Technical Field
[0001] This utility model relates to the field of stacker crane technology, specifically a multi-storage stacker crane. Background Technology
[0002] Against the backdrop of rapid development in the global logistics industry, efficient and intelligent warehousing equipment has become key to improving warehouse operational efficiency and reducing operating costs. Stacker cranes are the hallmark of automated storage and retrieval systems (AS / RS). Their function is to coordinate a series of actions within the aisles, including horizontal reciprocating linear movement, vertical lifting, and fork extension and retraction, to realize the inbound operation of goods from the aisle end conveyor to the designated storage location, or the outbound operation from the designated storage location to the aisle end conveyor, thus achieving automated inbound and outbound operations together with the aisle end inbound / outbound conveyor system. The emergence of stacker cranes has greatly improved the area and space utilization of warehouses, thus making them a core piece of equipment in automated warehouses. Currently, after decades of development, facing the demand for increased warehouse space utilization, multi-storage-position stacker cranes with stronger storage capacity and higher efficiency have received widespread attention globally. As the core equipment of current AS / RS, multi-storage-position stacker cranes, with their advantages of high space utilization and high degree of automation, are widely used in industries such as food, pharmaceuticals, e-commerce, and automotive parts.
[0003] Most of the stacker cranes on the market currently adopt a single storage location design, which means that only one storage location can be accessed in a single operation. Each single storage location stacker crane needs to complete the entire process of positioning, picking up and resetting for each storage and retrieval, which reduces the overall operation efficiency.
[0004] Therefore, multi-storage stacker cranes are needed to improve upon the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a multi-storage-position stacker to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A multi-storage stacker crane includes a column, a traveling base connected to the lower end of the column, a traveling limit structure connected to the upper end of the column, a drive structure disposed on the side of the column, a connecting structure docking with the drive structure, a positioning wheel assembly disposed on the side of the traveling limit structure, and a storage assembly disposed through the positioning wheel assembly by the connecting structure. The storage assembly includes several storage units arranged vertically along the column, each of the storage units being slidably connected to the side of the column, and adjacent storage units being connected by a plug-in structure. Each storage unit has an adjusting component connected to the upper ends of both sides, the output end of which docks with the upper storage unit to adjust the spacing between adjacent storage units.
[0008] As a preferred embodiment of this utility model, the storage unit includes a support plate, with limiting members fixedly connected to both sides of the support plate, the plug-in structure connected to the inner side of the limiting members on both sides, and a baffle fixedly connected between the limiting members on both sides.

[0010] As a preferred embodiment of this utility model, the two sides of the column are fixedly connected with limiting protrusions, and the side of the limiting member is provided with a groove that cooperates with the limiting protrusions for limiting and sliding connection.
[0011] The bottom end of the limiting member is connected to limiting roller a and limiting roller b respectively, and the limiting roller a and limiting roller b respectively cooperate with the two sides of the column to slide and abut.
[0012] As a preferred embodiment of this utility model, the adjusting component is a hydraulic cylinder, which is fixedly connected to the upper end of the limiting component.
[0013] As a preferred embodiment of this utility model, the drive structure includes a reducer installed on one side of the column, the input end of the reducer is connected to a drive motor, and the output end of the reducer is connected to the connecting structure.

[0032] The walking base includes a base 3 that is fixedly connected to the lower end of the column 1. The two ends of the base 3 are respectively connected to a movable part a4 and a movable part b5, and support feet 6 are installed on the sides of both the movable part a4 and the movable part b5.
[0033] The stacker crane uses column 1 as its core support structure. Its lower end is connected to the traveling base, which includes base 3, moving part a4, moving part b5, and support foot 6. Its upper end is connected to the traveling limit structure. In the traveling base, moving part a4 and moving part b5 are connected to the drive unit to drive the stacker crane to move horizontally along the aisle. The support foot 6 provides additional support when the equipment is stationary to ensure overall stability.

[0035] Please refer to Figure 1 , 2 3 and 4, the plug-in structure includes a connecting rod 13, and the inner side of the connecting rod 13 is connected to a plug-in part, the plug-in part is provided with a slot 14, the bottom of the connecting rod 13 is fixedly connected to a plug-in rod, and the plug-in rod and the slot 14 are engaged and plugged in.
[0036] The two sides of the column 1 are fixedly connected to the limiting protrusions 26. The side of the limiting member 7 is provided with a groove that cooperates with the limiting protrusions 26 for limiting and sliding connection. The bottom end of the limiting member 7 is respectively connected to the limiting roller a17 and the limiting roller b18. The limiting roller a17 and the limiting roller b18 respectively cooperate with the two sides of the column 1 for sliding contact.
[0037] The adjusting component uses a hydraulic cylinder 10, which is fixedly connected to the upper end of the limiting component 7.
[0038] The storage assembly consists of multiple storage units arranged vertically along the column 1. Each storage unit includes a support plate 12, two limiting members 7 on both sides and a baffle 11 in the middle. The support plate 12 is used to support the goods, the baffle 11 prevents the goods from slipping, and the limiting members 7 achieve precise lifting and lowering through the following structure.
[0039] The side of the limiting component 7 has a groove that matches the limiting protrusions 26 on both sides of the column 1. The lateral displacement of the storage unit is constrained by the sliding engagement between the groove and the limiting protrusions 26.
[0040] The lower end of the limiting component 7 is provided with limiting rollers a17 and b18, which slide against the two sides of the column 1 respectively. The rolling friction reduces the lifting resistance and further limits the shaking of the storage unit.

The pressing wheel 21 is slidably connected to the column 1 through a sliding member. A spring 20 is provided between the connecting seat 19 and the pressing wheel 21.
[0044] The column 1 is equipped with a drive structure and a connection structure. The drive motor 8 provides power, which is reduced and increased in torque by the reducer 9 to drive the roller shaft 24 to rotate, winding or releasing the connecting rope 25. The connecting rope 25 passes through the positioning wheel assembly on the side of the walking limit structure and is connected to the storage unit at the bottom. The overall lifting and lowering of the storage unit is controlled by the winding and unwinding of the connecting rope 25.
[0045] In the positioning wheel assembly, the tensioning component pushes the abutment wheel 21 against the connecting rope 25 through the elastic force of the spring 20, ensuring that the connecting rope 25 is always taut and avoiding lifting jamming or positioning deviation caused by rope slack.
