Description

Technical Field

[0001] This utility model relates to the field of drone unloading technology, specifically a traction lifting drone cargo unloading system. Background Technology

[0002] With the promotion of the low-altitude economy in China, drone logistics is gradually becoming more widespread. However, the site conditions required for drone take-off and landing are not compatible with the urban built environment. Designated take-off and landing areas are often located in remote areas with insufficient logistics demand, while densely populated areas with high logistics demand cannot obtain effective drone logistics services. Traditional tricycle / electric vehicle transportation places a heavy burden on traffic. The traditional method of setting up helipads on building rooftops is inefficient, difficult to retrieve, and has many drawbacks because it cannot deliver directly to the destination and requires secondary transfers. Currently, there are also solutions that use logistics pipelines to vertically transport goods from rooftop helipads to corresponding floors. However, these solutions require significant alterations to the traditional building layout, are only suitable for new construction, cannot be modified on existing buildings, and are often costly, difficult to maintain, and thus difficult to promote.

This allows the multiple rotating columns to move into the spaces of multiple second rollers 8, so that the cargo 14 can be placed on the multiple second rollers 8. With the rotation of the multiple second rollers 8, the cargo 14 can enter the car storage 3 through the multiple second rollers 8.

[0035] Working principle and usage process of this utility model:

[0036] In use, the drone 19 carrying cargo 14 lands on the drone unloading landing platform 10. The elevator car 2 is driven by the traction machine 1 installed in the elevator shaft, which drives the elevator car 2 to the roof 6. The unloading port 11 opens. The cargo 14 of the drone 19 lands on multiple rotating columns. The unloading lifting platform 12 is activated, causing multiple vertical rods and multiple rotating columns to move downward, so that the cargo 14 lands on multiple second rollers 8. At this time, the air transport operation is completed, the unloading port 11 closes, and the drone 19 flies away.

[0037] The conveyor pipe door 9 and the car storage door 4 are opened, and multiple second rollers 8 drive the goods 14 through the conveyor pipe door 9 and the car storage door 4 into the car storage 3; then the conveyor pipe door 9 and the car storage door 4 are closed; the traction machine 1 drives the car 2 into the corresponding elevator hall 5; after the car 2 arrives at the corresponding elevator hall 5, the car storage door 4 on the car storage 3 is opened, and the goods 14, under the action of the electric push rod and push plate, pass through the rollers 18 and enter the conveyor belt 20; when the goods 14 arrive at the area of ​​the conveyor belt 20, the car storage door 4 is closed, and the conveying task of the car 2 is completed;

[0038] Goods 14 enter the conveyor belt 20 and are transported to the storage elevator 17 via the conveyor belt 20. The storage elevator 17 then moves the goods 14 horizontally to the storage cabinet 16 on the floor via the conveyor belt 20. The operator 15 can then retrieve the goods 14. The operator 15 can also use the elevator car 2 to reach other floors. The transport of goods 14 and the transport of operators 15 are independent and do not interfere with each other.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments.
