Description

Technical Field

[0001] This utility model relates to the field of battery pack storage and transportation technology, specifically to a disassembly tooling for large energy storage battery packs suitable for narrow spaces and sloping work surfaces. Background Technology

[0002] With the continuous advancement of my country's dual-carbon strategy, containerized energy storage is being used more and more on both the power generation and consumption sides. The entire container is hoisted onto a prefabricated foundation, connected with the corresponding cables, and ready for power operation. Its user-friendly installation is highly welcomed by the market. However, as the built-in battery packs become larger, the difficulty for after-sales maintenance personnel to disassemble and install them is increasing, posing greater challenges to the methods and tools used in the operation.

[0003] The battery container's interior is filled with rows of battery racks, each with nine slots, similar to drawer slots. The battery packs, like drawers, are pushed into these slots and secured. The other side of the container has the same structure. Each battery pack is 1.1 meters long, slightly less than half the container's width, and weighs approximately 350 kg. Installation requires jigs and stacking machinery. First, the battery pack is hoisted onto the jigs, then lifted to a suitable height using the stacker, and finally pushed horizontally into its slot. This process must ensure the battery pack doesn't slip during lifting and minimize resistance during horizontal pushing to reduce labor intensity.

[0004] However, battery packs are not maintenance-free for their entire lifespan. This means that throughout the battery's lifespan, it's inevitable that the battery pack will need to be removed for maintenance, such as replacing faulty individual cells or performing offline capacity balancing. This requires on-site maintenance personnel to disassemble the battery pack, and then reassemble it after repairs. In particular, disassembling the battery pack involves pulling a 350kg battery out of its slot. This sliding friction process presents significant resistance, and the movement distance is over a meter, making it impossible to complete manually. Mechanical tooling is often required for lifting and pulling, making the battery pack disassembly and maintenance process heavily dependent on on-site working conditions. If the working environment is similar to that of the production plant, the production equipment and tooling can be used. However, some on-site conditions differ significantly from factory production. For example, some installation scenarios are limited by the shape and size of the site, resulting in small gaps between containers and between containers and firewalls, sometimes less than 2 meters. Forklift machinery is generally longer than it is wide (length refers to the distance from the back of the forklift to the front of the fork arm, and width refers to the distance between the left and right sides of the forklift), and its minimum operating radius is ≥2.0 meters. If the site space is confined and there is insufficient adjustment and turning space for the forklift machinery (gap between containers and between containers and firewalls <2.0 meters), the forklift machinery cannot lift the battery pack to a suitable position perpendicular to the container, making operation impossible. Similarly, due to terrain limitations, the ground for construction may be gently sloping, forming an angle between the road surface and the container mounting surface. When the forklift machinery lifts the battery pack to a suitable height perpendicular to the container, there is a torsional angle between the product and the slot, again making operation impossible.

[0005] Therefore, it is necessary to develop a disassembly tool for large energy storage battery packs that is suitable for narrow spaces and sloping work surfaces, in order to overcome the shortcomings in current practical applications. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model proposes a disassembly fixture for large energy storage battery packs suitable for narrow spaces and sloping work surfaces. This fixture is less affected by the working environment and has a wider range of applications.

[0007] The technical solution of this utility model is implemented as follows:

[0008] A disassembly tooling for large energy storage battery packs suitable for confined spaces and sloping work surfaces, comprising:

[0009] Battery pack tray;

[0010] The lifting support tray includes a lifting support frame, the bottom surface of which is provided with a fork arm sleeve, and the battery pack support tray is located above the lifting support frame;

[0011] An angle adjustment structure is used to change the angle between the lifting support frame and the battery pack support tray;

[0012] A towing mechanism is provided, which is mounted on a lifting tray or a battery pack tray, and the towing direction of the towing mechanism is perpendicular to the length direction of the fork arm sleeve.

[0013] In a preferred embodiment, the angle adjustment structure includes a detachable hinge and a height-adjustable support assembly. One side of the battery pack tray is hinged to one side of the lifting support frame via the hinge, and the other side of the battery pack tray abuts against the other side of the lifting support frame via the support assembly.

[0014] In a preferred embodiment, the hinge and support assembly are located on two sides of the battery pack support tray that are perpendicular to the length direction of the fork sleeve.

[0015] In a preferred embodiment, the battery pack support tray includes a battery pack support frame. One side of the battery pack support frame is hinged to one side of the lifting support frame via a hinge, and the other side of the battery pack support frame abuts against the other side of the lifting support frame via a support assembly. Furthermore, the top surface of the battery pack support frame is provided with at least one roller frame, the length direction of which is parallel to the towing direction of the towing mechanism, and a plurality of rollers are arranged within the roller frame.

[0016] In a preferred embodiment, the battery pack support frame is also provided with multiple limiting mechanisms to restrict the horizontal movement freedom of the battery pack.

[0017] In a preferred embodiment, the limiting mechanism includes a stop, one end of which is used to abut against the battery pack and the other end of which is rotatably connected to the side of the battery pack support frame via a limiting bolt.

[0018] In a preferred embodiment, the hinge includes a first hinge leaf, a second hinge leaf, and a hinge shaft. The first hinge leaf and the second hinge leaf are fixedly connected to the lifting support bracket and the battery pack support bracket, respectively. The first hinge leaf has a first hinge hole, and the second hinge leaf has a second hinge hole. The first hinge hole and the second hinge hole are coaxially connected and both are rotatably sleeved on the outside of the hinge shaft. The length of the hinge shaft is greater than the sum of the lengths of the first hinge hole and the second hinge hole. The two ends of the hinge shaft are respectively provided with a limiting plate and a pin hole. A pin is detachably inserted into the pin hole. The diameters of the first hinge hole and the second hinge hole are both smaller than the outer diameter of the limiting plate and smaller than the length of the pin.

[0019] In a preferred embodiment, the support assembly includes at least one adjusting bolt. Both the lifting support bracket and the battery pack support bracket have at least one through hole. One end of the adjusting bolt is connected to the lifting support bracket or the battery pack support bracket, and the other end of the adjusting bolt is clearance-fitted with the through hole. Furthermore, one or more shims are fitted on the outer side of the adjusting bolt with clearance, and the shims are located between the lifting support bracket and the battery pack support bracket.

[0020] In a preferred embodiment, the towing mechanism includes an electric winch, a towing rope, and a chain. The electric winch is fixedly mounted on a lifting support or a battery pack support. One end of the towing rope is wound and connected to the electric winch, and the other end of the towing rope is connected to the middle of the chain. Both ends of the chain are provided with towing buckles for securing the battery pack with fixing lugs.

[0021] In a preferred embodiment, the battery pack support tray has side guards on both sides parallel to the towing direction of the towing mechanism.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] This invention features a battery pack support tray and a lifting tray. The battery pack support tray holds the battery pack, while the lifting tray is fitted onto the forks of the stacking machinery via a fork arm sleeve. When the forks of the stacking machinery are inserted into the fork arm sleeve and the entire tooling is raised, lowered, and moved to a suitable position, the battery pack can be pulled from the slot of the battery container onto the battery pack support tray via a towing mechanism, reducing manpower and labor intensity. Furthermore, for narrow spaces where the stacking machinery can enter but lacks sufficient adjustment and turning space, the towing direction of the towing mechanism is perpendicular to the length direction of the fork arm sleeve, i.e., the towing direction of the towing mechanism is perpendicular to the travel direction of the stacking machinery. When the stacking machinery travels to the position corresponding to the slot, there is no need to adjust the angle of the stacking machinery or turn it so that the forks are perpendicular to the container. This makes it suitable for narrow spaces and effectively reduces the impact of narrow spaces on battery pack disassembly operations. Furthermore, for sloping work surfaces with an angle between the road surface and the container mounting surface, an angle adjustment structure is set up to change the angle between the lifting support frame and the battery pack support tray. This ensures that the angle between the lifting support frame and the battery pack support tray matches the angle between the road surface and the container mounting surface, keeping the top surface of the battery pack support tray level and thus enabling the operation. This effectively reduces the impact of sloping work surfaces on battery pack disassembly operations. Therefore, this invention is suitable for narrow spaces and sloping work surfaces, is less affected by the working environment, and has a wider range of applications. Attached Figure Description

[0042] Please refer to Figures 1-7

[0043] A disassembly tooling for large energy storage battery packs suitable for confined spaces and sloping work surfaces, comprising:

[0044] Battery pack tray 1, used to support battery pack 100;

[0045] The lifting support tray 2 includes a lifting support frame 21, and a fork arm sleeve 22 is provided on the bottom surface of the lifting support frame 21. The battery pack support tray 1 is located above the lifting support frame 21.

[0046] The angle adjustment structure 3 is used to change the angle between the lifting support frame 21 and the battery pack support tray 1, thereby adjusting the angle between the lifting support frame 21 and the battery pack support tray 1 so that the top surface of the battery pack support tray 1 remains horizontal, thus enabling the operation and effectively reducing the impact of the slope operation on the battery pack disassembly operation.

[0047] The towing mechanism 4 is mounted on the lifting pallet 2 or the battery pack pallet 1. The towing direction of the towing mechanism 4 is perpendicular to the length direction of the fork arm sleeve 22. In other words, the towing direction of the towing mechanism 4 is perpendicular to the travel direction of the stacking machinery 200. Therefore, when the stacking machinery 200 travels to the position corresponding to the slot, there is no need to adjust the angle of the stacking machinery 200 or turn it so that the fork arm is perpendicular to the direction of the container. This makes it suitable for narrow spaces and effectively reduces the impact of narrow spaces on battery pack disassembly operations.

[0048] In some preferred embodiments, there are two fork arm sleeves 22, which are parallel to each other and fixedly connected to the battery pack tray 1 by welding, riveting, or bolting, and can be fitted onto the two forks of the stacking machinery 200 with a gap. It is understood that the fork arm sleeves 22 can also be used with various types of stacking machinery, lifting machinery, or forklifts for operation, and can be matched as needed according to the construction environment and equipment options. In addition, there can also be only one fork arm sleeve 22 to adapt to machinery with only one fork arm, such as a single-finger forklift.

[0049] Please refer to Figure 2 and Figure 3 The angle adjustment structure 3 includes a detachable hinge 31 and a height-adjustable support assembly 32. One side of the battery pack tray 1 is hinged to one side of the lifting support frame 21 via the hinge 31, and the other side of the battery pack tray 1 abuts against the other side of the lifting support frame 21 via the support assembly 32. The battery pack tray 1 can rotate relative to the lifting support frame 21 around the hinge 31, changing the angle between the battery pack tray 1 and the lifting support frame 21. The support assembly 32 holds the end of the battery pack tray 1 away from the hinge 31, thereby fixing the angle between the battery pack tray 1 and the lifting support frame 21.

[0050] In some optional embodiments, both sides of the battery pack tray 1 are hinged to both sides of the lifting support frame 21 via hinges 31. At the same time, both sides of the battery pack tray 1 abut against both sides of the lifting support frame 21 via support components 32. Thus, when working on a slope, the hinge 31 on the lower side can be removed, allowing the battery pack tray 1 to rotate around the hinge 31 on the higher side as a pivot, thereby better adapting to the inclination direction of the slope.

[0051] In an optional embodiment, the hinge 31 and the support assembly 32 are respectively located on both sides of the battery pack support tray 1 that are perpendicular to the length direction of the fork sleeve 22. That is, the plane at which the angle between the battery pack support tray 1 and the lifting support frame 21 is located is parallel to the vertical plane at which the length direction of the fork sleeve 22 is located. This design is suitable for stacking machinery 200 to be in an upward or upwardly inclined slope working surface.

[0052] In another alternative embodiment, the hinge 31 and the support assembly 32 are respectively located on both sides of the battery pack support tray 1 that are parallel to the length direction of the fork sleeve 22. That is, the plane where the angle between the battery pack support tray 1 and the lifting support frame 21 is located is parallel to the vertical plane where the towing direction of the towing mechanism 4 is located. This design is suitable for stacking machinery 200 to be on a sloping working surface that is inclined to the left or right.

[0053] Please refer to Figures 2-4 The battery pack support tray 1 includes a battery pack support frame 11. One side of the battery pack support frame 11 is hinged to one side of the lifting support frame 21 via a hinge 31. The other side of the battery pack support frame 11 is abutted against the other side of the lifting support frame 21 via a support assembly 32. That is to say, on the sloping working surface, the included angle between the battery pack support frame 11 and the lifting support frame 21 can be adjusted by the angle adjustment structure 3 so that the top surface of the battery pack support frame 11 remains horizontal.

[0054] In some preferred embodiments, the top surface of the battery pack support frame 11 is provided with at least one roller frame 12, the length direction of the roller frame 12 is parallel to the dragging direction of the dragging mechanism 4, and a plurality of rollers 13 are arranged in the roller frame 12.

[0055] The rollers 13 are rotatably mounted on the roller frame 12 via bearings. In use, the dragging mechanism 4 drags the battery pack 100 onto the plane formed by the multiple rollers 13. The rolling friction reduces the movement resistance of the battery pack 100. In addition, high-viscosity grease can be applied to the rollers 13 to further reduce the coefficient of friction.

[0056] In some preferred embodiments, the battery pack support frame 11 is also provided with a plurality of limiting mechanisms 5 for limiting the horizontal movement freedom of the battery pack 100.

[0057] Furthermore, each of the aforementioned limiting mechanisms 5 is divided into two groups, with the two groups of limiting mechanisms 5 respectively disposed on both sides of the battery pack support 11 perpendicular to the arrangement direction of the rollers 13. When the battery pack 100 is dragged onto the battery pack support 11, the two groups of limiting mechanisms 5 respectively block the two sides of the battery pack 100 perpendicular to the arrangement direction of the rollers 13, preventing the battery pack 100 from moving along the arrangement direction of the rollers 13 unplanned, and effectively preventing the battery pack 100 from falling when the stacking machinery 200 lifts, lowers, or moves the battery pack 100.

[0058] Please refer to Figure 2 and Figure 4 The limiting mechanism 5 includes a stop 51, one end of which is used to abut against the battery pack 100 and the other end of which is rotatably connected to the side of the battery pack support frame 11 via a limiting bolt 52.

[0059] In this specific embodiment, the distance from the end of the stop block 51 away from the limiting bolt 52 to the limiting bolt 52 is greater than the distance from the top surface of the battery pack support tray 1 to the limiting bolt 52. By turning the limiting bolt 52 counterclockwise, the stop block 51 can be loosened and rotated so that the end of the stop block 51 away from the limiting bolt 52 extends above the top surface of the battery pack support tray 1. Then, by turning the limiting bolt 52 clockwise, the stop block 51 is tightly fixed to the side of the battery pack support bracket 11, which keeps the end of the stop block 51 away from the limiting bolt 52 extending above the top surface of the battery pack support tray 1, thereby blocking and preventing the battery pack 100. Similarly, by loosening and rotating the stop block 51 so that the end away from the limiting bolt 52 rotates and falls below the top surface of the battery pack support tray 1, the stop block 51 cannot contact the battery pack 100, thus not affecting the movement of the battery pack 100 on the battery pack support tray 1.

[0060] Please refer to Figure 5The hinge 31 includes a first hinge 311, a second hinge 312, and a hinge shaft 313. The first hinge 311 and the second hinge 312 are fixedly connected to the lifting support frame 21 and the battery pack support frame 11, respectively. The first hinge 311 is provided with a first hinge hole, and the second hinge 312 is provided with a second hinge hole. The first hinge hole and the second hinge hole are coaxially connected and both are rotatably sleeved on the outside of the hinge shaft 313. The length of the hinge shaft 313 is greater than the sum of the lengths of the first hinge hole and the second hinge hole. The two ends of the hinge shaft 313 are respectively provided with a limiting plate 314 and a pin hole 315. A pin (not shown) can be detachably inserted into the pin hole 315. The diameters of the first hinge hole and the second hinge hole are both smaller than the outer diameter of the limiting plate 314 and smaller than the length of the pin, thereby restricting the axial movement freedom of the hinge shaft 313 through the limiting plate 314 and the pin. When working on a slope, the pin on the hinge 31 on the lower side is pulled out of the pin hole 315, and then the hinge shaft 313 is pulled out from the first hinge hole and the second hinge hole, thereby separating the first hinge 311 and the second hinge 312. At the same time, the battery pack support 11 and the lifting support 21 on the lower side can be separated. At this time, the battery pack support tray 1 can be flipped with the hinge shaft 313 on the hinge 31 on the higher side as the rotation axis, and the included angle between the battery pack support 11 and the lifting support 21 can be adjusted.

[0061] It is understood that the hinge 31 may also adopt other existing detachable hinge structures, such as a quick-release hinge (application number CN202122082520.X), a detachable hinge (application number CN201520747058.2), etc.

[0062] Please refer to Figure 3 , Figure 4 and Figure 6 The support assembly 32 includes at least one adjusting bolt 321. Both the lifting support frame 21 and the battery pack support frame 11 are provided with at least one through hole 323. The number of through holes 323 is twice the number of adjusting bolts 321. One end of the adjusting bolt 321 is connected to the lifting support frame 21 or the battery pack support frame 11, and the other end of the adjusting bolt 321 is clearance-fitted with the through hole 323. Furthermore, one or more gaskets 322 are sleeved on the outer side of the adjusting bolt 321, and the gaskets 322 are located between the lifting support frame 21 and the battery pack support frame 11.

[0063] In this specific embodiment, the diameter of the through hole 323 is smaller than the outer diameter of the head of the adjusting bolt 321 and larger than the outer diameter of the shank of the adjusting bolt 321. Therefore, when the head of the adjusting bolt 321 is above the through hole 323 on the battery pack support bracket 11, the adjusting bolt 321 will not fall off under the action of gravity and its shank can pass through the through hole 323 on the battery pack support bracket 11 and the lifting support bracket 21 from top to bottom.

[0064] When in use, according to the required adjustment angle, one or more shims 322 are sequentially placed on the rod of the adjusting bolt 321. The two ends of the stacked shims 322 abut against the battery pack support bracket 11 and the lifting support bracket 21 respectively, until the top surface of the battery pack support tray 1 is horizontal.

[0065] Please refer to Figure 7 In some optional embodiments, the shank of the adjusting bolt 321 passes through the through holes 323 on the battery pack support 11 and the lifting support 21 in sequence with gaps, and is then threadedly connected to a nut with an outer diameter larger than that of the through hole 323, thereby forming a bolt-nut structure. This structure can prevent the adjusting bolt 321 from coming out of the through hole 323 unintentionally. When it is necessary to adjust the angle between the battery pack support 11 and the lifting support 21, the nut can be unscrewed from the adjusting bolt 321 without affecting the insertion or removal of the washer 322 from the shank of the adjusting bolt 321.

[0066] Please refer to Figures 2-4 The towing mechanism 4 includes an electric hinge 41, a towing rope 42, and a chain 43. The electric hinge 41 is fixedly mounted on the lifting support frame 21 or the battery pack support frame 11. One end of the towing rope 42 is wound and connected to the electric hinge 41, and the other end of the towing rope 42 is connected to the middle of the chain 43. Both ends of the chain 43 are provided with drag buckles 44 for securing the fixing ears of the battery pack 100. In use, the two drag buckles 44 are used to secure the two fixing ears of the battery pack 100 respectively. The electric hinge 41 is then activated, and the towing rope 42 is wound more and more around the electric hinge 41, thereby allowing the battery pack 100 to be pulled out of the slot in sequence through the electric hinge 41, the towing rope 42, the chain 43, and the drag buckles 44.

[0067] In some preferred embodiments, the tow rope 42 is a steel wire rope, and the electric winch 41 is fixedly mounted on the battery pack support frame 11.

[0068] In some preferred embodiments, the battery pack tray 1 is provided with baffles 111 on both sides parallel to the dragging direction of the dragging mechanism 4. The baffles 111 are integrally formed with one side of the roller frame 12 to prevent the battery pack 100 from falling off from both sides of the dragging direction of the dragging mechanism 4.

[0069] Working principle:

[0070] During the disassembly of the battery pack 100, the tooling of this utility model is fitted onto the fork arm of the stacker 200 via the fork arm sleeve 22. At this time, the dragging direction of the dragging mechanism 4 is perpendicular to the traveling direction of the stacker 200. When the stacker 200 enters a narrow space lacking sufficient adjustment position and turning space, and the working surface is a slope, the battery pack support tray 1 is first moved and raised by the stacker 200 to align with the slot where the battery pack 100 to be disassembled is located. Furthermore, the tooling of this utility model... The space between the battery pack support and the battery holder is filled with wooden blocks. Then, the pin on the hinge 31 on the lower side is pulled out of the pin hole 315, and the hinge pin 313 is pulled out of the first hinge hole and the second hinge hole. After the first hinge 311 and the second hinge 312 are separated, the battery pack support tray 1 is rotated around the hinge pin 313 on the hinge 31 on the higher side, changing the angle between the battery pack support frame 11 and the lifting support frame 21, so that the rod of the adjusting bolt 321 is disengaged from the battery pack support frame 1. 1. Lift the through hole 323 on the support bracket 21, then insert an appropriate number of shims 322 into the rod of the adjusting bolt 321 in sequence until the stacked shims 322 can support the battery pack support tray 1 to maintain a horizontal state. Then, rotate the stop block 51 on the side of the battery pack support tray 1 away from the battery pack 100 until its top extends above the top surface of the battery pack support tray 1 and tighten the limiting bolt 52. At the same time, use the two drag buckles 44 to hook the two fixing ears of the detachable battery pack 100 respectively and start the electric hinge. The electric hoist 41 sequentially pulls the battery pack 100 out of the slot and onto the roller 13 via the tow rope 42, chain 43, and tow buckle 44 until the battery pack 100 abuts against the end of the stop block 51 extending above the top surface of the battery pack support tray 1. This allows the battery pack 100 to be dragged onto the tooling of this invention without adjusting the angle or turning the stacking machinery 200, effectively ensuring the safe movement and landing of the battery pack 100 and facilitating subsequent opening and maintenance of the battery pack 100. Therefore, this invention is suitable for narrow spaces and sloping work surfaces, is less affected by the working environment, and has a wider range of applications.

[0071] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
