The hydraulic lifting mechanism comprises a hydraulic rod and a bracket connected to a bottom frame through a shear fork assembly, the shear fork assembly comprises a first fork rod and a second fork rod, the middles of the first fork rod and the second fork rod are hinged together through a middle hinged shaft, the lower end of the first fork rod is hinged to the bottom frame, and the upper end of the first fork rod is slidably connected with the bracket; the upper end of the second fork rod is hinged to the bracket, the lower end of the second fork rod is in sliding connection with the bracket, the bracket comprises a main frame matched with the shear fork assembly, a sliding frame arranged on the main frame and a carrier connected to the sliding frame in a sliding mode, a vertical linkage push rod with a vertical sliding groove formed in the lower end is fixedly connected to the lower surface of the geometric center of the carrier, and a middle hinged shaft penetrates through the vertical sliding groove. The lifting device has the advantage that the gravity center of a lifted object is always maintained at the geometric center of the supporting surface, and solves the problem that the lifting device is easy to damage due to the fact that the gravity center of the object is not changed when the shear fork assembly translates on one side when the shear fork assembly translates on one side in the lifting process of an existing lifting device.

    本发明提供一种重心动态变化的液压升降机构,包括液压杆和通过剪叉组件连接在底架上的托架,剪叉组件包括中部通过中部铰轴铰接在一起的第一叉杆和第二叉杆,第一叉杆的下端与底架铰接、上端与托架滑动连接,第二叉杆的上端与托架铰接、下端与托架滑动连接,托架包括与剪叉组件配合的主架、设置于主架的滑动架、滑动连接在滑动架上的载物架,载物架几何中心处的下表面上固接有下端设竖滑槽的竖联动推杆,中部铰轴穿设在竖滑槽内。本发明旨具有被举升物体的重心始终维持在支撑面的几何中心的优点,解决了现有的升降装置升降过程中物体重心不变所存在的剪叉组件为单侧平移时物体的重心容易偏离剪叉组件的中心导致升降装置容易损坏的问题。
