Activating Tool For Displacing Of A Component In A Well Tube And Method For Adjusting The Activating Tool

摘要

This invention relates to an activating tool (1) for connecting to and displacing a component (40) in a well tube (4), activating tool (1) includes a driving device (8) axially displaced in two axial directions; a sleeve-shaped release element (14) with an annular end portion (52); a gripper holder (20) arranged axially displaceable in release element (14) and displaced by driving device (8); axially longitudinal recesses (24) in gripper holder (20); at least two radially displaceable gripping elements (26) spring-biased in a radial outward direction, positioned in respective recesses (24) and complementarily fitting respective cut-outs (42) in the component (40), and each gripping element (26) has a slanted rear portion (48); gripping elements (26) retracted into release element (14) in passive positions of gripping elements (26), and gripping elements (26), at least partially, displaced out of release element (14) in active positions of gripping elements (26) so end portion (52) hits slanted rear portions (48) of gripping elements (26) when gripper holder (20) is pulled inwards in release element (14), gripping elements (26) optionally switched between active and passive positions. A method for changing gripping element (26) in the activating tool (1) is described.

主权项

1. An activating tool (1) for connecting to and displacing a component (40) in a well tube (4), the activating tool (1) including:
a driving device (8) which may axially be displaced in two axial directions; a sleeve-shaped release element (14) provided with an annular end portion (52); a gripper holder (20) which is arranged in an axially displaceable manner in the release element (14) and is displaced by the driving device (8); axially longitudinal recesses (24) in the gripper holder (20); at least two radially displaceable gripping elements (26) spring-biased in a radial outward direction, positioned in respective recesses (24) and complementarily fitting respective cut-outs (42) in the component (40), and each gripping element (26) being provided with a slanted rear portion (48); so that the gripping elements (26) are retracted into the release element (14) in the passive positions of the gripping elements (26), and the gripping elements (26) are, at least partially, displaced out of the release element (14) in the active positions of the gripping elements (26), characterized in that the end portion (52) hits the slanted rear portions (48) of the gripping elements (26) when the gripper holder (20) is pulled inwards in the release element (14), so that the gripping elements (26) may optionally be switched between taking an active position and a passive position.
