[0052] (2) Refer to Figure 2 When the transport rack needs to transport a medium battery pack, all the bolts on the transport rack are also disassembled, first twist all the bolts on the transport rack to make the corner frame, sleeve and pipe frame on the transport rack lose the limiting between them, and the eighth bolt and the ninth bolt are completely twisted off, the four second connecting rods 22 and the four first connecting rods 21 on the rack are disassembled, according to the size range of the medium battery pack, the four second connecting rods 22 and the four first connecting rods 21 which are one size smaller are replaced and reinstalled on the rack, according to the model and size of the medium battery pack, the positions between the middle corner frame 1, the first pipe frame 3, the second pipe frame 4, the first sleeve 2, the second sleeve 9, the third sleeve 10, the movable inner pipe 11, the first connecting rod 21, the second connecting rod 22, the first corner frame 5, the second corner frame 6, the third corner frame 7, the fourth corner frame 8, the first frame 13 and the second frame 14 are adjusted, after the positions are adjusted, according to the re-adjusted positions, all the bolts are installed to fix the corner frame, sleeve and pipe frame on the transport rack, thus according to the model of the medium battery pack, the range of use of the transport rack for the medium battery pack can be adjusted, the effect of the transport rack for the medium battery pack is ensured, the range of the medium transport rack which can be adjusted is that the length can be adjusted between 1800 and 2400, the width can be adjusted between 1400 and 1800, as long as the volume of the object is in this range interval, the medium transport rack can be used to transport the object.

[0053] (3) Refer to Figure 3When the transport rack needs to transport small battery packs, all the bolts on the transport rack are also disassembled. First, all the bolts on the transport rack are screwed to make the angle frame, sleeve and pipe frame on the transport rack lose the limit, and all the angle frame, sleeve and pipe frame on the rack are disassembled and reassembled. Because small battery packs do not need many angle frames, sleeves and pipe frames, when all the angle frames, sleeves and pipe frames are disassembled, first, two movable inner tubes 11 are taken to insert the first angle frame 5 and the second angle frame 6 together, two movable inner tubes 11 are taken to insert the third angle frame 7 and the fourth angle frame 8 together, one movable inner tube 11 is taken to insert the first angle frame 5 and the third angle frame 7 together, and another movable inner tube 11 is taken to insert the second angle frame 6 and the fourth angle frame 8 together. Finally, according to the size range of the small battery pack, replace a second connecting rod 22 and a first connecting rod 21 of appropriate size for installation, and cross the second connecting rod 22 and the first connecting rod 21 respectively installed on the first limiting frame 17 of the first angle frame 5, the second angle frame 6, the third angle frame 7 and the fourth angle frame 8, thereby forming a small transport rack. According to the size of the small battery pack, adjust the position between the first angle frame 5, the second angle frame 6, the third angle frame 7, the fourth angle frame 8, the six movable inner tubes 11, the second connecting rod 22 and the first connecting rod 21. After the position is adjusted, all the bolts are installed according to the re-adjusted position to fix the angle frame and the sleeve on the transport rack. Thus, the use of the transport rack for small battery packs can be adjusted to improve the range of use of the transport rack for small battery packs and ensure the effect of transporting small battery packs by the transport rack. The range of such small transport racks can be adjusted to a length of 1400 to 1700 and a width of 1200 to 1400. In addition to battery packs, any item with a size within this range can be transported using this small transport rack.

[0054] (4) Refer to Figures 1-3 , by setting the sled frame 12 to facilitate the forklift transporting the specified size of the transport rack, and at the same time, the sled frame 12 can limit the transport rack on the forklift through the shape of the sled frame 12 when the forklift transports the transport rack, avoiding the transport rack from falling off the forklift when the forklift transports the transport rack, ensuring the effect of transporting the transport rack by the forklift. Because the first pipe frame 3, the second pipe frame 4, the first frame 13 and the second frame 14 are connected by connecting bolts respectively with the four sled frames 12, the four sled frames 12 are disassembled and replaced, and the four sled frames 12 are installed on the small transport rack, so the four sled frames 12 can be installed on the four movable inner tubes 11 on the outside of the small transport rack. Therefore, the four sled frames 12 can replace the specified size of the sled frame 12 according to the size of the large transport rack, the medium transport rack and the small transport rack, to ensure the effect of transporting the specified size of the transport rack by the forklift.

[0055] (5) Refer to Figure 4 and Figure 5 The four corners of the battery pack on the transport rack can be limited by the four movable sleeves 16 and the four fixed feet 15, which can avoid the phenomenon of shaking or deviation of the battery pack during transportation of the transport rack, and can prevent the battery pack from falling off the transport rack. When the height of the four movable sleeves 16 needs to be adjusted, the movable bolts on the four fixed feet 15 are first disassembled, so that the four movable sleeves 16 lose the limitation on the four fixed feet 15, and then the height of the four movable sleeves 16 is adjusted. The height of the movable sleeve 16 can be adjusted according to the height of the battery pack and the height of the stacked battery packs on the transport rack. After the height adjustment of the movable sleeve 16 is completed, the four movable sleeves 16 are fixed on the four fixed feet 15 by installing the four movable bolts, and the four movable sleeves 16 can be fixed at the specified height. Therefore, the four movable sleeves 16 can be adjusted according to the height of the battery pack and the height of the stacked battery packs on the transport rack, so that the four fixed feet 15 and the movable sleeves 16 can limit and fix the stacked battery packs on the transport rack, which can further enhance the range and effect of the transport rack for the battery pack.
