Description
Technical field
The present invention relates to wind-power electricity generation area of maintenance, specifically a kind of pitch-controlled system part replacement attending device.
Background technology
Pitch-controlled system is the critical component of large-scale wind driven generator, and current large-scale wind driven generator major part uses feather
System speed-variable is controlled, and the revolving support gear for driving reductor drive blade by pitch motor rotates blade, pitch-controlled system
Design service life be 20 years, in this section of use time, the parts in pitch-controlled system may be safeguarded with
And change.
Pitch-controlled system is that will become oar cabinet to be sling using row in wheel hub cavity, during installation, and is installed in wheel hub cavity, wheel hub
Entirety is sent to wind field, and impeller is combined into blade, and impeller is lifted into cabin using crane.If pitch-controlled system needs to change body
The smaller parts of product, workmen can be passed in and out by the manhole between cabin and wheel hub, and carrying parts carries out installation dimension
Shield.But if pitch-controlled system needs to change the larger change oar parts of volume ratio, manhole is not enough to pass through, then before needing to repeat
Step, is hung down impeller from cabin with crane, removes blade, changes pitch-controlled system parts, then impeller is installed hangs on, and to be disappeared
The very big production and transport of consumption and lifting cost are used.
The content of the invention
In view of the above-mentioned problems existing in the prior art, the application provides a kind of pitch-controlled system part replacement attending device,
Purpose is to solve the problems, such as that pitch-controlled system large volume part replacement is safeguarded to be difficult.
To achieve the above object, the technical scheme of the application use is：Pitch-controlled system part replacement attending device, specifically
Including：The elevator and assembly pulley of interconnection；The elevator, including：Elevator body and steel wire rope, the steel wire rope one
Terminate on elevator body, direction is changed by assembly pulley, the other end is provided with suspension hook, and pitch-controlled system parts hang over suspension hook
On；The assembly pulley includes：Pulley and pulley bracket, pulley are fixed on pulley bracket, and pulley bracket is fixed on wheel hub entrance
Place.
Further, the elevator body is fixed on the optional position that can coordinate with assembly pulley.
Further, the elevator body is safeguarded for pitch-controlled system part replacement by steel wire rope and provides pulling force.
Further, guide rail is installed above pulley, guide rail is fixed on pulley bracket, part to be replaced hangs over pulley
On, specified location in wheel hub is directly slided into along guide rail.
The present invention can obtain following technique effect due to using above technical scheme：The application is drawn by elevator
Dynamic steel wire rope is hung at wheel hub and water conservancy diversion cover opening pitch-controlled system parts by assembly pulley, and workmen scoops out and sets afterwards
Complete to safeguard replacing for wheel hub is entered.So that the maintenance of the larger pitch-controlled system parts of Electricity Generation unit wheel hub inner volume and
Replacing becomes feasible, it is not necessary to pull down impeller, saves a large amount of production and transports and hoisting cost.
