Description

Technical Field

[0001] The present invention relates to the technical field of rail transit freight automation, and particularly to a high-speed rail freight rapid loading and unloading device and a high-speed rail freight rapid loading and unloading method. Background Art

[0002] Currently, in the field of high-speed rail freight loading and unloading, common means have significant limitations. Manual loading and unloading rely on manual handling, which is not only inefficient but also prone to overtime problems due to heavy workloads, making it difficult to meet the requirements of modern logistics for efficient transportation. In addition, semi-automated equipment such as small forklifts, although improving the loading and unloading efficiency to a certain extent, requires reserved operating space on the platform, conflicting with the compact design of high-speed rail platforms and restricting its widespread application.

[0003] To solve the above problems, various improvement schemes have been tried at home and abroad, but the existing technical bottlenecks have not been completely broken through. For example, China adopted a method of combining manual handling with detachable shelves for the cargo hold transformation of CRH2J-type multiple units, attempting to improve the loading and unloading flexibility; the TGV La Poste train in Europe is equipped with a roller conveyor belt inside the carriage, but this system is only applicable to small postal parcels and cannot adapt to the loading and unloading requirements of larger or heavier goods. Although these methods have certain effects in specific scenarios, they expose problems such as poor compatibility and limited applicability.

[0004] Generally speaking, the existing high-speed rail freight loading and unloading technologies still face core problems such as low efficiency, insufficient automation, poor compatibility, and lack of standardization. The existence of these problems not only affects the overall operation efficiency of high-speed rail freight but also restricts its further development in the modern logistics system.

[0011] The present invention also provides a method for rapid loading and unloading of high - speed rail freight, which is applied to the rapid loading and unloading device for high - speed rail freight in the above - mentioned embodiment, and includes: before the high - speed rail arrives at the station, receiving the car body model and cargo information, and generating a loading and unloading path plan; scanning the door height of the high - speed rail car and adjusting the lifting height of the mobile loading and unloading platform; positioning and inserting the cargo box in the car through the forklift mechanism, and transferring it to the platform area; after the cargo boxes in the platform area are sorted, loading them back into the high - speed rail car in the reverse direction; moving the cargo box into the storage compartment in the high - speed rail car, and resetting the equipment after the loading and unloading is completed.

[0012] According to an embodiment of the present invention, the step of scanning the door height of the high - speed rail car and adjusting the lifting height of the mobile loading and unloading platform includes: setting the initial lifting height of the mobile loading and unloading platform based on the pre - stored vehicle model parameters; dynamically correcting the actual lifting height by real - time scanning of the door height data of the high - speed rail car.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0025] The present invention belongs to the cross - field of rail transit freight equipment and logistics automation, and specifically relates to a high - speed rail freight rapid loading and unloading device and method suitable for high - speed rail freight. The aim is to overcome the bottlenecks of the existing technology in terms of efficiency, compatibility, cost, and intermodal transportation through an intelligent, flexible, and standardized loading and unloading solution. The system includes the transformation of the carriage structure, dedicated rapid loading and unloading mechanisms (such as modular conveyors, movable lifting platforms, forklifts, and circular conveyors), the design of transfer boxes, and intermodal transportation interface technology, achieving the standardized connection between high - speed rail and road / air freight. In addition, the intelligent loading and unloading system can integrate automated control and algorithms for cargo positioning and loading optimization, meeting the rapid transfer requirements of high - timeliness goods (such as fresh produce, pharmaceuticals, and express deliveries), and efficiently completing the loading and unloading operations within the short time (usually 3 - 5 minutes) when the high - speed rail stops at the station. By integrating these advanced technologies and equipment, the present invention provides an efficient, flexible, and standardized solution, providing strong technical support for the efficient transfer of goods between high - speed rail carriages and platforms, and meeting the strict requirements of modern logistics for high timeliness.

[0026] The following will describe the specific implementation manners of the high - speed rail freight rapid loading and unloading device of the present invention in conjunction with Figure 1 , Figure 2 and Figure 3 .

[0027] The present invention provides a high - speed rail freight rapid loading and unloading device, including: a modular conveyor 10, arranged in the platform area, including a sorting section 11 for outputting cargo boxes; a mobile loading and unloading platform 20, capable of moving between the platform area and the high - speed rail carriage 30. The mobile loading and unloading platform 20 is provided with the following devices: a forklift mechanism 21 for inserting and picking up cargo boxes; a hydraulic lifting column 22 for adjusting the height of the mobile loading and unloading platform 20; a horizontal rotating chassis 23, arranged between the mobile loading and unloading platform 20 and the forklift mechanism 21, for adjusting the horizontal orientation of the forklift mechanism 21; a positioning component for positioning the positions of the cargo box and the high - speed rail carriage 30 relative to the mobile loading and unloading platform 20; and an intelligent control terminal 24, which establishes communication connections with the modular conveyor 10 and each device of the mobile loading and unloading platform 20.

[0028] The device realizes the efficient transfer of goods between the platform and the high - speed rail carriage 30 through modular design. The modular conveyor 10 can effectively sort the goods to be loaded to the platform area as required. The mobile loading and unloading platform 20, with its equipped forklift mechanism 21, hydraulic lifting column 22, and horizontal rotating chassis 23, realizes the precise operation of goods at different heights and positions. In addition, the positioning component ensures the precise docking between the cargo box and the high - speed rail carriage 30, improving the accuracy and efficiency of the loading and unloading operations. The entire system is uniformly managed by the intelligent control terminal 24. Through real - time monitoring and data analysis, the loading and unloading path and process of the goods are optimized, improving the work efficiency.

[0029] Preferably, before the arrival of the high-speed train, the above-mentioned rapid loading and unloading device for high-speed rail freight first generates a detailed loading and unloading path plan based on the received car body model and cargo information, and automatically adjusts the height of the mobile loading and unloading platform 20 to match the height of the door of the high-speed rail car body 30. When the train stops, the mobile loading and unloading platform 20 quickly approaches the car body, precisely inserts and picks up the cargo box by using the forklift mechanism 21, and through the coordinated operation of the hydraulic lifting column 22 and the horizontal rotating chassis 23, smoothly transfers the cargo to the modular conveyor 10 on the platform. Conversely, during loading, the modular conveyor 10 will send the cargo to the designated position in the sorting section 11, and then the mobile loading and unloading platform 20 will transfer the cargo into the high-speed rail car body 30. The whole process makes full use of the short stop time of the high-speed train (usually 3 - 5 minutes), improving the transportation efficiency of high-timeliness goods.

[0030] According to the above embodiment, the present invention provides a rapid loading and unloading device for high-speed rail freight. Through the coordinated operation of the modular conveyor 10, the mobile loading and unloading platform 20, the forklift mechanism 21 and the intelligent control terminal 24, the contradiction between the short stop time of the high-speed train and the low loading and unloading efficiency is solved. Among them, the modular conveyor 10 is arranged in the open area of the platform and set longitudinally along the platform, which is used to realize the docking and sorting of external cargo boxes; the mobile loading and unloading platform 20 has the functions of moving forward and backward and adjusting the height up and down, and can flexibly approach the loading and unloading opening of the high-speed rail car body 30 for operation, and adapt to the hatch heights of different vehicle types through the hydraulic lifting column 22. The forklift mechanism 21 is used to insert or place standardized cargo boxes, and is equipped with a horizontal rotating chassis 23, which supports precise adjustment of height and angle to meet complex loading and unloading requirements. In addition, the intelligent control terminal 24 interacts with the high-speed rail dispatching center in real time through a wireless communication module, plans the cargo loading and unloading path in advance, and ensures the high-efficiency and orderly of the whole loading and unloading process.

[0031] To address the problem that the existing loading and unloading methods (such as manual handling, small forklifts) cannot complete the loading and unloading of a large number of goods within the 3 - 5 minutes of the high-speed train stop time, the present invention adopts a coordinated operation mode of a conveyor, a mobile loading and unloading platform 20, a forklift mechanism 21 and a loop conveyor, realizing the full-automatic rapid transfer from the platform to the car body, and shortening the single loading and unloading time to within 2 minutes. In addition, aiming at the problem of poor adaptability of existing automation equipment (such as fixed conveyors, automated guided vehicles (AGVs)), the present invention breaks through the compatibility limitations through the design of the modular conveyor 10 and the intelligent mobile loading and unloading platform 20. The modular conveyor 10 can arrange the cargo boxes to be transferred to the sorting section 11 in advance according to the loading and unloading requirements, while the intelligent mobile loading and unloading platform 20 dynamically matches the hatch heights of different vehicle types (such as a ±200 mm adjustment range can be set) and the platform gap through the positioning component and the hydraulic lifting system, so as to adapt to a variety of high-speed rail vehicle types (such as multiple unit trains, freight multiple unit trains) and platform conditions, greatly improving the flexibility and applicability of the loading and unloading system.

[0032] Furthermore, a high-speed rail freight rapid loading and unloading device according to the present invention, the hydraulic lifting column 22 is arranged at the bottom of the mobile loading and unloading platform 20, having a vertical stroke adjustment range of ±200 mm; the rotating chassis 23 is arranged on the mobile loading and unloading platform 20, and the fork mechanism 21 is arranged on the rotating chassis 23; the positioning component includes: an infrared sensor 25 for positioning the insertion and extraction position of the cargo box; a laser rangefinder 26 for positioning the loading and unloading position of the high-speed rail carriage 30. Through the collaborative control method, this high-speed rail freight rapid loading and unloading device can efficiently complete the precise insertion and placement of the cargo box, solve the docking problem caused by the differences in high-speed rail vehicle models, and significantly improve the loading and unloading efficiency and compatibility.

[0033] Among them, the hydraulic lifting column 22 is arranged at the bottom of the mobile loading and unloading platform 20. Through the vertical stroke adjustment range of ±200 mm, it can flexibly adapt to the hatch heights of different vehicle models, ensuring that the fork mechanism 21 can accurately operate under different height conditions. The rotating chassis 23 is installed on the mobile loading and unloading platform 20, and the fork mechanism 21 is fixed on the rotating chassis 23. By means of the horizontal rotation function, the lateral deviation between the carriage and the platform is compensated, so as to realize the precise adjustment of the cargo box position. The positioning component further enhances the accuracy of the system. Among them, the infrared sensor 25 can be equipped at the end of the fork mechanism 21 to detect the insertion and extraction position of the cargo box in real time, ensuring that the fork mechanism 21 can accurately insert or place the cargo box; the laser rangefinder 26 can be used to scan the position information of the door of the high-speed rail carriage 30 and transmit the data to the intelligent control terminal 24. The intelligent control terminal 24 integrates laser ranging, visual recognition and scheduling algorithms, comprehensively analyzes the carriage position and cargo distribution, calculates the optimal loading and unloading path, and coordinates the multi-degree-of-freedom movements of the mobile loading and unloading platform 20, the hydraulic lifting column 22 and the fork mechanism 21.

[0034] Furthermore, a high-speed rail freight rapid loading and unloading device according to the present invention, an annular conveyor line is arranged inside the high-speed rail carriage 30. The annular conveyor line includes: a chain conveyor 31 arranged along the length direction of the high-speed rail carriage 30; roller lifting and transplanting machines 32 arranged at both ends of the chain conveyor 31, jointly forming an annular conveyor line with two parallel chain conveyors 31; the roller lifting and transplanting machines 32 have an operating state higher than that of the chain conveyor 31 and a hidden state lower than that of the chain conveyor 31; a plurality of electromagnetic locking devices are arranged in the high-speed rail carriage 30 for fixing the position of the cargo box in the high-speed rail carriage 30.

[0035] Specifically, a circular conveyor line is provided inside the high-speed rail carriage 30, and the circular conveyor line includes a chain conveyor 31 and a roller lifting and transplanting machine 32. The chain conveyor 31 is arranged along the length direction of the high-speed rail carriage 30, and is used to efficiently transport cargo boxes in the carriage; the roller lifting and transplanting machine 32 is arranged at both ends of the chain conveyor 31, and together with the two parallel chain conveyors 31, forms a closed circular conveyor line system. This design allows the roller lifting and transplanting machine 32 to switch between an operating state higher than the chain conveyor 31 and a hidden state lower than the chain conveyor 31, so as to transfer cargo boxes from one chain conveyor 31 to another when needed, or to avoid interfering with other operations when not in use.

[0036] In addition, in order to ensure the stability of the cargo box during transportation, a number of electromagnetic locking devices are set in the high-speed rail car 30, which can lock the cargo box after it is placed in the specified position to prevent it from moving during the train. The fork mechanism 21 has a lateral telescopic function and can extend to the docking end of the modular conveyor 10 and the docking end of the circular conveyor line inside the car, thereby achieving seamless docking of the cargo box. In this way, the cargo box can be directly transferred from the modular conveyor 10 on the platform to the circular conveyor line inside the high-speed rail car 30, or reversely operated to complete an efficient cargo loading and unloading process.

[0037] According to the high-speed railway freight rapid loading and unloading device of the preferred embodiment of the present invention, the mobile loading and unloading platform 20 and the fork mechanism 21 accurately place the cargo box on the chain conveyor 31 at the large-opening loading door 33 of the high-speed railway carriage 30, and then the cargo box runs along the chain conveyor 31 to the end and stops steadily; at this time, the roller lifting and transplanting machine 32 rises from a low position to a high position, lifts the cargo box and moves it to the end in a direction perpendicular to the chain conveyor 31, and then drops to a low position after stopping steadily again, and puts the cargo box back on the chain conveyor 31; the chain conveyor 31 is then started, driving the cargo box to move forward in the direction of the chain machine, thereby realizing the circular movement of the cargo box in the high-speed railway carriage 30. Through the coordinated work of the roller lifting and transplanting machine 32 and the chain conveyor 31, the problem of multi-directional transmission of goods is solved, ensuring the smooth and efficient loading and unloading process. At the same time, combined with the scheduling algorithm of the intelligent control terminal 24, the cargo transportation path is optimized, and the loading and unloading efficiency is significantly improved, which is suitable for the rapid transportation needs of high-timeliness goods.

[0038] Further, according to a high-speed rail freight rapid loading and unloading device of the present invention, the cargo box is preferably a standard transfer cargo box 40; the bottom of the standard transfer cargo box 40 has a mechanical insertion slot adapted to the fork mechanism 21. Specifically, in order to make up for the loading and unloading bottleneck caused by insufficient cargo standardization, a lightweight standard transfer cargo box 40 is introduced. The bottom of the standard transfer cargo box 40 is designed with a mechanical insertion slot adapted to the fork mechanism 21, ensuring that the fork can stably and accurately perform the insertion and placement operations of the cargo box.

[0039] The standard transfer container 40 is preferably made of honeycomb aluminum composite material, which is not only lightweight but also has high strength and excellent durability, helping to reduce the risk of cargo damage during transportation. The container can be folded when not in use, and its volume can be reduced by 60%, greatly saving storage and return transportation space.

[0040] In addition, RFID tags can preferably be embedded in the bottom of the standard transfer container 40, which not only facilitates cargo tracking and management but also enables real-time monitoring of the location and status of the cargo through the intelligent control terminal 24, improving the transparency and efficiency of logistics management. Uniformly sized insertion slots are provided at the bottom of each standard transfer container 40, and these slots are designed to match the forklift mechanism 21 to ensure the stability and consistency of operations during loading and unloading.

[0041] Furthermore, according to a high-speed rail freight rapid loading and unloading device of the present invention, the modular conveyor 10 includes: a straight section 12, which includes a plurality of linearly connected conveyor modules for transporting the container to the corresponding platform area; a turning section 13, provided at the end of the straight section 12, which includes a roller lifting and transplanting module with a conveying direction perpendicular to that of the linear conveyor module; and a sorting section 11 connected to the turning section 13, which includes a plurality of linearly connected conveyor modules for successively parking a plurality of containers.

[0042] Among them, the straight section 12 is composed of a plurality of linearly connected conveyor modules that can seamlessly transport the container from one position to another until it reaches the designated platform area.

[0043] The turning section 13 is provided at the end of the straight section 12 and includes a roller lifting and transplanting module with a conveying direction perpendicular to that of the linear conveyor module. This design enables the container to make a smooth transition between the straight section 12 and the sorting section 11, ensuring continuous transmission of the cargo in different directions and increasing the flexibility and adaptability of the system.

[0044] The sorting section 11 is connected to the turning section 13 and is also composed of a plurality of linearly connected conveyor modules, but its special feature is that it supports multi-channel parallel operation. The sorting section 11 can process multiple containers simultaneously and successively park them at predetermined positions for subsequent loading and unloading operations. In this way, even when facing high-timeliness cargo loading and unloading tasks (such as fresh produce, pharmaceuticals, express delivery, etc.), the work efficiency can be significantly improved and the waiting time can be reduced.

[0045] Based on the above inventive concept, this solution can also achieve seamless multimodal transportation connections among high-speed rail, road, and aviation. Existing loading and unloading technologies usually do not consider the interface design with other transportation modes, resulting in low efficiency and complex operations during the transfer process. To solve this problem, the present invention can be extended to design a standardized loading and unloading interface in the platform area, supporting the direct loading and unloading of transfer containers between trucks, drones, and the high-speed rail conveying system, thereby significantly reducing the intermediate handling links and improving the transfer efficiency. In addition, by equipping the cargo containers with Internet of Things (IoT) tags, the flow of the cargo containers can be tracked in real time, and combined with the linkage dispatching system, the loading and unloading resources can be automatically allocated, further optimizing the overall process of multimodal transportation and achieving efficient and intelligent logistics connections.

[0046] To further enhance the coverage and technical universality of the high-speed rail freight rapid loading and unloading device of the present invention, the following extensions can also be made.

[0047] For example, in the drone / AGV collaborative loading and unloading system, by deploying an automatic guided vehicle (AGV) or a drone connection system at the high-speed rail platform and seamlessly connecting with the conveyor, "last-mile" automated transfer is achieved. The AGV is equipped with a visual navigation system, capable of automatically picking up goods from the truck unloading area and delivering them to the entrance of the high-speed rail conveyor; the drone is used for the rapid delivery of urgent small items (such as medical samples). This design is suitable for small high-speed rail stations without dedicated freight platforms, especially for high-time-efficiency logistics requirements, such as pharmaceutical cold chain and emergency material transportation. In addition, the AI dynamic loading and unloading optimization system integrates a deep learning model into the intelligent control terminal 24 to analyze the cargo distribution and the utilization rate of the carriage space in real time, thereby optimizing the loading and unloading sequence. For example, perishable goods are preferentially loaded or the stacking method of the cargo containers is adjusted according to the destination to maximize the loading rate and reduce the empty return situation, which is suitable for large-scale e-commerce express transportation or multi-destination multimodal transportation scenarios.

[0048] For the transportation requirements of special goods (such as artworks, industrial parts), a deformable cargo container combined with a robotic arm flexible grasping technology can also be adopted. The cargo container uses variable stiffness materials (such as shape memory alloys), maintaining rigidity during transportation and being able to flexibly deform during loading and unloading to adapt to narrow spaces. This not only increases the compatibility of cargo types but also reduces the strict restrictions on the standardized cargo container size, making the handling of complex goods more flexible and efficient. Combining with the intelligent control terminal 24 and the fork mechanism 21 in the present invention, these special goods can be loaded and unloaded more accurately, improving the overall efficiency and safety.

[0049] In addition, to meet different application scenarios and technical requirements, several alternative solutions have been proposed. For example, the maglev conveying system uses magnetic fields to suspend and move the permanent magnets embedded in the bottom of the cargo box, reducing frictional resistance and energy consumption. Although the initial cost is relatively high and platform modification is required, its low-noise characteristic is suitable for night operations. It is also possible to directly enter the interior of the carriage for loading and unloading operations by using a collaborative robot (CoBot) with a lightweight robotic arm equipped with an adaptive fixture, providing higher flexibility and the ability to handle complex cargo stacks. Finally, a pneumatic adsorption loading and unloading system can be adopted to grab the vacuum adsorption interface on the surface of the cargo box through a negative pressure suction cup, avoiding the risk of mechanical collision and being suitable for handling fragile items. These alternative solutions can all be seamlessly integrated with the existing modular conveyor 10 and intelligent control terminal 24 to provide more diverse loading and unloading solutions.

[0050] The present invention also provides a high-speed rail freight rapid loading and unloading method, which is applied to the high-speed rail freight rapid loading and unloading device in the above-mentioned embodiment. The high-speed rail freight rapid loading and unloading method provided by the present invention will be described below. The high-speed rail freight rapid loading and unloading method described below can be mutually corresponded and referred to the high-speed rail freight rapid loading and unloading device described above.

[0051] Figure 4 It is a schematic flow chart of the high-speed rail freight rapid loading and unloading method provided by the present invention. As Figure 4 shown, the method includes the following: Step 110: Before the high-speed rail arrives at the station, receive the carriage model and cargo information, and generate a loading and unloading path plan. The intelligent control terminal 24 obtains the model of the upcoming high-speed rail carriage 30 and the detailed information of the cargo to be loaded and unloaded (such as cargo type, size, weight, etc.) from the high-speed rail dispatching center through the wireless communication module. Based on this information, the intelligent control terminal 24 uses the built-in optimization algorithm to generate a detailed loading and unloading path plan to ensure that the cargo can be loaded and unloaded efficiently and orderly.

[0052] Step 120: Scan the height of the door of the high-speed rail carriage 30 and adjust the lifting height of the mobile loading and unloading platform 20. When the high-speed rail train stops, the laser rangefinder 26 scans the height of the door of the high-speed rail carriage 30 in real time and transmits the data to the intelligent control terminal 24. According to the received data, the intelligent control terminal 24 commands the hydraulic lifting column 22 to adjust the height of the mobile loading and unloading platform 20 to accurately match the height of the carriage door, ensuring that the forklift mechanism 21 can smoothly enter the carriage for operation.

[0053] Step 130: Locate and insert the cargo box in the carriage through the forklift mechanism 21, and transfer it to the platform area. The positioning component accurately locates the position of the cargo box and guides the forklift mechanism 21 to accurately insert into the mechanical insertion slot at the bottom of the cargo box. Subsequently, the forklift mechanism 21 smoothly lifts the cargo box and safely transfers it to the modular conveyor 10 on the platform through the mobile loading and unloading platform 20, preparing for further sorting or transportation.

[0054] Step 140: After the freight containers in the platform area are sorted, they are reversely loaded into the high-speed rail carriage 30. The modular conveyor 10 in the platform area sorts and temporarily stores freight containers with different destinations or types according to a preset sorting logic. When loading is required, the freight containers are accurately placed back into the predetermined positions in the high-speed rail carriage 30 through the mobile loading and unloading platform 20 and the forklift mechanism 21 to achieve an efficient reverse loading process.

[0055] Step 150: Move the freight containers into the storage compartments in the high-speed rail carriage 30, and reset the equipment after loading and unloading. After all the freight containers are successfully transported to the designated storage compartments in the carriage, the intelligent control terminal 24 issues commands to reset all the equipment, including moving the mobile loading and unloading platform 20 back to the initial position, restoring the hydraulic lifting column 22 to the default height, and returning the forklift mechanism 21 to the starting state to prepare for the next loading and unloading task.

[0056] Further, in a method for rapid loading and unloading of high-speed rail freight according to the present invention, the steps of scanning the door height of the high-speed rail carriage 30 and adjusting the lifting height of the mobile loading and unloading platform 20 include: Step 121: Set the initial lifting height of the mobile loading and unloading platform 20 based on pre-stored vehicle model parameters. Before the high-speed rail arrives at the station, the intelligent control terminal 24 retrieves the standard parameters (such as the carriage door height) of the corresponding vehicle model from the pre-stored vehicle model database according to the received carriage model information. Based on these standard parameters, the system pre-sets the initial lifting height of the mobile loading and unloading platform 20 to ensure that when the high-speed rail arrives, the height of the mobile loading and unloading platform 20 generally meets the requirements of the target carriage. This preset mechanism can significantly reduce the adjustment time during actual operation and improve the overall loading and unloading efficiency.

[0057] Step 122: Dynamically correct the actual lifting height by real-time scanning of the door height data of the high-speed rail carriage 30. When the high-speed rail train stops, the laser rangefinder 26 or other high-precision measuring devices perform real-time scanning of the actual door height of the high-speed rail carriage 30, and transmit the obtained data to the intelligent control terminal 24. The intelligent control terminal 24 compares the pre-stored vehicle model parameters with the actual measurement data, calculates the specific value that needs to be adjusted. Subsequently, the control system commands the hydraulic lifting column 22 to precisely adjust the height of the mobile loading and unloading platform 20 to achieve the best matching state. This dynamic correction process not only compensates for the dimensional differences caused by manufacturing tolerances or wear, but also adapts to the minor changes under different environmental conditions, ensuring that the forklift mechanism 21 can smoothly and accurately enter the carriage for cargo loading and unloading operations.

[0058] Further, in a method for rapid loading and unloading of high-speed rail freight according to the present invention, the steps of positioning and inserting the freight containers in the carriage through the forklift mechanism 21 and transferring them to the platform area include: Step 131: Use the infrared sensor 25 to detect the horizontal position deviation of the container insertion slot. When preparing to insert the container, the infrared sensor 25 is installed at the end of the forklift mechanism 21 and is used to detect the precise position of the mechanical insertion slot at the bottom of the container in real time. By scanning the space around the container, the infrared sensor 25 can identify the actual horizontal position of the container relative to the forklift mechanism 21 and calculate the horizontal position deviation, providing a basis for subsequent precise adjustment.

[0059] Step 132: Control the horizontal rotation of the forklift mechanism 21 to compensate for the horizontal position deviation. According to the position deviation data obtained in Step 131, the intelligent control terminal 24 sends an instruction to the horizontal rotation chassis 23, which is arranged between the mobile loading and unloading platform 20 and the forklift mechanism 21. The horizontal rotation chassis 23 precisely adjusts the horizontal orientation of the forklift mechanism 21 according to the received instruction to compensate for the detected horizontal position deviation. This process ensures that the forklift mechanism 21 can accurately insert into the mechanical insertion slot at the bottom of the container, enabling smooth and precise insertion operations even in the presence of minor deviations. Through this adaptive adjustment mechanism, the system not only improves the success rate of container insertion but also reduces the time wasted due to manual adjustment or repositioning, thus significantly enhancing the efficiency and reliability of the entire loading and unloading process.

[0060] Furthermore, according to a high-speed rail freight rapid loading and unloading method of the present invention, the steps of reversely loading the sorted containers in the platform area into the high-speed rail carriage 30 include: Step 141: Automatically assign sorting sections 11 according to the destination codes of the containers during loading. Before the goods are prepared for reloading, each standard transfer container 40 has been pre-assigned a destination code, which can be read through RFID tags or other identification technologies. When the containers arrive in the platform area, the modular conveyor 10 system first guides these containers to the sorting sections 11. The intelligent control terminal 24 automatically generates an optimal sorting path through an algorithm according to the destination code of each container and automatically assigns the corresponding sorting section 11.

[0061] During the sorting process, the sensors on the modular conveyor 10 will read the RFID tags or barcodes on each container to identify its destination code. Based on this information, the control system dynamically adjusts the working states of each section of the conveyor to ensure that the containers are accurately conveyed to the sorting section 11 corresponding to the destination. For example, if a container is destined for City A, it will be automatically assigned to the sorting section 11 corresponding to City A; while another container destined for City B will be assigned to another path, and so on. This automated sorting and distribution mechanism not only improves the operation efficiency but also reduces the possibility of human errors, ensuring that the goods can be loaded onto the vehicle as planned and sent to the correct destination.

[0062] Furthermore, in a rapid loading and unloading method for high-speed rail freight according to the present invention, the steps of moving the cargo box into the storage compartment in the high-speed rail carriage 30 and resetting the equipment after loading and unloading include: Step 151: Move the cargo box into the high-speed rail carriage 30. Specifically, after being sorted and redistributed in the platform area, the cargo box is precisely lifted and transferred to the opening of the large-opening loading door 33 of the high-speed rail carriage 30 through the mobile loading and unloading platform 20 and the forklift mechanism 21. The intelligent control terminal 24 coordinates the hydraulic lifting column 22 to adjust the height of the mobile loading and unloading platform 20 to ensure that the height of the forklift mechanism 21 precisely matches the height of the carriage door. Then, the forklift mechanism 21 smoothly removes the cargo box from the modular conveyor 10 and safely moves it into the high-speed rail carriage 30 for the next placement operation.

[0063] Step 152: Move the cargo box to the corresponding storage compartment through the loop conveyor line in the high-speed rail carriage 30. Once the cargo box enters the high-speed rail carriage 30, it is placed on the chain conveyor 31. According to the optimal path and storage compartment arrangement pre-calculated by the intelligent control terminal 24, the chain conveyor 31 is activated to drive the cargo box to move forward in a predetermined direction.

[0064] Step 153: Activate the electromagnetic locking device to fix the position of the cargo box. When the cargo box is moved to its designated storage compartment, multiple electromagnetic locking devices arranged in the carriage are activated. The electromagnetic locking device automatically locks the cargo box to ensure that it does not shift or topple during the train operation.

[0065] Preferably, each electromagnetic locking device is connected to the intelligent control system and can automatically adjust the locking force according to the specific size and weight of the cargo box, so as to provide the most suitable fixing effect. In addition, the intelligent control terminal 24 preferably also records the storage position of each cargo box and its locking state, so as to quickly locate and unlock the cargo box during subsequent unloading, ensuring the efficiency and safety of the entire loading and unloading process.

[0066] According to the high-speed rail freight rapid loading and unloading method of the preferred embodiment of the present invention, in the system initialization stage, before the high-speed rail arrives at the station, the intelligent control terminal 24 receives the car body model and cargo list information, and plans the loading and unloading path; the mobile loading and unloading platform 20 drives the hydraulic lifting column 22 and the forklift mechanism 21 to lift to the estimated height and standby, preparing for the loading and unloading operation. During the process of inserting, picking up and transporting the cargo box, the forklift mechanism 21 extends into the large-opening loading door 33 of the high-speed rail car body 30, accurately locates the position of the standard transfer cargo box 40 through the infrared sensor 25, retracts after picking up and places the cargo box on the modular conveyor 10, and sorts it to the corresponding receiving area according to the destination. Then, in the reverse loading step, the cargo box enters the conveyor system through the straight section 12, and then the forklift mechanism 21 sends the cargo box back to the ring conveyor (RGV) in the car body, and moves to the fixed storage position according to the information guidance of the intelligent control terminal 24. After the intelligent control terminal 24 confirms the completion of the loading and unloading task, it will feedback the relevant information to the high-speed rail signal system and close the large-opening loading door 33. Finally, in the data synchronization and reset stage, the system uploads the operation log to the cloud, and at the same time the modular conveyor 10, the mobile loading and unloading platform 20 and the forklift mechanism 21 are all reset to the standby state to ensure that the equipment is ready for the next operation. This series of steps realizes an efficient, automated and accurate high-speed rail freight loading and unloading process.

[0067] In view of the existing technical defects in high-speed rail freight loading and unloading, the present invention proposes a set of high-efficiency, intelligent and flexible adaptation high-speed rail freight rapid loading and unloading device and method, which has the following remarkable advantages: First, through the coordinated operation of the modular conveyor 10, the mobile loading and unloading platform 20, the forklift mechanism 21 and the ring conveyor, and the parallel loading and unloading channel design, the single loading and unloading time is greatly shortened, the efficiency is significantly improved compared with the traditional manual handling, and it supports the synchronous transfer of multiple cargo boxes (such as 4 channels in parallel), meeting the high-frequency freight demand within the short stop time of high-speed rail. Second, the system has a high degree of automation and reduces manual intervention. The intelligent control terminal 24 integrates an infrared sensor 25, a laser rangefinder 26 and an optimized scheduling algorithm, realizing the full-process automated operation from positioning, picking up to conveying and sorting, reducing the manual participation degree and the delay risk caused by sorting errors.

[0068] Furthermore, the equipment has strong compatibility and can adapt to mainstream high-speed rail models such as CRH and Fuxinghao, covering more than 90% of freight scenarios; the mobile loading and unloading platform 20 combines with the forklift mechanism 21 and the horizontal rotating chassis 23 to dynamically compensate for the platform gap and solve the docking deviation problem caused by track tolerance. Finally, the standardized cargo box design improves the logistics coordination efficiency. The standard transfer cargo box 40 is not only lighter than the traditional metal container, meets the high-speed rail axle load limit, but also has a reduced volume after folding, reducing the cost of empty box return transportation; the built-in temperature control module ensures full-course temperature control of cold-chain goods, and the loss rate of medicines / fresh products decreases; and it is linked with the cloud scheduling system to achieve full-course visual tracking of goods. This series of innovations provides an efficient, flexible and reliable solution for high-speed rail freight, significantly improving the service quality and efficiency of the modern logistics system.
