The invention discloses a polaroid-based lifting appliance swing angle measuring device and system. A bridge crane comprises a cart mechanism, a trolley mechanism, a lifting rope, a lifting appliance and a lifting appliance lifting motor. The device comprises a swing frame, a box body, a second polaroid and a transmission assembly, wherein the free end of the lifting rope penetrates through the swing frame and then is connected with the lifting appliance; the box body is provided with a containing space; the second polaroid is rotatably installed in the containing space, the first side of the second polaroid is used for receiving incident linearly polarized light, the linearly polarized light is emitted from the second side of the second polaroid, and a photoelectric detector arranged on the second side of the second polaroid is used for receiving the emitted linearly polarized light; the first end of the transmission assembly is mounted on the second polaroid, and the second end of the transmission assembly is mounted on the swing frame; when the lifting appliance swings, the lifting rope connected with the lifting appliance drives the swing frame to swing, the swing frame drives the second polaroid to rotate through the transmission assembly, and the polarization direction of the rotated second polaroid changes.

    本发明公开了一种基于偏振片的吊具摆动角度测量装置及系统,该桥吊包括大车机构、小车机构、吊绳、吊具和吊具起升电机,该装置包括:摆架,其中,吊绳的自由端贯穿摆架后与吊具连接;盒体,具有容纳空间;第二偏振片,可转动地安装在容纳空间内,其中,第二偏振片的第一侧用于接收射入的线偏振光,该线偏振光从第二偏振片的第二侧射出,第二偏振片的第二侧设置的光电检测器用于接收该射出的线偏振光;传动组件,其第一端安装在第二偏振片上,其第二端安装在摆架上;当吊具摆动时,连接吊具的吊绳带动摆架摆动,摆架通过传动组件带动第二偏振片转动,其中,转动后的第二偏振片的偏振方向发生变化。
