[0002] After the PCCP socket steel ring is rounded, a manually operated bridge crane is used to lift the socket steel ring to the bench drill station, and the steel ring is manually lifted up by a cantilever crane and placed on the bench drill to drill the first hole. Then the socket steel ring is rotated 180° to drill the second hole. After completion, the socket steel ring is manually laid down by a cantilever crane, and the manually operated bridge crane is used to lift the socket steel ring to the storage area, and the two holes are tapped manually with a tap. This processing method has the following shortcomings: when turning the hole, the socket steel ring is lifted by a cantilever crane, and the axis of the socket steel ring is parallel to the horizontal plane. The cantilever crane is used to lift the socket steel ring for drilling. The socket steel ring has poor stability, high requirements on workers, and greater difficulty in drilling. At the same time, after the cantilever crane is used to drill the first hole in the socket steel ring, the socket steel ring must be rotated 180° to drill the second steel ring. The operation is relatively cumbersome, the work efficiency is low, and the processing accuracy is difficult to control. On the other hand,

[0003] The socket steel ring is first drilled on a bench drill, and then the socket steel ring is placed flat in a storage area for manual tapping. During this process, the socket steel ring needs to be moved and the placement method changed, and the drilling and tapping are performed separately, resulting in low work efficiency and high labor costs.
