Abstract
The utility model discloses a hob cutter ring of a shield machine, comprising a cutter ring frame (5); the surface of the cutter ring frame (5) is provided with a wearable compressive layer (6) which is inserted with more than one diamond composite sheet (7), a diamond-impregnated block (8) and diamond crystal combination (9). The utility model provides the hob cutter ring of the shield machine with extrusion resistance, abrasive resistance and long service life, which is widely applied to the shield machine for excavating tunnels.
Description
Technical field
The utility model relates to a kind of shield machine roller cutter cutter ring that adopts multiple material to be composited, and is applied on the shield machine of tunneling.
Background technology
Now, building subway, tens hobboing cutters generally are being housed on the cutter head of shield machine of tunnel special use.This hobboing cutter cooperates the scraper on the cutterhead, plays shearing, extruding and abrasive action broken formation when the shield machine headwork.The hobboing cutter that uses in the present domestic subway construction engineering adopts the alloy steel manufacturing, and the mode heat treated by case-carbonizing strengthens hardness, can reach about HRC60, but case depth only can reach about 2 millimeters, can not satisfy the requirement of special formation.The failure mode of hobboing cutter mainly is wearing and tearing.The area, Chengdu, 300～400 meters of shield machine drivings, the contact surface abrasion degree of depth of hobboing cutter and sandstone can reach 15～20 millimeters, thereby causes hobboing cutter to lose efficacy in advance than scraper.In the construction of subway, the distance at two stations is often more than 800 meters, and band presses off the storehouse tool changing in the underground tunneling process of shield machine between two stations, and the enforcement difficulty is big, the time is long, expense is high.Therefore, current conditions just needs a kind of hobboing cutter of anti-extrusion, wear-resistant, long service life, to avoid changing hobboing cutter in tunneling process.The critical piece of hobboing cutter wearing and tearing is cutter rings, so in practical operation, only need to change cutter ring and just can achieve the goal.Equally, to excavation railway massif tunnel, when getting through competent bed, there is same problem in the steel body hobboing cutter circle that adopts at present, and drivage efficiency is low, and the life-span is short, also suddenly waits to improve and improves its performance.
The utility model content
That technical problem to be solved in the utility model has provided is anti-extrusion, wear-resistant, a kind of shield machine roller cutter cutter ring of long service life.
The technical scheme in the invention for solving the above technical problem is: a kind of shield machine roller cutter cutter ring, comprise the cutter ring skeleton, and the surface of described cutter ring skeleton is provided with wear-resisting resistance to compression layer, and this wear-resisting resistance to compression layer mainly is made of diamondite.In wear-resisting resistance to compression layer, inlayed going out sword and not going out diamond compact, impregnated with diamond piece and the dimond synneusis of sword more than.
Further say, be embedded with the Buddha's warrior attendant stone composite sheet more than on the described wear-resisting resistance to compression layer.Be embedded with the impregnated with diamond piece more than on the described wear-resisting resistance to compression layer.
Further say, be embedded with diamond compact, impregnated with diamond piece and dimond synneusis more than one on the described wear-resisting resistance to compression layer.
In sum, the beneficial effects of the utility model have:
1, selected the wear-resisting resistance to compression layer of diamondite as cutter ring for use, it is attached to alloy steel skeleton outside, has higher anti-extrusion and abrasive resistance;
2,, and be inlaid with extremely wear-resisting diamond, the application life of having improved hobboing cutter greatly owing to increased special wear-resistant Withstand voltage layer than traditional cutter ring.
Description of drawings
Fig. 1 is the structural representation of hobboing cutter in the utility model;
Fig. 2 is the sectional view of hobboing cutter cutter ring in the utility model.
The specific embodiment
With reference to Fig. 1, the cutter ring 3 of shield machine roller cutter is the vulnerable part of extruding, broken formation, blade 4 be on the cutter ring 3 with the contact site on stratum.Cutter ring 3 is to adopt interference fit to be installed on the shell of bearing 2, and bearing 2 endoporus are equipped with mandrel 1, by mandrel 1 hobboing cutter is assemblied on the cutter head of shield machine.
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
With reference to accompanying drawing 2, preferred embodiment of the present utility model is a kind of shield machine roller cutter cutter ring, comprises cutter ring skeleton 5.The surface of described cutter ring skeleton 5 is provided with wear-resisting resistance to compression layer 6, and wear-resisting resistance to compression layer mainly is made of diamondite.Be inlaid with diamond compact 7, impregnated with diamond piece 8 and dimond synneusis 9 more than one on the described wear-resisting resistance to compression layer.
As mentioned above, just can realize the utility model preferably.Except that the described technical characterictic of manual, be the known technology of those skilled in the art.
Claims (4)
1. a shield machine roller cutter cutter ring comprises cutter ring skeleton (5), it is characterized in that, the surface of described cutter ring skeleton (5) is provided with wear-resisting resistance to compression layer (6).
