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-hole hammer technical field, relate to a kind of ring type major diameter combination down-hole hammer, for the construction of large diameter borehole perfusion post, can support the use with rotary drilling rig or Large Diameter Engineering rig.
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, existing monomer Major diameter downhole hammer, combined down-hole hammer are all mainly for 800～1500mm stake hole, when stake bore dia expanded range, rate of penetration and drilling efficiency can reduce greatly, and can make the rock area of impact grinding increase, 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-hole hammer.
The present invention is achieved by following technical solution.
Combination down-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, above puts some equally distributed through holes, for securing unit, hammers into shape;
---the upper end of power shaft is connected with drilling rod, and lower end is connected with the flange on toroidal frame, with transmitting torque;
---scum pipe is placed in toroidal frame top, and the lower surface of scum pipe is connected with monomer hammer upper end, and upper surface is connected with anti-slag exhaust flange;
---the intake interface of described anti-slag exhaust flange is connected with the air inlet port on monomer hammer, and the slagging channel of anti-slag exhaust flange is connected with scum pipe.
The external stability of described anti-slag exhaust flange is connected with anti-rotation mechanism.
Compared with prior art, the technique effect that the present invention reaches is for being used in conjunction with cylinder brill etc., and the rock area of required impact grinding reduces greatly, has improved drilling efficiency, and compared with monomer Major diameter downhole hammer, processes simplyr, and cost is lower; In addition, in the present invention, anti-slag exhaust flange can realize the function of anti-slag, exhaust simultaneously.
Accompanying drawing explanation
Fig. 1 is the structure chart of the embodiment of the present invention;
Fig. 2 is the top view of the embodiment of the present invention;
In figure: 1-monomer hammer, 2-toroidal frame, the anti-slag exhaust flange of 3-, the anti-rotation mechanism of 4-, 5-scum pipe, 6-power shaft.
The specific embodiment
Below in conjunction with accompanying drawing, further describe technical scheme of the present invention, but described in claimed scope is not limited to.
Fig. 1 and 2 has represented the structure chart of the embodiment of the present invention, and combination down-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, above puts some equally distributed through holes, adopts the mode of Bolt Connection for 1,6 monomer hammer 1 of securing unit hammer, is distributed on toroidal frame, forms circulus; The upper end of power shaft 6 is connected with drilling rod, and lower end is connected with the flange on toroidal frame 2, with transmitting torque; Scum pipe 5 is placed in toroidal frame 2 tops, and the lower surface of scum pipe 5 is hammered 1 upper end into shape with monomer and is connected, and upper surface is connected with anti-slag exhaust flange 3; Described anti-slag exhaust flange 3 external stabilities are connected with anti-rotation mechanism 4.
Adopt the present invention to carry out heavy caliber hard rock while 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 is all fixed on toroidal frame 2, therefore can utilize input torque to drive whole drill bit bottom to turn round centered by power shaft.Compressed air, via the intake interface of external high pressure sebific duct, anti-slag exhaust flange 3, is hammered the air inlet port on 1 into shape to monomer, enters each monomer hammer 1, drives 6 monomers hammer 1 actions simultaneously, produces lasting impact shock effect, breaking hard rock.Rock after fragmentation, the center slagging channel by each monomer hammer 1, enters the slagging channel in anti-slag exhaust flange 3 through scum pipe 5, thereby landwaste is discharged to earth's surface.Anti-slag exhaust flange 3 is outside to be fixedly connected with anti-rotation mechanism 4, prevents its outside revolution, and to avoid sebific duct to be wound around, anti-slag exhaust flange 3 is inner to be fixedly connected with power shaft 6, turns round with power shaft 6 simultaneously.
