Description
Technical Field
[0001] This utility model relates to the field of battery swapping technology for bridge cranes, specifically a battery swapping system for bridge cranes capable of operating across bays. Background Technology
[0002] Currently, bridge cranes are widely used in port container handling operations. Port operating areas are divided into multiple bays, which serve as the basic units for container stacking. Traditionally, a separate bridge crane is configured for each bay, resulting in a large overall number of equipment and significantly increasing initial investment and subsequent operating costs. To address these issues, existing technologies have developed bridge cranes capable of operating across bays. These cranes can flexibly move between different bays to complete container loading and unloading, eliminating the need for a separate crane for each bay. These bridge cranes capable of operating across bays rely on battery packs for continuous operation. However, current battery swapping methods are mostly manual, which not only inconveniences maintenance personnel but also results in low efficiency in scenarios requiring frequent battery swapping. Utility Model Content
[0003] To address the aforementioned shortcomings, this utility model proposes a battery swapping system for a bridge crane capable of operating across bays. The aim is to solve the problem that existing bridge cranes capable of operating across bays rely on battery packs for power to maintain operation. However, current battery swapping methods are mostly manual, which not only causes inconvenience to maintenance personnel but also results in low battery swapping efficiency in scenarios requiring frequent swapping.
[0004] To achieve this goal, the present invention adopts the following technical solution: A battery swapping system for a bridge crane capable of operating across bays includes a bay support frame, a bay flatcar, a charging device support frame, and a charging device. The cross-bay flatcar is slidably mounted on the top of the cross-bay support frame, and the cross-bay flatcar is used to carry the bridge crane; the left and right sides of the charging device support frame are respectively mounted on the left and right sides of the cross-bay flatcar, and the charging device is located on the top of the charging device support frame. The charging device is used to transfer and charge the depleted battery pack in the battery compartment of the bridge crane, or to transfer the fully charged battery pack to the battery compartment of the bridge crane to supply power to the bridge crane.
[0005] Preferably, the charging device includes a support platform, a lifting and transferring component, a picking and placing component, and a plurality of charging piles. The support platform is provided with a battery swapping port, which extends through the top and bottom surfaces of the support platform. The support platform is installed on the top of the charging device support frame. The lifting and transferring assembly, the picking and placing assembly, and a plurality of charging piles are all disposed on the top surface of the support platform. The picking and placing assembly and the battery swapping port are located on the same horizontal line. The lifting and transferring assembly is disposed correspondingly to the battery swapping port. The plurality of charging piles are evenly distributed on the front and rear sides of the picking and placing assembly. The lifting and transferring assembly is used to transfer a depleted battery pack from the battery compartment of the bridge crane to the support platform, or to transfer a fully charged battery pack to the battery compartment of the bridge crane. The picking and placing assembly is used to grab or release the battery pack.
[0006] Preferably, the pick-and-place assembly includes a running track and a six-axis robot; the running track is installed on the top surface of the support platform and extends in the left-right direction, and the six-axis robot is slidably installed on the running track in the left-right direction.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0016] A battery swapping system for a bridge crane capable of operating across bays includes a bay support frame 1, a bay flatcar 2, a charging device support frame 3, and a charging device 4. The cross-bay flatcar 2 is slidably mounted on the top of the cross-bay support frame 1. The cross-bay flatcar 2 is used to carry the bridge crane 5. The left and right sides of the charging device support frame 3 are respectively mounted on the left and right sides of the cross-bay flatcar 2. The charging device 4 is located on the top of the charging device support frame 3. The charging device 4 is used to transfer and charge the depleted battery pack 6 in the battery compartment (not shown in the figure) of the bridge crane 5, or to transfer the fully charged battery pack 6 to the battery compartment of the bridge crane 5 to supply power to the bridge crane 5.
[0017] This solution includes a power swapping system for a bridge crane capable of operating across bays, such as... Figure 1As shown, when the bridge crane 5 needs battery replacement, firstly, the bridge crane 5 is precisely moved to the preset bearing position of the cross-crane flatcar 2 and positioned. Then, the charging device 4 is activated, automatically performing the following actions: first, the depleted battery pack 6 is removed from the battery compartment of the bridge crane 5 and transferred to its own charging station; then, the depleted battery pack 6 is charged, and simultaneously, a pre-stored fully charged battery pack 6 is precisely transferred to the battery compartment of the bridge crane 5 and positioned, achieving rapid power replenishment for the bridge crane 5 and ensuring its immediate resumption of cross-crane operations. Further explanation is provided: the cross-crane support frame 1 provides support for the cross-crane flatcar 2 and the bridge crane 5. Since the cross-crane flatcar 2 is slidably mounted on the top of the cross-crane support frame 1, the sliding of the cross-crane flatcar 2 can drive the bridge crane 5 mounted on it to move synchronously, thereby enabling switching between different cross-crane positions and adapting to the flexible scheduling requirements of cross-crane operations.
[0018] In this solution, the bridge crane 5 achieves automated battery swapping during bridge crane operations through the coordinated operation of the cross-bay flatcar 2 and the charging device 4. Compared to the traditional manual battery swapping method, the automated battery swapping method in this solution not only effectively avoids the inconvenience of manually handling battery packs, but also shortens the battery swapping time in frequent battery swapping scenarios, thereby improving battery swapping efficiency.
[0019] Preferably, the charging device 4 includes a support platform 41, a lifting and transferring component 42, a picking and placing component 43, and a plurality of charging piles 44. The support platform 41 is provided with a battery swapping port 410, which extends through the top and bottom surfaces of the support platform 41. The support platform 41 is installed on the top of the charging device support frame 3. The lifting and transferring component 42, the picking and placing component 43, and a plurality of charging piles 44 are all arranged on the top surface of the support platform 41. The picking and placing component 43 and the battery swapping port 410 are located on the same horizontal line. The lifting and transferring component 42 is arranged correspondingly to the battery swapping port 410. The plurality of charging piles 44 are evenly distributed on the front and rear sides of the picking and placing component 43. The lifting and transferring component 42 is used to transfer the depleted battery pack 6 in the battery compartment of the bridge crane 5 to the support platform 41, or to transfer the fully charged battery pack 6 to the battery compartment of the bridge crane 5. The picking and placing component 43 is used to grab or release the battery pack 6.
[0020] In this embodiment, as Figure 2As shown, when a battery swapping operation is required for the bridge crane 5, the bridge crane 5 is first driven to precisely move to the preset position of the cross-bay flatcar 2, so that the battery compartment of the bridge crane 5 is precisely aligned with the battery swapping port 410 of the support platform 41; then, the lifting and transferring assembly 42 is activated, which precisely removes the depleted battery pack 6 and transfers it through the battery swapping port 410 to the designated area of the support platform 41; next, the pick-and-place assembly 43 is activated to grab the battery pack 6. The depleted battery pack 6 on the support platform 41 is moved to an empty charging pile 44 and docked for charging. Then, since the pre-charged battery pack 6 is already placed in the corresponding charging pile 44, the pick-and-place component 43 can grab the battery pack 6 and move it to the lifting and transferring component 42. Finally, the lifting and transferring component 42 starts again, passing the fully charged battery pack 6 through the battery swapping port 410 and accurately transferring it into the battery compartment of the bridge crane 5, completing the entire battery swapping process. Further explanation: the charging pile 44 is connected to the industrial power supply network of the port operation area through a pre-set cable line to obtain a stable AC power supply.
[0021] Preferably, the pick-and-place assembly 43 includes a running track 431 and a six-axis robot 432; the running track 431 is installed on the top surface of the support platform 41 and extends in the left-right direction, and the six-axis robot 432 is slidably installed on the running track 431.
[0022] In this embodiment, as Figure 2 As shown, the end of the robotic arm of the six-axis robot 432 can be equipped with a gripper (not shown in the figure), which has the advantages of multi-degree-of-freedom rotation and extension. Combined with the running track 431 extending in the left and right direction, the six-axis robot 432 can slide left and right, so that the gripper can cover the charging piles 44 and the lifting and transfer components 42 at different positions on the support platform 41, and accurately grab or place the battery packs 6 to meet different transportation needs such as transferring the battery packs 6 with low power and retrieving the battery packs 6 with full power.
[0023] Preferably, the lifting and transferring component 42 is a hoist. In this embodiment, since the lifting and transferring component 42 is specifically a hoist, the hoist has stable vertical lifting and transferring functions, can accurately control the lifting height and transferring speed, ensures that the battery pack 6 is transferred smoothly without shaking, achieves precise docking with the battery compartment of the bridge crane 5 and the pick-and-place component 43, and improves the reliability of the battery swapping operation. In other embodiments, the lifting and transferring component 42 can be a gantry robot or a traction machine.
[0024] Preferably, it also includes two positioning posts 7, both of which are installed on the rear side of the cross-bay flatcar 2, and the two positioning posts 7 are symmetrically distributed from left to right. In this embodiment, as... Figure 1 As shown, during the process of the bridge crane 5 moving to the cross-bay flatcar 2, the bridge crane 5 enters along the front side of the cross-bay flatcar 2 and gradually approaches the preset position; the two positioning columns 7 located on the rear side of the cross-bay flatcar 2 can accurately position the bridge crane 5, ensuring that it is stably stopped at the preset position, and providing a guarantee for the accurate alignment of the battery compartment of the bridge crane 5 with the battery swapping port 410.
[0025] Preferably, the charging device support frame 3 includes four support columns 31 and a support plate 32; two of the support columns 31 are fixedly connected to the left and right sides of the cross-beam flatcar 2, and the two support columns 31 on each side are symmetrically distributed front and back; the support plate 32 is fixedly connected to the top of the four support columns 31. In this embodiment, as... Figure 1 As shown, since two support columns 31 are fixedly connected to the left and right sides of the cross-bay flatcar 2 respectively, and the two support columns 31 on each side are symmetrically distributed front and back, forming a symmetrical four-point support structure, in conjunction with the fixed connection of the support plate 32, the weight of the charging device 4 can be evenly distributed to the cross-bay flatcar 2, effectively avoiding structural deformation caused by excessive local stress on the charging device support frame 3.
[0026] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
