Description

Technical Field

[0001] This utility model relates to the field of container manufacturing and processing, and in particular to a welding device for container side panels. Background Technology

[0002] Containers are a commonly used mode of transportation in the industry, widely applied in international multimodal transport and in critical power support applications such as containerized power plants in data centers. Because containers need to facilitate the loading and unloading of goods by machinery, they are typically large, which increases the difficulty of container assembly.

[0003] Currently, many manufacturers have implemented automated production lines for container processing. Since automated production lines start with the assembly and welding of the container body, the welding of the side panels is completed on a welding platform. Because the corrugated plates and profiles of the side panels are generally not on the same plane, and the corrugated plates are easy to deform and difficult to weld; during robot welding, the corrugated plates are easily heated and become parallelograms, resulting in large dimensional errors; moreover, when the welded side panels are transferred, the lack of limiters on the upper and lower sides of the corrugated plates can easily cause deformation of the side panels, affecting the overall quality of the container.

[0004] The patent application number "CN201620851241.1" discloses a "non-standard container top and bottom welding fixture". Although it can be adapted to containers of different sizes, it is mainly for welding the top and bottom surfaces of containers and cannot be used for welding the side panels of containers. Summary of the Invention

[0005] The purpose of this invention is to provide a welding device for container side panels, which can improve the welding quality of container side panels and facilitate the assembly of the side panels with the container as a whole.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A welding device for container side panels includes a rectangular frame, which is composed of two uprights and two auxiliary supports that are spot-welded together. A door frame assembly is provided inside the rectangular frame. The door frame assembly includes a first door frame vertical support and a second door frame vertical support arranged parallel to the uprights. The two ends of the two door frame vertical supports are spot-welded to the two auxiliary supports respectively. A door frame horizontal support is also provided between the two door frame vertical supports. An access passage is formed between the door frame horizontal support, the two door frame vertical supports and the auxiliary support.

[0007] Preferably, the rectangular frame is further provided with a bottom support member for supporting the corrugated sheet.

[0008] Preferably, the bottom support member includes: The first bottom support is located between the first door frame vertical brace and a column; The third bottom support is located between the second door frame vertical brace and another column; The second bottom support is located between the first and second door frame vertical supports.

[0009] Preferably, the first bottom support and the third bottom support are each provided in three parallel locations, and the second bottom support is provided in two parallel locations.

[0010] Preferably, the first bottom support, the second bottom support, and the third bottom support are all formed by bending steel plates.

[0011] Preferably, the auxiliary support is provided with lifting lugs for easy hoisting.

[0012] Preferably, the entrance / exit passage is provided with four door frame folds around its perimeter, and the four door frame folds are connected to the door frame horizontal brace, two door frame vertical braces, and one auxiliary brace.

[0013] The beneficial effects of this utility model are as follows: 1. By setting up auxiliary supports, the upper and lower sides of the corrugated plate can be limited during the hoisting and transportation of the welded side plates to prevent deformation and improve the assembly quality of the finished container.

[0014] 2. When welding corrugated sheets, bottom supports are used to ensure that the corrugated sheets, columns, and door frame components are on the same plane, which can effectively reduce the deformation of the corrugated sheets and improve the welding quality.

[0015] 3. The bottom support only serves to support the corrugated sheet and is not connected to the columns, door frame components, auxiliary supports, etc. When hoisting the container side panels after welding, it can be directly removed.

[0016] 4. The auxiliary supports are spot-welded to the columns and door frame components. After the container side panels are welded and hoisted into place and connected to the container as a whole, the auxiliary supports can be removed by grinding or other means for reuse.

It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0019] The present invention will now be further described with reference to the accompanying drawings. Example

[0020] like Figure 1 — Figure 9 As shown, this embodiment of a welding device for container side panels includes a rectangular frame. The rectangular frame is composed of two uprights 1 and two auxiliary supports 4, which are spot-welded together. A door frame assembly 3 is also provided within the rectangular frame. The door frame assembly 3 includes a first door frame vertical support 31 and a second door frame vertical support 32 arranged parallel to the uprights 1. Both ends of the two door frame vertical supports are spot-welded to the two auxiliary supports 4 respectively. This allows the auxiliary supports 4 to be removed and reused after welding is completed and the container side panel is hoisted to the container assembly position. A door frame horizontal support 33 is also provided between the two door frame vertical supports. The door frame horizontal support 33, the two door frame vertical supports, and the auxiliary support 4 form an access passage for the entry and exit of operators or materials.

[0021] like Figure 5 As shown, a bottom support component for supporting the corrugated sheet is also provided inside the rectangular frame.

[0022] The bottom support components include: The first bottom support 51 is located between the first door frame vertical brace 31 and a column 1; The third bottom support 53 is located between the second door frame vertical support 32 and another column 1; The second bottom support 52 is located between the first door frame vertical support 31 and the second door frame vertical support 32.

[0023] The first bottom support 51 and the third bottom support 53 are each arranged in three parallel locations, and the second bottom support 52 is arranged in two parallel locations. The first bottom support 51, the second bottom support 52 and the third bottom support 53 are not connected to the column 1, the auxiliary support 4 and the door frame assembly 3, but are only placed under the corrugated plate 2 to support it, thereby improving the welding quality between the corrugated plate 2 and the column 1 and the door frame assembly 3.

[0024] like Figure 6 As shown, the first bottom support 51, the second bottom support 52 and the third bottom support 53 are all formed by bending steel plates, and their height dimensions are determined according to the height difference between the bottom surface of the corrugated plate and the column 1.

[0025] like Figure 2 As shown, the auxiliary support 4 is equipped with lifting lugs 41 for easy hoisting, which facilitates hoisting after welding.

[0026] like Figure 4 As shown, four door frame folds 34 are provided around the entrance and exit passage. The four door frame folds 34 are connected to the door frame horizontal brace 33, two door frame vertical braces and one auxiliary brace 4.

[0027] like Figure 1 As shown, during the use of this device, two uprights 1 and two auxiliary supports 4 are first spot-welded to form a rectangular frame, ensuring that the upper surfaces of the uprights 1 and auxiliary supports 4 are flush to guarantee the design dimensions. Then, the door frame assembly 3 is spot-welded to the rectangular frame (including the two auxiliary supports 4). During this process, it is necessary to ensure that the upper surfaces of the first door frame vertical support 31, the second door frame vertical support 32, and the door frame horizontal support 33 are flush to guarantee the design dimensions. After welding, the auxiliary supports 4 ensure the external dimensions of the rectangular frame and guarantee the flatness of the frame. The welded structure is as follows. Figure 3 As shown. Then, four door frame folds 34 are welded around the entrance / exit passage. The welded structure is as follows. Figure 4 As shown. Then, the first bottom support 51, the second bottom support 52, and the third bottom support 53 are placed with their planes facing upwards within the rectangular frame, as shown in the diagram. Figure 5 As shown. Then, corrugated sheet 2 is placed into the rectangular frame and spot-welded to the frame. The welded structure is as follows. Figure 7 As shown. In this embodiment, because the container side panels are large and the corrugated sheet 2 is long, it is divided into four first corrugated sheets 21, one second corrugated sheet 22, and one third corrugated sheet 23. The access passage is opened on the second corrugated sheet 22, as shown. Figure 8 As shown. The specific structure of the corrugated board is as follows. Figure 9 As shown.

[0028] After the aforementioned welding is completed, a crane is used to lift it to the robotic welding platform for welding. Then, it is lifted to the assembly area, where the two auxiliary supports 4 are removed. The auxiliary supports 4 are reusable. The finally welded container side panel is as follows: Figure 8 As shown.
