The invention provides a PLC hydraulic proportional synchronous jacking system for bridge jacking, and relates to the technical field of constructional engineering. The PLC hydraulic proportional synchronous jacking system for bridge jacking comprises a master control module, a hydraulic pump set connection control module, a system valve control module, a plurality of sets of hydraulic jacking device modules and a PLC line operation monitoring module. The output end of the master control module is electrically connected with the input end of a hydraulic pump set connection control module and the input end of a system valve control module. By arranging the independent master control module, multiple sets of hydraulic jacking device modules can be controlled in an independent bus mode, the situation that when a single line breaks down, other jacking assemblies connected with a PLC element cannot stop synchronously at once can be avoided, by arranging the independent secondary line switching module, line switching can be rapidly completed, and the working efficiency is improved. Normal operation of the jacking system is recovered, and influence of system faults on bridge jacking operation is avoided.
本发明提供一种用于桥梁顶升的PLC液压比例同步顶升系统,涉及建筑工程技术领域。该用于桥梁顶升的PLC液压比例同步顶升系统,包括总控模块、液压泵组连接控制模块、系统阀门控制模块、多组液压顶升装置模块和PLC线路运行监测模块,所述总控模块的输出端分别电性连接液压泵组连接控制模块与系统阀门控制模块的输入端。通过设置独立的总控模块,可以对多组液压顶升装置模块以独立总线的方式进行控制,可以避免在单条线路发生故障时,其它与PLC元件连接的顶升组件不会立刻同步停止,并且通过设置独立的二级线路转接模块,可以快速完成线路转接,恢复顶升系统的正常运作,避免系统故障影响桥梁顶升作业。
