[0002] Automated stereoscopic warehouse is a new concept in logistics warehousing. The use of stereoscopic warehouse equipment can realize the rationalization of warehouse high-rise, automatic storage and retrieval, and simplified operation; automated stereoscopic warehouse is a form with a higher technical level at present. The main body of the automated stereoscopic warehouse is composed of shelves, aisle stacking cranes, inbound (outbound) warehouse workbenches, and automatic inbound (outbound) and operation control systems. The shelves are buildings or structures with steel or reinforced concrete structures. The shelves are standard-sized cargo spaces. The aisle stacking cranes travel through the aisles between the shelves to complete the storage and retrieval of goods. Computers and barcode technology are used in management. Four-way vehicles are used in the automated stereoscopic warehouses of the existing technology to carry out cargo handling operations.

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example: Figure 1-6 As shown, a four-way vehicle layer-changing forklift comprises a lift frame 1, a lift car 2 is installed in the lift frame 1, a fork is fixedly installed near the bottom surface of the lift frame 1, a lift drive 3 is fixedly installed on the top surface of the lift frame 1, the lift drive 3 is connected to the lift car 2, a blocker 6 is fixedly installed on the lift frame 1, a shuttle shelf 7 is fixedly installed on the side of the lift frame 1 near the fork, and a four-way vehicle 8 is arranged on the shuttle shelf 7, which can realize the layer-changing function of the four-way vehicle 8, thereby realizing the layer-changing operation of the four-way vehicle 8 on the goods on the shelf;

[0023] Among them, a lifting counterweight 4 is installed on the lifting drive 3, and the lifting counterweight 4 is installed on the hoist frame 1, which can improve the operation stability of the lifting drive 3;

[0024] Among them, a ladder is fixedly installed on the front side of the hoist frame 1, and a ladder guard net 5 is fixedly installed on the ladder, which can serve as a device to protect the safety of maintenance personnel during maintenance, and is also a safety barrier when the equipment needs maintenance;

[0025] Several mounting plates are fixedly installed on the left and right sides of the elevator frame 1, and two blockers 6 are symmetrically fixedly installed on each mounting plate. There are five mounting plates evenly distributed on the left and right sides of the elevator frame 1, which are used to prevent the trolley from falling when the car has not reached the specified floor.

[0026] Working principle: When the device of the utility model is performing the cargo layer changing operation, when the cargo on the shelf reaches the designated layer and needs to apply for layer changing or out of the warehouse, the computer system sends a command to the forklift to let the lifting car 2 of the lifting machine reach the corresponding layer, and the electric control system controls the related actions of the lifting car 2 to complete the corresponding actions. First, when the lifting car 2 reaches the designated layer, the control system self-judges whether it has reached the corresponding layer. After confirming that it has reached the designated layer, it prepares to execute the next action instruction. Secondly, the photoelectric sensor on the lifting car 2 detects whether there is cargo stored on the shuttle shelf 7. At the same time, another group of photoelectric sensors detects whether the four-way car 8 exists at the lower end of the cargo. When the four-way vehicle 8 is at the lower end of the goods, the goods cannot be forked. Only when the four-way vehicle 8 is not at the lower end of the goods can the goods be forked, otherwise the fork will damage the four-way vehicle 8. Again, after the detection is correct, the fork on the lifting car 2 starts to execute the action, forks the goods and places them on the fork. After the forking is completed, the over-limit sensor on the lifting car 2 determines whether the goods exceed the two ends of the lifting car 2 and determines that the goods have been forked into the lifting car 2. After the detection is correct, the control system can perform the next action instruction. Finally, the lifting drive 3 starts to run, and the goods on the lifting car 2 are transported to the specified layer. The fork on the lifting car 2 puts the goods on the specified layer or out of the warehouse, completing the layer change of the goods.

[0027] When the four-way vehicle 8 changes floors: when the four-way vehicle 8 on the shelf reaches the designated floor and needs to apply for a change of floors, the computer system sends a command to the forklift to let the lifting car 2 of the lifting machine reach the corresponding floor, and the electric control system controls the relevant actions of the lifting car 2 to complete the corresponding actions; first, when the lifting car reaches the designated floor, the control system self-judges whether it has reached the corresponding floor, and after confirming that it has reached the designated floor, it prepares to execute the next action instruction; secondly, the blocking mechanism on the lifting car 2 executes the action, opens the left and right blockers 6 on the lifting frame 1, and the photoelectric sensor on the lifting car 2 detects and determines whether the four-way vehicle 8 on the shelf has changed floors. Whether the four-way car 8 is on the shuttle shelf 7; again, after the detection is correct, the four-way car 8 on the shuttle shelf 7 starts to execute the action and starts to move towards the lifting car 2. After moving to the lifting car 2, the photoelectric sensor on the lifting car 2 determines whether the four-way car 8 is in the lifting car 2, and at the same time, the over-limit sensor determines whether the four-way car 8 exceeds the two ends of the lifting car 2. After the detection is correct, the control system can execute the next action instruction; finally, the lifting drive 3 starts to run, and the four-way car 8 on the lifting car 2 is transported to the designated layer, and the four-way car 8 on the lifting car 2 drives into the corresponding designated layer to complete the layer change of the four-way car 8.
