Description

Technical Field

[0001] This invention belongs to the field of mining, specifically a positioning device for intelligent loader in underground mines. Background Technology

[0002] The underground mine is the core area of ​​mining production activities. Loaders are frequently used during underground mining operations, but due to the complex underground environment, numerous safety hazards exist. Therefore, positioning devices can monitor the location and dynamic information of loaders in real time, helping managers to promptly identify potential safety risks and take corresponding safety measures.

[0003] Patent CN216238737U discloses a positioning device for an intelligent loader in underground mining, comprising a base and RFID identification cards. The RFID identification cards are mounted on a protrusion on the inner bottom surface of the base. Baffles are provided at both ends of the base, and a protective cover, which is arched, is provided on the inner bottom surface of the base. In this patent, each RFID identification card, possessing a unique number and location information, communicates with the intelligent terminal of the loader, thus determining the current position of the loader. Furthermore, the base, baffles, and protective cover provide effective protection against complex environments such as dust, water mist, blast shock waves, and high temperatures, ensuring the reliability of the underground loader dispatching information system while improving the loader's shift efficiency and safety.

[0004] However, the above technical solutions still have the following shortcomings in practical applications: By installing RFID tags on the tunnel walls and connecting them to the loader's smart terminal, the loader's current location can be determined. Furthermore, a protective cover is installed to prevent the RFID tags from being affected by blast waves, flying rocks, or other foreign objects. However, due to the unique environment of an underground mine, dust inevitably accumulates on the surface of the protective cover. If the dust layer is thick and contains metal particles or conductive substances, it can cause RFID signal attenuation, thus affecting the positioning accuracy. Summary of the Invention

Detailed Implementation

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please refer to Figures 1-10 The present invention provides a technical solution: a positioning device for an intelligent loader in underground mines, including a base 1, a plurality of mounting holes 7 on the base 1, an RFID identification card 31 installed on one side of the outer wall of the base 1, a protective cover 5 fixedly connected to one side of the outer wall of the base 1, the protective cover 5 covering the RFID identification card 31, the protective cover 5 being made of ABS engineering plastic, and a surrounding cleaning component for removing impurities attached to the outer surface of the protective cover 5 on the base 1; The surrounding cleaning assembly includes multiple guide rods 26 slidably connected to the base 1. One end of the guide rod 26 is fixedly connected to the mounting shell 3. A rotating ring 4 is rotatably arranged in the inner cavity of the mounting shell 3. Both sides of the rotating ring 4 are fixedly connected to the outer shell 6. A rack 11 is slidably connected to the inner cavity of the outer shell 6. A brush 12 is fixedly connected to one end of the rack 11. Maintenance components are also provided on base 1; The maintenance components include protective boxes 15 fixedly connected to both sides of the outer wall of the base 1, with a cover 16 rotatably mounted on one end of the protective box 15.

[0024] In this embodiment, as Figures 1-5 , Figure 7 , Figures 9-10 As shown, an electric actuator 28 is fixedly connected to one side of the inner cavity of the base 1, and the piston end of the electric actuator 28 is fixedly connected to one side of the mounting shell 3.

[0025] A second outer shell 8 is fixedly connected to one side of the outer wall of the mounting shell 3. A gear 10 is rotatably installed inside the cavity of the second outer shell 8. The gear 10 meshes with the toothed blocks on the outer ring of the rotating ring 4. A motor 9 is fixedly connected to one side of the outer wall of the second outer shell 8. The output end of the motor 9 is fixedly connected to the gear 10.

[0026] Both sides of the rotating ring 4 are fixedly connected to the outer shell 3 13. The inner cavity of the outer shell 3 13 is rotatably equipped with the gear 20. The gear 20 meshes with the tooth block on the rack 11. The outer wall of the outer shell 3 13 is fixedly connected to the motor 2 14. The output end of the motor 2 14 is fixedly connected to the gear 20.

[0027] Specifically, in existing technology, the current position of the loader is determined by installing an RFID identification card 31 on the tunnel wall and connecting the RFID identification card 31 to the intelligent terminal of the loader. Furthermore, a protective cover 5 is installed to prevent the RFID identification card 31 from being affected by blast shock waves, flying rocks, or other foreign objects. However, due to the special environment of an underground mine, the protective cover 5 inevitably accumulates dust on its surface. If the dust layer is thick and contains metal particles or conductive substances, it will cause RFID signal attenuation, thus affecting the positioning effect.

[0028] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: Using mounting holes 7 and expansion screws, the base 1 is installed on the tunnel wall, enabling the RFID identification card 31 to communicate with the loader's intelligent terminal, allowing real-time monitoring of the loader's location. Furthermore, because the protective cover 5 shields the RFID identification card 31, it is protected from blast shock waves, flying rocks, or other foreign object impacts, thus extending its service life. In addition, the protective cover 5 is made of ABS engineering plastic, which is both rigid and has minimal impact on the RFID signal, thus simultaneously meeting the requirements for protection and signal transmission. Moreover, because the protective cover 5 is curved, when flying rocks or other foreign objects impact the protective cover 5, the curved surface disperses the impact force along the curved surface, reducing local stress concentration and thus lowering the risk of the protective cover 5 cracking or deforming.

[0029] Every so often, motor 14 drives gear 20 to rotate, causing rack 11 to slide inside the outer shell 6, so that the bristles of brush 12 fit against the outer surface of protective cover 5. Then, motor 9 drives gear 10 to rotate, causing rotating ring 4 to rotate. The two brushes 12 move in a circular motion along the surface of protective cover 5 to clean the dust adhering to the outer surface of protective cover 5. Since protective cover 5 is curved, the brushes 12 can adapt to the shape changes of protective cover 5 by driving rack 11 to slide on outer shell 6 and by moving mounting shell 3 laterally. This ensures that brushes 12 can clean all areas of the outer surface of protective cover 5, thereby achieving the periodic removal of dust adhering to the outer surface of protective cover 5. This avoids the situation where thick dust adhering to the outer surface of protective cover 5 leads to RFID signal attenuation and affects the positioning effect.

[0030] In this embodiment, as Figures 4-6 , Figure 8 , Figure 9 As shown, a motor 18 is fixedly connected to one side of the protective box 15, and the output end of the motor 18 is fixedly connected to one end of the box cover 16.

[0031] A dust collection box 27 is fixedly connected to one side of the inner cavity of the base 1. A vacuum cleaner 30 is connected and fixed to one side of the dust collection box 27. A second suction pipe 29 is connected to the air inlet of the vacuum cleaner 30. Two first suction pipes 19 are connected and fixed to both sides of the second suction pipe 29. The first suction pipe 19 passes through the base 1 and the protective box 15 and is fixed to both. The opening of the first suction pipe 19 is located in the inner cavity of the protective box 15.

[0032] The inner cavity of the protective box 15 is also equipped with a toggle assembly; The actuating assembly includes a slider 23 that is slidably connected to one side of the inner cavity of the protective box 15 via a slide groove. A drive shaft 32 is rotatably mounted on one side of the slider 23, and a cam 22 is sleeved and fixed on one side of the drive shaft 32.

[0033] A gear 24 is sleeved and fixedly connected to one side of the drive shaft 32, and a rack 21 is fixedly connected to one side of the inner wall of the protective box 15. The gear 24 meshes with the toothed blocks on the rack 21.

[0034] A threaded rod 25 is threadedly connected to one side of the slider 23. Both ends of the threaded rod 25 are rotatably mounted on the protective box 15. A motor 3 17 is fixedly connected to one side of the outer wall of the protective box 15. The output end of the motor 3 17 is fixedly connected to one end of the threaded rod 25.

[0035] Ventilation openings are provided on both sides of the base 1, and filters 2 are installed at the ventilation openings.

[0036] Specifically, in the above embodiments, although the brush 12 can be used periodically to clean the dust attached to the outer surface of the protective cover 5, due to the special nature of the underground mining environment, dust tends to stick to the brush bristles when the brush 12 is idle or during cleaning. As a result, when the brush 12 is working, the dust attached to the brush 12 is likely to fall back onto the surface of the protective cover 5, thus affecting the continuous cleaning effect of the dust on the surface of the protective cover 5.

[0037] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: When the brush 12 is not in operation, it is located within the protective housing 15, with the rack 11 inserted into the groove of the protective housing 15. The cover 16 seals the protective housing 15, thus isolating the brush 12 from the external environment and preventing dust from adhering to the bristles. When dust cleaning is required, the motor 18 rotates the cover 16, opening the protective housing 15. This then drives the mounting housing 3 to move laterally, removing the brush 12 from the protective housing 15, allowing the brush 12 to perform normal dust cleaning. After brush 12 completes one cleaning cycle, it returns to its initial position, and rack 11 re-engages with the groove in protective box 15. Then, cover 16 seals protective box 15. Since dust remains on the bristles of brush 12 after cleaning, vacuum cleaner 30 draws this dust into dust collection box 27 via suction pipes 19 and 29. Simultaneously, motor 317 drives threaded rod 25 to rotate, causing slider 23 to slide back and forth. As slider 23 slides, gear 324 meshes with rack 21, causing cam 22 to rotate. 2. The cam 22 continuously moves the brush bristles of the brush 12 in a combined horizontal and rotational motion, causing the bristles to vibrate and the dust attached to the bristles to fall off. Since the fallen dust is still in the protective box 15 and the protective box 15 has a small space, the dust can be easily sucked into the dust collection box 27. Thus, under the action of negative pressure adsorption and mechanical agitation, the dust attached to the bristles can be effectively removed, avoiding the situation where the dust attached to the bristles falls back onto the surface of the protective cover 5 during subsequent use, thereby affecting the continuous cleaning effect of the dust on the surface of the protective cover 5.

[0038] In addition, since the ventilation opening of the base 1 is equipped with a filter 2, the vacuum cleaner 30 can not only work normally, but also prevent external dust from entering the base 1 and affecting the vacuum cleaner 30.

[0039] Working Principle: The base 1 is installed on the tunnel wall using mounting holes 7 and expansion screws, enabling the RFID card 31 to communicate with the loader's intelligent terminal, allowing real-time monitoring of the loader's location. Furthermore, because the protective cover 5 shields the RFID card 31, it is protected from blast shock waves, flying rocks, or other impacts, thus extending its lifespan. In addition, the protective cover 5 is made of ABS engineering plastic, which is both rigid and has minimal impact on the RFID signal, thus meeting both protection and signal transmission requirements. Moreover, because the protective cover 5 is curved, when flying rocks or other foreign objects impact it, the curved surface disperses the impact force along the curved surface, reducing local stress concentration and lowering the risk of breakage or deformation. Every so often, motor 14 drives gear 20 to rotate, causing rack 11 to slide inside the outer shell 6, so that the bristles of brush 12 fit against the outer surface of protective cover 5. Then, motor 9 drives gear 10 to rotate, causing rotating ring 4 to rotate. The two brushes 12 move in a circular motion along the surface of protective cover 5 to clean the dust adhering to the outer surface of protective cover 5. Since protective cover 5 is curved, the brushes 12 can adapt to the shape changes of protective cover 5 by driving rack 11 to slide on outer shell 6 and by moving mounting shell 3 laterally. This ensures that brushes 12 can clean all areas of the outer surface of protective cover 5, thereby achieving the periodic removal of dust adhering to the outer surface of protective cover 5. This avoids the situation where thick dust adhering to the outer surface of protective cover 5 leads to RFID signal attenuation and affects the positioning effect. When the brush 12 is not in operation, it is located within the protective housing 15, with the rack 11 inserted into the groove of the protective housing 15. The cover 16 seals the protective housing 15, thus isolating the brush 12 from the external environment and preventing dust from adhering to the bristles. When dust cleaning is required, the motor 18 rotates the cover 16, opening the protective housing 15. This then drives the mounting housing 3 to move laterally, removing the brush 12 from the protective housing 15, allowing the brush 12 to perform normal dust cleaning.After brush 12 completes one cleaning cycle, it returns to its initial position, and rack 11 re-engages with the groove in protective box 15. Then, cover 16 seals protective box 15. Since dust remains on the bristles of brush 12 after cleaning, vacuum cleaner 30 draws this dust into dust collection box 27 via suction pipes 19 and 29. Simultaneously, motor 317 drives threaded rod 25 to rotate, causing slider 23 to slide back and forth. As slider 23 slides, gear 324 meshes with rack 21, causing cam 22 to rotate. 2. The cam 22 performs a combined lateral and rotational motion, continuously agitating the ends of the brush bristles 12, causing them to vibrate and dislodging the dust adhering to them. Since the dislodged dust remains within the protective box 15, and the protective box 15 has a small space, the dust can be easily sucked into the dust collection box 27. Thus, under the action of negative pressure adsorption and mechanical agitation, the dust adhering to the brush bristles is effectively removed, preventing dust from adhering to the brush bristles and falling back onto the surface of the protective cover 5 during subsequent use, thereby affecting the continuous cleaning effect on the surface of the protective cover 5. Furthermore, because the ventilation opening of the base 1 is equipped with a filter 2, the vacuum cleaner 30 can not only operate normally but also prevents external dust from entering the base 1 and affecting the vacuum cleaner 30.
