20090053013 | PORTABLE DRILL PIPE HANDLING APPARATUS FOR USE WITH OIL AND GAS WELL DRILLING RIGS - A pipe handling apparatus transfers successive lengths of drill pipe that are stored in a generally horizontal position on a pipe rack, to an elevated position on the rig deck of an oil and gas well drill rig. An elongated frame includes a base section with a folding section that can be inclined. Both the base and folding sections provide toothed racks. A trestle section travels from the base section toward the inclined section. Pinion gears at opposed end portions of the trestle section engage the toothed racks of the base and folding sections. The trestle section gradually increases in inclination as its front end portion travels toward and up hoisting rails of the inclined folding section. While the rear end of the trestle section remains on the base section, the front end portion of the trestle section climbs the toothed racks of the inclined rails. | 02-26-2009 |
20090053014 | APPARATUS FOR AN AUTOMATIC CASING STABBING ARM - The apparatus for an automated drill pipe casing stabbing arm includes a telescopic tube assembly, a movable roller bracket assembly, a movable arm assembly, a mounting assembly, an apparatus actuator, and a PLC portable remote control device. An actuator mechanism positions the gripping arm assembly and the roller bracket assemble relative to one another in order to capture and grip the casing therebetween to support and grip the casing on the circumference thereof from opposing diametric sides. The automated stabbing arm is installed on a rig's mast or derrick. In a working position, the apparatus is oriented horizontally to provide radial support and guidance to the casing. A rig worker on the rig floor controls the apparatus by means of the portable remote control device. | 02-26-2009 |
20100068006 | CATWALK FOR A DRILLING RIG - A pipe handling catwalk comprising: a deck including an upper surface, a first end, an opposite end and a tubular support surface on the upper surface, the tubular support surface being elongate and extending between the first end and the opposite end; a deck guide including a wall extending up from the deck upper surface and drivable along tubular support surface of the deck; a ramp mounted on the deck adjacent its first end and positionable extending at an angle from the deck; a carrier connected to the ramp to remain on the ramp and being moveable such that an end thereof can be lifted away from the ramp to reduce the inclination of the carrier relative to the angle of the ramp, the carrier including an upper surface and a tubular retaining surface thereon extending along the carrier substantially in line with the tubular support surface of the deck; and a carrier guide including an upstanding tubular engaging surface extending up from the carrier upper surface and drivable along tubular retaining surface of the carrier. | 03-18-2010 |
20100111646 | Method and apparatus for handling pipe - An apparatus and method for handling pipe includes an elongate frame structure for mounting on a ground surface, in which a carriage unit is mounted on the frame structure and is operable for selective and reciprocal shifting along the frame structure. A boom member mounted on the carriage unit is operable for selected pivotal movement relative to the carriage unit, and a plane generally parallel to the boom member's longitudinal axis, about a generally horizontal pivot axis oriented transverse to the direction of shifting of the carriage unit along the frame structure. An elongate pipe carrier mounted on the boom member as dimensioned for receiving pipe so that the pipe's longitudinal axis is substantially parallel to the longitudinal axis of the boom member and the pipe member, wherein the pipe carrier is operable for selective pivotal movement about its longitudinal axis. | 05-06-2010 |
20110070054 | APPARATUS AND METHOD FOR HANDLING TUBULARS - An apparatus for use in delivering tubulars to an elevated work area is described. A slideway for receiving a tubular is mounted on the leading end of an extendable carriage. The opposing end of the carriage is pivotally fixed to a frame assembly. Extension of the carriage drives the leading end towards a work area. A carriage support ramp receives the leading end of the carriage as it is extended, and guides the leading end towards the elevated work area for discharge of the tubular from the slideway. | 03-24-2011 |
20120243965 | Cartridge Tubular Handling System - A cartridge of tubulars may be removably positioned with a carriage, and the carriage may move the cartridge transversely, vertically, and/or rotationally to roll tubulars on an adjacent tubular receiving member using only gravity from a selected tier of tubulars without human contact. A single trolley disposed with the tubular receiving member both pushes and pulls tubulars toward or away from the drilling deck. | 09-27-2012 |
20130089393 | Tubular Positioning System - A system for delivering a downhole tubular from a rack at an oilfield surface to a rig floor thereat. The system includes a trough for accommodating the tubular that is slidably engaged with a lift frame in a sledded fashion. Thus, for delivery of the tubular, the trough may be sleddingly extended from the lift frame. That is, as opposed to a roller type of coupling between the trough and tubular, a sledded coupling is utilized that may require comparatively less maintenance and mobilization time. This may be particularly the case where lighter weight tubulars of less than about 1,000 lbs., preferably under about 500 lbs., are being delivered. | 04-11-2013 |
20130336747 | PIPE HANDLING APPARATUS AND METHOD - Equipment for moving tubular members from a storage rack to an elevated platform floor is disclosed. A base-mounted articulated support structure has an arcuate trough mounted on top thereof. Loading arms are secured to a side of the pivotal trough for picking up one tubular member from the rack and moving to the platform floor. Unloading arms detachably securable to the trough facilitate movement of the tubular members from the platform floor onto the rack. | 12-19-2013 |
20140030046 | PIPE HANDLING APPARATUS - A pipe handling apparatus includes a support base extending longitudinally and disposable proximate a pipe handling rig. A lifting base is movably attached to the support base. The apparatus has means for moving the lifting base longitudinally along the support base, an intermediate support frame coupled to the lifting base and a vertical lifting device coupled between the intermediate support frame and the lifting base. The vertical lifting device is configured such that through an entire lift motion thereof, the intermediate support frame remains in a same plane as the lifting base. A pipe handling channel is pivotally coupled at one end to the intermediate support frame. Means for elevating the other end of the pipe handling channel are coupled to the intermediate support frame and the pipe handling channel. | 01-30-2014 |
20140286732 | HYDRAULIC CABLE-SKATE DRIVE SYSTEM FOR CATWALK - A drive system for a catwalk skate that uses a hydraulic skate-cable drive system. The system includes two counteracting hydraulic cylinders, each with a sheave connected to the cylinder rods, and a cable that winds around each of the sheaves and connects to both ends of the skate. | 09-25-2014 |
