Description

Technical Field

[0001] This utility model relates to hoisting fixtures, and more particularly to a hoisting device for energy storage battery modules. Background Technology

[0002] With the rapid development of the new energy industry, energy storage battery systems, as key equipment for energy storage and conversion, are facing increasingly stringent safety requirements during their manufacturing process. On the production and assembly line of energy storage battery packs, module hoisting is one of the critical technological steps, and the safety and reliability of its operation directly affect product quality, production efficiency, and the personal safety of workers.

[0003] The modular hoisting methods commonly used in the industry currently suffer from the following technical defects:

[0004] Traditional lifting fixtures typically employ simple hooks or clamping structures, lacking effective anti-sway designs. During lifting, the modules are prone to swaying or rotating due to the starting, stopping, and turning movements of overhead cranes or forklifts, causing the hooks to loosen or even detach from the module. This unstable lifting condition not only affects positioning accuracy but may also damage the module's outer casing due to collisions or friction, increasing safety risks.

[0005] The size and structure of energy storage battery modules vary significantly depending on the application scenario, but existing lifting fixtures are mostly fixed designs, only suitable for specific module models. When different specifications of modules need to be replaced on the production line, the lifting fixtures often need to be changed or adjusted, which not only reduces production efficiency but also increases equipment management costs. Although some fixtures are adjustable, the adjustment methods are complex and inconvenient to operate, making it difficult to meet the needs of rapid model changeover.

[0006] Currently, most hoisting fixtures rely solely on mechanical hooks or electromagnetic chucks to secure modules. In the event of a sudden power outage, mechanical failure, or operational error, the module may detach instantly. Furthermore, some fixtures' locking mechanisms depend on manual operation. If not fully locked, vibration or impact during hoisting may cause the module to slip off, posing a serious safety hazard.

[0007] In actual production, energy storage battery modules are typically heavy (generally ranging from 50-200 kg) and have a sophisticated structure. They also contain a large number of flammable and explosive battery cells. If they fall or collide during hoisting, in addition to direct economic losses, they may also cause secondary accidents such as fires and explosions. Existing hoisting solutions often fail to meet the stringent safety requirements of the energy storage industry, necessitating a new type of dedicated hoisting device. Utility Model Content

[0008] To address the shortcomings of the aforementioned technologies, this utility model provides an energy storage battery module hoisting device.

[0009] To solve the above technical problems, the technical solution adopted by this utility model is: an energy storage battery module hoisting device, including a structural square tube, on which multiple upper lifting rings and multiple lower lifting rings are threadedly connected;

[0010] Each lower ring is independently and detachably connected to the lifting rope via a spring buckle, and the lower end of the lifting rope is connected to a hook;

[0011] It also includes a horizontally oriented balance beam, which is fixedly connected to at least two hooks located on the same straight line, with a limit block wrapped around the hook shank of each hook.

[0012] Furthermore, the structural square tube includes two parallel horizontal beams, several longitudinal beams connected between the horizontal beams, upper lifting rings connected to the horizontal beams, and multiple upper and lower lifting rings symmetrically positioned relative to the midpoint of the horizontal beams.

[0013] Furthermore, positioning holes are provided on the crossbeam for the hooks to pass through in the vertical direction, and the number of positioning holes is matched with the number of hooks.

[0014] Furthermore, the upper lifting ring of each beam is located at the midpoint between two adjacent lower lifting rings.

[0015] Furthermore, the lower lifting ring is installed near the junction of the crossbeam and the longitudinal beam.

[0016] Furthermore, the lower end of the longitudinal beam located in the middle of the crossbeam has a reinforcing beam extending outward at both ends, and the reinforcing beam is connected to the lower lifting ring.

[0017] This utility model discloses a hoisting device for energy storage battery modules. It employs symmetrically distributed upper and lower lifting rings in conjunction with a rigid balance beam to form a stable force balance structure, reducing the module's sway amplitude from ±15° of traditional tooling to within ±5°, effectively preventing collision damage. Each lower lifting ring is connected to a lifting rope via an independent spring buckle, forming a six-point redundant hoisting system. Even if two non-adjacent lifting points fail, the remaining lifting points can still maintain a safety factor, completely eliminating the risk of single-point failure. The modular threaded connection design allows for rapid addition or removal of the number of lifting rings, and can be adjusted according to the length of the lifting rope, reducing changeover time to 3 minutes and increasing efficiency by 40%, meeting the hoisting needs of various modules weighing from 50-200kg. The symmetrical layout optimizes force distribution, reduces material redundancy, and lowers structural weight by 15%-20%. Simultaneously, the reinforced design of longitudinal beams and nodes ensures overall rigidity and extends service life. These innovative designs systematically solve the industry pain points of traditional tooling—"large sway, easy disengagement, and slow changeover"—and are particularly suitable for energy storage battery module hoisting scenarios with stringent safety and efficiency requirements.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] In this embodiment, Figure 1 and Figure 2 The energy storage battery module hoisting device shown includes a structural square tube 2, which serves as the core skeleton of the tooling. Through the high bending and torsional resistance of the square tube structure, it bears the entire weight of the module during hoisting. The main structure of the rigid square tube replaces the chain / rope, reducing swaying during hoisting. The structural square tube 2 is threaded with four upper lifting rings 1 and six lower lifting rings 3. The upper lifting rings 1 and lower lifting rings 3 are fixed through preset threaded holes. The number of threaded holes is unlimited, ensuring that the detachable threaded connection design supports the rapid addition or reduction of the number of lifting rings to adapt to different module specifications.

[0024] In this embodiment, the structural square tube 2 includes two parallel crossbeams 21, with upper lifting rings 1 connected to the crossbeams 21, and three longitudinal beams 22 connected between the crossbeams 21. The lower end of the longitudinal beam 22 located in the middle of the crossbeams 21 has reinforcing beams 23 extending outwards at both ends, which connect to lower lifting rings 3. The remaining lower lifting rings 3 are connected to the crossbeams 21. The upper lifting rings 1 and lower lifting rings 3 are symmetrical about the midpoint of the crossbeams 21. The four upper lifting rings 1 and six lower lifting rings 3 are axially symmetrically distributed with the midpoint of the longitudinal beams 22 in the middle of the crossbeams 21 as the center of symmetry. All lifting rings are symmetrically arranged with the midpoint of the central longitudinal beam as the center, ensuring that the weight of the module is evenly distributed to all stress points of the structural square tube, avoiding local stress concentration and significantly improving lifting stability. Specifically, if any one or two of the six lower lifting rings fail due to an accident, the remaining lifting rings can still maintain balance through symmetrical force. The lower lifting rings 3 connected to the reinforcing beam 23 are designed to overcome the problem of ordinary tooling lifting only from both sides of the module, which would cause the middle of the module to sag and deform easily. The reinforcing beam 23 extends horizontally from the midpoint of the longitudinal beam 22 to both sides to form a "cross" support structure. The lower lifting rings 3 connected to the extended end can hook the lifting lugs on the front and rear sides of the module, forming a four-sided lifting point layout together with the lower lifting rings 3 on the cross beam 21.

[0025] Each lower lifting ring 3 is independently and detachably connected to the lifting rope 5 via a spring buckle 4. When a single lifting rope 5 or hook 8 is damaged, it can be replaced simply by removing the corresponding spring buckle 4, without the need for overall machine shutdown for maintenance. Importantly, the presence of the spring buckle 4 allows for flexible replacement of the lifting rope 5 and hook 8, meeting various lifting scenarios such as modules and pallets.

[0026] like Figure 3 As shown, the lower end of the lifting rope 5 is connected to a hook 8, and a limit block 7 is wrapped around the hook shank of each hook 8. The limit block 7 adopts a U-shaped or ring structure to tightly wrap the hook shank (non-hook end) of the hook 8, forming a physical barrier. It is made of nylon or polyurethane material, which can prevent the hook 8 from directly colliding with the module shell and protect the surface coating of the module.

[0027] The energy storage battery module hoisting device also includes a balance beam 6 arranged in a horizontal direction. The balance beam 6 is fixedly connected to two hooks 8 located on the same straight line. The concept of the same straight line can be a straight line parallel to the front and rear end edges of the module, or a straight line parallel to the left and right end edges of the module. The balance beam 6 is provided with positioning holes for the hooks 8 to pass through in the vertical direction. The number of positioning holes matches the number of hooks 8.

[0028] The upper lifting ring 1 of each crossbeam 21 is located at the midpoint between two adjacent lower lifting rings 3, so that the tension of the lifting equipment is evenly transmitted to the lower lifting rings 3 on both sides through the upper lifting ring 1, avoiding the crossbeam 21 on one side bearing eccentric load. The lower lifting ring 3 is set near the joint between the crossbeam 21 and the longitudinal beam 22. The joint between the crossbeam 21 and the longitudinal beam 22 is a rigid node of the frame. Setting the lower lifting ring 3 here can directly utilize the high strength characteristics of the node and avoid deformation of the crossbeam mid-span area due to concentrated force.

[0029] In other embodiments, the reinforcing beam can be removed, and the lower lifting ring at the corresponding position is connected to the center position on the crossbeam, simplifying the structure.

[0030] This utility model significantly solves the core problems of traditional lifting fixtures through the following innovative designs, with specific advantages as follows: The symmetrically distributed upper and lower lifting rings work in conjunction with a rigid balance beam to form a stable force balance structure, reducing the module's swing amplitude from ±15° of traditional fixtures to within ±5°, effectively avoiding collision damage. Each lower lifting ring is connected to the lifting rope via an independent spring buckle, forming a six-point redundant lifting system. Even if two non-adjacent lifting points fail, the remaining lifting points can still maintain a safety factor, completely eliminating the risk of single-point failure. The modular threaded connection design supports rapid addition or removal of the number of lifting rings, and can be adjusted to match the length of the lifting rope, reducing changeover time to 3 minutes and increasing efficiency by 40%, meeting the lifting needs of various modules weighing from 50-200kg. The symmetrical layout optimizes force distribution, reduces material redundancy, and lowers structural weight by 15%-20%. Simultaneously, the reinforced design of longitudinal beams and nodes (such as welded triangular plates) ensures overall rigidity and extends service life. These innovative designs systematically address the industry pain points of traditional tooling, such as "large shaking, easy detachment, and slow changeover," and are particularly suitable for energy storage battery module hoisting scenarios with stringent safety and efficiency requirements.

[0031] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
