At present, China has become that global wind-powered electricity generation installation scale is maximum, fastest-rising market.By the end of the year 2016, I
State adds up wind-powered electricity generation installation up to 1.69 hundred million kilowatts, increases 23,370,000 kilowatts of installation newly then, installation scale and speedup are sure to occupy the first in the world.
Wind turbines are the complicated towering generating equipments of large size, are typically mounted at the severe remote districts of natural environment,
The test of various extreme climates and wind load complicated and changeable is subjected in During Process of Long-term Operation.
Unavoidably it is present with some exceptions or failure in Wind turbines (abbreviation wind turbine) During Process of Long-term Operation, at this point, wind
The aerodynamic brake of machine implements feathering brake process under control system control, and wind speed round is made to continuously decrease up to substantially static,
Its axis pin insertion wind wheel locking plate lockhole is made wind wheel fully locked by then manual operation wind wheel latch gear.After wind wheel locking,
Maintenance personnel's wheel hub of being allowed for access carries out necessary examination and maintenance work.Wind wheel latch gear is higher to reliability requirement, is
Ensure the important device of boarding personnel safety and unit equipment safety.
Typical wind wheel latch gear is mainly made of the axis pin and propulsive mechanism and its connector that are axially reciprocal movement.
Referring to Fig. 1, wherein axis pin 1 can be moved back and forth along own axes, be inserted into or disengage the lockhole of wind wheel locking plate 4, propulsive mechanism and
Its connector 2 can be automatic device, and such as hydraulic cylinder or hand gear, such as handwheel are connected in rack 3, for pin
The axial reciprocating operation of axis 1；Rack 3 is equipped with the hole that can accommodate 1 axially reciprocating of axis pin；, wind wheel locking plate 4 and wind wheel wheel
Hub, which is connected as one, to be rotated and rotates with wind wheel, which is provided with the lockhole for being inserted into or disengaging for axis pin 1.Wherein rack 3 and wind
Wheel locking plate 4 is not belonging to wind wheel latch gear.
, it is necessary to shut down when fan operation exception or failure, necessary examination and maintenance are carried out by maintenance personnel's boarding, are safeguarded
Personnel are before wheel hub is entered, and wind turbine, which starts aerodynamic brake, makes wind speed round continuously decrease up to substantially static, then manual operation
Axis pin is inserted into the fully locked wind wheel of wind wheel locking plate lockhole by wind wheel latch gear, and maintenance personnel can enter safely wheel hub.
In practical engineering application, propulsive mechanism and its connector possessed by typical wind wheel latch gear is typically more
Complexity, especially self-propelled machine structure have certain demand to hydraulic pressure or power supply, and it also requires mating accurate reliable locking hole hole
Position detecting system, this undoubtedly adds the cost of Wind turbines, and complicated structure also reduces the reliability of system.
Utility model content
The purpose of this utility model is in the case where ensuring the use functional conditions of wind wheel latch gear, by Curve guide impeller, is carried
Its high reliability simultaneously reduces system cost.
The technical solution of the utility model is：A kind of horizontal shaft wind-power unit wind wheel latch gear, including axis pin, active catch
Plate, caging bolt and stop nut, axis pin are axially reciprocal movement, and head carries 20 ° of chamferings, facilitate insertion or disengage wind wheel
Locking plate lockhole, afterbody carry operation handle, and for holding operation, sideboard one end is equipped with circular hole, and the other end is equipped with opening
Card slot, circular hole are set in caging bolt, and for opening card slot cocker in the caging bolt of the other end, sideboard can be around circular hole one side
Caging bolt positive and negative rotation, rotates forward, and opening card slot can reliably be stuck in corresponding caging bolt, after effectively preventing axis pin
It alters, rotates backward, you can opening card slot is made to be disengaged with corresponding caging bolt, two caging bolts are located at axis pin both sides and install
In rack, the circular hole of sideboard and opening card slot are corresponded respectively to, each caging bolt is equipped with two stop nuts, and first
A stop nut is by the appropriate /V of caging bolt and is fixed on rack, and second stop nut makes the appropriate /V of sideboard
Stability of rotation it is flexible.
The advantageous effect of above-mentioned technical proposal is to add sideboard and two groups of caging bolts and /V spiral shell in design
Mother when sideboard opening card slot is stuck in caging bolt, alters after can effectively prevent axis pin, and axis pin tail end adds handle, convenient
Hand-held.The technical program eliminates the more complicated propulsive mechanism of typical wind wheel latch gear and its connection, has evaded certainly
Demand of the propulsive mechanism to hydraulic pressure or power supply and locking hole hole location detecting system is moved, simplied system structure improves wind wheel lock
Pin assembly functional reliability makes its operation reliable quick, while reduces infrastructure cost by a relatively large margin.
