一种大跨度弧形钢结构吊装装置

Abstract

本实用新型公开了一种大跨度弧形钢结构吊装装置，涉及建筑施工设备技术领域，包括吊环和两个第一钢丝绳，还包括角度检测组件和角度调节组件，角度检测组件连接于吊环与两个第一钢丝绳之间，角度调节组件包括两个配重筒，两个配重筒分别对应连接于两个第一钢丝绳的下端，配重筒的下端固定连接有第二钢丝绳，第二钢丝绳的下端固定有夹持构件。本实用新型通过配重筒配合双向水泵和输水软管的设置，吊运弧形钢结构段时，利用角度检测仪对吊运块的倾斜角度进行检测，并配合双向水泵对两个配重筒中的水量进行对应调节，以调节吊运块的倾斜角度，从而使得弧形钢结构段调整至水平或者安装所需的倾斜角度，使得吊运作业更加方便可靠。
