Description

Technical Field

[0001] The present invention relates to the technical field of warehouses, and in particular to an energy-saving automated stereoscopic warehouse. Background Art

[0002] An automated stereoscopic warehouse is a new concept in logistics warehousing. Using stereoscopic warehouse equipment can achieve the rationalization of high-rise warehouses, automated access, and simple operation; an automated stereoscopic warehouse is a form with a relatively high current technical level. The main body of an automated stereoscopic warehouse consists of shelves, aisle stacker cranes, inbound and outbound workbenches, an automatic in-and-out system, and an operation control system. The shelves are buildings or structures made of steel or reinforced concrete. Inside the shelves are standard-sized storage spaces. The aisle stacker crane, also known as a shuttle car, travels through the aisles between the shelves to complete the work of storing and retrieving goods. Computer and barcode technologies are used in management.

[0003] The existing aisle stacker cranes used in stereoscopic warehouses consume a large amount of energy because they need to frequently lift or lower goods, and their anti-drop function is not perfect. Summary of the Invention

The pressurizing device 24 and the auxiliary lifting device 25 are respectively connected to the energy storage tank 23. The lifting system 22 is used to drive the goods to be lifted and lowered, and is driven by the shuttle frame 21 to approach the shelf. A commercially available translation clamping device is installed on the lifting system 22. The translation clamping device adopts a conventional guide rail slider transverse movement mechanism, which will not be repeated here. The translation clamping device is used to translate the lifted stack into the specified position of the shelf.

The auxiliary lifting device 25 is installed on the shuttle frame 21, and the auxiliary lifting device 25 is connected to the lifting system 22 in transmission. The pressurizing devices 24 are vertically distributed and installed on the shuttle frame 21. When the lifting system 22 descends along the shuttle frame 21, it drives the pressurizing device 24 to move and then pressurizes the energy storage tank 23, thereby realizing the energy storage of the energy storage tank 23. On the other hand, each pressurizing device 24 provides a deceleration effect for the descent of the lifting system 22, thereby improving the safety. When the lifting system 22 rises, the energy storage tank 23 drives the auxiliary lifting device 25 to move and then assists in driving the lifting system 22 to rise. Such a design can utilize the potential energy released when the high stack is transported downward, thereby achieving energy saving, safety and reliability.
