The invention relates to the technical field of hydraulic systems, in particular to a synchronous oil cylinder. According to the adopted technical scheme, the synchronous oil cylinder comprises a cylinder body, wherein a first oil cavity and a second oil cavity which are the same in size are formed inside the cylinder body, a first piston is arranged inside the first oil cavity in a matched mode,a second piston is arranged inside the second oil cavity in a matched mode, and the first piston is fixedly connected with the second piston. When the synchronous oil cylinder is used, hydraulic oil drives the first piston and the second piston to act synchronously, it can be guaranteed that the oil amount of the hydraulic oil output from the first oil cavity and the oil amount of the hydraulic oil output from the second oil cavity are the same to guarantee synchronism of actions of two jacking hydraulic cylinders of a formwork; and meanwhile, extendable control over the jacking hydraulic cylinders of the formwork can be achieved only by controlling the flow direction of the hydraulic oil through a reversing valve, and therefore the synchronous oil cylinder has the characteristics of beingsimple in structure, high in synchronism, easy to control and high in reliability.

    本发明涉及液压系统技术领域,具体涉及一种同步油缸;所采用的技术方案为:一种同步油缸,包括缸体,所述缸体内设有尺寸相同的第一油腔和第二油腔,所述第一油腔内适配有第一活塞,所述第二油腔内适配有第二活塞,所述第一活塞和第二活塞固定连接。本发明使用时由液压油驱动第一活塞和第二活塞同步动作,能够确保从第一油腔和第二油腔输出的液压油油量相同,以确保模架的两顶升液压缸动作的同步性;同时只需通过换向阀控制液压油的流向即可实现模架顶升液压缸的伸缩控制,因此本发明具有结构简单、同步性高、控制简单和可靠性高的特点。
