Abstract
The utility model relates to a wind generating set blade locking device is applied to wind generating set's hoist and mount in -process. This wind generating set blade locking device, characterized by: including be used for with the hub above the alveolar surface of the ring gear meshing of blade on becoming the oar flange, the one end of alveolar surface is equipped with and is used for the boss be connected with the support of hub the inside pre -installation. The beneficial effects of the utility model are that, part that this locking device has a tooth's socket just in time with the ring gear meshing of blade bearing, pass through the bolt fastening with tooth's socket part adjacent plane and on the hub, through this blade locking device, can realize the reliable fixed of blade, avoid the rotation of blade.
Description
Technical field
The utility model relates to a kind of wind generator set blade locking device, is applied in the hoisting process of wind power generating set.
Background technique
The wind energy industry of current China is in the fast-developing stage, and along with the continuous increase of unit capacity, the weight of each parts of blower fan is more and more heavier, and setting height(from bottom) is more and more higher, installs difficulty and constantly increases.
The impeller of 5MW blower fan is combined by wheel hub and three blades, and after combination, the gross weight of impeller is about 127.4t, and diameter is 128m.First a hoisting aids machinery is used to coordinate main Hoisting Machinery to be erected by the impeller combined during impeller lifting, then by main hoisting machinery separately by its hoisted in position.Wherein the hoisting point position of main hoisting machinery is the root of two blades, and Aided Machine hoisting point position is the root of residue another one blade.
If therefore blade rotates in impeller combination and hoisting process, the stability of Lift-on/Lift-off System will be destroyed, very easily cause the serious accident that Hoisting Machinery topples because of unstability, so firmly need lock three blades with true safety in impeller combination and hoisting process.In addition the later stage blade maintenance or operation maintenance personnel when entering operation in wheel hub, also need by impeller and blade locking, to ensure equipment and personal security.
Summary of the invention
In order to make up the deficiencies in the prior art, the utility model provides one, prevents the wind generator set blade locking device that it rotates in impeller combination and hoisting process.
The utility model is achieved by the following technical solution:
A kind of wind generator set blade locking device, it is characterized in that: comprise the alveolar surface for engaging with the ring gear on the vane propeller-changing flange above wheel hub, one end of alveolar surface is provided with the boss II for being connected with the bearing pre-installed inside wheel hub, and the side of described boss II is provided with positioning hole.
For ease of with less material, the support effect played, another section of described alveolar surface is provided with and is also provided with boss I, is provided with floor between two boss I and boss II; The height of described boss I is less than the height of boss II, and the floor near boss I is ramp structure.
The beneficial effects of the utility model are, this locking device has the part of teeth groove just in time to engage with the ring gear of blade bearing, and the plane adjacent with teeth groove part is bolted on wheel hub, by this blade locking device, the reliable fixing of blade can be realized, avoid the rotation of blade.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
In figure, 1, alveolar surface 2, boss I3, boss II, 4, positioning hole, 5, floor.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises the alveolar surface 1 for engaging with the ring gear on the vane propeller-changing flange above wheel hub, one end of alveolar surface 1 is provided with the boss II3 for being connected with the bearing pre-installed inside wheel hub, the side of described boss II3 is provided with positioning hole 4, another section of described alveolar surface is provided with and is also provided with boss I2, floor is provided with between boss I2 and boss II3, the height of described boss I2 is less than the height of boss II3, and the floor 5 near boss I2 is ramp structure.
Use this to fix this device to be engaged with vane propeller-changing bearing ring gear by alveolar surface.After blade assembling, blade is by being embedded in the stud bolt of root of blade together with pitch variable bearings flange tight joint; The boss II that alveolar surface is adjacent is provided with five bolts hole, the bearing pre-set can be fixed together by Bolt Connection in this locking device and wheel hub; By the mechanical coupling at above two places, blade links together with the fixed bearing in wheel hub, and blade is locked, and can not rotate, and after impeller installation, three blades all become oar to feather position, removes blade locking device.
Impeller has been assembled on ground, the stud bolt connected with bearing flange until blade is fastening complete after, utilize this blade locking device to be locked by blade, prevent blade from rotating.
