Description

Technical Field

[0001] This utility model relates to the field of stacker crane lifting technology, and specifically to a stacker crane lifting structure. Background Technology

[0002] High-speed stacker cranes are a key component of modern logistics and warehousing systems. They improve the efficiency, accuracy, and security of warehouses and help meet rapidly changing market demands. These automated devices have been widely used in many industries, including e-commerce, manufacturing, and food and beverage.

[0003] For example, Chinese patent application No. 202322727664.5 discloses a synchronous belt lifting device for a high-speed stacker, comprising: a base, a fixed plate mounted on the top of the base, and two sets of slide rails symmetrically mounted on the right edge of the fixed plate. This technical solution involves installing a motor on the top left side of the base, which drives a lead screw to rotate, thereby causing the lead sleeve on the lead screw to rise and fall along the lead screw, which in turn drives the first slide sleeves mounted on both sides of the lead sleeve to rise and fall, which in turn drives the L-plate mounted on the right side of the first slide sleeve to rise and fall, thereby causing the shelf mounted on the top of the L-plate to rise and fall. Items can be stacked on the top of the shelf. By raising and lowering the shelf, items can be stacked. The motor of this device is separated from the L-plate and the shelf, reducing the weight of the L-plate and the shelf, allowing heavier objects to be placed on the shelf, thereby increasing the stacking capacity of this device.

[0004] However, the following problems still exist in this technical solution: the storage space of the pallet is limited, and when the volume of goods is large, they need to be split and retrieved multiple times. When the amount of goods to be retrieved is large, the time required for retrieval will increase significantly, resulting in a decrease in the efficiency of the stacker crane in retrieving goods. Utility Model Content
