Abstract
The utility model provides a drill rod and a connecting device for a cutting drilling machine, comprising the drill rod and the connecting device. One end of the drill rod is a taper threaded body, the other end of the drill rod is a T-shaped threaded body, the taper threaded body end of the drill rod is connected with a drill bit, the connecting device is a coupler, the T-shaped threaded body end of the drill rod is connected with a power head shaft through the coupler, the coupler has a buffer function, and the drill rod is made of steel pipe material special for a rock drilling drill rod. The drill rod and the connecting device for the cutting drilling machine have high strength, good torsion resistance and shock resistance, meanwhile, the drill rod is connected with the power head shaft through the coupler with the buffer function, so that a power head output shaft, a bearing, a transmission gear and the like are effectively protected against damage under the impact of alternating load, the breakage during drilling is avoided, the service life of the drill rod is greatly improved, the construction efficacy is improved, and the use cost is reduced.
Description
Technical field
The utility model relates to a kind of member of cutting drill, relates in particular to a kind of drilling rod and linkage of cutting drill.
Background technology
Existing cutting drill drilling rod used and linkage exist following not enough:
1. drilling rod generally adopts colliery drilling rod, and the connecting thread of drill bit and drilling rod is tapered tread, and drilling rod low strength during for rockhole is antitorque, shock resistance is poor, and connecting thread fracture and drill rod breaking, bending easily occur;
2. drilling rod is directly connected with unit head axle by adapter sleeve, and unit head axle, bearing, travelling gear etc. easily damage under the impact of fluctuating load, affects the normal construction progress of rig, increases boring cost.
Utility model content
The technical problems to be solved in the utility model is: design a kind of drill rod of cutting drill machine and linkage, to overcome the existing deficiency of above-mentioned prior art.
The technical scheme that the utility model is taked is: a kind of drill rod of cutting drill machine and linkage, comprise drilling rod and linkage, one end of described drilling rod is tapered tread body, the other end is T-shaped threaded body, drilling rod is connected with drill bit by tapered tread body one end, described linkage is shaft coupling, and one end of the T-shaped threaded body of described drilling rod is connected with unit head axle by shaft coupling.
Its further technical scheme is: described shaft coupling is the shaft coupling with pooling feature.
Its further technical scheme be: described drilling rod adopts drill rod special steel pipe material to make.
Owing to adopting technique scheme, a kind of drill rod of cutting drill machine and the linkage of the utility model have following beneficial effect:
1. because the drilling rod of the utility model adopts drill rod special steel pipe material, one end adopts T-shaped screw thread, the other end adopts tapered tread body to be connected with drill bit, this drilling rod possesses the performance of drill rod, rigidity is high, antitorque, shock resistance good, be difficult for bending, no matter be connecting thread intensity, or the intensity of drilling rod own, all far away higher than common drilling rod, can effectively avoid drilling rod boring time, occur that connecting thread fracture and drill rod breaking, bending phenomenon occur, increase substantially application life of drilling rod and efficiency of construction, reduction use cost;
2. because drilling rod is connected with unit head axle by linkage-shaft coupling, can effectively reduce the damage that power head output shaft, bearing, travelling gear etc. cause under the impact of fluctuating load, be conducive to guarantee construction speed, reduce engineering cost.
A kind of drill rod of cutting drill machine below in conjunction with drawings and Examples to the utility model and the technical characterictic of linkage are further described.
Accompanying drawing explanation
Fig. 1: the jackrod structure schematic diagram of the utility model;
Fig. 2: a kind of drill rod of cutting drill machine of the utility model and linkage use view.
In figure:
1-drilling rod, 11-T-shaped threaded body, 12-tapered tread body, 2-drill bit, 3-shaft coupling, 4-unit head axle, 5-unit head.
The specific embodiment
A kind of drill rod of cutting drill machine and linkage, it comprises drilling rod and linkage, one end of described drilling rod is tapered tread body, the other end is T-shaped threaded body, drilling rod is connected with drill bit by tapered tread body one end, described linkage is shaft coupling, and T-shaped threaded body one end of described drilling rod is connected with unit head axle by shaft coupling.
Described shaft coupling is the shaft coupling with pooling feature.
Described drilling rod adopts drill rod special steel pipe material to make.
Above-described embodiment is preferably one of embodiment of the utility model.
In above-described embodiment, described drill rod special steel pipe material is wherein comparatively suitable one, and as an alternative, the material of described drilling rod also can adopt the quality material that other intensity are high, and cost wants high certainly.
