A directional drill securing device and associated methods are shown. Securing devices and methods shown include a plurality of staking devices on a single lateral side of a directional drill. Using examples shown, a lower force is required to drive multiple staking devices than would be needed for a larger staking device of equivalent area.

A side saddle slingshot drilling rig includes a right substructure and a left substructure, the substructures positioned generally parallel and spaced apart from each other. The right substructure includes a right lower box and a first strut, the first strut pivotably coupled to the drill rig floor and pivotably coupled to the right lower box. The left substructure includes a left lower box and a second strut, the second strut pivotably coupled to the drill rig floor and pivotably coupled to the left lower box. The side saddle slingshot drilling rig also includes a drill rig floor, the drill rig floor including a V-door. The side of the drill rig floor has the V-door defining the V-door side of the drill rig floor, the V-door side of the drill rig floor parallel to the right substructure. The side saddle slingshot drilling rig further includes a mast, the mast including an open side defining a mast V-door side. The open side is oriented to face perpendicular to the right substructure. The mast is pivotably coupled to the drill rig floor by one or more mast pivot points and one or more lower mast attachment points, the mast being pivotable in a direction parallel to the V-door side of the drill rig floor or the mast being pivotable in a direction perpendicular to V-door side of the drill rig floor. The mast includes two or more subunits, wherein the two or more subunits are pinned together.

A drilling rig system includes a drilling rig that includes a mast, a pair of hydraulic pistons coupled to a pair of front legs of the mast and configured to apply a first force to the mast, the first force acting in a direction opposing a force generated by a weight of the mast, a plurality of raising lines coupled to a crown block of the mast and to a pair of rear legs of the mast opposite the front legs and configured to apply a second force to the mast, the second force acting in a direction opposing the force generated by the weight of the mast, and a drawworks assembly coupled to the plurality of raising lines and configured to apply a force acting away from the crown block of the mast to at least one of the plurality of raising lines to generate the second force.

The present disclosure relates to a modular drilling cellar configured to be arranged beneath a drill floor of a drilling rig. The cellar may have a housing for storing well head equipment and a drill floor support structure. The drill floor support structure may have a pair of support legs, each leg may have an extension portion, a column portion, and a bearing foot. Each of the extension portion and column portion may be configured to be arranged in a reading position and an operating position.

A linkage assembly for a drilling machine includes a first arm, a second arm, an actuation member, and a connector assembly. A first end of the first arm is pivotally coupled to a positioning member at a first pivot joint. A first end of the second arm is pivotally coupled to a feed table at a second pivot joint. A first end of the actuation member is pivotally coupled to the feed table at a third pivot joint. The connector assembly is fixedly coupled to a second end of the first arm, and pivotally coupled to a second end of the second arm and a second end of the actuation member. The linkage assembly is adapted to pivot the feed table relative to the positioning member about a pivot axis based on movement of the actuation member between an extended position and a retracted position.

A gripping device, rock drilling unit and method of gripping drilling tools is disclosed. The gripping device includes a frame and at least one elastic gripping element connected in a fluid-tight manner to the frame. The gripping element may be expanded by conveying pressurized fluid between surfaces of the frame and the gripping element, whereby the gripping element moves against surfaces of the drilling tool and generates friction forces and support.

A Ground drilling device having a drilling carriage and a sled movable back and forth on the drilling carriage, wherein at least one gear is present for the drive of the sled, whose rotary movement is transformed into a linear movement by means of a rack, wherein a force relieving pathway is provided to relieve the gear of a radially introduced force.
