Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of port logistics equipment, in particular to a straight-in and straight-out type commercial vehicle stereoscopic yard device and its operation method, and additionally relates to a commercial vehicle planar circulating stereoscopic warehouse and its operation method. BACKGROUND

[0002] At present, the domestic automobile roll-on / roll-off wharf mainly includes Shanghai Port, Tianjin Port, Guangzhou Port, Ningbo Port, Dalian Port, Yantai Port and Lianyungang Port, which complete more than 95% of the automobile import and export throughput in China. The roll-on / roll-off wharf of commercial vehicles in major ports around the world basically follows the ground plane yard port collection and port distribution operation mode. This traditional mode not only needs to occupy a large amount of land, but also affects the operation efficiency of loading and unloading ships, and further affects the operating costs of wharf companies and ship companies. In the past five years, China's automobile exports, especially new energy automobile exports, have increased by more than 40% on average each year. In 2022, automobile exports reached 3.4 million vehicles, an increase of 51% over the same period. From January to July 2023, automobile exports reached 2.533 million vehicles, an increase of 67.9% over the same period, making China the largest automobile exporter. In the face of the compound growth of domestic vehicle production and export proportion, automobile exports will still have a large demand space for the automobile yard capacity of roll-on / roll-off wharfs.

[0003] In order to solve the problem of serious shortage of commercial vehicle yard capacity caused by rapid growth of commercial vehicle throughput in roll-on / roll-off wharfs, some ports have begun to build whole vehicle automatic stereoscopic warehouses. For example, the intelligent stereoscopic vehicle warehouse project of Lianyungang Port, which plans to occupy an area of 30,200 square meters, builds an intelligent stereoscopic vehicle warehouse with a total area of 74,000 square meters, a total of 5 layers and about 5,200 parking spaces, all of which use AGV robots for automatic parking. For example, the full-automatic shelf type commercial vehicle transfer warehouse project of Shanghai Port uses 8 rail-mounted tunnel stackers, 8 layers of stereoscopic shelves, and can stack 6,160 vehicles. For example, the self-propelled stereoscopic parking lot, the parking building of Tianjin Port has 5 layers and an area of 106,000 square meters, which can park 3,400 vehicles. The parking building of Ningbo Port has 5 layers and an area of 40,000 square meters, which can park 1,674 vehicles.

[0004] From the above form of automobile roll-on roll-off wharf automobile yard, there are mainly three kinds: the first is to occupy a large amount of land to build a flat automobile yard, the second is to build a self-propelled (including AGV, relying on the elevator to move up and down AGV) three-dimensional parking lot, and the third is to build a roadway type shelf three-dimensional warehouse. The first kind of automobile yard at the expense of land obviously cannot continue; the second kind of self-propelled (including AGV) three-dimensional parking lot has high construction cost, low space utilization rate, low efficiency of loading and unloading, and high operating cost; the third kind of roadway type shelf three-dimensional warehouse has high construction cost, low space utilization rate, and low efficiency of loading and unloading. Especially, the designers of the second and third kinds do not design according to the characteristics of the roll-on roll-off wharf commercial automobile yard, but simply apply the technical scheme of the city three-dimensional parking lot and the three-dimensional warehouse technical scheme to the roll-on roll-off wharf commercial automobile yard, which is the fundamental problem causing large investment, low efficiency and high operating cost.

[0005] The characteristics of the roll-on roll-off wharf automobile yard are the temporary parking of automobiles during the collection and distribution of automobiles. The collection is the storage of commercial automobiles in the automobile yard of the roll-on roll-off wharf before loading, and the collection of commercial automobiles generally involves 2 to 3 automobile manufacturers radiated by the port, and more than a dozen automobile manufacturers, and the number of commercial automobiles collected by each batch of these manufacturers is large, with a few hundred vehicles and a few thousand vehicles, and a brand. The distribution is the storage of commercial automobiles in the automobile yard of the roll-on roll-off wharf after unloading, and the distribution of commercial automobiles is aimed at the automobile 4S store consumer market of the cities radiated by the port, and the consumers are personalized, which causes the problem of multiple brands and models and small batch of distribution commercial automobiles, with a few vehicles and dozens of vehicles imported by each 4S store. Generally, the number of collected commercial automobiles of the roll-on roll-off wharf is much larger than the number of distributed commercial automobiles. When the collected commercial automobiles are loaded, only one vehicle at a time needs to be sequentially driven into the cabin from the commercial automobile yard; and when the distributed commercial automobiles are distributed, the 4S store that randomly comes to pick up the vehicle "picks the vehicle" from the commercial automobile yard and leaves.

[0006] In view of this, the applicant provides a roll-on roll-off wharf automobile three-dimensional yard device and a commercial automobile and container integrated three-dimensional yard device, with the publication number CN116216343A, which can basically meet the characteristics of high efficiency, high density and low investment of collection and distribution. Therefore, in the subsequent research and development process, a technical scheme for greatly improving the access efficiency of collected commercial automobiles is designed.

[0007] In addition, the current passenger car manufacturing enterprises also have similar problems in the production process of the body three-dimensional storage and finished automobile storage. In the production process, the semi-finished car bodies are stored in the form of a roadway three-dimensional warehouse in the automobile assembly workshop to save the area of the assembly workshop. In a continuous production process, the disadvantages of the roadway three-dimensional warehouse are that the entire assembly line of the assembly workshop will stop once a fault occurs, and there are problems of low space utilization and high investment cost. The finished automobile storage of the automobile manufacturing enterprise is generally carried out by using the factory site or renting a site near the factory site, which brings additional rental site cost, transportation cost and guarding cost to the enterprise.

Each storage conveyor line 3 is composed of several conveying power units 4, and the conveying power units 4 at both ends are set as longitudinal and transverse reversing conveying power units 41. A grid-shaped vehicle platform 61 is arranged on each conveying power unit 4 (including longitudinal and transverse reversing conveying power units 41). The front end and / or rear end of the conveying direction of the storage conveyor line 3 are provided with the entrance and exit 2 of the flat-panel circulating automated warehouse 8 for automobiles. A double-layer lifting mechanism 5 is provided at the entrance and exit 2 of the flat-panel circulating automated warehouse 8 for automobiles. The upper lifting plate 51 and the lower lifting plate 52 of the lifting mechanism 5 are provided with the conveying power units 4. An automobile operation and exchange platform 7 is arranged outside the lifting mechanism 5. A set of conveying power units 4 is arranged on the automobile operation and exchange platform 7.

[0065] In this system, each car storage layer 11 has one or more adjacent storage conveyor lines 3 forming a conveyor unit. Since the storage conveyor lines 3 are changed to longitudinal and transverse reversing conveyor power units 41 at both ends, the entrances and exits of the commercial vehicle flat circulation three-dimensional warehouse 8 can be reduced to one entrance 21 and one exit 22. One entrance and exit 2 corresponds to one conveyor unit.
