Power generator rotor vertical maintenance auxiliary support device

Abstract

The present invention discloses a power generator rotor vertical maintenance auxiliary support device which comprises a bottom plate. The bottom of the bottom plate is symmetrically provided with four universal wheels. The top of the bottom plate is provided with two clamp plates, a bayonet is formed between the two clamp plates, and a rotation rod is matched in the bayonet. Bolts are matched between the rotation rod and the clamping plates. The top of the rotation rod is provided with an embedded hole. A roller bearing is matched in the embedded hole. A circumferential direction rotation rod is matched above the rotation rod. The lower end of the circumferential direction rotation rod is matched with an insertion rod which is matched in the roller bearing. A rotor axis positioning device is matched on the circumferential direction rotation rod. According to the device, the rotor of a power generator can be positioned well, the circumferential direction rotation of the power generator rotor can be realized at the same time, the maintenance is convenient, the power generator rotor can be vertically placed to conveniently inspect the internal part, the missed maintenance is avoided, and the times of maintenance are shortened.

Description

technical field [0001] The invention relates to an auxiliary supporting device for vertical maintenance of a generator rotor. Background technique [0002] The rotor in the generator is an important part for winding the coil. When the rotor is damaged, the entire generator set cannot continue to be used. When performing rotor maintenance, most of the existing methods are to place the rotor on the ground, and then maintenance personnel The rotor needs to be rotated in a timely manner to facilitate coil winding or other maintenance work. The rotor is large in size and heavy in mass, so manual rotation can easily lead to excessive rotation or cause safety accidents. At the same time, the rotor in the prior art only It can be placed horizontally, and it is not convenient to check the inside of the rotor, which is likely to cause accidents of incomplete maintenance, and it needs to be disassembled and repaired later, which is troublesome. [0003] Based on the above problems, it...
