[0002] In the production process of shield portal steel ring welding structure, the working hours required for welding steel rings only account for 25%-30% of the processing hours, and the rest of the working time is mostly used for material preparation, assembly and anchor bar positioning, of which anchor bar positioning accounts for 40% of the total processing hours. The traditional anchor bar positioning work requires first assembling the segmented steel rings into a closed ring in the factory, and then determining the longitudinal and transverse spacing of the anchor bars according to the design requirements, and using methods such as elastic lines and distance measurement to determine the specific position of the anchor bars, and then the workers weld them one by one. Since the longitudinal and transverse spacing welding positions of each anchor bar must be accurate to within the set error, the anchor bars need to be repeatedly positioned during the entire welding process, which not only takes a lot of time, but also tests the concentration of the welding workers, resulting in a significant increase in the workers' labor intensity.
