Abstract

The invention discloses a corrugated rock tunnel boring machine cutterhead with a free surface assisting in rock breaking and a preparation method thereof. The cutterhead comprises a corrugated cutterhead panel. The corrugated cutterhead panel is provided with a wave crest area, a wave trough area and a transition area, wherein the wave crest area and the wave trough area are annular surfaces in space, the transition area is a closed curved surface in space, the conical surface of the closed curved surface is cut by two planes where the wave crest area and the wave trough area are located, andthe three planes in space are sequentially connected to form the corrugated cutter head panel. A central hob is mounted at the central position of the corrugated cutterhead panel. An edge hob is mounted at the edge of the outermost ring of the corrugated cutter head panel. Positive hobs are installed in the wave crest area, the wave trough area and the transition area of the corrugated cutterheadpanel. By improving the cutterhead panel, the rock breaking efficiency of the heading machine can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of rock tunnel boring machines, and in particular relates to a corrugated rock tunnel boring machine cutterhead with a free surface assisting rock breaking and a preparation method thereof. Background technique [0002] Full-face rock tunnel boring machine is the preferred equipment for excavating long-distance rock tunnels. Compared with the traditional drilling and blasting method, it has significant advantages such as safety, speed, and environmental protection. Therefore, it is widely used in underground transportation, water diversion projects, and high-speed railways. . [0003] The cutter head is the key component of the rock tunnel boring machine. It has the basic functions of breaking rock and excavating rock debris, and has the most direct impact on the tunneling efficiency. The rock-breaking mechanism of the full-face rock tunnel boring machine is as follows: the hob continuously rolls the rock o...
