The invention provides a straddle type monorail synchronous beam-changing turnout. The straddle type monorail synchronous beam-changing turnout comprises a straight beam, a curved beam, a trolley, a fixed end stacked beam, a movable end stacked beam, a driving device and a hinge shaft device. The fixed end stacking beam, the movable end stacking beam and the driving device are all installed on a turnout foundation. The two fixed end stacked beams are respectively connected with the first ends of the straight beam and the curved beam; a plurality of trolleys with rollers are arranged at the bottoms of the straight beams and the curved beams; one end of the hinge shaft device is installed on the turnout foundation, and the other end is connected with the straight beam or the curved beam. According to the track switch, the double-swing guide rod mechanism replaces an electric push rod to serve as a driving device and is arranged at the rear section of the track switch beam, so that the track switch precision of the track switch can be effectively improved, and the track switch debugging difficulty can be effectively reduced; The extra load on the driving device caused by straight beamdeformation due to environment temperature change can be effectively reduced; one drive drives two turnout beams at the same time, no hinge connecting rod is arranged between the two beams, and the overall safety and stability of the turnout are improved.

    本发明提供了一种跨座式单轨同步换梁型道岔,包括直梁、曲梁、台车、固定端垛梁、活动端垛梁、驱动装置和铰轴装置;固定端垛梁、活动端垛梁和驱动装置均安装在道岔基础上;两个固定端垛梁分别与直梁、曲梁的第一端连接;直梁和曲梁底部设置多部带滚轮的台车;铰轴装置一端安装在道岔基础上,另一端与直梁或曲梁连接。本发明中,用双摆动导杆机构代替电动推杆作为驱动装置,且布置在道岔梁的后段,能有效提高道岔的转辙精度和降低道岔调试难度,因为摆臂滚轮与导槽之间有一定间隙,能有效降低因环境温度变化带来的直梁变形所产生的对驱动装置的额外负荷;一个驱动同时驱动两条道岔梁,两条梁之间没有铰接连杆,提高了道岔的整体安全性和稳定性。
