[0002] With the acceleration of urbanization process, shield construction plays an important role in various tunnel projects. As the core equipment of shield construction, the utilization rate of shield machine also shows a rising trend year by year. However, with the increase of shield machine usage time, the number of old equipment increases gradually, and the failure rate of main drive also increases.

[0003] In the process of tunnel construction, the main drive, as the core driving component of the shield machine, plays a role in power conversion and output in the process of shield tunnel construction. The failure of the main drive aligning bearing often leads to long-term shutdown of the shield machine, seriously affecting the construction progress and engineering quality, and inevitably encounters the problem of replacing the aligning bearing in the tunnel. The aligning bearing of the main drive is generally assembled with the pinion gear to form a pinion gear assembly, so when replacing the aligning bearing, the entire pinion gear assembly needs to be disassembled and replaced. Generally, the main drive is provided with multiple pinion gears, each of which is assembled with an aligning bearing. When replacing the aligning bearing, the pinion gear needs to be disassembled and replaced. The traditional method of replacing the aligning bearing needs to enter the interior of the main drive, which is not only time-consuming and laborious, but also due to the narrow working space and poor ventilation conditions in the interior of the main drive, workers are easily harmed by dust, noise and other harmful factors when working, and also face potential risks such as mechanical injury and electric shock.

[0004] In addition to the aligning bearing failure, the pinion gear of the main drive may be damaged during the tunneling process of the shield machine, or the drive reducer needs to be increased due to the increase of ground torque, which also requires disassembly and assembly of the pinion gear, and also has the above problems.
