Embodiment

[0021] This embodiment provides a hydraulic side shifting device for a large gas turbine generator, such as figure 1 , 2 , 3, considering the structural design of the generator itself, a foot bracket 1 suitable for the side movement of the whole machine is arranged between the generator foot plate and the foundation bottom plate. The seat is connected and fixed by the tension screw 2, and fixed firmly by the positioning key 3. As a part of the generator, the foot bracket 1 is used as a transitional support for the connection between the generator and the foundation during installation and operation, and is used to realize the connection between the generator and the foundation. support structure;

[0022] When the generator needs to slide laterally, use a jack to jack up the generator and the foot support 1 to the required height through the jacking position reserved on the foot support 1;

[0023] The side shift bracket 4 is assembled and spliced ​​by multi-section brackets...

Abstract

The invention discloses a large-scale gas turbine generator hydraulic side shifting device which is characterized in that the large-scale gas turbine generator hydraulic side shifting device comprises a footing support and a side shifting support, the footing support serves as a transition supporting body, the footing support is provided with a plurality of reserved jacking positions, and the footing support is jacked up through a jack; at least two sets of side moving supports are arranged, sliding heavy rails are arranged on the side moving supports, and sliding blocks and pushing machines for pushing the sliding blocks are installed on the sliding heavy rails in a sliding mode. When the generator needs to slide laterally, the jack jacks up the generator and the footing bracket to the required height; the sidesway support is placed below the footing support, the sliding block moves to the position below the footing support, the footing support is supported by the sliding block, and the pushing machine pushes the sliding block to drive the generator and the footing support to laterally slide. The problems of lateral movement overhauling and lateral movement resetting of the single-shaft-system gas turbine generator are solved, lateral sliding of the whole generator is achieved by combining the overall structural design of the generator, field mounting and dismounting of the unit are facilitated, and the convenience of follow-up unit operation and maintenance is improved.

Description

technical field [0001] The application relates to a large-scale gas turbine generator hydraulic side shifting device, which is used to realize the lateral sliding of the complete generator, and belongs to the technical field of generator operation and maintenance supporting machinery and hydraulic equipment. Background technique [0002] Due to the domestic demand for clean energy, gas turbine combined cycle power plants are one of the directions for the construction of new power plants that meet environmental protection requirements. The single-shaft arrangement in the combined cycle unit is to connect the gas turbine, steam turbine and generator in series on one shaft, and the generator is arranged between the steam turbine and the gas turbine. Usually, the generator is connected to the top. Considering the investment and economic indicators, there is no large-tonnage crane on site, so the complete generator cannot be lifted and moved. After the first installation, when t...
