The invention discloses a water turbine top cover turnover device which comprises a protection unit, and the protection unit comprises a shell, a pair of locking rods arranged in the shell, a multi-stage hydraulic telescopic cylinder arranged on one side of the shell, a lantern ring arranged at the end of the multi-stage hydraulic telescopic cylinder and a driving block arranged in the lantern ring. And the overturning unit comprises a bearing rod arranged in the shell and a push block arranged below the driving block. The hydraulic turbine overturning device has the beneficial effects that the hydraulic turbine overturning process is more stable through hydraulic driving, the problem that a rope is prone to shaking and breaking in the hoisting or unloading process is solved, collision or deformation is not prone to occurring in the hoisting or unloading process, and the hydraulic turbine overturning device is safer and more reliable.
本发明公开了一种水轮机顶盖翻转装置,包括防护单元,包括壳体、设置于壳体内部的一对锁止杆、设置于壳体一侧的多级液压伸缩缸、设置于多级液压伸缩缸端部的套环,以及设置于套环内部的驱动块;翻转单元,包括设置于壳体内部的承接杆,以及设置于驱动块下方的推块。本发明的有益效果为通过液压驱动使水轮机翻转过程更加平稳,避免了绳索吊装或吊卸过程中容易晃动、崩断的问题,使得吊装或吊卸过程不易发生磕碰或变形、更加安全可靠。
