AI Technical Summary
Technical Problem
In oil pipeline welding, the saddle port of the main pipeline is complicated and the scribe accuracy is not high, resulting in poor cutting quality.
Method used
A pipeline saddle opening cutting device is designed, including a main pipe line, branch pipe section, adjusting pipe section, ring belt and scribe cutting device. The precise cutting of the main pipe line is achieved through adsorption fixation of the ring belt and the adjustment pipe section and laser projection annotation.
Benefits of technology
The device can complete the stake marking and cutting of the saddle mouth at one time, improving the cutting quality and reducing the problem of poor cutting quality caused by inaccurate stake.

Abstract
The invention relates to a pipeline saddle opening cutting device which comprises a main pipeline, a branch pipe section is arranged above the main pipeline, the bottom end of the branch pipe section abuts against the side wall of the main pipeline, an adjusting pipe section is coaxially arranged on the branch pipe section, and a ring belt is arranged in the adjusting pipe section. The ring belt is rotationally connected with a lineation cutting device, and the lineation cutting device cuts the main pipeline. The device has the effects of reducing the situation of poor cutting quality caused by inaccurate lofting and scribing and improving the welding efficiency.
