Description

Technical Field

[0001] This utility model relates to the field of railway container stacking and positioning technology, and in particular to a railway container stacking and positioning device. Background Technology

[0002] In the field of rail transport, container stacking is an important task. With the continuous increase in rail transport volume, higher requirements are being placed on the stability, convenience, and assembly efficiency of container stacking.

[0003] A search revealed Chinese patent CN221458727U, which discloses a railway container stacking and positioning device, belonging to the field of railway container stacking and positioning technology. The key technical points of the device include a positioning mechanism and a support mechanism. The positioning mechanism is slidably connected to the inner wall of the support mechanism. The positioning mechanism includes a positioning plate, a slider, and a positioning hole. The fixing component can fix the slider. Although it can realize the stacking operation of containers to a certain extent, it still has many shortcomings.

[0004] Based on the above research and existing technology, it was found that most current railway container stacking technologies lack precise and effective positioning structures. During container stacking, it is difficult to ensure stable connection and fixation between upper and lower containers, often relying solely on simple stacking methods. This leads to dangerous situations during transportation, such as container displacement, shaking, or even falling due to train swaying and bumps, seriously affecting transportation safety and efficiency. Furthermore, the lack of convenient guiding and auxiliary structures during container stacking and assembly makes the operation complex and cumbersome, requiring significant time and manpower, and failing to meet the demands of fast and efficient railway transportation turnover. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes a railway container stacking and positioning device. The device comprises an I-shaped container body and fixing components. Upper and lower stacking limit plates are engaged in corresponding upper and lower grooves within the container body. The fixing components secure the limit plates at the four corners on both sides of the container body, achieving multi-point threaded fixing of the upper and lower limit plates through the container body, thus greatly enhancing the stability of the stacking between the upper and lower limit plates.

[0006] The technical solution to achieve the purpose of this utility model is: a railway container stacking and positioning device, including a container body, multiple sets of the container bodies stacked vertically, and further comprising;

[0007] A positioning mechanism is movably disposed between the upper and lower sets of container bodies;

[0008] The positioning mechanism includes an I-shaped limiting plate, in which the two stacked containers are engaged in the corresponding upper and lower grooves of the limiting plate;

[0009] The fixing components are provided at the four outer corners on both sides of the limiting plate and are used to fix the container body corresponding to the upper and lower grooves of the limiting plate.

[0010] In some embodiments, the upper and lower end groove openings of the limiting plate are provided with guide grooves that slope inward toward the center.

[0011] In some embodiments, at least two sets of positioning mechanisms are provided between the two sets of container bodies.

[0012] In some embodiments, the fixing component includes a threaded tube mounted on the outside of the limiting plate, with a fixing bolt threaded onto the threaded tube extending into the corresponding groove of the limiting plate, and the other end of the fixing bolt connected to a handwheel.

[0013] In some embodiments, the bottom surface of the upper and lower grooves of the limiting plate is provided with a protective groove, and an elastic rubber gasket is installed inside each protective groove.

[0014] In some embodiments, the upper and lower grooves of the limiting plate are provided with protective grooves, and two sets of protective grooves are provided with moving wheels inside the grooves at either the upper or lower end of the limiting plate. Elastic rubber pads are installed inside the remaining protective grooves.

[0015] Compared with existing technologies, the significant advantages of this invention are:

[0016] Firstly, this utility model, by setting up a positioning mechanism, includes an I-shaped limiting plate and fixing components. The container bodies stacked vertically are engaged in the corresponding upper and lower grooves of the limiting plate. The fixing components are used to fix the container bodies at the four corners on both sides of the limiting plate, realizing multi-point threaded fixing of the upper and lower sets of container bodies through the limiting plate. This effectively enhances the stability of the stacking of the container bodies vertically and vertically, and solves the problem that the existing containers are not stable due to the lack of reliable fixing methods, and are prone to shaking, displacement or even falling during transportation, which endangers transportation safety and efficiency.

[0017] Secondly, this utility model provides guide grooves that slope inward towards the center at the openings of the grooves at both the upper and lower ends of the limiting plate. When the upper container body is connected to the limiting plate, the inclined surface of the guide groove can guide the container body to smoothly embed into the upper groove of the limiting plate. This makes the operation simple, improves the convenience of container stacking, and solves the problem that in the existing container stacking process, it is difficult to connect the upper and lower containers, which is time-consuming and laborious, and it is difficult to quickly complete the stacking operation.

[0018] Thirdly, this utility model has a protective groove and a rubber gasket installed on the bottom surface of the upper and lower grooves of the limiting plate. When the end face of the container body contacts the bottom surface of the groove of the limiting plate, the rubber gasket protrudes outward and contacts the corresponding end face of the container body. After being squeezed, it retracts into the protective groove, which plays a temporary buffering role, reduces the collision damage between the container body and the limiting plate, and solves the problem that existing containers lack buffer protection when stacked, which easily causes wear and deformation of the container and related parts, and shortens the service life.

[0019] Fourthly, this utility model has movable wheels installed in the protective grooves inside the upper and lower grooves of the limiting plate. Before stacking the two container bodies, the positioning mechanism can be pre-adjusted with the help of the movable wheels, which facilitates the precise positioning and fixing of the upper and lower container bodies, improves the efficiency of container stacking, and solves the problems of inaccurate positioning and low fixing efficiency when stacking existing containers, which cannot meet the needs of efficient transportation and turnover.

[0020] Fifthly, the positioning mechanism of this utility model has a reasonable and relatively independent structure design, which can be quickly placed between the two limiting plates of the upper and lower stacks. The components are closely matched and the installation steps are simple and convenient to assemble, which greatly improves the assembly efficiency in the process of railway container stacking and solves the problem of inconvenient assembly of existing container stacking positioning devices.

[0029] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0030] This utility model provides an improved railway container stacking and positioning device. The technical solution of this utility model is as follows:

[0031] In Example 1, as Figure 1 - Figure 4 As shown, a railway container stacking and positioning device includes a container body 2, multiple sets of the container bodies 2 stacked vertically, and a positioning mechanism movably disposed between two sets of container bodies 2. The positioning mechanism includes an I-shaped limiting plate 1, with the two stacked container bodies 2 engaged in corresponding upper and lower grooves of the limiting plate 1; and a fixing component, which is provided at the four corners on both sides of the limiting plate 1 for fixing the container bodies 2 corresponding to the upper and lower grooves of the limiting plate 1. The I-shaped limiting plate 1 and the fixing component, with the stacked container bodies 2 engaged in corresponding upper and lower grooves of the limiting plate 1 and the fixing component used to fix the container bodies 2 at the four corners on both sides of the limiting plate 1, achieve multi-point threaded fixing of the two sets of container bodies 2 through the limiting plate 1, effectively enhancing the stability of the stacking of the container bodies 2.

[0032] like Figure 2 As shown, in one embodiment, the upper and lower end groove openings of the limiting plate 1 are provided with guide grooves 102 that slope inward towards the center. When the upper container body 2 docks with the limiting plate 1, the inclined surfaces of the guide grooves 102 at both ends of the limiting plate 1 guide the container body 2 to dock inside the upper groove of the limiting plate 1. The guide grooves 102 that slope inward towards the center are provided at the upper and lower end groove openings of the limiting plate 1. When the upper container body 2 docks with the limiting plate 1, the inclined surfaces of the guide grooves 102 can guide the container body 2 to smoothly embed into the upper groove of the limiting plate 1. The operation is simple, the convenience of container stacking is improved, and the problem of difficulty in docking upper and lower containers, time-consuming and labor-intensive, and difficulty in quickly completing the stacking operation is solved in the existing container stacking process.

[0033] To enhance the stacking effect between the upper and lower sets of container bodies 2, at least two sets of positioning mechanisms are provided between the two sets of limiting plates 1 in this technical solution.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, the fixing component includes a threaded tube 3 installed on the outside of the limiting plate 1. A fixing bolt 301, extending into the corresponding groove of the limiting plate 1, is threadedly connected to the threaded tube 3. The other end of the fixing bolt 301 is connected to a handwheel turntable 302. By providing four sets of fixing components on both sides of the limiting plate 1, when the upper and lower container bodies 2 are aligned within the corresponding upper and lower grooves of the limiting plate 1, multi-point threaded fixing of the upper and lower container bodies 2 is achieved through the limiting plate 1, enhancing the stability of the stacking of the container bodies 2. The design of rotating the handwheel turntable 302 allows for convenient and quick movement of the fixing bolt 301 into the threaded tube 3, thereby achieving threaded fixing of the limiting plate 1 and the container body 2. The handwheel turntable 302 provides a larger force application surface for the operator, making operation more labor-saving and convenient compared to directly rotating the small fixing bolt 301. Operators can easily rotate the handwheel turntable 302 to make the fixing bolt 301 move smoothly and quickly in the threaded tube 3 by means of the thread transmission principle, accurately abutting the container body 2, forming a reliable fixation at the four corners on both sides of the limit plate 1, effectively enhancing the stability of stacking between the upper and lower container bodies 2, greatly improving the efficiency of the fixing operation, and making the entire railway container stacking and positioning process more efficient and smooth.

[0035] Example 2, based on Example 1, such as Figure 2 As shown, the bottom surface of the upper and lower grooves of the limiting plate 1 is provided with protective grooves 101, and each protective groove 101 is equipped with an elastic rubber gasket 4.

[0036] By providing a protective groove 101 and a rubber pad 4 inside the protective groove 101 on the bottom surface of the upper and lower grooves of the limiting plate 1, when the end face of the upper and lower corresponding container body 2 contacts the bottom surface of the upper and lower grooves of the limiting plate 1, the rubber pad 4 inside the protective groove 101 will protrude outward and contact the corresponding end face of the container body 2. The rubber pad 4 will shrink into the protective groove 101 under elastic compression, thus achieving a temporary buffering effect when the container body 2 docks with the end face of the upper and lower grooves of the limiting plate 1.

[0037] In Example 3, based on Example 1, as follows: Figure 5 As shown, the upper and lower grooves of the limiting plate 1 are both provided with protective grooves 101. Two sets of protective grooves 101 are provided inside the grooves at either the upper or lower end of the limiting plate 1, and movable wheels 5 are installed inside them. Elastic rubber pads 4 are installed inside the remaining protective grooves 101.

[0038] By setting a protective groove 101 inside the upper and lower grooves of the limiting plate 1, and setting a rubber pad 4 and a moving wheel 5 inside the protective groove 101 respectively, the positioning mechanism can adjust the corresponding position before stacking the two container bodies 2, so as to facilitate the upper container body 2 and the lower container body 2 to be positioned and fixed vertically.

[0039] The specific working method is as follows: First, when preparing to carry out container stacking operations, place the limiting plate 1 in the positioning mechanism between the upper and lower sets of container bodies 2 to be stacked, and ensure that the upper and lower grooves of the limiting plate 1 are aligned with the upper and lower container bodies 2 respectively.

[0040] Since the upper and lower end grooves of the limiting plate 1 are provided with guide grooves 102, when the upper container body 2 moves downward to prepare to dock with the limiting plate 1, the inclined surface of the guide groove 102 will play a guiding role, guiding the container body 2 to accurately embed into the upper groove of the limiting plate 1, thus initially achieving positioning.

[0041] Next, the final fixing is achieved by operating the fixing assembly. The fixing assembly includes a threaded tube 3 installed on the outside of the limiting plate 1. A fixing bolt 301 extending into the corresponding groove of the limiting plate 1 is threadedly connected to the threaded tube 3. The other end of the fixing bolt 301 is connected to a handwheel 302. The operator rotates the handwheel 302, using the threaded transmission principle to make the fixing bolt 301 move smoothly in the threaded tube 3, gradually going deeper into the groove, until the fixing bolt 301 is tightly against the side of the container body 2. After this operation is completed at the four corners on both sides of the limiting plate 1, the upper and lower sets of container bodies 2 are fixed at multiple points by the limiting plate 1, ensuring the stability and reliability of the stacking structure.

[0042] Throughout the process, if the end face of the container body 2 contacts the bottom surface of the groove of the limiting plate 1, the rubber pad 4 inside the protective groove 101 opened inside the upper and lower grooves of the limiting plate 1 will play a buffering role to avoid damage caused by hard collision. Moreover, if the position of the limiting plate 1 needs to be adjusted in advance before stacking, the moving wheels 5 set in the protective groove 101 inside the upper and lower grooves of the limiting plate 1 can be used to help to quickly and accurately complete the stacking and positioning operation of railway containers.

[0043] The positioning mechanism of this utility model has a reasonable and relatively independent structure design, which can be quickly placed between the two container bodies 2 stacked on top of each other. The components are closely matched and the installation steps are simple and easy to assemble, which greatly improves the assembly efficiency in the process of railway container stacking and solves the problem of inconvenient assembly of existing container stacking positioning devices.

[0044] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
