[0002] The hub is an important component in a wind turbine generator. The size of the hub of a wind turbine generator will vary according to its use environment, customer requirements, etc. After the production of the hub of the wind turbine generator is completed, it needs to be placed on the corresponding tooling for operations such as the installation and detection of components. However, the size of the existing placing tooling is fixed and can only support hubs of fixed sizes, with poor versatility. Moreover, when the size of the hub produced in the factory changes, it is necessary to redesign the placing tooling according to the hub size, resulting in a large waste. Content of the Utility Model

[0021] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Please refer to Figure 1 - Figure 2 , a hub placement tooling for a wind turbine generator, including a first support plate 1, on which a second support plate 2 is movably arranged, and a plurality of receiving devices are arranged on the second support plate 2 in a circumferential distribution;

[0023] The receiving device includes a sliding card slot 3 which is opened on the second support plate 2. A sliding plate 4 is slidably clamped in the sliding card slot 3. A receiving plate 5 is fixed on the top of the sliding plate 4, and a docking limit post 6 is fixed on the receiving plate 5.

[0024] The receiving plate 5 is slidably limited on a plurality of sliding limit rods 7. The sliding limit rods 7 are fixed between the first support vertical plate 8 and the second support vertical plate 9, and both the first support vertical plate 8 and the second support vertical plate 9 are vertically and upwardly fixed on the second support plate 2.

[0025] The bottom of the sliding plate 4 is fixed on the piston rod of the adjusting cylinder 10. The adjusting cylinder 10 is horizontally fixed on the third support vertical plate 11, and the third support vertical plate 11 is vertically fixed on the bottom of the second support plate 2.

[0026] In this embodiment, the position of the receiving plate 5 can be adjusted by the adjusting cylinder 10, so that the docking limit post 6 on the receiving plate 5 is correspondingly inserted into the mounting hole on the hub, thus meeting the placement and support requirements of hubs of different sizes.

[0027] A plurality of hydraulic cylinders 12 are vertically and upwardly provided on the first support plate 1, and the piston rods of the hydraulic cylinders 12 are fixedly connected to the bottom of the second support plate 2. In this embodiment, the height of the second support plate 2 can be adjusted by the hydraulic cylinders 12, thereby realizing the adjustment of the support height of the hub, which is convenient for installation, detection, etc.

[0028] A plurality of stabilizing devices are arranged on the first support plate 1 in a circumferential distribution. The stabilizing device includes a fourth support vertical plate 13. A first telescopic cylinder 14 is horizontally arranged on the fourth support vertical plate 13. A fixing plate 16 is fixed on the piston rod of the first telescopic cylinder 14. A second telescopic cylinder 15 is vertically downward arranged on the fixing plate 16, and a stabilizing support plate 17 is fixed on the piston rod of the second telescopic cylinder 15.

[0029] In this embodiment, the placement stability of the entire tooling can be improved by the stabilizing device to prevent tipping, that is, the distance between the stabilizing support plate 17 and the first support plate 1 is adjusted by the first telescopic cylinder 14 to adapt to the placement requirements of hubs of different sizes. After the adjustment is completed, the stabilizing support plate 17 can be attached to the ground by the second telescopic cylinder 15. When the tooling is not in use, the stabilizing support plate 17 can be retracted to reduce the floor area.

[0030] Working principle: Move the wheel hub above the second support plate 2 by a crane and slowly lower it. Adjust the position of the adjusting bearing plate 5 by adjusting the cylinder 10 so that the docking limit posts 6 on the bearing plate 5 are correspondingly inserted into the mounting holes on the wheel hub. This tooling allows the wheel hub not to be placed exactly in the middle of the second support plate 2 (the middle position is the best), thereby reducing the placement difficulty, improving work efficiency, and at the same time, the position of the docking limit posts 6 can also be adjusted according to the size of the wheel hub so that it can be inserted into the mounting holes on the wheel hub, making the tooling more versatile.

[0031] After the placement is completed, if there is an offset, to prevent the tooling from tilting, the distance between the stable support plate 17 and the first support plate 1 can be adjusted and increased by the first telescopic cylinder 14 (the first telescopic cylinder 14 closer to the offset side), thereby improving the stability of the tooling.

[0032] When performing operations such as installation and detection, the height of the second support plate 2 can be adjusted by the hydraulic cylinder 12.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that; still, the specific implementation manners of the present invention can be modified or some technical features can be equivalently replaced; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
