[0002] Gas turbines applied to large surface ships require a support system that can not only withstand various loads brought by the normal operation of the gas turbine, but also withstand the impact load brought by the hull. The operating conditions of marine gas turbines are complex, and the support system needs to be reasonably absorbed. and transmission of various stresses, it is difficult to achieve a simple structure while ensuring long-term effective work
[0003] In the prior art, a three-section support method is generally used to support the front casing, middle casing and power turbine casing of the gas turbine respectively. When this support method is used for assembly, the support device cannot bear excessive impact loads and is prone to over-positioning Assembling, specifically, when the gas turbine pitches and expands due to heat, it will not only generate assembly stress with the support device, but also cause structural damage to the installed support device

The invention discloses a supporting structure of a gas turbine, and belongs to the field of gas turbine tests. The supporting structure is used for supporting the gas turbine; a front casing, a middle casing, a power turbine casing and an exhaust device sequentially extend from one end of the gas turbine to the other end of the gas turbine; and the supporting structure of the gas turbine comprises a base (1), a front casing supporting assembly (2), a middle casing supporting assembly (3) and a power turbine casing supporting assembly (4), wherein the front casing supporting assembly (2), the middle casing supporting assembly (3) and the power turbine casing supporting assembly (4) are arranged on the base (1). By arranging supports on the front section, the middle section and the rear section of the gas turbine, the supporting structure can bear various loads generated during operation of the gas turbine; meanwhile, an adjusting device is arranged, so that various problems during installation of the gas turbine are solved; and the supporting structure has the advantages of being simple in structure and convenient to install.
