[0027] Multiple limiting groups are arranged along the length direction of long beam 100. Each limiting group includes two limiting portions, which are symmetrically arranged at both ends of long beam 100, and have a fixed spacing between the two limiting portions. The spacing of different limiting groups is different to adapt to electric core modules of different lengths. Specifically, as shown in the drawings, Figure 1As shown, in the specific embodiment, the lifting tool includes three sets of limiting groups, namely a first limiting group 110, a second limiting group 120, and a third limiting group 130.

The first limiting group 110 is suitable for lifting a short-size battery cell module 200, the second limiting group 120 is suitable for lifting a medium-size battery cell module 200, and the third limiting group 130 is suitable for lifting a long-size battery cell module 200.

[0028] In the specific embodiment, the limiting part includes two limiting blocks and a limiting pressing plate. Taking the first limiting part 111 as an example, the first limiting part 111 includes two limiting blocks 114 and one limiting pressing plate 115.

[0029] The limiting block 114 is arranged on the surface of the long beam 100, and the two limiting blocks 114 are arranged at intervals in the length direction of the long beam 100, and have a gap therebetween. In one specific embodiment, the limiting block 114 is welded on the surface of the long beam 100. In another specific embodiment, the limiting block 114 can be detachably fixed on the surface of the long beam 100 by bolts.

[0030] The limiting pressing plate 115 can be detachably fixed on the surface of the two limiting blocks 114 away from the long beam 100. In one specific embodiment, the limiting pressing plate 115 is detachably fixed on the surface of the limiting block 114 away from the long beam 100 by bolts, and in another specific embodiment, the limiting pressing plate 115 can be connected with the limiting block 114 by a quick locking mechanism, facilitating quick disassembly and assembly.

[0031] The limiting block 114, the limiting pressing plate 115, and the long beam 100 form a limiting groove, and the fixed end 141 of the lifting hook 140 can be arranged in the limiting groove. The size of the limiting groove is slightly larger than the size of the fixed end 141 of the lifting hook 140, so that the fixed end 141 of the lifting hook 140 can be embedded in the limiting groove.

[0032] The lifting tool comprises two lifting hooks 140 selectively mounted on the limiting parts of one limiting group. For example, when a long-size battery cell module 200 needs to be lifted, two lifting hooks 140 are respectively mounted on two third limiting parts 131 of the third limiting group 130; when a medium-size battery cell module 200 needs to be lifted, two lifting hooks 140 are respectively mounted on two second limiting parts 121 of the second limiting group 120; when a short-size battery cell module 200 needs to be lifted, two lifting hooks 140 are respectively mounted on two first limiting parts 111 of the first limiting group 110.

[0033] The lifting hook 140 comprises a fixed end 141 arranged in the limiting part and a hook-shaped end 142 away from the fixed end 141 and used for connecting with the battery cell module 200. The fixed end 141 of the lifting hook 140 is arranged in the limiting groove for limiting the position of the lifting hook 140; the hook-shaped end 142 of the lifting hook 140 is used for connecting with the battery cell module 200 to be lifted. In the specific embodiment, the lifting hook 140 is a double-hook structure formed by bending a reinforcing bar, the bending part of the reinforcing bar is the fixed end 141, and the two ends of the reinforcing bar are respectively bent into hooks as the hook-shaped end 142. When the battery cell module 200 is lifted, the left and right hooks can be clamped into the end plate of the battery cell module 200 to realize the lifting and placing of the battery cell module 200. In some specific embodiments, the double-hook structure is suitable for the working condition that the lifting space is large and the weight of the lifted module is large.

[0034] In another specific embodiment, as shown in Figure 3 and Figure 4 , wherein, Figure 3 is a schematic diagram of another specific embodiment of the lifting tool of the utility model suitable for battery cell modules 200 of multiple lengths, Figure 4is another schematic view of the lifting tool for lifting the battery cell module 200 of the present application, the lifting hook 140 is a single hook structure formed by bending a reinforcing bar, one end of the reinforcing bar is bent as the fixed end 141, the other end of the reinforcing bar is bent into a hook as the hook-shaped end 142. For example, a reinforcing bar is bent into an upper rectangular frame with a bottom extended hook structure, the bottom hook structure is made of forging bending process, the upper rectangular frame is the fixed end 141, and the bottom hook structure is the hook-shaped end 142. When lifting the battery cell module 200, the hook-shaped end 142 passes through the triangular hole on the top of the end plate of the battery cell module 200 and is clamped into the lifting lug hole of the end plate, so that the battery cell module 200 can be lifted. In some embodiments, the single hook structure is suitable for the working condition that there is no external lifting space outside the space of the battery cell module 200 and the weight of the battery cell module 200 is relatively light.

[0035] Further, in some embodiments, the hook-shaped end 142 has an insulating layer (not shown in the figure), so that the hook-shaped end 142 of the lifting hook 140 is insulated from the battery cell module 200 after contacting the battery cell module 200, thereby avoiding the risk of short circuit. In another embodiment, the insulating layer is not provided, but the hook-shaped end 142 of the lifting hook 140 is connected with the insulating material area of the battery cell module 200, thereby avoiding the risk of short circuit.

[0036] Further, in one embodiment, as shown in Figure 1 the hook-shaped ends 142 of the two lifting hooks 140 are bent in opposite directions, that is, the hook-shaped ends 142 of the two lifting hooks 140 are bent towards the center of the lifting tool, and when the battery cell module 200 needs to be lifted, the hook-shaped ends 142 of the two lifting hooks 140 are clamped into the end plate of the battery cell module 200 to realize the connection with the battery cell module 200.

[0037] In some embodiments, the lifting function needs to be realized by expanding the lifting space (i.e. adding a lifting structure or expanding the operation area outside the battery cell module 200), for example, as shown in Figure 1 and Figure 2The hook-shaped ends 142 of the two lifting hooks 140 are folded towards the outside of the lifting tool, and the hook-shaped ends 142 of the lifting hooks 140 are connected to the battery cell module 200 from the inside of the outer contour of the battery cell module 200, thereby solving the problem of needing to expand the lifting space to realize the lifting function. Specifically, in this embodiment, the hook-shaped ends 142 of the two lifting hooks 140 are folded away from each other, that is, the hook-shaped ends 142 of the two lifting hooks 140 are folded towards the outside of the lifting tool. When the battery cell module 200 needs to be lifted, the hook-shaped ends 142 of the two lifting hooks 140 pass through the triangular holes at the top of the end plates of the battery cell module 200 and are clamped into the lifting lug holes of the end plates, thereby realizing connection with the battery cell module 200. In the process of lifting the container, no additional lifting space in the length direction of the battery cell module 200 needs to be reserved.

[0038] In some embodiments, as shown in Figure 3 and Figure 4 The hook-shaped ends 142 of the lifting hooks 140 are folded towards the outside of the lifting tool, and the hook-shaped ends 142 of the lifting hooks 140 are connected to the battery cell module 200 from the inside of the outer contour of the battery cell module 200, thereby solving the problem of needing to expand the lifting space to realize the lifting function. Specifically, in this embodiment, the hook-shaped ends 142 of the two lifting hooks 140 are folded away from each other, that is, the hook-shaped ends 142 of the two lifting hooks 140 are folded towards the outside of the lifting tool. When the battery cell module 200 needs to be lifted, the hook-shaped ends 142 of the two lifting hooks 140 pass through the triangular holes at the top of the end plates of the battery cell module 200 and are clamped into the lifting lug holes of the end plates, thereby realizing connection with the battery cell module 200. In the process of lifting the container, no additional lifting space in the length direction of the battery cell module 200 needs to be reserved.

[0039] In some embodiments, as shown in Figure 1 The lifting tool further comprises at least two lifting rings 150, which are detachably fixed on the long beam 100. The lifting ring 150 can be detachably fixed on the long beam 100 by bolts. The lifting ring 150 is used to connect with external lifting equipment (such as a crane) to realize the lifting operation of the battery cell module.

[0040] When the battery cell module 200 is lifted by the lifting tool of the present application, the hook type can be selected according to the working condition requirements and clamped into the limiting groove with a length suitable for the battery cell module 200. Then, the limiting pressing plate 115 is locked, and the lifting rope of the traveling crane is hung on the lifting hook of the traveling crane after passing through the lifting ring 150. Finally, the lifting hook 140 is clamped into the end plate of the battery cell, or is clamped into the lifting lug hole of the left and right end plates of the battery cell module 200. The battery cell module 200 can be transferred to a specific position by starting the traveling crane. It should be noted that the length of the lifting rope passing through the left and right lifting rings 150 should be adjusted to be consistent, otherwise it is easy to cause the module to rotate and hurt people during lifting.

[0041] The utility model discloses a lifting tool can adapt to the different length's electric core module, improve tool versatility, promote the operation efficiency, and simple structure, low manufacturing cost, high mechanical stability.
