The invention discloses a superlift device with a cantilever crane posture control function and a use method thereof. A cantilever crane head angle detection device used for obtaining the angle ATop of the head of a cantilever crane relative to the horizontal plane and a cantilever crane root angle detection device used for obtaining the angle ARoot of the root of the cantilever crane relative to the horizontal plane are arranged at the upper end of the cantilever crane. According to the method, the phenomenon of deflection of the boom in the boom extending process of the crane can be effectively solved or relieved, the deflection of the root and the head of the boom is detected, the boom is adjusted in real time in cooperation with a steel wire rope of the hoisting mechanism, the boom is kept in a linear state, deflection of the boom is reduced to the maximum extent, and the boom can be adjusted in real time. Especially for the condition that the telescopic boom is long, the effect is more remarkable, the anti-bending performance of the boom can be improved, and the stability, safety and ultrahigh hoisting performance of the crane are truly improved.
本发明公开了一种具有臂架姿态控制的超起装置及其使用方法,其在臂架的上端设有用于获取臂架头部相对水平面角度ATop的臂架头部角度检测装置和用于获取臂架根部相对水平面角度ARoot的臂架根部角度检测装置,配合卷扬机构控制放绳量实现ARoot和ATop的一致性,本发明能够有效的解决或者缓解起重机在伸臂过程中的臂架挠曲现象的产生,通过实施检测臂架根部与头部的挠曲度,配合卷扬机构的钢丝绳实时调节臂架,使其保持直线状态,最大减小其挠曲,尤其是针对伸缩臂较长的情况,其效果更为显著,本发明能够提高臂架抗挠曲性能,真正提高起重机的稳定性、安全性以及超高吊装性能。
