[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] As shown in Figures 1-4, an online inspection device for steel wire ropes used in mining includes an inspection disc 1. The surface of the inspection disc 1 has a recessed inspection groove 2. The inspection groove 2 has an inspection hole 3 that penetrates the inspection disc 1 in the middle. An annular plate 4 is installed on the inner wall of the inspection groove 2 and is fitted around the outside of the inspection hole 3. Several flaw detection sensors 5 are installed on the inner side of the annular plate 4 facing the inspection hole 3. A protective kit is provided on the upstream side of the inspection disc 1 facing the moving direction of the steel wire rope 23. The protective kit includes a fixed sleeve 6 fitted around the annular plate 4 and a movable sleeve 7 movably connected to the end of the fixed sleeve 6. A driving mechanism is provided on the outside of the movable sleeve 7 and the outside of the fixed sleeve 6. The movable sleeve 7 rotates at the end of the fixed sleeve 6 through the driving mechanism. A cleaning component is provided inside the movable sleeve 7 to clean the surface of the steel wire rope 23. The cleaning component cleans the surface of the steel wire rope 23 as the movable sleeve 7 rotates.

[0020] Based on the above, the inspection plate 1 provides basic support for the entire device. The inspection groove 2 on its surface is used to install the annular plate 4 and form an airflow accommodating space. The inspection hole 3 in the middle provides a passage for the wire rope 23 and is aligned with the moving direction of the wire rope 23 to ensure that the wire rope 23 is always on the preset path during inspection. The annular plate 4 is fitted outside the inspection hole 3, and the flaw detection sensors 5 on its inner sidewall are evenly distributed around the inspection hole 3, which can fully cover the surface of the wire rope 23, avoid blind spots, and provide a basis for accurate data acquisition for subsequent defect identification. The protective kit is installed on the inspection plate. On the upstream side, the fixed sleeve 6 serves as a protective and connecting carrier, and is fitted onto the outside of the annular plate 4 to achieve structural connection. The movable sleeve 7 can rotate flexibly through the drive mechanism. When the cleaning component inside rotates with the sleeve, it can adhere to the surface of the moving wire rope 23 and scrape off the dust, slag and other impurities adhering to the wire rope 23 in the mining scene in advance. Since impurities in the mining environment can easily block the signal of the flaw detection sensor 5, the rotation cleaning of the cleaning component can reduce detection interference from the source. The drive mechanism provides stable rotation power for the movable sleeve 7 to ensure uniform cleaning force and lay the foundation for subsequent accurate detection.

[0021] Among them, the flaw detection sensor 5 is an electromagnetic induction flaw detection sensor, a magnetic flux leakage flaw detection sensor, or an ultrasonic flaw detection sensor with a wear-resistant protective structure, which can be freely selected and replaced according to the specific mining application scenario.

[0022] The detection groove 2 and detection hole 3 are both circular and concentric with the annular plate 4. A sealing plate 8 is provided between the outer wall of the annular plate 4 and the inner wall of the detection groove 2. The space between the sealing plate 8, the annular plate 4 and the detection groove 2 forms a diversion air chamber 9. An air pipe 10 communicating with the inside of the diversion air chamber 9 is installed on the outer wall of the detection plate 1. A bent air blowing pipe 11 is provided on the inner side of the annular plate 4. One end of the air blowing pipe 11 passes through the annular plate 4 and communicates with the diversion air chamber 9, and the other end extends into the fixed sleeve 6 and faces the cleaning part.

[0023] Based on the above, the concentric circle design of the detection groove 2, detection hole 3, and annular plate 4 ensures that the flaw detection sensor 5 on the inner side of the annular plate 4 is coaxially aligned with the passing steel wire rope 23. No matter how slightly the steel wire rope 23 shakes, the sensor can stably collect signals, avoiding missed detections due to positional deviation. The sealing plate 8 seals the gap between the annular plate 4 and the detection groove 2, so that the three form a closed diversion air chamber 9. This air chamber can evenly distribute the externally input airflow to each blowing pipe 11 on the inner side of the annular plate 4, avoiding airflow concentration that leads to incomplete local cleaning. The air pipe 10 on the outer side of the detection plate 1 serves as an airflow transmission channel. One end is connected to the air pump 15 to obtain high-pressure airflow, and the other end is connected to the diversion air chamber 9, providing a stable air source for subsequent air-blowing auxiliary cleaning, realizing the synergistic preparation of "mechanical cleaning + air-blowing dust removal".

[0024] Furthermore, the air blowing pipe 11 adopts a bent structure, with one end penetrating through the annular plate 4 and communicating with the diversion air chamber 9, which can directly obtain the high-pressure airflow in the air chamber. The other end extends into the fixed sleeve 6 and faces the cleaning component, so that the airflow can accurately act on the cleaning area. When the cleaning component rotates to scrape off the impurities on the surface of the wire rope 23, the high-pressure airflow sprayed from the air blowing pipe 11 can blow away the scraped dust in time, preventing the impurities from adhering to the surface of the wire rope 23 or the cleaning component again. At the same time, the airflow can also penetrate into the gaps on the surface of the wire rope 23 to clean the small impurities that the cleaning brush bristles 13 cannot reach, further improving the cleaning effect and ensuring that the surface of the wire rope 23 entering the detection hole 3 is not blocked by impurities, thus ensuring the accuracy of the signals collected by the flaw detection sensor 5.

[0025] The cleaning component includes a cleaning plate 12 fixed to the inner wall of the movable sleeve 7 and cleaning bristles 13 installed at the inner edge of the cleaning plate 12.

[0026] Based on the above, the cleaning plate 12 is fixed to the inner wall of the movable sleeve 7, providing a base for the installation and support of the cleaning bristles 13, ensuring the stability of the bristle position. The cleaning bristles 13 are installed on the inner edge of the cleaning plate 12, and their length is designed to fit the surface of the steel wire rope 23. When the movable sleeve 7 is driven by the drive mechanism to rotate, the cleaning plate 12 drives the cleaning bristles 13 to rotate synchronously. The relative friction between the bristles and the moving steel wire rope 23 can effectively scrape away stubborn impurities such as mining dust and lumpy slag adhering to the surface of the steel wire rope 23. Compared with the fixed cleaning structure, the rotary cleaning can cover the entire circumference of the steel wire rope 23 through circumferential motion, avoiding cleaning dead corners. Moreover, the flexible material of the bristles can adapt to the slight undulations of the surface of the steel wire rope 23, ensuring the cleaning effect without scratching the steel wire rope 23 body.

[0027] A mounting plate 14 is provided above the detection plate 1. Several screw holes are provided on the mounting plate 14. An air pump 15 is installed on the mounting plate 14. The output end of the air pump 15 is connected to the top of the air pipe 10 through a pipeline.

[0028] Based on the above, the mounting plate 14 is fixed above the detection plate 1, and the screw holes on its surface are used to fix the entire device to the bracket or equipment next to the transmission path of the mining wire rope 23, ensuring that the device remains stable in the vibration environment of the mine and avoiding positional displacement that affects the detection accuracy; the air pump 15, as the power source for air blowing cleaning, is installed on the mounting plate 14 and can be connected to the air pipe 10 nearby to reduce airflow transmission loss; the output end of the air pump 15 is connected to the air pipe 10 through the pipeline, and can generate high-pressure airflow after starting. The airflow enters the diversion air chamber 9 through the air pipe 10, and then acts on the cleaning area through the blowing pipe 11, providing a continuous and stable airflow for air blowing auxiliary cleaning, forming a dual cooperation with mechanical cleaning to thoroughly remove impurities.

[0029] The inner wall of the fixed sleeve 6 and the outer wall of the annular plate 4 are both provided with mating threads. The fixed sleeve 6 is detachable from the annular plate 4. A bearing ring 16 is installed at the end of the fixed sleeve 6. The movable sleeve 7 is movably connected to the fixed sleeve 6 through the bearing ring 16.

[0030] Based on the above, the threaded design of the fixed sleeve 6 and the annular plate 4 enables a detachable connection between the two. When the cleaning parts are worn and need to be replaced or the flaw detection sensor 5 needs maintenance, the fixed sleeve 6 can be unscrewed directly without disassembling the entire detection disc 1, greatly improving the convenience of maintenance. The bearing ring 16 at the end of the fixed sleeve 6 adopts a rolling friction structure. The movable sleeve 7 is connected to the fixed sleeve 6 through the bearing ring 16, which can convert the sliding friction when the movable sleeve 7 rotates into rolling friction. This reduces component wear and ensures smooth rotation of the movable sleeve 7, avoiding unstable cleaning speed due to excessive frictional resistance and ensuring uniform cleaning effect.

[0031] The drive mechanism includes a support frame 17 fixed on the outer wall of the fixed sleeve 6 and a gear ring 18 sleeved on the outer wall of the movable sleeve 7. A servo motor 19 is mounted on the support frame 17, and a gear 20 that meshes with the gear ring 18 is mounted on the end of the output shaft of the servo motor 19.

[0032] Based on the above, the support frame 17 is fixed to the outer wall of the fixed sleeve 6, providing a stable mounting base for the servo motor 19 and ensuring that the motor does not shift in the vibration environment of the mine. The servo motor 19 serves as the driving power source, and the gear 20 at the end of its output shaft meshes with the gear ring 18 on the outer wall of the movable sleeve 7. After starting, the servo motor 19 drives the gear 20 to rotate, and through the meshing transmission of the gear and gear ring, the power is transmitted to the movable sleeve 7, driving the movable sleeve 7 to rotate around the bearing ring 16. The servo motor 19 can precisely control the speed and can adjust the rotation speed of the movable sleeve 7 according to the amount of impurities on the surface of the wire rope 23. When there are more impurities, the speed is increased to enhance the cleaning power, and when there are fewer impurities, the speed is reduced to save energy. Moreover, the gear-gear ring transmission structure is stable and can avoid slippage during power transmission, ensuring that the cleaning components work continuously and stably.

[0033] A protective ring cover 21 is provided on the outer side of the connection between the fixed sleeve 6 and the movable sleeve 7. One end of the protective ring cover 21 is fixedly installed on the outer wall of the fixed sleeve 6, and the other end is connected to the outer wall of the movable sleeve 7 through a mechanical sealing ring 22. The support frame 17, the toothed ring 18, the servo motor 19 and the gear 20 are all located inside the protective ring cover 21.

[0034] Based on the above, the protective ring cover 21 is fitted on the outside of the connection between the fixed sleeve 6 and the movable sleeve 7, completely enclosing the drive components such as the support frame 17, gear ring 18, servo motor 19, and gear 20. This can prevent pollutants such as dust, slag, and water vapor in the mining environment from entering the drive mechanism, avoiding gear meshing jamming, short circuit of the servo motor 19, or corrosion of components caused by pollutants, thus extending the service life of the drive mechanism. The mechanical seal ring 22 at the other end of the protective ring cover 21 is made of flexible sealing material. While tightly fitting the outer wall of the movable sleeve 7, it does not affect the rotation of the movable sleeve 7, achieving "dynamic sealing" and further isolating external pollutants, ensuring the cleanliness of the drive mechanism's interior, and guaranteeing the stability and reliability of power transmission.
