So that the diameter that the spot size that laser pick-off module is received is popped one's head in laser pick-off module is consistent substantially, at this point, logical
Crossing manipulation adjustment device can be realized the Dock With Precision Position of fan blade and axial fan hub.
It should be noted that hot spot cross-sectional strength is in Gauss point since laser beam has certain angle divergence characterization
Cloth, therefore the center of laser beam is commonly referred to be light intensity most strength, further, since laser beam is sent out closer to laser
It penetrates at the position of module, the dissipating effect of laser beam is smaller, therefore control device is by constantly enclosing fan blade
It is adjusted around the center line of laser beam and constantly that laser emitting module and laser pick-off module is close to each other next real
Now to the adjustment of fan blade.
The embodiment of fan blade installation method of the invention:
As shown in Figures 2 and 3, the installation method of fan blade includes the following steps:
S1: one of them of laser pick-off module 6 and laser emitting module 5 are mounted on fan blade 1, another peace
Mounted in the corresponding position of axial fan hub 2, mobile monitoring device is mounted on fan blade 1.
Specifically, laser pick-off module 6 and laser emitting module 5 have multipair, each laser pick-off mould in the present embodiment
Block 6 is installed on axial fan hub 2, and each laser emitting module 5 is installed on fan blade 1.As shown in figure 3, the present embodiment
Middle axial fan hub 2 and fan blade 1 are connected through a screw thread structure installation and fix, and screw connection structure includes threaded post 3 and screw thread
Hole 4, setting is correspondingly arranged that there are six spiral shells there are six threaded hole 4 on axial fan hub 2 on fan blade 1 in specific the present embodiment
Line column 3.Six threaded holes 4 are arranged at equal intervals along the circumferential direction of axial fan hub 2, similar, and six threaded posts 3 are also along week
Being correspondingly connected on end face for fan blade 1 is set at equal intervals to direction.Three pairs of laser pick-off moulds are provided in the present embodiment altogether
Block 6 and laser emitting module 5, three laser pick-off modules 6 are separately positioned in three threaded holes 4 of distribution triangular in shape, phase
Corresponding, three laser emitting modules 5 are separately positioned on 3 end of corresponding three threaded posts.It should be noted that attached drawing 3
Three stains on middle fan blade represent a laser emitting module 5, and three stains on axial fan hub 2 represent one
Laser pick-off module 6.Threaded hole 4 can be set there are three more than in other embodiments, such as the number of threaded hole 4 is three
A, four, five, six etc..Three pairs or more, for example, five have also can be set in laser emitting module 5 and laser pick-off module 6
To, six pairs, seven equities, it should be noted that when for five clock synchronizations, the arrangement of each laser emitting module 5 and each laser receiving module
Mode is pentagon；When for six clock synchronizations, the arrangement mode of each laser emitting module 5 and each laser receiving module is six sides
Shape.
S2: fan blade 1 is lifted at height and position corresponding with axial fan hub 2 using adjustment device；
Specifically, the present embodiment middle regulator is large-scale crane, before installation, axial fan hub 2 is by way of lifting
It is lifted on blower support tower and is installed fixation, is then lifted by crane fan blade 1 by loop wheel machine opposite as axial fan hub 2
At height and position.It should be noted that during lifting by crane fan blade 1, being filled by height monitoring in the present embodiment
It sets and the sling height of fan blade 1 is monitored, height monitoring device is laser ranging system, laser ranging in the present embodiment
Device can measure the distance between fan blade 1 and blower support tower bottom end, when the distance of measurement and the height of axial fan hub 2
After substantially uniform, that is, it can determine whether fan blade to be lifted to corresponding height and position.
S3: it is by adjusting device that fan blade 1 is mobile to the stronger direction of laser intensity, work as laser light in moving process
When strong information dies down or cuts off, school is carried out to 1 position of fan blade by way of reversely adjusting 1 moving direction of fan blade
Just；
Specifically, starting each Laser emission after fan blade 1 is lifted at corresponding height and position in the present embodiment
Module 5 and each laser pick-off module 6, due to laser beam have diversity, when fan blade 1 apart from axial fan hub 2 farther out when,
The spot diameter that laser beam is radiated on axial fan hub 2 is larger, mobile by corresponding laser pick-off by manipulation adjustment device
Module 6 covers in corresponding hot spot, since the light intensity of laser beam centerline is stronger, and closer to laser emitting module 5
Position laser beam diverging it is smaller, light intensity is also stronger, so during the installation process on the one hand control device can pass through manipulation
Adjustment device by fan blade 1 to drawing close at beam center line position, on the other hand can also be by fan blade 1 to axial fan hub 2
Direction promotes.During the installation process, due to high wind or regulation it is excessive and when fan blade 1 being caused larger displacement deviation occur,
Laser receiver can receive the laser intensity signal that light intensity becomes smaller at this time, when control device receives the laser intensity to become smaller
After signal, control device can manipulate adjustment device and move in the opposite direction, rectify to realize to 1 offset deviation of fan blade
Just.It should be noted that accelerometer can monitor the direction of displacement of fan blade 1 in real time, when larger position occurs in fan blade 1
When moving deviation, control device can manipulate adjustment device and be acted along the opposite direction with accelerometer monitoring direction of displacement,
To be corrected to the position of fan blade.
S4: repeating step S3, until received laser facula size is consistent with the diameter that laser pick-off module 6 is popped one's head in,
Then fan blade 1 is docked on axial fan hub 2 by adjusting device.
Specifically, continuous close with laser emitting module 5 and laser pick-off module 6, laser pick-off module 6 is connect
The laser beam spot sizes of receipts can gradually become smaller, when the diameter phase one that the spot size of laser beam is popped one's head in laser pick-off module 6
(it should be noted that the spot size of laser beam is consistent with the diameter that laser pick-off module 6 is popped one's head in the present embodiment when cause
Refer to substantially uniform, spot diameter can be considered consistent with the difference of probe diameter in certain threshold value), it at this time can be true
Determine fan blade 1 and axial fan hub 2 realizes docking substantially, then adjusts device for each screw thread of fan blade 1 by manipulation
Column 3 is inserted at corresponding threaded hole 4, that is, completes the installation of fan blade.It should be noted that in the present embodiment
Above embodiments essentially describe the basic principles, principal features and advantages of the present invention.The technical staff of the industry
It should be appreciated that the present invention is not limited to the above embodiments, the above embodiments and description only describe the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these variation and
Improvement all fall within the protetion scope of the claimed invention.
