[0001] The present invention relates to the technical field of warehousing and freight transportation, and in particular to a fork tooling for a freight forklift and a battery pack adapted to the fork-mounted tooling, a forklift, and a transportation method. Background Art

[0002] With the transformation of energy structure and the rapid development of renewable energy, the application of energy storage systems is becoming more and more abundant, so the shipment volume is also growing. These energy storage systems are generally composed of dozens or even hundreds of battery packs, so during the production and maintenance of energy storage systems, it is necessary to frequently move a large number of battery packs.

[0003] At present, the battery pack handling tools commonly used by enterprises, such as general-purpose forklifts or stackers, have flat forks and a certain thickness. They usually need to be used with pallets to fork load goods. Therefore, in this process, the pallet plays the role of raising and carrying the stacked goods, so that traditional forks can be inserted from the pallet receiving interface to lift the goods for transportation. Therefore, the pallet itself not only occupies the freight space on the handling tool, but the handling tool is also limited by the shape of the pallet during transportation. Because the specifications of goods such as battery packs are usually much smaller than the pallet itself, the size of the pallet needs to be taken into account when transporting and loading and unloading goods, leaving a larger space for maneuvering. This places high demands on the storage environment and the skills of freight drivers.

[0004] It can be seen that the existing forklift-type transportation tools combined with pallet freight methods have many limitations, which have seriously hindered the handling efficiency of battery packs. Summary of the invention

And one or more of the components in the diagram may be necessary or non-essential, and the relative position relationship between the components in the above diagram can be adjusted according to actual needs.

[0040] In order to save the pallet in the process of fork loading the battery pack 9 and improve the handling efficiency of the battery pack 9, as shown in FIG. Figures 1 to 6 As shown, the present invention provides a fork tooling, which preferably includes: a forklift frame 1, a tooth plate 2, an adjustment member 3, and a fork tooth member 4. Figure 1 to Figure 2 As shown, the forklift frame 1 is provided with an upper slot frame 11 and a lower slot frame 12 in parallel and at intervals, wherein the slots 13 of the upper slot frame 11 and the lower slot frame 12 are as shown in FIG. Figure 5 As shown in the figure, they are arranged in opposite directions, and the upper slot frame 11 is also provided with a plurality of Figure 2 , Figure 4 The positioning opening 14 shown in the figure can provide a unit stepping distance for the subsequent adjustment of the spacing of the fork teeth 4. The tooth plate 2 is provided with an upper hook 21 and a lower hook 22. One end of the adjustment member 3 is provided with a limiting arm 31. The limiting arm 31 is as shown in FIG. Figure 3 As shown, it is in a curved shape, the other end of the adjusting member 3 is connected to the toothed plate 2, and the fork tooth member 4 is vertically arranged horizontally, and its tail is connected to the toothed plate 2.

[0041] With this arrangement, when a pair of the toothed plates 2 are respectively hooked into the slots 13 of the upper slot frame 11 and the lower slot frame 12 of the forklift frame 1 through the upper hook 21 and the lower hook 22 to form a hook connection, they can be translated in the slots 13 to freely adjust the distance between each toothed plate 2, and then the limiting arm 31 of the adjustment member 3 is engaged with the positioning port 14 to limit the toothed plate 2 and complete the adjustment and fixation of the spacing between the fork teeth 4, which is best prepared for the subsequent fork-mounted adapted battery pack 9.

[0042] In addition, in order to ensure the stability of the clamping of the limit arm 31 and the positioning opening 14, the positioning openings 14 on the upper slot frame 11 are actually arranged at a limited density and cannot be densely arranged to improve the adjustment accuracy, thereby limiting the adjustment freedom of the toothed plate 2, thereby affecting the minimum adjustment accuracy of the position of the fork teeth 4. Therefore, in order to achieve fine adjustment of the spacing between the fork teeth 4, as shown in FIG. Figure 2 , Figure 4 As shown, in an optional embodiment, a waist hole 32 is provided on the adjustment member 3, and the length of the waist hole 32 is greater than or equal to the spacing of the positioning openings 14 to span the unit step distance. The tooth plate 2 is matched with the waist hole 32 through an adjusting bolt to freely adjust the relative distance between the limit arm 31 and the tooth plate 2 between adjacent positioning openings 14, thereby realizing precise adjustment of the spacing between the fork teeth 4.

[0043] Furthermore, in order to facilitate the rapid assembly and disassembly of the toothed plate 2, as shown in FIG. Figure 1 , Figure 2 , Figure 4 As shown, in an optional embodiment, the lower trough frame 12 is provided with a crossing 15 near the center position, and the crossing 15 is connected to the notch 13 of the lower trough frame 12, and the toothed plate 2 is as shown in FIG. Figure 6 As shown, the upper hook 21 is in the form of a lower hook, and the lower hook 22 is in the form of an upper hook. With this arrangement, the toothed plate 2 is extended into the crossing 15 by the lower hook 22 and then lifted up, so that the upper hook 21 can be first hooked into the notch 13 of the upper slot frame 11, and then dropped and translated along with the trend, and then the lower hook 22 is hooked with the lower slot frame 12, thereby completing the longitudinal limit of the toothed plate 2, and only allowing the toothed plate 2 to translate in the notch 13, thereby completing the rapid installation of the toothed plate 2 and the upper and lower slot frames 11, 12.

[0044] When removing the toothed plate 2, the reverse operation is sufficient, thereby the toothed plate 2 and the upper and lower trough frames 11 and 12 can be quickly removed through the crossing 15 without removing the upper hook 21 / lower hook 22, so as to facilitate subsequent maintenance and debugging during use.

[0045] On the other hand, corresponding to the above-mentioned fork tooling example, in order to adapt to its fork mounting, such as Figures 7 to 9 As shown, the present invention also provides a battery pack 9, specifically, as Figure 7 As shown, fork frames 91 are provided on both sides of the battery pack 9, and tooth holes 92 for forking with the fork teeth 4 are provided on the front side of the fork frames 91. With this arrangement, when the fork tooling of the above example is assembled on a forklift, the spacing between the fork teeth 4 is adjusted, such as Figure 8 As shown, the tooth holes 92 can be vertically inserted from both sides of the battery pack 9 to complete the fork installation of the battery pack 9.

[0046] Through the fork tooling of the above example and the fork loading of the battery pack 9 of this example, not only can the pallet be omitted and the battery pack 9 can be directly forked, but also, since the fork teeth 4 of this example are set to be vertically horizontal, it is different from the traditional fork form of lifting goods horizontally, and the battery pack 9 can be lifted from both sides and limited by the fork teeth 4 on both sides, without worrying about the risk of the battery pack 9 sliding horizontally. In addition, the vertically horizontal fork teeth 4 also further allows the forklift to only consider the size of the forked goods, which greatly reduces the restrictions on the environmental space requirements during the freight process compared to the pallet fork loading.

[0047] In addition, it is worth mentioning that in the stacked state of the battery pack 9 structure of this example, the battery pack 9 at the bottom actually replaces the role of the traditional pallet, so the cargo capacity during transportation can be further increased. At the same time, since the traditional fork is inserted from the bottom of the cargo, unless the cargo itself is raised, it cannot be inserted without the pallet, but the present invention does not have this limitation. When the fork teeth 4 of the fork tooling of the above example are lowered to the ground, the battery pack 9 can be forked from both sides without raising it, thereby eliminating many inconveniences and limitations of existing forks.

[0048] Furthermore, in order to facilitate the battery pack 9 to be suitable for hoisting and transportation, as Fig. 9 As shown, in an optional embodiment, the outer side of the fork frame 91 is further provided with hoisting holes 93. The hoisting holes 93 can be connected with the tooth holes 92 for hooking and pulling ropes during hoisting, thereby improving the diversity of the battery pack 9 that can be adapted to transportation.

[0049] On the other hand, in order to control the depth of the fork teeth 4 in the fork tooling of the above example when forking with the battery pack 9, as shown in FIG. Figure 3 , Figure 8 As shown, in an optional embodiment, the fork tine 4 may be provided with a stepped limiting portion 41 near the tail.

[0050] When the fork tine 4 is inserted into the tooth hole 92 of the battery pack 9, the limiting portion 41 abuts against the fork frame 91 of the battery pack 9, so as to limit the insertion depth of the fork tine 4 and provide a visual indication of the position, so as to facilitate workers' judgment and prevent the risk of goods falling during transportation due to insufficient insertion depth, or the risk of damaging the battery pack 9 due to excessive insertion depth, thereby improving the safety of fork-mounted transportation of the battery pack 9.

[0051] In addition, in order to facilitate fork loading, it is easier to align the fork teeth 4 with the tooth holes 92 of the battery pack 9 and insert them. Figure 3 As shown, in an optional embodiment, a guide portion 42 is provided at the top of the fork tine 4, and the guide portion 42 is in the shape of a gradually narrowing blade. Through this arrangement, the size difference between the tooth hole 92 and the top of the fork tine 4 can be enlarged, so as to reduce the difficulty of inserting the fork tine 4 into the tooth hole 92 and improve the fork installation efficiency.

[0052] On the other hand, corresponding to the above fork tooling example, Figure 1 As shown, the present invention further provides a forklift 8, which includes any of the fork attachments described above.

[0053] On the other hand, corresponding to the forklift 8 example, the present invention further provides a method for transporting a battery pack 9, which is used for the forklift 8 described in the above example to fork the battery pack 9 described in the above example, and the steps include:

[0054] Adjust the positioning opening 14 where the adjusting part 3 is clamped, adjust the toothed plate 2 and set the spacing between the fork teeth 4 to adapt to the spacing between the tooth holes 92 of the battery pack 9; control the forklift 8 to lift the forklift frame 1 to adjust the height of the fork teeth 4 to be flush with the tooth holes 92 of the battery pack 9; then control the forklift 8 to insert the fork teeth 4 into the tooth holes 92 of the battery pack 9 and then lift the forklift frame 1 until the battery pack 9 is off the ground and the fork loading is completed.

[0055] Furthermore, in an optional embodiment, the method for transporting the battery pack 9 further comprises the following steps:

[0056] To stack the battery packs 9 , the forklift 8 is controlled to insert the fork teeth 4 into the tooth holes 92 of the lowest battery pack 9 and then lift the forklift frame 1 until the lowest battery pack 9 is off the ground to complete the fork loading.

[0057] In summary, through the fork tooling and its adapted fork-mounted battery pack, forklift, and transportation method provided by the present invention, the fork tooling structure is cleverly designed so that the fork teeth 4 are vertically and horizontally arranged with adjustable spacing, so as to cooperate with the fork frames 91 set on both sides of the fork-mounted battery pack 9. During the transportation process, not only can the pallet be saved, the cargo capacity can be increased, and many limitations mentioned in the background technology can be eliminated, but the battery pack 9 can also be limited to avoid the risk of cargo slipping or falling, thereby effectively improving the transportation efficiency of the battery pack 9.
