2; 2) wind wheel upwind carrys out flow disturbance greatly, and direction is random; 3) this device long service life, is greater than 20 years.Now many use Split type hydraulic locking devices, its drawback is as follows: 1) due to the stochastic uncertainty of wind speed and direction, causes spring bolt accurately cannot aim at locking hole; 2) detachable locking device, requires that machining accuracy is high and installation requirement is high; 3) as locking hole conquassation was lost efficacy, need be fallen by wind wheel integral demounting with kiloton pedrail crane, expense more than 100,000, and will change extremely inconvenience, and even Xu Fan factory just can implement.4) under huge inertia effect, hydraulic rod seal ring unbalance stress, easily produces leakage of oil, causes locking device fault.
Model utility content
Technical problem to be solved in the utility model is, overcomes the defect of prior art, provides a kind of spring bolt easily to aim at locking hole, and self precision easy to process is high, and installation requirement is low, and it is convenient to change, without the wind wheel locking device of leakage of oil risk.
For solving the problems of the technologies described above, the utility model proposes a kind of wind wheel locking device, it comprises spring bolt, it also comprises screw rod and the shaping locking support of integrally casting, locking support is provided with the U-groove bevel of both ends open, locking support is provided with lockhole perpendicular to U-groove bevel side, this lockhole is divided into two by U-groove bevel, spring bolt and lockhole are slidably matched to make the front end of spring bolt also finally can enter another part of lockhole through U-groove bevel, screw rod is arranged on locking support, screw flight section promotes spring bolt when being threaded to make bolt rotary with the axial screw of spring bolt and moves axially along lockhole.
After adopting said structure, compared with prior art, the utility model has the following advantages: because integrally casting is shaping, locking support intensity is high, milling lockhole just can complete through clamped one time, not only processing is simple, and precision is high, during use, locking support is arranged on main bearing platen, easy to assembly, less demanding to assembly precision, screw rod mechanism formula screw drive spring bolt, precision is high, easy to operate, during inefficacy, only locking support need be pulled down and namely complete locking device integral demounting, blower fan just can complete, dismounting, easy for installation, expense is low, simultaneously easy to maintenance, good reliability, owing to passing through bolt rod driving, so there is no leakage of oil risk.
As improvement, locking support is provided with the end cap for installing screw rod, and like this, screw rod mounting structure is simple, simultaneously screw rod and spring bolt easy accessibility.
As improvement, spring bolt sidewall is provided with restraining groove, and what match with restraining groove is be installed on locking support and the locating stud of lockhole is stretched in local, like this, can prevent spring bolt from exceeding upper and lower, and simple and reliable for structure.
As improvement, the shape of spring bolt end is guiding frustoconic shape, and like this, spring bolt easily inserts locking hole.

Embodiment
Below the utility model is described in further detail:
The utility model wind wheel locking device, it comprises spring bolt 1, it also comprises screw rod 2 and the shaping locking support 3 of integrally casting, locking support 3 is provided with the U-groove bevel of both ends open, locking support 3 is provided with lockhole 6 perpendicular to U-groove bevel side, this lockhole 6 is divided into two by U-groove bevel, spring bolt 1 and lockhole 6 are slidably matched to make the front end of spring bolt 1 also finally can enter another part 7 of lockhole 6 through U-groove bevel, screw rod 2 is arranged on locking support 3, the thread section of screw rod 2 is threaded to promote spring bolt 1 when screw rod 2 is rotated with the axial screw of spring bolt 1 and moves axially along lockhole 6.
The utility model wind wheel locking device is installed on wind-driven generator, namely locking support 3 is arranged on main bearing platen 12, be bolted, the U-groove bevel of both ends open coordinates with annular locking plate 4 activity of wind wheel, in double team state, but do not clamp, along with the rotation of annular locking plate 4, on annular locking plate 4, the uniform locking hole 5 of circumference can free in and out U-groove bevel, annular locking plate 4 will be fixed by locking exactly, and namely spring bolt 1 and lockhole 6 are slidably matched to make the front end of spring bolt 1 also finally enter another part 7 of lockhole 6 through the locking hole 5 entering U-groove bevel.
For adapting to the arc of annular locking plate 4 bottom U-groove bevel.
Locking support 3 is provided with the end cap 8 for installing screw rod 2.
Spring bolt 1 sidewall is provided with restraining groove 9, and what match with restraining groove 9 is be installed on locking support 3 and the locating stud 10 of lockhole 6 is stretched in local, and it is spacing that this locating stud 10 carries out circumference to spring bolt 1 simultaneously.
The shape of spring bolt 1 end is guiding frustoconic shape.
Screw rod 2 is arranged on and locking support 3 refers to the head axial limiting of screw rod 2 is arranged on end cap 8, and screw rod 2 can be rotated, and screw rod 2 rotates and drives spring bolt 1 to move.
In this example, annular locking plate 4 is the annular inner portion of wind energy facility main shaft 11, when using the utility model, by locking support 3 integral installation on main bearing platen 12, be bolted, and main shaft 11 is arranged on main bearing platen 12 and can mutually rotate, the another part 7 also finally entering lockhole 6 through the locking hole 5 entering U-groove bevel by the front end of spring bolt 1 locks main shaft 11, main shaft 11 locks, namely wind wheel locks, owing to having the advantages that lockhole 6 is divided into two by U-groove bevel, another part 7 also finally entering lockhole 6 locally through the locking hole 5 entering U-groove bevel of spring bolt 1 simultaneously, so the supporting structure form of spring bolt 1 to annular locking plate 4 is the supporting structure of simply supported beam, substantially improve the stressed of spring bolt 1.
Comparatively before hydraulic separate body formula locking device, two locking holes 5 on the utility model locking support 3 be clamped one time milling out, the coaxality in hole is high, and registration is insensitive to assembly error.Can be easy to wind wheel locking under the wind speed that disturbance is random, adopt mechanical type screw drive in addition, reliability is high, safeguards, assembling, dismounting be all very convenient.
The utility model locking process, uses spanner rotating screw bolt 2, thus spring bolt 1 is moved forward, spring bolt 1 front end is passed locking hole 5 and is entered another part 7 of lockhole 6, until restraining groove 9 end encountered by locating stud 10, spring bolt 1 can be avoided to cross stroke, thus complete the locking of wind wheel; The utility model releasing process, reverse mobile spring bolt 1.
