  • Patent number: 11125029
    Abstract: A rod positioning device for aligning a drilling rod with a rod string having complementary mating threads, comprising a base, an arm mounted to the base about a first rotation axis, and a rod-gripping device mounted on the arm. The arm is for displacement about the first rotation axis between a rod loading position and a rod alignment position. The rod-gripping device is for operating between a rod-gripping configuration and a rod-releasing configuration. The rod-gripping device comprises jaws for gripping the drilling rod while the rod-gripping device is in the rod-gripping configuration and the arm is in the rod loading position, and guiding elements mounted on the jaws, the guiding elements aligning the drilling rod with the rod string and enabling longitudinal displacement of the drilling rod to contact the rod string.

The liner is rotatably disposed within an outer shell mounted in the drill deck. A split retainer plate is attached to the outer shell and has an inwardly projecting flange around its inner periphery which is captured between a pair of radially outwardly projecting flanges around the outer periphery of the liner. The flanges permit limited lateral movement of the liner with respect to the outer shell, but prevent the liner from being removed axially from the shell. A plurality of shock absorbing cushion roller assemblies are mounted vertically in slotted cages between the liner and shell. The roller assemblies each include a shaft surrounded by a sleeve within a cushion coating bonded to the sleeve, with thrust washers between the ends of the sleeves and the cages.
