Description

Technical Field

[0001] The utility model belongs to the technical field of warehouse stacking equipment, and in particular relates to a rotating device of a stacking crane and a stacking crane with the rotating device. Background Art

[0002] At present, the storage cost is getting higher and higher. In order to make full use of storage space and reduce storage costs, the stacking height of goods in warehouses is getting higher and higher, and the application of three-dimensional warehouses is increasing. Three-dimensional warehouses generally refer to the use of several layers, dozens of layers or even dozens of layers of shelves to store unit goods. Due to the high height of three-dimensional warehouses, the corresponding handling and warehousing and warehousing operations must rely on handling equipment.

[0003] At present, the handling equipment used for cargo handling and stacking in warehouses mainly includes forklifts, aisle stackers and stacking cranes. The stacking height of forklifts is generally within 3 meters, which limits the height of cargo stacking and wastes the storage space of warehouses. Moreover, the turning radius of forklifts is large, and sufficient operating space needs to be left between the shelves of warehouses for forklifts, which also wastes the storage space of warehouses. Aisle stackers can only move along the tracks laid in the aisles between the shelves. Not only does it have a large moving stroke and a lot of useless work, it increases energy consumption and is prone to collision. The stacking crane is a lifting track suspended at the lower end of the mobile trolley of the warehouse crane. A load platform equipped with a fork that can move up and down along the lifting track is set on the lifting track. The fork and the load platform are used to realize the movement of goods at the height of the warehouse, and the crane and the mobile trolley are used to realize the movement of goods in the width and length directions of the warehouse, thereby realizing the stacking of goods. For example, the Chinese utility model patent with the patent number "ZL2019217063580" and the name "A stacking crane for a three-dimensional warehouse" discloses a stacking crane that can lift goods and move along the aisles between shelves driven by the crane. However, the stacking crane does not have a rotation function. Therefore, the stacking crane adopts a bidirectional fork. Although it can unload goods on one side and load goods on the other side at the same time, which improves the loading and unloading efficiency, its flexibility is poor. Loading and unloading goods can only be done in the extension direction of the fork, and loading and unloading goods in multiple directions cannot be achieved. If the opening direction of the storage compartment of the shelf is perpendicular or inclined to the extension direction of the fork, the stacking crane cannot load and unload goods, which limits the placement direction of the shelves in the warehouse, and also limits the placement direction of the goods on the ground.
