[0016] The utility model discloses a steam turbine fault detection device having the following beneficial effects.

[0017] First, by setting up a lifting mechanism, after the collar is installed at both ends of the steam turbine, the rope reel is driven to rotate by starting the motor, so that the rope reel reels the steel cable, thereby stretching the steam turbine upward, and at the same time, the rope reel is driven to rotate the rotating shaft, so that the rotating rod is rotated, and the push block connected with the external thread is driven to slide upward, so that the push block provides lifting force for both ends of the steam turbine, which plays an auxiliary lifting effect, prevents the collar and both ends of the steam turbine from falling off, ensures the safety of lifting and testing, and can lift the steam turbine, which is convenient for the staff to conduct comprehensive observation and maintenance, and at the same time increases the stability of lifting;

[0018] Secondly, by setting up a placement mechanism, the steam turbine is placed on the placement rack.
