Description
Technical field
The present invention relates to a kind of rotary pile-digging machine, specifically relate to a kind of both can broken rock core bottom rotary pile-digging machine hole, the water filling of counterboring petrosal foramen can become the multi-functional rock of wearing of tooth and bore again.
Background technology
The various model rotary pile-digging machines of current use, once run into rock stratum in borehole process, it is all very difficult that rock worn by existing various drilling tool, pineapple head drilling tool reaches the rock stratum of about 100mpa to uniaxial compressive strength, the rock degree of depth about 1 meter within 6-8 hour, can be bored, cartridge type core drill is configured on high-power rotary pile-digging machine and uses, about 2 hours can the trepan degree of depth about 1 meter, but its removal of core is but very difficult, usually also need to bore to grab with pick bucket again after broken rock core separately to drag for slag pore-forming, it is in the process of trepan hole wall, the water in stake holes is prevented to flow to brill tooth tip portion in time because boring the stone end dug in cannelure, bore tooth and can not get timely cooling, after brill tooth is heated, its intensity sharply declines, bore tooth consumption very big, the general trepan degree of depth about 1 meter, generally must change a sub warhead and bore tooth, at the bottom of the hole using Xiangyang Chang Kan intelligent machine Co., Ltd to produce, hydraulic pressure high-frequency percussion is bored, although very fast broken rock core can be realized, but when its vibrator works, the scar that its outer casing (spline casing) is difficult to be located with it forms stable frictional force, cause outer casing reliably can not stop the outer collar of swivel joint with its heart portion with turning, often there is oil transportation in result, the pipeline of water or winding telescopic drill rod, rupture in stake holes, simultaneously because its vibrator vibrates at the bottom of hole, often cause the part soil layer in stake holes to collapse, therefore, the problem of wearing rock difficulty at the bottom of rotary pile-digging machine hole is the global problem that puzzlement rotary pile-digging machine is efficiently constructed always.
Summary of the invention
The object of the invention is for above-mentioned deficiency of wearing rock instrument, and the one brill rock speed proposed is fast, wear-resistant, drilling tool structure system is independent, unsafe factor can not be produced to rotary pile-digging machine during use, structural safety is reliable, has both been convenient to install and use, and the water filling of being convenient to again keep in repair becomes the multi-functional rock of wearing of tooth and bores.
Technical solution of the present invention is: the lower end of drilling rod socket is fixed on and rotates on water tank heart body, the lower end rotating water tank heart body is connected with drilling rod, the excircle rotating water tank heart body is provided with and rotates water tank overcoat, rotate water tank outer casing outer wall and be provided with water supply connector and water pipe, and exhaust spilling water valve, rotate water tank overcoat excircle and be provided with spline casing, injector is provided with at the lower end inside of spline casing, the water filling piston of injector is connected to and rotates on water tank overcoat, drilling rod is provided with and the centre bore rotating water tank heart body and be communicated with, one end of high-pressure water pipe is connected on injector, the other end is connected on the water injection hole on rotation water tank overcoat, command valve is provided with in drilling rod.
The excircle of the rotation water tank heart body described in technical solution of the present invention is enclosed by lattice, bearing is connected with rotation water tank overcoat with outside framework oil seal.
Spline casing described in technical solution of the present invention is provided with guide slide vertically, and spline casing is connected to by the connecting screw rod be connected on guide slide and rotates on water tank overcoat.
The bottom of the drilling rod described in technical solution of the present invention is provided with 4 sub warheads and breaks heart brill tooth, and installs the increasing tooth jack of reamer tooth, and reamer tooth crown end bores the crown end 2-15cm of tooth higher than the broken heart.
Command valve described in technical solution of the present invention is one way valve.
During drilling tool operation of the present invention both available water pump feed system directly to brill tooth operation place water filling, also water tank and the in-built full water of water filling piston cylinder will can be rotated by alone injector before operation, bore tooth limit operation marginal not water, ensure that boring tooth is cooled in time, allows it be in normal temperature state all the time, the hardness situation of scar and the difference of rotary pile-digging machine power is dug in addition according to brill, the quantity of tooth is bored in Reasonable adjustment configuration, determine the mode of wearing rock, the heart can be taked brokenly to bore tooth for rock stratum (uniaxial compressive strength is at 50-80mpa) the high-power rotary pile-digging machine of common intensity and reamer tooth combinationally uses simultaneously, to improve the Area and Speed boring and dig, subregion can be taked to wear rock to the rock stratum (uniaxial compressive reaches more than 80mpa) of high strength, i.e. first broken rock core, after install the reaming again of (or using special borehole-enlarging drilling tool instead) reamer tooth additional, to concentrate the pressure of stake machine, improve brill tooth and bore the intensity level dug, guarantee that the pressure values of boring tooth can realize wearing rock, the present invention first bores tooth with the broken heart when boring rock and rock core region brill is dug the circular hole that a diameter is about dark 1 meter of 300mm, to destroy the stress structure of rock stratum, treat the rock stratum of reaming afterwards with reamer tooth at the near peripheral trepan of centre bore, finally drag for slag with the further reaming of pick slag bucket.
Advantage of the present invention is: one is concentrate the pressure of a machine that employs in good time and sweep power, substantially increase the pressure values of boring tooth, guarantee under ensureing to bore the prerequisite that do not rupture of tooth the pressure values of each brill tooth be greater than bore dig rock resistance to compression value 5-7 doubly (in experiment multiple authentication sub warhead bore every square centimeter, tooth be stressed reach 5-8 ton situation under can not rupture, and it is fast to bore rock speed); Two is fundamentally solve over when boring tooth brill rock because can not get timely and effective cooling, bore tooth temperature sharply raise, be heated after brill tooth Material Strength sharply decline, not anti abrasive problem, immediately, under the situation cooled there being water, the temperature remains within the normal range substantially to bore tooth temperature, and the degree of wear is greatly low; Three is that near side (ns) district annular vertical after broken rock core wherein outside central hole bores rock reaming, and more easily burst apart in its rock stratum (center has been hole, and the lateral stress of rock stratum is destroyed, and rock can collapse to center and allow); Four is that this drilling tool structure system is independent, can not produce unsafe factor during use to rotary pile-digging machine; Five is that its structural safety is reliable, has both been convenient to install and use, and has been convenient to again maintenance.
