[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0032] Refer to Figures 1 to 3 , an embodiment provided by the present invention: A speed sensor testing device for a mine belt conveyor, including a bottom plate 1, the top of the bottom plate 1 is fixedly connected with a detector housing 2. The bottom plate 1 is made of high-strength steel, with good load-bearing capacity and wear resistance, ensuring the stability and long-term use effect of the device. Both sides of the top of the bottom plate 1 are fixedly connected with support plates 3. These support plates 3 are made of corrosion-resistant alloy materials, which not only improve the overall corrosion resistance of the device, but also increase its service life in the harsh mine environment. The right end of one of the support plates 3 is coupled with a support rod 4, and the surface of the support rod 4 is anti-slip treated, so that the support rod 4 can be better fixed and stabilized during the operation of the adjustment component, ensuring the accurate positioning of the sensor body 7.

[0033] The top of the support rod 4 is provided with an adjustment component for adjusting components. The adjustment component is exquisitely designed and realizes fine adjustment of the connecting rod 6 through precise thread adjustment, ensuring the test accuracy while increasing the operation convenience. The bottom of the adjustment component is fixedly connected with a connecting rod 6. The connecting rod 6 is made of carbon fiber composite material, with the characteristics of light weight and high strength, effectively reducing the weight of the entire device while ensuring the stable connection of the sensor body 7. The adjustment component includes two restriction brackets 17. The two restriction brackets 17 are coupled to the outside of the support rod 4. The restriction brackets 17 are made of aluminum alloy material, which is both light and strong, and can effectively reduce the deformation caused by long-term use. Bolts 18 are threadedly connected to both sides of the two restriction brackets 17, and nuts 19 are threadedly connected to the outside of the bolts 18. These fasteners are rust-proof treated to ensure the long-term stable operation of the device in the humid mine environment and will not affect the device performance due to rust.

[0034] The bottom of one of the limiting frames 17 is fixedly connected to the top of the connecting rod 6. The firmness of the connection has been verified through multiple tests, which can effectively prevent the sensor body 7 from loosening during operation, thus affecting the detection results. One side of the connecting rod 6 is rotatably connected to the sensor body 7. The sensor body 7 adopts a standardized interface design, which is convenient for connecting with various types of speed sensors to ensure its accuracy during the detection process. The inner wall of the detector housing 2 is fixedly connected with a first motor 8. The first motor 8 adopts a high-efficiency motor, which can operate for a long time under high load without heating, improving the working efficiency of the entire testing device.

[0035] The driving end of the first motor 8 is fixedly connected with a driving roller 9. The driving roller 9 is wrapped with wear-resistant rubber, increasing the friction with the outside of the sensor body 7, enabling it to better simulate the operating state under actual working conditions. The top of the bottom plate 1 is fixedly connected with a second motor 10. The second motor 10 and the first motor 8 form a cooperative working mode, and through precise control, dynamic adjustment of the sensor test is achieved to ensure the accuracy of the detection data. The driving end of the second motor 10 is fixedly connected with a rotating plate 11. The rotating plate 11 is made of high-density material and has good impact resistance, ensuring that it is not easily deformed during high-speed operation and guaranteeing the stability of the device. The outside of the rotating plate 11 is movably connected with a moving plate 12. The moving plate 12 is made of a material with a low coefficient of friction, making its sliding process smoother, reducing the error caused by friction, and thus improving the accuracy of the test.

[0036] On both sides of the top of the bottom plate 1, there are fixedly connected guiding components for limitation. The guiding components are designed considering the particularity of the mine environment and adopt a dust-proof and waterproof structure to ensure that they can still work normally in a harsh environment. The support rollers 16 are rotatably connected at the through holes on both sides of the guiding components. The support rollers 16 are made of durable engineering plastics and have excellent wear resistance, ensuring smooth operation after long-term use. The outside of the sensor body 7 is in contact with the outside of the driving roller 9 and the support rollers 16 respectively for speed detection. This contact part is precisely processed to ensure the stability and accuracy of the data signal read by the sensor. The guiding components include two support blocks 15. The two support blocks 15 are respectively fixedly connected to both sides of the top of the bottom plate 1. The support blocks 15 are made of alloy materials with strong compressive resistance, effectively improving the overall strength of the device. The top of the support block 15 is fixedly connected with a slide rail 14. The slide rail 14 adopts a self-lubricating material, reducing friction loss and ensuring the smoothness and precision of the moving plate 12 during operation.

[0037] The adjacent sides of the two slide rails 14 are respectively fixedly connected to both sides of the moving plate 12. This symmetric structure design effectively disperses the force, improves the stability of the device, and prevents deviation during the detection process. The adjacent sides of the two slide rails 14 are both slidably connected with sliding blocks 13. The connection structure of the sliding blocks 13 is scientifically designed and adopts a high-precision processing technology to ensure its stability and accuracy during the sliding process. The two sides of the support roller 16 are respectively rotatably connected to the through holes of the two sliding blocks 13. The sliding connection design enables the support roller 16 to be finely adjusted as needed, ensuring the best contact state between the sensor and the roller during the detection process.

[0038] Reference Figure 4 and Figure 5 , and a fixing component for restricting the support rod 4 is fixedly connected to the right end of one of the support plates 3. The structure design of the fixing component is precisely adjusted to ensure the stability and reliability of the support rod 4 during the adjustment process. The fixing component includes a restricting rod 20. The left end of the restricting rod 20 is fixedly connected to the right end of one of the support plates 3. The restricting rod 20 is made of a high-strength material to ensure its compressive performance during use.

[0039] The outside of the restricting rod 20 is threadedly connected with a disc 21. The design of the disc 21 not only considers the convenience of operation but also uses a corrosion-resistant material, which is suitable for the complex environment in the mine. A restricting groove 22 is provided on the outside of the disc 21. The inner wall of the restricting groove 22 is slidably connected with a fixing rod 23. This sliding connection ensures the flexibility and reliability during the adjustment process and avoids loosening caused by vibration or other factors. The left end of the fixing rod 23 is fixedly connected to the right end of one of the support plates 3. The stable connection of the fixing rod 23 makes the whole device more stable during adjustment and detection, reducing the influence of external interference on the detection results. A push plate 24 is slidably connected to the right end of one of the support plates 3. The push plate 24 is designed with a user-friendly handle structure, which is convenient for the operator to quickly adjust the settings of the device in a complex environment. A telescopic rod is fixed to the rear end of the push plate 24 to support the push plate 24 for resetting.

[0040] The outside of the disc 21 is in contact with the front end of the push plate 24. This contact design is optimized to ensure the smooth operation of the push plate 24 during the adjustment process and prevent jamming. Slots are provided on both sides of the right end of one of the support plates 3. The left end of the push plate 24 is slidably connected to the two slots. This design can effectively prevent the push plate 24 from shaking and ensure the accuracy of the adjustment. Shell sleeves 25 are fixedly connected to the through holes on both sides of the push plate 24. The shell sleeves 25 are made of durable materials to prevent damage or wear during frequent operation.

[0041] A spring 26 is fixedly connected to the inner wall of one side of the shell 25. The spring 26 is made of high-elastic steel and has good fatigue resistance, ensuring that the elastic force can be maintained after long-term use. A moving block 27 is fixedly connected to the other end of the spring 26. The design of the moving block 27 takes into account the coordination with other components and adopts low-friction materials to ensure smooth sliding process inside the shell 25. The outer sliding connection of the moving block 27 is connected to the inner wall of the shell 25. The inner wall of the shell 25 is precisely processed to ensure that the sliding process of the moving block 27 is stable and does not produce abnormal noise.

[0042] The rear end of the moving block 27 is fixedly connected with a resistance block 28, and the resistance block 28 is designed with an ergonomic gripping part to facilitate the operator to quickly adjust the fixed state of the support rod 4. The right end of one of the support plates 3 is fixedly connected with a fixing plate 29, and the fixing plate 29 is made of high-strength metal material, which increases the overall rigidity of the support plate 3 and the stability of the device. The right end of one of the support plates 3 is fixedly connected with a limiting frame 5, and the design of the limiting frame 5 takes into account the coordinated use with the support rod 4 to ensure that stable contact is always maintained during the adjustment and testing process without loosening. The outside of the support rod 4 is in contact with the inner angle of the limiting frame 5. This contact mode optimizes the overall stability and precision of the device through reasonable design, ensuring the accuracy of the test results.

[0043] Working principle: when the equipment needs to be used, the rotating plate 11 is driven to rotate by starting the second motor 10, so that the sensor body 7 can receive the feedback of the rotation of the rotating plate 11, and then transmit the feedback information to the detector housing 2 for display. When the sensor body 7 needs to be adjusted, the limit frame 17 can be slid outside the bolt 18 by rotating the nut 19, so that the limit frame 17 can be adjusted, so that the connecting rod 6 drives the sensor body 7 to adjust. At this time, the height of the sensor body 7 changes, and then the rotating plate 11 is driven by starting the second motor 10 to move the movable plate 12. The movement of the movable plate 12 can drive the sliding block 13 to slide on the surface of the slide rail 14, thereby driving the support roller 16 to move, so that The support roller 16 can be adjusted to better support the sensor body 7 and improve the flexibility of the equipment. The limiting groove 22 can be moved by rotating the disk 21, which can drive the push plate 24 to move. The movement of the push plate 24 drives the shell 25 to make the resistance block 28 resist the support rod 4. After the resistance block 28 resists the support rod 4, it will push the moving block 27 so that the moving block 27 moves to squeeze the spring 26, thereby causing the spring 26 to deform and generate elastic potential energy. The elastic potential energy of the spring 26 can make the resistance block 28 strongly resist the support rod 4, thereby improving the fastening effect. Conversely, rotating the disk 21 will cause the resistance block 28 to stop resisting the support rod 4, so that the support rod 4 can be removed and the sensor body 7 can be adjusted.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are 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 perform equivalent replacements for some of the technical features.
