[0002] As an international general traffic logistics transport tool of multimodal transport, the application field of container is more and more extensive. When transporting large solid goods such as ore and glass by using container, there are usually three limiting ways. The first way is to place steel seat frame in the box body to fix the goods by the steel seat frame. The second way is to reduce the impact of goods and goods, goods and box body by buffer beam. The third way is to reduce the impact of goods and goods, goods and box body by filling foamed material. The above three ways all have disadvantages. The steel seat frame is inconvenient to use. The ways of installing buffer beam and filling foamed material are all when transporting large solid goods, the impact force generated by large solid goods acts on the inner wall of the side wall or end wall of the container, which is easy to cause the container to overturn.

[0055] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0056] The preferred embodiments of this utility model will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0057] In this document, ordinal numbers such as “first” and “second” used in this invention are merely identifiers and do not include any other meaning, such as a specific order.

[0058] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may also include other embodiments.

[0059] First Implementation Method

[0060] This utility model provides a chassis. The chassis is used for a container. The container includes a body. The body includes a chassis, side walls, end walls, and end doors. The chassis, side walls, end walls, and end doors are generally rectangular parallelepiped structures. The chassis is equipped with a limiting sleeve assembly 120. When the container is used to transport large solid cargo such as ore and glass, the large solid cargo is placed on the chassis. At this time, the movement of the large solid cargo can be blocked by the limiting sleeve assembly 120. For example, the rod of the blocking member passes through the limiting sleeve assembly 120. In this way, the movement of the large solid cargo can be blocked by the blocking member. The rod is located at the lower end of the blocking member.

[0061] Please refer to Figures 1 to 11 The base frame includes a bottom side beam 112 and a bottom end beam. The length direction of the bottom side beam 112 (the length direction of the base frame) is perpendicular to the length direction of the bottom end beam (the width direction of the base frame). The ends of the bottom side beam 112 are connected to the ends of the bottom end beam to form a generally rectangular bottom frame.

[0062] like Figure 1As shown, the underframe also includes corner brackets. These corner brackets are located at the corners of the bottom frame. This allows the container to be secured using the corner brackets.

[0063] like Figure 3 and Figure 4 As shown, the base frame also includes a bottom crossbeam 111. The length direction of the bottom crossbeam 111 is parallel to the length direction of the bottom end beams. Along the length direction of the base frame, the bottom crossbeam 111 is located between two bottom end beams. Along the width direction of the base frame, the bottom crossbeam 111 is located between two bottom side beams 112. One end of the bottom crossbeam 111 is connected to one bottom side beam 112. The other end of the bottom crossbeam 111 is connected to the other bottom side beam 112.

[0064] The underframe also includes reinforcing longitudinal beams 113. The longitudinal direction of the reinforcing longitudinal beams 113 intersects (e.g., perpendicularly to) the longitudinal direction of the bottom crossbeams 111. Along the length of the underframe, the reinforcing longitudinal beams 113 are located between two adjacent bottom crossbeams 111. One end of the reinforcing longitudinal beam 113 is connected to one bottom crossbeam 111. The other end of the reinforcing longitudinal beam 113 is connected to the other bottom crossbeam 111. Thus, the reinforcing longitudinal beams 113 increase the strength of the underframe.

[0065] Optionally, the bottom crossbeam 111 has flanges and a web. The end of the reinforcing longitudinal beam 113 is connected to the web. Thus, the connection between the bottom crossbeam 111 and the reinforcing longitudinal beam 113 is secure.

[0066] like Figures 2 to 8 As shown, the underframe also includes a limiting sleeve assembly 120. The limiting sleeve assembly 120 is constructed as a column. The limiting sleeve assembly 120 has a top opening 124 and a limiting inner cavity 123 communicating with the top opening 124. The length direction of the limiting sleeve assembly 120 extends along the height direction of the bottom crossbeam 111. The limiting sleeve assembly 120 passes through the reinforcing longitudinal beam 113. The limiting sleeve assembly 120 is connected to the reinforcing longitudinal beam 113. Thus, the lower end of the rod can pass through the top opening 124 into the limiting inner cavity 123, so that the blocking member is fixed to the reinforcing longitudinal beam 113, thereby enabling it to be used to block large solid goods placed on the underframe. For example, it can block the movement of large, fixed goods along the length direction of the underframe.

[0067] It is understandable that, in some cases, blocking components can also be used to prevent the movement of large solid goods along the width of the underframe.

[0068] The limiting sleeve assembly 120 is installed through the reinforcing longitudinal beam 113. Compared with the existing technology where the limiting parts are welded to the top surface of the bottom crossbeam or the top surface of the floor, the connection strength between the limiting sleeve assembly 120 and the reinforcing longitudinal beam 113 is greater and less prone to damage.

[0069] Optionally, such as Figure 8As shown, the reinforcing longitudinal beam 113 can be rectangular steel. The rectangular steel includes an upper plate 117, a lower plate 118, and two side plates 119. The upper plate 117, lower plate 118, and two side plates 119 form a rectangular structure. The limiting sleeve assembly 120 passes through the upper plate 117 and the lower plate 118. In this way, the limiting sleeve assembly 120 is welded to the rectangular steel at the upper plate 117 and the lower plate 118. The welding amount between the limiting sleeve assembly 120 and the reinforcing longitudinal beam 113 is small, which facilitates processing.

[0070] In this embodiment, the reinforcing longitudinal beam 113 is connected to the bottom crossbeam 111, which can increase the strength of the base frame; the limiting sleeve assembly 120 passes through the reinforcing longitudinal beam 113, and the connection strength between the limiting sleeve assembly 120 and the reinforcing longitudinal beam 113 is high and not easily damaged; in addition, the welding amount between the limiting sleeve assembly 120 and the reinforcing longitudinal beam 113 is small, which is convenient for processing and has small welding deformation.

[0071] Optionally, such as Figure 7 and Figure 8 As shown, the limiting sleeve assembly 120 includes a body 121 and a base plate 122. The body 121 is constructed as a circumferentially closed annular structure. For example, the body 121 is a cylindrical sleeve structure. The base plate 122 is connected to the bottom end of the body 121. The base plate 122 closes the bottom end of the body 121 to form a limiting cavity 123. The body 121 passes through the upper plate 117 and lower plate 118 of the reinforcing longitudinal beam 113. Thus, the limiting sleeve assembly 120 has a simple structure. In addition, the base plate 122 can increase the strength of the body 121.

[0072] Alternatively, please continue to refer to Figure 7 and Figure 8 The top end of the body 121 extends above the reinforcing longitudinal beam 113. The bottom end of the body 121 extends below the reinforcing longitudinal beam 113. Thus, the portion of the body 121 above the reinforcing longitudinal beam 113 can be circumferentially welded to the upper plate 117 of the reinforcing longitudinal beam 113. The portion of the body 121 below the reinforcing longitudinal beam 113 can be circumferentially welded to the lower plate 118 of the reinforcing longitudinal beam 113. This facilitates the welding of the body 121 to the reinforcing longitudinal beam 113. Furthermore, the weld strength between the body 121 and the reinforcing longitudinal beam 113 is high.

[0073] Optionally, such as Figure 7 and Figure 8 As shown, the base frame also includes a floor 116. The floor 116 can be a steel floor. The floor 116 is laid on the bottom crossbeam 111. Large solid goods can be placed on the floor 116. The floor 116 has a limiting hole 151. The limiting hole 151 is located at the top opening 124. In this way, the rod can pass through the base plate 122 and the body 121.

[0074] Furthermore, the floor 116 is fitted onto the top of the body 121. Therefore, when the top of the body 121 is subjected to significant deformation, the floor 116 prevents the top of the body 121 from moving. Additionally, the limiting hole 151 can avoid the welded joint between the top of the body 121 and the upper plate 117.

[0075] Furthermore, the top surface of the floor 116 is flush with the top surface of the main body 121. This prevents the main body 121 from protruding above the base plate 122 and avoids large solid goods from bumping into the main body 121.

[0076] Optionally, such as Figure 2 and Figure 4 As shown, the base frame also includes a reinforcing crossbeam 114. The length direction of the reinforcing crossbeam 114 is parallel to the length direction of the bottom crossbeam 111. The reinforcing crossbeam 114 and the bottom crossbeam 111 are spaced apart. The end of the reinforcing crossbeam 114 is connected to the reinforcing longitudinal beam 113. A portion of the reinforcing crossbeam 114 is located between the adjacent reinforcing longitudinal beam 113 and the bottom side beam 112, and is connected to the bottom side beam 112. This further increases the strength of the base frame at the limiting sleeve assembly 120.

[0077] Furthermore, along the length of the reinforcing longitudinal beam 113, a reinforcing crossbeam 114 is provided at least partially at the location of the limiting sleeve assembly 120. This results in greater strength at the limiting sleeve assembly 120 of the base frame.

[0078] Furthermore, along the length of the reinforcing longitudinal beam 113, a portion of the reinforcing longitudinal beam 113 has at least two limiting sleeve assemblies 120. Thus, the rod portion of the blocking member can be positioned in different limiting sleeve assemblies 120 to block large, fixed goods of different sizes.

[0079] Optionally, such as Figure 7 and Figure 8 As shown, the floor 116 overlaps with the reinforcing longitudinal beam 113. At this point, the top surface of the reinforcing longitudinal beam 113 is flush with the top surface of the bottom crossbeam 111. Thus, the structure of the base frame is simple.

[0080] Optionally, such as Figures 1 to 3 As shown, the underframe also includes a forklift slot 115. Thus, the underframe or containers using the underframe can be transported via the forklift slot 115.

[0081] This utility model also provides a container. The container includes a body. The body includes the aforementioned base frame.

[0082] In this embodiment, the container includes the aforementioned underframe, and the reinforcing longitudinal beam 113 is connected to the bottom crossbeam 111, which can increase the strength of the underframe; the limiting sleeve assembly 120 passes through the reinforcing longitudinal beam 113, and the connection strength between the limiting sleeve assembly 120 and the reinforcing longitudinal beam 113 is high and not easily damaged; in addition, the welding amount between the limiting sleeve assembly 120 and the reinforcing longitudinal beam 113 is small, which is convenient for processing and has small welding deformation.

[0083] Optionally, such as Figure 1 , Figure 9 and Figure 10 As shown, the container has corner posts 130 located at the corners and corner brackets 131 located at the top of the corner posts 130. The container includes a lintel 132 and a pivot 140. The lintel 132 is located at the top of the end of the container where the end door is located. The corner bracket 131 is provided with a mounting portion. The mounting portion has a first mounting hole. The end of the lintel 132 has a second mounting hole. The pivot 140 is detachably passed through the first and second mounting holes so that both ends of the lintel 132 are rotatably connected to the corner bracket 131 via the pivot 140. At this time, the axial direction of the pivot 140 is parallel to the height direction of the underframe (that is, the height direction of the bottom crossbeam 111). Thus, by removing the pivot 140 at one end of the lintel 132, the lintel 132 can be rotated about the pivot 140 located at the other end of the lintel 132. The lintel 132 can be rotated to a position where the length of the lintel 132 is parallel to the length of the base frame.

[0084] Please continue to refer to this. Figure 1 , Figure 9 and Figure 10 The container also has a top beam and a top side beam 133 at its top. When the lintel 132 connects to the two corner pieces 131, the length direction of the top beam is parallel to the length direction of the lintel 132. Along the length direction of the base frame, the lintel 132 is located at one end of the container. The top beam is located at the other end of the container. Along the width direction of the base frame, the top side beam 133 is located at the end of the container. The top beam, the top side beam 133, and the lintel 132 form a roughly rectangular top frame. When the lintel 132 connects to the two corner pieces 131, the top frame forms a top opening 152. In this way, large solid goods can be loaded and unloaded through the top opening 152.

[0085] If the height of the goods is relatively large and the size is fixed, a pivot 140 can be removed, and then the lintel 132 can be rotated. At this time, large solid goods can be loaded and unloaded through the end door of the container.

[0086] It is understood that, in embodiments not shown, the lintel can be connected to the corner post via a pivot.

[0087] Optionally, such as Figure 9 and Figure 10As shown, the container also includes a chain 150. One end of the chain 150 is connected to the corner piece 131. The other end of the chain 150 is connected to the pivot shaft 140. This prevents the pivot shaft 140 from being lost.

[0088] Optionally, the length of the container along the base frame is 6058 mm. The width of the container along the base frame is 2550 mm. The height of the container along the base frame is 2896 mm. For example, the container can be a 20-foot standard container.

[0089] Furthermore, such as Figure 11 As shown, the dimension D1 of the gap between the two top side beams 133 ranges from 2340mm to 2350mm along the width direction of the base frame. For example, 2344mm. This facilitates loading and unloading of goods.

[0090] Optionally, there may be multiple floorboards 116. Multiple floorboards 116 are spliced ​​together and laid on the bottom crossbeam 111.

[0091] Second Implementation Method

[0092] In the second implementation method, please refer to Figures 12 to 14 There is a gap between the floor 216 and the reinforcing longitudinal beam 213. At this time, the top surface of the reinforcing longitudinal beam 213 is located below the top surface of the bottom crossbeam. The base frame also includes a reinforcing plate 260. The reinforcing plate 260 is laid within the gap between the floor 216 and the reinforcing longitudinal beam 213. The reinforcing plate 260 is welded to the top surface of the reinforcing longitudinal beam 213. This further increases the strength of the base frame at the limiting sleeve assembly.

[0093] The other settings of the second embodiment are largely the same as those of the first embodiment, and will not be described in detail here.
