Description
Technical field
The utility model belongs to metalwork article processing techniques field, relates generally to a kind of drilling rod.
Background technology
CS-165E type down-the-hole drill is current mine deep hole blasting perforating apparatus, the drilling rod matching used with it that equipment configures adopts unitary design processing structure (accompanying drawing 1), the drilling rod of this unitary design processing, in the process of bar of unloading, be in use particularly subject to long-term rubbing equipment being fixed the upper clipping claw of drilling rod, cause drilling rod wall thinning, drilling rod is easy to, from rubbing fracture, form hidden danger.Upper and lower structure design simultaneously due to drilling rod is different, and makes the claw up and down of fixing drilling rod by the structural allocation of drilling rod, must increase number of fitting parts because upper and lower claw generally can not cause the limitation in use.The drilling rod of unitary design structure is dismantled also inconvenient when wearing and tearing and changing in addition.
Utility model content
In view of problem existing in prior art, the utility model discloses a kind of drilling rod, its drilling rod head, main drilling rod and shank design for split, can be convenient for changing when drilling rod head, shank serious wear, improve the application life of main drilling rod, drilling rod draw-in groove is designed to hexagon, drilling rod is not easily skidded when rubbing, improves its safety factor; Increase the design of shank draw-in groove at drilling rod afterbody, make the claw on rig general up and down, reduce number of fitting parts.
For achieving the above object, the technical solution of the utility model is as follows:
For achieving the above object, the concrete technical scheme that the utility model is taked is: a kind of drilling rod, mainly be made up of drilling rod head, main drilling rod, shank, drilling rod head and being welded and fixed after inserting main drilling rod by drilling rod title junctor and shank convergence body between shank and main drilling rod; Wherein drilling rod head is made up of drilling rod title junctor, drilling rod head draw-in groove, the main wall of drilling rod head, conical internal thread; Shank is made up of shank convergence body, shank draw-in groove, the main wall of shank, conical internal thread; Described a kind of drilling rod, wherein drilling rod head draw-in groove is hexagon; Described a kind of drilling rod, wherein shank draw-in groove is hexagon.
A kind of drilling rod described in the utility model, main drilling rod and drilling rod head, shank junction can be dismantled, conveniently replaced when drilling rod head, shank wearing and tearing, improve the application life of main drilling rod, design is optimized to drilling rod head draw-in groove, be hexagon by the circular design of original drilling rod, drilling rod head is not easily skidded when rubbing fracture, improve safety factor, drilling rod afterbody adds the design of shank draw-in groove, make claw rig being fixed drilling rod general up and down, decrease number of fitting parts.The utility model has the features such as easy to make, safe and reliable, easy to use, energy-saving and cost-reducing, is with a wide range of applications.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Detailed description of the invention of the present utility model is provided as follows below in conjunction with accompanying drawing:
As shown in Figures 2 to 6, a kind of drilling rod described in the utility model, is mainly made up of drilling rod head 1, main drilling rod 2, shank 3; Drilling rod head 1 and being welded and fixed after inserting main drilling rod 2 by drilling rod title junctor 4 and shank convergence body 8 between shank 3 and main drilling rod 2.Wherein drilling rod head 1 is made up of drilling rod title junctor 4, drilling rod head draw-in groove 5, the main wall 6 of drilling rod head, conical external screw thread 7, and drilling rod head draw-in groove 5 is hexagon; Add and man-hour drilling rod head draw-in groove 5 cell wall is thickeied 3mm, when unloading bar, when the claw on rig blocks hexagon drilling rod head draw-in groove 5, not easily skidding, unload bar efficiency and safety factor can be improved.Main for drilling rod head wall 6 is thickeied 2mm, to improve the abrasion resistance of drilling rod head.Shank 3 is made up of shank convergence body 8, shank draw-in groove 9, the main wall 10 of shank, conical internal thread 11, and shank draw-in groove 9 is hexagon; Add and man-hour the cell wall of drilling rod head draw-in groove 9 is thickeied 3mm, the uniform specification of claw up and down on rig can be made, reduce the quantity that spare part is all kinds of.Main for shank wall 10 is thickeied 2mm, to improve the abrasion resistance of drill bit.Be connected by conical external screw thread 7 and conical internal thread 11 between drilling rod with drilling rod, meet the shot hole construction demand that hole depth is greater than single drill pipe.
To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.
