The invention discloses a high-altitude self-overturning pulley hook. The high-altitude self-overturning pulley hook comprises an arc-shaped hook arranged at the upper part of a hook plate (3), a pulley (8) arranged at the lower part of the hook plate (3), a guide mechanism and a pulley overturning mechanism; the guide mechanism is composed of a guide block (1) hinged to the end of a hook head and a traction rope (13) connected to the lower end of the guide block (1); and the upper end of an L-shaped connecting rod (6) is hinged to the center of the top end of the arc-shaped hook, a falling-off ring (7) is connected to the lower end of the connecting rod (6), a lifting rope (14) is pulled, and when a rope knot (15) pushes the falling-off ring (7), the falling-off ring (7) drives the connecting rod (6) to enable the arc-shaped hook to be overturned upwards to form the pulley overturning mechanism. The high-altitude self-overturning pulley hook has the advantages that the pulley hook can be hung on a high-altit
