Description

Technical Field

[0001] This application belongs to the field of railway freight car technology, and particularly relates to a transport car and a transport train. Background Technology

[0002] Transport cars are primarily used to carry automobiles. With the continuous growth of railway freight demand, transport cars often adopt a double-layer structure, securing the cars to the upper and lower platforms of the transport car, thereby improving transportation efficiency.

[0003] However, there are significant problems with the relevant technologies: First, it is not easy to transport cars to or from the upper platform during loading and unloading, resulting in cumbersome and inefficient loading and unloading operations; Second, the upper platform is often fixed when not in use, and the spatial layout cannot be flexibly adjusted, resulting in low utilization of the vehicle's internal space. For example, some larger or specific models of cars cannot be stored using the lower storage space, leaving the lower storage space empty and limiting the improvement of transportation capacity.

[0004] Therefore, there is an urgent need for an improved transport vehicle design to solve the problems of difficult loading and unloading and low space utilization. Utility Model Content

[0005] This application aims to at least address the problems of loading and unloading difficulties and low space utilization in the existing technology.

[0006] In a first aspect, this application provides a transport vehicle, including: a body and a lifting device; The compartment is equipped with a transport port; The lifting device includes a lifting assembly and a lifting platform. The lifting platform is movably disposed inside the compartment. The lifting assembly is connected to the lifting platform for driving the lifting platform to move in the height direction of the compartment, and has a first posture, a second posture and a third posture. When the lifting platform is in the first posture, the lifting platform is tilted, and the end of the lifting platform facing the transport port is lower than the end of the lifting platform away from the transport port. When the lifting platform is in the second posture, the lifting platform is arranged in parallel and abuts against the bottom surface of the box body; When the lifting platform is in the third posture, the lifting platform is arranged in parallel, and the lifting platform and the bottom surface of the compartment form a lower accommodating space.

[0007] According to one embodiment of this application, the lifting assembly includes lifting sections disposed at both ends of the lifting platform, and the lifting end of each lifting section is connected to the lifting platform.

[0008] According to one embodiment of this application, the number of lifting parts is four, and the lifting ends of the four lifting parts are connected one-to-one to the corners of the lifting platform.

[0009] According to one embodiment of this application, each of the lifting units includes a power source, a set of rotating wheels, and a lifting belt; The rotating wheel is rotatably mounted on the inner wall of the compartment; The output end of the power source is connected to the tension belt drive; The lifting belt is located around the rotating wheel, and the end of the lifting belt is connected to the lifting platform.

[0010] According to one embodiment of this application, the rotating wheel assembly includes a first rotating wheel, a second rotating wheel, and a third rotating wheel; The first rotating wheel, the second rotating wheel, and the third rotating wheel are all rotatably mounted on the inner wall of the compartment; in the height direction of the compartment, the position of the second rotating wheel is lower than the positions of the first rotating wheel and the third rotating wheel; The lifting belts are sequentially arranged around the first rotating wheel, the second rotating wheel, and the third rotating wheel.

[0011] According to one embodiment of this application, the side wall of the compartment is provided with a first locking pin hole, and the side wall of the lifting platform is provided with a second locking pin hole corresponding to the first locking pin hole. When the first locking pin hole and the second locking pin hole correspond, the first locking pin hole and the second locking pin hole are used to insert a locking pin.

[0012] According to one embodiment of this application, there are multiple first locking pin holes, which are spaced apart and arranged along the height direction of the compartment.

[0013] According to one embodiment of this application, the body includes two end walls, two side walls, and a recessed bottom frame; The two end walls and two side walls are enclosed on the recessed base frame, and the transport opening is provided in the end wall; the lifting platform is movably mounted on the side wall; The surface of the concave base frame facing the lifting platform includes a first plane, a concave surface, and a second plane connected in sequence, with the concave surface recessed in a direction away from the lifting platform.

[0014] According to one embodiment of this application, the transport port includes an inlet and an outlet, the inlet and the outlet being correspondingly located on the end wall. Wherein, when the lifting platform is in the first posture, the end of the lifting platform facing the vehicle entrance is lower than the end of the lifting platform facing the vehicle exit; or, the end of the lifting platform facing the vehicle entrance is higher than the end of the lifting platform facing the vehicle exit.

[0015] Secondly, this application provides a transport train, including: transport carriages.

[0016] In summary, this application includes at least one of the following beneficial technical effects: In its first position, the lifting platform is tilted with the end facing the transport opening lower than the end facing away from it, creating a ramp structure that facilitates car entry and exit, significantly reducing the difficulty of loading and unloading vehicles. When the lifting platform switches to its second position, it is parallel to the ground and rests against the bottom of the cargo box, providing a stable parking surface for cars and ensuring safety during transport. When the lifting platform is adjusted to its third position, it is parallel to the ground and forms a lower storage space with the bottom of the cargo box, while the area above the lifting platform forms an upper storage space. This design effectively improves the space utilization inside the cargo box, making it particularly suitable for the storage needs of larger vehicles of certain models, and avoiding the problem of empty lower space.

[0017] The lifting assembly precisely controls the posture switching of the lifting platform through a transmission connection, allowing the entire transport vehicle to flexibly adjust its layout according to actual needs.

Detailed Implementation

[0021] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0022] Transport cars play a crucial role in the railway freight system, primarily used to efficiently carry vehicles such as cars. With the increasing demand for railway freight, the industry has widely adopted a double-deck design, securing cars to both the upper and lower platforms of the transport car to improve overall transport efficiency.

[0023] However, existing technical solutions have significant shortcomings. During the loading and unloading process, it is difficult to smoothly transport cars to or safely transfer them from the upper platform, resulting in a complex and lengthy operation that not only consumes a lot of manpower and time but also easily causes vehicle scratches or damage, significantly reducing loading and unloading efficiency.

[0024] Meanwhile, the upper platform is typically in a fixed position when not in use, lacking dynamic adjustment capabilities, resulting in a rigid internal space layout. For example, when transporting specific models of larger vehicles, the lower storage space is often left idle because the upper platform cannot be flexibly adjusted to fit the actual vehicle dimensions, severely hindering the optimization of transport capacity. Furthermore, the inefficient use of space means that some vehicles cannot be loaded due to size mismatch, further limiting the adaptability and economy of the transport system. These problems collectively contribute to the difficulty in improving transport efficiency.

[0025] The following is for reference. Figures 1-5 This application describes a transport car and a transport train according to embodiments thereof.

[0026] like Figures 1-4 As shown, the transport vehicle includes: a body 100 and a lifting device; The compartment 100 is equipped with a transport port; The lifting device includes a lifting assembly 210 and a lifting platform 310. The lifting platform 310 is movably disposed inside the compartment 100. The lifting assembly 210 is connected to the lifting platform 310 for driving the lifting platform 310 to move in the height direction of the compartment 100, and has a first posture, a second posture and a third posture. like Figure 2 and Figure 3 As shown, when the lifting platform 310 is in the first posture, the lifting platform 310 is tilted, and the end of the lifting platform 310 facing the transport opening is lower than the end of the lifting platform 310 away from the transport opening; when the lifting platform 310 is in the second posture (not shown), the lifting platform 310 is parallel, and the lifting platform 310 abuts against the bottom surface of the container 100; Figure 1 As shown, when the lifting platform 310 is in the third posture, the lifting platform 310 is arranged in parallel, and the lifting platform 310 and the bottom surface of the box 100 form a lower receiving space.

[0027] The working principle of this embodiment is as follows: The transport compartment achieves efficient loading and unloading of cars and flexible use of space through the cooperation of the compartment 100 and the lifting device. The compartment 100 is provided with a transport opening, serving as a passage for cars to enter and exit the compartment, providing convenient conditions for loading and unloading operations. The lifting device consists of a lifting assembly 210 and a lifting platform 310, wherein the lifting platform 310 is movably installed inside the compartment 100, and the lifting assembly 210 is driven to move the lifting platform 310 along the height direction of the compartment 100, and can switch to a first posture, a second posture, and a third posture.

[0028] When the lifting platform 310 is in the first position, it is tilted and the end facing the transport opening is lower than the end facing away from the transport opening, thus forming a ramp structure that facilitates the entry or exit of cars, significantly reducing the difficulty of loading and unloading vehicles.

[0029] Furthermore, when the lifting platform 310 switches to the second posture, it is set parallel to and abuts against the bottom surface of the box 100, thereby providing a stable parking plane for the car and ensuring safety during transportation.

[0030] Furthermore, when the lifting platform 310 is adjusted to the third posture, it is set parallel to the bottom of the compartment 100 to form a lower storage space, and the area above the lifting platform 310 forms an upper storage space. This design effectively improves the space utilization rate inside the compartment, and is especially suitable for the storage needs of certain models of vehicles with larger dimensions, avoiding the problem of empty lower space.

[0031] Specifically, the lifting assembly 210 precisely controls the posture switching of the lifting platform 310 through a transmission connection, enabling the entire transport compartment to flexibly adjust its layout according to actual needs. This simplifies the loading and unloading process and optimizes space utilization efficiency, thereby solving the problems of difficult loading and unloading of cars and low utilization of interior space.

[0032] In some embodiments, the lifting assembly 210 includes lifting sections disposed at both ends of the lifting platform 310, and the lifting end of each lifting section is connected to the lifting platform 310.

[0033] In actual implementation, there are four lifting units, and the lifting ends of the four lifting units are connected to the corners of the lifting platform 310 one by one.

[0034] like Figure 4 As shown, in some embodiments, each of the lifting units includes a power source 211, a rotating wheel assembly 212, and a lifting belt 213; The rotating wheel is rotatably mounted on the inner wall of the compartment 100; The output end of the power source 211 is connected to the lifting belt 213 for transmission. The lifting belt 213 is located on the periphery of the rotating wheel, and the end of the lifting belt 213 is connected to the lifting platform 310.

[0035] In this embodiment, a highly efficient and stable lifting drive system is constructed using a power source 211, a rotating wheel assembly 212, and a lifting belt 213. The output end of the power source 211 forms a direct transmission relationship with the lifting belt 213, avoiding energy loss in intermediate conversion stages and significantly improving power transmission efficiency. The rotating wheel assembly 212 is installed on the inner wall surface according to the internal spatial layout characteristics of the compartment 100, ensuring the smoothness and stability of the lifting process. The end of the lifting belt 213 is connected to the lifting platform 310, and the linear traction of the lifting belt 213 achieves precise vertical displacement of the lifting platform 310, adapting to the switching requirements of different postures. This improves the convenience of loading and unloading operations and the flexible adjustment capability of the interior space of the compartment.

[0036] In actual implementation, the rotating wheel assembly 212 includes a first rotating wheel 2121, a second rotating wheel 2122, and a third rotating wheel 2123; The first rotating wheel 2121, the second rotating wheel 2122, and the third rotating wheel 2123 are all rotatably mounted on the inner wall of the compartment 100; in the height direction of the compartment 100, the position of the second rotating wheel 2122 is lower than the positions of the first rotating wheel 2121 and the third rotating wheel 2123; the lifting belt 213 is sequentially arranged around the first rotating wheel 2121, the second rotating wheel 2122, and the third rotating wheel 2123.

[0037] In some embodiments, the side wall of the compartment 100 is provided with a first locking pin hole, and the side wall of the lifting platform 310 is provided with a second locking pin hole corresponding to the first locking pin hole. When the first locking pin hole and the second locking pin hole correspond, the first locking pin hole and the second locking pin hole are used to insert a locking pin.

[0038] In this embodiment, the first locking pin hole refers to a through-hole structure provided on the side wall of the housing 100. It can be circular, square, or other hole shapes adapted to the locking pin shape, and its purpose is to provide a reliable fixing point for the lifting platform 310. The second locking pin hole refers to a through-hole structure provided on the side wall of the lifting platform 310 corresponding to the first locking pin hole, ensuring that it aligns with the first locking pin hole only when the lifting platform 310 reaches a predetermined position. A locking pin is a locking component that inserts into the first and second locking pin holes. It can be made of metal and is inserted manually or automatically to fix the position of the lifting platform 310.

[0039] In actual implementation, there are multiple first locking pin holes, which are spaced apart and arranged along the height direction of the body 100.

[0040] like Figure 5 As shown, in some embodiments, the compartment 100 includes two end walls 110, two side walls 120, and a recessed bottom frame 130; The two end walls 110 and the two side walls 120 are arranged around the recessed base frame 130, and the end walls 110 have the transport opening; the lifting platform 310 is movably arranged on the side walls 120. The surface of the concave base 130 facing the lifting platform 310 includes a first plane, a concave surface, and a second plane connected in sequence, with the concave surface recessed in a direction away from the lifting platform 310.

[0041] In this embodiment, the first and second planes provide standard storage areas for conventional vehicles. Compared to the first and second planes, the concave surface increases the lower distance, significantly improving its adaptability to larger vehicles. This design achieves overall optimization of space utilization efficiency without increasing the external dimensions of the cargo box.

[0042] In some embodiments, the transport port includes an inlet and an outlet, the inlet and the outlet being correspondingly located on the end wall 110. like Figure 2 As shown, when the lifting platform 310 is in the first posture, the end of the lifting platform 310 facing the vehicle entrance is lower than the end of the lifting platform 310 facing the vehicle exit; or, as Figure 3As shown, the end of the lifting platform 310 facing the vehicle entrance is higher than the end of the lifting platform 310 facing the vehicle exit.

[0043] Specifically, the transport port refers to the opening structure used for vehicles to enter and exit the compartment 100. It can be further divided into an inlet and an outlet to realize separate loading and unloading functions, with the aim of improving loading and unloading efficiency and reducing operational conflicts.

[0044] In practical applications, the vehicle entry and exit points can be located on opposite sides of the end wall 110 to ensure symmetrical layout and facilitate matching with the movement trajectory of the lifting platform 310. Furthermore, the first posture of the lifting platform 310 refers to the state in which its tilt direction is dynamically adjusted according to loading and unloading requirements. This can be achieved by controlling the lifting assembly 210 to flexibly adjust the height at both ends of the lifting platform 310, thereby optimizing the smoothness of the loading and unloading process.

[0045] In this embodiment, by dividing the transport port into an inlet and an outlet, and combining this with the attitude adjustment of the lifting platform 310, the vehicle loading and unloading paths are separated. For example, when a vehicle needs to enter the cargo box 100, the end of the lifting platform 310 facing the inlet is lower than the end facing the outlet, and this tilted design facilitates the vehicle's entry into the cargo box 100; conversely, when a vehicle needs to leave the cargo box 100, the end of the lifting platform 310 facing the inlet is higher than the end facing the outlet, facilitating the vehicle's departure. Based on this, the symmetrical layout of the inlet and outlet, combined with the dynamic adjustment of the lifting platform 310, significantly improves loading and unloading efficiency.
