Description

Technical Field

[0001] This utility model relates to the field of chain tensioning technology for tubular chain conveyors, and in particular to a chain tensioning device for tubular chain conveyors that is easy to install. Background Technology

[0002] The chain tensioning device of a tubular chain conveyor is a key component used to adjust the tension between chain links and prevent chain slippage. Traditional chain conveyors often suffer from reduced transport efficiency or even accidents when handling high-viscosity, granular materials due to chain slack or slippage. The tensioning device ensures the smoothness and reliability of material transport by adjusting the chain tension.

[0003] In existing technologies, the chain tensioning device of tubular chain conveyors is difficult to adjust precisely due to its complex adjustment structure and lack of a precise control mechanism. This inadequacy is mainly because existing designs often only consider the optimization of a single factor, failing to fully account for the influence of material characteristics, environmental conditions, and equipment operating status on chain tension. In addition, traditional adjustment methods usually rely on frequent manual operation, which is not only inefficient but may also cause chain link slack or slippage, directly affecting the stability and reliability of the conveying system. This problem is particularly evident when handling high-viscosity or granular materials, which may lead to a significant decrease in transportation efficiency or even system failure, seriously threatening the safety of equipment operators and the stability of the production environment.

[0004] In response to this technical problem, this application proposes an easy-to-install chain tensioning device for tubular chain conveyors. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an easy-to-install chain tensioning device for tubular chain conveyors. This device is easy to install, enhances the practicality and reliability of the device, ensures efficient and stable operation of the conveyor, reduces maintenance needs, lowers the difficulty of operation, and provides great convenience for equipment maintenance and upkeep.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A chain tensioning device for a tubular chain conveyor that is easy to install includes a worktable. A drive motor is fixedly connected to the left side of the top of the worktable, and a transmission shaft is rotatably connected to the right side of the top of the worktable. A sprocket is fixedly connected to both the front end of the transmission shaft and the driving end of the drive motor. The outer diameter of the sprocket is connected through the inner side of the transmission chain. A connecting platform is connected to the inner wall of the top of the worktable through an installation assembly. A fixed shell is fixedly connected to the top of the connecting platform. A connecting frame is slidably connected to the inner wall of the fixed shell. A toothed plate is connected to the front end of the connecting frame through a tensioning assembly.

[0007] Furthermore, the mounting assembly includes a fixing frame that is fixedly connected to both the left and right ends of the top of the connecting platform, and a pressing plate is slidably connected to the inner wall of the fixing frame.

[0008] Furthermore, both ends of the pressing plate are rotatably connected to traction plates, and the opposite end of the traction plate is rotatably connected to a locking rod.

[0009] Furthermore, the workbench has matching grooves on both the front and rear sides of the inner wall at the top, and the opposite end of the traction plate is detachably connected to the inner wall of the matching groove. The top of the pressing plate is fixedly connected to a return spring, and the top of the return spring is fixedly connected to the top of the inner wall of the fixing frame.

[0010] Furthermore, the mounting assembly includes a bearing shaft rotatably connected to the inner wall of the connecting frame, a cross is fixedly connected to the rear end of the outer wall of the bearing shaft, and a sliding sleeve is slidably connected to the front end of the outer wall of the bearing shaft.

[0011] Furthermore, a rotating rod is rotatably connected to the front end of the sliding sleeve, and the rear end of the rotating rod is threadedly connected to the inner wall of the bearing shaft.

[0012] Furthermore, the outer walls of the front and rear ends of the sliding sleeve are rotatably connected to four sides of the outer wall, and the opposite ends of the support plates are rotatably connected to support frames. The rear end of the support frame is slidably connected to the inner wall of the cross, and the opposite ends of the toothed plates are respectively fixedly connected to the opposite ends of the support frames.

[0013] Furthermore, a transmission screw is rotatably connected to the inner wall of the fixed shell, and the bottom end of the connecting frame is rotatably connected to the outer wall of the transmission screw.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the rotating rod moves along the sliding sleeve tube, causing the support frame and toothed plate to expand outward, ensuring that the inner side of the transmission chain maintains appropriate tension, avoiding loosening that affects the conveying efficiency. The bearing shaft can rotate to ensure smooth chain transmission.

[0018] 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.

[0019] Reference Figure 1-3 This utility model provides an embodiment of a chain tensioning device for a tubular chain conveyor that is easy to install. It includes a workbench 1, a drive motor 2 fixedly connected to the left side of the top of the workbench 1, and a transmission shaft 3 rotatably connected to the right side of the top of the workbench 1. Both the front end of the transmission shaft 3 and the driving end of the drive motor 2 are fixedly connected to sprockets 4. The outer diameter of the sprockets 4 is connected via the inner side of a transmission chain 5. A connecting platform 7 is connected to the inner wall of the top of the workbench 1 via an installation assembly. The installation assembly includes a fixing frame 13 fixedly connected to both the left and right ends of the top of the connecting platform 7. A pressing plate 14 is slidably connected to the inner wall of the fixing frame 13. A traction plate 15 is rotatably connected to both the front and rear ends of the pressing plate 14. (See reference...) Figure 4 One end of the traction plate 15 is rotatably connected to a locking rod 11. The front and rear sides of the inner wall of the top of the worktable 1 are provided with a fitting groove 6. One end of the traction plate 15 is detachably connected to the inner wall of the fitting groove 6. The top of the pressing plate 14 is fixedly connected to a return spring 22. The top of the return spring 22 is fixedly connected to the top of the inner wall of the fixing frame 13.

[0020] Specifically, pressing the pressing plate 14 is a crucial step in the disassembly of the chain tensioning device for the tubular chain conveyor. When the pressing plate 14 is pressed, the traction plate 15 pulls the locking rod 11 inward, causing it to disengage from the engaging groove 6. This allows the connecting table 7 to be easily removed from the worktable 1, achieving rapid disassembly of the device. This design not only simplifies the disassembly process but also improves maintenance efficiency and reduces downtime. During installation, the reverse operation is equally convenient. The force of the return spring 22 presses the pressing plate 14, allowing the locking rod 11 to re-engage into the engaging groove 6, ensuring the connecting table 7 is securely fixed to the worktable 1. This design not only guarantees the reliability of the installation but also makes the entire installation process simpler and more efficient. From the perspective of ease of installation, this design of the tubular chain conveyor chain tensioning device fully considers the convenience of operation and the stability of the device, enabling both disassembly and installation to be completed in a short time, greatly improving work efficiency and reducing operational difficulty, thus providing significant convenience for equipment maintenance and upkeep.

[0021] Reference Figure 2-4 A fixed housing 8 is fixedly connected to the top of the connecting platform 7. A connecting frame 10 is slidably connected to the inner wall of the fixed housing 8. A toothed plate 18 is connected to the front end of the connecting frame 10 through a tensioning assembly. The mounting assembly includes a bearing shaft 12 rotatably connected to the inner wall of the connecting frame 10. A cross 16 is fixedly connected to the rear end of the outer wall of the bearing shaft 12. A sliding sleeve 20 is slidably connected to the front end of the outer wall of the bearing shaft 12. A rotating rod 19 is rotatably connected to the front end of the sliding sleeve 20. The rear end of the rotating rod 19 is threadedly connected to the inner wall of the bearing shaft 12. Support plates 21 are rotatably connected to the four sides of the outer walls at both ends of the outer wall of the sliding sleeve 20. Support frames 17 are rotatably connected to the opposite ends of the support plates 21. The rear end of the support frames 17 is slidably connected to the inner wall of the cross 16. The opposite ends of the toothed plates 18 are fixedly connected to the opposite ends of the support frames 17. A transmission screw 9 is rotatably connected to the inner wall of the fixed housing 8. The bottom end of the connecting frame 10 is rotatably connected to the outer wall of the transmission screw 9.

[0022] Specifically: When the drive motor 2 starts, the sprocket 4 is driven to rotate, which in turn drives the transmission chain 5 to rotate. The rotation of the transmission chain 5, through its connection with the tubular chain conveyor body, realizes the material conveying function. However, when the transmission chain 5 becomes loose, its position can be adjusted by rotating the rotating rod 19 to ensure its normal operation. The rotating rod 19 will move along the inside of the sliding sleeve tube 20, while the outside of the sliding sleeve tube 20 is connected to the support frame 17 through the support plate 21. The support frame 17 moves inside the cross 16, thereby causing the support frame 17 to cooperate with the toothed plate 18 and expand outward. This expansion action causes the toothed plate to... Plate 18 supports the inner side of the transmission chain 5, ensuring that the transmission chain 5 maintains appropriate tension and preventing the conveying efficiency from being affected by loosening. In addition, the bearing shaft 12 is designed to rotate at the connecting frame 10. This design ensures smooth rotation of the transmission chain 5 during the support process. At the same time, by rotating the transmission screw 9, the position of the connecting frame 10 can be adjusted, so that the connecting frame 10 drives the toothed plate 18 to pull, ensuring that the toothed plate 18 remains parallel to the transmission chain 5. This design not only facilitates installation but also enhances the practicality and reliability of the chain tensioning device of the tubular chain conveyor, ensuring that the conveyor maintains a highly efficient and stable working state during long-term operation.

[0023] Working principle: When the drive motor 2 starts, it drives the transmission chain 5 to rotate via the sprocket 4, thereby enabling it to transmit power to the connected tubular chain conveyor body and complete the conveying work. When the transmission chain 5 becomes loose, the rotating rod 19 is rotated to move it along the inside of the sliding sleeve tube 20. The support frame 17 moves through the inside of the cross 16 via the support plate 21 on the outside of the sliding sleeve tube 20, thus forming the support frame 17 cooperating with the toothed plate 18 to expand outwards. This allows the toothed plate 18 to support the inside of the transmission chain 5, ensuring the tension of the inside of the transmission chain 5. Furthermore, since the bearing shaft 12 can be connected to the connecting frame 1... The rotation at point 0 facilitates smooth rotational transmission during support. Rotating the transmission screw 9 allows the connecting frame 10 to move, causing it to pull the toothed plate 18, keeping the toothed plate 18 parallel to the transmission chain 5. When pressing the pressing plate 14, the traction plate 15 pulls the locking rod 11 inward, causing it to disengage from the mating groove 6, allowing the connecting table 7 to be removed from the workbench 1 for easy disassembly. In the reverse operation, the locking rod 11 is locked back into the mating groove 6 by the pressure of the return spring 22 on the pressing plate 14, facilitating installation.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
