Problems solved by technology

[0004] The inventors have found that due to the large size of the steam turbine, bridge cranes are used to lift the rotor of the steam turbine when overhauling it. However, due to the different specifications of the steam turbine, the size of the rotor of the steam turbine is also different. The lifting equipment used is not the same, which leads to the fact that the same lifting equipment cannot lift steam turbine rotors of different sizes. At the same time, the current

Abstract

The invention provides auxiliary lifting equipment for maintenance of a steam turbine rotating part and a using method thereof. According to the auxiliary lifting equipment for the maintenance of thesteam turbine rotating part and the using method thereof, a longitudinal space required for maintenance of suspended steam turbine parts is greatly reduced, the environmental adaptability is greatly enhanced, mutual approaching or departing and up-down position changing and adjusting can be conducted, the same equipment can quickly fix and hoist steam turbine components with different sizes and models, the maintenance efficiency is improved, the movable and inclined plane lifting design mode is adopted, the whole equipment is moved to the bottom of a large part, then the large part is hoistedin the inclined plane pushing mode, and therefore, the part can be disassembled and assembled on site for maintenance, and the maintenance cost of the steam turbine is greatly saved.

Description

technical field [0001] The disclosure relates to the technical field of steam turbine inspection and maintenance, in particular to an auxiliary lifting device for inspection and maintenance of rotating parts of a steam turbine and a usage method thereof. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The steam turbine, also called the steam turbine engine, is a rotary steam power device. The high-temperature and high-pressure steam passes through the fixed nozzle and becomes an accelerated air flow, and then sprays onto the blades, so that the rotor equipped with blade rows rotates and works externally. The steam turbine is a modern The main equipment of thermal power plants is also used in metallurgical industry, chemical industry and ship power plant. [0004] The inventors have found that due to the large size of the steam turbine, b...
