[0056] The equipment is equipped with a rotating device to make the wind turbine hub rotate with the platform. The platform can be climbed by people to facilitate processing or maintenance of the wind turbine hub. The extension device can make the range of the platform larger, making it more convenient for people to work on larger wind turbine hubs, or directly form a large climbing platform for people to stand on.

[0057] After the reduction motor 91 starts working, it drives the driving gear 94 to rotate.

After that, the second fence 32 is rotated around the vertical part of the first fence 31 to unfold the second fence 32. At this time, the sliding block 44 slides in the guide groove 43 and then moves to the other end of the guide groove 43. Similarly, the same is true when the fourth fence 47 rotates relative to the third fence 46. And the fifth fence 48 can be drawn out from the fourth fence 47 to further extend the blocking range of the fourth fence 47. Through the above operation, the range of the platform can be expanded.

[0060] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
