Abstract
The invention provides a pile-forming rock-entering drilling tool system of a rotary drilling rig. The system comprises a chambering sleeve and a casing pipe. Hard alloy is embedded into the front end of the chambering sleeve to serve as a chambering head, the chambering sleeve is installed on a hammerhead of a pneumatic hammer through the casing pipe, the rear end of the chambering sleeve is connected with the front end of the casing pipe through a key groove, and the rear end of the sleeve is connected with the hammerhead through a key groove. According to the device, impact force generated by a down-the-hole hammer directly acts on rock for impact crushing through the casing pipe and the chambering sleeve, the problems that the rotary drilling rig difficultly enters the rock and is low in construction efficiency and high in cost, and pile hole quality is difficult to guarantee are solved, and the rotary drilling rig will be further rapidly developed in the field of pile foundations.
Description
Technical field
The present invention relates to a kind of rotary drilling rig pile and enter rock drilling system.
Background technology
Entering rock drilling system and be installed in the front end of drilling machine drilling rod, rear end is passed through lateral pin and enters rock drilling system
Connect, play transmission moment of torsion, the pivotal role of axial compression transmission, be the important composition part into rock drilling tool, and
That existing rotary drilling rig is primarily present is difficult into rock, efficiency of construction is slow, cost is high, stake holes difficult quality guarantee etc.
Problem, main reason is that rotary drilling rig is to connect drilling bucket by drilling rod, and drilling bucket front end is equipped with pick, through boring
Bar transmission axial pressure and revolution torsion are to drilling bucket so that drilling bucket pick carries out friction static pressure and crushes rock, this
It is slow that sample not only enters rock speed, and cost is high, and big in rotary shear power at the bottom of hole, the perpendicularity in hole is difficult to ensure that, and
And the degree of depth can not be carried out enter rock.
Summary of the invention
The present invention is directed to the deficiencies in the prior art and provide one both improve into rock efficiency, reduce be constructed into
This, can ensure that again a kind of rotary drilling rig pile of pile quality enters rock drilling system.
The present invention adopts the following technical scheme that realization: a kind of rotary drilling rig pile enters rock drilling system, including expanding
Borehole jack and sleeve pipe, the front end of described reaming set is inlaid with hard alloy as counter-bore head, and described reaming set passes through
Sleeve pipe is arranged on the tup of beche.
The rear end of described reaming set is connected with the front end of sleeve pipe by keyway, described sleeve pipe rear end pass through keyway and
Tup connects.
Being welded with anti-sediment set at the maximum cylindrical of described beche, the rear end of described beche is set with sheath,
The front end of described sheath is arranged in anti-sediment set, and described sheath is matched in clearance, institute with anti-sediment set
State the height of anti-sediment set make beche in maximum magnitude during action sheath and anti-sediment set without departing from.
The rear end of described beche is connected with rotary drilling rig by adapter coupling.
Described reaming put inside and outside on be all inlaid with hard alloy.
Owing to using said structure, the present invention is arranged on the tup of pneumatic beche, is directly produced by tup
Impulsive force pass to counter-bore head through sleeve pipe and reaming set again, the hard alloy of counter-bore head directly acts on rock and enters
Row impact grinding, so makes fast into rock speed and hole perpendicularity high, and crag is uniform, and this device passes through
The sheath installed after beche, thus sediment during preventing rock enters in tup, and anti-sediment set with
The cooperation of sheath ensures on the premise of not affecting tup action, it is ensured that maximum protection effect, it is interior that reaming is overlapped
Outer both sides are all inlaid with hard alloy, thus improve the effect into rock, and in sum, this device is by down-hole hammer
Generation impulsive force acts directly on through sleeve pipe and reaming set and carries out impact grinding on rock, solves rotary drilling rig
Enter the problems such as rock difficult, efficiency of construction is slow, cost is high, stake holes difficult quality guarantee so that pile foundation field is revolved
Dig rig will develop rapidly further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of reaming of the present invention set.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
As it is shown in figure 1, a kind of rotary drilling rig pile enters rock drilling system, including reaming set 1 and sleeve pipe 2,
The front end of described reaming set 1 is inlaid with hard alloy 11 as counter-bore head, inside and outside two on described reaming set 1
All being inlaid with hard alloy 11 on side, described reaming set 1 is arranged on the tup 3 of beche 6 by sleeve pipe.
The rear end of described reaming set 1 is connected with the front end of sleeve pipe 2 by keyway, and keyway is passed through in described sleeve pipe 2 rear end
It is connected with tup 3.Anti-sediment set 4 it is welded with at the maximum cylindrical of described beche 6, described beche 6
Rear end is set with sheath 5, and the front end of described sheath 5 is arranged in anti-sediment set 4, and described sheath 5 with
Anti-sediment set 4 is matched in clearance, and the height of described anti-sediment set 4 makes beche action in maximum magnitude
Time sheath and anti-sediment set without departing from.The rear end of described beche is connected with rotary drilling rig by adapter coupling 7,
In this example, beche 6 is pneumatic beche.
The length of described reaming set manufactures according to the power transmission intensity such as bore diameter and the degree of depth, the length of sleeve pipe
Manufacture according to entering the rock degree of depth.
Job site rotary drilling rig and connection procedure of the present invention: drilling machine drilling rod top is connected with air compressor machine,
The front end of rotary drilling rig is connected with the rear end of beche by adapter coupling 7.
Work progress: rotary digging drill power head revolution produces moment of torsion and passes to drilling system of the present invention by drilling rod,
Air pressure is delivered to beche 6 through drilling rod through high-pressure air hose by air compressor again, and beche piston is transported up and down
The raw ballistic work of movable property, acts on tup 3, and 3 impulsive forces of tup pass to reaming set 1, reaming through sleeve pipe 2
Overlap 1 impulsive force to be distributed on the counter-bore head that hard alloy 11 is formed rock is crushed, then beche
6 air pressure discharged are discharged at the bottom of hole clear up broken rock slag through tup endoporus and casing tube internal hole, it is ensured that hole
The cleannes at the end, reduce hard alloy and repeat to crush to fractured rock, accelerate rock equally
Broken progress, serves vital effect to improved efficiency.
