The invention belongs to the railway turnout technology, and particularly relates to a pneumatic turnout for a metallurgical railway, which comprises a stock rail, a switch rail assembly, a pneumatic switch machine and a purging device, the switch rail assembly consists of a switch rail, a middle connecting rod, a joint, a pull rod and a buffer spring, the middle connecting rod is connected with the switch rail, the joint is positioned in the center below the middle connecting rod, and the pull rod penetrates through the joint and is connected with the pneumatic switch machine. The pull rod drives the switch rail to move through the connector, the proximity switches are installed on the pull rod, the proximity switches are arranged on the two sides of the connecting position of the switch rail and the pull rod, and starting and standby of the purging system are controlled by sensing whether the spring is excessively compressed or not.
本发明属于铁路道岔技术,具体是指一种冶金铁路用气动道岔,包括基本轨、尖轨组件、气动转辙机和吹扫装置,其中尖轨组件由尖轨、中间连杆、接头、拉杆和缓冲弹簧组成,中间连杆连接尖轨,接头位于中间连杆下方的正中央处,拉杆穿过接头,拉杆通过接头带动尖轨移动,通过在拉杆上安装接近开关,在尖轨与拉杆的连接处的两侧设置接近开关,通过感应弹簧是否过量压缩来控制吹扫系统的启动和待机。
