Description
Technical field
The utility model relates to wind generating unit technical field, is specifically a kind of wind wheel locking device.
Background technique
Wind turbines rotor feature: 1) wind wheel inertia is huge, up to 10
6kgm
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, the wind wheel locking device of not easy oil leakage.
For solving the problems of the technologies described above, the utility model proposes a kind of wind wheel locking device, it comprises the oil cylinder of piston rod as spring bolt, it also comprises the shaping locking support of integrally casting, oil cylinder is connected with locking support, locking support is provided with for locking with the annular of wind wheel the U-groove bevel that disk activity coordinates, this U-groove bevel frees in and out for the uniform locking hole of circumference on annular locking plate, locking support is provided with the lockhole axially arranged along locking hole, this lockhole is divided into two by U-groove bevel, piston rod and lockhole are slidably matched to make the front end of piston rod also finally enter another part of lockhole through the locking hole entering U-groove bevel.
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, but locking 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 having the advantages that lockhole is divided into two by U-groove bevel, the front end of piston rod also finally enters another part of lockhole through the locking hole entering U-groove bevel simultaneously, so the supporting structure form of piston rod to annular locking plate is the supporting structure of simply supported beam, this supporting structure makes black box radial force reduce, piston rod can not produce destruction to black box at the annular locking plate of support, so not easy oil leakage.
As improvement, oil cylinder is provided with run-length encoding device, like this, can the comparatively accurate control piston throw of lever, by the Stroke Control of piston rod within the specific limits, improve locking and unlock efficiency.
As improvement, the shape of piston rod end is guiding frustoconic shape, and like this, piston rod easily inserts locking hole.

As shown in the figure: 1, locking support, 2, oil cylinder, 3, piston rod, 4, annular locking plate, 5, locking hole, 6, lockhole, 7, another part, 8, run-length encoding device, 9, main shaft, 10, main bearing platen.
Embodiment
Below the utility model is described in further detail:
The utility model wind wheel locking device, it comprises the oil cylinder 2 of piston rod 3 as spring bolt, it also comprises the shaping locking support of integrally casting 1, oil cylinder 2 is connected with locking support 1, locking support 1 is provided with the U-groove bevel for coordinating with annular locking plate 4 activity of wind wheel, this U-groove bevel frees in and out for the uniform locking hole 5 of circumference on annular locking plate 4, locking support 1 is provided with the lockhole 6 axially arranged along locking hole 5, this lockhole 6 is divided into two by U-groove bevel, piston rod 3 and lockhole 6 are slidably matched to make the front end of piston rod 3 also finally enter another part 7 of lockhole 6 through the locking hole 5 entering U-groove bevel.
A kind of wind wheel locking device of the utility model is installed on wind-driven generator, namely locking support 1 is arranged on main bearing platen 10, 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 and lockhole 6 are slidably matched to make the front end of spring bolt 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.
Oil cylinder 2 is provided with run-length encoding device 8, and run-length encoding device 8 is commercially available, and the control of the hydraulic system of oil cylinder 3 adopts prior art.
The shape of piston rod 3 end is guiding frustoconic shape.
In this example, annular locking plate 4 is the annular inner portion of wind energy facility main shaft 9, when using the utility model, by locking support 1 integral installation on main bearing platen 10, be bolted, and main shaft 9 is arranged on main bearing platen 10 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 locks main shaft 9, main shaft 9 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 simultaneously, so the supporting structure form of spring bolt to annular locking plate 4 is the supporting structure of simply supported beam, substantially improve the stressed of spring bolt.
Comparatively before hydraulic separate body formula locking device, two locking holes 5 on the utility model locking support 1 be clamped one time milling out, the coaxality in hole is high, and registration is insensitive to assembly error.Can be easy under the wind speed that disturbance is random wind wheel locking, reliability is high, safeguard, assembling, dismounting all very convenient.
The utility model locking process, the piston rod of oil cylinder moves forward, and the front end of piston rod is passed locking hole 5 and entered another part 7 of lockhole 6, by run-length encoding device 8 feedback position signal to the hydraulic system control piston throw of lever, thus completes the locking of wind wheel; The utility model releasing process, retraction piston rod.
