Embodiment 1

[0069] A where A and I intersect 1 Take area as an example, set this area as the first area, that is, i=1, set the life limit size L of the tool max =397mm, the nominal diameter of the cutter dpD=432mm, the allowable gap between the cutters l=15mm, first replace the cutters with hob diameters d432mm with cutters with diameters 397mm≤d≤432mm.

[0070] A 1 There are 7 knives in the area, arranged in descending order of diameter, numbered 1 to 7 respectively, and the diameters are 430mm, 425mm, 417mm, 414mm, 409mm, 408mm, 398mm. according to d j -d k ≤ l and d j -d k+1 >l, 1≤ji , to find one or more of the largest values a x i = k - j + 1 , 1≤x≤N i -1 criterion, get a 3 1 = 4 , That is to say, for tools numbered 3 to 6, the tools whose diameters d are 417mm, 4...

Abstract

The invention belongs to the technical field of disc cutter management, and especially relates to a management method for disc cutter of full section tunnel boring machine. The method comprises the steps of (1) monitoring the service life of the disc cutter; (2) setting the limit service life value L<max> of the disc cutter and replacing the broken cutter; (3) dividing area for the cutterhead; (4) judging the unqualified cutter; and (5) replacing the unqualified cutter. The method of the invention can scientifically forecast the service life of the disc cutter, correctly forecast the cutter replacing position and cutter replacing time, and not only improves the service life and cutter replacing efficiency of the disc cutter and reduces the construction cost of the full section tunnel boring machine, but also improves the utilization ratio of the full section tunnel boring machine.

Description

technical field [0001] The invention belongs to the technical field of disc hob management, in particular to a method for managing disc hobs of full-face tunnel boring machines. Background technique [0002] The disc hob of the full-section tunnel boring machine is a vulnerable and consumable part in the construction process. Scientifically predicting the life of the disc hob and correctly predicting the position and time of tool change can not only reduce the construction cost of the full-section tunnel boring machine , It can also improve the utilization rate of the full-face tunnel boring machine. [0003] At present, the replacement and management of construction tools of full-section tunnel boring machines is still regular maintenance, and replacement is mainly based on experience, which is not conducive to the reduction of construction costs and the improvement of utilization of full-section tunnel boring machines. Contents of the invention [0004] The present inve...
