[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3 This utility model provides an embodiment of a high-speed rail contact network H-shaped double-section steel column, including a base 1. An installation groove 2 is provided in the upper middle part of the base 1. A first H-shaped steel column 3 is slidably connected to the left side of the installation groove 2, and a second H-shaped steel column 4 is slidably connected to the right side of the installation groove 2. Limiting grooves 5 are provided on both the front and rear sides of the upper part of the base 1. Limiting blocks 7 are slidably connected to the bottom of the limiting grooves 5. Connecting blocks 6 are fixedly connected to the upper part of the limiting blocks 7. An assembly component is provided on the upper part of the connecting blocks 6 for assembling the H-shaped steel columns. The assembly component includes an installation plate 8, which is fixedly connected to the upper part of the connecting blocks 6. Connecting plates 9 are fixedly connected to the left and right sides of the opposite side of the installation plate 8. Bolts 10 are evenly inserted inside the connecting plates 9. The limiting blocks 7 are slidably connected to the outside of the first H-shaped steel column 3 and the second H-shaped steel column 4. The first H-shaped steel column 3 and the second H-shaped steel column 4 are both fixedly connected to the connecting plates 9 by bolts 10. The connecting blocks 6 are slidably connected inside the limiting grooves 5. The bolts 10 are made of stainless steel.

[0027] When assembling the H-shaped steel columns, first push the first H-shaped steel column 3 to move it to the left side inside the mounting groove 2, then push the second H-shaped steel column 4 to move it to the right side inside the mounting groove 2. Next, push the mounting plate 8, which in turn drives the connecting plate 9 to move accordingly, ensuring that the connecting plate 9 can slide to the side where the first H-shaped steel column 3 and the second H-shaped steel column 4 are far apart. Finally, by rotating the bolt 10, the connecting plate 9 is connected and fixed to the first H-shaped steel column 3 and the second H-shaped steel column 4. This achieves simple and quick assembly of the H-shaped double-section steel columns of the high-speed rail contact network, greatly improving assembly efficiency and reducing the complexity and error of manual operation. It ensures the high efficiency and accuracy of the assembly process, enabling more assembly tasks to be completed in a limited time.

[0028] Reference Figures 1-3 The base 1 is made of carbon steel, the first H-shaped steel column 3 and the second H-shaped steel column 4 are both made of stainless steel, the connecting block 6 and the limiting block 7 are both made of cast iron, the mounting plate 8 is made of aluminum alloy, and the connecting plate 9 is made of stainless steel.

[0029] By using carbon steel to ensure the compressive strength, stability, and corrosion resistance of the base 1, it can withstand high-intensity loads and corrosion in various harsh environments. By using stainless steel to improve the strength and corrosion resistance of the first H-shaped steel column 3 and the second H-shaped steel column 4, it can cope with various external pressures and climate changes that may be encountered in high-speed rail lines. By using cast iron to improve the stability and wear resistance of the connecting block 6 and the limiting block 7, it effectively reduces structural changes caused by wear. By using aluminum alloy to ensure the lightweight and corrosion resistance of the mounting plate 8, and by using stainless steel to ensure the corrosion resistance of the connecting plate 9, the overall performance of the H-shaped double-section steel column is improved, its service life is extended, the frequency of maintenance and replacement of parts is reduced, and the long-term reliable operation of the high-speed rail contact network system is ensured.

[0030] Working principle: When it is necessary to assemble the H-shaped steel columns, push the first H-shaped steel column 3 to move it to the left side inside the mounting groove 2, push the second H-shaped steel column 4 to move it to the right side inside the mounting groove 2, and then push the mounting plate 8 to move the connecting plate 9 so that the connecting plate 9 slides to the side where the first H-shaped steel column 3 and the second H-shaped steel column 4 are far apart. Finally, rotate the bolt 10 to connect the connecting plate 9 with the first H-shaped steel column 3 and the second H-shaped steel column 4. This makes it easier to assemble the double-section H-shaped steel columns of the high-speed rail contact network and improves its assembly efficiency.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
