Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, and in particular to a tear-resistant reinforcement structure for mining conveyor belts. Background Technology

[0002] In the mining and transportation of mineral resources such as coal and ore, mining conveyor belts, as key large-scale material conveying equipment, undertake the important task of continuously and efficiently transporting materials from underground or open-pit mines to designated locations. The working environment of conveyor belt systems is typically very harsh, with high dust concentrations and humidity, and they often need to transport large, sharp materials, and may even encounter impacts from accidentally falling heavy objects. These factors expose conveyor belts to severe risks of wear, punctures, and tears.

[0003] Some existing physical protection structures are effective in dealing with single types of impacts or punctures, but they are often complex in structure, inconvenient to maintain, or not comprehensive enough in terms of protection. They perform poorly when they need to resist both punctures by sharp objects and compression by large-area heavy objects. In addition, some structures interfere with the normal operation of the conveyor belt or are prone to failure after long-term use.

[0004] To address the above problems, it is necessary to design a tear-resistant reinforced structure for mining conveyor belts to overcome these issues. Utility Model Content

[0005] The main purpose of this utility model is to provide a tear-resistant and reinforced structure for mining conveyor belts, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A tear-resistant reinforcement structure for a mining conveyor belt includes a conveyor belt and a puncture-resistant pad. Rollers are installed at both ends of the inner side of the puncture-resistant pad, and a rotating shaft is connected to both ends of each roller. A limiting plate is connected to the end of each of the two rotating shafts away from the rollers. Multiple protective strips are connected to the outer wall of the conveyor belt.

A guide frame is connected between two adjacent movable rods. A concave groove is formed at the bottom of the inner side of the guide frame. Guide rods are connected to both ends of the inner side of the guide frame. Limit blocks are connected to the outer walls of two guide rods. A wheel is connected to the end of each limiting block away from the guide rod via a movable shaft. A limiting frame is connected to the outer wall of the wheel. A second telescopic rod is connected to the inner side of the two guide rods, and a spring is connected to the outer wall of the second telescopic rod.

[0009] As a preferred embodiment of this utility model, both ends of the inner side of the anti-puncture pad are in contact with the outer wall of the rotating roller, the rotating roller is rotatably connected to the rotating shaft, the rotating shaft is rotatably connected to the limiting plate, and the limiting plate is fixedly connected to the guide plate.

[0010] In a preferred embodiment of this utility model, the guide plate is rotatably connected to the movable rod, the movable rod is rotatably connected to the guide frame, the guide frame is rotatably connected to the two guide rods, the second telescopic rod is slidably connected to the inner side of the guide rod, and the second telescopic rod is fixedly connected to the spring.

[0014] Beneficial effects

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This mine conveyor belt anti-tear reinforcement structure uses rotating rollers and shafts to drive the conveyor belt to rotate. Protective strips on the outer wall of the conveyor belt reinforce it. Movable rods and guide frames are fixed to both ends of two guide plates. A limiting frame uses a movable shaft to limit the rotation of the wheel. A limiting spring at the top of the first telescopic rod is compressed downwards by the anti-puncture pad, causing the wheel to move up and down within the sleeve. This applies pressure to the wheel and then contacts the inner side of the anti-puncture pad, effectively preventing tearing of the conveyor belt and anti-puncture pad. The limiting frame uses limiting rods to limit the use of the limiting spring. Two guide rods on the inner side of the guide frame can move up and down within the guide frame after the second telescopic rod is compressed by the downward pressure of the anti-puncture pad, causing the guide rods and the limiting blocks on the outer wall to move up and down. This effectively prevents the conveyor belt and anti-puncture pad from tearing when subjected to heavy pressure, providing effective protection. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-5As shown, a tear-resistant reinforcement structure for a mining conveyor belt includes a conveyor belt 1 and a puncture-resistant pad 2. Rollers 3 are installed at both ends of the inner side of the puncture-resistant pad 2. A rotating shaft 4 is connected to both ends of the roller 3. A limiting plate 6 is connected to the end of each rotating shaft 4 away from the roller 3. Multiple protective strips 5 are connected to the outer wall of the conveyor belt 1. A guide plate 7 is connected between two adjacent limiting plates 6. Multiple movable rods 8 are connected to the inner side of each guide plate 7. A guide frame 9 is connected between two adjacent movable rods 8. A concave groove 10 is opened at the bottom of the inner side of the guide frame 9. Guide rods 14 are connected to both ends of the inner side of the guide frame 9. Limiting blocks 13 are connected to the outer walls of the two guide rods 14. A rotating wheel 12 is connected to the end of each limiting block 13 away from the guide rod 14 via a movable shaft. A limiting frame 11 is connected to the outer wall of the rotating wheel 12. A second telescopic rod 20 is connected to the inner side of the two guide rods 14. A spring 21 is connected to the outer wall of the second telescopic rod 20.

[0025] The inner sides of the anti-stab pad 2 are in contact with the outer walls of the rollers 3 at both ends. The rollers 3 are rotatably connected to the shaft 4. The shaft 4 is rotatably connected to the limiting plate 6. The limiting plate 6 is fixedly connected to the guide plate 7. The guide plate 7 is rotatably connected to the movable rod 8. The movable rod 8 is rotatably connected to the guide frame 9. The guide frame 9 is rotatably connected to the two guide rods 14. The second telescopic rod 20 is slidably connected to the inner side of the guide rod 14. The second telescopic rod 20 is fixedly connected to the spring 21. The top of the second telescopic rod 20 penetrates through the top of the anti-stab pad 2 and contacts the bottom of the conveyor belt 1. The limiting blocks 13 are all sleeved on the outer walls of the guide rods 14. The guide rods 14 are rotatably connected to the rotating wheel 12 through the movable shaft. The limiting frame 11 is sleeved on the outer walls of the movable shafts connected at both ends of the rotating wheel 12.

[0026] Specifically, the anti-puncture pad 2 is closely attached to the inner side of the conveyor belt 1 and moves synchronously with the conveyor belt. The anti-stab pad 2 itself has a certain thickness and strength, serving as the first physical barrier. The protective strip 5 installed on the outer wall of the conveyor belt 1 reinforces the main body of the conveyor belt, enhancing its overall strength and resistance to deformation. The guide frame 9 is supported by the movable rod 8 and the guide plate 7. The limiting block 13 is in the normal position within the guide frame 9. The spring 21 at the top of the second telescopic rod 20 is in a natural or slightly compressed state. The positions of the guide rod 14 and the limiting block 13 are relatively fixed. Under the restriction of the limiting block 13, the top of the wheel 12 is supported by the limiting spring 16 through the sleeve 15 and the limiting rod 19, and is in a preset initial position, contacting or maintaining a small gap with the inner side of the anti-stab pad 2. The top of the first telescopic rod 18 contacts the bottom of the anti-stab pad 2, and the limiting spring 16 is in a slightly pre-tightened state. When the conveyor belt 1 or the anti-stab pad 2 encounters sharp objects such as the edges of large pieces of ore or metal fragments, the sharp objects must first penetrate the anti-stab pad 2. The thickness and material properties of the anti-stab pad 2 provide the first layer of resistance.

[0027] A sleeve 15 is connected to the top of the rotating wheel 12. A limit spring 16 is connected to the inner side of the sleeve 15. A limit rod 19 is connected to the top of the limit spring 16. A limit frame 17 is fixedly installed on the top of the limit frame 11. A first telescopic rod 18 is connected to both ends of the top of the limit frame 17.

[0028] The limiting frame 17 is rotatably connected to both ends of the driving limiting rod 19. The limiting rod 19 is fixedly connected to the limiting spring 16. The limiting spring 16 is fixedly connected to the sleeve 15. The sleeve 15 is rotatably connected to the top of the rotating wheel 12. The two limiting rods 19 are slidably connected on the inner side of the limiting frame 17. The top of the first telescopic rod 18 contacts the bottom of the anti-stab pad 2.

[0029] Specifically, if the sharp object is sharp enough and has sufficient force, it will continue to penetrate downwards, directly impacting the inner surface of the anti-puncture pad 2 and attempting to further damage the conveyor belt 1. At this point, the top of the wheel 12 receives downward pressure from the anti-puncture pad 2 through the sleeve 15 and the limiting rod 19. This pressure acts on the limiting spring 16, causing it to compress and deform within the sleeve 15, thus moving the sleeve 15 and the wheel 12 downwards as a whole. The limiting frame 17 and the limiting rod 19 limit the compression stroke of the limiting spring 16, preventing excessive compression. After moving downwards, the outer edge of the roller 12 will make closer contact with the inner side of the anti-stab pad 2, and even generate a certain pressure. This will disperse the localized stress transmitted by the sharp object to a certain area of ​​the inner side of the anti-stab pad 2 through the arc-shaped surface of the roller 12. The friction and support force generated by the contact between the roller 12 and the inner side of the anti-stab pad 2 will increase the difficulty for the sharp object to continue to penetrate downwards. This will guide the deformation direction of the anti-stab pad 2 to a certain extent, making it more uniformly compressed rather than locally torn. This will effectively prevent or slow down the penetrating damage of the sharp object to the anti-stab pad 2 and the conveyor belt 1, and prevent tearing.

[0030] It should be noted that this utility model is a tear-resistant reinforcement structure for a mining conveyor belt. During use, the conveyor belt 1 runs smoothly under the drive of the rotating roller 3 and the rotating shaft 4, used to carry and transport materials. When a large heavy object accidentally falls or presses on the conveyor belt 1 and the anti-stab pad 2, a large area of ​​downward pressure is generated. This pressure is first borne by the conveyor belt 1 and the anti-stab pad 2 and transmitted downwards. The pressure is then transmitted through the anti-stab pad 2 to the top of the second telescopic rod 20. The second telescopic rod 20 moves downwards on the inner side of the guide rod 14, simultaneously compressing the spring 21 on its outer wall. The compression of the spring 21 provides a buffering force and drives the guide rod 14 and its outer wall limiting block 13 to move downwards on the inner side of the guide frame 9. As the limiting block 13 moves downwards, the constraint that originally limited the axis of the rotating wheel 12 is released or weakened. Under the pressure of the heavy object, the axis of the rotating wheel 12 can rotate or displace around the movable shaft on the guide rod 14 to a certain extent. Simultaneously, the pressure of the heavy object... It also acts directly on the inner side of the anti-stab pad 2, further pushing the roller 12 to move downward. When the roller 12 moves downward, it will also compress the limiting spring 16 at its top, causing it to rise and fall within the sleeve 15, and finally contact the inner side of the anti-stab pad 2, applying pressure. At this time, the roller 12 not only plays the role of dispersing stress and increasing resistance, but more importantly, it acts as a movable support point, allowing the anti-stab pad 2 and the conveyor belt 1 to undergo certain local compression and deformation when subjected to heavy pressure, rather than being directly crushed or torn. The downward movement of the limiting block 13 and the corresponding adjustment of the roller 12 ensure that even under heavy pressure, the roller 12 can effectively maintain contact with the inner side of the anti-stab pad 2 and provide support. Through the compression buffer of the spring 21 and the support reaction force of the limiting spring 16 of the double buffer and support mechanism, the huge pressure generated by the compression of heavy objects is effectively absorbed and dispersed, preventing the conveyor belt 1 and the anti-stab pad 2 from tearing due to excessive deformation or being crushed.

[0031] When the sharp object is removed or the heavy object is moved away, the downward pressure on the anti-stab pad 2 disappears, the limiting spring 16 returns to its original state under its own elastic force, pushes the rotating wheel 12 back to the initial position, and the second telescopic rod 20 resets under the elastic force of the spring 21, driving the guide rod 14 and the limiting block 13 back to the normal position, and re-limiting the axis of the rotating wheel 12.
