DETAILED DESCRIPTION
[0021] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.
[0022] like Figure 1-5 As shown, the automatic dock crane of this embodiment includes cantilever beams 1 located on the dock in sequence, a hoisting assembly 2 for loading and unloading goods is provided between two adjacent cantilever beams 1, a guide rail 3 for moving the hoisting assembly 2 is provided on the upper part of the cantilever beam 1, the hoisting assembly 2 includes a crossbeam 4, and a walking mechanism used in conjunction with the guide rail 3 is provided at both ends of the crossbeam 4, the walking mechanism includes a walking wheel and a driving source, a walking trolley 5 moving along the length direction of the crossbeam 4 is provided in the middle part of the crossbeam 4, a sling 6 is provided on the walking trolley 5, and a clamp 7 for loading and unloading goods is provided at the lower part of the sling 6, the material is clamped by the clamp 7 and then the lifting operation is completed by the sling, and finally the goods are transferred from the ship to the storage area by the walking mechanism, and the design of the walking trolley 5 can transfer materials at different positions on the ship.
[0023] The clamping jaw 7 includes a base 8 connected to the sling 6, a connecting seat 9 is provided on the upper part of the base 8, and two groups of symmetrically distributed clamping arms 10 are provided on the lower part. After the base 8 is connected to the sling 6 through the connecting seat 9, it can complete the movement and lifting actions, and the clamping arm 10 can clamp the material to ensure that the material moves with the clamping jaw 7.
[0024] A driving gear disc 11 is provided on the upper part of the clamping arm 10, and the driving gear discs 11 on the upper parts of the two groups of clamping arms 10 are meshed and connected. A rotating rod 12 is provided on one group of the driving gear discs 11, and a driving motor 13 is provided at the end of the rotating rod 12. The rotation of the driving gear disc 11 can drive the two groups of clamping arms 10 to complete the opening and closing operation, thereby completing the clamping and transfer of the material.
[0025] The sling 6 includes a winding wheel 14, on which a lifting rope 15 is provided, and the lower end of the lifting rope 15 is provided with a switching assembly detachably connected to the clamp 7, and the switching assembly includes a cross brace 16, and the upper part of the cross brace 16 is provided with a hanging ring 17 connected to the lifting rope 15, and the lower part is provided with a hook group connected to the clamp 7. The hook group is used to complete the detachable connection with the clamp 7. The structure is simple, the operation is convenient, and the replacement operation of the clamp 7 can be completed quickly.
[0026] The hook group includes a main hook 18 located in the middle of the cross brace 16, and auxiliary hooks 19 are arranged on both sides of the main hook 18. A mounting seat 20 for installing the auxiliary hook 19 is arranged in the cross brace 16, and a avoidance groove 21 for placing the mounting seat 20 is arranged inside the cross brace 16. A telescopic rod 22 connected to the mounting seat 20 is arranged in the avoidance groove 21. The distance between the two auxiliary hooks 19 and the main hook 18 can be adjusted by the telescopic rod 22. When transporting materials of different sizes, the installation of clamps 7 of different sizes can be completed by adjusting the distance between the main hook 18 and the auxiliary hook 19.
[0027] Working principle / assembly process of this solution: a guide rail 3 is laid on the upper part of the cantilever beam 1 at the berthing position of the dock, and then the crossbeam 4 is installed on the guide rail 3 so that it can move along the length direction of the cantilever beam 1 to transfer the materials on the ship to the storage area. The walking trolley 5 on the crossbeam 4 can move between the two cantilever beams 1 to transfer materials at different positions on the ship. The design of the sling 6 and the clamp 7 can complete the clamping and lifting operations of the materials. The advantage of this solution is that the cantilever beam 1 on the dock can be used as a support for the crossbeam 4, which simplifies the installation process and saves equipment investment costs. Compared with conventional gantry-type lifting equipment, this equipment has a smaller footprint, and the moving space is located on the upper part of the entire dock, saving the transportation space in the lower part, and multiple equipment can be distributed in parallel horizontally, so that the materials on the ship can be loaded and unloaded at multiple points and multiple areas at the same time, thereby improving the material loading and unloading efficiency.
