The big maintenance cost for reducing wind power generating set, mitigate the workload repaired during collector ring of generator abrasion and shorten failure
Time.
To achieve the above object, technical scheme provided by the utility model is：A kind of wind power generating set is double-fed asynchronous
Prosthetic device on collector ring of generator tower, including the support of cutter, knife rest, knife rest, radial guidance, axial guidance, axial feed spiral shell
Bar and its axial feed adjusting handle, radial feed screw rod and its radial feed adjusting handle；The knife rest support is removably
At the support installation position of wind power generating set；Axial guidance and the axial feed screw rod is arranged on knife in parallel with each other
In frame support；The radial guidance is arranged on axial guidance and axial feed screw rod, can be by axial feed screw drive
Slided on axial guidance；The knife rest is slidably mounted on radial guidance, positioned at the collector ring side of double-fed asynchronous generator, and
Radial feed screw rod is connected with, can be slided by radial feed screw drive on radial guidance；The cutter is removably pacified
On knife rest, inputted using the power of wind power generating set, double-fed asynchronous generator is kept rotation, realize to double-fed asynchronous
The current collection ring surface of generator carries out machining, to complete to repair on the tower of double-fed asynchronous generator collector ring, wherein passing through
Axle, radial feed screw rod can realize that the axial direction of cutter and radial feed are adjusted.
The knife rest support uses the form of cage cantilever beam, and is designed as split-type detachable structure.
The split-type detachable structure of the knife rest support uses symmetric design.
The knife rest support is bolted on double-fed asynchronous generator rear end cap.
The knife rest support uses semi arch supporting construction.
The knife rest support does the strong point using the cabin or double-fed asynchronous generator footing of wind power generating set, supports knife
Frame is processed operation.
The utility model compared with prior art, has the following advantages that and beneficial effect：
1st, analyzed in terms of financial cost, need lower tower reparation after collector ring abrasion or directly scrap, cost is higher, uses
It can directly repair, can be processed using the power of unit, very succinctly, greatly on tower after prosthetic device of the present utility model
The big utilization rate for reducing rehabilitation cost, improving product, conveniently used in narrow space at the scene.
2nd, analyze, repaired with prosthetic device of the present utility model, it is only necessary to pull down current collection ring casing in terms of workload
, it is not necessary to collector ring is dismantled, reduces the workload of Field Force.
3rd, analyze from time cost, repaired with prosthetic device of the present utility model, it is only necessary to 4 hours or so
Recover the normal power generation of owner, it is more than working day at least to want 3 for following tower reparation, greatly reduces the generated energy damage of owner
Lose.
4th, knife rest supporting construction is relatively simple, using site-assembled mode, can be met by simple Automatic manual transmission
Requirement, reduce the skill set requirements to Field Force.
