CN201318179Y - Disk cutter capable of being mounted in forward inclining manner in full face tunnel boring machine - Google Patents

Abstract

The utility model belongs to disk cutter equipment, and particularly relates to a disk cutter capable of being mounted in a forward inclining manner in a full face tunnel boring machine. Four disk cutter mounting bases are arranged on the inner wall of the cutter head; a bracket and a disk cutter which is supported by the bracket are arranged on each disk cutter mounting base; the plane surface on which the edge of the disk cutter is positioned forms an included angle Epsilon i with the direction of kinematic velocity of the axes transport motion. Due to the adoption of the disk cutter, the slip value and the abrasion of the disk cutter are effectively reduced, the service life of the disk cutter is prolonged, the project construction cost is reduced, and the project construction period is shortened; the structure is simple, the manufacture is convenient, and the cost is low.

Description

The disk cutter that complete-section tunnel boring machine leans forward and installs

Technical field

The utility model belongs to disc cutter device, the disk cutter that particularly a kind of complete-section tunnel boring machine leans forward and installs.

Background technology

The installation of disk cutter on cutterhead all is just to install on the cutterhead of complete-section tunnel boring machine plane at present.Adopt this mounting means, according to engineering statistics, the consumption costs of cutter be about construction costs about 1/3rd and change the time that cutter spends and be about about 1/3rd of the duration of a project, wherein the cutter consumption more than 80 percent since tool wear causes.The wearing and tearing of disk cutter on the cutterhead of plane are mainly caused by its sideslip through the theoretical calculate proof, thereby, preventing the sideslip of disk cutter in construction, the life-span of improving disk cutter is important research project in the engineering practice.

Summary of the invention

The present invention is directed to the disk cutter just installed quick abrasion in use, the shortcoming that the life-span is short has proposed the lean forward disk cutter of mounting means of a kind of employing that is used for complete-section tunnel boring machine.It is characterized in that cutterhead 4 inwalls are provided with 4 disk cutter mount pads 3; Carriage 2 is set on disk cutter mount pad 3, and the disk cutter 1 that supports by carriage 2; The angle of the plane, blade place of disk cutter 1 and its axis transport motion velocity attitude is ε.

The angle of the plane, blade place of described disk cutter 1 and its axis transport motion velocity attitude ${\mathrm{\&epsiv;}}_i=\mathrm{<figure-callout\; id="2"\; label="arcsin"\; filenames="Y20082012478600061.png"\; state="\{\{state\}\}">arcsin</figure-callout>}\frac{\sqrt{2\mathrm{rh}-{\mathrm{<figure-callout\; id="2"\; label="h"\; filenames="Y20082012478600061.png"\; state="\{\{state\}\}">h</figure-callout>}}^2}}{{2R}_i},$ Wherein, r is the disk cutter radius, R _iBe the installation radius of disk cutter on cutterhead, h is the average cutting-in of disk cutter.

The implementation of the angle ε of the plane, blade place of described disk cutter 1 and its axis transport motion velocity attitude is: the position of disk cutter mount pad 3 is about the cutter diameter symmetry, the position of screw 5 is the center with mount pad to the center of holding, along cutterhead rotation direction rotation ε angle; Perhaps the position of disk cutter mount pad 3 is the center with it to the center of holding, along cutterhead rotation direction rotation ε angle.

The beneficial effects of the utility model are: use the utility model can effectively reduce disk cutter sideslip amount and wearing and tearing, in the life-span of improving disk cutter, reduce the engineering construction cost, shorten the duration of a project; Simple in structure, easily manufactured, cost is low.
