Description

Technical Field

[0001] This utility model relates to the field of container technology, specifically to a slot reinforcement structure for an overweight container. Background Technology

[0002] Containers have become a standard international transport tool for multimodal transport. A typical 20-foot container is equipped with a slot for easy movement or stacking. Figure 1 and Figure 2 Some containers need to be able to transport overweight cargo, and conventional slot structures cannot meet the load-bearing requirements. Therefore, a matching design is made to the structure, and the slot is reinforced. The reinforcement of the slot opening is usually achieved by welding three thick plates with beveled edges together as a single piece, such as... Figure 3 If it were made into a single structure, the cost would be higher due to the amount of scrap material.

[0003] For example, patent document CN212922874U discloses a container frame and a container, which includes a bottom side beam and a reinforcing plate. Two slots are opened on the web of the bottom side beam, and the reinforcing plate is located above the slots. A column is set on each side of the slot along the width direction. The two columns and a reinforcing plate are welded around the slots to reinforce the area around the slots of the bottom side beam.

[0004] Therefore, it can be seen that the existing technology uses multiple plates to be spliced ​​together for welding reinforcement. The spliced ​​structure has two disadvantages: one is that the work efficiency of splicing and welding into a whole is low; the other is that the strength of the spliced ​​structure is not as high as that of the whole structure. Therefore, the strength requirements can only be met by increasing the thickness of the spliced ​​plates, which also increases the material cost. Utility Model Content

[0005] The purpose of this utility model is to provide a slot reinforcement structure for an ultra-heavy box, aiming to solve the technical problems of low construction efficiency and lack of overall strength improvement in existing structures. The specific technical solution is as follows: A slot reinforcement structure for an overweight container includes a reinforcing plate body disposed on the lower side beam of the container. The lower side beam has slots for forklift insertion. The reinforcing plate body is fixedly connected to the outer side surface of the lower side beam. The reinforcing plate body includes a main plate and two side plates, which are respectively arranged at both ends of the main plate and extend downward. The main plate and the two side plates are a single piece of plate, which is integrally cut and formed. An clearance groove is formed between the two side plates, and the width A of the clearance groove is greater than or equal to the width B of the main plate. The clearance groove is aligned with the slot so that the main plate and the two side plates are arranged around the left, upper and right sides of the slot.

[0006] Furthermore, the height D of the motherboard extending upward is less than or equal to the depth E of the clearance groove, so that the material cut from the clearance groove of the previous motherboard just forms the top part of the next motherboard.

[0007] Preferably, the groove opening of the clearance groove is chamfered, and the small triangular plate missing at the chamfer is arranged at the connection between the main plate and the side plate, and the small triangular plate is arranged on the side away from the clearance groove. The two small triangular plates, the main plate and the two side plates are a whole plate, which is formed by integral cutting.

[0008] Preferably, the main board is arranged in a rectangle, and the two side plates are also arranged in a rectangle, with the sides of the side plates connected to the ends of the main board.

[0009] Preferably, the main board is arranged in a rectangular shape, and the two side plates are arranged in parallelograms. The side surfaces of the side plates are arranged in contact with the end faces of the main board, and the top surfaces of the side plates are arranged as downward sloping surfaces.

[0010] Furthermore, the acute angle end of the side plate away from the main board is arranged with a chamfered corner, and the reinforcing triangular plate with the chamfered corner removed is welded and fixedly connected to the inner side of the side plate.

[0011] Preferably, the thickness of the reinforcing plate body is greater than or equal to 4 mm and less than or equal to 12 mm.

[0012] Preferably, the thickness of the reinforcing plate body is 10 mm.

[0013] The application of the technical solution of this utility model has the following beneficial effects: Through the above structural design, the main body of the reinforcing plate can be made from a large plate by cutting and shaping it. After cutting, the excess material can be minimized, avoiding material waste. In addition, the main body of the reinforcing plate formed by cutting is a whole, which does not require assembly and welding. This improves the overall strength of the reinforcing plate while reducing labor intensity and greatly improving economic efficiency.

[0017] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be provided below, along with preferred embodiments. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this utility model.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0019] Example 1: See Figures 4-6 This embodiment provides a slot reinforcement structure for an overweight container, including a reinforcing plate body disposed on the lower side beam 8 of the container. The lower side beam 8 has slots 9 for forklift insertion. The reinforcing plate body is welded and fixedly connected to the outer side surface of the lower side beam 8. The reinforcing plate body includes a main plate 1 and two side plates 2, which are respectively arranged at both ends of the main plate 1 and extend downwards. The main plate 1 and the two side plates 2 are a single piece, integrally cut and formed. Specifically, the main plate 1 and the two side plates 2 are integrally machined, i.e., the main plate 1 and the two side plates 2 are... No welding is required between the two side plates 2. A clearance groove 3 is formed between them. The width A of the clearance groove 3 is slightly larger than the width B of the main plate 1 (because the cutting seam will occupy a certain width during cutting). The part of the main plate 1 that protrudes upward from the side plate 2 is formed by the material inside the cut clearance groove 3. The clearance groove 3 is aligned with the slot 9 so that the main plate 1 and the two side plates 2 are welded and fixed around the left, upper and right sides of the slot 9, thereby strengthening the periphery of the slot 9, improving the strength around the slot 9, and preventing the slot 9 from deforming or tearing and failing during container insertion.

[0020] It is understood that, through the above structural design, the main body of the reinforcing plate can be made from a large sheet of material through cutting, and the cutting process can minimize excess material 10, thus avoiding material waste. Furthermore, the main plate 1 and the two side plates 2 in the cut reinforcing plate are a single unit, requiring no assembly or welding, which improves overall strength while reducing labor intensity and significantly increasing economic efficiency.

[0021] It should be noted that in this embodiment, the main board 1 and the two side plates 2 of the reinforcing plate body are integrally produced by punching. In some other embodiments of this application, the main board 1 and the two side plates 2 can also be produced by any one of laser cutting, plasma cutting, or flame cutting. Because the reinforcing plate body produced by punching is sheared between adjacent reinforcing plate bodies during punching, there is no material loss; therefore, the groove width A is approximately equal to the width B of the main board 1.

[0022] Furthermore, the height D of the motherboard 1 extending upward is less than or equal to the depth E of the clearance groove 3, so that the material cut from the clearance groove 3 on the previous motherboard 1 just forms the top part of the next motherboard 1.

[0023] It can be seen that, through the design of the above structure, the material cut from the clearance groove 3 in one of the reinforcing plates forms the part of the main plate 1 protruding upward relative to the side plate 2 in the adjacent reinforcing plate. By adjusting the dimensions of each reinforcing plate, the amount of excess material 10 is reduced, thus reducing material waste. That is to say, excess material 10 will only appear at the top of the first reinforcing plate and the bottom of the last reinforcing plate. Since the size of the excess material 10 is small in actual operation, the excess material 10 will become waste.

[0024] The motherboard 1 is arranged in a rectangle, and the two side panels 2 are also arranged in a rectangle. The sides of the side panels 2 are connected to the ends of the motherboard 1. The motherboard 1 and the two side panels 2 are cut from a large piece of material, and the motherboard 1 and the two side panels 2 are cut into a whole.

[0025] Preferably, the thickness of the reinforcing plate body is greater than or equal to 4 mm and less than or equal to 12 mm. 8 mm and 10 mm are commonly used. This provides good reinforcement and is relatively easy to process. Of course, the reinforcing plate can also be made of other thicknesses between 4 mm and 12 mm.

[0026] Example 2: Reference Figures 7-9 The difference between this embodiment and Embodiment 1 is that the groove opening of the clearance groove 3 is provided with a chamfer 4, and the small triangular plate 5 missing at the chamfer 4 is arranged at the connection between the main board 1 and the side plate 2. The small triangular plate 5 is arranged on the upper side away from the clearance groove 3. The two small triangular plates 5, the main board 1 and the two side plates 2 are a whole plate, which is integrally processed.

[0027] It should be noted that, after research, it was found that, regarding the improvement of Embodiment 1, the connection between the main board 1 and the side plate 2 is a right-angle transition, which is prone to stress concentration at the right-angle transition and the connection is relatively weak.

[0028] Through the above structural design, when the plate is processed and cut, a chamfer 4 is processed and set at the groove opening of the clearance groove 3, and the small triangular plate 5 of the chamfer 4 forms a reinforcing part of the adjacent body. That is, the connection between the main plate 1 and the side plate 2 of the adjacent reinforcing plate body is reinforced by the small triangular plate 5. Without increasing the excess material 10 and labor intensity, the rigidity of the reinforcing plate body is further enhanced.

[0029] The remaining aspects are basically the same as in Example 1, and will not be repeated here.

[0030] Example 3: Reference Figure 10 and Figure 13 The difference between this embodiment and Embodiment 1 is that the main board 1 is arranged in a rectangle, the two side plates 2 are both arranged in parallelograms, the side surfaces of the side plates 2 are arranged in contact with the end surfaces of the main board 1, and the top surface of the side plates 2 is arranged as a downward sloping surface.

[0031] It is known that by setting the upper part of the joint between the motherboard 1 and the side plate 2 as an obtuse angle, stress concentration is relieved, the probability of damage is reduced, and the connection area between the motherboard 1 and the side plate 2 is increased, thereby improving the connection rigidity between the motherboard 1 and the side plate 2.

[0032] When the acute angle end of the side plate 2 away from the main plate 1 is cut, it is chamfered 6. The reinforcing triangular plate 7 removed by chamfering 6 is then fixedly connected to the inclined surface on the inner side of the side plate 2 by welding to fill the missing part on the inner side of the side plate 2.

[0033] The above design increases the area of ​​the lower end of side plate 2, improves the rigidity of the lower end of side plate 2, and reduces material waste.

[0034] The remaining aspects are basically the same as in Example 1, and will not be repeated here.

[0035] Example 4: Reference Figures 14-16 The difference between this embodiment and Embodiment 2 is that a reinforcing triangular plate 7 can be divided at the upper end of the side plate 2 away from the main board 1. The divided reinforcing triangular plate 7 can be used to compensate the position of the lower inner side of the side plate 2 to form a complete reinforcing body, and is welded to the outer periphery of the slot of the lower side beam.

[0036] The remaining aspects are basically the same as in Example 2, and will not be repeated here.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
