Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, specifically a heavy-duty conveyor chain. Background Technology

[0002] In many production processes of modern industry, such as cargo handling in large logistics and warehousing centers, ore transportation in mining, and raw material and finished product conveying in steel smelting, heavy-duty conveyor chains undertake critical material transportation tasks. Traditional heavy-duty conveyor chains have a relatively simple structural design, usually consisting of chain plates, pins, and connecting components. However, in the long-term actual operation, this traditional structure has revealed many problems.

[0003] On the one hand, traditional chains have poor transmission stability when faced with heavy loads or load shifts. Due to the lack of effective positioning and adaptive adjustment structures, the chains are prone to derailment or tooth skipping. This can not only lead to material conveying interruptions and affect the continuity of the production process, but may also cause equipment failure and safety accidents in severe cases.

[0004] On the other hand, traditional chains and sprockets mainly rely on sliding friction to achieve transmission. Under heavy load conditions, the huge friction not only significantly reduces transmission efficiency and leads to a sharp increase in energy consumption, but also generates a lot of heat, accelerating the wear of the chain and sprockets, shortening the overall service life of the equipment. Furthermore, once a component of a traditional heavy-duty conveyor chain is damaged after wear, the entire chain link often needs to be replaced, resulting in high maintenance costs and long maintenance time.

[0016] 1. This heavy-duty conveyor chain, through the rotatable engagement of the positioning shaft and the sleeve, can reduce transmission resistance and energy consumption when the sprocket drives the device by utilizing the rolling friction design of the support ring and guide ring. At the same time, the mutual cooperation of the support ring and guide ring can form a protective layer on the outside of the sleeve. Therefore, when friction occurs between the sleeve and the sprocket, the support ring will be worn first.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 5 This utility model embodiment provides a chain for use in conveying equipment under heavy loads. This embodiment improves the chain structure to achieve advantages such as stable conveying, high stability, and low maintenance costs. Specifically, taking the operation and maintenance of a heavy-duty chain as an example, as a preferred solution in this embodiment, the chain is specifically a heavy-duty conveyor chain, capable of adaptively adjusting the drive position of the sprocket under heavy loads and facilitating modular replacement after component wear.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a heavy-duty conveyor chain, which is applied to conveyor equipment under heavy load conditions.

[0027] The system includes a positioning frame 1, with a support plate 2 detachably connected to its top. The positioning frame 1 serves as the foundational support structure for the entire heavy-duty conveyor chain, connecting other key components and providing load-bearing and positioning functions. It ensures the relative positions of each part of the chain are fixed in space, providing a support framework for stable chain operation and guaranteeing the coordinated work of other components. The support plate 2 is detachably connected to the top of the positioning frame 1 and can be used to carry the conveyed materials or cooperate with other parts of the conveying system, providing a platform for placing materials or docking with other components. The detachable design facilitates individual maintenance, replacement, or adjustment to a more suitable size when needed, facilitating transmission and conveying operations. Guide blocks 3 are fixedly connected to both sides of the top of the support plate 2. The bottom of the support plate 2 is provided with guide grooves 4. The guide blocks 3 are fixed to the top of the positioning frame 1 on both sides. The guide grooves 4 are provided at the bottom of the support plate 2. The two are slidably connected, which makes it easy to install or remove the support plate 2, and facilitates the disassembly and replacement by the staff. The inner wall of the guide groove 4 is slidably connected to the outer surface of the guide block 3. The outer surface of the support plate 2 is detachably connected with a pad 5. The outer surface of the pad 5 is provided with anti-slip texture. The pad 5 can form protection on the outside of the support plate 2. The anti-slip texture on its outer surface is used to increase the friction between the support plate 2 and the material it carries, and prevent the material from sliding during the conveying process.

[0028] A positioning shaft 6 is inserted into one side of the bottom of the positioning frame 1. Four main connecting pieces 7 and three auxiliary connecting pieces 8 are sleeved on the outer surface of the positioning shaft 6. These four main connecting pieces 7 and three auxiliary connecting pieces 8 respectively engage with the outer surfaces of the adjacent positioning shafts 6 on both sides. The positioning shaft 6 is inserted into one side of the bottom of the positioning frame 1, and its outer surface is sleeved with the main connecting pieces 7 and auxiliary connecting pieces 8. It also rotatably connects two sleeves 9. The positioning shaft 6 serves to connect and support other rotating components, and is also one of the key components for power transmission. Through cooperation with other components, it transmits the rotation of the sprocket to the sleeves 9, thereby driving the entire... As the chain runs, its stable support structure ensures the stability of components such as the sleeve 9 during rotation, reducing swaying and offset. Four main connecting pieces 7 and three auxiliary connecting pieces 8 are sleeved on the outer surface of the positioning shaft 6. The main connecting pieces 7 and auxiliary connecting pieces 8 are used to connect the positioning shaft 6 to other components, such as connecting the sleeve 9 to the positioning shaft 6. In the overall structure of the chain, they also play a role in distributing force and enhancing connection stability, making the connection between various parts of the chain more robust. When bearing heavy loads, the force can be evenly distributed, avoiding excessive local force that could damage components and extending the service life of the chain.

[0029] Two sleeves 9 are rotatably connected to the outer surface of the positioning shaft 6. The sleeves 9 are rotatably connected between two auxiliary connecting pieces 8. A washer 10, multiple support rings 11, and guide rings 12 on both sides are fitted onto the outer surface of the sleeve 9. The sleeve 9 rotates on the positioning shaft 6 and provides a mounting base for the support rings 11 and guide rings 12. It is also one of the key components for the chain to contact the sprocket and transmit power. Through its rotatable engagement with the positioning shaft 6, it converts the rotation of the sprocket into the movement of the chain. The smoothness of its rotation directly affects the chain's transmission efficiency. Meanwhile, the support rings 11 and guide rings 12 are mounted on its outer surface, protecting the sleeve 9 and ensuring better engagement with the sprocket. The two sleeves 9 are rotatably connected between two auxiliary connecting pieces 8. Between the auxiliary connecting pieces 8, washers 10 are fitted onto the outer surfaces of the two sleeves 9. The washers 10 are fitted onto the outer surfaces of the sleeves 9, and their outer surfaces are respectively inserted into the inner walls of the multiple support rings 11 and the two guide rings 12. The washers 10 play a buffering and positioning role, ensuring the synchronization of the support rings 11 and guide rings 12 when they rotate with the sleeves 9, and at the same time ensuring that the positions of the support rings 11 and guide rings 12 on the sleeves 9 are fixed, reducing the wear caused by the multiple sleeves 9, extending the service life of these components, and ensuring their relative position stability during operation, thereby better playing the supporting and guiding role. The outer surfaces of the washers 10 are respectively inserted into the inner walls of the multiple support rings 11 and the two guide rings 12.

[0030] Multiple support rings 11 are fitted onto the outer surface of the sleeve 9. When the sprocket drives the chain, the support rings 11 use rolling friction design to contact the sprocket, which plays a role in supporting the chain and reducing transmission resistance. At the same time, when friction occurs between the sleeve 9 and the sprocket, the support rings 11 are worn first, protecting the sleeve 9. This greatly reduces the frictional resistance between the chain and the sprocket, reduces energy consumption, and improves transmission efficiency. Its wear-resistant design can also extend the overall service life of the chain to a certain extent, and helps to maintain the stable operation of the chain under heavy load or load deviation. Guide rings 12 are fitted onto both sides of the outer surface of the sleeve 9, which is located on the outer surface of the sleeve 9. The guide rings 12, with their inclined shape, center the relative position between the sprocket and the chain during chain operation. When the chain is under heavy load or the load shifts, the guide rings 12 can stabilize the chain position, prevent chain slippage or tooth skipping, significantly improve the stability and safety of the chain under various working conditions, effectively avoid chain slippage or tooth skipping, ensure the continuity of material conveying, and reduce production interruptions and safety accidents caused by chain failure. Limiting grooves 13 are provided on both sides of the outer surface of the positioning shaft 6. Limiting rings 14 are engaged with the inner sidewalls of the limiting grooves 13. The limiting grooves 13 are provided on both sides of the outer surface of the positioning shaft 6, and the limiting rings 14 are engaged with the inner sidewalls of the limiting grooves 13. Together, they restrict the axial movement of components such as the sleeve 9 on the positioning shaft 6, prevent the components from falling off the positioning shaft 6, ensure that the position of each component of the chain is fixed during operation, improve the stability of the entire chain structure, avoid chain failure caused by axial movement of components, and ensure the normal operation of the chain.

[0031] In this invention, the working steps of the device are as follows:

[0032] 1. First, fix the positioning frame 1 as the basic support structure. Then, detachably install the support plate 2 on the top of the positioning frame 1 through the cooperation of the guide block 3 and the guide groove 4. Install the pad 5 with anti-slip texture on the outer surface of the support plate 2 to prevent the material from sliding. Insert the positioning shaft 6 into one side of the bottom of the positioning frame 1. Fit the four main connecting pieces 7 and the three auxiliary connecting pieces 8 onto the outer surface of the positioning shaft 6. Next, rotatably connect the two sleeves 9 between the two auxiliary connecting pieces 8. Then, fit the washer 10, multiple support rings 11 and the guide rings 12 on both sides onto the outer surface of the sleeve 9 in sequence. Finally, snap the limiting ring 14 into the limiting groove 13 on both sides of the outer surface of the positioning shaft 6 to complete the chain assembly.

[0033] 2. When the sprocket is running, it contacts the chain and applies driving force. The positioning shaft 6 transmits the rotation of the sprocket to the rotatably connected sleeve 9. Since the support ring 11 sleeved on the outer surface of the sleeve 9 adopts a rolling friction design and contacts the sprocket, the support ring 11 rolls, driving the sleeve 9 and the entire chain to move, realizing the transmission of power from the sprocket to the chain. At the same time, this rolling friction greatly reduces the transmission resistance and reduces energy consumption.

[0034] 3. During chain operation, when encountering heavy loads or load deviations, the guide rings 12 located on both sides of the outer surface of the sleeve 9 guide the transmission position of the sprocket by their own inclined shape, ensuring that the relative position between the sprocket and the chain is centered and adjusted, effectively preventing the chain from derailing or skipping teeth, and ensuring the stability and safety of chain operation. At the same time, the support ring 11 wears preferentially when friction occurs between the sleeve 9 and the sprocket, protecting the sleeve 9, extending the service life of the sleeve 9, and further ensuring the stable operation of the chain.

[0035] 4. When the chain is used for a long time and some parts are damaged, the positioning shaft 6 can be disassembled first, and then the sleeve 9, support ring 11 and guide ring 12 can be disassembled to replace the damaged parts individually. Since the support ring 11 and guide ring 12 adopt a modular design, they can be made of materials with higher hardness, which reduces manufacturing and replacement costs and improves wear resistance.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
