| description | The utility model belongs to the technical field of a full section tunneling machine, and particularly relates to a full section tunneling machine for changing connection radius between a cutter head and a rotary support of the cutter head. The rotary support of the cutter head of the existing full section tunneling machine is passively pushed into a pin roller contact rollaway nest, wherein the center circle radius r is adjusted to be 0.5-0.7R, and R is the diameter of the cutter head. According to the design scheme, the rigidity of the full section tunneling machine when the cutter head works can be increased, the vibration when the full section tunneling machine runs can be reduced, and the working performance of the tunneling machine can be improved. |
