Abstract
The invention discloses a hard-rock integral cutter and relates to the technical field of driving in hard rock. The hard-rock integral cutter comprises a cutter shaft, at least one cutter body, a pair of bearings and two end covers; each circular cutter body is provided with a shaft hole in the center, and each cutter body sleeves the cutter shaft through the corresponding shaft hole; each cutter body comprises a blade portion with the middle protruding and cutter back portions located on two sides of the blade portion, and the blade portion and the cutter back portions are of an integral structure; the bearings are arranged between the cutter bodies and the cutter shaft side by side; the end covers sleeve the cutter shaft and are respectively located on two sides of the bearings, and a sealing element is arranged between each end cover and the corresponding cutter body. The cutter bodies are of an integral structure, so that the defect that the cutter bodies of a split structure are damaged wholly easily due to the fact that cutter rings fall off, crack into blocks, break and the like is overcome; alloy teeth and/or alloy strips are further arranged on the cutter bodies, so that rock breaking efficiency is better, abrasion resistance is higher, and service life is longer. The hard-rock integral cutter is further suitable for dual-blade or multi-blade hobbing cutters.
Description
Technical field
The present invention relates to hard rock driving technology field, be specifically related to the overall cutter of a kind of hard rock.
Background technology
In shield machine and hard rock mole construction, the expense of disk cutter occupies sizable proportion in whole driving expense.The main failure forms of disk cutter has normal wear, cutter ring fracture, bearing collapse, seal failure, eccentric wear etc.Wherein cutter ring breaks in failure mode and occupies larger specific gravity.
As shown in Figure 1, disk cutter is made up of the parts such as cutter ring a11, cutter hub a12, cutter shaft a2, end cap a3, bearing a4, seal member a5, cutter ring a11 and cutter hub a12 cylindrical are that interference fit is installed, namely by adding thermal expansion, cutter ring a11 cover at one end has on the cutter hub a12 of step, the other end fixes cutter ring a11 by back-up ring a13, then installs the parts such as cutter shaft a2, bearing a4, seal member a5 at cutter hub a12 inner chamber.
In the lithostratigraphy that the quartz content that tempering property is strong is high, broken landwaste meeting erosion back-up ring a13, along with the prolongation of hobboing cutter driving time, weld seam or the back-up ring a13 of back-up ring a13 itself are worn, and cause cutter ring a11 mono-side end face do not have thrust function and come off from cutter hub a12.Further, when being subject to broken rock stratum and impacting, because cutter ring a11, cutter hub a12 are connected by interference, wherein the internal stress of cutter ring a11 is large especially, and cutter ring a11 easily produces and collapses block, fracture and losing efficacy.So the hobboing cutter of conventional structure bad adaptability under above two kinds of geological conditionss, be embodied in cutter ring a11 and come off, collapse block, fracture etc. unprovoked normal wear and the probability that lost efficacy is high.
Summary of the invention
For the defect existed in prior art, the object of the present invention is to provide the overall cutter of a kind of hard rock, its rock breaking efficiency is better, and abrasion resistance is stronger, longer service life.
For reaching above object, the technical scheme that the present invention takes is: the overall cutter of a kind of hard rock, comprising: a cutter shaft; At least one cutter hub, described cutter hub is circular, and central authorities are provided with axis hole, and described cutter hub is located on described cutter shaft by described shaft hole sleeve; Described cutter hub comprises the blade part of intermediate projections and is positioned at the knife back portion of blade part both sides, and described blade part and knife back portion are integral type structure; Pair of bearings, described bearing is located between described cutter hub and cutter shaft side by side; Two end caps, described end cap is sheathed on described cutter shaft, lays respectively at described bearing both sides, is provided with seal member between described end cap and described cutter hub.
On the basis of technique scheme, described blade part is provided with carbide button.
On the basis of technique scheme, described carbide button is Talide.
On the basis of technique scheme, multiple described carbide button is circularly and evenly distributed along described blade part outer rim.
On the basis of technique scheme, on described cutter hub and/or described end cap be provided with alloy bar.
On the basis of technique scheme, described alloy bar is whole circle seamless arrangement on described cutter hub.
On the basis of technique scheme, described alloy bar on described cutter hub in being intervally arranged.
On the basis of technique scheme, described cutter hub adopts carburizing steel to make.
On the basis of technique scheme, a described cutter hub comprises multiple blade part.
Compared with prior art, the invention has the advantages that:
The present invention adopts cutter hub integral structure, and overcoming cutter hub in prior art is split-type structural, easily because cutter ring comes off, collapses the defect that block, fracture etc. cause the damage of cutter hub entirety.Cutter hub is also provided with carbide button and/or alloy bar, and rock breaking efficiency is better, and abrasion resistance is stronger, longer service life.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Shown in Figure 2, the embodiment of the present invention provides a kind of hard rock overall cutter, comprises a cutter shaft 1; At least one cutter hub 2, cutter hub 2 is in circular, and central authorities are provided with axis hole 23, and cutter hub 2 is sheathed on cutter shaft 1 by axis hole 23; Shown in Figure 3, cutter hub 2 comprises the blade part 21 of intermediate projections and is positioned at the knife back portion 22 of blade part 21 both sides, and blade part 21 and knife back portion 22 are integral type structure; Pair of bearings 3, bearing 3 is located between cutter hub 2 and cutter shaft 1 side by side, is provided with bearing space ring 31 between two bearings 3; Two end caps 4, end cap 4 is sheathed on cutter shaft 1, lays respectively at bearing 3 both sides, is provided with seal member 5 between end cap 4 and cutter hub 2.Shown in Figure 1, in prior art, cutter hub a1 is split-type structural, by cutter ring a11, cutter hub a12 and by cutter ring a11, the back-up ring a13 be fixed on cutter hub a12 forms jointly, easily because cutter ring a11 comes off, collapses block, fracture etc. and cause cutter hub a1 entirety to damage, the present invention adopts integral structure, avoids cutter ring a11 in split-type structural and easily comes off, collapses the defect such as block, fracture.
