[0042] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0043] The finished product of the steel bar is braked at the end of the rolling production line and thrown from the production line into the cooling bed. Specifically, the finished product needs to be sent to the apron and friction-braked with the surface of the apron to reduce the speed. After the product is completely braked, it rises to a high position to complete the process of discharging the steel. Among them, the hydraulic apron refers to an apron system that controls the rise and fall of the apron through hydraulic pressure. After long-term use, multiple components of the hydraulic apron will be severely worn. Therefore, it is necessary to conduct fixed-point and regular inspections (hereinafter referred to as "spot inspections", including but not limited to collecting pressure, oil temperature, and liquid level) on each component of the hydraulic apron. At present, the spot inspection of the hydraulic apron mainly relies on inspection personnel, resulting in problems such as a large amount of repetitive work and low inspection efficiency.

[0044] In view of this, the embodiments of the present invention provide a monitoring system and repair method for a hydraulic apron that can solve the above problems, and will be described in detail below.

[0045] Before elaborating on the monitoring system of the embodiments of the present invention in detail, briefly introduce the hydraulic apron 4. The hydraulic apron 4 in the embodiments of the present invention includes a hydraulic system and an actuator. Among them, the hydraulic system includes various hydraulic pipelines, a hydraulic station, and various valves provided on the hydraulic pipelines. The hydraulic station is provided with a hydraulic oil tank, and the hydraulic pipelines are connected to the hydraulic oil tank to form a circulation loop. The hydraulic system also has an electrical room and a transformer room for controlling valves, pumps, and detection elements.

[0046] Reference Figure 2, the actuator includes a hydraulic cylinder 401, a support rod 402, a skirt plate 403, a lever 404, a main shaft 405 and a swing rod 406. The hydraulic cylinder 401 is connected and communicated with a hydraulic pipeline. The reciprocating movement of the rod of the hydraulic cylinder 401 is controlled by injecting or pumping out hydraulic oil into the hydraulic cylinder 401. One end of the rod of the hydraulic cylinder 401 is rotatably connected to one end of the lever 404, and the other end of the lever 404 is rotatably connected to the main shaft 405. One end of the swing rod 406 is also rotatably connected to the main shaft 405, and the other end of the swing rod 406 is rotatably connected to the support rod 402. The support rod 402 is movably connected to the skirt plate 403. When the hydraulic oil in the hydraulic cylinder 401 is discharged, the rod of the hydraulic cylinder 401 retracts, the rod of the hydraulic cylinder 401 pulls the lever 404 to rotate upward, the lever 404 drives the main shaft 405 to rotate clockwise by an angle, the main shaft 405 drives the swing rod 406 to rotate, and the end of the swing rod 406 connected to the support rod 402 moves downward, thereby pulling the support rod 402 downward. The support rod 402 pulls the skirt plate 403 downward, and the skirt plate 403 completes the descent. Conversely, when the rod of the hydraulic cylinder 401 extends, the skirt plate 403 completes the ascent.

[0047] Please refer to Figure 1 , the monitoring system of the hydraulic skirt plate 4 includes: a data acquisition layer 1, an operation and maintenance platform layer 2 and an application management layer 3. The data acquisition layer 1 acquires the operation parameters of different components of the hydraulic skirt plate 4. The operation and maintenance platform layer 2 is communicatively connected to the data acquisition layer 1, and the application management layer 3 is communicatively connected to the operation and maintenance platform layer 2. The data acquisition layer 1 performs real-time detection on different components of the hydraulic skirt plate 4, and at the same time transmits the detected data to the operation and maintenance platform layer 2. The operation and maintenance platform layer 2 decodes and converts the data and then transmits it to the application management layer 3. The application management layer 3 analyzes the data and displays the results for judgment and use. The data acquisition layer 1, the operation and maintenance platform layer 2 and the application management layer 3 cooperate together to replace the existing manual spot check, solve the problems of heavy repetitive workload and low inspection efficiency of manual spot check, and have the advantages of high efficiency and high reliability.

[0048] In the embodiment of the present invention, the monitoring system adopts a hierarchical architecture design. The data acquisition layer 1, the operation and maintenance platform layer 2 and the application management layer 3 are sequentially connected by wired or wireless communication means to realize the full-process automation of data from acquisition, transmission to analysis and processing.

[0049] Among them, the data acquisition layer 1 is the front-end perception unit of the monitoring system, which is composed of a variety of sensors and an image acquisition device 104, and is directly deployed at the key parts of the hydraulic skirt plate 4.

[0050] Specifically, the data acquisition layer 1 includes a temperature sensor 101, a liquid level sensor 102 and a pressure sensor 103.

[0051] The temperature sensor 101 is installed on the outer wall of the hydraulic oil tank of the hydraulic station to monitor the temperature of the oil in the hydraulic oil tank in real time. The temperature sensor 101 is encapsulated with high-temperature resistant materials, converts the temperature signal into an electrical signal through the thermocouple principle, has a sampling frequency of 1 time per second, and an accuracy of ±0.5°C.

[0052] The liquid level sensor 102 is embedded inside the hydraulic oil tank and uses a float type or ultrasonic type to detect the height of the oil liquid level. When the liquid level is lower than the preset threshold (such as 30% of the tank height), a low liquid level warning is triggered.

[0053] The pressure sensor 103 is installed on the pump outlet pipeline of the hydraulic station to monitor the real-time pressure at the pump outlet. The pressure sensor 103 is selected with a piezoresistive design, has a measuring range of 0 - 40 MPa, and an output signal of 4 - 20 mA, an analog current signal.

[0054] The data acquisition layer 1 also includes multiple image acquisition devices 104. The multiple image acquisition devices 104 are respectively arranged at the hydraulic cylinder 401, the skirt plate 403, and the support rod 402, and the multiple image acquisition devices 104 are communicatively connected to the operation and maintenance platform layer 2.

[0055] The image acquisition device 104 includes a high-definition camera and an infrared thermal imager, which are respectively deployed at key positions such as the hydraulic cylinder 401, the skirt plate 403, the support rod 402, the electrical room, and the transformer room. The camera is fixed in the protective cover by bolts, has dust and waterproof functions, supports a resolution of 1080P and real-time video transmission of 30 frames per second; the infrared thermal imager is used to detect the surface temperature distribution of the hydraulic cylinder 401 and identify local overheating anomalies.

[0056] All sensors and the image acquisition device 104 are connected to the operation and maintenance platform layer 2 through the RS-485 bus or industrial Ethernet, and the data is encapsulated in the Modbus protocol and uploaded.

[0057] Continue to refer to Figure 1 , the operation and maintenance platform layer 2 consists of multiple relay devices 201, adopts a distributed deployment mode, and each relay device 201 is responsible for receiving and preprocessing the signals of the data acquisition layer 1 in a specific area.

[0058] The operation and maintenance platform layer 2 realizes data decoding and format conversion. For example, it converts the analog signals or digital signals uploaded by each sensor into the standard JSON format and adds metadata such as timestamps and device IDs. The operation and maintenance platform layer 2 can also realize data caching and redundant backup. For example, it uses the circular buffer technology to temporarily store data to avoid data loss caused by network interruptions, and at the same time backs up the key data to the cloud storage server 302. The operation and maintenance platform layer 2 can also realize abnormal data filtering. For example, it uses the sliding window algorithm to identify and eliminate noise data (such as the instantaneous spike of the pressure sensor 103) to ensure data reliability.

[0059] The relay device 201 is connected to the server 302 of the application management layer 3 via optical fiber or 5G network, supporting two-way communication. For example, when the server 302 issues a control instruction (such as adjusting the camera angle), the relay device 201 forwards it to the corresponding device for execution.

[0060] The application management layer 3 is the core analysis and display unit of the system, consisting of a monitoring platform 301, multiple servers 302, and terminal devices 303.

[0061] Specifically, the multiple servers 302 adopt a cluster architecture, and each server 302 independently undertakes a specific functional module. For example, the first server 302 is responsible for storing historical data, the second runs machine learning algorithms to analyze the correlation between temperature and pressure, and the third processes image data and calls an AI model to identify cracks in the support rod 402. Tasks are dynamically allocated among the servers 302 through load balancing technology to ensure high availability of the system.

[0062] The monitoring platform 301 is developed based on Web technology, providing a visual interface (such as dashboards, 3D model views). Operators can view the hydraulic oil tank liquid level curve, pump outlet pressure fluctuation trend, and monitoring images of each camera in real time through the interface. The platform supports multi-level permission management, and administrators can configure alarm thresholds (such as triggering a first-level alarm when the oil temperature exceeds 80°C).

[0063] The terminal devices 303 include industrial computers in the factory control center and mobile terminals (tablet computers or mobile phones) of engineers. The terminals communicate with the server 302 via the HTTPS protocol, receive alarm pushes (such as text messages or APP notifications), and remotely retrieve detailed data of faulty components.

[0064] The monitoring system is also provided with alarms (not shown), and the alarms adopt audible and visual alarms. Multiple alarms are respectively installed around the hydraulic station and in the control center.

[0065] When the application management layer 3 detects the following abnormalities, it immediately triggers an alarm. For example, the oil temperature continuously exceeds 85°C for 5 minutes; the pump outlet pressure is lower than 10 MPa or higher than 35 MPa; the image analysis identifies that the surface crack length of the support rod 402 exceeds 2 mm. The alarm signal is sent from the application management layer 3 to the relay device 201, which controls the alarm to give an audible and visual prompt, and at the same time sends fault location information to the terminal device 303.

[0066] The monitoring system of the embodiment of the present invention realizes fully automated monitoring. The data acquisition layer 1 real-time collects temperature, pressure, liquid level, and image data of the hydraulic system, replacing traditional manual inspections, and the inspection efficiency is increased by more than 80%. Moreover, the application management layer 3 can also predict the hydraulic oil life and pump valve wear trend through a machine learning model, generate a maintenance plan in advance, and reduce unplanned downtime.

[0067] Of course, in order to protect the hydraulic system, an accumulator can also be provided in the hydraulic station to reduce the damage of the hydraulic fluid to the hydraulic pipeline.

[0068] When the hydraulic skirt plate 4 is used for a long time, wear will occur in each component. The most common one is that the support rod 402 undergoes strain inside during reciprocating motion, and its stress exceeds the material strength limit, resulting in fatigue fracture. When the monitoring system detects damage to the support rod 402 (such as identifying cracks through image analysis), rapid repair is required.

[0069] Therefore, the embodiments of the present invention also provide a repair method, which will be described below by taking the repair of the support rod 402 as an example. Of course, this repair method can also be used to repair other components of the liquid-cooled skirt plate 403.

[0070] A repair method for the support rod 402 of the liquid-cooled skirt plate 403 includes the following repair processes:

[0071] Step 1: Disassemble the damaged support rod 402. The operator retrieves the high-definition image and infrared thermal imaging map of the damaged support rod 402 through the monitoring platform 301 to confirm the crack position and severity. If the crack length exceeds the safety threshold (such as 2 mm), the system automatically generates a disassembly work order.

[0072] The operator uses a hydraulic lifting platform to approach the support rod 402 and removes the connecting bolts at its two ends to the skirt plate 403 and the swing rod 406. During the disassembly process, the operation safety is monitored in real time through the image acquisition device 104 to avoid accidentally touching other components.

[0073] Step 2: Wind an anti-corrosion fixing tape on the outside of the damaged part of the support rod 402. Clean the oil stain and rust on the surface of the support rod 402, and use sandpaper to polish the area around the crack until the metal matrix is exposed; wind three or more layers of epoxy resin-based anti-corrosion fixing tape (band width 50 mm) along the axial direction at the crack, with each layer overlapping by 50%, and apply a constant tension (about 10 N) during winding to ensure that the tape is tightly attached to the rod body.

[0074] Step 3: Place the support rod 402 wound with the anti-corrosion fixing tape into the sleeve, and pour grouting material into the gap between the sleeve and the support rod 402.

[0075] Insert the wound support rod 402 into a prefabricated carbon steel sleeve (inner diameter slightly larger than the rod diameter), leaving a 20-mm gap at both ends of the sleeve. Use a high-pressure grouting machine to inject non-shrink grouting material (such as cement-based composite material) into the annular gap between the sleeve and the support rod 402, controlling the grouting pressure at 0.5 - 0.8 MPa to ensure dense filling of the slurry. Of course, high-polymer damping composite material IMCD4618 can also be used for grouting. After grouting, let it stand for 24 hours until it is completely cured.

[0076] Step Four: After the grouting material is formed, perform quenching and tempering treatment on the entire formed support rod 402.

[0077] Place the entire repaired support rod 402 into a heat treatment furnace, first heat it to 850 °C and hold for 1 hour (austenitization), then quench it in oil to room temperature, and then temper it to 550 °C and hold for 2 hours. This process can improve the comprehensive mechanical properties of the rod body.

[0078] Step Five: Detect the performance parameters of the entire formed support rod 402.

[0079] After quenching and tempering, use an ultrasonic flaw detector to detect internal defects in the repaired area, and test its tensile strength (≥600 MPa) and fatigue life (number of cyclic loads ≥ 10^6 times) through a universal testing machine. Upload the test data to the application management layer 3, compare it with the historical records, and confirm that it is qualified for repair before reinstalling and using it.

[0080] The repair method of the embodiment of the present invention combines image diagnosis and material strengthening technology. The service life of the repaired component can reach more than 90% of that of a new product, which can significantly reduce the spare part replacement cost.

[0081] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
