Description

Technical Field

[0001] The utility model relates to the technical field of generator maintenance, in particular to a generator maintenance tool. Background Art

[0002] A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery, and 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. Generators are widely used in industrial and agricultural production, national defense, science and technology, and daily life. Generators come in many forms, but their working principles are all based on the laws of electromagnetic induction and electromagnetic force. Therefore, the general principle of its construction is to use appropriate magnetic and conductive materials to form magnetic circuits and circuits that are electromagnetically inductive with each other to generate electromagnetic power and achieve the purpose of energy conversion. Generators are usually composed of stators, rotors, end covers, bearings and other components.

[0003] When inspecting a generator, in order to more clearly inspect the inside of the generator, the staff needs to disassemble the generator and expose the internal parts so that the staff can inspect the internal parts of the generator. The generator usually needs to be turned during the disassembly process, and common generators are usually large and heavy. It is difficult to move the generator by manpower alone, or it takes a lot of effort to move it, resulting in low overall efficiency of the inspection work.

[0004] In order to solve the above problems existing in the maintenance of generators, under the existing technology, for the maintenance of generators, the staff often places the generator on a maintenance device for repairing the generator, and arranges components on the maintenance device for facilitating the adjustment of the engine position and the maintenance of the generator, thereby completing the maintenance of the generator. However, the generator maintenance device under the prior art has certain shortcomings and deficiencies, such as the patent with application number 202222882094.2 and publication number CN219404192U. The basic principle of the generator maintenance device in the patent is: it includes a rotating table, the generator is placed on the top surface of the rotating table, to disassemble the generator, the stepper motor is driven by the PLC controller, and the driving shaft of the stepper motor drives the rotating table to rotate, thereby turning the generator for disassembly, and the generator is leak-tested by using a halogen leak detector, and the disassembled generator parts are placed in the cleaning tank, and the driving motor is started by the PLC controller. The driving shaft of the driving motor drives the connecting column, the cleaning column, the rotating column and the cleaning cloth to rotate. When the cleaning column rotates, the cleaning cloth will scratch the parts of the generator. When the cleaning column, the connecting column and the rotating column rotate, the friction of the cleaning column will cause the rotating column to rotate. By rotating the cleaning column, the rotating column and the cleaning cloth, the dust and oil on the generator parts are simply cleaned.

[0005] However, since the rotating table used to place the generator is directly set on the stepper motor and the shaft of the stepper motor, the pressure generated by the generator's own weight and gravity will directly act on the shaft and the stepper motor. As the number of times the generator is placed accumulates, the excessive pressure for a long time can easily cause damage to the stepper motor and the shaft, resulting in a short service life of the components used to adjust the engine's orientation, and these components need to be replaced more frequently. Utility Model Content

The stepper motor is used to indirectly drive the inspection disk to rotate by the transmission of mechanical kinetic energy between gears, so that the pressure brought by the generator does not directly act on the stepper motor and the rotating shaft, effectively avoiding the damage of the stepper motor and the rotating shaft caused by the pressure brought by the engine, which is convenient for extending the service life of the stepper motor and the rotating shaft, and reducing the replacement frequency of components such as the stepper motor and the rotating shaft used to adjust the position of the engine.

[0009] Option 2 is the preferred option of the basic option. An ultrasonic cleaning box for cleaning the generator parts is provided on the top of the base.

At the same time, by setting the slide grooves and limit grooves, the number of partitions 1 can be adjusted through the slide grooves according to the size of the parts, and the number of partitions 2 placed on the partition 1 can be adjusted through the limit grooves and grooves, thereby adjusting the size of the placement cavity generated between the partitions 1 and 2.

[0011] Option 4 is the preferred option of Option 3. A placement box is provided on the top of the base. The placement box is provided with partitions 1 and 2 in the same manner as those in the box body. The placement box is convenient for storing cleaned generator parts or generator parts that do not need to be cleaned, which can effectively avoid the trouble caused by the loss of parts and facilitate the later assembly of the generator. By setting a number of evenly distributed and criss-crossed partitions in the placement box, it is convenient to classify and place the cleaned parts. At the same time, by setting the slide grooves and limit grooves, the size of the placement cavity generated between the partitions can be adjusted according to the size of the parts.
