Abstract
This invention relates to a manually-operated mechanism for inserting and removing flow measurement probes and the like from a pipeline carrying a flowing fluid, such mechanism being characterized by a hanger subassembly including a yoke mounted atop the probe for movement therewith externally of the pipe along with a pair of threaded rods suspended non-rotatably from the yoke and which parallel one another as well as the longitudinal axis of the probe but on opposite sides thereof, a drive subassembly supported in fixed position beneath the yoke and including a common drive shaft along with a pair of worm gear trains each containing a worm gear threaded onto one of the threaded rods, such drive subassembly operatively interconnecting the shaft and the two threaded rods for simultaneously and synchronously raising or lowering the latter, and a handcrank for turning the drive shaft.
