A high-speed turnout assembly platform is provided, which is composed of a horizontal height adjusting system, a cross beam, a fixed base plate and a fastening system. The horizontal height adjusting system is used to adjust the height and horizontal position of the cross beam. The bottom of the cross beam is connected to the top of the horizontal height adjusting system. The fixed base plate is fixedly installed on the horizontal surface of the cross beam. The fixed base plate is used to set the high-speed turnout. The fastening system is arranged outside the fixed base plate and is used to stabilize and compress the high-speed turnout. The utility model realizes stable compression and fastening of the turnout, and the fastening system is simple and convenient to disassemble. The height and horizontal position of the cross beam can be adjusted, and the turnout assembly efficiency is improved. The modular design is easy to check and maintain, can be reused, and can reduce the cost.
