Problems solved by technology

[0004] The inventor found that the existing large-scale floating power generation ships try to realize the power supply of a large area, and there are multiple generator sets and auxiliary equipment on board, resulting in crowded space on board, and generally cannot leave enough separate space It is used for the pumping rotor maintenance of steam turbines on board; while the temporary lifting device is used for pumping rotor maintenance, it is necessary to install a lifting device on the floating power generation ship, which not only takes up space and increases the weight of the hull, but also needs to be designed for the stability of the lifting device on the hull , which greatly increases the cost

Embodiment 1

[0046] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 and Figure 7 As shown, Embodiment 1 of the present invention provides a floating power generation ship steam turbine generator rotor maintenance track system. The power generation ship described in this embodiment is a gas-steam combined cycle generator set, which adopts a "two-to-one" multi-shaft. The layout plan, the gas turbine and the waste heat boiler are arranged outdoors, and the steam turbine is arranged indoors. The specific schematic diagram of the first boiler 1, the second boiler 2, the steam engine room 3, the steam turbine generator 4 and the generator rotor space 5 is as follows figure 1 As shown, the turbine generator 4 is not reserved in the turbine room 3 to extract the rotor space, and the space between the first boiler 1 and the second boiler 2 is used to construct the generator extraction rotor space 5 for rotor extraction.

[0047] The maintenance rail system includes: a...

Embodiment 2

[0060] Embodiment 2 of the present invention provides a method for overhauling the rotor of a steam turbine generator of a floating power generation vessel, using the rotor overhauling track system of the steam turbine generator of a floating power generation vessel described in Embodiment 1 of the present invention, including the following processes:

[0061] When the unit is in normal operation, the first maintenance track and the second maintenance track are freely deformed with their respective main structures, and the guide steel plate on the second track is not installed at this time;

[0062] Before the generator overhauls the extraction rotor, install the guide steel plate on the second track to control the relative position of the first overhaul track and the second overhaul track, so that the overhaul hoist transitions from the first overhaul track to the second overhaul track when the rotor is extracted, and passes through the second overhaul track. The space between...

Abstract

The invention provides a floating power generation ship turbonator rotor maintenance track system and method.A track deformation joint is formed in the connecting portion of the first end of a first maintenance track and the first end of a second maintenance track, and the side, away from the second maintenance track, of the first maintenance track is fixedly connected with a steam engine room frame structure; the side, away from the first overhauling track, of the second overhauling track is fixedly connected with the track support. The rail support is arranged between the first boiler and the second boiler and at least comprises a first rod piece and a second rod piece which are parallel to each other, the first end of the first rod piece is fixedly connected with a first bracket on the first boiler steel frame, and the first end of the second rod piece is fixedly connected with a second bracket on the first boiler steel frame. The second end of the first rod piece is in sliding connection with a third bracket on a second boiler steel frame, and the second end of the second rod piece is in sliding connection with a fourth bracket on the second boiler steel frame; the sizes of a steam engine room and a turbine-boiler room are optimized, the size of a ship body is reduced, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of floating power generation ships, in particular to a track system and method for overhauling a steam turbine generator rotor of a floating power generation ship. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] There are usually two ways to extract the rotor of the turbo-generator. One is to reserve the rotor extraction space in the main workshop, and the rotor extraction work is completed by running the main workshop during rotor maintenance; the other is to not reserve the rotor extraction space in the main workshop. The size of the main workshop is reduced, but the space outside the workshop is sufficient, and the rotor extraction can be completed by a temporary lifting device during rotor maintenance. [0004] The inventor found that the existing large-scale floating power gene...
