Description
Technical field
The present invention relates to coal mine machinery exploitation field of tool, relate in particular to a kind of soft projecting coal bed and staggered coal-bed gas extraction borehole equipment of soft or hard under the coal mine that is used for, specifically be meant a kind of many ribs of monolithic drilling rod.
Background technology
At present; The working drilling rod form of coal mine down-hole drilling is varied; Mainly contain round bur bar, auger stem and triangular drilling rod etc., but round bur bar deslagging gap is too small, it is excessive that auger stem then consumes the rig moment of torsion; Triangular drilling rod then can not be derived cinder when bit freezing, therefore all can not realize deep well drilling.
Disclosed Chinese invention patent " irregularly shaped multi-land notch groove drill rod "; Patent publication No. is CN101566049A; Scribed discontinuous helicla flute on common many ribs drilling rod surface; Utilize the coal dust at the bottom of the seamed edge of drilling rod stirs the hole, utilize discontinuous helicla flute assist deslagging, in coal mine down-hole drilling is constructed, obtained good effect.But should abnormal shape cutting drilling rod be split-type structural, the joint at body of rod two ends and the body of rod be pegged graft perhaps friction welding together through interference fit.Use contrast to find that the drilling rod manufacturing procedure of split-type structural is many through producing with actual, production efficiency is low; Drilling rod intensity is lower; And no matter the joint and the body of rod are the split type drilling rods that couples together through interference fit or friction welding mode, all have the problem of diameter of bore sudden change at joint and body of rod connecting portion, thereby cause fluid media (medium) poor in the trafficability characteristic of drill pipe bore; And have energy loss, reduced drilling efficiency.In addition, the tangent plane of irregularly shaped multi-land notch groove drill rod is the plane, exists annular clearance little, the inefficient shortcoming of row's powder.
Summary of the invention
The technical problem that the present invention will solve is to the existing in prior technology weak point, provides that a kind of structure design is ingenious, drilling rod intensity high, the endoporus deslagging is unobstructed, and annular clearance is big, high a kind of many ribs of the monolithic drilling rod of row's powder efficient.
Technical solution of the present invention is; Following a kind of many ribs of monolithic drilling rod is provided; Comprise that inside is provided with the drilling rod body of circulation groove, described drilling rod body two ends are respectively equipped with quick union, and described drilling rod body outer wall is provided with and is no less than one helicla flute; Described drilling rod body surface is provided with and is no less than two excision face, and described excision face forms seamed edge with drilling rod body outer wall ring surface.
Adopt the present technique scheme, the present invention sets up excision face, and forms seamed edge with drilling rod body annular outer wall, and its structure has increased the annular space area of passage, and a plurality of seamed edges of drilling rod body can stir the coal dust of hole bottom sediments again simultaneously; The helicla flute that is provided with has the effect of auxiliary deslagging, after a plurality of seamed edges of drilling rod body stir coal dust, and under the effect of scouring media, can be fast and effeciently outside the tap through helicla flute; Snap joint is set, two drilling rods of connection that can be easily and fast; In addition, all-in-one-piece jackrod structure has improved the torsional strength and the flexural strength of drilling rod, has prolonged the application life of drilling rod.
As preferably, the quick union that described drilling rod body two ends are provided with is respectively male joint and female joint, and described male joint is provided with external screw thread, and female joint is provided with internal thread.Adopt the present technique scheme, be of value to two rapid abutting joint between the drilling rod, and have certain bonding strength.
As preferably, described helicla flute and internal and external screw thread all are on the drilling rod body, directly to process, with the drilling rod body be integral structure.Adopt the present technique scheme, be of value to the manufacturing procedure that reduces drilling rod, enhance productivity, reduce production costs.
As preferable, described excision face circularizes around drilling rod body outer wall, and evenly arranges.Adopt the present technique scheme, be of value to and reduce the vibrations that produce when rotating, rotary course is more steady.
As preferable, the excision degree of depth h1 of excision face middle part is greater than or equal to the excision degree of depth h2 of two ends joint area on the described drilling rod body outer wall.Adopt the present technique scheme, be of value to increase annular space area of passage, can better stir the coal dust of hole bottom sediments again, be convenient to discharge.
As preferable, described spiral fluted cross section is a circular arc or square; Described excision face is plane or curved surface; Described drilling rod body is different according to the excision face excision degree of depth, is divided into helicla flute continuity drilling rod or helicla flute discontinuity drilling rod body.Adopt the present technique scheme, can select suitable spiral fluted cross sectional shape, excision face shape and the excision face excision degree of depth, can effectively reduce the processing cost of drilling rod according to what of coal dust discharge rate in the actual working environment, and the bigger income of acquisition.
