Hydraulic system of lifting platform
The invention provides a hydraulic system of a lifting platform. The hydraulic system comprises a drive pump module, an oil distributing module, an oil tank and at least two motor modules. The drive pump module comprises a main pump and a two-position four-way valve. The motor modules are provided with first oil ports, second oil ports and hydraulic brakes. The oil distributing module comprises afirst shuttle valve and a two-position three-way valve. A first oil inlet of the first shuttle valve is connected to oil ways of a second oil port of the two-position four-way valve and first oil ports of the motor modules, a second oil inlet of the first shuttle valve is connected to oil ways of a third oil port of the two-position four-way valve and second oil ports of the motor modules, a firstoil port of the two-position three-way valve communicates with the oil tank, a second oil port of the two-position three-way valve communicates with an oil outlet of the first shuttle valve, and an oil inlet of each hydraulic brake communicates with a third oil port of the two-position three-way valve. Oil can be controlled to simultaneously enter the hydraulic brakes of different lifting units,so that the oil pressure of the oil in the hydraulic brakes of the different lifting units is consistent.
本公开提供了一种升降平台的液压系统，包括：驱动泵模块、油液分配模块、油箱和至少两个马达模块；驱动泵模块包括主泵和二位四通阀，马达模块具有第一油口、第二油口和液压制动器；油液分配模块包括：第一梭阀和二位三通阀，第一梭阀的第一进油口连接在二位四通阀的第二油口和马达模块的第一油口的油路上，第一梭阀的第二进油口连接在二位四通阀的第三油口和马达模块的第二油口的油路上，二位三通阀的第一油口与油箱连通，二位三通阀的第二油口与第一梭阀的出油口连通，每个液压制动器的进油口均与二位三通阀的第三油口连通。本公开能控制油液同时进入不同升降单元的液压制动器，且使不同升降单元的液压制动器中的油液的油压一致。
