Description
Technical field
The utility model relates to shield machine technical fields, particularly relate to a kind of axial, lateral two-way excavation cutterhead.
Background technique
Shield machine cuts the front soil body by cutterhead, cutter in constructing tunnel, the adaptation journey of cutter and the soil body
It spends most important.The different soil bodys needs to excavate it with different cutterhead and tooling setup, can just shield machine be made to complete
Quick tunneling construction.
The structure of existing cutterhead mainly has panel type and spoke type two major classes type.But whether being panel type or spoke
Formula, the TBM cutterhead excavated at present applied to hard rock tunnel can only be realized to be promoted along tunnel axis direction, and excavated section is round disconnected
Face.It is excavated without can be carried out radial excavate with shaped face.In order to realize the excavation of anisotropic section, it is desirable that excavate cutterhead and have axis
The function of being excavated to, lateral both direction.Therefore, two-way excavation cutterhead becomes research emphasis.
Utility model content
For the deficiency in above-mentioned background technique, the utility model proposes a kind of axial, lateral two-way excavation cutterheads, solve
In the prior art TBM cutterhead can only realize it is axial promote, the problem that excavated section is limited.
The technical solution of the utility model is achieved in that a kind of axial, lateral two-way excavation cutterhead, including cutterhead sheet
Body, the front end face of cutterhead body are equipped with front knife, and the outer edge of cutterhead body front end face is equipped with side hobboing cutter, cutterhead body
Excircle is equipped with side knife and slag inlet.
The side hobboing cutter is inclined outwardly setting, tilt angle theta=30 ° ~ 60 ° of side hobboing cutter.
The height that the side hobboing cutter stretches out cutterhead body is greater than the height that front knife stretches out cutterhead body；Side hobboing cutter stretches out knife
The width of disk ontology is greater than the width that side knife stretches out cutterhead body.
Arc transition area is equipped between the front end face of the cutterhead body and the excircle of cutterhead body, hobboing cutter setting in side exists
At arc transition area.
The excircle of the cutterhead body is equipped at least two slag inlets, is equipped with one group of side between two neighboring slag inlet
Face knife.
One group of side knife includes several side knives, and side knife spiral is arranged on the excircle of cutterhead body, side
The cutting direction of face knife is vertical with cutterhead body direction of advance.
The utility model carries out axial excavation by front knife, carries out radial excavation by side knife, by side hobboing cutter into
Row antarafacial excavates.Cutterhead is when forward horizontal promotes under the action of driving device, the front knife of cutterhead and the side in arc transition area
Hobboing cutter work, the outline excavation of side hobboing cutter exceed the excavation face of side knife, and side cutter does not work, thus protect side knife not by
Horizontal force guarantees that side knife is not damaged when level promotes；When cutterhead works under the action of driving device to diameter, cutterhead side
Face knife and the work of side hobboing cutter, front knife do not work, and side hobboing cutter excavation face exceeds front knife outline excavation, thus make front knife not by
Power guarantees that cutterhead front knife is not damaged.The utility model can realize that two-way, antarafacial excavates, and front knife and side knife can carry out
Interval works alternatively, and changes digging mode, improves cutter life, is a big innovation of tunnel excavation.
Detailed description of the invention
It, below will be to attached drawing needed in embodiment description in order to illustrate more clearly of the utility model embodiment
It is briefly described, it should be apparent that, the drawings in the following description are merely some embodiments of the present invention, for ability
For the those of ordinary skill of domain, without creative efforts, it can also be obtained according to these attached drawings other attached
Figure.
Fig. 1 is the utility model entirety schematic side view.
Fig. 2 is the utility model side hobboing cutter scheme of installation.
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. 1-2, embodiment 1, a kind of axial, lateral two-way excavation cutterhead, including cutterhead body 1, cutterhead body 1
Front end face be equipped with several front knives 2, front knife 2 can be used hobboing cutter, and the blade of front knife ends direction and cutterhead sheet
The central axial direction of body is identical, excavates for axis.The outer edge of 1 front end face of cutterhead body is equipped with several side hobboing cutters 3,
Side hobboing cutter 3 can be used for axial excavate and excavate with radial.The excircle of cutterhead body 1 is equipped with several side knives 4 and several
Slag inlet 5.Side knife 4 is excavated for radial, and the dregs under front knife 2, side hobboing cutter 3 and side knife 4 excavate enters through slag inlet 5
Cutterhead body transports after with the upper dregs conveying mechanism of set after spy.
Further, the side hobboing cutter 3 is inclined outwardly setting, tilt angle theta=30 ° of side hobboing cutter 3 or 60 °, is obliquely installed
Side hobboing cutter improves excavation area, can be used for antarafacial excavation.The height that the side hobboing cutter 3 stretches out cutterhead body 1 is greater than front knife 2
Stretch out the height of cutterhead body 1；The width that side hobboing cutter 3 stretches out cutterhead body 1 is greater than the width that side knife 4 stretches out cutterhead body 1.
Cutterhead is under the action of driving device when forward horizontal propulsion, and the front knife of cutterhead and the side hobboing cutter in arc transition area work, side
The outline excavation of hobboing cutter exceeds the excavation face of side knife, and side cutter does not work, so that side knife be protected by horizontal force, not guarantee
Side knife is not damaged when level promotes；When cutterhead works under the action of driving device to diameter, cutterhead side knife and side rolling
Knife work, front knife do not work, and side hobboing cutter excavation face exceeds front knife outline excavation, so that front knife be made not stress, guarantee knife
Disk front knife is not damaged
Embodiment 2, a kind of axial, lateral two-way excavation cutterhead, the side hobboing cutter 3 are inclined outwardly setting, and side hobboing cutter 3 inclines
Rake angle θ=45 °.Arc transition area, side hobboing cutter are equipped between the front end face of the cutterhead body 1 and the excircle of cutterhead body 1
3 are arranged at arc transition area.The width in arc transition area is greater than the diameter of cutterhead body excircle, arc transition area Xiang Qianshen
The front end face of cutterhead body out makes the outline excavation of side hobboing cutter be respectively greater than the outline excavation of front knife and side knife, for pair
The protection of front knife and side knife.
Further, the excircle of the cutterhead body 1 is equipped at least two slag inlets 5, can be equidistantly positioned four, phase
