The invention discloses an automatic jigger axis measuring device which comprises a main monitoring machine and a throw sensor group. The main monitoring machine is connected with a convergence router through a network cable, the convergence router is connected with a key phase displacement sensor and the throw sensor group in a wireless communication mode and the key phase displacement sensor and the throw sensor group are both installed on a machine set axis system. The throw sensor group comprises a first throw sensor, a second throw sensor and a third throw sensor which are the same in structure. The invention further discloses a measuring method of the automatic jigger axis measuring device. The wireless sensor network technology is adopted in the automatic jigger axis measuring device and the measuring method of the automatic jigger axis measuring device, the wireless communication mode is used for replacing a wired connecting mode, therefore, the measuring precision is high, complex wire arrangement is not needed, electromagnetic interference is lowered, installation is simple and convenient and meanwhile, good expansibility is achieved.
Description
technical field [0001] The invention belongs to the technical field of automatic barring axis measuring equipment, and in particular relates to an automatic barring axis measuring device, and also relates to a method for measuring the barring axis by using the measuring device. Background technique [0002] The condition of the axis of the hydro-generator unit has a direct impact on the stability of the unit operation and the normal work of the guide bearing. If the condition of the axis of the unit is not good, it will cause excessive vibration and overheating of the bearing during the operation of the unit. Therefore, when the unit is installed or overhauled, the axis of the unit must be carefully measured and adjusted. [0003] The traditional automatic barring axis measurement method is mainly to measure the barring swing of the unit, that is, to use the barring method to slowly rotate the assembled shafts, and use measuring instruments (micrometers or displacement sens...
