[0002] Under the background of the country's strong promotion of the development of the photovoltaic industry, large-scale onshore and offshore photovoltaic projects are increasing day by day. Photovoltaic panels are placed on the sea surface through large truss structures. In the actual construction process, the construction of large offshore truss structures faces many challenges.

[0003] Due to the limited site for on-site assembly operations, the construction space is insufficient, seriously affecting the construction progress. At the same time, the high danger and complex construction difficulty during the construction process also bring great pressure to the operators. Usually, in order to improve the construction efficiency and ensure the construction quality, large truss structures are assembled in the prefabrication yard, and then transported to the construction site by land transport vehicles and offshore floating ships, and then hoisted into place as a whole.

[0004] However, large truss structures themselves have the characteristics of large structural dimensions, large flexibility, and easy deformation, which bring great difficulties in the land transportation link. During transportation, multiple flatbed transport vehicles need to work together, but only the four support point positions of the truss structure are in effective contact with the supporting transport vehicles, making it difficult to effectively fix the truss structure and effectively protect the finished truss. Content of the Utility Model

[0005] In view of the above technical problems, the utility model provides a tooling for truss transportation.
