In order to increase the rigidity of upper vibration damper 6, increase the ability of its anti-load, preferably, wing plate 64 can be 2-6 layer.It should be noted that, whether no matter connect between symmetrical wing plate 64, the wing plate 64 along the transverse center symmetry of upper vibration damper 6 is same layer.
In order to increase the lateral stiffness of upper vibration damper 6, can make its absorptive amplitude and vibration acceleration better, absorbing vibration ability better, the angle that the line stretcher of the tilting section of symmetrical wing plate 64 forms is between 45-170 degree.Preferably, angle is 135 degree.
In order to actual user demand, upper vibration damper 6 also can arrange vertical adjustment hole 68, as shown in Figure 9.The rigidity of upper vibration damper 6 can be regulated by the size of the effective diameter of adjustment hole 68 and sectional shape, thus meet the different demands to the rigidity property of upper vibration damper 6 in actual using process.The sectional shape of adjustment hole 68 can be circular, square, polygonal, ellipse or quincunx etc. in one.
According to an embodiment, in order to increase the surface elasticity of upper vibration damper 6 and improve its wear resistance, one deck wearing course 67 can also be set on the outer surface of upper vibration damper 6, as seen in figs. 8-10.This wearing course 67 can be rubber layer, and and between the first cover plate 61, second cover plate 62 and dividing plate 65 integral type sulfuration form.
It should be noted that, in basis, vibration damper 6 is not limited to be applicable to wind power generating set, can also be used for other industry and field, such as truck, railway train, the other fields such as aircraft.
In support device 100 using process, first utilize the second link 12 by pre-assembled to upper beam 9, bottom end rail 3, column 5 and supporting element 2 for supporting base 50, to facilitate carrying.When the toggle 18 with gear-box is installed, first unscrew nut 13 to the certain position of control second link 12.Then supporting base 50 integral hoisting is enclosed within the toggle 18 of gear-box.In hoisting process, because being unscrewed by nut 13, and column 5 becomes an entirety with upper beam 9 by the first link 10, then gap appears in column 5 and bottom end rail 3.Thus, supporting base 50 can be set on toggle 18 easily.And then nut 13 is tightened the gap between column 5 and bottom end rail 3 is eliminated.Now, upper vibration damper 6 and lower vibration damper 6 ' are all in precompression installment state.Measure the distance between supporting element 2 and frame 20 again.Then, the 3rd link 15 is screwed in frame 20 through supporting base 50, but does not tighten the nut 16 be arranged on the 3rd link 15.Then top is stretched part (such as jack 19) and is placed in supporting and space 52 place, whole supporting base 50 is supported, this at present vibration damper 6 ' be extruded.According to the distance between the supporting element 2 measured above and frame 20, below supporting element 2, plug adds the pad of a series of different-thickness specification, realizes gap value and compensates.Then jack 19 is removed, fastening nut 16, complete the installation of support device 100 and the centering of gear-box.
It should be noted that, above-mentioned installation method is limited to the situation having supporting element 2.And when there is no supporting element 2, the form of lifting can be adopted to carry out lifting operation to supporting base 50.Further, when in order to carry out centering operation, need to measure the distance between the lower surface of bottom end rail 3 and frame 20.And this structure and operating method those skilled in the art will envision that, omit detailed description at this.
When upper vibration damper 6 needs to change, first come loose nut 16 and nut 13 to certain position, but not exclusively remove.Then in supporting and space 52, jack 19 is placed, by supporting base 50 jack-up.This at present vibration damper 6 ' be squeezed, vibration damper 6 is separated with upper beam 9, just can carry out the replacing of upper vibration damper 6.If need to change lower vibration damper 6 ', first come loose nut 16 and nut 13 to certain position, but not exclusively remove.Jack 19 is placed in supporting and space 52, and by supporting base 50 and supporting element 2 jack-up.Then the pad of a series of different-thickness specification is removed.Again jack 19 unloaded and take away.At this moment whole supporting base 50 sinks under gravity.And upper beam 9, column 5 and upper vibration damper 6 are tangled by the toggle 18 of gear-box, and bottom end rail 3, lower vibration damper 6 ' and supporting element 2 continue to sink.This at present vibration damper 6 ' separate with the toggle 18 of gear-box, and there is gap between column 5 and bottom end rail 3, thus just replaceable lower vibration damper 6 '.
After treating that vibration damper 6 and/or lower vibration damper 6 ' are changed, nut 13 is tightened, at this moment the gap between column 5 and bottom end rail 3 is eliminated, and upper vibration damper 6 and/or lower vibration damper 6 ' are all in precompression installment state, at this moment measures the gap between supporting element 2 and frame 20.After measurement, then it is interior by supporting element 2 jack-up to be placed in supporting and space 52 with jack 19, adds the pad 1 of a series of different-thickness specification according to the distance plug between the supporting element 2 just now measured and frame 20.Finally nut 16 is tightened, support device 100 is stably fixed in frame 20.
In like manner, above-mentioned maintaining method is limited to the situation having supporting element 2.And when there is no supporting element 2, the form of lifting can be adopted to carry out lifting operation to supporting base 50.And this structure and operating method those skilled in the art will envision that, omit detailed description at this.
Thus, can realize it being installed to rapidly on the toggle 18 of gear-box according to support device 100 of the present utility model, and centering operation can be carried out easily.Further, this support device 100 is conducive to realizing changing vibration damper rapidly.
In the application, term " vertically " is consistent with direction from top to bottom in Fig. 1, and term " transverse direction " refers to the direction vertical with " vertically ", consistent with direction from left to right or from right to left in FIG.
The foregoing is only preferred implementation of the present utility model; but the utility model protection domain is not limited thereto; any those skilled in the art is in technical scope disclosed in the utility model; can easily carry out changing or changing, and this change or change all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
