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 in rotary pile-digging machine hole bottom, water filling that again can counterboring petrosal foramen becomes the multi-functional rock of wearing of tooth and bores.
Background technology
The various model rotary pile-digging machines that use at present, once run into rock stratum in borehole process, it is all very difficult that existing various drilling tool is worn rock, a pineapple drilling tool reaches the rock stratum of 100mpa left and right to uniaxial compressive strength, within 6-8 hour, can bore 1 meter of left and right of the rock degree of depth, cartridge type core drill is configured on high-power rotary pile-digging machine and uses, approximately 2 hours can 1 meter of left and right of the trepan degree of depth, but its removal of core is but very difficult, conventionally also need after broken rock core, with pick bucket brill, to grab and drag for slag pore-forming more separately, it is in the process of trepan hole wall, because boring the stone end of digging in cannelure, stoped the water in stake hole in time, to flow to the crown portion of boring, boring tooth can not get cooling in time, after brill tooth is heated, its intensity sharply declines, bore tooth consumption very big, 1 meter of left and right of the general trepan degree of depth, must generally change a sub warhead and bore tooth, at the bottom of the hole that use Xiangyang Chang Kan intelligent machine Co., Ltd produces, hydraulic pressure high-frequency percussion is bored, although can realize very fast broken rock core, 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 can not reliably stop the outer collar of swivel joint to turn with its heart portion is same, often there is oil transportation in result, the pipeline of water or winding telescopic drill rod, in stake hole, rupture, because its vibrator vibrates at the bottom of hole, often cause the part soil layer in a hole to collapse, therefore, the problem of wearing rock difficulty at the bottom of rotary pile-digging machine hole is a global problem of the efficient construction of puzzlement rotary pile-digging machine always simultaneously.
Summary of the invention
The object of the invention is the deficiency of wearing rock instrument for above-mentioned, and a kind of brill rock speed proposing is fast, wear-resistant, drilling tool structure system is independent, during use, can not produce unsafe factor to rotary pile-digging machine, structural safety is reliable, has both been convenient to install and use, and the water filling of being convenient to again maintenance 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 rotation water tank heart body, the lower end of rotation water tank heart body is connected with drilling rod, the excircle of rotation water tank heart body is provided with rotation water tank overcoat, rotation water tank outer casing outer wall is provided with water supply connector and water pipe, and exhaust spilling water valve, rotation water tank overcoat excircle is provided with spline casing, inner side, lower end at spline casing is provided with injector, the water filling piston of injector is connected on rotation water tank overcoat, drilling rod is provided with and the centre bore that rotates 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, in drilling rod, be provided with command valve.
The excircle of the rotation water tank heart body described in technical solution of the present invention by lattice enclose, bearing is connected with rotation water tank overcoat with outside framework oil seal.
On spline casing described in technical solution of the present invention, be provided with vertically guide slide, spline casing is connected on rotation water tank overcoat by the connecting screw rod being connected on guide slide.
The bottom of the drilling rod described in technical solution of the present invention is provided with the broken heart of 4 sub warheads and bores tooth, and the increasing tooth jack that reamer tooth is installed, 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 boring tooth operation place water filling, also can before operation, will rotate water tank and the in-built full water of water filling piston cylinder by alone injector, bore tooth limit operation marginal not water, ensure that brill tooth obtains in time cooling, allow it all the time in normal temperature state, according to brill, dig the hardness situation of scar and the difference of rotary pile-digging machine power in addition, rationally adjust the quantity that tooth is bored in configuration, determine the mode of wearing rock, the high-power rotary pile-digging machine in the rock stratum of common intensity (uniaxial compressive strength is at 50-80mpa) can take brokenly the heart to bore tooth and reamer tooth is used in combination simultaneously, to improve, bore the Area and Speed digging, to high-intensity rock stratum (single shaft resistance to compression reach 80mpa more than), can take subregion to wear rock, i.e. first broken rock core, after install (or using special-purpose borehole-enlarging drilling tool instead) reamer tooth reaming again additional, to concentrate the pressure of stake machine, improve and bore the intensity level that tooth brill digs, the pressure values of guaranteeing to bore tooth can realize wears rock, when the present invention bores rock, first with the broken heart, bore tooth and rock core region is bored to the circular hole that digs dark 1 meter of a diameter 300mm, to destroy the stress structure of rock stratum, with reamer tooth, at the near peripheral trepan of centre bore, treat afterwards the rock stratum of reaming, finally with the further reaming of pick slag bucket, drag for slag.
Advantage of the present invention is: the one, and concentrate in good time and used the pressure of stake machine and swept power, greatly improved the pressure values of boring tooth, the pressure values of guaranteeing respectively to bore tooth under guarantee boring the prerequisite that tooth do not rupture is greater than bores the 5-7 doubly (in experiment, multiple authentication sub warhead bores every square centimeter, tooth and is stressed to reach under the situation of 5-8 ton and can not rupture, and it is fast to bore rock speed) that digs rock resistance to compression value; The 2nd, fundamentally solved while boring in the past tooth brill rock timely and effective cooling because can not get, brill tooth Material Strength after brill tooth temperature sharply raises, is heated sharply declines, not anti abrasive problem, having under the instant cooling situation of water, the temperature remains within the normal range substantially to bore tooth temperature, and the degree of wear is greatly low; The 3rd, after broken rock core, the near side (ns) district annular vertical outside heart hole is bored rock reaming therein, its rock stratum more easily burst apart (center has been hole, and the lateral stress of rock stratum is destroyed, and rock can collapse and allow to center); The 4th, this drilling tool structure system is independent, during use, can not produce unsafe factor to rotary pile-digging machine; The 5th, its structural safety is reliable, has both been convenient to install and use, and is convenient to again maintenance.
