[0041] As described in the background art, for the same lithium battery cell, the assembled lithium battery square module is externally provided with an end plate, and a lifting hole is arranged on the end plate. When hoisting and transporting, the hoisting tool hooks the lifting hole. However, the positions of the lifting holes of different lithium battery square modules are different, and the same hoisting tool cannot simultaneously meet the handling and hoisting of multiple different lithium battery square modules. When hoisting and transporting different lithium battery square modules, it is necessary to repeatedly switch the hoisting tooling 100, resulting in inconvenient production work. Moreover, producing multiple different hoisting toolings 100 will also cause waste of material costs.

[0042] In view of this, the embodiment of the present utility model provides a hoisting tooling 100 and a hoisting device. The hoisting tooling 100 rotates two hoisting mechanisms 130. According to the different positions of the hook blocks 1331 on both sides of its hook plate 133, it hoists and transports multiple different lithium battery square modules.

[0043] The following is an exemplary description of the hoisting tooling 100 provided by the embodiment of the present utility model:

[0044] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a hoisting tooling 100 provided by an embodiment of the present utility model. The hoisting tooling 100 includes a cross bar 110, two lifting rings 120, and two hoisting mechanisms 130. The two hoisting mechanisms 130 are respectively arranged at both ends of the cross bar 110 and are limited by the two lifting rings 120. The hoisting mechanism 130 includes a lifting ring 131, a rotating assembly 132, and a hook plate 133. One end of the lifting ring 131 is provided with a first installation hole 1311, and the lifting ring 131 is installed on the cross bar 110 through the first installation hole 1311. The other end of the lifting ring 131 is connected to the rotating assembly 132, and the hook plate 133 is connected to the rotating assembly 132. The hook plate 133 can rotate with the rotating assembly 132. Two hook blocks 1331 with different spacings are respectively arranged on both sides of the hook plate 133, and the hook blocks 1331 are used to hook the end plate lifting hole 201 of the battery pack module 200.

[0045] Two lifting rings 120 are provided at both ends of the crossbar 110. One end of the lifting ring 131 of the lifting mechanism 130 is provided with a first mounting hole 1311. The first mounting hole 1311 is as Figure 4 shown. Through the first mounting hole 1311, the entire lifting mechanism 130 is hung on the crossbar 110. The two lifting rings 120 also play a role in limiting the lifting mechanism 130. The lifting ring 131 is connected to the hook plate 133 through a rotating assembly 132. The hook plate 133 can rotate with the rotating assembly 132 to enable the hook plate 133 to turn its face. Two hook blocks 1331 with different spacings are respectively arranged on both sides of the hook plate 133. According to the different hook blocks 1331 on the two hook plates 133 and by rotating the hook plate 133, multiple hook combinations can be combined, and then multiple different lithium battery square modules can be lifted and transported.

[0046] Please refer to Figure 1 、 Figure 2 、 Figure 3 . When the battery pack module 200 needs to be lifted and transported, when the battery pack module 200 is as Figure 2 shown, the end plate lifting holes 201 at both ends of the battery pack module 200 are on the inner side. Rotate and adjust the hook plates 133 of the two lifting mechanisms 130 to make the hook blocks 1331 on the inner side. Align the positions of the hook blocks 1331 at both ends of the lifting tooling 100 with the positions of the end plate lifting holes 201 and hook the end plate lifting holes 201 for lifting and transporting. Similarly, when the battery pack module 200 is as Figure 3 shown, the end plate lifting holes 201 at both ends of the battery pack module 200 are on the outer side. Rotate the two hook plates 133 by 180 degrees to lift and transport the battery pack module 200. It can be understood that when the end plate lifting hole 201 at one end of the battery pack module 200 is on the inner side and the end plate lifting hole 201 at the other end is on the outer side, it can also be adjusted according to the actual situation.

[0047] By using this lifting tooling 100 and rotating the two lifting mechanisms 130, according to the different positions of the hook blocks 1331 on both sides of the hook plate 133, multiple different battery pack modules 200 can be lifted and transported, thus eliminating the need to repeatedly replace the lifting tooling 100, making the production work more convenient. Moreover, the multiple uses of one lifting tooling 100 can also save the production cost of the lifting tooling 100.

[0048] In a possible implementation manner, for the convenience and stability of the rotation of the rotating assembly 132, refer to Figure 4 、 5, 6. One end of the lifting ring 131 is provided with a T-shaped opening 1312. The rotating assembly 132 includes a connecting head 1321 and a connecting hanging part 1322. The connecting head 1321 is a stepped joint. One end is a first cylinder 13211, and the other end is a second cylinder 13212. The bottom area of the first cylinder 13211 is larger than the bottom area of the second cylinder 13212. The first cylinder 13211 is placed in the wide opening of the T-shaped opening 1312, and the second cylinder 13212 is placed in the narrow opening of the T-shaped opening 1312. The connecting head 1321 is limited in the T-shaped opening 1312 by a clamping block 1323. The connecting hanging part 1322 is connected to the hook plate 133.

[0049] It can be seen from Figure 4 that one end of the lifting ring 131 is provided with a first mounting hole 1311 and a T-shaped opening 1312 at one end. Among them, the upper part is the wide opening and the lower part is the narrow opening. It can be seen from Figure 5 that the connecting head 1321 of the rotating assembly 132 is a stepped joint. The upper part is a first cylinder 13211 and the lower part is a second cylinder 13212. The bottom area of the first cylinder 13211 is larger than the bottom area of the second cylinder 13212. The first cylinder 13211 is placed in the wide opening of the T-shaped opening 1312, and the second cylinder 13212 is placed in the narrow opening of the T-shaped opening 1312. By such setting, the narrow opening of the T-shaped opening 1312 catches the first cylinder 13211 so that it will not fall off. It can be seen from Figure 6 that the connecting head 1321 is clamped in the T-shaped opening 1312 by the clamping block 1323. Since the connecting head 1321 is composed of two cylinders, one end of the lifting ring 131 is provided with a T-shaped opening 1312 and the clamping action of the clamping block 1323, it can rotate in the T-shaped opening 1312, which can make the rotating assembly 132 rotate conveniently and can be firmly fixed in the T-shaped opening 1312.

[0050] Optionally, the two hook blocks 1331 on one side of the hook plate 133 are arranged between the two hook blocks 1331 on the other side of the hook plate 133.

[0051] Please refer to Figure 7 , the setting of the hook block 1331 can meet the battery pack modules 200 with different positions of the three end plate lifting holes 201. As described above, the end plate lifting holes 201 at both ends of the battery pack module 200 are on the inner side, the end plate lifting holes 201 at both ends of the battery pack module 200 are on the outer side, the end plate lifting hole 201 at one end of the battery pack module 200 is on the inner side, and the end plate lifting hole 201 at the other end is on the outer side.

[0052] Optionally, please refer to Figure 8, the hook plate 133 is provided with a plurality of hook mounting holes 1332. In addition to the above three cases, there may be other cases for the end plate lifting holes 201 of the battery pack module 200. For example, for the two end plate lifting holes 201 at one end, one is on the outside and the other is on the inside. We can adjust the position of the hook block 1331 according to the actual situation and install the hook block 1331 in different hook mounting holes 1332 to adapt to the more complex design of the end plate lifting holes 201 of the battery pack module 200.

[0053] In a possible implementation, since the sizes of the battery pack modules 200 may also be different, in order to adapt to battery pack modules 200 of different sizes, refer to Figure 9 , the two lifting rings 120 are respectively a wide-spacing lifting ring 121 and a narrow-spacing lifting ring 122; the lifting mechanism 130 at the same end as the wide-spacing lifting ring 121 is slidable.

[0054] From Figure 9 it can be seen that for battery pack modules 200 of different sizes, by adjusting the position of the lifting mechanism 130 at the same end as the wide-spacing lifting ring 121, it can adapt to battery pack modules 200 of different sizes.

[0055] Please refer to Figure 10 , where the wide-spacing lifting ring 121 includes a first lifting hole 1211 and a wide-spacing mounting groove 1212; two second mounting holes 1213 are opened on the opposite two groove side walls of the wide-spacing mounting groove 1212; the lifting ring 131 of a lifting mechanism 130 is arranged in the wide-spacing mounting groove 1212.

[0056] The first lifting hole 1211 is used to connect with a hoist. The cross bar 110 passes through the two second mounting holes 1213 to install the wide-spacing lifting ring 121 on the cross bar 110. The lifting ring 131 of a lifting mechanism 130 is arranged in the wide-spacing mounting groove 1212 and can slide in the wide-spacing mounting groove 1212. When it slides to a suitable position, the lifting mechanism 130 can be fixed with a C-shaped snap ring.

[0057] Similarly, the narrow-spacing lifting ring 122 includes a second lifting hole and a narrow-spacing mounting groove; two second mounting holes 1213 are opened on the opposite two groove side walls of the narrow-spacing mounting groove; the lifting ring 131 of a lifting mechanism 130 is arranged in the narrow-spacing mounting groove.

[0058] Furthermore, please continue to refer to Figure 10 , a gap 1214 is opened on the groove side wall, and the gap 1214 can be locked with a bolt.

[0059] The diameter of the second mounting hole 1213 is slightly larger than the diameter of the crossbar 110, facilitating the passing through of the crossbar 110. However, there will be some looseness. A slit 1214 is provided on the side wall of the groove, and the slit 1214 is locked by a bolt to clamp the crossbar 110.

[0060] Optionally, the crossbar 110 is a linear optical axis. The linear optical axis has high-quality materials and precise manufacturing processes, which can enable the crossbar 110 to have a long service life.

[0061] Based on the above implementation manners, an embodiment of the present application further provides a hoisting device, including the above-mentioned hoisting tooling 100 and a crane.

[0062] After the battery pack module 200 is hoisted by the hoisting tooling 100, the crane is connected to the lifting ring 120 to transport the battery pack module 200 to the next working station.

[0063] In summary, an embodiment of the present invention provides a hoisting tooling and a hoisting device. The hoisting tooling includes a crossbar, two lifting rings, and two hoisting mechanisms. The two hoisting mechanisms are respectively arranged at both ends of the crossbar. The hoisting mechanism includes a lifting ring, a rotating assembly, and a hook plate. A first mounting hole is provided at one end of the lifting ring, and the lifting ring is mounted on the crossbar through the first mounting hole. The other end of the lifting ring is connected to the rotating assembly, and the hook plate is connected to the rotating assembly. The hook plate can rotate with the rotating assembly. Two hook blocks with different spacings are respectively arranged on both sides of the hook plate. The hook blocks are used to hook the end plate lifting holes of the battery pack module. The two lifting rings are a wide-spacing lifting ring and a narrow-spacing lifting ring respectively, and the hoisting mechanism at the same end of the wide-spacing lifting ring can slide. Through the rotation of the two hoisting mechanisms, according to the hook blocks on both sides of the hook plate, various different lithium battery square modules can be hoisted and transported. By adjusting the position of the wide-spacing lifting ring, one of the hoisting mechanisms can be moved to adapt to lithium battery square modules of different sizes.
