SWING MOUNTED FILL UP AND CIRCULATING TOOL

摘要

A mounting system (16) for a fill-up and circulating tool (36) on the rig hoisting system is disclosed. In the preferred embodiment, the tool (36) is supported on one of the bails (12,14) and is driven to rotate around the longitudinal axis of one of the bails (12,14). A combined vertical and rotational movement is imparted by the mounting system to allow the fill-up and circulating tool (36) to be raised and swung out from the bails (12,14) to allow normal drilling or tripping. In the other position it can be swung over the tubular (32) and lowered for sealing contact to allow fluids to pass in both directions to or from a pumping and storage system on the rig.
