The invention relates to a torsion installation conversion structure of a tower crane, and belongs to the technical field of tower cranes. Comprising an upper main chord, a lower main chord, an upper cover plate, a lower cover plate and an inner rib plate, the upper main chord and the lower main chord are welded on a conversion foundation through the inner rib plate, a through hole I for the upper main chord to pass through is formed in the upper cover plate, a through hole II for the lower main chord to pass through is formed in the lower cover plate, the lower cover plate is welded to the bottom of the upper main chord, and the upper cover plate is welded to the top of the lower main chord. The tower crane has the beneficial effects that a functional structure capable of realizing torsional installation of the tower crane is initiatively provided, the adaptability of the tower crane to complex working conditions is expanded, the problem that an existing tower crane cannot be installed in a torsional mode due to interference with a building is solved, and the tower crane has higher space adaptability.

    本发明涉及一种塔式起重机扭转安装转换结构,属于塔式起重机技术领域。包括上主弦、下主弦、上盖板、下盖板和内筋板,上主弦和下主弦通过内筋板焊接在转换基础上,上盖板上设有供上主弦通过的通孔Ⅰ,下盖板上设有供下主弦通过的通孔Ⅱ,上主弦的底部焊接下盖板,下主弦的顶部焊接上盖板。本发明的有益效果是:首创性的提出可实现塔式起重机可扭转安装的功能结构,拓展了塔式起重机复杂工况适应能力,克服现有塔式起重机因与建筑物干涉无法扭转安装的问题,使塔式起重机具有更大的空间适应性。
