Description

Technical Field

[0001] The present invention relates to the field of mine material transportation, and in particular to a mine material transportation belt conveyor and an inspection system thereof. Background Art

[0002] As a key equipment for material transportation, belt conveyors play an irreplaceable role in industrial production. However, in actual operation, belt conveyors have a series of shortcomings and potential safety hazards, which directly affect the operating efficiency and safety of belt conveyors and bring considerable challenges to the production and operation of enterprises.

[0003] The existing mine material conveyor belts have some shortcomings in use and still need to be improved. In the existing technology, first of all, longitudinal tearing of the belt is a serious problem. Since the materials may contain sharp objects or ores, these objects are easy to scratch the belt at the drop point of the belt conveyor, causing longitudinal tearing of the belt conveyor. Once the tearing is found and not handled in time, it will cause long-distance damage to the conveyor belt, causing huge economic losses to the enterprise and even affecting the normal operation of the entire production line.

[0004] Secondly, during the belt transportation process, the belt is easy to deviate from the original running track due to uneven force on the rollers, skewed loading of materials or damage to the rollers. This will not only affect the transportation efficiency of the belt conveyor, but may also cause the belt to detach from the bracket and cause safety accidents.

[0005] In addition, belt slippage and overheating is also a potential safety hazard. During the operation of the belt, due to certain reasons, such as the reduction of the friction coefficient between the belt and the transmission roller, insufficient driving force of the transmission roller, relative movement may occur between the belt and the transmission roller, resulting in slippage and friction. This will not only increase the wear of the transmission roller and the belt, but also increase the temperature to the ignition point, causing a fire accident.

[0006] During the operation of the belt conveyor, due to bearing damage or poor lubrication, the roller is prone to jamming, resulting in increased temperature at the roller shaft or abnormal noise. After long-term operation, the roller will eventually be damaged, affecting the normal operation of the belt conveyor.

[0007] In addition, during the material transportation process, due to the mismatch between the belt conveyor loading volume and the conveying volume or the mismatch between the unloading volume and the downstream usage, it is easy to cause material accumulation at the loading and unloading points. In severe cases, the material may even bury the belt conveyor, causing equipment damage and safety accidents.

[0008] Finally, the abnormal detection of the operating environment around the belt is also a shortcoming in the existing technology. Although a certain safety area is demarcated around the belt conveyor equipment, it is still possible that people enter illegally or other objects intrude during the actual operation. Due to the lack of effective detection methods, these abnormal situations are difficult to detect and handle in a timely manner, thereby increasing the risk of safety accidents. Therefore, we make improvements to this and propose a mine material transportation belt conveyor and its inspection system. Summary of the invention

[0048] How to implement the inspection system The inspection system includes an image acquisition module, an anomaly detection module, an alarm module, a positioning module, a data interaction module and a visualization module.

[0049] The image acquisition module is composed of a patrol visual sensor 12 and a surrounding thermal imaging sensor 13, which are respectively installed on both sides of the conveyor belt 5 and a thermal imaging sensor fixing frame 131, and are used to collect real-time images and temperature information of the belt conveyor.

[0050] The abnormality detection module receives data from the image acquisition module and identifies and judges abnormal conditions of the conveyor belt 5, such as longitudinal tearing, deviation, slipping and overheating, roller damage, and material piling. The calculation formula for the belt overtemperature alarm threshold is: T_{alarm}=T_{max}+ΔT, where T_{alarm} is the alarm threshold, T_{max} is the maximum allowable operating temperature of the belt, and ΔT is the temperature safety margin.

[0051] When an abnormal situation is detected, the alarm module sends out an alarm signal in the form of sound, light or electrical signal. The positioning module determines the specific location according to the abnormal situation and provides a basis for processing.

[0052] The data interaction module interacts with other systems to achieve real-time data transmission and the establishment of interactive channels. The visualization module transmits real-time images or other equipment signals on site to the equipment operation control room for secondary review by the operator.

[0053] The precise coordination of the driving motor 2, the coupling 3 and the driving roller 4 ensures that the belt conveyor has a stable running speed and reliable power transmission during the material transportation process, effectively improving the transportation efficiency. At the same time, the setting of the belt roller 6, the anti-slip roller 7 and the tensioning roller 8 enhances the stability of the belt during transportation, reduces the possibility of belt deviation and slippage, and further improves the overall transportation stability.

[0054] The anti-skid convex pattern 701 provided on the anti-skid roller 7 effectively increases the friction between the belt and the roller, prevents the belt from slipping during transportation, and reduces the failure rate. In addition, the application of the inspection visual sensor 12 and the surrounding thermal imaging sensor 13 makes it possible to monitor and warn the operation status of the belt conveyor in real time, detect potential failures in time, and reduce maintenance costs.

[0055] The track wheel 11 set at the bottom of the belt conveyor allows the entire device to move freely on the track, which is convenient for material transportation at different work locations. At the same time, the abnormality detection module in the inspection system can monitor the abnormality of the belt in real time, and send out an alarm signal in time through the alarm module, thereby improving the safety of the belt conveyor. In addition, the application of the positioning module can quickly locate the location where the abnormality occurs, which provides convenience for timely handling of faults.

[0056] The visualization module in the inspection system transmits the real-time images of the scene back to the equipment operation control room, so that the operator can intuitively understand the operation status of the belt conveyor, improving the convenience of human-computer interaction. At the same time, the data interaction module interacts with the data of other systems, so that the operation data of the belt conveyor can be shared in real time, providing strong support for management decisions.

[0057] The inspection system realizes intelligent monitoring and management of the belt conveyor's operating status through the coordinated work of multiple modules including image acquisition module, abnormality detection module, alarm module, positioning module and data interaction module. In addition, through the application of belt deviation calculation formula and belt over-temperature alarm threshold formula, the abnormal situation of the belt conveyor is judged more accurately, and the degree of automation is improved.

[0058] The alarm module belt over-temperature alarm threshold formula: T alarm =T max +ΔT; where: T alarm : Belt over-temperature alarm threshold; T max : The maximum operating temperature allowed for the belt, which is the maximum temperature the belt can reach under normal operating conditions. Exceeding this temperature may cause belt damage or performance degradation; ΔT: Temperature safety margin, which is an additional temperature value added to the maximum operating temperature to ensure that an alarm is issued before a temperature that may damage the belt is reached.

[0059] Pile detection threshold formula: H alarm =H max +ΔH; H alarm : Pile detection alarm threshold; H max : The maximum material stacking height allowed by the belt conveyor; ΔH: height safety margin; Explanation: This formula is used to set the alarm threshold for pile detection. During the operation of the belt conveyor, if the material pile exceeds the maximum allowable height, it may cause equipment failure or safety accidents. Therefore, by subtracting a height safety margin from the maximum allowable pile height, the threshold for pile detection alarm is obtained. When it is detected that the material pile exceeds this threshold, the system will issue a pile alarm signal.

[0060] The magnetic tensioning mechanism 16 can automatically adjust the tension of the conveyor belt to ensure that the belt remains in an appropriate tight state during transportation, reduce belt slippage or excessive wear, and thus improve the efficiency and stability of material transportation.

[0061] The design of the tape strip 14 and the tape buckle 1401 makes the installation, removal and replacement of the conveyor belt simple and quick, reducing maintenance costs and time. At the same time, the design of the cross pin 1402 enhances the stability of the connection and reduces the downtime caused by loose connection.

[0062] The combination of permanent magnetic roller 1501 (model: CMYG-N32) and magnetic rotor 1502 (model: CZZ-T200) uses magnetic force to achieve non-contact drive, reducing mechanical friction, noise and vibration, while also avoiding potential safety hazards caused by traditional drive methods, such as material scattering due to belt breakage or slippage.

[0063] Due to the use of permanent magnetic materials and magnetic drive, this design has low energy consumption during operation and does not require frequent replacement of worn parts, reducing resource consumption and waste generation, and meeting the requirements of modern industry for energy conservation and environmental protection.

[0064] Working principle: The working principle of the mine material conveyor belt conveyor is mainly based on magnetic drive and automatic tension adjustment system. The non-contact drive is realized by magnetic force, which reduces mechanical friction, noise and vibration, and also avoids the potential safety hazards caused by traditional drive methods. At the same time, the magnetic ring 1601 (model: CML-E50) in the magnetic tensioning mechanism 16 automatically slides in the magnetic sliding frame 1603 according to the tightness of the belt, and adjusts the tension of the belt through the tensioning rod 1602 to maintain its stable operation.

[0065] Workflow: Check whether all components are installed in place, and confirm that there are no abnormalities in the permanent magnetic roller 1501 (model: CMYG-N32), the magnetic rotor 1502 (model: CZZ-T200) and the magnetic tensioning mechanism 16.

[0066] The magnetic tensioning mechanism 16 automatically works according to the tension of the belt. When the belt is loose, the magnetic ring 1601 (model: CML-E50) slides in the tensioning direction in the magnetic sliding frame 1603, and increases the tension of the belt through the tensioning rod 1602; on the contrary, when the belt is too tight, the magnetic ring 1601 (model: CML-E50) slides in the opposite direction to reduce the tension and ensure that the belt is in the best working state. The permanent magnetic roller 1501 (model: CMYG-N32) reduces the friction of the conveyor belt during transportation.

[0067] Operators need to regularly check the wear of the conveyor belt, the working condition of the tensioning mechanism, and the magnetic strength of the permanent magnetic roller 1501 (model: CMYG-N32) and the magnetic rotor 1502 (model: CZZ-T200) to ensure the safe and reliable operation of the equipment. If any abnormality is found, the equipment should be shut down for inspection and repair in time. When the transportation task is completed, turn off the external power source and stop the equipment. Clean the material residues in the conveyor belt and surrounding areas as needed to prepare for the next use.

[0068] Working principle and workflow of mine material transport belt conveyor: 1. Driving and transmission principle: The driving motor 2 is connected to the driving roller 4 through the coupling 3 to provide power for the belt conveyor. When the driving motor 2 is started, the coupling 3 transmits power to the driving roller 4, causing the driving roller 4 to start rotating.

[0069] The roller shaft 401 is inserted into the roller bearing 402 to ensure the stable rotation of the active roller 4. At the same time, the roller bearing 402 is installed on the roller frame 403 to provide necessary support and positioning.

[0070] The outer surface of the driving roller 4 is wrapped with a conveying belt 5. When the driving roller 4 rotates, the conveying belt 5 moves accordingly to form a channel for material transmission.

[0071] 2. Material transfer process: The material is placed at the starting end of the conveyor belt 5, and as the belt moves, the material is transferred to the other end of the belt conveyor.

[0072] During the transmission process, the belt roller 6 and the anti-skid roller 7 play a role in supporting and preventing the belt from slipping. The anti-skid convex pattern 701 on the anti-skid roller 7 increases the friction between the belt and improves the stability of the transmission.

[0073] The tensioning roller 8 is used to adjust the tension of the belt to ensure that the belt maintains an appropriate tension state during transmission and prevent the belt from loosening or over-stretching.

[0074] The anti-deflection side plates 9 are obliquely arranged on both sides of the conveyor belt 5 to prevent the material from deflecting to one side during the transmission process, thereby ensuring the accuracy and stability of the material transmission.

[0075] At the other end of the belt conveyor, the ice bucket roller 10 is used to assist in unloading the material, ensuring that the material can be unloaded from the belt smoothly.

[0076] Movement and positioning: The four symmetrical track wheels 11 arranged at the bottom of the main frame 1 allow the entire belt conveyor to move freely on the track, facilitating material transportation at different work locations.

[0077] The track wheel 11 is fixed on the wheel frame 111, and the wheel frame 111 is connected to the main frame body 1, thereby ensuring the stability and safety of the entire structure.

[0078] Working principle and workflow of inspection system Image acquisition: The inspection visual sensor 12 and the surrounding thermal imaging sensor 13 are respectively installed on the two sides of the conveyor belt 5 and the thermal imaging sensor fixing frame 131, and are used to collect the image and temperature information of the belt conveyor in real time.

[0079] The inspection visual sensor 12 can capture the status information of the conveyor belt 5, the belt roller 6 and the material, including the wear of the belt, the operating status of the roller and the distribution of the material.

[0080] The surrounding thermal imaging sensor 13 can monitor the temperature distribution of the surrounding environment of the belt conveyor in real time, which helps to detect potential thermal anomalies or equipment overheating.

[0081] Abnormality detection and judgment: The abnormality detection module receives data from the image acquisition module and uses image processing and pattern recognition technology to identify and judge abnormal conditions of the belt conveyor.

[0082] The contents of the inspection include longitudinal tearing, deviation, slippage and overheating of the conveyor belt 5, damage to the rollers, and abnormal stacking.

[0083] By analyzing image information and temperature data, the anomaly detection module can accurately determine the operating status of the belt conveyor and discover potential problems in a timely manner.

[0084] Alarm and positioning: When the abnormality detection module detects an abnormal situation, it will trigger the alarm module to send an alarm signal. The alarm signal can be presented in the form of sound, light or electrical signal to attract the attention of the operator.

[0085] At the same time, the positioning module will locate the location of the anomaly based on the information provided by the anomaly detection module, and provide the operator with accurate fault point information for timely processing.

[0086] Data interaction and visualization: The data interaction module is responsible for data interaction with other systems to achieve data sharing and transmission. This includes the establishment of interaction channels with other monitoring systems, data interface development, and real-time data transmission.

[0087] The visualization module transmits the real-time images or other equipment signals of the site to the equipment operation control room in real time for the operator to review. Through the visualization interface, the operator can intuitively understand the operation status and abnormal conditions of the belt conveyor, which is convenient for remote monitoring and operation.

[0088] Through the description of the working principle and workflow above, it can be seen that this mine material transport belt conveyor and its inspection system can achieve efficient and stable material transmission, and timely discover and deal with potential problems through the intelligent inspection system, thereby improving the safety and efficiency of mine material transportation; The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods.
