Steel structure engineering component rotating device

The utility model discloses a rotating device for a steel structure engineering component. The rotating device comprises a fixed plate, the device is assembled and fixed to a proper moving assembly through a fixing plate, then when work needs to be carried out, an electro-hydraulic telescopic rod can be started to drive an extension rod to move, then a toothed rod is driven to move under connection of a connecting piece, meanwhile, the toothed rod drives an adjusting gear to rotate under cooperation of teeth, and the working efficiency is improved. Under connection of a threaded sleeve, two connecting rods can be driven to move oppositely, then clamping plates can be driven to clamp an object to be moved, at the moment, the connecting rods are limited through second limiting grooves, and at the moment, a servo motor can be started to drive a rotating gear to rotate; the rotating rod can be driven to rotate under the cooperation of the transmission gear, then the whole rotating block can be driven to rotate, a
