In recent years, the price of gold and diamond continues to skyrocket, so that the gold ore deposit mining amount relevant with diamond mine increases gradually, and the degree of depth and the width of exploitation increase gradually, by 3 initial rice diameters, 7.5 rice diameters till now, performance requirement to drilling tool is stricter, needs larger bearing capacity and anti-twisting property.At present, the mine drilling rod of largest domestic bore is 6 inches, and the most frequently used is 9～10 inches in the world.Nowadays, many rigs contractor is at the transformation and upgrade drilling equipment or make new rig, and these rigs bore wide reaching more than 8 meters, bore so wide advancing, and needs a large amount of investments and advanced Ultradeep Drilling Technology.
Summary of the invention
The purpose of this invention is to provide a kind of anti-twisting property that strengthens the probing drilling rod, improve the effective width of probing, and finally improve the 14-3/4 inch super large caliber mine locating drilling rod of drilling efficient.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: a kind of 14-3/4 inch super large caliber mine locating drilling rod, comprise the drilling rod body with through hole, one end of described drilling rod body is male end, the other end of described drilling rod body is female end, and the screw thread of described male end and female end has tapering, the conical surface path of described male end is 264～266mm, the large footpath of the conical surface of described male end is 282～285mm, and the conical surface length of described male end is 219～221mm; The outside of described female end is provided with the reamer hole, and large footpath, described reamer hole is 284～286mm; The taper hole path of described female end is 253～255mm, and the large footpath of the taper hole of described female end is 272～274mm, and the taper hole length of described female end is 194～196mm.
Further, the screw thread effective length of described male end is 189～191mm.
Further, the screw thread effective length of described female end is 194～196mm.
The present invention has following beneficial effect: a kind of 14-3/4 inch super large caliber mine locating drilling rod of the present invention, comprise the drilling rod body with through hole, one end of described drilling rod body is male end, the other end of described drilling rod body is female end, and the screw thread of described male end and female end has tapering, and external screw thread and internal thread are complementary, thereby so that the connection between the drilling rod is more tight, firm; And the increase of bore has strengthened the anti-twisting property of probing drilling rod, has improved the effective width of probing, has improved recoverable reserves, has shortened the probing cycle, has prolonged the application life of drilling tool.
