Stacking cranes, also known as stacking machines, are lifting and transportation equipment in three-dimensional warehouses.
[0003] However, the three-dimensional warehouse stacker currently used has the following defects:
[0004] First, when the stacker in the three-dimensional warehouse takes and places goods, it is necessary to align the pallet of the stacker with the cargo grid of the three-dimensional warehouse first. At present, since the stacker in the three-dimensional warehouse is not equipped with a positioning structure, the pallet of the stacker is generally aligned with the cargo grid of the three-dimensional warehouse by manual control. However, this alignment method cannot accurately align the pallet with the cargo grid, which makes it inconvenient for the stacker to take and place goods; second, when the pallet of the existing three-dimensional warehouse stacker takes and places goods, the goods are not clamped and fixed. When the stacker takes and places goods, the goods may fall from the pallet and cause damage to the goods.
[0005] Based on this, we provide a three-dimensional warehouse stacker with a positioning structure. Utility Model Content
