Description
Technical field
The utility model belongs to wind power generating set, relates in particular to a kind of blade locking device that is applied on the unit.
Background technique
At present, large-scale wind power generator incorporated in power network group all is to become oar type wind-powered electricity generation unit, pitch-controlled system is the vitals of unit, generally include and become oar driving and pitch variable bearings, become the oar driving and can drive the pitch variable bearings rotation, thereby drive blade rotates to change blade along the axis of blade propeller pitch angle, namely become oar, then reach the purpose that changes generating unit speed and power.Break down when needing repairing at regular maintenance and pitch-controlled system, when pinning wind wheel, also need pin blade and occur to become oar to prevent it, to avoid bringing hidden danger to unit and maintenance man's safety.The effect of blade locking device is exactly to pin blade, guarantees unit and personal security.
With reference to Fig. 1, Fig. 2 and Fig. 3, the outer ring 2 of pitch variable bearings is fixedly connected on the wheel hub, and ring gear 1 and the blade of pitch variable bearings are bolted to connection together, becomes oar and drives when driving the rotation of pitch variable bearings ring gear, will drive blade and rotate.Existing blade lock 3 comprises a base 31 and an engaging tooth 32 that is fixed together with base 31, and base 31 is installed on the web 4 of wheel hub by attachment bolt 33.When the wind-powered electricity generation unit in when operation, blade must be in rotary state, at this moment, engaging tooth 32 is in position shown in Figure 3, namely engaging tooth 32 is that direction deviates from the tooth of pitch variable bearings ring gear 1.When needs locking blade, by changing the direction of the engaging tooth 32 on the blade lock 3, insert it in the teeth groove of ring gear 1 of pitch variable bearings, to reach the purpose of pinning blade.The weight of this blade lock is heavier, and needs assembling-disassembling bolt, therefore needs a plurality of people to cooperate locking or the relieving that just can finish the blade lock, and efficient is lower, and Safety performance is not high.
Summary of the invention
For the volume that overcomes existing wind-powered electricity generation unit blade locking device is large, Heavy Weight, complicated operation, need that the simultaneously deficiency of compounding practices of a plurality of people, the utility model provide that a kind of volume is little, lightweight, simple to operate, the blade locking device of wind-powered electricity generation unit that people can independent operation.
The utility model is that the technological scheme that its technical problem of solution adopts is:
A kind of blade locking device of wind-powered electricity generation unit, this locking device is installed on the web of wind-powered machine unit hub, described locking device comprises base, handle, connecting lever, lock pin, lock pin track and fixed plate, described base is fixedly mounted on the web of wheel hub, described lock pin track is fixedly connected with fixed plate, the axis of described lock pin track is positioned on the diameter of pitch variable bearings ring gear, described lock pin is positioned at the lock pin track, the engaging tooth of described lock pin one end for matching with the tooth of pitch variable bearings ring gear, one end of the described lock pin the other end and connecting lever is hinged, the other end of described connecting lever and handle the first articulating point are hinged, and the second articulating point and the fixed plate of handle are hinged.
Further, described blade locking device also comprises safety pin, and described fixed plate and handle are provided with corresponding to locking station and the safe pin-and-hole that unclamps station.Certainly, also can adopt other orientation types.
The beneficial effects of the utility model are mainly manifested in: this locking device volume is little, lightweight, and does not need assembling-disassembling bolt, and a people just can operate, and has effectively simplified maintenance operation, has reduced the maintenance cost of wind-powered electricity generation unit, has shortened maintenance time.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 4～Fig. 6, a kind of blade locking device of wind-powered electricity generation unit, this locking device comprises lock pin 5, connecting lever 6, handle 7, base 8, lock pin track 9 and fixed plate 10, described base 8 is fixedly mounted on the wheel hub web 4 by bolt 12, described lock pin track 9 and fixed plate 10 and 8 fixing companies of base, the axis of described lock pin track 9 is positioned on the diameter of pitch variable bearings ring gear 1, described lock pin 5 is positioned at lock pin track 9 and can moves reciprocatingly, one end of lock pin 5 is engaging tooth, this engaging tooth can insert in the teeth groove of pitch variable bearings ring gear 1, one end of pivot pin 5 the other ends and connecting lever 6 is hinged, the first articulating point of the other end of connecting lever 6 and handle 7 is hinged, and the second articulating point and the fixed plate 10 of handle 7 are hinged.
This locking device also comprises safety pin 11, and fixed plate 10 is provided with corresponding to locking station and two safe pin-and-holes that unclamp station, and handle 7 is provided with a safe pin-and-hole.Certainly, also can adopt other orientation types.
Be illustrated in figure 4 as the state when decontroling blade, at this moment, engaging tooth on the lock pin 5 is not inserted in the teeth groove of pitch variable bearings ring gear 1, blade can rotate, hinder the rotation of blade in order to prevent handle 7 automatic rotatings, safety pin 11 can be inserted in the safe pin-and-hole corresponding on fixed plate 10 and the handle 7.When needs locking blade, only need to unclamp safety pin 11, handle with sleeve 7, can in the lock pin track, 9 do straight reciprocating motion by connecting lever 6 band pendulum lock pin 5, the engaging tooth of lock pin 5 one ends is inserted in the teeth groove of pitch variable bearings ring gear 1, stop the rotation of blade, then safety pin 11 is inserted in the corresponding safe pin-and-hole of fixed plate 10 and handle 7 and gets final product.
This scheme is different from existing technological scheme, decontroling or locking in the operating process of blade, need not remove bolt, rotates whole blade locking device, but only needs handle with sleeve, just can achieve the goal.Therefore, a people just can operate, and has improved Safety performance, and has shortened the time of safeguarding, has reduced maintenance cost.
