The invention relates to the technical field of underwater lifting devices, and provides an air cushion buffering type multi-stage pneumatic lifting system which comprises a lifting device and a pneumatic loop, the lifting device comprises a base, a first-stage lifting rod, a second-stage lifting rod and a third-stage lifting rod, and the first-stage lifting rod, the second-stage lifting rod and the third-stage lifting rod are sequentially and coaxially arranged on the inner side of the base from outside to inside and can be unfolded towards the upper portion of the base step by step; wherein the lifting device sequentially forms a first recovery cavity, a second recovery cavity and a third recovery cavity from outside to inside, a first connector penetrating through the base is arranged on the upper portion of the base, the bottom of the base is fixedly connected with the bottom cover, a second connector penetrating through the bottom cover is arranged on the bottom cover, and the top of the three-level lifting rod is fixedly connected with the plug. According to the air cushion buffering type multi-stage pneumatic lifting system, all stages of lifting rods can be more accurately controlled to stretch out and retract completely and stably, and the air tightness of the lifting system is improved.

    本发明涉及水下升降装置技术领域,提供一种气垫缓冲式多级气动升降系统,包括升降装置和气动回路,升降装置包括底座以及由外向内依次同轴心设置在底座内侧并能够向底座上方逐级展开的一级升降杆、二级升降杆和三级升降杆,其中,升降装置由外向内依次形成第一收回腔、第二收回腔和第三收回腔,底座的上部设置贯通底座的第一接头,底座的底部与底盖固定连接,底盖上设置贯通底盖的第二接头,三级升降杆的顶部与堵头固定连接。根据本实施例的气垫缓冲式多级气动升降系统,可以更加精确地控制各级升降杆的完全且平稳的伸出和收回,提高升降系统的气密性。
