Lifting system for realizing automatic leveling and centering of box body

The invention belongs to the technical field of nuclear power, and particularly relates to a lifting system for achieving automatic leveling and centering of a box. The lifting ring assembly comprises a plurality of adjusting modules and a plurality of arc-shaped connecting rings, each adjusting module comprises a driving unit and an aligning mechanism, the adjusting modules are fixedly connected through the arc-shaped connecting rings, the adjusting modules are symmetrically and evenly distributed around the same axis, and the lifting ring assembly synchronously moves through the driving units to achieve overall lifting. Therefore, stable lifting of the product in the vertical direction is achieved, and the device can be widely applied to a follow-up rocket storage tank friction stir welding system. 本公开属于核电技术领域，具体涉及一种用于实现箱体自动调平及对心的提升系统。本公开中提升环组件包括多个调整模块和多个弧形连接环，每个调整模块包括驱动单元和调心机构，各调整模块之间通过弧形连接环固定连接，各调整模块围绕同一轴心对称均匀分布，提升环组件通过驱动单元同步运动实现整体升降，由此实现产品在竖直方向的平稳提升，在后续的火箭贮箱搅拌摩擦焊接系统中，将会得到非常广泛的应用。
