The invention provides a lifting device based on transformer maintenance. The lifting device comprises a supporting base, wherein two rectangular supporting blocks are symmetrically arranged on the supporting base, a hydraulic cylinder is mounted on the supporting base, and a lifting lever is mounted between the two hydraulic cylinders; the supporting base is formed by buckling two parts, a pushing mechanism in threaded sliding connection is mounted on the supporting base, and a hand wheel is mounted on the pushing mechanism; and an extrusion mechanism is clamped in the supporting base. According to the lifting device, an inclined block is arranged on the pushing mechanism and can be pushed to move when the hand wheel of the pushing mechanism is rotated, so that the inclined block pushes an extrusion block to move downwards, the extrusion block pushes a clamping base to expand towards the two sides, the clamping base is clamped and fixed to a mounting base of the hydraulic cylinder, and the bottom of the device is fixed; and compared with contrast files, the operation is relatively simple when the base is fixed, certain working time is saved, and the service life is relatively long.

    本发明提供一种基于变压器维修的升降装置,包括支撑座;支撑座上对称设有两个矩形支撑块,且支撑座上安装有一个液压缸,两个液压缸之间均安装有抬杠;支撑座由两部分扣合而成,且支撑座上安装有螺纹滑动连接的推动机构,推动机构上安装有手轮;支撑座的内部卡接有挤压机构。在推动机构上设置有斜块,转动推动机构的手轮时会推动斜块移动,从而使斜块推动挤压块向下移动,挤压块推动夹紧座向两侧扩张,使得夹紧座夹紧固定在液压缸的安装座上,实现本发明底部的固定,与对比文件相比较,底座在固定时操作相对简单些,节省一定的工作时间,使用寿命也相对较长些。
