Abstract
Description
Technical Field
[0001] This utility model relates to the field of suspended conveyor belt technology, specifically to an anti-fall-off suspended conveyor belt. Background Technology
[0002] Suspended conveyor belts are an industrial conveying system that transports materials or products via carriers suspended from beams. This type of conveyor belt system is typically used in applications requiring long-distance transport, vertical or horizontal changes, and avoidance of ground obstacles.
[0003] As disclosed in patent announcement number CN219278571U, a suspended conveyor belt and its production line include a suspended rigid ring rail. Moving components are arrayed along the circumferential trajectory of the rigid ring rail. A hanging device is provided at the bottom of each moving component. The moving components are connected and spaced by a flexible chain. The ends of the rigid ring rail are equipped with drive wheels for propelling the moving components along the rigid ring rail and tension wheels for tensioning the flexible chain. The beneficial effects of adopting the above technical solution are: the tension adjustment component can be used to adjust the tension of the flexible chain, allowing for adaptive adjustment based on changes in metal expansion and contraction due to ambient temperature and variations in the conveying load.
[0004] Although the aforementioned patent can adapt to changes in metal expansion and contraction due to ambient temperature and changes in conveying load, the suspension structure uses hanging plates and hooks without any anti-detachment structure. During the conveying process, if the hooks shift due to vibration or external impact, the object may fall off the hooks and threaten the safety of personnel and equipment below. Utility Model Content

Detailed Implementation
[0012] 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.
[0013] like Figure 1-4 As shown, this utility model provides a technical solution: A suspended conveyor belt designed to prevent detachment includes a frame 1, with a motor 2 fixedly connected to its top right side. Inside the frame 1 is a conveying mechanism that works with the motor 2. The conveying mechanism includes a first synchronous pulley 6 and a second synchronous pulley 7, rotatably connected to both ends of the lower interior of the frame 1 via bearings. The first and second synchronous pulleys 7 mesh with the toothed synchronous belt 8. The output shaft of the motor 2 is fixedly connected to the first synchronous pulley 6. Guide rollers 9 are rotatably connected to both sides of the lower interior of the frame 1 via bearings, with their outer circumferences rolling in contact with the outer end face of the synchronous belt 8. Guide rollers 10 are rotatably connected to the other two sides of the lower interior of the frame 1 via bearings, with their outer circumferences rolling in contact with the outer end face of the synchronous belt 8. A third synchronous pulley 11 is rotatably connected to the lower interior of the frame 1, located on the inner ring side of the synchronous belt 8, via bearings. The third synchronous pulley 11 meshes with the synchronous belt 8, and its position relative to the guide rollers 10 is... Yes, the suspension frame 3 is evenly spaced below the conveying mechanism. The bottom end of the suspension frame 3 is connected to a horizontal bar 4 by bolts. The J-shaped hook 5 is fixedly connected to one side of the horizontal bar 4. The J-shaped hook 5 is equipped with an anti-drop mechanism, which includes an L-shaped anti-drop block 12 located on the outside of one side of the J-shaped hook 5, and a first inclined block 13 fixedly connected to the middle of the inner wall of the side of the J-shaped hook 5 away from the L-shaped anti-drop block 12. A guide rod 14 is fixedly connected to the top right side of the L-shaped anti-drop block 12. An movable hole 15 is opened on the left side of the bottom end of the J-shaped hook 5, which slides with the guide rod 14. The guide rod 14 passes through the movable hole 15 and is fixedly connected to a second inclined block 16 that is mirror-symmetrical to the first inclined block 13. The anti-drop mechanism also includes a telescopic groove 17 opened inside the left side of the J-shaped hook 5, and a spring 18 fixedly connected to the left side of the L-shaped anti-drop block 12 near the guide rod 14. The top end of the spring 18 extends into the inside of the telescopic groove 17 and is fixedly connected to the inner top wall of the telescopic groove 17. In this embodiment, the linkage between the L-shaped anti-detachment block 12 and the J-shaped hook 5, combined with the elastic reset effect of the spring 18, ensures that the hook remains in a normally closed state, effectively solving the major safety hazard of objects falling off due to vibration or collision in traditional suspended conveying devices, and significantly improving the safety of the conveying process.
[0014] Furthermore, through the inclined surface cooperation structure design of inclined block 13 and inclined block 2 16, combined with the guiding effect of guide rod 14, the rapid opening and closing function of the anti-detachment mechanism is realized. While ensuring the anti-detachment performance, the loading and unloading operation process is greatly simplified and the work efficiency is improved.
[0015] Working principle: When motor 2 starts, its output shaft drives synchronous pulley 6 to rotate. Power is transmitted through the toothed meshing of synchronous belt 8 and synchronous pulley 7. Under the drive of synchronous pulleys 6 and 7, synchronous belt 8 forms a circular motion trajectory. Synchronous pulley 11 further ensures transmission stability through meshing with synchronous belt 8. Guide rollers 10 and 9 provide rolling contact guidance to the outer end face of synchronous belt 8 from different sides to maintain the running trajectory of synchronous belt 8. Suspension frame 3 moves equidistantly with the movement of synchronous belt 8. When it is necessary to suspend an item, the operator pulls down the L-shaped anti-detachment block 12 and stretches the spring 18. At this time, guide rod 14 synchronously drives inclined block 16 to move down so that it forms a shape with inclined block 13. When the L-shaped anti-detachment block 12 is in a misaligned state, its displacement causes the inlet of the J-shaped hook 5 to be fully open. The hook end of the item is then inserted through the open inlet of the J-shaped hook 5 and enters the hook through the misaligned gap formed between the first inclined block 13 and the second inclined block 16. After hooking, the L-shaped anti-detachment block 12 is released, and the restoring force of the spring 18 causes the L-shaped anti-detachment block 12 to move upward and reset. The second inclined block 16 moves upward with the guide rod 14 and returns to the alignment state with the first inclined block 13 to form a limiting structure. At the same time, the L-shaped anti-detachment block 12 closes the inlet of the J-shaped hook 5. When unloading, the L-shaped anti-detachment block 12 needs to be pulled down again to make the second inclined block 16 misaligned with the first inclined block 13 before the item can be removed. The entire anti-detachment mechanism is kept in a normally closed state by the elastic force of the spring 18, and the hook inlet is only opened during manual operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
