Description
Technical field
The present invention relates to aerogenerator unit safe protect field, more particularly to a kind of Wind turbines hanging object hole safeguard structure with
And the Wind turbines of the safeguard structure are installed.
Background technology
With the attention that Environmental is protected, clean energy resource is quickly grown in recent years, especially wind-power electricity generation, nearly 4 years
Carry out annual increment of installing and be above 100%, Chinese wind turbine total installed capacity amount in 2011 has had reached the whole world first.Wind turbine is general
Projected life be 20 years, in the entire life process of wind turbine, the Maintenance and Repair of wind turbine are to ensure that wind turbine normal table is run
Key means.Wind turbines can be divided into four part such as wind wheel, cabin, pylon and basis.Wind wheel is to catch wind mechanism；Have in cabin
Main shaft, drive gear box, generator etc., predominantly energy conversion elements；Pylon and the structure that basis is support wind wheel and cabin.Mesh
Preceding mainstream wind turbine is mostly hundreds of kilowatts or MW class, generally about tens tons of wind wheel and cabin gross weight.In order to rationally capture wind
Can, cabin is supported on that height is aerial for 60-100 meters, and main running of wind generating set parts are all disposed within cabin by pylon
In, widget is replaced and the transport of service kit is required for the hanging object hole by cabin tail portion.
Fan engine room crane is normally at cabin tail portion, this position is generally disposed with generator, cabin cabinet etc., hanging object space

At the rising of wind turbine cost.
In the wind turbine of operation, there are various structures and measure in fan design producer to solve the problems, such as this.A kind of mode be by
Hanging object structure is transferred in tower, can thus be effectively protected safety when hanging object operation, but there is also from tower
It is interior to need hand haulage to work to cabin, it has not been convenient to the problems such as wind turbine is safeguarded.Another way is the crane cancelled in cabin, is adopted
It is hung in above engine room cover with external crane, such mode needs the trepanning in engine room cover, needs to use external crane, existing
Main problem is that cost is too high, safeguards and once just needs to enter maintenance tool lifting in cabin using primary large-scale crane.
It can be seen that the solution of above-mentioned wind turbine handling still has problem, and cabin handling is the pass that wind turbine is safeguarded
Key channel, it is directly related to the daily maintenance of wind turbine, and in order to preferably serve the maintenance of wind turbine, cabin handling just needs
Fully play effect.It, can design cost be low on hanging object hole, is not take up space and can for the maintenance needs for meeting daily
The safeguard structure leaned on.
