The invention relates to a self-balancing lifting device, which belongs to the technical field of mechanical balance and comprises a power source, the power source is connected with a speed reducer, and the speed reducer is provided with at least three output shafts arranged in parallel; part of the output shafts are connected with a balance screw rod, the balance screw rod and a balance nut fixed on the rack form a balance screw rod nut pair, and the other end of the balance screw rod is rotationally connected with a balanced part so that the balanced part can ascend and descend along with the balance screw rod; a damping device is arranged at the end, close to the balanced part, of the balance lead screw to apply pretension force to the balanced part. Part of the output shafts are connected with pressure-bearing lead screws, the pressure-bearing lead screws are located between the balance lead screws, the pressure-bearing lead screws and pressure-bearing nuts fixed to the rack form a pressure-bearing lead screw and nut pair, and the other ends of the pressure-bearing lead screws make contact with a piece to be balanced so as to apply pre-pressure to the piece to be balanced. The hydraulic balance cylinder can be replaced for balancing, and has the advantages of reducing power sources, simplifying equipment pipelines, saving energy and being environmentally friendly.

    本发明涉及自平衡升降装置,属于机械平衡技术领域,包括动力源,动力源连接有减速机,减速机具有至少3个呈平行设置的输出轴;部分输出轴连接有平衡丝杆,平衡丝杆与固定在机架上的平衡螺母形成平衡丝杆螺母副,平衡丝杆的另一端与被平衡件转动连接以使被平衡件跟随平衡丝杆升降;平衡丝杆靠近被平衡件的一端设有阻尼装置以对被平衡件施加预拉力;部分输出轴连接有承压丝杆,且承压丝杆位于平衡丝杆之间,承压丝杆与固定在机架上的承压螺母形成承压丝杆螺母副,承压丝杆另一端与被平衡件接触以对被平衡件施加预压力。本发明能够替代液压平衡缸进行平衡,具有减少动力源、简化设备管路、节能环保的优点。
