Abstract

The invention discloses a shield machine and a cutter head thereof. The cutter head comprises a cutter head frame, a plurality of main spoke arms and normal-pressure replaceable cutter assemblies. The cutter head frame is provided with a front working surface; a normal-pressure cavity with an inlet and an outlet is defined in each main spoke arm, and the inlets and the outlets are formed in the rear side of the cutter head frame; the normal-pressure replaceable cutter assemblies comprise mounting seats, detachable cutters and replacing components, the cutters and the replacing components are arranged on the mounting seats in such a manner that the cutters and the replacing components can be relatively repositioned in the front-back directions in a switched manner, the normal-pressure replaceable cutter assemblies are arranged on the front surfaces of the main spoke arms, and the replacing components are positioned on the rear sides of the cutters when the cutter head works, so that the cutters can be spaced from the normal-pressure cavities; the replacing components are positioned on the front sides of the cutters when the cutters need to be replaced, so that the cutters can be communicated with the normal-pressure cavities, and the normal-pressure cavities can be spaced from a environment where the front working surface of the cutter head is positioned. The shield machine and the cutter head have the advantages that operators can conveniently enter the normal-pressure cavities, the cutters can be replaced in normal-pressure environments, and accordingly the personal safety of the operators can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a cutterhead of a shield machine and a shield machine. Background technique [0002] The cutter head of the existing large-diameter mud-water balance shield machine is mainly equipped with replaceable hobs and cutting tools under pressure. Under the high-pressure environment of the mud tank, the tool change process is time-consuming and expensive, and the improper operation of the step-up and step-down process can easily cause permanent damage to the health of the operator. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a cutter head of a shield machine, which can realize the operator's tool change under normal pressure and ensure the personal safety of the operator. [0004] The present invention also proposes a shield...
