The invention discloses a counterweight-free self-balancing movable type self-climbing high-altitude crane which comprises an upper structure system, a supporting system and a track system, the structural system comprises a cargo boom and hoisting trolleys, the cargo boom comprises space trusses composed of a plurality of standard knots, and each space truss is provided with a corresponding hoisting trolley; the supporting system comprises a stand column composed of a plurality of standard knots, a bottom column installed at the bottom of the stand column and a self-climbing system. Each stand column corresponds to one self-climbing system, the top of each self-climbing system is connected with the cargo boom, and each bottom column is correspondingly installed on the track system. The track system is laid on the structural beams and the structural columns. According to the invention, high-altitude horizontal free movement can be realized, in-situ hoisting is carried out on a component, and the working radius is reduced. The problem that an existing tower crane needs a balance weight is solved through simultaneous hoisting on the two sides. Along with gradual increase of construction floors, the crane only needs to self-climb for 1-2 floors, and the safety problem caused by the too high height of the tower crane is solved. The problem that the cost is increased due to the fact that the tower crane model number is increased due to the fact that components in an existing fabricated building are too heavy is solved, and the safety performance of high-altitude hoisting is also improved.
本发明公开了一种无配重自平衡移动式自爬升高空起重机,包括上部结构系统、支撑系统及轨道系统;所述上述结构系统包括起重臂及吊装小车,起重臂包括若干标准节组成的空间桁架,每个空间桁架均设置相应的吊装小车;所述支撑系统包括若干个标准节组成的立柱、安装在立柱底部的底柱以及自爬升系统;每个立柱对应一套自爬升系统,每套自爬升系统顶部与起重臂连接,每个底柱分别对应安装在轨道系统上;所述轨道系统铺设于结构梁和结构柱上。本发明能够实现高空水平自由移动,对构件进行原位吊装,减小了工作半径。两侧同时起吊解决了现有塔吊需要配重的问题。随着施工楼层逐步增加,本发明的起重机只需要自爬升1‑2层,解决了塔吊高度过高带来的安全问题。本发明解决了现有装配式建筑中的构件过重带来的塔吊型号增大而导致的成本增加的问题,也提高了高空吊装的安全性能。
