The invention discloses a lifting hydraulic control system, and relates to the technical field of hydraulic control systems. The lifting hydraulic control system comprises an oil inlet pipeline, an oil return pipeline, an oil inlet control valve group and an oil return control valve group, two ends of the oil return pipeline are separately used for communicating oil cavities in an oil tank and an oil cylinder, and two ends of the oil inlet pipeline are separately used for communicating oil cavities in the oil tank and the oil cylinder. The oil inlet control valve group is arranged on the oil inlet pipeline, and the oil return control valve group is arranged on the oil return pipeline. The oil inlet control valve group comprises a one-way valve and a power mechanism, the power mechanism is used for providing power for hydraulic oil in the oil tank to flow towards the oil cavities, and the one-way valve only allows the hydraulic oil in the oil inlet pipeline to flow into the oil cavities from the oil tank. The oil return control valve group comprises a first plug-in mounting direction valve arranged on the oil return pipeline and an electromagnetic ball valve for controlling the on-off of the first plug-in mounting direction valve. According to the scheme of the lifting hydraulic control system, the stability of the system is improved, the phenomenon that a lifting platform suddenly slides down when a worker works is prevented, the safety and reliability of equipment are ensured, and the personal safety of the worker is ensured.
本发明公开了一种升降液压控制系统,涉及液压控制系统技术领域,包括进油管路、回油管路、进油控制阀组和回油控制阀组,回油管路的两端分别用于连通油箱和油缸中的油腔,进油管路的两端分别用于连通油箱和油缸中的油腔,进油控制阀组设置于进油管路上,回油控制阀组设置于回油管路上;进油控制阀组包括单向阀和动力机构,动力机构用于给油箱内的液压油一朝向油腔流动的动力,单向阀仅允许进油管路中的液压油从油箱流至油腔内;回油控制阀组包括设置于回油管路上的第一插装方向阀和控制第一插装方向阀通断的电磁球阀。本发明提供的方案提高了系统的稳定性,防止升降平台在工人工作的时候出现突然下滑的现象,保证设备安全可靠,保证工人人身安全。
