Abstract
The utility model discloses shield structure tearing cutter, it comprises connecting portion, the cutter hub be fixedly connected on connecting portion that the hobboing cutter girff on cutter head of shield machine removably connects.The utility model shield structure tearing cutter, adopts the tearing cutter of changeable type, utilizes original hobboing cutter girff, removed by hobboing cutter and adopt the mode of bolton to configure replaceable tearing cutter, improve the utilization rate of cutter head of shield machine, improves driving speed.
Description
Technical field
the utility model relates to a kind of shield structure tearing cutter, particularly relates to a kind of removable shield structure tearing cutter.
Background technology
shield method is a kind of construction method at underground bored tunnel, shield machine is the construction equipment of the topmost uniqueness of this construction method, be one and possess several functions in the comprehensive equipment of one, it gathered in construction of tunnel excavate, be unearthed, function that supporting, slip casting, guiding etc. are whole.Functionally comprise excavation system, main drive system, propulsion system, slag-tapping system, filling system, grease system, hydraulic system, electrical control system, automatic guiding system and ventilation, water supply, electric power system, harmful gas detecting device etc.
cutter head of shield machine is the capital equipment component in shield machine excavation system, is also the core component of shield machine, its intensity and integral rigidity all directly have influence on speed and the cost of construction driving, and the maintenance process difficulty that is out of order.Cutterhead is one and is positioned at the forefront of shield machine with the cutting disk body of multiple feed well, for cutting the soil body.It is a shaver that the operating principle of cutterhead can simply be compared to, in advance process, gradually earth sandstone is become fragment, then is discharged in " storage room " after cutterhead.
shield machine cutter is the main tool of shield tunneling, grasps the choice and operation method that it is correct, cutterhead is reasonably arranged, for improve shield structure drivage efficiency, to create good economic benefit most important.Shield structure can run into different stratum in work progress, from mud, clay, layer of sand to soft rock and hard rock.Cutter cutterhead can not be machine-made, must carry out personalized designs according to engineering geological condition.Shield machine tearing cutter rotates with cutterhead and do not have the broken rock cutter of rotation, that while shield machine is pushed ahead, cutter rotates forward shearing force and radial direction (cutterhead rolling tangential direction) cutting force of the excavation face soil body being produced to axially (along tunnel direction of advance) with cutterhead, constantly excavation face front soil cutting is got off, be generally applicable to the scalls such as sandy gravel, sand, clay.
shield machine, in tunneling process, needs with the continuous change of landing surface and adopts different knife disc tools, and therefore cutter head of shield machine is when designing, and cutter head structure exists often simultaneously the cutter of several dissimilar and function.Hobboing cutter must be adopted in hard rock tunneling process as main cutting tool, but be then not suitable for adopting hobboing cutter to tunnel at scalls such as sandy gravel, sand, clays.Hobboing cutter is in idle state in above-mentioned stratum, reduces the drivage efficiency of shield machine, causes claim for eot, and cost improves.
Summary of the invention
in order to solve the problem, the purpose of this utility model is to provide a kind of shield structure tearing cutter.
in order to reach above object, the technical solution adopted in the utility model is: a kind of shield structure tearing cutter, and it comprises connecting portion, the cutter hub be fixedly connected on connecting portion that the hobboing cutter girff on cutter head of shield machine removably connects.
further, connecting portion has screwed hole, connecting portion is removably connected on hobboing cutter girff by bolt.
further, the material of cutter hub adopts 40CrNiMo.
further, cutter hub have alloy brazed portion and build-up wear-resistant layer.
further, KE13 selected by the alloy material in alloy brazed portion.
further, build-up wear-resistant layer thickness is 5mm ± 1mm.
owing to adopting technique scheme, the utility model shield structure tearing cutter, adopt the tearing cutter of changeable type, utilize original hobboing cutter girff, hobboing cutter removed and adopts the mode of bolton to configure replaceable tearing cutter, improve the utilization rate of cutter head of shield machine, improving driving speed.

number in the figure is:
1, connecting portion; 2, cutter hub; 3, screwed hole; 4, alloy brazed portion; 5, build-up wear-resistant layer; 6, blade.
Detailed description of the invention
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
embodiment one
as can be seen from the structural representation of accompanying drawing 1 and accompanying drawing 2, the present embodiment illustrates for twolip tearing cutter, a kind of shield structure tearing cutter, it comprises connecting portion 1, the cutter hub 2 be fixedly connected on connecting portion 1 that the hobboing cutter girff on cutter head of shield machine removably connects.Cutter hub 2 has two blades 6.
connecting portion 1 has screwed hole 3, connecting portion 1 is removably connected on hobboing cutter girff by bolt.
cutter hub 2 have alloy brazed portion 4 and build-up wear-resistant layer 5.
build-up wear-resistant layer 5 thickness is 5mm.
for strengthening abrasion resistance and the globality of tearing cutter, the basis of original tearing cutter is improved, cutter hub material adopts 40CrNiMo(forging), KE13 selected by the alloy material in alloy brazed portion 4, the welding manner of alloy adopts the soldering of medium-high frequency money base, and alloy flexural strength is more than or equal to 2800mPa, and the hardness of alloy is HRA87-88, build-up wear-resistant layer 5 thickness is 5mm ± 1mm, and build-up wear-resistant layer 5 hardness is more than or equal to HRC58.
embodiment two
shield structure tearing cutter in the present embodiment is single-blade tearing cutter, and the difference of itself and embodiment one is only: cutter hub 2 has a blade 6.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
