[0002] A lowbed semi-trailer is a trailer with the axle placed behind the center of gravity of the vehicle and equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. It is usually used to transport heavy vehicles, mining machinery, and other heavy-loaded goods. The lower the center of gravity, the better the stability and safety, and the stronger the ability to transport extra-high cargo and pass overhead obstacles.

[0003] When transporting heavy objects with existing low-bed semi-trailers, the heavy objects are parked on the rear trailer of the semi-trailer, and a large number of tools such as straps are needed to assist in fixing them to prevent the heavy objects from shaking with the vehicle body during transportation. However, the fixing effect of tools such as straps is relatively general, and it is inevitable that the heavy objects will slide slightly relative to the trailer, which makes the safety during transportation need to be improved. At the same time, the fixing process of the straps is relatively troublesome and time-consuming.

[0022] In the specific implementation process, Figure 1 and Figure 2 As shown, a reinforcement frame 431 is fixedly connected to the abutment 43 .

[0023] It should be noted that the abutment 43 drives the reinforcement frame 431 to move closer to the goods, and the abutment 43 can be used to effectively limit the position of the goods to ensure that they are placed more stably on the anti-slip rubber pad 3.

[0025] It should be noted that the adjusting shaft 44 rotates, driving the threaded sleeve 51 to drive the abutment 43 to move accordingly, so that the sliding sleeve 5 at the other end of the abutment 43 can slide stably relative to the long rod 42 .

[0026] refer to Figure 1 and Figure 3As shown, a cavity is provided inside the vehicle body 1, and a transverse axis 7 is rotatably connected inside the cavity.
