Abstract
The invention discloses a cutter knife for a shield machine, relating to the technical field of cutting tools. The cutter knife comprises a cutter body (1) and a cutter shaft (2), wherein stepped grooves (9) are sequentially and symmetrically arranged on two side surfaces of the cutter body; a main alloy cutting edge (7) and an alloy cutting edge (6) are sequentially and fixedly connected in the stepped grooves (9); auxiliary alloy ball teeth (8) are arranged on the top of the cutter body; alloy cutting blades (4) are fixedly connected on two side surfaces of the cutter body under the alloy cutting edge (6); and alloy column teeth (5) are respectively connected on the front end surface and the back end surface of the cutter body. The cutter knife is penetrated through the stepped hole on the cutter body through the cutter shaft to be rigidly connected with a stepped hole and is arranged on a knife-carrier disk of the shield machine; the main cutting edge made of hard alloy and the auxiliary alloy ball teeth partly face an excavating working surface and rotate along with the knife-carrier disk when the knife-carrier disk rotates; and the working surface like a plough share knocks a furrow to excavate an annular groove and damages, crushes, cuts, strips and loosens large cobble stones.
Description
Technical field
The present invention relates to the cutting-tool engineering field, be specifically related to a kind of shield machine and use cutter.
Background technology
The shield driving construction method is widely used in the tunnel construction, and not only efficient is high for it, safety is good, and economic environmental protection, be the optimal selection of modern tunnel engineering construction, and shield machine is the modern professional equipment of using in the shield driving construction method.Cutter is under the sandy gravel geological conditions, to replace hobboing cutter and scraper to be installed in being used on the cutter head of shield machine dedicated tool that cuts; They or aggregate erection or be arranged separately on the cutterhead and when constructing tunnel by in the injection rock soil layer; Cutterhead is realized revolution under whirligig drives simultaneously; Cutter is knocked continuously draw to cut and peel off dregs and cobble makes its fragmentation; Therefore cutter is in shield machine and position, the contacted forefront of pebble layer, the length in its life-span and the compliance of geological conditions become one of key factor that influences shield machine construction efficient.
Summary of the invention
The invention technical problem to be solved provides a kind of shield machine cutter parts that sufficient intensity arranged, abrasion resistance is good and can adapts to the cobble geological conditions.
For realizing the foregoing invention purpose, the technical scheme that is described below is adopted in the invention:
The shield machine of the invention is used cutter; Comprise cutter hub, cutter shaft, said cutter hub two sides symmetry successively have step groove, and alloy major cutting edge and alloy blade connect firmly successively in step; The cutter hub end face is provided with assistant alloy ball tooth, and the cutter hub two sides are positioned at alloy blade bottom and connect firmly alloy blade; Cutter hub front end face and rear end face connect firmly the alloy column tooth respectively.
Be better implement the invention, said cutter hub is set to rectangle, and the cutter hub bottom, has shoulder hole along the cutter hub width, and cutter shaft is arranged in the shoulder hole and connects firmly with cutter hub.
Further, the four sides of said cutter hub is equipped with wearing layer.
Further, said assistant alloy ball tooth is set at least three rows.
Further, the bottom of said cutter hub is drilled with screwed hole.
Owing to adopted technique scheme, the invention to possess following beneficial effect:
1, cutter according to the invention passes the shoulder hole on the cutter hub and rigidly fixes welding with shoulder hole through cutter shaft; Be installed on the cutterhead of shield machine; Major cutting edge and assistant alloy ball toothed portion by carbide alloy is formed are faced the face that excavates; When cutterhead rotates, revolve round the sun, face is knocked ditch dug with a plow as the ploughshare of ploughing with face excavate out ring-shaped groove, the bulk cobble is scratched smash cutting and peel off loosening with cutterhead.
2, anti-wear performance is good, and impact resistance is big, can effectively improve cutter application life.
3, in the tunnel, change easy accessibility, the similar internal thread pin of bottom thread pore structure, the available instrument that is similar to the pin removal structure disassembles cutter.
Description of drawings
Fig. 1 is the finished product structural representation of the invention cutter;
Fig. 2 is the left view of Fig. 1;
Among the figure: 1, cutter hub; 2, cutter shaft; 3, wearing layer; 4, alloy blade; 5, alloy column tooth; 6, alloy blade; 7, alloy major cutting edge; 8, assistant alloy ball tooth; 9, step groove; 10, shoulder hole; 11, screwed hole.
The specific embodiment
The invention is explained further that what need explanation is that the invention is not limited to following embodiment below in conjunction with accompanying drawing.
In conjunction with Fig. 1 and Fig. 2, the shield machine of present embodiment is used cutter, comprises cutter hub 1, cutter shaft 2, and cutter hub 1 is set to rectangle, and the cutter hub bottom, has shoulder hole 10 along the cutter hub width, and cutter shaft 2 is arranged in the shoulder hole and connects firmly with cutter hub 1.Cutter hub two sides symmetry successively have step groove 9, and alloy major cutting edge 7 is welded in the step groove with alloy blade 6 successively; The cutter hub end face studs with assistant alloy ball tooth 8; The cutter hub two sides are positioned at alloy blade 6 bottom welding alloy blades 4; Cutter hub front end face and rear end face connect firmly alloy column tooth 5 respectively.
For strengthening continuous application life of cutter hub and cutting intensity, wearing layer is all arranged at the four sides of cutter hub 1; Assistant alloy ball tooth 8 is set at least three rows.
For ease of the replacing dismounting of cutter, the bottom of cutter hub 1 is drilled with screwed hole 11.
Cutter according to the invention directly acts on sandy gravel stone or soil layer face as a crucial tool parts of shield machine driving excavation, through the continuous rotation of cutter head of shield machine, makes cutter continuously cut face, realizes continuous excavation operation.
