The invention relates to a self-balancing large-operation-space lifting device. The device comprises a base component, fixing components, a parallel four-rod frame component, a bearing frame, drivingcomponents and a balancing box, wherein the base component comprises a fixed base, a movable base, a balance box base, a first hinged support and a second hinged support; the fixing components are symmetrically arranged on the two sides of the front portion of the fixed base, the parallel four-bar frame component is arranged on the inner sides of the fixing components and is connected with the fixing components through the driving components, and the bottom of the parallel four-bar frame component is hinged to the first hinged support and the second hinged support; the bearing frame is arranged on the inner side of the top of the parallel four-bar frame component, and the balance box is installed on the balance box base. The gravity center moves backwards along with descending of a liftedobject, self-balancing of the machine body can be achieved during movement by adjusting the balance weight in the balance box, the characteristic of large operation space is achieved, and compared with a traditional jacking mechanism, the lifting range of the lifted object can be greatly enlarged.
本发明涉及一种自平衡式大作业空间升降装置,包括基座组件、固定组件、平行四杆框架组件、承载框、驱动组件和平衡箱;所述基座组件包括固定基座、活动基座、平衡箱基座、第一铰支座和第二铰支座;所述固定组件对称设置在固定基座前部两侧,所述平行四杆框架组件设置在固定组件内侧,所述平行四杆框架组件和固定组件之间通过驱动组件连接,且所述平行四杆框架组件底部与第一铰支座和第二铰支座铰接,所述承载框设置在平行四杆框架组件顶部内侧,所述平衡箱安装在平衡箱基座上。本发明随着托举物下降而重心后移,通过调整平衡箱内配重,运动时可实现机体自平衡,而且具有大作业空间的特点,与传统顶升机构相比可大大增加托举物体的升降范围。
