Description

Technical Field

[0001] This utility model relates to the field of transportation equipment and facilities technology, and in particular to an automated container terminal double-layer three-dimensional storage yard. Background Technology

[0002] Currently, automated container yards play a vital role in the modern logistics system. They utilize advanced technologies and equipment to efficiently manage and operate containers, thereby improving the efficiency and effectiveness of the entire logistics supply chain.

[0003] Existing automated container yards include parallel, vertical, and U-shaped yards. All three types of yard operations operate in a horizontal mode, meaning that the yard cranes, quay cranes, internal trucks, and external trucks are all located on the ground. In this layout, when unloading containers from ships, the containers must go through three stages in sequence: quay crane unloading (downward operation), internal truck transportation (horizontal operation), and yard crane stacking (upward and downward operation).

[0004] When loading containers onto ships, the process involves three steps: the quay crane hoisting the containers down onto the inner trucks (upward and downward operations), the inner trucks transporting the containers (horizontal operations), and the quay crane loading (upward and downward operations).

[0005] Taking the unloading of containers from a ship to a yard (i.e., unloading operations) as an example, see [link to relevant documentation]. Figure 1a As shown, with the quayside as the boundary, the container will undergo five displacements: the first displacement X1 is implemented when the quay crane vertically lifts the container from the height to the inner truck on the surface of the terminal yard; the second displacement X2 is implemented when the inner truck transports the container to the yard; the third displacement X3 is implemented when the yard crane lifts the container to the designated height (i.e., the height corresponding to the position of the container to be placed in the yard); the fourth displacement X4 is implemented when the container is horizontally moved to the position of the container to be placed in the yard (i.e., the designated container position); and the fifth displacement X5 is implemented when the container is vertically lifted to the designated container position. From the five displacements, it can be seen that there are repetitive energy consumption paths between the three displacement segments X1, X2, and X5, with a repetitive path length of 2X. 3。 Furthermore, loading operations are the reverse of unloading operations, which will not be elaborated further. Therefore, regardless of whether it is unloading or loading operations, containers have repeated paths in the vertical direction (i.e., repeated paths of container lifting and lowering), meaning that the process of containers moving from the ship to the yard involves repeated vertical displacement, increasing unnecessary energy consumption.

[0006] In addition, vertical yards compress the working area of ​​internal and external container trucks, enabling separate operations for them. Since the yard uses the horizontal movement of the yard crane to replace the work of internal and external container trucks in the container area, the yard operation efficiency is reduced. In contrast, in horizontal yards and U-shaped yards, if internal and external container trucks operate simultaneously, there will be intersections, which will inevitably affect the operation efficiency.

[0007] In addition, there is currently a positioning problem between the quay crane and the container truck (including the inner and outer container trucks): during each loading and unloading, the container truck needs to adjust its position according to the position of the quay crane, and at the same time, the quay crane also needs to adjust the position of the spreader according to the position of the container truck, which significantly increases the operation time.

[0008] Therefore, there is an urgent need to develop a technology that can solve the above-mentioned technical problems. Utility Model Content

[0009] The purpose of this invention is to address the technical deficiencies of existing technologies by providing an automated double-layer three-dimensional container terminal yard.

[0010] Therefore, this utility model provides an automated container terminal double-layer three-dimensional yard, including an upper platform, a lower platform and pillars;

[0011] The upper and lower platforms are distributed at alternating vertical intervals.

[0012] Directly behind the lower platform are container ships;

[0013] The upper and lower platforms are connected on opposite sides by multiple vertically distributed pillars;

[0014] The lower platform has multiple container storage areas that are horizontally spaced and vertically distributed.

[0015] The upper platform has an opening above each container storage area on the lower platform, which is equipped with a hollow hoisting operation area.

[0016] The upper platform is equipped with at least one yard crane above each hoisting operation area;

[0017] The top of the upper platform has multiple internal container trucks;

[0018] The lower platform, located on the side closest to the container ship, is equipped with at least one quay crane.

[0019] The top of the lower platform has multiple external container trucks;

[0020] A quay crane is used to lift containers from a container ship onto an inner truck on an upper platform.

[0021] Internal container trucks are used to travel on the upper platform to transport containers between quay cranes and yard cranes;

[0022] A yard crane is used to perform container lifting operations via spreaders suspended on it and through a hollow lifting work area.

[0023] As can be seen from the technical solution provided by this utility model above, compared with the prior art, this utility model provides an automated container terminal double-layer three-dimensional yard. Its double-layer structure design is scientific. Through the physical isolation of the upper and lower layers, the separation and parallel operation of the inner and outer container trucks are realized, which improves the efficiency of vehicle operation and has significant practical significance.

[0024] By applying this utility model, the double-layer design reduces the working path of the quay crane and solves the core problem that restricts the efficiency of container operation.

[0025] By applying this utility model, the double-layer design reduces the repeated paths of container lifting and lowering, reduces the energy consumption of yard operations, and in particular fills the gap in the three-dimensional layout of automated container yards.

[0026] In addition, the external positioning base of the quay crane and yard crane designed in this utility model will move with the quay crane and yard crane, and the inner truck can drive directly onto the external positioning base, so that the inner truck is located directly under the quay crane and quay crane spreader. There is no need to adjust the position of the quay crane or yard crane spreader according to the position of the truck, thus greatly reducing the positioning time between the quay crane / yard crane and the truck.

[0027] In addition, the automated container terminal double-layer three-dimensional yard provided by this utility model is specially designed with charging walls and charging interfaces for internal trucks, which enables internal trucks to charge while operating. There is no need to set up special charging piles or battery swapping stations in the operating area. Therefore, it can effectively solve the charging and battery swapping problem of electric internal trucks, and can eliminate the need for special charging piles and battery swapping stations, further increasing the operating time of internal trucks.

[0028] In summary, this utility model addresses the technical shortcomings of existing automated container yards, such as horizontal operation modes, long positioning times between quay cranes and container trucks, time-consuming charging, and large land occupation. It proposes a novel, double-layer, three-dimensional container yard solution. Applying this utility model can significantly improve the operational efficiency of automated container terminals.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0050] See Figure 1b , Figures 2a to 2b , Figures 3 to 4 , Figures 5a to 5f , Figures 6a to 6b , Figure 7 , Figures 8a to 8b This utility model provides an automated container terminal double-layer three-dimensional yard, including an upper platform 1, a lower platform 2 and support columns 3;

[0051] Upper platform 1 and lower platform 2 are distributed vertically and alternately.

[0052] Directly behind the lower platform 2 is the container ship 10;

[0053] The upper platform 1 and the lower platform 2 are connected on opposite sides by multiple vertically distributed support columns 3;

[0054] Among them, the lower platform 2 is equipped with multiple container storage areas 7 that are horizontally spaced and vertically distributed;

[0055] Among them, the upper platform 1 is located above each container stacking area 7 of the lower platform 2, and a hollow hoisting operation area 9 is set up (i.e., an open opening area without platform panels to block it).

[0056] The upper platform 1 is equipped with at least one (e.g., two) yard cranes 4 above each hoisting operation area 9;

[0057] The top of the upper platform 1 has multiple internal container trucks 5;

[0058] The lower platform 2 is located on the side closest to the container ship 10 (i.e., Figure 3 At least one quay crane 11 is installed on the rear side (as shown);

[0059] The top of the lower platform 2 has multiple external container trucks 6;

[0060] The quay crane 11 is used to lift containers from the container ship 10 onto the inner truck 5 of the upper platform 1;

[0061] Internal container truck 5 is used to travel on the upper platform 1 to transport containers between the quay crane 11 and the yard crane 4;

[0062] It should be noted that automated container terminals are a type of terminal that has been widely adopted in modern logistics systems. The technical solution of this utility model is specifically designed with a double-layer three-dimensional storage yard. Through the physical isolation of the upper and lower layers, the separation and parallel operation of internal and external container trucks are realized, thereby improving the efficiency of vehicle operation.

[0063] It should be noted that the outer container truck 6 is used to travel on the lower platform 2 and cooperate with the yard crane 4 to carry out container hoisting and unloading operations (i.e., loading and unloading operations) between itself and the container storage area 7 on the lower platform 2.

[0064] It should also be noted that the outer container truck 6, which travels on the lower platform 2, is used to transport containers from the terminal's yard (e.g., container storage area 7) to various logistics centers outside the terminal, or to transport containers from outside the container terminal to the terminal's yard (e.g., container storage area 7). On the lower platform 2, the outer container truck 6 works in conjunction with the container loading and unloading operations of the yard crane 4 to help complete the collection and distribution operations.

[0065] It should be noted that the yard crane 4 is located on the upper platform 1, and the inner container truck 5 travels on the upper platform; the outer container truck 6 travels on the lower platform 2, and the quay crane 11 is located on the lower platform 2.

[0066] The yard crane 4 is used to perform container lifting operations via the spreader 8 suspended on it and through the hollow lifting operation area 9.

[0067] In this utility model, specifically, the container hoisting operation includes a first hoisting operation and / or a second hoisting operation;

[0068] The first type of lifting operation is as follows: the spreader 8 passes through the hollow lifting operation area 9, and then the lifting and unloading operation of the container is carried out between the inner truck 5 on the upper platform 1 and the container stacking area 7 on the lower platform 2.

[0069] It should be noted that, for the first type of lifting operation, for example, the yard crane 4 can use the spreader 8 suspended on it and the hollow lifting operation area 9 to lift the container on the inner truck 5 below or the container stacking area 7 below, and then carry out the lifting and unloading operation between the inner truck 5 on the upper platform 1 and the container stacking area 7 on the lower platform 2.

[0070] The second type of lifting operation is as follows: the spreader 8 passes through the hollow lifting operation area 9, and then the container is lifted and unloaded between the external container truck 6 on the lower platform 2 and the container stacking area 7 on the lower platform 2 (i.e., loading and unloading operation).

[0071] It should be noted that, regarding the second type of lifting operation, for example, the yard crane 4 can use the spreader 8 suspended on it to lift the container on the outer truck 6 of the lower platform 2 or the container storage area 7 below, and then carry out the lifting and unloading operation between the outer truck 6 on the lower platform 2 and the container storage area 7 on the lower platform 2.

[0072] Therefore, in this utility model, the spreader 8 suspended on the top of the yard crane 4 can realize the lifting and unloading operations between the inner container truck 5 on the upper platform 1 and the container stacking area 7 on the lower platform 2 through the hollow lifting operation area 9, or realize the lifting and unloading operations between the outer container truck 6 on the lower platform 2 and the container stacking area 7 on the lower platform 2.

[0073] In this utility model, it should be noted that the support columns 3 are spaced apart on the lower platform 2 and serve as connecting supports between the upper and lower platforms to support the stability of the upper platform 1.

[0074] In this utility model, it should be noted that the inner container truck 5 and the yard crane 4 can run on the upper platform 1; the outer container truck 6 runs on the lower platform 2. The outer container truck 6 is used to cooperate with the yard crane 4 on the lower platform 2 to carry out container loading and unloading operations and complete the collection and distribution operations.

[0075] In this invention, specifically, the lower platform 2 is preferably the ground of the front yard of the quay where the container ship 10 is moored. The inner truck 5, yard crane 4, outer truck 6, and quay crane 11 are commonly used equipment in existing container terminals and will not be described in detail here.

[0076] In this utility model, specifically, the hoisting operation area 9 is located directly above the container stacking area 7, and the center points of the two are located on the same vertical central axis.

[0077] In this utility model, specifically, the lateral width and longitudinal width of the hoisting operation area 9 are greater than the lateral width and longitudinal width of the container stacking area 7, respectively.

[0078] In practice, the lateral width of the hoisting operation area 9 is greater than the sum of the lateral width of the container stacking area 7 and the width of the two external container trucks 6.

[0079] The longitudinal width of the hoisting operation area 9 is greater than the sum of the longitudinal width of the container stacking area 7 and the width of the two external container trucks 6.

[0080] In this utility model, specifically, the lower end of the field bridge 4 is connected to the external positioning base 121 of the field bridge;

[0081] The lower edge of the external positioning base 121 of the bridge fits against the upper surface of the upper platform 1 (while maintaining a preset vertical spacing, such as a vertical spacing of 5 cm).

[0082] The external positioning base 121 of the yard bridge is used to place the internal container truck 5;

[0083] In practice, the external positioning base 121 of the yard bridge is connected to the lower middle part of the yard bridge 4 through the first connecting steel plate 131;

[0084] The external positioning base 121 of the yard crane is located directly below the moving path of the spreader 8 on the yard crane 4 (i.e. the moving path of the spreader on the gantry).

[0085] In specific implementation, a first parking groove 141 is provided on the top of the external positioning base 121 of the yard bridge;

[0086] The first parking recess 141 is used to park the inner container truck 5;

[0087] On both sides of the first parking recess 141, there is an inclined first parking ramp 1410;

[0088] Two first parking ramps 1410 are symmetrically distributed around the first parking recess 141, and the height of the first parking ramps 1410 decreases as the distance between them and the first parking recess 141 increases.

[0089] Furthermore, the slope of the first parking ramp 1410 ranges from 10° to 25°.

[0090] Furthermore, a first arc transition portion 1411 is provided between the first parking recess 141 and each first parking ramp 1410;

[0091] The height of the first arc transition portion 1411 increases as the distance between it and the first parking groove 141 increases;

[0092] The highest point of the first arc transition section 1411 is lower than the highest point of the adjacent first parking ramp 1410.

[0093] Based on the above design, the inner truck 5 can easily enter the first parking groove 141 of the external positioning base 121 of the yard bridge, which not only facilitates parking, but also constrains the position of the inner truck 5 through the first parking ramps 1410 on both sides of the first parking groove 141.

[0094] It should be noted that the external positioning base 121 of the yard bridge is connected to the lower end of the yard bridge 4 via the first connecting steel plate 131 and is centrally positioned to ensure the synchronization of the movement of the external positioning base 121 and the yard bridge 4. This ensures that the external positioning base 121 can be located directly below the spreader of the yard bridge 4, so that when the spreader reaches above the inner truck 5, no further horizontal adjustment is required, and vertical operation can be carried out directly. The internal concave design of the external positioning base 121 ensures that the front and rear tires of the inner truck 5 are precisely positioned in the first parking recess 141, reducing the time required for the inner truck 5 to adjust its parking position according to the position of the yard bridge 4 (i.e., no further adjustment of the spreader position of the yard bridge 4 is needed based on the inner truck 5, achieving vertical alignment).

[0095] In this utility model, specifically, the quay crane 11 is connected to the external positioning base 122 of the quay crane in the part above the top surface of the upper platform 1 (i.e., the part with a height higher than the middle and upper part of the upper platform 1) through a connecting structure (e.g., a steel structure, specifically the second connecting steel plate 132).

[0096] The external positioning base 122 of the quay crane is used to park the internal container truck 5;

[0097] The lower edge of the external positioning base 122 of the quay crane fits against the upper surface of the upper platform 1 (while maintaining a preset vertical spacing, such as a vertical spacing of 5 cm).

[0098] It should be noted that the external positioning base of the yard crane and the external positioning base of the quay crane are connected to the yard crane 4 and the quay crane 11 respectively, and move together with the yard crane 4 or the quay crane 11 respectively.

[0099] In practice, the external positioning base 122 of the quay crane is connected to the lower middle part of the quay crane 11 through the second connecting steel plate 132.

[0100] The external positioning base 122 of the quay crane is located directly below the movement path of the spreader of the quay crane 11 (i.e., the movement path of the spreader on the gantry).

[0101] In practice, a second parking recess 142 is provided on the top of the external positioning base 122 of the quay crane;

[0102] The second parking recess 142 is used to park the inner container truck 5;

[0103] On both sides of the second parking recess 142, there is an inclined second parking ramp 1420;

[0104] Two second parking ramps 1420 are symmetrically distributed around the second parking recess 142, and the height of the second parking ramps 1420 decreases as the distance between them and the second parking recess 142 increases.

[0105] Furthermore, the slope of the second parking ramp 1420 ranges from 10° to 25°.

[0106] Furthermore, a second arc transition portion 1421 is provided between the second parking recess 142 and each second parking ramp 1420;

[0107] The height of the second arc transition portion 1421 increases as the distance between it and the second parking groove 142 increases;

[0108] The highest point of the second arc transition section 1421 is lower than the highest point of the adjacent second parking ramp 1420.

[0109] Based on the above design, the inner container truck 5 can easily enter the second parking groove 142 of the external positioning base 122 of the quay crane, which not only facilitates parking, but also constrains the position of the inner container truck 5 through the second parking ramps 1420 on both sides of the second parking groove 142.

[0110] It should be noted that the external positioning base 122 of the quay crane is connected to the portion of the quay crane 11 above the upper platform 1 via the second connecting steel plate 132 and is centrally positioned, ensuring the synchronization of the movement of the external positioning base 122 and the quay crane 11. This ensures that the external positioning base 122 can be located directly below the spreader of the quay crane 11, so that when the spreader reaches above the inner truck 5, no further horizontal adjustment is needed, and vertical operation can be carried out directly. The concave design of the external positioning base 122 ensures that the front and rear tires of the inner truck 5 are precisely positioned in the second parking recess 142, reducing the time required for the inner truck 5 to adjust its parking position according to the position of the quay crane 11 (i.e., no further adjustment of the spreader position of the quay crane 11 is needed based on the inner truck 5, achieving vertical alignment).

[0111] Therefore, given that the external positioning base 122 of the quay crane is connected to the quay crane 11 by a steel structure (e.g., the second connecting steel plate 132), and its lower edge is attached to the upper surface of the upper platform 1, the external positioning base 122 of the quay crane moves with the quay crane 11; when loading and unloading containers, the inner truck 5 drives onto the external positioning base 122 of the quay crane, and after the spreader of the quay crane 11 reaches the external positioning base 122 of the quay crane, it does not need to move horizontally and can directly carry out vertical loading and unloading operations.

[0112] In specific implementation, the automated container terminal double-layer three-dimensional yard provided by this utility model includes the following working modes for unloading containers from the ship to the yard (i.e., the operation mode of the upper platform 1):

[0113] First, the inner truck 5 drives onto the external positioning base 122 of the quay crane 11 connected to the quay crane 11;

[0114] Then, the containers on container ship 10 are lifted by the spreader of quay crane 11 and unloaded onto inner truck 5;

[0115] Then, the inner truck 5 travels on the passage of the upper platform 1 to a yard crane 4, and the container is lifted from the inner truck 5 by the spreader 8 of the yard crane 4, and then lifted into the container storage area 7 of the lower platform 2 through the hollow lifting operation area 9.

[0116] In this utility model, specifically, a charging wall 15 is installed next to the hoisting operation area 9;

[0117] The charging wall 15 is equipped with multiple charging sockets that are evenly spaced.

[0118] The charging interface 16 on the inner card 5 is used to connect to the charging socket on the charging wall 15 to realize the charging function.

[0119] In practice, the charging wall 15 is set parallel to the longitudinal straight edge of the hoisting operation area 9.

[0120] It should be noted that the charging socket on the charging wall 15 is connected to an external AC power grid (such as a 220V AC power grid) and is powered by the AC power grid.

[0121] It should be noted that the charging wall 15 is set up on the longitudinal straight edge of the hoisting operation area 9. The inner truck 5 is designed with unfoldable charging interfaces 16 on both sides. When the inner truck is driving next to the charging wall 15 or stopping next to the charging wall 15 for loading and unloading operations, the inner truck can be charged by unfolding the charging interface and connecting the positive and negative terminals of the charging wall 15 and the charging interface 16.

[0122] To better understand the technical solution of this utility model, the working principle of this utility model is explained below.

[0123] The storage yard of this utility model is mainly used to realize non-intersection operation of internal and external container trucks in automated container terminals (internal and external container trucks are located on platforms at different heights, and their travel paths will not overlap), and can significantly reduce the movement path of containers in the vertical operation direction.

[0124] It should be noted that, based on the double-layer three-dimensional storage yard designed in this utility model, taking the unloading of containers from the ship to the storage yard (i.e., unloading operation) as an example, see [link to relevant documentation]. Figure 1b As shown, the container will undergo three displacements, with the shoreline as the boundary: the first displacement X is implemented when the quay crane vertically lifts the container from the height to the inner truck on the upper platform 1. 10 The second displacement X carried out on the upper platform 1 when the container truck is transported to the yard. 20 The third displacement X implemented when vertically lowering the container to the designated position. 50 (like Figure 1b As shown), compared to existing technologies (such as...), the container movement path... Figure 1a As shown), this utility model eliminates the repetitive path 2X3 that existed in the prior art.

[0125] Among them, the design of external positioning bases for quay cranes and yard cranes solves the problem of long positioning time when loading and unloading containers onto inward container trucks, and further improves the operational efficiency of the double-layer three-dimensional yard of the automated container terminal.

[0126] Furthermore, the automated container terminal double-layer three-dimensional yard of this utility model consists of an upper platform, a lower platform, and support columns; the upper platform is connected to the quay crane, and the inner container trucks and yard cranes operate on the upper platform; the lower platform is the ground of the front yard of the terminal, and the outer container trucks operate on the lower platform; the support columns connect and support the upper and lower platforms; the yard cranes and quay cranes have external positioning bases that are connected to the yard cranes and quay cranes respectively, and move with them; this utility model fully utilizes the mobility of the inner and outer container trucks, realizes the physical isolation between the inner and outer container trucks, and effectively reduces the repeated vertical displacement of containers during the process of moving from the ship to the yard.

[0127] The present invention provides an external positioning base for the quay crane and an external positioning base for the yard crane in the double-layer three-dimensional yard of the automated container terminal, which reduces the positioning time of the inner truck under the quay crane and the yard crane, as well as the positioning time of the quay crane and the yard crane for loading and unloading containers onto the inner truck.

[0128] This utility model features a charging wall and charging interface design for internal container trucks in a double-layer three-dimensional yard of an automated container terminal, enabling internal container trucks to charge while operating, eliminating the need for dedicated charging piles or battery swapping stations in the operating area.

[0129] To better understand the technical solution of this utility model, the following detailed description is provided in conjunction with specific embodiments. This utility model provides an automated container terminal with a double-layer, three-dimensional storage yard, used for the collection and distribution of containers at the port.

[0131] Example 1 illustrates the implementation of this utility model by taking the unloading of containers from a ship to a yard and then transferring the containers out of the yard as an example.

[0132] In Embodiment 1, the present invention includes a first working mode: a working mode of unloading containers from a ship to a yard, and then transferring the containers out of the yard, which includes the following operations:

[0133] The first phase involves the ship-to-yard operation: First, the inner truck 5 travels to the external positioning base 122 of the quay crane 11. Then, the containers on the container ship 10 are lifted and unloaded onto the inner truck 5 by the spreader of the quay crane 11. Then, the inner truck 5 travels on the passage of the upper platform 1 to a yard crane 4. The spreader 8 of the yard crane 4 lifts the containers from the inner truck 5 and then lifts them into the container storage area 7 of the lower platform 2 through the hollow lifting operation area 9.

[0134] In the second phase, the operation from the yard to the off-site is carried out: the external container truck 6 enters the yard at the front of the terminal and drives to the container storage area 7 of the lower platform 2. The spreader 8 of the yard crane 4 lifts the container onto the external container truck 6, and then the container is transported to the off-site hinterland by the external container truck 6.

[0135] Example 2.

[0136] Example 2 illustrates the implementation of this utility model using container collection at the port, loading and unloading of containers, and port clearance operations as examples.

[0137] In Embodiment 2, the present invention includes a second working mode: a working mode in which containers are unloaded to the yard by external trucks, and then loaded onto the ship from the yard. This working mode includes the following operations:

[0138] In the first phase, the off-site to container yard operation is carried out: the external container truck 6 enters the container yard at the front of the terminal and drives to the container storage area 7 on the lower platform 2. The spreader 8 of the yard crane 4 passes through the hollow lifting operation area 9, and then the spreader 8 of the yard crane 4 lifts the container on the external container truck 6 into the container storage area 7.

[0139] The second stage involves the execution of the yard-to-ship operation: First, the inner truck 5 travels on the upper platform 1 to a yard crane 4. The spreader 8 of the yard crane 4 lifts the container in the container storage area 7 onto the inner truck 5 through the hollow lifting operation area 9. Then, the inner truck 5 travels to the external positioning base 122 of the quay crane 11, which is connected to the quay crane 11, and is lifted onto the container ship 10 by the spreader of the quay crane 11.

[0140] As can be seen from the above embodiments, the double-layer structure design of the yard in this utility model changes the operation organization of the quay crane 11, yard crane 4, inner container truck 5 and outer container truck 6.

[0141] Compared with the prior art, by applying this utility model, the operation path for lifting and unloading containers at the quay end of the quay crane 11 is: from the quay crane 11 to the upper platform 1 above the lower platform 2. Compared with the current original quay crane operation path, which is from the quay crane to the lower platform 2 on the ground, since the upper platform 1, which is the destination for container unloading, is located above the lower platform 2, the operation path of the quay crane 11 (e.g., the vertical movement path of the spreader) is shortened.

[0142] By applying this invention, for the yard crane 4, since the inner truck 5 and outer truck 6 can enter the yard area (i.e., the inner truck 5 can enter the area next to the hoisting operation area 9 above the container storage area 7, and the outer truck 6 can enter the area next to the container storage area 7 on the lower platform 2), the transportation task of the yard crane 4 along its matching track (for the track, the original prior art was laid on the lower platform 2 on the ground, while in this invention it is laid on the upper platform 1) is replaced. Therefore, the displacement of the yard crane 4 along its matching track is greatly shortened. The yard crane 4 is located on the upper platform 1, and can complete the loading and unloading of containers on the inner truck 5, as well as the loading and unloading of containers on the outer truck 6 and the container transfer operation in the container storage area 7 through the hollow hoisting operation area 9.

[0143] By applying this invention, the inner container truck 5 can enter the yard area of ​​the upper platform 1 (i.e., the area next to the hoisting operation area 9 above the container storage area 7 of the lower platform 2) without encountering the outer container truck 6, thus improving operational efficiency. Similarly, the outer container truck 6 can enter the yard area on the lower platform 2 (i.e., the area next to the container storage area 7) without encountering the inner container truck 5, further improving operational efficiency.

[0144] Compared with existing technologies, the automated container terminal double-layer three-dimensional storage yard provided by this utility model has the following beneficial effects:

[0145] 1. The automated container terminal double-layer three-dimensional yard provided by this utility model realizes the separation and parallel operation of internal and external container trucks through the physical isolation of the upper and lower layers, thereby improving the efficiency of vehicle operation;

[0146] 2. The double-layer design of the storage yard in this utility model reduces the operating path of the quay crane and solves the core problem that restricts the efficiency of container operation.

[0147] 3. The double-layer design of the yard in this utility model reduces the repeated paths of container lifting and unloading, and reduces the energy consumption of yard operations;

[0148] 4. Currently, there are no double-layer layout container yards at home and abroad. This utility model fills the gap in three-dimensional layout of automated container yards.

[0149] 5. The external positioning base for quay cranes and yard cranes designed in this utility model significantly reduces the positioning time between quay cranes / yard cranes and container trucks;

[0150] 6. The internal truck charging wall and charging interface designed in this utility model enable the internal truck to charge while operating;

[0151] 7. Due to its reasonable structural design and the fact that many of its components can be assembled using prefabricated modules, this utility model is convenient for upgrading and transforming existing wharves.

[0152] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
