Abstract

The invention provides a step-by-step small-stroke automatic jacking device which takes a power device as a driving core and comprises a shell, a first reversing assembly, a second reversing assembly and a linear module, wherein the first reversing assembly, the second reversing assembly and the linear module are packaged in the shell. In operation, one of the two reversing assemblies is in a locked state to restrict movement of the reversing assembly in a specific direction of the lifting inner column, and the other reversing assembly is in an unlocked state to allow the reversing assembly to freely pass through the lifting inner column. The linear module and the two reversing assemblies working alternately are matched with the lifting inner column with the lifting ladder rail, so that efficient, stable and controllable small-stroke step-by-step lifting is realized. Meanwhile, the construction platform frame body is connected with the shell of the power device through the outer sleeved high column, and the building structure is connected with the lifting inner column through the bracket assembly, so that the construction platform is driven to climb. By adopting the step-by-step small-stroke automatic jacking device, the construction efficiency can be increased, the number of constructors is reduced, and the construction platform, the templates, the peripheral protection, the construction equipment and the like with larger weight can be borne.
