摘要

An apparatus for gripping a support member is described. The apparatus comprises a tubular clamp, the tubular clamp defining a throughbore adapted to receive a support member therethrough, a first apparatus member adapted to engage a first portion of an external surface of the tubular clamp, and a second apparatus member adapted to engage a second portion of the external surface of the tubular clamp. Relative movement of the first apparatus member with respect to the tubular damp in a first direction results in a deflection of a section of a first end of the tubular clamp into the clamp throughbore and relative movement of the second apparatus member in a second direction, opposite the first direction, with respect to the tubular clamp results in a deflection of a section of a second end of the tubular clamp into the clamp throughbore.

1. A downhole apparatus for gripping a support member, the apparatus comprising:
a tubular clamp, the tubular clamp defining a throughbore adapted to receive a support member therethrough; a first apparatus member adapted to engage a first portion of an external surface of the tubular clamp, wherein the first apparatus member is adapted to slide over the first portion of the clamp external surface; a second apparatus member adapted to engage a second portion of the external surface of the tubular clamp, wherein the second apparatus member is adapted to slide over the second portion of the clamp external surface; and a resilient element wherein the resilient element is adapted to apply a force to the first apparatus member to move the first apparatus member with respect to the tubular clamp, wherein the tubular clamp comprises a first support member engaging surface adjacent a first end of the tubular clamp and a second support member engaging surface adjacent a second end of the tubular clamp, the first support member engaging surface comprising first end fingers and the second support member engaging surface comprising second end fingers, and wherein the apparatus is adapted to increase the grip on the support member if a pull is applied to the support member from either direction.
