The rotary heavy crane comprises a fixed sleeve, a rotary assembly and a construction platform, the fixed sleeve is installed at the top of the construction platform, the rotary assembly is installed on the inner wall of the fixed sleeve, and a first fixed circular ring is installed on the outer wall of the fixed sleeve; a plurality of first threaded holes are formed in the top of the first fixing ring, and bolts are installed on the inner walls of the first threaded holes. Through the arrangement of the fixing sleeve, the first fixing ring, the first threaded hole, the bolt, the limiting groove, the rotation assembly, the second fixing ring, the third fixing ring and the second threaded hole, the stability of the crane during working is improved, friction of the rotation assembly is reduced, and the service life is prolonged; through the arrangement of the first motor, the first gear, the second gear and the fixing bin, the first motor drives the second gear to rotate, the second gear drives the first gear to rotate, and then the rotation angle of the rotation assembly is conveniently adjusted.

    本发明公开了一种海上施工平台的回转式重型起重机,包括固定套筒、回转组件和施工平台,所述施工平台的顶部安装有固定套筒,所述固定套筒的内壁安装有回转组件,所述固定套筒的外壁安装有第一固定圆环,所述第一固定圆环的顶部开设有若干个第一螺纹孔,所述第一螺纹孔的内壁安装有螺栓。本发明通过固定套筒、第一固定圆环、第一螺纹孔、螺栓、限制槽、回转组件、第二固定圆环、第三固定圆环和第二螺纹孔的设置,有利于提高起重机工作时的稳定性,减少回转组件的摩擦,提高使用寿命,通过第一电机、第一齿轮、第二齿轮和固定仓的设置,第一电机带动第二齿轮旋转,第二齿轮带动第一齿轮旋转,进而便于调节回转组件的转动角度。
