The radial wind wheel locating device is characterized in that the circumstantial edge of the locating disk is provided with an open slot; the lock pin is arranged on the radial position of the disk; the axis of the lock pin and the radial line of the locating disk are positioned on the same straight line; the axial and circumstantial manufacture errors of a taper slot on the locating disk do not affect the locking effect on the lock pin; the processing cost is lowered, and the wind wheel is more reliable to lock; and lock pin can move along the axial direction and can be manually spirally transmitted or hydraulic pushed.
Description
Technical field
The present invention relates to technical field of wind power generation, particularly the radial wind wheel locking device of one.
Background technique
In wind power generating set, wind wheel lock is generally arranged on the front end of lower velocity shaft, for unit lengthy shut down or unit maintenance state.Fig. 1,2 is the typical structure schematic diagram of wind wheel lock in prior art.As shown in Figure 1, 2, when locking, lock pin 13 is inserted in the positioning hole 12 of positioning disk 11, reaches the machine security lock function to wind wheel.By code requirement, for high-power blower, when locking, can not have gap between lock pin 13 and positioning hole 12, therefore, current structure generally does tapering form lock pin with coordinating of positioning hole.
But the cooperation of tapering is very high to the requirement of precision, lock pin is fixed on support, and positioning hole is on positioning disk, has 6-12, and become circle distribution, positioning disk is arranged on lower velocity shaft, rotates with the axis.Above-mentioned each component all can have certain error to exist in the process manufactured and assemble, and this just can not ensure that lock pin accurately, is reliably inserted in the positioning hole of positioning disk, namely can not accomplish complete taper fit.Once coordinate bad, following consequence can be caused: 1. lock pin can not contact completely with positioning hole, cause localized contact stress excessive; 2. there is gap between lock pin and positioning hole, wind wheel is not locked completely, under wind action, wind wheel can swing back and forth, and produces and impacts, finally cause the damage of wind wheel lock to lock pin.
Summary of the invention
The object of this invention is to provide a kind of wind wheel lock mode, lock pin accurately and reliably can be contacted with positioning disk and location, can ensure that wind wheel can be effectively locked, the working life of wind wheel lock can be extended again.Technological scheme of the present invention is to provide a kind of radial wind wheel locking device, it comprises main shaft, positioning disk, lock pin, lock, lock pin is arranged in lock, wherein, fluting is provided with at the circumferential edges of described positioning disk, described lock pin is arranged on the radial position of disk, and the axis of described lock pin and the radius of positioning disk are positioned on straight line.
Preferably, the axis of described lock pin and the axes normal of main shaft.
Preferably, positioning disk is arranged on main shaft, and the axes normal of main shaft is in positioning disk.
Preferably, described fluting is taper groove, and the front end of described lock pin is taper, and described taper groove is identical with the tapering of taper.
Preferably, described tapering is not more than 60 degree.
Preferably, described positioning disk is evenly distributed with 6,9 or 12 taper groove.
Preferably, described taper groove is straight trough, and its each end face inner is plane.
Preferably, be provided with limit stoper in described lock, described lock pin can be able to have a small amount of circumference to rotate in lock.
The invention has the beneficial effects as follows: on positioning disk of the present invention, the foozle of the axial and circumferential of taper groove all can not have an impact to the locking of lock pin, not only reduces processing cost, also make the locking of wind wheel more reliable.Lock pin movement vertically in lock can be realized by hand power screw transmission or hydraulic drive.

Fig. 3,4 illustrates wind wheel locking device structural representation of the present invention;
Fig. 5 illustrates the graphics of wind wheel locking device of the present invention.
Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing, make above-mentioned and other object of the present invention, Characteristics and advantages will be more clear.Reference character identical in whole accompanying drawing indicates identical part.Deliberately do not draw accompanying drawing in proportion, focus on purport of the present invention is shown.
Below, the present invention is described in detail for composition graphs 3-4.
A kind of radial wind wheel locking device, it comprises main shaft 2, positioning disk 1, lock pin 4, lock 5, lock pin is arranged in lock, it is characterized in that, fluting 3 is provided with at the circumferential edges of described positioning disk, described lock pin is arranged on the radial position of disk, and the axis of described lock pin and the radius of positioning disk are positioned on straight line.In the present invention, the positioning hole of positioning disk is not taper hole, but with the straight trough of tapering, during work, go near lock pin by the taper groove of positioning disk, mobile lock pin inserts the locked position in the taper groove of positioning disk, lock pin is inserted in the taper groove of positioning disk along radial direction, and coordinates with it; Adopt this wind wheel lock mode, on positioning disk, the foozle of the axial and circumferential of taper groove all can not have an impact to the locking of lock pin, not only reduces processing cost, also makes the locking of wind wheel more reliable.Lock pin movement vertically in lock can be realized by hand power screw transmission or hydraulic drive.
In the present invention, fluting is taper groove, and the front end of lock pin is taper simultaneously, and taper groove is identical with the tapering of taper.Can ensure that fluting and lock pin can fit tightly like this.Preferably, tapering is not more than 60 degree.And taper groove is straight trough, its each end face inner is plane.Plane laminating can be more tight.
Limit stoper is provided with in described lock, described lock pin can be able to have a small amount of circumference to rotate in lock, as the rotation of less than 10 degree can be had, positioning disk is at circumference some gap value rotated total, when locking after positioning, if there is point tolerance, adjustment automatically can be carried out according to the position of lock pin in place, the conical surface is fitted completely.
Lock is fixed on support, lock pin can move vertically in lock, the tapering identical with taper groove is processed in the front end of lock pin, available operated by handwheel screw mandrel makes lock pin move axially, or hydraulically promotion lock pin moves axially, lock pin can have a certain amount of circumferencial direction to rotate in lock, is used for compensating the processing between lock pin tapering and positioning disk taper groove or assembly error.
