Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 6 The present invention provides a technical solution: a convenient buckle device for container hoisting, comprising: two sets of parallel telescopic components and two sets of drive components located at both ends of the two sets of telescopic components, wherein the drive components are used to drive the telescopic components to move and fix the container.

[0021] Each telescopic component includes two support pipes 1. Each support pipe 1 has a caster wheel 2 installed at its lower end. Each support pipe 1 has a support plate 13 fixedly installed on its inner side. The support plate 13 is L-shaped. A guide slope 14 is opened on the outer side of one end of the support plate 13. Several guide wheels 15 are evenly rotatably connected to the upper side of one end of the support plate 13. When the drive component drives the telescopic component to move, the support plate 13 contacts the lower end of the container through the guide slope 14. Under the action of the guide wheels 15, the container is lifted to the upper end of the support plate 13, and the bottom of the container is supported on all four sides. A lifting plate 16 is fixedly installed at the other end of the support plate 13. A lifting ring 17 is fixedly installed at the upper end of the lifting plate 16. The lifting ring 17 is used to connect with the steel cable of the crane. The container can be lifted by the crane.

[0022] A movable tube 8 is provided between the two support tubes 1. Both ends of the movable tube 8 are inserted into the inner ends of the two support tubes 1 and connected by a limiting structure. The limiting structure includes two strip plates 3 fixed to the left and right sides of the inner ends of the support tubes 1, and toothed blocks 9 fixed to the outer walls of the left and right ends of the movable tube 8. One end of the toothed block 9 passes between the two strip plates 3, and a ramp is provided at one end of the toothed block 9 to facilitate insertion between the teeth of the toothed plate 5. A toothed plate 5 is provided on the other side of the strip plates 3, and one end of the toothed block 9 can mesh with the teeth on the toothed plate 5. The toothed plate 5 is located inside the support tube 1, and two sliding pillars 7 and several springs 6 are fixedly installed at one end of the toothed plate 5. The side wall of the support tube 1 is provided with a sliding hole 4 corresponding to the sliding column 7. The end of the spring 6 away from the toothed plate 5 is fixed on the inner wall of the support tube 1. At the same time, the sliding column 7 slides through the sliding hole 4 and is connected to the drive tube 10. After the sliding column 7 slides through the side wall of the drive tube 10, a baffle 31 is fixedly installed. The toothed plate 5 can move in the support tube 1 by squeezing the spring 6. When the spring 6 is in a balanced state, the toothed plate 5 and the toothed block 9 are engaged with each other. Under the action of the slope, the toothed block 9 squeezes the toothed plate 5. The toothed plate 5 squeezes the spring 6 and moves the sliding column 7 outward. The sliding column 7 slides on the drive tube 10, which makes it easier for the toothed block 9 and the moving tube 8 to move to one side in the support tube 1.

[0023] A second drive tube 11 is slidably inserted between two drive tubes 10. A hand-tightening bolt 12 is threaded onto the side wall of the middle part of the second drive tube 11. One end of the hand-tightening bolt 12 passes through the second drive tube 11 and is rotatably connected to the outer wall of the moving tube 8 through a bearing. By rotating the hand-tightening bolt 12, the side of the second drive tube 11 and the first drive tube 10 away from the support tube 1 can be determined. Under the action of the baffle 31, the sliding column 7 moves outward. The sliding column 7 moves synchronously with the toothed plate 5, which can separate the toothed plate 5 and the toothed block 9. The moving tube 8 can then be pulled out from the support tube 1, which is convenient for disassembling and assembling the device and for carrying it.

[0024] Each support pipe 1 has a detachable fixing plate 19 installed at the end away from the moving pipe 8. A threaded cylinder 20 is vertically fixed at the end of the fixing plate 19 away from the support pipe 1. A fixing sleeve 18 is fixedly installed at the end of the support pipe 1 away from the moving pipe 8. The end of the fixing plate 19 away from the threaded cylinder 20 is inserted into the fixing sleeve 18 and fixed with bolts, which facilitates the disassembly, assembly, and transport of the fixing plate 19.

[0025] The driving component includes a support plate 21, with a caster wheel 22 mounted on the lower end of the support plate 21. A threaded rod 26 is rotatably connected to the upper end of the support plate 21 via a support seat 25. The threads at both ends of the threaded rod 26 are symmetrically arranged. Support seats 25 are fixedly mounted on both sides of the upper end of the support plate 21, and bearings are fixedly mounted on the upper ends of the two support seats 25. The threaded rod 26 passes through the bearings at the upper ends of the two support seats 25 and is fixedly connected to the inner wall of the bearing. A U-shaped plate is fixedly mounted on the upper end of the support plate 21, and a drive motor 23 is fixedly mounted inside the U-shaped plate. A steering gear 24 is fixedly installed at the output end of the drive motor 23. Two steering gears 24 are symmetrically fixedly installed on the outer wall of the threaded rod 26. The steering gear 24 on one side of the drive motor 23 and the steering gear 24 on the threaded rod 26 are meshed and connected to each other. When the drive motor 23 starts, it can drive the threaded rod 26 to rotate in both directions. Both ends of the threaded rod 26 extend out of the outer side of the support plate 21 and are inserted into the threaded cylinder 20 and threadedly connected to the inner wall of the threaded cylinder 20. When the threaded rod 26 rotates, it can drive the telescopic components on both sides to move synchronously inward or outward.

[0026] like Figure 1 and Figure 6 As shown, in some embodiments, a limiting component is provided on one side of the support plate 21. The limiting component includes a side plate 27 fixedly installed on the inner side of the upper end of the support plate 21. A threaded post 28 is threadedly connected to the upper end of the side plate 27. One end of the threaded post 28 passes through the side plate 27 and is rotatably connected to a limiting plate 29 through a bearing. Two guide rods 30 are symmetrically fixedly installed on the side wall of the limiting plate 29. One end of the guide rod 30 slides through the side wall of the side plate 27. When the pallet 13 lifts the lower end of the container, the limiting plate 29 is driven to contact the front and rear sides of the container by rotating the threaded post 28, thereby further limiting the container.

[0027] When this device is in operation, by setting two sets of telescopic components on the front and rear sides of the container, the left and right ends of the moving tube 8 are inserted into the two support tubes 1, that is, the pallet 13 is adjusted to a suitable position, and the fixing plate 19 is fixedly installed on the outside of the support tube 1. The two driving components are set on the left and right sides of the container, and the front and rear ends of the threaded rod 26 are respectively threadedly connected to the inner walls of the two threaded cylinders 20. When the drive motor 23 starts, it drives the threaded rod 26 to rotate, which can drive the telescopic components on both sides to move inward synchronously. The pallet 13 contacts the lower end of the container through the guide slope 14, and under the action of the guide wheel 15, the container is lifted to the upper end of the pallet 13, and the bottom of the container is supported on all four sides. By rotating the threaded column 28, the limiting plate 29 is driven to contact the front and rear sides of the container, further limiting the container. Finally, the container is lifted and transported by a crane.
