A wind power hoisting system according to claim 8, characterized in that: An operating area (4) is provided on one side of the crane (1), a switch group is provided on one side of the operating area (4), a storage battery (6) is installed on one side of the top of the second disc (32), an output end of the storage battery (6) is electrically connected to an input end of the switch group, and the output end of the switch group is electrically connected to the input ends of the first motor (33), the first electric push rod (36), the second electric push rod (310), the second motor (51) and the third electric push rod (56), respectively.

10. A wind power hoisting method according to the wind power hoisting system according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Preparation for hoisting. A worker is located in the operation area (4) and operates the crane (1) so that the second hook (9) at the bottom of the mounting seat (10) is located inside the connecting frame (7). Then, under the power of the crane (1), the first disc (31) and the second disc (32) are raised and the first hook (54) is connected to the wind turbine. The speed at which the crane (1) moves upward when hoisting the wind turbine is 0.1-0.9 m / s. S2, the second hook (9) is limited. When the wind power equipment is at the installation position, and the screws and screw holes of the wind power equipment need to be aligned, the switch group only needs to be pressed to control the push rod end of the second electric push rod (310) to extend, and the push rod end pushes the limit plate (35) to fit the inner side of the mounting seat (10); S3, horizontal hoisting adjustment of the wind power equipment, press the switch group again to control the output shaft of the first motor (33) to rotate, so that the output shaft drives the input shaft of the gear reducer (34) to rotate, so that the output shaft of the gear reducer (34) drives the first disc (31) to rotate, and at this time the first disc (31) drives the two first hooks (54) at the bottom to rotate. When the screws and screw holes of the wind power equipment are aligned, the output shaft of the first motor (33) stops rotating, and at the same time, the switch group is pressed to control the push rod end of the first electric push rod (36) to extend, so that the limit rod (37) passes through the inner side of the through hole (38) and is inserted into the inner side of the limit groove (313). At this time, the first disc (31) drives the first hook (54) and the wind power equipment to stop rotating; S4, vertical hoisting adjustment of the wind power equipment, the staff presses the switch group to control the output shaft of any second motor (51) to rotate, when the output shaft of the second motor (51) rotates clockwise, the wire rope (53) is released, the release speed of the wire rope (53) is 1-10cm / s, according to the vertical offset position of the wind power equipment, the wire rope (53) on the corresponding side is controlled, so that the wind power equipment hoisted by the first hook (54) at the lower end of the wire rope (53) is in a vertical state.
