Embodiment
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.Can't carry out the impeller of wind power generating set in view of prior art accurately, simply and lock centering, the utility model provides a kind of impeller rational in infrastructure, that reliability is high, time saving and energy saving to lock centralising device.
Be the structural representation that the impeller lock centralising device of the wind power generating set of present embodiment is connected with the brake disc of wind-driven generator referring to Fig. 1, the impeller of present embodiment is locked centralising device and is comprised: drive unit 2 and actuation gear 1.
In Fig. 1, actuation gear 1 meshes with the brake disc 3 of wind-driven generator; Drive unit 2 links to each other with actuation gear 1, drives actuation gear 1 and rotates.
The method that drive unit 2 drives actuation gear 1 rotation can have multiple, a kind of method can drive the motor (not shown) that actuation gear rotates for being provided with in drive unit 2, rotate by switch control motor, when the staff opened switch, motor rotated and drives the actuation gear rotation; During off switch, motor stops operating.Also have a kind of mode as shown in Figure 1, on drive unit 2, be provided with and drive the handwheel 4 that actuation gear rotates.
The mode that drive unit 2 drives actuation gear 1 rotation comprises above-mentioned several method, but is not limited to this.
Referring to the partial enlarged drawing 3a among Fig. 2 and Fig. 2 and Fig. 3 b, Fig. 2 carries out the scene graph that centering is operated for the impeller lock centralising device of wind power generating set; Fig. 3 a is depicted as the connection diagram of actuation gear and brake disc engagement; The position of locking plate and spring bolt concerns schematic representation shown in Fig. 3 b, and Fig. 3 a and the magnification ratio of Fig. 3 b in Fig. 2 are about 1: 25.
Describe below in conjunction with Fig. 2, Fig. 3 a and Fig. 3 b.When using this device to carry out the centering operation of impeller lock, can earlier this device be placed in brake disc near, the external tooth of actuation gear 1 with the brake disc 3 of wind-force electrical machinery is meshed.The staff operates drive unit 2 and drives actuation gear 1 rotation, because actuation gear 1 is meshed with the external tooth of brake disc 3, therefore can drive brake disc 3, locks by the rotating drive impeller of brake disc 3 and carries out centering.
Shown in Fig. 2, Fig. 3 a and Fig. 3 b, in wind-force electrical machinery, but 5 motions of brake disc 3 driven gear casees by the transmission of movement of gear-box 5, just can realize the rotation of the wheel hub of impeller 1, and the spring bolt 10 of impeller lock and the locking hole on the locking plate 7 are carried out centering.
For improving the validity of impeller lock centering, the radius of actuation gear 1 should be less than the radius of brake disc 3, the staff is when carrying out manual adjustment thus, actuation gear 1 rotates a week, brake disc 3 only rotates a very little angle, therefore can play the effect that brake disc 3 is finely tuned, thereby improve the validity of impeller lock centering.
Shown in Fig. 3 b, have only when wheel hub rotates to the accurate centering of the locking hole that makes on the locking plate 7 and spring bolt 10, spring bolt 10 just can enter locking hole on the locking plate 7 to realize the locking of impeller lock.
It is as follows to utilize this device to carry out the step of impeller lock centering: at first this device is installed near the positions brake disc 3, and actuation gear 1 is meshed with the brake disc 3 of wind-driven generator.After wind-driven generator was shut down smoothly, whether the locking hole on the spring bolt 10 that the staff estimates the impeller lock and the locking plate 7 centering.As centering not, can operate drive unit 2 to drive brake disc 3 rotations, finally the transmission of gear-box 5 motions by wind-driven generator realizes the rotation of impeller 8 and the accurate centering of impeller lock.
The impeller lock centralising device that present embodiment provides, simple and reasonable, safe and reliable, low cost of manufacture.By using speed reducer and actuation gear to carry out the centering of impeller lock, can save blower fan attendant's muscle power and time, alleviate attendant's labor intensity, improve work of maintenance personnel efficient.
It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment's technological scheme of the utility model.
