The invention discloses a convex-lens-based double-lifting double-sling bridge crane swing angle detection device and method. The swing angle detection device is applied to a double-sling bridge crane. The double-sling bridge crane comprises a cart support, a driving device, a trolley, a pair of motors, a pair of slings and a pair of swing angle detection devices, wherein each sling is connected with the corresponding motor through a lifting rope; each swing angle detection device comprises a pair of light rods, a pair of iron rods, a pair of annular assemblies, a pair of connecting pieces, a pair of convex lenses, a pair of photoresistor detection circuits and a signal processing device; a plurality of light source generators are installed in each annular assembly; each annular assembly swings, so that laser emitted by the light source generators penetrates through the annular assemblies, is converged through the corresponding convex lenses and irradiates the corresponding photoresistor detection circuits; and the photoresistor detection circuits are used for converting received optical signals into electric signals and transmitting the electric signals to the signal processing device for processing, so that the swing angles of the corresponding lifting ropes are obtained.
