The invention relates to a large platform lifting device, in particular to a counterweight-free lifting device of a large lifting platform. The lifting device structurally comprises at least four supporting stand columns, wherein first fixed pulleys are arranged at the tops of the supporting stand columns, a traction rope is wound around each first fixed pulley, one end of each traction rope is connected with a peripheral side face of the lifting platform, while the other end of the traction rope is connected with a buffering movable pulley mechanism arranged below the first fixed pulley, a lifting hook is arranged on a movable pulley of the buffering movable pulley mechanism, and the lifting hook is connected with a speed reducer through a steel wire rope. The counterweight-free lifting device of the large lifting platform provided by the invention can enable a small-power motor to drive the traction ropes to lift the large lifting platform without designing a counterweight, so that the mounting cost and the maintenance cost are greatly reduced.
本发明涉及一种大型平台升降装置,特别涉及一种大型升降平台的无配重升降装置。其结构包括至少四根支撑立柱,所述的支撑立柱顶部设置有第一定滑轮,所述的第一定滑轮绕有牵引绳,所述的牵引绳一端连接升降平台的四周侧面,另一端连接设置于所述第一定滑轮下方的缓冲动滑轮机构,所述的缓冲动滑轮机构的动滑轮上设置有吊钩,所述的吊钩通过钢丝绳连接减速机。本发明提供了一种大型升降平台的无配重升降装置,其无需配重设计,就可以让小功率电机带动牵引绳对大型升降平台进行起落升降,大幅减少了安装成本和维护成本。
