Abstract

Il est décrit un système de chevalet de pompage avec contrepoids qui comprend une structure support, un actionneur linéaire avec un carter et une tige, une première poulie entraînée par la tige, une deuxième poulie fixée au-dessus de la première poulie, un élément flexible allongé, et un poids entraîné par la tige. Le carter est orienté verticalement et monté sur la structure support au-dessus dune surface de sol. La tige a une première extrémité reçue dans le carter, et une extrémité de raccordement qui sétend du carter et entraîne la première poulie et le poids. Lactionneur linéaire fait passer la tige dune position déployée à une position rentrée. Lélément allongé passe autour des poulies et a une première extrémité fixe relativement au carter et une deuxième extrémité raccordée à une tige de surface, de sorte que le mouvement alternatif de la tige fait que la tige de surface se déplace verticalement et que le poids agit comme contrepoids mécanique.
