  • Patent number: 11187049
    Abstract: A fingerboard has a first portion configured to receive a first pipe and a second portion configured to receive a second pipe. The fingerboard includes a fixed section and a movable section, each having fingers and latches that define a pipe receiving space. The pipe receiving space of the fixed section is sized for drill pipe while the pipe receiving space of the movable section may be the same size as the pipe receiving space of the fixed section or a different size than the pipe receiving space of the fixed section. The movable section has a first and a second pipe receiving spaces. The second pipe receiving space may be larger than the first pipe receiving space. A hinge moves the movable section to selectively locate the first pipe receiving portion and the second pipe receiving portion adjacent to the fixed section. A mover, such as a hydraulic cylinder, is affixed to the movable section.

  • Publication number: 20210324689
    Abstract: A system for handling a tubular member includes a gripping assembly configured to grip the tubular member. The system also includes a horizontal actuator configured to move the gripping assembly and the tubular member horizontally between a rack and alignment with a wellbore while the tubular member is gripped by the gripping assembly. The system also includes a vertical actuator coupled to the gripping assembly, the horizontal actuator, or both. The vertical actuator is configured to move the gripping assembly and the tubular member vertically while the tubular member is gripped by the gripping assembly and in alignment with the wellbore. The system also includes a rotating assembly coupled to the gripping assembly and configured to rotate the tubular member while the tubular member is gripped by the gripping assembly and in alignment with the wellbore.

  • Patent number: 11097929
    Abstract: Embodiments of a top-mounted hoisting system include a single-layer winch drum located at an uppermost end of a derrick or drilling mast, a drill string handling tool, and one or more drill lines extending from the single layer winch drum to the drill string handling tool. The drill string handling tool may be a top drive. When the drill line is connected directly to the lifted load, the drill line experiences far less load cycles than when the line runs through crown and travelling blocks. If the drum diameter is large enough, cut-and-slip operations may be eliminated, and the drill line may be replaced at longer time intervals. Embodiments provide for lower weight and may provide lower cost as a result. The top-mounted drum does not take up any space on the drill floor and less total length of drill line is also required than if the drum was floor-mounted.

  • Patent number: 4582133
    Abstract: A pipe handling assembly in connection with an oil derrick comprises two pivotable and vertically movable arms having a grab head in the form of a U-shaped claw intended for transporting a stand of pipe, a drill collar or the like from the well center to a rack, and vice versa. The grab head on one arm, preferably the lower arm, is subdivided vertically into a lower U-shaped member fixedly connected to the arm via a housing and an upper U-shaped member rotatably relative to the lower member and provided with locking means for retaining the pipe, drill collar or the like. The two members are provided with rotation means intended to bring the upper, rotatable member from an arbitrary angular position into a locked position in which its claw aperture is in alignment with the claw aperture of the lower member.
