Description

Technical Field

A wind turbine generally consists of components such as a wind wheel, a generator, a direction regulator, a tower, a speed limit safety mechanism, and an energy storage device.

[0003] When installing a wind turbine, the wind turbine is usually hoisted. When hoisting the wind turbine, the wind turbine often swings due to the high hoisting height, which affects the hoisting of the wind turbine.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. By providing the traction mechanism and the tensioning mechanism, when hoisting the wind turbine, the bottom of the wind turbine is traction-treated by the traction mechanism, so as to facilitate the balance assistance for the hoisting of the wind turbine. During this period, when the wind turbine is being tractioned, the traction of the traction mechanism can be tensioned by the clamping member, so as to improve the traction effect of the traction mechanism on the wind turbine, and prevent the traction mechanism from being slack when the traction mechanism tractiones the wind turbine, resulting in the disappearance of the pulling force of the traction mechanism on the wind turbine, thus affecting the balance assistance for the hoisting of the wind turbine.

[0017] 2. By providing the pushing mechanism, when the traction of the traction mechanism is tensioned by the clamping member, the connecting plate will move upward under the action of the traction mechanism and the clamping member. At this time, the push rod will move upward with the upward movement of the connecting plate, so that the push rod drives the push plate to jack up, and then the push plate pushes the support frame to slide to one side, so that the two pressing rollers squeeze the rope, so as to improve the tightness of the rope for tractioning the wind turbine, and thus improve the traction effect of the rope on the wind turbine, and prevent the rope from being slack when the rope tractiones the wind turbine, thus affecting the balance assistance for the wind turbine.

[0018] 3. By providing the downward pressing mechanism, when the wind turbine is tractioned by the traction mechanism, the connecting frame will rotate with the rotation of the rotating rod. Since the shape of the connecting frame is U-shaped, therefore, with the rotation of the connecting frame, the connecting shaft will drive the pressing plate to move up and down reciprocally under the action of the connecting frame and the connecting sleeve. When the pressing plate moves downward, at this time, the pressing plate squeezes the support plate. At this time, the support plate will move upward under the action of the pressure, so that the traction mechanism moves downward, and thus it is convenient to improve the tightness of the rope for tractioning the wind turbine, so as to improve the traction effect of the rope on the wind turbine.
