Abstract
Official abstract text for this publication.
A tubesheet anchor for suspending a tool from the underside of a heat exchanger tubesheet that inserts one end of two fingers into corresponding openings in the tubesheet and leverages one finger off the other to apply a frictional force to the sides of the tubesheet openings in which the fingers are inserted to clamp the fingers to the tubesheet.
First claim
Opening claim text (preview).
What is claimed is: 1. A tool having an actuator for gripping a tubesheet of a heat exchanger having a plurality of heat exchange tubes extending at least partially through thru-holes in the tubesheet, each of the heat exchange tubes having a central axis extending along a length thereof, the actuator comprising: a first elongated finger sized to have a first end of the first elongated finger inserted at least partially within a first of the thru-holes within the tubesheet; a se…
