Zusammenfassung: | The invention discloses a stacking lifting mechanism based on constant tension of air cylinders. The stacking lifting mechanism comprises two supports which are bilaterally symmetrical, wherein a stacking lifting frame which can be moved vertically along the two supports is disposed between the two supports; through the two supports, a tensioning chain and the stacking lifting frame can be connected to tensioning air cylinders by tensioning chain wheels; both of the tensioning air cylinders are connected to a first electromagnetic on-off valve, a pressure regulating overflow valve, a check valve and a second electromagnetic on-off valve by air pipes; transmission chains which are meshed with lifting rack rings sleeve the two supports; the bottom end of each of the two lifting rack rings ismeshed with a lifting chain wheel; space between the two lifting chain wheels sleeves a roller which is fixed on the two supports; and the roller is connected to a driving source which makes the roller roll.
