Abstract

The invention discloses a cutter disc of a shield tunneling machine and the shield tunneling machine. The cutter disc comprises a cutter disc frame which is provided with a front working face, main spoke arms, box type spoke arms and normal-pressure exchanging type cutter components. The box type spoke arms are arranged between every two adjacent main spoke arms and define normal-pressure cavities with inlets and outlets. Each normal-pressure exchanging type cutter component comprises an installation seat, a detachable cutter and a switching part. An installation cavity for installing of a cutter is formed in each installation seat, and the front and back relative position of the cutter and the corresponding switching part can be arranged on the installation seat switchably. Each normal-pressure exchanging type cutter component is arranged on the front surface of the corresponding box type spoke arm. When the cutter disc works, the switching parts are located on the rear sides of the cutters to separate the cutters from the normal-pressure cavities; when the cutters are exchanged, the switching parts are located on the front sides of the cutters, so that the cutters are communicated with the normal-pressure cavities, and the normal-pressure cavities are separated from the surrounding of the front working face of the cutter disc. By means of the cutter disc, operators can exchange the cutters in the normal-pressure environment.

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 tool change by the operator under normal pressure, which facilitates the tool change and ensures the personal safety of the operator. [0004] The...
