Description
Technical field
The utility model relates to coal mining drilling rod, relates in particular to tunnel probing drilling rod.
Background technology
Current domestic coal mine gallery is drilled drilling rod used, mainly contains geology round bur bar, geology auger stem, Three-edged drill stem.The application of geology round bur bar is more extensive, but does not possess slagging structure, easily causes bit freezing to affect underground construction; Geology auger stem surface, with helical blade, is mainly used in compared with hard coal seam, using and often occur inhaling brill compared with weak seam, causes drilling tool locking, ruptures and comes off, and reduces drilling efficiency, strengthens and consumes; Three-edged drill stem utilizes poor stirring the in footpath to play the greasy reinforcement effect of smearing to drill hole wall, has reduced the collapse hole phenomenon of run coal layer, but owing to there is no power slagging structure, has defect creeping into aspect deslagging, affects boring progress.
Utility model content
The purpose of this utility model, just be to provide a kind of coal mine gallery probing Novel drill rod, when creeping into, can stir boring mud, hole wall is carried out to the greasy reinforcing of smearing, can carry out highly effective slag draining again, in hole, residue is few, and drilling rod can be drilled at random angle, realize the deep drilling pore-forming of drilling rod, be convenient to jointed rod; Prevent locking, rupture, come off, reduce boring cost, accelerate boring progress.
Task of the present utility model completes like this: design and produce a kind of coal mine gallery probing thrust ash melting type auger stem, drilling rod main body is Rhizoma Sparganii hollow lever, body of rod surface arranges spiral gear piece, body of rod two ends are respectively male joint, female joint, and male joint end is screwed pipe, and center, female joint end has inner bolt hole, the female joint of the front body of rod can coordinate with the male joint of the back body of rod, link into an integrated entity, male joint and female joint have centre bore, are communicated with body of rod endoporus.The body of rod is positive triangle rounded edges uniform thickness hollow stem, body of rod surface uniform welding spiral gear piece, and spiral gear piece outer rim is projected as take the positive circle that body of rod kernel of section is the center of circle.Male joint and female joint are the cylindrical bar that diameter is not more than body of rod circumscribed circle, are connected and are welded respectively with the tapered transition in two ends of the body of rod, and male joint is welded and the wide identical spiral gear piece of body of rod spiral gear piece marginal tooth with the cylindrical bar surface of female joint.Body of rod two ends are male joint, the female joint that diameter is not more than the cylindrical shape of body of rod circumscribed circle, the tapering transition being connected with the body of rod adopts high temperature friction welding, the body of rod and male joint, female joint are connected as a single entity, the spiral gear piece on body of rod surface adopts high strength steel processing, its yield strength is high, stress is little, the joint face of spiral gear piece and the body of rod fits like a glove, be welded and fixed, spiral gear piece, according to the selected lead angle of the factors such as seam hardness and cinder particle and pitch, forms helical turbine Auger shape on body of rod surface.Spiral gear piece is welded in male joint, female joint place equally, is connected according to same lead angle with the spiral gear piece of the body of rod, forms one-piece auger structure, make the integral-rotation diameter of drilling rod keep unified, assurance cinder and rock disintegrating slag are discharged smoothly, prevent bit freezing and creep into collapse hole, improve drilling efficiency.
According to technique scheme, implement, prove of the present utility model reasonable in designly, be connected firmly, deslagging is smooth and easy, has effectively avoided bit freezing to cause the phenomenons such as fracture, locking, has reduced material consumption, reduce boring cost, saved manpower man-hour, improved drilling efficiency and drilling quality, can in angular range, drill arbitrarily, realize deep drilling pore-forming, applied widely, boring progress is fast, good in economic efficiency, reached preferably predetermined object.
