Description
Technical field
The present invention relates to wind power plant brakes field, more particularly to wind turbines rotor locking mechanism.
Background technology
The main function of wind wheel lock collar is brake disc when being shut down as Wind turbines, only in wind-driven generator group maintenance
Use, when wind power generating set is overhauled, typically first passing through brakes stalls wind wheel and main shaft, then wind wheel locking machine
The locking pin of structure puts in the shutdown hole of wind wheel lock collar, and wind wheel is locked, it is ensured that the safety of personnel and equipment.Existing wind wheel lock collar
The generally disc structure of integral type, material are generally the low-alloy high-tensile structural steel forged, are disposed with circumferentially on disk
The conical wind wheel lock of distribution shuts down hole.Due to just locking stopping function using wind wheel only in maintenance shut-downs, therefore shut down
Internal surface of hole can produce corrosion because long-time is idle, cause frictional force to increase, and need to implement wind when Wind turbines will be safeguarded
Wheel lock timing, locking pin, which can not normally enter, shuts down hole；Need to release wind wheel lock timing after the completion of maintenance, easily cause locking pin
It is stuck, can not normally exit, influence wind power generating set normal work.
Existing megawatt-level wind unit wind wheel locking mechanism is generally hydraulic-driven pattern, conventional for the above situation
Way be to operate hydraulic system determine the higher hydraulic pressure of organization cylinder offer to wind wheel lock, locking pin is overcome due to corrosion
Caused frictional force, realize that wind wheel locking and unblock, the rated operating pressure of hydraulic system are generally 16MPa, and according to theory
Calculate and practical experience is learnt, for corrosion serious situation, hydraulic system pressure reaches 35MPa even more during practical operation
Height, too high hydraulic pressure can have undesirable effect to hydraulic system element and cylinder seal, potential safety hazard be present, and cause
The waste of the energy；If higher hydraulic system pressure does not reach requirement still, could also be completed by means of jack, it is time-consuming to take
Power, very big difficulty is brought to execute-in-place, or even wind wheel locking mechanism and wind wheel lock collar can be damaged, add maintenance cost.

Wheel lock pin enters lock or moves back the hole clipping slid in or out during lock.But the program does not provide the specific pattern of hole clipping in wind wheel lock collar.
Chinese patent 201320068832.8 discloses a kind of wind-driven generator group wind-wheel lock collar, and the lock collar provides one kind
Wind-driven generator group wind-wheel lock collar, casting is taken, cost is cheap and can meet density of load requirement.But in the lock collar
Wind wheel lock shut down hole still for directly process, once shutdown hole inwall corrosion, the locking pin of caused wind wheel locking mechanism is entered
Go out difficult or even stuck problem.
Chinese patent 201320485069.9 discloses a kind of wind wheel locking device of wind-driven generator, the device provides
A kind of wind wheel locking device of wind-driven generator, including stop pin, locking disk and cabin chassis, are wherein provided with locking disk and are used for
The pin-and-hole of stop pin is inserted, the pin-and-hole is directly processed on locking disk, once shutting down hole inwall corrosion, caused wind wheel is locked
The locking pin of mechanism passes in and out difficult or even stuck problem.
Found by retrieving, above-mentioned patent is still not able to be effectively prevented from wind wheel locking mechanism in terms of structure and principle
Stuck phenomenon.
The content of the invention
To solve above mentioned problem existing for prior art, the present invention will design a kind of combined wind-power wind wheel lock collar, with solution
The locking pin of certainly existing wind wheel lock collar wind wheel locking mechanism caused by lock hole corrosion passes in and out difficult or even stuck problem, makes
Wind wheel locking mechanism neatly can be locked and unlocked to wind wheel, ensure the safe operation of wind power generating set.
