Description

Technical Field

[0001] This utility model relates to the field of unloading technology, and more specifically, it relates to a rapid docking and unloading device for a suction crane. Background Technology

[0002] Currently, most overhead conveyor cranes use a fixed suction position design for their quick docking and unloading devices. This means that once the equipment is set up, the suction position cannot be adjusted according to different work requirements. This design flaw makes the equipment less adaptable when handling unloading boxes or containers of different sizes and shapes. In particular, when flexible adjustments are needed based on changes in material type or unloading environment, it cannot meet the needs of operators. Because the suction position cannot be adjusted, material loss or incomplete unloading can easily occur when the unloading position and suction port do not match.

[0003] In existing technologies, pipe connections typically rely on complex mechanical devices or require manual adjustments by operators. This not only increases the complexity of the operation but also increases the safety risks of manual operation. At the same time, pipe disassembly often requires laborious operations, such as using manual tools or relying on mechanical devices for separation. This may not be able to be completed quickly in some emergency situations, affecting overall work efficiency. Utility Model Content

[0029] Please see Figures 1-5A rapid docking and unloading device for a suction crane includes a crossbeam 1, a crane lifting mechanism, a rapid docking mechanism, and a docking auxiliary mechanism. The crane lifting mechanism includes a sleeve 2, a lifting rod 3, a side frame 4, a hydraulic cylinder 5, mating holes 6, and a locking bolt 7. The lifting rod 3 is installed at the bottom end of the crossbeam 1 and slides on the sleeve 2. The side frame 4 is installed on the side walls of the lifting rod 3 and the sleeve 2. The two ends of the hydraulic cylinder 5 are connected to the side frame 4. Multiple sets of mating holes 6 are provided on the lifting rod 3. The locking bolt 7 can pass through the sleeve 2 and the mating holes 6 to fix the rod, enabling rapid docking. The docking mechanism includes a snap-fit ​​outer tube 8, a snap-fit ​​inner tube 9, a movable frame 10, an insertion frame 11, a snap-fit ​​groove 12, a fixed frame 13, and a connecting groove 14. The snap-fit ​​inner tube 9 can extend into the snap-fit ​​outer tube 8. The snap-fit ​​groove 12 is provided on the side wall of the snap-fit ​​inner tube 9. The insertion frame 11 is slidably mounted laterally on the side wall of the snap-fit ​​outer tube 8. The fixed frame 13 is fixedly mounted on the outer wall of the snap-fit ​​outer tube 8. The movable frame 10 is slidably mounted longitudinally on the outer wall of the snap-fit ​​tube. The connecting groove 14 is provided on the fixed frame 13 and the movable frame 10. The two ends of the insertion frame 11 are slidably connected with the connecting groove 14.

[0030] In this embodiment, the position of the lifting rod 3 is controlled by a hydraulic cylinder 5. One end of the hydraulic cylinder 5 is connected to the side frame 4, and the other end is connected to the lifting rod 3. When the hydraulic cylinder 5 is running, the lifting rod 3 slides up and down along the sleeve 2, controlling the lifting and lowering of the crossbeam 1. The lifting rod 3 and the sleeve 2 are fixed together by multiple mating holes 6 and locking bolts 7. The locking bolts 7 lock the lifting rod 3 through the sleeve 2 and the mating holes 6, ensuring that the position of the lifting rod 3 will not accidentally shift or loosen during operation. This provides stable support for subsequent docking and unloading operations. The height of the crossbeam 1 can be adjusted as needed, allowing the overhead crane to flexibly adjust its position relative to the unloading box and engage with the inner... Pipe 9 can extend into the snap-fit ​​outer pipe 8. When the two pipes are connected, the snap-fit ​​groove 12 fixes the inner pipe and the outer pipe together. The extension frame 11 can slide laterally, making the connection between the snap-fit ​​inner pipe 9 and the outer pipe more precise and stable. The moving frame 10 is slidably installed on the snap-fit ​​outer pipe 8. Through the linkage between the connecting groove 14, the fixed frame 13 and the moving frame 10, it is ensured that the inner and outer pipes can be accurately positioned when connected. The outer wall of the snap-fit ​​outer pipe 8 is connected to the suction pipe 26 through the connecting plate 27, ensuring that the suction pipe 26 can smoothly suck up the material in the unloading box after the connection is completed.

[0031] The docking auxiliary mechanism includes a drive motor 15, a rotating gear 16, an external gear ring 17, a rotating frame 18, a top support frame 19, and a return spring 20. The rotating gear 16 is installed at the output end of the drive motor 15. The external gear ring 17 is rotatably limited and installed on the outer wall of the clamping tube. The rotating gear 16 meshes with the external gear ring 17. The top support frame 19 is installed at the top end of the moving frame 10. The rotating frame 18 is installed at the bottom end of the external gear ring 17. The rotating frame 18 causes the top support frame 19 and the moving frame 10 to move longitudinally. The return spring 20 is installed between the moving frame 10 and the fixed frame 13.

[0032] In this embodiment, the drive motor 15 drives the outer gear ring 17 through the rotating gear 16. The outer gear ring 17 restricts rotation and meshes with the rotating gear 16. The outer gear ring 17 drives the top frame 19 through the rotating frame 18, thereby moving the moving frame 10 longitudinally, so that the inner tube 9 and the outer tube are precisely connected. The return spring 20 is installed between the moving frame 10 and the fixed frame 13. It is used to automatically return to the original position after unloading to maintain the stability of the equipment. The function of the return spring 20 can also prevent the equipment from being affected by too much external force during the docking process, ensuring the smooth completion of the docking work.

[0033] Please see Figures 1-5 As a supplementary embodiment of a quick docking and unloading device for a suction crane, which includes a crane lifting mechanism, a quick docking mechanism, and a docking auxiliary mechanism: A base frame 21 is installed at the bottom end of the sleeve 2, and a caster wheel 22 is installed at the bottom end of the base frame 21. A suction box assembly 23 is installed on the crossbeam 1, and the positions of the crossbeam 1 and the suction box assembly 23 are adjusted by the caster wheel 22. Threaded brackets 24 are installed at the front and rear ends of the base frame 21, and a grounding rod 25 is threadedly connected to the threaded bracket 24. A suction pipe 26 is installed at the bottom end of the suction box assembly 23. A connecting plate 27 is installed at one end of the outer wall of the clamping pipe, and the clamping outer pipe 8 is connected to the suction pipe 26 through the connecting plate 27. A flexible hose 28 is installed at one end of the clamping inner pipe 9, and one end of the flexible hose 28 extends into the external unloading box. A support plate 29 is fixedly installed on the outer wall of the clamping outer pipe 8, and a drive motor 15 is installed on the support plate 29.

[0034] More specifically, the overhead crane lifting mechanism first drives the lifting rod 3 to slide up and down via the hydraulic cylinder 5, adjusting the position of the crossbeam 1 and the suction box to ensure a smooth docking process. When the crossbeam 1 and the suction box are adjusted to the correct position, the inner clamping tube 9 extends into the outer clamping tube 8. The sliding of the moving frame 10 and the extending frame 11 helps ensure the precise docking position of the inner and outer tubes. At this time, the outer clamping tube 8 and the suction pipe 26 are fixed by the connecting plate 27 to ensure a stable connection between the suction box and the unloading system. The drive motor 15 in the docking auxiliary mechanism drives the outer gear ring 17 to rotate via the rotating gear 16. The rotating frame 18 drives the top frame 19 to further adjust the docking position of the inner and outer pipes. This process ensures the accuracy and stability of the docking of the two pipes. After docking, the material in the suction box is transported to the unloading box through the cooperation of the clamping pipe and the hose 28. The universal wheels 22 installed under the base frame 21 allow the crane to move flexibly and adjust the relative position between the suction box assembly 23 and the crane. The cooperation between the threaded frame 24 at the front and rear ends of the base frame 21 and the grounding rod 25 further enhances the stability of the equipment and prevents unnecessary movement or vibration during the unloading process.

[0035] In summary, during the use or operation of the overall equipment: when the overhead crane lifting mechanism needs to operate, the position of the lifting rod 3 is controlled by the hydraulic cylinder 5. One end of the hydraulic cylinder 5 is connected to the side frame 4, and the other end is connected to the lifting rod 3. When the hydraulic cylinder 5 operates, the lifting rod 3 slides up and down along the sleeve 2, controlling the lifting and lowering of the crossbeam 1. The lifting rod 3 and the sleeve 2 are fixed together by multiple mating holes 6 and locking bolts 7. The locking bolts 7 lock the lifting rod 3 through the sleeve 2 and the mating holes 6, ensuring that the position of the lifting rod 3 will not accidentally shift or loosen during operation. This provides stable support for subsequent docking and unloading operations. The height of the crossbeam 1 can be adjusted according to requirements, allowing the overhead crane to flexibly adjust its position relative to the unloading box, thereby adapting to unloading requirements at different heights.

[0036] When the quick docking mechanism is in operation, the snap-fit ​​inner tube 9 can extend into the snap-fit ​​outer tube 8. When the two tubes dock, the snap-fit ​​groove 12 fixes the inner tube and the outer tube together. The extension frame 11 can slide laterally, making the docking between the snap-fit ​​inner tube 9 and the outer tube more precise and stable. The moving frame 10 is longitudinally slidably installed on the snap-fit ​​outer tube 8. Through the linkage between the connecting groove 14, the fixed frame 13, and the moving frame 10, it is ensured that the inner and outer tubes can be accurately positioned when docking. The outer wall of the snap-fit ​​outer tube 8 is connected to the suction pipe 26 through the connecting plate 27, ensuring that the suction pipe 26 can smoothly suck up the material in the unloading box after docking.

[0037] When the auxiliary docking mechanism is required to operate, the drive motor 15 drives the outer gear ring 17 through the rotating gear 16. The outer gear ring 17 restricts rotation and meshes with the rotating gear 16. The outer gear ring 17 drives the top support frame 19 through the rotating frame 18, thereby moving the moving frame 10 longitudinally, so that the inner tube 9 and the outer tube are precisely docked. The return spring 20 is installed between the moving frame 10 and the fixed frame 13 to automatically return to its original position after unloading, maintaining the stability of the equipment. The function of the return spring 20 can also prevent the equipment from being affected by too much external force during the docking process, ensuring the smooth completion of the docking work.

[0038] The overhead crane lifting mechanism first drives the lifting rod 3 to slide up and down via the hydraulic cylinder 5, adjusting the position of the crossbeam 1 and the suction box to ensure a smooth docking process. When the crossbeam 1 and the suction box are in the correct position, the inner clamping tube 9 extends into the outer clamping tube 8. The sliding of the moving frame 10 and the extending frame 11 helps ensure the precise docking position of the inner and outer tubes. At this time, the outer clamping tube 8 and the suction pipe 26 are fixed by the connecting plate 27, ensuring a stable connection between the suction box and the unloading system. The drive motor 15 in the docking auxiliary mechanism drives the outer gear ring 17 to rotate via the rotating gear 16. The frame 18 drives the top frame 19 to further adjust the docking position of the inner and outer pipes. This process ensures the accuracy and stability of the docking of the two pipes. After docking, the material in the suction box is transported to the unloading box through the cooperation of the clamping pipe and the hose 28. The casters 22 installed under the base frame 21 allow the crane to move flexibly and adjust the relative position between the suction box assembly 23 and the crane. The cooperation between the threaded frame 24 at the front and rear ends of the base frame 21 and the grounding rod 25 further enhances the stability of the equipment and prevents unnecessary movement or vibration during the unloading process.
