Description

Technical Field

[0001] The present invention relates to the technical field of installation structures, in particular to a quick installation structure for a shield machine cutter. Background Art

[0002] A shield machine, or TBM, is a specialized engineering machine used for tunnel excavation. It performs functions such as excavating and cutting soil, transporting soil debris, assembling tunnel linings, and performing measurement, guidance, and correction. It involves multiple disciplines and technologies, including geology, civil engineering, mechanics, mechanics, hydraulics, electrical engineering, control, and measurement. Furthermore, its design and manufacturing must be tailored to the specific geology, requiring extremely high reliability. During the life of a project, a shield machine's cutters must be frequently replaced due to changes in excavation position and cutter wear. However, existing shield machines operate in extremely poor environments. To ensure the cutter's stability during excavation, the cutter barrel must be securely mounted. Therefore, the flange structure used to secure the cutter barrel often has numerous mounting holes, requiring numerous bolts for fastening. This results in numerous bolts needing to be loosened during disassembly, resulting in high labor intensity and time-consuming disassembly. Summary of the Invention
