Description

Technical Field

[0001] The invention relates to the technical field of underground coal mine transportation, and in particular to an underground coal mine belt conveyor with a roller fault monitoring device. Background Art

[0002] In mountainous or hilly areas, the adit is a common method of ore body development, which is developed directly from the surface to the ore body. During adit development, the main adit is responsible for transportation, air intake, drainage, pipeline laying and other tasks. Return air adit or return air shaft is excavated at the upper boundary to form a ventilation system. According to the terrain and external conditions, the adit can be opened in the roof rock, floor rock or ore body, perpendicular or oblique to the ore body direction, or along the ore body or coal seam direction. In the development of coal seams, when the terrain conditions and the scope of the mine field are suitable, the mining level can be established at the main adit elevation, and adit development can be carried out up and down the mountain. If the vertical height or inclined length of the coal seam above the horizontal level of the horizontal tunnel is too large, a stepped multi-level tunnel development method can be used. In the actual coal mine transportation process, belt conveyors are the main transportation equipment of the raw coal transportation system under the horizontal tunnel development method. With the gradual increase in the mining depth of coal mines and the continuous development of coal mining technology, belt conveyors are also gradually developing towards long transportation distances, large transportation volumes, and high reliability.

[0003] The operating status of the belt conveyor has a significant impact on the safe production of the belt conveyor and the mine. The roller is an important component that determines the use effect of the belt conveyor. Among them, the hidden danger caused by the failure of the roller card group is the most serious. For this reason, in the prior art, each belt conveyor is equipped with a fixed staff to monitor the operating status of the belt conveyor at regular intervals and points. However, the horizontal working environment is harsh and complex, and the staff monitors in shifts day and night, but the monitoring effect is poor and the labor cost is high.

[0004] To this end, we provide underground coal mine belt conveyors with roller fault monitoring devices to solve the above problems. Summary of the invention

[0005] In response to the problems existing in the above-mentioned prior art, the present invention provides a belt conveyor for underground coal mines with a roller fault monitoring device. By integrating the fault monitoring system, real-time monitoring and early warning of roller faults can be achieved, thereby effectively improving the safety and reliability of the equipment, reducing the downtime caused by faults, and improving the transportation efficiency of coal mines.

[0006] In order to achieve the above-mentioned object, the present invention adopts an underground coal mine belt conveyor with a roller fault monitoring device, comprising:

[0007] A belt conveyor body, which is arranged underground in a coal mine. The belt conveyor body is provided with a head and a frame in sequence along the coal transport direction. A driving roller is provided inside the head. The input end of the driving roller is connected to a conveyor motor. A plurality of upper rollers arranged in a straight line are provided above the frame. A plurality of lower rollers are provided below the frame. The driving roller, the upper rollers and the lower rollers are connected by a conveyor belt, and the upper surface of the conveyor belt is a coal transport surface. A fault monitoring system for monitoring the belt conveyor body is provided on the side of the belt conveyor. The driving mechanism provides power for the fixed monitoring system and drives the fault monitoring system to move along the conveying direction of the belt conveyor.

[0008] A fault monitoring system comprises a fixed frame installed on the side of a frame, the fixed frame is provided with two parallel connecting slide rails, the connecting slide rails are provided with a main structure, the upper part of the main structure is a walking structure and the walking structure and the connecting slide rails are a matching structure, and the lower part of the main structure is a monitoring mechanism composed of a sensor, a camera and a controller.

[0009] The above structure integrates a fault monitoring system based on the original mechanism of the belt conveyor, which eliminates the need for real-time monitoring by staff and reduces labor input. At the same time, it realizes real-time monitoring of roller faults, effectively improves the safety and reliability of the equipment, reduces downtime caused by faults, and improves the transportation efficiency of coal mines.

[0010] As a further optimization of the above scheme, the driving mechanism includes a motor, a rotating roller, a guide roller and a wire. There are two rotating rollers and they are respectively installed at the two ends of the connecting slide rail. The rotating roller is installed at the output end of the motor. A wire is wound around the rotating roller. A guide roller is arranged on the moving path of the wire. A guide groove is arranged on the outer surface of the guide roller. The wire passes through the guide groove and is connected to the walking structure. The connecting slide rail has a first supporting part, a vertical part and a second supporting part arranged in sequence from top to bottom. The first supporting part, the vertical part and the second supporting part constitute an I-shaped structure. The walking structure has a first roller in contact with the first supporting part, and a connecting frame is provided on the side of the first roller. Two second rollers in contact with the side of the vertical part are provided on the connecting frame, and the two second rollers are arranged opposite to each other.

[0011] The above structure uses guide rollers to support and guide the wires, ensuring close contact between the wires and the guide grooves, thereby guiding the walking structure to move smoothly along the direction of the rotating rollers to ensure effective displacement of the walking structure. At the same time, the first roller and the second roller provided in the structure are firmly fixed in the vertical and horizontal dimensions respectively, and through synergy, guide the walking structure to slide smoothly along the connecting track. Specifically, the first roller is responsible for limiting the up and down displacement of the walking structure, while the second roller prevents it from shifting left and right. Together, the two ensure the stability of the fault monitoring system during movement.

[0012] As a further optimization of the above scheme, the walking structure also has a connecting shaft passing through the two first rollers, the connecting shaft is passed through a first gear, a driving end of the first gear is connected to a driving component that drives the first gear to rotate, the driving component includes a fixed plate, a second gear, a third gear, a rotating shaft and a driving motor, a fixing plate is provided on the side of the first gear, a second gear meshing with the first gear is installed on the fixing plate, a third gear that is a matching structure with the second gear is provided on the side of the second gear, the third gear is connected to the driving motor through the rotating shaft, and the connecting slide rail has A straight section and an inclined section, the inclined section is provided with an inclined tooth plate, one side of the tooth plate is provided with an inclined portion for the third gear to rise, and the third gear is meshed with the second gear after lifting, the third gear, the rotating shaft and the driving motor are all connected to the mounting plate, the mounting plate is provided with a moving block, the fixed plate is provided with a limiting groove as a matching structure with the moving block, a battery is provided on the top of the walking structure, the mounting plate is provided with a male plug end of the driving motor, the battery is provided with a female plug end as a matching structure with the male plug end, and the female plug end is located on the moving path of the male plug end;

[0013] The above structure incorporates a multiple gear transmission mechanism. When the walking structure moves to the inclined section connected to the slide rail, the preset third gear precisely engages with the toothed plate on the rail. This engagement action causes the third gear, the drive motor and the mounting plate to tilt upward and tightly connect the male plug end with the female plug end, thereby starting the drive motor. The activated drive motor provides itself with rotational power and drives the entire multiple gear transmission mechanism to operate through the linkage effect between the gears. Specifically, the rotation of the third gear not only directly promotes its own movement, but also in this transmission mechanism, the second gear rotates synchronously with the third gear, and the first gear rotates synchronously with the second gear, thereby driving the roller to rotate, significantly enhancing the traction of the walking structure during the climbing process, effectively reducing the tension burden of the wire on the walking structure, reducing the risk of the wire breaking due to excessive stretching during the climbing process, and ensuring the smooth and efficient movement of the walking structure.

[0014] As a further optimization of the above scheme, the walking structure is also provided with a first part and a second part which are arranged relatively to each other in an upper and lower manner, the driving assembly is installed on the second part, and a cross-lifting mechanism is provided on the first part and the second part, and when the walking structure climbs along the inclined section, the cross-lifting mechanism is in a descending state, and the cross-lifting mechanism includes a first sliding plate, the first sliding plate is provided on the first part, both ends of the first sliding plate are connected to wires, both ends of the first sliding plate are hinged with first hinged plates, the other end of the first hinged plate is hinged to the second part, and a second sliding plate is provided on the second part, both ends of the second sliding plate are hinged with second hinged plates, one end of the second hinged plate is hinged to the first part, and the middle part of two adjacent first hinged plates is hinged to the second hinged plate.

[0015] In the above structural design, the walking structure is endowed with two operation modes to cope with different terrain conditions. The first is the climbing mode. In this mode, by stretching the wire on one side, the cross-lifting mechanism is lowered to a low position, ensuring that when the walking structure climbs the slope, the third gear can contact the tooth plate on the inclined section of the track. This contact provides additional assistance for the climbing process through the interaction between the gears, significantly enhancing the climbing ability;

[0016] In addition, the downhill mode is achieved by stretching the wire on the other side to raise the cross-lifting mechanism to a high position. In this state, the third gear remains separated from the inclined section tooth plate to avoid unnecessary mechanical engagement between the third gear and the tooth plate, thereby preventing reverse driving force or friction resistance that may be generated by the contact between the gear and the tooth plate when going downhill, thereby reducing the potential impact of the auxiliary power structure on the walking stability during the downhill process, ensuring the smooth movement of the walking structure in complex terrain, and ensuring the reciprocating monitoring of the belt conveyor by the walking structure.

[0017] The underground coal mine belt conveyor with the roller fault monitoring device of the present invention has the following beneficial effects:

[0018] The underground coal mine belt conveyor with a roller fault monitoring device of the present invention integrates a fault monitoring system on the basis of the original mechanism of the belt conveyor, eliminates the need for real-time monitoring by staff, reduces labor input, and simultaneously realizes real-time monitoring of roller faults, effectively improves the safety and reliability of the equipment, reduces downtime caused by faults, and improves the transportation efficiency of coal mines.

[0019] The underground coal mine belt conveyor with a roller fault monitoring device of the present invention uses guide rollers to support and guide the conductors, ensuring that the conductors are in close contact with the guide grooves, thereby guiding the walking structure to move smoothly along the direction of the rotating rollers to ensure the effective displacement of the walking structure. At the same time, the first roller and the second roller provided in the structure are firmly fixed in the vertical and horizontal dimensions respectively, and through synergy, guide the walking structure to slide smoothly along the connecting track. Specifically, the first roller is responsible for limiting the up and down displacement of the walking structure, while the second roller prevents it from deviating left and right. The two together ensure the stability of the fault monitoring system during movement.

[0020] The underground coal mine belt conveyor with a roller fault monitoring device of the present invention incorporates a multiple gear transmission mechanism. When the walking structure moves to the inclined section connected to the slide rail, the preset third gear accurately meshes with the toothed plate on the rail. The meshing action prompts the third gear, the driving motor and the mounting plate to move tilted upward, and makes the male plug end and the female plug end tightly docked, thereby starting the driving motor. The activated driving motor provides rotational power for itself, and drives the entire multiple gear transmission mechanism to operate through the linkage effect between the gears. Specifically, the rotation of the third gear not only directly promotes its own movement, but also in this transmission mechanism, the second gear rotates synchronously with the third gear, and the first gear rotates synchronously with the second gear, thereby driving the roller to rotate, which significantly enhances the traction force of the walking structure during the climbing process, effectively reduces the tension burden of the wire on the walking structure, reduces the risk of the wire breaking due to excessive stretching during the climbing process, and ensures the smooth and efficient movement of the walking structure.

[0021] The underground coal mine belt conveyor with roller fault monitoring device of the present invention is endowed with two operation modes to cope with different terrain conditions. The first is a climbing mode. In this mode, the cross-lifting mechanism is lowered to a low position by stretching the wire on one side, ensuring that the third gear can contact the tooth plate on the inclined section of the track when the walking structure climbs the slope. The contact provides additional assistance for the climbing process through the interaction between the gears, significantly enhancing the climbing ability.

[0022] In addition, the downhill mode is achieved by stretching the wire on the other side to raise the cross-lifting mechanism to a high position. In this state, the third gear remains separated from the inclined section tooth plate to avoid unnecessary mechanical engagement between the third gear and the tooth plate, thereby preventing reverse driving force or friction resistance that may be generated by the contact between the gear and the tooth plate when going downhill, thereby reducing the potential impact of the auxiliary power structure on the walking stability during the downhill process, ensuring the smooth movement of the walking structure in complex terrain, and ensuring the reciprocating monitoring of the belt conveyor by the walking structure.

The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation method.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs. The terms used in the specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0042] Please refer to the instruction manual Figure 1-4The present invention provides a first embodiment of an underground coal mine belt conveyor with a roller fault monitoring device, including the following structural designs:

[0043] The structure of the belt conveyor body 1 is specially customized for the underground working environment of the coal mine. It is arranged along the transportation path of the coal mine, and is sequentially configured with the core component head 11 and the supporting structure frame 12. The head 11 is integrated with a drive roller 13 as the core of the transmission power. The input end of the drive roller 13 is connected to the conveyor motor 14 to ensure continuous and stable power output. On the frame 12, there are multiple groups of upper rollers 15 and lower rollers 16, which are respectively located on the upper and lower sides of the conveyor belt 17, and are closely arranged in a straight line direction to jointly support and guide the conveyor belt 17 to run smoothly. Among them, the upper rollers 15 and the lower rollers 16, as well as the drive roller 13, are closely connected through the conveyor belt 17 to form a closed-loop transmission system, and the upper surface of the conveyor belt 17 directly carries and transports coal and mineral materials.

[0044] Based on the belt conveyor body 1, this embodiment integrates a fault monitoring system 2. The core component of the fault monitoring system 2 includes a fixed frame 21 installed on the side of the frame 12, and two parallel connecting rails 22 are arranged on the fixed frame 21. The connecting rails 22 are equipped with a main structure 23, and the main structure 23 consists of an upper walking structure 24 and a lower monitoring mechanism 231.

[0045] Specifically, the cause of the failure is generally that during the operation of the conveyor, the kinetic energy and potential energy of the conveyor belt 17 during operation are converted into the kinetic energy of the roller rotation and the heat energy generated by the friction of the contact surface, so that the contact surface friction between the conveyor belt 17 and the roller generates heat and the temperature rises. Once the roller fails, the roller will rotate slowly or get stuck and stop, causing the temperature of the roller to rise sharply, which can easily cause serious fire accidents.

[0046] The walking structure 24 and the connecting slide rail 22 are a matching structure to form a stable mobile platform. The driving mechanism 3 provides power for the walking structure 24, driving the walking structure 24 to shuttle freely on the slide rail to achieve comprehensive monitoring of the belt conveyor. The lower monitoring mechanism 231 integrates core components such as sensors, cameras and controllers to capture and analyze the operating status of key parts of the conveyor in real time. The specific monitoring method of the monitoring mechanism 231 is as follows:

[0047] Please refer to Figure 4The monitoring mechanism 231 includes video monitoring and temperature monitoring, wherein the video monitoring is a real-time monitoring of the running status of the belt conveyor. First, the corresponding image is extracted from the video image, including visible light video image and infrared thermal imaging video image. At the same time, the sensor collects corresponding data information such as temperature, and the controller processes the data information. The image data information and the sensor data information are directly transmitted to the host computer through the wireless communication system. The host computer processing system processes the video image and monitors the running status of the roller, and presents the received data and processed image results to the staff in the form of an artificial interactive interface. The collected data information and video images are the basis for monitoring and judging the working status of the belt conveyor and the monitoring mechanism 231. The host computer can judge whether it meets the standards for safe production operations through the data information. When the monitoring mechanism 231 detects abnormal data information and roller card group failure, the monitoring mechanism 231 automatically issues an alarm or stops walking, and records the time, location and data information at this moment.

[0048] It should be noted that the temperature field distribution of the roller monitored by the monitoring mechanism 231 is as follows: Fig.12 As shown in the figure, the infrared image of the roller in the normal state is as follows: Fig.13 As shown in the figure, the infrared image of the roller in the blocked state is as follows Fig.14 shown.

[0049] Please refer to the instruction manual Figure 1-11 The present invention provides a second embodiment of an underground coal mine belt conveyor with a roller fault monitoring device. Based on the structure of the first embodiment, the driving mechanism 3 is further described. Specifically:

[0050] Please refer to Figure 3-Figure 6 The driving mechanism 3 is mainly composed of a motor 31, two rotating rollers 32, a guide roller 33 and a wire 34. The two rotating rollers 32 are respectively mounted on the two ends of the connecting slide rail 22, and the rotating rollers 32 are connected to the output end of the motor 31. The wire 34 is wound on the wire 34 roller and passes through the guide roller 33 along a preset path, wherein the surface of the guide roller 33 is provided with a guide groove 331, and the wire 34 passes through the guide groove 331 and is connected to the walking structure 24. The connecting slide rail is designed to be an I-shaped, including a first support part 221, a vertical part 222 and a second support part 223. The walking structure 24 is equipped with a first roller 241, which is in contact with the first support part 221; the first roller 241 is arranged on the connecting frame 242 of the walking structure 24, and two second rollers 243 are installed on the connecting frame 242, and the two second rollers 243 are arranged opposite to each other and in contact with the side of the vertical part 222.

[0051] The above design realizes the support and guiding function of the wire 34 through the guide roller 33, ensuring that the wire 34 fits tightly in the guide groove 331, and then guides the walking structure 24 to stably move toward the rotating roller 32 in a single direction, ensuring the effective displacement of the walking structure 24. At the same time, the first roller 241 and the second roller 243 provide stable support in the vertical and horizontal directions respectively, and the two work together to ensure that the walking structure 24 can slide smoothly along the connecting track. Specifically, the first roller 241 is responsible for controlling the vertical displacement of the walking structure 24, while the second roller 243 prevents its horizontal deviation. The two together maintain the stability of the fault monitoring system 2 when it moves.

[0052] See also Figure 4-Figure 8 On the basis of the above scheme, the walking structure 24 is further provided with a connecting shaft 244, which passes through the two first rollers 241 and is equipped with a first gear 245. The driving end of the first gear 245 is connected to a set of driving components 4, and the driving component 4 includes a fixed plate 41, a second gear 42, a third gear 43, a rotating shaft and a driving motor 44. A fixed plate 41 is provided beside the first gear 245, and a second gear 42 meshing with the first gear 245 is installed on the fixed plate 41. A third gear 43 meshing with the second gear 42 after rising is arranged beside the second gear 42. The third gear 43 is connected to the driving motor 44 through a rotating shaft. The connecting slide design includes a straight line The third gear 43 is provided with an inclined section 224 and an inclined section 225, wherein the inclined section 225 is provided with an inclined tooth plate 226, and one side of the tooth plate 226 is provided with an inclined portion 227 for the third gear 43 to climb. When the third gear 43 is lifted along the inclined portion 227, the third gear 43 meshes with the second gear 42. The third gear 43, the rotating shaft and the driving motor 44 are installed on the mounting plate 45. The mounting plate 45 is also provided with a moving block 46, which cooperates with the limiting groove 411 on the fixing plate 41. The top of the walking structure 24 is equipped with a battery 5, and the mounting plate 45 is provided with a male plug end 451 of the driving motor 44. The battery 5 is correspondingly provided with a female plug end 51, and the female plug end 51 is located on the moving track of the male plug end 451.

[0053] It should be noted that Figure 7 for Figure 6 A partial enlarged view of the main view. Figure 8 for Fig. 9 A partial enlarged view of the middle fixed plate part.

[0054] like Fig.10As shown, the above structure incorporates a multiple gear transmission structure. When the walking structure 24 moves to the inclined section 225 connected to the slide rail and climbs the slope, under the action of the inclined portion 227 on the tooth plate 226, the third gear 43 is lifted and meshed with the second gear 42. At the same time, the mounting plate 45 rises accordingly, and the male plug end 451 is connected to the female plug end 51, so that the battery 5 supplies power to the motor 31, and the drive motor 44 provides power for the operation of the entire multiple gear transmission structure. Through the linkage between the gears, the entire multiple gear transmission structure is driven to operate. Specifically, the rotation of the third gear 43 drives itself to move, and drives the second gear 42 to rotate synchronously, thereby driving the first gear 245 and the roller to rotate, significantly enhancing the traction of the walking structure 24 when climbing, effectively reducing the tension burden of the wire 34, and reducing the risk of the wire 34 breaking due to excessive stretching, ensuring the smooth and efficient movement of the walking structure 24.

[0055] It should be noted that the above-mentioned limit groove 411 is an inclined upward structure, so that the above-mentioned third gear 43 moves upwardly at an angle. After disengaging from the tooth plate 226, under the action of gravity, the third gear 43 disengages from the second gear 42 and moves downward, and the male plug end 451 is separated from the female plug end 51.

[0056] In addition, the walking structure 24 can be further optimized by setting a first part 6 and a second part 7 that are opposite to each other in the upper and lower parts. The driving component 4 is installed on the second part 7 so that the above-mentioned driving component 4 can rise and fall with the above-mentioned second part 7. The monitoring mechanism 231 is installed on the lower surface of the above-mentioned first part 6. The first part 6 and the second part 7 are equipped with a cross-lifting mechanism 8. When the walking structure 24 climbs the slope along the inclined section 225, the cross-lifting mechanism 8 is in a low position.

[0057] It should be noted that if Figure 7 As shown, the second gear 42 is located above the first gear 245 , so the lifting and lowering of the second gear 245 will not affect the meshing of the second gear 42 and the first gear 245 .

[0058] More specifically, Fig. 9 As shown, with respect to the cross-lifting mechanism 8, in this embodiment, the cross-lifting mechanism 8 includes a first sliding plate 81, a first hinged plate 82, a second sliding plate 83 and a second hinged plate 84, the first sliding plate is arranged on the first part 6, both ends of the first sliding plate 81 are connected to the wire 34, both ends of the first sliding plate 81 are hinged with the first hinged plate 82, the other end of the first hinged plate 82 is hinged on the second part 7, the second part 7 is provided with a second sliding plate 83, both ends of the second sliding plate 83 are hinged with the second hinged plate 84, one end of the second hinged plate 84 is hinged on the first part 6, and the middle part of the two adjacent first hinged plates 82 and the second hinged plate 84 is hinged.

[0059] It should be noted that a limiting groove or other structure for limiting the moving range of the first sliding plate 81 may be further provided on the first portion 6 to limit the moving range of the first sliding plate 81 .

[0060] like Fig.11 As shown, the above structural design enables the walking structure 24 to have two operation modes to flexibly cope with different terrain conditions. In the climbing mode, by stretching the wire 34 on one side, the cross-lifting mechanism 8 will drop to a low position. In this way, when the walking structure 24 climbs the slope, the third gear 43 can be in close contact with the tooth plate 226 on the inclined section 225 of the track. The interaction between the gears provides additional assistance for the climbing process, significantly enhancing the uphill ability.

[0061] In the downhill mode, the cross-lifting mechanism 8 will rise to a high position by stretching the wire 34 on the other side. At this time, the third gear 43 and the tooth plate 226 of the inclined section 225 remain separated, avoiding unnecessary mechanical engagement. In this way, during the downhill process, the reverse driving force or friction resistance that may be generated by the contact between the gear and the tooth plate 226 can be effectively prevented, thereby reducing the potential impact of the auxiliary power structure on the walking stability. This design ensures the smooth movement of the walking structure 24 in complex terrain and ensures that the walking structure 24 can reciprocate and monitor the belt conveyor.

[0062] Based on the original mechanism of the belt conveyor, the present invention integrates a fault monitoring system 2, which eliminates the need for real-time monitoring by staff and reduces labor input.
