Abstract
Selon l'invention, un système d'accouplement et de désaccouplement des extrémités de chevilles de tiges de pompage (36) et de manchons d'accouplement (35) utilise un système à commande hydraulique de têtes à griffes à entraînement radial (28, 29, 30) interchangeables pouvant accepter différentes tailles de tiges de pompage. Un système de torque (70) adjacent au système de têtes à griffes (28, 29, 30), également à commande hydraulique, emploie une extrémité libre (96) à couplage pivotant sur une clé dynamométrique entrant en prise avec un pan de manoeuvre (37) sur une tige de pompage (36), à son extrémité opposée. L'accouplement (35) est solidement réalisé sans déparer la surface d'accouplement pendant que le couple nécessaire pour accoupler ou désaccoupler le raccordement est appliqué de manière rapide et contrôlable. Le système peut également être utilisé pour obtenir, avec des tiges de pompage (36) préassemblées, un accouplement (35) présentant une précontrainte précise, avec un modèle de raccordement amélioré. Un train de tiges de pompage peut ainsi être assemblé rapidement sur le terrain dans des conditions de précontrainte constantes optimales au niveau de chaque raccordement.
