The invention relates to rotary lifting equipment suitable for cleaning the inside of an oil storage tank, which comprises a vertical oil storage tank, and a guide unit and a rotary lifting unit which are arranged in the vertical oil storage tank, and an adaptive access hole is formed in the top of the vertical oil storage tank; the guide unit comprises a straight track and a spiral track, the rotary lifting unit comprises a driving motor and a lifting motor, and a safety locking unit is mounted in the rotary lifting unit; the safety locking unit comprises a rotating disc, four inserting holes are formed in the surface of the rotating disc, and a pressing rod is arranged in each inserting hole in an inserted mode. According to the device, by arranging the safety locking unit and the rotary lifting unit, after a driving motor is damaged, the whole device has the downward movement tendency to drive a positioning gear, a rotary shaft and a rotary disc to rotate, a notch in the surface of a pressing rod at the top is clamped to the edge of a special-shaped assembly, and therefore the locking purpose is achieved; and the safety protection effect is achieved. The method is suitable for wide popularization and use.

    本发明涉及一种适用石油储罐内清洁的旋转式升降设备,包括立式石油储存罐以及安装在立式石油储存罐内部的导向单元和旋转升降单元,立式石油储存罐顶部开设有适配的检修口;导向单元包括平直轨道和螺旋轨道,旋转升降单元包括驱动电机和升降电机旋转升降单元内部安装有安全锁止单元;安全锁止单元包括转盘,转盘表面开设有四个插孔,每个插孔内部插接设置有压杆。本发明,通过设置有安全锁止单元和旋转升降单元,当驱动电机发生损害后,装置整体有着向下运动的趋势,带动定位齿轮、旋转轴和转盘旋转,将顶部的压杆表面的缺口卡接在异形组件的边沿处,从而达到了锁止的目的,起到了安全保护的作用。适合广泛推广和使用。
