一种风管吊装装置

Abstract

本实用新型公开了一种风管吊装装置，其属于安装工程技术领域，包括吊梁结构、钩挂结构和吊装带，至少两个吊梁结构关于风管主体对称设置，吊梁结构上开设有吊接孔和连接孔，连接孔与法兰孔对应设置，连接孔和对应的法兰孔之间能够通过锁紧螺栓连接，以将吊梁结构可拆卸地固定于风管主体的端部；每个吊梁结构两端的吊接孔各设置有一个钩挂结构，钩挂结构能够钩挂并锁定于吊接孔；对应每个钩挂结构设置有一个吊装带，多个吊装带的自由端汇聚于共同吊点。综上所述，该风管吊装装置通过吊梁结构多点平衡吊挂的设计，实现了风管吊装过程的平衡与稳定；同时，避免了吊装带被风管主体的法兰切割磨损的风险，增强了吊装作业的安全性。
