Description

Double-shaft-extension generator side-shifting system and generator Technical Field The utility model relates to the field of maintenance of large-scale generator sets, in particular to a side shifting system of a double-shaft extension generator and the generator. Background At present, the QFW-85-2P generator is applied to the market of European gas turbine waste heat boilers, matched with a Hangzhou gas turbine, and has the external dimensions (length, width and height) of 9255mm, 3440mm and 4730 and the total weight of 130T. And a traveling crane without corresponding tonnage in a factory building is used, and a 600t automobile crane is used as a hoisting machine in assembly, so that the whole factory building is hoisted in a direct hoisting mode. As shown in figure 1, the motor is of a double-shaft extending structure, namely, the main shaft extending end of the generator 1 is connected with the gas turbine, and the secondary shaft extending end of the generator is connected with the gear box and the high-pressure cylinder to form a bidirectional shafting. When the motor is overhauled, the space at two ends is limited, and the generator rotor cannot be pulled out from the inside of the stator at the original position 3. When in field maintenance, the whole machine needs to be moved to the maintenance platform 2 for maintenance. The motor is limited by the weight and the volume as the motor is limited by the other large-sized double-shaft stretching generators, is greatly influenced by the insufficient tonnage of a crane and the operation implementation space when the whole motor moves, has higher implementation cost, cannot meet the use requirement, and is highly required to be provided with a device and a method for carrying out the whole lifting and side-shifting functions on the double-shaft stretching generators, so that the whole maintenance requirement of the double-shaft stretching motor is met, and the field maintenance cost of a user is reduced. Disclosure of utility model The utility model aims to provide a side shifting system of a double-shaft-extension generator and the generator, which can effectively solve the problems of insufficient space and inconvenient movement of an existing double-shaft-extension-structure motor during on-site maintenance, safely and conveniently complete the whole side shifting of the motor, improve the maintenance efficiency and reduce the maintenance cost.
