Rice character type structure arrangement method of hobs of full section rock digging machine

Abstract

The invention discloses a rice character type structure arrangement method of hobs of a full section rock digging machine, belonging to the design field of a cutter disk of the full section rock digging machine. Geologic parameters and digging parameters are confirmed according to a geologic report of tunnel engineering, wherein the parameters comprise rock unconfined shear strength, rock uniaxial compressive strength Sigma, rock brazilian tensile strength Sigma Tau, rock stability, digging speed and cutter disk rotate speed. An automatic solve model of the arrangement problem of the hobs on the cutter disk is built, so as to confirm the arrangement position of the positive hobs and the edge hobs with the rice character type arrangement method and a synergetic evolution method. When the hobs are arranged on the faceplate type cutter disk, the technical performance index needs to be met comprises side force to the cutter disk, the overturning moment, interfere area, and the quantity and the mass center of non-order cock fragmentation of the adjoining hobs. The method can fast and effectively confirm the arrangement position of the cutter on the cutter disk, prolong the service lifeof the cutter disk of the digging machine, the cutter and the large bearing of the cutter disk, reduce the shake and the noise of the digging machine, and improve the digging efficiency of the cutterdisk.

Description

technical field [0001] The invention belongs to the field of full-section rock boring machine cutter head design, considers various technical requirements for hob layout design and cutter head manufacturing and assembly process requirements, and particularly relates to a full-section rock boring machine hob M-shaped layout design. Background technique [0002] Full-face rock boring machine (TBM) is a large-scale special-purpose construction machine for tunnel boring, which is widely used in subway, railway, highway, municipal, hydropower tunnel projects, and is expensive. Among them, the layout design of the hob on the cutter head is the core technology of the roadheader design. Reasonable cutter layout plays a decisive role in improving the mining performance of the cutter head, the life of the tool and the life of the large bearing of the cutter head, reducing the vibration of the roadheader, and reducing noise. As a result, if the cutting tool layout is unreasonable, it w...

Problems solved by technology

"This patent only gives the rules that should be followed for the layout of the front hob and the side hob, but it does not consider various technical requirements for the hob layout, such as the requirements for the slag outlet on the cutter head and the requirements for splitting. and manhole requirements, and also does not give an automated design method for determining the position of the hob according to this rule

[0005] To sum up, scholars at home and abroad have made some preliminary research results in the research on the mechanism of rock breaking, the calculation of the force on the cutter head of the roadheader, and the selection of the cutter on the cutter head of the roadheader, but there is no research on the cutting tool from the perspective of layout optimization.
