Patent

CA 2503142

The technology disclosed herein provides a system that calculates traveling block position, traveling block velocity and weight supported by the traveling block (38). The system takes all these parameters into consideration when slowing and/or stopping the traveling block (38) when it reaches a crown out (104) or floor out position (106). The result is much safer operation of the traveling block (38) on a workover rig (20), as well as on an oil drilling rig.

L'invention concerne un système doté d'une technologie permettant de calculer une position de moufle mobile (38), une vitesse de moufle mobile (38), et un poids porté par cette moufle mobile (38). Le système prend en considération tous ces paramètres, lors du ralentissement et/ou de l'arrêt de la moufle mobile (38), lorsque celle-ci atteint sa position maximale supérieure de sécurité (104) ou sa position maximale inférieure de sécurité (106). Par conséquent, la moufle mobile (38) fonctionne de manière plus sûre, sur un appareil de reconditionnement (20), ainsi que sur une installation de forage pétrolier.
