Description

Technical Field

[0001] This utility model relates to a leveling device for a tunneling machine, belonging to the field of mining machinery technology. Background Technology

[0002] Cantilever tunneling machines are a crucial component of coal mine roadway excavation, integrating rock cutting, material collection, and transportation functions. Due to varying geological conditions, rock hardness also changes. In existing hard rock tunneling machine technology, the machine's levelness can only be adjusted manually. This adjustment method is not only inefficient but also cannot accurately adapt to the dynamic changes in the roadway floor. Furthermore, unstable machine levelness affects the accuracy of the excavation direction, reducing excavation efficiency and potentially causing significant errors in the roadway excavation direction, requiring subsequent correction work and increasing labor and time costs. To address these issues, a tunneling machine leveling maintenance device has emerged. This device automatically adjusts the extension and retraction of the rear support legs and the shovel and tracks based on changes in the tunneling machine's levelness, thereby ensuring optimal cutting results. The background technology of tunneling machine leveling maintenance devices mainly involves the cutting process and methods of tunneling machines, the dynamic changes in cutting load, and the problems existing in current technologies. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a leveling device for a tunneling machine. This device can monitor the pitch and roll angles of the tunneling machine in real time, ensuring the stability of the machine's level, thereby avoiding errors in the tunneling direction and improving tunneling efficiency.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] This utility model provides a leveling device for a tunneling machine, comprising:

[0006] Sensor assembly: Composed of a high-precision angle gauge and an accelerometer, responsible for detecting changes in the angle of the tunneling machine body.

[0007] Control system: including electrical control box and controller, used to receive signals from sensor components and output control commands.

[0008] Adjustment mechanism: including hydraulic cylinders or electric push rods, connected to the support legs or track system of the tunneling machine.

[0009] Display alarm module: used to display the level status of the tunneling machine in real time and issue an alarm when it deviates from the set range.

[0010] The tunnel boring machine's leveling device primarily relies on a high-precision angle gauge and accelerometer, a PLC controller, and a display. The high-precision angle gauge and accelerometer are connected to the PLC controller via cables, and the PLC controller is connected to the display via cables. The high-precision angle gauge and accelerometer are used to detect the tunnel boring machine's pitch and roll angles in real time, transmitting the detected data to the PLC controller. The PLC controller processes the received data, calculates the tunnel boring machine's current leveling, and sends the result to the display. The PLC controller can also adjust the tunnel boring machine's operation based on a preset leveling threshold. If the machine's posture exceeds the preset threshold, the display will issue an alarm, and the controller will simultaneously adjust the tunnel boring machine's operation to maintain stable leveling.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0012] High-precision real-time monitoring:

[0013] The device uses a high-precision angle meter and accelerometer to monitor the pitch and roll angles of the tunnel boring machine in real time and accurately, ensuring the stability and reliability of the measurement data even under complex and variable geological conditions.

[0017] The controller has self-learning capabilities, enabling it to continuously accumulate operational data, optimize and adjust strategies, and improve control accuracy and response speed.

[0018] Highly efficient and stable implementing mechanism:

[0019] The actuator uses a reliable hydraulic cylinder or electric push rod, which has strong adjustment capabilities and fast response speed. It can accurately execute the instructions of the PLC controller, adjust the support structure of the tunneling machine, and maintain the stability of the machine body level.

[0020] The design of the actuator fully considers the weight distribution of the tunneling machine and the operating environment, ensuring stable operation even under harsh conditions and improving the efficiency and safety of tunneling operations.

The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0034] Examples, such as Figure 1 and Figure 2 As shown in the figure, this embodiment introduces a leveling device for a tunneling machine, including: a sensor assembly, a control system, an adjustment mechanism, and a display and alarm module.

[0035] The sensor assembly includes a high-precision angle meter and an accelerometer, and the control system includes an electrical control box and a PLC controller, wherein the sensor assembly is electrically connected to the controller of the electrical control box.

[0036] The sensor assembly further includes a high-precision angle meter and an accelerometer for levelness detection during tunneling operations, while the control system includes an electrical control box and a controller for controlling and monitoring the overall operation of the tunneling machine.

[0037] The control system compares the real-time measurement values ​​of the high-precision angle meter and accelerometer with the preset values ​​in the controller, and adjusts the mechanism to perform actions to achieve horizontal deviation correction.

[0038] The angle meter and accelerometer are highly sensitive and accurate, capable of accurately capturing subtle changes in the attitude of the tunneling machine and converting these changes into electrical signals for transmission in real time.

[0039] The controller in the electrical control box has a built-in self-adjusting algorithm that can intelligently adjust the support legs or track system of the tunneling machine based on the real-time vehicle body angle data transmitted by the sensor components. When the vehicle body is detected to be tilting forward or backward, the controller will automatically extend or retract the rear support leg cylinders or shovels and tracks to maintain the vehicle body's levelness. This self-adjusting mechanism can ensure that the tunneling machine maintains stable operation under different rock hardness conditions.

[0040] Initial settings:

[0041] Before the tunneling machine starts working, the electronic control system is initially set up, including setting control parameters and calibrating sensors. A levelness threshold is preset based on the vehicle's attitude and levelness.

[0042] Real-time monitoring:

[0043] After the tunneling machine starts working, the sensor assembly monitors the changes in the angle of the tunneling machine body in real time and transmits the monitored signals to the controller of the electronic control system for processing and analysis.

[0044] Signal processing:

[0045] The controller processes the received signals through filtering, noise reduction, and feature extraction. Based on the processing results, it determines the current attitude of the tunneling machine.

[0046] Adaptive adjustment:

[0047] Based on the preset speed control strategy and algorithm, as well as the current body posture and levelness of the tunneling machine, the rear support and shovel track of the tunneling machine are adaptively adjusted to ensure that the body levelness is stable within the set range.

[0048] Feedback Adjustment:

[0049] During the adaptive adjustment process, the control system continuously monitors the tunneling machine's attitude and levelness. It continuously optimizes and adjusts based on actual conditions, enabling the tunneling machine to maintain optimal operating performance under varying rock hardness and load conditions.

[0050] In summary, the tunneling machine leveling device provided by this utility model exhibits significant technical advantages in terms of high-precision real-time monitoring, intelligent adaptive control, efficient and stable actuators, user-friendly human-machine interface, remote monitoring and management capabilities, and strong adaptability and scalability.
