[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] See also Figures 1 to 4 The utility model provides a tool for removing the hub locking pin of a doubly-fed wind turbine generator set, comprising a support frame 2, on which a U-shaped support groove 3 and an annular disassembly plate 6 fixedly connected to a hub locking pin 1 are fixed, on which a screw 5 parallel to the hub locking pin 1 is threadedly connected, and a positioning bracket 4 for connecting to an outer wall 7 of a hub locking pin cavity is arranged at the rear side of the support frame 2.

[0020] See also Figure 2 and Figure 3 The center point of the annular disassembly plate 6 has a locking pin threaded hole 9, and the locking pin threaded hole 9 is connected to the wheel hub locking pin 1 through a bolt. The bolt is provided in the middle of the wheel hub locking pin 1, and is connected to the annular disassembly plate 6 through this bolt.

[0021] See also Figure 3 The positioning bracket 4 is a U-shaped structure. The U-shaped structure fits the outer wall 7 of the wheel hub locking pin cavity better, and is more convenient to improve the efficiency of removing the wheel hub locking pin 1.

[0022] See also Figure 1 , the positioning bracket 4 is located in the U-shaped supporting groove 3.

[0023] See also Figure 2 and Figure 3 A plurality of threaded holes 8 are provided on the positioning bracket 4. The threaded holes 8 correspond to the threaded holes on the outer wall 7 of the wheel hub locking pin cavity.

[0024] See also Figure 3 and Figure 4 The screw rods 5 are evenly arranged on the annular disassembly plate 6 .

[0025] See also Figure 3 and Figure 4 The screw rod 5 is fixedly connected to the outer wall 7 of the wheel hub locking pin chamber through the threaded hole 8.

[0026] Working principle: The tool is close to the wheel hub locking pin 1, and the positioning bracket 4 is fixed to the outer wall 7 of the wheel hub locking pin chamber through the screw 5. The center point of the wheel hub locking pin 1 is fixed to the annular disassembly plate 6 through the locking pin threaded hole 9 by the bolt, and the 8 screws 5 are rotated diagonally at the same time. By rotating the screws 5, the annular disassembly plate 6 and the outer wall 7 of the wheel hub locking pin chamber produce relative movement to remove the wheel hub locking pin 1 from the chamber. When the wheel hub locking pin 1 is removed to the end, the annular disassembly plate 6 and the screw 5 are removed, and the U-shaped support groove 3 is pushed into the bottom of the positioning bracket 4 to complete the removal of the wheel hub locking pin 1. When reinstalling the wheel hub locking pin 1, the chamber is positioned through the positioning bracket 4 and directly pushed into the wheel hub locking pin chamber.
