Abstract

The invention discloses a vertical shaft cutter disc. The vertical shaft cutter disc comprises a middle cutter disc arranged in the middle of a cutter disc and a side block cutter disc arranged at theperipheral part of the middle cutter disc, wherein the side block cutter comprises at least two side blocks which are detachably connected; the middle cutter disc is in blocking connection to the side block cutter disc, so that under a blocking state, the middle cutter disc and the side block cutter disc synchronously rotate, and the middle cutter disc can move upwards relative to the side blockcutter disc under a relieved state. After vertical shaft excavation is accomplished, the middle cutter disc moves upwards for being taken out in a mode of relieving blocking connection between the middle cutter disc and the side block cutter disc, and the side block cutter disc is disassembled and taken out in a mode of relieving connection between the side blocks, so that a take-out process of the vertical shaft cutter disc is convenient and quick, and therefore, damages, caused by cutting the cutter disc, on the cutter disc are avoided. The invention further discloses a heading machine comprising the vertical shaft cutter disc.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment for shaft operations, and more specifically, relates to a shaft cutter head. 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 suppor...
