Abstract

The invention discloses axial and lateral bidirectional simple centering equipment of a gas turbine and relates to the field of gas turbine centering, and the problems that the existing centering equipment is low in adjustment precision and time and labor are wasted in the centering process are solved. The axial and lateral bidirectional simple centering equipment of the gas turbine comprises an axial centering device and four lateral centering devices, wherein the four lateral centering devices are located on the periphery of the axial centering device; the axial centering device comprises end plates, a first bottom plate, supporting plates, a pull rod, a connecting plate and nuts; and each lateral centering device comprises a second bottom plate, a vertical plate, rib plates and a bolt.The axial and lateral bidirectional simple centering equipment is applied to a gas turbine installation process and is in precise centering with other load equipment.

Description

technical field [0001] The invention relates to the field of gas turbine centering, in particular to an axial and lateral bidirectional simple centering device for a gas turbine. Background technique [0002] After the overhaul of the domestic 30MW gas-driven compressor unit and other types of gas turbines, the gas turbine needs to be re-installed, and the re-installation process requires precise alignment of the gas turbine and the compressor or other load equipment. Since the gas turbine is re-installed and the anchor bolts of other load equipment such as the compressor are not loose, the position of the gas turbine is generally adjusted for centering; due to the large size and mass of the gas turbine, the horizontal position movement is inconvenient and the movement accuracy is low. The alignment devices used for gas turbines and load equipment are tools such as guide chains and jacks. Since the guide chains and jacks have no installation position, they are inconvenient t...
