The following steps are included: S1, the second mounting plate (4) is installed on the flange from above the flange, at this time, the fixed plate (408) is located on one side of the inner ring and the outer wall of the flange respectively; S2, the second electric push rod (601) drives the sliding rod (603) to stretch out and retract, which is convenient for adjusting the height of the drilling mechanism on the side of the flange. Then the fixed plate (408) is clamped in the inner ring and the outer wall surface of the flange, and the first mounting plate (1) is fixed on the side of the flange. S3, the first motor (201) drives the moving frame (102) to move up and down, further adjusting the height of the drill bit (302). The second motor (301) is started to drive the drill bit (302) to rotate, and the worker pushes the moving shell (3) to drill holes.
