[0044] Unless otherwise defined, all technical terms used in the embodiments of the present invention have the same meanings as commonly understood by those skilled in the art.

[0045] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0046] Combine Figure 1 and Figure 2 As shown, this embodiment provides a lifting device, which includes: a suspension rod 1 and two hook assemblies 2 , and the two hook assemblies 2 are movably located at both ends of the suspension rod 1 .

[0047] Each hook assembly 2 includes a sling part 21, a locking part 22 and a hook part 23; the sling part 21 is connected to the suspension rod part 1 and the locking part 22 respectively, the locking part 22 is connected to the hook part 23, and the hook part 23 is used to connect the objects to be lifted (not shown in the figure).

[0048] A first plastic coating 231 is formed on the surface of the hook 23 .

[0049] In the lifting device of this embodiment, two hook assemblies 2 are movably provided at both ends of the lifting rod 1. The hook assemblies 2 respectively include a sling part 21, a locking part 22 and a hook part 23. The hook part 23 is used to connect the object to be lifted. The surface of the hook part 23 is provided with a first plastic coating layer 231 with insulating properties. By connecting the hook part 23 with surface insulation to the object to be lifted, problems such as short circuit or sparks when the hook part 23 contacts or collides with the energy storage product can be avoided, which is conducive to improving the safety of lifting.

[0050] In addition, the hook assembly 2 is movably connected to the suspension rod 1. By adjusting the position of the hook assembly 2 on the suspension rod 1, it is possible to adapt to objects of different sizes to be lifted, thereby improving the adaptability of the lifting device.

[0051] Among them, the items to be lifted are energy storage products such as lithium batteries, battery modules, and power batteries. These products have risks such as short circuits or fire during production operations.

[0052] In some possible implementations, the interior of the hook member 23 comprises a hook body 232, and a first overmolded layer 231 covers the surface of the hook body 232. The first overmolded layer 231 is insulating, thereby ensuring insulated and secure contact with the object being hoisted, thereby improving the safe transportation of the object. For example, the hook member 23 has a circular cross-section, and the first overmolded layer 231 has an annular cross-section.

[0053] In some possible implementations, the sling 21 is made of a flexible insulating material.

[0054] In some possible implementations, two hook assemblies 2 are symmetrically arranged at both ends of the boom member 1, and a lifting structure (not shown) is provided in the middle of the boom member 1, which can be connected to a lifting device.

[0055] The lifting device of this embodiment can connect the two ends of the object to be lifted respectively through the hook members 23 of the two hook assemblies 2 to lift the object to be lifted stably.

[0056] Combine Figure 3 As shown, in some embodiments, the hook member 23 includes a frame 233 .

[0057] The frame 233 includes a first cantilever portion 2331 , a connecting portion 2334 , and a second cantilever portion 2332 , which are connected in sequence in a U-shape.

[0058] The first cantilever portion 2331 and the second cantilever portion 2332 are respectively provided with a hook portion 2333 at their cantilever ends; and the connecting portion 2334 is connected to the locking member 22 .

[0059] Through the above arrangement, the hook member 23 can use the two hook parts 2333 on the first cantilever part 2331 and the second cantilever part 2332 to respectively hook two positions on the same end of the object to be lifted. The two hook members 23, a total of four hook parts 2333, can provide four-point stable support for the object to be lifted. Therefore, using the hook member 23 of this embodiment, vertical and stable lifting of the object to be lifted can be achieved.

[0060] For example, the hook member 23 is formed by bending a round rib, and then a first plastic coating layer 231 is attached to the surface.

[0061] In some possible implementations, reference Figure 3 As shown, the plane where the first cantilever portion 2331 , the connecting portion 2334 and the second cantilever portion 2332 are located is parallel to the cross section of the suspension rod 1 .

[0062] Through the above arrangement, the hook member 23 as a whole is basically parallel to the cross-section of the lifting rod member 1. When the lifting device of this embodiment is used to connect the objects to be lifted, the two hook members 23 can be respectively arranged on the two end faces of the objects to be lifted that are parallel to the cross-section of the lifting rod member 1, providing four-point stable support for the objects to be lifted.

[0063] Combine Figure 3 As shown, in some embodiments, the hook member 23 further includes at least one reinforcing rib 234 , and the at least one reinforcing rib 234 is connected to the first cantilever portion 2331 and the second cantilever portion 2332 , respectively.

[0064] In order to improve the structural strength of the hook member 23 in this embodiment, at least one reinforcing rib 234 is arranged between the first cantilever portion 2331 and the second cantilever portion 2332, which is beneficial to improving the structural strength of the hook member 23 and further improving the working reliability of the lifting device.

[0065] Combine Figure 4 As shown, in some embodiments, a second overmolding layer 221 is provided on the surface of the locking member 22 .

[0066] In the lifting device of this embodiment, the locking member 22 serves as the connecting part between the hook member 23 and the sling member 21. When the sling member 21 is relatively fixed to the lifting rod member 1, the locking member 22 may need to be removed to release the hook member 23. During this process, the locking member 22 also has the risk of colliding with the object to be lifted. Therefore, by arranging a second plastic coating layer 221 on the surface of the locking member 22, the locking member 22 also has surface insulation, so that the locking member 22 itself, as well as the locking member 22 and the hook member 23 also have insulation, further improving the working reliability and safety of the lifting device.

[0067] In some possible implementations, the lock member 22 includes a lock body 222 and a latch body 223 . The lock body 222 is a U-shaped structure, and the latch body 223 is movably plugged into two cantilever ends of the lock body 222 .

[0068] When using the lifting device of this embodiment, first pull out the pin body 223, and pass one of the cantilever arms of the lock body 222 through the hook part 23 and the sling part 21 respectively. Then, plug the pin body 223 into place, and limit the hook part 23 and the sling part 21 in the U-shaped space of the lock body 222, so as to realize convenient connection of the sling part 21, the lock part 22 and the hook part 23.

[0069] Illustratively, the surfaces of the lock body 222 and the latch body 223 are both provided with a second plastic coating layer 221 , and the second plastic coating layer 221 has insulating properties, so that it can be insulated and safely contacted with the objects to be lifted, thereby improving the safe transportation of the objects to be lifted.

[0070] Combine Figure 5 As shown, in some embodiments, each hook assembly 2 further includes a fixing block 24 .

[0071] The fixing block 24 is connected to the suspender member 1 , and a groove structure 241 is provided on the outer wall of the fixing block 24 . The sling member 21 is located in the groove structure 241 , and at least part of the sling member 21 protrudes below the fixing block 24 to form a buckle portion 211 , which is used to connect the locking member 22 .

[0072] Through the above arrangement, the flexible sling part 21 can be clamped in the groove structure 241 of the fixed block 24. The fixed block 24 is connected to the suspension rod 1, and the sling part 21 protrudes to the bottom of the fixed block 24 to form a buckle part 211 for connecting the locking part 22. In this way, the position of the flexible sling part 21 can be fixed.

[0073] Combine Figure 5 As shown, in some embodiments, the fixing block 24 is provided with an assembly hole 242, and the assembly hole 242 is connected to the suspension rod 1. By using the assembly hole 242, the fixing block 24 can be passed through the suspension rod 1, the connection method is simple, and the connection reliability is higher.

[0074] Combine Figure 5 As shown, in some embodiments, the assembly hole 242 is a non-circular hole, the cross section of the suspension rod 1 is non-circular, and the shape of the cross section of the suspension rod 1 is the same as the shape of the assembly hole 242 .

[0075] Through the above arrangement, after the fixing block 24 and the suspension rod 1 are connected by the assembly hole 242, they cannot rotate in the circumferential direction, have better stability, and are conducive to improving the working reliability of the lifting device.

[0076] Exemplarily, the assembly hole 242 is a square hole or a rectangular hole, and the cross section of the suspension rod member 1 is a square cross section or a rectangular cross section.

[0077] Combine Figure 5 As shown, in some embodiments, a positioning bolt 243 is provided on the fixing block 24, and a plurality of positioning holes 11 are provided on the suspension rod 1. The positioning bolt 243 corresponds to the position of the positioning hole 11, and the positioning bolt 243 is connected to the positioning hole 11, which can limit the position of the fixing block 24 on the suspension rod 1.

[0078] For example, the plurality of positioning holes 11 are spaced apart along the axial direction of the lifting rod 1 , which can meet the size requirements of objects to be lifted of different sizes.

[0079] Through the above arrangement, the axial position of the fixing block 24 on the suspension rod 1 can be locked by using the positioning bolt 243 , thereby improving the relative position stability between the hook assembly 2 and the suspension rod 1 .

[0080] Combine Figure 5 As shown, in some embodiments, a quick wrench 244 is provided on the positioning bolt 243. The quick wrench 244 can be used to quickly screw the positioning bolt 243 to unlock or lock the position of the fixing block 24 on the boom member 1, thereby facilitating adjustment of the position of the hook assembly 2 on the boom member 1.

[0081] Combine Figure 5 and Figure 6 As shown, in some embodiments, each hook assembly 2 further includes a fixing cover 25 .

[0082] The fixing cover 25 is located on the outer wall of the fixing block 24 and covers the groove structure 241 . A notch 251 is provided at the lower portion of the fixing cover 25 . The notch 251 is used to allow the buckle portion 211 to extend downward.

[0083] In order to further improve the connection reliability between the sling 21 and the fixing block 24, a fixing cover 25 is covered on the groove structure 241 on the outer wall of the fixing block 24. The fixing cover 25 can fix the sling 21 in the groove structure 241 to prevent the sling 21 from escaping from the groove structure 241.

[0084] The lifting device provided in this embodiment has a hook member 23, a locking member 22 and a lifting belt member 21 which are all insulated and will not cause short circuit or electric spark problems when in contact with or colliding with energy storage products.

[0085] The sling member 21 is mounted and fixed on the suspender member 1 by means of a fixing block 24 and a fixing cover 25 , which increases reliability.

[0086] The fixing block 24 is connected to the hanger member 1 and can be quickly unlocked or locked using a quick wrench 244 and a positioning bolt 243. It can be quickly adjusted according to the size of the energy storage product, and has better work adaptability.
