Abstract

The invention discloses a shield tunneling machine cutterhead, a hob used on the shield tunneling machine cutterhead and a shield tunneling machine. The shield tunneling machine cutterhead comprises a cutterhead body and the hob arranged on the cutterhead body; and the hob comprises a base which is fixed on the cutterhead body, a movable caster which is pivoted on the base through a first rotating shaft, and a cutter which is pivoted on the movable caster through a second rotating shaft.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a shield machine cutter head, a hob used on the shield machine cutter head and the shield machine. Background technique [0002] As one of the most commonly used tunneling machines at present, the shield machine has the characteristics of more mechanization and automation than traditional excavation methods, and has the advantages of high efficiency and safety. During the development of the shield machine, the deflection correction of the shield body and the control of tool wear have always been research hotspots. How to improve the rock / soil breaking efficiency of the tool and prolong the service life of the tool has been widely concerned. It is affected by external factors such as geological topography and internal factors such as the operation error of the machine itself. The tunneling of the shield machine cannot always guarantee to run along the design axis, ...
