Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a lifting equipment for a power battery module. Background Technology

[0002] The existing power battery module lifting tool uses chain-connected iron hooks to hook the battery module lifting holes to complete the lifting. However, the lifting tool cannot be adjusted and can only be adapted to a single size module, which cannot be adapted to multiple models. Changing the model is not easy and will affect the production cycle. Moreover, the iron hook is bent by human, which cannot be completely matched to the lifting hole, resulting in the risk of falling and injuring people during the lifting process. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a power battery module lifting tool that is compatible with the lifting of various battery module models. It is easy and labor-saving to operate, safe and reliable, and has no risk of falling off.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A power battery module lifting device includes a lifting frame, which is a rectangular frame structure composed of two parallel horizontal beams and two parallel vertical beams. A balance bar is provided below the vertical beams, and both ends of the balance bar are mounted on the horizontal beams via bracket assemblies. The bracket assemblies are movably mounted on the horizontal beams. Mounting blocks are provided at both ends of the balance bar, and a hook connecting rod is provided below the balance bar. Both ends of the hook connecting rod are connected to lifting rings on the mounting blocks via lifting ropes. A set of hooks for lifting battery modules is installed on the hook connecting rod.

[0006] Preferably, the crossbeam, longitudinal beam, and balance bar are all made of square aluminum profiles. The aluminum profiles include a central column and four side columns. The central column and the side columns are all hollow bodies. The side columns are connected to the central column by connecting ribs, and a T-shaped groove is formed between any two adjacent side columns.

[0007] Preferably, a connecting plate is provided in the middle of the hanger, and a connecting flange is provided on the connecting plate.

[0008] Preferably, the hanger is provided with handles at both ends, and the handles are mounted on the longitudinal beam.

[0009] Preferably, the support assembly includes a slider and a mounting member, the slider is mounted on the mounting member, the slider is slidably mounted on the crossbeam, and the mounting member is fixed to the balance bar.

[0010] Compared with the prior art, the advantages of this utility model are as follows: In view of the defects of the existing module lifting tool, the flange is connected to the KBK rigid lifting arm. The tapered roller bearing inside the flange and the lifting bracket enable the entire lifting tool to rotate 360 ​​degrees, which facilitates module assembly and boxing. The lifting bracket is made of lightweight aluminum profile to meet the strength requirements while reducing weight. The support assembly is movable on the lifting bracket to adapt to modules of different lengths and ensure that the hook is perpendicular to the module. The hook has a contoured structure to adapt to the module lifting hole and has a foolproof protrusion to prevent it from falling off. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-2 A power battery module lifting device includes a lifting frame 3, with a connecting plate 2 in the middle of the lifting frame 3. A connecting flange 1 is provided on the connecting plate 2, which is connected to a KBK rigid lifting arm. A tapered roller bearing inside the flange 1, in conjunction with the lifting frame, allows the entire lifting device to rotate 360 ​​degrees. The lifting frame 3 has a rectangular frame structure, consisting of two parallel horizontal beams 31 and two parallel vertical beams 32. A balance bar 11 is provided below the vertical beams 32. The horizontal beams 31, vertical beams 32, and balance bar 11 are all made of square aluminum profiles. Each aluminum profile includes a central column 13 and four side columns 14. The central column 13 and side columns 14 are hollow bodies. The side columns 14 are connected to the central column 13 via connecting ribs, and any two adjacent side columns 14 form a T-slot 15. Handles 8 are provided at both ends of the lifting frame 3, and the handles 8 are mounted on the vertical beams 32.

[0016] The balance bar 11 is mounted on the crossbeam 31 at both ends via bracket assemblies 4. The bracket assembly 4 is movably mounted on the crossbeam 31 and includes a sliding member 41 and a mounting member 42. The sliding member 41 is mounted on the mounting member 42 and is slidably mounted on the crossbeam 32. The mounting member 42 is fixed to the balance bar 11. Mounting blocks 5 are provided at both ends of the balance bar 11, and a hook connecting rod 10 is provided below the balance bar 11. The hook connecting rod 10 is connected at both ends to lifting rings 6 on the mounting blocks 5 via lifting ropes 9. A set of hooks 7 for lifting the battery module 12 is mounted on the hook connecting rod 10. The bracket assembly 4 is movable on the hanger 3 to adapt to modules of different lengths, ensuring that the hooks 7 are perpendicular to the modules. The hooks 7 have a contoured structure to adapt to the module's lifting holes and have anti-fouling protrusions to prevent them from falling off.

[0017] For first-time use, place the battery module 12 under the hanger 3, adjust the bracket assembly 4 so that the width of the lifting device is consistent with the width of the module, and adjust the position of the hooks 7 according to the width of the lifting hole of the battery module 12 so that the hooks 7 on both sides can be hooked into the lifting hole of the battery module for lifting. It is connected to the KBK rigid boom through the flange 1. The tapered roller bearing inside the flange 1 cooperates with the hanger to allow the entire lifting device to rotate 360 ​​degrees, which facilitates module assembly and placement into the box. After the lifting is completed, place the battery module 12 in a stress-free state and remove the hooks 7 on both sides.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
