Description
Technical field
The present invention relates to technical field of wind power generation, particularly a kind of radially wind wheel locking device.
Background technique
In the wind power generating set, the wind wheel lock generally is installed in the front end of lower velocity shaft, is used for long-term shutdown of unit or unit maintenance state.Fig. 1,2 is the typical structure schematic representation of wind wheel lock in the existing technology.Like Fig. 1, shown in 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.Press code requirement, for high-power blower, when locking, can not be gapped between lock pin 13 and the positioning hole 12, therefore, present structure is generally done the tapering form to lock pin and cooperating of positioning hole.
But the cooperation of tapering is very high to the requirement of precision, and lock pin is to be fixed on the support, and positioning hole is on positioning disk, has 6-12, becomes circle distribution, and positioning disk is installed on the lower velocity shaft, rotates with the axis.Above-mentioned each component all can have certain error to exist in the process of making and assembling, and this just can not guarantee that lock pin is inserted in the positioning hole of positioning disk accurately, reliably, promptly can not accomplish complete taper fit.In case cooperate badly, can cause following consequence: 1. lock pin can not contact with positioning hole fully, causes local contact stress excessive; 2. have the gap between lock pin and the positioning hole, make not locking fully of wind wheel, under wind action, wind wheel can swing back and forth, and lock pin is produced impact, and causes the damage of wind wheel lock at last.
Summary of the invention
The purpose of this invention is to provide a kind of wind wheel lock mode, make lock pin can contact with positioning disk accurately and reliably and the location, can guarantee that wind wheel can be prolonged the working life of wind wheel lock again by effective locking.Technological scheme of the present invention provides a kind of radially wind wheel locking device; It comprises main shaft, positioning disk, lock pin, lock; Lock pin is arranged in the lock, wherein, is provided with fluting at the circumferential edges of said positioning disk; Said lock pin is arranged on the radial position of disk, and the axis of said lock pin and the radius of positioning disk are positioned on the straight line.
Preferably, the axis normal of the axis of said lock pin and main shaft.
Preferably, positioning disk is arranged on the main shaft, and the axis normal of main shaft is in positioning disk.
Preferably, said fluting is the tapering groove, and the front end of said lock pin is taper, and the tapering of said tapering groove and taper is identical.
Preferably, said tapering is not more than 60 degree.
Preferably, be evenly distributed with 6,9 or 12 tapering grooves on the said positioning disk.
Preferably, said tapering groove is a straight trough, and its inner each end face is the plane.
Preferably, be provided with limit stoper in the said lock, said lock pin can have a spot of circumferential rotation in lock.
The invention has the beneficial effects as follows: the foozle of the axial and circumferential of tapering groove all can not exert an influence to the locking of lock pin on the positioning disk of the present invention, has not only reduced processing cost, also makes the locking of wind wheel more reliable.Lock pin moves vertically in lock and can be realized by manual power screw or hydraulic drive.
Description of drawings
Fig. 1,2 has illustrated the typical structure schematic representation of wind wheel lock in the existing technology;
Fig. 3,4 has illustrated wind wheel locking device structural representation of the present invention;
Fig. 5 has illustrated the graphics of wind wheel locking device of the present invention.
Embodiment
For make above-mentioned purpose of the present invention, feature and advantage can be more obviously understandable, does detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention, it will be more clear making above-mentioned and other purpose, characteristic and advantage of the present invention.Reference character identical in whole accompanying drawings is indicated identical part.Painstakingly do not draw accompanying drawing in proportion, focus on illustrating purport of the present invention.
Below, be elaborated in conjunction with Fig. 3-4 couple the present invention.
A kind of radially wind wheel locking device; It comprises main shaft 2, positioning disk 1, lock pin 4, lock 5; Lock pin is arranged in the lock, it is characterized in that, is provided with fluting 3 at the circumferential edges of said positioning disk; Said lock pin is arranged on the radial position of disk, and the axis of said lock pin and the radius of positioning disk are positioned on the straight line.Among the present invention, the positioning hole of positioning disk is not a taper hole, but has the straight trough of tapering; During work, the tapering groove of positioning disk is gone near the lock pin, move the locked position in the tapering groove that lock pin inserts positioning disk; Lock pin is inserted in the tapering groove of positioning disk along radial direction, and cooperates with it; Adopt this wind wheel lock mode, the foozle of the axial and circumferential of tapering groove all can not exert an influence to the locking of lock pin on the positioning disk, has not only reduced processing cost, also makes the locking of wind wheel more reliable.Lock pin moves vertically in lock and can be realized by manual power screw or hydraulic drive.
Fluting is the tapering groove among the present invention, and the front end of lock pin is taper simultaneously, and the tapering of tapering groove and taper is identical.Can guarantee that like this fluting and lock pin can fit tightly.Preferably, tapering is not more than 60 degree.And the tapering groove is a straight trough, and its inner each end face is the plane.Fitting in the plane can be more tight.
Be provided with limit stoper in the said lock; Said lock pin can have a spot of circumferential rotation in lock, as the rotation below 10 degree can be arranged, positioning disk is at the gap value of circumferentially total some rotation; When behind the location, locking; If point tolerance is arranged, can adjust in placely according to the position of lock pin automatically, the conical surface is fitted fully.
Lock is fixed on the support; Lock pin can move in lock vertically; The front end of lock pin is processed into the tapering identical with the tapering groove, and available operated by handwheel screw mandrel moves axially lock pin, or moves axially with hydraulic way promotion lock pin; Lock pin can have a certain amount of circumferencial direction to rotate in lock, is used for compensating processing or the assembly error between lock pin tapering and the positioning disk tapering groove.
