[0049] The usage method and working principle of this device: First, the movable cover 51 on the carriage cover 5 is opened to put the goods inside the semi-trailer carriage 4. When the semi-trailer moves to the designated position, the first hydraulic push rod 33 on the turning assembly 3 expands and contracts. The first hydraulic push rod 33 rotates a certain angle on the first fixed seat 32 and the second fixed seat 34. The second fixed seat 34 applies pressure to the fixed blocks 67, and the two fixed blocks 67 rotate around the rotating shaft 68. At the same time, the inner plate 66 expands and contracts inside the turning plate 64, and the turning plates 64 on both sides rotate on the second rotating body 63. The turning plate 64 drives the clamping block 65 away from the movable plate 62, and the movable plates 62 on both sides of the semi-trailer carriage 4 are opened. Then, through the rotation of the movable plate 62 on the first rotating body 61, and the guide plate inside the semi-trailer chassis 1 is moved out to guide the goods and prevent the goods from falling on the semi-trailer wheels. The goods are discharged from the front and rear sides of the semi-trailer carriage 4. At the same time, the inner plate 66 and the fixed blocks 67 apply pressure to the movable body 8, and the movable body 8 moves on the guide body 7. Through the protection of the gap between the inner plates 66 by the movable body 8, the goods are prevented from falling. Then, by turning the turning plates 64 inside the semi-trailer carriage 4 at different positions, the goods at different sections are unloaded, realizing automatic two-side unloading of the semi-trailer, avoiding the material falling from the middle of the two-side unloading, preventing the towing rope from damaging the goods, and unloading the semi-trailer in sections.
