Title
(EN) A DRILLING STRING, THREADED COUPLING, AND ROD ADAPTOR FOR ROTARY DRILLING
(FR) TRAIN DE TIGES DE FORAGE, COUPLAGE FILETÉ ET ADAPTATEUR DE TIGE POUR FORAGE ROTATIF
Abstract
(EN)
A drill string (400) for rotary drilling of underground mining machines including a first elongate drill string member (100) and a second elongate drill string member (100). The first member has a main section (101) and a male end (102), the second member has a main section (101) and a female end (103). The male (102) and female (103) ends have respective threads to provide a thread coupling (401) between the male (102) and female (103) ends, the thread coupling enables the male end (102) to be secured inside the female end (103) such that the male and female ends overlap axially, wherein a thread lead (L2) of the respective threads of the male and the female ends is greater than a diameter (DM, DFI) of the male end (102) and the female end (103).
(FR)
La présente invention concerne un train de tiges de forage (400) pour le forage rotatif de machines d'exploitation minière souterraines, ladite invention comprenant un premier élément de train de tiges de forage allongé (100) et un second élément de train de tiges de forage allongé (100). Le premier élément a une section principale (101) et une extrémité mâle (102), le second élément a une section principale (101) et une extrémité femelle (103). Les extrémités mâle (102) et femelle (103) ont des filets respectifs pour fournir un couplage fileté (401) entre les extrémités mâle (102) et femelle (103), le couplage fileté permet à l'extrémité mâle (102) d'être fixée à l'intérieur de l'extrémité femelle (103) de telle sorte que les extrémités mâle et femelle se chevauchent axialement, une entrée de filet (L2) des filets respectifs des extrémités mâle et femelle étant plus grand qu'un diamètre (DM, DFI) de l'extrémité mâle (102) et de l'extrémité femelle (103).
