[0031] The present application discloses a mine conveyor belt fault detection device, which is placed under the conveyor belt in the mine for use. A photographing device is used to clearly observe whether the conveyor belt has deviation, tearing, foreign matter, bulging, exposed steel core and other problems, and presents them on a display screen. The setting of the perspective cylinder can isolate the dust in the mine from affecting the photographing device, and the cleaning device is used to continuously clean the outer surface of the perspective cylinder to prevent dust from covering and blocking the photographing device from photographing the conveyor belt.

[0032] Furthermore, as a preferred embodiment of the present invention but not a limitation, the driving device 5 includes a power source 51 and a converter 52 connected to the output end of the power source 51, the first output end 521 of the converter 52 is provided with a first gear 5211, and the perspective cylinder 2 is provided with a second gear 21 meshing with the first gear 5211.

[0033] In this embodiment, a servo motor is used as the power source. The servo motor drives the first gear to rotate, and through meshing with the second gear teeth on the perspective cylinder, the perspective cylinder starts to rotate, so that the cleaning device can effectively clean the outer surface of the perspective cylinder through gear transmission under the drive of the power source.

[0034] Furthermore, as a preferred embodiment of the present invention but not a limitation, the driving device 5 also includes a driven gear 53 connected to the cleaning device 3, and a third gear 5221 provided on the second output end 522 of the converter 52 and meshing with the driven gear 53 through a linkage 54.

[0035] In this embodiment, the driven gear and the third gear are meshed with conical teeth, so that the meshing direction of the linkage member and the third gear can be set vertically, reducing the area occupied by the installation platform and making the space setting more reasonable. The cleaning device can achieve synchronous linkage through the gear transmission system under the drive of the converter, ensuring that the cleaning device can stably and continuously clean the perspective cylinder, thereby ensuring that the shooting device always obtains a clear conveyor belt image, improving the accuracy and efficiency of detection, and timely discovering and solving the problems of deviation, tearing, foreign matter, bulging, and exposed steel core of the conveyor belt during transmission. The cleaning device can run synchronously with the rotation of the perspective cylinder, ensuring the continuous cleaning of the outer surface of the perspective cylinder, avoiding the influence of dust and dirt on the observation effect of the shooting device, and improving the accuracy of fault detection. Secondly, the power is output through the second output end of the converter, and the power is transmitted to the cleaning device by the meshing transmission of the third gear and the driven gear 53, so as to achieve efficient use of power and simplification of the device, and reduce the manufacturing cost and maintenance difficulty.

[0036] Furthermore, as a preferred embodiment of the present invention but not a limitation, the cleaning device 3 includes a first cylindrical gear 31 connected to and synchronously rotating with the driven gear 53 and at least one second cylindrical gear 33 meshing with the first cylindrical gear 31 through a synchronous belt 32, and the synchronous belt 32 is provided with a cleaning member abutting against the outer surface of the transparent cylinder 2.

[0037] In this embodiment, the synchronous belt is provided with gear teeth that can mesh with the first cylindrical gear and the second cylindrical gear, and the cleaning member can be set as a rag or a brush, and the driven gear drives the first cylindrical gear to rotate synchronously, and the second cylindrical gear rotates synchronously with the first cylindrical gear under the action of the synchronous belt, so that the cleaning member on the synchronous belt continuously cleans the outer surface of the perspective cylinder. Through the connection between the driven gear and the first cylindrical gear, the power of the driving device is transmitted to the cleaning device, so that the automation of the cleaning process is realized, the manual intervention is reduced, and the work efficiency is improved. Secondly, the use of the synchronous belt ensures the synchronous rotation of multiple second cylindrical gears, so that the cleaning member can be evenly distributed on the outer surface of the perspective cylinder, providing a comprehensive cleaning effect and avoiding the appearance of cleaning dead angles. In addition, the direct contact between the cleaning member and the outer surface of the perspective cylinder can effectively remove dust, dirt and impurities, maintain the transparency of the perspective cylinder, ensure that the shooting device can obtain a clear image, and improve the accuracy and reliability of fault detection. When the driving device is started, the driven gear drives the first cylindrical gear to rotate, and then drives the second cylindrical gear to rotate synchronously through the synchronous belt. Assuming that there are two second cylindrical gears, which are respectively located on both sides of the perspective cylinder, as they rotate, the cleaning parts on the synchronous belt, such as bristles or flannel, continuously rub against the outer surface of the perspective cylinder 2 to remove the attached dust and stains. This design is particularly suitable for harsh environments such as mines. Due to the continuous operation of the conveyor belt, dust and particles are easily accumulated on the perspective cylinder, affecting the observation effect of the shooting device. The cleaning device can clean the perspective cylinder in real time and automatically, ensuring the continuity and stability of fault detection. Even if the conveyor belt runs for a long time, the detection device can still provide accurate monitoring results, reducing the need for equipment shutdown maintenance and improving the efficiency and benefits of mine production.

[0038] Furthermore, as a preferred embodiment of the present solution but not a limitation, the cleaning device 3 also includes a cleaning outer box 34, the first cylindrical gear 31 and the second cylindrical gear 33 are arranged in the cleaning outer box 34, and the driven gear 53 protrudes from the cleaning outer box 34 and meshes with the linkage 54.

[0039] Furthermore, as a preferred embodiment of the present invention but not a limitation, a connecting piece 11 is provided on the mounting platform 1 , and the clean outer box 34 is hinged to the connecting piece 11 via a hinge connecting rod 12 to adjust the angle of the clean outer box 34 relative to the transparent cylinder 2 .

[0040] In this embodiment, the linkage member includes a first linkage gear 541 meshed with the third gear, a second linkage gear meshed with the driven gear, and a linkage rod connecting the first linkage gear and the second linkage gear, and the hinge of the hinge connecting rod and the connecting member is coaxial with the rotation axis of the second linkage gear. The distance and angle between the cleaning outer box 34 and the perspective cylinder can be adjusted according to actual needs to ensure that the cleaning member can effectively contact the outer surface of the perspective cylinder and improve the cleaning effect. Secondly, the use of the hinge connecting rod makes the adjustment of the cleaning outer box more convenient, and the angle can be easily adjusted without disassembling or reinstalling the entire cleaning device, thereby improving the convenience of maintenance. In addition, this design can also adapt to perspective cylinders of different specifications and sizes, so that the fault detection device has better versatility and adaptability. If it is found that the cleaning effect of the bottom area of ​​the perspective cylinder is not good, the cleaning outer box can be tilted downward by adjusting the hinge connecting rod, so that the cleaning member can go deep into the bottom area for cleaning. This adjustable structural design enables the cleaning device to better adapt to various complex working environments and conditions, ensures the continuous cleaning of the perspective cylinder, and thus provides reliable protection for fault detection of mine conveyor belts.

[0041] Furthermore, as a preferred embodiment of the present invention but not a limitation, it also includes a guide rail 7, a first screw rod 8 and a second screw rod 9 that pass through the perspective cylinder 2 in a horizontal direction, and the shooting device 4 includes a camera 41 connected to the first screw rod 8 and a fill light 42 connected to the second screw rod 9, the camera 41 is slidably connected to the guide rail 7 through a first slider 81, and the fill light 42 is slidably connected to the guide rail 7 through a second slider 91.

[0042] In this embodiment, the camera and the fill light are slidably connected to the guide rail through their respective corresponding sliders, and can move in the horizontal direction inside the perspective cylinder, so that the shooting device can adjust its position as needed to obtain images of different areas of the conveyor belt, thereby improving the comprehensiveness and accuracy of the detection. Secondly, the setting of the first screw rod and the second screw rod can drive the camera and the fill light to accurately position and move on the guide rail, ensuring the clarity and brightness of the captured image, which is conducive to the staff's accurate judgment of conveyor belt failures.

[0043] Furthermore, as a preferred embodiment of the present invention but not a limitation, the bearing mounting seat 6 includes a bearing mounting shell 61, a bearing retaining ring 62 disposed in the mounting shell 61, a bearing outer ring 63 connected to the bearing retaining ring 62, and a bearing inner ring 64 connected to the perspective cylinder 2, and the bearing inner ring 64 rotates coaxially relative to the bearing outer ring 63.

[0044] In this embodiment, the coaxial rotation design of the bearing inner ring and the bearing outer ring reduces the friction and resistance of the perspective cylinder during rotation, allowing it to rotate smoothly, extending the service life of the bearing and reducing maintenance requirements.

[0045] Furthermore, as a preferred implementation mode of the present invention but not a limitation, it also includes a first dustproof shell 13 and a second dustproof shell 14 respectively arranged on both sides of the mounting platform 1, a transverse slide rail 15 arranged on the mounting platform 1, and a dust cover 17 on the mounting platform 1 that is slidably connected to the transverse slide rail 15 through a transverse slider 16.

[0046] In this embodiment, the first dustproof shell and the second dustproof shell can effectively prevent dust and particles in the mining environment from entering the device, protect other components from contamination, and improve the reliability and service life of the device. Secondly, the dust cover is slidably connected to the transverse slide rail through the transverse slider, and can be moved and adjusted as needed. Together with the first dust cover and the second dust cover, the entire device can be wrapped to provide dust protection when the device is not in use and is stored.

[0047] Furthermore, as a preferred implementation of the present solution but not a limitation, the cleaning device 3 further includes a dust collecting hopper 35 for collecting dust falling from the outer surface of the transparent cylinder 2 .

[0048] In this embodiment, the dust collecting hopper can collect the dust generated during the cleaning process in a centralized manner, thereby preventing the dust from flying up again or scattering into the surrounding environment, maintaining the cleanliness of the working environment, and reducing the potential impact on the health of workers. When the cleaning device is running, the cleaning parts on the synchronous belt will contact the outer surface of the perspective cylinder and brush off the attached dust. The fallen dust will enter the dust collecting hopper for collection. For example, when a mine conveyor belt is transporting ore or other dusty materials, a large amount of dust will be generated. If the dust is scattered directly onto the installation platform, it will not only pollute the environment, but may also cause damage to the respiratory system of the workers. Through the collection of the dust collecting hopper, the dust is stored in a centralized manner and can be regularly processed in a unified manner, such as recycling or filtering, thereby reducing direct emissions to the environment.

[0049] Furthermore, as a preferred implementation of the present solution but not a limitation, the shooting direction of the shooting device 4 is perpendicular to the curved surface of the perspective cylinder 2 .

[0050] In this embodiment, the vertical shooting direction can ensure that the camera obtains the clearest and most accurate image of the conveyor belt surface, because this angle eliminates the possibility of perspective distortion, so that the size and shape in the image can truly reflect the actual situation, which is conducive to the staff to quickly and accurately judge the condition of the conveyor belt.

[0051] Furthermore, as a preferred implementation of the present solution but not a limitation, the conveyor belt is located directly above the transparent cylinder.

[0052] In this embodiment, this position setting can capture the condition of the conveyor belt more clearly and intuitively, making it convenient to observe whether the conveyor belt has problems such as deviation, tearing, foreign matter, bulging, exposed steel core, etc., and to perform repairs and processing in a timely manner.

[0053] The working principle of this embodiment is as follows:

[0054] The present application discloses a mine conveyor belt fault detection device, which is placed under the conveyor belt in the mine for use. A photographing device is used to clearly observe whether the conveyor belt has deviation, tearing, foreign matter, bulging, exposed steel core and other problems, and presents them on a display screen. The setting of the perspective cylinder can isolate the dust in the mine from affecting the photographing device, and the cleaning device is used to continuously clean the outer surface of the perspective cylinder to prevent dust from covering and blocking the photographing device from photographing the conveyor belt.

[0055] The above are implementation methods provided in combination with specific contents, and it is not intended that the specific implementation of this application is limited to these descriptions. Any method structure similar to the present application, or a number of technical deductions or replacements based on the concept of the present application, should be considered as the protection scope of this application.
