Abstract

The invention relates to the technical field of a full section rock heading machine, in particular to a variable thickness full section rock heading machine cutterhead. The variable thickness full section rock heading machine cutterhead adopts edge supporting, when the center deflection of the cutterhead is 0, and t0 is obtained according to the relationship between the cutterhead center thicknesst0 and the thickness t1 of the cutterhead supported position; and t1 is determined by an existing determination method for the thickness of a cutterhead of a constant thickness full section rock heading machine or determined according to a cutterhead strength theory. The variable thickness full section rock heading machine cutterhead aims to solve the technical problem of poor deformation uniformity of the cutterhead when the full section rock heading machine carries out heading operation in the prior art.

Description

technical field

[0001] The invention relates to the technical field of full-section rock boring machines, in particular to a variable-thickness full-section rock boring machine cutter head. Background technique

[0002] Full-face rock tunnel boring machine (abbreviated as TBM) is a large-scale underground construction equipment integrating machinery, electricity and hydraulics with high technology intensity. It is mainly used for railways, highways, water conservancy and hydropower diversion tunnels, subways and underground engineering tunnels Excavation building construction. The full-face rock boring machine can alternately complete the excavation and stepping work, and can realize the continuous operation of excavation and ballasting, and deliver the excavated ballast to the belt conveyor through the head of the cutterhead, and transport it out of the tunnel.

[0003] At present, cutterheads of equal thickness are used on full-face rock tunneling machines, and the front ...
