The roller abuts against the top surface of the guide rail.

[0010] Furthermore, the moving mechanism also includes a first positioning element and a second positioning element, both of which are disposed within the accommodating space. The first positioning element and the second positioning element are sleeved on the connecting pin and located on both sides of the roller.

[0011] Furthermore, the lifting mechanism includes a base, a lifting arm, and a support arm. Both the lifting arm and the support arm are hinged to the base. The lifting arm is foldable, and the support arm is telescopic.

[0012] Furthermore, the hoisting mechanism also includes a first driving member, the first end of which is hinged to the base at a first hinge point, and the second end of which is hinged to the support arm at a second hinge point. The support arm has an initial position and a supported position, and the first driving member can drive the support arm to switch between the initial position and the supported position.

[0013] Furthermore, the lifting mechanism also includes a second drive member and a third drive member. The lifting arm includes a first arm body and a second arm body.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0032] like Figures 1 to 3 As shown, in this embodiment, the railway vehicle includes: a railway car body 10, a hoisting mechanism 20, and a moving mechanism 30. The railway car body 10 is provided with a guide groove 11 extending along its length. The hoisting mechanism 20 is disposed on the railway car body 10. The moving mechanism 30 is disposed at the bottom of the hoisting mechanism 20 and is movably disposed within the guide groove 11, so that the hoisting mechanism 20 is movably disposed along the length of the railway car body 10.

[0033] Applying the technical solution of this embodiment, a guide groove 11 extending along its length is provided on the railway car body 10. A lifting mechanism 20 is mounted on the railway car body 10, and a moving mechanism 30 is mounted at the bottom of the lifting mechanism 20. The moving mechanism 30 is movably mounted within the guide groove 11, allowing the lifting mechanism 20 to move along the length of the railway car body 10. Through this arrangement, when lifting and transporting containers 1 of different sizes, the moving mechanism can drive the lifting mechanism 20 to move, thereby achieving adaptation to containers 1 of different sizes. This enables the railway vehicle to lift containers 1 of different sizes. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies where railway container flatcars cannot load and unload containers of various sizes.

[0034] The above setup not only improves loading and unloading efficiency and flexibility, but also enables the rapid positioning and loading / unloading of containers of different sizes and locations.

[0035] like Figure 1 , Figure 2 as well as Figure 4 As shown, in this embodiment, the railway vehicle also includes a guide rail component 40, which is disposed within the guide groove 11. The moving mechanism 30 is guided and cooperates with the guide rail component 40. The cooperation between the guide rail component 40 and the moving mechanism 30 further improves the stability and accuracy of the moving mechanism 30's movement within the guide groove 11. This enables the moving mechanism 30 to move more smoothly and accurately, and ensures the stability of the hoisting mechanism 20 during loading and unloading.

[0036] like Figure 1 , Figure 2 as well as Figure 4As shown, in this embodiment, the moving mechanism 30 includes a moving base 31, which has a receiving space 311. The moving base 31 has an opening 312 communicating with the receiving space 311 on the side facing the guide rail member 40. A portion of the guide rail member 40 is located at the opening 312, and another portion is located within the receiving space 311. Through the cooperation between the opening 312 and the guide rail member 40, the moving base 31 can slide along the guide rail member 40. Simultaneously, the design of the opening 312 avoids a plug-in connection between the moving base 31 and the guide rail member 40, thereby making the position of the moving base 31 more stable during movement, thus improving the durability and stability of the moving mechanism 30.

[0037] like Figure 1 , Figure 2 as well as Figure 4 As shown, in this embodiment, an inner stop protrusion 3121 is provided at the opening 312, and an outer stop protrusion 41 is provided on the top of the guide rail 40. The inner stop protrusion 3121 and the outer stop protrusion 41 engage in a stop-and-go action. The engagement of the inner stop protrusion 3121 and the outer stop protrusion 41 restricts the position of the movable seat 31, preventing it from detaching from the guide rail 40, thereby ensuring the safety and stability of the lifting mechanism 20 during loading and unloading. Furthermore, this design improves the control precision of the moving mechanism 30 and reduces the risk of operational errors.

[0038] like Figure 1 , Figure 2 as well as Figure 4 As shown, in this embodiment, the moving mechanism 30 further includes a connecting pin 32 and a roller 33. The connecting pin 32 is inserted into the receiving space 311 and connected to the moving seat 31. The roller 33 is rotatably mounted on the connecting pin 32 and located within the receiving space 311. The axial direction of the connecting pin 32 is perpendicular to the extension direction of the guide rail 40, and the roller 33 abuts against the top surface of the guide rail 40. The contact between the roller 33 and the top surface of the guide rail 40 reduces the frictional resistance when the moving seat 31 slides along the guide rail 40, improving the smoothness and efficiency of the sliding. This makes the movement of the moving mechanism 30 more effortless and the operation more convenient.

[0039] like Figure 1 , Figure 2 as well as Figure 4As shown, in this embodiment, the moving mechanism 30 further includes a first positioning member 34 and a second positioning member 35. Both the first positioning member 34 and the second positioning member 35 are disposed within the accommodating space 311, and are sleeved on the connecting pin 32 and located on both sides of the roller 33. By fixing the connecting pin 32 with the first positioning member 34 and the second positioning member 35, the stable position of the roller 33 on the guide rail 40 is ensured, preventing lateral displacement of the roller 33 during sliding. This effectively improves the sliding stability and reliability of the moving mechanism 30, reduces the lateral sway of the roller 33, and ensures the smooth operation of the lifting mechanism 20 during loading and unloading.

[0040] like Figure 2 as well as Figures 5 to 10 As shown, in this embodiment, the lifting mechanism 20 includes a base 21, a lifting arm 22, and a support arm 23. Both the lifting arm 22 and the support arm 23 are hinged to the base 21. The lifting arm 22 is foldable, and the support arm 23 is telescopic. By folding the lifting arm 22 and telescopically extending the support arm 23, the lifting mechanism 20 achieves flexible operation during container loading and unloading and compact storage during transportation, improving the equipment's versatility and space utilization. This allows the lifting mechanism 20 to be retracted when not in use, reducing space occupation and increasing the loading capacity of railway vehicles. When in use, the extended lifting arm 22 and support arm 23 provide sufficient lifting force and operating range to meet the loading and unloading needs of containers 1 of different sizes and weights.

[0041] like Figure 2 as well as Figures 5 to 10 As shown, in this embodiment, the hoisting mechanism 20 further includes a first driving member 24. The first end of the first driving member 24 is hinged to the base 21 at a first hinge point 51, and the second end of the first driving member 24 is hinged to the support arm 23 at a second hinge point 52. The support arm 23 has an initial position and a supported position, and the first driving member 24 can drive the support arm 23 to switch between the initial position and the supported position. Through the driving of the first driving member 24, the rapid switching of the support arm 23 between the initial position and the supported position is achieved, improving the response speed and operational flexibility of the hoisting mechanism 20.

[0042] Specifically, the support arm 23 can be quickly deployed when loading and unloading container 1, providing stable support and ensuring the smoothness and safety of the hoisting process; during transportation, the support arm 23 can be quickly retracted to its initial position, reducing the space occupied and improving the loading capacity and transportation efficiency of railway vehicles.

[0043] like Figure 2 as well as Figures 5 to 10As shown, in this embodiment, the support arm 23 includes a support cylinder 231 and a telescopic rod 232 disposed within the support cylinder 231. The telescopic rod 232 can extend out of the support cylinder 231 or retract into the support cylinder 231. By extending and retracting the telescopic rod 232 within the support cylinder 231, the length of the support arm 23 can be adjusted to adapt to the loading and unloading needs of containers 1 of different sizes and weights.

[0044] Specifically, the support arm 23 can provide appropriate support force and operating range when loading and unloading containers of different sizes, ensuring the smoothness and safety of the lifting process.

[0045] like Figure 2 as well as Figures 5 to 10 As shown, in this embodiment, the hoisting mechanism 20 further includes a second drive member 25 and a third drive member 26. The hoisting arm 22 includes a first arm body 221 and a second arm body 222. The first end of the first arm body 221 is hinged to the base 21 at a third hinge point 53, and the second end of the first arm body 221 is hinged to the end of the second arm body 222 at a fourth hinge point 54. The first end of the second drive member 25 is hinged to the base 21 at a fifth hinge point 55, and the second end of the second drive member 25 is hinged to the first arm body 221 at a sixth hinge point 56. The first end of the third drive member 26 is hinged to the first arm body 221 at a seventh hinge point 57, and the second end of the third drive member 26 is hinged to the second arm body 222 at an eighth hinge point 58. Through the driving of the second drive member 25 and the third drive member 26, the folding and unfolding of the hoisting arm 22, as well as the angle adjustment between the first arm body 221 and the second arm body 222, are realized, improving the operating range and flexibility of the hoisting mechanism 20.

[0046] Specifically, the lifting arm 22 can provide sufficient lifting force and operating range when loading and unloading containers to meet the loading and unloading needs of containers 1 of different sizes and weights; during transportation, the lifting arm 22 can be quickly folded, reducing the space occupied and improving the loading capacity and transportation efficiency of railway vehicles.

[0047] like Figures 1 to 3 as well as Figures 5 to 10 As shown, in this embodiment, there are two guide slots 11, two lifting mechanisms 20, and two moving mechanisms 30. The guide slots 11 are respectively set at both ends of the railway car body 10, and the two moving mechanisms 30 are set one-to-one with the two lifting mechanisms 20. The two moving mechanisms 30 are respectively set in the two guide slots 11. By setting guide slots 11 at both ends of the railway car body 10, and the corresponding lifting mechanisms 20 and moving mechanisms 30, simultaneous loading and unloading of both sides of the container 1 is realized, improving loading and unloading efficiency and flexibility.

[0048] Specifically, the lifting mechanism 20 can operate simultaneously from both sides, reducing loading and unloading time and improving loading and unloading efficiency; at the same time, the symmetrical arrangement on both sides ensures the balance of the vehicle during the loading and unloading process and improves the safety of operation.

[0049] It should be noted that, Figure 5 The initial state when the container was unloaded is shown. Figure 6 The diagram shows the state in which the first drive member drives the support arm 23 to be supported. Figure 7 The diagram shows the state where the telescopic rod 232 extends out of the support cylinder 231. At this time, the end of the telescopic rod 232 away from the support cylinder 231 is in contact with the ground, which makes the position of the railway car body 10 more stable. Figure 8 The third drive unit 26 shown drives the second arm 222 to swing, thereby causing the end of the second arm 222 away from the first arm 221 to be higher than the top of the container 1. Figure 9 The diagram shows that the second drive unit 25 drives the first arm 221 to swing, thereby causing the second arm 222 to lift the container 1. Figure 10 The diagram shows the third drive unit 26 driving the second arm 222 to retract, thereby causing the container 1 to fall to the ground.

[0050] The railway vehicle in this embodiment not only solves the problem of loading and unloading container 1 under the condition of no dedicated loading and unloading machinery, but also achieves high efficiency, high flexibility and high safety of railway vehicle through the mobility, telescopic and foldable nature of the hoisting mechanism 20 and the guiding and positioning design of the moving mechanism 30.

[0051] Furthermore, the railway vehicles have a simple overall design and are easy to operate, which can effectively reduce operating costs and improve the convenience and efficiency of rail-road intermodal transport.

[0052] In the description of this utility model, it should be understood that "multiple" means a quantity of two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0053] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0054] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
