Abstract
A combination hydraulic pipe handler and power swivel for providing services normally requiring two machines, two hydraulic systems, two engines, two spaces at a rig site, and two costs to the user. Now only one machine is required. The combination hydraulic pipe handler and power swivel can pick up tubulars, present tubulars safely to the rig floor at an adjustable angle, and provide a tilting power swivel which tilts to the same adjustable angle allowing the rig operator to threadably engage tubulars and lift the tubulars to vertical. Tailing of tubulars with a rope and manpower is not required, thus the operation is much safer than normal.
Claims5
A combination hydraulic pipe handler and power swivel comprising:
- a platform comprising a plurality of wheels, a plurality of outriggers, and a towing hitch;
- a power swivel comprising a tilt mechanism, the tilt mechanism further comprising:
- a tilt cylinder assembly comprising a hydraulically controlled extension;
- a tilt cylinder rod configured for setting max of tilt;
- and
- a tilt plate configured to support the tilt cylinder assembly, and setting the power swivel to a repetitive vertical position;
- a pipe loader further comprising a plurality of pipe handling arms configured to allow tubulars to roll toward or away from a pipe handling mechanism centerline of the combination hydraulic pipe handler and power swivel;
- a pipe handler comprising:
- a catwalk or a pipe trough with a pipe handling centerline;
- and
- a transport mechanism configured to longitudinally transfer tubulars from a pipe rack centerline to a rig floor;
- a hose reel comprising a maximum of four hoses for pipe handling functions;
- a hydraulic pump;
- an operator station for controlling the pipe loader and the pipe handler;
- and
- a second operator station for controlling the power swivel;
- wherein the power swivel is in mechanical communication with the hydraulic pump and each of the four hoses on the hose reel, and wherein each of the set of hoses is configured to be in hydraulic communication with the power swivel.
