[0002] In the new energy industry, particularly during the production and maintenance of energy storage battery packs, large and heavy battery packs need to be handled and positioned. Traditional handling tools often lack clamping mechanisms specifically designed for battery packs, resulting in safety risks such as slipping, shaking, and even falling battery packs. Furthermore, handling is complex and inefficient. Therefore, a dedicated lifting device is needed that can safely, stably, and conveniently handle battery packs while protecting the battery surface from damage.

[0003] A Chinese patent discloses a battery hoist (publication number: CN 217102680 U) comprising: two parallel load-bearing guide rail beams, each of which is provided with a slide rail groove extending along its length on one side close to the other; two parallel cable guide rail beams, each of which is perpendicular to the load-bearing guide rail beam, with both ends of the cable guide beam capable of sliding in the slide rail grooves; a lifting cable, the length of which is adjustable, with two lifting cables provided on one cable guide beam, capable of sliding along the length of the cable guide beam. However, this battery hoist lacks a clamping mechanism specifically designed for battery packs, resulting in safety risks during transportation, such as sliding, shaking, or even falling off of the battery pack, and the operation is complicated and inefficient. Therefore, a special hoist for energy storage battery packs is needed. Utility Model Content

A special hoist for energy storage battery packs is proposed.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: the utility model is a special lifting device for energy storage battery packs, including a main support beam, characterized in that: a lifting point is provided at the center of the top of the main support beam, a clamping block is provided below the lifting point, the clamping block is a cylindrical structure, a lifting chain is connected to one end of the top of the lifting point, a spherical joint is connected to one end of the lifting chain, a hook is connected to one end of the spherical joint, and the hook is associated with the lifting point.

The pad is provided at the connection between the bottom of the sling frame and the battery surface to protect the battery surface from damage. Connecting parts are provided at both ends of the interior of the sling frame, and hooks are installed at both ends of the connecting parts. One end of the bottom of the hook is covered with a non-slip rubber layer. The non-slip rubber layer is covered on the surface of the hook to clamp the battery pack to prevent sliding.

[0007] Preferably, an auxiliary handle is provided at the top center of the sling frame, and the number of the auxiliary handles is 2 and they are set correspondingly, so that the operator can manually control the sling frame to facilitate the precise placement and adjustment of the battery pack.

The two sides of the auxiliary clamping mechanisms are connected to the transverse connecting rod 7. Reinforced clamping mechanisms are provided on both sides of the center of the main support beam 3. Batteries are connected to the bottoms of the auxiliary clamping mechanisms and the reinforced clamping mechanisms.

[0022] In this embodiment, the auxiliary clamping mechanism includes a sling frame 13, which is a convex-shaped structure as a whole and is hollow inside. A pad 15 is provided at the connection between the bottom of the sling frame 13 and the battery surface. The pad 15 is provided at the connection between the bottom of the sling frame 13 and the battery surface to protect the battery surface from damage. Connecting parts 14 are provided at both ends of the sling frame 13. The connecting parts 14 are fixed to the sling frame 13 by screwing. Hooks 16 are installed at both ends of the connecting part 14. One end of the bottom of the hook 16 is covered with an anti-slip rubber layer 17. The anti-slip rubber layer 17 is covered on the surface of the hook 16 to clamp the battery pack 9 to prevent sliding.

[0023] In this embodiment, an auxiliary handle 1 is provided at the top center of the sling frame 13, and the auxiliary handle 1 is fixed to the top of the sling frame 13 by screwing. There are two auxiliary handles 1 and they are set accordingly, which are used for the operator to manually control the sling frame 13, so as to facilitate the precise placement and adjustment of the battery pack 9.

[0024] In this embodiment, slot-shaped holes are provided around the top of the battery, and the slot-shaped holes cooperate with the hooks 16. The hooks 16 are inserted into the slot-shaped holes to achieve a fixed connection between the battery pack 9 and the sling.

[0025] In this embodiment, the enhanced clamping mechanism includes a vacuum suction cup 8, and a connecting column 2 is provided at the top of the vacuum suction cup 8. The connecting column 2 is associated with the main support beam 3. There are two vacuum suction cups 8 and they are arranged accordingly. As part of the enhanced clamping mechanism, the vacuum suction cup 8 is used to enhance the fixation of the battery pack 9 through vacuum adsorption.

[0026] In this embodiment, there are two transverse connecting rods 7 and they are arranged corresponding to the center of the main support beam 3.

[0027] The implementation principle of this embodiment is as follows: first, the auxiliary clamping mechanism cooperates with the slotted hole on the top of the battery pack 9 through the hook 16 to achieve preliminary fixation. At the same time, the strengthening clamping mechanism forms a negative pressure on the battery surface through the vacuum suction cup 8 to provide additional adsorption force to ensure the stability of the battery pack 9 during transportation. Then, it is connected to the hook of the lifting equipment through the lifting chain 10 and the spherical joint 11. The design of the spherical joint 11 allows the sling to swing freely within a certain range to adapt to the lifting requirements of different angles and positions. The sling lifts the battery, and the hook 16 automatically hooks the slotted hole to lift the battery. During this period, the auxiliary handle 1 can be manually held to maintain balance, and then the batteries can be placed in the designated positions in turn for stacking.
