Reversed V-shaped mast hoisting system with flexible guide rails

The utility model discloses a reversed V-shaped mast hoisting system with flexible guide rails. The reversed V-shaped mast hoisting system comprises a top operation platform, a reversed V-shaped mast, an amplitude changing tackle pulley and winding machines, and further comprises a guide arm, a guide crossbeam and two flexible guide rails, wherein the guide arm is fixed at the top of the reversed V-shaped mast; a plurality of flexible guide rail connection points are arranged symmetrically on the left side and the right side of the guide arm; the guide crossbeam is fixed on a load; mechanisms connected with the flexible guide rails are arranged at the two ends of the guide crossbeam; the two flexible guide rails are parallel; pre-tightening force adjusting devices are arranged at the tail ends of the flexible guide rails. The application method of the hoisting system is that fixed lifting lugs and guide rope fixing devices are connected together through steel wire ropes, pretension devices, and the like to achieve designed pre-tightening force, and form the flexible guide rails; the lifting tackle on the reversed V-shaped mast with the guide arm is utilized for bearing; the load is lifted along the flexible guide rails, so as to realize hoisting operation; meanwhile, the load is influenced by wind pressure function is considered; when horizontal displacement is conducted, the gravity center is diverged; the horizontal force caused by the gravity is calculated according to the moment of force balance principle.
