The invention provides a hydraulic heavy type lifting device, and relates to the technical field of lifting devices, the hydraulic heavy type lifting device comprises two sets of rails and two sets of sliding blocks, each set of rails is movably provided with two sets of sliding blocks, the sliding blocks are provided with a steel frame, and the two ends of the bottom of the steel frame are each provided with a first hydraulic cylinder; the output end of the first hydraulic cylinder penetrates through the top of the steel frame and is provided with a first lifting plate, a telescopic column is arranged in the middle of the bottom of the first lifting plate and movably penetrates through the top of the steel frame, and a mounting groove is formed in the telescopic column. According to the four-point lifting device, the four sets of lifting assemblies are used for lifting large workpieces at four points, the sliding blocks move along the rails, the distance between the two sets of connecting beams is changed, the movable frames move along the connecting beams, the distance between the adjacent movable frames is changed, and the positions of the four sets of lifting assemblies are adjusted, in conclusion, four-point lifting is more stable, the workpieces are not prone to shaking, and the four workpieces can be adjusted; and the device adapts to the sizes of different large workpieces.

    本发明提供了一种液压重型提升装置,涉及提升装置技术领域,包括轨道和滑块,所述轨道设有两组,每组所述轨道上均活动设有两组所述滑块,所述滑块上设有钢架,且钢架底部的两端均设有第一液压缸,所述第一液压缸的输出端贯穿钢架顶部并设有第一提升板,所述第一提升板底部的中间位置处设有伸缩柱,且伸缩柱活动贯穿所述钢架的顶部,所述伸缩柱的内部设有安装槽;本发明通过四组吊连组件四点吊运大型工件,通过滑块沿着轨道运动,改变两组连接梁之间的间距,通过活动框沿着连接梁运动,改变相邻活动框之间的间距,调整四组吊连组件的位置,综上,四点吊运,更加稳定,工件不易晃动,且四件可以调节,适配不同大型工件的尺寸。
