Figures 1-2 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] (like Figure 1 As shown, a multi-functional lifting device for power batteries has a frame 1, and a multi-hole lifting lug 2 is provided at the center of the top of the frame 1.

[0028] In the above embodiment, as the preferred embodiment of the utility model: the frame 1 has a square frame 1.1, specifically, the square frame 1.1 of the frame 1 is made of four square steels by welding. The longitudinal and transverse I-shaped frame 1.2 is arranged at the middle of the inner side of the square frame 1.1, which realizes longitudinal and transverse strengthening support of the inner side of the square frame 1.1, improves the structural support stability of the square frame 1.1, and prevents the deformation of the square frame 1.1. The longitudinal and transverse I-shaped frame 1.2 is welded and fixed with the multi-hole lifting lug 2 at the center top end, which is reliable in connection and convenient for processing and manufacturing.

[0029] In the above embodiment, as the further improved embodiment of the utility model: the multi-hole lifting lug 2 has a plurality of hanging holes arranged in a horizontal line. The design of the plurality of hanging holes enables the lifting lug to select appropriate hanging point positions according to different hoisting requirements, which helps to optimize the hoisting scheme and improve the hoisting efficiency. The horizontally arranged hanging holes make it easier to connect and fix the sling or chain, reducing the complexity of operation. The plurality of hanging holes provide multiple stress points, which helps to disperse the concentrated stress during hoisting, thereby reducing the risk of damage to the hoist and hoisted object. By reasonably selecting the hanging hole position, the stability and balance of the hoisted object during hoisting can be ensured, and the safety hazards caused by shaking or tilting can be reduced. The horizontally arranged hanging holes make the installation process of the lifting lug more convenient and fast, and the operator can more easily connect and fix the sling or chain, reducing the installation time and cost. The multi-hole lifting lug 2 provided in the hoist, especially the design of the plurality of hanging holes arranged in a horizontal line, has significant technical advantages in enhancing hoisting flexibility, improving hoisting safety, adapting to different hoisting scenarios, and facilitating installation and maintenance.

[0030] The U-shaped fastening connector 3 is installed at the four end points of the long side of the frame 1. The U-shaped fastening connector 3 has reliable connection effect, can firmly connect each part of the frame 1 together to form a stable overall structure, which improves the anti-deformation and anti-overturning ability of the battery hoist during hoisting, ensuring the safe operation of hoisting.

[0031] In the above embodiments, as the preferred embodiment of the utility model: the U-shaped fastening connector 3 has a U-shaped rod 3.1, after the double rod bodies of the U-shaped rod 3.1 pass through the double holes made in the frame 1 and the steel plate 3.2 in turn, the double rod bodies are fastened and connected by using nuts 3.3 at the ends of the double rod bodies, so that the U-shaped fastening connector 3 and the frame 1 are detachably fastened and connected as a whole. The special shape of the U-shaped fastening connector 3 enables it to achieve a more compact connection effect, increasing the contact area of the connection part, thereby improving the strength and carrying capacity of the connection part, which means that the battery lifting appliance can bear greater weight and is suitable for hoisting larger and heavier battery packs. The installation and disassembly process of the U-shaped fastening connector 3 is relatively simple and does not require complex tools or professional skills. This design reduces the installation and disassembly cost of the battery lifting appliance, improves work efficiency, and also facilitates maintenance and repair of the battery lifting appliance, prolonging its service life. Furthermore, due to the detachable nature of the U-shaped fastening connector 3, the frame 1 of the battery lifting appliance can be adjusted according to battery packs of different sizes and weights. This design enables the battery lifting appliance to be suitable for various types and specifications of battery packs, improving its versatility and flexibility.

[0032] The U-shaped fastening connector 3 is connected to the top end of four lifting ropes 4 respectively; the bottom end of the four lifting ropes 4 is connected to the top end of four horse shoes 5 one by one. The cooperation of the four lifting ropes 4, the U-shaped fastening connector 3 and the horse shoes 5 forms a four-rope balanced hoisting system. This system realizes the stable hoisting of objects through four equal-length and uniformly stressed lifting ropes, which can ensure that the battery does not tilt or shake during hoisting, thereby improving the stability and safety of the hoisting operation. The horse shoes 5, as a kind of fastener, have the characteristics of compact structure and strong carrying capacity, and the connection of their top with the lifting ropes 4 can ensure that the shaking and impact of the battery during hoisting are effectively absorbed and dispersed, further enhancing the hoisting stability. The connection mode of the four lifting ropes 4, the U-shaped fastening connector 3 and the horse shoes 5 enables the stress in the hoisting process to be dispersed. This stress dispersion design can greatly improve the carrying capacity of the battery lifting appliance, enabling it to hoist heavier and larger battery packs. The design of the four-rope balanced hoisting system makes the hoisting operation more simple and efficient, and the operator only needs to adjust the length and tension of the lifting ropes 4 to realize the stable hoisting of the battery, reducing the operation difficulty and improving the work efficiency.

[0033] In the above embodiments, as the preferred embodiment of the utility model: the upper and lower ends of the lifting rope 4 are respectively provided with lifting rings, wherein the top end of the lifting rope 4 is sleeved with the U-shaped bottom end of the U-shaped fastening connecting piece 3, and the bottom end of the lifting rope 4 is sleeved with the top end of the horseshoe buckle 5. The design of the lifting rings at both ends of the lifting rope 4 makes the connection between the lifting rope and the U-shaped fastening connecting piece 3 and the horseshoe buckle 5 more firm and reliable. The lifting ring, as a special connecting component, has high strength and wear resistance, and can withstand a large tensile force, thereby ensuring the safety of the hoisting operation. The sleeving mode of the lifting ring makes the installation and disassembly process more simple and fast, and through the close cooperation of the lifting ring and the connecting piece, the shaking and tilting of the battery during hoisting can be effectively reduced. This stability is crucial to ensure the safe hoisting of the battery, especially when working in high altitude or complex environment. The design of the lifting rings at both ends of the lifting rope 4 makes the stress during hoisting more evenly distributed to each connecting component. This stress dispersion method can improve the carrying capacity of the entire hoisting system, enabling it to hoist heavier and larger size battery packs. The sleeving mode between the lifting ring and the U-shaped fastening connecting piece 3 and the horseshoe buckle 5 enhances the strength of the connecting part, ensuring that the connecting part will not break or loosen during hoisting, thereby ensuring the safe operation of the hoisting operation. The length of the lifting rope 4 can be adjusted as needed. This adjustability enables the battery lifting device to be applicable to battery packs of different sizes and weights, improving its versatility and flexibility.

[0034] The bottom end of each of the four horseshoe buckles 5 is connected to the top end of one of the four lifting hooks 6, and the hook body at the bottom end of each of the four lifting hooks 6 is inserted and fixed to one of the four lifting holes formed in the short side of the hanging plate 7. Through the corresponding connection of the four horseshoe buckles 5 and the four lifting hooks 6, and the insertion and fixation of the lifting hooks 6 and the four lifting holes on the hanging plate 7, a multi-point support structure is formed. This structure can more effectively distribute the stress during hoisting, improving the stability and carrying capacity of the overall structure. The multi-point connection design makes it difficult for the battery to shake or tilt during hoisting, thereby improving the stability and safety of the hoisting operation, which is crucial to ensure the safe transportation and storage of the battery. The insertion and fixation of the lifting hooks 6 and the lifting holes on the hanging plate 7 makes the connection process more simple and fast, not only improving the hoisting efficiency, but also making the battery lifting device more flexible and convenient when replacing the battery or adjusting the hoisting position. The insertion and fixation between the lifting hooks 6 and the lifting holes, as well as the close connection between the horseshoe buckles 5 and the lifting hooks 6, effectively prevent the battery from accidentally falling off during hoisting, which is crucial to the safety of the operator and the surrounding environment.

[0035] In the above embodiment, as the preferred embodiment of the utility model: the hook 6 is by welding and connecting as a whole hook connecting piece 6.1 and hook body 6.2 is composed of;The hook connecting piece 6.1 top end hangs and connects the bottom end of the horseshoe buckle 5;The hook connecting piece 6.1 bottom end welding and connecting hook body 6.2 top end;The hook body 6.2 is by the vertical portion and the bottom end bending portion of integrated molding is composed of;The bottom end bending portion inserts and connects the hanging hole made on the short side of hanging plate 7. The hook connecting piece 6.1 and the hook body 6.2 are connected by welding, which has high strength and stability, can withstand large tension, and ensures that the hook will not break or deform during hoisting. The hook body 6.2 is composed of a vertical portion and a bottom end bending portion, which reduces stress concentration points and improves the overall strength and durability of the hook body. The bottom end bending portion of the hook body 6.2 is inserted and fixed to the hanging hole made on the short side of the hanging plate 7. This insertion method makes the connection between the hook and the hanging plate more secure and reliable, and is not easy to loosen.

[0036] In the above embodiment, as the further improved embodiment of the utility model: the hook 6 is externally provided with an anti-abrasion layer. The anti-abrasion layer, such as wear-resistant rubber, fine steel wire interlocking structure or steel pipe sleeve, can effectively prevent direct abrasion of the hook. This anti-abrasion layer can significantly reduce abrasion caused by friction, thereby prolonging the service life of the hook. In the long-term high-strength and heavy-load working environment, the neck of the hook is prone to deformation, cracking and surface hardness change. The anti-abrasion layer not only reduces abrasion, but also protects the structural integrity of the hook to some extent, preventing the hook from failing due to abrasion. The application of the anti-abrasion layer can reduce the risk of safety accidents such as falling of the hoisted object caused by abrasion of the hook, thereby improving the safety of hoisting operations.

[0037] In the above embodiment, as the preferred embodiment of the utility model: the anti-abrasion layer is nylon PA66.
