摘　　要：有轨电车项目的转辙机通常会考虑地埋式的安装环境,现有的国内转辙机绝大多数为电动驱动,并且动程不可调。详细介绍一种有轨电车专用地埋式电液转辙机的结构特点和动作原理。该转辙机具有体积小、结构紧凑、动程可调、安装调试方便、稳定性好、可靠性高等优点。Switch machines for tram projects usually consider buried installation environments. The existing domestic switch machine is usually electric-driven and the stroke is not adjustable. This paper introduces in detail the structural characteristics and operating principle of a buried electro-hydraulic switch machine specially designed for trams. The switch machine has the advantages of small size, compact structure, adjustable stroke, convenient installation and debugging, good stability and high reliability.
