Description
Technical field
The utility model belongs to technical field of wind power generation, relates to a kind of wind wheel lock.
Background technique
The wind wheel of wind power generating set is solid of rotation, and attendant enters wind wheel or works in cabin, must lock wind wheel, otherwise the rotation of wind wheel and the high speed shaft fast turn-around that causes, great harm can be brought to attendant.Therefore wind power generating set is equipped with wind wheel lock.
The wind wheel lock of current wind power generating set have a manual direct-insert with hydraulic drive type: manual direct-insert wind wheel lock, centering requires higher, and lock pin inserts lockhole and compares effort, and efficiency is low; Hydraulic drive type wind wheel lock complex structure (must configure oil hydraulic pump), accuracy of manufacturing is high, and cost is also high, and there is seepage, and poor in self has potential safety hazard.
Summary of the invention
In order to overcome the wind wheel lock of existing wind-driven generator centering require high, troublesome poeration, efficiency are lower, cost is high, there is the deficiency of potential safety hazard, the utility model provide a kind of reduce centering require, operate mechanical type wind wheel lock that is light, that reduce costs, eliminate safe hidden trouble.
The utility model solves the technological scheme that its technical problem adopts:
A kind of mechanical type wind wheel lock, comprise wind wheel locking plate, described wind wheel locking plate has the lockhole that the front end for lock pin is inserted, described wind wheel lock also comprises guide sleeve, fixed plate and Worm gear feed screw propulsion device, described guide sleeve and fixed plate are fixed in cabin seat, described lock pin is sleeved in described guide sleeve slidably, the center line of described guide sleeve, the center line of lock pin and the center line of described lockhole are located along the same line, the afterbody of described lock pin is fixedly connected with the angle of rake screw mandrel of Worm gear feed screw, described Worm gear feed screw propulsion device is arranged on described fixed plate, described Worm gear feed screw propulsion device comprises screw mandrel, worm-and-wheel gear and power intake, described power intake is coaxial with the worm screw of described worm-and-wheel gear, the worm gear of described worm-and-wheel gear engages with described screw mandrel.
Further, described power intake is electric wrench joint or manual wrench joint.Power input can be carried out by electronic or manual.
Further, described lock pin inside is provided with oil leab, and filler opening is located at the conical section of lock pin front end, respectively has an oil outlet, at described filler opening, lubricating cup is housed on conical section surface and cylindrical section surface.
The afterbody of described lock pin is connected with the angle of rake wire rod thread of Worm gear feed screw.This is preferred a kind of Placement, certainly, also can be other means of fixation.
When selecting thread connecting mode, described lock pin radial direction has locking hole, and Cock screw withstands screw mandrel through described locking hole.Usual needs two Cock screws are located and are prevented screw mandrel from loosening.
The beneficial effects of the utility model are mainly manifested in: 1, equipment volume is little, lightweight, simple and compact for structure, low cost of manufacture; 2, lock pin and wind wheel locking plate lockhole surface of contact can be lubricated by grease up, and surface of contact between lock pin and guide sleeve, the insertion making lock pin and the surface friction drag exited reduce greatly; 3, Worm gear feed screw propulsion device is owing to comprising worm drive, inputs a very little moment of torsion and just can produce larger thrust or pulling force, make wind wheel lock operation more laborsaving.4, because worm drive has self-locking property, because the wind effect of carrying makes lock pin rollback after wind wheel locking can be prevented, avoid producing serious accident.5, Worm gear feed screw propulsion device input shaft is equipped with manual/electric wrench adapter, connects ratchet wrench during power-off, during energising, connect electric wrench, flexible and convenient operation.
