Abstract

The invention discloses a shield end cover fixed type multi-blade hobbing cutter which comprises a cutter ring, a wedge block, a cutter body, a bearing, a lining and a rotary shaft. A pressure monitoring system is installed in each blade, and different signal lines are adopted to monitor working states of hobbing cutter bodies. By means of the shield end cover fixed type multi-blade hobbing cutter, intelligentization level of the shield cutter is further improved, the service life of the hobbing cutter is prolonged, and a foundation is laid for improvement on the shield cutter. The shield end cover fixed type multi-blade hobbing cutter has the advantages of being low in manufacturing cost, easy to install, remarkable in using effect and the like.

Description

technical field [0001] The invention relates to a fixed multi-blade hob with a shield end cover, in particular to a fixed multi-blade hob with a shield end cover and a rock-breaking pressure conveying device. Background technique [0002] The hobs for shield machines are widely used in shield tunneling construction due to their high rock-breaking efficiency. The existing multi-blade hobs use multiple single-blade hob bodies to fix them together to form multi-blade hobs. When a blade is damaged, the corresponding single-edged hob cutter ring or cutter body can be replaced, and other undamaged blades can be kept, which saves cost; but in construction, most of the cutter damage is because the pressure of the hob exceeds the limit, Or there are difficulties beyond the construction conditions, which greatly affect the service life of the hob. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies in the background t...
