Description
Technical field
The present invention relates to tunnel piercing cutterheads, particularly relate to a kind of hard rock cutterhead and the cantilever excavator including the cutterhead.
Background technique
With advancing for driving technology, in the construction of ground consisting of hard rock, do not require nothing more than securely and reliably, while driving is imitated
The requirement of rate is also being continuously improved, and using TBM equipment, then cost is excessively high in ground consisting of hard rock, the safety if using explosion rock is bored
Property it is lower, drivage efficiency is lower if using continuous miner or the anchor combined unit of pick, and the secure, cost as a kind of safety
Lower, the higher cantilever excavator of drivage efficiency will be greatly developed.
And at present the heading end of cantilever excavator be mainly the cutterhead of two symmetrical hemisphericals or drum-shape (such as
Entitled " a kind of horizontal shaft type tunneling machine cutting simulated experiment platform ", application No. is 201811105636.7 applications for a patent for invention),
Either single cone or tapered cylindrical shape cutterhead (such as entitled " compound cantilever excavator ", application No. is
201210207419.5 application for a patent for invention), serrated knife is to arrange according to a fixed spacing along helix on cutterhead, in hard rock
Stratum is compared with using TBM cutterhead, and drivage efficiency is lower.Therefore to a kind of cantilever excavator driving head of energy high efficient driving
It pursues and is constantly promoted.
Summary of the invention
The present invention proposes a kind of hard rock cutterhead and the cantilever excavator including the cutterhead, solves existing cantilever pick at present
The problem slow in ground consisting of hard rock drivage efficiency into machine.
The technical scheme of the present invention is realized as follows: a kind of hard rock cutterhead, the cutterhead main structure including taper, cutterhead master
Structure includes head, spoke and flange, and head is connect with spoke, spoke and flanged joint, and head and spoke are equipped with detachably
Cutter.
The cutter is serrated knife.
The cutter is hobboing cutter.
The cutterhead main structure is equipped with cutter groove, and end cap is detachably secured in cutter groove, the upper surface of end cap and cutterhead
The upper surface of main structure is concordant, and hobboing cutter is equipped in end cap.
The end cap is bolted in cutter groove.
The head is equipped with flexible center tool apron, and center tool apron is equipped with dismountable cutter, center tool apron with
Oil cylinder connection, oil cylinder and flanged joint.
The spoke is arranged in cross.
The spoke is arranged in * shape.
The spoke is arranged in M shape.
A kind of cantilever excavator including above-mentioned hard rock cutterhead.
Advantages of the present invention:
1. cutterhead is evenly distributed using spoke and taper symmetrical structure, cutter, cutter head structure is more uniformly stressed, and cutterhead, which is resisted, to be become
Shape and the ability of destruction are stronger, and preferable intensity and toughness makes cutterhead that can bear the pick such as high thrust, high revolving speed in cantilever excavator
Into operating condition.
2. cutterhead main structure is welded using whole plate fabrication design or steel plate, integral strength rigidity is more preferable, reduces knife
Deformation in disk tunneling process provides structure basis for the reliable installation of cutter.
3. cutterhead removable cutting tool is seated the installation form of tool apron mounting surface using end cap, therefore cutter bears excavation face
Reaction force is directly passed to tool apron by cutter end cap, then passes to cutterhead main structure by tool apron, and cutter fixing bolt does not provide
The support force of cutter, only plays fixed function, and the higher Cutting tool installation manner mode of reliability and reasonable cutter arrangement are able to ascend
The efficiency of breaking rock of cutterhead driving.
4. cutter head center hobboing cutter can be retracted when cutterhead swings and cuts, central hob can be effectively avoided to occur inclined
The abnormal damages problem such as mill, tipping.
5. the equipment can excavate weak soil, can also dig hard rock by the exchange installation of the cutters such as hobboing cutter and serrated knife.Hard rock
When stratum is tunneled by hobboing cutter positive pressure broken rock and it is outstanding cut through the Multiple Combination of rock in the way of, excavation face rock can efficiently be broken
Rock；Soil stabilization stratum can be changed to serrated knife, efficiently be excavated using serrated knife to excavation face.
6. cutterhead is bobbed and woven by the cantilever of cantilever excavator, round and section, phase can be excavated
To full face tunnel boring machine, whole set equipment is at low cost, and mobility is good, relative to current cutting hair style development machine head, excavates efficiency
It is high.
