Description

Novel motor rotor drawing-through device Technical Field The utility model relates to the technical field of motor penetration rotors, in particular to a novel motor penetration rotor device. Background ‌ Drawing the rotor ‌ means that the air inside the generator rotor is drawn from the proximal section of the rotor by rotational centrifugal force, causing the generator rotor to lose balance, causing drive train oscillations and mechanical damage. The utility model discloses a motor rotor drawing-through device, which comprises a support rail, a sliding structure, two groups of sliding structures, two groups of rotating shaft clamping structures and two hanging lifting structures, wherein the sliding structures are arranged at two ends of the support rail, the two groups of rotating shaft clamping structures are respectively arranged on the two groups of sliding structures and are used for fixing rotating shafts at two ends of a motor rotor, the hanging lifting structures are arranged between the sliding structures and the rotating shaft clamping structures and are used for lifting or descending the rotating shaft clamping structures, and the motor rotor drawing-through device is characterized in that the motor is placed below the support rail when a large-sized motor rotor is required to be drawn out, the two groups of rotating shaft clamping structures are respectively clamped and fixed at shaft ends at two ends of the rotor, and then the hanging structure is used for controlling the rotating shaft clamping structures to enable the whole rotor to be lifted upwards relatively, so that a worker can directly pull the rotor out of a motor housing, the rotor can be moved out from the motor housing, the rotor can be moved out conveniently and quickly and easily by the worker can be moved into the housing by means of lifting force after the motor housing, and the motor rotor drawing-through device can be more conveniently and safely pulled out by the operator.
