Description
Technical field
The utility model belongs to shield machine field, specifically, relates to a kind of shield machine supersonic spray coating hobboing cutter cutter ring.
Background technology
Cutter head of shield machine is the capital equipment member in shield machine excavation system, is also core component, its intensity and whole of shield machineBody rigidity all directly has influence on speed and the cost of construction driving, and the maintenance process difficulty that is out of order. Cutterhead be one withThe cutting disk body of multiple feed wells, is positioned at the forefront of shield machine, for cutting the soil body. On cutter head of shield machine, be provided with some rollingCutter, whether hobboing cutter reasonably arrange, for improve shield structure drivage efficiency, to create good economic benefit most important. Shield structureIn work progress, can run into different stratum, from mud, clay, layer of sand to soft rock and hard rock.
On shield machine roller cutter, be provided with cutter ring, cutter ring directly contacts with rock stratum, is the direct performance of shield machine performance quality, therefore,Improve serviceability and the quality of shield machine, must first improve the Performance and quality of cutter ring.
Chinese Patent Application No. 201420404430.5, the patent document in open day on December 10th, 2014, discloses a kind of obliqueTooth cutter ring of disc cutter, relates to shield structure hobboing cutter field, and cutter ring matrix is hollow cylinder, and cutter ring matrix is radially evenly offered someTeeth groove, teeth groove opening, is provided with a hard alloy blocks outwardly in each teeth groove, the axis of the center line of teeth groove opening and cutter ring matrixBetween angle be 0～45 °; Hard alloy blocks is L-type, and a limit of hard alloy blocks embeds in teeth groove, and another limit is coveredBe placed on the excircle of cutter ring matrix. The overall wear resistance of this utility model hobboing cutter cutter ring is good, long service life. But this utility modelDisclosed cutter ring complex structure, manufacturing cost is high, is not suitable for mass production promotion.
Chinese Patent Application No. 201420362801.8, the patent document in open day on October 29th, 2014, discloses a kind of shieldIntegral type twolip insert cutter for structure, it comprises cutter hub and cutter ring, cutter hub and cutter ring are integral type structure, cutter hub and cutter ring surfaceHave wearable overlay, cutter ring outer rim is blade, is embedded with multiple multiple cutters tooth that are circumferentially equally spaced along blade, cutter tooth on bladeEnd expose blade, cutter tooth end is hemispherical, it is 35mm ± 2mm that cutter tooth embeds the degree of depth of blade. Above-mentioned owing to adoptingTechnical scheme, integral type twolip insert cutter for this utility model shield structure, on the basis of integral type twolip pointed tooth hobboing cutter, by pointTooth is optimized for knuckle-tooth, has increased the buried depth of cutter tooth, has reduced the length that alloy cutter tooth exposes blade, can effectively prevent that cutter tooth from fractureing,Thicken the hardfacing layer thickness between the cutter tooth of blade top, improved wear-resistant and shock resistance, greatly reduced hobboing cutter cutterTool service life, save cost. But the disclosed technical scheme of this utility model is because each cutter tooth independently arranges, at shield machineDuring to rock out, single cutter tooth stressed more concentrated, relative, the intensity of resisting rock impact increases, and long-term use heldEasily collapse tooth phenomenon, have potential safety hazard.
Chinese Patent Application No. 200920084163.7, the patent document in open day on December 16th, 2009, discloses a kind of useIn the cutter ring of disc cutter of shield machine, include cutter ring body and cutter ring outer rim, its difference is in described cutter ring outer rimUpper by offering teeth groove formation cutting teeth. At cutting teeth flank of tooth surfacing wear-resistant alloy layer. The beneficial effect of this utility model is at cutterCircle outer rim arranges cutting teeth, has changed cutter ring outer rim structure, makes it in the time of work, produce very strong digging force to rock, to replaceThe impulsive force of existing carbide button and the extruding force of naked cutter ring, when cutterhead rotation, the sharp edge of cutting teeth is cut rock and is excavated disengagingRock stratum, realizes incision driving at a high speed, has effectively improved the efficiency of breaking rock of hobboing cutter cutter ring in soft geological rock stratum; At the cutting teeth flank of toothSurfacing wear-resistant alloy layer can significantly improve the wear-resistant and shock resistance of cutting teeth, extends the service life of hobboing cutter cutter ring. But shouldIt is the problem that 201420362801.8 patent document exists that utility model exists Chinese Patent Application No. equally, due to each cutterTooth independently arranges, and at shield machine during to rock out, single cutter tooth stressed more concentrated, relative, resists rock impactIntensity increases, and long-term use easily collapsed tooth phenomenon, has potential safety hazard, easily causes the damage of unrepairable.
