Description

Technical Field

[0001] This utility model relates to the field of containers, and in particular to a container chassis and a container. Background Technology

[0002] Steel coil containers are special containers designed for transporting coiled goods such as steel coils. To prevent the steel coils from rolling and shifting during transport, traditional steel coil containers typically have pads at the bottom to form a V-shaped storage area to secure the coils. To accommodate different cargo loading requirements, the bottom often features a hinged flap structure, allowing the pads to be hidden or revealed as needed.

[0003] However, existing flip-top structures have several problems: First, movable flip-tops typically use an all-metal structure, which is heavy and difficult for workers to operate, often requiring two people to operate simultaneously to complete the opening and closing action; second, because the pad needs to be accommodated in the receiving groove of the bottom crossbeam, the movable flip-top cannot be flipped directly. The entire movable flip-top must first be pulled vertically upwards to remove the pad from the receiving groove before the flipping operation can be performed. This requires the hinge structure to simultaneously meet both vertical lifting and rotational flipping motion modes, resulting in a complex hinge structure that is prone to jamming during opening and closing, making operation extremely inconvenient; third, the all-metal structure combined with the complex hinge mechanism not only results in high manufacturing costs but also increases the difficulty and cost of maintenance. Therefore, it is necessary to provide a container chassis structure that is simple in structure, easy to operate, and economical in cost. Utility Model Content

[0020] The present invention will now be described in more detail with reference to the accompanying drawings, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being broadly known to those skilled in the art and is not intended to limit the present invention.

[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0022] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer as will be explained below. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0023] Example 1 This embodiment provides a container chassis; please refer to [reference needed]. Figures 1-4 ,include: Multiple spaced bottom beam groups 1, each bottom beam group 1 includes two bottom beams 11, and the adjacent bottom beams 11 in the two bottom beam groups 1 are connected by a fixed floor 2, which is placed on the bottom beams 11. The raised floor 3 is placed on the bottom crossbeam 11 between the two fixed floors 2; the raised floor 3 includes two surfaces arranged opposite each other, one surface is provided with pads 4, and the other surface is provided with lifting members 5; The two bottom crossbeams 11 form an accommodating space for accommodating the pad 4.

[0024] Specifically, please refer to Figures 3-4 The base frame includes multiple spaced-apart bottom beam groups 1, each consisting of two parallel bottom beams 11, forming an accommodating space between them. Adjacent bottom beam groups 1 are connected by fixed floorboards 2, which are mounted on the bottom beams 11 to form a stable connection structure. Between two fixed floorboards 2, a reversible movable floorboard 3 is provided, also positioned on the bottom beams 11 and on the same plane as the fixed floorboards 2.

[0025] In one possible embodiment, please refer to Figure 5 In each bottom beam assembly 1, two bottom beams 11 are arranged opposite each other, and their bottoms are connected to form an upward-facing opening, within which a receiving space is formed to accommodate the pad 4. In another possible embodiment, please refer to... Figure 6 In each bottom beam group 1, the two bottom beams 11 are arranged opposite each other, and an accommodating space is formed between the two bottom beams 11.

[0026] The raised floor 3 has two opposing surfaces, one surface equipped with pads 4 and the other surface equipped with lifting elements 5. When pads 4 are needed to secure the steel coil 6, the surface with pads 4 is placed upwards, with pads 4 positioned above the raised floor 3. When pads 4 are not needed, workers use the lifting elements 5 to rotate the raised floor 3 180 degrees, so that the surface with the lifting elements 5 is facing upwards. At this point, pads 4 are hidden downwards within the space between the two bottom crossbeams 11, leaving the raised floor 3 flat and ready to load other flat goods. The entire rotation process is simple and convenient, requiring no complex mechanical structures.

[0027] Furthermore, the raised floor 3 is connected to the bottom crossbeam 11 or the fixed floor 2 via a flexible connector.

[0028] Furthermore, the raised floor 3 is connected to the bottom beam 11 or the fixed floor 2 via a flexible connector. This flexible connector can be a flexible component such as a wire rope, nylon rope, or chain. During transportation and use, the flexible connector remains connected to prevent the raised floor 3 from being lost. When the pad 4 is needed, workers use the lifting device 5 to lift and flip the raised floor 3; the good bending performance of the flexible connector does not affect the flipping operation. This flexible connection method ensures the connection between the raised floor 3 and the bottom beam 11 or the fixed floor 2, preventing loss, while also allowing for flexible flipping during use.

[0029] For further details, please refer to... Figures 7-8 The raised floor 3 has pads 4 on one surface, which are spaced apart along the length of the raised floor 3; the raised floor 3 has a lifting member 5 on the other surface, which is placed in a groove on the other surface.

[0030] Specifically, the pad 4 refers to a structural component used to support rolled goods and form a regularly distributed array of support points. It can be implemented using a raised structure made of metal, high-strength plastic, or composite materials. The spaced arrangement provides evenly distributed support force, preventing stress concentration when the goods roll. The lifting component 5 refers to a gripping component used to operate the opening and closing of the raised floor 3. It can be in the form of an embedded handle, a ring handle, or a strip-shaped grip. The groove is a hidden receiving space designed to protect the lifting component 5. It can be achieved by creating rectangular grooves, arc grooves, or other shaped recessed areas on the surface of the raised floor 3, maintaining the flatness of the base frame surface while protecting the lifting component 5 from external impacts.

[0031] By setting pads 4 spaced along the length of one surface of the raised floor 3, the pads 4 can form a dynamically adaptable array of support points according to the arc characteristics of the rolled goods. This layout specifically considers the contact requirements of goods with different diameters, allowing the supporting force to be evenly transmitted to the bottom crossbeam structure. Simultaneously, a lifting component 5 with grooved protection is set on the other surface of the raised floor 3, which not only solves the problem of the lifting component 5 being easily damaged by goods collisions, but also simplifies the gripping action during operation through its concealed design. The raised floor 3, together with the fixed floor 2 and the bottom crossbeam assembly 1, constitutes a complete support system, effectively securing the rolled goods, improving operational convenience, and effectively reducing the risk of jamming during vertical lifting.

[0032] Furthermore, the surface of the pad 4 perpendicular to the raised floor 3 is provided with an embedded handle 42 for lifting and placing the raised floor 3. Specifically, when the surface with the pad 4 is placed upwards, the raised floor 3 can be lifted by pulling the pad 4 when it is necessary to reverse it.

[0033] In another possible embodiment of this utility model, the surface of the raised floor 3 with pads 4 may also be provided with a pull member that is the same as the lifting member 5. The pull member may be provided in the middle of the two pads 4 or on both sides of the two pads 4.

[0034] Furthermore, each of the pad blocks 4 is provided with at least one support surface 41 for supporting rolled goods.

[0035] Furthermore, the support surface 41 is inclined from the top of the pad 4 toward the movable floor 3.

[0036] Specifically, the support surface 41 refers to a dedicated area on the pad block 4, a surface structure used to directly contact the rolled goods and provide support. It can be implemented using a curved surface, a sawtooth surface, or an inclined plane. The purpose of the inclined setting is to optimize the force distribution on the goods through angle design, thereby enhancing the fixing effect.

[0037] By integrating a support surface 41 onto the pad block 4, and using the pad block 4 as a basic carrier, a dedicated support area is designed for the cylindrical contour of rolled goods. The support surface 41 is directly set on the surface of the pad block 4, allowing the goods to naturally embed into the recessed or inclined structure formed by the support surface 41 when placed, effectively reducing the relative sliding between the goods and the support surface 41. Based on this, the operation of the raised floor 3 is simpler, allowing workers to secure the goods without multiple people working together, thus more stably preventing the rolled goods from rolling and shifting during transportation. Furthermore, the support surface 41 can be adjusted to accommodate the stable load-bearing requirements of goods of different sizes.

[0038] The inclined design of the support surface 41 optimizes the securing mechanism for rolled goods. In practical applications, when rolled goods are placed between adjacent support surfaces 41, their own weight and the inertial force during transportation work together to cause the goods to slide naturally along the inclined surface towards the movable floor 3, thereby dynamically forming a V-shaped clamping area between adjacent support surfaces 41. At the same time, the inclined structure avoids reliance on additional complex mechanisms, simplifies the overall structure of the underframe, reduces operational difficulty and maintenance costs, and maintains stability and reliability during transportation.

[0039] For further details, please refer to... Figures 1-2 The raised floor 3 includes a first raised floor 31 and a second raised floor 32 spliced ​​along the length of the bottom crossbeam group 1; the first raised floor 31 and the second raised floor 32 are symmetrically arranged.

[0040] Specifically, in this embodiment, a single movable floor 3 is divided into a first movable floor 31 and a second movable floor 32 along its length. The purpose of this segmented design is to reduce the difficulty of a single operation. The two movable floor 3 have the same structure and material, and their symmetrical arrangement allows them to align naturally during installation, thereby forming a stable support interface.

[0041] By designing the raised floor 3 as a segmented, symmetrical structure, the problems of inconvenience in operation and poor adaptability of the integral raised floor 3 are effectively solved. The first raised floor 31 and the second raised floor 32, as independent operating units, can be vertically pulled up or flipped up separately, avoiding the cumbersome steps required by the traditional integral raised floor 3 to operate simultaneously, simplifying the opening and closing process and reducing operational intensity. Furthermore, through symmetrical arrangement, the two raised floor sections 3 can naturally align during installation, forming a uniform distribution of support force, which is particularly suitable for fixing rolled goods of different sizes, enhancing the flexibility and reliability of the structure.

[0042] For further details, please refer to... Figures 1-2 The supporting surfaces 41 of adjacent pads 4 on the first movable floor 31 or the second movable floor 32 are arranged opposite each other to form a first fixed area 411.

[0043] The supporting surfaces 41 of the adjacent pads 4 of the first movable floor 31 and the second movable floor 32 are arranged opposite each other to form a second fixed area 412.

[0044] Through the ingenious arrangement of the support surfaces 41 of the pads 4, two different fixing areas are formed to accommodate steel coils 6 of different sizes. Specifically, on a single movable floor 3 (first movable floor 31 or second movable floor 32), the support surfaces 41 of two adjacent pads 4 are arranged opposite each other, forming a first fixing area 411 between the two support surfaces 41. Please refer to... Figure 9Since there is a certain gap between the two pads 4 on the single movable floor 3, the opening of the first fixing area 411 is relatively small, which is suitable for fixing steel coils 6 with smaller diameters.

[0045] Please refer to Figure 10 Because the first movable floor 31 and the second movable floor 32 are symmetrically arranged, the supporting surfaces 41 of the adjacent pads 4 on both sides of the splicing point are also positioned opposite each other after splicing, forming a second fixing area 412 at the center line of the two movable floor 3s. The second fixing area 412 is composed of the supporting surfaces 41 of the pads 4 from the two different movable floor 3s, and its opening is relatively large, suitable for fixing steel coils 6 with larger diameters. This dual fixing area design allows the container chassis to accommodate the loading of steel coils 6 of various specifications simultaneously without the need to replace or adjust the position of the pads 4, improving the versatility and ease of use of the chassis.

[0046] Furthermore, the support surface 41 is a curved or sawtooth surface.

[0047] Specifically, the support surface 41 can be implemented using a curved surface structure that conforms to the shape characteristics of rolled goods, or it can be implemented using a planar structure with a serrated texture. The purpose of the curved surface design is to form a continuous and uniform contact area based on the arc shape characteristics of the rolled goods, thereby effectively dispersing pressure and avoiding local stress concentration; the purpose of the serrated surface design is to increase the friction coefficient by increasing the surface roughness, thereby enhancing the ability to fix goods on smooth surfaces.

[0048] The curved support surface 41 can closely conform to the surface contour of rolled goods, suppressing the tendency of goods to roll during transportation vibrations. The serrated support surface 41, with its unique serrated texture structure, significantly increases surface roughness, especially for rolled goods with smooth surfaces, firmly gripping the goods under vibration or bumpy conditions to prevent slippage and displacement. These designs collectively optimize the function of the support surface 41, keeping the goods stably fixed on the container rack.

[0049] Furthermore, the raised floor 3 is made of wood or a composite material.

[0050] Among them, wood materials are natural timber or processed wood-based panels, which have low density and good processing performance; composite materials are composed of two or more different materials, which can balance the requirements of strength and lightweight. The purpose of introducing wood materials or composite materials is to reduce the overall weight of the raised floor 3, thereby optimizing the ease of operation and reducing the load on the hinge mechanism.

[0051] In practical applications, wood or composite materials, due to their lower density, can effectively replace traditional metal structures while maintaining sufficient strength and support function. This material choice allows workers to easily lift and move the raised floor without additional assistance, avoiding the drawbacks of requiring multiple people to work together due to excessive weight. At the same time, the lighter weight reduces the load on the hinge mechanism, lowers the probability of jamming during opening and closing, and simplifies daily maintenance procedures.

[0052] Example 2 This embodiment provides a container, including a container frame as described in any of the preceding embodiments.

[0053] In summary, the container chassis provided in this embodiment effectively improves upon the problems of traditional steel coil container flip-tops being cumbersome, complex to operate, and costly through its innovative movable floor and fixed floor separation structure. The movable floor features a double-sided design: one side has pads for securing the steel coils, and the other side has lifting mechanisms for easy operation. The pads can be easily exposed or hidden by simply flipping the floor 180 degrees, eliminating the need for complex hinge mechanisms. Operation is simple and quick, and can be completed by a single person. The movable floor can be made of lightweight materials such as wood, reducing weight and cost. By forming a first fixed area and a second fixed area within each movable floor panel and at the joint between two panels, it can accommodate the loading requirements of steel coils of different diameters, improving the chassis's versatility.

[0054] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
