STUCK THREADED MEMBER EXTRACTOR TOOL AND EXTRACTION METHODS

摘要

Disclosed is tool having a tapered first portion configured to translate a first rotational force to the stuck member, a second portion connecting with the first portion and configured to translate a second rotational force to the tapered first portion, a planar tip at an end of the first portion and perpendicular to a central axis passing through the first portion and the second portion, a plurality of left-handed splines extending laterally along the central axis from the tip toward the second portion, a driver engaged with the second portion and configured to receive a third rotational force from a mechanical manipulator, and a leak seal connected to the driver and configured to form a seal around the stuck member and at least a portion of the driver and prevent gases opposite the stuck member from escaping through an opening created by extraction of the stuck member.

主权项

1. A tool for extracting a stuck member, comprising:
a tapered first portion configured to translate a first rotational force to the stuck member; a second portion connecting with the first portion and configured to translate a second rotational force to the tapered first portion; a planar tip at an end of the first portion and perpendicular to a central axis passing through the first portion and the second portion; a plurality of left-handed splines extending laterally along the central axis from the tip toward the second portion; a driver engaged with the second portion and configured to receive a third rotational force from a mechanical manipulator; a leak seal connected to the driver and configured to form a seal around the stuck member and at least a portion of the driver and prevent gases opposite the stuck member from escaping through an opening created by extraction of the stuck member; and a gas capture port connecting with the leak seal.
