Description

Technical Field

[0001] The embodiments of this utility model belong to the field of container transshipment and loading / unloading technology, and more specifically, relate to a railway container-to-bulk loading / unloading system. Background Technology

[0002] In modern logistics systems, containerized transport of bulk cargo is becoming an increasingly common choice. For bulk commodities such as grain, coal, or ore, container transport can improve transportation efficiency and safety. However, under specific needs, it is necessary to unpack containers and transship bulk cargo in bulk form; this process is called "container-to-bulk" conversion. For example, coal from Northwest China can be transported by rail in containers to container terminals in Chongqing and Sichuan. At these terminals, through the container-to-bulk conversion method, the coal is converted into bulk cargo and loaded onto cargo ships docked at water transport terminals, completing multimodal transport of bulk cargo. Adopting the container-to-bulk conversion method can better adapt to the special characteristics and transportation needs of bulk commodities. By converting bulk cargo to bulk form, loading, unloading, and transportation can be more flexible, improving transportation efficiency and reducing transportation costs. At the same time, the container-to-bulk conversion method can also meet the demand for bulk cargo in specific regions or industries, further promoting the development of logistics networks and the improvement of transportation systems.

[0003] In traditional container-to-bulk-cargo conversion methods, the operation typically involves directly loading containers onto ships at the terminal. In this method, containers are transported from the freight yard to the quayhead, where bulk cargo is directly dumped into the ship's hold using steel cables suspended by loading and unloading equipment or specialized spreaders. However, this direct loading method has several problems: 1. The need for lifting equipment to suspend and unload containers is time-consuming and labor-intensive. Furthermore, the need to handle each container individually slows down the loading process, hindering efficient loading and unloading operations. 2. The significant height difference between the container and the ship's hold during the direct dumping process increases the risk of collisions and friction, generating dust that pollutes the environment and may harm personnel. 3. Due to dust generation and environmental pollution, direct loading places high demands on environmental protection. In some regions or industries with stringent environmental standards, this method cannot meet relevant environmental regulations. Utility Model Content

[0004] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a railway container-to-bulk loading and unloading system. This system facilitates the conversion of bulk cargo from containerized to bulk cargo handling, reducing the drop height of the cargo as it is unloaded from containers to designated locations. This reduces operational time and manpower consumption, improves loading and unloading efficiency, and also lowers transportation time and labor costs, enhancing overall logistics efficiency. Furthermore, the reduced drop height also minimizes material collisions and friction during unloading, thus reducing dust generation and contributing to air quality protection and environmental pollution reduction, which is particularly important in areas or industries with high environmental requirements. Additionally, it helps protect the quality and integrity of the goods.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figures 1 to 4As shown, this utility model embodiment provides a railway container-to-bulk loading and unloading system, including a transport unit, a hoisting unit, and a container-to-bulk unit. The hoisting unit is located on the ground in the middle of the transport unit; the container-to-bulk unit is fixedly installed above one side of the transport unit. During container-to-bulk operations, the hoisting unit lifts the container 4 from one side of the transport unit onto the container-to-bulk unit, and then the bulk cargo inside the container 4 is unloaded onto the transport unit below the container-to-bulk unit, allowing the bulk cargo to be sequentially transferred to the designated location. By using this utility model's loading and unloading system for bulk cargo container-to-bulk operations, the drop height when the bulk cargo is dumped from the container to the designated location is reduced, decreasing operation time and manpower consumption, improving loading and unloading efficiency, reducing transport time and labor costs, and enhancing overall logistics efficiency. Furthermore, the reduced drop height also helps reduce material collisions and friction during the dumping process, thereby reducing dust generation and contributing to air quality protection and environmental pollution reduction, which is especially important in areas or industries with high environmental requirements. In addition, it also helps protect the quality and integrity of the goods.

[0031] like Figure 1 and Figure 2 As shown, the transportation unit includes a freight train 2, a train track 3, and a conveyor belt 7. The train track 3 is located on the upper surface of the working ground 8, below one cantilever of the container crane 1, and the freight train 2 is mounted on it to transport containers loaded with bulk cargo to the unloading area. The conveyor belt 7 is located on the upper surface of the working ground below the corresponding cantilever of the container crane 1, and is used to transport the bulk cargo converted from containerized to bulk cargo to a designated location. By using the freight train 2 and the conveyor belt 7 to transport containers 4 and bulk cargo respectively, it facilitates the simultaneous operation of multiple pieces of equipment in the lifting unit and the container-to-bulk-cargo conversion unit, reduces the operation time and labor costs in intermediate links, avoids waiting time and queuing, improves the efficiency of container-to-bulk-cargo conversion operations, and is suitable for large-scale bulk cargo transshipment needs.

[0032] like Figure 1 and Figure 2As shown, the lifting unit includes: a container crane 1, a container yard 5, and crane rails 9. Multiple crane rails 9 are fixed to the working ground, with their axes aligned with the axis of the transport unit, for the lifting unit to run along the rails. The container yard 5 is fixed to the working ground in the middle of the multiple crane rails 9, providing a temporary storage point for containers 4 loaded with bulk cargo and / or empty containers. The container crane 1 is located on the upper surface of the crane rails 9, used to lift containers 4 from freight trains 2 to the container yard 5 or the bulk cargo conversion unit, or to lift containers 4 unloaded from the bulk cargo conversion unit to the container yard 5 or the freight train 2. By placing the lifting unit in the middle of the transport unit, the lifting operation distance is shortened, reducing the time and manpower required for lifting, which helps to improve operational efficiency, shorten the time of the entire loading and unloading process, and improve the efficiency of logistics transportation. It also reduces the lifting operation time of operators and the risks of working at height, reducing the possibility of accidents. At the same time, it reduces the use time and energy consumption of lifting equipment, lowers the energy cost in the logistics transportation process, and achieves the effect of energy conservation and emission reduction. In addition, by placing the lifting unit in the middle of the transport unit, the lifting position and height can be flexibly adjusted to adapt to different types and sizes of containers, meet the loading and unloading needs in different scenarios, and optimize the effect of logistics transportation.

[0033] Preferably, the container 4 includes at least one of a bottom-opening container and a rear-opening container.

[0034] like Figures 1 to 4As shown, the bulk cargo conversion unit includes a bulk cargo conversion platform 6. Multiple bulk cargo conversion platforms 6 are fixedly installed above the conveyor belt 7. Each platform also includes a steel frame 601, a hollow bearing plate 602, an automatic container lock 603, a rotating shaft 604, a first hopper 605, a second hopper 606, a hydraulic rod 607, and a dust cover 608. The steel frame 601 is fixed to the working ground and located above the conveyor belt 7 to support other components. The second hopper 606 and the first hopper 605 are fixedly installed on both sides of the steel frame 601 along the conveyor belt 7 to stabilize the material flow. The discharge ports of both hoppers face the conveyor belt 7 to reduce the drop height of bulk materials. The rotating shaft 604 is fixed to the middle of the steel frame 601 between the second hopper 606 and the first hopper 605. 1. Upper surface; Hollow bearing plate 602 is located above the second collection hopper 606 and is movably connected to the steel structure frame 601 via a rotating shaft 604; Multiple container automatic locks 603 are fixedly installed around the upper surface of the hollow bearing plate 602 to lock the container 4 hoisted to the upper surface of the hollow bearing plate; Multiple hydraulic rods 607 are fixedly connected at one end to the steel structure frame 601 above the second collection hopper 606 and at the other end to the hollow bearing plate 602 to push the hollow bearing plate 602 to rotate around the rotating shaft 604 at a certain angle; A detachable dust cover 608 is fixedly installed on the upper surface of the steel structure frame 601 above the first collection hopper 605 and is adapted to the size of the container, so as to reduce dust when the container 4 is unloaded from the first collection hopper 605. By reducing the drop height during bulk cargo transfer through the centralized-to-bulk platform 6, it is beneficial to reduce material collisions and friction during the unloading process. Combined with the dust cover 608, it further reduces dust generation, which helps protect air quality and reduce environmental pollution. This is especially important in areas or industries with high environmental requirements, and it also helps protect the quality and integrity of goods.

[0035] Preferably, the upper opening of the second hopper 606 is adapted to the bottom-opening container.

[0036] Preferably, the upper opening of the first hopper 605 is adapted to the tail-opening type container.

[0037] Preferably, the hollow support plate 602 rotates within a range of 0 to 70 degrees about the rotation axis 604.

[0038] Preferably, the container automatic lock 603 includes at least one of an automatic hydraulic lock and an electronic automatic lock.

[0039] To further illustrate, the operating principle of this utility model is as follows: Container crane 1 lifts container 4 from freight train 2 to container yard 5 for temporary storage, or directly places container 4 on the container-to-bulk conversion platform 6 for container-to-bulk conversion. When container 4 is a bottom-opening container, when container crane 1 lifts container 4 onto hollow support plate 602, container automatic lock 603 automatically locks container 4, opening the bottom door of container 4. The bulk cargo inside container 4 falls directly into the second collection hopper 606 and is transported to a designated location via the bottom conveyor belt 7. After container 4 is emptied, container automatic lock 603 unlocks, and container crane 1 lifts the empty container 4 to container yard 5 for temporary storage, starting the next work cycle. When container 4 is a tail-opening container, when container crane 1 lifts container 4 onto hollow support plate 602, container automatic lock 603 locks container 4 automatically, opening the tail door of container 4. Hydraulic rod 607 slowly and evenly pushes hollow support plate 602 to rotate to 60 degrees, and the bulk cargo inside container 4 falls directly into the first collection hopper 605 and is transported to the designated position by the bottom belt conveyor 7. After container 4 is unloaded, hydraulic rod 607 rotates container 4 to a horizontal position, container automatic lock 603 unlocks, and rail-mounted container gantry crane 3 lifts the empty container 2 to the railway container yard for stacking, starting the next work cycle.
