Abstract
An apparatus for guiding an anti-rotation key installation tool includes at least one magnet mounting member. A tool positioning member is coupled to the magnet mounting member and has a first end and a second end. An installation tool positioning channel extends from the first end to the second end of the tool positioning member and has an opening at the first end of the tool positioning member for accepting a portion of the anti-rotation key installation tool. At least one mechanically switchable frame securing magnet assembly is mounted to the at least one magnet mounting member for releasably securing the apparatus to an outer surface of a tubular connection.
Claims8
An apparatus for guiding an anti-rotation key installation tool in a tubular connection, the apparatus comprising:
- a guide frame having at least one magnet mounting member;
- a tool positioning member coupled to the guide frame and having a first end and a second end;
- an installation tool positioning channel extending from the first end to the second end of the tool positioning member with an opening at the first end of the tool positioning member for accepting a portion of the anti-rotation key installation tool and an anti-rotation key recess located at the second end of the tool positioning member, the anti rotation key recess sized to house an anti-rotation key for installation in the tubular connection by the anti-rotation key installation tool;
- and
- at least one switchable frame securing magnet assembly mounted to the at least one magnet mounting member for releasably securing a face of the frame securing magnet assembly of the apparatus to an outer surface of the tubular connection, and wherein the tool positioning channel extends in a direction generally normal to the face of the frame securing magnet assembly so that when the face of the frame securing magnet assembly is releasably secured to the outer surface of the tubular connection, the anti-rotation key recess is proximate to the tubular connection and the second end of the tool positioning member faces in a direction generally away from the tubular connection.
