Description

Fan integral installation rotating holding mechanism
Technical field
The present invention relates to the offshore engineering equipment technical field, relate in particular to a kind of offshore wind turbine integral installation rotating holding 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, then mechanical energy is converted into a kind of generation mode of electric energy.Substantially, develop completely due to the wind power plant of land, 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 vital step that blower fan (being wind power generating set) is installed.Blower fan is installed to be referred to assembling on the mounting base (normally butt flange) on the blower foundation in marine setting in advance.Generally need to install by the blower installation platform of offshore wind turbine installation exercise special use.
In general, mainly contain following two kinds of assembling modes: split type installation and integral type are installed.

As Fig. 4～shown in Figure 10, the upper end of suspension rod 69 is provided with the top universal hinging link 80 that is connected with the central annulus 68 of bearing beam 61.Top universal hinging link 80 is made of following part: the upper connecting base 89 that is connected with central annulus 68; The first intermediate connector 85; The bearing pin 82 that connects upper connecting base 89 and the first intermediate connector 85; Upper bar 90; The bearing pin 83 that connects the first 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, namely the distribution circle along upper connecting base 89 radially extends, and the axis of bearing pin 83 is at the axis quadrature of overlooking under the visual angle with bearing pin 82, and namely the distribution circle tangential direction on central annulus 68 is extended along upper connecting base 89.
The lower end of suspension rod 69 is provided with the bottom universal hinging link 81 that is connected with hanging basket 70.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 made of following part: the lower connecting base 91 that is connected with hanging basket 70; The second intermediate connector 88; The bearing pin 87 that connects lower connecting base 91 and the second intermediate connector 88; Lower pole 92; The bearing pin 93 that connects the second 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 ', namely the distribution circle along lower connecting base 91 radially extends, and the axis of bearing pin 93 is at the axis quadrature of overlooking under the visual angle with bearing pin 87, and namely the distribution circle tangential direction on hanging basket 70 is extended along lower connecting base 91.
As Fig. 7 and shown in Figure 10, the middle part of suspension rod 69 is provided with the flexible link 86 of reversing.The flexible link 86 of reversing is made of following part: the top has the end of larger bead, bar and the interconnecting piece 95 that upper bar 90 is spirally connected; The outer connector 96 of the through hole that profile is that cup-shaped, rim of a cup section and lower pole 92 are spirally connected, the bottom has interconnecting piece 95 bar section is passed; Be arranged on thrust baring 97 and elastic element (the dish spring can be also the 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 section of interconnecting piece 95 and outer connector 96 is free-running fit.According to this structure as can be known, the power of bearing when suspension rod 69 is during greater than the regulation pulling force, and elastic element 98 is further compressed, and it is large that gap delta becomes, and the length of suspension rod 69 increases; The power of bearing when suspension rod 69 is during less than the regulation pulling force, and the axial length of elastic element 98 is returned to the length corresponding with its power of bearing, and gap delta diminishes, and the length of suspension rod 69 reduces.In addition, due to the existence of thrust baring 95, even in the situation that upper bar 90 and lower pole 92 bear very large pulling force, also relative torsion very like a cork.
Below central annulus 68, suspension rod 69 and the hanging basket 70 of this structure carried out kinematics analysis.
Figure 11 means the schematic diagram of the lower connecting base on hanging basket 70 91 situation of change on distribution circle when hanging basket 70 only rotates.
Distribution circle diameter due to the upper connecting base 89 on the central annulus 68 of being fixed on 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, overlook under the visual angle, the O of circle ring center of central authorities and hanging basket center O ' coincidence, two distribution circles overlap, and also overlap as a bit at two Connection Blocks 89,91 up and down of overlooking same suspension rod under the visual angle.For ease of describing, as shown in figure 11, suppose that two Connection Blocks 89 up and down, 91 of suspension rod a are positioned on X-axis overlooking under the visual angle 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 central annulus 68, the lower end be fixed on lower connecting base 91 on 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 setting party always sees, because the axis of bearing pin 82 passes the center O of central annulus 68, namely the distribution circle along upper connecting base 89 radially extends, the axis of bearing pin 87 pass the center O of hanging basket 70 ', namely the distribution circle along lower connecting base 91 radially extends, and the axis quadrature 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), that the first intermediate connector 85 by top universal hinging link 80 is around bearing pin 82 rotations, rotate around bearing pin 87 (as shown in the Fig. 7 (b)) that realizes with the second intermediate connector 88 of bottom universal hinging link 81, and lower connecting base 91 is along the radially motion of (X-direction) of its distribution circle, to rotate around bearing pin 83 by the upper bar 90 of top universal hinging link 80, rotate around bearing pin 93 (as shown in the Fig. 7 (c)) that realizes with the lower pole 92 of bottom universal hinging link 81.
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 and bottom universal hinging link 81 can not relative torsions, so being thrust baring 97 in the flexible torsion link 86 that arranges by the middle part at suspension rod 69, this rotation realizes.
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 the left and right is each 1.5 °), again because the distribution circle diameter of upper connecting base 89 and lower connecting base 91 is very large, 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, around bearing pin 82 rotations by the first intermediate connector 85, realize around bearing pin 87 rotation with the second intermediate connector 88, lower connecting base 91 moves along X-direction, around bearing pin 83 rotations by upper bar 90, realize around bearing pin 93 rotation with lower pole 92, so, the first intermediate connector 85 is around bearing pin 82 and the second 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 cylinder 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 large, can make the first intermediate connector 85 very little around the angle of bearing pin 87 rotations around bearing pin 82 and the second intermediate connector 88, that is to say, can make upper bar 90 less around the angle of bearing pin 93 rotations around bearing pin 83 and lower pole 92.
like this, be actually will be larger to translatory distance the relevant bearing pin 82 of tangential motion (Y direction), 87 are arranged between the upper connecting base 89 and the first intermediate connector 85 of top universal hinging link 80, and between the lower connecting base 91 of bottom universal hinging link 81 and the second intermediate connector 88, the relevant bearing pin 83 of radial motion that will be less to translatory distance (X-direction), 93 are arranged between first intermediate connector 85 and upper bar 90 of top universal hinging link 80, and between second intermediate connector 88 and lower pole 92 of bottom universal hinging link 81, the torsion link 86 of stretching is arranged between upper bar 90 and lower pole 92.from another angle, the bearing pin 82 that exactly distribution circle along upper connecting base 89 of top universal hinging link 80 is radially extended is arranged between the upper connecting base 89 and the first intermediate connector 85 that is connected with central annulus 68, to be arranged between the first intermediate connector 85 and 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 is arranged between the lower connecting base 91 and the second intermediate connector 88 that is connected with hanging basket 70, to be arranged between the second intermediate connector 88 and lower pole 92 along the bearing pin 93 that the distribution circle tangential direction of lower connecting base 91 is extended, the torsion link 86 of stretching is arranged between upper bar 90 and lower pole 92.
can find out from Fig. 7 (c), if relative the first intermediate connector 85 of upper bar 90, and the larger words of angle of relative the second intermediate connector 88 deflections of lower pole 92, upper connecting base 89 and lower connecting base 91 will bear very large side direction moment of flexure, but due to the bearing pin 82 that top universal hinging link 80 is set as above and bearing pin 83, and the bearing pin 87 of bottom universal hinging link 81 and bearing pin 93, again due to lower connecting base 91 along distribution circle move radially very little apart from x, relative the first intermediate connector 85 of upper bar 90, and the angle of relative the second intermediate connector 88 deflections of lower pole 92 is just very little, so, when hanging basket 70 rotation, even suspension rod 69 bears very large pulling force, the suffered side direction moment of flexure of upper connecting base 89 and lower connecting base 91 also can be very little, be unlikely to damage upper connecting base 89 and lower connecting base 91.
because the distribution circle diameter of the distribution circle of upper connecting base 89 and lower connecting base 91 is identical, and two Connection Blocks 89 up and down of same suspension rod 69, 91 positions on distribution circle are also identical, so, if hanging basket 70 only relatively central annulus 68 rotates around center O ' (center O of central annulus 68) of hanging basket 70, other lower connecting base 91 on other suspension rod 69 and hanging basket 70 is done with above-mentioned and is analyzed suspension rod 69 action identical with lower connecting base 91, hanging basket 70 can relatively central 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 means at hanging basket 70 not only translation but also the schematic diagram of the situation of change of lower connecting base 91 on distribution circle on 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 the suspension rod b on reversing sense and suspension rod c.Because suspension rod a is on 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, then rotated angle γ to anticlockwise direction, 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, point 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 central annulus 68 is in the same plane, the lower connecting base 91 that is fixed on 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.Although 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 torsion are all very little, so the length of suspension rod 69 differs very little, therefore, be provided with the flexible link 86 of reversing on suspension rod 69.As shown in figure 10, the power that the flexible elastic element 98 that reverses in link 86 bears at suspension rod 69 is during greater than the regulation pulling force, elastic element 98 is further compressed, it is large that gap delta becomes, the length of suspension rod 69 increases, and the power of bearing when suspension rod 69 is during less than the regulation pulling force, and the length of elastic element 98 is returned to the length corresponding with its power of bearing, gap delta diminishes, and the length of suspension rod 69 reduces.The suffered pulling force of each suspension rod 69 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, is integrally formed with bearing beam 61.As shown in Figure 4 and Figure 5, be provided with torsion device (torsion 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 subject 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 transverse fine-adjusting device 52 and vertical micromatic setting 53 consist of the translation device of fan integral installation rotating holding mechanisms of the present invention.If drive transverse fine-adjusting device 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 motions relatively.Should be noted in the discussion above that this rotating holding lifts the level attitude fine setting that the horizontally moving functions of mechanism 6 only is used for blower fan tower barrel 31, the adjustment of the level attitude of large distance is to be completed by the horizontally moving device 26 of portal frame 16.
Below version and the principle of work of enclasp device 7 described.
Figure 13 means the structural representation of the mode of operation of enclasp device 7.
As Fig. 4 and shown in Figure 13, enclasp device 7 is controlled oil cylinder 10 by strut 8, pressing plate 9 and pressing plate and is consisted of.One end of strut 8 is hinged on 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.Stretch out if pressing plate is controlled the piston rod of oil cylinder 10, strut 8 is around the bearing pin rotation hinged with hanging basket 70, and the other end band dynamic pressure plate 9 of strut 8 leaves blower fan tower barrel 31.
Shrink if pressing plate is controlled the piston rod of oil cylinder 10, strut 8 is around the bearing pin rotation hinged with hanging basket 70, and the other end band dynamic pressure plate 9 of strut 8 is pressed against the seal face of the friction material layer that is pasted with large friction coefficient of pressing plate 9 on the surface of tower cylinder 31.Here, the seal face of pressing plate 9 is called friction face with the face that tower cylinder 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 cylinder 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 cylinder 31 is less than the friction angle on the seal face of pressing plate 9 and tower cylinder 31 surfaces
Figure GDA00001790690700151
That is, if the friction coefficient on the seal face of pressing plate 9 and tower cylinder 31 surfaces is μ,
Figure GDA00001790690700152
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 produces on friction face thus (vertically) is μ Fcos α, and vertical component of strut 8 pushing pressing plates 9 is Fsin α, if make μ Fcos α＞Fsin α, tg α＜μ, namely
Figure GDA00001790690700153
That is to say, if the force direction of strut 8 is at the friction angle on the seal face of pressing plate 9 and tower cylinder 31 surfaces
Figure GDA00001790690700154
Scope within, self-locking alleged in theoretical mechanics and theory of machines (self-lock) phenomenon just appears, friction force on its friction face is forever greater than the component that makes progress of strut 8, and in fact a plurality of strut 8 shareds make progress just equal with joint efforts the gravity of blower fan 2 and tower cylinder 31.In other words, this version is when hanging basket 70 upwards promotes, due to the force direction of strut 8 friction angle on the seal face of pressing plate 9 and tower cylinder 31 surfaces
Figure GDA00001790690700155
Scope within, locking phenomenon appears, so pressing plate 9 can be along tower cylinder 31 surface slidings, but the strut 8 of enclasp device 7 is pressed against pressing plate 9 on tower cylinder 31 more forcefully, tower cylinder 31 is more heavily embraced tightlyer.
For the paint face and the larger friction coefficient of acquisition that do not damage tower cylinder 31, friction material layer pressing plate 9, large friction coefficient that contact with tower cylinder 31 is selected slightly softer rubber usually, also can paste one deck leather again or imitate leather and weave cotton cloth outside rubber layer.
In addition, owing to (only showing an enclasp device 7 in Figure 13 along a plurality of enclasp devices 7 of circumferentially being evenly arranged of tower cylinder 31 on hanging basket 70.), so the radial thrust of a plurality of strut 8 pushing pressing plates 9 all acts on tower cylinder 31 and cancels out each other, and the component that makes progress of strut 8 pushing pressing plates 9 finally acts on tower cylinder 31 with the form of friction force by pressing plate 9, balances each other with the gravity of blower fan 2 and tower cylinder 31.
Because enclasp device 7 is arranged on 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, blower fan tower barrel 31 also rotates or parallel motion thereupon.Therefore, by driven relative bearing beams 61 rotation or the parallel motions of hanging basket by torsion device 51, transverse fine-adjusting device 52 or vertical micromatic setting 53, can make relative bearing beam 61 rotation or the parallel motions of blower fan tower barrel 31.
