<p class="p__0">Summary of the invention The item of this creation is to supply a type of PLC hydraulic proportional synchronous jacking system for bridge jacking, embrace this system efficiently the existing bridge in city to be transformed and to be promoted. The present invention is that the technical plan that its technical issue of service adopts is, A PLC hydraulic proportional synchronous jacking system for bridge jacking, comprises hydraulic jacking system, finds sensor-based system and computer control system, where: Hydraulic jacking system, consists of the lots of groups hydraulic jack for jacking bridge, organizes hydraulic jack more and connects hydraulic power unit, is also supplied with pressure sensor on hydraulic jack; Find sensor-based system, consist of for detection of the stay wire displacement sensing unit of bridge jacking displacement and the pressure sensing unit on hydraulic jack; Computer system control system, comprises that PLC controller also connects a computer system console for the PLC controller to pumping plant pipage control signal; Pressure sensing unit and stay wire displacement sensing unit are transferred to PLC controller and computer system console by circuit by signal feedback.</p>

<p class="p__1">Described stay wire displacement sensing unit is 14. The precision of stay wire displacement sensor is 2. 0mm. The creation has the advantages that, embrace PLC to manage the jacking speed that hydraulic jack ratio simultaneous jacking system is properly controlled jack, recognize the ratio synchronization of boosting of bridge.</p>

<p class="p__2">By hydraulic jack, properly according to the actual loading of bridge, jacking bridge reposefully, the subsidiary tension that jacking procedure Bridge undergoes drops to minimum. In More Discussion Posted Here , hydraulic jack is divided into 16 groups according to dispersing position, by 8 pumping station with extra-high voltage, a set of control system, displacement detector etc., type position closed loop with corresponding 14 displacement transducers (stay wire sensing unit), to manage displacement and the mindset of bridge jacking, synchronization accuracy is 2.</p>
<br>
<p class="p__3">The particular embodiment For technological methods, development characteristic that the present development is realized, reach item and effect is easy to understand, below in combination with diagram and specific personification, additional state the present creation. System the key technical indexes explained in today embodiment 1. 1 General Requirements Hydraulic system working pressure: 63.</p>
