Description

Technical Field

[0001] The utility model relates to the field of conveyor belts, in particular to a flame-retardant lifting conveyor belt for mines. Background Art

[0002] In mining operations, conveyor belts are critical equipment for material transportation, and their performance directly impacts the efficiency and safety of the entire production process. This is especially true in mining environments where flammable and explosive materials pose a risk, placing even more stringent demands on lifting conveyor belts. Flame-retardant lifting conveyor belts for mines were developed to meet the complex and dangerous working conditions of mines. They ensure efficient transportation of ore and other materials while ensuring operational safety, preventing fires and other accidents caused by conveyor belt-related issues, and providing strong support for safe production and sustainable operations in mines.

[0003] Traditional mining conveyor belts primarily consist of a rubber or plastic conveyor belt body, a drive roller, driven rollers, idlers, and a tensioning device. The technical principle is that the drive roller, driven by a motor or other power source, rotates, utilizing friction between the roller and the conveyor belt to drive the conveyor belt. Driven rollers provide auxiliary support and guidance. Idlers are positioned along the conveyor belt to support the weight of the belt and the material on it, reducing belt sagging. The tensioning device adjusts the belt's tension to ensure sufficient friction between the belt and the rollers for proper operation.

[0004] Traditional conveyor belts collide with each other during transportation, splashing gravel and causing injuries to workers. In addition, a large amount of dust is generated during transportation, and traditional devices cannot effectively handle this dust. Therefore, a flame-retardant lifting conveyor belt for mines is proposed to solve the above problems. Utility Model Content

The bottom of the protective cover 6 is slidably connected to the upper surface of the conveyor belt 1, and a concave hole 7 is opened inside the conveyor belt 1. The protective cover 6 is fixedly connected inside Connect to the limit block 8, the limit block 8 is internally slidably connected with a card block 9, the card block 9 is used to position for facilitating the installation of the protective cover 6, the limit block 8 is provided with a first spring 10, the first spring 10 is used for rebound reset, the side wall of the card block 9 is slidably connected to the inside of the concave hole 7, the protective cover 6 is internally threaded with a mounting bolt 11, the upper surface of the protective cover 6 on one side is fixedly connected with a fixing column 12, a fixing hole 13 is opened inside the protective cover 6 on one side, the fixing column 12 is slidably connected to the inside of the fixing hole 13, the protective cover 6 is internally threaded with a fixing bolt 14, the side wall of the slide rod 4 is fixedly connected to the side wall of the push plate 2, the output end of the hydraulic rod 5 is connected to the push plate 2, one end of the first spring 10 is fixedly connected to the inside of the limit block 8, and the other end of the first spring 10 is fixedly connected to the side wall of the card block 9;

[0035] During the process of transporting ore, the conveyor belt 1 will generate a lot of dust due to the frequent collisions between the ores. This dust will not only pollute the surrounding environment, but also cause serious harm to the health of the workers. Therefore, it is necessary to install a protective cover 6 to effectively control the dust. During the installation and movement of the protective cover 6, the clamping block 9 plays a key positioning role. When the protective cover 6 moves, the clamping block 9 is squeezed from the outside and enters the inside of the limit block 8. When the protective cover 6 moves to just above the concave hole 7, the first spring 10 loses its extrusion. The first spring 10 is originally in a compressed state. At this time, it will use its own elastic restoring force to clamp the clamping block 9 into the inside of the concave hole 7, thereby preliminarily fixing the protective cover 6. This fixing method is convenient and fast, and can quickly position the protective cover 6 during the installation process to ensure its accurate position. After the clamping block 9 completes the preliminary fixation, the mounting bolt 11 is twisted into the inside of the protective cover 6. The mounting bolt 11 further enhances The fixing effect of the protective cover 6 is improved, so that it is more firmly installed in the corresponding position, preventing the protective cover 6 from loosening or displacement during use. At the same time, when installing the protective covers 6 on both sides, the fixing columns 12 and the fixing holes 13 cooperate with each other, and the fixing columns 12 are inserted into the fixing holes 13 to connect the protective covers 6 on both sides, ensuring that the connection between the protective covers 6 on both sides is tight and stable, avoiding gaps during use and preventing dust from leaking from the gaps. Then the fixing bolts 14 are twisted in to fix them. The fixing bolts 14 further strengthen the firmness of the connection between the protective covers 6 on both sides, and better block the dust generated during transportation of the conveyor belt 1. When the conveyor belt 1 is in use, the hydraulic rod 5 is started to push the push plate 2. Under the action of the hydraulic rod 5, the push plate 2 pushes the ore at the edge of the belt to the middle of the belt, avoiding the ore at the edge falling into the edge gap of the conveyor belt during transportation.

[0036] Reference Figure 4 and Figure 5 The cleaning assembly includes a cleaning brush 15, which is used to clean debris on the surface of the belt to avoid affecting the transmission efficiency of the conveyor belt 1. The side wall of the cleaning brush 15 is slidably connected to the inside of the conveyor belt 1, and a connecting hole 16 is opened inside the cleaning brush 15. The side wall of the conveyor belt 1 is fixedly connected to a fixing plate 17, and a clamping column 18 is slidably connected inside the fixing plate 17. The clamping column 18 is used to fix the cleaning brush 15, and the side wall of the clamping column 18 is slidably connected to the inside of the connecting hole 16. The side wall of the clamping column 18 is fixedly connected to a pull ring 19, and the side wall of the clamping column 18 is provided with a second spring 20. The second spring 20 is used for rebound reset. One end of the second spring 20 is fixedly connected to the side wall of the fixing plate 17, and the other end of the second spring 20 is fixedly connected to the side wall of the pull ring 19. The side wall of the conveyor belt 1 is fixedly connected to a hook 21. A collection box 22 is provided on the lower surface of the conveyor belt 1. The collection box 22 is used to collect the cleaned debris. The side wall of the collection box 22 is fixedly connected to a hanging ring 23, and the hanging ring 23 is slidably connected to the side wall of the hook 21;

[0037] By pulling the pull ring 19, the connected clamping column 18 moves accordingly. During the movement, the clamping column 18 squeezes the second spring 20 to make it contract. This contraction stores elastic potential energy and provides power for the subsequent fixation of the cleaning brush 15. The cleaning brush 15 is then inserted into the conveyor belt 1 so that the bristles of the cleaning brush 15 can fully contact the surface of the conveyor belt 1. When the cleaning brush 15 is inserted into the appropriate position so that the clamping column 18 is aligned with the connecting hole 16, the pull ring 19 is released. At this time, the second spring 20 is no longer squeezed and begins to rebound. During the rebound process, the second spring 20 pushes the clamping column 18 so that the clamping column 18 is accurately stuck in the connecting hole 16, thus completing the fixation of the cleaning brush 15. During the transportation of the conveyor belt 1, the cleaning brush 15 begins to play a role. Since some debris will remain on the surface of the conveyor belt 1 after long-term use, this If these debris are not cleaned in time, the friction between the conveyor belt 1 and the ore or other transported items will increase, and they may accumulate in certain parts of the conveyor belt 1, resulting in an uneven surface of the conveyor belt 1. The cleaning brush 15 can effectively remove these debris by contacting the surface of the conveyor belt 1, thereby avoiding affecting the transmission efficiency of the conveyor belt 1 due to the accumulation of debris. In the process of cleaning the debris with the cleaning brush 15, the debris will fall under the action of the cleaning brush 15, and the collection box 22 is located in a suitable position to catch these fallen debris. The collection box 22 is hung inside the hook 21 through the hanging ring 23. The cooperation of the hanging ring 23 and the hook 21 realizes the stable suspension of the collection box 22, so that the collection box 22 can accurately catch the debris cleaned from the conveyor belt 1, keep the working area clean, and facilitate subsequent centralized processing of the debris.

[0038] Working principle: During transportation, the conveyor belt 1 generates a large amount of dust due to collisions between ores, and a protective cover 6 needs to be installed to control the dust. During the movement of the protective cover 6, the block 9 is squeezed into the limit block 8. When the protective cover 6 moves to the top of the recessed hole 7, the first spring 10 loses its extrusion and the block 9 is clamped into the recessed hole 7 to fix the protective cover 6. Then the mounting bolt 11 is twisted into the protective cover 6 to fix it. At the same time, the fixing column 12 is clamped into the fixing hole 13 to connect the protective covers 6 on both sides. Then the fixing bolt 14 is twisted in to fix it. When the conveyor belt 1 is in use, the hydraulic rod 5 is started to push the push plate 2 to push the ore at the edge of the belt to the middle of the belt to avoid the ore at the edge falling into the edge gap of the conveyor belt during transportation.

[0039] By pulling the pull ring 19 to move the clamping column 18, the clamping column 18 squeezes the second spring 20 to shrink it, and then the cleaning brush 15 is inserted into the conveyor belt 1. After aligning the clamping column 18 with the connecting hole 16, the pull ring 19 is released, and the second spring 20 rebounds to clamp the clamping column 18 into the connecting hole 16 to fix the cleaning brush 15. During the transportation of the conveyor belt 1, the surface debris is cleaned to avoid affecting the transmission efficiency of the conveyor belt 1. The cleaned debris falls into the collection box 22, and the collection box 22 is hung on the hook 21 through the hanging ring 23 to catch the fallen debris.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
