[0002] At present, the power supply drag chain of the stacking machine loading platform is generally installed parallel to the horizontal running direction (X axis) of the stacking machine. Due to the fast running speed of the stacking machine, the drag chain will swing greatly when the stacking machine starts and stops. When there are more wires in the drag chain and the self weight is larger, the swing is too large, which may cause the drag chain to break. The existing drag chain anti-swing assembly mostly adopts the way of adding counterweight to the drag chain. Although it can effectively prevent swing, adding counterweight to the drag chain increases the load bearing of the drag chain, which easily causes the drag chain to loosen and increases the risk of drag chain breakage.
