The lower bracket 1 includes: a base 10 and several lower columns 11 welded to the base 10. In this embodiment, the number of lower columns 11 is four. The base 10 includes: a first profile frame 100, a second profile frame 101, and a first support frame 102 and a second support frame 103 disposed between the first profile frame 100 and the second profile frame 101. The first profile frame 100 and the second profile frame 101 are arranged in parallel, and the first support frame 102 and the second support frame 103 are arranged in parallel. The first support frame 102 and the second support frame 103 are respectively arranged perpendicular to the first profile frame 100 and the second profile frame 101. A first limiting brace 104 is provided between the first support frame 102 and the lower column 11, and a second limiting brace 105 is provided between the second support frame 103 and the lower column 11. The lower wheelset 2 is placed inside the lower bracket 1. One wheel 20 of the lower wheelset 2 is supported on the first support frame 102 and limited by the first limiting brace 104, while the other wheel 21 of the lower wheelset 2 is supported on the second support frame 103 and limited by the second limiting brace 105. The lower bracket 1 is provided with a first lifting lug 12, and the lower wheelset 2 is connected to the first lifting lug 12 by a first binding rope (not shown). Both the first profile frame 100 and the second profile frame 101 are provided with forkholes 13 to facilitate forklift operation. The base 10 of the lower bracket 1 is provided with at least one first reinforcing frame 14 between the first profile frame 100 and the second profile frame 101 to increase its structural strength. A third connecting frame 15 is provided between the two lower columns 11. A fourth connecting frame 16 is provided between the lower column 11 and the first profile frame 101. A fifth connecting frame (not shown) is provided between the lower column 11 and the second profile frame 101. Therefore, it has high structural strength.

[0023] The upper bracket 3 includes a third support frame 30, a fourth support frame 31, a first connecting frame 32, a second connecting frame 33, and several upper columns 34. In this embodiment, the number of upper columns 34 is four. A third limiting brace 35 is provided between the third support frame 30 and the upper column 34, and a fourth limiting brace 36 is provided between the fourth support frame 31 and the upper column 34. The upper wheelset 4 is placed inside the upper bracket 3. One wheel 40 of the upper wheelset 4 is supported on the third support frame 30 and limited by the third limiting brace 35. The other wheel 41 of the upper wheelset 4 is supported on the fourth support frame 31 and limited by the fourth limiting brace 36. The upper bracket 3 and the lower bracket 1 are connected by a connecting plate 5 and a fixing member 6. In this embodiment, there are four connecting plates. One end of two connecting plates is connected to the third support frame 30 of the upper bracket 3 by bolts, and the other end is connected to the lower column 11 by bolts. One end of the other two connecting plates is connected to the fourth support frame 31 of the upper bracket 3 by bolts, and the other end is connected to the lower column 11 by bolts. The mounting holes 50 on the connecting plate 5 that mate with the bolts are elongated holes, which reduces the difficulty of installation. The upper column 34 and the lower column 11 are connected by a sleeve 7. In this embodiment, the sleeve 7 is welded to the bottom of the upper column 34. Of course, in other embodiments, the sleeve 7 can also be welded to the top of the lower column 11, which can also achieve the present invention. The upper bracket 3 is provided with a second lifting lug 8, and the upper wheel set 4 is connected to the second lifting lug 8 by a second binding rope (not shown). At least one second reinforcing frame 37 is also provided between the first connecting frame 32 and the second connecting frame 33 of the upper bracket 3 to increase its structural strength. A sixth connecting frame 38 is provided between the upper column 34 and the first connecting frame 32, and a seventh connecting frame 39 is provided between the upper column 34 and the second connecting frame 33.

[0024] The upper wheelset 4 is equipped with an upper brake disc 42, and the lower wheelset 2 is equipped with a lower brake disc 22. The upper brake disc 42 and the lower brake disc 22 are staggered, thereby balancing the left and right weight of the entire wheelset packaging assembly and preventing tilting and tipping due to left and right weight imbalance during forklift lifting. The parts of the upper bracket 3 and lower bracket 1 that contact the wheels are covered with rubber (not shown), which can effectively protect the wheels during transportation. The upper bracket 3 and lower bracket 1 in this utility model are both made of steel, so the structure has high strength, replacing the existing wooden pad packaging and solving the problems of insufficient load-bearing capacity and easy corrosion of wooden pads during long-distance transportation.

[0025] In summary, the stackable wheelset packaging assembly of this utility model forms a two-layer stacked structure of two sets of wheelsets through the lower bracket 1 and the upper bracket 3. This not only facilitates transportation but also avoids collisions between the brake disc and the wheelset during transportation. Compared with the prior art, this utility model eliminates the base structure design of the lower bracket in the prior art, allowing the first profile frame 100 and the second profile frame 101 of the base 10 of the lower bracket 1 to be directly supported inside the container. This reduces the height of the entire wheelset packaging assembly and saves space. Therefore, the improved structure is applicable to large-diameter wheelsets. In this utility model, the upper bracket 3 and the lower bracket 1 are connected by a sleeve 7 and a connecting plate 5, which not only provides high connection strength but also makes assembly and disassembly convenient.

[0026] The above embodiments are merely illustrative of the principles and effects of this utility model, as well as some of its applications, and are not intended to limit this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
