Abstract
The invention discloses a synchronous-control hydraulic station of oil cylinders. The synchronous-control hydraulic station of oil cylinders is used for solving the technical problem that a conventional synchronous-control hydraulic station of oil cylinders is high in vibrating noise. The synchronous-control hydraulic station of oil cylinders adopts the technical scheme that the synchronous-control hydraulic station comprises a hydraulic oil tank, an air cooler, power systems, synchronous valve blocks, reversing valve blocks and an oil cooling pump, wherein the hydraulic pumps of the power systems are positioned in the hydraulic oil tank; the synchronous valve blocks, the reversing valve blocks and the air cooler are integrated on a cover plate at the top of the hydraulic oil tank. When the synchronous-control hydraulic station of oil cylinders works, the vibration of the hydraulic pumps of the power systems is weakened by hydraulic oil, so that the vibrating noise generated by the power systems is reduced. When the synchronous-control hydraulic station of oil cylinders works, reversing impact generated by the reversing valve blocks during working is transferred to the whole hydraulic oil tank through the cover plate of the hydraulic oil tank; due to the vibration absorbing effect of the hydraulic oil, the impact vibration of the reversing valve blocks is weakened, so that the vibrating noise of the whole station is reduced. The working oil ports of the synchronous valve blocks only need to be connected with the rodless cavity oil ports of the synchronous oil cylinders, so that the pipeline connection is simple.
