The invention discloses a multi-angle adjustable large antenna attitude conversion device, which comprises an attitude conversion frame and a lifting appliance, an antenna sub-array is placed on the attitude conversion frame, the lifting appliance is connected with the antenna sub-array, and the inclination angle of the antenna sub-array is adjusted through the attitude conversion frame. The lifting appliance is vertically lifted through a lifting rope; the method does not need to control the conversion attitude of the antenna sub-array in a manual rope pulling mode, greatly eliminates the hidden danger of high-altitude operation of personnel, adjusts different angle ranges for different array planes, directly enters a large-scale antenna array plane for assembly after a specific angle is fixedly set on the ground, is high in installation angle precision, reduces the assembly error, and improves the assembly efficiency. The method has the characteristics of high consistency and good safety.
本发明公开一种多角度调节的大型天线姿态转换装置,包括姿态转换架和吊具,天线子阵放置在所述姿态转换架上,所述吊具与所述天线子阵连接,通过所述姿态转换架调节所述天线子阵摆放的倾斜角度,并通过吊绳对所述吊具进行垂直起吊;本发明无需采用人工拉绳索方式控制天线子阵转换姿态,极大消除了人员高空作业隐患,针对不同阵面调节不同角度范围,且特定角度在地面已经固定设置后,直接进入大型天线阵面上装配,安装角度精度高,减少了装配误差,具有一致性高、安全性好的特点。
