Cemented plateau railway seamless turnout and seamless method
The invention provides a cemented plateau railway seamless turnout, which comprises a straight stock rail, a curved stock rail, a straight switch rail, a curved switch rail, a guard rail, a fixed frog and a contact group, 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, and the curved stock rail and the curved switch rail have the same trend direction. The fixed frog is arranged at the intersection position of the curved point rail line type, the straight stock rail line type and the frog, the fixed frog is connected with the tail end of the curved point rail and the tail end of the straight point rail, the guard rail is arranged on the inner side of the working edge of the straight stock rail and the inner side of the working edge of the curved point rail, and the contact group is arranged on the rail and is a seamless contact; the contact groups on the straight switch rail, the curved switch rail and the fixed frog are freezing joints or welding joints, and the contact groups on the straight stock rail and the curved stock rail are all welding joints. According to the method, the structural characteristics of the turnout are fully considered, targeted measures are taken according to plateau climate conditions, and the defect that only the plain area is considered in a traditional technical scheme is overcome.
本发明提供了一种胶结高原铁路无缝道岔，包括直基本轨、曲基本轨、直尖轨、曲尖轨、护轨、固定型辙叉和接点组，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，曲基本轨和曲尖轨走势方向相同，曲尖轨线型与直基本轨线型、辙叉交叉位置设置固定型辙叉，固定型辙叉连接曲尖轨末端和直尖轨末端，护轨设置于直基本轨工作边内侧和曲基本轨工作边内侧，接点组设置于铁轨上，接点组为无缝接点；直尖轨、曲尖轨和固定型辙叉上的接点组为冻结接头或焊接接头，直基本轨和曲基本轨上的接点组均为焊接接头。本发明充分考虑了道岔的结构特点，并针对高原气候条件做了针对性的措施，突破了传统技术方案仅考虑平原地区的特点。
