Electric barring device for wind turbines

Abstract

The invention discloses an electric barring device used for a wind generating set. The electric barring device used for the wind generating set comprises a fixing support, a movable base board, a plurality of first connection devices, a motor speed reducer, a control box, a displacement adjusting device, a pinion and a big gear, wherein the fixing support is in a groove shape and comprises a second connection device, a plurality of oblong holes and a threaded hole; a plurality of through holes are formed in the position, corresponding to the oblong holes, of the movable base board; the motor speed reducer is fixed to the movable base board through a third connection device; the displacement adjusting device comprises an adjusting screw rod and a locking nut; the pinion is installed on an output shaft of the motor speed reducer through a fourth connection device; and the big gear is installed on the side face of a brake disc of a high-speed shaft of a gear case of the wind generating set through a fifth connection device. By adjusting the adjusting screw rod, the motor speed reducer can drive the pinion to move up and down in the vertical direction to be engaged with or disengaged from the big gear. The electric barring device used for the wind generating set is safe, reliable, convenient to dismount and mount and good in universality, and improves the work efficiency.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an electric barring device for a wind power generating set. Background technique [0002] Wind power technology is an energy conversion technology with relatively mature technology, relatively low cost, little impact on the environment, and the most development scale and commercial development prospects. With the emergence of the energy crisis, wind power has become more and more popular, and the single-unit capacity of wind turbines has also been rising. For large-megawatt doubly-fed wind turbines, during installation and commissioning, the coaxiality between the output shaft of the gearbox and the input shaft of the generator is related to the stability of equipment operation and the life of important components, and the impeller and When the main shaft is docked with the screw hole in the air, it may be necessary to fine-tune the main shaft to rotate a small ang...

AI Technical Summary

Problems solved by technology

Although the above-mentioned wind turbine cranking mechanism can realize the automatic cranking function, the whole device is fixed and cannot be adjusted, and has poor adaptability, so it cannot be applied to other wind power generating sets
