Description

Technical Field

[0001] This utility model relates to a processing support, specifically to an adjustable inclined support frame for a wind turbine blade hub. Background Technology

[0002] refer to Figure 1 The hub of a wind turbine blade has a sloping end face. When processing the hub, the other end face needs to be adjusted to be horizontal to ensure processing accuracy. Before this invention, there was no suitable processing bracket to support the hub of the wind turbine blade. Utility Model Content

[0003] Based on the content in the background art, in order to facilitate the adjustment of the horizontal state of the wind turbine blade hub, this utility model provides an adjustable inclined support frame for the wind turbine blade hub, which includes two inclined frames arranged opposite each other. The top plate of the inclined frame is inclined, and a jack is provided at the higher end of the inclined frame. The jack is installed on the bottom plate of the inclined frame. The top plate of the inclined frame has a through hole at the corresponding position of the jack, and the top support block of the jack can pass through the through hole of the top plate.

[0004] Furthermore, limit plates are provided at both ends of the inclined frame. The limit plates are detachably connected to the top plate of the inclined frame. The detachable limit plates can be replaced according to different sizes of wheel hub cylinders. Specifically, they are detachably connected to the top plate of the inclined frame by screws.

[0005] Preferably, multiple mounting feet are fixedly connected to both sides of the inclined frame, which facilitates the inclined frame to be mounted on the machine tool by fasteners or by direct welding.

[0006] The working principle of the aforementioned adjustable inclined support frame is as follows:

[0007] When the wind turbine blade hub is mounted on the two inclined frames, the inclined end face of the hub cylinder contacts the top plate of the inclined frame. After the hub cylinder is positioned by the limiting plate, the jack is activated. The top support block of the jack can pass through the through hole of the top plate and abut against the inclined end face of the hub cylinder. Then, the other end face of the hub cylinder can be finely adjusted to a horizontal state by the jack built into the inclined frame to ensure the subsequent machining accuracy of the hub.

[0008] Through the above technical solutions, this utility model has at least the following beneficial effects:

[0009] The adjustable inclined support frame for the wind turbine blade hub described in this application allows the wind turbine blade hub to be easily adjusted to a horizontal state by means of the jacks built into the inclined frames when the hub's cylindrical hoisting device is mounted on the two inclined frames, thus ensuring the accuracy of subsequent processing.
