[0033] In the current technology, with the continuous development of electrification, electric construction machinery is receiving increasing attention from the market. Existing construction machinery typically uses a hoisting method for battery swapping, which requires welding a lifting lug onto each battery pack for hoisting. However, the welded hook not only increases the weight of the battery pack but also needs to consider its impact on the overall structure of the battery pack; therefore, improvement is necessary.

[0034] To overcome the shortcomings of the prior art, this application provides a lifting lug with a mounting plate for detachably fixed connection to the equipment to be lifted. When the mounting plate is fixed to the equipment to be lifted, a lifting gap is formed between the lifting plate and the equipment to be lifted to allow the hook to pass through. In this way, the hook of the lifting device can extend into the lifting gap, and the lifting plate can act as a load-bearing component to lift the equipment to be lifted. This method eliminates the need to design a lifting lug for each piece of equipment to be lifted, reduces the weight of the equipment to be lifted, and avoids the impact of the hook on the equipment to be lifted.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will be combined with the embodiments of this application. Figures 1 to 4The technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] This application provides a lifting lug 10. In some embodiments, the lifting lug 10 includes a mounting plate 100, a connecting plate 200, and a lifting plate 300. The mounting plate 100 is used for detachably fixed connection to the equipment to be lifted. The connecting plate 200 is connected to the mounting plate 100. One end of the lifting plate 300 is formed in the connecting plate 200 and extends in a direction away from the mounting plate 100. When the mounting plate 100 is fixed to the equipment to be lifted, a lifting gap is formed between the lifting plate 300 and the equipment to be lifted for the passage of the hook 20.

[0037] In this embodiment, the mounting plate 100 is used to be detachably fixedly connected to the equipment to be lifted. When the mounting plate 100 is fixed to the equipment to be lifted, a hanging gap is formed between the lifting plate 300 and the equipment to be lifted to allow the hook 20 to pass through. In this way, the hook 20 of the lifting device can be inserted into the hanging gap, and the lifting plate 300 can serve as a force-bearing component to lift the equipment to be lifted upward.

[0038] In this embodiment, since the lifting lug 10 is detachably connected to the equipment to be lifted via the mounting plate 100, when the equipment to be lifted needs to be lifted, the lifting gear can be installed on-site first, then the lifting operation can be carried out, and finally the lifting lug 10 can be removed after the lifting is completed. This method eliminates the need to design a lifting lug 10 for each piece of equipment to be lifted, reduces the weight of the equipment to be lifted, and avoids the impact of the hook 20 on the equipment to be lifted.

[0039] Specifically, the lifting lug 10 can be used in the lifting operations of battery packs on construction machinery. When it is necessary to replace the battery pack, the lifting lug 10 can be installed at the corresponding position on the battery pack according to the number and position of the lifting hooks 20 of the lifting equipment. Specifically, it can be fixedly connected to the top wall of the battery pack through the mounting plate 100, forming a lifting gap. After the lifting operation is completed, the lifting lug 10 is removed, which reduces the weight of the battery pack, and the lifting lug 10 will not occupy the internal space of the battery pack or protrude from the surface of the battery pack, thus avoiding increasing design complexity.

[0040] In some embodiments, the mounting plate 100, connecting plate 200, and lifting plate 300 may be integrally formed. The overall material may be cast aluminum, which is lightweight, high-strength, easy to disassemble, and helps ensure safety during lifting.

[0041] In some embodiments, the mounting plate 100 and the connecting plate 200 are connected by an arc, and the thickness of the middle part of the arc is greater than the thickness of the mounting plate 100 or the connecting plate 200. That is, the connection between the two is thickened, which enhances the stability of the mounting plate 100 and the connecting plate 200.

[0042] In some embodiments, the lifting lug 10 may further include a plurality of reinforcing plates 400, which are located on the side of the connecting plate 200 facing the mounting plate 100. The plurality of reinforcing plates 400 are arranged at intervals, and each reinforcing plate 400 has a first edge 410 and a second edge 420. The first edge 410 is connected to the mounting plate 100, and the second edge 420 is connected to the connecting plate 200.

[0043] In this embodiment, the connecting plate 200 is connected to the mounting plate 100. The connecting plate 200 and the mounting plate 100 are not on the same plane, but can be at a certain angle (e.g., 90°). The reinforcing plate 400 is located on the side of the connecting plate 200 facing the mounting plate 100. That is, the reinforcing plate 400 and the mounting plate 100 are on the same side of the connecting plate 200, while the reinforcing plate 400 and the lifting plate 300 are on different sides of the connecting plate 200.

[0044] With this configuration, when the lifting plate 300 is subjected to an upward external force during lifting, the lifting plate 300 will press the connecting plate 200 towards the mounting plate 100. The reinforcing plate 400 is located on the side of the connecting plate 200 facing the mounting plate 100. The first edge 410 of the reinforcing plate 400 is connected to the mounting plate 100, and the second edge 420 of the reinforcing plate 400 is connected to the connecting plate 200. The reinforcing plate 400 can effectively support the connecting plate 200, prevent the connecting plate 200 from tilting towards the mounting plate 100, and thus prevent the entire lifting lug 10 from deforming.

[0045] In this embodiment, there are multiple reinforcing plates 400, which are arranged at intervals. This allows for the specific placement of the multiple reinforcing plates 400 according to the position of the lifting plate 300, providing high flexibility.

[0046] In some specific embodiments, the mounting plate 100, connecting plate 200, lifting plate 300 and multiple reinforcing plates 400 can be integrally formed cast aluminum parts. Cast aluminum parts are lightweight and have high strength, which is beneficial for disassembly and ensures safety during hoisting.

[0047] Furthermore, each reinforcing plate 400 has a third edge 430 connecting the first edge 410 and the second edge 420, and at least a portion of the third edge 430 is configured as an arc shape recessed inward therein.

[0048] In this embodiment, the third edge 430 is designed as an arc shape, which makes the transmission of force lines smoother and more continuous. The arc provides a gradual geometry, allowing the force to gradually transition from one area to another, rather than changing abruptly at a specific point. This avoids the concentration and distortion of force lines, effectively reduces the degree of stress concentration, and further improves the stress reliability of the lifting lug 10.

[0049] In some embodiments, the mounting plate 100 is provided with a mounting portion 110 for fixed connection with the equipment to be lifted.

[0050] In some specific embodiments, the mounting portion 110 may be a mounting hole. The equipment to be lifted can be detachably connected to the mounting plate 100 via fasteners passing through the mounting hole.

[0051] Of course, those skilled in the art can also use other forms of mounting parts 110 to achieve a fixed connection between the mounting plate 100 and the equipment to be lifted, such as clamps, buckles, etc.

[0052] In some embodiments, the mounting plate 100 is provided with a positioning part 120 for pre-positioning with the equipment to be lifted.

[0053] In some specific embodiments, the positioning part 120 can be a positioning hole, and the equipment to be lifted can be pre-positioned and connected to the lifting lug 10 through the positioning post passing through the positioning hole.

[0054] Of course, those skilled in the art can also use other forms of positioning part 120 to achieve pre-positioning of the mounting plate 100 and the equipment to be lifted, such as positioning protrusion, positioning groove, etc.

[0055] In some embodiments, the lifting lug 10 may further include two flanges 500 and a plurality of reinforcing ribs 510. The two flanges 500 are respectively formed on both sides of the lifting plate 300 in the width direction, and the end of each flange 500 is connected to the connecting plate 200. The plurality of reinforcing ribs 510 are arranged at intervals along the length direction of the lifting plate 300, and each reinforcing rib 510 is connected to the lifting plate 300. The two ends of each reinforcing rib 510 are respectively connected to the two flanges 500.

[0056] In this embodiment, the end of each flange 500 near the connecting plate 200 is formed on the surface of the connecting plate 200, so that two flanges 500 are connected to the lifting plate 300 and the connecting plate 200 at the same time, thereby improving the fixing effect between the lifting plate 300 and the connecting plate 200.

[0057] In addition, two flanges 500 are formed on both sides of the lifting plate 300 in the width direction and extend upward to form a U-shaped cross section. Multiple reinforcing ribs 510 are formed in the U-shaped groove, which increases the fixing effect between the flanges 500 and the lifting plate 300.

[0058] Furthermore, multiple reinforcing ribs 510 can be arranged along the length of the lifting plate 300 according to specific circumstances.

[0059] In some specific embodiments, multiple reinforcing ribs 510 can be evenly arranged along the length of the lifting plate 300, so that the multiple reinforcing ribs 510 can evenly bear the force on the lifting plate 300 and improve stability.

[0060] In some specific embodiments, the multiple reinforcing ribs 510 are also arranged at unequal intervals. Since the middle position of the lifting plate 300 generally bears greater force, the reinforcing ribs 510 in the middle position of the lifting plate 300 can be arranged more densely, while the reinforcing ribs 510 at both ends of the lifting plate 300 can be arranged more sparsely.

[0061] Furthermore, the sizes of the multiple reinforcing ribs 510 can be configured to be the same or different depending on the specific circumstances.

[0062] For example, the middle position of the lifting plate 300 generally bears a larger load, so the reinforcing rib 510 at the middle position of the lifting plate 300 can be set to be larger, while the reinforcing ribs 510 at both ends of the lifting plate 300 can be set to be smaller.

[0063] In some embodiments, the lifting lug 10 may further include an anti-slip portion 520, which is formed at the end of the lifting plate 300 away from the connecting plate 200 to prevent the hook 20 from slipping out of the hanging gap.

[0064] Since one end of the lifting plate 300 is connected to the connecting plate 200, while the other end is a free end, there is a risk of slippage and disengagement when the hook 20 acts on the bottom of the lifting plate 300 during lifting.

[0065] In this embodiment, the anti-detachment part 520 is formed at the end of the lifting plate 300 away from the connecting plate 200, which can stop the hook 20 and improve the safety during lifting.

[0066] In some embodiments, the lifting plate 300 is provided with a plurality of drainage holes 310 for drainage.

[0067] Since each reinforcing rib 510 is located between two flanges 500, the multiple reinforcing ribs 510 are divided into multiple small grooves along the extension direction of the lifting plate 300, which is not conducive to drainage.

[0068] In this embodiment, the lifting plate 300 is provided with a plurality of drainage holes 310 for drainage. In this way, rainwater and other liquids that collect in the small trough can be discharged through the drainage holes 310, thus preventing the liquid from accumulating in the lifting plate 300. On the one hand, this reduces the corrosion of the lifting plate 300 by these liquids, and on the other hand, it reduces the impact of these liquids on the lifting operation.

[0069] In some embodiments, the lateral width of the lifting plate 300 is set to be smaller than the lateral width of the connecting plate 200.

[0070] In this embodiment, the lateral width of the lifting plate 300 is set to be smaller than the lateral width of the connecting plate 200. That is, the lifting plate 300 will not occupy all the lateral space of the connecting plate 200 in the lateral direction. In this way, the surface of the connecting plate 200 not occupied by the lifting plate 300 can be used as the limiting surface 210 to limit the position of the hook 20.

[0071] In some embodiments, the lifting lug 10 may further include a limiting plate 600, which is formed on one side of the connecting plate 200 and is coplanar with the connecting plate 200, and is used to limit the position of the lifting hook 20.

[0072] In this embodiment, the limiting plate 600 is formed on one side of the connecting plate 200 and is coplanar with the connecting plate 200. In this way, the surface of the limiting plate 600 facing the lifting plate 300 can serve as the limiting surface 210 to limit the position of the hook 20.

[0073] See Figure 5 This application also provides a lifting device for suspending a battery pack, which may include the lifting lug 10 in any of the above embodiments.

[0074] The hoisting equipment described in this application can be used to hoist battery packs. In some specific embodiments, the battery may include a bottom module 30 and multiple battery modules 40, which are stacked on the bottom module 30. A fixing post 50 is provided at each of the four corners of the bottom module 30, and a fixing hole is provided at each of the four corners of each battery module 40. Each battery module 40 is fixed by the fixing post 50 passing through the fixing hole.

[0075] Furthermore, the fixing post 50 can extend through the top-level battery module 40. The lifting device has four lifting lugs 10, each of which is threadedly connected to the fixing post 50 through mounting holes 110 to secure the lifting lug 10 to the top layer of the battery pack.

[0076] The lifting equipment has four hooks 20, each hook 20 corresponding to a lifting lug 10. During lifting, each hook 20 extends into the bottom of the lifting plate 300 of the lifting lug 10 to lift the entire battery pack upward.
