Description

Technical Field

[0001] The utility model relates to the technical field of container production, and more specifically, to a reinforced chassis. Background Art

[0002] In order to meet the load-bearing capacity for loading goods, the existing container chassis is provided with 5 to 6 bottom crossbeam structures in a common chassis to enhance the overall stiffness and stability of the chassis. The connecting plate at the rear end is used to connect the chassis and the rear frame. Some special customers have higher requirements for the load-bearing capacity of the container and need 7 to 8 bottom crossbeams to further enhance the resistance of the container.

[0003] As shown in Figure 3 and Figure 4 of the specification drawings, at the end of the inner floor of the box, it is connected to the rear door part of the box through the rear connecting plate. The existing connecting plate has a relatively shallow straight groove structure at the bottom. This type of container chassis has limitations in the overall layout and it is difficult to meet the setting of 7 to 8 bottom crossbeams. At the same time, the rear end of the container is often used as the forklift insertion point and is easily damaged. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a reinforced chassis to solve one or more of the above problems.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] The reinforced chassis includes a T-shaped floor and a door connected in a right-angle structure, and is characterized in that: the T-shaped floor and the door are connected through a chassis plate and a connecting plate, and an integrally formed bottom crossbeam is further provided on the bottom surface of the end of the connecting plate.

[0007] Further, the cross-section of the bottom crossbeam is an inverted trapezoid structure, and the depth of the bottom crossbeam is not less than half of the height difference between the T-shaped floor and the corner seat of the door.

[0008] Further, the chassis plate is a wavy plate surface structure, and the length between adjacent wave crests and wave troughs is reduced to adapt to the addition of the bottom crossbeam.

[0009] Further, the end of the chassis plate is provided with a downwardly folded tail support, and the tail support is butt-jointed and fixed to the end of the bottom crossbeam.

[0010] Further, at least 6 to 7 basic crossbeams are evenly distributed on the bottom of the chassis plate, and the basic crossbeams have the same structure and size as the bottom crossbeam.

[0011] Further, a plurality of different types of rubber strips are provided between the door and the corner seat, and the open ends of the rubber strips are arranged inward.

[0012] In summary, the utility model has the following beneficial effects: By using an integrally formed bottom crossbeam to replace the straight groove structure design of the original rear connecting plate, not only the structural strength at the rear door of the box is enhanced, but also the layout limitations are eliminated. On the premise of keeping the box size unchanged, the number of bottom crossbeams can be adjusted, and the damage to the structure of the rear part of the container caused by the frequent entry and exit of forklifts is also avoided.

[0018] The following further elaborates on the utility model in detail Figure 1-2 with reference to the attached drawings.

[0019] The strengthened chassis, as Figure 1 and Figure 2 shown, except for the conventional structure of the overall container, is mainly distinguished in the connection relationship between the T-shaped floor 1, the door 2, the chassis plate 3 and the connecting plate 4 and the improvement of the corresponding components. The main body of the strengthened chassis is the T-shaped floor 1 and the door 2 which are fixedly connected, and the two form the circumferential angle of the box, generally a structure of a ninety-degree right angle. The T-shaped floor 1 and the door 2 are connected through the chassis plate 3 and the connecting plate 4. Specifically, the T-shaped floor 1 is integrally laid on the chassis plate 3, the connecting plate 4 is arranged at the end of the chassis plate 3, and the end of the connecting plate 4 is further connected to the door 2. It can be understood that the chassis plate 3 is connected to the door 2 through the connecting plate 4, and the T-shaped floor 1 is laid on the chassis plate 3. The bottom surface of the end of the connecting plate 4 is improved, and the original straight groove structure is replaced with an integrally formed bottom crossbeam 5. Different types and structures of rubber strips are arranged between the door 2 and its corner seat 6 to ensure the internal sealing performance.

[0020] The cross section of the bottom cross beam 5 is an inverted trapezoidal structure. The depth of the bottom cross beam 5 should be much greater than the depth of the existing straight groove. The bottom of the container is the limit, and the minimum should not be less than half of the height difference between the T-shaped floor 1 and the knife box door 2 corner seat 6. This is for the sake of structural strength. The bottom frame plate 3 is a wavy plate structure. When the overall size of the container remains unchanged, the distance between adjacent wave crests and wave valleys is reduced compared to the existing container bottom frame, so as to adapt to the difference between the bottom cross beam 5 added at the end and the width of the existing straight groove.

[0021] The bottom of the bottom frame plate 3 is provided with a folded tail stock 7, which is fixedly connected to the end of the bottom cross beam 5. There are at least 6 to 7 basic cross beams evenly distributed at the bottom of the bottom frame plate 3. The structural dimensions of the basic cross beams are generally consistent with the bottom cross beam 5, and fine adjustments can also be made to ensure that there are at least 7 to 8 cross beams at the bottom of the entire box.

[0022] The present application improves the straight groove part, optimizes it and deletes it and directly replaces it with the bottom cross beam 5, which not only eliminates the structural design limitations brought by the layout, can effectively meet the high requirements of customers for customization, but also can enhance the structural strength of the tail end and reduce the wear caused by the use of forklifts.

[0023] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
