The invention discloses an electro-hydraulic switch machine for a railway turnout, which solves the technical problems of asynchronous switching, large equipment structure and easy oil leakage in the prior art, and belongs to the technical field of railway traffic equipment, and adopts the specific technical scheme that the electro-hydraulic switch machine comprises a machine shell, an independent oil supply pump and an electric motor are arranged in the machine shell; the oil supply pump is connected with an output shaft of the motor through a coupler, the oil supply pump provides power for the action oil cylinder, the first locking oil cylinder and the second locking oil cylinder, a cylinder barrel of the action oil cylinder is connected with the trailable body through the action plate, and the cylinder barrel of the action oil cylinder, the trailable body and the action rod move synchronously. After the first locking oil cylinder and the second locking oil cylinder start to move to a certain position, the locking rod and the contact driving rod are driven to move, so that the contacts are switched, the action oil cylinder and the locking oil cylinder of the switch machine are independently designed, the independent switching and locking functions are achieved respectively, and synchronous operation of turnout switching under multi-machine traction can be guaranteed.

    本发明公开了一种铁路道岔用电液转辙机,解决了现有技术存在的转换不同步、设备结构大、易漏油的技术问题,属于铁路交通设备技术领域,具体技术方案为:包括机壳,机壳内设有独立的供油泵和电动机,供油泵通过联轴器与电动机的输出轴相连,供油泵为动作油缸、第一锁闭油缸和第二锁闭油缸提供动力,动作油缸的缸筒通过动作板与挤脱体相连,动作油缸缸筒、挤脱体与动作杆同步运动,转辙机转换到位时,第一锁闭油缸和第二锁闭油缸开始移动至一定位置后,驱动锁闭杆和接点驱动杆移动,从而将接点进行转换,转辙机的动作油缸和闭锁油缸都单独设计,分别实现独立的转换和闭锁功能,能够保证多机牵引下的道岔转换同步运行。
