Description

Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to cargo handling mechanisms, especially a marine bidirectional telescopic depalletizer. Background Technology

[0002] In the fields of ocean shipping, inland waterway shipping, and port logistics, efficient and rapid loading and unloading of cargo is a key link in improving logistics turnover efficiency and reducing operating costs. Destacking and stacking is one of the core processes in loading and unloading. Existing technologies for shipboard forklifts or stacker cranes have some drawbacks: the operating area on board is limited, and the passageways are narrow. Forklifts or stacker cranes, constrained by their large size and turning radius, find it difficult to move and turn flexibly within the limited space. The equipment needs to frequently turn around or move to handle cargo on different sides, while manual handling is labor-intensive and inefficient. Furthermore, ships may sway during loading and unloading due to factors such as wind, waves, and changes in load. Existing equipment has weak resistance to swaying, easily leading to asynchronous lifting on both sides of the lifting platform or structural instability. Utility Model Content

[0003] The purpose of this utility model is to provide a marine bidirectional telescopic destacking and palletizing machine to solve the technical problems of existing marine stacking machines, such as difficulty in moving flexibly in a limited space, asynchronous lifting on both sides of the lifting platform, and unstable structure.

[0004] This utility model provides a marine bidirectional telescopic depalletizing and palletizing machine, comprising four rectangularly arranged columns. Each column has a lower beam at its base and an upper beam at its top. A traveling mechanism is located on the lower side of the lower beam. Each column has a slide rail parallel to its height, and each slide rail has a slider. A lifting slide is located between the columns, with its four corners fixedly connected to the sliders. A fixed base is located on the lower side of the upper beam, and a dual-axis motor is fixedly mounted on the fixed base. The output shafts at both ends of the dual-axis motor are respectively connected to a first synchronous pulley. A first support seat is located on each side above the dual-axis motor on the fixed base, and a first synchronous pulley is located in each of the two first support seats. The transmission shaft has two second synchronous pulleys on each of the first transmission shafts. The two second synchronous pulleys are respectively positioned above the two first synchronous pulleys and are connected to the two first synchronous pulleys by a first synchronous belt. Two third synchronous pulleys are respectively arranged on the outer side of the second synchronous pulleys on the two first transmission shafts. A second support seat is arranged on each of the two bottom columns. A second transmission shaft is connected between the two second support seats. Two fourth synchronous pulleys are arranged at each end of the second transmission shaft. The fourth synchronous pulleys correspond one-to-one with the third synchronous pulleys. A second synchronous belt is connected between each fourth synchronous pulley and the corresponding third synchronous pulley. Side plates are fixedly arranged on the side of the lifting slide, and the side plates are fixedly connected to each of the second synchronous belts.

[0005] The lifting slide is equipped with a bidirectional fork mechanism, which includes a base fixedly mounted on the lifting slide. Two parallel forks are mounted on the base, forming a sliding pair with the base. The two forks can extend synchronously to the left or right side of the base. A fork drive motor is mounted on the base, and the output shaft of the fork drive motor is connected to a first gear. The first gear meshes with a second gear, and the second gear meshes with a first rack. The first rack is fixedly connected to one of the forks. The second gear is also connected to a third gear via a universal joint. The third gear meshes with a second rack, and the second rack is connected to the other fork.

[0006] Furthermore, the walking mechanism includes a walking drive device and walking wheels, with the power output end of the walking drive device connected to the walking wheels.

[0007] Compared with existing technologies, the advantages of this invention are positive and significant. The forklift mechanism of this invention can extend to the left and right sides of the base, allowing for handling of cargo positions on both sides without the need for overall equipment turning in narrow ship cabin passageways. This adapts to the limited space environment on board and reduces manual labor intensity. The universal joint can accommodate coaxial installation errors of the second and third gears. This invention, through four columns, four sets of slide rails, a dual-axis motor, dual drive shafts, two sets of first synchronous belts, and four sets of second synchronous belts, constitutes a high-precision and stable lifting mechanism, achieving synchronous lifting of both sides of the lifting platform and ensuring smooth lifting.

[0012] like Figures 1-3As shown, this utility model provides a marine bidirectional telescopic depalletizing and palletizing machine, including four rectangularly arranged columns 1. A lower beam 2 is provided at the bottom of each column 1, and an upper beam 3 is provided at the top of each column 1. A traveling mechanism is provided on the lower side of the lower beam 2. Each column 1 is provided with a slide rail 4, which is parallel to the height direction of the column 1. Each slide rail 4 is provided with a slider 5. A lifting slide 6 is provided between the columns 1, and the four corners of the lifting slide 6 are fixedly connected to each slider 5. A fixed seat 7 is provided on the lower side of the upper beam 3. A dual-axis motor 8 is fixedly mounted on the fixed seat 7. The output shafts at both ends of the dual-axis motor 8 are respectively connected to a first synchronous pulley 9. A first support seat 10 is provided on both sides above the dual-axis motor 8 on the fixed seat 7. A first drive shaft 11 is provided in each of the two first support seats 10. Each of the two first drive shafts 11 has two second synchronous pulleys 12, which are respectively positioned above the two first synchronous pulleys 9 and connected to the two first synchronous pulleys 9 by a first synchronous belt (not shown in the figure). Two third synchronous pulleys 13 are respectively provided on the outer side of the two first drive shafts 11. A second support seat 14 is provided on each of the two bottom columns 1, and a second drive shaft 15 is connected between the two second support seats 14. Two fourth synchronous pulleys 16 are respectively provided at both ends of the second drive shaft 15. The fourth synchronous pulleys 16 correspond one-to-one with the third synchronous pulleys 13. Each fourth synchronous pulley 16 is connected to a second synchronous belt (not shown in the figure) between it and the corresponding third synchronous pulley 13. A side plate 17 is fixedly provided on the side of the lifting slide 6, and the side plate 17 is fixedly connected to each of the second synchronous belts.

[0013] The lifting slide 6 is equipped with a bidirectional fork mechanism, which includes a base 18. The base 18 is fixedly mounted on the lifting slide 6. Two parallel forks 19 are mounted on the base 18. The two forks 19 and the base 18 form a sliding pair. The two forks 19 can extend synchronously to the left or right side of the base 18. A fork drive motor 20 is mounted on the base 18. The output shaft of the fork drive motor 20 is connected to a first gear (not shown in the figure). The first gear meshes with a second gear 21. The second gear 21 meshes with a first rack 22. The first rack 22 is fixedly connected to one of the forks 19. The second gear 21 is also connected to a third gear 24 through a universal joint 23. The third gear 24 meshes with a second rack 25. The second rack 25 is connected to the other fork 19.

[0014] Furthermore, the walking mechanism includes a walking drive device and walking wheels, with the power output end of the walking drive device connected to the walking wheels.

[0015] Specifically, the walking mechanism, dual-axis motor 8, synchronous pulley, synchronous belt and other parts not described in detail in this utility model adopt the known solutions in the prior art, which are already known to those skilled in the art, and will not be described in detail here.

[0016] The working principle of this utility model:

[0017] The traveling mechanism drives the palletizer to the desired position. The dual-axis motor 8 drives two first synchronous pulleys 9 to rotate. These pulleys 9, in turn, drive two second synchronous pulleys 12 via a first synchronous belt. The second synchronous pulleys 12, through a first transmission shaft 11, drive a third synchronous pulley 13. The third synchronous pulley 13 and the fourth synchronous pulley 16 work together to drive the second synchronous belt. These four second synchronous belts then move the lifting slide 6 along the slide rail 4. When the lifting slide 6 is stationary, the fork drive motor 20 is activated. When the output shaft of the fork drive motor 20 rotates forward, it drives the first gear to rotate. The first gear drives the second gear 21 to rotate, which in turn drives the first rack 22 to move to the right. Simultaneously, the second gear 21 also drives the third gear 24 via a universal joint 23. The third gear 24 drives the second rack 25 to move to the right. The first rack 22 and the second rack 25 then drive the two forks 19 to extend synchronously to the right. Similarly, when the output shaft of the fork drive motor 20 rotates in the opposite direction, the two forks 19 extend synchronously to the left.

[0018] The forklift mechanism of this invention can extend to the left and right sides of the base 18, allowing for handling of cargo positions on both sides without the need for overall equipment turning in narrow ship cabin passages. This adapts to the limited space environment on board and reduces manual labor intensity. The universal joint 23 can accommodate the coaxial installation error of the second gear 21 and the third gear 24. This invention, through four columns 1, four sets of slide rails 4, a dual-axis motor 8, dual drive shafts, two sets of first synchronous belts, and four sets of second synchronous belts, constitutes a high-precision and stable lifting mechanism, achieving synchronous lifting of both sides of the lifting platform 6 and ensuring smooth lifting.
