Title
(EN) DYNAMOMETRIC MEASURING DEVICE FOR DRILL PIPE
(FR) DISPOSITIF DE MESURE DYNAMOMETRIQUE POUR TIGE DE FORAGE
Abstract
(EN)
The invention relates to a dynamometric measuring device for drill pipe comprising, integral with the rotating pipe (1), sensors, (20, 40, 60, 70, 50) and a first electronic circuit (3) for the conditioning of signals provided by such sensors, characterized in that the electronic circuit (3) is integral with rotating parts (1), the sensor being arranged in a groove (10) and the measuring signals being transmitted to a fixed part (110, 9, 81) by means of a rotating collector assembly (80) with fixed brush (81) and the crossing of the collector (80), brush (81) assembly being effected with a zero current.
(FR)
La présente invention concerne un dispositif de mesure dynamométrique pour tige de forage comprenant, solidaires de la tige tournante (1), des capteurs (20, 40, 60, 70, 50) et un premier circuit électronique (3) de conditionnement des signaux fournis par ces capteurs, caractérisé en ce que le circuit électronique (3) est solidaire des pièces tournantes (1), les capteurs sont disposés dans une gorge (10) les signaux de mesure sont transmis à une partie fixe (110, 9, 81) par un ensemble collecteur tournant (80) balai fixe (81), et la traversée de l'ensemble collecteur (80) balai (81) s'effectue à courant nul.
