[0002] Freight transportation is one of the main modes of modern transportation and one of the two basic modes of land freight transportation. It occupies an important position in the entire transportation field and plays an increasingly important role. Freight transportation is less affected by climate and natural conditions, and has a large transportation capacity and single vehicle loading capacity. It has advantages in terms of regularity and low cost of transportation. In addition, there are many types of vehicles, which makes it possible to carry almost any goods without being restricted by weight and volume, which are incomparable to road and air transportation.

[0003] At present, in the process of transporting columnar goods (such as pipes, coils, etc.), two groups of methods are generally adopted, namely vertical loading and horizontal loading. Vertical loading is to place the central axis of the goods perpendicular to the bottom of the vehicle. This loading method is stable and safe, so it is more commonly used. However, when the length of the goods is greater than its diameter, the horizontal loading method must be adopted. However, the horizontal loading method is to place the central axis of the goods parallel to the bottom of the transportation equipment. This loading method has poor safety and the goods may roll. If sudden braking, bumps, etc. occur during transportation, there are great safety hazards. In order to improve the safety of columnar freight transportation, the prior art discloses a fixing device that needs to be used to clamp and limit the columnar goods. However, these fixing devices often have fixed dimensions and specifications, and cannot be adaptively adjusted according to the length and diameter of the columnar goods. They have poor versatility and cannot meet the transportation needs of columnar goods. Utility Model Content
