AI Technical Summary
Traditional TBM tool and cutter head connection methods are relatively simple and lack flexibility, resulting in low tool replacement efficiency and affecting construction efficiency.
The mounting block and guide groove structure are driven by an electric push rod. The electric push rod moves the mounting block to expose the mounting screws, which facilitates the disassembly and installation of the tool body. Combined with the positioning wedge block and threaded connection, it enables quick replacement.
It improved tool changing efficiency, significantly reduced changeover time, and enhanced the construction efficiency of TBM.
