Description
Technical field
The utility model relates to the adjustable test base of a kind of aerogenerator.
Background technology
For the double-fed wind power generator of routine, must test its performance before dispatching from the factory.Before the test, need with its output shaft by shaft coupling with accompany the output shaft of test-run a machine (3400KW frequency changer) to be coupled.
Owing to accompany the center of test-run a machine (3400KW frequency changer) output shaft to fix, the height at the output shaft center of double-fed wind power generator is lower than the height of accompanying test-run a machine (3400KW frequency changer) output shaft center, need install a test base below double-fed wind power generator additional.And in the coupling operation process, also need a crane to carry out mate-assist, just can finish this work.Concrete operations are: double-fed wind power generator is fixed on the test base earlier, by crane double-fed wind power generator is winched on the testing table.On short transverse, for height that guarantees double-fed wind power generator output shaft center and the consistance of accompanying test-run a machine output shaft centre-height, to double-fed wind power generator and test base integral body be sling with crane toward contact, the steel plate of polylith 0.5 millimeters thick that superposes in the bottom of test base then, with crane double-fed wind power generator and test base are put down again, will test base by bolt then and be fastened on the testing table.When the polylith steel plate superposes, owing to certain clearance is arranged between the steel plate, in the time of will testing base and be fastened on the testing table with bolt, the center of double-fed wind power generator will sink, like this, the height at the output shaft center of double-fed wind power generator with accompany the height at test-run a machine output shaft center again with inconsistent.At this moment, need once more double-fed wind power generator and test base integral body to be sling, and then the steel plate that increases by 0.5 millimeters thick in the bottom of test base is adjusted with crane.So, need to adjust repeatedly repeatedly, just can make the height at the output shaft center of double-fed wind power generator reach consistent with the height of accompanying test-run a machine output shaft center.When adjusting on the direction, also need by crane double-fed wind power generator and test base are winched to the appropriate location earlier, and then knock the test base with copper rod and iron hammer and come mobile double-fed wind power generator, carry out and accompany aligning of test-run a machine output shaft all around.Because the very bad control of distance that double-fed wind power generator moves often also needs to adjust repeatedly repeatedly, and two motor output shafts are aligned.
The whole complicated operating process that is of coupled connections, the working time is long, and workload is big, inefficiency, labour intensity is big.
Because accompanying the bearing portions of test-run a machine output shaft is sliding bearing structure, higher to the connection accuracy requirement of double-fed wind power generator output shaft, generally below 0.2 millimeter.If when two output shafts connect by shaft coupling, precision surpasses 0.2 millimeter, then can cause the motor vibrations to strengthen, and bearing temperature exceeds standard, even damages motor bearings.
