Vibration reduction type urban rail turnout switch
The invention relates to a vibration reduction type urban rail frog switch which comprises stock rails, switch rails, a steel rail joint structure and a frog vibration reduction supporting structure, the stock rails comprise a straight stock rail and a curved stock rail, the switch rails comprise a curved switch rail and a straight switch rail, the curved stock rail and the curved switch rail are used for side strand passing, and the rail joint structure comprises a steel rail joint structure and a frog vibration reduction supporting structure. The straight stock rail and the linear switch rail are used for straight strand passing, the straight stock rail and the curved stock rail are connected through the spacer iron, the curved stock rail and the linear switch rail are connected through the spacer iron, the steel rail joint structure is arranged at the connecting position of adjacent steel rails, and the railroad switch vibration reduction supporting structure is arranged below an urban rail line running rail. The rail gauge change rate in the switch rail range is reduced, the operation stability of a train in the turnout range is improved, the vibration influence of the train on surrounding buildings is reduced fundamentally, meanwhile, the vibration reduction type supporting structure is of an upper locking type structure, and meanwhile later maintenance of a public work department is facilitated.
本发明涉及一种减振型城轨道岔转辙器，包括基本轨、尖轨、钢轨接头结构与转辙器减振支撑结构，所述基本轨包括直基本轨和曲基本轨，所述尖轨包括曲线尖轨和直线尖轨，所述曲基本轨与曲线尖轨用于侧股通行，所述直基本轨与直线尖轨用于直股通行，所述直基本轨与曲线尖轨间通过间隔铁连接，所述曲基本轨与直线尖轨通过间隔铁连接，所述钢轨接头结构设置于相邻钢轨连接处，所述转辙器减振支撑结构设置于城轨线路走行轨下方，降低了在尖轨范围的轨距变化率，提高了列车在道岔范围的运行平稳性，进而在根源上降低了列车对周边建筑物的振动影响，同时减振型支撑结构采用上锁式结构，同时方便了后期工务部门的维修。
