Detailed Implementation

[0017] See also Figure 1-4 This embodiment provides a battery packing and disassembly tooling for an energy storage battery compartment, including a main frame 1 and a push-pull mechanism 2, a guide mechanism 3, a stop mechanism 4, a limiting part 5, and a pipe clamping mechanism 6 disposed on the main frame 1.

[0018] The push-pull mechanism 2 includes a push-pull section 21 for moving the battery pack and a linear drive section 23. A chain 81 is connected to the push-pull section 21, and a hook 83 is connected to the free end of the chain 81. The linear drive section 23 is a ball screw linear module, and the push-pull section 21 is fixedly connected to the nut seat of the ball screw linear module. The ball screw linear module is equipped with a corresponding handwheel. In other embodiments, the linear drive section can also be a servo motor module powered by a battery.

[0019] The guiding mechanism 3 includes guide rollers 31 distributed along the moving direction of the push-pull part 21 and guide blocks 33 disposed on both sides of the main frame 1 along the moving direction. Multiple guide rollers 31 are disposed on both sides of the main frame 1 along the moving direction, and multiple guide rollers 31 located on the same side are arranged in close succession.

[0020] The stop mechanism 4 is located at one end of the main frame 1 along the direction of movement to stop the movement of the battery pack. The stop mechanism 4 can be stored inside the main frame 1 when not in use, and can be opened and popped out onto the surface of the main frame 1 when in use.

[0021] The limiting parts 5 are respectively provided on both sides of the main frame 1 along the moving direction to prevent the battery pack from tipping over. The limiting parts 5 include side limiting parts connected to the main frame 1 and top limiting parts that bend from the end of the side limiting parts to the surface of the main frame 1.

[0022] The pipe clamp mechanism 6 includes a pair of pipe clamps 61 disposed on both sides of the main frame 1 along the moving direction and perpendicular to the main frame 1 in the axial direction, two support column brackets 63 connected to the main frame 1, and two support columns 65 detachably mounted on the two support column brackets 63. The support columns 65 are mounted on the support column brackets 63 by wing screws, and the support columns 65 are adapted to the pipe clamps 61.

[0023] The push-pull mechanism 2, guide mechanism 3, stop mechanism 4, and limiting part 5 are all detachably connected to the main frame 1. The main frame 1 has several waist holes extending along the width direction of the battery pack, perpendicular to the direction in which the battery pack is pushed and pulled by the push-pull part 21. These waist holes are used to install guide blocks 33 and limiting blocks 5. The design of the waist holes allows for adjustable installation positions of the guide blocks 33 and limiting blocks 5, making them suitable for the assembly and disassembly of battery packs of different widths. The main frame 1 has lifting rings 91 for hoisting by the lifting mechanism and forklift handles 93 for forklift arm handling. Considering the harsh environment at the project site and the difficulty for most tooling and equipment to adapt to the site conditions, the main frame 1 also has a detachable dust cover 7, which is a bellows cover.

[0024] Specifically, such as Figure 1 As shown, the main frame 1 is welded together. Based on the main frame 1, the guide blocks 33 are integrated and installed at corresponding positions on both sides of the main frame 1. Their positions are adjusted using several slots on the main frame 1 according to the actual working conditions, and the screws are tightened after the working conditions are met. The limiting part 5 is integrated and installed at its corresponding position on the main frame 1. Its position is adjusted using several slots on the main frame 1 according to the actual working conditions, and the screws are tightened after the working conditions are met. After the guide rollers 31 are assembled, they are fixed to the main frame 1 as a sliding wheel to assist in guiding. When the battery pack is pushed into the box, the guide rollers 31 support the bottom of the box, reducing the pushing force and assisting in pushing the box in. The stopping mechanism 4 is installed above the main frame 1. When the entire pack is hoisted and placed, the stopping mechanism 4 is in an open state extending from the surface of the main frame 1. The stopping mechanism 4 blocks the pack, providing a limiting and stopping function to prevent the battery pack from sliding out and falling from the opposite end of the push-pull mechanism 2 during transport. The push-pull mechanism 2 first installs and adjusts the guide rail screw, then connects the assembled structural components to the guide rail slider. After assembly, the handwheel is cranked to verify the smoothness of the push-pull action. The pipe clamp mechanism 6, after installation, is secured to the side surface of the main frame 1 with screws. The dust cover 7 is detachably installed on the surface of the main frame 1 using screws; the overall assembly forms a rigid-flexible component.

[0025] The following are the instructions for using the battery pack unpacking and disassembly tooling in the energy storage battery compartment: Placement Procedure: Manually crank the handwheel to retract the push-pull mechanism 2, remove the limiting part 5, and manually reset the stop mechanism 4. Preparation is complete. Lift the PACK package and place it on the fixture, guided by the guide block 33 until the bottom surface of the box contacts the upper surface of the guide roller 31. Manually return the limiting part 5, crank the handwheel to push the push-pull part 21 against the PACK package, ensuring the stop mechanism 4 and the push-pull part 21 contact and are fixed in place with the PACK package, preventing significant shaking of the package on the fixture. Insert a forklift into the forklift slot 93 of the main frame 1 and lift and transfer the package (tightening bolts to brace against the forklift arm is recommended as needed). After completing the above steps, transfer the package to the energy storage cabinet. Once in place, manually loosen the wing screws securing the support column 65, remove the support column 65, and clamp it with pipe clamp 61. The support column 65 acts like scaffolding, preventing the fixture from shifting or tilting when the PACK package is pushed in but not yet in contact with the cabinet. The handwheel is manually cranked to release the force on the push-pull section 21, and the rotary stop mechanism 4 is manually pressed down to retract it. The handwheel is manually cranked again to push the PACK pack with the guide roller 31 assisting in the transmission from below, until the PACK pack is delivered into the energy storage cabinet. The pipe clamp 61 is manually released, the support column 65 is retracted, the support column bracket 63 is returned, and secured with wing screws. The placement and finishing operations are completed, and the forklift with the tooling drives away.

[0026] Pick-up Action: The forklift carrying the tooling travels to the pickup position in the storage cabinet. The operator manually loosens the wing screws, removes the support column 65, and clamps it with pipe clamp 61. The support column 65 provides support, preventing the tooling from shifting or tilting under force when the PACK is pulled out but not yet in contact with the storage cabinet and has not yet reached the center of the tooling. The operator manually screws the auxiliary lifting ring onto the PACK and manually adjusts the position of the push-pull part 21 by hand-cranking the handwheel, so that the hook 83 on the chain 81 can engage with the lifting ring on the PACK. After engagement, the operator manually cranks the handwheel to pull back the push-pull part 21, pulling the PACK into the tooling. After pulling back, the operator manually resets the stop mechanism 4, which now acts as a check valve, and manually pushes the PACK against the handwheel. After the push-pull is engaged, the operator manually releases the pipe clamp 61, retracts the support column 65, returns the support column bracket 63, and secures it with the wing screws. The pickup and finishing actions are complete, and the forklift carrying the tooling drives away to the repair position.

[0027] This utility model's battery pack disassembly and assembly fixture for energy storage battery compartments employs a push-pull mechanism, a guide mechanism, and a stop mechanism. This design allows the fixture to precisely align with the battery pack within the battery compartment, enabling smooth and rapid extraction. This significantly improves disassembly efficiency, reduces disassembly difficulty, and shortens the disassembly time to approximately 15 minutes. It effectively enhances the efficiency and safety of assembling and disassembling energy storage battery packs in integrated battery compartments under on-site conditions. The fixture design is compatible with both forklift and crane handling methods, making it well-suited to harsh on-site environments and eliminating the need for hardened cement surfaces or a flat foundation.
