Abstract

The invention discloses a hob layout adjustable cutter disc of a tunnel boring machine and an operation method of the hob layout adjustable cutter disc. The hob layout adjustable cutter disc comprisesa rotary disc structure, wherein the rotary disc structure is sequentially provided with a first-stage rotary disc, a second-stage rotary disc and a third-stage rotary disc from inside to outside; the second-stage rotary disc is rotatably arranged on the peripheral wall of the first-stage rotary disc in a sleeve mode, and the third-stage rotary disc is rotatably arranged on the peripheral wall ofthe second-stage rotary disc in a sleeve mode; a plurality of radial guide rails are fixedly arranged on the first-stage rotary disc, the second-stage rotary disc and the third-stage rotary disc, andeach radial guide rail is provided with a locking mechanism; and each radial guide rail is movably provided with a hob seat, and each hob seat is fixedly provided with a hob. According to the hob layout adjustable cutter disc and the operation method thereof, the technical problem of poor geological adaptability of an existing TBM (tunnel boring machine) can be solved.

Description

technical field [0001] The invention belongs to the technical field of structural design of a boring machine cutter head, and in particular relates to a hob layout-adjustable cutter head for a full-face rock tunnel boring machine and an operating method thereof. Background technique [0002] Full-face rock tunnel boring machine (TBM) is the core equipment for excavating rock tunnels. It is very sensitive to tunnel strata and has poor geological adaptability. For the excavation of tunnel sections under different geological conditions, it is necessary to use roadheader cutterheads of different structures and match corresponding auxiliary equipment to ensure the smooth progress of the excavation work. However, this problem can be solved by replacing the roadheader cutterhead or the whole machine. method, the workload is heavy, and the construction progress will be delayed, which also reflects the disadvantages of the roadheader's poor adaptability to tunnel excavation.
