Ship lift anti-collision beam hydraulic system
The ship lift anti-collision beam hydraulic system comprises an oil tank and a motor, the oil tank comprises an oil return path and a supply path, the oil return path and the supply path are communicated in series through a pipeline, a safety valve is arranged on the pipeline, and the pipeline is divided into a supply pipeline and an oil return pipeline through the safety valve; a variable pump and a first one-way valve are sequentially connected to the supply pipeline in series, and the variable pump is arranged close to the oil tank and driven by the motor. A first ball valve is arranged at the output end of the one-way valve; a pressure compensator is communicated between the output end of the first ball valve and the oil inlet of the proportional reversing valve; the oil return pipeline is communicated with a second one-way valve, and the input end of the second one-way valve and an oil way communicated between the first ball valve and the pressure compensator are communicated with a cartridge valve set in parallel. A hydraulic loop for driving the piston rod of the oil cylinder to push out the anti-collision beam to descend is changed into a differential loop, so that the descending time of the anti-collision beam is greatly prolonged, the navigation efficiency of the ship lift is improved, and the system configuration and cost are reduced.
本发明公开了一种升船机防撞梁液压系统，包括油箱以及电机，油箱包括回油路以及供给路，其中：回油路和供给路通过管道进行串联连通，且该管道上设置有安全阀，并通过安全阀使管道分为供给管路和回油管路；供给管路上依次串联有变量泵和第一单向阀，变量泵靠近油箱布置，并受电机驱动；单向阀的输出端设置有第一球阀，第一球阀输出端与比例换向阀进油口之间连通有压力补偿器；回油管路上连通有第二单向阀，第二单向阀输入端和第一球阀与压力补偿器之间连通的油路上并联连通有插装阀组。该发明将驱动油缸活塞杆推出防撞梁下降液压回路改为差动回路，大幅提升防撞梁的下降时间，提高升船机通航效率，降低系统配置和成本。
