The invention belongs to the technical field of hoisting processes, and provides a generator end cover single-crane single-hook method turnover process which comprises the steps that a crane hook is used for hanging a hoisting steel wire rope, the hoisting steel wire rope comprises a main rigging and an auxiliary rigging, the main rigging comprises four first steel wire ropes with the same length, and an auxiliary lock comprises two second steel wire ropes; a chain block is hung on each steel wire rope; the two first steel wire ropes are connected with the two lifting lugs on the top face of the end cover correspondingly; driving to enable one end of the end cover to serve as a fulcrum and the other end to turn to a first state, and checking the stress conditions of the fulcrum, the lifting lug and the hoisting steel wire rope; the crane continues to act, and the other end is overturned to a second state; the crane continues to act, and the other end is overturned to a third state; the two chain blocks are connected with the other two lifting lugs on the top face of the end cover, and when the lifting hook and the gravity center of the end cover are located on the same straight line, the other two first steel wire ropes replace the chain blocks to be connected with the lifting lugs, so that the end cover is lifted through the four first steel wire ropes.
本发明属于吊装工艺技术领域,提供了一种发电机端罩单行车单钩法翻身工艺,包括,利用行车吊钩挂设吊装钢丝绳,所述吊装钢丝绳包括主索具和辅助索具,所述主索具包括四根长度相同的第一钢丝绳,所述辅助锁具包括两根第二钢丝绳,且每根钢丝绳上挂设倒链;将两根第一钢丝绳分别与端罩顶面的两只吊耳连接;行车动作,以使端罩一端为支点,另一端翻转至第一状态,检查支点、吊耳和吊装钢丝绳是受力情况;行车继续动作,另一端翻转至第二状态;行车继续动作,另一端翻转至第三状态;将两根倒链与端罩顶面另外两只吊耳进行连接,当吊钩与端罩重心在一条直线上,将另外两根第一钢丝绳替换倒链连接吊耳,以使端罩通过四根第一钢丝绳吊起。
