Abstract
The utility model discloses a detachable drill rod which is used for punching equipment for deep hole blasting of a mine. The detachable drill rod is mainly formed by a drill rod head (1), a main drill rod (2) and a drill rod tail (3); the drill rod head (1) and the drill rod tail (3) are welded and fixed with the main drill rod (2) after a drill head jointing body (4) and a drill rod tail jointing body (8) are inserted into the main drill rod (2). When being severely abraded, the drill rod head (1) and the drill rod tail (3) can be replaced conveniently, and the service life of the main drill rod (2) is prolonged. A drill rod head clamp slot (5) and a drill tail clamp slot (9) are designed to be hexagonal, so the drill rod does not easily skid during twisting, and the safety factor is improved. The drill rod tail clamp slot (9) is additionally arranged at the drill rod tail (3), so a clamp pawl on a drill rig is universal up and down and the number of accessories is reduced. The detachable drill rod has the advantages of convenience in manufacturing, safety, reliability, convenience in use, energy saving, emission reduction and the like, and has wide application value.
Description
Technical field
The utility model belongs to metalwork goods processing technique field, relates generally to a kind of detachable 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 configuring on equipment is to adopt integral type design processing structure (accompanying drawing 1), the drilling rod of this integral type design processing, in use particularly in the process of bar of unloading, be subject to the long-term rubbing of the upper clipping claw of fixing drilling rod on equipment, cause the attenuation of drilling rod wall, drilling rod is easy to, from rubbing fracture, form hidden danger.Simultaneously due to the upper and lower structure design difference of drilling rod, and make the claw up and down of fixing drilling rod must be by the structure configuration of drilling rod, because upper and lower claw can not generally cause the limitation in use to increase number of fitting parts.The dismounting in the time that wearing and tearing are changed of the drilling rod of integral type project organization is also inconvenient in addition.
Utility model content
In view of existing problem in prior art, the utility model designs and discloses a kind of detachable drilling rod, disclosed detachable drilling rod, its drilling rod head, main drilling rod and shank design for split, in the time of drilling rod head, shank serious wear, can be convenient for changing, improve the application life of main drilling rod, drilling rod draw-in groove is designed to hexagon, make drilling rod be difficult for skidding in the time of rubbing, improve 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 concrete technical scheme that the utility model is taked is: a kind of detachable drilling rod, be mainly to be formed by drilling rod head, main drilling rod, shank, be welded and fixed after inserting main drilling rod by drilling rod title junctor and shank convergence body between drilling rod head and 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; The detachable drilling rod of described one, wherein drilling rod head draw-in groove is hexagon; The detachable drilling rod of described one, wherein shank draw-in groove is hexagon.
The detachable drilling rod of one described in the utility model, main drilling rod and drilling rod head, shank junction can be dismantled, conveniently replaced in the time of drilling rod head, shank wearing and tearing, improve the application life of main drilling rod, drilling rod head draw-in groove is optimized to design, be hexagon by the circular design of original drilling rod, make drilling rod head in rubbing, be difficult for the fracture of skidding, improve safety factor, drilling rod afterbody has increased the design of shank draw-in groove, the claw that makes to fix on rig drilling rod is general up and down, has reduced number of fitting parts.The utlity model has the features such as easy to make, safe and reliable, easy to use, energy-saving and cost-reducing, be with a wide range of applications.

Detailed description of the invention
Provide detailed description of the invention of the present utility model below in conjunction with accompanying drawing as follows:
As shown in Figures 2 to 6, the detachable drilling rod of one described in the utility model, is to be mainly made up of drilling rod head 1, main drilling rod 2, shank 3; After inserting main drilling rod 2 by drilling rod title junctor 4 and shank convergence body 8 between drilling rod head 1 and shank 3 and main drilling rod 2, be welded and fixed.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 man-hour by drilling rod head draw-in groove 5 cell wall thickening 3mm, in the time unloading bar, when the claw on rig blocks hexagon drilling rod head draw-in groove 5, be difficult for skidding, can improve unload bar efficiency and safety factor.Main drilling rod head wall 6 is thickeied to 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 man-hour by the cell wall thickening 3mm of drilling rod head draw-in groove 9, can make the uniform specification of claw up and down on rig, reduce all kinds of quantity of spare part.Main shank wall 10 is thickeied to 2mm, to improve the abrasion resistance of drill bit.Between drilling rod and drilling rod, be connected by conical external screw thread 7 and conical internal thread 11, meet the shot hole construction demand that hole depth is greater than single drilling rod.
