Abstract: The present invention relates to a cutter replacement robot and its adaptive cutter system for tunnel boring machine and belongs to the field of tunnel construction equipment design. Traditional cutter system adopts multi-wedge fastening mode, and the fasteners are many and separate from each other. It is only suitable for manual disassembly and assembly. So, robot can not disassemble and assemble cutter quickly. For the current cutter weight, the current load-weight ratio of industrial robots can not meet the narrow space inside the cutter head of the TBM, so mature industrial robots can not change the all of cutters. Based on the above situation, according to the internal space structure of the cutter head of the TBM, the invention designs a new type of cutter-changing robot and three type cutter systems to realize the rapid disassembly and assembly of the cutter.
