Description
Technical field
The utility model is related to shield machine field more particularly to a kind of shield double-edged hobbing cutters.
Background technology
Shield method is a kind of construction method in subsurface bored tunnel, and shield machine is the most important of this construction method
Unique construction equipment is one and has multiple functions in the comprehensive equipment of one, it, which has gathered in Tunnel Engineering, excavates, goes out
The function of the whole such as soil, supporting, slip casting, guiding.Include functionally excavation system, main drive system, propulsion system, go out slag system
System, filling system, grease system, hydraulic system, electric control system, automatic guiding system and ventilation, water supply, power supply system,
Harmful gas detecting device etc..Cutter head of shield machine is the core of the capital equipment component and shield machine in shield machine excavation system
Center portion part, its intensity and overall stiffness all directly influence the speed and cost of construction driving, and the maintenance process that is out of order
It is difficult.Cutterhead is a cutting disk body for carrying multiple feed wells, is located at the forefront of shield machine, for cutting the soil body.Cutterhead
Operation principle can simply be compared to be a shaver, soil sandstone is gradually become into fragment during advancing, then is discharged
In " storeroom " after to cutterhead；Shield machine cutter is the main tool of shield tunneling, grasps its correctly selection and user
Method is reasonably arranged on cutterhead, most important for the drivage efficiency, the good economic benefit of creation that improve shield.
Shield can encounter different stratum in the construction process, from mud, clay, layer of sand to soft rock and hard rock.Cutter cutterhead can not possibly
It is machine-made, it is necessary to which personalized designs are carried out according to engineering geological condition.
Hobboing cutter is the important composition component in shield machine, is mainly used in being crushed, hard rock, is a kind of simple in structure, broken rock
The cutter that amount is big, efficiency of breaking rock is high.But its abrasion is also quickly, the double-edged hobbing cutter especially at cutterhead edge, due to two
Stress to blade is different, and the degree of wear also differs, and causes the waste to blade.In addition, in order to improve the broken effect of hobboing cutter
The hard alloy columnar of small shape is generally fixed on cutter ring and is used as cutter tooth, in general, this fixed form is by rate：It is set on cutter ring
Groove is set, alloy column is pressed into a groove by snap fit, although securely difficulty of processing is very big for operation in this way, is produced into
This height.
Utility model content
In order to solve the shortcoming present in above-mentioned technology, the utility model provides a kind of shield double-edged hobbing cutter.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of shield double-edged hobbing cutter, including
Cutter hub, the first cutter ring and the second cutter ring, the cutter hub, the first cutter ring and the second cutter ring are an integral structure；First cutter ring
Positioned at cutter hub front end, the second cutter ring is located at cutter hub rear end, and the diameter of the first cutter ring is less than the diameter of the second cutter ring；First knife
Circle is not connected with each other with the second cutter ring, and the cutter hub of the first cutter ring and the second cutter ring compartment is recessed inwardly.
Further, be embedded with multiple cutters tooth on first cutter ring and the second cutter ring, the cutter tooth along the first cutter ring or
Second cutter ring equidistantly distributes, and the first cutter ring is exposed in end or the second cutter ring forms hemispheric protrusion.
Further, silver soldering layer is equipped between the cutter tooth and the first cutter ring and the second cutter ring, the thickness of the silver soldering layer is
0.5~1mm.
Further, the cutter tooth on first cutter ring or the second cutter ring has two rows, two rows of cutters tooth to be staggered respectively.
Further, second cutter ring is located at the cutter tooth of cutter hub rear end, and the portion perimeter of each cutter tooth protrusion cutter ring is set
There are silver soldering circle, the silver soldering layer of the silver soldering circle and cutter tooth and the second cutter ring to be structure as a whole.
The utility model is by the settings of two different cutter rings of diameter, when hobboing cutter body rotation, the first cutter ring and second
Speed discrepancy is formed between cutter ring, so that the first cutter ring and the second cutter ring is formed relative motion, and then realize the thorough crushing to rock mass,
The inconsistent problem of the hob abrasion degree at cutterhead edge is overcome simultaneously；It is connected using silver soldering layer between cutter tooth and cutter ring, silver
Layer is more common, and soldering is more secured, overcomes indentation and is fixed difficulty of processing greatly with disadvantage of high cost, increases using the longevity
Life；Cutter tooth on first cutter ring and the second cutter ring is staggered, and can more improve the efficiency of rock crushing；For being located at hobboing cutter
The cutter tooth of rear end reinforces it using silver soldering circle, can be more wear-resisting, increases the service life used, reduces abrasion and replaces.
The double-edged hobbing cutter of the utility model considerably increases the service life and crushing efficiency of hobboing cutter, reduces drain on manpower and material resources, tool
There is good practical function.
