Abstract: A drilling rig assembly and methods of assembling a drilling rig are described. The drilling rig assembly can include a mast, a traveling assembly coupled to the mast, and a racking board configured to be removably coupled to the traveling assembly and removably coupled to the mast.

Abstract: A method for connecting drill pipe to a drillstring in a wellbore includes positioning a lower section of drill pipe within a rotary slips and setting the rotary slips. The method includes positioning an upper section of drill pipe over a lower section of drill pipe and signaling an iron roughneck to extend toward a joint of the lower section of drill pipe and upper section of drill pipe. The method includes raising the iron roughneck to a height such that opposing tongs are positioned above and below the joint between the upper section of drill pipe and the lower section of drill pipe, spinning the upper section of drill pipe into the lower section of drill pipe, clamping onto the lower section of drill pipe with the tongs of the iron roughneck, and spinning the upper section of drill pipe into the lower section of drill pipe.

Abstract: A drill rig may include a motor connected to a piston-diaphragm pump configured to: apply a force to a fluid in a cylinder of the piston-diaphragm pump by moving a piston in the cylinder, the fluid filling a void inside the cylinder between a head of the piston and one side of a diaphragm; transfer the force from the fluid across the diaphragm to a drilling mud by flexing the diaphragm, where the drilling mud is separated from the first fluid; and cause a flowrate of the drilling mud through a value connected to the cylinder via a high-pressure piping system into the borehole. The drill rig may direct the mud through a kelly and a pipe to a bottom of the wellbore, force the mud through nozzles located near a bit, rotate the bit, and returning the mud through an annulus to the surface.

Abstract: A method assembling a drilling rig is described. The method includes providing a mast of a drilling rig. The mast can include a racking board attached at a first height above a rig floor. The method further includes providing a detachable diving board; aligning the diving board with a traveling assembly of the rig, with one or more rails of the mast, or with a dolly removably coupled to the traveling assembly; removably coupling the diving board to the traveling assembly or the dolly; raising the diving board to the first height, The diving board can be located in a middle portion of the racking board in the first height. Further, the diving board can b removably coupled to the racking board; and decoupled from the traveling assembly or the dolly.

Abstract: A rotation brake for stopping rotation of a spindle assembly on a horizontal directional drill. The rotation brake comprises a brake lock that is actuated by a cylinder and spring to interact with a non-rotating brake cap and a rotating pinion, thereby stopping rotation of the pinion. The brake lock is removed from the pinion by applying pressurized fluid to a cylinder such that a cylinder rod moves the brake lock out of a cavity between the brake cap and the pinion. Upon removing fluid pressure from the cylinder, a compressed spring moves the brake lock back to into the cavity, preventing rotation.
