The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of wind-driven generator group wind-wheel inner big parts lifting appliance, reduce the hoisting cost of the inner big parts of wind-driven generator group wind-wheel.
The technical scheme that its technical matters that solves the utility model adopts is: the inner big parts lifting appliance of a kind of wind-driven generator group wind-wheel, be used to lift by crane inner each parts of installing of wheel hub of wind wheel, the inner big parts lifting appliance of described wind-driven generator group wind-wheel has guiding screw pole, play boatswain chair, shackle, rigging, steel rope, first pulley, second pulley, winch, the root of described guiding screw pole has the root screw thread, described guiding screw pole has reached boatswain chair by the root screw thread with the parts that need lifting and has been connected, described boatswain chair captiveed joint with shackle, described rigging one end is connected with shackle, the described rigging other end hangs on the suspension hook of first pulley, described steel rope one end is fixed on the wheel hub top of wind wheel when lifting by crane, the described steel rope other end passes first pulley successively, second pulley is to winch.
Further, described second pulley is fixedly mounted on the wheel hub inside face top of wind wheel, and described winch is installed on the wheel hub web of wheel hub of wind wheel.
Further, the top of described guiding screw pole has screw top, and the spiral shell footpath of screw top is less than the spiral shell footpath of root screw thread, and the screw top top of described guiding screw pole has taper guiding point.
The beneficial effects of the utility model are: be fixed on the wheel hub top of wind wheel during the lifting of steel rope one end, the steel rope other end passes first pulley, second pulley successively to winch, and guiding screw pole has reached boatswain chair by the root screw thread with the parts that need lifting and has been connected.When for example the parts that need lift by crane are blade, guiding screw pole has reached boatswain chair by the root screw thread with the blade root of blade and has been connected, move by winch, the scrolling steel rope makes rigging be pulled up, and has further reached boatswain chair by shackle guiding screw pole is upwards sling, and then the blade that is threaded with guiding screw pole is upwards sling, make things convenient for the replacing of blade, make blade realize vertically lifting, can significantly reduce hoisting cost, reduce the lifting accident.In like manner can lift by crane the big parts of other wind-driven generator group wind-wheel in-to-ins, realize the quick replacing of the inner big parts of wind-driven generator group wind-wheel, the fast quick-recovery of blower fan is normally moved.
