[0002] In the process of calculating the kinematics of the drilling rig's boom position, the correspondence and accuracy between the measured values of the drilling rig's sensor system and the actual position of the equipment are fundamental to the entire calculation.

[0007] According to some embodiments of this application, the step of adjusting the drill arm based on the measured values fed back by the left and right angle sensors of the front amplitude transformer and the pitch rotation angle of the drill arm, so that the drill arm is in a centered state and a horizontal state respectively, and performing zero-position calibration of the left and right angle sensors and the up and down angle sensors of the front amplitude transformer when the drill arm is in the centered state and the horizontal state respectively, includes: Based on the measurement value fed back by the front amplitude left and right angle sensor, the drill arm is adjusted to rotate left and right so that the drill arm is in the center position.

See below. Figures 1 to 5 The embodiments of this application will be further described below.
[0023] like Figure 1 and Figure 2 As shown in the embodiment of this application, a drilling rig calibration system is proposed and applied to a drilling rig. The drilling rig includes a vehicle body with outriggers, a boom mounted on the vehicle body, a drill arm connected to the boom, a feed beam connected to the drill arm, a drill bit located on the feed beam, and a variable amplitude left and right angle sensor, a variable amplitude up and down angle sensor, a front variable amplitude left and right angle sensor, a front variable amplitude up and down angle sensor, a straightening angle sensor, and a torsion angle sensor. The variable amplitude left and right angle sensor is used to measure the left and right rotation angle of the boom, the variable amplitude up and down angle sensor is used to measure the pitch rotation angle of the boom, the front variable amplitude left and right angle sensor is used to measure the left and right rotation angle of the drill arm, the front variable amplitude up and down angle sensor is used to measure the pitch rotation angle of the drill arm, the straightening angle sensor is used to measure the pitch rotation angle of the feed beam, and the torsion angle sensor is used to measure the left and right roll angle of the feed beam. The drilling rig calibration system includes a controller and components electrically connected to the controller: Vehicle tilt sensor is used to measure the vehicle's pitch and roll angles. The boom left displacement sensor is used to measure the length of the boom left cylinder; The boom right displacement sensor is used to measure the length of the boom right cylinder. Boom tilt sensor, used to measure the boom pitch and rotation angle; Boom extension displacement sensor, used to measure boom extension displacement; Drill arm tilt sensor, used to measure the pitch and rotation angle of the drill arm; The propulsion beam tilt sensor is used to measure the roll rotation angle and pitch rotation angle of the propulsion beam. Compensating for the expansion and contraction displacement sensor, used to measure the expansion and contraction displacement of the propulsion beam; A thrust displacement sensor is used to measure the extension and retraction displacement of the drill bit.
[0024] In this embodiment of the application, by establishing a new sensing system for the drilling rig, an automatic calibration process can be designed based on the new sensing system to complete the calibration of the original sensing system on the drilling rig. No manual intervention is required during the calibration process, which can significantly shorten the calibration time of the drilling rig sensing system and improve the measurement accuracy of the drilling rig sensing system and the boom positioning accuracy.
[0025] Existing drilling rigs typically include a chassis with outriggers, a boom mounted on the chassis, a drill arm connected to the boom, a feed beam connected to the drill arm, a drill bit located on the feed beam, and a sensing system. The sensing system includes a luffing left and right angle sensor, a luffing up and down angle sensor, a front luffing left and right angle sensor, a front luffing up and down angle sensor, a straightening angle sensor, a torsion angle sensor, a compensation displacement sensor, and a feed displacement sensor. These sensors need to be calibrated before the drilling rig is put into operation.
[0026] The boom is connected to the vehicle body via a lower triangle, which is the boom slewing mechanism. Located between the drilling rig's vehicle body and the boom, this lower triangle is a base that can rotate left and right and pitch up and down. It controls the boom's left and right slewing and pitching movements. Left and right slewing refers to driving the entire boom, along with its entire upper structure at the front end (including the upper triangle, drill arm, etc.), to rotate left or right on the horizontal plane. The variable amplitude left and right angle sensor in the sensing system is used to measure the boom's left and right rotation angle. Pitching refers to driving the boom to lift and lower, i.e., rotate up and down. The variable amplitude up and down angle sensor in the sensing system is used to measure the boom's up and down rotation angle.
[0027] The drill arm is connected to the boom via an upper triangle, which is the drill arm rotation mechanism. Located between the end of the boom and the drill arm, the upper triangle allows for more precise adjustments based on the general orientation determined by the lower triangle. It controls the left-right swing and up-down pitch of the drill arm, similar to the control of the boom's left-right rotation and up-down pitch, so it will not be described in detail here. Similarly, the sensing system includes a front amplitude left-right angle sensor and a front amplitude up-down angle sensor, which are used to detect the corresponding left-right and up-down rotation angles of the drill arm.
[0028] The propulsion beam is connected to the drill arm via a rotary cylinder. The rotary cylinder can drive the propulsion beam to rotate 360° around its axis, thus enabling the propulsion beam to roll left and right. The torsion angle sensor in the sensing system is used to measure the left and right roll angle of the propulsion beam. A telescopic cylinder is also installed at the connection between the propulsion beam and the drill arm, which enables the propulsion beam to pitch up and down. The straightening angle sensor in the sensing system is used to measure the pitch rotation angle of the propulsion beam.
[0029] Specifically, such as Figure 1 and Figure 2 As shown, it is understandable that Figure 1 and Figure 2The diagram only includes the boom, drill arm, push beam, and drill bit; it does not include the vehicle body. Furthermore, the sensors are not shown; only their potential locations are indicated. The luffing left / right angle sensor can be located at point a in the diagram to measure the boom's left / right rotation angle; the luffing up / down angle sensor can be located at point b to measure the boom's pitch rotation angle; the front luffing left / right angle sensor can be located at point c to measure the drill arm's left / right rotation angle; the front luffing up / down angle sensor can be located at point d to measure the drill arm's pitch rotation angle; the straightening angle sensor can be located at point e to measure the push beam's pitch rotation angle; and the torsion angle sensor can be located at point f to measure the push beam's left / right roll angle.
[0030] To calibrate the aforementioned sensing systems, including the luffing left and right angle sensors, luffing up and down angle sensors, front luffing left and right angle sensors, front luffing up and down angle sensors, centering angle sensors, and torsion angle sensors, this application proposes a drilling rig calibration system. This system includes a new sensing system and a controller. The new sensing system includes a body tilt sensor, a boom left displacement sensor, a boom right displacement sensor, a boom tilt sensor, a boom telescopic displacement sensor, a drill arm tilt sensor, a feed beam tilt sensor, a compensation telescopic displacement sensor, and a feed displacement sensor. In some cases, the drilling rig equipment includes both the existing sensing system and the various sensors included in the new sensing system; all sensors together constitute the new sensor system.
[0031] Specifically, such as Figure 1 and Figure 2As shown, the body tilt sensor can be installed at point g in the diagram, or on the body (not shown), to measure the body's pitch and roll angles. The boom left displacement sensor can be installed inside the boom left cylinder, specifically at point h in the diagram, to measure the boom left cylinder length. The boom right displacement sensor can be installed inside the boom right cylinder, specifically at point i in the diagram, to measure the boom right cylinder length. The boom tilt sensor can be installed on the boom, specifically at point j in the diagram, to measure the boom pitch angle. The boom telescopic displacement sensor can be installed inside the boom telescopic cylinder. Specifically, a sensor can be installed at point k in the diagram to measure the extension and retraction displacement of the boom; a drill arm tilt sensor can be installed on the drill arm, specifically at point l in the diagram, to measure the drill arm pitch and rotation angle; a feed beam tilt sensor can be installed on the feed beam, specifically at point m in the diagram, to measure the feed beam roll and pitch rotation angles; a compensation extension and retraction displacement sensor can be installed inside the feed beam compensation cylinder, specifically at point n in the diagram, to measure the feed beam extension and retraction displacement; and a feed displacement sensor can be installed at the drill bit end, specifically at point o in the diagram, to measure the drill bit extension and retraction displacement.
[0032] Among them, the body tilt sensor can assist in leveling the front of the vehicle; the boom left displacement sensor, boom right displacement sensor, and boom tilt sensor can assist in lower triangular calibration, that is, calibrating the luffing left and right angle sensors and the luffing up and down angle sensors; the drill arm tilt sensor and the front luffing left and right angle sensor can assist in upper triangular calibration, that is, calibrating the front luffing up and down angle sensors and the front luffing left and right angle sensors themselves; the push beam tilt sensor can detect the angle of the push beam in the up and down pitch direction and the left and right roll direction, that is, measure the pitch rotation angle and the roll rotation angle of the push beam, so it can assist in the calibration of the straightening angle sensor and the torsion angle sensor; the boom telescopic displacement sensor, the compensation telescopic displacement sensor, and the push displacement sensor can achieve their own calibration.
[0033] like Figure 3 As shown in the embodiments of this application, a drilling rig calibration method is also proposed. This method can be applied to the above-mentioned drilling rig calibration system. The drilling rig calibration method includes the following steps: Step 101: Based on the vehicle body pitch and roll angles, adjust the outriggers to make the vehicle body level. Step 102: Based on the length of the left cylinder of the boom, the length of the right cylinder of the boom, the boom pitch rotation angle, and the boom telescopic displacement, adjust the boom so that the boom is in the center position, the horizontal position, and the fully retracted position respectively. Under the conditions of the boom being in the center position, the horizontal position, and the fully retracted position respectively, perform zero-position calibration on the luffing left and right angle sensor, the luffing up and down angle sensor, and the boom telescopic displacement sensor. Step 103: Based on the measured values fed back by the left and right angle sensors of the front amplitude transformer and the pitch and rotation angle of the drill arm, adjust the drill arm so that the drill arm is in the center state and the drill arm is in the horizontal state respectively. Under the condition that the drill arm is in the center state and the drill arm is in the horizontal state respectively, perform zero-position calibration on the left and right angle sensors of the front amplitude transformer and the up and down angle sensors of the front amplitude transformer. Step 104: Based on the roll rotation angle, pitch rotation angle, and telescopic displacement of the propulsion beam, adjust the propulsion beam so that it is in the upright posture state, the horizontal posture state, and the fully retracted posture state, respectively. Under the conditions of the propulsion beam being in the upright posture state, the horizontal posture state, and the fully retracted posture state, perform zero-position calibration on the torsion angle sensor, the straightening angle sensor, and the compensation telescopic displacement sensor. Step 105: Based on the drill bit extension and retraction displacement, adjust the drill bit so that it is in the fully retracted state, and perform zero-position calibration on the feed displacement sensor when the drill bit is in the fully retracted state.
[0034] In this embodiment, by establishing a new sensing system for the drilling rig, an automated calibration process can be designed based on this new sensing system to calibrate the original sensing system on the drilling rig. No manual intervention is required during the calibration process, significantly reducing the calibration time of the drilling rig's sensing system and improving the measurement accuracy of the drilling rig's sensing system and the boom positioning accuracy. The calibration process sequentially involves automatic leveling of the vehicle body, adjustment of the boom, adjustment of the drill arm, adjustment of the feed beam, and adjustment of the drill bit to complete the calibration of each sensor on the drilling rig, while simultaneously adjusting the drilling rig to its reference position before formal operation.
[0035] In some implementations, the outriggers are adjusted based on the vehicle's pitch and roll angles to bring the vehicle to a horizontal position.
[0036] In this embodiment, by acquiring the vehicle body pitch and roll angles measured by the vehicle body tilt sensor, the extension and retraction of the front, rear, left, and right outriggers are adjusted so that the vehicle body pitch and roll angles fed back by the vehicle body tilt sensor are both less than a first threshold. At this point, it can be determined that the vehicle body has reached a level state, and the next step can be carried out. The first threshold can be 0.1°.
[0037] In some implementations, based on the length of the left boom cylinder, the length of the right boom cylinder, the boom pitch angle, and the boom telescopic displacement, the boom is adjusted to be in a centered state, a horizontal state, and a fully retracted state, respectively. Then, under these conditions, the luffing angle sensors (left and right), luffing angle sensors (up and down), and boom telescopic displacement sensors are zero-point calibrated, including: Based on the lengths of the left and right hydraulic cylinders of the boom, adjust the boom to rotate left and right so that the boom is in the center position. When the boom is in the center position, perform zero-position calibration on the left and right angle sensors of the luffing. Based on the boom pitch and rotation angle, adjust the boom up and down rotation to make the boom horizontal, and when the boom is horizontal, perform zero-position calibration on the luffing up and down angle sensor. Based on the boom extension and retraction displacement, the boom retraction is adjusted so that the boom is in the fully retracted state, and the boom extension and retraction displacement sensor is calibrated to zero position when the boom is in the fully retracted state.
[0038] In this embodiment, firstly, by acquiring the length of the left cylinder of the boom measured by the left boom displacement sensor and the length of the right cylinder of the boom measured by the right boom displacement sensor, the extension and retraction of the left and right cylinders are adjusted to drive the boom to rotate left and right, so that the lengths of the left and right cylinders are equal. This determines that the boom is in the centered state, and the luffing angle sensor is zero-calibrated at this time. Secondly, by acquiring the boom pitch angle measured by the boom tilt angle sensor, the extension and retraction of the left and right cylinders are adjusted to drive the boom to rotate up and down, so that the boom pitch angle is less than a first threshold. This determines that the boom is in the horizontal state, and the luffing angle sensor is zero-calibrated at this time. The first threshold can be 0.1°. Finally, by measuring the boom extension and retraction displacement by the boom extension and retraction displacement sensor, the boom is adjusted to retract to the limit position, i.e., retracted until the boom extension and retraction displacement remains unchanged. This determines that the boom is in the fully retracted state, and the boom extension and retraction displacement sensor is zero-calibrated at this time.
[0039] In some implementations, based on the lengths of the left and right hydraulic cylinders of the boom, the boom is adjusted to rotate left and right to bring it into a centered position. While the boom is in this centered position, the luffing angle sensors are zero-point calibrated, including: Adjust the boom to rotate to the left limit position and obtain the limit boom left cylinder length value measured by the boom left displacement sensor; Adjust the boom to rotate to the right limit position and obtain the limit boom right cylinder length value measured by the boom right displacement sensor; Calculate the median value of the maximum boom left cylinder length and the maximum boom right cylinder length to obtain the median cylinder length; Determine the range of values for the length of the center cylinder based on the median length of the cylinder. Adjust the boom to rotate left and right so that the measured lengths of the left and right cylinders of the boom are both within the range of the length of the center cylinder. When the lengths of the left and right cylinders of the boom are both within the range of the length of the center cylinder, the boom is in the center position.
[0040] Specifically, for example, if the maximum left cylinder length of the boom is 3 and the maximum right cylinder length is 5, then the cylinder length is 4. In this case, the boom rotation needs to be adjusted so that the lengths of both the left and right cylinders approach 4 in order to center the boom back to its normal position. It is understood that the above process is only for illustrative purposes and no specific units are mentioned.
[0041] Specifically, based on the median length of the hydraulic cylinder, the range of the centered hydraulic cylinder length can be determined by adding or subtracting 1mm from the median length of the hydraulic cylinder.
[0042] In some implementations, based on the measured values fed back by the left and right angle sensors of the front amplitude transformer and the pitch rotation angle of the drill arm, the drill arm is adjusted so that the drill arm is in a centered state and a horizontal state, respectively. Then, while the drill arm is in the centered state and the horizontal state, the left and right angle sensors of the front amplitude transformer and the up and down angle sensors of the front amplitude transformer are zero-position calibrated, including: Based on the measurement values fed back by the left and right angle sensors of the front amplitude transformer, the drill arm is adjusted to rotate left and right so that the drill arm is in the center position. When the drill arm is in the center position, the left and right angle sensors of the front amplitude transformer are calibrated to zero position. Based on the pitch rotation angle of the drill arm, adjust the up and down rotation of the drill arm to make the drill arm horizontal, and perform zero-position calibration on the front amplitude up and down angle sensor when the drill arm is in a horizontal state.
[0043] In this embodiment, the left and right angle sensors of the front amplitude transformer are first calibrated to zero position, followed by the up and down angle sensors of the front amplitude transformer. Zero-position calibration of the up and down angle sensors is performed by acquiring the drill arm pitch rotation angle measured by the drill arm tilt angle sensor, adjusting the drill arm's up and down rotation so that the drill arm pitch rotation angle is less than a first threshold. This indicates that the drill arm is in a horizontal state, at which point the up and down angle sensors of the front amplitude transformer are calibrated to zero position. The first threshold can be 0.1°.
[0044] In some implementations, the drill arm is rotated left and right based on the measurement values fed back by the left and right angle sensors of the front amplitude transformer, so that the drill arm is in a centered state, including: Adjust the drill arm to rotate to the left limit position and obtain the first angle value fed back by the left and right angle sensors of the front amplitude transformer. Adjust the drill arm to rotate to the right limit position and obtain the second angle value fed back by the left and right angle sensors of the front amplitude transformer; Calculate the median of the first and second angle values to obtain the third angle value; Determine the range of centering angle values based on the third angle value; Adjust the drill arm to rotate left and right so that the measured value fed back by the left and right angle sensors of the front amplitude transformer is within the center angle range. When the measured value fed back by the left and right angle sensors of the front amplitude transformer is within the center angle range, the drill arm is in the center state.
[0045] Specifically, based on the third angle value, the range of centering angle values can be determined by adding or subtracting 0.1° from the third angle value.
[0046] In some implementations, the propulsion beam is adjusted based on its roll rotation angle, pitch rotation angle, and telescopic displacement to achieve three states: a positive posture, a horizontal posture, and a fully retracted posture. Then, under these conditions, the torsion angle sensor, the straightening angle sensor, and the compensation telescopic displacement sensor are calibrated to zero position. Based on the tumbling rotation angle of the propulsion beam, the left and right tumbling of the propulsion beam is adjusted so that the tumbling rotation angle of the propulsion beam is less than the first threshold. When the tumbling rotation angle of the propulsion beam is less than the first threshold, the propulsion beam is in the correct posture state, and the torsion angle sensor is calibrated at zero position. Based on the pitch rotation angle of the propulsion beam, adjust the up and down rotation of the propulsion beam to make the propulsion beam horizontal, and perform zero-position calibration on the straightening angle sensor when the propulsion beam is horizontal. Based on the telescopic displacement of the propulsion beam, the telescopic displacement is adjusted to retract so that the propulsion beam is in a fully retracted state. Then, the compensating telescopic displacement sensor is calibrated to zero position while the propulsion beam is in a fully retracted state.
[0047] In this embodiment, firstly, by acquiring the roll rotation angle of the propulsion beam measured by the propulsion beam tilt angle sensor, the propulsion beam is adjusted to roll left and right until the roll rotation angle is less than a first threshold, thus determining that the propulsion beam is in a positive posture state. At this time, the torsion angle sensor is zero-calibrated. Secondly, by acquiring the pitch rotation angle of the propulsion beam measured by the propulsion beam tilt angle sensor, the propulsion beam is adjusted to rotate up and down until the pitch rotation angle is less than a first threshold, thus determining that the propulsion beam is in a horizontal state. At this time, the straightening angle sensor is zero-calibrated. The first threshold can be 0.1°. Finally, by measuring the extension displacement of the propulsion beam measured by the compensation extension displacement sensor, the propulsion beam is adjusted to retract to its limit position, i.e., retracted until the extension displacement remains unchanged, thus determining that the propulsion beam is in a fully retracted state. At this time, the compensation extension displacement sensor is zero-calibrated.
[0048] In some implementations, the drill bit is adjusted based on its extension and retraction displacement to ensure it is in a fully retracted state. Then, the feed displacement sensor is calibrated to zero position when the drill bit is in this fully retracted state. This can be achieved by acquiring the drill bit extension and retraction displacement measured by the feed displacement sensor, adjusting the drill bit to its limit position (i.e., retracting until the extension and retraction displacement remains constant), thus determining that the drill bit is in a fully retracted state. At this point, the feed displacement sensor is calibrated to zero position.
[0049] In some implementations, after completing the calibration of all sensors in the sensing system according to the above-described automatic calibration process, the relevant calibration values are immediately written into the controller's power-off retention register, ensuring that the data is not lost after the system is powered off. It is understood that when the device replaces sensors or its structure changes, the self-calibration system needs to be restarted to perform the sensor system calibration again.
[0050] In some implementations, the drilling rig is equipped with luffing left and right angle sensors, luffing up and down angle sensors, front luffing left and right angle sensors, front luffing up and down angle sensors, straightening angle sensors, and torsion angle sensors, as well as vehicle body tilt sensors, boom left displacement sensors, boom right displacement sensors, boom tilt angle sensors, boom telescopic displacement sensors, drill arm tilt angle sensors, feed beam tilt angle sensors, compensation telescopic displacement sensors, and feed displacement sensors, which together constitute the drilling sensing system. The system consists of 15 sensors, which not only enables the self-calibration system function but also makes the equipment measurement system redundant, thereby improving the reliability of the system.
