Description

Technical Field

[0001] This invention relates to the field of tunnel boring machine main drive monitoring technology, and in particular to a tunnel boring machine main drive oil monitoring device, system and method. Background Technology

[0002] Tunnel boring machine (TBM) technology plays a vital role in underground engineering construction. The main drive seal, acting as the TBM's immune system, is crucial for blocking external media and is a key factor in ensuring the safe operation of the equipment. Wear and tear on the seal can lead to system failure, manifesting in various ways such as impurities entering the sealing cavity and gear oil leakage into the detection chamber. Current technologies often rely on sampling oil from different chambers to determine if impurities have entered, which is time-dependent and requires highly skilled personnel on site.

[0003] The existing main drive sealing system of tunneling machines typically consists of multiple rubber seals combined with sealing chambers, which are then continuously extruded with grease to achieve a sealing effect. In this process, grease is usually injected into the first two sealing chambers, gear oil into the third, and the fourth sealing chamber is used as a detection chamber without any grease. In actual use, if the front-end seal fails, allowing mud and impurities to enter the third sealing chamber, this cannot be detected in time. This can easily lead to abnormal particle wear between the third seal and the track, causing the sealing system to fail. Even worse, if the third seal fails, oil can directly enter the detection chamber, and since the fourth seal lacks the ability to seal the oil in the detection chamber, the oil can directly enter the main bearing, damaging the entire main drive system.

[0004] Currently, most methods, such as monitoring sensors, are used to monitor the main drive oil of tunnel boring machines. However, sensors are easily affected by external environmental interference, which can lead to misjudgments and make it difficult to analyze the phenomena intuitively. Summary of the Invention

[0006] The housing, the image acquisition element integrated within the housing, the oil pump, and the transparent tube, among which,

[0007] The first end of the transparent tube is connected to the oil inlet of the shell, and the second end of the transparent tube is connected to the oil outlet of the shell. The oil in the gear oil chamber of the main drive of the tunnel boring machine enters from the oil inlet, passes through the transparent tube, and flows back to the gear oil chamber of the main drive of the tunnel boring machine from the oil outlet.

[0008] The oil pump is used to drive the oil to flow in the transparent tube, so that the oil circulates in the gear oil chamber of the main drive of the tunnel boring machine.

[0009] The image acquisition element is used to acquire image data of the oil inside the transparent tube, analyze the state of the oil, and generate alarm information.

[0010] This invention proposes a main drive oil monitoring system for tunnel boring machines (TBMs) to monitor the main drive oil of TBMs. The system is not easily affected by external environmental interference, and is intuitive and accurate. The system includes:

[0012] The first hydraulic pipe is connected to the first hole of the grease ring of the main drive of the tunnel boring machine and the oil inlet of the main drive oil monitoring device of the tunnel boring machine, respectively, for oil to flow from the gear oil chamber of the first hole into the oil inlet. The first hole is connected to the gear oil chamber of the main drive of the tunnel boring machine.

[0013] The second hydraulic pipe is connected to the second hole of the grease ring of the main drive of the tunnel boring machine and the oil outlet of the main drive oil monitoring device of the tunnel boring machine, respectively. The oil flows out from the oil outlet and flows into the gear oil chamber after passing through the second hole. The second hole is connected to the gear oil chamber of the main drive of the tunnel boring machine.

[0014] The image acquisition element in the main drive oil monitoring device of the tunnel boring machine is also used to: send alarm information to the host computer;

[0015] The host computer is used to display alarm information.

[0016] This invention proposes a method for monitoring the main drive oil of a tunnel boring machine (TBM). This method is less susceptible to external environmental interference, and is intuitive and accurate. The method includes:

[0017] Image data of the main drive fluid of the tunnel boring machine inside the transparent tube;

[0018] The state of the oil is obtained by analyzing the image data;

[0019] When the image data is the data of the oil in the gear oil chamber of the main drive of the tunnel boring machine, if the state of the oil is that there are foreign objects other than gear oil, an alarm message for gear oil contamination will be issued; if the state of the oil is that the oil level in the transparent tube has dropped, an alarm message for low gear oil chamber level will be issued.

[0020] When the image data is the data of the oil in the detection chamber of the tunnel boring machine's main drive, if the oil status shows that there is liquid level in the transparent tube, an alarm message for oil leakage in the detection chamber will be issued.

[0021] This invention also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor.

When the processor executes the computer program, it implements the above-described method for monitoring the main drive oil of a tunnel boring machine.

[0024] This invention also provides a computer program product, which includes a computer program that, when executed by a processor, implements the above-described method for monitoring the main drive oil of a tunnel boring machine.

[0025] In this embodiment of the invention, the image acquisition element can acquire images of the oil flowing inside the transparent tube, obtaining image data for subsequent analysis of the oil level and impurities. Since the inside of the tunnel boring machine's main drive oil monitoring device is dark, a light source is beneficial for image acquisition. In addition, the oil pump can drive the oil to flow inside the transparent tube, allowing the oil to circulate within the gear oil chamber of the tunnel boring machine's main drive. Only flowing oil can provide accurate monitoring results. Compared with existing solutions that use sensors for monitoring, this solution introduces image recognition technology into the monitoring of the main drive oil. By analyzing real-time captured images, it can more accurately and intuitively monitor the oil status, quickly identify whether abnormalities are caused by misjudgments, greatly improve the accuracy and stability of monitoring, and better provide risk warnings for the tunnel boring machine's main drive.

[0066] In one embodiment, the system further includes a heat dissipation system for maintaining the temperature within the system below a preset temperature.

[0067] The following presents two application scenarios for the device and system proposed in this invention. Both application scenarios play a crucial role in the main drive oil monitoring system of tunnel boring machines.

[0068] Scene 1

[0069] By connecting the main drive oil monitoring device of the tunnel boring machine (TBM) in series with the gear oil chamber, and connecting the oil in the gear oil chamber to a transparent tube inside the casing, the monitoring camera can clearly capture the state of the oil in the transparent tube, thus characterizing the state of the oil in the gear oil chamber. Simultaneously, considering the phenomenon of solid particles settling to the bottom due to gravity within the sealed cavity, an oil pump is started during monitoring to circulate the oil between the gear oil chamber and the transparent tube. The flow of the oil carries away the solid particles. To save energy, the oil pump can be set to start intermittently. When solid particles pass through the transparent tube, the camera records image data of the particles (impurities) passing through and analyzes the state of the oil. If the number of solid particles is small, the camera automatically calculates the number of foreign objects (particles) in the transparent tube; if the number of particles is large, an algorithm calculates the area occupied by the particles. Based on the quantity or area, the state of the oil is determined to contain foreign objects other than gear oil. When the camera detects particles passing through the transparent tube, it captures image data and generates an alarm message for gear oil contamination, which is transmitted to the host computer interface for notification. Operators can view the stored images through historical data and also check the current oil state in real time. Meanwhile, to facilitate on-site inspection for potential misjudgments, a viewing window is installed on the casing directly opposite the transparent tube. This window is made of a wear-resistant material with a certain degree of transparency, allowing on-site personnel to analyze and troubleshoot. Additionally, if the oil level in the transparent tube decreases, an alarm message indicating a low gear oil level is issued.

[0070] Scene 2

[0071] By connecting the main drive oil monitoring device of the tunnel boring machine (TBM) in series with the sealing chamber / detection chamber, and linking the detection chamber to a transparent tube inside the casing, the monitoring results within the transparent tube characterize the oil leakage situation within the detection chamber. To detect oil leaks immediately, the oil inlet of the monitoring system should be connected to the grease hole at the bottom of the detection chamber. Simultaneously, the height of the transparent monitoring tube should be as low as possible below the plane of the grease hole at the bottom of the detection chamber. This allows oil leaks into the detection chamber immediately, flowing into the transparent tube and promptly transmitting the leakage information to the host computer. When the camera detects oil flowing into the transparent tube, it captures an image and analyzes it. If the oil level in the transparent tube indicates a leak, the camera sends an alarm message to the host computer, allowing on-site personnel to inspect the detection chamber immediately and reduce the probability of larger risks.

[0072] Therefore, this invention enables real-time monitoring of impurities in the oil within the sealed cavity and detection of oil leakage. When impurities enter the gear oil chamber of the sealed cavity, an immediate warning can be issued. As a result, by connecting the main drive oil monitoring device of the tunnel boring machine in series at different locations, real-time image data of impurities entering the oil within the sealed cavity and oil leakage can be captured and analyzed. Alarm information is then fed back to the host computer, allowing for timely risk warnings and investigations, reducing the probability of larger risks occurring.

[0073] See Figure 6 This invention also proposes a method for monitoring the main drive oil of a tunnel boring machine, comprising:

[0074] Step 601: Acquire image data of the main drive fluid of the tunnel boring machine inside the transparent tube;

[0075] Step 602: Analyze the image data to obtain the state of the oil;

[0076] Step 603: When the image data is the data of the oil in the gear oil chamber of the main drive of the tunnel boring machine, if the state of the oil is that there are foreign objects other than gear oil, an alarm message for gear oil contamination is issued; if the state of the oil is that the oil level in the transparent tube has dropped, an alarm message for low gear oil chamber level is issued.

[0077] Step 604: When the image data is the data of the oil in the detection chamber of the tunnel boring machine's main drive, if the state of the oil is that there is liquid level in the transparent tube, an alarm message for oil leakage in the detection chamber is issued.

[0078] The apparatus, system, and method proposed in the embodiments of the present invention have the following beneficial effects:

[0079] The camera can capture images of the oil flowing inside the transparent tube, obtaining image data for subsequent analysis of oil level and impurities. Since the inside of the tunnel boring machine's main drive oil monitoring device is dark, a light source is beneficial for image acquisition. Furthermore, the oil pump drives the oil to flow within the transparent tube, allowing it to circulate within the gear oil chamber of the tunnel boring machine's main drive. Only flowing oil can provide accurate monitoring results. Compared to existing sensor-based monitoring solutions, this solution introduces image recognition technology into the main drive oil monitoring. By analyzing real-time captured images, it can more accurately and intuitively monitor the oil status, quickly identify abnormalities caused by misjudgments, and significantly improve the accuracy and stability of monitoring, providing better risk warnings for the tunnel boring machine's main drive.
