The invention discloses a liftable multi-connecting-rod mechanism which comprises a first supporting base, a second supporting base, a sliding rail, a triangular arm, a supporting arm and a hydraulic cylinder, the first supporting base, the second supporting base and the sliding rail are fixedly arranged on a fixing frame, and the three ends of the triangular arm are connected with the first supporting base through first rotating shafts correspondingly; the sliding rail is connected with one end of a hydraulic cylinder through a second rotating shaft and connected with the middle of a supporting arm through a third rotating shaft, the supporting arm is arranged in the sliding rail in a sliding mode through a sliding block, and the end, away from the second rotating shaft, of the hydraulic cylinder is connected with the second supporting base through a fourth rotating shaft. The lifting device has the following advantages that the structural design is reasonable, the lifting device is of a parallel structure, strict vertical lifting can be achieved, the bearing capacity is large, and high-speed lifting can be easily achieved through expansion.

    本发明公开了一种可升降的多连杆机构,包括第一支撑底座、第二支撑底座、滑轨、三角臂、支撑臂、液压缸、其中第一支撑底座、第二支撑底座、滑轨固定设置在固定架上,所述三角臂的三端分别通过第一转轴与第一支撑底座相连接,通过第二转轴与液压缸的一端相连接,通过第三转轴与支撑臂的中部相连接,所述支撑臂通过滑块可滑动设置于滑轨内,所述液压缸远离第二转轴的一端通过第四转轴与所述第二支撑底座相连接。本发明具有如下优点:结构设计合理,升降装置为并联结构,可实现严格意义的垂直升降,承载能力大,通过扩展易于实现高速升降。
