[0060] A method for using a wind turbine generator set gearbox replacement auxiliary positioning structure comprises the following steps:

[0061] S1: First, place the wind turbine gearbox on the square block 1 and move it using the moving wheels;

[0062] S2: When the gearbox of the wind turbine generator set is placed on the square block 1, the shielding assembly 9 is removed from the inside of the square through hole 8 by human power;

While the shielding plate 91 moves, the plug-in column 92 disengages from the inside of the plug-in groove 93. After disengagement, the extrusion spring 952 gives the rebound block 951 an identical reaction force, so that the shielding plate 91 can be quickly removed. At the same time, after the positioning is completed, the shielding plate 91 needs to be restored to its original position. After the shielding plate 91 is removed, the strong magnet 31 starts to operate. At the same time, the matching block 33 and the matching groove 32 are used in combination to firmly confine the strong magnet 31 to the inside of the square block 1, making its working process more stable and the positioning effect better. Secondly, the auxiliary block 62 is inserted into the inside of the auxiliary groove 61, and then The power source of the entire positioning member 64 is realized by rotating the rotating block 645 by manpower. Because the force can be transmitted, the rotating block 645 drives the threaded rod 644 to rotate inside the threaded groove 643, so that the extrusion block 642 can be pushed to move inside the extrusion groove 641, so that the extrusion block 642 can squeeze the auxiliary block 62, so that the positioning effect of the extension block 63 is better, and the auxiliary support effect is also better. Finally, the groove 71 is used to store the storage box 72, and the storage box 72 is used to store the required tools. When storing, the partition plate 75 is used to separate different tools. Finally, the limit groove 73 and the limit block 74 are used in combination, so that the position of the storage box 72 can be well limited to prevent it from falling off, so that the effect of storing tools is better.
