Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of railway freight transfer equipment, specifically, it relates to a transfer box for railway freight. Background Technology
[0002] In the loading and unloading process of railway freight, efficient cargo transfer is key to improving overall efficiency. Currently, the common approach is to utilize transfer containers (wheeled carriages pulled by locomotives). Multiple transfer containers are linked together to form transport units, which circulate between the platform and cargo storage areas (such as warehouses or yards). These units are specifically responsible for moving goods awaiting loading from storage points to the train, or moving unloaded goods away from the train. This continuous operation mode aims to maximize equipment utilization and reduce the idle waiting time of locomotives and carriages.
[0003] However, most existing transshipment containers are designed too rudimentarily, consisting only of a simple container body and a walking mechanism. This primitive structure lacks effective internal assistance for loading and unloading heavy cargo, making the process laborious and time-consuming. It also makes seamless "door-to-door" unloading difficult, resulting in high labor intensity for personnel. Furthermore, for fragile goods such as precision instruments and ceramic products, there is a lack of necessary protective designs or dedicated partitions and limiting devices, significantly increasing the risk during handling and requiring operators to exercise extreme caution. All of these factors significantly slow down the flow of goods within the transshipment container.
[0004] Based on this, the present invention provides a transfer box for railway freight to solve the problems existing in the prior art. Utility Model Content

[0035] In a preferred embodiment, the bottom of the base plate is also provided with self-locking casters.
[0036] Compared with the prior art, this utility model provides a transfer box for railway freight, which has the following advantages:
[0037] 1. This transfer container achieves a significant improvement in transportation safety through a combination of a rigid frame and flexible mesh. The side protective frames, end protective plates, and bottom plate constitute an external rigid protection system. The end protective plates are rotatably connected to the uprights via a second pin, ensuring the integrity of the end protection while allowing for temporary openings by downward rotation. The upper end is locked using a pin-locking and L-shaped locking structure, ensuring the stability of the end protective plates during transportation. The horizontal and vertical frames of the partition protective plates, together with the protective mesh, form an internal flexible protective layer. The mesh absorbs the collision energy of the goods through elastic deformation. Combined with the external rigid frame, this creates a multi-layered protection from the outside in, effectively reducing the risk of displacement and damage to goods due to shaking.
[0038] 2. This transfer container features a rotating end guard plate design that allows for quick opening of the end inlet. Combined with the height adjustment function of the lifting plate, this significantly simplifies the loading and unloading process: rotating the eccentric wheel via the eccentric handle drives the transmission rod to rotate, which in turn adjusts the height of the lifting plate via the adjusting block and connecting rod, allowing the goods to be raised to a position close to the opening, reducing the bending or handling effort required by workers. Furthermore, the positioning rods and holes of the partition protection plate allow for quick internal space division without tools, greatly reducing operation time. These designs transform the complex fixing methods of traditional transfer containers into an adjustable and easy-to-operate mechanical structure, effectively improving loading and unloading efficiency and reducing manual labor intensity.
[0039] 3. This transfer container maximizes space utilization through its modular design. The horizontal and vertical frames of the partition protection panels can be adjusted along the sliding grooves to accommodate the partitioning needs of goods of different sizes. Combined with the lifting function of the lifting platform, it can meet the overall loading of large-volume goods, and also allow for the layered storage of small items by adjusting the lifting height and the position of the partition panels. This design allows the same transfer container to adapt to various types and sizes of goods, reducing the empty container rate caused by differences in goods specifications and improving the equipment utilization rate of railway freight. At the same time, the mesh structure of the protective net allows air circulation, avoiding the moisture problems that may occur in enclosed spaces, further enhancing its adaptability to the transportation environment. This solves the problems of current transfer containers lacking internal assistance loading and unloading facilities, making the loading and unloading process laborious and time-consuming, and making it difficult to achieve seamless "door-to-door" connection during unloading; as well as the easy damage to fragile goods during transportation and the impact on the flow rate.

[0053] Example 1
[0054] As per the instruction manual Figures 1-5 As shown, this utility model provides a technical solution:
[0055] A railway freight transfer container includes a base plate 1, which is a rectangular frame structure providing a supporting foundation. A continuous, detachable protective railing and a cargo lifting mechanism are installed on its upper side. The protective railing is located around the upper perimeter of the base plate 1, forming a continuous and adjustable protective system. The cargo lifting mechanism is located within the protective railing and is movably mounted on the base plate 1. The detachable protective railing protects the goods stored inside the transfer container, preventing them from falling during transport. The cargo lifting mechanism allows adjustment of the height of the goods inside the container, facilitating easy handling and loading / unloading. Self-locking casters 8 are also installed at the bottom of the base plate 1. This structure allows the transfer container to move flexibly, maximizing its proximity to railway freight cars for seamless door-to-door connection, improving cargo transfer efficiency. Simultaneously, the self-locking function of the casters 8 ensures the transfer container is stably fixed during loading, unloading, or parking, guaranteeing operational safety.
[0056] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the protective railing includes uprights 2, side protective frames 3, and positioning plates 5 mounted on a base plate 1. The uprights 2 are fixed to the four corners of the upper surface of the base plate 1, serving as the main mounting supports. The side protective frames 3 are detachably connected between two adjacent uprights 2, forming the front and rear protective structure of the transfer box. The positioning plates 5 are located at the left and right ends of the base plate 1, fixedly connected to two adjacent uprights 2, and have end protective plates 4 rotatably mounted on their upper ends. The end protective plates 4 are detachably connected to the uprights 2, forming the front and rear protective structure of the transfer box. The combination of the uprights 2, side protective frames 3, positioning plates 5, and end protective plates 4 forms a continuous and adjustable protective system to protect the goods inside the transfer box and prevent them from falling during transport.
[0057] In the above description, the side protective frame 3 and the end protective plate 4 are linked by the positioning plate 5. The side protective frame 3 is responsible for lateral restraint, and the end protective plate 4 can be adjusted by rotation to adapt to the end protection requirements of goods of different heights. Together with the positioning plate 5, they form a closed protective structure, effectively restraining the displacement of goods during transportation. At the same time, the detachable design of the side protective frame 3 and the end protective plate 4 allows for quick adjustment of the protection range according to the size of the goods, improving loading and unloading efficiency.
[0058] Specifically, such as Figure 1 and Figure 2As shown, the side protective frame 3 includes an upper protective plate 31 and a lower protective plate 32. The lower protective plate 32 is rotatably connected to the base plate 1 via first pins 34 at both ends, providing bottom support and basic protection. The upper protective plate 31 is rotatably connected to the upper end of the lower protective plate 32 via hinges, forming a foldable segmented structure. Locking structures are symmetrically arranged on both sides of the upper end of both the upper and lower protective plates 31 and 32 for detachable connection to the uprights 2. This design allows the side protective frame 3 to be height-adjustable, and the opening and closing of the protective plates is achieved through a rotatable connection.
[0059] In the above description, the upper protective plate 31 can be folded upward or unfolded downward relative to the lower protective plate 32. The side protection height can be adjusted by adjusting the included angle between the two to adapt to the protection needs of goods of different sizes. When it is necessary to transfer large-volume goods, the upper protective plate 31 and the lower protective plate 32 can be fully unfolded to a horizontal state and the locking with the column 2 can be released to form a temporary opening, which makes it convenient for workers to load and unload goods directly from the side, effectively solving the problem of inconvenience in transferring large-volume goods caused by the fixed structure of traditional transfer boxes.
[0060] Specifically, such as Figure 1 and Figure 2 As shown, the first pin 34 is symmetrically arranged at both ends of the lower protective plate 32 and is used in conjunction with the pin hole provided on the column 2 to facilitate the installation of the lower protective plate 32.
[0061] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the end protective plate 4 is rotatably mounted between two columns 2 on the upper side of the positioning plate 5 via a second pin 41. Its lower end is hinged to the columns 2, enabling the end protective plate 4 to rotate. Simultaneously, the two columns 2 provide lateral fixation for the end protective plate 4, ensuring its stability during transport. A locking structure is symmetrically arranged on both sides of the upper end of the end protective plate 4, allowing for a detachable connection with the columns 2 to form a closed end protective surface.
[0062] In the above description, the end guard plate 4 can be rotated upwards or downwards via the second pin 41 to adjust the end guard height to accommodate goods of different sizes. When it is necessary to transfer large-volume goods, the connection between the upper locking structure and the column 2 can be released, and the end guard plate 4 can be rotated downwards to a horizontal state, which can form a temporary opening, making it convenient for workers to load and unload goods from the end, thus solving the problem of difficulty in transferring large-volume goods caused by traditional fixed end plates. This design takes into account both protective stability and operational flexibility.
[0063] Specifically, such as Figure 1 and Figure 2As shown, the upper protective plate 4 adopts a frame structure, consisting of an outer frame and an inner protective mesh. The outer frame is a rigid metal component, serving as the mounting base for the protective mesh. The inner protective mesh is fixed inside the outer frame by welding or snap-fitting to form a mesh protective surface. The protective mesh is woven from elastic metal wires, ensuring both structural strength and a certain degree of deformation capability.
[0064] As described above, during transport, the protective netting absorbs external impact energy through elastic deformation, providing cushioning protection for the goods. Simultaneously, the netting's mesh structure allows staff to directly observe the condition of the goods inside the container from the outside, facilitating real-time monitoring to ensure the goods are not shifted or damaged. This design balances protective performance with ease of operation, solving the problems of traditional solid baffles that neither provide adequate cushioning nor obstruct visibility.
[0065] In a preferred embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the locking structure includes a locking pin 36, a positioning sleeve 35, and an L-shaped locking member 37. The locking pin 36 is slidably mounted on the outer side of the upper end of the upper protective plate 31, the lower protective plate 32, and the end protective plate 4 via the positioning sleeve 35; the positioning sleeve 35 acts as a guide to ensure the sliding stability of the locking pin 36; the L-shaped locking member 37 is fixedly mounted on the outer surface of the column 2, with its vertical section facing upward to form a locking groove, which cooperates with the locking pin 36 to realize the locking function of the protective plate.
[0066] In the above description, the locking pin 36 is slid along the positioning sleeve 35 towards the column 2, so that its end is inserted into the vertical section groove of the L-shaped locking pin 37. The upper protective plate 31, the lower protective plate 32, and the end protective plate 4 are quickly fixed by the limiting action of the L-shaped locking pin 37. When it is necessary to adjust the protection height or transfer goods, simply slide the locking pin 36 in the opposite direction to disengage it from the L-shaped locking pin 37 to release the locking state. This structure is easy to operate and has a reliable connection, solving the problem of low efficiency of traditional bolt fixing methods.
[0067] In a preferred embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the cargo lifting mechanism includes a lifting plate 6 and a lifting adjustment assembly. The lifting plate 6 is horizontally and movably installed inside the groove 11 on the upper side of the base plate 1, serving as the direct bearing surface of the cargo. The lifting adjustment assembly is disposed between the base plate 1 and the lifting plate 6, and is hinged to the bottom of the lifting plate 6 to form an adjustable support structure.
[0068] As described above, the height of the lifting platform 6 can be precisely adjusted by operating the lifting adjustment component, allowing for vertical movement of goods within the transfer container. During loading and unloading, the lifting platform 6 is raised to a height close to the opening of the transfer container, reducing the bending or carrying effort required of workers. During transport, the lifting platform 6 is lowered to the surface of the base plate 1, enhancing cargo stability through the contact between the lifting platform 6 and the base plate 1. This height adjustment mechanism effectively improves cargo loading and unloading efficiency and reduces the intensity of manual labor.
[0069] Specifically, such as Figure 1 and Figure 4 As shown, the lifting adjustment assembly includes a hinge rod 61, a guide rod 63, and a transmission rod 64. Wherein:
[0070] One end of the hinge rod 61 is hinged to the bottom of the lifting plate 6, and the other end is hinged to the movable block 62, forming a rotatable support structure.
[0071] The guide rods 63 are symmetrically arranged in two grooves on the upper surface of the base plate 1, and their two ends are fixedly connected to the inner sidewall of the groove 12. The movable block 62 is slidably sleeved on the guide rods 63, and the guide rods 63 provide linear motion guidance for the movable block 62.
[0072] The transmission rod 64 is rotatably mounted in the middle of the slide groove on the upper surface of the base plate 1. The surface is provided with bidirectional threads, and both ends are threadedly connected to two first adjusting blocks 65 to form a screw transmission structure.
[0073] In the above description, the two first adjusting blocks 65 can be driven to move towards or away from each other along the slide groove by rotating the transmission rod 64. The first adjusting block 65 is connected to the adjacent movable block 62 through the connecting rod 67. When the first adjusting block 65 moves, the connecting rod 67 drives the movable block 62 to slide along the guide rod 63, thereby adjusting the height of the lifting plate 6 by rotating the hinge rod 61. This design allows the lifting plate 6 to be raised and lowered smoothly to meet the loading requirements of goods of different heights, while ensuring adjustment accuracy and load-bearing stability through mechanical transmission.
[0074] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, one end of the transmission rod 64 extends to the outside of the base plate 1, and an eccentric wheel 66 is fixedly installed at its end; the eccentric wheel 66 has a disc-shaped structure, and its central axis is offset from the axis of the transmission rod 64, forming an eccentric transmission feature; and an eccentric handle is fixedly connected to the outer edge of the eccentric wheel 66, which extends radially along the eccentric wheel 66 as a manual operation interface.
[0075] In the above description, by gripping the eccentric handle and applying force to rotate it, the eccentric wheel 66 can be driven to rotate around the axis of the transmission rod 64. Due to the eccentric design of the eccentric wheel 66, it will generate periodic radial displacement during rotation. This displacement is converted into rotational motion through the transmission rod 64, which in turn drives the transmission rod 64 to rotate within the central groove of the base plate 1. This design transforms the manual pushing and pulling action into the rotation of the transmission rod 64, simplifying the operation difficulty of adjusting the height of the lifting plate 6. At the same time, the eccentric structure amplifies the operating torque, making the adjustment process more effortless.
[0076] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, a connecting ring 9 is also provided on the outer middle part of the positioning plate 5, which is used to connect two adjacent transfer boxes in series by means of the connecting ring 9 and the connecting piece during use.
[0077] Example 2
[0078] Unlike Embodiment 1 described above, as Figure 1 , Figure 2 and Figure 5 As shown, the railway freight transfer box also includes several partition protection plates 7. The partition protection plates 7 are detachably installed between adjacent side protective frames 3 and connected to the side protective frames 3 to form a partition structure, which divides the internal space of the transfer box to avoid large displacement and collision of goods in the transfer box during transportation and prevent damage to the goods.
[0079] In a preferred embodiment, such as Figure 5 As shown, the partition protection plate 7 includes interconnected horizontal bars 71 and vertical bars 72. The horizontal bars 71 are horizontal main beams, and the vertical bars 72 are symmetrically and vertically connected between the two horizontal bars 71 to form a grid-like frame structure. A positioning rod 73 is movably installed at the connection node between the horizontal bars 71 and the vertical bars 72. The positioning rod 73 is slidably disposed in the guide groove 711 on the surface of the horizontal bar 71 along the length direction of the horizontal bar 71 and passes through the vertical bar 72 to form a longitudinal positioning structure. The end of the positioning rod 73 corresponds to the positioning hole 33 provided at the upper end of the outer frame of the upper protection plate 31 and the lower protection plate 32 to form a detachable connection.
[0080] In the above description, the second adjusting block 74 on the outside of the traction crossbar 71 (the second adjusting block 74 is fixedly connected to the positioning rod 73) can drive the positioning rod 73 to move horizontally along the guide groove 711; when the end of the positioning rod 73 is inserted into the positioning hole 33, the partition protection plate 7 and the side protection frame 3 are fixedly connected to form a stable internal partition structure; by adjusting the positioning rod 73 to be inserted into the positioning hole 33 at different positions, the installation position of the partition protection plate 7 can be flexibly adjusted to achieve precise division of the internal space of the transfer box, effectively limiting the displacement of goods and reducing the risk of collision.
[0081] Specifically, such as Figure 5 As shown, the partition protection plate 7 consists of a grid-like frame structure composed of horizontal bars 71 and vertical bars 72, with protective netting covering both sides. The protective netting is fixed to the frame formed by the horizontal bars 71 and vertical bars 72 by snap-fitting or welding, and is woven from elastic metal wire or high-strength fabric to form a flexible protective surface with buffering capacity. The mesh structure of the protective netting allows air circulation, while its elastic deformation characteristics can absorb the impact energy generated by the collision of goods.
[0082] In the above description, the protective netting, positioning rod 73, and positioning holes 33 together form a multi-layered protection system. After the positioning rod 73 is inserted into the positioning hole 33, it ensures a rigid connection between the partition protection plate 7 and the side protection frame 3; the protective netting serves as a second layer of protection, further limiting the horizontal displacement of the goods through physical blocking and deformation buffering. This design gives the partition protection plate 7 both structural stability and collision absorption capacity, effectively reducing the risk of damage to goods caused by shaking during transportation.
[0083] The usage process and operating principle of the railway freight transfer box described in this utility model include:
[0084] Usage process: First, when loading and unloading goods, the staff can disconnect the pin lock 36 at the upper end of the end guard plate 4 from the L-shaped clip 37 on the column 2, and rotate the end guard plate 4 downward to a horizontal state through the second pin 41 to form a temporary opening; at the same time, by rotating the eccentric wheel 66 through the eccentric handle, the transmission rod 64 is driven to rotate, so that the first adjusting block 65 moves towards the opposite side along the slide groove, and through the connecting rod 67, the movable block 62 slides along the guide rod 63, thereby adjusting the height of the lifting plate 6 to a position close to the opening of the transfer box, so as to facilitate the workers to move the goods.
[0085] After the goods are placed in, the lifting plate 6 is lowered to the surface of the base plate 1. The stability of the goods is enhanced by the fit between the lifting plate 6 and the base plate 1. Then, the end guard plate 4 is rotated upward to a vertical position, and the locking pin 36 is reinserted into the L-shaped clip 37 to complete the locking. If it is necessary to separate the internal space, the positioning rod 73 of the partition protection plate 7 can be pulled along the guide groove 711 of the crossbar 71 to the corresponding positioning hole 33 and inserted to fix the partition plate covered by the protective net to the side guard frame 3, forming an independent goods storage area.
[0086] Operating principle: This transfer box achieves cargo protection and operational optimization through the collaboration of multiple components: the external frame of the side protective frame 3 and the end protective plate 4 provides rigid support, the internal protective net absorbs external impact through elastic deformation, and allows observation of the cargo status; the lifting plate 6 achieves height adjustment through a screw-linkage mechanism composed of the hinge rod 61, guide rod 63 and transmission rod 64, and the eccentric wheel 66 converts manual rotation into rotational torque of the transmission rod 64, reducing the intensity of operation.
[0087] The protective netting of the partition plate 7 serves as a flexible buffer layer, forming a dual protection system together with the rigid connection between the positioning rod 73 and the positioning hole 33: the protective netting restricts cargo displacement and absorbs collision energy through deformation, while the positioning rod 73 ensures a stable connection between the partition plate and the side protective frame 3; in conjunction with the rotation design of the end protective plate 4 and the lifting function of the lifting plate 6, the transfer box achieves comprehensive optimization of improved loading and unloading efficiency, flexible cargo space division, and transportation safety while ensuring structural strength.
[0088] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
