Abstract

The invention discloses a drilling and splitting sealing cutter head for solving the problem of low tunneling efficiency when a TBM cutter head in the prior art excavates hard rock. The drilling and splitting sealing cutter head includes a cutter head. The cutter head is provided with an axial installation hole and a hob. The axial installation hole is internally provided with an anchor drilling and splitting device and an opening and closing sealing device for blocking the axial installation hole. The anchor drilling and splitting device can extend out of the opening and closing sealing device and can move back and forth along the axial installation hole. Ballast is effectively prevented from entering the installation hole through the opening and closing sealing device, the anchor drilling and splitting device is protected, and the construction safety is further improved. The anchor drilling and splitting device integrates the anchor drilling, splitting and the cutter head well, the effect that drilling and splitting can be carried out efficiently is ensured, the auxiliary rock breaking efficiency is improved, and the original tunneling function of the cutter head is not affected,so that abrasion of a TBM cutter head hob is reduced, and efficient tunnel excavation is achieved.

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...
