Description

Technical Field

[0001] This invention belongs to the field of mine hoisting equipment maintenance technology, and more specifically, it relates to an intelligent safety repair system and method for extra-large mine skip drum side. Background Technology

[0002] With the construction of large-scale intelligent mines, the use of large hoisting containers will increase, leading to a more pronounced problem of lining bulging. The problems mainly include unreasonable cross-sectional design of the hoisting container, prolonged exposure to continuous impacts, reduced strength of the liner due to wear, and creep under long-term high pressure. These factors collectively exacerbate lining bulging, posing a challenge to the safety of mine hoisting systems.

[0003] Currently, there is a lack of effective automated solutions for addressing skip bulging issues in the market, and the industry primarily relies on traditional manual repair methods. This method requires workers to enter the skip and pull it inwards, followed by external reinforcement and temporary repairs. However, the interior space of the skip is confined, making it impossible for large repair tools to enter. Workers must use rope ladders to access the skip, which is tens to twenty meters high, for suspended operations. During this process, workers not only face the risk of falls from height but also must guard against falling materials and the accidental opening of the skip's bottom gate, making the operation extremely unsafe.

[0004] Furthermore, the repair effectiveness of traditional manual repair methods is quite limited. Due to limited operating conditions, the repaired skip has poor consistency with the original structure, and in some cases, it may even cause local twisting and deformation of the skip. This cannot fundamentally solve the skip bulging problem, leading to frequent skip repairs and further increasing the mine's operating costs and downtime. Summary of the Invention

Under the supervision of the personnel, the control system, together with the skip shape adjustment system, reshapes the skip. The control system controls the hydraulic system to adjust the skip according to the signals provided by the adjustment system.

[0010] Preferably, the contact sensor can determine whether the cylinder piston is in contact with the skip body, the displacement sensor measures the extension length of the mechanical actuator, and the profile dimension sensor detects the profile dimension of the skip. When the control system sends a shaping signal, the loop shape adjustment system is activated.

[0011] Preferably, it also includes an early warning system, which is controlled by the control system and is used to issue warnings for abnormal loop shape. When the early warning system detects an abnormal loop shape, the control system issues a warning immediately.

[0012] Furthermore, the present invention also provides an intelligent safety repair method for the skip drum side of an extra-large mine, which is carried out through the above-mentioned intelligent safety repair system to achieve skip shape adjustment and improve the safety of the mine hoisting system.

[0013] Preferably, the method includes: When the recognition system and sensor system detect that the shape and size of the basket have reached a predetermined value, the control system sends an early warning signal to the staff. After the staff checks the information on the shape and size of the basket collected by the recognition system and the trimming system, they confirm that the shape and size of the basket have exceeded the limit and then trim the shape of the basket. The trimming mode includes automatic trimming mode and manual intervention mode. The automatic trimming mode includes: the control system intelligently controls the action of the loop shape trimming system to trim the loop shape based on the shape information of the loop collected by the identification system and the trimming system.

Detailed Implementation

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] Example 1 Please see Figure 1 This invention provides an intelligent safety repair system for extra-large mine skip drum sides, comprising: Control system 1, which includes computer 11, computer software and PLC control system 12; Recognition System 2, which is equipped with an image recognition unit for real-time monitoring of the shape of the winnowing basket; The skip shape adjustment system 3 and the skip execution system 3 are equipped with an end effector system 31, which includes a hydraulic cylinder array 311 and a hydraulic system 312. The end effector system also includes a power system 32 and a sensor system 33, which includes a contact sensor 331, a displacement sensor 332, and a contour dimension sensor 333.

[0021] The intelligent safety repair system for skip bulging in extra-large mines provided in this embodiment of the invention offers high safety. This system eliminates the need for manual entry into the skip for repair work, fundamentally eliminating safety risks such as falls from heights, material impact injuries, and accidental gate opening faced by workers entering hazardous areas, thus ensuring the personal safety of personnel. Furthermore, the system collects skip morphology image data through the recognition system 2, and combines this with the sensor system 33 in the skip morphology repair system 3 to achieve dual data monitoring, accurately acquiring skip morphology information. The control system 1 intelligently controls the skip morphology repair system based on the data information, achieving precise repair of the skip bulging sides. After repair, the skip maintains a high degree of consistency with the original structure, effectively avoiding the local twisting and deformation problems caused by traditional manual repairs, and significantly improving the repair effect. This embodiment, through precise and effective repair, can prevent the skip from aging rapidly due to bulging sides, significantly extending the skip's service life. Simultaneously, it reduces mine downtime caused by excessively long manual maintenance times and frequent skip replacements, saving mine operating costs and providing strong support for the long-term stable operation of extra-large intelligent mines.

[0022] In this embodiment, as Figure 1 As shown, the control system 1 is equipped with a computer 11, computer software and a PLC control system 12. The computer 11 and its computer software are used to process the data transmitted by the identification system 2 and the skip shape trimming system 3, and control the PLC control system 12 to drive the end effector 31 of the skip shape trimming system 3 to automatically trim the skip.

[0023] Specifically, computer 11 is equipped with dedicated software and is an explosion-proof computer. Computer 11 processes the data transmitted by the skip identification system and the skip trimming system, and controls the PLC control system 12 to drive the skip shape trimming system 3 to automatically trim the skip. The end effector system 31 has on-site control function and can be directly operated on-site. It is used by workers to manually control the on-site hydraulic system to achieve the purpose of trimming the skip.

[0024] In this embodiment, when deploying the control system, the computer is first installed in a suitable area of ​​the mine to ensure that it can operate stably and receive data transmitted by each system. The operation panel of the field control system is set up in the field operation area. The operation panel is connected to the hydraulic control system end effector system to facilitate the operator to manually control the action of the end effector system on site. The control system 1 is connected to each unit by wiring and software debugging to ensure smooth data transmission and collaborative work between the systems.

[0025] In this embodiment, the image recognition unit employs an AI image recognition system, including: The high-definition camera 21 can provide full coverage of the basket rising at a speed of 0.5-1.5m / s; Deep learning algorithms are used to learn the initial form of the loop and establish a normal form model.

[0026] Furthermore, the HD camera 21 uses a high-definition camera that is shockproof, dustproof, and waterproof to adapt to the complex working environment downhole.

[0027] In this embodiment, high-definition cameras 21 are reasonably deployed on the main shaft wall and the headframe around the skip to ensure that the cameras can cover the skip being lifted at a speed of 0.5-1.5 m / s throughout the entire process, thereby capturing clear and real-time images of the skip's shape. The specific number and location of the high-definition cameras 21 can be adapted and adjusted according to the actual working conditions. The high-definition cameras 21 are connected to the computer through a data transmission line to ensure that the image data can be stably transmitted to the computer system.

[0028] Furthermore, such as Figures 2-4 As shown, the skip shape correction system 3 is set on both sides of the skip well frame and is used to adjust the shape of the skip. The skip shape correction system 3 is equipped with an end effector system 31, a power system 32 and a sensor system 33. When the identification system 2 detects that the shape and size of the basket exceed the limit, the computer issues a reminder to the relevant staff. Under the supervision of the staff, the control system cooperates with the basket shape adjustment system 3 to reshape the basket. The computer 11 in the control system 1 drives the PLC control system 12 to drive the basket shape adjustment system 3 to act, and adjusts the basket according to the signals provided by the sensor system 33 of the adjustment system.

[0029] Furthermore, preferably, the end effector 31 is a mechanical effector system for adjusting the shape of the skip, the mechanical effector system includes a power system and an end effector, the end effector includes a hydraulic system and its actuator, etc.

[0030] Specifically, the end effector system 31 is equipped with a shaping cylinder array. The shaping cylinders are arranged symmetrically on both sides of the skip wellbore frame to ensure that the cylinder pistons can accurately act on the skip drum side when they extend. The shaping cylinders are connected to the hydraulic system, which is connected to the PLC control system 12 and the computer 11 to realize the control system 1 to control the extension and retraction of the shaping cylinders. At the same time, it is ensured that the trimming system 3 is linked with the shaping cylinders, and the sensor system 33 monitors the cylinder extension length in real time and feeds back the data.

[0031] In this embodiment, the skip shape adjustment system 3 precisely adjusts the shape of the skip; the control system 1 sends a hydraulic cylinder action signal, and the pistons of the shaping hydraulic cylinders on both sides of the skip extend. The sensor system 33 detects the contact between the piston and the skip body and detects the piston extension to form feedback, so as to control the hydraulic cylinder to adjust the skip beyond the limit.

[0032] Furthermore, contact sensor 331 can determine whether the cylinder piston is in contact with the skip body, displacement sensor 332 measures the extension length of the cylinder piston rod, and contour dimension sensor 333 detects the contour dimension of the skip. All sensors are connected to the computer of control system 1 through signal lines to ensure that the data detected by the sensors can be fed back to the computer in real time.

[0033] When the control system 1 sends a shaping signal, the skip shape trimming system 3 activates, the piston extends from the cylinder, and the sensor system set in the trimming system 3 monitors and provides feedback, feeding back the real-time monitoring data to the control system. The displacement sensor 332 detects and feeds back the piston extension, and the contact sensor 331 at the piston head detects whether the piston rod is in contact with the skip body. After the contact sensor 331 at the piston rod head detects that the cylinder is in contact with the skip body, it feeds back to the control system 1. The control system 1 confirms the real-time movement shape of the skip and controls the extension of the cylinder piston. The sensor that detects the skip outline dimensions further confirms the shape and dimensions of the skip, so as to achieve precise real-time trimming of the skip shape.

[0034] Furthermore, as a preferred embodiment, it also includes an early warning system, which is connected to the early warning module of the identification system for receiving and processing data and issuing system early warnings.

[0035] The early warning system is controlled by the control system and is used to issue warnings for abnormal loop formations. When the early warning system detects an abnormal loop formation, the control system issues a warning immediately.

[0036] Example 2 Furthermore, this invention provides an intelligent safety repair method for the skip drum side of an extra-large mine, which is carried out through the aforementioned intelligent safety repair system to achieve skip shape adjustment and improve the safety of the mine hoisting system.

[0037] Specifically, the method includes: When the camera and sensor system 33 of the recognition system 2 detects that the shape and size of the basket have changed to a predetermined value, the control system 1 sends an early warning signal to the staff. After the staff checks the information on the shape and size of the basket collected by the recognition system 2 and the basket shape adjustment system 3, they go to the site to confirm the specific situation of the basket. After confirming that the shape and size of the basket exceeds the limit, the shape of the basket is adjusted. The adjustment mode includes automatic adjustment mode and manual intervention mode.

[0038] The automatic trimming mode includes: the control system 1 intelligently controls the hydraulic cylinder of the skip to move based on the shape information of the skip collected by the camera of the recognition system and the sensor system 33 of the trimming system, the piston of the cylinder extends, and the shape of the skip is trimmed by the piston of the cylinder. The manual intervention mode includes: the operator manually controls the skip shape adjustment system and manually controls the hydraulic cylinder to adjust the skip shape.

[0039] Select the adjustment mode to implement safety protection measures, which include overload protection and fault self-diagnosis function.

[0040] Furthermore, as a preferred embodiment, by integrating the above systems, the intelligent safety repair system is linked with the mine management system to achieve intelligent and safe management of the mine hoisting system; the method includes: The system achieves dual detection through the identification system 2 and the sensor system 33, identifies when the shape and size of the basket exceed the limit, assesses the margin that has reached the dangerous size, and the control system 1 issues an early warning to the staff. After reviewing the measurement data from the identification system 2 and the sensor system 33, staff conducted on-site verification to ensure the condition of the skip deformation. Then, depending on the actual situation, choose between automatic trimming mode or manual intervention mode to trim the winches; Finally, the mine management system records, monitors, or reviews all aspects in real time, forming a closed-loop management system.

[0041] The aforementioned system and methods enable real-time, precise, and dual monitoring of skip morphology, ensuring the safe and stable operation of the mine hoisting system, preventing the danger of skip deformation and collisions with related facilities, and achieving intelligent and efficient mine management. This not only improves the safety of large skips and extends their service life but also provides a guarantee for the construction and operation of ultra-large smart mines.

[0042] The intelligent restoration process for the loop shape in this embodiment is as follows: First, the system monitors and identifies the shape of the loops: After the system is started, the camera of the identification system captures images of the loop shape in real time and transmits the image data to the computer. The computer uses a deep learning algorithm to compare and analyze the real-time collected images of the loop shape with a pre-established normal loop shape model. At the same time, the contour size sensor of the sensor system detects the contour size of the loop in real time and transmits the data to the computer. When the real-time image does not match the normal shape model, or when the contour size sensor detects that the size of the loop exceeds the preset normal range, it is determined that there is an abnormality of the loop bulging.

[0043] Then, the system triggers and transmits warnings: once the system determines that there is an abnormality in the skip, the warning information output module of the skip morphology monitoring and warning system immediately issues a warning signal to remind the monitoring personnel; at the same time, the abnormal data recording module automatically records the time of the abnormality, the location of the skip, the degree of abnormality, and other information; the real-time data transmission module synchronously transmits the abnormal images and sensor detection data to the ground monitoring center for remote viewing by the monitoring personnel.

[0044] Finally, the shape of the loop is refined: Automatic trimming mode: After receiving an early warning signal, monitoring personnel can check abnormal data and images. If the skip's bulging is abnormal and no manual intervention is required, the automatic trimming mode can be activated via computer. The computer calculates the required extension length and force of the hydraulic cylinder based on the image data collected by the recognition system and the contact, displacement, and contour dimension signals fed back by the sensor system. Then, it sends a control signal to the hydraulic system. The hydraulic system drives the shaping cylinder piston to extend. The displacement sensor monitors the cylinder extension length in real time and feeds it back to the computer. When the contact sensor detects that the piston is in contact with the skip body, the computer adjusts the cylinder extension speed and force based on the feedback data. During the trimming process, the contour dimension sensor continuously monitors the skip's contour dimension. When the skip's shape is detected to have returned to the normal range, the computer sends a signal to control the cylinder piston to retract, completing the automatic trimming.

[0045] Manual Intervention Mode: When the skip's shape becomes abnormally complex, or when monitoring personnel determine that manual intervention is necessary, the manual intervention mode can be activated. Operators can manually control the hydraulic control system via the on-site control system's control panel, thereby controlling the extension and retraction of the shaping cylinder. During manual operation, operators can refer to the skip shape image transmitted to the on-site display screen by the high-definition recognition system, as well as the data fed back by the physical sensor system, to adjust the cylinder extension length and force until the skip's shape returns to normal. After the adjustment is completed, operators manually control the cylinder piston to retract.

[0046] During system operation, safety protection measures remain in effect. When the hydraulic system pressure exceeds the preset safety value, the overload protection function is activated, automatically cutting off the power supply to the hydraulic system to prevent the cylinder from being overloaded and damaging the skip or itself. At the same time, the system has a fault self-diagnosis function, which regularly performs self-checks on the hardware equipment (such as cameras, sensors, cylinders, and computers) and software programs of each system. When a fault is detected in the equipment or an abnormality in the program, a fault alarm signal is immediately issued, and the fault location and cause are displayed, which facilitates timely repair by maintenance personnel.

[0047] This invention addresses the technical problems of existing skip repair technologies, such as reliance on manual labor, low safety, poor repair results, and low efficiency. It provides an intelligent and safe skip repair system and method for extra-large mines. The intelligent morphological recognition and precise reset control system for large-tonnage skips offers advantages in safety, efficiency, and intelligence. It enables intelligent identification, precise early warning, automatic or manual repair of skip bulges, and improves mine management, ensuring the safe and stable operation of the mine hoisting system and reducing operating costs. Equipment-based control eliminates the need for manual skip repair, preventing personnel from entering hazardous areas. The repair method offers both automatic and manual modes, using data from camera recognition and relevant sensors to precisely repair the skip's morphology, achieving high efficiency and intelligence. Real-time adjustment of the skip extends its service life, saving time and economic losses associated with manual maintenance and significantly reducing losses due to skip replacement downtime.

[0048] The intelligent safety repair system for extra-large mine skip bulges provided by this invention offers high safety. This system eliminates the need for manual entry into the skip for repair work, fundamentally eliminating safety risks such as falls from heights, material impact injuries, and accidental gate opening faced by workers entering hazardous areas, thus ensuring the personal safety of personnel. Furthermore, the system collects skip morphology image data through an identification system and combines this with a sensor system within the repair system to achieve dual data monitoring, accurately acquiring skip morphology information. The control system intelligently controls the skip morphology repair system based on this data, achieving precise repair of the skip bulges. After repair, the skip maintains a high degree of consistency with the original structure, effectively avoiding the local twisting and deformation problems caused by traditional manual repairs, significantly improving the repair effect. The system has both automatic and manual repair modes. In automatic repair mode, it can complete the identification, early warning, and repair of skip bulges without manual intervention, greatly shortening the repair time. Simultaneously, the system can transmit, process, and record skip morphology data in real time, providing accurate data support for mine management, realizing intelligent management of the mine hoisting system, and improving management efficiency. This invention, through precise and effective maintenance, can prevent skips from aging prematurely due to bulging issues, significantly extending their service life. At the same time, it reduces mine downtime caused by excessive manual maintenance and frequent skip replacements, saving mine operating costs and providing strong support for the long-term stable operation of extra-large smart mines.
