摘要： A machine comprising a frame supported on a movable carrier. A first actuator is adapted to actuate a boom coupled to the frame. A first sensor generates signals indicative of a spatial orientation of the boom. At least one second actuator actuates a drilling work device coupled to the boom. A second sensor generates signals indicative of a spatial orientation of the drilling work device. A controller receives signals indicative of the spatial orientation of the boom and the drilling work device and actuates at least one of the first actuator and the second actuator through predetermined sequential steps to automatically position the machine in a default configuration. The controller further receives signals indicative of data corresponding to at least one drilling hole and automatically positions the machine in an operating configuration.

摘要： 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.

摘要： A horizontal directional drilling machine includes a drill string rotational drive unit having an output member configured to connect with and selectively drive rotation of a drill string, the rotational drive unit including a hydraulic motor. A hydraulic circuit has a configuration that puts the motor in a drive mode to apply torque and a second configuration that puts the motor in a freewheel mode disabled from applying torque. The hydraulic circuit includes a first fluid flow path for connecting the hydraulic motor through a first rotary ball valve to one of an inlet side and an outlet side of a drive pump, and a second fluid flow path for selectively connecting the hydraulic motor through a second rotary ball valve to the other side of the drive pump. In the first configuration, there is no pressure drop across the first and second rotary ball valves.

摘要： A downhole drilling apparatus may comprise a rotatable body with fixed cutting elements protruding from an exterior thereof. To form a subterranean borehole, the fixed cutting elements, spaced at a constant radius from a rotational axis of the body, may degrade an earthen formation as the body rotates. The body may also have a rotatable cutting element protruding from its exterior. To remove material from an interior wall of the borehole, the rotatable cutting element may be positioned in a first rotational orientation wherein it extends radially beyond the constant radius of the fixed cutting elements. An amount of material being removed may be altered by rotating the rotatable cutting element into a second rotational orientation wherein it remains radially within the constant radius.

摘要： An apparatus, a method for positioning a rock drilling, and a rock drilling rig is provided. The rock drilling rig includes a mobile drilling platform and a drilling mast connected to the drilling platform. The drilling platform is levelled vertically before initiating drilling. The apparatus determines the needed vertical levelling requirement. The levelling causes displacement of a drilling tool line passing through a drilling tool. The apparatus estimates the displacement and provides aid for the operator to position the drilling platform in order to compensate for the estimated displacement distance.

摘要： 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.

摘要： A directional drill vice and associated methods are shown. A directional drill and associated methods are also shown. Examples of directional drill stem configurations include gripping jaws configured with a common jaw pivot. Examples of directional drill stem configurations also include a slot in a vice frame to allow lateral insertion of a drill stem segment.
