The invention provides a multipoint PLC synchronous jacking hydraulic device and system, and relates to the technical field of hydraulic jacking. The device comprises a hydraulic pump station, a control assembly and an oil cylinder assembly. The hydraulic pump station and the oil cylinder assembly are connected by hydraulic hoses. The oil cylinder assembly comprises a plurality of groups of lifting oil cylinders, wherein each lifting oil cylinder comprise an oil cylinder body and lifting ropes which are arranged on the oil cylinder bodies and move relatively along movement of the oil cylinderbodies. The control assembly is a displacement sensor arranged for detecting the relative height position of the lifting cylinder. By arrangement of the hydraulic pump station and the plurality of groups of lifting cylinders, the system can lift all stress points of an object to be lifted simultaneously, lifting accuracy and safety factor are improved, and by means of the structural form of the lifting ropes, so that irregular large objects can be lifted, and operation is convenient, time and labor are saved. The system comprises the device and has the beneficial effects of the device.

    本发明提出了一种多点PLC同步顶升液压装置及系统,涉及液压顶升技术领域。该装置包括液压泵站、控制组件和油缸组件。液压泵站和油缸组件通过液压软管相互连接。油缸组件包括若干组提升油缸,提升油缸包括油缸本体和提升绳,提升绳设置于油缸本体上,且沿油缸本体的运动而相对移动。控制组件为位移传感器,位移传感器被设置用于检测提升油缸的相对高度位置。该装置能够通过设置液压泵站和若干组提升油缸,使得该系统能对待举升物体的各个受力点同时举升,提高了举升精度和安全系数,同时,采用提升绳的结构形式,利于举升不规则的大型物体,操作简便,省时省力。该系统包括上述装置,具有其所有有益效果。
