Method and device for replacing a blade (13) in wind turbines that comprises two elements, one upper (1) and the other lower (2) that work together to raise and/or lower the blade (13) of a wind turbine. The device's upper element or “top” (1) comprises some elements (4) bolted to the bearing (3) of the wind turbine and some means of fastening (5) the blade (13), while the lower element or “ground” (2) is a structure that encompasses the wind turbine tower (8) and has at least two winches (2.5) and two deviation pulleys (2.4) to connect some cables (6) between the device elements, namely the “top” (1) and “ground” (2).
