Description

Technical Field

[0001] The invention relates to the technical field of coal mine material transportation, and in particular to a coal mine belt conveyor device and a conveying training system. Background Art

[0002] In coal mining operations, belt conveyors, as key material transportation equipment, are responsible for efficiently and continuously transporting coal from the mining face to the ground or designated processing points. However, in actual operation, belt conveyors face a variety of complex and changing fault challenges, such as failure of roller anti-slip components, malfunction or failure of coal pile protection components, etc. For the above faults, experienced technicians are often relied upon for on-site diagnosis and repair, which is not only time-consuming and labor-intensive, but may not respond quickly in an emergency, resulting in an expansion of the impact of the fault. Especially for newly employed coal miners, due to the lack of necessary fault diagnosis and handling knowledge, they are often at a loss when faced with sudden equipment failures. They can neither effectively determine the cause of the failure nor take correct countermeasures, which not only affects production progress, but also increases the risk of safety accidents. Summary of the invention

[0003] The present invention is based on the inventor's discovery and understanding of the following facts and problems:

[0004] In actual operation, the key equipment of the coal mine belt conveyor is indeed faced with a variety of complex, changeable and unpredictable fault challenges. These faults are not only of various types, but also often sudden and hidden, which brings great trouble to the normal production of coal mines. For example, the failure of the anti-skid component of the roller is a common problem. As an important supporting component of the belt conveyor, once the anti-skid component of the roller fails, it will cause the belt to slip during the conveying process, which will not only seriously affect the conveying efficiency, but also may cause the belt to wear more severely, and even cause more serious equipment failures.

[0005] In addition, the misoperation or failure of the coal pile protection component is also a problem that cannot be ignored in the operation of the coal mine belt conveyor. The main function of the coal pile protection component is to issue an alarm in time and stop the conveyor operation when the coal pile is too high to prevent the collapse of the coal pile and cause casualties and equipment damage. However, due to complex environment, aging of sensors or improper settings, the coal pile protection component sometimes malfunctions, causing the conveyor to suddenly stop during normal operation, affecting production progress; sometimes it completely fails and cannot play the protective role it should, thereby increasing the risk of safety accidents.

[0006] In the face of these failures, the traditional solution often relies on experienced technicians to perform on-site diagnosis and repair. However, this method is not only time-consuming and labor-intensive, but may not respond quickly in an emergency, causing the impact of the failure to expand further. Especially in an environment such as coal mines that have extremely high requirements for production efficiency and safety, any delay may bring immeasurable losses.

[0007] Especially for newly employed coal miners, due to the lack of necessary fault diagnosis and handling knowledge, they are often at a loss when faced with sudden equipment failures. They can neither effectively determine the cause of the failure nor take correct countermeasures. They can only watch the failure affect production progress and even increase the risk of safety accidents. This not only affects the normal production order of the coal mine, but also poses a serious threat to the lives of workers.

[0008] To this end, an embodiment of the present invention proposes a coal mine belt conveyor device, which includes a frame and multiple groups of monitoring components.

[0024] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a coal mine belt conveyor device 100, which includes a frame 10 and multiple groups of monitoring components 20. The frame 10 is provided with multiple safety protection components, and the safety protection component is at least one of an anti-slip component for the belt 12, an iron removal protection component, an anti-deviation protection component and a coal pile protection component; the monitoring component 20 is arranged in a one-to-one correspondence with the safety protection component, and the monitoring component 20 is arranged on the frame 10. The monitoring component 20 includes a camera 21 and a display 22. The camera 21 is used to collect the running image of the safety protection component. The display 22 is electrically connected to the camera 21, and the display 22 is used to display the image collected by the camera 21 and the corresponding operation guide of the safety protection component.

[0026] Specifically, the monitoring component 20 is set in a one-to-one correspondence with the safety protection component. The camera 21 can capture and clearly record the operating status of the safety protection component and the changes in the surrounding environment in real time, ensuring that every key detail is monitored without omission. The display 22 closely connected to the camera 21 instantly displays the dynamic image captured by the camera 21, and on this basis, through the built-in intelligent recognition system or preset program, automatically matches and displays the operation guide or maintenance suggestions of the corresponding safety protection component, so that the operator can quickly identify the problem and take corresponding measures according to the intuitive operation guide. Whether it is daily inspection, troubleshooting or preventive maintenance, it can significantly improve work efficiency and accuracy. At the same time, for new employees, these detailed operation guides are even more valuable learning resources, which help them quickly master equipment operation and maintenance skills and shorten the adaptation period.

[0027] Among them, the anti-slip component of the belt 12 is used to monitor and adjust the tension of the belt 12 or use special materials to enhance friction, effectively preventing material accumulation or transportation interruption caused by slipping of the belt 12; the iron removal protection component is used to use strong magnetic components to timely absorb and remove iron impurities mixed in the material, avoiding potential damage to the conveying equipment and subsequent production processes; the anti-deviation protection component is used to ensure that the belt 12 always maintains the correct route during the conveying process through precise detection and adjustment mechanisms, reducing wear and failure caused by deviation; the coal pile protection component is used to sense the height of the coal pile. Once it exceeds the safety threshold, it will immediately trigger an alarm and take measures to prevent safety accidents such as coal pile collapse.

[0028] In summary, the coal mine belt conveyor device 100 provided in the embodiment of the present invention, by integrating advanced monitoring technology and a comprehensive safety protection mechanism, not only realizes efficient monitoring and intelligent protection of the conveying process, but also effectively promotes the convenience and professionalism of operation and maintenance work, and provides strong support for safe production and efficient operation of the coal mine industry.

[0029] In some embodiments, the monitoring component 20 includes a voice player, which is electrically connected to the display 22, and is used to play the operation guide corresponding to the security protection component displayed on the display screen. The operation guide at least includes the function introduction and operation and maintenance steps of the security protection component.

[0030] Specifically, the voice player can instantly and accurately convert the operating instructions for the safety protection components displayed on the display 22 into voice information, and play it out clearly and smoothly, thereby facilitating the preferences and needs of different operators, and allowing them to receive detailed operating instructions through hearing when it is difficult to see the display 22, thereby completing maintenance and troubleshooting work more efficiently and safely.

[0031] The content of the operation guide can cover multiple aspects such as the functional introduction of the security protection components and the operation and maintenance steps. The functional introduction part can include an in-depth and easy-to-understand explanation of the working principle, scope of action, importance, and common problems that may be encountered for each security protection component, helping operators to quickly establish a comprehensive understanding of the overall architecture and operation mechanism of the equipment. The operation and maintenance steps list in detail the specific operation process of each step from daily inspections, troubleshooting to regular maintenance, including the required tools, precautions, expected results, and possible alternatives, etc., to ensure that operators can strictly follow the specifications and effectively avoid safety hazards caused by misoperation or missing steps.

[0032] For example, for the anti-slip component of the tape 12, the operating guide will introduce in detail how to effectively prevent the tape 12 from slipping by intelligently monitoring and adjusting the tension of the tape 12 or using special materials to enhance friction. At the same time, it will also list daily maintenance steps such as checking the tension of the tape 12, cleaning the anti-slip material, replacing worn parts, and emergency handling procedures when encountering slipping failures. This design allows operators to not only understand the working principle and importance of the safety protection component more clearly, but also be more handy in actual operation to ensure stable operation and safe production of the equipment. In this embodiment, the voice player and the display 22 are integrated into one.

[0033] In some embodiments, the monitoring component 20 includes a bracket 23, the bracket 23 includes an adjustable support rod 231 and a display support 232 connected to each other, one end of the adjustable support rod 231 is connected to the frame 10, and the other end of the adjustable support rod 231 is connected to the display support 232, and the display 22 is arranged on the display support 232, so as to ensure that the display 22 is firmly fixed in the required position, so that the operator can easily observe the operating status of the coal mine belt conveyor 100 and the real-time information of the safety protection component. This design not only improves work efficiency, but also ensures that the operator can promptly discover and deal with potential safety hazards, providing a strong guarantee for the safe production of coal mines.

[0034] Specifically, one end of the adjustable support rod 231 is connected to the frame 10 of the coal mine belt conveyor 100, and the other end of the adjustable support rod 231 is closely connected to the display support 232, which not only ensures that the display 22 can be firmly installed in the desired position, but also gives the display 22 extremely high adjustment flexibility. It can be imagined that the adjustable support rod 231 can allow the operator to easily adjust its length or tilt angle according to actual needs to adapt to different working environments and installation conditions. This design not only improves the installation efficiency, but also ensures that the display 22 can always be kept within the optimal viewing angle range, providing the operator with a clear and comfortable visual experience.

[0035] Furthermore, the frame 10 is provided with a fixed seat 11 and a stop rod 112, the fixed seat 11 is provided with a spherical groove 111, the adjustable support rod 231 has a movable ball head 2311, the movable ball head 2311 is rotatably arranged in the spherical groove 111, and the stop rod 112 is connected between the movable ball head 2311 and the fixed seat 11, so that the display 22 can be easily adjusted in multiple directions. After the display 22 is adjusted to the desired position, the stop rod 112 is tightened to lock its position, thereby ensuring the stability and reliability of the display 22 during operation.

[0036] Furthermore, the fixing seat 11 is provided with a threaded hole 113, and the stop rod 112 is connected to the threaded hole 113 by threading. The stop rod 112 has an abutting end 1121, and the abutting end 1121 is used to abut the movable ball head 2311. Among them, one end of the stop rod 112 can be set as a threaded section, which matches the threaded hole 113 on the fixing seat 11. In other words, by rotating the stop rod 112, it can be easily moved forward and backward in the threaded hole 113, thereby achieving the compression or release of the movable ball head 2311. It is not only simple and easy to use, but also has a very high connection strength, ensuring the stability and safety of the display 22 after adjustment.

[0037] The other end of the stop rod 112 is provided with an abutment end 1121, which can fit tightly on the surface of the movable ball head 2311, thereby achieving effective abutment and locking of the movable ball head 2311, which can improve the locking effect of the stop rod 112 and ensure the stability and smoothness of the display 22 during the adjustment process.

[0038] In actual operation, after the operator adjusts the display 22 to the desired position, the operator only needs to gently rotate the stop rod 112 so that the abutting end 1121 fits tightly against the movable ball head 2311, and the display 22 can be easily locked. When the display 22 needs to be adjusted again, the operator only needs to rotate the stop rod 112 in the opposite direction so that the stop rod 112 is withdrawn from the threaded hole 113, and the locking of the movable ball head 2311 can be easily released, so that the display 22 can be adjusted again.

[0039] In some embodiments, the adjustable support rod 231 includes an inner rod 234, an outer rod 233 and a positioning member 235. The outer rod 233 is provided with a slide groove 2331, and the inner rod 234 is movably arranged in the slide groove 2331. The outer rod 233 is provided with a plurality of fixing holes 2332 at intervals, and the inner rod 234 is provided with a positioning hole 2341. The positioning member 235 is arranged in the positioning hole 2341 and the corresponding fixing hole 2332. Among them, a slide groove 2331 is provided inside the outer rod 233. The inner rod 234 is movably arranged in the slide groove 2331 of the outer rod 233, and the length of the adjustable support rod 231 is flexibly adjusted by telescopic movement inside the outer rod 233. In this embodiment, the number of the fixing holes 2332 is set to 4.

[0040] The positioning member 235 can ensure that the adjustable support rod 231 is firmly locked after being adjusted to the desired length, thereby preventing it from accidentally moving during operation. That is, the positioning member 235 can be easily inserted into the positioning hole 2341 on the inner rod 234 and the corresponding fixing hole 2332 on the outer rod 233, thereby firmly locking the adjustable support rod 231. The fixing holes 2332 are arranged at intervals on the outer rod 233, providing a plurality of optional locking positions for the positioning member 235, thereby meeting different working environments and adjustment requirements.

[0041] In actual operation, the operator only needs to gently move the inner rod 234 to flexibly adjust the length of the adjustable support rod 231. After adjusting to the desired length, the positioning member 235 is inserted into the corresponding positioning hole 2341 and the fixing hole 2332, and the adjustable support rod 231 can be easily locked firmly. This design is not only simple and easy to use, but also greatly improves the adjustment flexibility and stability of the adjustable support rod 231. In this embodiment, the positioning hole 2341 is set as a bolt or a positioning pin.

[0042] In some embodiments, a tape 12 and multiple rollers 13 are provided on the frame 10, and the tape 12 is wrapped around the rollers 13; the anti-bias protection component includes a limiting guide rod, which is rotatably provided on the frame 10, and the limiting guide rod is provided on the outer side of the roller 13, and the distance from the limiting guide rod to the outer edge of the roller 13 is 50 mm to 100 mm.

[0043] Specifically, the belt 12, as the core component of the coal mine belt conveyor 100, is responsible for conveying materials from one end to the other end. The rollers 13 are key components that support the belt 12 and guide it to run smoothly. Multiple rollers 13 are evenly distributed along the length direction of the frame 10, and they together constitute the support system of the coal mine belt conveyor 100. The belt 12 is wound around these rollers 13 to form a continuous and stable conveying channel.

[0044] The limiting guide rod in the anti-deviation protection assembly is rotatably arranged on the frame 10 and is located on the outside of the roller 13, so that it can play a guiding and limiting role during the operation of the belt 12, and prevent the belt 12 from deflecting or falling off due to uneven force or improper operation. And the optimal distance from the limiting guide rod to the outer edge of the roller 13 is 50mm to 100mm, such as 50mm, 60mm, 80mm, 100mm, etc. This distance range not only ensures that the limiting guide rod can effectively play a guiding and limiting role, but also avoids the problem of wear or jamming of the belt 12 caused by too close a distance. At the same time, this design also fully considers the adaptability of the coal mine belt conveyor 100 under different working environments and conditions, ensuring its stability and reliability under various complex working conditions.

[0045] Furthermore, the frame 10 has a head 14 and a tail, and the anti-deviation protection components are provided in two groups, and the two groups of anti-deviation protection components are respectively provided at the head 14 and the tail of the frame 10, thereby ensuring the stability and safety of the tape 12 during the conveying process, and effectively preventing equipment failure and material loss caused by the deviation or falling off of the tape 12.

[0046] In some embodiments, multiple frames 10 are provided, and the coal pile protection assembly is disposed at the overlap of two adjacent frames 10. The coal pile protection assembly includes a coal pile sensor. The coal pile sensor is disposed below the machine head 14 tape 12, and the distance between the coal pile sensor and the machine head 14 tape 12 is greater than or equal to 200 mm. This not only ensures that the coal pile sensor can fully sense the material accumulation situation, but also avoids the problem of false alarm or missed alarm caused by too close distance.

[0047] In some embodiments, the coal pile protection assembly is installed at the top of the coal bunker or at the joint of two belt conveyors. The installation height of the coal pile sensor should be below the level of 200mm below the lower belt of the head 14, and its plane position should be within the range of the coal bunker opening. The installation height of the coal pile sensor is set below the level of 200mm below the lower belt of the head 14, which not only ensures that the coal pile sensor can contact the accumulated coal, but also avoids false alarms caused by vibration or friction caused by the operation of the belt 12.

[0048] In addition, the plane position of the coal pile sensor is set within the range of the coal bunker opening, thereby ensuring that it can fully cover the key area of ​​the coal bunker opening or the overlap of two belt conveyors. This not only improves the sensitivity and accuracy of the coal pile protection component, but also effectively reduces equipment damage and safety hazards caused by coal accumulation.

[0049] In some embodiments, for the scenario where two adjacent frames 10 are vertically overlapped, the coal pile sensor is arranged below the horizontal axis of the roller 13 of the head 14 of the rear conveying device, and its plane position should be in the coal flow direction of the front conveying device, and the lateral distance from the frame 10 of the front conveying device is 200mm to 300mm.

[0050] That is to say, in this vertical overlap scenario, the installation position of the coal pile sensor is carefully set below the axis level of the rear conveyor head 14 roller 13, which can ensure that the coal pile sensor can accurately sense the accumulation of coal at the vertical overlap while avoiding interference from the normal operation of the roller 13 and belt 12. By placing the coal pile sensor below the axis level of the roller 13, we can ensure that it can contact the accumulated coal and sound an alarm when necessary, thereby effectively preventing equipment failures and safety hazards caused by coal accumulation.

[0051] In addition, the plane position of the coal pile sensor was also carefully planned. In order to ensure that it can fully cover the key area of ​​the vertical overlap, we set the plane position of the coal pile sensor in the direction of the coal flow of the front conveyor. This layout not only improves the sensitivity and accuracy of the coal pile protection component, but also ensures that it can monitor the dynamic changes of coal during transportation in real time.

[0052] At the same time, the lateral distance between the coal pile sensor and the front conveying device frame 10 is between 200mm and 300mm, which ensures that the coal pile sensor can fully sense the coal accumulation situation and avoids false alarms or equipment damage caused by too close distance.

[0053] In some embodiments, for the scenario where two adjacent frames 10 are overlapped in parallel, the height of the coal pile sensor should be lower than the horizontal level of the axis of the head 14 roller 13 of the rear conveying device, and the distance from the center of the front conveying device to the farthest coal dropping point is 300mm to 400mm.

[0054] That is to say, in this parallel overlap scenario, the installation height of the coal pile sensor is precisely set below the axis level of the head 14 roller 13 of the rear conveyor device, which can ensure that the coal pile sensor can accurately sense the accumulation of coal at the parallel overlap, while avoiding interference from the roller 13 and belt 12 in normal operation. By placing the coal pile sensor below the axis level of the roller 13, we can ensure that it can contact the accumulated coal and issue an alarm when necessary, thereby effectively preventing equipment failures and safety hazards caused by coal accumulation.

[0055] In addition, the distance from the center of the front conveying device to the farthest coal dropping point is between 300mm and 400mm, which not only ensures that the coal can be smoothly transferred from the front conveying device to the rear conveying device, but also avoids the problem of coal scattering or accumulation caused by excessive distance.

[0056] In addition, an embodiment of the present invention further provides a coal mine transportation training system, which includes the coal mine belt conveyor device 100 provided in the above embodiment. It should be noted that the coal mine transportation training system integrates the coal mine belt conveyor device 100 in the above embodiment to provide a comprehensive, real and safe learning and practice platform for new coal miners.
