Description
Technical field
The present invention relates to wind-driven generator technical group field, particularly relate to a kind of novel wind generator group hydraulic pin centralising device and centering method.
Background technique
Hydraulic pin is an important safety mechanism in wind power generating set, when attendant need enter wheel hub inside safeguard time, it first must pin wind wheel lock, lock wind wheel lock step is: a people manually carries out jiggering by high speed shaft brake disc at high speed axle head, what another one people observed lock pin and pin-and-hole at wind wheel lock end aligns situation, 3rd people's compounding practice lock pin, when lock pin and pin-and-hole are to timing, is pinned.The defect of this structure and operation is, because blower fan attendant establishment is at ordinary times mostly two people, needs extra increase by artificial, add cost of labor, when many people operate, coordinate poor accuracy, inefficiency simultaneously so complete above-mentioned work.
Summary of the invention
Object of the present invention be exactly the blower fan that exists to solve prior art when safeguarding cost of labor high, many people cooperation poor accuracy, reduces the problem of working efficiency; A kind of wind power generating set hydraulic pin centralising device is provided; Drive wind wheel to rotate by blade, do not need manpower jiggering, observe pin, hole aligns situation by pointer, align the locking of rear primer fluid pressing system button, structure is simple, operating efficiency and degree of accuracy high, decrease cost of labor.
The present invention also provides a kind of novel wind generator group hydraulic pin centering method.
To achieve these goals, the present invention adopts following technological scheme:
A kind of novel wind power generating set hydraulic pin centralising device, comprise Three-blade wind wheel, main shaft, speedup box, high speed shaft brake disc, lock pin, lock collar, pointer, cabin, cabin is provided with engine room cover, lock collar is fixed on main shaft, main shaft is connected with cabin, and Three-blade wind wheel, main shaft, speedup box, high speed shaft brake disc connect successively, and the side of front portion, cabin is located at by pointer, lock collar is provided with positioning hole, and positioning hole coordinates with lock pin.
Described positioning hole is provided with multiple, and positioning hole is uniform in lock collar.
Described positioning hole is cone shape hole, is arranged with and starts mark line and alignment marker line outside the limit, hole of described cone shape hole.
Described pointer is bonded together by binder and engine room cover front portion.
A kind of novel wind generator group hydraulic pin centering method, comprises the following steps:
1) handheld box is connected in variable blade control system, controls one of them blade and drive oar, drive wind wheel to rotate, open propeller angle by adjustment blade and control wind wheel rotational speed, make rotor position meet the demand of aligning;
2) observe pointer and lock collar index line and align situation, after pointer and the startup mark line at the positioning hole place of lock collar are about to align, made out by handheld box that paddle sheet is suitable to be starched;
3) when three blades are in feather position entirely, wind wheel continues to rotate under effect of inertia, and when pointer is in the middle of startup mark line and alignment marker line, starts hydraulic pin and advance button, lock pin starts to advance, and enters lock collar positioning hole;
4) lock pin and positioning hole are locked put in place, then enter wheel hub and safeguard.
Working principle of the present invention: first lock pin and positioning hole are aligned during use, wind wheel is pinned, then in engine room cover side, one pointer is installed, make directly over pointer tip and hole it, simultaneously carry out mark at each positioning hole place, comprise and start mark line and alignment marker line because lock pin be taper hole, startup time do not need to align especially, because wind wheel lock collar pin-and-hole adopts uniform design, so when pointer and arbitrary pin-and-hole mark at that time, all represent that wind wheel lock pin and pin-and-hole align.When operating lock pin centering in attendant's maintenance process, first will drive oar among the individual blade be in feather position by handheld box, drive wind wheel to rotate by blade, make the rotating speed of wind wheel meet centering demand by the angle controlling to open oar.Wind wheel transmission main shaft drives inner wind wheel lock collar to rotate, and after the start line in wind wheel lock collar and pointer are about to align, again operate handheld box, makes out paddle blade feathering.After Three-blade is all-cis oar, wind wheel relies on inertia to continue to rotate, and when pointer is in start line and opens hydraulic pin during match line centre and advance button, namely starts the locking work of wind wheel lock pin.After locking, attendant just can enter wheel hub and safeguard.Whole process does not need artificial jiggering, and only need 1 ~ 2 people to complete, people from province is laborsaving.
Beneficial effect of the present invention: drive wind wheel to rotate by blade, do not need manpower jiggering, aligns situation by pointer observation pin, hole, align the locking of rear primer fluid pressing system button, structure is simple, operating efficiency and degree of accuracy high, decrease operator's quantity, reduce cost of labor.
