The invention belongs to the technical field of inner jacking of tower cranes, and provides a jacking method for an inner jacking tower crane main body, the method relates to a tower crane main body, and the method comprises the following steps: step (1), a climbing unit drives an inner sleeve frame to climb upwards along a tower body at the current height, so that the inner sleeve frame is supported on the tower body after the inner sleeve frame rises to a height A; (2) after the inner sleeve frame rises, the climbing unit moves upwards by the height A and then is supported on the tower body; (3) mounting a heightened standard knot on the top of the tower body; (4) the step (1) and the step (2) are repeated, and the inner sleeve frame is lifted to the heightened standard knot; when the pre-jacking height is not reached, returning to the step (3); and when the pre-jacking height is reached, the inner sleeve frame is fixed on the tower body, and jacking is completed. The climbing height of the inner sleeve frame can be increased by mounting the heightening standard knot on the top of the tower body, so that the tower crane can climb in the tower body of the tower crane.

    本发明属于塔吊内顶升技术领域,提供了一种内顶升塔吊主体的顶升方法,该方法涉及一种塔吊主体,所述方法包括如下步骤:步骤(1):爬升单元驱动内套架沿当前高度的塔身往上爬升,使内套架上升高度A后,将内套架支撑在塔身上;步骤(2):在内套架升高后,爬升单元上移高度A,然后支撑在塔身上;步骤(3):在塔身的顶部安装加高标准节;步骤(4):重复步骤(1)和步骤(2),使内套架上升至加高标准节;当未达到预顶升高度时,返回步骤(3);当达到预顶升高度时,将内套架固定在塔身上,完成顶升。本发明可以在塔身顶部安装加高标准节来增加内套架的爬升高度,实现塔吊在自身的塔身内爬升。
