[0031] Open the support frame 20 so that the upright column to be ground is located inside the support frame 20. Then install the grinding assembly 3 on the guide ring 23. Finally, fix the support frame 20 through the locking member 25. At this time, the grinding assembly 3 fits on the upright column to be ground.

[0032] Step 2: Grinding operation. Energize the grinding drive motor 32 and the slewing drive motor 31 to make the grinder 33 rotate rapidly, and drive the grinder 33 to rotate slowly around the column to be ground under the drive of the slewing drive motor 31, so as to grind the circumference of the column to be ground; after grinding one week, raise or lower the grinding assembly 3 by a certain height through the lifting assembly 1, and repeat the grinding operation. After grinding, just disassemble the locking part 25, and the support frame 20 can be quickly separated from the column to be ground, and finally the device can be disassembled and stored.
