[0031] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0032] In manufacturing plants, products need to be stacked, which typically requires hoisting for transportation or transfer. Because battery packs are usually large and heavy, and may contain hazardous substances or special battery materials, special attention must be paid to safety, equipment selection, and operating procedures during hoisting. Battery pack hoisting refers to the operation of moving, stacking, or loading / unloading battery packs using hoisting equipment during battery production, assembly, repair, or transportation. However, most existing battery pack lifting tools are not suitable for scenarios where the gap between the battery pack bottom shell and the work surface is small.

[0033] Based on this, please refer to Figure 1 , Figure 2 and Figure 3 The lifting device 1000 provided in the embodiments of this utility model can effectively improve the aforementioned technical problems. The lifting device 1000 is suitable for scenarios where the gap between the part to be lifted and the work platform is small. The lifting device 1000 in this embodiment is mainly used for lifting battery packs. Of course, the lifting device 1000 can also be used for other scenarios where the gap between the part to be lifted and the work platform is small, and is not limited to lifting other parts besides battery packs.

[0034] Figure 1 This is a schematic diagram from a first-view perspective of the lifting device 1000 provided in an embodiment of this utility model; Figure 2 This is a schematic diagram of the first state of the lifting device 1000 provided in an embodiment of the present invention from a second perspective;

[0035] Figure 3 This is a schematic diagram of the second state of the lifting device 1000 provided in an embodiment of this utility model from a second perspective. Figure 1 , Figure 2 and Figure 3 As shown, the lifting device 1000 in this embodiment includes a bracket 100, a pin 200, a first hook 300, and a second hook 400. The bracket 100 is used to connect with an external lifting structure. The pin 200 passes through the bracket 100, and the bracket 100 can rotate relative to the pin 200. The first hook 300 and the second hook 400 are both connected to the pin 200. The first hook 300 has a first strip hole 311, and the second hook 400 has a second strip hole 411. The extension direction of the first strip hole 311 and the extension direction of the second strip hole 411 are both perpendicular to the axial direction of the pin 200. The pin 200 is located inside the first strip hole 311 and the second strip hole 411. When hoisting is required, first rotate the bracket 100 so that the first hook 300 and the second hook 400 move relative to the pin 200. Then, move the first hook 300 relative to the pin 200 along the extension direction of the first slot 311, or pull the second hook 400 to move it relative to the pin 200 along the extension direction of the second slot 411, so that the first hook 300 and the second hook 400 are misaligned. The misalignment of the first hook 300 and the second hook 400 facilitates insertion of the hooks into the lifting holes. Then, insert either the first hook 300 or the second hook 400 into the lifting hole of the component to be hoisted. After one hook is fully inserted, pull the other hook so that their lower parts are at the same horizontal level, thus achieving the engagement of the hooks with the lifting holes. Finally, rotate the bracket 100 until it is parallel to the hooks to complete the hoisting. The aforementioned lifting device 1000 enables lifting to be completed in scenarios where the gap between the part to be lifted and the work platform is small, and the lifting device 1000 will not occupy too much space under the lifting hole of the part to be lifted.

[0036] To facilitate adjustment of the distance between the first hook 300 and the second hook 400 according to the size of the lifting hole, please refer to [link / reference needed]. Figures 1-3 In this embodiment, the lifting device 1000 further includes a spacing adjustment component 500, which is disposed between the first hook 300 and the second hook 400. The spacing adjustment component 500 is used to adjust the spacing between the first hook 300 and the second hook 400. Specifically, the spacing adjustment component 500 includes a first spacer portion 510 and a second spacer portion 520 connected in sequence. The first spacer portion 510 is sleeved on the pin 200 and can rotate around the axis of the pin 200. The thickness of the first spacer portion 510 is less than the thickness of the second spacer portion 520. By rotating the spacing adjustment component 500, the first hook 300 and the second hook 400 may be engaged with either the first spacer portion 510 or the second spacer portion 520 to adjust the spacing between them. By replacing the spacing adjustment component 500 and changing the thickness of the first spacer portion 510 and the second spacer portion 520, the requirements for lifting holes of different diameters can be met, improving versatility. To ensure that the hooks will not fall off after the first hook 300 and the second hook 400 are simultaneously engaged in the lifting hole, the maximum dimension between the first hook 300 and the second hook 400 must be greater than the diameter of the lifting hole.

[0037] Furthermore, the spacing adjustment component 500 can also be designed to include a first connecting plate, a second connecting plate, and a locking component. One end of the first connecting plate is connected to the first hook 300, and the other end of the first connecting plate is movably connected to one end of the second connecting plate via the locking component. The other end of the second connecting plate is connected to the second hook 400. Specifically, the first connecting plate has a first adjustment hole, and / or the second connecting plate has a second adjustment hole, with the locking component passing through the first adjustment hole and / or the second adjustment hole. By changing the position of the locking component relative to the first strip hole 311 and / or the second strip hole 411, the spacing between the first hook 300 and the second hook 400 can be changed. Of course, the spacing adjustment component 500 can also be designed in other structural forms, which are not limited here.

[0038] Please see Figures 1-3In this embodiment, the lifting device 1000 further includes a first spring 600, which is sleeved on the pin 200. One end of the first spring 600 abuts against the first hook 300, and the other end abuts against the bracket 100. The lifting device 1000 also includes a second spring 700, which is sleeved on the pin 200. One end of the second spring 700 abuts against the second hook 400, and the other end abuts against the bracket 100. By providing the first spring 600, a preload force can be applied to the first hook 300 to move towards the second hook 400. By providing the second spring 700, a preload force can be applied to the second hook 400 to move towards the first hook 300, so that the first hook 300 and the second hook 400 move closer to each other, thereby further ensuring the stability of their lifting and further preventing the hooks from falling off.

[0039] To facilitate the pulling of the first hook 300 and / or the second hook 400 and to facilitate operation by the operator, the lifting device 1000 in this embodiment further includes a pull ring 800. The pull ring 800 is disposed on the first hook 300 and is used to pull the first hook 300 to move relative to the pin 200 along the extension direction of the first strip hole 311; and / or, the pull ring 800 is disposed on the second hook 400 and is used to pull the second hook 400 to move relative to the pin 200 along the extension direction of the second strip hole 411.

[0040] Please continue reading. Figures 1-3 In this embodiment, the first hook 300 includes a first connecting portion 310 and a first lifting portion 320. The first connecting portion 310 and the first lifting portion 320 are connected at an angle. The first connecting portion 310 has a first strip-shaped hole 311, and the first lifting portion 320 is used to mate with the lifting hole of the part to be lifted. The second hook 400 includes a second connecting portion 410 and a second lifting portion 420. The second connecting portion 410 and the second lifting portion 420 are connected at an angle. The second connecting portion 410 has a second strip-shaped hole 411, and the second lifting portion 420 is used to mate with the lifting hole of the part to be lifted. The shape and structure of the first hook 300 may be the same as or different from that of the second hook 400, and this is not limited here. In this embodiment, the shape and structure of the first hook 300 are the same as those of the second hook 400. Both the first lifting section 320 and the second lifting section 420 are plate-shaped structures. The first lifting section 320 can be connected to the first connecting section 310 at a right angle or an acute angle; the second lifting section 420 can be connected to the second connecting section 310 at a right angle or an acute angle. Of course, the first lifting section 320 and the second lifting section 420 can also be designed in other shapes, which are not limited here.

[0041] To further reduce the space occupied by the lifting parts, in this embodiment, the connecting plane between the first lifting part 320 and the first connecting part 310 is parallel to the axial direction of the pin 200, and / or, the connecting plane between the second lifting part 420 and the second connecting part 410 is parallel to the axial direction of the pin 200. Of course, the first lifting part 320 and the second lifting part 420 can also be designed as other shapes such as "L" shape or triangle shape, which are not limited here.

[0042] The working principle of the lifting device 1000 provided in this embodiment is as follows:

[0043] When hoisting is required, first rotate the bracket 100 so that the first hook 300 and the second hook 400 move relative to the pin 200. Then, move the first hook 300 relative to the pin 200 along the extension direction of the first slot 311, or pull the second hook 400 so that it moves relative to the pin 200 along the extension direction of the second slot 411, thus misaligning the first hook 300 and the second hook 400 so that one hook can be inserted into the hoisting hole of the part to be hoisted. Then, insert either the first hook 300 or the second hook 400 into the hoisting hole of the part to be hoisted. After one hook is fully inserted into the hoisting hole, pull the other hook so that the lower parts of both are at the same horizontal position, thus achieving the locking engagement between the hook and the hoisting hole. Finally, rotate the bracket 100 until it is parallel to the hook to complete the hoisting.

[0044] In summary, the lifting device 1000 includes a bracket 100, a pin 200, a first hook 300, and a second hook 400. The bracket 100 is used to connect with an external lifting structure. The pin 200 passes through the bracket 100, and the bracket 100 can rotate relative to the pin 200. Both the first hook 300 and the second hook 400 are connected to the pin 200. The first hook 300 has a first slot 311, and the second hook 400 has a second slot 411. The extension directions of the first slot 311 and the second slot 411 are both perpendicular to the axial direction of the pin 200. The pin 200 is located within the first slot 311 and the second slot 411. With the lifting device 1000, lifting can be completed even in scenarios where the gap between the part to be lifted and the work surface is small, and the lifting device 1000 will not occupy too much space below the lifting hole of the part to be lifted.
