Abstract
Description
Technical Field
[0001] This invention relates to the field of short-haul transport technology for waterborne solid waste containers, specifically to a short-haul loading and unloading system and method for waterborne solid waste containers. 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 is a highly efficient method for waste reduction, resource recovery, and harmless disposal, and it 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.
[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 short-haul loading and unloading system and method for waterborne solid waste containers, 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 short-haul loading and unloading system for waterborne solid waste containers, including a wharf with berths, a wharf operation platform, and an unloading platform located on the land side of the wharf operation platform, the unloading platform being higher than the wharf operation platform; the wharf operation platform is equipped with a handover operation yard, a quay crane loading and unloading system spanning the handover operation yard and the berth, and a container yard loading and unloading system spanning the handover operation yard and the unloading platform; the unloading platform is equipped with 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 container yard loading and unloading system.
[0008] As one implementation method, the unloading hall is provided with an unloading port connected to the solid waste treatment plant. The horizontal transport system includes an RGV trolley for transporting solid waste containers and an RGV track. The RGV trolley can move back and forth along the RGV track. One end of the RGV track extends to the unloading port, and the other end extends into the operating range of the container yard loading and unloading system.
[0009] As one implementation method, the unloading hall is provided with an entrance and exit for the RGV track and the RGV trolley to pass through. A sealed chamber is provided at the entrance and exit. The RGV track passes through the sealed chamber, and a first sealed door and a second sealed door are respectively provided at both ends of the sealed chamber.
[0010] As one implementation method, the unloading hall is also equipped with a cleaning room for cleaning solid waste containers. The RGV track runs through the cleaning room, which is located between the sealed chamber and the unloading port.
[0011] As one implementation method, multiple discharge ports, RGV trolleys, RGV tracks, sealed chambers, and cleaning rooms are provided and arranged in a one-to-one correspondence.
[0012] As one implementation method, the RGV trolley is equipped with a container bracket for fixing the solid waste container. The container bracket can drive the solid waste container to rotate horizontally and tilt and lift the solid waste container longitudinally.
[0013] As one implementation method, the container yard loading and unloading system includes a solid waste container yard and a gantry crane spanning above the solid waste container yard. The gantry crane can transfer solid waste containers between the handover operation yard and the horizontal transport system.
[0014] The present invention also provides a method for short-haul loading and unloading of waterborne solid waste containers, 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's operating platform grabs the heavy solid waste containers from the ship, moves them to the land side, and places them in the handover operation yard.
[0016] The container yard loading and unloading system grabs the solid waste container load from the handover operation yard, moves it to the landside and places it on the horizontal transport system. The horizontal transport system carries the solid waste container load into the unloading hall connected to the solid waste treatment plant, where the solid waste inside the container load is unloaded.
[0017] The horizontal transport system carries empty solid waste containers out of the unloading hall and into the operating range of the container yard loading and unloading system. The container yard loading and unloading system grabs the empty solid waste containers and places them in the handover operation yard.
[0018] The quay crane loading and unloading system grabs empty solid waste containers from the handover operation yard and puts them back onto the ship.
[0019] 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:
[0020] The horizontal transport system carrying the solid waste container travels to the entrance / exit of the unloading hall connected to the solid waste treatment plant. The first sealed door at one end of the sealed chamber opens, and the horizontal transport system enters the sealed chamber, at which point the first sealed door closes.
[0021] The second sealed door at the other end of the sealed chamber opens, and the horizontal transport system exits the sealed chamber. The second sealed door closes, and the horizontal transport system enters the unloading hall to unload the solid waste from the heavy solid waste container.
[0022] 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 container yard loading and unloading system, including:
[0023] The horizontal transport system carries empty solid waste containers to the cleaning room for cleaning.
[0024] After cleaning, the horizontal transport system travels to the sealed chamber, the second sealed door at one end of the sealed chamber opens, the horizontal transport system enters the sealed chamber, and the second sealed door closes.
[0025] The first sealed door at the other end of the sealed chamber opens, and the horizontal transport system drives out of the sealed chamber. The first sealed door closes, and the horizontal transport system drives out of the unloading hall and into the operating range of the container yard loading and unloading system.
[0026] Compared with the prior art, the present invention has the following beneficial effects:
[0027] (1) The present invention directly sets up the solid waste treatment plant behind the wharf, which can greatly reduce the transportation distance and transportation cost; and adopts the quay crane loading and unloading system to load and unload solid waste containers, and transfers solid waste containers between the quay crane loading and unloading system and the horizontal transportation system through the container yard loading and unloading system, and uses the horizontal transportation system to carry out short-distance transport operations to and from the unloading hall, which greatly improves the loading and unloading efficiency of solid waste containers, thereby improving the material transfer efficiency and significantly reducing long-term operating costs.
[0028] (2) The horizontal transport system of the present invention uses RGV trolleys, which can move back and forth along RGV tracks to transfer solid waste containers between the container yard loading and unloading system and the unloading port of the unloading hall. Within the narrow effective space of the transfer platform, the horizontal transport is independent of each other. The loading and unloading alignment of the RGV trolleys is accurate, and the container brackets can drive the solid waste containers to rotate around the horizontal direction, avoiding the disadvantage of the long time required for traditional gantry cranes to adjust the container direction, and improving the unloading efficiency.
[0029] (3) By setting up a sealed room at the entrance and exit of the unloading hall, the present invention can reduce the leakage of dust and polluting gases, realize full-process sealed management, and reduce environmental pressure; at the same time, a cleaning room is set up in the unloading hall to clean and deodorize the empty solid waste container; and the solid waste in the solid waste container is transported in a sealed manner throughout the process, and is only opened at the unloading port for a moment, which can effectively suppress the diffusion of dust and odor.

[0039] 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.
[0041] 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.
[0042] like Figures 1-2As shown, this embodiment provides a short-haul loading and unloading system for waterborne solid waste containers, including a wharf with berths 1, a wharf operation platform 2, and an unloading platform 7 located on the land side of the wharf operation platform 2. The unloading platform 7 is higher than the wharf operation platform 2. The wharf operation platform 2 is equipped with a handover operation yard 4, a quay crane loading and unloading system spanning the handover operation yard 4 and the berth 1, and a container yard loading and unloading system spanning the handover operation yard 4 and the unloading platform 7. The unloading platform 7 is equipped with a solid waste treatment plant, an unloading hall 10 connected to the solid waste treatment plant, and a horizontal transportation system for transferring solid waste containers between the unloading hall 10 and the container yard loading and unloading system. This embodiment places the solid waste treatment plant directly behind the wharf, which can significantly reduce transportation distance and costs. Furthermore, it uses a quay crane loading and unloading system to load and unload solid waste containers, and transfers solid waste containers between the quay crane loading and unloading system and the horizontal transport system through the container yard loading and unloading system. The horizontal transport system is used for short-haul operations to and from the unloading hall 10, which greatly improves the efficiency of solid waste container loading and unloading operations, thereby improving material transfer efficiency and significantly reducing long-term operating costs.
[0043] The terminal operation area in this embodiment includes two platforms at different elevations. One is the terminal operation platform 2, which can adopt the conventional terminal operation elevation and is used to arrange the container yard loading and unloading system, the handover operation yard 4, and the quay crane loading and unloading system. The other is the unloading platform 7, which is used to arrange the solid waste treatment plant, the unloading hall 10, and the horizontal transportation system, etc. The elevation difference h between the two platforms depends on the height of the solid waste silo inlet of the solid waste treatment plant, and is generally about 10~12m. The two platforms are vertically connected. Berth 1 can berth ships loaded with solid waste containers.
[0044] In some embodiments, the unloading hall 10 is equipped with an unloading port 11 connected to the solid waste treatment plant. The horizontal transport system includes an RGV trolley 8 for transporting solid waste containers and an RGV track 9. The RGV trolley 8 can move back and forth along the RGV track 9. One end of the RGV track 9 extends to the unloading port 11, and the other end extends into the operating range of the container yard loading and unloading system. The container yard loading and unloading system lifts the loaded solid waste containers onto the RGV trolley 8, or the gantry crane 5 lifts the empty solid waste containers from the RGV and unloads them.
[0045] In this embodiment, the solid waste treatment plant is used to process the solid waste loaded in the solid waste container, and can be a waste-to-energy plant, etc. The solid waste treatment plant includes a solid waste silo for storing solid waste, and the unloading hall 10 is connected to the solid waste silo through the unloading port 11.
[0046] like Figure 1 and Figure 2As shown, RGV tracks 9 are arranged on unloading platform 7, perpendicular to the shoreline. One end of RGV track 9 extends into the operating range of the container yard loading and unloading system, and the other end extends into the unloading hall 10 and connects to the unloading port 11. Each RGV track 9 is equipped with an RGV trolley 8, which moves back and forth between the unloading port 11 and the container yard loading and unloading system along the RGV track 9. The container yard loading and unloading system can directly transfer solid waste containers from the handover operation yard 4 to the RGV trolley 8 and lift solid waste containers from the RGV trolley 8 to the handover operation yard 4.
[0047] Preferably, the unloading hall 10 is provided with an entrance / exit for the RGV track 9 and the RGV trolley 8 to pass through. A sealed chamber 12 is provided at the entrance / exit, through which the RGV track 9 passes. A first sealed door and a second sealed door are respectively provided at both ends of the sealed chamber 12. The sealed chamber 12 is a closed space capable of accommodating at least one RGV trolley 8, and both ends are equipped with sealed doors. The RGV trolley 8 enters or exits the unloading hall 10 through the sealed chamber 12. In this embodiment, by providing a sealed chamber 12 at the entrance / exit of the unloading hall 10, the RGV trolley 8, after loading, enters the unloading hall 10 through the sealed chamber 12, reducing the leakage of dust and polluting gas odors. The sealed doors of the sealed chamber 12 close quickly after the RGV trolley 8 passes, reducing the risk of gas escaping from the unloading hall 10 through the sealed chamber 12.
[0048] Preferably, the unloading hall 10 is further equipped with a cleaning room 13 for cleaning solid waste containers. The RGV track 9 passes through the cleaning room 13, which is located between the sealed chamber 12 and the unloading port 11. The cleaning room 13 is an open space capable of accommodating at least one RGV trolley 8, with open ends, and is equipped with cleaning equipment for cleaning solid waste containers. After unloading at the unloading port 11, the RGV trolley 8 enters the cleaning room 13, where the unloaded solid waste containers are cleaned. Afterward, it exits the unloading hall 10 through the sealed chamber 12, thus mitigating environmental pollution from empty solid waste containers. Furthermore, the cleaning room 13 may also be equipped with disinfection equipment for disinfecting empty solid waste containers and / or drying equipment for drying them. After cleaning, the empty solid waste containers can be disinfected and dried before exiting the cleaning room 13.
[0049] Preferably, multiple unloading ports 11, RGV trolleys 8, RGV tracks 9, sealed chambers 12, and cleaning rooms 13 are provided and arranged in a one-to-one correspondence. This embodiment can provide one-to-one correspondence between unloading ports 11, RGV trolleys 8, and RGV tracks 9, thereby forming multiple non-interfering horizontal transport operation groups. This allows for handling of overloaded transport volumes caused by concentrated arrivals in narrow wharves, significantly improving the efficiency of solid waste container loading and unloading operations. Each container yard loading and unloading system can serve at least one horizontal transport operation group. The specific number of horizontal transport operation groups, i.e., the number of unloading ports 11, RGV trolleys 8, and RGV tracks 9, is determined by the transport volume of solid waste containers. The number of sealed chambers 12 and cleaning rooms 13 is set according to the number of RGV trolleys 8 and RGV tracks 9.
[0050] In this embodiment, the unloading hall 10 is a closed hall to prevent gas pollution, and each entrance and exit is equipped with a sealed room 12 and a cleaning room 13 that meet environmental protection requirements. Each RGV track 9 connects to a gantry crane 5 and an unloading port 11 at both ends, and passes through the sealed doors and cleaning rooms 13 of the unloading hall 10. The RGV trolley 8 can automatically travel back and forth along the RGV track 9 to transport solid waste containers.
[0051] In some embodiments, the RGV trolley 8 is equipped with a container bracket for securing the solid waste container. This container bracket can rotate the solid waste container horizontally and tilt and lift it longitudinally. In this embodiment, a rotating device is provided at the bottom of the container bracket, which can rotate the solid waste container 90° horizontally, converting the container from its parallel-to-shore direction to its perpendicular-to-shore direction, so that the container door faces the front of the container bracket and aligns with the unloading port 11. After the solid waste is unloaded and the RGV trolley 8 leaves the unloading hall 10, the rotating device returns to its original position and rotates 90° in the opposite direction, restoring the container bracket from its perpendicular-to-shore direction to its parallel-to-shore direction. A lifting device is provided at the rear of the container bracket, which can tilt the solid waste container downwards from the rear to the front of the container bracket, allowing the solid waste inside the container to be dumped into the storage area, and the container to be emptied by gravity. After the solid waste is unloaded, the lifting device returns to its original position, and the container bracket returns to a horizontal position. Furthermore, a robotic arm is installed at the front end of the container rack. When the solid waste container arrives at the unloading port 11, the robotic arm opens the door at the end of the solid waste container so that the solid waste inside the container can be dumped into the warehouse.
[0052] In some embodiments, the container yard loading and unloading system includes a solid waste container yard 6 and a gantry crane 5 spanning above the solid waste container yard 6. The gantry crane 5 can transfer solid waste containers between the handover operation yard 4 and the horizontal transport system. By setting up the gantry crane 5, the problem of transporting solid waste containers between the terminal operation platform 2 of different heights and the unloading port 11 of the unloading hall 10 is effectively solved. This method saves land compared to the traditional road connection method and is more efficient, effectively saving operating costs. By setting up the solid waste container yard 6 on the terminal operation platform 2 as a buffer zone, loaded and empty solid waste containers transported by the gantry crane 5 can be stacked, providing a key buffer space for the logistics chain and meeting the temporary stacking needs of solid waste containers when the operating capacity of various systems is mismatched. The area of the solid waste container yard 6 is configured to meet the stacking needs of both loaded and empty containers arriving at the same time, and is coordinated with the transport channel of the truck 15.
[0053] The gantry crane 5 and the quay crane 3 loading and unloading system are connected by overlapping working areas serving as a container exchange yard 4. For example... Figure 4 As shown, the process of loading the loaded container into the RGV trolley 8 is as follows: the gantry crane 5 lifts the loaded solid waste container from the handover operation yard 4, the intra-span solid waste container yard 6, or the intra-span truck 15, and places it on the RGV trolley 8 of the horizontal transport system; the process of unloading the empty container from the RGV trolley 8 is as follows: the gantry crane 5 lifts the empty solid waste container from the RGV trolley 8, and places it on the handover operation yard 4, the intra-span solid waste container yard 6, or the intra-span truck 15.
[0054] like Figure 1 As shown, the solid waste container yard 6 is arranged within the span of the gantry crane 5, accommodating the temporary stacking of loaded or empty solid waste containers. Preferably, the gantry crane 5 is a rail-mounted gantry crane 5, capable of longitudinal movement. The sea-side cantilever of the gantry crane 5 shares the handover operation yard 4 with the rear cantilever of the quay crane loading and unloading system. The lifting height of the gantry crane 5 is sufficient to lift the solid waste containers in the handover operation yard 4 onto the RGV trolley 8 of the unloading platform 7.
[0055] 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 handover yard 4. 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 trolley is connected to a spreader for lifting or lowering solid waste containers. The quay crane 3 enables efficient unloading and loading operations of solid waste containers, such as... Figure 3As shown, the unloading process is as follows: the quay crane 3 operates its cantilever, the spreader moves and grabs the solid waste container loaded on the ship, and places it on the in-span truck 15, or in the handover operation yard 4 under the rear cantilever on the land side of the quay crane 3; the loading process is as follows: the quay crane 3 operates its cantilever, the spreader moves and grabs the empty solid waste container on the in-span truck 15 or in the handover operation yard 4 under the cantilever of the quay crane 3, and places it on the ship.
[0056] In this embodiment, the cantilever elevation of the gantry crane 5 is higher than that of the quay crane 3. By setting the quay crane 3 and gantry crane 5 at different heights, their cantilever positions overlap, and a handover operation yard 4 is set up under the overlapping cantilever. Solid waste containers can be seamlessly connected between the quay crane 3 and the gantry crane 5 within the handover operation yard 4, avoiding the scheduling difficulties and low efficiency problems caused by using trucks 15 as short-haul transport in the traditional process. The handover operation yard 4 is set at the intersection of the cantilever of the gantry crane 5 and the cantilever of the quay crane 3. The land side of the quay crane 3 and the sea side of the gantry crane 5 carry out loading and unloading operations of solid waste containers within the handover operation yard 4, mainly completing the loading and unloading of loaded or empty containers. The quay crane 3 can unload loaded solid waste containers to the handover operation yard 4 and wait for the gantry crane 5 to lift them, or the gantry crane 5 can unload empty solid waste containers to the handover operation yard 4 and wait for the quay crane 3 to lift them.
[0057] Furthermore, the wharf operation platform 2 is also equipped with a truck road 14 and trucks 15 (hereinafter referred to as trucks 15). Truck roads 14 are provided within the spans of the gantry crane 5 and the quay crane 3 for the transport of solid waste containers by road. The truck roads 14 are arranged parallel to the shoreline. The width of the truck roads 14 under the spans of the gantry crane 5 and the quay crane 3 is determined according to the road transport volume, and is not less than 7m. It is a one-way traffic system to meet the passage requirements of external trucks 15. Trucks 15 enter from one end of the truck road 14 and exit from the other end. The loading process for trucks 15 within the span of the quay crane 3 is as follows: the quay crane 3 lifts the loaded solid waste containers from the ship and places them on the trucks 15; the unloading process for trucks 15 within the span of the quay crane 3 is as follows: the quay crane 3 lifts the empty solid waste containers from the trucks 15 and places them on the ship. Loading process of truck 15 within the span of gantry crane 5: Gantry crane 5 lifts the loaded solid waste container from RGV trolley 8 or the solid waste container yard 6 within the span and places it on truck 15; Unloading process of truck 15 within the span of gantry crane 5: Gantry crane 5 lifts the empty solid waste container from truck 15 and places it on RGV trolley 8 or the solid waste container yard 6 within the span.
[0058] In this embodiment, depending on the type of solid waste contained in the solid waste container, it can be transported to the unloading hall 10 for unloading through the cooperation of the quay crane loading and unloading system, the container yard loading and unloading system and the horizontal transport system, and then processed at the solid waste treatment plant on the unloading platform 7. Alternatively, it can be transported to an external solid waste treatment plant for processing through the cooperation of the quay crane loading and unloading system and the container truck 15, thereby improving the utilization rate of the terminal.
[0059] In this embodiment, the wharf is equipped with multiple berths 1, and the wharf operation platform 2 is equipped with multiple quay cranes 3, multiple gantry cranes 5, and multiple solid waste container yards 6, with each berth 1, quay crane 3, gantry crane 5, and solid waste container yard 6 arranged in a one-to-one correspondence. The lateral cantilever of the quay crane 3 is arranged laterally, the multiple berths 1 are arranged longitudinally at intervals, the multiple gantry cranes 5 are arranged longitudinally at intervals, and the multiple quay cranes 3 are arranged longitudinally at intervals. The number of gantry cranes 5, quay cranes 3, and berths 1 is determined according to the demand for loading and unloading solid waste containers. The area of the solid waste container yard 6 should be able to meet the storage requirements for both heavy and empty solid waste containers. The corresponding berths 1, quay cranes 3, gantry cranes 5, and solid waste container yards 6 form a loading and unloading operation group to transfer solid waste containers between the horizontal transport system and ships.
[0060] This embodiment also provides a method for short-haul loading and unloading of waterborne solid waste containers, including the following steps:
[0061] When a ship carrying solid waste containers arrives at the dock, the quay crane loading and unloading system on the dock operation platform 2 grabs the heavy solid waste containers on the ship, moves them to the land side, and places them in the handover operation yard 4.
[0062] The container yard loading and unloading system grabs the solid waste container load from the handover operation yard 4, moves it to the land side and places it on the RGV trolley 8 of the horizontal transport system. The RGV trolley 8 of the horizontal transport system carries the solid waste container load into the unloading hall 10 connected to the solid waste treatment plant to unload the solid waste in the solid waste container load.
[0063] The RGV trolley 8 of the horizontal transport system carries the empty solid waste container out of the unloading hall 10 and drives to the working range of the gantry crane 5 of the container yard loading and unloading system. The gantry crane 5 of the container yard loading and unloading system grabs the empty solid waste container and places it in the handover operation yard 4.
[0064] The quay crane loading and unloading system grabs the empty solid waste container in the handover operation yard 4 and puts it back on the ship.
[0065] In some embodiments, the RGV trolley 8 of the horizontal transport system carries a loaded solid waste container into the unloading hall 10 connected to the solid waste treatment plant to unload the solid waste from the container, including:
[0066] The RGV trolley 8 of the horizontal transport system carries the solid waste container to the entrance / exit of the unloading hall 10 connected to the solid waste treatment plant. The first sealed door at one end of the sealed chamber 12 opens, and the RGV trolley 8 of the horizontal transport system enters the sealed chamber 12. The first sealed door closes.
[0067] The second sealed door at the other end of the sealed chamber 12 opens, and the RGV trolley 8 of the horizontal transport system drives out of the sealed chamber 12. The second sealed door closes, and the RGV trolley 8 of the horizontal transport system drives into the unloading hall 10 to unload the solid waste in the solid waste container.
[0068] In some embodiments, the RGV trolley 8 of the horizontal transport system carries the empty solid waste container out of the unloading hall 10 and travels to the operating range of the gantry crane 5 of the container yard loading and unloading system, including:
[0069] The RGV trolley 8 of the horizontal transport system carries the empty solid waste container to the cleaning room 13 for cleaning.
[0070] After cleaning, the RGV trolley 8 of the horizontal transport system travels to the sealed chamber 12. The second sealed door at one end of the sealed chamber 12 opens, and the RGV trolley 8 of the horizontal transport system enters the sealed chamber 12. The second sealed door then closes.
[0071] When the first sealed door at the other end of the sealed chamber 12 is opened, the RGV trolley 8 of the horizontal transport system drives out of the sealed chamber 12. When the first sealed door is closed, the RGV trolley of the horizontal transport system drives out of the unloading hall 10 and travels to the working range of the gantry crane 5 of the container yard loading and unloading system.
[0072] Furthermore, after the gantry crane 5 of the container yard loading and unloading system places the solid waste container on the container rack of the RGV trolley 8 of the horizontal transport system, the container rack rotates the solid waste container 90° horizontally, converting the solid waste container delivered by the gantry crane 5 from parallel to the shoreline to a solid waste container perpendicular to the shoreline, so that the container door faces the front of the container rack and is aligned with the unloading port 11 for easy unloading. Then, the RGV trolley 8 of the horizontal transport system carries the loaded solid waste container into the unloading hall 10. After unloading is completed, when the RGV trolley 8 of the horizontal transport system leaves the unloading hall 10 and travels to the working range of the gantry crane 5 of the container yard loading and unloading system, the container rack rotates the solid waste container 90° in the opposite direction horizontally, so that the container rack returns from the direction perpendicular to the shoreline to the direction parallel to the shoreline, so that the gantry crane 5 of the container yard loading and unloading system can grab the empty solid waste container.
[0073] Furthermore, when unloading solid waste from the solid waste container, the container door is first aligned with the unloading port 11. Then, the robotic arm at the front of the container carriage of the RGV trolley 8 of the horizontal transport system is used to open the container door. Next, the lifting device at the rear of the container carriage tilts the solid waste container downward from the rear of the container carriage to the front of the container carriage, so that the solid waste inside the container is dumped into the warehouse. After the solid waste is unloaded, the lifting device returns to its position and the container carriage returns to horizontal.
[0074] The method of the present invention will be described in detail below through a specific embodiment.
[0075] To handle the overloaded cargo volume caused by concentrated arrivals on the narrow wharf operation platform 2 and unloading platform 7, the wharf has two loading and unloading operation groups and four horizontal transport operation groups. Each loading and unloading operation group serves two adjacent horizontal transport operation groups. Each operation group has its own independent operating area, and parallel operations do not interfere with each other. Each loading and unloading operation group is centered around a quay crane 3 and includes a berth 1, a quay crane 3, a solid waste container yard 6, a handover operation yard 4, and a gantry crane 5. Each horizontal transport operation group is centered around an RGV trolley 8 and includes an RGV trolley 8, an RGV track 9, an unloading port 11, a sealed chamber 12, and a cleaning room 13.
[0076] like Figures 1-7 As shown, a method for short-haul loading and unloading of solid waste containers by water transport is described. Two loading and unloading operation groups can operate simultaneously, and four horizontal transport operation groups can operate simultaneously. Taking one loading and unloading operation group and one horizontal transport operation group as an example, the method includes the following steps:
[0077] 1. Unloading process of the heavy box
[0078] When a ship carrying solid waste containers arrives at the port and enters the corresponding berth 1, the corresponding quay crane 3 operates its cantilever mechanism, the spreader moves and grabs the solid waste container on the ship and moves it to the land side of the dock, and places the solid waste container in the handover operation yard 4 under the land side cantilever of the quay crane 3, or on the container truck 15 inside the span of the quay crane 3.
[0079] The corresponding gantry crane 5 lifts the loaded solid waste container from the handover operation yard 4 and moves it towards the land side; when there is an empty RGV trolley 8 waiting under the land side cantilever of the corresponding horizontal transport system, the gantry crane 5 places the loaded solid waste container on the container rack of the RGV trolley 8; when there is no empty RGV trolley 8 waiting under the land side cantilever of the corresponding horizontal transport system, the gantry crane 5 places the loaded solid waste container in the solid waste container yard 6 within its span, and when there is an empty RGV trolley 8 waiting under the land side cantilever of the gantry crane 5, the gantry crane 5 lifts the loaded solid waste container in the solid waste container yard 6 and places it on the container rack of the RGV trolley 8;
[0080] After the RGV trolley 8 receives the solid waste container loaded by the gantry crane 5, the container bracket secures the container. Then, the container bracket rotates the container 90° horizontally, changing the container from being parallel to the shoreline to being perpendicular to it. The RGV trolley 8 then moves the container to the entrance / exit of the unloading hall 10. At one end of the sealed chamber 12, the first sealed door opens, and the RGV trolley 8 enters the sealed chamber 12, at which point the first sealed door closes. The second sealed door at the other end of 12 opens, and the RGV trolley 8 drives out of the sealed chamber 12, and the second sealed door closes. The RGV trolley 8 drives into the unloading port 11 in the unloading hall 10, aligning the door of the solid waste container with the unloading port 11. Then, the robotic arm at the front end of the container bracket of the RGV trolley 8 opens the door of the solid waste container. Then, the lifting device at the rear end of the container bracket tilts and lifts the solid waste container from the rear end of the container bracket to the front end of the container bracket, so that the solid waste inside the solid waste container is dumped into the warehouse.
[0081] 2. Empty container loading process
[0082] After the solid waste is unloaded from the solid waste container, the lifting device at the rear of the container bracket returns to its original position, and the container bracket is restored to a horizontal position.
[0083] The RGV trolley 8 carries the empty solid waste container to the cleaning room 13. The cleaning equipment in the cleaning room 13 cleans and deodorizes the empty solid waste container. After cleaning, the container door is closed, and the RGV trolley 8 moves to the sealed chamber 12. The second sealed door at one end of the sealed chamber 12 opens, and the RGV trolley 8 enters the sealed chamber 12. The second sealed door closes. The first sealed door at the other end of the sealed chamber 12 opens, and the RGV trolley 8 exits the sealed chamber 12. The first door closes, and the RGV trolley 8 exits the unloading hall 10 and moves into the working range of the gantry crane 5. The container bracket drives the empty solid waste container to rotate 90° in the opposite direction in the horizontal direction, so that the empty solid waste container returns from the direction perpendicular to the shoreline to the direction parallel to the shoreline. The container bracket then releases its fixation on the empty solid waste container.
[0084] The spreader on the corresponding gantry crane 5 moves to the land side, grabs the empty solid waste container on the RGV trolley 8 and moves it to the sea side, and places the empty solid waste container in the solid waste container yard 6 under the span of gantry crane 5, the truck 15 under the span of gantry crane 5, or the handover operation yard 4 under the cantilever of gantry crane 5 on the sea side.
[0085] The quay crane 3 manipulates its cantilever mechanism, and the spreader moves and grabs the empty solid waste container from the handover operation yard 4 under the landside cantilever of the quay crane 3 or the empty solid waste container from the container truck 15 inside the span of the quay crane 3 and places it at the designated location on the ship.
[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
