Hereinafter, according to the present embodiment, the wind turbine according to the present embodiment may include a lifting unit 500 according to the wind turbine generator installed above the temporary frame 400. The process of installing a generator will be described in detail.

First, as shown in FIG. 17, the barge or the ship carrying the tower structure 110 on the extension 310 of the connection deck 300 provided in the foundation structure 200, and then interconnected, and moving cart Install the bogie on the rail 320 for transporting the tower structure 110 to the upper surface of the connection deck (300). That is, the tower structure 110 is to be transferred into the lower side of the temporary frame 400 installed on the connection deck 300. Subsequently, when the tower structure 110 is transferred to the lower portion of the temporary frame 400, one end of each cable 580 of the lifting means 500 is firmly fixed to the tower structure 110, respectively. At this time, the pressure cylinder 620 of the lateral load supporting means 600 is contracted so that the support plate 610 is spaced apart from the tower structure 110.

However, while each cable 580 is fixed to the tower structure 110, the pressurizing cylinders 620 of the lateral load supporting means 600 are operated respectively, so that each support plate 610 presses the outer circumferential surface of the tower structure 110. May be supported.

The first tower structure 110 transported in this process is firmly coupled to each cable 580 of the strand jack in a state located inside the temporary frame 400.

When the hydraulic cylinder 550 is operated, the piston 551 moves forward and backward to reciprocate the first anchor block 560. As the first anchor block 560 reciprocates, the first and second lifting

jaws

561 and 571 operate to pull and fix the cable 580. That is, when the first anchor block 560 moves forward by the piston 551, the first lifting jaw 561 moves forward without fixing the cable 580, and the first anchor block 560 moves on the piston ( When reversing by 551, the first lifting jaw 561 pulls the cable 580 while retracting together with the first anchor block 560 while the cable 580 is fixed. According to this operation, the second lifting jaw 571 is also operated to pull and fix the cable 580 together with the first lifting jaw 561.

As such, the tower structure 110 fixed to each cable 580 is raised by repetitive operation of each strand jack.

On the other hand, when the tower structure 110 transferred to the connecting deck 300 is moved upward by the lifting means 500, the hydraulic motor 732 of the auxiliary lifting means 700 to operate the pinion 731 and the rack The engagement of the gear 721 raises the lifting rod 720 to cause the backing plate 710 to support the bottom of the tower structure 110.

The pushing operation of the is made at the same time.

In other words, when the tower structure 110 is raised by the lifting means 500 by the lifting means 500 and the auxiliary lifting means 700 interlocked, the auxiliary lifting means 700 is also operated to support the supporting plate 710. To push up the tower structure 110 to assist in the elevation of the tower structure 110. As such, since the auxiliary lifting means 700 assists the lifting means 500, the lifting operation of the heavy tower structure 110 may be smoothly performed.

Subsequently, when the tower structure 110 rises, as shown in FIG. 19, the next tower structure 110, that is, the second tower structure 110, is transferred to the lower portion of the temporary frame 400 by the above-described process. Let's do it. Then, the lifting means 500 is operated to lower the first tower structure 110 to couple the first tower structure 110 and the second tower structure 110. In this process, when the first tower structure 110 and the second tower structure 110 are combined, each cable 580 is released from the first tower structure 110, and the lateral load supporting means 600 is operated backward. The support plate 610 is spaced apart from the first tower structure 110.

Subsequently, when the first tower structure 110 and the second tower structure 110 are combined, an upper portion such as a hub, a blade, and a nussel is formed on the top of the first tower structure 110 using a crane as shown in FIG. 20. Join the structure 120. In this case, the upper structure 120 may be coupled to the first tower structure 110 after the third tower structure is coupled.

On the other hand, as the respective tower structures 110 are coupled, the wind load acting on the mutually coupled tower structures 110 is increased. In particular, the wind load due to the rapid gust has a great influence on the tower structure 110, so that the lateral load supporting means 600 is operated so that the support plate 610 presses the tower structure 110 to support the lateral load.

Subsequently, the above-described process is repeated to sequentially combine the remaining tower structures 110 to complete the tower, and fix the lowest tower structure 110 to the foundation structure 200.

When the coupling of the tower structures 110 is completed, the temporary frame 400 is removed as shown in FIG. 21.

As described above, the tower structures 110 constituting the wind power generator 100 are coupled to each other in a vertical direction by the temporary frame 400, so that the operations of combining the tower structures 110 may be more stably and easily performed. And, the lifting means 500 made of strand jacks are respectively installed on the upper portion of the temporary frame 400, the lifting means 500 is a smooth lifting operation without friction loss.
