Abstract

The invention discloses a gas turbine supporting device. The gas turbine supporting device comprises at least one pair of main supports and at least one pair of auxiliary supports. The main supports are used for absorption compensation during radial thermal expansion of a gas turbine and return positioning during radial cold shrinkage of the gas turbine, and each main support comprises a main supporting seat fixedly connected with a unit of the gas turbine, a main supporting body and a main mounting part fixedly connected with the gas turbine; The auxiliary supports are used for absorption compensation during axial thermal expansion of the gas turbine and return positioning during axial cold shrinkage of the gas turbine, each auxiliary support comprises an auxiliary supporting seat fixedlyconnected with the unit of the gas turbine and an auxiliary mounting part, one end of each auxiliary mounting part is rotationally connected with the corresponding auxiliary supporting seat through an auxiliary rotating shaft, the other ends of the auxiliary mounting parts are rotationally connected with the gas turbine through fixed shafts, the auxiliary rotating shafts are parallel to the central axes of the fixed shafts, and the auxiliary rotating shafts and the fixed shafts are perpendicular to the central axis of the gas turbine. The gas turbine supporting device is high in adjusting precision during thermal expansion and cold shrinkage of the gas turbine.

Description

technical field [0001] The invention relates to the technical field of gas turbines, in particular to a support device for a gas turbine. Background technique [0002] In a traditional complete set powered by a gas turbine, the shaft diameter of the gas turbine is used to carry the weight of the complete gas turbine unit. The shaft diameter of the gas turbine is installed on the common base of the unit. The gas turbine rotates at high speed in a high-temperature application environment, and thermal expansion and centrifugal vibration occur in the axial and radial directions, causing the shaft diameter of the gas turbine to deviate from the original position of the axis. The connection between the shaft diameter of the gas turbine and other parts of the unit deviates, and the shaft diameter of the gas turbine undergoes stress deformation, which affects the normal operation of the overall equipment of the gas turbine. [0003] Chinese patent application CN2861495Y discloses a...
