Description

Technical Field

[0001] This utility model relates to the field of battery module disassembly and assembly tooling technology, and in particular to a tooling that can be used to disassemble and assemble battery modules of energy storage systems. Background Technology

[0002] With the rapid development of new energy technologies, lithium battery energy storage systems have been widely used due to their high energy density and efficiency. The scale of energy storage systems is increasing daily, and non-walk-in prefabricated modules have become the mainstream deployment solution. At the same time, battery module technology has evolved from primarily air cooling to primarily liquid cooling, resulting in a significant increase in the weight of a single battery module, from tens of kilograms to the current 300 to 600 kilograms.

[0003] During the long-term operation of energy storage systems, battery modules may malfunction, requiring them to be removed from the prefabricated compartment for repair or replacement. However, the on-site disassembly and assembly of heavy-duty battery modules currently faces significant challenges. Due to their weight, which far exceeds the capabilities of manual labor, specialized tools or equipment are necessary.

[0004] Currently, the main method for replacing battery modules in the industry is using a forklift. The specific procedure is as follows: place the battery module on the forklift forks, and move the forklift to load it into the prefabricated battery compartment; when it needs to be removed, extend the forks into the bottom of the battery module inside the compartment, lift it, and move it out.

[0005] However, using forklifts for battery module installation and removal has the following drawbacks. For example, in situations where the maintenance space is small or the ground is uneven such as gravel, forklifts are not only difficult to enter and operate flexibly, but are therefore unsuitable for field environments with limited space and poor road conditions. Utility Model Content

[0046] To enable those skilled in the art to better understand the technical solutions in this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments in this utility model, and not all of the embodiments in this utility model.

[0047] Please refer to Figure 1-6 As shown, a tooling for assembling and disassembling battery modules of an energy storage system includes:

[0048] The system includes: a support frame 10; a lifting platform 20, which is slidably mounted on the support frame 10 along its height direction; a sliding mechanism 30, which is used to place the battery module 60 and is slidably mounted on the upper part of the lifting platform 20; a lifting mechanism 40, which is located between the support frame 10 and the lifting platform 20 and is used to drive the lifting platform 20 to slide up and down along its height direction; and a traction mechanism 50, which is used to traction the battery module 60 to move it out of the battery compartment and slide it into the lifting platform 20 with the sliding mechanism 30, or to traction the battery module 60 to slide out of the lifting platform 20 and move it into the battery compartment.

[0049] This embodiment uses a height-adjustable lifting platform 20 mounted on the support 10 to match the height of the battery module 60. The battery module 60 is then moved from the battery compartment to the sliding mechanism 30 of the lifting platform 20 via a traction mechanism 50 for disassembly. During installation, the battery module 60 is moved from the lifting platform 20 into the battery compartment via the traction mechanism 50 for installation. This fixture has a simple structure, is easy to operate, requires no large equipment operating space, and can be effectively applied to operation sites with limited space and uneven ground.

[0050] Please refer to Figure 1 and Figure 2 As shown, in this embodiment, the support 10 includes: a base frame 101, which is a rectangular frame; support rods 102, which are vertically fixed to the four corners of the rectangular frame; and connecting rods 103, which are horizontally fixed to the end of the adjacent support rod 102 away from the base frame 101. Sliding sleeves 104 are respectively provided at the four corners of the lifting platform 20. The sliding sleeves 104 are located outside the support rods 102 and have limiting holes. Limiting bolts 105 are rotatably installed within the limiting holes.

[0051] It should be noted that in this embodiment, the bracket 10 adopts a frame structure, the purpose of which is to provide movement space for the lifting platform 20 and the lifting mechanism 40. Specifically, the space enclosed by the adjacent support rods 102, connecting rods 103 and base frame 101 on both sides provides space for fixing and installing the lifting mechanism 40, and the space enclosed by the four support rods 102 provides installation space and vertical sliding space for the lifting platform 20.

[0052] For ease of installation, the brackets 10 in this embodiment are all made of square tubes, and the sliding sleeves 104 have square cavities adapted to the square tubes. Meanwhile, to improve the adaptability of the tooling, the brackets 10 can be detachable, allowing for easy expansion of the tooling's width and / or height as needed.

[0053] To facilitate the fixation of the bracket 10, a fixing hole is provided on the upper part of the support rod 102 near the insertion pulley 501 in this embodiment, and it is fixed to the battery cluster rack in the battery compartment by a fixing rope. In this way, the bracket 10 can be prevented from shaking or tipping over during the removal or installation of the battery module 60, which could cause damage to the battery module 60.

[0054] Please refer to Figure 4 As shown, the tooling in this embodiment also includes a height adjustment component 70. The height adjustment component 70 includes nuts 701 fixedly disposed at the four corners of the base frame 101, bolts 702 adapted to the nuts 701 and vertically rotatably disposed at the four corners of the base frame 101, and pads 703 disposed at the lower part of the bolts 702.

[0055] Understandably, when the bottom surface of the tooling's operating area is uneven, the lifting platform 20 may not be able to make parallel contact with the battery module 60, making it inconvenient for workers to move the battery module 60 into or out of the battery compartment. Specifically, when it is necessary to adjust the height of a certain corner of the tooling, the operator uses tools or manually rotates bolt 702. Rotating bolt 702 clockwise causes it to unscrew downwards in the fixed nut 701, pushing the pad 703 to contact the ground, thereby lifting that side of the tooling and increasing the height of that corner. Rotating bolt 702 counterclockwise causes it to screw upwards, and the height of that corner decreases under the weight of the tooling itself. By adjusting the extension length of one or more bolts 702, the entire tooling can be kept horizontal and vertical on uneven ground (such as gravel ground or slopes). This allows it to adapt to various complex terrains, ensuring that its main frame always remains vertical, providing a foundation for the safe and stable operation of the lifting platform 20. This also facilitates the precise alignment of the lifting platform 20, allowing the battery module 60 to be moved in and out smoothly and without bumps.

[0056] Please refer to Figure 2 and Figure 3 As shown, the sliding mechanism 30 includes: a slide rail 301, which is symmetrically arranged on the upper part of the lifting platform 20 along the moving direction of the battery module 60; and a slider 302, which is slidably arranged on the slide rail 301, with the height of the slider 302 on the same slide rail 301 increasing sequentially along the direction in which the battery module 60 moves out of the battery compartment.

[0057] It should be noted that in this example, the slide rail 301 is a linear slide rail 301, and the slider 302 and the slide rail 301 adopt rolling friction to reduce the friction between them.

[0058] Meanwhile, in this embodiment, the height of the sliders 302 on the same slide rail 301 increases sequentially, thereby forming a micro-slope on the sliders 302 on the same slide rail 301, which is beneficial for the battery module 60 to be moved out and into the battery compartment.

[0059] Specifically, when the battery module 60 is removed, the battery module 60 first contacts the highest slider 302. Under the traction of the traction mechanism 50, as the highest slider 302 moves on the slide rail 301, the battery module 60 contacts the sliders 302 with decreasing height in sequence during the movement, until the battery module 60 is completely removed from the battery compartment and falls onto the slider 302.

[0060] When the battery module 60 is moved into the battery compartment, under the traction of the traction mechanism 50, the battery module 60 first enters the battery compartment from the lowest slide rail 301. During the movement, the battery module 60 separates from the slider 302, which has a gradually increasing height, until the battery module 60 is completely inside the battery compartment.

[0061] In this embodiment, the height of the slider 302 can be achieved by setting pads 303 of different thicknesses on the upper part of the slider 302, or by directly selecting a slider 302 with gradually changing height.

[0062] Please refer to Figure 2 As shown, in this embodiment, the lifting mechanism 40 is a manual hoist symmetrically arranged on both sides of the support 10. The manual hoist includes a housing 401, an upper hook 402 disposed on the upper part of the housing 401, a lifting chain 403 rotatably wound around the housing 401, a connecting chain 404 connected to the lower part of the lifting chain 403, and a hand chain 405 rotatably connected to the housing 401 to provide driving force. The upper hook 402 is fixed to the upper part of the support 10, the lower part of the lifting chain 403 is connected to the middle part of the connecting chain 404, and the two ends of the connecting chain 404 are respectively connected to the two ends of the lifting platform 20.

[0063] It is understood that in this embodiment, the connecting chain 404 forms a stable four-point lifting structure between the manual hoists on both sides and the lifting platform 20, which can ensure the smoothness of the lifting platform 20 during the lifting process. The aforementioned sliding sleeve 104 provides a guiding function for the lifting of the lifting platform 20, preventing the lifting platform 20 from sliding or twisting during the lifting process.

[0064] It should be noted that, as manual hoists are existing technology, this embodiment only describes the structure of the manual hoist that directly contacts and connects with the tooling. Other structures of the manual hoist, such as the sprocket, sprocket box, and braking structure, are not described in detail. Obviously, the manual hoist in this embodiment can also be replaced by an electric hoist or other types of lifting mechanisms 40, and this application does not limit this.

[0065] Please refer to Figure 5 and Figure 6 As shown, in this embodiment, the traction mechanism 50 includes: an insertion pulley 501, fixed to one end of the lifting platform 20 along its length; an exit pulley 502, movably hung in the disassembly hole 601 at the front end of the battery module 60; and a traction rope 503, wound around the insertion pulley 501 or the exit pulley 502, with the fixed end of the traction rope 503 fixed to the disassembly hole 601 of the battery module 60 or fixed to one end of the lifting platform 20 away from the insertion pulley 501.

[0066] It should be noted that in this embodiment, by setting the insertion pulley 501 and the removal pulley 502, and cooperating with different winding methods of the traction rope 503, the battery module 60 is moved into or out of the battery compartment by the traction rope 503 and the insertion pulley 501 and the removal pulley 502.

[0067] Specifically, such as Figure 5As shown, when it is necessary to remove the battery module 60 from the battery compartment, the tooling is moved to the front of the battery module 60 to be removed, and the relative position of the pad 703 is adjusted by rotating the bolt 702 as needed to keep the tooling vertical.

[0068] Pull the manual hoists on both sides simultaneously to raise the lifting platform 20 until the highest slider 302 is level with the bottom of the battery module 60. Tighten the limit bolts 105 to fix the lifting platform 20. At the same time, fix the tooling to the battery cluster rack in the battery compartment with the fixing rope.

[0069] Move slider 302 to the end near battery module 60, and simultaneously hook pulley 502 onto the disassembly hole 601 at the front of battery module 60. Fix traction rope 503 to the end of lifting platform 20 away from pulley 501. Wrap the free end of traction rope 503 around pulley 502. Manually pull traction rope 503 to gradually move battery module 60 out of battery compartment until it is completely on slider 302. Continue pulling traction rope 503 until battery module 60 is completely within lifting platform. Loosen limit bolt 105 and pull manual hoist to lower lifting platform 20 to a height suitable for operation.

[0070] like Figure 6 As shown, when it is necessary to move the battery module 60 from the lifting platform 20 into the battery compartment, the tooling is moved to the front of the battery module 60 placement position. The relative position of the pad 703 is adjusted by rotating the bolt 702 as needed to keep the tooling vertical. At the same time, the tooling is fixed to the battery cluster rack in the battery compartment by fixing ropes.

[0071] Pull the manual hoists on both sides simultaneously to lower the lifting platform 20 to the appropriate position and place the battery module 60 on the lifting platform 20.

[0072] The fixed end of the traction rope 503 is fixed to the disassembly hole 601 of the battery module 60, the free end passes through the bottom of the battery module 60 and is wound around the insertion pulley 501, and the free end passes through the lower part of the lifting platform 20 to the end of the bracket 10 away from the battery compartment.

[0073] Then, simultaneously pull the manual hoists on both sides to raise the lifting platform 20 until the lowest slider 302 is flush with the bottom of the battery module 60, and tighten the limit bolts 105 to fix the lifting platform 20.

[0074] Manually pull the traction rope 503 to pull the battery module 60 out of the lifting platform 20 and down to the battery cluster rack in the battery compartment. Continue to pull the traction rope 503 until the battery module 60 is completely moved into the battery compartment.

[0075] The above description is a specific implementation of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the scope of protection of this application.
