The invention relates to a method for replacing a gearbox on a wind driven generator tower. The method comprises the following steps that S1, a cabin top cover is hoisted; s2, a pipeline is dismantled; s3, a first shackle and a first sling are installed, the top end of the first sling is connected with a chain block, the top end of the chain block is connected with a crane hook, a second shackle and a second sling are installed, and the top end of the second sling is connected with the crane hook; s4, lifting a lifting hook of the crane; s5, if the position of the lifting hook of the crane deviates, the chain block is adjusted, and the lifting hook of the crane is adjusted to be right above the gravity center of the gear box; s6, the lifting hook of the crane continues to lift the hook, if deviation exists, the step S5 is repeated, and if deviation does not exist, lifting force is applied to the dead weight value of the gearbox; and S7, the hydraulic jack is used for pushing the gearbox to break away from the wind driven generator spindle. The invention has the following beneficial effects: the dismounting is convenient; and the gearbox can be independently hoisted and taken down, and the main shaft of the wind driven generator does not need to be hoisted together, so that construction steps are reduced, construction time is shortened, and construction cost is reduced.
本发明涉及一种风力发电机塔上更换齿轮箱的方法,包括以下步骤:S1、吊装机舱顶盖;S2、拆除管路管线;S3、安装第一卸扣和第一吊带,第一吊带顶端连接手拉葫芦,手拉葫芦顶端与吊车吊钩连接,安装第二卸扣和第二吊带,第二吊带顶端与吊车吊钩连接;S4、吊车吊钩起钩;S5、若吊车吊钩位置发生偏移,则调节手拉葫芦,将吊车吊钩调整回齿轮箱重心正上方;S6、吊车吊钩继续起钩,若有偏移则重复步骤S5,若无偏移,则施加起吊力量至齿轮箱自重数值;S7、使用液压千斤顶顶推齿轮箱脱离风力发电机主轴。本发明的有益效果是:拆卸方便;并且可以单独吊装取下齿轮箱,不需要将风力发电机主轴也一并吊装,减少施工步骤,缩短施工时间,降低施工成本。
