B66C 11/18

Abstract:

A system for moving a bridge crane includes a first drive and a second drive coupled to a support structure, a first sheave and a second sheave coupled to the support structure, and third sheaves coupled to a beam movable in a first axis. The system includes a first line coupled to the first drive, the first sheave, the second sheave, and one or more of the third sheaves. The first line is coupled to a gripping assembly that is coupled to the beam and movable in a second axis. The system includes a second line coupled to the second drive, the first sheave, the second sheave, and the third sheaves. The second line is coupled to the gripping assembly. Rotating the first and second drives causes the beam and the gripping assembly to move in the first axis and/or the gripping assembly to move in the second axis.

Abstract:

Apparatus and methods for metering fluid to a fluid actuator. An example apparatus may include a hydraulic actuator and a fluid chamber. The fluid chamber may include a piston slidably movable between first and second ends of the fluid chamber and dividing the chamber into first and second chamber portions, a first port extending into the first chamber portion, and a second port extending into the second chamber portion. The apparatus may further include a hydraulic directional control valve operable to direct a fluid from a fluid source into one of the first and second ports to cause a volume of fluid to be discharged out of the other of the first and second ports into the hydraulic actuator to actuate the hydraulic actuator by a distance corresponding to the volume of fluid received by the hydraulic actuator.

Abstract:

The present invention discloses a drill rig relocation system. Lift frames are provided as add-ons to existing drill rigs, or as integral openings within the length of the base boxes. A lift cylinder and bearing mat assembly is connected beneath the lift frame or base boxes. Each bearing mat assembly has a slew drive for controlled directional rotation. A torque arrest system allows vertical movement of the torque reaction point as the substructure is elevated to control the orientation and magnitude of forces. In one embodiment, the drill rig is supported on linear sleeve bearings slideably mounted in the bearing mat assemblies. Translation cylinders on the bearing mats expand to move the drill rig by translating the linear sleeve bearings along the shafts.
