Description

Technical Field

[0001] The present invention relates to the field of container terminal stacking, and in particular to a container storage and retrieval system, storage and retrieval method, and a stacking yard. Background Art

[0002] A container yard is a place dedicated to collecting, keeping, stacking or handing over containers. It is a transition area specially set up for the connection between container loading and unloading and transshipment. Its main function is to serve the storage, safekeeping, and distribution of containers. The container yard loads and unloads containers through loading and unloading equipment such as container cranes, and carries out container loading and unloading through horizontal transport vehicles.

[0003] The current container yard loading and unloading process has the advantages of centralized storage and convenient management, but the inventors have found that the current container yard loading and unloading process also has disadvantages. Since the areas used for storing containers are mostly flat sites, the containers are generally stacked layer by layer. Affected by factors such as wind resistance, vibration, and the offset of the center of gravity after stacking, the containers are unstable and sway after being stacked. For safety reasons, conventional yards generally have a maximum stacking height of 3 to 6 layers for loaded containers and 7 to 8 layers for empty containers. The larger the yard capacity, the more land resources are required. In addition, due to the limitations of the characteristics of the stacking containers, container handling often requires sorting of containers, and the container turnover rate also increases significantly with the increase in the number of layers.

[0004] As the scale of port operations expands, the contradiction between port land use restrictions becomes increasingly prominent, and the pressure on container storage and access in the yard becomes more apparent. How to achieve more storage volume in a limited area and reduce the turnover rate is bound to be on the agenda of port operators. Summary of the Invention

[0005] The object of the present invention is to provide a container storage and retrieval system, which can realize a larger storage volume in a limited area and reduce the container turnover rate.

[0006] To achieve the above-mentioned purpose, the container storage and retrieval system includes:

[0019] Wherein, a plurality of the horizontal rod extension sections, the plurality of the interactive frame longitudinal rods and the plurality of the interactive frame vertical rods enclose a plurality of cubic spaces in the same interactive layer, wherein the interior or top of one of the cubic spaces defines the interactive position;

[0020] Wherein, in two adjacent interaction layers, the interaction positions are staggered along the extension direction of the horizontal rod extension section and along the extension direction of the interaction frame longitudinal rod.

[0021] In one or more embodiments, the second track is disposed on the crossbar and the crossbar extension.

[0022] In one or more embodiments, from the top surface of the interaction rack downward, the interaction layers of the N+1 to 2N layers are spaced one cubic space away from the storage rack relative to the interaction layers of the 1 to N layers; the interaction layers of the 2N+1 to 3N layers are spaced one cubic space away from the storage rack relative to the interaction layers of the N+1 to 2N layers;

[0023] Wherein, N is the number of the cubic spaces along the extension direction of the longitudinal rod of the interactive frame.

[0034] f. The second transport device uses its own lifting assembly to lift the container and ensure that the bottom of the container is higher than the upper surface of the container shelf in the container cargo space;

[0035] g. The second transport device, carrying the container, moves away from the first transport device along the third track of the first transport device and enters the designated storage location along the first track at the container cargo area. Once in position, the second transport device's built-in lifting assembly lowers the container so that the bottom of the container is securely placed on the container shelf.

[0036] h. After the lifting assembly is separated from the bottom surface of the container, the second transport device moves away from the designated storage position and enters the upper surface of the first transport device, and the container storage operation process is completed.

[0050] The following embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0052] In order to solve the pressure problem in existing container yards, the applicant has found that the above-mentioned problem can be solved by proposing a container storage and retrieval system for yard loading and unloading that can store more containers in a limited area.

[0053] On the one hand, according to some embodiments of the present application, a container access system is provided, such as Figure 1 shows a front schematic diagram of a container access system according to some embodiments of the present application, Figure 2 For Figure 1 The top view of the container storage and retrieval system as seen from the middle C direction, Figure 3 for Figure 1 Cross-section view in the AA direction, Figure 4 for Figure 1 Cross-section view along the middle BB direction.

[0054] The container storage and retrieval system includes a storage rack 1 and an interactive rack 2. The container storage and retrieval system has a height direction h, a length direction a and a width direction b. The height direction h, the length direction a and the width direction b are respectively Figures 1 to 4 Marked in.

[0055] The storage rack 1 includes multiple storage layers 10. It is understood that each storage layer 10 is a layer parallel to the horizontal plane. Multiple storage layers 10 are stacked along the height direction h to form the storage rack 1. Each storage layer 10 has multiple storage positions 100, and each storage position 100 provides space for storing containers. Figure 2 What is seen is one of the storage layers 10 , ie the top layer of the storage rack 1 .

[0056] The interactive rack 2 includes multiple interactive layers 20, each of which is a layer parallel to the horizontal plane. Multiple interactive layers 20 are stacked along the height direction h to form a storage rack 1. Each interactive layer 20 is arranged corresponding to the storage layer 10, that is, each interactive layer 20 has a storage layer 10 arranged at the same level as it in the height direction h, so that the interactive layer 20 at the same height is connected to the internal space of the storage layer 10. Among them, each interactive layer 20 is provided with at least one interactive position 200, such as Figure 3 In the embodiment shown in , the number of interaction positions 200 provided in each interaction layer 20 is one, and at the same time, Figure 2 As shown, in the orthographic projection viewed from a top-down angle along the container access system, the top of each interaction position 200 is open, and at the same time, multiple interaction positions 200 are staggered with each other, that is, the multiple interaction positions 200 in the orthographic projection viewed from a top-down angle do not overlap with each other, so that the container can be lifted from above the interaction rack 2 to the interaction position 200.

[0057] like Figure 4 As shown, a first track 11 is also arranged in each storage layer 10, and the first track 11 is arranged to any storage position 100 in each storage layer 10, that is, at least one first track 11 is arranged around any storage position 100, so that the storage position 100 at any position of the layer can be reached through the first track 11.

[0058] like Figure 1 as well as Figure 4 As shown, a second track 12 is further provided in each storage layer 10 and the interaction layer 20 . The second track 12 extends from the storage layer 20 to the storage layer 10 , so that the storage layer 10 and the interaction layer 20 at the same height are connected through the second track 12 .

[0059] The container access system also includes a transport unit 3, such as Figure 5A schematic diagram of a transport unit according to some embodiments of the present application is shown. As shown, the transport unit 3 is disposed in the exchange position 20 and includes a first transport device 31 and a second transport device 32. The first transport device 31 is disposed on the second track 12 and is movable along the second track 12. A third track 33 is disposed above the first transport device 31. The second transport device 32 is disposed on the third track 33 and is movable along the third track 33. A load-bearing portion 320 is disposed above the second transport device 320, which can accommodate a container. When the first transport device 31 moves along the second track 12, it can be transported from the exchange position 200 to the storage position 100 along the second track 12. When in the storage position 100, the third track 33 and the first track 11 are at the same level and are connected. This allows the second transport device 32 to move from the third track 33 to the first track 11 and then along the first track 11 to any storage position 100 in the storage layer 10, thereby transporting the container from the exchange rack 2 to any storage position on the storage rack 1.

[0060] In the description of the embodiments of the present application, the technical terms "first" and "second", such as "first track" and "second track", are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features.

[0061] In the description of the embodiments of the present application, “multiple” means more than two, unless otherwise clearly and specifically defined.

[0062] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0063] Please continue to see Figures 1 to 4According to some embodiments of the present application, a storage rack 1 is composed of multiple horizontal bars 101, multiple vertical bars 102, and multiple vertical bars 103. Each horizontal bar 101 extends along a length direction a, multiple vertical bars 102 extend along a width direction b, and multiple vertical bars 103 extend along a height direction h. It is understood that the "bar" referred to herein refers to a slender structural member, and its cross-section can have any suitable configuration, such as circular, rectangular, or polygonal. The multiple horizontal bars 101 and the multiple vertical bars 102 are arranged in a crisscross pattern within the same horizontal plane to form multiple storage layers 10. The multiple vertical bars are arranged along a vertical direction, i.e., the height direction h, to connect the multiple storage layers 10, thereby connecting the storage rack 1 into a whole. The multiple horizontal bars 101, the multiple vertical bars 102, and the multiple vertical bars 103 enclose multiple cubic spaces within the storage rack 1, each of which defines a storage position 100.

[0064] Furthermore, according to some embodiments of the present application, the crossbars 101 in each storage layer 10 have a crossbar extension 201 extending outward from one side of the storage rack 1. The interactive rack 2 also includes a plurality of interactive rack longitudinal rods 202 and a plurality of interactive rack vertical rods 203. Each interactive rack longitudinal rod 202 extends along the width direction b, and each interactive rack vertical rod 203 extends along the height direction h. The plurality of interactive rack longitudinal rods 202 and the crossbar extension 201 are arranged in a crisscross pattern within the same horizontal plane to form a plurality of interactive layers 20. The plurality of interactive rack vertical rods 203 are arranged in a vertical direction, i.e., the height direction h, to connect the plurality of interactive layers 20, thereby connecting the interactive rack 2 into a whole. Among them, multiple crossbar extensions 201, multiple interactive rack longitudinal rods 202, and multiple interactive rack vertical rods 203 enclose multiple cubic spaces in the same interactive layer 20, wherein the interior or top of one of the cubic spaces defines an interactive position 200. For example, in a cube near the outside, the interactive position of the upper layer can be defined by the top surface of the cube space of the lower layer. In this way, the cube of the lower layer has a top surface, and the cube with a top surface does not serve as an interactive position. Among them, in two adjacent interactive layers 20, the interactive positions 200 are staggered along the extension direction of the crossbar extension 201, that is, the length direction a, and along the extension direction of the interactive rack longitudinal rods 202, that is, the width direction b, so that the interactive positions 200 of any adjacent layers are staggered with each other in the height direction h, so that the container can enter any interactive position 200 from top to bottom.

[0065] Furthermore, in one embodiment, the first track 11 is disposed on the longitudinal rod 102 . For example, in a specific embodiment, a track is formed on the upper surface of the longitudinal rod 102 to define the first track 11 .

[0066] Furthermore, in one embodiment, the second track 12 is disposed on the crossbar 101 and the crossbar extension 201. For example, in one specific embodiment, the upper surfaces of the crossbar 101 and the crossbar extension 201 are each formed with interconnected tracks to define the second track 12. This arrangement allows the second track 12 to extend along the length direction a and the first track 11 to extend along the width direction b within the same plane, crisscrossing each other to form a track network within the same plane. The transport unit 3 traveling above can transport containers to any storage location 100.

[0067] In a specific embodiment, from the top surface of the interactive rack 2 downward, the interactive layers of the N+1 to 2N layers are spaced one cubic space away from the storage rack relative to the interactive layers 20 of the 1 to N layers, and the interactive layers of the 2N+1 to 3N layers are spaced one cubic space away from the storage rack relative to the interactive layers of the N+1 to 2N layers. Wherein, N is the number of cubic spaces along the extension direction of the longitudinal rods of the interactive rack, i.e., the width direction b. Figures 1 to 4 As shown in the figure, for example, along the width direction b, the number of cubic spaces is 3. From the top downward, the 4th to 6th interactive layers are spaced one cubic space away from the 1st to 3rd interactive layers, and the 7th to 9th interactive layers are spaced one cubic space away from the 4th to 6th interactive layers. With this arrangement, each interactive position 200 is open above. At the same time, since the rods constituting the interactive rack 2 form a space that allows containers to pass through, the container can enter any interactive position 200 from top to bottom.

[0068] In a specific embodiment, the interactive layers 20 of the 1st to Nth layers are arranged adjacent to the storage racks.

[0069] According to some embodiments of the container storage and retrieval system, a shelf 13 is further provided on the vertical rod 103 of the storage rack 1, and a lifting assembly 321 is further provided on the second transport device 32. The lifting assembly 321 can lift the load-bearing portion 320 to a position higher than the shelf 13. The first track 11 is connected to multiple shelves 13 along the extension direction of the vertical rod 102, that is, the width direction b. When storing containers, Figure 6 As shown, when the lifting assembly 321 is raised, the carrying portion 320 and the container 900 thereon can be lifted to a position higher than the shelf 13. At this time, as shown in FIG. Figure 7 As shown, the lifting assembly 321 is retracted. Since the width of the container 900 is greater than the width of the carrying portion 320 , the container 900 can be carried on the shelf 13 to complete the storage of the container 900 .

[0070] According to some embodiments of the container access system, Figure 1As shown, it also includes a lifting system 4, which can be a crane as shown in the figure, which is arranged above the interactive rack 2 and is used to lift the container from top to bottom to the interactive position 200.

[0071] On the other hand, according to some embodiments of the present application, a yard is also provided, which includes a ground transport vehicle 5 and a container access system as described in one or more of the previous embodiments, and the container is lifted from the ground transport vehicle 5 to the interaction position 200 by the lifting system 4.

[0072] In a specific embodiment, at least one horizontal ground transport vehicle loading and unloading operation lane is provided on the ground below the yard interaction area.

[0073] In a specific embodiment, a group or more buffering shelves are provided on the ground below the interaction area of the yard for buffering operations between the interaction point of the container storage area and the ground horizontal transport vehicles.

[0074] On the other hand, according to some embodiments of the present application, a container access method is provided, which is used to access the container in the yard as described above. Figures 1 to 7 , the container access method includes the following steps:

[0075] a. 5 ground transport vehicles drive into the designated ground loading and unloading lanes in the interactive area;

[0076] b. The lifting device of the lifting system 4 lifts the container from the ground transport vehicle on the designated ground loading and unloading operation lane of the interactive area;

[0077] c. The lifting system places the container on the second transport device 32 at the designated interactive position;

[0078] d. The second transport device 32 returns to the first transport device 31 with the container;

[0079] e. The first transport device 31 carries the second transport device 32 and the container along the second track 12 of the layer to the designated container cargo space; it can be understood that the container cargo space can be understood as a row of storage spaces with the same width direction b position where the storage space 100 where the container is to be stored is located.

[0080] f. The second transport device 32 uses its own jacking assembly 321 to lift the container and ensure that the bottom of the container is higher than the upper surface of the container shelf 13 in the container cargo space;

[0081] g. The second transport device 32 carries the container away from the first transport device 31 along the third track 33 on the first transport device 31 and enters the designated storage location 100 along the first track 11 at the container cargo area. Once in position, the second transport device 32 uses its own lifting assembly 321 to lower the container so that the bottom of the container is securely placed on the container shelf 13.

[0082] h. After the lifting assembly 321 is separated from the bottom surface of the container, the second transport device 32 moves away from the designated storage position 100 and enters the upper surface of the first transport device 31, and the container storage operation process is completed.

[0083] The process of unpacking boxes is basically the opposite of this and will not be described here.

[0084] Each interaction position of this container storage and retrieval system can operate independently without affecting the interaction positions of adjacent containers. It can realize direct storage and retrieval of containers without the need for the traditional container turning and sorting processes in the yard, reducing the frequency of equipment operation and the difficulty of container position management.

[0085] The stable structure of the container storage and retrieval system can greatly increase the number of stacking layers in the container space, while solving the instability of the containers after being stacked.

[0086] The staggered layout of this container storage and retrieval system ensures that each floor has a dedicated, overhead crane with direct access to interactive operation points without physical interference, which is more conducive to the realization of container in-and-out transshipment and intelligent yard operation management.

[0087] The storage locations of this container storage and retrieval system can expand the yard capacity in the longitudinal, transverse and height directions, and the yard interaction area at the corresponding end can also be expanded synchronously by increasing the number of staggered interaction points.

[0088] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.
