Technical field
This utility model relates to engineering exploration, Geotechnical Engineering test, drilling engineering one vertically the earth's core boring inverted vertical hole leads
To device.
Background technology
In the boring procedure such as engineering investigation probing, Geotechnical Engineering foundation pile drilling core examination, drilling engineering, general requirement
Boring direction is vertical in the earth's core, it is therefore an objective to measure that stake is long, sediment of the hole bottom thickness, equipment peace in holding force rock and soil properties, wellhole at the bottom of stake
Put to projected depth.Because being affected by factors such as earth formation, drilling operation technology, drilling equipment conditions, boring often glances off,
Bending, it is difficult to reach predetermined hole depth, when carrying out Geotechnical Engineering foundation pile drilling core examination, often result in boring and do not reach and should have
The degree of depth deflect away from outside stake, cause pile bottom sediment thickness, bearing course at pile end characteristic to pass judgment on, boring can not meet setting want
Asking, prospecting, pile detection quality of achievement and work efficiency are affected.
Utility model content
The purpose of this utility model is the deficiency existed for prior art, it is provided that one can vertically the earth's core, Ke Yiyin
Lead drill bit, the drilling guide device that falls to hang down do not make boring glance off, bending.
The purpose of this utility model is the deficiency existed for prior art, it is provided that following technical scheme:
A kind of drilling guide device that hangs down, including guiding liptinite, drilling rod and joint；Described guiding stablizes internal setting
There is through hole；The length of described drilling rod is more than the length of guiding liptinite, and described drilling rod is fixed on and guides the logical of liptinite
In hole, described joint is detachably arranged in the upper and lower side of drilling rod.
Further, the described liptinite that guides is the cylinder that round steel material makes；Guide liptinite self to have relatively
Big weight, guides drill bit drilling direction, increases stability.
Further, the outer surface of described guiding liptinite carrys out good fortune helix groove at least provided with two dextrorotation；?
Guiding liptinite during boring to rotate together with drill bit, in helical groove, flushing liquor is under the effect of rotary centrifugal force, recessed along spiral
At the bottom of bulky grain rock dust tap at the bottom of groove rapid increase, beneficially hole, increase vertical drilling pressure forward simultaneously.
Further, in order to increase the wearability guiding liptinite, increase its service life, described guiding liptinite 1
Upper end is also inlaid with high-abrasive material.
Further, in order to increase the rational position distribution of service life and the high-abrasive material guiding liptinite, described
The high-abrasive material guiding liptinite upper end is provided with at eight altogether, and arranges the most symmetrically.
Further, described drilling rod is welded in the through hole guiding liptinite.
Further, described drilling rod is removably connected by screw thread with joint.
Further, the diameter of described guiding liptinite is less than outside diameter 1-2mm, and the convenient liptinite that guides puts in brill
Bit is followed in Tou.
Beneficial effect: this utility model has the advantage that compared with traditional design
(1) inverted vertical hole guider of the present utility model, simple in construction, cost of manufacture is low, is had relatively greatly certainly by setting
The guiding liptinite of weight, relies on self gravitation to pressurize hole subdrilling head, automatically revises boring towards direction, the earth's core during boring during boring
Creeping into, when preventing from being pressurizeed by aperture, drill pipe buckling causes hole scattering, bending, makes the straight rule of borehole wall；
(2) outer surface guiding liptinite in this utility model is additionally provided with helix groove, can by helix groove
With at the bottom of bulky grain rock dust tap that hole subdrilling is gone out, it is also possible to increase vertical drilling pressure the most forward；And guide liptinite
On be also evenly arranged high-abrasive material, by arrange high-abrasive material can increase guide liptinite service life；
(3) guiding liptinite, drilling rod, joint and drill bit in this utility model all use screw thread wildcard, can bore according to stratum
Entrance pressure power needs, and the connection quantity of of the present utility model inverted vertical hole guider is quickly increased or decreased, reduces other drillers
Tool is equipped with.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, being further elucidated with this utility model, the present embodiment is with this utility model
Implement under premised on technical scheme, it should be understood that these embodiments are merely to illustrate this utility model rather than limit this reality
By novel scope.
As it is shown in figure 1, a kind of drilling guide device that hangs down, including guiding liptinite 1, drilling rod 2 and joint 3；Described leads
It is provided with through hole in liptinite 1；The length of described drilling rod 2 is more than the length of guiding liptinite 1, and described drilling rod 2 is admittedly
Being scheduled in the through hole guiding liptinite 1, described joint 3 is detachably arranged in the upper and lower side of drilling rod 2.
Guide the cylinder that liptinite 1 makes for round steel material；Guide liptinite 1 and self there is bigger weight, guide
Drill bit drilling direction, increases stability.
The outer surface guiding liptinite 1 carrys out good fortune helix groove 4 at least provided with two dextrorotation；The guiding steady when boring
Determining body 1 to rotate together with drill bit, in helical groove 4, flushing liquor is under the effect of rotary centrifugal force, along helical groove rapid increase,
Be conducive at the bottom of bulky grain rock dust tap at the bottom of hole, increase vertical drilling pressure forward simultaneously.
In order to increase the wearability guiding liptinite 1, increasing its service life, the upper end of described guiding liptinite 1 is also inlayed
It is embedded with high-abrasive material 5；In order to increase the rational position distribution guiding service life of liptinite 1 and high-abrasive material, described in lead
High-abrasive material 5 to liptinite 1 upper end is provided with at eight altogether, and arranges the most symmetrically.
Drilling rod 2 is welded on face in the through hole guiding liptinite 1, and drilling rod 2 is removably connected by screw thread with joint 3；Lead
To the diameter of liptinite 1 less than outside diameter 1-2mm, convenient guiding liptinite puts in follows bit in drill bit.
Inverted vertical hole guider of the present utility model, holes for engineering investigation probing, foundation pile drilling core checking, drilling well etc.,
Have simple in construction, low cost of manufacture, drilling and forming hole hole when bed rock powder are prone to discharge, vertical the earth's core drilling guide is to dependable performance etc.
Advantage.
Guiding liptinite is that round steel material makes, and self has weight relatively big, is connected to particle size drilling tool top at the bottom of hole, during boring
Rely on self gravitation that hole subdrilling head is pressurizeed, automatically revise during boring and hole towards direction, the earth's core, bore when preventing from being pressurizeed by aperture
Rod bending causes hole scattering.
Guide liptinite diameter to inlay wear-resisting cutting material less than outside diameter 1～2mm, guiding liptinite upper end, can protect
The working life of card liptinite.
Guiding is stablized external table and is machined with dextrorotation and carrys out good fortune helix groove, guides liptinite and together revolve with drilling rod during boring
Turning, in helical groove, flushing liquor is under the effect of rotary centrifugal force, along bulky grain rock at the bottom of helical groove rapid increase, beneficially hole
At the bottom of powder tap, increase vertical drilling pressure forward simultaneously.
And this utility model is all screw thread wildcard connects installation, quickly can increase according to stratum drilling pressure needs
Or the connection quantity of minimizing single unit system, reduce the outfit of other boring tools.
