Abstract

The invention discloses a shaft cutter head, which comprises a middle cutter head arranged in the middle of the cutter head and a side block cutter head arranged on the outer periphery of the middle cutter head, the side block cutter head includes at least two detachably connected side blocks; The cutter head is clamped and connected with the side block cutter head, so that in the clamped state, the middle cutter head and the side block cutter head rotate synchronously, and in the released state, the middle cutter head can move upward relative to the side block cutter head. After the excavation of the shaft is completed, the middle cutter head can be moved upward and taken out by releasing the clamping connection between the middle cutter head and the side block cutter head, and the side block cutter head can be decomposed and replaced by releasing the connection between the side blocks. Take out, so that the removal process of the shaft cutter head is convenient and quick, and avoid the damage caused by the cutting cutter head to the cutter head. The invention also discloses a boring machine comprising the shaft cutter head.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment for shaft operations, and more specifically, relates to a shaft cutterhead. In addition, the present invention also relates to a boring machine comprising the above-mentioned shaft cutter head. Background technique [0002] The common excavation methods for shafts include full-section shaft excavation method and pilot shaft expansion excavation method. When it is necessary to penetrate the strata with high water content and instability, blind shaft construction and rapid well drilling, generally adopt Full-face shaft excavation method. [0003] As one of the key components of the shaft boring machine, the cutter head is mainly used for full-section excavation of the bottom surface of the shaft. When the cutterhead excavates in unstable strata such as weak strata with high water content or sand and pebbles, the well wall must be supported, but no matter what kind of well wall support...
