[0030] Combine the following Figure 1 to Figure 7 A detailed description of the use steps of a wind power tower that is easy to maintain in this article: In the initial state, the power box 16 is far away from the load-bearing box 64 and is located at the upper limit position, the large gear 69 and the small gear 71 are not meshed, and the moving plate 28 and the power plate 74 are both in the right limit position.

The friction block 89 generates centrifugal force during the rotation, which in turn generates a tendency to approach the inner wall of the deceleration chamber 93, thereby driving the ring plate 90 Relative to the rotating trend of the turntable 11, when the wind is below the limit, the rotation speed of the shaft 18 is below the limit. At this time, the centrifugal force generated by the friction block 89 is less than the torsion force of the torsion spring 94, the annular plate 90 remains stationary, and the friction block 89 Will not conflict with the inner wall of the deceleration chamber 93, and when the wind is too strong, the rotation speed of the shaft 18 exceeds the limit speed, the centrifugal force generated by the friction block 89 is greater than the torsion force of the torsion spring 94, and the friction block 89 and the inner wall of the deceleration chamber 93 conflict And friction, and then the turntable 11 is decelerated by the friction force, and then the rotating shaft 18 is decelerated.

Through the threaded connection, the screw 40 is driven down and the power box 16 is driven down to the lower limit position. At this time, the large gear 69 meshes with the small gear 71, and the staff stands above the station board 49. The maintenance tools are also placed above the station board 49, the hydraulic machine 39 is started and the hydraulic arm 38 is extended, and then the power board 74 is moved to the left, and then the pinion gear 66 is moved to the left to the power bevel gear 45 through the driven shaft 67. When meshing, the large gear 69 and the small gear 71 always keep meshing. At the same time, the power plate 74 drives the moving plate 28 to move to the left through the connecting plate 35, and then drives the bevel gear 44 to move to the left through the transmission shaft 29 and interacts with the power bevel gear 45 and transmission bevel gear 43 Disengaged, the motor 15 continues to be started at this time, the power bevel gear 45 drives the pinion bevel gear 66 to rotate through the gear mesh, the large gear 69 is driven to rotate through the driven shaft 67, the electric pinion 71 is rotated through the gear mesh, and the transmission is driven through the connecting shaft 73 The bevel gear 58 rotates, and the driven bevel gear 57 rotates through gear meshing. The fixed shaft 59 drives the front and rear driving sprockets 60 to rotate counterclockwise synchronously, and then the chain 97 drives the lifting platform 53 to rise, thereby driving the staff and maintenance tools Ascending, during the ascending process, the stability is ensured by the expansion spring 46 and the compression spring 52, which reduces the shaking of the lifting platform 53 and causing the staff to stand unsteady, until the lifting platform 53 rises to the upper limit position and stops, at which time the staff performs maintenance.
[0033] The beneficial effects of the present invention are: the present invention is simple in structure and convenient to operate. When the wind speed is greater than the limited wind speed, the power generation device can be decelerated by the clamping device to play a protective role. When maintenance is required, the power generation tower can be lowered by the lifting device The height of the lifting platform is driven by the synchronous chain lifting mechanism. There is a shock absorption device in the lifting platform, which can make people more stable on the lifting platform.
