The invention provides a tower top assembly of a tower crane, and relates to the technical field of engineering machinery. The tower top assembly of the tower crane comprises a fixed base, two first rotating supports are fixedly connected to one side of the top of the fixed base, a main supporting frame is rotatably connected between the two first rotating supports, and a connecting plate is fixedly connected to the top of the center of the main supporting frame; a mounting mechanism is fixedly connected to the center of the top of the main supporting frame; an adjusting mechanism corresponding to the main supporting frame is mounted in the center of the end, away from the two first rotating supports, of the top of the fixed base; and a plurality of reinforcing rods are fixedly connected to the peripheral side of the main supporting frame. The main supporting frame can be freely adjusted by designing the adjusting mechanism, a tightening mechanism, a balance end guide mechanism and a hoisting end guide mechanism which are simple, so that the tower top of the whole tower crane is better balanced, meanwhile, the firmness of connection between the balance end and the hoisting end canbe improved by additionally arranging a steel wire rope, and the tower top assembly is worthy of being widely popularized.

    本发明提供一种塔机塔顶组件,涉及工程机械技术领域。该种塔机塔顶组件,包括固定底座,所述固定底座顶部的一侧固定连接有两个第一转动支架,两个所述第一转动支架之间转动连接有主支撑架,所述主支撑架中心的顶部固定连接有连接板;所述主支撑架顶部的中心固定连接有安装机构,所述固定底座的顶部远离两个第一转动支架一端的中心安装有与主支撑架相对应的调整机构,所守护主支撑架的周侧均固定连接有多个加固杆。通过设计简单的调整机构、收紧机构以及平衡端导向机构和起重端导向机构,即可对主支撑架进行自由调节,以便使整个塔机塔顶实现更好的平衡,同时也可通过增加钢丝绳来提高平衡端和起重端之间连接的牢固性,值得大力推广。
