A drilling rig mobility system moves a drilling rig or similar structure in an oilfield or similar environment and includes independently controllable positioning shoes attaching to the drilling rig and controllable through separate and coordinated position control commands. Each positioning shoe may be individually addressed to reposition the drilling rig. Each positioning shoe includes a hydraulic actuator and wireless control circuitry. The hydraulic actuator provides vertical, horizontal and rotational force in response to wireless control signals for wireless position and control data and instructions with a remote wireless communications device. A cylinder stomper vertically elevates the hydraulic actuator and receives and transfers the vertical and rotational force. A foot assembly transfers the horizontal force from the hydraulic actuator. A positioning shoe cylinder stomper and positioning shoe traverse cylinder provide infinitely variable position control.

A system for compensating for a slope of a work surface while drilling holes in the work surface includes a leveling system, a rotary drill mechanism, a position sensor, an inclination sensor, and controller. The controller is configured to access coordinates of a desired map drill hole, determine current coordinates of a machine reference, and determine a current slope of the machine. A dynamic offset compensation is determined to compensate for movement of the rotary drill mechanism by the leveling system from a first position offset from the desired map drill hole to a second position aligned with the desired map drill hole, with the dynamic offset compensation being based upon the characteristics and the current slope of the machine. Upon the rotary drill mechanism being aligned with the first position, generating a leveling command to move the machine so that the rotary drill mechanism is aligned with the desired map drill hole.

A drill apparatus mounted to a vehicle; having a vehicle, a boom arm apparatus and a drilling apparatus, wherein a first end of the boom arm apparatus is attached to the vehicle and the drill apparatus is flex ably attached to a second end of the boom arm apparatus via a self aligning apparatus so that the drill apparatus is forced against a surface which is to be drilled via the boom arm apparatus, thus securing the stability of the drill apparatus against the drilling surface and the drill mast is self-aligned substantially perpendicular to the surface to be drilled.

A mining machine includes a base having two drive tracks configured to rest on a ground surface and to move the mining machine along a first direction. The drive tracks each have a length along the first direction between a front end of the drive track and a rear end of the drive track. The mining machine further includes a carbody that extends between the two drive tracks, a turntable coupled to the carbody that defines an axis of rotation, and a stabilizer appendage coupled to the carbody. The stabilizer appendage extends forward from the carbody along the first direction and includes a roller or plate to contact the ground surface and provide stabilizing support during a digging operation. The axis of rotation is positioned closer to the front end of the drive tracks than the rear end of the drive tracks.

A method includes drilling a first bore into a formation to a first depth, the bore having a bore wall and a first diameter that is sufficient to receive a casing pipe. A casing pipe is driven into the drill bore, the casing pipe having a binder on an exterior surface of the casing pipe that is configured to secure the casing pipe to the bore wall, the casing pipe being secured to an anchoring nut at a proximal end. The anchoring nut includes a gripping feature. An anchoring clamp of a drill rig is engaged with the gripping feature of the anchoring nut to thereby anchor the drill rig to the formation. The anchoring clamp includes a plurality of jaws that are movable toward and away from a central axis.

The present invention relates to a multi-functional drilling experiment platform, which consists of a gantry, a hydraulic cylinder, a power swivel and a platform base. The gantry mainly realizes the control of the drill string during the drilling-in process. In order to simulate the vertical well, the inclined well, and the horizontal well, the drilling machine needs to rotate between 0 and 90. The rotation of the gantry is realized by the extension and contraction of the hydraulic cylinder. The platform base is used to set up the gantry and the hydraulic cylinder, bearing the pulling, pressing and twisting loads of drilling experiments. Also, the platform base can move along the track to achieve different types of experiments. The multi-functional drilling experiment platform of the present invention realizes the load simulation experiment of the drilling machine at different angles using the gantry and the hydraulic cylinder.

A mast assembly for a mobile drilling machine may comprise: a mast frame including a back, a first side, and a second side, the first side and the second side diverging from the back to form an open front along substantially an entire length of the mast frame; a drill motor assembly movably attached to the mast frame, wherein the drill motor assembly is configured to rotate a drill pipe; and a drill drive assembly configured to drive the motor assembly up and down along a length of the mast frame, the drill drive assembly including: a sheave assembly comprising a plurality of sheaves, wherein the plurality of sheaves include a first sheave aligned generally parallel to the first side of the mast frame and a second sheave aligned generally parallel to the second side of the mast frame.

An adjustable drilling rig is provided for drilling and installation of foundational micropile matrices in difficult to access locations. A platform and separately adjustable legs are provided to level the platform. Arms and a crossbar mount to the legs, and each includes a bushing slidably mounted and moveable there along. A mast is slidably attached to the crossbar bushing through a mounting plate. The mast carries a drill head to which a drill will be attached. Various adjusters are mounted to bushings, mounting plate and other components of the adjustable drilling rig and are independently and selectively activated to adjust the drill head translationally along the X-, Y- and Z-axes and rotationally about the X- and Y-axes to achieve five degrees of freedom in five planes. The entire adjustable drilling rig is provided in two frames for easy transport to remote work sites and may be assembled without complex tools.

A mobile drilling rig is mountable on a separate drive chassis having running gear. A separate main frame may be having elongated members, each having outer end extensions and vertically adjustable support posts thereon. A slide chassis is slidable on one end of the main frame mounting a power plant, and a mast pivot support pivotally mounted on the other end of the main frame. An elongated mast has a drill head movable thereon, with the mast pivot support slidably mounting the mast thereon so that the mast may be pivoted between vertical and horizontal orientations thereon while being movable in lengthwise directions. The slide chassis, the mast and drill head are moved to positions improving the stability of the rig when traversing grades in an up or down hill direction.
