Hydraulic system for pin type lifting platform
The invention provides a hydraulic system for a pin type lifting platform. The hydraulic system involves a first driving pump, a second driving pump, an oil liquid distribution module, a first liftingoil cylinder, a first oil way control module, a second lifting oil cylinder, a second oil way control module and an oil tank, wherein an oil outlet of the first driving pump communicates with a firstoil inlet of the oil liquid distribution module, a rod cavity and a rodless cavity of the first lifting oil cylinder communicate with a first oil outlet of the oil liquid distribution module, an oiloutlet of the second driving pump communicates with a second oil inlet of the oil liquid distribution module, a rod cavity and a rodless cavity of the second lifting oil cylinder communicate with a second oil outlet of the oil liquid distribution module, the oil liquid distribution module is provided with a first state and a second state, the first oil way control module is provided with a first state and a second state, and the second oil way control module is provided with a first state and a second state. According to the hydraulic system for the pin type lifting platform, hydraulic pumps with different displacements can be used for controlling an upper ring beam and a lower ring beam which bear different loads, so that the power and the cost of the hydraulic system are reduced.
本公开提供了一种插销式升降平台的液压系统，包括：第一驱动泵、第二驱动泵、油液分配模块、第一提升油缸、第一油路控制模块、第二提升油缸、第二油路控制模块和油箱，第一驱动泵的出油口与油液分配模块的第一进油口连通，第一提升油缸的有杆腔和无杆腔均与油液分配模块的第一出油口连通，第二驱动泵的出油口与油液分配模块的第二进油口连通，第二提升油缸的有杆腔和无杆腔均与油液分配模块的第二出油口连通，油液分配模块具有第一状态和第二状态，第一油路控制模块具有第一状态和第二状态，第二油路控制模块具有第一状态和第二状态。本公开能采用不同排量的液压泵控制承受不同载荷的上环梁和下环梁，降低液压系统功率和成本。
