[0061] It should be noted that the terms “up,” “down,” “front,” “back,” “left,” “right,” “inner,” “outer,” and similar expressions used in this article are for illustrative purposes only and are not intended to be restrictive.
[0062] This utility model provides a container chassis and a container.
[0063] Now, refer to the appendix Figures 1 to 4 Exemplary embodiments according to the present invention will be described in more detail below.
[0064] The container chassis 100 includes a chassis frame 10, at least two floor panels 13, and a bottom cover 14. The floor panels 13 are located above the chassis frame 10 and connected to it. The bottom cover 14 is located below the chassis frame 10 and connected to it.
[0065] To enable the container base frame 100 to drain liquid, the container base frame 100 also includes a drain trough 20 and a drain pipe 30. The drain trough 20 is connected to two adjacent floor panels 13 with its opening facing upwards, and the top surface of the drain trough 20 is not higher than the top surface of the floor panel 13, so as to guide the liquid on the floor panel 13 to the drain trough 20.
[0066] The drain pipe 30 is connected to the drain tank 20 to drain the liquid in the drain tank 20. Specifically, the drain tank 20 has a drain hole 25 at the bottom of the tank, and the top of the drain pipe 30 is connected to the drain hole 25 and is not higher than the drain hole 25, so that the accumulated liquid in the drain tank 20 can be drained completely, and the residual liquid is prevented from accelerating the corrosion of the drain tank 20.
[0067] The bottom cover plate 14 is provided with an opening, and the bottom end of the drain pipe 30 extends through the opening of the bottom cover plate 14, that is, the drain pipe 30 passes through the drain tank 20 and the bottom cover plate 14. Thus, the liquid in the drain tank 20 is discharged into the container base frame 100 through the drain pipe 30 downward through the bottom cover plate 14.
[0068] It should be noted that the directions such as "up" and "down" in this application refer to the directions defined by the container base 100 in its normal placement state. Specifically, the up and down direction is the height direction D3 of the container base 100.
[0069] According to this utility model, the container underframe features drainage channels located beneath the floor, facilitating the flow of surface water to these channels. The container underframe is constructed with multiple floor panels, and the drainage channels are positioned between adjacent panels, allowing for flexible arrangement of the number and location of the channels based on the floor layout. Furthermore, the layout of the floor panels, the number of drainage channels, and their installation positions can be customized according to the specific usage requirements and internal layout of the container. Compared to drainage channels located on the outermost edge of the underframe, this design offers higher overall drainage efficiency. For example, if a small amount of liquid accumulates in a localized area of the container underframe, it can be quickly drained through the drainage channels between the floor panels, rather than waiting for the liquid to accumulate and flow to one end or side of the underframe. Moreover, this design requires minimal modification to the underframe's planar structure and does not affect its load-bearing capacity.
[0070] The underframe 10 includes bottom side beams 11 and bottom crossbeams 12. The bottom side beams 11 extend along the length direction D1 of the container underframe 100, and two bottom side beams 11 are arranged in parallel. The bottom side beams 11 can be I-beams, square tubing, channel steel, or bent parts. The bottom crossbeams 12 connect the two bottom side beams 11, and multiple bottom crossbeams 12 are spaced apart along the length direction D1. The bottom crossbeams 12 include a bottom end beam located at the outermost end of the container underframe 100 along the length direction D1. The bottom crossbeams 12 are integrally formed channel steel, bent parts, square tubing, or angle steel. For example, the bottom crossbeams 12 are U-shaped and include connected upper plates, lower plates, and vertical plates.
[0071] Floor 13 connects to bottom crossbeam 12 and bottom side beam 11. Floor 13 is preferably flush with the top surface of bottom side beam 11. It should be noted that floor 13 may be spaced only in the width direction D2 of the container, spaced only in the length direction D1 of the container, or spaced simultaneously in both the length direction D1 and the width direction D2 of the container. Container base frame 100 may only have drainage channels 20 extending along the width direction D2 of the container base frame 100, may only have drainage channels 20 extending along the length direction D1 of the container base frame 100 (not shown in the figure), or may have drainage channels 20 extending along both the length direction D1 and the width direction D2 of the container.
[0072] For example, at least two floor panels 13 are spaced apart along the length direction D1 of the container underframe 100. A drain trough 20 extends along the width direction D2 of the container underframe 100 and connects between two adjacent floor panels 13 along the length direction D1 of the container.
[0073] For example, at least two floor panels 13 are spaced apart in the width direction D2 of the container underframe 100. A drain trough 20 extends along the length direction D1 of the container underframe 100 and connects between two adjacent floor panels 13 in the width direction D2 of the container.
[0074] For example, at least two floor panels 13 are spaced apart along the length direction D1 of the container base 100, and at least two floor panels 13 are spaced apart along the width direction D2 of the container base 100. The container base 100 includes only drainage channels 20 extending along the width direction D2 of the container base 100, or the container base 100 includes only drainage channels 20 extending along the length direction D1 of the container base 100, or the container base 100 includes drainage channels 20 extending along both the width direction D2 and the length direction D1 of the container base 100.
[0075] The drainage trough 20, extending along the width direction D2 of the container, is preferably set to have a length substantially the same as the dimension of the floor 13 in the width direction D2 of the container base frame 100. Preferably, both ends of the drainage trough 20 are also fixedly connected to the bottom side beam 11, so that the drainage trough can also serve as a reinforcing rib like the bottom crossbeam 12.
[0076] The drain trough 20, which extends along the length direction D1 of the container, is set between two adjacent bottom crossbeams 12 to avoid interference with the bottom crossbeams 12, meaning its length does not exceed the distance between the two adjacent bottom crossbeams 12.
[0077] The drainage trough 20 includes a bottom wall 21, side walls 22, and fixing parts 23. The two side walls 22 are respectively connected to both sides of the bottom wall 21 to form a trough shape. The two fixing parts 23 are respectively connected to the ends of the two side walls 22 away from the bottom wall 21, and the two fixing parts 23 extend horizontally to both sides. The two fixing parts 23 are respectively fixedly connected to the lower sides of the edges of two adjacent floor panels 13. The drainage trough is lower than the surface of the floor panels 13, eliminating the need for additional inclined surfaces to guide liquid flow onto the floor panels 13.
[0078] Preferably, the top of the drain pipe 30 is slightly lower than the bottom surface of the drain tank 20. The drain pipe 30 is connected to the drain tank 20 and the bottom sealing plate 24 by welding.
[0079] The drain tank 20 also includes a sealing plate 24, which is located at both ends of the drain tank 20 in the extending direction. The sealing plate 24 is fixedly connected to the drain tank 20 to form the end walls at both ends of the drain tank 20, so as to prevent the base frame 10 from contacting the liquid in the drain tank 20 and being corroded.
[0080] Optionally, the sealing plate 24 is fixedly connected to the drain tank 20 and to at least one of the base frame 10 and the floor. In this way, the connection between the drain tank 20 and the sealing plate 24 is more robust and secure.
[0081] For example, the sealing plate 24 is connected to the drain trough 20 and to the floor 13. For example, for the drain trough 20 extending along the width direction D2 of the container underframe 100, the sealing plate 24 is connected to the drain trough 20 and to the bottom side beam 11. For example, for the drain trough 20 extending along the width direction D2 of the container underframe 100, the sealing plate 24 is connected to the drain trough 20 and to the bottom side beam 11 and the floor 13.
[0082] For example, for a drain trough 20 extending along the length direction D1 of the container underframe 100, a sealing plate 24 is connected to the drain trough 20 and to the bottom crossbeam 12. For example, for a drain trough 20 extending along the length direction D1 of the container underframe 100, a sealing plate 24 is connected to the drain trough 20 and to the bottom crossbeam 12 and the floor 13.
[0083] The sealing plate 24 can be connected to the drain tank 20 and the base frame 10 by welding.
[0084] Optionally, each drainage tank 20 is connected to at least two drainage pipes 30, and the at least two drainage pipes 30 are arranged at a predetermined distance along the extension direction of the drainage tank 20, so that the drainage efficiency is high.
[0085] The container underframe 100 also includes a cover plate that detachably covers the opening of the drain trough 20. For example, the cover plate overlaps the fixing part 23 of the drain trough 20. Preferably, the cover plate covers the opening of the drain trough 20, and the upper surface of the cover plate is flush with the upper surface of the floor 13. Preferably, when the cover plate is closed in the opening of the drain trough 20, the dimension of the cover plate perpendicular to the extension direction of the drain trough 20 is substantially equal to the distance between the cover plate and the floor 13 on both sides, that is, there is essentially no gap between the cover plate and the floor 13 on both sides when closed. Thus, the upper surface of the container underframe 100 is flat overall, and the arrangement inside the container is not affected by the installation of the drain trough 20.
[0086] The cover can be flat, allowing the drainage tank 20 to be used selectively. Thus, the cover can be placed over all or part of the drainage tank 20 that is not in use, and the cover can be opened when needed.
[0087] Optionally, the cover plate can be detachably placed over the opening of the drain pipe 30, making the drain tank 20 easy to clean.
[0088] Preferably, the cover plate has perforated holes. Thus, while the drain tank 20 is in normal use, the upper surface of the container base frame 100 remains flat, and it also prevents other debris from entering the drain tank 20 and clogging the opening of the drain pipe 30.
[0089] The floor 13 is made of steel or wood. When the floor 13 is made of steel, the sealing plate 24, drainage trough 20, and base frame 10 can be connected to the floor 13 by welding. For example, the drainage trough 20 is connected to the floor 13 by intermittent welding. For example, the steel floor 13 has multiple sets of plug weld holes, and is fixedly connected to multiple bottom beams 12 by welding at the plug weld holes, reducing the weld length between the floor 13 and the bottom beams 12, thereby reducing the deformation of the floor 13. The floor panels 13 can be fixedly connected to each other by welding.
[0090] When the floor 13 is a wooden floor 13, the sealing board 24, the drainage channel 20, and the base frame 10 can be connected to the floor 13 via connectors. For example, the drainage channel 20 and the wooden floor 13 can be connected using self-tapping screws, rivets, etc., and sealed using sealant, adhesive strips, etc.
[0091] Optionally, multiple bottom cover plates 14 are arranged along the length direction D1 of the container underframe 100. The bottom cover plates 14 are respectively connected to two bottom side beams 11 at both ends of the width direction D2 of the container underframe 100; the bottom cover plates 14 are fixedly connected to each other at the ends of the length direction D1 of the container underframe 100.
[0092] The ends of any two adjacent bottom end plates 24 are fixedly connected. The connection between any two adjacent bottom end plates 24 is an intermittent welding process. That is, the welding between two adjacent bottom end plates 24 is performed through the gap between the plates and using an intermittent welding method. This method can effectively reduce welding deformation of the bottom end plates 24, reserve space for welding deformation, and ensure the welding quality and flatness of the base frame structure.
[0093] Insulation materials, such as rock wool, glass wool, and foam, are filled between the floor 13 and the bottom cover 14. Thus, the container frame 100 provides both insulation and drainage functions, meeting the special needs of rainy and low-temperature regions.
[0094] This utility model also provides a container, which includes the container frame 100 described above.
[0095] According to this utility model, the floor and drainage trough of the underframe of the container can be laid out according to specific needs, with flexible design, high drainage efficiency, and adaptability to rainy and low-temperature environments.
