Abstract
The invention discloses a combined down-the-hole hammer, which comprises single hammers, an annular rack, a slag return exhaust sleeve, slag discharge tubes and an input shaft. The annular rack is an annular structure, a plurality of through holes distributed uniformly are arranged on the annular rack and used for fixing the single hammers, the upper end of the input shaft is connected with a drill pipe, the lower end of the input shaft is connected with a flange on the annular rack, so that torque can be transmitted, the slag discharge tubes are placed above the annular rack, the lower end surfaces of the slag discharge tubes are connected with the upper ends of the single hammers, and the upper end surfaces of the slag discharge tubes are connected with the slag return exhaust sleeve. The combined down-the-hole hammer can be used with a cylindrical drill and the like, the area of rock required to be impacted and crushed is greatly reduced, drilling efficiency is improved, and the combined down-the-hole hammer is simpler in processing and lower in cost as compared with a single large-diameter down-the-hole hammer.
Description
Technical field
The invention belongs to down-the-hole hammer technical field, relate to a kind of ring type major diameter combination down-the-hole hammer, be used for the construction of large diameter borehole perfusion post, can with rotary drilling rig or the supporting use of heavy caliber engineering driller.
Background technology
Bored pile is a kind of advanced basic engineering construction technology, worldwide be widely used, and pneumatic down-hole hammer is widely used in bored pile construction; Be particularly useful for hard rock and competent bed; Its rate of penetration is much higher than simple rotary drilling, and existing monomer Large Diameter DTH Hammer hammer, combined type down-the-hole hammer all are primarily aimed at 800～1500mm stake hole, when stake bore dia expanded range; Rate of penetration and drilling efficiency can reduce greatly; And the rock area of impact grinding is increased, and it is complicated that processing becomes, and production efficiency is extremely low.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of combination down-the-hole hammer.
The present invention is achieved through following technical scheme.
Combination down-the-hole hammer of the present invention comprises monomer hammer, toroidal frame, anti-slag exhaust flange, scum pipe and power shaft;
---toroidal frame adopts loop configuration, on put some equally distributed through holes, be used for fixing the monomer hammer;
---the upper end of power shaft is connected with drilling rod, and the lower end is connected with flange on the toroidal frame, with transfer torque;
---scum pipe places the toroidal frame top, and the lower surface of scum pipe links to each other with monomer hammer upper end, and the upper surface links to each other with anti-slag exhaust flange.
The external stability of said anti-slag exhaust flange is connected with anti-slew gear.
Compared with prior art, the technique effect that the present invention reaches is for being used with tube brill etc., and the rock area of required impact grinding reduces greatly, has improved drilling efficiency, and than monomer Large Diameter DTH Hammer hammer, processes simplyr, and cost is lower; In addition, anti-slag exhaust flange can realize the function of anti-slag, exhaust simultaneously among the present invention.
Description of drawings
Fig. 1 is the structure chart of the embodiment of the invention;
Fig. 2 is the vertical view of the embodiment of the invention;
Among the figure: 1-monomer hammer, the 2-toroidal frame, the anti-slag stack of 3-, 4-prevents slew gear, 5-scum pipe, 6-power shaft.
The specific embodiment
Further describe technical scheme of the present invention below in conjunction with accompanying drawing, but require the scope of protection to be not limited to said.
Fig. 1 and 2 has represented the structure chart of the embodiment of the invention, and combination down-the-hole hammer of the present invention comprises monomer hammer 1, toroidal frame 2, anti-slag exhaust flange 3, scum pipe 5 and power shaft 6; Toroidal frame 2 adopts loop configuration, on put some equally distributed through holes, be used for fixing the mode that 1,6 monomer hammer 1 of monomer hammer adopts Bolt Connection, be distributed on the toroidal frame, form circulus; The upper end of power shaft 6 is connected with drilling rod, and the lower end is connected with flange on the toroidal frame 2, with transfer torque; Scum pipe 5 places toroidal frame 2 tops, and the lower surface of scum pipe 5 is hammered 1 upper end into shape with monomer and linked to each other, and the upper surface links to each other with anti-slag exhaust flange 3; Said anti-slag exhaust flange 3 external stabilities are connected with anti-slew gear 4.
Adopt the present invention to carry out the heavy caliber hard rock when creeping into; Machine power is delivered to power shaft 6 by drilling rod; Because toroidal frame 2 utilizes flange to be connected with power shaft 6, and monomer hammer 1 all is fixed on the toroidal frame 2, is center steering so input torque capable of using drives whole drill bit bottom with the power shaft.Compressed air is hammered the air inlet port on 1 via the intake interface of external high pressure sebific duct, anti-slag exhaust flange 3 into shape to monomer, gets into each monomer hammer 1, drives 6 monomers hammer 1 actions simultaneously, produces lasting impact shock effect, broken hard rock.Rock after the fragmentation, through the center slagging channel of each monomer hammer 1, the slagging channel in the anti-slag exhaust flange 3 of scum pipe 5 entering, thus landwaste is discharged the face of land.Anti-slag exhaust flange 3 outsides are fixedly connected with anti-slew gear 4, prevent its outside revolution, twine to avoid sebific duct, and anti-slag exhaust flange 3 inside are fixedly connected with power shaft 6, turn round simultaneously with power shaft 6.
