[0024] The present invention will now be described in further detail with reference to the accompanying drawings:

[0025] Example 1 provides a battery pack lifting device, such as... Figures 1-3 As shown, it includes a main frame 1 and at least one set of lifting devices 2, and a plurality of first lifting rings 12 are provided at intervals on the upper side of the main frame 1;

[0026] The lifting device 2 includes a claw 3, a shackle 4, and a lifting rod 6 or hook that cooperates with the receiving part of the battery pack (not shown in the figure);

[0027] A sliding gripper 3 is installed on at least one first crossbeam 11 of the main frame 1;

[0028] Shackle 4 is installed on the lower side of the gripper 3; boom 6 is installed on shackle 4.

[0029] The position of the lifting rod 6 is adjusted by sliding the claw 3, and the lifting rod 6 is installed on the receiving part of the battery pack, which can accommodate battery packs of different specifications or models. The main frame 1, lifting tool 2, and battery pack are lifted by the first lifting ring 12, which can realize the transfer, movement and maintenance of battery packs. It is convenient to operate and safe and reliable, and the lifting operation can be performed by external forklifts or lifting devices. There are no requirements for the installation position of the battery pack on the lower side.

[0030] The main frame 1 is equipped with at least one first handle 15 on its upper side for easy manual movement. More specifically, two first handles 15 are respectively installed on the first crossbeams 11 on both sides of the main frame 1. The first crossbeams 11 on both sides are parallel.

[0031] The main frame 1 can be square, circular, or elliptical, but is not limited to these.

[0032] Optionally, multiple reinforcing members 7 are provided on the main frame 1 to improve the strength of the main frame 1. Specifically, reinforcing members (7) are provided at multiple connections of the first crossbeam 11.

[0033] Example 2, as Figure 2 The gripper 3 includes an upper mounting block 31 and a lower mounting block 32 detachably mounted on the lower side of the upper mounting block 31, the upper mounting block 31 and the lower mounting block 32 forming a gripping structure.

[0034] A third lifting ring 33 is provided at the lower end of the lower mounting block 32, and the shackle 4 is installed on the third lifting ring 33.

[0035] like Figure 3 The shackle 4 can be a D-type shackle 4 or an arc-shaped shackle 4. Specifically, the shackle 4 includes a U-shaped shackle body 41 and a pin 45. The two ends of the shackle body 41 are respectively provided with a first buttonhole 42 and a second buttonhole 43. One end of the pin 45 passes through the first buttonhole 42 and is detachably installed on the second buttonhole 43 by threads. The other end of the pin 45 is provided with a second handle 46.

[0036] Example 3 also provides an installation structure for the sling 5. The upper side of the sling 5 is mounted on the shackle 4 through a first through hole 51, and the lower side is provided with a second through hole 52. The upper end of the lifting rod 6 is mounted on the second through hole 52 through a second lifting ring 61. The flexible sling 5 provides a more flexible operating method.

[0037] like Figure 2 The lower side of the lifting rod 6 is threaded, and the first bolt 62 is installed on the lower side of the lifting rod 6 via the thread.
