Abstract

The invention discloses a tunneling mechanism suitable for a shield tunneling machine head. The tunneling mechanism comprises a shield tunneling machine body capable of achieving intermittent feeding, a connecting set is fixed to the machine head of the shield tunneling machine body, the tunneling mechanism used for tunneling forwards is arranged on the outer wall, away from the connecting set, of the shield tunneling machine body, and the tunneling mechanism comprises a tunneling head. The tunneling head is arranged on the side, away from the shield tunneling machine body, of the connecting set and fixedly connected with the outer wall of the connecting set through a first hydraulic cylinder, a cutter head is rotationally installed on the outer wall, away from the connecting set, of the tunneling head, a plurality of cutters are installed on the outer wall of the cutter head, and a plurality of sliding grooves are formed in the outer wall of the cutter head. The multiple sliding grooves are distributed in a circumferential array mode, and a sliding block is installed on the inner wall of each sliding groove in a sliding mode. According to the tunneling mechanism suitable for the shield tunneling machine head, through cooperation of the structures, the contact area of the cutter head and soil can be reduced during tunneling every time, and then the tunneling speed and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a tunneling mechanism suitable for the head of a shield machine. Background technique [0002] A shield machine is a tunnel boring machine that uses the shield method. The construction method of the shield is that the tunnel boring machine constructs the shield of the tunnel while excavating, which refers to the supporting segment. It is different from the open construction method. Usually, the tunnel boring machine used for soft ground is called a narrow shield machine. . [0003] The existing shield machines are basically a cylindrical steel component that excavates the soil while advancing along the tunnel axis, but the contact area between the cylindrical steel component and the soil is too large, which will reduce the speed of excavation , thereby affecting the speed of construction. [0004] In view of this, the present invention proposes a tunneling mechanism su...
