Abstract

The invention discloses a drilling and splitting sealed cutter head, which solves the problem of low driving efficiency when the TBM cutter head excavates hard rock in the prior art. The invention comprises a cutter head, the cutter head is provided with an axial installation hole and a hob, an anchor drill splitting device and an opening and closing sealing device for sealing the axial installation hole are arranged in the axial installation hole, the anchor drill The splitting device can protrude from the opening and closing sealing device and can move back and forth along the axial mounting hole. The invention effectively prevents ballast from entering the installation hole by opening and closing the sealing device, protects the anchor drill splitting device, and further improves construction safety. The anchor drill splitting device well integrates the anchor drill, splitting and cutter head to ensure that drilling and splitting can be carried out efficiently, improve the efficiency of auxiliary rock breaking, and does not affect the original excavation function of the cutter head, reducing TBM cutter head roll Knife wear for efficient tunneling.

Description

technical field [0001] The invention relates to the technical field of roadheaders, in particular to a drilling and splitting sealed cutter head. Background technique [0002] Rock tunnel boring machine (TBM) is a large-scale tunnel excavation equipment integrating mechanical, electronic, hydraulic, laser and other technologies. It plays an important role in the construction of mountain tunnels and urban subway projects. However, when encountering high-strength rocks, such as granite, marble, etc., the efficiency of TBM excavation decreases significantly, and the loss of tools is huge, and the construction cost increases. And existing excavation equipment such as application number is a kind of excavation anchor drill integrated hard rock roadheader of CN201410760991.3 and application number is a kind of composite splitting machine of CN201711130728.6 and can be used for the excavation of hard rock, but with existing The integration of TBM is poor. How to use anchor drillin...
