Description
Technical Field
[0001] The present invention relates to the technical field of motor rotor maintenance, and in particular to generator rotor maintenance equipment. Background Art
[0002] A generator is a mechanical device that converts mechanical energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery. It converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy. The rotor is the core component of the generator.
[0003] After a generator has been used for a period of time, its internal rotor needs to be inspected and maintained to extend its service life. During the inspection and maintenance of the rotor, the rotating shafts at both ends need to be fixed and supported so that they are suspended in the air for easy disassembly by the operator. However, some complex parts are fixed on each end face of the rotor, and the disassembly work is also cumbersome.
[0004] However, common maintenance equipment has a relatively simple structure and is mostly fixed on a desktop. It cannot be rotated to adjust the maintenance direction, which requires the operator to disassemble the rotor in a circular manner according to the various end faces of the rotor, resulting in low maintenance efficiency. In addition, common maintenance equipment is not convenient for adjusting the working height according to the operator's height, which requires the operator to look up or down to work. Working for a long time can easily cause damage to the cervical spine, and the practicality is insufficient. Therefore, we propose a generator rotor maintenance equipment. Summary of the Invention
