Description

Technical Field

[0001] The present invention relates to the technical field of transportation equipment and facilities, and in particular to a double-layer three-dimensional yard of an automated container terminal. Background Art

[0002] At present, automated container yards play a vital role in the modern logistics system. With the help of advanced technology and equipment, they can efficiently manage and operate containers, thereby improving the efficiency and benefits of the entire logistics supply chain.

[0003] The existing automated container yards include parallel yards, vertical yards and U-shaped yards. All three types of yard operations are horizontal, that is, the yard crane, quay crane, internal container truck and external container truck are all located on the ground. In this layout, when the container is unloaded from the ship, it is required to go through three steps: unloading by the quay crane (downward operation), transport by the internal container truck (horizontal operation) and stacking by the yard crane (upward and downward operation);

[0004] When loading containers, the container must be lowered by the yard crane and placed on the inner container truck (upward and downward operation), transported by the inner container truck (horizontal operation), and loaded by the quay crane (upward and downward operation).

[0005] Take the unloading of containers from a ship to a storage yard (i.e. unloading operation) as an example, see Figure 1a As shown in the figure, with the shore as the boundary, the container will experience five displacements: the first displacement X1 implemented when the quay crane vertically lowers the container from high altitude to the inner container truck on the dock yard, the second displacement X2 implemented when the inner container truck transports the container to the yard, the third displacement X3 implemented when the yard crane lifts the container to the specified height (i.e., the height corresponding to the position of the container to be placed in the yard), the fourth displacement X4 implemented when the container is horizontally moved to the position of the container to be placed in the yard (i.e., the specified container position), and the fifth displacement X5 implemented when the container is vertically lowered to the specified container position. It can be seen from the five displacements that there are repeated energy consumption paths between the three displacements X1, X2, and X5, and the length of the repeated path is 2X 3。 In addition, loading is the reverse operation of unloading, which will not be described in detail. Therefore, regardless of unloading or loading, the container has repeated paths in the vertical direction (i.e., repeated paths of the container being hoisted up and down), that is, the process of the container moving from the ship to the yard has repeated displacement in the vertical direction, which increases unnecessary energy consumption.

[0006] In addition, the vertical yard compresses the operating areas of the inner and outer container trucks and realizes the separation of the inner and outer container trucks. Since the yard uses the horizontal movement of the yard bridge to replace the work of the inner and outer container trucks in the container area, the yard's operating efficiency is reduced. For the horizontal yard and U-shaped yard, if the inner and outer container trucks operate at the same time, there will be intersections, which will inevitably affect the operating efficiency.

[0007] In addition, there is still a positioning problem between the quay crane and the container truck (including the inner container truck and the outer container truck): during each loading and unloading, the container truck needs to adjust its position according to the position of the quay crane, and 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 technical problems. Summary of the invention

[0009] The purpose of the present invention is to provide a double-layer three-dimensional yard for an automated container terminal in view of the technical defects in the prior art.

[0010] To this end, the present invention provides a double-layer three-dimensional yard of an automated container terminal, comprising an upper platform, a lower platform and pillars;

[0011] The upper platform and the lower platform are spaced apart from each other.

[0012] Directly behind the lower platform, there is a container ship;

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

[0014] Among them, on the lower platform, there are multiple container storage areas that are spaced laterally and distributed longitudinally;

[0015] The upper platform is provided with a hollow lifting operation area at a position above each container storage area of ​​the lower platform;

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

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

[0018] Among them, the lower platform is provided with at least one quay crane on the side close to the container ship;

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

[0020] Quay cranes are used to lift containers from container ships to container trucks on the upper platforms;

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

[0022] The yard crane is used to perform container lifting operations through the spreaders suspended on it and through the hollow lifting operation area.

[0023] It can be seen from the technical solution provided by the present invention that, compared with the prior art, the present invention provides an automated container terminal double-layer stereoscopic yard, whose double-layer structure is scientifically designed, and through the physical isolation of the upper and lower double layers, the separation and parallel operation of the inner and outer container trucks are realized, thereby improving the efficiency of vehicle operation, which has great practical significance.

[0024] By applying the present invention, the double-layer design reduces the operation path of the quay crane, solving the core problem that restricts the efficiency of container operation;

[0025] By applying the present invention, the double-layer design reduces the repeated paths of container lifting and lowering, reduces the energy consumption of yard operations, and especially fills the gap in the three-dimensional layout of the automated container yard;

[0026] In addition, the external positioning base of the quay crane and yard crane designed in the present invention will move with the movement of the quay crane and yard crane, and the inner container truck can directly drive onto the external positioning base, so that the inner container truck is located directly under the quay crane and the quay crane spreader, and there is no need to adjust the position of the quay crane or the yard crane spreader according to the position of the container truck, thereby greatly reducing the positioning time between the quay crane, the yard crane and the container truck;

[0027] In addition, in the double-layer stereoscopic yard of the automated container terminal provided by the present invention, a charging wall and a charging interface are specially designed for the inner container trucks, so that the inner container trucks can be charged while operating, and there is no need to set up special charging piles or battery swap stations in the operating area. Therefore, the problem of charging and swapping of electric inner container trucks can be effectively solved, and special charging piles and battery swap stations can be eliminated, further increasing the operating time of the inner container trucks.

[0028] In summary, the present invention proposes a new type of double-layer three-dimensional yard solution to the technical defects of the existing horizontal operation mode of automated container yards, long positioning time between quay cranes and container trucks, time-consuming charging, and land occupation. By applying the present invention, the operating efficiency of automated container terminals can be significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] See also Figure 1b , Figure 2a to Figure 2b , Figure 3 to Figure 4 , Figure 5a to Figure 5f , Figure 6a to Figure 6b , Figure 7 , Figure 8a to Figure 8b , the present invention provides a double-layer three-dimensional yard of an automated container terminal, comprising an upper platform 1, a lower platform 2 and pillars 3;

[0051] The upper platform 1 and the lower platform 2 are spaced apart from each other;

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

[0053] The upper platform 1 and the lower platform 2 are connected on opposite sides by a plurality of vertically distributed pillars 3;

[0054] Among them, on the lower platform 2, there are multiple container storage areas 7 that are spaced laterally and distributed longitudinally;

[0055] The upper platform 1 is provided with a hollow lifting operation area 9 (i.e., an open opening area without being blocked by a platform plate) at a position above each container storage area 7 of the lower platform 2;

[0056] The upper platform 1 is provided with at least one (for example, two) field cranes 4 above each lifting operation area 9;

[0057] The top of the upper platform 1 is provided with a plurality of inner container trucks 5;

[0058] The lower platform 2 is located on the side close to the container ship 10 (i.e. Figure 3 At least one quay crane 11 is provided;

[0059] The top of the lower platform 2 is provided with a plurality of external container trucks 6;

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

[0061] The inner 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 the automated container terminal is a terminal that has been widely used in the modern logistics system. The technical solution of the present invention is to design a double-layer three-dimensional yard specifically for it. Through the physical isolation of the upper and lower double layers, the separation and parallel operation of the 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 lifting and unloading operations (i.e. loading and unloading operations) between it and the container storage area 7 on the lower platform 2;

[0064] It should also be noted that the external container truck 6, which travels on the lower platform 2, is used to transport containers from the terminal yard (such as the container storage area 7) to various logistics centers outside the terminal, or to transport containers outside the container terminal to the terminal yard (such as the container storage area 7). The external container truck 6 is on the lower platform 2, cooperating with the container loading and unloading operation of the yard crane 4 to help complete the collection and distribution operation.

[0065] It should be noted that the yard crane 4 is arranged 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 arranged on the lower platform 2.

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

[0067] In the present invention, in specific implementation, the container lifting operation includes the first lifting operation and / or the second lifting operation;

[0068] The first type of lifting operation is specifically: let the lifting device 8 pass through the hollow lifting operation area 9, and then carry out the lifting and unloading operation of the container between the inner container truck 5 on the upper platform 1 and the container storage area 7 on the lower platform 2;

[0069] It should be noted that, regarding the first type of lifting operation, for example, the yard crane 4 can use the suspended lifting device 8 thereon and the hollow lifting operation area 9 to allow the lifting device 8 to lift the container on the inner container truck 5 below or the container on the container storage area 7 below, and then perform lifting and unloading operations of the container between the inner container truck 5 on the upper platform 1 and the container storage area 7 on the lower platform 2.

[0070] The second lifting operation is specifically: allowing the lifting device 8 to pass through the hollow lifting operation area 9, and then performing lifting and unloading operations (i.e. loading and unloading operations) of the container between the outer container truck 6 on the lower platform 2 and the container storage area 7 on the lower platform 2.

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

[0072] Therefore, for the present invention, the sling 8 suspended on the top of the yard bridge 4 can realize the lifting and unloading operations of the container between the inner container truck 5 on the upper platform 1 and the container storage area 7 on the lower platform 2 through the hollow lifting operation area 9, or realize the lifting and unloading operations of the container between the outer container truck 6 on the lower platform 2 and the container storage area 7 on the lower platform 2.

[0073] In the present invention, it should be noted that the pillars 3 are arranged at intervals on the lower platform 2 and are the connecting supports between the upper and lower platforms, and are used to support the stability of the upper platform 1 .

[0074] In the present invention, 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, and 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 to complete the collection and distribution operations.

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

[0076] In the present invention, in a specific implementation, the lifting operation area 9 is located directly above the container storage area 7, and the center points of the two are located on the same vertical central axis.

[0077] In the present invention, in a specific implementation, the transverse width and the longitudinal width of the lifting operation area 9 are respectively greater than the transverse width and the longitudinal width of the container storage area 7 .

[0078] In specific implementation, the transverse width of the lifting operation area 9 is greater than the sum of the transverse width of the container storage area 7 and the width of the two external container trucks 6;

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

[0080] In the present invention, in a specific implementation, the lower end of the field bridge 4 is connected to the field bridge external positioning base 121;

[0081] The lower edge of the external positioning base 121 of the field bridge is in contact with the upper surface of the upper platform 1 (and maintains a preset vertical spacing, such as a vertical spacing of 5 cm);

[0082] The external positioning base 121 of the field crane is used to place the inner container truck 5;

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

[0084] The external positioning base 121 of the field bridge is located directly below the moving path of the spreader 8 on the field bridge 4 (that is, 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 field bridge;

[0086] The first parking groove 141 is used for parking the inner container truck 5;

[0087] Both sides of the first parking groove 141 are provided with an inclined first parking gentle slope 1410;

[0088] The two first parking gentle slopes 1410 are symmetrically distributed with the first parking recess 141 as the center, and the height of the first parking gentle slope 1410 decreases as the distance from 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 groove 141 and each first parking gentle slope 1410;

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

[0092] The highest position height of the first arc transition portion 1411 is lower than the highest position height of the adjacent first parking ramp 1410 .

[0093] Based on the above design, the inner container truck 5 can easily enter the first parking groove 141 of the external positioning base 121 of the yard bridge, which is not only convenient for docking, but also the position of the inner container truck 5 is constrained by the first parking gentle slopes 1410 on both sides of the first parking groove 141.

[0094] It should be noted that the external positioning base 121 of the field bridge is connected to the lower end of the field bridge 4 through the first connecting steel plate 131 and is arranged in the center, which ensures the synchronization of the movement of the external positioning base 121 of the field bridge and the field bridge 4, and ensures that the external positioning base 121 of the field bridge can be located directly below the hoist of the field bridge 4, so that when the hoist reaches the top of the inner container truck 5, there is no need to adjust the horizontal position, and vertical operation can be performed directly. Among them, the internal concave design of the external positioning base 121 of the field bridge can ensure that the front and rear tires of the inner container truck 5 are exactly located in the first parking groove 141, reducing the time that the inner container truck 5 needs to adjust the parking position according to the position of the field bridge 4 each time (that is, there is no need to adjust the position of the hoist of the field bridge 4 according to the inner container truck 5, and the upper and lower alignment has been achieved).

[0095] In the present invention, in a specific implementation, the quay crane 11 is connected to the quay crane external positioning base 122 through a connecting structure (such as a steel structure, specifically a second connecting steel plate 132) at a portion located above the top surface of the upper platform 1 (i.e., a portion higher than the middle and upper portion of the upper platform 1);

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

[0097] The lower edge of the external positioning base 122 of the quay crane is in contact with the upper surface of the upper platform 1 (and maintains 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 respectively connected to the yard crane 4 and the quay crane 11, and move with the yard crane 4 or the quay crane 11 respectively.

[0099] In specific implementation, the external positioning base 122 of the quay crane is connected to the middle part of the lower end 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 moving path of the spreader of the quay crane 11 (ie the moving path of the spreader on the gantry).

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

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

[0103] Both sides of the second parking groove 142 are provided with an inclined second parking gentle slope 1420;

[0104] The two second parking gentle slopes 1420 are symmetrically distributed with the second parking recess 142 as the center, and the height of the second parking gentle slope 1420 decreases as the distance from 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 groove 142 and each second parking gentle slope 1420;

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

[0108] The highest position height of the second arc transition portion 1421 is lower than the highest position height 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 is not only convenient for docking, but also the position of the inner container truck 5 is constrained by the second parking gentle slopes 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 part of the quay crane 11 above the upper platform 1 through the second connecting steel plate 132, and is arranged in the center, which ensures the synchronization of the movement of the external positioning base 122 of the quay crane and the quay crane 11, and ensures that the external positioning base 122 of the quay crane can be located directly below the spreader of the quay crane 11, so that when the spreader reaches the top of the inner container truck 5, there is no need to adjust the horizontal position, and vertical operation can be performed directly. Among them, the internal concave design of the external positioning base 122 of the quay crane can ensure that the front and rear tires of the inner container truck 5 are exactly located in the second parking groove 142, reducing the time that the inner container truck 5 needs to adjust the parking position according to the position of the quay crane 11 each time (that is, there is no need to adjust the position of the spreader of the quay crane 11 according to the inner container truck 5, and the upper and lower alignment has been achieved).

[0111] Therefore, given that the external positioning base 122 of the quay crane is connected to the quay crane 11 through a steel structure (such as the second connecting steel plate 132), and its lower edge is in contact with the upper surface of the upper platform 1, when the quay crane 11 moves, the external positioning base 122 of the quay crane moves with it; when loading and unloading containers, the inner container truck 5 travels onto the external positioning base 122 of the quay crane, and after the lifting device of the quay crane 11 reaches the external positioning base 12 of the quay crane, it does not need to move horizontally, and vertical loading and unloading operations can be carried out directly.

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

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

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

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

[0116] In the present invention, in a specific implementation, a charging wall 15 is arranged next to the hoisting operation area 9;

[0117] The charging wall 15 is provided with a plurality of charging sockets distributed at equal intervals;

[0118] The charging interface 16 provided on the inner collection card 5 is used to realize the charging function by connecting with the charging socket on the charging wall 15 .

[0119] In a specific implementation, the charging wall 15 is arranged parallel to the longitudinal straight edge of the lifting 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 (eg, a 220V AC power grid) and is powered by the AC power grid.

[0121] It should be noted that the charging wall 15 is arranged at the longitudinal straight edge of the lifting operation area 9, and expandable charging interfaces 16 are designed on both sides of the inner container truck 5. When the inner container truck is driving beside the charging wall 15 or stops beside the charging wall 15 for loading and unloading operations, the inner container truck can be charged by expanding the charging interface, and the positive and negative poles of the charging wall 15 and the charging interface 16 are correspondingly connected.

[0122] In order to more clearly understand the technical solution of the present invention, the working principle of the present invention is explained below.

[0123] The stacking yard of the present invention is mainly used to realize non-intersection operation of internal and external container trucks in an automated container terminal (the internal container trucks and the external container trucks are respectively located on platforms at different heights, and their travel paths do not overlap), and can significantly reduce the moving path of the container in the vertical operation direction;

[0124] It should be noted that the double-layer three-dimensional yard designed according to the present invention takes the unloading of containers from a ship to the yard (i.e., unloading operation) as an example, see Figure 1b As shown in the figure, with the shore as the boundary, the container will experience three displacements: the first displacement X when the quay crane vertically lifts the container from high altitude to the inner container truck on the upper platform 1 10 , the second displacement X implemented on the upper platform 1 when the inner container truck is transported to the yard 20 , the third displacement X when the container is vertically lowered to the designated container position 50 (like Figure 1b As shown), compared with the container movement path of the prior art (such as Figure 1a As shown), the present invention eliminates the repeated path 2X3 existing in the prior art implemented previously.

[0125] Among them, the design of the external positioning base of the quay crane and the yard crane solves the problem of long positioning time of the quay crane and the yard crane when loading and unloading containers on the inward container truck, and further improves the operating efficiency of the double-layer three-dimensional yard of the automated container terminal.

[0126] In addition, the double-layer three-dimensional yard of the automated container terminal of the present invention comprises an upper platform, a lower platform and pillars; the upper platform is connected to the quay crane, and the inner container trucks and yard cranes run on the upper platform; the lower platform is the ground of the yard in front of the terminal, and the outer container trucks run on the lower platform; the pillars are the connecting supports of the upper and lower platforms; the yard crane and the quay crane external positioning bases are respectively connected to the yard crane and the quay crane and move with them; the present invention fully mobilizes the mobility of the inner and outer container trucks, realizes the physical isolation of the inner and outer container trucks, and effectively reduces the repeated displacement of the container in the vertical direction in the process from the ship to the yard.

[0127] According to the present invention, the external positioning bases of the quay crane and the yard crane in the double-layer three-dimensional yard of the automated container terminal reduce the positioning time of the inner container truck under the quay crane and the yard crane, and the positioning time of the quay crane and the yard crane for loading and unloading containers onto the inner container truck.

[0128] According to the present invention, the double-layer three-dimensional yard of the automated container terminal is provided with a charging wall and a charging interface design for the internal container trucks, so that the internal container trucks can be charged while operating, and there is no need to set up special charging piles or battery swap stations in the operating area.

[0129] In order to more clearly understand the technical solution of the present invention, the following is a further description in combination with specific embodiments. The double-layer three-dimensional yard of the automated container terminal provided by the present invention is used to realize the collection and distribution of containers at the port.

[0130] Example 1.

[0131] Example 1 takes unloading containers from a ship to a storage yard and then transferring the containers out of the storage yard as an example to introduce an implementation mode of the present invention.

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

[0133] In the first stage, the ship-to-yard operation is performed: first, the inner container truck 5 travels to the external positioning base 122 of the quay crane connected to the quay crane 11, then the container on the container ship 10 is lifted by the lifting device of the quay crane 11 and unloaded onto the inner container truck 5, then the inner container truck 5 travels on the passage of the upper platform 1 to the bottom of a yard crane 4, the container is lifted from the inner container truck 5 by the lifting device 8 of the yard crane 4, and then lifted to the container storage area 7 of the lower platform 2 through the hollow lifting operation area 9;

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

[0135] Example 2.

[0136] Example 2 takes the container collection at the port and loading and shipping, container unloading and port clearance operations as examples to introduce the implementation mode of the present invention.

[0137] In embodiment 2, the present invention includes a second working mode: a working mode in which the container is unloaded to the yard by an external container truck and then loaded onto the ship from the yard, and the working mode includes the following operations:

[0138] In the first stage, the operation from the outside to the yard is performed: the external container truck 6 enters the yard at the front of the wharf and drives to the container storage area 7 on the lower platform 2. The lifting device 8 of the yard crane 4 passes through the hollow lifting operation area 9, and then the lifting device 8 of the yard crane 4 lifts the container on the external container truck 6 to the container storage area 7;

[0139] In the second stage, the operation from the yard to the ship is performed: first, the inner container truck 5 travels on the upper platform 1 to the bottom of a yard crane 4, and the lifting device 8 of the yard crane 4 lifts the container in the container storage area 7 onto the inner container truck 5 through the hollow lifting operation area 9. Then, the inner container truck 5 travels to the external positioning base 122 of the quay crane connected to the quay crane 11, and is lifted to the container ship 10 by the lifting device of the quay crane 11.

[0140] It can be seen from the above embodiments that, in the present invention, the double-layer structure design of the storage yard changes the operation organization of the quay crane 11, the yard crane 4, the inner container truck 5 and the outer container truck 6.

[0141] Compared with the prior art, by applying the present invention, for the quay crane 11, the operation path for lifting and unloading containers at the shore end 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: from the quay crane to the lower platform 2 on the ground, since the upper platform 1 serving as the container unloading destination is above the lower platform 2, the operation path of the quay crane 11 (for example, the lifting equipment moving path in the vertical direction) is shortened.

[0142] By applying the present invention, for the yard crane 4, since the inner container truck 5 and the outer container truck 6 can enter the yard area (that is, the inner container truck 5 can enter the area beside the lifting operation area 9 above the container storage area 7, and the outer container truck 6 can enter the area beside the container storage area 7 of the lower platform 2), the yard crane 4 replaces the transportation task along its supporting track (for the track, the original prior art is arranged on the lower platform 2 on the ground, and the present invention is arranged on the upper platform 1), so the displacement of the yard crane 4 along its supporting 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 container truck 5, and can also complete the loading and unloading of containers on the outer container truck 6 and the unloading of containers in the container storage area 7 through the hollow lifting operation area 9.

[0143] By applying the present invention, the inner container truck 5 can enter the yard area of ​​the upper platform 1 (i.e., the area beside the lifting operation area 9 above the container storage area 7 of the lower platform 2) without meeting the outer container truck 6, thereby improving the operation time efficiency. The outer container truck 6 can enter the yard area on the lower platform 2 (i.e., the area beside the container storage area 7) without meeting the inner container truck 5, thereby improving the operation time efficiency.

[0144] Compared with the prior art, the double-layer three-dimensional stacking yard of the automated container terminal provided by the present invention has the following beneficial effects:

[0145] 1. The double-layer three-dimensional yard of the automated container terminal provided by the present invention 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 container yard reduces the operation 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 storage yard of the present invention reduces the repeated paths of lifting and lowering containers, and reduces the energy consumption of storage yard operations;

[0148] 4. There is no double-layered container yard at home and abroad. The present invention fills the gap in the three-dimensional layout of the automated container yard;

[0149] 5. The external positioning base of the quay crane and yard crane designed in the present invention greatly reduces the positioning time between the quay crane, yard crane and container truck;

[0150] 6. The internal container truck charging wall and charging interface designed by the present invention enable the internal container truck to charge while operating;

[0151] 7. The present invention has a reasonable structural design and can be assembled using mostly prefabricated modules, so it is convenient to upgrade and renovate existing docks.

[0152] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
