The invention discloses a hybrid drive lifting device which comprises a lifting assembly and a driving assembly, the lifting assembly comprises a lifting part and a sliding part, the lifting part is telescopic, the sliding part is slidably connected to the lifting part in the axial direction of the lifting part, the driving assembly comprises a driving part and a pulley part, the driving part is provided with a fixed end and an extension end, and the driving part is connected to the lifting part and is used for driving the lifting part to stretch out and draw back. The pulley part comprises at least one first pulley and a connecting rope, the first pulley is rotatably connected to the fixed end of the driving part around the axis of the first pulley, and the connecting rope is connected to the sliding part and the extension end of the driving part and passes through the first pulley. The first pulley and the connecting rope drive the sliding part to move relative to the lifting part through stretching and retracting of the driving part. The technical problem that due to the fact that the number of driving parts or the number of stages of telescopic arms is increased, the dead weight of the lifting device is increased can be solved.
本发明公开了一种混合驱动升降装置,包括:升降组件和驱动组件,升降组件包括升降件和滑动件,升降件可伸缩,滑动件沿升降件的轴向可滑动连接于升降件,驱动组件包括驱动件和滑轮件,驱动件具有固定端和伸长端,驱动件连接于升降件,用于驱动升降件伸缩,滑轮件包括至少一个第一滑轮和连接绳,第一滑轮绕自身轴线可转动连接于驱动件的固定端,连接绳分别连接于滑动件和驱动件的伸长端并绕过第一滑轮,通过驱动件的伸缩以使得第一滑轮和连接绳驱动滑动件相对升降件移动。本发明能解决升降装置由于增加驱动件的数量或伸缩臂的级数,从而导致装置的自重增加的技术问题。
