The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
Referring to Fig. 1-2, the air chamber 1 that the utility model comprises apron sleeve pipe 6 and is arranged on apron sleeve pipe 6 tops, is provided with the central tube 12 of the bottom of stretching out apron sleeve pipe 6 in apron sleeve pipe 6, and central tube 12 coaxially arranges with apron sleeve pipe 6; The top of central tube 12 is stretched in air chamber 1, and the bottom of central tube 12 is provided with the thread 11 for being connected with drill string, is also provided with the centralizer 10 of multiple wing shape on the bottom sidewall of central tube 12; Between apron sleeve pipe 6 and central tube 12, be provided with one deck combination hammer, and combination hammer is evenly arranged on by five the down-hole hammer that central tube makes progress for 12 weeks and forms; Down-hole hammer comprises down-the-hole hammer body 4 and the down-the-hole tup 9 being connected with down-the-hole hammer body 4 bottoms; Air chamber 1 is connected with the piston-cylinder in each down-the-hole hammer body 4 by a minute gas passage 2 respectively, and the top of down-the-hole hammer body 4 is provided with the jointing 3 being connected with minute gas passage 2, and the bottom of apron sleeve pipe 6 is provided with the end lip backplate 8 being enclosed within on central tube 10 and down-the-hole hammer body 4.In addition, be provided with upper mounted plate 5 and bottom plate 7 in apron sleeve pipe 6, upper mounted plate 5 and bottom plate 7 are axially enclosed within on central tube 12 and down-the-hole hammer body 4 along central tube 12.
In addition, be subject to the impact of apron sleeve pipe 6 diameters and down-hole hammer size, combine sub-hammer can also be arranged to two-layer or two-layer more than, the down-hole hammer that forms combination hammer also can arrange the number of down-hole hammer according to actual conditions, be not limited only to given five of the present embodiment.
Operating principle of the present utility model is as follows:
The utility model adopts down-hole hammer impact principle, several the Wind Volume high pressure air compressors high pressure draught producing in parallel is transported to drill string central passage by high-pressure rubber pipe, drill string is connected together by thread 11 and central tube 12, high pressure draught passes through central tube 12 to the interior introducing pressure-air of air chamber 1, pressure-air is in the interior focused energy of air chamber 1, pressure in air chamber 1 acquires a certain degree, just by a minute gas passage 2, the pressure-air of focused energy is distributed to the piston-cylinder in each down-the-hole hammer body, piston promotes tup percussion drilling forward, because air chamber 1 is distributed to each piston-cylinder by a minute gas passage 2 by gases at high pressure simultaneously, therefore, piston promotes tup to carry out reaming and creeps into also and carry out simultaneously, so just can utilize air pressure to realize each down-hole hammer and impact acting, thereby reach quick raising boring pore-forming, reduce construction period, the object reducing costs.At air chamber 1 during to piston/cylinder distribution of gas, pressure in air chamber 1 also can reduce gradually, when being reduced to certain pressure, air chamber 1 will interrupt to the piston/cylinder air feed in each down-the-hole hammer body, down-hole hammer stops impacting acting, and air chamber 1 is also gathering strength simultaneously again, treats that energy is enough that pressure reaches a certain size, can again distribute gases at high pressure, make a down-hole hammer impact acting simultaneously.In down-hole hammer acting, the rock dust that boring produces is owing to being subject to stopping of lip backplate 8 on earth, simultaneously because the utility model whole device under the drive of drill string can present circular motion, therefore, in space under the centrifugal action that rock dust produces at circular motion outside apron sleeve pipe 6, move, finally by the tunnel of foot of hole, the rock dust of boring generation is transported.In addition, the utility model promotes the piston acting in down-hole hammer with pressure-air, and therefore, the utility model, without mud materials, has further reduced cost.
The utility model adopts three-dimensional space drawing technology, and drilling process under simulation well adopts down-hole hammer operating principle, by rigorous science, calculates, and reasonable integrated down-the-hole hammer body, realizes high-efficient impacting down-the-hole and creep into object, completes construction task.
The utility model has been applied impactor rock drilling principle, at ground consisting of hard rock, realizes Faster Drilling Techniques, realizes heavy caliber drawing-off gas hole or default mine emergency rescue hole construction.Heavy caliber drawing-off gas hole or mine emergency rescue hole construction, by the requirement of raising boring technical matters, fast drilling stratum is realized heavy caliber and is become well target drill.
The utility model, according to raising boring conditional request in tunnel, has proposed the anti-well pneumatic down-hole hammer of a kind of cluster type heavy caliber.Through evidence, construction aperture is 700mm, and hole depth is 340m, estimates to complete for 25 days.And practical effect shows, from beating with pneumatic down-hole hammer direct circulation, guide hole, to lower surface pipe, well cementation again to using the moving down-hole hammer raising boring of the anti-gas well gas of cluster type heavy caliber of the present utility model, amounts to 9 day time, and the rotating hours only has 30 hours.By the drilling method comparative analysis with conventional, drilling efficiency has improved decades of times, cost savings more than 60%.Therefore, drilling efficiency of the present utility model is high, can significantly shorten construction period, alleviate labor strength, reduce drilling cost, solved the thorny problem existing in current heavy caliber coal mine gas drainage well and mine rescue well construction.
