Abstract
The utility model relates to a knife ring of a hob of a shield machine, which belongs to the shield machine fitting field. The utility model mainly comprises a ring-shaped knife ring body which is sleeved on a hob assembly, which is characterized in that a hard alloy block is embedded on the outer circumference of the knife ring body. Under the premise that the whole toughness of the knife ring can not be influenced, the utility model effectively increases the rigidity and percussive power of the knife ring of the hob, thereby the abradability of the knife ring is increased. The utility model has the effect of low damage ratio and long service life, which is applicable to excavate hard rock, silt and various complex geological conditions, and the phenomenon of stalling and eccentric wearing of the knife ring is avoided.
Description
Technical field
The utility model belongs to the shield machine accessory, particularly a kind of improved shield machine roller cutter cutter ring.
Background technology
Shield machine application in recent years is very extensive, is mainly used in the driving in underground construction and tunnel.Hobboing cutter is to be used to the cutter that tunnels on the shield machine, mainly is made up of the cutter ring body, is arranged on the cutterhead by the hobboing cutter assembly, is used for rock is carried out fragmentation and cutting.Import now or homemade hobboing cutter are all made by rigid material, exist the problem that wears no resistance, and when running into complex geological condition such as hard rock and silt, are prone to technical barriers such as cutter ring stall eccentric wear simultaneously, cause the hobboing cutter damage, influence application life.
Summary of the invention
The shield machine roller cutter cutter ring that provides a kind of abrasion resistance strong is provided the purpose of this utility model.
The utility model is achieved in that
The shield machine roller cutter cutter ring mainly is made up of the endless knife circle body that is sleeved on the hobboing cutter assembly, it is characterized in that: be embedded with hard alloy blocks on the excircle of cutter ring body.
After the utility model adopts said structure, setting-in hard alloy blocks on the excircle of cutter ring body, under the prerequisite that does not influence the cutter ring overall flexibility, because the effect of hard alloy blocks, the hardness and the attached cutter power of hobboing cutter cutter ring have effectively been improved, thereby improved the anti-wear performance of cutter ring body, had that spoilage is low, the effect of long service life.Be suitable for the driving of hard rock, silt and various complex geological conditions, avoided the generation of cutter ring stall eccentric wear phenomenon.
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, and Fig. 3 is the structural representation of alloy block shown in Figure 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 ring body, 2 is alloy block.
As shown in Figure 1, 2, the utility model is a kind of shield machine roller cutter cutter ring, mainly is made up of cutter ring body 1, and cutter ring body 1 is designed to annular, is sleeved on the hobboing cutter assembly, is used for rock is carried out fragmentation and cutting.Cutter ring body 1 is formed by the steel processing and fabricating, and excircle is got on the bus and is milled with the alloy groove, and this alloy groove evenly distributes on cutter ring body 1.Welding hard alloy blocks 2 in the alloy groove again through bulk heat treatmet and blasting treatment, forms the cutter ring that is embedded with alloy block 2.As shown in Figure 3, the Cross-section Design of alloy block 2 is approximate trapezoid or other shape, is formed by the diamondite material.The shape of this alloy block 2 is corresponding with described alloy groove, guarantees that the two closely cooperates.
During use, cutter ring body 1 is sleeved on the hobboing cutter assembly, and be installed on the cutterhead, rotation along with the hobboing cutter cutterhead, 1 rotation of cutter ring body, revolution, the alloy block 2 of setting-in directly carries out fragmentation and cutting to rock on cutter ring body 1 excircle, when meeting rock, silt or complex geological condition, also but operate as normal has been avoided the generation of stall eccentric wear phenomenon.
Claims (3)
1. the shield machine roller cutter cutter ring mainly is made up of the endless knife circle body (1) that is sleeved on the hobboing cutter assembly, it is characterized in that: be embedded with hard alloy blocks (2) on the excircle of cutter ring body (1).
2. shield machine roller cutter cutter ring according to claim 1 is characterized in that: described alloy block (2) is connected on the cutter ring body (1) by the alloy slot welding, and goes up evenly distribution at cutter ring body (1).
