Abstract:
A guide tube for continuous rod has a sections pivotably connected together by at least one translatable pivot. The tube connects to a rig at a fixed pivot and is initially folded on the rig for transport. To unfold and raise the tube for operation, a rig operator pivots a support rod pivotably connected to the tube away from the rig using a rope. This pivoting support rod moves the attachment point of a winchline extending from the rig to the rod beyond the tube's fixed pivot. Also, the pivoting rod tensions a sling having a fixed length that extends from the rod to the tube's translatable pivot. In this way, the winchline can be tensioned without the need for rig operators to perform a substantial amount of manual labor as conventionally done. Once the outer sections of the guide tube are lowered to the ground, the entire guide tube can be unfolded and raised with the tensioned winchline.
