[0020] Such as Figure 1 、 Figure 2The lightweight lifting device shown includes a main bracket 1, and the main bracket 1 is made of profiled aluminum. Hoisting groups are symmetrically arranged at both ends of the main bracket 1. Each hoisting group includes a fixing block 4, and the fixing block 4 is clamped at the end of the main bracket 1. A connecting shaft 5 is connected to the fixing block 4, and connecting pieces 6 are arranged at both ends of the connecting shaft 5. The lower parts of the connecting pieces 6 are connected to both ends of a connecting rod 7. Two sets of distributed link structures are symmetrically arranged at both ends of the connecting rod 7, and the two distributed link structures are interconnected by an upper grip rod 13 and a lower grip rod 9. An upper clamping block 12 and a lower clamping block 11 are arranged on each distributed link structure. By grasping the upper grip rod 13 and the lower grip rod 9, the distance between the upper clamping block 12 and the lower clamping block 11 is controlled by the distributed link structure to clamp the edge of the battery pack.

[0021] The distributed link structure, as Figure 3 shown, includes two symmetrically arranged clamping plates 8. A first connecting rod 14, a second connecting rod 15, a third connecting rod 16, and a fourth connecting rod 17 are clamped between the two clamping plates 8. One end of the first connecting rod 14 is connected to the end of the upper grip rod 13 through a bolt passing through the clamping plate 8. A long strip-shaped limiting groove is arranged at the place where the bolt passes through the clamping plate 8. The other end of the first connecting rod 14 is connected to the center of the second connecting rod 15. One end of the second connecting rod 15 is connected to the clamping plate 8, and the other end is connected to one end of the fourth connecting rod 17. One end of the third connecting rod 16 is connected to the clamping plate 8, and the other end is connected to the upper clamping block 12. The other end of the fourth connecting rod 17 is connected to the upper clamping block 12. A spring 10 is arranged on one side of the clamping plate 8. One end of the spring 10 is connected to the end of the upper grip rod 13, and the other end is fixed on the clamping plate 8. The lower clamping block 11 is connected to the bottom of the clamping plate 8 corresponding to the position of the upper clamping block 12. By grasping the upper grip rod 13 and the lower grip rod 9, the first connecting rod 14 rotates the second connecting rod 15, driving the upper clamping block 12 to rotate around the point where the third connecting rod 16 is connected to the clamping plate 8, so that the upper clamping block 12 and the lower clamping block 11 are separated to accommodate the edge of the battery pack. After releasing the upper grip rod 13 and the lower grip rod 9, under the action of the spring 10, the upper clamping block 12 resets, causing the upper clamping block 12 and the lower clamping block 11 to clamp the edge of the battery pack.

[0022] The connecting piece 6 is a chain, and the chain has higher flexibility, enabling the hoisting group to adapt to the use of battery packs of different sizes without moving the fixing block 4.

[0023] The fixing block 4 is connected to the main bracket 1 through bolts. Multiple connecting holes are arranged on the main bracket 1. The fixing block 4 is connected to different connecting holes as needed to adjust the distance between the fixing blocks 4 at both ends of the main bracket 1, further expanding the range of applicable battery packs.

[0024] A hoisting plate 2 is arranged on the main bracket 1. The hoisting plate 2 is a trapezoidal plate body, and the hoisting plate 2 is connected to the main bracket 1 through bolts. The hoisting plates 2 are symmetrically arranged on both sides of the main bracket 1, and hoisting rods are connected to the tops of the two hoisting plates 2 for hooking by mobile devices such as gantry cranes.

[0025] On both sides of the main bracket 1, there are handles, which facilitate the personnel to pick up and adjust the lifting tool. The handles can be connected to the main bracket 1 or to the lifting plate 2.

[0026] At the bottom of the upper clamping block 12, there is an upper positioning screw 19, and at the top of the lower clamping block 11, there is a lower positioning screw 20. After clamping the edge of the battery pack, the upper positioning screw 19 and the lower positioning screw 20 are embedded into the corresponding grooves on the edge of the battery pack to prevent the battery pack from slipping off during the movement.

[0027] On the lifting group on one side of the main bracket 1, there is a storage rack 18 connected. The storage rack 18 is connected to the connecting rod 7. The storage rack 18 can be used to place devices such as remote controls. There are limit blocks on the storage rack 18 to prevent the placed devices from falling.

[0028] The overall structure of the utility model is simple and lightweight, which is convenient for the operator to clamp and carry the battery pack, can ensure the stability of the battery pack during movement, and is convenient and fast to use.
