Shield tunneling machine cutterhead applied to multi-rock environment

Abstract

The invention discloses a shield tunneling machine cutterhead applied to a multi-rock environment. The shield tunneling machine cutterhead applied to the multi-rock environment is characterized in that the inner ends of a first main spoke arm, a second main spoke arm and a third main spoke arm are connected with one another and distributed in a staggered mode, in this way, working stability is better and stress is more uniform when the cutterhead rotates; in addition, the third main spoke arm is installed on the side far away from a cutterhead frame, in such layout, multiple sixth single-bladehobs on the third main spoke arm can be used for being responsible for main tunneling work, and for tunneling work in the multi-rock environment, the sixth single-blade hobs can guarantee the tunneling speed and quality, the tunneling pressure of the first main spoke arm and the second main spoke arm is shared, and the service live of hobs and cutters on the first main spoke arm and the second main spoke arm can be prolonged. According to the shield tunneling machine cutterhead applied to the multi-rock environment, single-blade hobs, the cutters and advancing cutters are reasonable in layoutand uniform in stress, so that the tunneling efficiency and quality of a tunneling machine in the rock environment are improved, the service life of the tools is prolonged, and accordingly the service life of the tunneling machine is prolonged.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a shield machine cutterhead applied in a rocky environment. Background technique [0002] Dozens of hobs are generally installed on the cutter head of the shield machine dedicated to the construction of subways and tunnels. This kind of hob cooperates with the scraper on the cutter head to shear, squeeze and grind the ground when the shield machine is tunneling. When the cutter head of the shield machine in the prior art is in use, due to the unreasonable layout of the hobs and cutters, the service life of the hobs and cutters is short. The unscientific force on the knife leads to a serious reduction in the efficiency and quality of the excavation. Therefore, it is urgent to develop a shield machine cutter head applied in a rocky environment to solve the problems in the prior art. Contents of the invention [0003] The technical problem to be solved by the present inv...
