The invention discloses an automatic lifting device for a wind shield of a generator of a large water-turbine generator set. The automatic lifting device comprises the wind shield, a lifting device, a load detection device, an annular hanger rail and a control system. The lifting device is controlled by the control system to move, signals sent by the load detection device are received in a centralized mode through the control system in the moving process, loads of all points are calculated, control signals are output at the same time, the driving device is controlled to enable all the lifting points to synchronously lift or descend the wind shield integrally, and the effect of automatically lifting the wind shield is achieved. The problems that in the prior art, in the overhauling process, dismounting and transferring processes are troublesome, and potential safety hazards exist are solved.
本发明公开了一种大型水轮发电机组发电机挡风板自动升降装置,包括,挡风板、提升装置、载荷检测装置、环形吊轨、控制系统。本发明由控制系统控制提升装置运动,并在运动过程中通过控制系统集中接收载荷检测装置发出的信号,并计算各点载荷,同时输出控制信号,控制驱动装置使各吊点同步对挡风板进行整体提升或下降,实现自动提升挡风板的效果。解决现有技术中存在的检修过程中拆卸、转运过程中较为麻烦,且有安全隐患的问题。
