The invention discloses a template synchronous hydraulic jacking control system. The template synchronous hydraulic jacking control system solves the problems that the number of wiring wires of an existing system is large, a control interface of an operation box is complicated, the cost is higher, and the synchronization is not high. The template synchronous hydraulic jacking control system includes a small hydraulic station and a centralized electrical control system. The small hydraulic station is used as a lifting driving device of a single template, a one-inlet and two-outlet synchronous hydraulic motor device is arranged in the system, and at the same time, two secondary pressure regulating valves are arranged at the outlet ends of the hydraulic motor to regulate the pressure, so thathigh-precision synchronous jacking of two oil cylinders is realized. Each outlet of the hydraulic motor is connected with an electromagnetic reversing valve, and outlets of the electromagnetic reversing valves are connected with the oil cylinders. The template synchronous hydraulic jacking control system has short arranged pipelines, less wire wiring, low pressure loss, high synchronization precision and low cost. An operation interface of the control system is clear and simple, is convenient to operate, and can realize jacking of a single oil cylinder, jacking of two oil cylinders of a single set of templates and jacking of a plurality of oil cylinders of a plurality of sets of templates. When the templates need to be moved to other positions, cables of the motor and the electromagneticreversing valves can be removed to achieve integral movement, and the efficiency is high and no pollution is caused.
Description
technical field [0001] The invention relates to a synchronous hydraulic jacking control system for a climbing formwork. Background technique [0002] At present, during the construction of hydropower dams, hydraulic self-climbing cantilever formwork is introduced into the construction of dam transverse joint formwork to solve the problem that the site formwork cannot be hoisted and constructed due to strong winds. The width of the transverse joint surface of the arch dam changes with the elevation, so the number of blocks arranged on the transverse joint hydraulic cantilever formwork on the transverse joint surface changes continuously according to the elevation. In order to facilitate the layout of the hydraulic self-climbing cantilever formwork, a single set of hydraulic self-climbing cantilever formwork includes two climbing rails and two driving cylinders to realize the stable and independent climbing of a single formwork and avoid collision interference between formwork...
