Abstract
The utility model relates to a super-wear-resistant shield cutter, which is used for tunneling of shield machines for subways and tunnels and other trenchless tunneling engineering. The super-wear-resistant shield cuter is mainly characterized in that two rows of strip-shaped alloys are added on the basis of an original shield cutter, simultaneously, an original cylindrical alloy is changed into two or more strip-shaped alloys, and end surface alloys are added on two end surfaces of the shield cutter, so that the novel super-wear-resistant shield cutter can be manufactured via brazing. The super-wear-resistant shield cutter can be favorable for digging and cutting trenchless engineering containing cobble and sandstone geologic structures during working, not only resolves the problem of cutting of a front-row edge, but also resolves the problem that a back angle surface of the cutter is worn due to flowing of dregs and is not wear-resistant, and achieves effects of fast tunneling speed and long service life. The utility model can be widely applied to similar shield cutters.
Description
Technical field
The utility model belongs to shield structure bite field.
Background technology
Shield structure cutting tool is mainly used in the shield machine driving in subway, tunnel; its structure is a cylindric alloy more than the front of cutter hub welding one row or two arranges; this structural arrangement alloy is unfavorable for the cutting driving of cutter, and not wear-resisting, can not do effective protection to cutter hub.
When shield cutter along the circumferential direction rotates with cutterhead, begin cutting, cutter hub rapid wear and the alloy phenomenon of bursting apart appears when meeting sandy gravel easily, but when rotating counterclockwise, the back is subjected to the heavy wear of rock, will cause to impact master alloying after the heavy wear of cutter hub dorsal horn face and cause cutter to scrap.
Summary of the invention
The purpose of this utility model is unfavorable for the cutting driving of cutter for overcoming present unreasonable products structure, not wear-resisting defective, and a kind of structure uniqueness is provided, the cutting that is beneficial to cutter is tunneled and wear-resisting shield cutter.
The utility model is achieved in that
The utility model is made up of shield structure cutter hub (1), main cutting alloy (2), strip or cylindric alloy (3) (4), end face alloy (5), it is characterized by, several alloy grooves of processing on shield structure cutter hub, form through brazing alloy (2), (3), (4), (5), main feature is newly-increased two row's strip alloys on the basis of former shield cutter, and at newly-increased two bulk alloys of the both ends of the surface of shield structure cutter hub, simultaneously original cylindric alloy is changed to two or more strip alloy, be made into a kind of novel super wear-resisting shield cutter through soldering.
After the utility model adopts said structure, further strengthened the cutting power of shield structure cutter, effectively protected cutter hub again, thereby realized that the cutter hub abrasion resistance strengthens greatly.Wherein the use of main cutting alloy (2) has improved cutting power on the basis of former shield cutter; The use of alloy (3), (4), (5) has strengthened the abrasion resistance of cutter hub on the basis of former shield cutter, the raising of combination property has guaranteed the driving distance of shield machine, and has effectively prolonged the application life of shield cutter.

The specific embodiment
Elaborate below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5,6 pairs of examples of the present utility model of accompanying drawing:
As accompanying drawing Fig. 1, shown in Figure 2, the utility model is a kind of novel super wear-resisting shield cutter, main feature is newly-increased two row's strip alloys on the basis of former shield cutter, and at newly-increased two bulk alloys in the two ends of shield structure cutter hub, simultaneously original cylindric alloy is changed to two or more strip alloy, become a kind of novel super wear-resisting shield cutter through the soldering making, wherein shield structure cutter hub (1) is used for the driving of shield machine, main cutting alloy (2) is mainly used in shear action, bar shaped (cylindrical) alloy (3), (4) mainly play wear-resisting effect, prevent the heavy wear of shield structure cutter hub (1), end face alloy (5) mainly plays wear-resisting effect, prevent the end wear of shield structure cutter hub (1), above-mentioned alloy (2), (3), (4), (5) can adopt following layout architecture:
1, main cutting alloy (2) is that big round or band relief angle alloy cooperate with the right angle solder side of (1), and alloy (3) is cylindric alloy, and both ends of the surface can be added end face alloy (5), as shown in Figure 3.
2, main cutting alloy (2) is big round or band relief angle alloy, and alloy (3) is cylindric alloy, and alloy (4) is the triangular shape alloy, cooperates (1) associated welds face, and both ends of the surface can be added end face alloy (5), as shown in Figure 4.
3, main cutting alloy (2) is big round alloy, and alloy (3), (4) can be rectangular-shaped alloy, cooperates (1) associated welds face, and both ends of the surface can be added end face alloy (5), as shown in Figure 5.
4, main cutting alloy (2) is big chamfering prismatic shape alloy, and alloy (3), (4) can be the triangular shape alloy, cooperates with corresponding (1) solder side, and both ends of the surface can be added end face alloy (5), as shown in Figure 6.
The alloy of above-mentioned multiple layout architecture (2), (3), (4), (5) can be made up mutually, to form another new super wear-resisting shield cutter combination, to adapt to different service conditions, satisfy different clients' instructions for use.
The utility model can be widely used on the similar shield cutter.
