[0013] The utility model is described in detail below with reference to the accompanying drawings:

[0014] A drag chain anti-swing mechanism is provided on a stacker, comprising a lower crossbeam 1, an upper crossbeam 5, a left column 2 and a right column 3, which form a walking frame of the stacker, a liftable cargo platform 4 is provided between the left column 2 and the right column 3, a cargo platform left hanger 6 and a cargo platform right hanger 7 are provided on the cargo platform 4, and the cargo is transferred through the cargo platform 4, a drag chain fixed end crossbeam 8 is provided in the middle of the left column 2, and a fixed end of a drag chain 16 is connected to the fixed end crossbeam 8 of the drag chain 9. A drag chain moving end fixing seat 14 is provided on the left hanger 6 of the cargo platform, and a moving end 15 of a drag chain 16 is connected to the drag chain moving end fixing seat 14. The entire drag chain 16 is in a dynamic U-shape. When the cargo platform 4 is raised, the U-shaped drag chain 16 presents a U-shape with a long right side and a short left side. When the cargo platform 4 is lowered, the U-shaped drag chain 16 presents a U-shape with a short right side and a long left side. A drag chain guide U-shaped channel steel is provided on the left column 2 below the fixed end cross beam 8 of the drag chain 10, the drag chain 16 below the fixed end 9 is movably embedded in the drag chain guide U-shaped channel steel 10 to prevent the drag chain 16 from swinging back and forth; a left front angle steel column 12 is arranged on the front side of the left end of the cargo platform 4, the lower end of the left front angle steel column 12 is fixedly connected to the top surface of the lower cross beam 1, the upper end of the left front angle steel column 12 is fixedly connected to the bottom surface of the upper cross beam 5, and a left rear angle steel column 13 is arranged on the rear side of the left end of the cargo platform 4, the lower end of the left rear angle steel column 13 is fixedly connected to the lower cross beam 5.
