Description
Technical field
The utility model relates to rock tunnel(ling) machine technical field of engineering machinery, particularly relate to a kind of combined cut formula hard rock pick
Into machine knife disk and its development machine.
Background technique
The cutterhead for being equipped with broken rock cutter is the critical component of complete-section tunnel boring machine tunnel excavation.Engineer application at present
In, the panel of cutterhead is planar structure, installs the tool apron of disk cutter or is placed in inside cutter head panel or preposition in cutter head panel
Surface, by the propulsion and rotary motion of cutterhead, disk cutter is poured into and attrition crushing rock forms full face tunnel excavation.
The principle of this cutter head structure broken rock is that hobboing cutter destroys the uniaxial compressive strength of rock by the powerful thrust of cutterhead and pours into rock
Stone forces rock to form crack, forms broken block behind crack and crack perforation and the (see figure 1) that falls off.This structure cutterhead power consumption
Greatly, as the increase power consumption of rock uniaxiality strength constantly increases, and broken rock is more difficult.Therefore a kind of the hard of low-power consumption is designed
Rock development machine cutter head structure is of great significance.
Utility model content
The tensile strength of rock is much smaller than compression strength, generally only several Mpa to more than ten Mpa.The outstanding original for cutting through rock
Reason is the rock for allowing cutter cutting to have free face, this broken by destroying the tensile strength of rock come fractured rock (see figure 2)
The power consumption that rock mode needs is low in energy consumption more than extruding broken rock.The utility model proposes a kind of combined cut formula hard rock mole knives
It is big to solve existing cutterhead broken rock power consumption using squeezing broken rock and the outstanding combination broken rock mode for cutting through rock for disk and its development machine
Problem.
The technical solution of the utility model is achieved in that a kind of combined cut formula hard rock mole cutterhead, including knife
Disk, the central area of the cutter head panel are planar structure, and lateral area is part pyramid like configuration, and planar structure installs several
Disk cutter, several handles of part pyramid like configuration installation are outstanding to cut hobboing cutter.
The disk cutter includes center cutter and positive hobboing cutter, and the hobboing cutter axis of disk cutter is vertical with cutter axis, disk
Shape hobboing cutter is arranged along knife pitch tracks radius lines.
At β angle, β is acute angle for the outstanding hobboing cutter axis for cutting hobboing cutter and cutter axis, outstanding to cut hobboing cutter along knife spacing rail
Mark radius stepped arrangement.
Several equally distributed slag inlets are arranged in the outer of the cutterhead.
Each slag inlet bottom is disposed with slag-screening board.
A kind of development machine of combined cut formula hard rock mole cutterhead, the cutterhead are mounted on development machine.
The advantages of the utility model: arrangement disk cutter and the outstanding power consumption for cutting hobboing cutter combination broken rock cutterhead needs are more than independent
Arrange the low in energy consumption of disk cutter broken rock cutterhead, efficiency of breaking rock is high, and construction cost is low, more low consumption environmental protection；This kind of cutter head structure
It is particularly suitable for the hard rock mole that rock strength is high, digging diameter is big.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figs 1-4, a kind of combined cut formula hard rock mole cutterhead, including cutterhead, in the cutter head panel
Heart district domain is planar structure, and lateral area is part pyramid like configuration, and planar structure installation is several disk cutter, part pyramid like configuration peace
Fill that several handles are outstanding to cut hobboing cutter.
The disk cutter includes center cutter and positive hobboing cutter, and the hobboing cutter axis of disk cutter is vertical with cutter axis, disk
Shape hobboing cutter is arranged along knife pitch tracks radius lines.Due to the arrangement of dish type cutterhead, between adjacent dish type cutterhead only
Radial spacing h1.
At β angle, β is acute angle for the outstanding hobboing cutter axis for cutting hobboing cutter and cutter axis, outstanding to cut hobboing cutter along knife spacing rail
Mark radius stepped arrangement.Due to hanging the arrangement of cutter disc, it is adjacent it is outstanding cut existing radial spacing h2 between hobboing cutter, and have
Axial spacing h3.
Several equally distributed slag inlets are arranged in the outer of the cutterhead.
Each slag inlet bottom is disposed with slag-screening board.
A kind of development machine of combined cut formula hard rock mole cutterhead, the cutterhead are mounted on development machine.
Cutter head panel intermediate region is planar structure, and outside is part pyramid like configuration.The tunnel excavation radius of cutterhead is R, knife
Disk plane domain arrangement squeeze broken rock disk cutter, disk cutter knife spacing (hobboing cutter formed track between spacing, such as
It is Fig. 4) h1, utilizes the rock in the region disk cutter attrition crushing area radius surface R1.Cutterhead circular conical surface region arrangement is outstanding to cut
The outstanding of broken rock cuts hobboing cutter, the outstanding rock cutting hobboing cutter and being responsible in the broken region face R2.It is outstanding to cut hobboing cutter radially arrangement spacing h2, edge
Cutterhead axially arranges spacing h3, and cutter path is stepped, and (longitudinal section that the i.e. outstanding broken rock end face for cutting hobboing cutter is formed is in ladder
Shape).Cutterhead is every to cut hobboing cutter outstanding and all generate one by cutter head center to the outstanding hobboing cutter broken rock region of cutting of adjacent outer in driving
Free face 7 makes every handle is outstanding to cut that hobboing cutter is outstanding to cut through crushed rocks.And outstanding when cutting hobboing cutter arrangement, hobboing cutter axis and cutter axis (i.e. tunnel
Hole axis 8) form an angle β, and it reduces and cuts hobboing cutter cutter disk body and knife caused by the contact of hole wall rock in rock break-off process because hanging
The heel and toe wear of tool.
While cutterhead rotates, slag inlet blows rock off, brings into inside cutterhead, and import conveying equipment by slag-screening board
It transports outside hole.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
