Abstract

The invention relates to centering devices, in particular to a gas turbine axial and lateral simple centering device. The gas turbine axial and lateral simple centering device comprises an axial centering device and lateral centering devices and is characterized in that the axial centering device comprises a base, a connecting plate, a pull rod and nuts, the pull rod is mounted on the base and connected with the two symmetrical nuts, the connecting plate is located at the end of the pull rod, and the connecting plate is fixed to the small underframe crossbeam of a gas turbine, and the base ismounted on the large underframe of the gas turbine; each lateral centering device comprises a mounting seat and a bolt which are connected in a threaded manner, and the mounting seat is fixed at the corresponding corner of the large underframe of the gas turbine. The gas turbine axial and lateral simple centering device has the advantages that centering between the gas turbine and loading equipment driven by the gas turbine during the remounting of the maintained gas turbine can be achieved, the device can be directly and conveniently mounted on the large underframe of the gas turbine, centering can be achieved only by adjusting the adjusting nuts, and the device is convenient to operate, simple in structure, safe and reliable, and stable to operate.

Description

Technical field: [0001] The invention relates to a centering device, in particular to a simple axial and lateral two-way centering device for a gas turbine. Background technique: [0002] After the overhaul of domestic 30MW gas driven compressor units and other types of gas turbines, the gas turbines need to be reassembled, and the reassembly process requires precise alignment of the gas turbines and compressors or other load equipment. Since the gas turbine is reinstalled, the anchor bolts of the compressor and other load equipment are not loose, so the alignment generally adjusts the position of the gas turbine; due to the large size and mass of the gas turbine, it is inconvenient to move the horizontal position and the movement accuracy is low. In the case of centering tools, it is necessary to use tools such as guide chains and jacks to move the gas turbine. The guide chains and jacks have no installation positions, which are inconvenient to use, adjust the accuracy, and...
