Description

Technical Field

[0001] This invention relates to the field of waterborne solid waste container technology, specifically to a loading and unloading system and method for waterborne containers at a solid waste treatment plant wharf. Background Technology

[0002] With the accelerating pace of global urbanization and the continuous growth of population, the amount of urban solid waste generated is experiencing explosive growth. Traditional landfill methods not only occupy a large amount of valuable land resources, but also produce leachate and greenhouse gases (such as methane) that pose a serious threat to soil, groundwater, and the atmospheric environment.

[0003] Waste-to-energy incineration, as a highly efficient method for waste reduction, resource recovery, and harmless disposal, has been widely adopted. Large-scale waste-to-energy plants typically need to serve a vast area to achieve economies of scale. However, these large-scale incineration facilities are often located in coastal, riverside, or other remote areas far from urban centers due to factors such as NIMBY (Not In My Backyard) effects, environmental capacity, and land costs. This raises a core challenge: how to economically, efficiently, and cleanly transport the massive amounts of solid waste scattered across various urban collection points to final treatment plants tens or even hundreds of kilometers away.

[0004] Currently, multiple solid waste compression and transfer stations are typically set up within cities or in the suburbs to compress loose household waste and load it into standard containers. These containers are then transported via a short-haul truck to dedicated wharves located in inland or coastal ports. At the wharves, the containers are hoisted onto inland barges or coastal cargo ships using large loading and unloading equipment. From there, the containers are transported in bulk by waterways, which are inexpensive, environmentally friendly, and have a large transport capacity, to downstream or coastal terminal treatment plant wharves. Finally, the waste is unloaded at the treatment plant wharf and transported to the treatment plant via short-haul truck.

[0005] Currently, solid waste treatment plant silos are typically located at considerable height and depth, and are situated at a distance from the dock, requiring transshipment operations between the dock and the downstream treatment plant. The transportation of solid waste containers between the treatment plant and the dock primarily relies on road trucking and rail transport. However, road trucking is inefficient, costly, causes port congestion, and pollutes the environment with diesel trucks. Rail transport has extremely high infrastructure requirements; many ports were not planned with railway lines in their early stages, and it is suitable for large-volume, stable cargo flows, lacking flexibility. Furthermore, solid waste transportation requires effective control of fugitive emissions of dust and odors to prevent secondary pollution; existing transportation methods are difficult to manage in a fully enclosed manner, resulting in significant environmental pressure. Summary of the Invention

[0006] The purpose of this invention is to provide a loading and unloading system and method for waterborne containers at a solid waste treatment plant terminal, which can at least solve some of the defects in the prior art.

[0007] To achieve the above objectives, the technical solution of the present invention is a loading and unloading operation system for waterborne containers at a solid waste treatment plant terminal, comprising a terminal with berths, a terminal platform, and a transfer platform located on the land side of the terminal platform, the transfer platform being higher than the terminal platform; a quay crane loading and unloading system spanning between the transfer platform and the berths is provided on the terminal platform; a solid waste treatment plant, an unloading hall connected to the solid waste treatment plant, and a horizontal transportation system for transferring solid waste containers between the unloading hall and the quay crane loading and unloading system are provided on the transfer platform.

[0008] As one implementation method, the unloading hall is provided with an unloading port connected to the solid waste treatment plant, the transfer platform is provided with a handover area within the operating range of the quay crane loading and unloading system, and the horizontal transport system includes a group of IGV trolleys for transporting solid waste containers, the IGV trolley group can transport solid waste containers between the handover area and the unloading port.

[0009] As one implementation method, the transfer platform is provided with a first transport road for the IGV trolley group to drive from the handover area to the unloading port and a second transport road for the IGV trolley group to drive from the unloading port to the handover area. The first end of the first transport road and the first end of the second transport road are connected at the unloading port. The second end of the first transport road and the second end of the second transport road are connected in the handover area through a third transport road. The second end of the first transport road and the second end of the second transport road both extend to one side to form a turnaround area for the IGV trolley group to wait and change direction.

[0010] As one implementation method, a solid waste container yard is also provided on the wharf platform, and the quay crane loading and unloading system spans over the solid waste container yard.

[0011] As one implementation method, multiple berths, quay crane loading and unloading systems, solid waste container yards, handover areas, and horizontal transport systems are provided and arranged in a one-to-one correspondence.

[0012] As one implementation method, the unloading hall is provided with an entrance for the horizontal transport system to enter, and an airtight chamber is provided at the entrance, with airtight doors at both the entrance and the exit of the airtight chamber.

[0013] As one implementation method, the unloading hall is provided with an exit for the horizontal transport system to exit, and a cleaning room for cleaning solid waste containers is provided at the exit. Both the entrance and exit of the cleaning room are equipped with airtight doors.

[0014] The present invention also provides a method for loading and unloading containers at a solid waste treatment plant terminal, comprising the following steps:

[0015] When a ship carrying solid waste containers arrives at the dock, the quay crane loading and unloading system on the dock platform grabs the heavy solid waste containers from the ship, moves them to the land side, and places them on the horizontal transport system.

[0016] The horizontal transport system carries the loaded solid waste containers into the unloading hall connected to the solid waste treatment plant, where the solid waste inside the containers is unloaded.

[0017] The horizontal transport system carries empty solid waste containers out of the unloading hall and into the operating range of the quay crane loading and unloading system, which then grabs and returns the empty solid waste containers to the ship.

[0018] As one implementation method, the horizontal transport system carries a loaded solid waste container into the unloading hall connected to the solid waste treatment plant, and unloads the solid waste from the container, including:

[0019] The horizontal transport system carries the heavy solid waste container to the airtight chamber at the entrance of the unloading hall. The airtight door at the entrance of the airtight chamber opens, and the horizontal transport system enters the airtight chamber. The airtight door at the entrance closes.

[0020] The airtight door at the outlet of the airtight chamber opens, and the horizontal transport system exits the airtight chamber. The airtight door at the outlet closes, and the horizontal transport system enters the unloading hall to unload the solid waste from the heavy solid waste container.

[0021] As one implementation method, the horizontal transport system carries empty solid waste containers out of the unloading hall and into the operating range of the quay crane loading and unloading system, including:

[0022] The horizontal transport system carries the empty solid waste container to the cleaning chamber at the exit. The airtight door at the entrance of the cleaning chamber opens, and the horizontal transport system enters the cleaning chamber. The airtight door at the entrance closes, and the inside and outside of the empty solid waste container are cleaned.

[0023] After cleaning is completed, the airtight door at the outlet of the cleaning chamber opens, the horizontal transport system drives out of the cleaning chamber, the airtight door at the outlet closes, and the horizontal transport system drives out of the unloading hall and into the operating range of the quay crane loading and unloading system.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) The present invention directly sets up the solid waste treatment plant behind the wharf, which can not only greatly reduce the transportation distance and transportation cost, but also save land significantly; and adopts the quay crane loading and unloading system to load and unload solid waste containers, and conducts short-distance transfer operations between the unloading hall and the quay crane loading and unloading system through the horizontal transportation system, which greatly improves the loading and unloading efficiency of solid waste containers, thereby improving the material transfer efficiency and significantly reducing engineering investment and long-term operating costs.

[0026] (2) The horizontal transport system of the present invention adopts IGV trolley group. Taking advantage of the characteristic that IGV trolley can move freely in both directions, the horizontal transport is independent of each other in the narrow effective space of the transfer platform, while minimizing the cross interference of horizontal transport units, and maximizing the transport efficiency in a limited space.

[0027] (3) By setting up airtight chambers and cleaning chambers at the locations where the horizontal transport system enters and exits the unloading hall, the present invention can reduce the unorganized emission of dust and polluting gases, avoid secondary pollution, achieve full-process closed management, and reduce environmental pressure; and the solid waste in the solid waste container is transported in a closed manner throughout the process, and is only opened momentarily at the unloading port, which can effectively suppress the diffusion of dust and odor.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this invention.

[0035] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0036] like Figures 1-2As shown, this embodiment provides a loading and unloading system for waterborne containers at a solid waste treatment plant 11 wharf. The system includes a wharf with berths 1, a wharf platform 2, and a transfer platform 5 located on the land side of the wharf platform 2, the transfer platform 5 being higher than the wharf platform 2. A quay crane loading and unloading system spans the transfer platform 5 and the berth 1 on the wharf platform 2. The transfer platform 5 includes a solid waste treatment plant 11, an unloading hall 7 connected to the solid waste treatment plant 11, and a horizontal transport system for transferring solid waste containers between the unloading hall 7 and the quay crane loading and unloading system. This embodiment directly places the solid waste treatment plant 11 behind the wharf, significantly reducing transportation distance and costs. Furthermore, the use of the quay crane loading and unloading system for loading and unloading solid waste containers, and the short-distance transfer operation between the unloading hall 7 and the quay crane loading and unloading system via the horizontal transport system, greatly improves the efficiency of solid waste container loading and unloading operations, thereby increasing material transfer efficiency and significantly reducing engineering investment and long-term operating costs.

[0037] Furthermore, the unloading hall 7 is equipped with an unloading port 8 connected to the solid waste treatment plant 11. The transfer platform 5 has a handover area within the operating range of the quay crane loading and unloading system. The horizontal transport system includes a group of IGV trolleys 6 for transporting solid waste containers. These IGV trolleys 6 can transport solid waste containers between the handover area and the unloading port 8. By using the IGV trolleys 6 to transport containers back and forth between the handover area and the unloading port 8, the transfer efficiency between the quay crane loading and unloading system and the solid waste treatment plant 11 can be improved, maximizing transport efficiency within a limited space. Specifically, the IGV trolleys 6 group includes multiple IGV trolleys 6. The IGV trolleys 6 receive loaded solid waste containers from the quay crane loading and unloading system in the handover area, then drive into the unloading hall 7 and stop at the unloading port 8 to unload the loaded solid waste containers. After unloading, they transport the empty solid waste containers to the handover area, awaiting transport by the quay crane loading and unloading system.

[0038] In this embodiment, the solid waste treatment plant 11 is used to treat the solid waste loaded in the solid waste container, and can be a waste-to-energy plant, etc. The solid waste treatment plant 11 includes a solid waste silo for storing solid waste. The unloading hall 7 is connected to the solid waste silo via an unloading port 8. The solid waste container on the IGV trolley 6 is lifted and tilted so that its door is aligned with the unloading port 8, thereby directly dumping the solid waste into the solid waste silo. The transfer platform 5 is located behind the dock and above the dock platform 2 by h meters, where h is generally the depth of the solid waste silo.

[0039] Furthermore, the IGV trolley 6 is equipped with a container rack for placing solid waste containers. A robotic arm is installed at the front end of the container rack, which can automatically open or close the end door of the solid waste container under command. A lifting device is installed at the rear end of the container rack. When the solid waste container reaches the unloading port 8 and the end door of the solid waste container is opened and aligned with the unloading port 8, the lifting device can lift the solid waste container from the rear end under command to dump the solid waste into the warehouse and empty the solid waste container by gravity.

[0040] In some embodiments, the transfer platform 5 is provided with a first transport road 12 for the IGV trolley group 6 to travel from the handover area to the unloading port 8 and a second transport road 13 for the IGV trolley group 6 to travel from the unloading port 8 to the handover area. The first end of the first transport road 12 and the first end of the second transport road 13 are connected at the unloading port 8. The second end of the first transport road 12 and the second end of the second transport road 13 are connected in the handover area through a third transport road 14. The second end of the first transport road 12 and the second end of the second transport road 13 both extend to one side to form a turnaround area 15 for the IGV trolley group 6 to wait and change direction. Each IGV trolley 6 in the IGV trolley group first loads containers on the first transport road 12 in the handover area, then travels along the first transport road 12 to the unloading port 8 in the unloading hall 7 for unloading. After unloading, it travels along the second transport road 13 out of the unloading hall 7 to the handover area for unloading containers. After unloading, the IGV trolley 6 enters the turnaround area 15 at one end of the second transport road 13 to wait. When the IGV trolley 6 in the turnaround area 15 receives a work order, it changes direction and enters the first transport road 12 via the third transport road 14 to load containers, maximizing transport efficiency within a limited space. The IGV trolley 6 can also enter the turnaround area 15 at one end of the first transport road 12 to wait. Each IGV trolley 6 in the IGV trolley group automatically travels back and forth between the handover area and the unloading port 8 of the unloading hall 7 within the working range of the quay crane loading and unloading system on the transfer platform 5 according to a fixed path and work process.

[0041] In this embodiment, the first transport road 12, the second transport road 13, and the third transport road 14 are connected in sequence to form a circular lane. This circular lane can support the simultaneous operation of multiple IGV trolleys 6 in the horizontal transport system, and multiple IGVs are in different states at the same time. Some are loading or unloading in the handover area, some are unloading at the unloading port 8, some are on the road from the first transport road 12 to the unloading port 8, and some are on the road from the second transport road 13 to the handover area. This greatly improves work efficiency and effectively solves the contradiction between small space and large transport volume.

[0042] In this embodiment, the IGV trolley 6 has no front-to-back direction and can operate in both directions without turning around. The direction of entering the unloading hall 7 (the side of the solid waste container's end door) is defined as forward, and the direction of exiting the unloading hall 7 is defined as reverse. When the solid waste container is installed, its door is located at the front end of the container bracket, and the door of the solid waste container always faces the unloading hall 7 during the process of the IGV trolley 6 entering and exiting the unloading hall 7.

[0043] In some embodiments, a solid waste container yard 4 is also provided on the terminal platform 2, and the quay crane loading and unloading system spans over the solid waste container yard 4. By setting up the solid waste container yard 4 on the terminal platform 2 as a buffer zone, loaded and empty solid waste containers transported by the quay crane loading and unloading system can be stacked, providing crucial buffer space for the logistics chain and greatly optimizing logistics turnover efficiency. In this embodiment, the quay crane loading and unloading system loads and unloads solid waste containers between the ship, the solid waste container yard 4, and the IGV trolley 6. The quay crane loading and unloading system is responsible for lifting loaded solid waste containers from the solid waste container yard 4 or the ship and transferring them to the IGV trolley 6, as well as unloading empty solid waste containers from the IGV trolley 6 to the solid waste container yard 4 or the ship.

[0044] Preferably, multiple berths 1, quay crane loading and unloading systems, solid waste container yards 4, handover areas, and horizontal transport systems are provided and arranged in a one-to-one correspondence. This embodiment allows for the establishment of multiple non-interfering work groups, enabling the handling of concentrated arrivals and increased throughput on the narrow transfer platform 5 and wharf platform 2, significantly improving the efficiency of solid waste container loading and unloading operations. The number of work groups is matched to the throughput and loading / unloading volume to ensure continuous and efficient material transfer.

[0045] In some embodiments, the unloading hall 7 is provided with an entrance for the horizontal transport system to enter. An airtight chamber 9 is provided at the entrance, and both the entrance and exit ends of the airtight chamber 9 are equipped with airtight doors. The airtight chamber 9 is an environmentally friendly protective passage connecting the unloading hall 7 and the atmospheric environment. It is a closed space capable of accommodating at least one IGV trolley 6, and both the entrance and exit ends of this closed space are equipped with airtight doors. After the IGV trolley 6 is loaded in the handover area, it enters the unloading hall 7 through the airtight chamber 9, which can reduce the unorganized emission of dust and polluting gas odors. The airtight doors of the airtight chamber 9 close quickly after the IGV trolley 6 passes, reducing the risk of gas escaping from the unloading hall 7 through the airtight chamber 9.

[0046] In some embodiments, the unloading hall 7 is provided with an exit for the horizontal transport system to exit. A cleaning chamber 10 for cleaning solid waste containers is provided at the exit. Both the entrance and exit ends of the cleaning chamber 10 are equipped with airtight doors. The cleaning chamber 10 serves as an environmental protection and container cleaning channel connecting the unloading hall 7 and the atmospheric environment. It is an enclosed space capable of accommodating at least one IGV trolley 6, with airtight doors at both the entrance and exit ends. Cleaning equipment for cleaning solid waste containers is installed within this enclosed space. After unloading at the unloading port 8, the IGV trolley 6 exits the unloading hall 7 through the cleaning chamber 10, allowing for the cleaning of the unloaded solid waste containers while reducing the unorganized emission of dust and polluting odors. The airtight doors of the cleaning chamber 10 close rapidly after the IGV trolley 6 passes, reducing the risk of gas escaping from the unloading hall 7 through the cleaning chamber 10. Furthermore, the cleaning chamber 10 may also be equipped with disinfection equipment for disinfecting empty solid waste containers and / or drying equipment for drying empty solid waste containers. After cleaning the empty solid waste containers, they can be disinfected and dried before leaving the cleaning chamber 10.

[0047] In this embodiment, the unloading port 8, airtight chamber 9, and cleaning chamber 10 are in one-to-one correspondence, and there are multiple of each. Each work group consists of a berth 1, a quay crane loading and unloading system, a solid waste container yard 4, a handover area, a horizontal transport system, at least one unloading port 8, at least one airtight chamber, and at least one cleaning chamber 10. When the number of unloading ports 8, airtight chambers 9, and cleaning chambers 10 exceeds the number of horizontal transport systems, if one IGV trolley 6 in the horizontal transport system occupies the unloading port 8 on its driving path, the other IGV trolleys 6 can choose the nearest unloading port 8, airtight chamber, or cleaning chamber 10 on either side of their driving path to improve transfer and unloading capacity within a limited space.

[0048] In some embodiments, the quay crane loading and unloading system includes a quay crane 3 with a transverse cantilever. The transverse cantilever includes a front cantilever extending above the berth 1 and a rear cantilever extending above the transfer platform 5. A quay crane trolley is also mounted on the transverse cantilever, capable of moving back and forth between the front and rear cantilever along the length of the transverse cantilever. The quay crane 3 is equipped with a spreader for lifting or lowering solid waste containers. The quay crane 3 enables efficient unloading and loading of solid waste containers and loading and unloading of IGV trolleys 6, effectively solving the container transfer problem caused by the elevation difference between the solid waste container yard 4 on the berth 1 and the terminal platform 2 and the solid waste treatment plant 11.

[0049] Furthermore, the quay crane 3 also includes a sea-side gantry and a land-side gantry for supporting the transverse cantilever. The solid waste container yard 4 is located between the sea-side gantry and the land-side gantry, and below the transverse cantilever. The quay crane 3 loads and unloads solid waste containers between the ship, the solid waste container yard 4, and the IGV trolley 6. Each quay crane 3 operates within a relatively fixed berth 1 area and yard zone.

[0050] Preferably, the wharf platform 2 is also equipped with a truck road 17 and a truck 16 (hereinafter referred to as truck 16). Figure 2 As shown, truck roads 17 are provided on both the water and land sides of the quay crane 3, around the solid waste container yard 4, and on one side of the solid waste treatment plant 11 and the unloading hall 7 for trucks 16 to travel on. The width of the truck roads 17 is determined according to the road transport volume, and is not less than 7m. It is a one-way road to meet the passage needs of external trucks 16. Trucks 16 enter from one end of the truck roads 17 and exit from the other end. Loading process for trucks 16 within the span of the quay crane 3: The quay crane 3 lifts the loaded solid waste containers from the ship and places them on the trucks 16; Unloading process for trucks 16 within the span of the quay crane 3: The quay crane 3 lifts the empty solid waste containers from the trucks 16 and places them on the ship.

[0051] In this embodiment, the wharf is equipped with multiple berths 1, and the wharf platform 2 is equipped with multiple quay cranes 3 and multiple solid waste container yards 4, with each berth 1, quay crane 3, and solid waste container yard 4 arranged in a one-to-one correspondence. The lateral cantilever of the quay crane 3 is arranged laterally, and the multiple berths 1 are arranged longitudinally at intervals, as are the multiple quay cranes 3. The number of quay cranes 3 and berths 1 is determined according to the loading and unloading demand of solid waste containers. The area of ​​the solid waste container yard 4 should be sufficient to meet the storage requirements of both heavy and empty solid waste containers.

[0052] In this embodiment, depending on the type of solid waste contained in the solid waste containers, they can be transported to the unloading hall 7 for unloading via a quay crane loading and unloading system and a horizontal transport system. The solid waste is then treated at the solid waste treatment plant 11 at the transfer platform 5. Alternatively, they can be transported to an external solid waste treatment plant 11 via a quay crane loading and unloading system in conjunction with trucks 16, thus improving the utilization rate of the terminal. The area of ​​the solid waste container yard 4 is configured to simultaneously meet the storage needs of both loaded and empty containers arriving at the same time, and is coordinated with the truck road 17.

[0053] This embodiment also provides a method for loading and unloading waterborne containers at the No. 11 wharf of a solid waste treatment plant, including the following steps:

[0054] When a ship carrying solid waste containers arrives at the dock, the quay crane loading and unloading system on dock platform 2 grabs the heavy solid waste containers from the ship, moves them to the land side, and places them on the horizontal transport system.

[0055] The horizontal transport system carries the heavy solid waste container into the unloading hall 7 connected to the solid waste treatment plant 11 to unload the solid waste from the heavy solid waste container.

[0056] The horizontal transport system carries the empty solid waste container out of the unloading hall 7 and into the operating range of the quay crane loading and unloading system. The quay crane loading and unloading system grabs the empty solid waste container and puts it back on the ship.

[0057] In some embodiments, the horizontal transport system carries a loaded solid waste container into the unloading hall 7 connected to the solid waste treatment plant 11 to unload the solid waste from the container, including:

[0058] The horizontal transport system carrying the solid waste container travels to the airtight chamber 9 at the entrance of the unloading hall 7. The airtight door at the entrance of the airtight chamber 9 is opened, and the horizontal transport system enters the airtight chamber 9. The airtight door at the entrance is then closed.

[0059] The airtight door at the outlet of the airtight chamber 9 is opened, and the horizontal transport system drives out of the airtight chamber 9. The airtight door at the outlet is closed, and the horizontal transport system drives into the unloading hall 7 to unload the solid waste from the heavy container of the solid waste.

[0060] In some embodiments, the horizontal transport system carries empty solid waste containers out of the unloading hall 7 and into the operating range of the quay crane loading and unloading system, including:

[0061] The horizontal transport system carries the empty solid waste container to the cleaning chamber 10 at the exit. The airtight door at the entrance of the cleaning chamber 10 is opened, and the horizontal transport system enters the cleaning chamber 10. The airtight door at the entrance is closed, and the inside and outside of the empty solid waste container are cleaned.

[0062] After cleaning is completed, the airlock door at the outlet of cleaning chamber 10 is opened, the horizontal transport system drives out of cleaning chamber 10, the airlock door at the outlet is closed, the horizontal transport system drives out of unloading hall 7 and drives into the operating range of the quay crane loading and unloading system.

[0063] Furthermore, when unloading solid waste from the solid waste container, an automatic alignment technology is used to ensure that the IGV trolley 6 of the horizontal transport system stops precisely in front of the unloading port 8 in the unloading hall 7, and that the solid waste container door is precisely aligned with the unloading port 8. This overcomes the drawback of the traditional truck 16 requiring repeated direction adjustments, and significantly improves unloading efficiency and system automation level.

[0064] The method of the present invention will be described in detail below through a specific embodiment.

[0065] To handle the overloaded throughput caused by concentrated arrivals on the narrow transfer platform 5 and quay platform 2, the terminal is equipped with three operation groups, each with its own independent operating area, allowing parallel operations without mutual interference. Each operation group is centered around a quay crane 3 and includes a berth 1, a quay crane 3, a solid waste container yard 4, a handover area, a horizontal transport system, a discharge port 8, at least one airtight chamber, and at least one cleaning chamber 10; a horizontal transport system may include multiple IGV trolleys 6.

[0066] like Figures 1-3 As shown, a method for loading and unloading waterborne containers at the No. 11 wharf of a solid waste treatment plant is described. Three work groups can operate simultaneously. Taking one of the work groups as an example, the method includes the following steps:

[0067] 1. Unloading

[0068] When a ship carrying solid waste containers arrives at the port, it enters the corresponding berth 1. The corresponding quay crane 3 operates its cantilever mechanism, and the spreader moves and grabs the solid waste container from the ship and moves it to the land side of the dock.

[0069] IGV unloading: When an empty IGV trolley 6 of the corresponding horizontal transport system is waiting for container loading in the handover area, the quay crane 3 places the loaded solid waste container onto the IGV trolley 6.

[0070] Unloading at the container yard: When the corresponding horizontal transport system's empty IGV trolley 6 is waiting for container loading in the handover area, the quay crane 3 places the loaded solid waste container in the corresponding solid waste container yard 4. After the handover area has an empty IGV trolley 6, the quay crane 3 lifts the loaded solid waste container in the solid waste container yard 4 onto the IGV trolley 6.

[0071] 2. Unloading

[0072] The IGV trolley 6 receives the solid waste container loaded directly from the ship by the corresponding quay crane 3 or from the solid waste container yard 4. After the solid waste container is fixed on the container rack of the IGV trolley 6, the IGV trolley 6 travels forward along the first transport road 12 to the unloading hall 7. The solid waste container door is located in front of the direction of travel of the IGV trolley 6. Before the IGV trolley 6 reaches the corresponding airtight chamber, it opens the inlet airtight door. After the IGV trolley 6 enters, it closes the inlet airtight door and then opens the outlet airtight door. The IGV trolley 6 enters the unloading hall 7 and closes the outlet airtight door.

[0073] After the IGV trolley 6 arrives at the unloading hall 7, it drives to the corresponding unloading port 8, aligns the container door with the unloading port 8, and the robotic arm at the front of the container bracket automatically opens the end door of the solid waste container. The lifting device at the rear of the container bracket lifts the solid waste container from the non-door end and uses gravity to pour the solid waste into the unloading port 8. After unloading is completed, the bracket returns to a horizontal position.
