The wind turbine tower is usually provided with a lifter, a safety lock and other devices, and is also provided with a driving steel wire rope and a safety steel wire rope. In order to improve the stability of the elevator during lifting movement, a guide steel wire rope is also required to be installed in the tower drum of the fan, so that the elevator can lift and move along the guide steel wire rope. The shape of a fan tower cylinder is conical, namely the diameter of the lower end of the tower cylinder is larger than that of the upper end of the tower cylinder, and the diameter of the tower cylinder is gradually reduced from bottom to top, so that a certain taper is formed on the inner wall of the tower cylinder. In traditional fan tower section of thick bamboo facility, a platform is all installed at every fixed height, sets up the car hole that supplies the car to pass through on the platform, and direction wire rope passes through from the car downthehole row of platform, and the lift reciprocates along direction wire rope. The structure of the platform is optimally designed, so that the upper and lower alignment of the car hole can be realized, the guide steel wire rope can be in a vertical state, and the elevator can also move up and down on a vertical path.
In some simple and easy fan tower section of thick bamboo, perhaps consider that the cost to wind-powered electricity generation facility is controlled, can cancel the platform in the tower section of thick bamboo among the prior art, owing to lacked the platform facility, the lift car is no longer current from any car downthehole, and under this kind of condition, direction wire rope direct mount is on the inner wall of tower section of thick bamboo. Because the inner wall of the tower barrel has certain taper, the guide steel wire rope arranged on the inner wall of the wind turbine tower barrel also has certain inclination, and a specific form of the guide of the inclined steel wire rope is formed. The aforementioned guiding forms place higher guiding requirements on the tower hoist than guiding wires arranged in a vertical state. On the other hand, the escape window is usually arranged at the bottom of the car in the existing tower elevator, and when a danger occurs, an operator can escape from the bottom of the car to the nearest platform and transfer the escape window, however, in the fan sleeve which cancels the platform in the tower, the escape operator can not escape from the escape window at the bottom to the platform and needs to optimally design the escape mode of the elevator according to actual needs.
