Description
One, technical field
The utility model relates to a kind of drawing-in type wire line coring Hydro-efflux Hammer drilling tool, is suitable for mine core drilling application.
Two, background technology
What geological drilling was encountered conventionally is broken scall, and coring, taking rate is not high often.
For addressing the above problem, long-lived " research of series of high efficiency Hydro-efflux Hammer and the application " paper delivered that waits of Soviet Union of open Liao Yipianyou of " mineral exploration engineering (rock and soil drilling engineering) " the 37th the 3rd phase of volume in 2010 China Geology Academy of Science and Technologys Exploration Technology Research Institute, this Publications relates to one " wire line coring Hydro-efflux Hammer ", along with the top connection of Beijing exploration engineering Research Institute, top nozzle, upper valve, upper cylinder sleeve, upper piston, upper exterior tube, block stamp body, lower piston, lower cylinder sleeve, hammer axle, the ring of passing on Gong, applying of the main member compositions such as impulse-bearing ring " SYZX series wire line coring Hydro-efflux Hammer ", for the complete stratum of generality, the requirement of matter design greatly contentedly, taking rate can be up to 90～100%, and for the mantle of shallow-layer, can also be two-tube by single action, get core without pump, multi-functional local reverse-circulation, little beating greatly expanded, more few beating the technological means such as is carried and is ensured taking rate.
Follow the new departure of " attack deeply look for blind, enclose ore deposit and look for ore deposit ", probing work progressively to striding forward compared with deep hole, the boring ratio of the above hole depth of 800m was and continues expansion trend in the coming years.In work progress, the technological means of taking above-mentioned shallow-layer all can be large because of labour intensity, high being difficult to of cost adopt, and occurs bad ground in darker hole section, and taking rate has just become the difficult point in construction.
Low based on deep hole bad ground taking rate, though the impact shock of wire line coring Hydro-efflux Hammer can reduce the degree of stopping up, still have certain limitation.Because bad ground lithology is taking fines as main, loose crushing, extremely grow at joint, crack, rock itself lacks binding material, disturbance and just washing away of flushing liquor once drill bit spread out, and are difficult to enter inner tube or have entered inner tube jump ring to block, so directly cause taking rate not high.
Three, summary of the invention
The purpose of this utility model is to provide a kind of drawing-in type wire line coring Hydro-efflux Hammer drilling tool, and it can solve the problems such as deep hole bad ground core recovery percentage is low, labour intensity is large.
For achieving the above object, the utility model design is carried out in the following way:
Drawing-in type wire line coring Hydro-efflux Hammer drilling tool, it comprises in Hydro-efflux Hammer outer tube that matched in clearance arranges top connection successively, top nozzle, upper valve, upper cylinder sleeve, inner sleeve upper piston, block stamp body, lower piston, the upper exterior tube of lower cylinder sleeve, hammer axle, the pass on Gong wire line coring Hydro-efflux Hammer of the impulse-bearing ring of ring and the upper reamer of Hydro-efflux Hammer outer tunnel end overcoat composition of inner sleeve, it also comprises in drilling tool outer tube successively that button silk connects and holding of inner sleeve nozzle is set rushes joint, hold spray apparatus, lower contact, inside establish the spring housing of single acting connector and adjusting joint, filter disc, inner tube, injection suction assembly and the bottom spraying type subland drill of clip spring seat and overcoat UR device composition thereof, spray suction assembly inner sleeve nozzle hold the pass on Gong impulse-bearing ring end of ring of the inner sleeve of rushing joint one end screwed connection wire line coring Hydro-efflux Hammer, spray the other end clip spring seat screwed connection bottom spraying type subland drill of suction assembly, in the labial surface of bottom spraying type subland drill, be provided with the interior step of drill bit and labial surface and be provided with one-level step, two stage steps outward, one-level step is evenly equipped with drill bit cross eye.
When high pressure washing liquid that water pump is sent here is when in Hydro-efflux Hammer hammer axle, aperture nozzle connection enters nozzle, because nozzle chamber is that taper and jet hole section are less, therefore, flushing liquor is approximately injected and is held in spray apparatus with 13～15m/s speed, under the effect of this high-speed jet, nozzle and the liquid holding around spray apparatus, taken away a part and form negative pressuren zone by jet, under the effect of pressure differential, fluid in the inner tube of bottom is pumped to and is held spray apparatus annulus around inside by filter disc, high velocity liquid stream and the liquid sucking are just holding spray apparatus mixing, carry out the rear both sides hydrophthalmia that flows into lower contact of energy transmission and exchange, by the annular gap of inner tube and drilling tool outer tube, the cross eye uniform from the drill bit of bottom spraying type subland drill penetrates, the not direct erosion rock core of flushing liquor, guarantee the integrality of rock core.
The utility model is because combined wire line coring Hydro-efflux Hammer, injection suction assembly and specific bottom spraying type subland drill, improve inner tube assembly, so both collected feature separately, can also initiatively draw rock core, avoid the direct erosion core of flushing liquor, reduce the taking rate of pump pressure, raising water-sensitive strata, saved greatly manpower and materials; Owing to bottom spraying type subland drill being provided with to step in drill bit, two-stage step and drill bit cross eye, make drill bit act on rotary torque, axial pressure and axial impact force, so be conducive to fractured rock, stop up unfreezing and reduce core autogenous grinding simultaneously simultaneously; In addition change the essential structure of drawing-in type wire line coring Hydro-efflux Hammer drilling tool owing to not lying in, so integral structure is easy to apply.
