Description
Technical field
The present invention relates to fan repair technical fields, and in particular to a kind of blade repair platform and installation method.
Background technique
Currently, with the rapid development of national economy, a kind of renewable energy of the wind energy as great competitiveness, process is several
Research and development in 10 years has been completed from Applied D emonstration to practical transformation, the increasingly attention by countries in the world, wind
The annual maintenance cost of pylon factory critical component blade is at high cost, and domestic wind tower factory maintenance special equipment technology content is not high, high
The product of science and technology is less.To have reached technical requirement on design: perfect performance, manufacturing cost is low, and flexible operation is reliable, installation maintenance
It is convenient, high safety and reliability.User is allowed to feel well-content product.Good social benefit is brought to society.
Blade is easy to be corroded by destructions such as sand and dust, salt fogs blower in operation, increases blade drag, and revolving speed reduces,
Fan efficiency reduces；It is serious to be also possible to make the breakage of blade large area, cracking, or even fracture, so the maintenance of blade is wind field
A very important job.
Blower fan tower barrel can also encounter the problem to be treated such as corrosion, grease stain after running for a period of time, but close to leaf
Piece, position to be processed are the problems that wind field faces, traditional solution, are that rope is hung down from cabin by maintenance personal
Play the position operation for being sent to and needing repairing；Or rent crane and play small cage operation, both methods are all than relatively hazardous, safety
It is unable to get guarantee, and time-consuming, expense, heavy workload.
Summary of the invention
The characteristics of for the prior art, the present invention provide a kind of blade repair platform, and the stage+module is on fan engine room top
Portion, and have the function of back-and-forth motion and oscilaltion, it may be implemented to operate blade root entire area, and once mounting is overhauled
Three blades of whole Fans, install convenient are easy to use.
The present invention provides a kind of blade repair platforms, including the first support platform, the second support platform and operating platform；

Right end be fixedly connected by right connection board 117.
Left support bar 111, right support bar 112 are fixed with the left side of nacelle top and the right guardrail by U bolt respectively
Connection, it is ensured that the first support platform 1 does not shake, here left support bar 111, right support bar 112 and middle support rod 113
It is all channel steel, channel steel length with U bolt is fixed to fence 31 after being finely adjusted according to two fences, 31 actual range
On, the left mounting plate 114 and right mounting plate 115 being arranged here are welded onto respectively on left support bar 111 and right support bar 112,
T-type junction is formed, T-type junction position is separately fixed at T-type junction two sides using two U-bolts, to guarantee first
Support platform 1 does not shake.
Further, the single upper support frame 12 includes upper support bar 121, and the upper support bar 121 is vertically laid on
On two middle support rods 113, wherein the lower part of upper support bar 121 is fixed with lower front mounting plate 122 and lower rear mounting plate respectively
123, the top of the single middle support rod 113 is fixed with and 123 phase of the lower front mounting plate 122 and lower rear mounting plate respectively
Corresponding upper front mounting plate 118 and upper rear mounting plate 119, the lower front mounting plate 122 and upper front mounting plate 118 and upper rear installation
It is fixedly connected by bolt and nut between plate 119 and lower rear mounting plate 123.
By the way that upper support bar 121 is arranged, upper support bar 121 is channel steel, passes through lower front mounting plate 122 and lower rear mounting plate
123 with upper front mounting plate 118 and it is upper after mounting plate 119 be correspondingly connected with, upper support bar 121 is stably mounted at down
On support frame, it is then used further to the second support platform 2 of support.
Further, it is in reversed F-typed mounting rack 21 that second support platform 2, which includes two, and two mounting racks 21 are distinguished
Correspondence is fixedly mounted on two upper support bars 121 vertically, and the lower end of the single mounting rack 21 is fixed with lower installation

Connecting rod connection, and it is enclosed cuboid between two the second reinforcing rods 26 and two mounting racks 21 being arranged, it can make
What operating platform 3 can consolidate is placed on mounting rack 21 and will not drop out from mounting rack 21 in sliding process, here
The first reinforcing rod 23, the second reinforcing rod 26 and bolt taut band binding bar 24 be channel steel.
Further, the operating platform 3 is fork hydraulic lifting platform, the lower part left and right ends pair of operating platform 3
It should be slidably mounted in the notch of two mounting racks 21, the top of operating platform 3 is fixedly installed with fence 31.
Here operating platform 3 is gone up and down by hydraulic control, and fork hydraulic lifting platform is that lifting common in life is flat
Platform, structure do not repeat them here, and maintenance personal can be such that operating platform 3 moves forward or backward by push-and-pull operating platform 3,
And fence 31 can prevent maintenance personal from dropping out from operating platform 3.
Further, the top of two mounting racks 21 is equidistantly equipped with several along long the first spiral shell to direction of mounting rack 21
Hole, the lower part left and right ends of the operating platform 3 are equipped with the second screw hole corresponding with the screw hole, and the operating platform 3 is logical
Bolt and nut is crossed to be fixedly connected with two mounting racks 21.
When operating platform 3 is moved to suitable position by service personnel, operating platform 3 and mounting rack 21 can be passed through into spiral shell
Bolt nut is fixedly connected, and realizes being locked to operating platform 3, this is fixed as discontinuity and fixes, and specific length is according to the
The spacing of one screw hole and the second screw hole measures.
Further, 31 rear end of fence is equipped with shutter door 32.
The shutter door 32 of setting facilitates maintenance personal to be entered on operating platform 3 from shutter door 32.
