Description

Technical Field

[0001] The invention belongs to the technical field of port logistics equipment, and in particular relates to a straddle-type zero-tip container terminal and an operation method thereof. Background Art

[0002] Automated container terminals have become popular all over the world. However, automated container terminals still retain a lot of traces of traditional container terminals. For example, unmanned container trucks or AGVs for flat transportation are used to replace manned container trucks, unmanned large rail cranes are used to replace manned large rail cranes in container yards, and the container stacking process in the yard is still "stacking 5 over 6", etc. The so-called automation only realizes unmanned operation, and there are almost no major changes in the operation process route and equipment form. This has led to improved efficiency and reduced manpower in automated container terminals. However, there are still problems such as bridge cranes and AGVs waiting for each other, AGVs avoiding each other, long-distance "full-yard" flat transportation, unreasonable disassembly and assembly process routes, high energy consumption for lifting and handling, low efficiency of loading and unloading ship collection and distribution, high container tipping rate in the yard, frequent interference between loading and unloading ships and collection and distribution, and large yard area.

[0003] As the name suggests, a digital container terminal is a container terminal that adds digital technology and artificial intelligence technology to the entire process of loading and unloading ships. However, if the operating process similar to that of traditional container terminals is still used, the purpose of a truly digital container terminal cannot be achieved. Summary of the invention

[0004] The present invention proposes a straddle-type zero-tipover container terminal and an operating method thereof, which aims to solve the problems existing in existing automated container terminals, such as bridge crane AGVs waiting for each other, AGVs avoiding each other, long-distance "full-yard" plane transportation, unreasonable disassembly and assembly lock process routes, high energy consumption in lifting and handling, low efficiency of loading and unloading ship collection and distribution, high container tipping rate in the yard, many interferences between loading and unloading ships and collection and distribution, and large area of ​​container yard. In view of the drawbacks of traditional container terminals, based on the essential requirements of digital technology of "more precise, smoother, more efficient, greener and lower cost", the equipment, layout and operation process of the container terminal are transformed into a whole process according to the requirements of digitalization, so that every container can "move freely", meet the requirements of digitalization for hardware, completely subvert the operation process of the existing container terminals, and truly meet the requirements of "smart port, green port".

[0005] The present invention is implemented by the following technical solutions: A straddle-type zero-tip container terminal is proposed, in which quay cranes, straddle-type loading and unloading lines and three-dimensional storage yards are arranged in sequence from the sea side to the land side. The straddle carrier loading and unloading line is laid out along the wharf shoreline under the land side bridge body of the quay crane; The three-dimensional yard is composed of a multi-layer structure, and each layer of the yard stores a layer of containers; a non-powered rail flat car conveying system is arranged at the bottom of each layer of the yard; the non-powered rail flat car conveying system is composed of a non-powered rail flat car and its driving mechanism; Multiple lifting mechanisms for transporting containers in and out of the three-dimensional yard are arranged on both the sea and land sides of the three-dimensional yard; cross-transportation lines are arranged around the lifting mechanisms on the sea side of the three-dimensional yard; and several container truck parking spaces, container interactive platforms and truss-type loading and unloading mechanisms are arranged on the land side of the three-dimensional yard; Several straddle carriers transfer containers between the straddle carrier loading and unloading line under the quay crane and the straddle carrier delivery line on the sea side of the three-dimensional yard.

[0006] Based on the straddle-type zero-tip container terminal proposed in the present invention, during the unloading operation, after the quay crane grabs the container from the cabin, the container is placed on the container drop point of the straddle-carry unloading line. The straddle carrier crosses the container drop point of the unloading line to grab the container and transfer it to the unpowered rail flat car on the sea side of the three-dimensional yard. The container is transported from the straddle-carrying line to the lifting mechanism with the unpowered rail flat car, and is transported to the target layer of the three-dimensional yard by the lifting mechanism, and is transported to the target position through the container longitudinal conveying channel of the target layer and the target storage transverse conveying line. During the loading operation, the container to be loaded in the three-dimensional yard is transported to the sea side lifting mechanism based on the operation of the unpowered rail flat car system, and is transported to the straddle-carrying line through the sea side lifting mechanism. The straddle carrier grabs the container from the unpowered rail flat car on the straddle-carrying line and transfers it to the straddle-carrying loading line under the quay crane, and drops the container on the container drop point of the straddle-carrying loading line. The quay crane trolley directly grabs the container from the container drop point of the straddle-carrying loading line.

[0007] A straddle-type zero-tip container terminal operation method is proposed, which is applied to the straddle-type zero-tip container terminal as described above, comprising: Ship unloading operations, including: The quay crane grabs the container from the cabin and places it on the container drop point of the straddle carrier unloading line; The straddle carrier crosses the unloading line and grabs the container at the container drop point; The straddle carrier transfers the containers alternately to the unpowered rail flat cars on the left and right longitudinal conveyor lines of the sea side straddle transport line of the three-dimensional yard; The container is transported with the unpowered rail flat car to the lock disassembly and assembly workstation at the intersection of the longitudinal conveyor line and the transverse conveyor line across the transport line, and stops. After the lock disassembly operation is completed, it is transported to the lifting mechanism via the transverse conveyor line; The lifting mechanism delivers the unpowered rail flat car carrying the container to the target layer, and then transports it to the target location through the container longitudinal conveying channel of the target layer and the target storage transverse conveying line; Ship loading operations, including: The containers to be loaded in the three-dimensional yard are transported to the sea-side lifting mechanism by the unpowered rail flat cars; The sea-side lifting mechanism transports the unpowered rail flat car loaded with containers to the horizontal conveyor line of the straddle carrier. The unpowered rail flat car driving system transports the unpowered rail flat car loaded with containers to the disassembly and installation workstation at the intersection of the horizontal conveyor line and the longitudinal conveyor line and stops. After the locking operation is completed, it is transported to the straddle carrier interaction area via the longitudinal conveyor line. The straddle carriers alternately grab containers from the unpowered rail flat cars on the left and right longitudinal conveyor lines of the straddle carrier conveyor line, and transfer them to the container drop-off point of the straddle carrier loading line under the quay crane. The quay crane grabs the container from the drop point of the straddle carrier loading line and transfers it to the target location in the ship's hold; Simultaneous unloading and loading operations include: The left longitudinal conveyor line of the sea side cross-transport line of the three-dimensional yard transports the unloaded container with the unpowered rail flat car to the disassembly and installation lock workstation at the intersection of the left longitudinal conveyor line and the transverse conveyor line, and stops to carry out the disassembly and installation lock operation and wait for the lifting mechanism; The sea-side lifting mechanism of the three-dimensional yard transports the shipping container from the target layer of loading and unloading ships to the horizontal conveyor line of the straddle conveyor line along with the non-powered rail flat car, and stops at the disassembly and locking workstation at the intersection of the horizontal conveyor line and the right longitudinal conveyor line. After the locking operation is implemented, the shipping container is transported to the straddle carrier interaction area of ​​the right longitudinal conveyor line along with the non-powered rail flat car; The straddle carriers on both sides of the lifting mechanism carry out unloading and loading operations alternately in the two longitudinal conveyor lines on the left and right sides of the straddle carriers. The straddle carrier transfers the unloaded container from the straddle transport unloading line under the quay crane to the sea side of the three-dimensional storage yard. After crossing over the empty non-powered rail flat car on the longitudinal conveying line on the left side of the straddle transport line, the straddle carrier drops the unloaded container on the non-powered rail flat car. The straddle carrier then changes lanes and crosses over the heavy-loaded non-powered rail flat car on the longitudinal conveying line on the right side of the straddle transport line, lifts the loaded container and drives to the straddle transport loading line under the quay crane. The straddle carrier transfers the shipping container transferred from the straddle transport delivery line of the three-dimensional yard to the straddle loading line under the quay crane. After the straddle carrier drops the shipping container on the container drop point of the straddle loading line, the straddle carrier changes lanes from the straddle loading line to the straddle unloading line to wait for the transfer of the next unloading container; After the quay crane drops the unloading container onto the container drop point of the straddle carrier unloading line, the trolley crane will then move to the space above the loading container position of the straddle carrier loading line, grab the container, lift it and transport it to the ship for loading; Port collection operations, including: The container trucks are waiting to be unloaded at the container truck parking space on the land side of the three-dimensional storage yard; The truss-type loading and unloading mechanism lifts the container from the container truck and hoists it onto the empty non-powered rail flat car on the high-level container exchange platform corresponding to the lifting mechanism; the containers whose target location is on the first and second floor yards of the container port are hoisted onto the empty non-powered rail flat cars on the first and second floor container exchange platforms; The container is transported to the target location by the non-powered rail flat car and the lifting mechanism through the non-powered rail flat car conveying system of the target layer in the three-dimensional yard; or it is directly transported from the non-powered rail flat car conveying line of the first- and second-layer container interactive platform to the non-powered rail flat car conveying system in the first- and second-layer yard and transported to the target location; Port dredging operations include: The container is transported to the land side of the three-dimensional yard by the non-powered rail flat car conveying system in the three-dimensional yard with the non-powered rail flat car; Containers in the third and above layers of the three-dimensional storage yard are transported to the lifting mechanism by the unpowered rail flat car, and then transported to the high-level container interactive platform corresponding to the lifting mechanism through the lifting mechanism; The containers on the first and second floors of the three-dimensional yard are directly transported to the container exchange platforms on the first and second floors by unpowered rail flat cars; The truss-type loading and unloading mechanism lifts the container onto the container truck waiting at the container truck parking space.

[0008] Compared with the prior art, the advantages and positive effects of the present invention are as follows: the straddle-type zero-tipover container terminal proposed in the present invention solves the two major bottleneck problems of insufficient loading and unloading equipment resources and container tipping in traditional container terminal yards. These two major bottleneck problems are also the long-standing "intestinal obstruction" problems of traditional container terminal yards, thereby fundamentally subverting a series of traditional long-distance "full yard" flat transportation and "piling 5 through 6" and other operating processes. Compared with the existing container terminal layout, only the quay crane is retained, and the traditional long-distance shore transport operation lanes at the front of the terminal are no longer arranged. Instead, the target berth ship corresponds to the target berth yard with a short-distance vertical shore transport operation lane, which effectively shortens the horizontal transportation distance of containers from the terminal shoreline to the container yard; the horizontal transportation on the sea side is replaced by straddle carriers instead of the existing AGV or unmanned container trucks, and the containers are transferred between the straddle loading and unloading line under the quay crane and the sea-side straddle transport line of the three-dimensional yard corresponding to the quay crane; the existing AGV or unmanned container truck and the super-large yard rail crane exchange container method is replaced by straddle carriers and the three-dimensional yard cross-transport line and small lifting mechanism exchange containers; the sea-side yard multiple lifting mechanisms and several one-story yard straight-in and straight-out container handling equipment resources have replaced the existing limited number of single super-large and bulky rail cranes, and the sea-side loading and unloading ship handling equipment resources are rich, The sea-side operation efficiency is greatly improved; the container handling and hoisting equipment resources of the land-side yard with multiple lifting mechanisms, several first- and second-story yards with direct entry and exit, and multiple truss loaders have greatly improved the efficiency of port collection and clearance on the land side; the independent operation of the sea-side ship loading and unloading equipment resources and the land-side collection and distribution equipment resources has changed the disadvantage of the existing sea-side ship loading and unloading equipment resources and the land-side collection and distribution equipment resources interfering with each other; the multi-layered three-dimensional yard has replaced the traditional "5-over-6" operation mode of the container yard, and each layer is an independent container yard, which provides convenience for the pre-ship loading operation process; the three-dimensional yard, the sea-side cross-transport line of the yard, and the disassembly and assembly lock workstation on the cross-transport line, the container cross-transport loading and unloading line under the quay crane, the unmanned straddle carrier and the quay crane constitute a new mode of simultaneous unloading and loading operations; the emergence of the three-dimensional yard has inadvertently created a huge rooftop resource for photovoltaic power generation.

[0009] The above positive changes are a complete subversion of the traditional container terminal operation process, including the existing automated container terminals. The specific quantitative indicators are as follows: The efficiency of loading and unloading ships on the sea side is about 30% higher than that of automated terminals and more than 50% higher than that of traditional terminals; The efficiency of landside collection and distribution is more than 100% higher than that of automated terminals and more than 150% higher than that of traditional terminals; The container tipping rate in the yard has been reduced from about 60% in the traditional "5-over-6" yard to "zero"; The energy consumption per container is reduced by more than 70% compared with automated terminals and more than 50% compared with traditional terminals; Berth turnover rate is more than 20% higher than that of automated terminals; The land occupied is reduced by more than 50% compared with automated terminals and traditional terminals; The level of digitalization, intelligence and greening is a qualitative improvement over automated terminals; The investment cost is about 20% higher than that of an automated terminal, but the cost-effectiveness is extremely high.

[0010] Combining the above qualitative and quantitative analysis, it can be seen that the present invention not only revolutionizes the traditional container terminal operation process route, but also brings about great social and corporate benefits. It is a typical representative of the new quality productivity of world-class ocean ports.

[0011] Specifically, the straddle carrier loading and unloading line under the landside bridge arm of the quay crane at the front of the wharf is paved with multiple pairs of channel steels or concave materials, and is used to exchange containers with the quay crane and straddle carrier. It can be divided into straddle carrier loading line and straddle carrier unloading line, which are arranged at intervals.

[0012] Specifically, the straddle conveyor line on the sea side of the three-dimensional yard is H-shaped, including two longitudinal conveyor lines arranged on both sides of the lifting shaft of the lifting mechanism and a transverse conveyor line arranged at the entrance and exit of the lifting mechanism. One end of the two longitudinal conveyor lines is connected to the first floor of the three-dimensional yard, and the other end exchanges containers with the straddle carrier. The transverse conveyor line is vertically connected to the conveyor line at the bottom of the lifting mechanism. When loading, the containers in the yard can be transported to the sea side of the yard via the non-powered rail flat car conveying system. When it is on the first floor of the yard, it can be directly transported to the longitudinal conveyor line of the straddle conveyor line. When it is on the second floor or above, it can be transported to the lifting mechanism, and then transported by the lifting mechanism to the transverse conveyor line of the straddle conveyor line, and then transported from the transverse conveyor line to the longitudinal conveyor line of the straddle conveyor line. The straddle carrier crosses the non-powered rail flat car on the longitudinal conveyor line to grab the container. The process is the opposite when unloading.

[0013] In an embodiment of the present invention, a lock disassembly and assembly workstation is arranged below the intersection of the longitudinal conveyor line and the transverse conveyor line across the transport conveyor line, which is used for disassembling the lock during unloading operations and installing the lock during loading operations. A robot or manual lock disassembly and assembly is arranged at the lock disassembly and assembly workstation.

[0014] In an embodiment of the present invention, the three-dimensional yard is a multi-layer yard composed of multi-layer steel structures or other structures. The three-dimensional yard of each berth is composed of multiple three-dimensional sub-yards, and each three-dimensional sub-yard is composed of multiple unit yards. Each unit yard is equipped with a sea-side lifting mechanism and a land-side lifting mechanism on the sea side and the land side respectively. A container longitudinal conveying channel is arranged between the sea-side lifting mechanism and the land-side lifting mechanism. A plurality of storage transverse conveying lines that can store multiple containers are arranged on both sides of the container longitudinal conveying channel, thereby forming a non-shaped conveying and storage space that can convey multiple containers longitudinally and store multiple containers transversely on each layer of a unit yard. Through the conveying of the container longitudinal conveying channel and the lifting mechanism, the containers can quickly enter and exit the three-dimensional yard.

[0015] In an embodiment of the present invention, an unpowered rail flat car conveyor line is arranged at the bottom of the lifting mechanism. The unpowered rail flat car conveyor line is connected with the longitudinal conveying channels of containers in each stack layer in the three-dimensional yard and the four-way conveying power units on the land-side container exchange platform conveyor line and the transverse conveying line in the sea-side container cross-transport conveyor line as the lifting mechanism rises and falls, so as to facilitate the containers to enter and exit the three-dimensional yard.

[0016] In an embodiment of the present invention, a cold box storage yard is arranged in one or all layers of one or all sub-yards in a berth yard, and a power plugging and unplugging robot is arranged under the storage transverse conveying line of the cold box storage yard, which can automatically plug in or unplug the cold box power supply.

[0017] In the embodiment of the present invention, a four-way transport power unit is arranged on the longitudinal transport channel of containers inside the three-dimensional yard; a four-way transport power unit is arranged at the longitudinal and transverse reversing position of the first layer on the sea side and the second layer on the land side of the three-dimensional yard where containers directly enter and exit the yard; a four-way transport power unit is arranged at the intersection of the longitudinal conveying line and the transverse conveying line across the transport line; a four-way transport power unit is arranged at the position where the transverse conveying line across the transport line and the conveying line at the bottom of the lifting mechanism are connected. The four-way transport power unit is used to realize the reversing transport of the unpowered rail flat car on the conveying line, which is not limited to the present invention. The applicant has proposed protection for the specific implementation of the four-way transport power unit in another patent application.

[0018] In an embodiment of the present invention, friction drive technology is used on each conveyor line and cross-transport conveyor line in the three-dimensional yard, power rail wheels and driven rail wheels are evenly arranged on the conveyor line body, a criss-cross track is arranged on the back of the unpowered rail flat car, and a gap is left at the vertical intersection of the criss-cross track for the rail wheel wings to pass through, so as to facilitate the rail wheels to pass through the track when the unpowered rail flat car travels longitudinally or transversely.

[0019] In the embodiment of the present invention, each unit yard on the land side of the three-dimensional yard is equipped with two or more truck parking spaces and two or more container interaction platforms; the container interaction platforms include a first-layer container interaction platform directly connected to the first layer of the three-dimensional yard and a second-layer container interaction platform directly connected to the second layer of the three-dimensional yard; a high-level container interaction platform is connected to the third layer and above of the three-dimensional yard through a lifting mechanism; the truck parking spaces are located on both sides of the high-level container interaction platform connected to the lifting mechanism. When the container is cleared from the port, the container is transported to the land side of the yard through the non-powered rail flat car conveying system, and then transported to the lifting mechanism, and then transported to the high-level container interaction platform corresponding to the lifting mechanism through the lifting mechanism, and then hoisted by the container loading and unloading machine arranged on the truss to the truck waiting at the truck parking space; or the first and second-layer containers of the three-dimensional yard are directly transported to the first and second-layer container interaction platforms, and then hoisted by the container loading and unloading machine arranged on the truss to the truck waiting at the truck parking space. The container port operation is the opposite of the process route of the port clearance operation.

[0020] Considering that the container terminal loads and unloads a small number of 45-foot containers, two units of 45-foot container yards are arranged in this plan.

[0028] like Figures 1 to 5 As shown, the straddle-type zero-tip container terminal in this embodiment is arranged with a quay crane 1, a straddle-type loading and unloading line 2 and a three-dimensional yard 3 in sequence from the sea side to the land side. The straddle-type loading and unloading line 2 is composed of a straddle-type unloading line 21 / 23 and a straddle-type loading line 22 / 24 arranged at intervals, which is arranged along the wharf shoreline below the land side bridge arm of the quay crane 1 and is perpendicular to the land side bridge arm.

[0029] The three-dimensional yard 3 is composed of a multi-layer steel frame structure, each layer of the yard only stacks one layer of containers, and a non-powered rail flat car conveying system is arranged at the bottom of each layer of the yard, and the non-powered rail flat car conveying system is composed of a non-powered rail flat car 4 and its driving mechanism. The non-powered rail flat car 4 is driven by its driving mechanism to enter and exit the yard with heavy load or no load.

[0030] A plurality of lifting mechanisms 31 for transporting containers in and out of the yard are arranged on both the sea side and the land side of the three-dimensional yard 3, a cross-transportation delivery line 5 is arranged around the lifting shaft of the lifting mechanism 31 on the sea side of the three-dimensional yard 3, and a container truck parking space 61, a first-layer container interaction platform 62, a second-layer container interaction platform 63, a high-layer container interaction platform 64 and a truss-type loading and unloading mechanism 7 are arranged on the land side of the three-dimensional yard 3. The truss-type loading and unloading mechanism is composed of a truss 71 and a container loader 72. The truss 71 covers the land side of the three-dimensional yard 3, and the container truck parking space 61, the first-layer container interaction platform 62, the second-layer container interaction platform 63, and the high-layer container interaction platform 64 are all arranged under the truss 71, so that the container loader 72 can interact with any of the interaction platforms and the container truck to exchange containers.

[0031] The straddle carrier conveyor line 5 is H-shaped, and its longitudinal conveyor line 51 is distributed on both sides of the lifting shaft of the lifting mechanism 31. One end is connected to the first floor of the three-dimensional yard 3, and the other end interacts with the straddle carrier. Its transverse conveyor line 52 is vertically connected to the bottom conveyor line of the lifting mechanism 31.

[0032] In each layer of the three-dimensional yard 3, a container longitudinal conveying channel is arranged between the lifting mechanism on the sea side and the lifting mechanism on the land side, and a number of container transverse conveying lines that can store multiple containers are arranged on both sides of the container longitudinal conveying channel. The containers are stored on the container transverse conveying lines. When they need to enter or exit the yard, they are first transported to the container longitudinal conveying channel, and then the container longitudinal conveying channel is connected with the lifting mechanism to realize the container entering and exiting the yard.

[0033] The straddle carrier 8 transfers containers back and forth between the straddle carrier loading and unloading line 2 and the straddle carrier conveying line 5. It can straddle the straddle carrier loading and unloading line 2 and the straddle carrier conveying line 5 and exchange containers with the unpowered rail flat cars 4 on the straddle carrier loading and unloading line 2 and the straddle carrier conveying line 5.

[0034] A disassembly and assembly lock workstation 9 is arranged below the intersection of the longitudinal conveying line 51 and the transverse conveying line 52 of the straddle transport line 5. When loading a container, the container is locked at the disassembly and assembly lock workstation 9 after leaving the yard with the non-powered rail flat car 4, and then transported to the longitudinal conveying line 51 to interact with the straddle carrier 8. When unloading a container, the straddle carrier 8 places the container on the non-powered rail flat car of the longitudinal conveying line 51, and after being unlocked at the disassembly and assembly lock workstation 9, the container directly enters the yard via the longitudinal conveying line 51 or turns to the transverse conveying line 52, and is transported to the target layer yard via the lifting mechanism 31.

[0035] The three-dimensional yard 3 is provided with a cold box storage yard, a plug-in electric manipulator 34 is provided at the bottom of the container transverse conveying line of the cold box yard, and power conversion sockets 41 and 42 are provided on the end face and the back face of the unpowered rail flat car 4.

[0036] A non-powered rail flat car conveyor line is arranged at the bottom of the lifting mechanism 31, which is connected with the longitudinal conveying channels of each stack container layer of the three-dimensional yard 3 as the lifting mechanism 31 is raised and lowered; a four-way conveying power unit 10 is arranged on the transverse conveying line 52 of the cross-transport conveyor line 5, which is connected with the non-powered rail flat car conveyor line at the bottom of the lifting mechanism 31, forming a passage for containers to enter and exit the yard.

[0037] Four-way transport power units 10 are arranged on the longitudinal container transport channel 31 inside the three-dimensional yard 3, at the intersection of the longitudinal conveying line 51 and the transverse conveying line 52 of the cross-transport conveying line 5, at the position where the transverse conveying line 52 of the cross-transport conveying line 5 connects with the bottom conveying line of the lifting mechanism 31, and inside the first and second floor entrances and exits of the sea-side yard and the first and second floors of the land-side yard, so that the containers can freely turn vertically and horizontally at these node positions. For example, the four-way transport power unit 10 is composed of a longitudinal wheel set 101 and its driving mechanism (consisting of a longitudinal wheel set base 1021, a longitudinal drive motor 1022, a lifting device 1023, a lifting motor 1024, etc.) and a transverse wheel set 103 and its driving mechanism (consisting of a transverse wheel set base 1041, a transverse drive motor 1042, a lifting device 1043, a lifting motor 1044, etc.). Through the lifting action of the lifting motor 1024 / 1044 and the lifting device 1023 / 1043, the longitudinal wheel set 101 and the transverse wheel set 103 are switched up and down to respectively realize the longitudinal drive or transverse drive of the unpowered rail flat car 4. The specific working principle is the protection content of another invention application of the applicant, and is not limited to the present invention. The mechanisms that can implement longitudinal operation drive and transverse operation drive of the unpowered rail flat car 4 are all included in the four-way transport power unit referred to in the present invention.

[0038] The following is a detailed description of the operation process of the straddle-type zero-tip container terminal provided above in the present invention.

[0039] Since the present invention proposes a straddle-type zero-tip container terminal layout, and in particular proposes a layout design within a three-dimensional yard, each container in the yard is stored on a non-powered rail flat car, so that each container can be moved. According to the terminal layout proposed by the present invention, its operation process can completely overturn the existing operation process of the traditional container yard "stack 5 over 6" and long-distance alongshore transportation, long-distance vertical shore transportation, big horse pulling small carts, and heavy trucks coming and empty trucks returning, so as to achieve the requirements of "more accurate, more smooth, more efficient, more green, and lower cost".

[0040] Assume that a berth is equipped with 4 8-layer sub-yards, each of which has 3 unit yards, and each unit yard has 36 TEUs arranged longitudinally from the sea side to the land side. Each unit yard has 3 TEUs of container storage transverse conveyor lines arranged transversely on both sides of the container longitudinal conveying channel. The total container space of this berth yard is 20736 TEUs. On the sea side, there are 12 lifting mechanisms that can transport 2-8 layer yard containers, and each layer of the 1st layer yard has 24 entrances and exits directly connected to the H-type straddle carrier conveyor line; on the land side, there are 12 lifting mechanisms that can transport 3-8 layer yard containers, and each layer of the 1st-2nd layer yard has 24 entrances and exits connected to the container exchange platform. The 1st and 2nd floors are used as 20-foot standard container yards, and the 3rd layer yard is arranged with a considerable number of cold box positions, and the compressor faces the land side.

[0041] According to the above assumptions, 20-foot standard containers (20-foot containers are standard containers TEU) are stacked on the 1st and 2nd floors, that is, the container longitudinal conveying channel 32 from the sea side to the land side is composed of 36 four-way conveying power units 10 that are compatible with the size of standard containers arranged longitudinally, and the storage transverse conveying lines 33 on both sides of the container longitudinal conveying channel 32 are composed of 36 storage transverse conveying lines on the left and 36 storage transverse conveying lines on the right, and each storage transverse conveying line 33 arranges 3 standard container TEUs. Here, the coordinates of each container position are set: with the sea side as the starting point and the land side as the end point, with the container longitudinal conveying channel 32 as the center, the storage transverse conveying lines 33 are numbered as row 1, row 2, row 3... row 36, that is, row 1 storage transverse conveying line, row 2 storage transverse conveying line, row 3 storage transverse conveying line... row 36 storage transverse conveying line, the specific position coordinates are divided into left storage transverse conveying line and right storage conveying line, the position coordinates are expressed as row 1 left 1 left 2 left 3 and row 1 right 1 right 2 right 3... row 36 left 1 left 2 left 3 and row 36 right 1 right 2 right 3, row 1 in row 1 left 2 represents the first row of storage transverse conveying line, left 2 represents the second position of the left storage transverse conveying line, and so on.

[0042] Similarly, 40-foot containers (the size of two 20-foot containers) are stacked in 3 to 8 layers, that is, the container longitudinal conveying channel 32 from the sea side to the land side is composed of 36 four-way conveying power units 10 that are compatible with the standard container size and arranged longitudinally, and the storage transverse conveying lines 33 on both sides of the container longitudinal conveying channel 32 are composed of 18 storage transverse conveying lines on the left and 18 storage transverse conveying lines on the right, and each storage transverse conveying line 33 is arranged with 3 40-foot containers. Here, the coordinates of each 40-foot container position are set, with the sea side as the starting point, the land side as the end point, and the container longitudinal conveying channel 32 as the center. The storage transverse conveying lines 33 are numbered as row 1, row 2, row 3...18 rows, that is, row 1 storage transverse conveying line, row 2 storage transverse conveying line, row 3 storage transverse conveying line...18 rows storage transverse conveying line, the 40-foot container rail flat car is adapted with two four-way conveying power units 10 on the container longitudinal conveying channel 32, and the width of the 40-foot container storage transverse conveying line 33 is twice that of the 20-foot container storage transverse conveying line. The specific position coordinates are divided into the left storage transverse conveying line and the right storage conveying line, and the position coordinates are expressed as row 1 left 1 left 2 left 3 and row 1 right 1 right 2 right 3...18 rows left 1 left 2 left 3 and row 18 right 1 right 2 right 3, row 1 left 2 in which row 1 represents the first row of storage transverse conveying line, left 2 represents the second position of the left storage transverse conveying line, and so on.

[0043] Each three-dimensional sub-yard on the sea side of the three-dimensional yard 3 has three unit yards, and each unit yard is equipped with two straddle carriers 8. The straddle carriers 8 corresponding to the three unit yards of a three-dimensional sub-yard are No. 1, No. 2, No. 3, No. 4, and No. 5, No. 6, respectively, and No. 1, No. 2 correspond to unit yard 1, No. 3, No. 4 correspond to unit yard 2, and No. 5, No. 6 correspond to unit yard 3; each unit yard is equipped with a set of straddle transport conveyor lines 5, and the straddle transport conveyor lines 5 corresponding to a three-dimensional sub-yard are numbered 1-1, 1-2, 2-1, 2-2, 3-1, 3-2, respectively, and 1-1, 1-2 correspond to unit yard 1, 2-1, 2-2 correspond to unit yard 2, and 3-1, 3-2 correspond to unit yard 3.

[0044] Four parallel straddle-ship loading and unloading lines 2 with magnetic nail induction or sensor induction markings are arranged on the ground below the landside bridge arm of the quay crane 1, namely No. 1 straddle-ship unloading line 21, No. 2 straddle-ship loading line 22, No. 3 straddle-ship unloading line 23, and No. 4 straddle-ship loading line 24, and No. 1 and No. 2 are a group, and No. 3 and No. 4 are a group.

[0045] Since the three-dimensional yard 3 of the present invention has the characteristics of zero container tipping, cross-transport delivery line 5 on the sea side of the yard, disassembly and assembly lock workstation 9 on the cross-transport delivery line 5, the cross-transport loading and unloading line 2 directly laid on the ground below the land side bridge arm of the quay crane 1, the straddle carrier 8 accurately cross-transporting containers between the cross-transport loading and unloading line 2 and the cross-transport delivery line 5, and the rich resources of sea and land side loading and unloading and handling equipment and distributed operation, it has the characteristics of short-range interaction between ship berths and yard berths, and two-way interaction of handling equipment with containers. Especially for large ports with high berth utilization rate, each berth yard can arrange multiple ship loading and unloading operation plans in a layered operation mode according to the ship schedule. For example, when the three-dimensional yard is loading and unloading ships on the 5th floor, the 5th floor has completed the port collection operation before the container is loaded, and the 5th floor has reserved the number of unloading containers on the land side in advance, and the land side port collection and unloading transportation operations including the 5th floor are not affected at all.

[0046] Ship loading and unloading process: For example, if a ship berths at berth No. 2 to load and unload containers, it plans to unload 1,200 TEU containers (including 300 standard containers and 450 40-foot containers) and load 1,500 TEU containers (including 400 standard containers and 550 40-foot containers). The unloading and loading stowage diagram is sent to the container terminal company in advance, and the terminal company makes a pre-shipping plan accordingly. If the ship loading and unloading operations are arranged on the 5th floor and 1st and 2nd floors of the 4 three-dimensional sub-yards at berth No. 2, 550 40-foot containers are stored in the 5th floor yard, and the average number of 40-foot containers collected on the 5th floor of each unit yard of each three-dimensional sub-yard is about 45, and 400 standard containers are stored on the 1st and 2nd floors. On average, about 17 20-foot containers are collected on the 1st and 2nd floors of each unit yard (of course, the specific number of containers collected on each unit yard must be consistent with the stowage diagram provided by the shipping company); sufficient number of unloading container positions are reserved on the 5th floor and 1st and 2nd floors for unloading containers.

[0047] Specifically, according to the unloading and loading diagram, the 5 quay cranes 1 at berth No. 2 correspond to 4 three-dimensional sub-yards, of which the three-dimensional sub-yard No. 3 is equipped with 2 quay cranes 1 working side by side. The operation is generally unloading first and then loading. Based on the terminal layout provided by the present invention, because it is a new process zero-overturning three-dimensional container yard, it can support the simultaneous unloading and loading process, that is, the traditional process of unloading all the containers in one bay and then loading the loading containers in this bay is changed to unloading the unloading containers in one bay and one row first, and then the quay crane trolley crane carries the loading container into the row of containers that have just been unloaded. After the container is loaded into the row, the quay crane trolley crane performs unloading operations on the second row of containers unloaded. After the loading and unloading of the bay is completed, the quay crane 1 moves to the next bay to perform unloading and loading operations, and so on. The shoulder-to-shoulder operation mode is a superimposed process of single quay crane operation. It is just to adapt to the simultaneous operation of two quay cranes. The number of straddle carriers in a three-dimensional sub-yard is increased accordingly. Therefore, the present invention only describes the unloading and loading operations of a single quay crane corresponding to a three-dimensional sub-yard.

[0048] Specifically, the trolley crane and straddle carrier 8 on the land side of the quay crane exchange containers with the straddle carrier loading and unloading line 2 on the shore. When loading and unloading containers at a certain position of the ship, when unloading the first row first, two empty straddle carriers 8 are accurately parked in the waiting area of ​​No. 1 and No. 3 straddle carrier unloading lines 21 / 23 on the ground below the land side bridge arm of the quay crane. After the trolley crane on the land side of the quay crane lifts the container from the ship and drops it into the container drop point of No. 1 straddle carrier unloading line 21, the trolley crane on the land side of the quay crane returns to the air above the ship to continue the unloading and grabbing operation; the straddle carrier 8 No. 1 waiting at the straddle carrier unloading line 21 slowly and accurately crosses the container on the container drop point, grabs the container and lifts it to the left side 1-1 longitudinal conveying line 51 of the sea side straddle carrier conveying line 5 of the three-dimensional yard 1 unit yard. At this time, the straddle carrier 8 No. 5 enters 1 Straddle carrier 8 is a carrier that is mounted on the quayside crane and is used to transport containers from the ship to the waiting area of ​​straddle carrier unloading line 21; after the trolley crane on the land side of the quayside crane hoists the container from the ship and drops it into the container drop point of straddle carrier unloading line 3 23, the trolley crane on the land side of the quayside crane returns to the air above the ship to continue the unloading and container grabbing operation; straddle carrier 8 waiting at straddle carrier unloading line 3 23 slowly and accurately crosses the container on the container drop point, grabs the container and lifts it to longitudinal conveying line 2-1 on the left side of straddle carrier conveying line 5 on the sea side of unit yard 2 of the stereoscopic yard, at which time straddle carrier 2 enters the waiting area of ​​straddle carrier unloading line 3 23…; straddle carriers 8 No. 1, 2, 3, 4, 5, and 6 operate alternately with straddle carrier unloading line 1 21 and straddle carrier unloading line 3 23 respectively, and unload the container by exchanging containers with straddle carrier 8 at quayside crane 1, and the cycle continues until completion.

[0049] Specifically, the straddle carrier 8 exchanges containers with the straddle transport line 5 on the sea side of the three-dimensional storage yard 3. The straddle carrier No. 1 8 carries the unloaded container from the straddle transport unloading line 21 into the calibration area (such as a magnetic nail sensing area or a marking line point) of the longitudinal conveying line 51 on the left side 1-1 of the straddle transport line 5 on the sea side of the unit yard of the three-dimensional storage yard 1, and then slowly and accurately straddles the longitudinal conveying line 51 on the left side 1-1 of the straddle transport line 5, and drops the container onto the unpowered rail flat car 4 on the longitudinal conveying line 51 on the left side 1-1 of the straddle transport line 5.

[0050] Specifically, the sea side cross-transport conveyor line 5 and the disassembly and assembly lock workstation 9 interact with each other. The container that falls on the unpowered rail flat car 4, driven by the conveying system, enters the disassembly and assembly lock workstation 9 (equipped with a four-way conveying power unit 10) at the vertical intersection of the longitudinal conveyor line 51 and the transverse conveyor line 52 of the cross-transport conveyor line 5 with the unpowered rail flat car 4 and stops. After the disassembly and assembly lock workstation 9 completes the disassembly and assembly lock workstation 9 robot or manual disassembly, the 20-foot container continues to move straight into the first floor of the three-dimensional yard 3 with the unpowered rail flat car 4, and the 40-foot container completes the reversal with the unpowered rail flat car 4 under the action of the four-way conveying power unit 10 and waits for the lifting mechanism 31 on the transverse conveyor line 52.

[0051] Specifically, the plug-in and unplug-out operation of cold box loading and unloading under the layout of the present invention is carried out as follows: in the three-dimensional yard 3, the cold box yard is centrally arranged, such as 4 three-dimensional sub-yards in a berth, and the 3rd floor of the No. 2 three-dimensional sub-yard is used as the cold box storage area. A plug-in and unplug-out electric manipulator 34 is arranged under each cold box position in the cold box storage area, and each unpowered rail flat car 4 is provided with power conversion sockets 41 and 42 on the end and back. When the unloaded cold box passes through the sea side of the three-dimensional yard 3 and crosses the transport conveyor line 5 to the interactive waiting area with the lifting mechanism 31, the staff will insert the power plug on the cold box into the power conversion socket 41 on the end of the unpowered rail flat car 4. When the unloaded cold box enters the designated position of the refrigerated storage area on the 3rd floor of the three-dimensional yard, the plug-in and unplug-out electric manipulator 34 at the bottom of the storage horizontal conveyor line will insert the power plug into the power conversion socket 42 on the back of the unpowered rail flat car 4. The cold box loading operation process is the opposite of the unloading operation.

[0052] Specifically, the sea-side cross-transport line 5 and the sea-side lifting mechanism 31 of the three-dimensional storage yard 3 exchange containers. After the lifting mechanism 31 of a unit storage yard descends to one layer, an empty unpowered rail flat car 4 drives out of the lifting mechanism 31 and enters the four-way conveying power unit 10 corresponding to the horizontal conveying line 52. After reversing, the empty unpowered rail flat car 4 drives to the 1-2 longitudinal conveying line 51 on the right side of the cross-transport line 5 to wait for the unloading container of the No. 2 straddle carrier 8; the heavy-loaded unpowered rail flat car 4 waiting at the intersection of the 1-1 longitudinal conveying line 51 and the horizontal conveying line 52 on the left side of the cross-transport line 5 is immediately transported to the four-way conveying power unit 10 corresponding to the lifting mechanism 31 for reversing. After the reversing is completed, the heavy-loaded unpowered rail flat car 4 drives into the lifting mechanism 31, and the lifting mechanism 31 brings the heavy-loaded unpowered rail flat car 4 to the 5-layer storage yard. According to the above actions, straddle carriers 8 No. 3, No. 4, No. 5 and No. 6 alternately transfer containers with the longitudinal conveying lines 51 on the left and right of the straddle transport line 5 of the second unit yard and the longitudinal conveying lines 51 on the left and right of the straddle transport line 5 of the third unit yard, respectively, until the unloading operation is completed.

[0053] Specifically, the loading operation and unloading operation processes are exactly the opposite, so they will not be elaborated.

[0054] Specifically, the unloading operation is carried out simultaneously with the loading operation. When the last container in the first row on the loading and unloading bay is unloaded by the quay crane trolley and falls onto the straddle carrier unloading line 21 or 23, the quay crane trolley immediately moves to the loading container on the container drop point of another straddle carrier loading line 22 or 24 to grab the container and load it. When the unloading and loading synchronization operation begins, the drop point of the No. 1 and No. 3 straddle carrier unloading lines 21 or 23 is empty, and there are straddle carriers 8 waiting in the waiting area of ​​the No. 1 and No. 3 straddle carrier unloading lines 21 / 23; there are containers ready to be loaded at the drop point of the No. 2 and No. 4 straddle carrier loading lines 22 / 24, and there are no straddle carriers waiting in the waiting area of ​​the No. 2 and No. 4 straddle carrier loading lines 22 / 24.

[0055] Specifically, after the trolley crane of the landside arm of the quay crane 1 drops the last container of the current unloading queue of the ship into the container drop point of No. 1 (or No. 3) straddle carrier unloading line 21 (or 23), the trolley crane of the landside quay crane runs to the loading container above the container drop point of No. 2 (or No. 4) straddle carrier loading line 22 (or 24) to grab the container and load it on board; the straddle carrier 8 No. 1 in the waiting area of ​​No. 1 straddle carrier unloading line 21 slowly and accurately crosses the unloading container on the container drop point and lifts it to the longitudinal conveying line 51 on the left / right side of the straddle carrier conveying line 5 of the first unit yard on the sea side of the stereoscopic yard 3; the straddle carrier 8 No. 5 drives the loaded container from the longitudinal conveying line 51 on the left / right side of the straddle carrier conveying line 5 of the third unit yard into the container drop point of No. 2 straddle carrier loading line 22 and drops the loaded container, then the straddle carrier 8 No. 5 changes lanes It enters the waiting area of ​​No. 1 straddle carrier unloading line 21 to wait for the next unloading container; at this time, the quay crane trolley crane lifts the first loading container to the first row of the ship that has just been unloaded and drops it into the storage space, then the quay crane trolley crane moves to the second row of unloading containers to grab the container and lift it to the drop point of No. 3 straddle carrier unloading line 23 to drop the unloading container, then the quay crane trolley crane moves to the drop point of No. 4 straddle carrier loading line 24 to grab the container and lift it to the ship for loading; No. 3 straddle carrier 8 in the waiting area of ​​No. 3 straddle carrier unloading line 23 slowly and accurately crosses the unloading container on the drop point and lifts it to the longitudinal conveying line 51 on the left / right side of the straddle carrier conveying line 5 of the second unit yard; No. 2 straddle carrier 8 is driven from the longitudinal conveying line 51 on the left / right side of the straddle carrier conveying line 5 of the first unit yard After entering the No. 4 straddle carrier loading line 24 with loaded containers and dropping the containers, the No. 2 straddle carrier 8 changes lanes to the No. 3 straddle carrier unloading line 23 to wait for the next unloading container; the quay crane trolley crane grabs the container from the No. 4 straddle carrier loading line 24 dropping point and runs to the top of the first row of the ship that has just been unloaded. After dropping the loaded container into the first row of storage positions, the quay crane trolley crane moves to the top of the second row of unloading containers to grab the container. The second row of unloading containers runs with the quay crane trolley crane to the No. 1 straddle carrier unloading line 21 dropping point and drops the container. The quay crane trolley crane runs to the No. 2 straddle carrier loading line 22 dropping point and grabs the loaded container; the No. 5 straddle carrier 8 in the waiting area of ​​the No. 1 straddle carrier unloading line 21 slowly and accurately crosses the dropping point to unload the container, then lifts it and drives to the left side of the straddle carrier delivery line 5 of the third unit yard / The longitudinal conveyor line 51 on the right side; No. 4 straddle carrier 8 drives the loaded container from the longitudinal conveyor line 51 on the left / right side of the straddle transport conveyor line 5 of the second unit yard to the container drop point 22 of No. 2 straddle transport loading line, and then changes lanes to drive into the No. 1 straddle transport unloading line 21 to wait for the next unloading container; the quay crane trolley crane grabs the container from the container drop point 24 of No. 4 straddle transport loading line and runs to the top of the first row of the ship that has just been unloaded, and after dropping the loaded container into the first row of storage positions, the quay crane trolley crane moves to the top of the second row of unloading containers and grabs the container. The second row of unloading containers runs with the quay crane trolley crane to the top of the container drop point of No. 1 straddle transport unloading line 21 and drops the container. The quay crane trolley crane runs to the top of the loaded container drop point of No. 2 straddle transport loading line 22 and grabs the container and runs to the ship to carry out loading and unloading;The straddle carrier No. 4 8 waiting in the waiting area of ​​the straddle carrier unloading line 21 of the No. 1 straddle carrier slowly and accurately crosses over the unloading container on the drop-off point, lifts it, and drives to the longitudinal conveying line 51 on the left / right side of the straddle carrier conveying line 5 of the second unit yard; the straddle carrier No. 6 8 drives the loading container from the longitudinal conveying line 51 on the left / right side of the straddle carrier conveying line 5 of the third unit yard into the drop-off point of the straddle carrier loading line 24 of the No. 4 straddle carrier, and then the straddle carrier No. 6 8 changes lanes and drives into the waiting area of ​​the straddle carrier unloading line 23 of the No. 3 straddle carrier to wait for the next unloading container; ..., thus forming a regular cycle until the unloading and loading operations are completed. ;

[0056] Specifically, the interactive operation of containers between the sea-side straddle transport line 5 and the sea-side lifting mechanism 31 of the yard includes: in view of the fact that two longitudinal conveying lines 51, one on the left and one on the right, are arranged on both sides of the lifting shaft of the sea-side lifting mechanism 31, and before the synchronous operation of unloading and loading begins, there is an empty non-powered rail flat car 4 on the longitudinal conveying line 51 on the left side of the straddle transport line 5 waiting for the unloading container, and there is no non-powered rail flat car 4 on the longitudinal conveying line 51 on the right side of the straddle transport line 5, ready for loading; when the operation starts, the straddle carrier 8 carries a unloaded container to the empty non-powered rail flat car 4 on the longitudinal conveying line 51 on the left side of the straddle transport line 5 for the container interactive operation, and after the interactive operation is completed, the straddle carrier 8 changes lanes and moves from the longitudinal conveying line 51 on the left side of the straddle transport line 5 31 descends to the first floor with a heavy-loaded unpowered rail flat car 4 for loading, and a heavy-loaded unpowered rail flat car 4 for loading is moved out of the lifting mechanism 31, and a heavy-loaded unloading container is moved into the lifting mechanism 31; the heavy-loaded unpowered rail flat car 4 for loading is transported to the longitudinal conveying line 51 on the right side of the cross-transportation conveyor line 5, and after the straddle carrier 8 takes away the container, the empty unpowered rail flat car 4 remains on the longitudinal conveying line 51 on the right side of the cross-transportation conveyor line 5 waiting for the next unloading container; after another unloading straddle carrier 8 exchanges containers with the empty unpowered rail flat car 4 on the longitudinal conveying line 51 on the right side of the cross-transportation conveyor line 5, the straddle carrier 8 changes lanes from the longitudinal conveying line 51 on the right side of the cross-transportation conveyor line 5 to the longitudinal conveying line 51 on the left side of the cross-transportation conveyor line 5 to prepare for straddling the loading container, ..., and repeats in this way until the unloading and loading operations are completed. Of course, when unloading and loading are carried out simultaneously, due to the inconsistency between the unloading quantity and the loading quantity, there are one-way operation scenarios of unloading or loading.

[0057] The heavy-loaded unpowered rail flat car 4 is waiting for the lifting mechanism 31 at the intersection of the longitudinal conveying line 51 and the transverse conveying line 52 on the left side of the sea side of the yard. The lifting mechanism 31 carries a heavy-loaded unpowered rail flat car 4 for loading from the 5-story yard to the first-story entrance and exit interaction area. The loading heavy-loaded unpowered rail flat car 4 runs from the lifting mechanism 31 to the interaction area of ​​the transverse conveying line 52 on the sea side of the yard, and then turns to the direction of the longitudinal conveying line 51 on the right side of the loading cross-transport conveyor line 5. The unloading heavy-loaded unpowered rail flat car 4 waiting on the left side enters the lifting mechanism 31.

[0058] Specifically, the interactive operation of containers between the lifting mechanism 31 and the three-dimensional yard 3 includes: after the unloading heavy-loaded unpowered rail flat car 4 enters the lifting mechanism 31, the lifting mechanism 31 carries the unloading heavy-loaded unpowered rail flat car 4 to the 5th floor yard, the unloading heavy-loaded unpowered rail flat car 4 exits the lifting mechanism 31 and enters the yard container longitudinal conveying channel 32, the unloading heavy-loaded unpowered rail flat car 4 drives along the container longitudinal conveying channel 32 to the 16th row reversing area of ​​the landside yard and stops, and after reversing, it moves horizontally to the 16th row of the 16th row of the storage transverse conveying line 33 for storage; after the unloading heavy-loaded unpowered rail flat car 4 is lifted by the lifting mechanism 31, the unloading heavy-loaded unpowered rail flat car 4 is lifted to the 5th floor yard, the unloading heavy-loaded unpowered rail flat car 4 drives out of the lifting mechanism 31 and enters the yard container longitudinal conveying channel 32, the unloading heavy-loaded unpowered rail flat car 4 drives along the container longitudinal conveying channel 32 to the 16th row of the landside yard and stops, and after reversing, it moves horizontally to the 16th row of the storage transverse conveying line 33 of the 16th row for storage; After the structure 31 enters the container longitudinal conveying channel 32, it waits in the waiting area of ​​row 1 left 1 or row 1 right 1 of the first row storage transverse conveying line 33 at the entrance and exit of the lifting mechanism 31. The heavy-loaded non-powered rail flat car 4 moves from row 1 left 1 or row 1 right 1 of the first row storage transverse conveying line 33 of the sea side yard (that is, the waiting area) to the reversing area of ​​the container longitudinal conveying channel 32. After completing the reversal, the heavy-loaded non-powered rail flat car 4 enters the lifting mechanism 31. The lifting mechanism 31 carries the heavy-loaded non-powered rail flat car 4 down to the sea side of the yard via the transverse conveying line 52 to the left / right longitudinal conveying line 51 interaction area, and repeats this cycle.

[0059] Specifically, the interactive operations of containers between the sea side and the land side of the same level of the three-dimensional yard 3 include: from the perspective of the entire process of loading and unloading ships, the sea side yard has stored the containers to be loaded (heavy-loaded unpowered rail flat cars 4) here according to the loading plan, and one row of left 1 container position and one row of right 1 container position of the horizontal conveying line 33 on the left and right sides of the entrance and exit channel of the sea side lifting mechanism 31 are defined as waiting areas; the land side yard has reserved enough storage locations for unloading containers in the land side yard according to the unloading plan, and the empty rail flat cars 4 are stored here in the land side yard.

[0060] Specifically, when the unloading operation begins, the empty and unpowered rail flat cars 4 at the left 1st and left 2nd container positions of the 16th row of storage transverse conveying line 33 in the landside yard pass through the longitudinal conveying channel 32 in turn to the seaside yard, enter the lifting mechanism 31 in turn, descend to the seaside transverse conveying line 52, and switch to the left and right longitudinal conveying lines 51. The empty and unpowered rail flat cars 4 at the left 3 container positions of the 16th row of storage transverse conveying line 33 in the landside yard pass through the longitudinal conveying channel 32 in turn to the seaside yard, enter the lifting mechanism 31 in turn, descend to the seaside transverse conveying line 52, and switch to the left and right longitudinal conveying lines 51. The rail flat car 4 enters the waiting area cache of the 1st row of 1 left box position and the 1st row of 1 right box position of the 1st row of storage transverse conveyor line 33 in the sea side yard. The original 16th row of 16 right box positions and 16th row of 16 right box positions of the 16th row of storage transverse conveyor line 33 in the land side yard are empty and unpowered. The rail flat car 4 is at the 16th row of 1 right box position and the 16th row of 1 right box position of the 16th row of storage transverse conveyor line 33 in the land side yard. After the first unloaded container is raised to the 5th floor yard through the lifting mechanism 31, the heavy-loaded unpowered rail flat car 4 The powered rail flat car 4 enters the container longitudinal conveying channel 32 of the yard and quickly drives toward the 16th row left 1 box position of the 16th row storage transverse conveying line 33 of the land side yard; when the first unloading heavy-loaded unpowered rail flat car 4 quickly drives toward the land side yard, the empty unpowered rail flat car 4 in the waiting area of ​​the 1st row left 1 box position of the first row storage transverse conveying line 33 of the sea side yard moves into the container longitudinal conveying channel 32 and drives into the sea side lifting mechanism 31; when the first unloading heavy-loaded unpowered rail flat car 4 passes through the container longitudinal conveying channel 32 and drives to the 16th row storage transverse conveying line 33 and changes direction to move into the 16th row left 1 box position of the 16th row storage transverse conveying line 33, the empty unpowered rail flat car 4 on the 16th row right 1 box position of the 16th row storage transverse conveying line 33 of the land side yard moves into the container longitudinal conveying channel 32 and drives toward the waiting area of ​​the 1st row left 1 box position of the first row storage transverse conveying line 33 of the sea side yard..., and so on, until the ship is unloaded.

[0061] Specifically, at the beginning of the loading operation, when there are only a few heavy-loaded unpowered rail flat cars 4 left for unloading, the 10th row of left 1 container position of the tenth row of storage transverse conveying line 33 in the sea side yard has been moved into the 1st row of left 1 or 1st row of right 1 container position waiting area of ​​the first row of storage transverse conveying line 33 in the sea side yard. When the unloading heavy-loaded unpowered rail flat cars 4 are lifted to the 5th floor yard along the lifting mechanism 31 and the unloading heavy-loaded unpowered rail flat cars 4 quickly drive to the land side yard, the loading heavy-loaded unpowered rail flat cars 4 in the waiting area move into the container longitudinal conveying channel 32, move into the lifting mechanism 31 and descend to the cross-transport conveying line 5 of the sea side yard. At the same time, After the loaded unpowered rail flat car 4 enters the landside yard, the 10th row left 2 container position of the tenth row storage transverse conveying line 33 of the seaside yard moves into the container longitudinal conveying channel 32 and enters the 1st row left 1 or 1st row right 1 container position waiting area of ​​the first row storage transverse conveying line 33..., and so on. When the unloading task is completed, the loading operation continues, but the loading heavy-loaded unpowered rail flat car 4 entering the lifting mechanism 31 is transported from the lifting mechanism 31 to the straddle transport line 5, and after the straddle carrier 8 takes away the loading container, the empty unpowered rail flat car 4 is left and returns to the 5th floor of the three-dimensional yard through the lifting mechanism 31... and so on. The cycle continues until the loading task is completed.

[0062] Specifically, in order to solve the cost problem, the storage transverse conveyor line can be designed as a linkage mode of the entire conveyor line. For example, the positions of containers at positions 1, 2, and 3 in a row are variable. For example, after the unpowered rail flat car 4 at position 1 moves into the longitudinal conveying channel 32, the positions of the original unpowered rail flat cars 4 at positions 2 and 3 are changed to container positions 1 and 2 in a row, and so on.

[0063] Specifically, in the same level of the yard, when the unloading operation and the loading operation are carried out simultaneously, the synchronous operation of unloading and loading can be achieved through an algorithm based on the above-mentioned unloading and loading operation processes. The hardware of the present invention supports the synchronous operation of unloading and loading. This unloading and loading process is of great significance, which can not only greatly improve efficiency, but also greatly reduce energy consumption.

[0064] Specifically, the container interaction operations between the land-side container trucks and the lifting mechanisms and the 1-2 level entrances and exits in the port collection operation process include: each unit yard in the land-side container interaction area has a high-rise container interaction platform 64 corresponding to a lifting mechanism 31, which is called interaction platform No. 3; there is a container interaction platform 62 on the 1st level, which is called interaction platform No. 1; there is a container interaction platform 63 on the 2nd level, which is called interaction platform No. 2; two container truck parking spaces 61 are arranged on both sides of the interaction platform 64 corresponding to the lifting mechanism 31. When docking at the port, the truck carrying a 40-foot container docks at the port and completes the container delivery and docking procedures. The truck driver receives the container collection information, such as parking space No. 2 of unit yard No. 1 of berth No. 3, and the truck driver drives into the designated parking space; at the same time, the empty non-powered rail flat cars 4 of row 3 right 1 container space, row 3 right 2 container space and row 3 right 3 container space of the third row storage transverse conveying line 33 of unit yard No. 1 of berth No. 3 on the 6th floor of the sea side yard are moved into the container longitudinal conveying channel 32 in sequence, among which the empty non-powered rail flat cars 4 of row 3 right 1 container space quickly drive to the entrance of the land side yard lifting mechanism 31, and the empty non-powered rail flat cars 4 of row 3 right 2 container space and row 3 right 3 container space drive to the sea side yard and are cached on the container longitudinal conveying channel 32; the empty non-powered rail flat cars 4 of row 3 right 1 container space drive into the lifting mechanism 31, and the lifting mechanism 31 descends to the 2nd floor and intersects with row 3 The interactive platform 64 is docked, and the empty unpowered rail flat car 4 is transported to the No. 3 interactive platform 64. At this time, the container truck has just entered the No. 2 parking space and is waiting; when the container truck driver sees the operation indicator light on, he presses the start switch, and the container loader 72 on the truss 71 lifts the port container from the container truck to the empty unpowered rail flat car 4 on the No. 3 interactive platform 64; the heavy-loaded unpowered rail flat car 4 enters the lifting mechanism 31 and rises to the 6th floor and stops. The heavy-loaded unpowered rail flat car 4 quickly drives along the container longitudinal conveying channel 32 to the third row of storage transverse conveying line 33 of the sea side yard, stops and changes direction to drive into the 3rd row right 1 container position, and the two empty unpowered rail flat cars 4 cached in the sea side yard container longitudinal conveying channel 32 and the heavy-loaded unpowered rail flat car 4 on the 3rd row right 1 container position are moved into the 3rd row right 3 container position, the 3rd row right 2 container position, and the 3rd row right 1 container position to stop the empty and heavy-loaded rail flat cars 4.

[0065] Specifically, the port clearance operation includes: after the truck driver picks up a 40-foot container and completes the container pick-up procedures, the driver obtains the container pick-up information of the No. 1 parking space of the No. 4 stereoscopic sub-yard, unit yard, No. 2 berth, and the 17th row of storage horizontal conveying line 33 of the 3rd floor landside yard of the No. 4 stereoscopic sub-yard, 2nd unit yard is the target container, and the 17th row of left 1 container space, 17th row of left 2 container space, and 17th row of left 3 container space (if the 17th row of left 3 container space is also heavy-loaded) are moved into the container longitudinal transmission channel 32 in sequence, among which the 17th row of left 1 container space heavy-loaded non-powered rail flatcar 4 runs two rail flatcars 4 distances toward the sea side, the 17th row of left 2 container space heavy-loaded non-powered rail flatcar 4 moves into the container longitudinal transmission channel 32 to run toward the land side, and the 17th row of left 3 container space heavy-loaded non-powered rail flatcar 4 runs one rail flatcar distance toward the sea side; the 17th row of left 2 container space heavy-loaded non-powered rail flatcar 4 runs to the entrance of the landside lifting mechanism 31 and enters 3, the unloaded unpowered rail flat car 4 is moved into the No. 3 interactive platform 64.

[0066] Specifically, the process of both delivering and picking up containers includes: if the delivered port collection container and the picked up port unloading container are in the same berth yard, when the truck driver goes through the procedures for delivering and picking up the containers, the computer system will automatically set the single business to a certain interactive platform in a certain unit yard of the sub-yard where the unloading container is located as the delivery and pickup location. The container delivery process is the above-mentioned port collection process, and the container pickup process is the above-mentioned port unloading process.

[0067] Specifically, the operation process of 20-foot container collection at the port includes: in the embodiment of the present invention, 20-foot containers are arranged on the 1st and 2nd floors, especially 20-foot containers with a mass of more than 20 tons are arranged on the 1st floor yard. When collecting at the port, when the truck driver goes through the container delivery procedures, the computer system will arrange the truck to stop at a parking space near the No. 1 interactive platform 62 in a certain berth yard, a certain three-dimensional sub-yard, or a certain unit yard. At this time, a 20-foot empty non-powered rail flat car 4 is transported from the 1st floor yard of the unit yard to the No. 1 interactive platform 62, and the container spreader of the container loader and unloader shrinks into a 20-foot spreader, and the 20-foot container on the parking space is lifted onto the 20-foot empty non-powered rail flat car 4 of the No. 1 interactive unit, and the 20-foot heavy-loaded non-powered rail flat car 4 is moved into the 1st floor yard and driven to the seaside yard along the container longitudinal conveying channel 32...

[0068] Specifically, the execution of the pre-shipping operation plan includes: when the container is known to be at the berth with a clear ship date but the loading and stowage diagram is not known, when the container is at the port, the container is first distributed in the 4 three-dimensional sub-yards of the yard based on experience. For example, 40-foot containers are stored on the 6th floor, and 20-foot containers are stored on the 1st or 2nd floor. The so-called pre-shipping plan refers to the centralized storage of containers in the same bay area of ​​the same destination port in the same unit and the same floor yard of the same sub-yard according to the stowage diagram provided by the shipping company. For example, 3 days before the ship berths at the port, the port container terminal receives the loading and unloading ship stowage diagram of the shipping company, and obtains the specific data of how many boxes the ship unloads at that bay and how many boxes are loaded at that destination port. The container terminal will do another pre-loading port yard arrangement, and adjust the containers in the same bay area of ​​the same destination port to the same sub-yard and the same floor yard for storage. The unloaded containers are stored in the same floor yard as the loaded containers.

[0069] Specifically, in the pre-shipping plan, 20-foot container stowage operations. In the first or second floor 20-foot container port yard, in order to facilitate loading, two 20-foot containers with the same destination port and similar container weight need to be put together to facilitate the quay crane trolley to grab them at one time. The computer system completes the consolidation operation of the two 20-foot containers according to the shortest distance. The so-called consolidation operation is to place two 20-foot containers of the same destination port on the same row or two rows of storage transverse conveyor lines 33. When loading, the two 20-foot containers enter the container longitudinal conveying channel 32 one after another with the unpowered rail flat car 4 and enter the lifting mechanism 31 one after another,...

[0070] It should be noted that the above-mentioned operating procedures and methods are only a simple idealized design to express that the new process and new equipment have the ability to adapt to the port container terminal loading and unloading ship collection and distribution operations. The actual process flow can be compiled into a number of operating methods based on the characteristics of the new process equipment, especially the use of digital technologies such as artificial intelligence to compile more efficient operating process methods.

[0071] It should be pointed out that the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
