Description

Technical Field

[0001] This invention relates to the field of mining equipment technology, specifically to a new type of intelligent anchor drilling machine. Background Technology

[0002] Anchor bolt drilling rigs, as commonly used engineering machinery, are widely applied in civil engineering and rock consolidation. However, traditional anchor bolt drilling rigs have some limitations and shortcomings. First, the speed measuring devices of traditional rigs are unreliable and cannot accurately monitor the spindle speed, which poses difficulties for operation and performance evaluation. Second, existing rigs cannot monitor their operating status and performance parameters in real time, lacking timely understanding and adjustment of key indicators. Furthermore, traditional rigs are also inadequate in mechanical fault diagnosis, lacking vibration diagnostic capabilities and unable to accurately determine the occurrence and extent of mechanical faults. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide a new type of intelligent anchor drilling machine.

[0004] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: a novel intelligent anchor bolt drilling rig, comprising a drilling rig body, a motor transmission component above the drilling rig body and a pneumatic support leg below the drilling rig body, a drilling rig spindle on the output shaft of the motor transmission component, a water jacket on one end of the motor transmission component near the drilling rig spindle, a main controller embedded in the water jacket, a single-chip microcomputer processing chip and an induction coil, a temperature sensor and a triaxial vibration sensor electrically connected to the single-chip microcomputer processing chip, a detection hole corresponding to the position of the induction coil on the drilling rig spindle, and the induction coil calculating the rotational speed of the drilling rig spindle by detecting the passing pulse of the detection hole on the drilling rig spindle.

[0005] Furthermore, the pneumatic outrigger is equipped with a Hall sensor for detecting the number of times the pneumatic outrigger extends and a pressure sensor for detecting changes in air pressure inside the pneumatic outrigger cavity. The Hall sensor and the pressure sensor are electrically connected to a first wireless transceiver, and the microcontroller processing chip is electrically connected to a second wireless transceiver that wirelessly transmits data with the first wireless transceiver.

[0006] Furthermore, both the Hall sensor and the pressure sensor are powered by a first lithium battery built into the pneumatic outrigger.

[0007] Furthermore, the main controller is equipped with a second lithium battery, which is electrically connected to the microcontroller processing chip.

[0008] Furthermore, the triaxial vibration sensor uses an ADXL202E miniature accelerometer.

[0009] Furthermore, the main controller is equipped with an LCD screen, a photosensitive probe, an indicator light, and a manual button on its outer side, all electrically connected to the microcontroller processing chip.

[0010] Furthermore, the transparent portion of the liquid crystal display screen is made of high-strength PC transparent material.

[0011] The advantages of this invention compared to the prior art are:

[0012] 1. Reliable speed measuring device: Traditional speed measuring devices require the installation of Hall effect devices on the drill spindle, but this new drill uses an induction coil to calculate the rotational speed by detecting the pulses passing through the detection hole on the drill spindle, which greatly improves the reliability of the speed measuring device.

[0013] 2. Comprehensive Working Status Monitoring: The drilling rig is equipped with multiple sensors, including induction coils, temperature sensors, and triaxial vibration sensors. These sensors can monitor parameters such as the spindle speed, temperature, and vibration in real time, enabling accurate analysis and evaluation of the drilling rig's working status.

[0014] 3. Intelligent pneumatic outrigger control: Hall effect sensors and air pressure sensors are installed inside the pneumatic outriggers of the drilling rig, and are connected to a microcontroller chip via a wireless transceiver. This allows for real-time detection of the number of outrigger extensions and changes in air pressure within the chamber, thereby accumulating the number of working operations and duration to accurately determine the number of anchor bolts driven into the rig each day.

[0015] 4. Multifunctional Main Controller: The main controller is equipped with a microcontroller chip and a second lithium battery, as well as an LCD screen, photosensitive probe, indicator lights, and manual buttons. Through the main controller, operators can monitor the lifespan parameters of the pneumatic outriggers, the drilling rig's speed and torque, and other operating parameters in real time, and make settings and adjustments as needed.

[0016] 5. Powerful vibration diagnostic function: By installing the ADXL202E miniature accelerometer, the drilling rig can perform vibration diagnostics. For potential faults in the pneumatic motor, by analyzing the vibration acceleration signal and rotational speed parameters, the rig's own state parameters and the rock hardness parameters of the coal seam can be obtained, thereby enabling the judgment and prediction of mechanical faults.

[0017] Overall, this new intelligent anchor drilling rig combines advanced sensor technology and an intelligent control system to achieve real-time monitoring and analysis of the drilling rig's working status and performance, thereby improving the rig's reliability, safety, and efficiency.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0025] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0026] To make the content of this invention easier to understand, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] Combined with appendix Figure 1 -Appendix Figure 4A novel intelligent anchor drilling rig includes a drilling rig body 1, a motor transmission component 2 on top of the drilling rig body 1, and pneumatic outriggers 3 below the drilling rig body 1. The output shaft of the motor transmission component 2 is equipped with a drilling spindle 4. A water jacket 5 is located at one end of the motor transmission component 2 near the drilling spindle 4. A main controller 6 is embedded in the water jacket 5. The main controller 6 contains a microcontroller chip 7 and an induction coil 8, a temperature sensor 9, and a triaxial vibration sensor 10 electrically connected to the microcontroller chip 7. The drilling spindle 4 has detection holes 11 corresponding to the positions of the induction coil 8. The induction coil 8 calculates the rotational speed of the drilling spindle 4 by detecting the pulses passing through the detection holes 11 on the drilling spindle 4 and calculating the pulse interval time to complete the rotational speed conversion.

[0028] P = 1 / t * 60 (rpm)

[0029] Where the rotational speed is P; the interval time is t; because the drilling rig spindle 4 will generate large vibrations when it is working, this detection method does not require the installation of Hall effect devices on the drilling rig spindle 4, which greatly improves the reliability of the speed measuring device.

[0030] In one embodiment, the pneumatic outrigger 3 is provided with a Hall sensor 12 for detecting the number of times the pneumatic outrigger 3 extends and a pressure sensor 13 for detecting changes in air pressure inside the pneumatic outrigger 3. The Hall sensor 12 and the pressure sensor 13 are electrically connected to a first wireless transceiver 14, and the microcontroller processing chip 7 is electrically connected to a second wireless transceiver 15 that wirelessly transmits data with the first wireless transceiver 14.

[0031] In one embodiment, both the Hall sensor 12 and the air pressure sensor 13 are powered by a first lithium battery 16 built into the pneumatic outrigger 3. The number of times the Hall sensor 12 in the pneumatic outrigger 3 switches on and off serves as the reference base N1 for the anchor rods. Once the N1 base is set, the system automatically accumulates the rotational speed P and the following Fz over time. If this is completed within 2 to 5 minutes and the accumulated value is within the normal range, the N1 base is considered valid, and the anchor rod count is incremented by 1. If the working time is too short, or the accumulated data deviation is greater than the normal range, the N1 base is considered invalid, and the anchor rod count is not incremented. The number of times the pneumatic outrigger 3 falls back can accurately determine how many anchor rods the drilling rig drives in each day. When the pneumatic outrigger 3 is deployed, the pressure sensor 13 embedded in the pneumatic circuit system of the pneumatic outrigger 3 sends a working status signal to the microcontroller processing chip 7. The preset program in the microcontroller processing chip 7 determines whether the system is in working condition based on the value of the signal, thereby accumulating the number of working operations and the working time.

[0032] In one embodiment, the main controller 6 is equipped with a second lithium battery 17, which is electrically connected to the microcontroller processing chip 7.

[0033] In one embodiment, the triaxial vibration sensor 10 uses an ADXL202E miniature accelerometer. This device applies vibration diagnostic technology to engineering machinery such as anchor drilling rigs. Given the susceptibility of pneumatic motors to failure, a triaxial vibration sensor 10 is installed to detect their vibration acceleration signals. The system uses the ADXL202E miniature accelerometer. The ADXL202E is a complete, integrated dual-axis acceleration measurement system on a separate IC circuit, including a multi-chip silicon surface micromechanical sensor and a separate modulation circuit for open-loop acceleration measurement. The direction output circuit for each axis converts the analog signal into a duty cycle timing signal for processing by the microprocessor's timer / counter. The ADXL202E can measure accelerations up to 2g, can measure static accelerations such as gravity, and can also be used as a tilt sensor. The motor drive component 2 is the power source for the entire drilling system. If the motor drive component 2 fails, it will have a serious impact on the entire drilling system. When the motor drive component 2 fails, abnormal vibrations will occur, typically accompanied by significant noise. However, if noise detection makes fault analysis difficult, but a small quantitative change leads to a qualitative change, then the vibration curve becomes crucial. By analyzing the vibration frequency and amplitude using a pre-programmed microcontroller chip 7, combined with rotational speed parameters, the drilling rig's own state parameters can be derived. Simultaneously, vibration analysis along the four axes of the drilling rig's main shaft can yield vibration parameters for the coal seam, thus determining the rock hardness parameters. The values ​​for each shaft pair are Fx, Fy, and Fz. Fz represents the magnitude of the main shaft's axial vibration; a larger value indicates greater rock hardness at the front end. Fx and Fy, as vibration parameters of the machine body, are used for diagnosing mechanical faults.

[0034] In one embodiment, the main controller 6 is equipped with an external LCD screen 18, a photosensitive probe 19, an indicator light 20, and a manual button 21, all electrically connected to the microcontroller processing chip 7. The LCD screen 18 can display the lifespan parameters of the pneumatic outrigger 3, the actual rotational speed and torque of the drilling rig. When the ambient light intensity changes significantly, the display system is activated and immediately displays the relevant operating parameters. Besides the photosensitive probe, the manual button 21 can also trigger the system to display the operating parameters. The initial value of the pneumatic outrigger 3 lifespan parameter N2 is set to 8000. Each time the pneumatic outrigger 3 extends, the lifespan parameter is decremented by 1. Furthermore, according to… The working pressure parameter (P2) of the pneumatic outrigger 3 is accumulated over time during operation. If the accumulated pressure (P2) exceeds the average value, the lifespan parameter is reduced by 1. When the lifespan parameter of the pneumatic outrigger 3 is less than 100, the equipment will issue a warning that the outrigger's lifespan has expired. When the drilling rig's lifespan reaches the critical data, in addition to the screen prompting the operator in the wake-up state, the yellow indicator light 20 set at the bottom of the screen will flash continuously, indicating that the equipment needs maintenance. Torque is related to the rotational speed; the higher the rotational speed, the lower the torque. In addition, the greater the vibration, the greater the output torque. It is also related to the air leg pressure; the greater the pressure, the greater the output torque. From this, the following empirical formula is derived:

[0035] M=1 / P*20+Fx*0.2+Fy*0.2+P2*0.4

[0036] Where M is the output torque.

[0037] In one embodiment, the transparent portion of the liquid crystal display 18 is made of a high-strength PC transparent material.

[0038] In the specific implementation of this invention, first ensure that the drill body 1 and the motor transmission component 2 are properly connected, with the pneumatic outriggers 3 located below the drill body 1. Confirm that the water jacket 5 is equipped with the main controller 6, and ensure that the microcontroller chip 7 and each sensor (induction coil 8, temperature sensor 9, and triaxial vibration sensor 10) within the main controller 6 are electrically connected correctly. Then, turn on the LCD screen 18 on the main controller 6 and set relevant parameters as needed, such as the actual rotational speed and torque of the drill. This can be done via the manual button 21 or the photosensitive probe 19 on the LCD screen 18. Next, place the drill body 1 at the location where drilling is required, ensuring that the pneumatic outriggers 3 are firmly supported. Turn on the power to the motor transmission component 2, driving the drill spindle 4 to begin rotating. Simultaneously, the pneumatic outriggers 3 extend to maintain the stability of the drill. During the drilling process, the microcontroller chip 7 within the main controller 6 detects the rotational speed of the drill spindle 4 through the induction coil 8 and calculates the rotational speed and pulse interval time. The induction coil 8, temperature sensor 9, and triaxial vibration sensor 10 collect data in real time, including the number of extensions of the pneumatic outriggers 3, air pressure changes, and the vibration acceleration of the drilling rig. The microcontroller chip 7 performs status checks and fault diagnosis based on the collected data. For example, it determines the number of anchor bolts based on the number of extensions of the pneumatic outriggers 3 and records the number of operations and working time. Vibration acceleration analysis can determine the working status and mechanical faults of the drilling rig. When drilling is complete or the drilling needs to be stopped, the power to the motor transmission component 2 is turned off, stopping the rotation of the drilling rig spindle 4. The pneumatic outriggers 3 retract and return to their original position, moving the drilling rig body 1 away from the working position.

[0039] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
