[0002] Automated high-bay warehouses (AHWs) are a new concept in logistics and warehousing. Using AHW equipment, they streamline warehouse levels, automate storage and retrieval, and simplify operations. AHWs represent a state-of-the-art technology. The main components of an AHW are racks, aisle-mounted stacking cranes, access platforms, automated loading and unloading systems, and an operational control system.

[0028] The present invention will be further described below in conjunction with the accompanying drawings:

[0029] like Figure 1 — Figure 5 As shown, this embodiment provides an energy-saving automated three-dimensional warehouse, including several shelves, a shuttle car 2, a running rail 3, a ceiling rail frame 4 and a stacking system 5. The ceiling rail frame 4 is installed between the tops of two adjacent shelves. The shelves are conventional shelves in this field and will not be described in detail here. The number of layers and height can be set as needed. The shelves are not shown in the figure. The running rail 3 extends between two adjacent shelves. The upper and lower ends of the shuttle car 2 slide along the ceiling rail frame 4 and the running rail 3 respectively, so that the shuttle car 2 can run between the running rail 3 and the ceiling rail frame 4. The stacking system 5 extends to the side of the running rail 3. The stacking system 5 is used to stack the goods, and then the forklift places the stack stacked by the stacking system 5 on the shuttle car 2.

The shuttle frame 21 slides along the overhead rail frame 4 and the running rail 3. 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 rise and fall, 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 stack lifted into place into the specified position of the shelf. The energy storage tank 23 is installed on the shuttle frame 21, and the lifting system 22 can be lifted and lowered. It is installed on the shuttle rack 21, the auxiliary lifting device 25 is connected to the lifting system 22 in transmission, and the pressurizing devices 24 are vertically distributed and installed on the shuttle rack 21. When the lifting system 22 descends along the shuttle rack 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 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. This design can utilize the potential energy released when the high-altitude stacking is transported downward, thereby achieving energy saving, safety and reliability.

[0031] Specifically, the ceiling rail frame 4 includes a ceiling rail bracket 41 and a top guide rail 42. The ceiling rail bracket 41 is placed between the tops of two adjacent shelves, and the top guide rail 42 is installed at the bottom of the ceiling rail bracket 41.

The palletizing robot 53 is installed on the sides of the pallet conveyor 51 and the box conveyor 52. The palletizing robot 53 stacks the materials on the box conveyor 52 on the transfer pallet transported by the pallet conveyor 51. The pallet conveyor 51 transports the stacked goods to the vicinity of the shuttle car 2, and the stack is then placed on the shuttle car 2 by a forklift.

[0033] Specifically, the shuttle frame 21 is rotatably provided with a plurality of running wheels 211 that roll along the moving rail at the bottom, and the shuttle frame 21 is rotatably provided with a plurality of guide wheels 212 that roll along the ceiling rail frame 4 at the top.

The extrusion plate 6 has a horizontal extrusion section 61, and a support section 62 extending vertically upward is provided on the upper side of the extrusion section 61. When the lifting frame 221 moves downward, the extrusion plate 6 is squeezed onto the lifting pressure cylinder 241 for pressurization. At this time, the support section 62 presses on the lifting frame 221. When the lifting frame 221 moves upward, the extrusion plate 6 is pressed onto the lifting pressure cylinder 241 and then rotates, thereby avoiding the lifting pressure cylinder 241. An extrusion return spring 63 is provided between the support section 62 and the lifting frame 221. After the extrusion plate 6 is separated from the lifting pressure cylinder 241, the extrusion return spring 63 drives the support section 62 and the extrusion section 61 to reset.

[0039] Specifically, the auxiliary lifting device 25 includes an auxiliary lifting cylinder, which is transmission-connected to the lifting device. The auxiliary lifting cylinder is connected to the energy storage tank 23 through a solenoid valve to perform auxiliary lifting to achieve energy saving.
