The invention belongs to the technical field of bridge steel shell lifting construction, and particularly relates to a lifting appliance device suitable for a gravity center changing curve type steel shell, the lifting appliance device comprises a steel shell, mounting angle blocks are mounted on the peripheral surface of the top of the steel shell in a curve array manner, and the tops of the mounting angle blocks at the four corners of the top of the steel shell are in threaded connection with lower lifting rings; lower steel cables are fixedly mounted on the surface of the lower lifting ring, and lifting appliance mounting plates are fixedly mounted at the tops of the four lower steel cables. According to the lifting appliance device suitable for the gravity center changing curve type steel shell, by arranging the gravity center balance adjusting mechanism and the operating system, the gravity center position and the inclination angle of the steel shell can be measured in real time, the gravity center of the steel shell is adjusted according to data, and therefore the stability of the steel shell in the lifting process is kept. Through the device, the hoisting efficiency can be improved, the workload of workers is relieved, and the occurrence rate of hoisting accidents is reduced.
本发明属于桥梁钢壳起吊施工技术领域,尤其是一种适用于重心变化曲线型钢壳的吊具装置,包括钢壳,所述钢壳的顶部四周表面均曲线阵列安装有安装角块,所述钢壳顶部的四个边角处安装角块的顶部均螺纹连接有下吊环,所述下吊环的表面固定安装有下钢索,四个所述下钢索的顶部均固定安装有吊具安装板。该适用于重心变化曲线型钢壳的吊具装置,本发明通过设置重心平衡调节机构和操作系统,能够实时测量钢壳的重心位置以及倾斜角度,并根据数据调整钢壳的重心,从而保持钢壳在吊装过程中的稳定性。通过该装置可以提高吊装效率,减轻工人的工作负担,降低吊装事故的发生率。
