The gas turbine wheel disc hoisting device is characterized in that the gas turbine wheel disc hoisting device comprises a chassis, a pull rod pin, a nut and an expansion head, the chassis is installed above a wheel disc of a gas turbine, the expansion head is located in a connecting hole of the wheel disc, the pull rod pin is inserted into the expansion head, and a pull rod threaded head of the pull rod pin penetrates through the connecting hole of the chassis; the pull rod threaded head is sleeved with a nut in a matched mode. Lifting of the wheel disc is achieved through friction force, safety and reliability are achieved, and the problem of wheel disc lifting without lifting point positions is perfectly solved.
本发明的目的在于提供一种燃气轮机轮盘吊装装置及吊装方法,其特征是:包括底盘、拉杆销、螺母、涨头,燃气轮机的轮盘上方安装底盘,涨头位于轮盘的连接孔中,拉杆销插入涨头中,且拉杆销的拉杆螺纹头穿过底盘的连接孔,拉杆螺纹头外部配合套有螺母,底盘上安装有吊环。本发明通过摩擦力实现轮盘的吊装,安全可靠,完美解决了无吊装点位的轮盘吊装的问题。
