The invention relates to a movable hydraulic lifting workbench. The movable hydraulic lifting workbench comprises an electric vehicle, a lifting oil cylinder, a gear oil pump and a driving motor, wherein a frame of the electric vehicle is provided with a plurality of segments of frameworks which are overlaid together; the first segment is a fixed framework; the rest are lifting frameworks; the first segment of fixed framework is fixed to the frame of the electric vehicle; a supporting plate is fixedly connected with the extension end of the lifting oil cylinder; the supporting plate is fixedlyconnected with the second segment of lifting framework through four connecting rods; four fixed pulleys are uniformly distributed on the top of each segment of lifting framework from the second segment of lifting framework; the fixed pulleys are wound with steel wire ropes; one end of each steel wire rope is connected with the four bottom corners of the first segment of fixed framework; the otherends of the steel wire ropes are connected with the four bottom corners of the last segment of lifting framework; a hydraulic cylinder of the lifting oil cylinder rises to support the supporting plate; the supporting plate is used for driving the second segment of lifting framework to rise through the connecting rods; and the second segment of lifting framework is used for driving the third segment of lifting framework to rise through the fixed pulleys and the steel wire ropes, and so on, so that a working cycle is completed.
本发明涉及一种可移动式液压升降工作平台,包括电动车、升降油缸、齿轮油泵、驱动电机,电动车的车架上设置有多节叠加在一起的框架,第一节为固定框架,其余为升降框架,第一节固定框架固定在电动车的车架上,升降油缸伸出端固接有支撑板,支撑板通过四根连接杆与第二节升降框架固定连接,从第二节升降框架起每一节升降框架的顶部均布有四个定滑轮,定滑轮上绕有钢丝绳,钢丝绳一端与第一节固定框架的四个底角相连接,钢丝绳另一端与上一节升降框架的四个底角相连接,升降油缸的液压缸上升顶起支撑板,支撑板通过连接杆带动第二节升降框架上升,第二节升降框架通过定滑轮和钢丝绳带动第三节升降框架上升,以此类推,一个工作循环完成。
