[0038] The energy storage cabinet is the basic unit of the energy storage device. The interior of the energy storage cabinet is used to accommodate battery modules and control modules. Inside the energy storage cabinet, a high-voltage and / or high-energy battery cabinet (also known as an energy storage battery cabinet) is mainly formed by connecting multiple battery packs in series and parallel for use. In the transportation process of related technology energy storage cabinets, the forklift insertion method or the hoisting method is usually adopted. Among them, the hoisting method is the most commonly used. Therefore, hoisting holes are usually installed at the top of the energy storage cabinet. When loading, unloading or transferring the energy storage cabinet on site, a lifting ring can be installed on the top of the energy storage cabinet to assist in the hoisting of the energy storage cabinet. At present, the lifting rings on the top of the energy storage cabinet are usually directly fixed on the top of the cabinet body and are located on the top cover of the cabinet. The strength of the connection position of the lifting ring is weak, and it is easy to deform or fall during the hoisting process, which is prone to danger and there are potential safety hazards.

[0039] In view of this, the present embodiment provides a hoisting structure, aiming to improve the strength of the position of the hoisting member 3 by arranging a hoisting assembly 2 at the connection of the column 10 and the cross beam 11, and ensure the stability and safety during hoisting, so as to solve the above technical problems.

The plurality of hoisting assemblies 2 are respectively arranged at the four corners of the frame body 1. The hoisting assembly 2 includes a connecting member 20 and a hoisting member 3. The connecting member 20 is arranged at the connection of the column 10 and the cross beam 11, and the hoisting member 3 is detachably arranged on the connecting member 20. When hoisting, the hoisting member 3 is simultaneously affected by the column 10 and the cross beam 11, and is mainly affected by an upward pulling force on the hoisting member 3. Therefore, its force direction is parallel to the extending direction of the column 10, which can improve the strength of the position of the hoisting member 3 and ensure the stability of the position of the hoisting member 3, thereby ensuring the stability and safety during hoisting.

[0042] In some embodiments of the present utility model, the hoisting structure further includes an adjusting assembly.

The lifting ring 30 is connected to the adjusting nut 40 through the screw rod 31 passing through the adjusting hole 2012. During hoisting, if there is a phenomenon of gravity offset, the position of the adjusting nut 40 can be adjusted to adjust the hoisting position. The appropriate position of the lifting ring 30 can be adjusted according to different layouts inside the cabinet body 6 to ensure the stability of the center of gravity during hoisting, thereby ensuring the smoothness and safety of hoisting.

[0043] In some embodiments of the present utility model, the connecting member 20 includes a connecting member body. The cross-sectional shape of the connecting member body is U-shaped. The connecting member body includes a first wing plate 200 and a second wing plate 201 that are perpendicular to each other and of an integral structure.

[0045] In some embodiments of the utility model, the support member 5 further includes a limit plate 53, and the number of the limit plates 53 is two. The two limit plates 53 are respectively arranged on both sides of the support plate 50, and the distance between the limit plates 53 is greater than the minimum outer diameter of the adjusting nut 40 and less than the maximum outer diameter of the adjusting nut 40. Specifically, the two limit plates 53 are vertically arranged on both sides of the support plate 50, and the height of the limit plates 53 is the same as the height of the connecting plate 51. By setting two limit plates 53, the adjusting nut 40 can be limited, and the distance between the limit plates 53 is greater than the minimum outer diameter of the adjusting nut 40 and less than the maximum outer diameter of the adjusting nut 40. While ensuring that the adjusting nut 40 can move in the adjusting space 52 along the length direction of the support plate 50, the adjusting nut 40 is prevented from rotating in the adjusting space 52 when the lifting ring 30 is installed, which facilitates the installation of the lifting ring 30.
