Description
Technical field
The present invention relates to the slotting drill used in colliery hydrofracturing processing top plate, is specially that hydrofracturing Orthogonal Composite is double
Sword slotting drill.
Background technology
Colliery handle top plate method in, hydrofracturing with its it is easy to operate, safe, implementation result is good the advantages that mesh
It is preceding to be widely popularized use.The realization of hydrofracturing reuses slotting drill and carries out grooving by the drilling into rock, and
Afterwards by high-pressure water injection device sealing of hole water filling after, pressure realizes fracturing when reaching rock failure mechanism of rock intensity level.Existing slotting drill
Device only equipped with a pair of of grooving cutlery, can only cut to form a ring shake, and during rock is cut occur and cut
Situations such as groove cutlery is broken, influences the formation of joint-cutting, so as to limit the using effect of hydrofracturing to a certain extent.
The content of the invention
The present invention solves the problems, such as that existing slotting drill only has a pair of of grooving cutlery and grooving cutlery easy fracture, there is provided a kind of
Hydrofracturing Orthogonal Composite twolip slotting drill.
The present invention adopts the following technical scheme that realization：Hydrofracturing Orthogonal Composite twolip slotting drill, including drill bit
Overcoat, one end stretch into the main shaft of drill bit overcoat, put on outside drill bit be provided with vertically two positions it is opposite first go out cutter groove, along axis
To be also provided with two positions it is opposite second go out cutter groove, first, which goes out cutter groove and second, goes out cutter groove and is distributed along drill bit overcoat axially spaced-apart
And locus is mutually orthogonal；Put on outside drill bit and be provided with the first opposite pin slide card slot of two positions vertically, the first pin
Axis slip draw-in groove goes out that cutter groove position is orthogonal with first, is put on outside drill bit and is provided with the second opposite pin slide of two positions vertically
Card slot, it is orthogonal that the second pin slide card slot with second goes out cutter groove position；Main shaft, which is stretched on the part of drill bit overcoat, to be provided with along main shaft
The the first blade groove and the second blade groove that axially spaced-apart is distributed and locus is orthogonal；There are two the first groovings in first blade groove
Cutlery, the first axis pin pass perpendicularly through the first blade groove, two the first grooving cutleries tail end and make it（First axis pin）Both ends card
In in the first pin slide card slot；There are two the second grooving cutleries in second blade groove, the second axis pin passes perpendicularly through the second blade
Groove, two the second grooving cutleries tail end and make it（Second axis pin）Both ends are stuck in the second pin slide card slot；When main shaft by
Drive along drill bit overcoat move axially when, the first axis pin, the second axis pin are respectively in the first pin slide card slot, the second pin slide card
Slide in groove, meanwhile, the first axis pin, the second axis pin drive two the first grooving cutleries, two the second grooving cutleries from the respectively
One go out cutter groove, second go out cutter groove stretch out or withdraw drill bit overcoat；Main shaft is axially hollow structure, and hollow space forms water guide and leads to
Road, the other end of main shaft are connected with being connected one end of overcoat, are cased with being compressed between drill bit overcoat and connection overcoat on main shaft
Spring.
In use, the other end of connection overcoat may be coupled on the drill steel of ordi-nary drilling machine, connection mode connects for spiral shell button.
During into pricker, under the action of the spring, two groups of grooving cutleries are in contraction state, are easy to deeply.During grooving, which is boring
The lower rotation of machine driving, while its main shaft is moved forwardly under the effect of drilling machine drill steel so that two the first grooving cutleries, two
Second grooving cutlery from first go out cutter groove, second go out cutter groove stretch out drill bit overcoat, so as to complete the cutting of ring shake.Move back pricker
When, under the collective effect of the wall of a borehole and spring, two groups of grooving cutleries are forced inwardly contraction, so as to reach the mesh for easily moving back pricker
's.
Slotting drill of the present invention, can on the wall of a borehole accomplished fluently due to the use of two groups of orthogonal grooving cutleries
Two V row grooves are cut out to dig at the same time, compared with common slotting drill, efficiency is doubled；Can after two groups of blade cuttings
Two groups of ring shakes are formed, not only increase stability, the reliability of grooving blade joint-cutting, while ensure that the broken of hydrofracturing
Bad scope and radius, have haveed the function that to weaken coal petrography, have ensured and improve the effect and intensity of hydrofracturing, are to realize orientation
Effective rock drilling equipment of hydrofracturing；The orthogonal thereto orientation arrangement of two groups of grooving cutleries, rationally make use of limited space；Structure letter
It is single, easily fabricated, of low cost, easy to use, reliable.
