Description
Technical field
The present invention relates to a kind of jet drill carriage device, especially a kind of high-pressure abradant jet current drill carriage device of the drilling technology field that is applicable to dig up mine.
Technical background
In colliery and building stones industry, tunnel exploitation, tunnelling, coal cutting roadway supporting, rock mining etc. all need rock or hard mineral are holed, to realize specific purposes.For example, be used for down-hole stope crossheading driving gas advance drainge, utilize crossheading to carry out the face gas extraction; Be used for Bumping Pressure in Coal Layers control and the boring of other geotechnical engineering constructions and unload crushing rock.And in the driving in underground coal mine tunnel, need to be in the non-destructive situation of tunnel rock, punch and creep into, because there are many inflammable, explosive dangerous gases in the down-hole, and narrow space, complicated condition in the underground passage can not use electrogas welding etc. easily to produce pyrophoric machine cuts mode and hole.The rig of prior art is to adopt the drilling rod rotation, and the principle of the broken rock of driving abradant jet drill bit is made, and its disadvantage is that efficiency of breaking rock is low, and penetration rate is slow.Therefore this rig can't satisfy the special operations such as mining industry and geotechnical engineering, and safe, practical on-mechanical rig is badly in need of in the down-hole.
At present, the water-jet technology development is swift and violent, has been widely used at numerous areas such as mining, aviation, building, chemical industry, metallurgy, municipal engineering, Metal Cutting, broken rock and cleanings.Because water jet is a kind of cold bore mode, can effectively avoid the generation of spark in the cutting process, its boring principle mainly relies on by measuring of the hydrone of high-voltage high-speed ejaculation concentrated, the enormous impact power of shooting object, can process operation to being hit thing, such as boring, the cutting to material.In the application of reality, cutting some surface materials such as loose, soft is successful, but then helpless for comparatively hard rock or iron and steel, how particularly the mine under complicated environmental condition and building stones factory improve this class boring effect and are the on-the-spot large problem that solves be badly in need of.
Summary of the invention
Technical problem: the objective of the invention is to overcome the weak point in the prior art, provide a kind of simple in structure, boring is effective, be adapted under the Mine Complicated ambient conditions, satisfy the high-pressure abradant jet current drill carriage device of specific (special) requirements.
Technical scheme: high-pressure abradant jet current drill carriage device of the present invention, comprise creeper undercarriage, rig, the high pressure pumping plant, water tank, grading material device, the water under high pressure pigtail device that are provided with operating desk, connect successively through hydraulic tube at creeper undercarriage, rig is located at the front portion of water under high pressure pigtail device, drilling rod tail end on the rig links to each other with water under high pressure pigtail device, and the front end of drilling rod is provided with the abradant jet drill bit; Described grading material device comprises the abrasive material case, is located at side by side two supports in the abrasive material case, is respectively equipped with abrasive can in two supports;
Described water under high pressure pigtail device comprises housing, is located at the hollow shaft in the housing, the front portion of hollow shaft is provided with the drive end bearing bracket that fixes with the housing front end, the afterbody of hollow shaft is provided with the intake end cover that fixes with the housing rear end, be arranged with rolling bearing between hollow shaft and the housing, be provided with the pressure ring and the collar that act on the hollow shaft in the intake end cover, be provided with axle between the collar and the hollow shaft and seal with Che Shi, housing is provided with the soket head cap screw of fixed pressure ring;
Described abradant jet drill bit comprises the cylindrical drill body that is connected with conical head, be symmetrically welded with a plurality of Buddha's warrior attendant composite sheet on the conical surface of cylindrical drill body, symmetry has two tapped through holes on the cylindrical drill body, be provided with carboloy nozzle in the tapped through hole, the rear end of cylindrical drill body has internal thread hole, the front end conical head of cylindrical drill body has eccentric orfice, and the connecting hole between eccentric orfice and the internal thread hole is tubaeform.
Be provided with dust ring between described drive end bearing bracket and the hollow shaft; The nozzle diameter of described carboloy nozzle is 2-3mm; Described a plurality of Buddha's warrior attendant composite sheet is 2-6.
Beneficial effect: principle is cut in cold cut in the present invention and the abradant jet bit technique combines, by hybrid mode before the abrasive material, abrasive material and water under high pressure are evenly mixed in abrasive can, form mixed liquor, be connected to rig by pipeline, and by the ejaculation of abradant jet drill bit, form the abrasive grain subflow-abradant jet with flank speed.Compare with pure water jets, abradant jet is changed into the abrasive grain subflow to the high frequency bump and erosion effect of material with pure water jets to the static pressure continuous action of material, and its action effect greatly takes on a new look.Front hybrid mode, abrasive material and water mix, fully, after emitting through high pressure, more outstanding to the action effect of material.Its device no-spark in boring procedure can not brought out gas explosion, and also has the depositing dust effect.Utilize high-pressure abradant jet current that hard ware material is holed, safe and effective, guarantee the requirement of various boring work under the complicated environmental condition, saved a large amount of human and material resources, medium---water, abrasive material---used during boring is cheap, safety and sanitation, can not bring environment pollution.The abradant jet drill bit is along with drilling rod rotates, and the abradant jet that sprays from carboloy nozzle can impact groove one around eccentric orfice, makes the rock face drill hole an isolated projection occur, more is conducive to the fragmentation of rock.During the work of abradant jet drill bit, abradant jet elder generation fractured rock, then the Buddha's warrior attendant composite sheet acts on the rock face.Owing to greatly improved drilling efficiency when abradant jet has reduced bit wear with catalase.Prior art is compared characteristics such as having speed is fast, efficient is high, long service life, easy maintenance, has a good application prospect.
