Description

Technical Field

[0001] The present invention relates to a method, system, storage medium and device for controlling deviation prevention of a rock drilling device, and belongs to the technical field of rock drilling device control. Background Art

[0002] A rock drilling jumbo is the core equipment for drilling blast holes in drill and blast method construction, and is widely used in fields such as mine exploitation, tunnel excavation, and water conservancy projects. The working environment of the rock drilling jumbo is harsh and the working conditions are complex and changeable. During the drilling process, the drill rod often deflects when encountering sudden changes in rock properties such as fissures, uneven hardness, interlayers, and karst caves. Therefore, during the drilling process, especially when drilling medium-deep holes, due to the increase in the slenderness ratio of the drill rod resulting in a decrease in stiffness, the deviation problem is more prominent. Drilling deviation seriously affects the subsequent blasting effect, leading to an increase in the large block rate of the blasted rock. Deviation of the surrounding drill holes will result in serious overbreak and underbreak phenomena, and additional support costs are required due to overbreak, and secondary treatment is required for underbreak. When the drill rod deflects severely, sticking and drill rod fracture accidents will also occur, which has a great impact on the service life of the drill bit, drill rod and rock drill.

[0003] During the operation of the rock drilling jumbo, the drill rod often deflects, and there is still no good solution for controlling the drill rod deflection. At present, there are mainly two types of control solutions for drill rod deflection in the industry. The overall deviation prevention effect is not ideal by improving the mechanical structure and adding a control system to achieve deviation prevention of the drill rod.

[0004] For achieving drill rod deviation prevention by improving the mechanical structure, the effect is not obvious, and new problems will also be brought.

[0005] For example, the utility model patent with the publication number CN213144395U discloses a deviation prevention drill rod, which realizes deviation prevention by arranging deviation prevention blocks on the circumference of the drill rod and improving the drill rod structure. This improvement seriously affects the slag discharge effect, increases the resistance of the drilling tool, causes serious wear, and affects the drilling efficiency.

[0006] For example, the utility model patent with the publication number CN214273514U discloses a mine deviation prevention drill bit, which realizes deviation prevention by installing a guiding and positioning body at the axis of the drill bit matrix and improving the drill bit structure. This improvement has a certain deviation prevention effect on the formation with uneven hardness, but for the sudden change formation such as fissures and karst caves, the guiding and positioning body installed at the axis of the drill bit end cannot play a good deviation prevention role, and the overall deviation prevention effect is poor.

[0007] For achieving drill rod deviation prevention by increasing relevant controls, the error of deviation judgment is large, the probability of misjudgment is very high, and some functions are difficult to apply in practice.

[0008] For example, the invention patent with the publication number CN106351900A discloses an anti-deviation rock drilling control system, which controls the hydraulic valve to act on the propulsion cylinder, hydraulic motor and impact mechanism by adding a deviation control system. In the face of complex drilling geology, especially in formations with rich fissures, the data collected during drilling is inaccurate. And when this data is compared and processed with empirical data, the empirical data cannot cover all complex geological conditions and rock drilling working conditions, which will cause the deviation control system to make wrong decisions and affect the anti-deviation effect and rock drilling efficiency.

[0009] For example, the utility model patent with the publication number CN203145832U discloses an anti-deviation control system for rock drilling tools. Stress sensors are evenly arranged in the drill pipe, and the processed sensor signals are compared and analyzed with the standard characteristic waveforms to judge whether the drill tool has a tendency to deviate. According to the judgment result, the control actuator is guided to make corresponding adjustments to the rock drilling parameters. Since the drill pipe is relatively thin, it is very difficult to install stress sensors in the drill pipe. Even if the installation is achieved, during the drilling process, the drill pipe is affected by impacts and the rock at the front end, and the vibration is relatively large, seriously affecting the accuracy of the data collected by the stress sensors.

[0058] Figure 1 is a flowchart of a method for controlling anti-deviation of a rock drilling device in Embodiment 1 of the present invention. Detailed Embodiments

[0059] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention.

[0060] Embodiment 1:

[0061] As Figure 1 shown, this embodiment provides a method for controlling the anti-deviation of a rock drilling device, including:

[0062] Obtain the three-dimensional coordinates of the hole opening, the inclination angle and the azimuth angle of the drill arm;

[0063] Compare the three-dimensional coordinates of the hole opening of the drill hole, the inclination angle and the azimuth angle of the drill arm obtained with the three-dimensional information of the designed hole position to obtain the deviation amount of the drill arm pose;

[0064] When the deviation amount of the drill arm pose exceeds the preset deviation value, output the adjustment parameters of the drill arm;

[0065] When the deviation amount of the drill arm pose does not exceed the preset deviation value, obtain the propulsion pressure of the hydraulic system of the rock drilling device during drilling and the rotational torque of the rock drilling device;

[0066] In response to the sudden change in the propulsion pressure of the hydraulic system of the rock drilling device and the rotational torque of the rock drilling device obtained, output the adjustment parameters of the hydraulic system of the rock drilling device according to the sudden change direction.

[0067] The specific steps include:

[0068] Step 1: Before the rock drilling device starts drilling, obtain the three-dimensional coordinates of the hole opening, the inclination angle and the azimuth angle of the drill arm.

[0069] The inclination angle of the drill arm represents the angle between the drill arm and the horizontal plane, and the azimuth angle of the drill arm represents the angle of horizontal rotation of the drill arm.

[0070] Step 2: Compare the three-dimensional coordinates of the hole opening of the drill hole, the inclination angle and the azimuth angle of the drill arm obtained with the three-dimensional information of the designed hole position to obtain the deviation amount of the drill arm pose.

[0071] The deviation amount of the drill arm pose includes: the spatial position deviation amount of the hole opening of the drill hole and the deviation amount of the drill hole axis direction.

[0072] Step 2.1: According to the three-dimensional coordinates of the hole opening of the drill hole obtained and the three-dimensional coordinates of the designed hole position , calculate the spatial position deviation amount of the hole opening of the drill hole :

[0073] .

[0074] Step 2.2: According to the inclination angle of the drill arm obtained and the azimuth angle , obtain the unit vector in the direction of the drilling axis :

[0075] ,

[0076] wherein, is the component of the unit vector in the direction of the drilling axis in the direction, is the component of the unit vector in the direction of the drilling axis in the direction, is the component of the unit vector in the direction of the drilling axis in the direction.

[0077] Step 2.3: According to the unit vector in the direction of the drilling axis and the direction vector of the drilling axis of the designed hole position, calculate the deviation amount of the drilling axis direction:

[0078] ,

[0079] wherein, is the component of the direction vector of the drilling axis of the designed hole position in the direction, is the component of the direction vector of the drilling axis of the designed hole position in the direction, is the component of the direction vector of the drilling axis of the designed hole position in the direction.

[0080] Step 3: Determine whether the deviation amount of the drill arm pose exceeds the preset deviation value.

[0081] If there is a deviation, enter Step 3.1 to adjust the pose of the opening drill arm. If there is no deviation, enter Step 4 to enter the drilling stage and monitor the drilling parameters.

[0082] Step 3.1: When the deviation amount of the drill arm pose exceeds the preset deviation value, output the adjustment parameters of the drill arm.

[0083] When the spatial position deviation amount of the drilling hole mouth > the preset position deviation value or the deviation amount of the drilling axis direction > the preset direction deviation value

[0084] Step 3.1.1: Based on the three-dimensional coordinates of the designed hole positions and the obtained three-dimensional coordinates of the drill hole orifices, obtain the adjustment parameters for the pitch displacement of the drill boom and the adjustment parameters for the yaw displacement of the drill boom.

[0085] Specifically, according to the value in the currently obtained three-dimensional coordinates of the drill hole orifices and the value in the three-dimensional coordinates of the designed hole positions, determine the adjustment parameters for the pitch displacement of the drill boom. According to the value in the currently obtained three-dimensional coordinates of the drill hole orifices and the value in the three-dimensional coordinates of the designed hole positions, determine the adjustment parameters for the yaw displacement of the drill boom.

[0086] Step 3.1.2: Based on the direction vector of the drill axis of the designed hole position and the unit vector of the drill axis direction, obtain the adjustment parameters for the rotary joints of the drill boom.

[0087] Specifically, according to the structures of different rock drilling devices, the adjustment parameters for the rotary joints of the drill boom are different.

[0088] Step 3.2: After the drill boom adjustment is completed, return to Step 1 and Step 2 until the deviation amount of the drill boom pose does not exceed the preset deviation value.

[0089] It should be noted that the preset deviation value can be flexibly adjusted according to different working conditions such as mine exploitation and tunnel tunneling to balance accuracy and construction efficiency.

[0090] In this embodiment, the deviation amount of the drill boom pose is calculated in real time, and the adjustment parameters of the drill boom are actively output, which can ensure the accuracy of the hole opening position.

[0091] This embodiment can avoid the risk of initial deviation caused by the positioning error of the drill boom. Especially during medium-depth drilling, it can greatly reduce the hole orifice positioning deviation and lay a foundation for subsequent drilling.

[0092] Step 4: When the deviation amount of the drill boom pose does not exceed the preset deviation value, obtain the propulsion pressure of the hydraulic system of the rock drilling device during drilling and the rotary torque of the rock drilling device.

[0093] Step 4.1: When the deviation amount of the drill boom pose does not exceed the preset deviation value, the drill boom pose is confirmed, and an instruction for the rock drilling device to enter the drilling stage is output, and the rock drilling device enters the drilling stage.

[0094] Step 4.2: In response to the instruction for the rock drilling device to enter the drilling stage, the hydraulic system of the rock drilling device operates and outputs the propulsion pressure and the rotary torque of the rock drilling device.

[0095] Step 4.3: Analyze the propulsion pressure of the hydraulic system of the rock drilling device and the rotary torque of the rock drilling device in real time.

[0096] Step 5: In response to the sudden changes in the propulsion pressure of the hydraulic system of the rock drilling device and the rotary torque of the rock drilling device, output the adjustment parameters of the hydraulic system of the rock drilling device according to the direction of the sudden change.

[0097] When sudden changes occur in the propulsion pressure of the hydraulic system of the obtained rock drilling device and the rotary torque of the rock drilling device, the drill pipe has a tendency to deflect.

[0098] Specifically, the borehole deviation includes two cases. Case 1: When entering hard rock from soft rock, both the propulsion pressure and the rotary torque suddenly increase, and the direction of the sudden change is that the increase amplitude exceeds the preset amplitude change threshold. Case 2: When entering soft rock (including working conditions such as fissures and karst caves) from hard rock, both the propulsion pressure and the rotary torque suddenly decrease, and the direction of the sudden change is that the decrease amplitude exceeds the preset amplitude change threshold.

[0099] If the direction of the sudden change is that the increase amplitude exceeds the preset amplitude change threshold, output the adjustment parameters of reducing the propulsion pressure, increasing the impact pressure, and increasing the rotary speed of the hydraulic system.

[0100] Specifically, output the adjustment parameters of reducing the propulsion pressure of the hydraulic system of the rock drilling device by 10%, increasing the impact pressure by 15%, and increasing the rotary speed by 20%.

[0101] If the direction of the sudden change is that the decrease amplitude exceeds the preset amplitude change threshold, output the adjustment parameters of increasing the propulsion pressure, reducing the impact pressure, and increasing the rotary speed of the hydraulic system.

[0102] Specifically, output the adjustment parameters of increasing the propulsion pressure of the hydraulic system of the rock drilling device by 15%, reducing the impact pressure by 10%, and increasing the rotary speed by 25%.

[0103] This embodiment can judge the deflection tendency caused by the formation change in real time and dynamically adjust the parameters of the hydraulic system. The present invention can effectively suppress the deflection of the drill pipe in complex formations such as fissures and karst caves.

[0104] This embodiment integrates the three-dimensional coordinates of the borehole orifice, the inclination angle and azimuth angle of the drill boom, the propulsion pressure and rotary torque of the hydraulic system, avoiding the monitoring defects of a single stress sensor or pressure signal in the prior art; this embodiment calibrates the pose of the opening drill boom first and then monitors the drilling parameters, which can improve the accuracy of deflection judgment, ensure the borehole quality, improve the subsequent blasting effect, reduce the incidence of faults such as drill pipe jamming and drill pipe fracture caused by drill pipe deflection, and extend the service life of the drill tool.

[0105] This embodiment realizes the full-process closed-loop control from the calibration of the opening drill boom pose to the adjustment of the drilling parameters, without manual experience intervention, solving the problems of lagging response and insufficient accuracy in traditional manual adjustment; the present invention can automatically adapt to complex formations with uneven hardness, interlayers, etc., significantly improving the degree of automation of the rock drilling operation, especially suitable for unmanned tunneling scenarios, and can greatly improve the drilling efficiency and construction quality.

[0106] In summary, through multi-source data fusion and phased closed-loop control, this embodiment realizes precise monitoring and dynamic correction of the entire drilling process.
