After the two groups of clamping plates 316 clamp the beam, the inclined plate 48 moves to the left to assist the beam to move upward, and then the No. 3 cylinder 51 is started, and then the No. 3 cylinder 51 drives the No. 2 rack 52 to move, and the No. 2 rack 52 slides on the top of the moving platform 1, and then drives the No. 4 gear 53 to rotate, and the No. 4 gear 53 drives the bending rod 54 to rotate, and then the bending rod 54 drives the supporting plate 55 to rotate to the beam.

When the inclined plate 48 moves to the left, due to the inclination of the top surface of the inclined plate 48, it gradually contacts the recessed part of the beam when moving to the left. After clamping the beam, the No. 1 cylinder 39 contracts and cooperates with the inclined plate 48 to drive the beam to move upward, and then the rotating cylinder 32 is started, and the rotating The rotating cylinder 32 electrically rotates the rotating rod 33, and then the rotating rod 33 drives the fixed plate 34 to rotate, so the fixed plate 34 drives the No. 1 cylinder 39 to rotate, and the No. 1 cylinder 39 drives the protective shell 310 to rotate to the top of another set of conveyor belts, and the rotating rod 33 drives the large pulley 35 to rotate, and further, the large pulley 35 drives the belt 37 to rotate, and then the belt 37 drives the small pulley 36 to rotate, and then the small pulley 36 drives the No. 1 cylinder 39 to rotate. Since the diameter of the large pulley 35 is twice the diameter of the small pulley 36, the rotating cylinder 32 rotates 90 degrees, the small pulley 36 rotates 180 degrees, and then the small pulley 36 rotates 90 degrees relative to the rotating cylinder 32, and then when the two sets of clamping plates 316 grab the beam and rotate it to another set of conveyor belts, it is still ensured that the same side of the beam is in line with the conveyor belt for convenient transportation;
