Technical Field
[0001] This utility model relates to the field of coal mine coal preparation equipment monitoring technology, and in particular to a scraper conveyor chain skipping fault identification device. Background Technology
[0002] Scraper conveyors are key equipment used for material conveying in industries such as mining, metallurgy, and building materials. They use chains to drive scrapers to move continuously within a trough, enabling the horizontal or inclined conveying of bulk materials (such as coal and ore). With their robust structure and strong conveying capacity, scraper conveyors are widely used in underground mining, factory production lines, and other scenarios, serving as core equipment connecting various production stages and ensuring the continuous flow of materials.
[0003] Existing scraper conveyor chain skipping fault identification devices mostly adopt a monitoring scheme combining cameras and infrared sensors. The camera is installed at a fixed position on the side of the scraper conveyor to capture the chain running. The infrared sensor is placed at the chain tensioning point to detect changes in chain displacement and determine whether there is slack or a tendency to skip the chain. The data from both are linked to achieve preliminary fault identification.
[0004] However, existing cameras are fixed installations, which limit the monitoring angle and easily create blind spots. When the scraper conveyor malfunctions, it is difficult to capture the location of the skipped chain in time. Therefore, a scraper conveyor skipped chain fault identification device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a scraper conveyor chain skipping fault identification device, which aims to improve the problem that the camera angle is fixed in the prior art and cannot be adjusted according to the fault location.

An electric push rod is fixedly connected inside the mounting box, and a rack is fixedly connected to the output end of the electric push rod. The rack and the gear mesh with each other. As a further description of the above technical solution: The position adjustment assembly includes a motor, which is fixedly connected to one end of the mounting housing. A bidirectional threaded rod is rotatably connected inside the mounting housing. One end of the bidirectional threaded rod is fixedly connected to the output end of the motor. Two moving blocks are threadedly connected to the outer side of the bidirectional threaded rod. An electric push rod is installed inside the moving blocks. The infrared sensor is installed at the output end of the electric push rod. As a further description of the above technical solution: The vertical angle adjustment component includes a second motor, which is fixedly connected to the outside of the fixed column. The output end of the second motor is fixedly connected to a rotating shaft, and the other end of the rotating shaft is fixedly connected to the outside of the camera.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a scraper conveyor chain skipping fault identification device, including a mounting shell 1. A position adjustment component is installed inside the mounting shell 1, and an infrared sensor 7 is installed on the outside of the position adjustment component. Two infrared sensors 7 are set to detect two chains respectively. Once a chain skipping or other situation occurs, it can react quickly and trigger an alarm. A bracket 13 is fixedly connected to the middle of the mounting shell 1, and a mounting box 14 is fixedly connected to the bottom of the bracket 13. A horizontal angle adjustment component is installed inside the mounting box 14, allowing the camera 21 to rotate flexibly horizontally. A fixed column 19 is rotatably connected to the bottom of the mounting box 14, and a vertical angle adjustment component is installed on the outside of the fixed column 19, allowing the camera 21 to rotate vertically. The camera 21 is installed on the outside of the vertical angle adjustment component. The camera 21 is a starlight-level camera, which can provide color images under low light conditions, providing richer detailed information for subsequent image analysis compared to traditional black and white monitoring images. The horizontal angle adjustment component includes a gear 15, which is rotatably connected inside the mounting box 14. An electric push rod 18 is fixedly connected inside the mounting box 14. A rack 17 is fixedly connected to the output end of the electric push rod 18. When the electric push rod 18 is activated, it can push the rack 17 to move, thereby rotating the gear 15. The rack 17 and the gear 15 mesh with each other. A base 16 is fixedly connected to the bottom of the gear 15. The rotation of the gear 15 drives the base 16 to rotate, thereby rotating the camera 21. The base 16 is fixedly connected to the top of the fixing column 19.
[0013] The vertical angle adjustment component includes a second motor 20, which is fixedly connected to the outside of the fixed column 19. The output end of the second motor 20 is fixedly connected to a rotating shaft 4. Starting the second motor 20 can drive the rotating shaft 4 to rotate, thereby causing the camera 21 to rotate. The other end of the rotating shaft 4 is fixedly connected to the outside of the camera 21. A protective box 22 is fixedly connected to the outside of the fixed column 19. The protective box 22 can protect the second motor 20 from external dust contamination. The second motor 20 is installed inside the protective box 22.
[0014] Reference Figure 1 and Figure 2The position adjustment component includes a motor 9, which is fixedly connected to one end of the mounting housing 1. A bidirectional threaded rod 10 is rotatably connected inside the mounting housing 1. Starting the motor 9 drives the bidirectional threaded rod 10 to rotate. One end of the bidirectional threaded rod 10 is fixedly connected to the output end of the motor 9. Two moving blocks 5 are threadedly connected to the outer side of the bidirectional threaded rod 10. The two moving blocks 5 can move synchronously when the bidirectional threaded rod 10 rotates. An electric push rod 6 is installed inside the moving block 5. Starting the electric push rod 6 can push the infrared sensor 7 to adjust its vertical position to adapt to equipment of different heights. The infrared sensor 7 is installed at the output end of the electric push rod 6. A motor box 8 is fixedly connected to one end of the mounting housing 1. The motor box 8 not only protects the motor 9 from contamination but also provides an installation position for the motor 9. The motor 9 is installed inside the motor box 8.
[0015] Reference Figures 1-3 Both the mounting shell 1 and the motor box 8 are equipped with fixing plates 2 on their outer sides. The fixing plates 2 have multiple mounting holes 3 inside. The device can be installed on a wall or mechanical equipment through the fixing plates 2 and the mounting holes 3. The mounting shell 1 is equipped with a folding dust cover 12. One end of the folding dust cover 12 is fixedly connected to the moving block 5. When the moving block 5 moves, it will extend or retract, thereby protecting the inside of the mounting shell 1 from dust without affecting the operation of the device. The mounting shell 1 is fixedly connected with a guide rod 11 inside. The guide rod 11 is set to make the movement of the moving block 5 more stable. The moving block 5 is slidably connected to the outside of the guide rod 11.
[0016] Working principle: First, based on the location of frequent malfunctions, such as areas where chain skipping occurs, adjust the orientation of camera 21. Start motor 20 to rotate shaft 4, thereby rotating camera 21 vertically and adjusting its vertical angle. Additionally, start electric push rod 18, which moves rack 17, causing gear 15 to rotate. Gear 15 then rotates fixed column 19, allowing for horizontal angle adjustment of camera 21. When temporary adjustments to camera 21's position are needed, there is no need to reinstall camera 21, saving time, improving efficiency, and reducing installation costs.
[0017] Secondly, by starting motor 9, motor 9 drives bidirectional threaded rod 10 to rotate. Bidirectional threaded rod 10 drives two infrared sensors 7 to move towards each other or away from each other until the two infrared sensors 7 are vertically aligned with the two chains respectively. Then, by starting electric push rod 26, the infrared sensors 7 are pushed to the appropriate position for monitoring. Not only can the spacing be adjusted according to different types of scraper machines, but the equipment can also be adjusted according to the height of the device, which improves the adaptability of the device.
[0018] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
