Special tool for hoisting hydro-generator rotor magnetic pole

Abstract

A special tool for hoisting a hydro-generator rotor magnetic pole is provided with a magnetic pole upper end sling, a magnetic pole lower end sling, the rotor magnetic pole, two first bolts, two second bolts, four cushion plates, two rubber rings and four rubber pads. Each cushion plate is provided with a panel, two inner side edge plates and two limiting plates. Each panel and the corresponding two inner side edge plates form a cavity matched with the end angles of the rotor magnetic pole; the positions of the four end angles of the rotor magnetic pole are each covered with the corresponding cushion plate; and each rubber ring is wound around the four cushion plates to connect the two rubber rings, the four cushion plates and the rotor magnetic pole together. According to the specific connection structure, each rubber ring is wound around two limiting grooves in each cushion plate and corresponding to the rubber ring, and is further wound around a pair of elastic pieces corresponding to the rubber ring to press down the upwarping ends of the pair of elastic pieces. The special tool for hoisting the hydro-generator rotor magnetic pole can make the rotor magnetic pole hoisted and placed flat easily, it is avoided that the rotor magnetic pole collides with peripheral devices and is damaged, and the disassembling and assembling efficiency of the generator rotor magnetic pole is improved.

Description

technical field [0001] The invention relates to a special tool for hoisting, in particular to a special tool for hoisting the rotor magnetic pole of a hydraulic generator. Background technique [0002] If the rotor poles need to be lifted out of the generator wind tunnel for inspection and maintenance, because the weight of the poles is heavy, it is not easy to hoist and lay flat, and it is easy to bump into the surrounding equipment, causing damage, and the disassembly efficiency of the generator rotor poles is low . [0003] The inventor has retrieved the following relevant patent documents: CN206156568U discloses a special tool for hoisting the rotor magnetic pole of a hydroelectric generator, which has a magnetic pole upper end sling, a magnetic pole lower end sling, and a rotor magnetic pole. The magnetic pole upper end sling has a first web , the first rib located on the front end of the first web and perpendicular to the first web, the steel pipe fixed on the top of ...
