The invention discloses a detachable latticed column lifting device which comprises first lifting components, second lifting components, connecting rods and driving mechanisms driving the connecting rods to rotate. One end of each first lifting component is hinged to one end of the corresponding second lifting component, the other ends of the first lifting components and the other ends of the second lifting components are connected through the connecting rods, one end of each connecting rod is connected with the corresponding first lifting components through threads, and the other ends of the connecting rods are hinged to the second lifting components. When the connecting rods rotate forwardly, the other ends of the first lifting components are close to the other ends of the second lifting components. When the connecting rods rotate backwards, the other ends of the first lifting components are away from the other ends of the second lifting components. According to the connecting rods which rotate forwardly, the other ends of the first lifting components and the other ends of the second lifting components are close to and clamp the top of a latticed column, and the prefabricated latticed column is lengthened. In the process of latticed column lifting, the position of the latticed column can be conveniently adjusted, in the lifting process, the shaking amplitude is small, and security coefficients are high. The detachable latticed column lifting device can be repeatedly used, and the construction cost is saved.
