Abstract (en)
[origin: US2014216820A1] A drilling table for a drilling rig has an accommodation sleeve that can be rotated via a rotational drive for accommodation of a Kelly rod provided with driving contours. Coupling elements are disposed on the inside wall of the accommodation sleeve for engagement into the driving contours of the Kelly rod for transfer of torque and bias forces. Broken-out areas are introduced into the accommodation sleeve, through which areas the coupling elements that can be inserted from the outside are passed, to project into the sleeve interior. A drilling rig has such a drilling table.
