Description

Technical Field

[0001] This utility model relates to the field of conveyor drive roller technology, specifically a high-performance drive roller for belt conveyors. Background Technology

[0002] With belt conveyors widely used in mining, metallurgy, and coal industries, the drive drum, as a key component, has a profound impact on the overall operating efficiency of the equipment due to the ease of its installation and disassembly. Especially in special working environments such as underground coal mines, belt conveyors undertake more than 90% of the transportation tasks. However, underground coal seams are thin and complex in distribution, and roadway space is limited by investment and coal seam conditions, so belt conveyors are often used in narrow spaces. Existing belt conveyor drive drums are usually secured to the conveyor frame by multiple sets of fasteners. Most belt conveyor drive drums are integrated designs, which makes it inconvenient to disassemble when replacement or maintenance is required, and the entire drum needs to be replaced, increasing costs and affecting the convenience of maintenance and repair.

[0003] According to the description in the patent announcement of a belt conveyor drive roller (authorization announcement number: CN210365595U), the belt conveyor drive roller includes "ring seat, reinforcing rod" etc. to realize the transmission work.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] The drive roller of this belt conveyor uses ring seats, reinforcing rods, etc. to achieve transmission. During use, the roller body, shaft and bearing housing are integrated into one unit. Therefore, when the roller body needs maintenance or replacement, it cannot be easily disassembled and the whole unit needs to be replaced. This not only increases the efficiency of maintenance and replacement but also increases the cost. Therefore, this roller needs to be improved. Utility Model Content

[0006] The purpose of this invention is to provide a high-performance drive roller for belt conveyors to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-performance drive roller for a belt conveyor, including a bearing housing, wherein an installation mechanism is provided inside the bearing housing;

[0008] The installation mechanism includes a rotating shaft rotatably connected to the inside of a bearing housing. A limiting disc is fixedly connected to the left side of the rotating shaft, and a roller body is disposed on the left side of the limiting disc. A limiting pin is threadedly connected inside the limiting disc. A threaded rod is rotatably connected inside the rotating shaft, and a moving block is threadedly connected to the outer periphery of the threaded rod. The moving block is slidably connected to the inside of the rotating shaft. A moving frame is fixedly connected to the top of the moving block. A limiting shaft is fixedly connected to the left side of the moving frame and inserted into the inside of the roller body. A connecting block is inserted into the inside of the threaded rod, and a rotating disc is fixedly connected to the right side of the connecting block.

[0009] Preferably, the left side of the limiting plate is in contact with the inner side of the roller body, and the left side of the limiting pin is threaded into the inside of the roller body, which facilitates the stability between the roller body and the limiting plate under the action of the limiting pin, and also facilitates installation and disassembly.

[0010] Preferably, the rotating shaft has a groove inside, and the moving block is slidably connected in the groove, which helps to ensure the stability of the moving block's movement under the action of the groove.

[0011] Preferably, there are two sets of the movable frame and the limiting shaft, which are symmetrically distributed on the upper and lower sides of the movable block. The two sets of the limiting shaft are respectively inserted into the inside of the roller body, which facilitates the improvement of the stability of the roller body by setting two sets.

[0012] Preferably, the bearing housing, rotating shaft, limiting plate, limiting pin, threaded rod, moving block, moving frame, limiting shaft, connecting block and rotating disk are provided in two sets. The two sets of bearing housing, rotating shaft, limiting plate, limiting pin, threaded rod, moving block, moving frame, limiting shaft, connecting block and rotating disk are symmetrically distributed on the left and right sides of the roller body. By setting two sets, the stability of the roller body can be further ensured, and the installation and disassembly can be facilitated.

[0013] Preferably, the roller body includes a high-temperature resistant layer, an anti-wear layer is fixedly connected to the periphery of the high-temperature resistant layer, a toughness layer is fixedly connected to the periphery of the anti-wear layer, and an anti-wear layer is fixedly connected to the periphery of the toughness layer.

[0014] Preferably, the high-temperature resistant layer is the innermost layer, which is made of fiber-reinforced composite material, and the wear-resistant layer is the outermost layer, which is made of ceramic material. Fiber-reinforced composite material has good high-temperature resistance and can maintain stable performance in high-temperature environments, preventing the roller from deforming, being damaged, or having its transmission efficiency affected due to excessive temperature. Ceramic has extremely high hardness and wear resistance, which can resist the wear of materials on the roller surface during the conveying process, greatly extending the service life of the roller.

[0015] Compared with the prior art, this utility model provides a high-performance drive roller for a belt conveyor, which has the following advantages:

[0016] 1. This high-performance drive roller of the belt conveyor features a specially designed installation mechanism. The rotating shaft is rotatably connected to the bearing housing. With the help of a limiting disc and limiting pin, the operation is simple during the initial positioning of the roller body. By rotating the rotating disc, the threaded rod is rotated, which in turn causes the moving block to slide within the rotating shaft. The connected moving frame and limiting shaft can be quickly and accurately inserted into the inside of the roller body to complete a stable connection. Compared with traditional installation methods, the installation time is significantly shortened. The limiting disc is in close contact with the inner side of the roller body, and the limiting pin is threaded through the limiting disc and connected to the inside of the roller body, providing the first layer of stability. Two sets of symmetrically distributed moving frames and limiting shafts further reinforce the connection between the rotating shaft and the roller body from the top and bottom, preventing relative displacement during operation. Once the fixing is complete, the connecting block and rotating disc can be removed. By connecting the external drive equipment to the rotating shaft, the roller body can be driven to work, facilitating installation and disassembly.

[0017] 2. This belt conveyor features a high-performance drive roller with multiple layers: a high-temperature resistant layer, an anti-wear layer, a toughness layer, and a wear-resistant layer. The innermost high-temperature resistant layer is made of fiber-reinforced composite material, effectively resisting damage to the roller from high-temperature environments and ensuring normal operation under high-temperature conditions. The outer anti-wear and wear-resistant layers, especially the outermost wear-resistant layer made of ceramic material, greatly improve the roller's wear resistance. Ceramics have extremely high hardness and wear resistance, resisting the wear of materials on the roller surface during conveying, significantly extending the roller's service life and reducing maintenance costs. The anti-wear layer is made of alloy structural steel, undergoing special alloying and heat treatment processes, resulting in excellent wear resistance and further improving the wear resistance of the roller surface, protecting the internal structure from wear. The toughness layer is made of high-strength alloy steel, which has good toughness and high strength, capable of withstanding the enormous stress and impact during transmission, preventing the roller from cracking or deforming during operation, and can withstand long-term repeated loads.

[0028] This utility model provides the following technical solution:

[0029] Example 1

[0030] Please see Figure 1-6 This utility model provides a technical solution: a high-performance transmission drum for a belt conveyor, including a bearing housing 1, and an installation mechanism 2 is provided inside the bearing housing 1;

[0031] The mounting mechanism 2 includes a rotating shaft 21, which is rotatably connected to the inside of the bearing housing 1. A limiting plate 22 is fixedly connected to the left side of the rotating shaft 21. A roller body 23 is provided on the left side of the limiting plate 22. A limiting pin 26 is threadedly connected inside the limiting plate 22. A threaded rod 24 is rotatably connected inside the rotating shaft 21. A moving block 25 is threadedly connected to the outside of the threaded rod 24. The moving block 25 is slidably connected to the inside of the rotating shaft 21. A moving frame 27 is fixedly connected to the top of the moving block 25. A limiting shaft 28 is fixedly connected to the left side of the moving frame 27. The limiting shaft 28 is inserted into the inside of the roller body 23. A connecting block 29 is inserted into the inside of the threaded rod 24. A rotating disk 291 is fixedly connected to the right side of the connecting block 29.

[0032] The left side of the limiting plate 22 is in contact with the inner side of the roller body 23. The left side of the limiting pin 26 is threaded into the inside of the roller body 23, which facilitates the stability between the roller body 23 and the limiting plate 22 under the action of the limiting pin 26, and also facilitates installation and disassembly. The rotating shaft 21 has a sliding groove inside, and the moving block 25 is slidably connected in the sliding groove, which facilitates the stability of the moving block 25 under the action of the sliding groove.

[0033] Two sets of movable frames 27 and limiting shafts 28 are provided, symmetrically distributed on the upper and lower sides of the movable block 25. The two sets of limiting shafts 28 are respectively inserted into the inside of the roller body 23. By setting two sets, the stability of fixing the roller body 23 can be improved. Two sets of bearing seats 1, rotating shafts 21, limiting discs 22, limiting pins 26, threaded rods 24, movable blocks 25, movable frames 27, limiting shafts 28, connecting blocks 29 and rotating disks 291 are provided, symmetrically distributed on the left and right sides of the roller body 23. By setting two sets, the stability of the roller body 23 can be further ensured, and installation and disassembly can be facilitated.

[0034] Example 2

[0035] Please see Figure 1-6 Furthermore, based on Embodiment 1, the roller body 23 further includes a high-temperature resistant layer 3, an anti-wear layer 4 fixedly connected to the periphery of the high-temperature resistant layer 3, a toughness layer 5 fixedly connected to the periphery of the anti-wear layer 4, and an anti-wear layer 6 fixedly connected to the periphery of the toughness layer 5. The high-temperature resistant layer 3 is the innermost layer and is made of fiber-reinforced composite material. The anti-wear layer 6 is the outermost layer and is made of ceramic material. The fiber-reinforced composite material has good high-temperature resistance and can maintain stable performance in high-temperature environments, preventing the roller from deforming, being damaged, or having its transmission efficiency affected due to excessive temperature. The ceramic has extremely high hardness and wear resistance, which can resist the wear of materials on the roller surface during the conveying process, greatly extending the service life of the roller.

[0036] In actual operation, when this device is used, firstly, the left side of the limiting plate 22 is brought into contact with the inner side of the roller body 23 and fixed by the limiting pin 26. The operation is simple when initially positioning the roller body 23. At the same time, the connecting block 29 is inserted into the threaded rod 24. Rotating the rotating plate 291 causes the rotating plate 291 to drive the threaded rod 24 to rotate, thereby causing the moving block 25 to slide in the rotating shaft 21. The connected moving frame 27 and limiting shaft 28 can be quickly and accurately inserted into the roller body 23 to complete a stable connection. Compared with the traditional installation method, the installation time is greatly shortened.

[0037] The limiting plate 22 is in close contact with the inner side of the roller body 23, and the limiting pin 26 is threaded through the limiting plate 22 and connected to the inside of the roller body 23, providing the first layer of stability. Two sets of symmetrically distributed moving frames 27 and limiting shafts 28 further reinforce the connection between the rotating shaft 21 and the roller body 23 from the top and bottom sides, preventing relative displacement during operation. When the fixing is completed, the connecting block 29 and the rotating plate 291 can be removed, and the bearing seat 1 can be slidably connected to a suitable position on the outer periphery of the rotating shaft 21. The positions of the bearing seats 1 on the left and right sides correspond to each other, and the bearing seats 1 are fixed by external fixing equipment to ensure the stability of the bearing seats 1.

[0038] Once fixed, the roller body 23 can be driven to work by connecting to the rotating shaft 21 on either the left or right side via an external drive device, which also facilitates installation and disassembly.

[0039] The innermost high-temperature resistant layer 3 is made of fiber-reinforced composite material, which can effectively resist the damage of high-temperature environment to the roller and ensure that the equipment can still operate normally under high-temperature conditions. The outer wear-resistant layer 4 and wear-resistant layer 6, especially the outermost wear-resistant layer 6 made of ceramic material, greatly improve the wear resistance of the roller. Ceramic has extremely high hardness and wear resistance, which can resist the wear of materials on the roller surface during the conveying process, greatly extend the service life of the roller, and reduce maintenance costs. The wear-resistant layer 4 is made of alloy structural steel material. After special alloying and heat treatment processes, it has good wear resistance and further improves the wear resistance of the roller surface, protecting the internal structure from wear. The toughness layer 5 is made of high-strength alloy steel material. High-strength alloy steel has good toughness and high strength, which can withstand the huge stress and impact during the transmission process, prevent the roller from cracking or deforming during operation, and can withstand long-term repeated loads.
