APPARATUS FOR CAPTURING AXIAL FORCE ON AN INNER DRIVE MEMBER
A spindle with a mechanism for transferring axial force from an inner drive assembly to an outer drive assembly. The spindle's inner drive shaft is connected to an inner member of a dual-rod pipe by a drive rod having a sliding sleeve. The sleeve is fixed rotationally with the drive shaft, but not axially. When axial force drives the drive rod toward the drive member of the spindle, the sleeve contacts a stop member which is paired to the outer drive assembly. The stop member may be a pair of dowel pins. Axial force is thereby transferred from the inner member to the outer member, allowing such forces to be absorbed by the outer member's larger drive components.

A track tensioning system configured to automatically adjust and maintain tension on an endless track used in a track assembly. Tension is applied to the track by pressure applied by one of the rollers included in the track assembly. The roller is movable relative to the other components of the track assembly using a linear actuator. Power is supplied to the linear actuator via a power source. The power source is configured to regulate the amount of power supplied to the linear actuator to maintain the track assembly at a desired track tension.
A cable gripping assembly. The gripping assembly has two jaw assemblies for gripping and pulling a cable. Each jaw assembly has a jaw block with a tapered cavity, and a jaw subassembly which fits within the tapered cavity to grip a cable when frictional forces, caused by a hydraulic cylinder or other actuator, force the jaws into the tapered cavity. The jaw subassembly has a guide plate, which carries pins affixed to the jaws. The guide plate is ordinarily allowed to move the pins along angled slots in a jaw plate. However, when actuated by a plunger, the guide plate and pins are forced to a widest point of the angled slots, maintaining the jaws in an open position, allowing for easy removal of the strand from the gripping assembly.

A tension link for use in downhole operations. The tension link has a link body connecting two features, such as a backreamer and product pipe, which are towed through a borehole. The tension link has electronics which can monitor the tension in the link body. The electronics may include a Bluetooth radio or similar device, which uses a power source to send a low power signal including the tension data to a beacon, which is located in a separate cavity of the tension link. The beacon encodes received information about tension onto a stronger electromagnetic field. This electromagnetic field may, in turn, be used to power the electronics. No direct link between the electronics and the beacon exists, and the beacon may be used in other downhole operations other than tension monitoring, such as directional drilling. The electromagnetic field signal is detected at a receiving antenna at an uphole location.

A track frame with a tensioning system. The track frame has a first section, connected to a number of rollers, including a front roller, and a nested second section attached to a rear roller. The orientation of the first and second sections, and thus the tension on a track, is adjusted by a grease cylinder. The track frame has an indicator window, which displays the position of a plate indicative of tension on the track. When the plate is in alignment with the window, tension is appropriate. In addition, the position of the indicator window within a larger window in the first section is indicative of the stroke of the grease cylinder, which may indicate the need to replace the track.
A calibration method for calibrating an underground beacon and tracker system for use with horizontal directional drilling. The beacon emits a magnetic field, which is received at an above-ground receiving antenna. The antenna is used to locate front and rear null points in the emitted field. The vertical and horizontal offset between the null points is determined to locate the beacon. Then, the magnetic field strength is determined at one of the null points. This value may be used to calculate or update a calibration constant. The calibration constant is then used in subsequent locating step while the characteristics of the underground environment surrounding the beacon remain similar.

An optimizable beacon and method of using the same. The beacon has an onboard power source with a finite capacity. The system uses a capacitor bank to adjust the capacitance of the beacon, thereby maximizing the signal provided considering conditions, rather than simply using a theoretical value. With the specified capacitance being used, the beacon may be optimized in both a high and low power mode by driving the current to ensure the measured power is greater than or equal to a target. The system may also have a motion sensor to toggle the power off, or to a low-power mode, when the beacon is moving, and location measurements are not taking place. The optimization process may also consider the chemistry of the battery being utilized.

A guidance system for remotely guiding a work machine along a virtual path. The system uses a vision system to capture image data representative of areas surrounding the work machine. The image data is used to produce a spatial map. Analysis of image data allows the work machine's then-current position to be represented on the spatial map. A virtual path extending from the work machine's position is next added to the spatial map. The virtual path may be generated in response to external input provided at the display showing an image of the spatial map. Using continuously-updated image data, the work machine is driven toward the virtual path. During operation, the actual path of the work machine is compared to the virtual path. If any deviation between the paths is detected, the trajectory of the work machine is automatically adjusted.

Apparatus for capturing axial force on an inner drive member
A spindle with a mechanism for transferring axial force from an inner drive assembly to an outer drive assembly. The spindle's inner drive shaft is connected to an inner member of a dual-rod pipe by a drive rod having a sliding sleeve. The sleeve is fixed rotationally with the drive shaft, but not axially. When axial force drives the drive rod toward the drive member of the spindle, the sleeve contacts a stop member which is paired to the outer drive assembly. The stop member may be a pair of dowel pins. Axial force is thereby transferred from the inner member to the outer member, allowing such forces to be absorbed by the outer member's larger drive components.

The tracking device is registrable with a rover such that the antenna array may be moved by the rover in response to the magnetic field. A processor onboard the tracking device may communicate commands to the rover to either maintain its position relative to the underground object, or move to a location where the magnetic field can be measured.
A pipe shuttle for moving a pipe segment from an operating position to a pipe box. The pipe shuttle has a pair of gripper arms flanking a cradle. The cradle has a spring-loaded pad that has a concave surface for holding a pipe segment. As the pipe shuttle moves from underneath a pipe box to near a cradle, rollers are positioned to engage a guide plate. When the shuttle is underneath the pipe box, the rollers engage the guide plate to keep the cradle open. When moved towards an operating position, the rollers no longer engage the guide plate and cause grippers to close on the pipe segment. The spring-loaded pad allows the pipe shuttle to be moved relative to the pipe segment when the pipe segment is in its operating position.
A system for preventing an engine included in a work machine from restarting, after the work machine is tipped over. A sensor included in the work machine is configured to detect a tipping incident. If a tipping incident is detected, the sensor sends out a signal configured to shut down the engine and a tilt signal configured to prevent the engine from restarting. The engine is only restarted if certain steps are undertaken by an operator and a reset switch is activated.
A bearing assembly having independently rotatable concentric inner and outer tubes. A bearing chamber containing multiple bearings is disposed between the tubes, allowing thrust but not rotation to be transferred between them. The bearing chamber is sealed from the inside of the inner tube. To prevent high pressure fluid from leaking from the inner tube to an exterior of the tool through the bearing chamber, damaging components, a flow path is formed. An annular piston responds to high pressure within the bearing chamber and the inner tube, opening a flow path from the inner tube to the environment.
A replaceable tooth assembly. A number of tooth assemblies are provided round the periphery of a microtrenching blade. The assemblies include a cartridge, usually welded to the periphery of the microtrenching blade, and a tooth, which has a projection or flange shaped to fit within a cavity formed in the cartridge. The cartridge and projection each have a transverse hole formed in them, which, when aligned, form a continuous passage for placement of a removable pin which is used to join the cartridge to the tooth body. The cartridge may also have a more radially-aligned channel which intersects the cavity, which a rubber shim may be placed in. Such a shim reduces the relative vibration between the tooth and cartridge, improving life and reducing wear.

Augmented reality system for use in horizontal directional drilling operations
A system for tracking and steering a downhole tool using an augmented reality device. A tracker tracks the location of a downhole tool as it moves underground and transmits data to the device, while one or more sensors measure a position and orientation of the device. The device analyzes the data received from the tracker and the sensors and generates a virtual image of the downhole tool. The virtual image is displayed on the device at its detected location relative to the ground surface and relative to the position of the device. The position of the displayed virtual image is modified in response to updated information from the tracker or the sensors. Virtual images representing various parameters of the drilling operation are also displayed on the device in juxtaposition with the virtual image of the downhole tool.

A method of handling pipe segments during makeup and breakout of a drill string. The method uses a hydraulic circuit, which provides fluid to a motor or motors for translating a drill pipe segment. The drill pipe segment is supported by a carriage, which places the segment next to a drill string for addition thereto. Hydraulic pressure within the circuit is monitored to determine if a pressure fluctuation exists. If so, the translation speed is adjusted by modifying the hydraulic fluid flow to the motors. Sensors may be utilized to determine whether or not the system is in a “transition zone” and therefore ready for pressure monitoring for makeup and breakout functions.
A hydraulic control system for use with a work machine. The work machine has a platform which supports an operator. When the operator is not on the platform, the platform moves into a first position, causing a signal generator to send a signal to a controller. The controller is configured to limit the hydraulic flow to the ground drive motor when the platform is in the first position. The controller may directly reduce operation of the engine, or may adjust a valve which diverts a portion of hydraulic flow. The limitation may be overridden when desired by the operator.
A system for connecting a drill bit and pipe puller to a drill string. The system includes a downhole tool having an internal cavity and a through-hole in its wall. A coupler may be slidingly received in the cavity and connected using one or more fasteners which interconnect a groove in the coupler to the wall of the downhole tool. Fasteners used may be screws or bolts interconnecting the wall of the tool with radial holes in the coupler. Alternatively, bolts may interconnect the wall with a circumferential groove on the coupler. A drill bit may be threaded into the coupler. The coupler allows drill bits and other tools to be connected and disconnected from a downhole tool without unthreading the drill bit.

A calibration method for calibrating an underground beacon and tracker system for use with horizontal directional drilling. The beacon emits a magnetic field, which is received at an above-ground receiving antenna. The antenna is used to locate front and rear null points in the emitted field. The vertical and horizontal offset between the null points is determined to locate the beacon. Then, the magnetic field strength is determined at one of the null points. This value may be used to calculate or update a calibration constant. The calibration constant is then used in subsequent locating step while the characteristics of the underground environment surrounding the beacon remain similar.

At each of its ends, the duct opens at one of the plates. Air enters the fan from through a central opening formed in one of the plates, moves to a medial zone between the plates, and exits the fan at the medial zone's unwalled periphery. Air also crosses the fan by way of the ducts formed within each blade.
A system for monitoring installation of a utility product pipe within an underground borehole and detecting any issues with the installation process. The system utilizes one or more sensors to measure a parameter concerning the product pipe as the product pipe is pulled into the borehole, and one or more sensors to measure a parameter concerning the drill string as the drill string is pulled out of the borehole. The measured parameters are compared and analyzed to determine if any damage is likely to occur to the product pipe if the installation operation is not stopped and any issues remedied prior to continuing operation.
A wellbore gas separator having a pair of helical ramps. The separator ingests a liquid-gas solution, and a pump draws the solution into a first course between the pair of ramps. As centrifugal force is imparted upon the solution prior to the pump inlet, gas is forced out of solution. The liquid portions of the solution may fall into a dead space prior to the pump inlet. Gaseous portions enter into a second course between the pair of ramps and escapes, unimpeded, up the separator before being released into an annulus of a wellbore.
A machine for extracting a ductile pipe. The machine has a vise which can grip the pipe, and a wire clamp. Each of the wire clamp and vise are supported on a carriage which is movable relative to a frame. This enables the vise to grip and pull the ductile pipe. Additionally, a wire strand may be disposed through the pipe from a far end to the end at which the machine is placed. The wire clamp allows the machine to pre-stress the strand to improve the extraction of the ductile pipe.
A cruise control system for work machines. The system comprises one or more levers for controlling the velocity of the work machine and one or more magnet assemblies. The magnet assemblies comprise means of overcoming the neutral bias of a control lever so that the velocity of the work machine may be maintained without manual input from the operator. The magnets may act directly upon a control lever or a surface adjacent a control lever. Additional controls may be employed to set a maximum cruising speed for the work machine when cruise control is engaged.

A method for breaking the friction between a buried pipe section and its surrounding soil. A linear actuator or a pneumatic impact mole pushes on one end of the pipe section while a pipe extractor pulls on the opposing end of the pipe section. In an alternative embodiment, a device is used to excite the pipe section's natural vibrational frequency while a pipe extractor pulls on one end of the pipe section. After the friction between the pipe section and its surrounding soil is broken, the pipe extractor may remove the pipe section from its borehole. In another embodiment, the pipe section may be cut into smaller sections and each section may be individually removed from the ground using a pipe extractor. Alternatively, the smaller pipe sections may be individually loosened from the surrounding soil and then rejoined before being removed from the ground by a pipe extractor.
A magnetic coupler for inducing a signal on a buried utility wire. The coupler has two elongated jaws, each extending along a separate longitudinal axis. The jaws are attached at a hinge. The jaws may be placed about an exposed portion of the utility wire. A signal generate provides a signal which is emitted from a transmitter in each of the jaws. The signals emitted from each jaw are antiphase to one another, such that they are additive to a utility wire disposed between the jaws but out of phase with respect to any utility not between the jaws. The signal is thus induced on the utility wire and can be detected as emitted from its below ground length by a conventional locator.

Apparatus for capturing axial force on an inner drive member
A spindle with a mechanism for transferring axial force from an inner drive assembly to an outer drive assembly. The spindle's inner drive shaft is connected to an inner member of a dual-rod pipe by a drive rod having a sliding sleeve. The sleeve is fixed rotationally with the drive shaft, but not axially. When axial force drives the drive rod toward the drive member of the spindle, the sleeve contacts a stop member which is paired to the outer drive assembly. The stop member may be a pair of dowel pins. Axial force is thereby transferred from the inner member to the outer member, allowing such forces to be absorbed by the outer member's larger drive components.

An optimizable beacon and method of using the same. The beacon has an onboard power source with a finite capacity. The system uses a capacitor bank to adjust the capacitance of the beacon, thereby maximizing the signal provided considering conditions, rather than simply using a theoretical value. With the specified capacitance being used, the beacon may be optimized in both a high and low power mode by driving the current to ensure the measured power is greater than or equal to a target. The system may also have a motion sensor to toggle the power off, or to a low-power mode, when the beacon is moving, and location measurements are not taking place. The optimization process may also consider the chemistry of the battery being utilized.

A check valve assembly disposed within a pipe joint. The valve assembly is bounded by a pin end on one side and a liner tube on the other. In a first flow condition, a ball is forced away from the pin end and toward a stop member. The stop member has a geometry to allow fluid flow around the ball and through passageways within the stop when in the first flow condition. In a second flow condition, opposite the first flow condition, the ball is forced toward a tapered seat on the pin end, restricting fluid flow in the second flow condition.
A pipe assembly has a hollow inner member nested within a hollow outer member. A series of pipe assemblies are connected end-to-end to form a dual-member drill string useful in horizontal directional drilling operations. The drill string has mutually exclusive first and second fluid paths. Fluid seals, interposed between adjacent inner members of the string, isolate the first fluid path from the second fluid path. Compressed air is delivered into the first fluid path from above ground level, and routed to an underground boring tool. The expelled air and spoils are returned to above ground level by way of the second fluid path. One or more baffle elements are supported on the drill string adjacent the boring tool. The baffle elements are configured to prevent compressed air and spoils from flowing between the walls of the borehole and the drill string.

Tension is applied to the track by pressure applied by one of the rollers included in the track assembly. The roller is movable relative to the other components of the track assembly using a linear actuator. Power is supplied to the linear actuator via a power source. The power source is configured to regulate the amount of power supplied to the linear actuator to maintain the track assembly at a desired track tension.
An antenna arrangement. The arrangement uses four conductive loops, each within a distinct plane from the other conductive loops. The four conductive loops have a common center point. Each loop is within a dipole magnetic field, and detects a component thereof. By balancing the signals received between matched pairs of the conductive loops, the difference between the signals can be used to guide the antenna arrangement to a null point—that is—a point in the magnetic field where each pair of conductive loops is balanced. The antenna arrangement can further be used to determine the depth of the dipole field source using the magnitude of the field.

A pipe shuttle for moving a pipe segment from an operating position to a pipe box. The pipe shuttle has a pair of gripper arms flanking a cradle. The cradle has a spring-loaded pad that has a concave surface for holding a pipe segment. As the pipe shuttle moves from underneath a pipe box to near a cradle, rollers are positioned to engage a guide plate. When the shuttle is underneath the pipe box, the rollers engage the guide plate to keep the cradle open. When moved towards an operating position, the rollers no longer engage the guide plate and cause grippers to close on the pipe segment. The spring-loaded pad allows the pipe shuttle to be moved relative to the pipe segment when the pipe segment is in its operating position.
A brake system for maintaining an angular position of a spindle assembly. A pump-powered motor drives rotation of a spindle on the machine. When no rotation is desired, the spindle will slow, then stop at a desired angular orientation. A rotational sensor will determine the clock position, and a controller compares that to a desired angular orientation. If an error tolerance is exceeded, the motor will rotate the spindle back to the desired orientation.

A bearing assembly having independently rotatable concentric inner and outer tubes. A bearing chamber containing multiple bearings is disposed between the tubes, allowing thrust but not rotation to be transferred between them. The bearing chamber is sealed from the inside of the inner tube. To prevent high pressure fluid from leaking from the inner tube to an exterior of the tool through the bearing chamber, damaging components, a flow path is formed. An annular piston responds to high pressure within the bearing chamber and the inner tube, opening a flow path from the inner tube to the environment.
An offloading vacuum system. The system has a tank to capture debris from an excavation site. The debris is pulled into the tank due to a blower pulling air into an attached hose. An internal conveyor within the tank conveys material to an offloading hub. The offloading hub has a ground-facing door which opens to deposit debris into an external conveyor. The external conveyor, when deployed, can move debris from below the tank to a dump container with a wall greater than a height of the tank.

An insert for installation on an inner pipe member of a dual-pipe member assembly. The insert is interposed between an external shoulder formed on the inner pipe member and an internal shoulder formed in an outer pipe member. Shoulder-to-shoulder impacts between pipe members results in wear to the insert, rather than to either pipe member. The insert has the shape of an unclosed loop and is positioned within an endless external groove formed in the inner pipe member.

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.

A method for building a dual-member drill string comprising an inner drill string and an outer drill string. Inner pipe sections are connected using non-threaded connections, while outer pipe sections are connected using threaded connections. A new inner pipe section is rotated in a first direction until the inner pipe section applies torque to the existing inner pipe string. If the magnitude of the torque applied to the inner pipe string exceeds a pre-determined threshold value, the inner pipe section is automatically rotated in an opposite second direction. The inner pipe section rotates between opposite directions, once torque is sensed in each direction, until the inner pipe section is coupled to the inner pipe string.
A pipe assembly used in horizontal directional drilling operations. The pipe assembly has an outer member, an inner member, and first removable collar. The inner member has a polygonal outer profile of uniform shape along its length and is partially contained within the outer member. The first removable collar is supported on the inner member within the outer member and limits relative axial movement of the inner member and the outer member.
An engine cooling system comprising an exhaust enclosure formed in an engine compartment of a work machine. An exhaust processing system is situated within the exhaust enclosure. The exhaust enclosure is bounded in part by spaced upper and lower panels that are exposed to the ambient environment. At least one opening is formed in each panel. When an engine and fan also contained within the engine compartment are shut down, ambient air flows into the exhaust enclosure through the opening in the lower panel. The air flows around the exhaust processing system and back into the ambient environment through the opening formed in the upper panel.

A centrifugal fan is formed from an impeller installed within a casing. The impeller is formed from two plates that are interconnected by a plurality of blades. A duct extends through each blade. At each of its ends, the duct opens at one of the plates. Air enters the fan from through a central opening formed in one of the plates, moves to a medial zone between the plates, and exits the fan at the medial zone's unwalled periphery. Air also crosses the fan by way of the ducts formed within each blade.
