Description

Technical Field

[0001] The present invention relates to the technology of combined rail and road transportation logistics. More specifically, it relates to a railway gantry crane loading and unloading system and method for improving the efficiency of combined rail and road transportation. Background Art

[0002] With the rapid development of the global logistics network, combined rail and road transportation, as an efficient and environmentally friendly transportation mode, has become increasingly important. However, the equipment used in existing combined rail and road transportation loading and unloading systems is usually a conventional railway gantry crane, which still has many deficiencies in terms of efficiency, flexibility, and safety, and is difficult to meet the needs of modern logistics. The main deficiencies are as follows:

[0003] 1) In the existing system, the spreader of the railway gantry crane frequently moves in the trolley direction. Usually, it can only rely on the micro-motion function of the trolley or the spreader upper frame to achieve small-range position adjustment of the spreader in the trolley direction. When a large-range position adjustment is required along the trolley direction, it is necessary to drive the trolley to move the whole machine to complete. This operation method not only has low accuracy, high technical requirements for operators, but also causes unnecessary energy consumption, and may also lead to inaccurate positioning in the trolley direction, thus prolonging the loading and unloading cycle and further affecting the loading and unloading efficiency.

[0004] 2) In the existing system, the external road vehicles and internal vehicles driving on the same plane are prone to traffic congestion, affecting the overall operation efficiency and safety. In the technical field of terminal transportation facilities, some loading and unloading systems have adopted elevated road designs. For example, in the published patent "A Three-dimensional Traffic Loading and Unloading Process for a Container Yard" (application publication number CN109941767 A) and the authorized patent "Port Container Three-dimensional Operation System" (authorization announcement number CN 214454476 U), a solution to separate the paths of external road vehicles and internal vehicles through elevated roads is proposed, effectively solving the traffic conflict problem in the port yard. However, in the scenario of combined rail and road transportation, the interaction between railway and road transportation is more complex, and the existing solutions are difficult to be directly applied. There is an urgent need for a three-dimensional traffic system adapted to railway gantry crane loading and unloading.

[0005] 3) The existing system lacks efficient intelligent scheduling capabilities and relies on manual operations to complete task allocation and path planning, which is not only inefficient but also prone to human errors, increasing the operating costs. Summary of the Invention

[0054] In order to better understand the above technical solutions of the present invention, the technical solutions of the present invention will be further described below with reference to the drawings and embodiments.

[0055] Combined with Figures 1 to 6 as shown, a railway gantry crane loading and unloading system for improving the efficiency of rail-road intermodal transportation provided by the present invention includes:

[0056] A railway gantry crane 10 for loading and unloading goods on a railway loading and unloading line 20.

[0057] The railway gantry crane 10 adopts a double-cantilever design, and the two cantilevers respectively correspond to the loading and unloading tracks on both sides of the railway loading and unloading line 20, and can simultaneously handle different types of horizontal transportation vehicles (external road vehicles 80 and internal ground vehicles 90) on both sides.

[0058] The span of the railway gantry crane 10 is one or more railway tracks, and the span matches the scale of the main container yard 30 and the number and layout form of the railway loading and unloading lines 20.

[0059] The spreader on the railway gantry crane 10 can be replaced according to the type of goods, and supports the loading and unloading of various forms of goods such as containers and bulk goods.

[0060] The trolley assembly on the railway gantry crane 10 includes a transverse trolley 11, a longitudinal trolley 12, a slewing trolley 13 and a hoisting mechanism 14.

[0061] The transverse trolley 11 is located on the upper surface of the main structure of the railway gantry crane 10 and can move back and forth in the direction perpendicular to the longitudinal direction of the trolley 15, so as to achieve precise positioning in the transverse direction.

[0062] The longitudinal movement trolley 12 is installed on the transverse movement trolley 11 and runs along the longitudinal movement track in the same direction as the longitudinal movement direction of the gantry 15. The longitudinal movement trolley 12 can achieve long-distance longitudinal reciprocating movement along the direction of the gantry 15, covering at least the length of one standard car body. This design is optimized by reducing the frequent overall movement of the gantry caused by the lack of a longitudinal movement trolley in a conventional rail crane and relying on the fine movement function of the spreader system itself to operate within a limited stroke. This not only improves work efficiency but also reduces energy consumption and mechanical wear caused by the frequent movement of the gantry. The optimized rail crane loading and unloading system of the present invention can perform more precise position adjustment, thereby providing more stable and efficient cargo handling capabilities. In addition, it helps to reduce operation time and improve the smoothness and efficiency of the entire loading and unloading process.

[0063] The slewing trolley 13 is arranged on the longitudinal movement trolley 12 and can freely slewing on a circular track to meet the horizontal rotation requirements of the spreader. The slewing function of the slewing trolley 13 can also be realized by configuring a corresponding slewing mechanism for the spreader.

[0064] The hoisting mechanism 14 is fixed on the slewing trolley 13 to assist the spreader in lifting and lowering movements in the vertical direction.

[0065] Through the coordinated work of the components in the trolley assembly, the multi-functional trolley assembly realizes the all-round movement ability of the spreader in the transverse, longitudinal, vertical, and horizontal slewing directions. This not only greatly improves the loading and unloading operation efficiency and flexibility of the rail crane 10 but also enables the rail crane loading and unloading system of the present invention to perform diverse operation tasks in a more complex loading and unloading environment.

[0066] The railway loading and unloading line 20, each bundle line contains at least one railway loading and unloading line 20, is arranged between the rails of the rail crane 10 for train docking and cargo loading and unloading;

[0067] The reasonable length of the railway loading and unloading line 20 is determined by factors such as the yard layout and the number of cars loaded and unloaded at one time.

[0068] The elevated road 50 provides a passage for external road vehicles 80, and is spatially separated from the ground operation area of the rail crane 10 through a grade separation structure to avoid traffic conflicts between external road vehicles 80 and internal ground vehicles 90.

[0069] The elevated road 50 is located on one side of the upper boom of the rail crane 10, including at least one traffic lane 51 and one loading and unloading lane 52. The loading and unloading lane 52 is within the operation range of the boom on this side of the rail crane 10, and the effective length of the loading and unloading lane 52 matches the length of the railway loading and unloading line 20 to ensure that external road vehicles 80 can complete the loading and unloading of the entire train of goods without segmented operation.

[0070] One end of the elevated road 50 is provided with an entrance gate 110, and the other end is provided with an exit gate 120, which are used to control the entry and exit of external highway vehicles 80 to and from the elevated road 30. Among them, the entrance gate 110 and the exit gate 120 are designed to avoid direct interference with the operation of the railway gantry crane loading and unloading system of the present invention.

[0071] Safety protection devices are provided on the sides of the elevated road 50 to ensure the safety of the operators and equipment in the area of the lower railway loading line 20 during the driving and loading / unloading processes of the external highway vehicles 80.

[0072] A weighing device is provided on the elevated road 50 to monitor the weight of the passing vehicles and their loads in real time, so as to ensure the structural safety of the elevated road 50.

[0073] The ground road 60 provides a passage for the internal ground vehicles 90 and connects the main container yard 30 and the auxiliary container yard 40 through the ground road 60. The ground road 60 provided on the other cantilever side of the railway gantry crane 10 is also divided into a traffic lane 61 and a loading / unloading lane 62, including at least one traffic lane 61 and one loading / unloading lane 62, where the loading / unloading lane 60 is within the loading / unloading operation range under the other outer cantilever of the railway gantry crane 10.

[0074] The external highway vehicles 80 access the elevated road 50 via the external road 70 and drive along the elevated road 50 to one side of the railway gantry crane 10 for loading and unloading operations.

[0075] The internal ground vehicles 90 are not limited to manned vehicles, but can also be unmanned container carriers, AGVs or IGVs, etc., which are in-field horizontal transportation vehicles that do not require on-site control by a driver. The internal ground vehicles 90 drive along the ground road 60 to the other side of the railway gantry crane 10 for loading and unloading operations and are responsible for the container transfer between the main container yard 30 and the auxiliary container yard 40 through the ground road 60.

[0076] The main container yard 30 is arranged between the rails of the railway gantry crane 10 and directly serves the railway loading line 20, and is used to store goods that are about to be loaded and unloaded or need to be quickly transferred. Its scale is determined according to the span of the railway gantry crane 10, the number of railway loading lines 20 and the operation requirements.

[0077] The auxiliary container yard 40 is arranged outside the main container yard 30 and serves as a supplement to the main container yard 30. It is used to store goods that do not need to be loaded and unloaded temporarily or special types of goods (such as dangerous goods, refrigerated goods, etc.), and is connected to the main container yard 30 through the short-distance transfer and loading / unloading process of the internal ground vehicles 90. The loading / unloading equipment in the auxiliary container yard 40 can be suitable equipment such as a reach stacker, a railway gantry crane 10, etc.

[0078] An intelligent scheduling module, which is used to coordinate the resource allocation and task scheduling of the railway gantry crane 10, external road vehicles 80, internal ground vehicles 90, elevated roads 50, ground roads 60, main container yards 30 and auxiliary container yards 40.

[0079] The specific functions include:

[0080] 1) Intelligently plan the driving routes of external road vehicles 80 and internal ground vehicles 90 to reduce vehicle waiting time;

[0081] 2) Real-time monitor the status of the railway gantry crane 10, elevated roads 50, ground roads 60, main container yards 30 and auxiliary container yards 40 to ensure the smoothness of the loading and unloading process;

[0082] 3) Dynamically allocate loading and unloading tasks and optimize the operation sequence to improve the overall loading and unloading efficiency.

[0083] The railway gantry crane loading and unloading system of the present invention may also include other auxiliary facilities:

[0084] A vehicle identification device arranged on the road, which is used to automatically identify the identity information of vehicles.

[0085] A vehicle guiding device arranged on the road, which is used to guide vehicles into the designated loading and unloading area.

[0086] A data collection and analysis module, which collects and analyzes the operation data of the railway gantry crane loading and unloading system of the present invention to optimize the operation efficiency and maintenance plan.

[0087] An emergency response mechanism, which quickly starts the emergency plan in case of emergencies (such as equipment failures, traffic accidents, etc.) to ensure the safe operation of the system.

[0088] A remote monitoring platform, which conducts real-time monitoring and remote management of the operation status of the railway gantry crane loading and unloading system of the present invention.

[0089] An environmental monitoring device, which monitors environmental parameters such as dust and noise during the loading and unloading process and takes corresponding measures to reduce environmental pollution.

[0090] An energy recovery system, which recovers the excess energy generated by the railway gantry crane 10 and internal ground vehicles 90 during operation to achieve energy conservation and emission reduction.

[0091] An intermodal interface, which docks with other transportation modes (such as waterway, aviation, etc.) to achieve integrated logistics services.

[0092] Combined with Figures 1 to 7As shown in the figure, the present invention also provides a method for loading and unloading a railway gantry crane to improve the efficiency of combined rail and road transportation.
