Furthermore, existing propulsion systems have a slow response speed to environmental changes, which may lead to a decrease in drilling accuracy and affect the overall operational results. Summary of the Invention

[0011] In an exemplary embodiment of the present invention, the intelligent propulsion system for coal mine drilling rigs further includes: a remote interaction module; the remote interaction module is connected to the main control unit.

[0012] The technical principle of the intelligent propulsion system for coal mine drilling rigs based on adaptive control technology provided in this invention is as follows: The main control unit receives the working status information of the drilling rig host and combines it with real-time data fed back by the environmental perception module to dynamically adjust the action mode of the power switching module, thereby achieving precise control of the first and second drive components.

Detailed Implementation

[0025] This invention provides an intelligent propulsion system for coal mine drilling rigs based on adaptive control technology, the structure of which is as follows: Figure 1 As shown, the system includes a main control unit 1, a power switching module 2, a first drive assembly 3, a second drive assembly 4, and a feedback acquisition module 5. The input of the main control unit 1 is connected to the drilling rig host, and its output is connected to the power switching module 2. The main control unit 1 controls the power switching module 2 by receiving the operating status information of the drilling rig host. The input of the power switching module 2 is connected to the drilling rig host, and its output is connected to both the first drive assembly 3 and the second drive assembly 4, respectively, for distributing hydraulic power to the two drive assemblies. The feedback acquisition module 5 is located between the first drive assembly 3 and the second drive assembly 4, for collecting real-time operating status data of the two drive assemblies and transmitting it to the main control unit 1.

[0026] The first drive assembly 3 includes a first hydraulic actuator 7 and a first pressure regulator, and the second drive assembly 4 includes a second hydraulic actuator 8 and a second pressure regulator. The input ends of the first hydraulic actuator 7 and the first pressure regulator are connected to the power switching module 2, and the input ends of the second hydraulic actuator 8 and the second pressure regulator are also connected to the power switching module 2. The specific structure of the power switching module 2 is as follows: Figure 2 As shown, a three-way valve 6 is used as the core component. The inlet end of the three-way valve 6 is connected to the drilling rig host, the first outlet end is connected to the first drive assembly 3, and the second outlet end is connected to the second drive assembly 4. The three-way valve 6 adjusts the flow direction of hydraulic oil according to the instructions of the main control unit 1, thereby realizing the switching of hydraulic power between the first drive assembly 3 and the second drive assembly 4.

[0027] The environmental perception module 9 and the auxiliary control module 10 work together, and their cooperative relationship is as follows: Figure 3As shown. The environmental sensing module 9 includes a rock stress sensor 11 and a temperature sensor 12, both of which are connected to the control terminal of the auxiliary control module 10. The rock stress sensor 11 is installed near the drill bit to monitor changes in rock stress in the drilling area, and the temperature sensor 12 is installed in the hydraulic system's oil circuit to monitor changes in hydraulic oil temperature. The input terminals of the auxiliary control module 10 are connected to the first drive assembly 3 and the second drive assembly 4, respectively, and the output terminal is connected to the display terminal. The auxiliary control module 10 adjusts the operating parameters of the first drive assembly 3 and the second drive assembly 4, such as hydraulic pressure and propulsion speed, based on the data fed back by the environmental sensing module 9.

[0028] The safety protection module and the near-field communication module together constitute the system's safety assurance mechanism. The control terminal of the safety protection module is connected to the environmental sensing module 9, its input terminals are connected to the first drive component 3 and the second drive component 4 respectively, and its output terminal is connected to the near-field communication module. When the rock stress sensor 11 detects that the rock stress exceeds a preset threshold, the safety protection module analyzes whether there are potential risks in the current working condition and sends a warning signal to the operator through the near-field communication module. At the same time, the safety protection module automatically adjusts the operating status of the first drive component 3 and the second drive component 4, reducing the propulsion force to prevent equipment damage or accidents.

[0029] The alarm module is directly connected to the main control unit 1. When the system detects an abnormal condition, such as hydraulic pressure imbalance or jamming of the three-way valve 6, the alarm module will alert the operator through audible and visual signals to address the problem promptly. The remote interaction module is also connected to the main control unit 1, allowing the operator to interact with the main control unit 1 via a wireless network. The operator can use the remote interaction module to view the drilling rig's operating status in real time, such as parameters like hydraulic pressure, feed speed, and rock stress, and remotely adjust operating parameters, thereby further enhancing the system's flexibility and intelligence.

[0030] In practical applications, the main control unit 1 dynamically adjusts the operating mode of the three-way valve 6 by receiving the working status information of the drilling rig host and the real-time data fed back by the environmental perception module 9, so as to achieve precise control of the first drive component 3 and the second drive component 4. For example, when the drilling rig host is in high-speed propulsion mode, the main control unit 1 controls the three-way valve 6 to preferentially distribute hydraulic power to the first drive component 3. At this time, the first hydraulic actuator 7 completes the high-intensity propulsion task with the cooperation of the first pressure regulator. When the drilling rig host switches to low-speed precision mode, the main control unit 1 switches the hydraulic power to the second drive component 4 through the three-way valve 6, and the second hydraulic actuator 8 and the second pressure regulator work together to complete the high-precision operation task.

[0031] The rock stress sensor 11 monitors the changes in rock stress in the drilling area in real time and transmits the data to the auxiliary control module 10. The auxiliary control module 10 adjusts the operating parameters of the first drive assembly 3 and the second drive assembly 4 based on the received data. For example, when the rock stress is high, the auxiliary control module 10 reduces the advance speed of the first drive assembly 3 and increases the hydraulic pressure of the second drive assembly 4, thereby improving drilling accuracy. The temperature sensor 12 monitors the oil temperature changes in the hydraulic system. When the oil temperature is too high, the auxiliary control module 10 reduces the load on the hydraulic system to avoid equipment performance degradation or malfunction due to overheating.

[0032] The safety protection module analyzes data from the environmental perception module 9 to determine if there are potential risks in the current operating conditions. For example, when the rock stress exceeds a preset threshold, the safety protection module automatically triggers the near-field communication module to send a warning signal to the operator and simultaneously adjusts the operating status of the first drive component 3 and the second drive component 4 to reduce the propulsion force to prevent equipment damage or accidents. The alarm module is directly connected to the main control unit 1. When the system detects abnormal conditions, such as hydraulic pressure imbalance or jamming of the three-way valve 6, the alarm module will remind the operator to handle the problem promptly through audible and visual signals.

[0033] The remote interaction module allows operators to interact with the main control unit 1 via a wireless network. Operators can use the module to view the drilling rig's operating status in real time, such as parameters like hydraulic pressure, feed rate, and rock stress, and remotely adjust operating parameters. For example, under complex geological conditions, operators can adjust the operating parameters of the first drive component 3 and the second drive component 4 via the remote interaction module, thereby improving the system's adaptability and operational efficiency.

[0034] In this embodiment, the intelligent propulsion system for coal mine drilling rigs receives the working status information of the drilling rig host through the main control unit 1. Combined with the real-time feedback from the environmental perception module 9, it flexibly distributes hydraulic power to the first drive component 3 and the second drive component 4 using the three-way valve 6, thereby meeting the propulsion needs under different working conditions. This design not only improves the adaptability of the drilling rig under complex geological conditions but also significantly enhances the system's response speed and operational accuracy, effectively solving the problem of insufficient intelligence in traditional propulsion systems.

[0035] To enable those skilled in the art to fully understand and implement this invention, the specific implementation principle of this invention will be further explained below in conjunction with a specific application scenario.

[0036] First, after the drilling rig starts, the main control unit 1 receives the working status information of the drilling rig and sends control commands to the power switching module 2 according to the current working conditions. The three-way valve 6 in the power switching module 2 adjusts the hydraulic oil flow direction according to the commands from the main control unit 1, thereby distributing hydraulic power to the first drive assembly 3 or the second drive assembly 4. For example, when the drilling rig is in high-speed propulsion mode, the main control unit 1 controls the three-way valve 6 to preferentially distribute hydraulic power to the first drive assembly 3. At this time, the first hydraulic actuator 7 operates at a higher hydraulic pressure under the action of the first pressure regulator to complete the high-intensity propulsion task. The feedback acquisition module 5 collects the operating data of the first hydraulic actuator 7 and the first pressure regulator in real time and transmits this data to the main control unit 1 so that the main control unit 1 can dynamically adjust the control strategy according to the actual operating conditions.

[0037] Subsequently, a rock stress sensor 11 is installed near the drill bit to monitor changes in rock stress in the drilling area in real time. When the rock stress is high, the rock stress sensor 11 transmits relevant data to the auxiliary control module 10. After analyzing the received data, the auxiliary control module 10 adjusts the operating parameters of the first drive assembly 3 and the second drive assembly 4. For example, the auxiliary control module 10 reduces the advance speed of the first drive assembly 3 while increasing the hydraulic pressure of the second drive assembly 4 to improve drilling accuracy. A temperature sensor 12 is installed in the oil circuit of the hydraulic system to monitor changes in the temperature of the hydraulic oil. When the temperature sensor 12 detects that the hydraulic oil temperature is too high, the auxiliary control module 10 reduces the load on the hydraulic system to prevent equipment performance degradation or malfunction due to overheating.

[0038] Under complex geological conditions, the safety protection module analyzes data from the environmental perception module 9 to determine if there are potential risks in the current working conditions. For example, when the rock stress exceeds a preset threshold, the safety protection module automatically triggers the near-field communication module to send a warning signal to the operator. Simultaneously, the safety protection module adjusts the operating status of the first drive component 3 and the second drive component 4, reducing the propulsion force to prevent equipment damage or accidents. Furthermore, the alarm module is directly connected to the main control unit 1. When the system detects abnormal conditions, such as hydraulic pressure imbalance or jamming of the three-way valve 6, the alarm module alerts the operator with audible and visual signals to address the problem promptly.

[0039] The remote interaction module allows operators to interact with the main control unit 1 via a wireless network. In practical applications, operators can use the remote interaction module to view the drilling rig's operating status in real time, such as parameters like hydraulic pressure, feed rate, and rock stress. Operators can also remotely adjust the operating parameters of the first drive assembly 3 and the second drive assembly 4 to adapt to different geological conditions. For example, when encountering soft rock formations, operators can reduce the feed rate of the first drive assembly 3 and appropriately reduce the hydraulic pressure of the second drive assembly 4 to avoid deviations during drilling.

[0040] Finally, when the drilling rig switches to low-speed precision mode, the main control unit 1 switches the hydraulic power to the second drive component 4 via the three-way valve 6. At this time, the second hydraulic actuator 8, in coordination with the second pressure regulator, operates at a lower propulsion speed to complete the high-precision operation. The feedback acquisition module 5 collects the operating data of the second hydraulic actuator 8 and the second pressure regulator in real time and transmits this data to the main control unit 1 so that the main control unit 1 can further optimize the control strategy. In this way, the intelligent propulsion system of the coal mine drilling rig can flexibly respond to the propulsion needs under different working conditions, significantly improving the system's response speed and operating accuracy.

[0041] In summary, the intelligent propulsion system for coal mine drilling rigs provided in this embodiment of the invention receives the working status information of the drilling rig host through the main control unit 1, and combines it with the real-time feedback from the environmental perception module 9. It then uses a three-way valve 6 to flexibly distribute hydraulic power to the first drive component 3 and the second drive component 4, thereby meeting the propulsion needs under different working conditions. This design not only improves the adaptability of the drilling rig under complex geological conditions but also significantly enhances the system's response speed and operational accuracy, effectively solving the problem of insufficient intelligence in traditional propulsion systems.
