Description

Technical Field

[0001] This utility model relates to the field of container manufacturing technology, and more specifically, to a container front frame structure. Background Technology

[0002] Currently, refrigerated transport units are widely used and come in many varieties. They are used in conjunction with containers for the cold chain transportation of specific goods. Since refrigeration units need to be installed inside the container, it is necessary to add refrigeration unit panels or other structural elements to the container to facilitate installation. However, existing methods generally involve... Figure 5-7 As shown, carbon steel refrigeration unit tubes are pre-welded to the corner posts, and then refrigeration unit plates are installed on the end faces of the corner posts. T-bolts are inserted through the refrigeration unit tubes to fix the plates to the ends of the corner posts. However, this method has drawbacks: customers often cannot determine which refrigeration unit to use before customizing containers, which makes it impossible to determine which front frame structure to use. The refrigeration unit tubes need to be welded to support the refrigeration unit after the refrigeration unit model and installation location are determined. The production timeline is fixed, ultimately preventing container manufacturers from delivering containers to customers quickly. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a container front frame structure to solve one or more of the above-mentioned problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A container front frame structure includes a main structure welded from corner pieces, a top beam, corner posts, a middle beam, a front wall, and a bottom beam. Angle iron assemblies are welded to the inner surfaces of the corner posts, the top beam, and the middle beam. The angle iron assemblies of the corner posts are welded to the angle iron assemblies of the top beam and the middle beam, respectively.

[0006] Furthermore, the angle iron assembly includes a first angle iron and a second angle iron, both of which are L-shaped structures, and the first angle iron and the second angle iron are stacked and welded together.

[0007] Furthermore, the second angle iron on the corner post is positioned on the outer side, and the first angle iron on the corner post is positioned on the inner side, with the first angle irons of the two corner posts facing each other.

[0008] Furthermore, the second angle iron on the top beam is positioned near the top, and the first angle iron on the top beam is positioned near the middle beam.

[0009] Furthermore, the second angle iron on the intermediate beam is positioned close to the bottom beam, and the first angle iron on the intermediate beam is positioned close to the top beam.

[0010] Furthermore, the first angle iron on the top beam and the first angle iron on the middle beam are respectively welded to the first angle iron on the corner posts on both sides.

[0011] In summary, this utility model has the following beneficial effects: Through structural improvement, the original cold unit round tube, which required welding only after determining the cold unit model and installation location, is replaced with a general-purpose angle iron assembly that can be welded directly. After the cold unit model and installation location are determined, the mounting hole is drilled, which can be applied to the installation of most cold unit models, thus shortening the delivery cycle; the strength of the front frame is improved by welding the angle iron assemblies of the top beam, corner columns, and intermediate beam, preventing easy deformation.

[0020] Example:

[0021] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0022] A container front frame structure, such as Figure 1As shown, this design primarily targets containers with refrigeration units located in the front frame area. The main body of the front frame structure consists of corner pieces 1, top beam 2, two sets of corner posts 3, intermediate beam 4, front wall 5, and bottom beam 6, which are sequentially welded to form the container's body structure. Angle iron assemblies are welded onto the inner surfaces of the top beam 2, intermediate beam 4, and the corner posts 3 on both sides. Each angle iron assembly contains two L-shaped angle iron pieces. The corresponding angle iron pieces of the intermediate beam 4 and top beam 2 are also partially welded to the angle iron pieces of the corner posts 3 on both sides at overlapping portions to enhance the overall strength of the front frame structure.

[0023] Angle iron components generally include an inner first angle iron 7 and an outer second angle iron 8. The second angle iron 8 and the first angle iron 7 are stacked and welded together to form a U-shaped steel structure. This, along with corresponding main components such as the inner surfaces of the middle beam 4, top beam 2, and corner columns 3, forms a closed ring structure. The angle iron components on the two corner columns 3 are positioned opposite each other, as are the angle iron components on the top beam 2 and the middle beam 4. That is, the first angle iron 7 and the second angle iron 8 are positioned opposite each other, forming an enclosing frame structure with the corresponding main components. Typically, the second angle iron 8 is stacked around the first angle iron 7. Specifically, the first angle iron 7 on the left corner column 3 is positioned on the right side, and the second angle iron 8 is positioned on the left side; for example... Figure 2 As shown, the first angle iron 7 on the right corner post 3 is located on the left side, and the second angle iron 8 is located on the right side; as Figure 3 As shown, the first angle iron 7 on the top beam 2 is located on the bottom side, and the second angle iron 8 is located on the top side; as Figure 4 As shown, the first angle iron 7 on the middle beam 4 is located on the top side, and the second angle iron 8 is located on the bottom side; the first angle iron 7 on the top beam 2, the middle beam 4, and the two side corner columns 3 are connected and welded together to form a complete front frame structure.

[0024] The opening dimensions of mainstream refrigeration units are relatively uniform; the main difference lies in the positioning dimensions and parameters of the refrigeration unit's circular tube 9. Replacing the circular tube 9 with angle iron components allows for a wider range of size selection, accommodating more refrigeration unit models. Welding angle iron around the front frame further enhances structural strength, preventing easy deformation after refrigeration unit installation. The front frame structure is positioned according to the specific model parameters and customer requirements, drilling through-holes for refrigeration unit installation. Even if the model is changed temporarily, it can be coordinated by drilling additional mounting holes, avoiding rework or scrap. This type of container design allows for advance production and storage, provided production capacity is sufficient, without affecting production schedules.

[0025] It should be noted that this specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
