Abstract
A mechanical locking for directly driven wind-powered unit, the locking device during for a kind of wind power generating set maintenance, comprises locking plate, stop pin, guide sleeve, guiding groove, guide finger, handwheel, flat key and nut.Rotation hand wheel, by the connection drive nut of flat key, nut is by screw drive stop pin, and guide finger and guiding groove are converted into straight line motion the rotation of stop pin, and stop pin is moved ahead, until insert locking plate.After locking puts in place, arming pin is reinserted.The utility model mechanical locking is simple to operate, does not need to control the locked lengths of stop pin, and cost is low, and safe and reliable.
Description
Technical field
The utility model relates to wind power generating set, the locking device while being specifically related to a kind of wind power generating set maintenance,
Background technique
Wind power generating set must lock wind wheel when maintenance wind wheel, mostly adopts at present hydraulic lock assembly.Hydraulic lock assembly comprises locking plate, stop pin, hydraulic station, piston, approach switch, guide way.This hydraulic lock assembly is high, the operating difficulties of price not only, and hydraulic oil can leak, and build-up of pressure is not enough, thereby causes locking device poor stability.
Model utility content
In order to overcome existing hydraulic lock assembly, there is the deficiency of operating difficulties, poor stability, the purpose of this utility model is: the mechanical locking that a kind of directly driven wind-powered unit is provided, this mechanical locking is simple to operate, do not need to control the locked lengths of stop pin, cost is low, and safe and reliable.
It is as follows that the utility model solves the technological scheme that its technical problem adopts:
A kind of mechanical locking of directly driven wind-powered unit, described mechanical locking comprises locking plate, stop pin, guide sleeve, guiding groove, guide finger, handwheel, flat key and nut, described locking plate is relative with stop pin and put, in the middle of locking plate, have locking aperture, this locking aperture is a through hole, and the size of locking aperture, shape and position are all suitable with the fore-end of stop pin; The rear end part of stop pin is equipped with a handwheel, and flat key is housed on handwheel, and this flat key is connected with nut, and this nut is threaded with stop pin, at stop pin, guide sleeve is housed outward, has guiding groove in guide sleeve, and the guide finger being located on stop pin is inserted in this guiding groove.
On described guide sleeve, be provided with an arming pin, this arming pin inserts guide sleeve, and passes guide sleeve until stop pin.
The mechanical locking of the directly driven wind-powered unit of the utility model rotates by rotation hand wheel drive nut, thereby drive the stop pin being spirally connected with nut, because the guide finger being connected with stop pin is plugged in guiding groove, thereby the rotation of stop pin is converted into the straight line motion of advancing forward along guiding groove, until stop pin is inserted in locking plate, realize locking.
Compare with existing hydraulic lock assembly, the utility model mechanical locking has following beneficial effect:
1, simple to operate
Rotation hand wheel during the utility model operation, is converted into straight line motion by mechanical connection mechanism rotatablely moving, and stop pin is inserted in locking plate, realize locking, simple to operate, do not need to control the locked lengths of stop pin, also make the cost of whole locking device.
2, locking device is safe and reliable
Structure of the present utility model is component of machine connection set, and the Security that can produce hydraulic fluid leak from existing hydraulic lock assembly, affects locking device is different, and the utility model reliable in structure is used safety.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the mechanical locking of a kind of directly driven wind-powered unit of the utility model.
In figure, 1. locking plate, 2. stop pin, 3. guide sleeve, 4. handwheel, 5. nut, 6. flange, 7. little pressing plate, 8. guide finger, 9. arming pin, 10. flat key, 11. guiding grooves, 12. oil holes.
Embodiment
Figure 1 shows that an embodiment of the mechanical locking of a kind of directly driven wind-powered unit of the utility model.This mechanical locking comprises locking plate 1, stop pin 2, guide sleeve 3, guiding groove 11, guide finger 8, handwheel 4, flat key 10 and nut 5.Locking plate 1 is relative with stop pin 2 and put, and in the middle of locking plate 1, has locking aperture, and this locking aperture is a through hole, and the size of locking aperture, shape and position are all suitable with the fore-end of stop pin 2.The rear end part of stop pin 2 is equipped with a handwheel 4, and flat key 10 is housed on handwheel 4, and flat key 10 is connected with nut 5, and nut 5 is threaded with stop pin 2.Guide sleeve 3 is housed outside stop pin 2, has guiding groove 11 in guide sleeve 3, the guide finger 8 being located on stop pin 2 is inserted in guiding groove 11, and passes outside guide sleeve 3, also has oil hole 12 in guide sleeve 3.On guide sleeve 3, be provided with an arming pin 9, this arming pin 9 inserts guide sleeve 3, and passes guide sleeve 3 until stop pin 2.The effect of arming pin 9 is to prevent stop pin 2 misoperations.
In the rear end of nut 5, flange platen 6 is housed, nut 5 is pushed down and supported to this flange platen 6, thereby play the effect of support lock rationed marketing 2.End face at handwheel 4 is equipped with little pressing plate 7, pushes down handwheel 4, makes handwheel 4 spacing.
Operating process of the present utility model is as follows:
First extract arming pin 9, rotation hand wheel 4, by the connection drive nut 5 of flat key 10, nut 5 is by screw drive stop pin 2, and guide finger 8 and guiding groove 11 are converted into straight line motion the rotation of stop pin 2, and stop pin 2 is moved ahead, until insert locking plate 1.After locking puts in place, arming pin 9 is reinserted.Otherwise unlock and carry out operation.
