The invention provides a steel chimney dismantling method which comprises the following steps: S1, dismantling the top of a chimney: a worker stands on an annular platform at the top of the chimney, and cuts a hoisting hole and a hoisting hole at the top of a chimney wall; the hoisting holes and the hoisting holes are symmetrically formed in the chimney along the circumference, totally four hoisting holes and eight hoisting holes are formed, a crane lifting hook extends to the position over the chimney, and the crane lifting hook and the hoisting holes are connected through a sling; compared with the prior art, the problem that the distance between the annular platform and the inner wall of the chimney is large can be solved through outward movement of the extending platform, and the device is suitable for segmented cutting and dismantling of chimneys of different sizes. The stability of the bottom of the annular platform during rotary cutting is kept through the stabilizing assembly, the problems of overall instability, gravity deviation and the like of the annular platform due to extension of the extending platform are solved, and the efficiency of dismantling the chimney is improved.
本发明提供一种钢烟囱的拆除方法，所述拆除方法包括以下步骤：S1、烟囱顶部的拆除：人员站在烟囱顶部的环形平台上，切割烟囱壁顶部的吊装孔和起吊孔；起吊孔和吊装孔在烟囱内部沿圆周对称布置，共计四个吊装孔和八个起吊孔，吊车吊钩伸至烟囱正上方，使用吊索具连接吊车吊钩与起吊孔；吊车微起钩受力，调整并确认吊钩位于烟囱中心位置，吊索具受力均匀，相对于现有技术，通过伸出平台的向外移动可以解决环形平台与烟囱内壁相距较远的问题，适用于不同大小的烟囱分段切割拆除，通过稳定组件保持环形平台底部在进行旋转切割时的稳定性，不会因为伸出平台的延伸而导致环形平台整体不稳定，重力偏移等问题，提高拆除烟囱的效率。
