And the bracket 2 is slidably positioned on the rack frame 11 in the axial direction of the column 13, and the gear 41 is engaged with the rack 12, so that the bracket 2, the blade hanger 300 and the blade 200 can be kept to be lifted synchronously by the driving of the driving device 42. In addition, in the process of synchronously lifting the bracket 2, the blade lifting tool 300 and the blade 200, the winch 3 can control the retraction of the rope 31, so that the rope 31 has horizontal pulling force back to the boom or the tower 500, and the problems that wind force, the pulling force of the rope 31 on the boom or the portal 400 and collision between the blade 200 and the boom or the tower 500 are easy to occur can be avoided.

That is, the wind turbine 10 provided by the present disclosure can prevent the blade 200 from colliding with the boom or the tower 500, thereby avoiding the occurrence of a safety accident.

In addition, the posture of the blade 200 can be timely adjusted through the retraction of the rope 31 on the winch 3, so that the risk of collision of the blade 200 can be further avoided, and the alignment of the flange on the blade 200 and the cabin flange can be more convenient and rapid through adjusting the posture of the blade 200, so that the fixing of the blade 200 can be conveniently realized.

In this way, the connection strength of the first support plate 111 and the second support plate 112 can be increased by the plurality of connection plates 113. In addition, the connecting plate 113 in the middle is stressed and concentrated, and the structural strength of the connecting plate 113 in the middle can be increased by setting the thickness of the connecting plate 113 in the middle to be larger, so that the connecting plate is more stable in bearing force.

Optionally, the driving device 42 has a slide 421 thereon, and the slide 421 is slidably inserted into the bracket 2 in a direction perpendicular to the axis of the cylinder 13. The adjuster 43 includes a first wedge 431 and a second wedge 432, the first wedge 431 is located on the bracket 2, a slope of the second wedge 432 contacts with a slope of the first wedge 431, and the second wedge 432 is sandwiched between the first wedge 431 and a side of the slide 421, the second wedge 432 is configured to move along the slope of the first wedge 431 to drive the driving device 42 to move in a direction perpendicular to the axis of the cylinder 13.

For example, when the wrench shaft sleeve 5 rotates forward, the two second wedges 432 can be moved in the opposite direction along the axial direction of the adjusting rod 6, and the slide 421 is pressed to the right under the limit of the first wedge 431, so that the distance between the gear 41 and the rack 12 can be reduced. When the wrench shaft sleeve 5 is reversed, the two second inclined wedges 432 can be made to move in opposite directions along the axial direction of the adjusting rod 6, the distance between the slide plate 421 and the first inclined wedges 431 can be increased, and therefore the extrusion slide plate 421 can be made to move left by external force, and the distance between the gear 41 and the rack 12 can be increased.

In the present embodiment, the actual dimensions and pitches of the bracket 2, the slide plate 421, the gear 41, and the rack gear 12 are first measured by reality. The spacing of the two second wedges 432 is then adjusted by the bushing 5. Next, the slide plate 421 and the two second wedges 432 are arranged on the first plate body 221 so that a good engagement distance between the gear 41 and the rack gear 12 is achieved. Finally, the pressing plate 25 is fixed to the first plate 221 by bolts, so that the second wedge 432 and the slide 421 are clamped.
