Summary of the invention
The object of this invention is to provide a kind of cutter head structure for TBM, by to the broken improvement of rock cutter head structure and the optimization of hobboing cutter arrangement, improve the excavation area of broken rock cutterhead, increase the layout quantity of hobboing cutter, to improve efficiency of breaking rock and to reduce cutterhead moment of torsion and thrust.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of cutter head structure for TBM, comprise cutterhead body and be arranged on the hobboing cutter on cutterhead body, described cutterhead body one side is arranged on TBM, opposite side is the scope of operation, and protrude formation work convex surface to operative orientation, installing hole and native stone tap are set respectively on the work convex surface of cutterhead body, installing hole becomes circle distribution, the center of circle of every circle installing hole place circumference is positioned on cutterhead body central axis, between two adjacent circle installing holes, native stone tap is evenly set, described hobboing cutter is arranged in installing hole by cutter shaft, and the tangential direction along described circumference is rotated in installing hole.
Further, the scope of operation of described cutterhead body can be set to sphere.
Further, a group switching centre hobboing cutter group is set at the center of the cutterhead body scope of operation, described central hob group is connected and composed by self cutter shaft successively by a plurality of hobboing cutters, and is arranged in center mounting hole.
Compared with prior art, the present invention has following beneficial effect:
The first, in the present invention, the scope of operation of cutterhead body adopts convex surface, compares with plane cutterhead of the prior art, under equivalent diameter condition, cutterhead of the present invention has larger rock excavation area, therefore, can excavate by the more hobboing cutter of magnitude setting, there is higher efficiency of breaking rock;
Second, in the prior art, rock excavation face is plane, because cutterhead body of the present invention is convex surface, therefore when tunnel is dug, the rock excavation of tunnel forms concave surface towards indent, when the crackle of the rock formation of hobboing cutter squeeze and destroy spreads to surrounding, fragment on concave surface more easily comes off, and especially the fragment at concave surface top is not only subject to the extruding of hobboing cutter, but also is subject to the impact of self gravitation, be easy to split away off from rock mass, therefore, improve the excavation efficiency of TBM, reduced the thrust of TBM;
The 3rd, because the scope of operation of cutterhead body in the present invention is convex surface, and at the beginning of excavation, tunnel rock mass is mostly plane, on cutterhead body, most hobboing cutters cannot touch rock mass, and therefore, the central hob group that is positioned at cutterhead body scope of operation center can be first and rock mass Surface Contact, and by the rotation of central hob group, carry out the excavation of rock mass, to improve efficiency of breaking rock;
The 4th, native stone tap is set, in the present invention between two adjacent rings hobboing cutter in digging process, the native stone being smashed by hobboing cutter can directly fall to the ground, and also can rearward discharge through native stone tap, to prevent that hobboing cutter from being stopped up by native stone, the degree of wear that reduces hobboing cutter, extends its application life.
