[0002] In the railcar such as subway and high speed rail, high voltage equipment such as high voltage transformer and control cabinet and matched high pressure box are generally equipped. The high pressure box is installed in the car body of the railcar to facilitate the installation of high voltage equipment such as high voltage transformer and control cabinet inside the high pressure box. Generally, the high pressure box is partially embedded on the car body, and the other part is used to connect the high pressure box. Therefore, the high pressure box generally uses a unified standard structure.

[0003] The high pressure box in the prior art generally adopts split section bars, that is, upper flange section bar, middle flange section bar (also called apron section bar) and angle aluminum section bar (lower frame), which are welded together to form a frame. The outer edge of the frame is riveted or welded with a skin, and structure glue is applied around the skin. The split section bars are processed into high pressure boxes, which not only have large workloads, time-consuming and laborious, and high experience requirements for construction workers, but also increase the scrap rate of high pressure boxes and reduce production efficiency. At the same time, it is easy to cause incomplete welding and incomplete glue, which causes water to enter the high pressure box and leads to accidents.

[0004] It is necessary to design an integrated section bar structure for facilitating the production and processing of high pressure boxes. CONTENT OF THE UTILITY MODEL

[0005] In order to solve the above problems existing in the prior art, the utility model provides a section bar structure for high pressure box production.

[0006] The utility model adopts the technical scheme that:

The part above the side stopper is an upper extension frame, and the part below the side stopper is a lower extension frame.

[0008] The section bar structure comprises an upper plate part, a side horizontal plate and a lower plate part. The upper plate part, the side horizontal plate and the lower plate part are connected with each other and form a T-shaped structure. The upper plate part and the lower plate part are located on the same plane, and the side horizontal plate is perpendicular to the upper plate part and the lower plate part. The side horizontal plate is used for forming the side stopper, the upper plate part is used for forming the upper extension frame, and the lower plate part is used for forming the lower extension frame.

[0009] As an alternative or supplement to the above scheme, a groove type part is arranged at the upper edge of the upper plate part, and the groove direction of the groove type part is perpendicular to the upper plate part. After the section bar structure is made into a high pressure box, the slot of the groove type part faces the outer side of the high pressure box.

[0010] As an alternative or supplement to the above scheme, a square tube section is provided at the upper edge of the upper plate section, and the upper surface of the square tube section is flush with the upper surface of the channel section; after the profile structure is made into a high-pressure box, the square tube section is located inside the channel section.

[0011] As an alternative or supplement to the above solution, the upper surface of the square tube section is provided with an upper protruding ridge, and an L-shaped notch is formed between the upper protruding ridge and the upper surface of the square tube section; after the profile structure is made into a high-pressure box, the L-shaped notch is used to install the sealing ring.

[0024] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0025] like Figures 1 to 4 As shown in the figure, this embodiment designs a profile structure for the production of high-pressure boxes.

[0026] The high-voltage box is square in shape, such as Figure 3 As shown, an outwardly extending side guard 2 is provided at the middle of the outer side of the high-voltage box. After installation, the side guard 2 abuts against the floor or ceiling of the rail vehicle car, thereby limiting its movement and reducing the probability of the high-voltage box settling. The part above the side guard 2 is the upper extension frame 1, and the part below the side guard 2 is the lower extension frame 3. When the high-voltage box is installed in the car, the lower extension frame 3 is embedded and connected to the side wall of the car; the upper extension frame 1 extends out of the side wall of the car and is used to connect and fix the high-voltage box.

[0027] The profile structure in this design includes the upper plate 4, the side cross plates 5, and the lower plate 6.

[0028] The upper plate 4, the side cross plate 5, and the lower plate 6 are interconnected to form a T-shaped structure. The upper plate 4 and the lower plate 6 are located on the same plane, and the side cross plate 5 is perpendicular to the upper plate 4 and the lower plate 6. The side cross plate 5 is used to form the side edge 2, the upper plate 4 is used to form the upper extension frame 1, and the lower plate 6 is used to form the lower extension frame 3.

[0029] Furthermore, a groove-shaped portion 10 is provided at the upper edge of the upper plate portion 4, and the groove direction of the groove-shaped portion 10 is perpendicular to the upper plate portion 4; after the high-voltage box is made of profile structure, the groove opening of the groove-shaped portion 10 faces the outside of the high-voltage box. The groove of the groove-shaped portion 10 is a T-shaped groove structure, which facilitates the docking of the high-voltage box with external components and provides conditions for fixing accessories during the installation of the high-voltage box.

[0030] A square tube section 9 is provided at the upper edge of the upper plate section 4. The upper surface of the square tube section 9 is flush with the upper surface of the channel section 10 to increase the area of ​​the upper end face of the profile structure, thereby providing more stable support for the high-voltage box after it is connected. After the profile structure is made into a high-voltage box, the square tube section 9 is located inside the channel section 10.

[0031] The upper surface of the square tube section 9 is provided with an upper protruding ridge 11, and an L-shaped notch is formed between the upper protruding ridge 11 and the upper surface of the square tube section 9; after the profile structure is made into a high-pressure box, the L-shaped notch is used to install the sealing ring 12.

[0032] A central reinforcing section 8 is provided at the connection point of the upper plate 4, the side transverse plate 5, and the lower plate 6. The central reinforcing section 8 strengthens the connection point and reduces deformation. The central reinforcing section 8 can be square tubular in shape, such as... Figure 1 As shown. The central reinforcing section 8 is located on the side of the profile structure away from the side cross plate 5.

[0033] The lower plate 6 has a lower folded edge 7 at its lower part, and the lower plate 6 and the lower plate 6 form an L-shaped structure. The lower folded edge 7 not only strengthens the structural strength of the lower plate 6, but also provides a foundation for the installation of accessories of the high-voltage box, thereby improving the structural stability of the high-voltage box.

[0034] In existing technology, the process of using split profiles is as follows: using the upper flange profile ( Figure 5 a) Middle flange profile ( Figure 5 b) Angle aluminum profile ( Figure 5 c), square tubing and existing accessories are cut, welded, and assembled to form a rough frame structure. Figure 6 Then, work such as skinning, riveting, and gluing is carried out to produce... Figure 6 The structure shown in b is as described above. The above process has the following drawbacks: 1. It requires skin panels and support rods for connection, resulting in a complex structure; 2. It involves many parts and a large amount of welding, making it prone to welding defects and difficult to guarantee quality; 3. In addition to the base plate, it requires the riveting of 10 skin panels on the upper and lower layers of the four sides. Adhesive needs to be applied between the skin panels and the frame during riveting, and each rivet requires adhesive, resulting in a large amount of adhesive and making quality control difficult, potentially leading to hidden problems; 4. All connections with the skin panels, both inside and outside, require adhesive, resulting in a large workload and difficulty in guaranteeing quality; 5. The skin panels and rivets are scattered around, creating an uneven appearance; the rivets can easily affect sanding and painting, and paint is prone to dripping.

[0035] Compared with the above-mentioned separate profile manufacturing method, this embodiment uses an integral profile for production and processing, achieving the effect of a combined structure of upper flange profile, middle flange profile, angle aluminum profile, and skin. It has the following advantages: 1. One-time molding, simple and reliable, good structure, and high strength; 2. It can be formed by four profile sections, requiring only welding of four corners and load-bearing supports, resulting in less welding. The weld strength is generally about 90% of the base material strength, and the overall strength is slightly improved due to the reduction in welds; 3. Only the base plate needs to be riveted, ensuring sealing; 4. Only the inner and outer sides of the base frame and the two observation ports need to be sealed, reducing workload; 5. No side panels, and rivets concentrated at the bottom, resulting in a beautiful and integrated appearance; it is also easy to sand and paint, less prone to defects such as drips, and can effectively improve production efficiency.

[0036] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
