Abstract

La présente invention concerne un dispositif de relevage (1) d'objet, telle qu'une pompe (2), disposé au fond d'un forage (3) profond et relié à la surface (5) par un câble (4), ledit dispositif de relevage (1) comportant un bâti (10), des moyens d'entraînement (15, 16, 11, 13a,13b...) aptes à entraîner sans glissement ledit câble (4) et à permettre la remontée ou la descente de l'objet, la partie du câble (4) sortant desdits moyens d'entraînement n'étant alors ni engagée dans une autre poulie ni soumise à l'effort de traction dû à la masse dudit objet, ledit dispositif de relevage (1) comportant des moyens de décoincement (18,19) permettant d'éviter à coup sûr que ledit câble (4) reste coincé dans les moyens d'entraînement.The present invention relates to an object lifting device (1), such as a pump (2), arranged at the bottom of a deep well (3) and connected to the surface (5) by a cable (4), said lifting device (1) comprising a frame (10), driving means (15, 16, 11, 13a, 13b ...) capable of driving without slipping said cable (4) and to allow the ascent or descent of the object, the portion of the cable (4) leaving said drive means then being neither engaged in another pulley nor subjected to the tensile force due to the mass of said object, said lifting device (1 ) comprising unhooking means (18,19) to avoid for sure that said cable (4) remains stuck in the drive means.
