[0002] At present, due to regional differences, tunnel specifications in various regions are different. For example, for subway tunnels, different specifications of tunnels lead to inconsistent pitch circles of tunnel segments. When designing a shield machine, it is generally required that the pitch circle of the thrust cylinder end be the same as that of the tunnel segment.
[0003] At present, in shield machine modification designs, for example, when the shield machine adapts to the segment angle change from 6600 / 5900-1500-22.5° to 6700 / 6000-1500-22.5°, or when the customer requires the shield machine to be compatible with two segments of adjacent specifications, the shield machine's passive articulated propulsion cylinder limit device cannot adjust the propulsion cylinder pitch circle radius. This means that when modifying the propulsion system, the original structure needs to be removed and a new limit device needs to be manufactured and installed, which is time-consuming and labor-intensive.
