Description

Technical Field

[0001] This utility model relates to the field of transshipment, specifically to a container transshipment device for port use in water transport engineering. Background Technology

[0002] Against the backdrop of global economic integration, international trade activities are becoming increasingly frequent. Water transport, as one of the most important modes of transportation in international trade, handles approximately 90% of global freight volume. Container shipping, with its significant advantages such as standardization, efficiency, and safety, has become the mainstream mode of waterborne freight transport. As a crucial node in the container transport chain, waterway ports serve as hubs for the conversion between sea and land transport. The efficiency of container loading, unloading, and transshipment directly impacts the operational efficiency and cost of the entire logistics supply chain.

[0003] With the continuous growth of international trade, the container throughput of ports is constantly increasing. Larger container ships are carrying increasingly larger containers; for example, some ultra-large container ships can carry over 20,000 TEUs. This places higher demands on the container handling and transshipment capabilities of ports. Ports need to unload containers from ships quickly and accurately and transfer them to storage yards, or load containers from storage yards onto ships for transport to their destinations.

[0004] Currently, the container transshipment equipment used by ports for container loading, unloading and transshipment operations has many drawbacks and is difficult to meet the ever-increasing transportation demand.

[0005] In container lifting operations, traditional transfer devices mostly use hydraulic lifting systems. While hydraulic systems can provide significant lifting force, their response speed is slow, requiring considerable time to adjust the height of the container spreader. Furthermore, the control precision of hydraulic systems is limited, making it difficult to achieve fast and accurate lifting operations. In actual operation, speed fluctuations in the hydraulic system often cause containers to sway during lifting, increasing the risk of collision damage and reducing operational safety and reliability. Simultaneously, hydraulic systems have high maintenance costs and are prone to leaks and other malfunctions, affecting normal port operations. These problems result in traditional hydraulic lifting systems completing fewer container lifting operations per unit time, severely restricting the efficiency of container loading and unloading at ports, extending ship dwell time in port, and slowing down cargo turnover.

[0006] Regarding the mobility of transshipment devices, some existing devices suffer from insufficient power and unstable movement. They struggle to move quickly and flexibly between different port operating areas and cannot efficiently connect with various transport vehicles such as ships and trucks. Unloading containers from ships to docks, loading them onto trucks, or transferring containers between different yards within the port often requires multiple intermediate handling steps, increasing time costs and increasing the risk of container damage. Furthermore, existing transshipment devices are poorly adaptable to the complex port operating environment and cannot meet the diverse transshipment needs of ports. Therefore, we propose an improvement: a container transshipment device for waterway engineering ports. Utility Model Content

[0007] The purpose of this utility model is to address the problems raised in the existing background technology. To achieve the above-mentioned purpose, this utility model provides the following technical solution: a container transfer device for a water transport port, comprising a main container transfer beam and a protective outer railing disposed on the main container transfer beam. Container transfer auxiliary beams are fixed on both sides of the main container transfer beam, and two auxiliary container transfer beams are provided. Bottom supports are welded to the bottom of both the main container transfer beam and the auxiliary container transfer beams. Container lifting servo motors are installed on the auxiliary container transfer beams, and two container lifting servo motors are also provided and symmetrically arranged.

[0008] As a preferred technical solution of this utility model, the container lifting servo motor is equipped with a reducer, and wire rope drums are rotatably connected to both sides of the reducer. The outer surface of the wire rope drum is embedded with a drum anti-slip groove.

[0009] As a preferred technical solution of this utility model, a rotating wheel is provided on one side of the wire rope drum, a fixing plate is installed on the rotating wheel, and the rotating wheel is installed on the container transfer sub-beam through the fixing plate.

[0010] As a preferred technical solution of this utility model, the outer wheel groove of the rotating wheel is connected to the container transfer wire rope, and the wire rope drum is also wound with the container transfer wire rope.

[0011] As a preferred technical solution of this utility model, a walking motor is installed on the bottom bracket, and a walking speed reducer is connected to one side of the walking motor.

[0012] As a preferred technical solution of this utility model, a container spreader is provided below the main beam for container transfer, and a wheel frame is fixed to the top of the container spreader, with a spreader wheel embedded in the wheel frame.

[0013] As a preferred technical solution of this utility model, a rotating shaft is connected between the wheel frame and the spreader wheel, and the rotating wheel and the spreader wheel are connected to each other by the container transfer wire rope.

[0014] As a preferred technical solution of this utility model, a container telescopic clamping arm is fixed on the outer side of the container spreader. The container telescopic clamping arm is provided with a fixing hole, and a bolt can be embedded in the fixing hole to provide stability for the container telescopic clamping arm.

[0015] As a preferred technical solution of this utility model, container twist locks are installed at the lower corners of the four corners of the container spreader, and the container body is connected under the container twist locks.

[0016] Compared with existing technologies, the beneficial effects of this utility model are as follows: The combined design of the container lifting servo motor, reducer, and wire rope drum enables rapid and precise lifting operations of containers. The high torque output and precise speed control characteristics of the servo motor allow the wire rope drum to stably wind and unwind the wire rope, quickly adjusting the height of the container spreader. Compared with traditional hydraulic lifting systems, this mechanical lifting method has a faster response speed, enabling more container lifting operations to be completed per unit time, effectively improving the loading and unloading efficiency of containers in ports, reducing ship dwell time in port, and accelerating cargo transfer and turnover.

[0017] During the container lifting process, the precise control of the servo motor by the control system ensures that the container rises or falls at a uniform and stable speed, avoiding the risk of container swaying and collision caused by speed fluctuations, and ensuring the safety and reliability of the operation.

[0018] The traveling motor and reducer mounted on the bottom support provide powerful support and smooth movement for the entire transfer unit. It can move quickly and flexibly between different operating areas in the port, facilitating seamless docking with various transport vehicles such as ships and trucks. Whether unloading containers from ships to the dock, loading them onto trucks, or transferring containers between different yards within the port, the traveling motor drives the entire process efficiently, reducing intermediate handling steps and time costs, and significantly improving overall logistics efficiency.

[0019] The rotating disc and the spreader wheel are connected by a container transfer wire rope, allowing the container spreader to remain horizontal during lifting and lowering, and to achieve smooth turning and precise alignment during translation. This design ensures accurate alignment of container corner fittings during container transfers from one ship to another or from a ship to quay facilities, avoiding collisions and damage caused by positional deviations, and improving the accuracy and quality of container transfer.

[0020] The main container transfer beam, as the primary load-bearing structure of the entire system, possesses high strength and excellent rigidity. Secondary container transfer beams are fixed to both sides, and both are welded to bottom supports, forming a stable triangular support structure. This effectively distributes the load generated during container lifting, ensuring the stability and safety of the entire system under heavy loads. Even when lifting large, heavy containers, the structure remains undeformed and unbreakable, providing reliable protection for port operations.

[0021] Installing protective railings on the main beams of container transfer stations not only prevents workers from accidentally falling during operations, but also, to a certain extent, blocks external objects from impacting the internal structure of the equipment and the workers, thus playing a safety protection role. At the same time, the presence of protective railings also standardizes the operating area for workers, reducing the risk of safety accidents caused by human error.

[0022] The outer surface of the wire rope drum is embedded with anti-slip grooves, a crucial safety design feature. During the winding and unwinding process, these grooves increase the friction between the wire rope and the drum, effectively preventing slippage. This is especially important when lifting heavy containers, ensuring the wire rope remains securely wound on the drum, preventing container falls due to slippage and significantly improving operational safety.

[0023] The container spreader is equipped with container twist locks at each of its four corners. These twist locks engage tightly with the corner fittings on the container body, forming a reliable locking mechanism. During lifting, the twist locks can withstand the weight of the container and various external forces, preventing the container from accidentally detaching. Simultaneously, the container telescopic gripping arm has fixing holes for inserting bolts to further reinforce the connection between the gripping arm and the container, ensuring the container remains stable throughout the entire lifting process and eliminating the risk of the container slipping.

[0024] The container spreader has a telescopic container clamping arm fixed to its outer edge, and the clamping arm has fixing holes for bolts to be inserted for secure fixing. This design allows operators to quickly and easily adjust the position of the clamping arm to achieve a tight grip on containers of different sizes. Operation is simple and intuitive, requiring no complex tools or highly skilled operators; ordinary workers can master it after brief training, reducing operational difficulty and labor intensity, and improving work efficiency.

[0025] All moving parts of the entire transfer device, such as the walking motor, the container lifting servo motor, and the telescopic clamping arm, can be operated through a centralized control system. Operators can precisely control the device's various actions from the control room via the operating interface, eliminating the need to operate the equipment directly in harsh outdoor environments. This not only improves operational comfort but also reduces the impact of on-site environmental factors on operational accuracy, further enhancing work efficiency and safety.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Example 1: A container transfer device for a water transport port includes a container transfer main beam 1 and a protective outer railing 2 installed on the container transfer main beam 1. Container transfer auxiliary beams 3 are fixed on both sides of the container transfer main beam 1, and there are two container transfer auxiliary beams 3. Bottom supports 4 are welded to the bottom of both the container transfer main beam 1 and the container transfer auxiliary beams 3. Container lifting servo motors 5 are installed on the container transfer auxiliary beams 3, and there are also two container lifting servo motors 5 arranged symmetrically.

[0031] The container lifting servo motor 5 is equipped with a reducer 6, and wire rope drums 7 are rotatably connected to both sides of the reducer 6. The outer surface of the wire rope drums 7 is embedded with anti-slip grooves 8. A rotating wheel 9 is provided on one side of the wire rope drum 7, and a fixing plate 10 is installed on the rotating wheel 9. The rotating wheel 9 is mounted on the container transfer sub-beam 3 through the fixing plate 10.

[0032] The outer wheel groove of the rotating wheel 9 is connected to the container transfer wire rope 11, and the wire rope drum 7 is also wound with the container transfer wire rope 11. A travel motor 12 is installed on the bottom support 4, and a travel reducer 13 is connected to one side of the travel motor 12. A container spreader 14 is set below the container transfer main beam 1, and a wheel frame 15 is fixed to the top of the container spreader 14. A spreader wheel 16 is embedded in the wheel frame 15.

[0033] A rotating shaft 17 connects the wheel frame 15 and the spreader wheel 16, and the rotating wheel 9 and the spreader wheel 16 are connected to each other by a container transfer wire rope 11.

[0034] A container telescopic clamping arm 18 is fixed to the outer edge of the container spreader 14. The container telescopic clamping arm 18 is provided with fixing holes 19, into which bolts can be inserted to provide stability for the container telescopic clamping arm 18. Container spinlocks 20 are installed at the lower corners of the four corners of the container spreader 14, and the container body 21 is connected to the bottom of the container spinlocks 20.

[0035] Working principle of container transshipment device for waterway engineering ports: This container transshipment device mainly consists of a main frame composed of a container transshipment main beam 1, a protective outer railing 2, a container transshipment secondary beam 3, and a bottom support 4. The bottom support 4 provides a stable support foundation for the entire device. The combination of the traveling motor 12 and the traveling reducer 13 installed on it can drive the entire device to move flexibly within the designated area of ​​the port to adapt to the needs of different operating positions.

[0036] Two symmetrically arranged container lifting servo motors 5 are installed on the container transfer sub-beam 3 to ensure the smoothness and synchronization of the lifting action. The servo motors 5 serve as the power source, transmitting power and reducing speed and torque through a connected reducer 6. The wire rope drums 7, rotatably connected to both sides of the reducer 6, rotate under power. Because the outer surface of the wire rope drums 7 is embedded with anti-slip grooves 8, slippage of the wire rope during winding is effectively prevented, ensuring stable transmission of lifting force.

[0037] The rotating wheel 9 is mounted on the container transfer sub-beam 3 via a fixing plate 10. The container transfer wire rope 11 is connected to the groove of its outer wheel, and the wire rope drum 7 is also wound with the container transfer wire rope 11. When the servo motor 5 starts, it drives the wire rope drum 7 to rotate, winding and unwinding the container transfer wire rope 11, thus raising or lowering the container spreader 14. By precisely controlling the speed and direction of the servo motor 5, the lifting height and speed of the container can be accurately controlled to meet the loading and unloading requirements of containers of different sizes.

[0038] The container spreader 14 is located below the main container transfer beam 1 and is a key component that directly contacts and lifts the container body 21. A wheel frame 15 is fixed to its top, and the spreader wheel 16 embedded in the wheel frame 15 is connected to the wheel frame 15 through a rotating shaft 17, allowing the spreader wheel 16 to rotate freely within the wheel frame 15 and reducing friction during the lifting process.

[0039] The container telescopic clamping arm 18 on the outer side of the container spreader 14 can be extended and adjusted according to the size of the container. The bolts in the fixing holes 19 can be used to fix the position of the clamping arm, ensuring stable and reliable clamping of containers of different sizes. After the container spreader 14 is lowered to a suitable height, the operator can control the telescopic clamping arm 18 to make it fit tightly against the container body 21, and then use the container twist lock 20 to further lock the container to prevent the container from slipping during the lifting process.

[0040] When a container needs to be transferred, the first step is to start the travel motor 12, which drives the entire device to move to a suitable position above the container to be transferred via the travel reducer 13. Then, the container lifting servo motor 5 is started, causing the spreader 14 to descend to the top of the container. The operator then controls the telescopic clamping arm 18 to clamp and lock the container. Next, the servo motor 5 is started in reverse to lift the container to the required height. The travel motor 12 is then started again to transfer the container to the target position. Finally, the container is slowly lowered, completing the entire transfer process. Throughout this process, all components work together, achieving efficient and safe container transfer operations through precise control and a stable mechanical structure, thus improving the loading and unloading efficiency and logistics turnover speed of ports in waterway engineering.

[0041] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described herein. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific implementation methods described above. Therefore, any modifications or equivalent substitutions to the present utility model, as well as all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
