Description
Technical Field
The utility model belongs to the technical field of centering devices, and particularly relates to an integral centering device of a wind driven generator.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
At present, wind generating set manufacturers and fans at home and abroad have more types, and a plurality of generators of different types exist in the same electric field, and take the east-in-the-world wind power plant accepted by our company as an example, there are Xiangtan, yongji, nanyang and Oriental electric, and four types of generators. The existing tools are various in types, most of the tools are only suitable for a single machine type, and the tools suitable for various machine types are fewer, so that the tools are required to be frequently manufactured for fan operation and maintenance, and the cost is increased.
Taking an eastern electric 1.5MW fan generator set as an example, the existing centering tool has 4 independent parts, wherein two parts are of a T-shaped structure, and two parts are of an F-shaped structure. When the wind generating set is centered, the two F-shaped tools are firstly respectively installed on the foundation bolts on the inner side of the elastic support base of the tail part of the generator, the installation method is that the foundation bolts on the inner side of the elastic support base of the tail part of the generator are taken out, the bolts pass through the middle holes of the F-shaped tools, the bolts are screwed, and the bolts on the tools are adjusted, so that the bolts are clung to the tail part of the generator. Since the nacelle tail is lower than the nacelle middle, this ensures that the generator as a whole will not move backwards when the generator 4 elastic supports are all relaxed. And then, respectively installing the two T-shaped tools on the outer side bolts of the elastic support at the tail part of the generator, wherein the installation method is consistent with the F-shaped tool installation method, but the bolts on the T-shaped tools are required to be propped against the top of the elastic support of the generator.
After the installation is completed, the four elastic supports on the generator are loosened, and according to the data displayed on the centering instrument, the bolts on the T-shaped tool are twisted by using a wrench, so that the bolts are pushed forward to the generator to realize fine adjustment, and the centering adjustment in the horizontal direction is realized.
The inventor finds that the defects of the existing centering tool mainly have two points:
(1) The tool stability is poor:
because the base is arranged under the elastic support of the generator, the stress plane of the T-shaped tool in the centering process is smaller, so that the stability of the tool in the use process is poor, and the centering precision and centering efficiency of the wind generating set are further affected.
The common solution is to lay down an iron plate or other hard tools under the tooling to enlarge the contact area with the tooling, so that the tooling is kept horizontal and stable centering is realized. However, the precision is poor by the method, and the thickness of the elastic support base is small, so that the iron plate or the tool for laying the cushion cannot completely level the tool, the base manufacturing process is rough, and the phenomenon that the heights of the elastic support bases of the same generator are different exists, so that the centering efficiency is influenced.
(2) The application range is smaller, and the method is only suitable for one machine type:
because the elastic support heights of each type of generator are different, and the threaded holes of the mounting bolts on the tool are not adjustable, each type of T-shaped tool is only applicable to one type of generator.
