Plateau railway seamless turnout with optimized structure
The invention provides a plateau railway seamless turnout with an optimized structure, which comprises a straight stock rail, a curved stock rail, a straight switch rail, a curved switch rail, a first guard rail, a second guard rail, a fixed frog, a welding joint group and a cementing insulation joint group, the straight stock rail and the straight switch rail are arranged in parallel, and the curved stock rail is arranged on the outer side of the straight switch rail; the curved switch rail is arranged between the straight stock rail and the straight switch rail, the line type of the curved switch rail is crossed with the line type of the straight stock rail and the line type of the straight switch rail, the fixed frog is arranged at the crossed position and connected with the tail ends of the curved switch rail and the straight switch rail, and the guard rail is arranged on the inner sides of working edges of the straight stock rail and the curved stock rail. The cementing insulation joint group is arranged at a steel rail connection position between the curved stock rail and the curved switch rail; welding joint groups are arranged at other steel rail connecting positions. By optimizing the turnout structure, the welding error-tolerant rate of the plateau railway turnout can be increased, the adaptability is high, and the welding flux optimization, the process optimization and the like can be combined to further increase the welding joint error-tolerant rate of the plateau railway turnout area.
本发明提供了一种结构优化的高原铁路无缝道岔，包括直基本轨、曲基本轨、直尖轨、曲尖轨、第一护轨、第二护轨、固定型辙叉、焊接接头组和胶接绝缘接头组，直基本轨和直尖轨平行设置，曲基本轨设置于直尖轨外侧，曲尖轨设置于直基本轨和直尖轨之间，曲尖轨线型与直基本轨线型、直尖轨线型交叉，交叉位置设置固定型辙叉，固定型辙叉连接曲尖轨、直尖轨末端，护轨设置于直基本轨和曲基本轨工作边内侧，胶接绝缘接头组设置在曲基本轨和曲尖轨中部的钢轨连接位置；其余钢轨连接位置设置焊接接头组。本发明通过优化道岔结构可提升高原铁路道岔的焊接容错率，适应性强，可结合焊剂优化、工艺优化等进一步提升高原铁路道岔区焊接接头容错率。
