The invention discloses an axially expandable jacking mechanism which comprises a jacking mechanism body, a large circular ring, a bearing, a small circular ring and a middle circular ring are arranged on the jacking mechanism body, the large circular ring, the bearing and the small circular ring form a static platform, the middle circular ring is a movable platform, and six UU branched chains are arranged between the static platform and the movable platform. The six UU branch chains comprise three follow-up supporting rods and three active movement supporting rods, branch chain universal connectors are arranged at the two ends of the follow-up supporting rods and the two ends of the active movement supporting rods, the branch chain universal connectors and the circular rings are installed in a matched mode, the jacking mechanism is small in occupied space when being contracted and large in space when being unfolded, the space utilization rate is increased, and the space utilization rate is increased. The jacking mechanism belongs to a single degree of freedom, can realize single-drive input, achieves a jacking effect by driving the axial movement of the middle circular ring through the rotation of the small circular ring, and has the advantages of simple structure, higher bearing capacity, flexibility in operation, high space utilization rate, large movement space, easiness in modular manufacturing and the like.
本发明公开了一种可轴向扩展的顶升机构,包括顶升机构本体,顶升机构本体上设有大圆环、轴承、小圆环、为中圆环,所述大圆环、轴承、小圆环构成静平台,所述中圆环为动平台,静平台与动平台之间设有6条UU支链,6条UU支链上包括3根随动支撑杆与3根主动运动支撑杆,在随动支撑杆与主动运动支撑杆的两端端头均设有支链万向连接头,支链万向连接头与圆环配合安装,该顶升机构收缩时所占空间小,展开时空间大,提高了空间利用率,该顶升机构属于单自由度,可实现单驱动输入,通过小圆环的转动驱动中圆环的轴向移动达到顶升效果,具有结构简单、承载能力较高、操作灵活、空间利用率高、运动空间大、易于模块化制造等优点。
