The platform is bolted to the triangular connecting plate, that is, the platform adopts a detachable design, and different sizes of platform can be installed to change the load-bearing area.

[0007] Side support beams are fixedly installed on both sides of the fixed positioning rod. The tops of the side support beams are inclined towards both sides of the fixed positioning rod and are fixedly connected to the loading platform. The side support beams further and effectively transfer the load of the loading platform to the fixed positioning rod.

[0008] The fixed positioning rods are radially connected by inter-rod reinforcement beams to strengthen the connection strength between the fixed positioning rods.

[0009] A reinforcing plate is provided on the intermediate crossbeam corresponding to the fixed positioning rod. The upper end of the reinforcing plate is fixedly connected to the intermediate crossbeam, and the lower end is fixedly connected to the fixed positioning rod, thereby further enhancing the connection between the intermediate crossbeam and the fixed positioning rod.

[0010] The fixed positioning rod has pin holes spaced apart at one end for connecting with the semi-trailer; the load-bearing area is adjusted by connecting with the semi-trailer through the pin holes in different positions.

[0011] The symmetrical support beam is provided with a push-pull handle for moving the pull-out platform structure on the side away from the pin hole.

[0012] Secondly, this application also provides a semi-trailer, including a cargo platform, on which a pull-out plate frame beam is provided, and the pull-out plate frame beam has several mounting through holes on its side, the mounting through holes being used to connect and install the above-mentioned pull-out plate platform structure.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] A pull-out platform frame beam is installed on the cargo platform of the semi-trailer. The pull-out platform structure with a suitable load-bearing area is selected on the pull-out platform frame beam according to the goods to be transported, so as to adapt to different cargo requirements. Furthermore, when the goods are transported and the truck is returned empty, the pull-out platform structure can be removed to save transportation costs and reduce transportation expenses.
