The invention relates to the technical field of railway traffic equipment, in particular to a high-integration-level hydraulic assembly for electro-hydraulic switching, which comprises a hydraulic valve block, a connecting plate fixed on the hydraulic valve block, an oil tank fixedly arranged on one side of the connecting plate, a piston rod fixedly arranged on the hydraulic valve block, and a piston rod fixedly arranged on the piston rod. The oil cylinder can be movably arranged on the piston rod, an oil pump and an oil-immersed motor are arranged in the oil tank, and the oil pump is fixedly connected with the oil-immersed motor. An oil-immersed motor is used, the motor and an oil pump are integrated into an oil tank, an oil cylinder is connected with a high-integration-level oil station through an internal oil pipeline, the purpose of completely removing external oil pipes is achieved, all the internal oil pipes and corresponding valves are arranged in hydraulic valve blocks, and the purposes of high integration, size reduction, compact structure and low cost are achieved. The oil cylinder is directly connected with the actuating rod component, so that the force output efficiency of the oil cylinder is improved, and meanwhile, the switch machine can easily finish the operation of manually switching the turnout by additionally arranging the hydraulic control pressure relief valve.

    本发明涉及铁路交通设备技术领域,尤其涉及一种电液转辙用高集成度液压总成,包括液压阀块,以及固定在液压阀块上的连接板,以及固定设置在连接板一侧的油箱,以及固定设置在液压阀块上的活塞杆,以及能活动设置在活塞杆上的油缸,其中,油箱内部设置有油泵和油浸式电机,所述油泵和油浸式电机固定连接。通过使用油浸式电机,将电机、油泵集成到油箱内部,油缸与高集成度油站通过内部油管路连接,达到完全去除外接油管的目的,将内部所有的油管以及相应的阀门均设置在各液压阀块内,达到高度集成,减小体积,使结构紧凑,将油缸与动作杆部件直连,提高油缸力输出效率,同时通过外加液控卸压阀使转辙机能轻松完成手动转换道岔的操作。
