The invention belongs to the field of tower cranes, and particularly relates to an automatic jacking tower crane structure which comprises a jacking frame fixedly installed at the lower end of a tower crane rotary table, two hydraulic cylinders A, guide wheels, a tower section, an upward jacking mechanism and the like. The tail ends of the two hydraulic cylinders A are provided with push plates which are used for horizontally pulling the tower section which is hoisted to the platform through the hoisting trolley into the jacking frame; two hydraulic cylinders A can hoist a crane carriage to a tower section on a platform through a push plate to automatically pull the tower section into a jacking frame, and after the tower section is pulled into the jacking frame, an electric push rod B pushes a corresponding locking block to be inserted into a locking groove in a corresponding fixing block A to fasten and lock the tower section; and the reciprocating swing of the hydraulic cylinder B in the jacking process of the rotary table is completed by the electric push rod A, so that unmanned operation to a certain degree is realized, and effective technical support is provided for the subsequent intelligent unmanned operation of the tower crane.

    本发明属于塔吊领域,尤其涉及一种自动顶升塔机结构,它包括固装于塔机回转台下端的顶升架、液压缸A、导轮、塔节和上顶机构等,其中嵌套于塔节的顶升架上安装有两个对称分布于平台两侧且水平伸缩的液压缸A,两个液压缸A末端安装有将通过起重小车吊至平台的塔节水平牵拉入顶升架内的推板;本发明中的两个液压缸A通过推板可以将起重小车吊装至平台上的塔节自动牵拉进顶升架内,并且在塔节牵拉进顶升架内后通过电动推杆B推动相应锁块插入相应固定块A上的锁槽将塔节进行紧固锁定,同时,液压缸B在其对回转台的顶升过程中的往复摆动由电动推杆A完成,实现了一定程度的无人化,为后续塔机的智能化无人化操作提供有效的技术支撑。
