Head.
Background technology
With urban construction, the expansion of Urbanization Construction, infrastructure, requirement of the engineering construction to pile foundation is increasingly
It is more.Pile foundation develops to the diameter of deeper depth, bigger, and geological conditions is increasingly complex, formation hardness, the rock encountered
Property variation bigger.There are many defects for traditional drilling coring device and method, do not adapt to the development need of pile foundation.
1. impact drill.Due to price is low, using simple, easy-operating advantage, at home use it is more.But its work is imitated
Rate is low, and speed of fulfiling hole is very slow.
2. churning driven.At present the country large-engineering construction be mostly used this equipment, churning driven drilling when frequently with method：1. short
Auger pick breaking rock, then puts on drilling tool, gains rotating bucket and pulls disintegrating slag out, then is crept into using drilling tool；Around 2. cylinder bores
Edge pick crushes rock hard grind, and then by twisting off coring energetically, the poor and controllable difficulty of coring effect is big；3. rock bit is cut entirely
Face breaking rock, then bit change pulls disintegrating slag out or slush pump slurry-sucking is replaced；4. cylinder sets rock bit, breaking rock around boring
Coring.Churning driven and corresponding method power consumption in hard-rock boring are big, efficiency is low while of high cost, acquisition price is high.
3. down-hole hammer.The equipment mine is usually used in boring and is blown out eye using more.With the demand in terms of stake work, down-hole hammer
Gradually developed by aperture radial direction major diameter, but the defect of air consumption constrains the development of major diameter.
In view of defect existing for traditional drilling coring device, the present inventor based on for many years practical experience and profession know
Know, and coordinate the application of scientific principle, to found a kind of hard rock coring bit, current pile foundation engineering can be met
It needs.

Specific implementation mode
It is of the invention to reach the technological means and effect that predetermined goal of the invention is taken further to illustrate, below in conjunction with
Attached drawing and preferred embodiment, to propose according to the present invention a kind of its specific implementation mode of hard rock coring bit, structure, feature and
Its effect is described in detail as after.
It please refers to Fig.1 and Fig. 2, a kind of hard rock coring bit of the present invention, including cylinder 1, coring device 2, under the cylinder 1
End is installed on several the first drill bits 3, and each first drill bit 3 is both provided with independent first driving means 4；The coring device 2
Across cylinder 1 and it is fixed in the upper end of cylinder 1, lower end stretches out in cylinder 1 and is less than aforementioned first drill bit 3.
Preferably, first drill bit 3 is provided with two or more, particular number can be according to diameter, rate of penetration
Demand determines.The first driving means 4 can be used hydraulic-driven, air pressure driving or Mechanical Driven, but the present invention is not limited to
This.Each first drill bit 3 can revolve round the sun under the drive of cylinder 1, can also be under the driving of independent first driving means 4
Rotation is carried out, to constantly be impacted, be crushed to hard rock, i.e., cylinder 1 is revolution, and each first drill bit 3 also can rotation.
Preferably, referring to Fig. 3, the coring device 2 is welded on the upper end of cylinder 1, lower end is installed on the second drill bit
5, it can not also install the second drill bit 5.2 one side of coring device ensure that the verticality of drilling, on the other hand creep into oblique rock
When play positioning action.
Preferably, 2 upper end of the coring device is provided with attachment device, it can be by the hard rock of the present invention by the attachment device
Coring device is connected from different drilling machines, to carry out operation.
Preferably, 2 lower part of the coring device is installed on several partition members 21, the partition member 21 is located at cylinder
In 1.After reaching predetermined drilling depth, each partition member 21 is pushed outwardly under the driving of the second driving device 22, will be in cylinder 1
Stone and the stone of lower section separate, so that stone level is cut to several piece, be then extruded in cylinder 1, coring device 2 and point
It cuts the stone between component 21 to be suggested to ground, each partition member 21 is under the reverse drive of the second driving device 22 at this time
It is retracted to the inside of coring device 2, stone is fallen in specified region.Specifically, hydraulic pressure drive can be used in the driving device 22
Dynamic, air pressure driving or Mechanical Driven, however, the present invention is not limited thereto.
A kind of workflow of hard rock coring bit of the present invention is：The drill bit of the present invention is connect with drilling machine first, then
Start drilling machine.The coring device 2 of positioning enters rock in advance than the first drill bit 3 of surrounding, and then the first drill bit 3 reenters rock, first
Rapidly hard rock is impacted under the driving of driving device 4, is crushed.After getting into predetermined drilling depth, each partition member 21 exists
It is pushed outwardly under the driving of second driving device 22, the stone of stone and lower section in cylinder 1 is separated, stone is made to be cut off
For several piece, then supports the stone in circular cylinder 1 and be suggested to ground, each partition member 21 is in the second driving dress at this time
The inside that coring device 2 is retracted under 22 reverse drive is set, stone is fallen in specified region.Then drill bit is put down again,
Continue drilling operation.
A kind of hard rock coring bit of the present invention overcomes conventional impact and bores inefficiency, and traditional churning driven is not suitable for firmly
Rock, traditional down-hole hammer are limited by air consumption and cannot be not required to crush stone whole hard grind using the defect of major diameter, be also not required to
Coring is carried out by very big torque, it is only necessary to by improved structure by stone segmentation and monoblock taking-up, improve work effect
Rate accelerates project progress.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the scope of the invention, for this hair
