Intelligent separate control type hydraulic synchronous jacking system and method for replacing bridge support through same
An intelligent separate control type hydraulic synchronous jacking system comprises a jacking device, a hydraulic system and a control system. The jacking device comprises n lifting jacks. The hydraulic system comprises a frequency-variable motor, a starting box for controlling the frequency-variable motor to start and stop, n sets of multi-port and multi-pressure-output unit radial plunger pump heads and a valve set arranged between a lifting jack oil cylinder and the plunger pump heads. The valve set comprises an unloading electromagnetic valve, an overflow valve, an electromagnetic reversing valve, a hydraulic lock, a safety valve and a balancing valve. The n sets of unit radial plunger pump heads are driven by the same frequency-variable motor. Each set of unit radial plunger pump head corresponds to one lifting jack. The control system comprises an upper computer, a master control box, a pressure sensor and a displacement sensor, and 2<=n<=48. The intelligent separate control type hydraulic synchronous jacking system adopts a separate control and intelligent control mode, the unit radial plunger pump heads are used for independently controlling the lifting jacks and carry out double-closed-loop control over the stress and displacement of the lifting jacks, the stress and displacement of the lifting jacks are automatically controlled, and the synchronization performance is good.
