The invention belongs to the field of tower cranes, and particularly relates to an intelligent unmanned tower crane jacking device which comprises a jacking sleeve, an outer sleeve, an inner rod, a reset spring, a guide wheel, a guide sleeve, a limiting rod, a tower body section frame, a clamping block A, a jacking mechanism and an electric push rod. Wherein the top sleeve is nested outside a plurality of tower body section frames which are sequentially stacked and connected together through high-strength bolts, two layers of outer sleeves are mounted on the inner side of the top sleeve, and eight symmetrical outer sleeves are arranged in each layer; the transmission connection cooperation between the telescopic structures where any two opposite guide wheels are located can effectively prevent the rotary base from shaking relative to the tower body section frame in the lifting process due to the fact that the balance arm and the cargo boom are unbalanced. The transmission connection cooperation between the telescopic structures where any two opposite guide wheels are located ensures that the tower body section frame with the inaccurate or deformed appearance cannot be stuck with the guide wheels in the jacking process.
本发明属于塔机领域,尤其涉及一种智能无人塔机顶升装置,它包括通过高强度螺栓安装于回转座下端的顶套、外套、内杆、复位弹簧、导向轮、导套、限位杆、塔身节架、卡块A、顶升机构、电动推杆,其中顶套嵌套于通过高强度螺栓依次堆叠连接在一起的若干塔身节架外,顶套内侧安装有两层外套,每层中具有对称的八个外套;任意相对两个导向轮所在伸缩结构之间的传动连接配合会有效阻止回转座在抬升过程中相对于塔身节架因平衡臂与起重臂不平衡而产生晃动,同时,任意相对两个导向轮所在伸缩结构之间的传动连接配合在顶升过程中保证出产外形不精确或变形的塔身节架不会与导向轮发生卡死。
