle.
As shown in figure 11, if hanging basket 70 is around its center O ' rotation, to anticlockwise direction anglec of rotation β, suspension rod a upper end be fixed on not motion of upper connecting base 89 on the central annulus 68, the lower end be fixed on lower connecting base 91 on the hanging basket 70 from the position 1 move to position 1 '.This is actually lower connecting base 91 and has moved the distance of y along the tangential direction (Y direction) of its distribution circle, along its distribution circle radially (X-direction) moved the distance of x.
Each bearing pin 82 from top universal hinging link 80 and bottom universal hinging link 81,83,87,93 direction is set, because the axis of bearing pin 82 passes the center O of central annulus 68, promptly the distribution circle along upper connecting base 89 radially extends, the axis of bearing pin 87 pass the center O of hanging basket 70 ', promptly the distribution circle along lower connecting base 91 radially extends, and the orthogonal axe of the axis of bearing pin 83 and bearing pin 93 and bearing pin 82 and bearing pin 87, so, lower connecting base 91 is along the motion of its distribution circle tangential direction (Y direction), be that intermediate connector 85 by top universal hinging link 80 is around bearing pin 82 rotations, rotate (shown in the Fig. 7 (b)) that realizes with the intermediate connector 88 of bottom universal hinging link 81 around bearing pin 87, and lower connecting base 91 is to rotate around bearing pin 83 by the upper bar 90 of top universal hinging link 80 along the radially motion of (X-direction) of its distribution circle, rotate (shown in the Fig. 7 (c)) that realizes with the lower pole 92 of bottom universal hinging link 81 around bearing pin 93.
In addition, as can be seen from Figure 11, at lower connecting base 91 during around the center O of hanging basket 70 ' to anticlockwise direction revolution angle beta, lower connecting base 91 also to the anticlockwise direction rotation angle beta.Because top universal hinging link 80 can not be reversed relatively with bottom universal hinging link 81, so this rotation is to realize by the flexible thrust baring 97 that reverses in the link 86 that the middle part at suspension rod 69 is provided with.
In addition, generally, the bolt hole of blower fan tower barrel butt flange a lot (for example 120), bolt hole centering only need be rotated very little angle (for example each 1.5 °), again because the distribution circle diameter of upper connecting base 89 and lower connecting base 91 is very big, so, in fact lower connecting base 91 along the miles of relative movement y of Y direction out and away greater than move along X-direction apart from x, and because lower connecting base 91 moving along Y direction, be around bearing pin 82 rotations by intermediate connector 85, realize around bearing pin 87 rotation with intermediate connector 88, lower connecting base 91 moves along X-direction, be around bearing pin 83 rotations by upper bar 90, realize around bearing pin 93 rotation with lower pole 92, so, intermediate connector 85 is around bearing pin 82 and intermediate connector 88 angle around bearing pin 87 rotations, out and away greater than upper bar 90 around bearing pin 83 and lower pole 92 angle around bearing pin 93 rotations.That is to say, in the angle shown in Fig. 7 (b) out and away greater than in the angle shown in Fig. 7 (c).
In addition, if the number of the bolt hole of the distribution circle diameter of lower connecting base 91 and tower tube butt flange is fixed, the miles of relative movement x of lower connecting base 91 and y are just fixed, if make the length of suspension rod 69 enough big, then can make intermediate connector 85 very little around the angle of bearing pin 87 rotations around bearing pin 82 and intermediate connector 88, that is to say, can make upper bar 90 littler around the angle of bearing pin 93 rotations around bearing pin 83 and lower pole 92.
Like this, be actually will be bigger with translatory distance the relevant bearing pin 82 of tangential motion (Y direction), 87 are arranged between the upper connecting base 89 and intermediate connector 85 of top universal hinging link 80, and between the lower connecting base 91 and intermediate connector 88 of bottom universal hinging link 81, the relevant bearing pin 83 of radial motion that will be less (X-direction) with translatory distance, 93 are arranged between the intermediate connector 85 and upper bar 90 of top universal hinging link 80, and between the intermediate connector 88 and lower pole 92 of bottom universal hinging link 81, will stretch and reverse link 86 and be arranged between upper bar 90 and the lower pole 92.From another angle, exactly the bearing pin 82 that the distribution circle along upper connecting base 89 of top universal hinging link 80 is radially extended be arranged on and central annulus 68 bonded assembly upper connecting bases 89 and intermediate connector 85 between, to be arranged between intermediate connector 85 and the upper bar 90 along the bearing pin 83 that the distribution circle tangential direction of upper connecting base 89 is extended, the bearing pin 87 that the distribution circle along lower connecting base 91 of bottom universal hinging link 81 is radially extended be arranged on and hanging basket 70 bonded assembly lower connecting bases 91 and intermediate connector 88 between, to be arranged between intermediate connector 88 and the lower pole 92 along the bearing pin 93 that the distribution circle tangential direction of lower connecting base 91 is extended, will stretch and reverse link 86 and be arranged between upper bar 90 and the lower pole 92.
From Fig. 7 (c) as can be seen, if upper bar 90 relative intermediate connectors 85, and the bigger words of angle of lower pole 92 relative intermediate connector 88 deflections, upper connecting base 89 and lower connecting base 91 will bear very big side direction moment of flexure, but because the bearing pin 82 and the bearing pin 83 of top universal hinging link 80 are set as above, and the bearing pin 87 of bottom universal hinging link 81 and bearing pin 93, again since lower connecting base 91 along distribution circle move radially very little apart from x, upper bar 90 relative intermediate connectors 85, and the angle of lower pole 92 relative intermediate connector 88 deflections is just very little, so, when hanging basket 70 rotations, even suspension rod 69 bears very big pulling force, upper connecting base 89 and lower connecting base 91 suffered side direction moments of flexure also can be very little, are unlikely to damage upper connecting base 89 and lower connecting base 91.
Because the distribution circle of upper connecting base 89 is identical with the distribution circle diameter of lower connecting base 91, and two Connection Blocks 89 up and down of same suspension rod 69,91 positions on distribution circle are also identical, so, if the only central relatively annulus 68 of hanging basket 70 is around center O ' (center O of the central annulus 68) rotation of hanging basket 70, other suspension rod 69 and other lower connecting base 91 on the hanging basket 70 are done with above-mentioned and are analyzed the identical action of suspension rod 69 and lower connecting base 91, hanging basket 70 can central relatively annulus 68, be that relative bearing beam 61 rotates to an angle reposefully, and be unlikely to damage upper connecting base 89 and lower connecting base 91.
Figure 12 is illustrated in the hanging basket 70 not only translation but also the scheme drawing of the situation of change of lower connecting base 91 on distribution circle on the hanging basket 70 when rotating.
As shown in figure 12, suppose that hanging basket 70 has moved distance L to the reversing sense of X-axis, and then rotated angle γ to anticlockwise direction.Below to analyzing at the suspension rod a on the positive dirction of X-axis with in the motion conditions of the positive dirction of Y-axis and suspension rod b on the reversing sense and suspension rod c.Because suspension rod a is on the X-axis, and suspension rod b and suspension rod c are on the positive dirction and reversing sense of Y-axis, if hanging basket 70 has moved distance L to the reversing sense of X-axis, rotated angle γ to anticlockwise direction then, then not motion of the upper connecting base on central annulus 68 89, and the lower connecting base 91 on hanging basket 70 has different path of motion.The lower connecting base 91 of suspension rod a 1 moved to a little 1 from putting ', the lower connecting base 91 of suspension rod b 2 moved to a little 2 from putting ', the lower connecting base 91 of suspension rod c 3 moved to a little 3 from putting '.As can be known from Fig. 12,1 to point 1 ' distance, point 2 to point 2 ' distance and put 3 to point 3 ' distance and unequal.Because the upper connecting base 89 that is fixed on the central annulus 68 is in the same plane, the lower connecting base 91 that is fixed on the hanging basket 70 is also in the same plane, thus this moment suspension rod a, suspension rod b and the space length of suspension rod c be unequal.Though at hanging basket 70 not only parallel motion but also when reversing, the length requirement of each suspension rod 69 is different, because of suspension rod 69 very long, and the distance of parallel motion and the angle of reversing are all very little, so the length of suspension rod 69 differs very little, therefore, on suspension rod 69, be provided with the flexible link 86 of reversing.As shown in figure 10, the power that the flexible elastic element 98 that reverses in the link 86 bears at suspension rod 69 is during greater than the regulation pulling force, elastic element 98 further is compressed, it is big that gap delta becomes, the length of suspension rod 69 increases, and the power of being born when suspension rod 69 is during less than the regulation pulling force, and the length of elastic element 98 is returned to and the corresponding length of its power of being born, gap delta diminishes, and the length of suspension rod 69 reduces.Each suspension rod 69 suffered pulling force is tending towards evenly, and the pressurized that the tension that being unlikely to suspension rod 69 has has damages suspension rod 69 and hanging basket 70.
In addition, as shown in Figure 5, the below in the closed side of central annulus 68 (bearing beam 61) is provided with link span 50, constitutes one with bearing beam 61.As shown in Figure 4 and Figure 5, be provided with torsion device (reversing oil cylinder) 51 along the tangential direction of hanging basket 70, an end of torsion device 51 is hinged with ball pivot and hanging basket 70, and the other end and link span 50 are hinged, and make it be roughly horizontal positioned.If drive torsion device 51, hanging basket 70 is subjected to the power of tangential direction, and hanging basket 70 bearing beam 61 (central annulus 68) relatively reverses.In addition, between link span 50 and hanging basket 70, hinged with ball pivot and hanging basket 70 along an end of the horizontal fine setting oil cylinder 52 of radially being provided with of hanging basket 70 and vertical fine setting oil cylinder 53, two oil cylinders, the other end and link span 50 are hinged, make it be roughly horizontal positioned.This horizontal micromatic setting 52 and vertical micromatic setting 53 constitute blower fan integral installation rotation of the present invention and embrace a translation device of lifting mechanism.If drive horizontal micromatic setting 52 or vertical micromatic setting 53, hanging basket 70 bears the thrust of forward, and hanging basket 70 is bearing beam 61 (central annulus 68) parallel motion relatively.Should be noted in the discussion above that the horizontally moving functions of this rotation armful act mechanism 6 only is used for the level attitude fine setting of blower fan tower barrel 31, the adjustment of the level attitude of big distance is to be finished by the horizontally moving device 26 of portal frame 16.
Below the version and the principle of work of enclasp device 7 described.
Figure 13 is the structural representation of the mode of operation of expression enclasp device 7.
As Fig. 4 and shown in Figure 13, enclasp device 7 is made of strut 8, pressing plate 9 and pressing plate control oil cylinder 10.One end of strut 8 is hinged on the hanging basket 70, and the other end and pressing plate 9 are hinged, and an end of pressing plate control oil cylinder 10 and the inside lower end of hanging basket 70 are hinged, and close pressing plate 9 one sides of the other end and strut 8 are hinged.If the piston rod of pressing plate control oil cylinder 10 stretches out, then strut 8 is around rotating with hanging basket 70 pivotally attached bearing pins, and the other end of strut 8 drives pressing plate 9 and leaves blower fan tower barrel 31.
If the piston rod of pressing plate control oil cylinder 10 shrinks, then strut 8 around with the rotation of hanging basket 70 pivotally attached bearing pins, the other end of strut 8 drives pressing plate 9, and the seal face of the friction material layer that is pasted with big friction coefficient of pressing plate 9 is pressed against on the surface of tower tube 31.Here, the seal face of pressing plate 9 is called friction face with the face that tower tube 31 contacts.As shown in figure 13, the direction of strut 8 its application force when stressed is the line direction of two hinge-points, that is to say that strut 8 is two power bars.And be designed to when pressing plate 9 is pressed against on the surface of tower tube 31, the angle α of the normal direction of the friction face of the force direction of strut 8 and pressing plate 9 and tower tube 31 is less than the seal face of pressing plate 9 and the friction angle on tower tube 31 surfaces That is, if the friction coefficient on the seal face of pressing plate 9 and tower tube 31 surfaces is μ, then
According to theoretical mechanics as can be known, the thrust of supposing strut 8 is F, the conicity force of strut 8 pushing pressing plates 9 is Fcos α, the friction force that is produced on friction face (vertically) is μ Fcos α thus, and vertical component of strut 8 pushing pressing plates 9 is Fsin α, if will make μ Fcos α>Fsin α, tg α<μ then, promptly That is to say, if the force direction of strut 8 is at the seal face of pressing plate 9 and the friction angle on tower tube 31 surfaces Scope within, self-locking alleged in theoretical mechanics and the theory of machines (self-lock) phenomenon then just appears, friction force on its friction face is forever greater than the component that makes progress of strut 8, and the gravity that just equals blower fan 2 and tower tube 31 with joint efforts that makes progress that in fact a plurality of strut 8 is born jointly.In other words, this version is when hanging basket 70 upwards promotes, because the force direction of strut 8 is at the seal face of pressing plate 9 and the friction angle on tower tube 31 surfaces Scope within, locking phenomenon appears, so pressing plate 9 can not slide along tower tube 31 surface, but the strut 8 of enclasp device 7 is pressed against pressing plate 9 on the tower tube 31 more forcefully, tower tube 31 is more heavily embraced tightly more.
For the paint face that do not damage tower tube 31 and obtain bigger friction coefficient, the friction material layer of big friction coefficient pressing plate 9, that contact with tower tube 31 is selected softer slightly rubber for use usually, also can paste one deck leather again or imitate to remove from office and weave cotton cloth outside rubber layer.
In addition, owing to arrange that at the circumferentially even of hanging basket 70 upper edge tower tubes 31 a plurality of enclasp devices 7 (only show an enclasp device 7 in Figure 13.), so the radial thrust of a plurality of strut 8 pushing pressing plates 9 all acts on the tower tube 31 and cancels out each other, and the component that makes progress of strut 8 pushing pressing plates 9 finally acts on the tower tube 31 with the forms of friction force by pressing plate 9, balances each other with the gravity of blower fan 2 and tower tube 31.
Because enclasp device 7 is arranged on the hanging basket 70, when enclasp device 7 was held blower fan tower barrel 31 tightly, hanging basket 70 and blower fan tower barrel 31 became the integral body of a rigidity, so, hanging basket 70 rotation or parallel motions, then blower fan tower barrel 31 also rotates or parallel motion thereupon.Therefore, by drive relative bearing beam 61 rotation or the parallel motions of hanging baskets by torsion device 51, horizontal micromatic setting 52 or vertical micromatic setting 53, can make blower fan tower barrel 31 relative bearing beams 61 rotation or parallel motions.
