The hydraulic stepping lifting device comprises a rack, a transverse channel and a longitudinal channel which are communicated with each other are arranged in the rack, a plurality of stepping lifting stand columns are stacked in the longitudinal channel and extend out of the longitudinal channel, and the extending parts of the stepping lifting stand columns are sleeved with rectangular ring beams; a bearing tray is arranged on the top face of the stepping lifting stand column on the topmost portion. A plurality of lifting hydraulic cylinders are mounted on the top surface of the rack, piston rods of the lifting hydraulic cylinders face upwards and can synchronously ascend and descend, and the tops of the piston rods of the lifting hydraulic cylinders are hinged to the bottom surface of the rectangular ring beam; a guide rail conveying device is installed on one side of the rack, and the output end of the guide rail conveying device is located in the transverse channel of the rack and located below the longitudinal channel. The jacking device has the remarkable advantages of being easy to install and maintain, small in occupied space, high in bearing capacity, large in jacking height, convenient to transport, high in lifting horizontal precision, high in stability, high in safety performance and the like.

    本发明公开了一种液压步进升降装置,包括有机架,机架内设有相互贯通的横向通道和纵向通道,纵向通道内叠放有若干步进升降立柱且步进升降立柱伸出纵向通道外,步进升降立柱的伸出部分套有矩形环梁;最顶部的步进升降立柱顶面上设有承重托盘;所述机架顶面安装有若干活塞杆朝上且活塞杆可以同步升降的升降液压缸,所述升降液压缸的活塞杆顶部均铰接在矩形环梁的底面上;机架一侧安装有导轨传送装置,导轨传送装置的输出端位于机架的横向通道内且位于纵向通道的下方。本发明具有安装及维护简单、占用空间小、承重能力强、顶升高度大、运输方便、升降水平精度高、稳定性强及安全性能高等显著优点。
