Description

Technical Field

[0001] The utility model relates to the technical field of hoisting structures, and more specifically, to a hoisting device for a battery module. Background Art

[0002] Compared with other lead-acid batteries, industrial batteries are heavier, ranging from 10kg to 160kg. It can be seen that it is difficult to carry industrial batteries by manpower, so industrial battery lifting devices are needed. Battery modules of different sizes and specifications need to be matched with lifting tools of corresponding sizes during lifting, otherwise the lifting process of the battery module cannot be completed, and replacing the lifting tools of corresponding sizes will seriously affect the assembly efficiency of the production line. On the other hand, when frequently changing tools, due to the efficiency requirements of the production line, there are certain restrictions on the replacement time, which requires the replacement personnel to replace quickly, which poses certain safety risks and uncontrollable.

[0003] At present, existing technicians have proposed a lifting tool that can adapt to battery modules of different lengths and widths and is easy to disassemble and assemble. For example, the Chinese patent with publication number CN 216889707 U discloses a module lifting device, including a main beam; a lifting lug is provided in the middle position of the main beam, and at least one set of sliding blocks is provided on each side of the lifting lug along the length direction of the main beam; the sliding block is connected to the main beam in a manner that can be adjusted along the length direction of the main beam, and a side rod is connected to the sliding block; the middle position of the side rod is detachably connected to the sliding block, and hooks are installed at both ends of the side rod; the sliding block is used to lift battery modules of different widths by installing side rods of different lengths.

[0004] However, the device still has some problems. There is only one lifting ear and it is located in the middle of the beam, while the sliders on both sides can slide to any position without limitation, which may easily lead to unbalanced force on the lifted battery and cause instability of the lifted battery during movement. In addition, a first lifting ring, a second lifting ring, a connecting rod and multiple second connecting members are provided for the connection structure between the upper slider and the lower hook, and shaking may occur between the multiple structures. In addition, the side panels and the cross panels of the slider are in contact with the beam and can be tightened, and there is no room for movement when tightened. Utility Model Content
