Abstract
The utility model discloses a generator supporting device of a wind power generating unit, and particularly relates to a generator supporting structure of a large-sized wind power generating unit. The supporting structure is characterized in that a frame (4) is welded with a main beam (1), a flat plate (2) and a 'Z'-shaped plate (5) are respectively welded to two sides of the main beam (1), the flat plate (2) is connected with a main framework (6) via bolts which are arranged horizontally, the 'Z'-shaped plate (5) is connected with the main framework (6) via bolts which are arranged vertically, and a generator rear support (3) is connected to the frame (4). The generator supporting structure resolves the problem that running stability is affected by increased vibration of generators, achieves required generator supporting strength, lightens the whole unit, reduces affection of vibration of the generators onto the unit body, and balances single-side torque caused by unidirectional rotation of the generators.
Description
Technical field
The utility model relates to a kind of generator of wind generating set support device, especially relates to a kind of large-scale generator of wind generating set supporting structure.
Background technique
Along with the continuous development of wind power technology, the power of wind-driven generator constantly increases, and the vibration of blower fan is also increasing.As the support of supporting one of vibration main source generator higher requirement will be proposed so.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of generator of wind generating set supporting structure, purpose be for solve the problem of the increasing operation stability that causes of generator vibration, generator supported the intensity, the weight that reduces complete machine that reach required, reduce the generator vibration to the influence of body, balance because the generator one-sided moment that causes of one-way rotation always.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The generator of wind generating set supporting structure, framework and Main Girder Welding are together, dull and stereotyped and " Z " shape plate is welded on the both sides of girder respectively, dull and stereotyped bolt with horizontal positioned is connected with mainframe, " Z " shape plate is connected with mainframe with the bolt of vertically placing, supporting base behind the connection generator on the framework.
Advantage of the present utility model and effect are as follows:
The utility model adopts said structure, has not only guaranteed the intensity that connects but also can reduce the influence of engine luggine to complete machine.Because bolt has flexibility for coupling, and coupling should be a rigidity.Because the plastic deformation amount is big, endergonic effect is strong, lowers the stress amplitude of varying stress when helping bearing cyclic loading, improves fatigue strength, also helps the effect of withstanding shocks.Connected member is overall work flexibly, and anti-fatigue ability is strong, is adapted to bear the structure of dynamic load and needs to guarantee to connect the little structure of distortion.For the unidirectional torque of balance owing to the generation of generator one-way rotation, the utility model adopts bolt pretightening to carry out balance, can significantly reduce the instability that main frame is caused in addition; Generator is supported reach required intensity, reduce complete machine weight, reduce the generator vibration to the influence of body, balance because the generator one-sided moment that causes of one-way rotation always.
Description of drawings
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is the structural representation of Fig. 1 middle plateform.
Fig. 3 is the structural representation of " Z " shape plate among Fig. 1.
Among the figure, 1, girder; 2, flat board; 3, supporting base behind the generator; 4, framework; 5, " Z " shape plate; 6 mainframes.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, but protection domain of the present utility model is not limit by embodiment.
As Figure 1-3, the utility model comprises girder 1, framework 4 welds together with girder 1, flat board 2 and " Z " shape plate 5 are welded on the both sides of girder 1 respectively, and the high-strength bolt that the high-strength bolt of its middle plateform 2 usefulness horizontal positioned is connected with mainframe 6, " Z " shape plate 5 usefulness are vertically placed is connected with mainframe 6.Supporting base 3 behind the connection generator on the framework 4.
Above-mentioned framework 4 is to be welded by angle steel, and girder 1 and " Z " shape plate 5 are to be formed by the steel plate bending.Mainframe 6 angle steel, flat board and " Z " shape plate all are welded on the girder 1, and the back supporting base of generator is also on girder.So girder is the important structure that generator supports.On dull and stereotyped and " Z " shape plate, there are four high-strength bolts to link to each other respectively, with the join strength of assurance generator support with mainframe.
Working principle of the present utility model: the utility model is that horizontal pretightening force that the high-strength bolt by horizontal positioned applies under certain torque coefficient supports generator with mainframe and links together with the unidirectional torque of balancing generator.By the high-strength bolt of vertically placing in addition mainframe and generator are supported on the gravity that links together balancing generator under the situation that applies pretightening force again.Can improve the intensity of structure so greatly, prolong the life-span of using.
Claims (1)
1. generator of wind generating set supporting structure, be characterised in that structure is as follows: framework (4) welds together with girder (1), dull and stereotyped (2) and " Z " shape plates (5) are welded on the both sides of girder (1) respectively, dull and stereotyped (2) are connected with mainframe (6) with the bolt of horizontal positioned, " Z " shape plate (5) is connected with mainframe (6) with the bolt of vertically placing, and framework (4) is supporting base (3) behind the connection generator upward.
