Transfer trailer of hot steel billet

The utility model provides a transfer trailer of a hot steel billet, which comprises a trailer body, a steering device, automatic coupling devices and a brake system, wherein the trailer body is composed of a thermal insulation load workbench and a trailer frame, the thermal insulation load workbench is arranged on the trailer frame, and both ends of the trailer frame are both provided with the automatic coupling devices. The steering device is composed of a front and a back steering bridges and a steering link mechanism, the front and the back steering bridges are arranged in a symmetry mode and are arranged at the front and the back parts of the trailer frame through rotary disks, the steering link mechanism is formed by combining two groups of positive four-link mechanisms and one group of negative four-link mechanism, and the brake system is arranged on the trailer frame. The utility model adopts the automatic double-surface coupling and the front and the back steering bridges, so the steering radius is decreased, the operating mobility of the whole trailer is increased, and the labor efficiency is enhanced. The thermal insulation load workbench can keep the temperature for a hot steel billet, the temperature drop is reduced, the energy consumption with secondary heating is diminished, and the cost is lowered.
