A support structure for a plate chain

Abstract

This utility model discloses a support structure for a plate chain, including a support frame. A set of rotating rods is rotatably mounted through both ends of the inner side of the support frame. A drive wheel is fixedly fitted in the middle of the two sets of rotating rods. A plate chain for conveying is mounted on the outer sides of the four sets of drive wheels through a common transmission engagement. An adjustment component for controlling the tension of the plate chain is installed inside the support frame. By adjusting the tension of the plate chain, when the tension is reduced, an electric actuator drives a moving plate downwards. Simultaneously, the moving plate moves downwards, driving auxiliary gears downwards via a rotating seat. The two sets of auxiliary gears press the lower plate chain downwards, increasing the overall tension of the plate chain. Similarly, activating the electric actuator indirectly controls the upward movement of the two sets of auxiliary gears, reducing the tension of the plate chain. This achieves the effect of quickly adjusting the tension of the plate chain, making operation simple and quick, and improving the efficiency of the plate chain.

Description

Technical Field

[0001] This utility model relates to the field of irradiated cargo technology, specifically to a support structure for a plate chain. Background Technology

[0002] Plate chains are a core component in the field of chain transmission and conveying, and belong to an important branch of transmission chains / conveying chains. Essentially, they are flexible components composed of several standardized "chain link units" hinged together. Their core function is to transmit power, torque or convey materials between the driving sprocket and the driven sprocket (or conveying track). They are widely used in mechanical transmission and material handling scenarios under low-speed, heavy-load, and harsh working conditions. This utility model is aimed at material handling scenarios using plate chains.

[0003] Existing plate chains form a conveyor chain through a support frame and internal drive components. Activating the drive components moves the plate chain to achieve material transfer. To prevent the upper plate chain from sagging under the weight of the material and causing tilting during material transport, support components are generally used to lift the plate chain, keeping it in a relatively horizontal state. However, as the various link units of the plate chain wear down, the length of the plate chain changes, resulting in a decrease in the tension of the plate chain. This exacerbates the sagging of the plate chain and affects the accuracy of material transport. Increasing the tension by shortening the length of the plate chain or adjusting the distance between the two sets of rotating rods is too cumbersome. Therefore, we need to propose a support structure for plate chains. Utility Model Content

[0004] The purpose of this invention is to provide a support structure for a plate chain. Through the connection between the support frame, rotating rod, drive wheel, and plate chain, the main structure of the plate chain conveyor is installed. Rotating the rotating rod drives the drive wheel to rotate, indirectly driving the plate chain to move in a cycle. When the tension of the plate chain decreases, by adjusting the components and utilizing the connection between the mounting plate, fixed plate, electric push rod, moving plate, rotating seat, and auxiliary gears, the electric push rod is activated to move the moving plate downward. As the moving plate moves downward, the auxiliary gears move downward through the rotating seat. The two sets of auxiliary gears press the lower plate chain downward, thereby quickly increasing the tension of the plate chain. Furthermore, the auxiliary gears can move stably inside the rotating seat and follow the movement of the plate chain without affecting the normal operation of the plate chain, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support structure for a plate chain, comprising a support frame, with a set of rotating rods rotatably mounted through both ends of the inner side of the support frame, a drive wheel fixedly fitted in the middle of the two sets of rotating rods, and a set of plate chains for conveying connected to the outer sides of the four sets of drive wheels through common transmission engagement; an adjustment component for controlling the tension of the plate chain is installed on the inner side of the support frame, and a support component for supporting the upper plate chain is installed on the top of the adjustment component; the adjustment component includes two sets of mounting plates fixedly mounted in a support manner on the inner side of the support frame, a fixed plate fixedly mounted in the middle of the opposite sides of the two sets of mounting plates, an electric actuator bolted to the top of the fixed plate, a movable plate connected to the output end of the electric actuator, and two sets of auxiliary gears rotatably mounted on the bottom of the movable plate through two sets of rotating seats, the two sets of auxiliary gears engaging and transmitting with the lower plate chain.

[0006] Preferably, the plate chain includes two sets of chains mounted on the outside of two sets of drive wheels in a bracing transmission manner, and several sets of transmission plates are fixedly mounted on the opposite sides of the two sets of chains.

[0007] Preferably, the support assembly includes two sets of support plates, with the tops of the two sets of support plates respectively mounted on the top of one set of support plates, and several sets of idlers are rotatably mounted on the inner sides of the two sets of support plates.

[0008] Preferably, the tops of several sets of idlers are in active contact with the upper chain, and the auxiliary gears are respectively engaged with a set of lower chains.

[0009] Preferably, each of the two sets of mounting plates has a set of sliding grooves on opposite sides, and each of the two ends of the movable plate has a set of sliders fixedly installed, with the two sets of sliders slidably installed inside the set of sliding grooves respectively.

[0010] Preferably, a set of sliding rods is fixedly installed on the inner side of each of the two sets of sliding grooves, and the two sets of sliders are respectively slidably fitted onto the outer arc surface of the sliding rods.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention, through the adjustment of the component settings, allows for the downward movement of a movable plate by activating an electric actuator when the tension of the chain decreases. Simultaneously, the movable plate moves downward via a rotating seat, causing auxiliary gears to move downward. These two sets of auxiliary gears press down on the lower chain, increasing the overall tension of the chain. Similarly, activating the electric actuator indirectly controls the upward movement of the two sets of auxiliary gears, reducing the chain tension. This achieves rapid adjustment of the chain tension, making operation simple and quick, and improving the efficiency of the chain.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6This utility model provides a support structure for a plate chain, including a support frame 1. A set of rotating rods 2 are rotatably installed through both ends of the inner side of the support frame 1. A drive wheel 3 is fixedly mounted in the middle of the two sets of rotating rods 2. A set of plate chains 4 for conveying is installed on the outer side of the four sets of drive wheels 3 through common transmission and meshing. An adjustment component for controlling the tension of the plate chain 4 is installed on the inner side of the support frame 1. A support component for lifting the upper plate chain 4 is installed on the top of the adjustment component. The adjustment component includes two sets of mounting plates 5 fixedly installed in a support manner on the inner side of the support frame 1. A fixing plate 6 is fixedly installed in the middle of the opposite side of the two sets of mounting plates 5. An electric push rod 7 is bolted to the top of the fixing plate 6. A movable plate 8 is connected to the output end of the electric push rod 7. Two sets of auxiliary gears 10 are rotatably installed on the bottom of the movable plate 8 through two sets of rotating seats 9. The two sets of auxiliary gears 10 are meshed and transmitted with the lower plate chain 4.

[0023] In use, the main structure of the conveyor belt 4 is installed through the connection between the support frame 1, the rotating rod 2, the drive wheel 3, and the plate chain 4. An external drive motor (not shown in the figure) drives the rotating rod 2 to rotate, which in turn drives the drive wheel 3 to rotate, indirectly causing the plate chain 4 to move in a cycle. When the tension of the plate chain 4 decreases, the adjustment component is set to adjust the tension of the plate chain 4. When the tension of the plate chain 4 decreases, the electric push rod 7 is activated to drive the moving plate 8 to move downward. At the same time, the moving plate 8 moves downward, and the auxiliary gear 10 moves downward through the rotating seat 9. The two sets of auxiliary gears 10 press down on the lower plate chain 4, increasing the overall tension of the plate chain 4. Similarly, activating the electric push rod 7 indirectly controls the two sets of auxiliary gears 10 to move upward, which will reduce the tension of the plate chain 4. This achieves the effect of quickly adjusting the tension of the plate chain 4. Moreover, the auxiliary gears 10 can move with the plate chain 4 and rotate stably inside the rotating seat 9 without affecting the normal operation of the plate chain 4.

[0024] The plate chain 4 includes two sets of chains 41 mounted on the outside of two sets of drive wheels 3 with a support-type transmission. Several sets of conveyor plates 42 are fixedly installed on the opposite sides of the two sets of chains 41. The plate chain 4 is the core component of the conveying system, including two sets of parallel chains 41 and several sets of conveyor plates 42, which are fixed to the opposite sides of the two sets of chains 41 by bolts or welding. Adjacent conveyor plates 42 have a certain distance for flipping to form a continuous conveying surface for carrying materials, thereby achieving the effect of material conveying.

[0025] The support assembly includes two sets of support plates 11, with the tops of the two sets of support plates 11 respectively mounted on the top of one set of support plates 11. Several sets of idlers 12 are rotatably mounted on the inner sides of the two sets of support plates 11. The tops of the idlers 12 are in contact with the upper chain 41. When the upper chain 41 carries materials, its bottom contacts the idlers 12. The idlers 12 rotate synchronously with the chain 41, providing upward support to the chain 41, preventing the chain 41 from sagging, and ensuring a smooth material conveying process. At the same time, the rolling friction of the idlers 12 reduces the wear of the chain 41 and improves the service life of the chain 41. The auxiliary gears 10 are meshed with the lower set of chains 41 respectively. When the two sets of chains 41 rotate, they drive the auxiliary wheels to rotate. The auxiliary gears 10 control the tension of the chains 41 without affecting the normal operation of the chains 41.

[0026] Each of the two sets of mounting plates 5 has a set of sliding grooves 13 on opposite sides. A set of sliders 15 is fixedly installed at both ends of the movable plate 8, and the two sets of sliders 15 are slidably installed inside the sliding grooves 13. A set of sliding rods 14 is fixedly installed inside each of the two sets of sliding grooves 13. The two sets of sliders 15 are slidably fitted onto the outer arc surface of the sliding rods 14. When the movable plate 8 moves up and down, it drives the sliders 15 to slide directionally along the outer arc surface of the sliding rods 14. The two sets of sliders 15 are also limited by the sliding grooves 13, ensuring that the movable plate 8 remains horizontal during up and down movement. This prevents the movable plate 8 from shifting left or right or tilting during adjustment, improves the stability of the meshing installation of the auxiliary gear 10 and the chain 41, and avoids tooth stripping or uneven wear.

[0027] In practical use, the drive motor drives the rotating rod 2 to rotate through the coupling, and the drive wheel 3 rotates synchronously. The toothed surface of the drive wheel 4 drives the plate chain 4 to circulate. The upper conveyor plate 42 carries the material and moves along the conveying direction. When the upper chain 41 carries the material, its bottom contacts the idler roller 12. The idler roller 12 rotates synchronously with the chain 41, providing upward support for the chain 41 and preventing it from sagging. At the same time, the rolling friction of the idler roller 12 reduces the wear of the chain 41, ensuring a smooth conveying process. When the tension of the chain 41 needs to be adjusted, the electric actuator 7 is activated to extend and push the moving plate 8 down along the slide bar 14, indirectly driving the auxiliary gear 10 to press down. The upper chain 41 increases the tension of the chain 41. When the electric push rod 7 shortens, the moving plate 8 drives the auxiliary gear 10 to move upward, reducing the tension of the chain 41, thereby achieving the effect of quickly adjusting the tension of the chain 41. When the upper chain 41 carries materials, its bottom contacts the idler roller 12. The idler roller 12 moves synchronously with the chain 41, providing upward support for the chain 41 and preventing the chain 41 from sagging. At the same time, the rolling friction of the idler roller 12 reduces the wear of the chain 41, ensuring a smooth conveying process. It is worth noting that the chain 41 and the drive wheel 3 need to be protected with a protective shell to improve the stability and safety of transportation.

[0028] 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.
