Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, and more specifically, to a battery lifting device. Background Technology

[0002] With the global energy structure transformation and the advancement of "dual-carbon" goals, the new energy vehicle market has entered a stage of rapid development. As a core component, the safe, efficient, and rapid installation, disassembly, and maintenance of batteries have become industry pain points. This is particularly true for new energy buses, where batteries are becoming larger, have higher energy density, and are more modularly integrated. Currently, battery installation and transportation typically rely on aerial transport, requiring high-altitude operations. This places higher demands on the safety of lifting equipment while simultaneously ensuring installation efficiency. Furthermore, most current battery installations are top-mounted, resulting in high battery density and limited operational space.

[0003] Currently, traditional lifting methods typically utilize the oblong holes on the side of the battery box for lifting. This involves inserting a pin into the oblong hole inside the battery box and rotating it 90 degrees to complete the lifting. However, this method often places the stress on the outer shell of the battery box, which is only 6mm in diameter. If the battery box tilts during lifting, the entire weight of the battery box will be on one side of the hook, often resulting in hook breakage. This poses a high safety risk and also has poor adaptability. Utility Model Content

[0027] Example

[0028] Combination Figures 1 to 5 As shown, this embodiment provides a battery lifting device, including a lifting frame, a lifting component connected to the lifting frame, and also includes multiple hooks 4 and limiting pins 5;

[0029] One end of the hook 4 is rotatably connected to the lifting frame, and the other end is provided with a support part 6 on its inner side. The upper surface of the support part 6 is a support surface 7, which is used to provide surface support for the bottom of the battery box. The other end of the hook 4 is provided with a limit groove 8 on its outer side.

[0030] The limiting pin 5 is rotatably connected to the hook 4, and has a limiting part 18 adapted to the waist-shaped hole on the side of the battery box, and a limiting rod 15 connected to the limiting part 18; the limiting part 18 can pass through the waist-shaped hole and rotate a certain angle under the action of external force so that the limiting part 18 is locked in the waist-shaped hole, and the limiting rod 15 is locked on the limiting groove 8.

[0031] This battery lifting device adopts an integral frame lifting structure. Through the installation of hook 4 and limiting pin 5, compared with existing technologies, the lifting load is transferred from the original pin-driven force distribution to the entire frame. The bottom of the battery box is supported by the support surface 7, while the limiting pin 5 only serves a limiting function to ensure that the hook 4 can always hold the battery box tightly, ensuring lifting stability and improving lifting safety. At the same time, the hook 4 uses a flip-type release mechanism, meeting the battery installation operation space requirements, providing convenience, and improving overall battery installation efficiency.

[0032] In this embodiment, the lifting frame is generally I-shaped, including a lifting beam 1 and lifting plate 2 assemblies connected to both ends of the lifting beam 1. The lifting plate 2 assembly includes two lifting plates 2 spaced apart on the lifting beam 1, with a connecting rod 3 between the outer ends of the two lifting plates 2. One end of a hook 4 is rotatably connected to the connecting rod 3, and the hook 4 can move along the axis of the connecting rod 3. In this embodiment, the connecting rod 3 is a high-strength screw, which passes directly through the two lifting plates 2 and is locked with a nut. The hook 4 can move along the axis of the connecting rod 3, providing ample movement space on the screw to accommodate battery boxes of different sizes, thus achieving versatility. Reinforcing plates 21 are also connected between the two lifting plates 2 and placed on both sides of the lifting beam 1 to ensure that the lifting plates 2 are securely connected to the lifting beam 1. The lifting component includes a lifting lug 11 located in the middle of the lifting beam 1 and a lifting chain 12 connected to the lifting lug 11.

[0033] In this embodiment, a limiting sleeve 13 detachably mounted on the connecting rod 3 is also included. This sleeve is used to limit the position of the hook 4, preventing it from shifting and swaying during hoisting. The limiting sleeve 13 can be a single sleeve mounted on the connecting rod 3 on the left or right side of the hook 4, or two sleeves can be mounted on the connecting rod 3 on the left and right sides of the hook 4, respectively; the specific configuration depends on the position of the hook 4.

[0034] In this embodiment, a limiting member 14 is provided on the outside of the hook 4, to the left or right of the limiting pin 5. One end of the limiting member 14 is fixed to the hook 4, and the other end is bent upward to form the limiting groove 8. One end of the limiting rod 15 is provided with a first rotating part 16, a second rotating part 17, and the limiting part 18 sequentially along its radial direction. The first rotating part 16 is rotatably mounted on the hook 4. The diameter of the first rotating part 16 is not less than the length of the limiting part 18, so that the limiting part 18 can pass through a rotating hole on the hook 4 that matches the first rotating part 16, thereby allowing the first rotating part 16 to be rotatably mounted in the rotating hole. The length of the second rotating part 17 is not less than the wall thickness of the oblong hole, so that the limiting part 18 can be completely placed inside the cavity of the oblong hole. In use, the limiting part 18 can pass through the oblong hole of the battery box, with the second rotating part 17 positioned within the range of the oblong hole wall. By rotating the limiting rod 15, the limiting part 18 is engaged in the oblong hole, and the limiting rod 15 is simultaneously engaged in the limiting groove 8. The limiting pin 5 only serves to limit movement, preventing the hook 4 from flipping outward and falling off. Furthermore, a full circle of guide surface 22 is provided on the outer end face of the limiting part 18 to facilitate smooth entry of the limiting part 18 into the oblong hole when the hook 4 is flipped to lift the battery.

[0035] Of course, it should be noted above that, such as Figure 5 As shown, the battery box typically includes a bottom support 19 and a housing 20 connected to the support 19. The support 19 has an oblong hole on its side wall, and the housing 20 has a clearance groove to avoid the oblong hole. Specifically, the support 19 is typically constructed using a through-type profile, thus the interior of the oblong hole provides space for the limiting part 18 to move.

[0036] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
