Abstract
The utility model relates to a disc cutter of a shield machine, and belongs to the accessory of the shield machine. The disc cutter mainly comprises a cutter body. The utility model is characterized in that the cutter body is square; the left end and the right end of the top surface of the cutter body are welded with a large alloy body through an open groove; and the top surface of the cutter body is welded with a small alloy body slightly higher than the top surface of the cutter body through an inner groove. One large alloy body, the small alloy body and another large alloy body contact rock and soil in sequence to process the rock and soil. The disc cutter can effectively replace the original tearing cutter, the rabble blade cutter, the claet tooling and other disc cutters. The large alloy body directly contacts with the rock and soil, thereby preventing the direct wear and tear to the cutter body caused by the rock and soil, effectively protecting the cutter body and preventing the abraded alloy on the cutter body from falling off. The utility model has the advantages of abrasion resistance and long service life.
Description
Technical field
The utility model belongs to the shield machine accessory, is specifically related to a kind of cutter in advance that is installed on the cutter head of shield machine.
Background technology
Shield machine is widely used in operations such as underground construction and tunnel piercing in recent years.The cutterhead of shield machine is provided with cutter, mainly is the rotation that utilizes cutterhead, and by cutter ground, soil layer, sandstone etc. are ditched, rolled, fragmentation and cutting etc., thus finish the engineering driving.According to engine request, cutter generally is divided into scraper, hobboing cutter and the cutter etc. of going ahead of the rest.Cutter is divided into and tears cutter, rake teeth cutter, goat's horn cutter etc. again according to the difference of installation site and effect in advance.Wherein tearing cutter is that a plurality of strip alloys are welded in perforate on the arc cutter hub, and the rake teeth cutter is that a plurality of strip alloys are welded in perforate on rake teeth shape cutter hub, and the goat's horn cutter is two alloys that the welding of goat's horn place is made up of a plurality of alloy blocks at the erietiform cutter hub.Above-mentioned three kinds of cutters all exist cutter hub and expose, and the parcel alloy easily comes off and scraps phenomenon, and application life is short, anti-wear performance is poor.
Summary of the invention
The purpose of this utility model is to provide the high shield machine of a kind of anti-wear performance with the cutter of going ahead of the rest, and replaces original cutter, rake teeth cutter and goat's horn cutter torn.
The utility model is achieved in that
Shield machine mainly comprises cutter hub with the cutter of going ahead of the rest, and it is characterized in that: described cutter hub is square, and two ends are respectively arranged with an open type groove about the cutter hub end face, are welded with big alloy body in the open type groove; Have inner groovy on the cutter hub end face between two big alloy bodies, be welded with the primary alloy body that slightly exceeds the cutter hub end face in the inner groovy.
After the utility model adopts said structure, adopt big alloy body in the end of cutter hub, the centre is provided with the primary alloy body, earlier by a big alloy body contact ground, carry out pre-treatment, by the primary alloy body ground is handled then again, by another big alloy body ground is carried out post processing at last, guarantee operation in advance such as trench digging, fragmentation, can effectively replace original various forms of cuttves in advance such as cutter, rake teeth cutter and goat's horn cutter of tearing.Because big alloy body exposes, and directly contacts ground, has avoided the direct wearing and tearing of ground to cutter hub, has effectively protected cutter hub, avoided because the generation of cutter hub wearing and tearing alloy obscission.Have resistance to wear, the effect of long service life, increased the alloy face, improved the anti-wear performance of cutter hub.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model, and Fig. 2 is the lateral view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
In the accompanying drawing, 1 is that cutter hub, 2 is that big alloy body, 3 is that primary alloy body, 4 is wearing layer.
The utility model is a shield machine cutter in advance, mainly is made of two sides, end face and front/rear ends about comprising rectangle cutter hub 1.As shown in Figure 1, cutter hub 1 side contacts ground in advance in the use, then is end face, is another side at last, and vice versa.The utility model two ends about cutter hub 1 end face are provided with an open type groove respectively, the square big alloy body 2 of welding in the open type groove.The end face of big alloy body 2 exposes and a little less than the end face of cutter hub 1, the side open of big alloy body 2 and a little less than the side of cutter hub 1.Right-angle side or arc-shaped transition limit, chamfered transition limit can be adopted in the top that big alloy body 2 exposes, and also can adopt the mode of integral curved transition or whole trapezoidal transition.Have the bar shaped inner groovy on cutter hub 1 end face between two big alloy bodies 2, welding bar shaped primary alloy body 3 correspondingly in the inner groovy, the end face of primary alloy body 3 slightly exceeds the end face of cutter hub 1.Described primary alloy body 3 vertically is provided with and evenly distribution along the end face of cutter hub 1, generally is designed to three.
For ease of welding, as shown in Figure 2, described big alloy body 2 and primary alloy body 3 can be arranged side by side by polylith primary alloy piece and form, and form square big alloy body 2 and bar shaped primary alloy body 3.
Be the increase anti-wear performance, but other exsertion part spraying wear-resistant materials of the front/rear end of described cutter hub 1, end face and left and right side forms wearing layer 4.
During use, cutter hub 1 is installed in by tool rest on the cutterhead of shield machine, and along with forward and reverse rotation of cutterhead, a big alloy body 2 on the side at first contacts ground, and ground is carried out pre-treatment; Primary alloy body 3 on the end face is handled ground more again then, carries out post processing by 2 pairs of ground of the big alloy body on the another side at last.Because big alloy body 2 exposes and directly contacts ground, has effectively protected cutter hub 1, has avoided the generation of alloy obscission, has improved the anti-wear performance of cutter hub 1.
