Embodiment
With reference to embodiment, the present invention is described in detail.
Total is by telescopic arm, ball-screw, angle pulley, haulage cable, tensioning apparatus, adaptive tune
Save the composition such as connecting rod, ac three-phase asynchronous motor, turbine worm reducer, tooth sector and electric-control system.When inspection platform exists
Do not go up to the air work when, total is all fixedly attached on platform, and is contracted in most short status.When inspection platform lift-off is arrived
After specified location, start motor via reducer and tooth sector drives turn-screw, with the rotation of leading screw, be fixed on second
Nut on level telescopic arm sleeve is displaced outwardly, at the same time, and the steel wire rope that is tensioned pulls third level slip expansion arm and the
Two-level sleeve synchronously stretches out.When inspection platform be pulled to specified location and blade is encircled reach working condition after, telescopic arm
It is in the lock state, withstands on blower fan tower barrel outer wall that there is provided horizontal supporting force and the power that swings of resistance.
The end of ball-screw 1 is arranged in supporting bearing base 2 by bearing 3, and supporting bearing base is bolted to shrouding 4
On connection frame 5, connection frame 5 is welded on the end of first order telescopic arm 6；Ball-screw nut 7 is bolted to shrouding 8 and
In two grades of connection frameworks 9；Second level connection framework 9 is welded on the end of second level telescopic arm 10；Guide pad 11 and walking guide pad
12 are assemblied in the installation groove of second level telescopic arm 10；Third level connection framework 13 is welded on the end of third level telescopic arm 16；
Elongation steel wire rope mobile terminal 14 is welded in third level connection framework 13；Leading block 15 is bolted to third level telescopic arm
On 16；Third level telescopic arm 16 is assemblied in second level telescopic arm 10 by guide pad 11 and walking guide pad 12；Elongation traction steel
Cord fixing end 17 is welded on the front end of first order telescopic arm 6；Hauling block 18 is welded on before second level telescopic arm 10 by support
End；Support connecting plate 19 is bolted in the front end of third level telescopic arm 16；Shrink steel wire rope leading block 20 and pass through branch
Frame is welded on below the front end of first order telescopic arm；Shrink rope traction pulley 21 and second level telescopic arm is welded on by support
10 rear end.
（Telescopic arm）Agent structure is as shown in figure 3 above, and overall assembling is as shown in figure 1, installation such as Fig. 2 in detection platform
It is shown.Start motor after telescopic arm elongation order is connected to, by power-conversion be ball-screw 1 by reductor and gear mechanism
Rotary motion；Because leading screw is fixed on first order telescopic arm by spring bearing, its nut is moved in the horizontal direction, and then band
Employ the second level telescopic arm that bolt is fastened on nut；The hauling block for being fixed on second level telescopic arm afterbody drives traction steel
Cord is moved, and one section of steel wire rope is fixed on first segment telescopic arm, and the other end is fixed on third level telescopic arm close to motor
One end；By above step, after electric motor starting, first order telescopic arm is fixed on motionless in detection platform, and second and third level is stretched
Contracting arm is moved to away from motor drive direction simultaneously, i.e. the overall elongation action of telescopic arm；Electricity is started when being connected to after telescopic arm shrinks order
Machine is reversely rotated, and is rotated by ball-screw, nut level is close to motor drive direction；Second level telescopic arm is now fixed on close to electricity
The contraction rope traction pulley driving of generator terminal shrinks steel wire rope, make third level telescopic arm follow second level telescopic arm synchronous to by
Nearly motor drive direction, i.e. telescopic arm contractile motion.
Due to using the turbine worm reducer with good self-locking property in transmission mechanism, only motor rotation can guarantee that
Turn that the stretching motion of telescopic arm could be driven, otherwise can not, so accurate positioning, safety.In the telescopic arm sleeve of relative motion
Inwall is provided with the guide runner of self-lubricating property, the also structural stability of enhanced sleeve while reducing friction resistance, and
And reduce the noise that motion is produced.
