Description

Technical Field

[0001] The present invention relates to the technical field of battery pack disassembly and assembly, and in particular to a tool for replacing an energy storage battery pack. Background Art

[0002] With the rapid development of the energy storage industry, battery compartments are becoming increasingly integrated. Energy storage system designs lack dedicated access for subsequent inspection and maintenance. As the capacity of individual battery packs increases, so does the weight and size of the packs. Furthermore, the space required to install the packs is limited, making manual installation and removal of the packs extremely difficult. Furthermore, battery packs are high-voltage hazardous materials, and any collisions or falls can compromise employee safety. With the rapid development of the energy storage industry, energy storage system designs feature a small footprint, a high degree of integration, and large battery pack capacity. However, as energy storage systems are an emerging industry, supporting inspection and maintenance technologies are immature, leading to frequent system failures. Battery packs sometimes require coordinated assembly and disassembly. Due to their inherent characteristics, weight, and installation requirements, manual installation and removal are extremely inconvenient. Furthermore, existing energy storage battery pack replacements currently require the use of a crane, which carries a high cost per crane use.

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 4 , the present invention provides a technical solution:

[0027] A tool for replacing an energy storage battery pack includes a lifting frame 1. A tray 11 is slidably provided on the lifting frame 1 via a lifting mechanism. The lifting mechanism can drive the tray 11 to slide up and down along the lifting frame 1. Multiple groups of rollers 12 are horizontally and equidistantly provided on the tray 11. The tray 11 is provided with:

[0028] The loading assembly is slidably arranged at the bottom of the tray 11. The loading assembly can be embedded in the bottom of the battery pack and can transfer the battery pack to the roller 12;

[0029] A positioning assembly is provided on one side of the tray 11 and can fix the battery pack on the tray 11 from the side wall and the top;

[0030] The unloading assembly is arranged at one end of the positioning assembly. The unloading assembly consists of two sets of toggle plates 9. The toggle plates 9 can be embedded in the side of the battery pack away from the tray 11. The unloading assembly can automatically adjust the spacing of the toggle plates 9 according to the size of the battery pack installation space.

[0031] In the present invention, when the battery pack is disassembled, the lifting frame 1 is moved close to the battery pack installation position to avoid the trouble of manual access and difficulty in disassembly and assembly due to the narrow installation position of the battery pack. During disassembly, the loading assembly on the lifting frame 1 is shoveled into the bottom of the battery pack so that the battery pack is above the loading assembly. At the same time, the positioning assembly moves synchronously with the loading assembly, so that the upper side of the battery pack is close to the battery pack, and the battery pack is pushed toward the roller 12 by the toggle plate 9 on the positioning assembly. The battery pack is driven to break away from the original installation position and fall onto the loading assembly through the pushing action. The loading assembly can drive the battery pack to gradually move above the roller 12, and then the lifting mechanism on the lifting frame 1 can drive the tray 11 to move upward, and then the battery pack can be driven upward, avoiding accidents during manual disassembly and installation, reducing personnel costs and improving work efficiency.

[0032] Among them, the loading assembly includes an export shovel plate 17, which is located below the roller 12 and is slidably connected to the tray 11 through a limit block 18. An inner guide wheel 20 is rotatably installed on one end of the export shovel plate 17, and an inclined surface is provided on the upper surface of the end away from the inner guide wheel 20. A transmission cloth 10 is connected to the outer shell of the export shovel plate 17, and the contact surface between the transmission cloth 10 and the inner guide wheel 20 is rough. A first motor is fixedly installed inside the export shovel plate 17, and the first motor can drive the inner guide wheel 20 to rotate clockwise, and the rotation of the inner guide wheel 20 can drive the transmission cloth 10 to rotate synchronously. During disassembly in the present invention, the export shovel plate 17 is driven to be exported from the tray 11, so that the export shovel plate 17 is close to the battery pack, and the export shovel plate 17 is on the lower side of the battery pack. The first motor in the export shovel plate 17 drives the inner guide wheel 20 to rotate, and the rotation of the inner guide wheel 20 drives the transmission cloth 10 to rotate toward the roller 12 (that is, clockwise rotation, such as Figure 4 The battery pack is gradually moved toward the roller 12 by the transmission cloth 10, so that the battery pack can be moved slowly and evenly to the top of the roller 12, thereby reducing damage to the battery pack during the disassembly and transportation process and reducing the possibility of accidents.

[0033] Among them, the positioning assembly includes a limit plate 6 and a lower telescopic rod 15. The lower telescopic rod 15 is fixedly installed on one side of the pallet 11. The limit plate 6 is arranged on the side of the pallet 11 away from the lower telescopic rod 15. A sliding rod 16 is fixedly installed between the free end of the lower telescopic rod 15 and the lower end of the limit plate 6. The sliding rod 16 is slidably connected to the pallet 11. The upper end of the limit plate 6 is provided with a horizontal telescopic rod 8 through the unloading assembly. The extension direction of the horizontal telescopic rod 8 is consistent with the sliding direction of the export shovel plate 17. In the present invention, when one side of the battery pack abuts against the limit plate 6, the battery pack stops moving, and the roller 12 stops rotating at this time. The limit plate 6 is used as a positioning plate on one side of the battery pack after disassembly and assembly, and at the same time the horizontal telescopic rod 8 is also above the battery pack. The horizontal telescopic rod 8 contracts and drives the toggle plate 9 to abut against the other side of the battery pack, and the horizontal telescopic rod 8 moves downward to abut against the upper surface of the battery pack, thereby fixing the position of the battery pack, and the distance between the limit plate 6 and the tray 11 can be changed by extending and shortening the lower telescopic rod 15, so that the device can adapt to different battery pack disassembly and assembly.

[0034] Among them, the unloading assembly includes a horizontal threaded rod 19, which is rotatably connected to the upper end of the limit plate 6. The middle position of the horizontal threaded rod 19 is used to distinguish the opposite directions of the threads on both sides. Both ends of the horizontal threaded rod 19 are threadedly connected to the vertical telescopic rod 7, and the vertical telescopic rod 7 is fixedly connected to the horizontal telescopic rod 8. The toggle plate 9 is fixedly installed on the end of the horizontal telescopic rod 8 away from the vertical telescopic rod 7. The upper end of the limit plate 6 is fixedly installed with a second motor, and the output end of the second motor is fixedly connected to the horizontal threaded rod 19. Some battery packs are stuck in the installation position and need to be disassembled and assembled manually, but the space is small and it is difficult for manual access to operate. The horizontal telescopic rod 8 can be used to drive the toggle plate 9 to introduce it into the installation. The toggle plate 9 is set on the side of the battery pack away from the roller 12. The horizontal telescopic rod 8 drives the toggle rod 9 to push the battery pack so that the battery pack is disengaged from the installation position, avoiding the trouble of manual access in the past. The spacing between the horizontal telescopic rods 8 can be adjusted by rotating the horizontal threaded rod 19. The horizontal threaded rod 19 rotates forward to move the horizontal telescopic rods 8 away from each other, and the horizontal threaded rod 19 rotates backward to move the horizontal telescopic rods 8 closer to each other, so that it can adapt to the disassembly and assembly of battery packs in different installation spaces.

[0035] A tilting plate 13 is fixedly mounted on the end of the tray 11 away from the stop plate 6. The upper end of the tilting plate 13 contacts the upper side of the roller 12, while the lower end contacts the upper surface of the transmission cloth 10. Multiple sets of inner rollers 14 are rotatably mounted on the tilting plate 13. Driven by the transmission cloth 10, the battery pack approaches the tilting plate 13 and is gradually moved onto the roller 12 by the rotation of the inner rollers 14 on the tilting plate 13.

[0036] The lifting mechanism includes a vertical threaded rod 3, which is rotatably connected to the lifting frame 1. A lifting plate 5 is threadedly connected to the vertical threaded rod 3. The tray 11 is fixedly mounted on the upper surface of the lifting plate 5. One end of the lifting plate 5 is slidably connected to the lifting frame 1. A bidirectional motor 4 is fixedly mounted on the bottom of the lifting frame 1, and the output end of the bidirectional motor 4 is fixedly connected to the vertical threaded rod 3. The bidirectional motor 4 drives the vertical threaded rod 3 to rotate. The vertical threaded rod 3 interacts with the lifting plate 5, driving the tray 11 up and down through the lifting plate 5, thereby driving the battery pack to move.

[0037] The lower surface of the lifting frame 1 is fixedly mounted with a movable base 2, which has multiple sets of self-locking universal wheels fixedly mounted on its lower surface. The movable base 2 is filled with counterweights. The self-locking universal wheels and the movable base 2 drive the secondary tooling to move, and the counterweights can increase the stability of the device.

[0038] Among them, one side of the tray 11 is provided with multiple sets of rotating motors, which can drive the rollers 12 and inner rollers 14 to rotate. A transmission belt is provided between adjacent rollers 12 and adjacent inner rollers 14. The rotating motors of the present invention can drive the rollers 12 and inner rollers 14 to rotate, and the transmission belts between the rollers 12 and inner rollers 14 can drive multiple sets of rollers 12 and inner rollers 14 to rotate synchronously.
