Adopt the offshore platform blower fan hanging method of the present invention's offshore platform blower fan described above Lift-on/Lift-off System, first blower foundation 370 is installed, then with a loop wheel machine 310, No. two loop wheel machines 320, the blade 11 of headframe type loop wheel machine 200 difference lifting fan, cabin 12, tower cylinder 13,14,15, the height in installation process is regulated by the suspender 230 of headframe type loop wheel machine.Each parts can be placed on a loop wheel machine respectively, No. two loop wheel machines, headframe type loop wheel machine operating range are rationally local, convenient lifting and installation, loop wheel machine coordinates with each member in tight, improve efficiency of assembling, by the height in the suspender adjustment installation process of headframe type loop wheel machine, adapt to regulate each component height in fitting process, assembling is more efficient, improves operational security.
The operating process of this offshore platform blower fan hanging method has multiple detailed description of the invention.
Please combine in the lump and refer to Figure 12 ~ 21, illustrate that the present invention adopts the specific embodiment of the offshore platform blower fan hanging method of offshore platform blower fan Lift-on/Lift-off System described above below.
Better at operating environment, the lower situation of wind speed, as the hanging method under wind speed about 12m/s (Hoisting Program one) as shown in Figure 12 to Figure 15:
1) basis 370 is first installed.
2) be then cabin 12 and the assembling of blade 11: first by cabin 12 tractor truck be positioned at below blade 11, transversely guide rail 350 and longitudinal rail 360 move to the below of headframe type loop wheel machine 200, being sling in cabin 12 with suspender 230 puts to being positioned at certain altitude place, cabin body 380 is placed on telescoping bracket 221, before this, be lifted in cabin in the process of rising as avoiding telescoping bracket 221 and suspender to interfere, need first telescoping bracket 221 to be bounced back, until bottom cabin body 380 higher than telescoping bracket after again telescoping bracket 221 is stretched out, and whole middle erecting stage 220 is fixed, then cabin 12 is put on telescoping bracket.After on the telescoping bracket 221 that cabin is put in middle erecting stage, rotate the wheel hub 16 of front end, cabin, to adjust attachment face wheel hub filling blade, with loop wheel machine 310, blade 11 is sling simultaneously, complete the assembling of blade 11 and wheel hub 16, a blade is often installed in fitting process, wheel hub is rotated 120 degree to install next blade.
3) assembling of tower cylinder: can utilize the synchronous erection tower cylinder 13,14,15 of No. two loop wheel machines 320 in the process of hoisting blade 11, the segmentation of tower cylinder is transported to blower foundation 370 and installs by No. two loop wheel machines 320.
4) assembling of cabin and tower cylinder: after tower cylinder has lifted, Mobile derrick formula loop wheel machine 200, adjustment height, will complete the assembling of cabin and tower cylinder by suspender.
Operating environment is poor, in the larger situation of wind speed, as the hanging method one of wind speed in 12m/s ~ 20m/s situation, as shown in Figure 16 to Figure 18 (Hoisting Program two):
1) basis 370 is first installed.
2) assembling of tower cylinder: because wind speed is larger, for avoiding rocking of tower cylinder in hoisting process, first with No. two loop wheel machines 320, tower cylinder is moved to below loop wheel machine 200, then by suspender 230, tower cylinder is sling, the tower cylinder holding device 241 utilizing tower wound packages to join auxiliary device 240 before lifting blocks tower cylinder, in lifting process, tower wound packages is joined auxiliary device 240 and tower cylinder and is synchronously risen, and relative tower cylinder is static, is installed on basis 370 after utilizing headframe type loop wheel machine 200 to be sling by tower cylinder.
3) assembling of cabin and blade: identical with Hoisting Program one, it should be noted that after tower cylinder need be waited to have lifted, just can carry out the assembling of blade and cabin wheel hub.
4) assembling of cabin and tower cylinder: identical with Hoisting Program one.
In the larger situation of wind speed, as wind speed 12m/s ~ 20m/s hanging method two, as shown in Figure 16 to Figure 20 to Figure 21 (Hoisting Program three):
1) basis 370 is first installed.
2) assembling of tower cylinder: identical with scheme two.
3) cabin and tower wound packages are joined: after tower cylinder has lifted, and directly utilize headframe type loop wheel machine 200 to lift on 12 to the tower cylinder of cabin, method is identical with scheme one.
4) assembling of blade: after the rigging out of cabin, utilize a loop wheel machine 310 by fixing in blade 11 handling to the blade mounting arrangement 410 of lifting table 400, then operation makes lifting table 400 upwards rise blade 11 along upright guide rail 270, simultaneously near Mobile derrick formula loop wheel machine 200 to cabin, headframe type loop wheel machine 200 is utilized to complete the assembling in blade and cabin.
Hoisting Program one is under nominal situation, wind speed very little or calm time Hoisting Program, under the program, the lifting of tower cylinder and the lifting of blade can synchronously be carried out, and save the set-up time.Hoisting Program two and Hoisting Program three be mainly wind larger time hanging method, these two schemes mainly use headframe type loop wheel machine 200, can reduce cause parts to rock because wind speed brings more greatly or rotate and on the impact of assembling, carrying out smoothly of installation can be guaranteed in hoisting process by the accessory appliances (middle erecting stage 220, tower wound packages join auxiliary device 240, lifting table 400, blade mounting arrangement 410 etc.) on this headframe type loop wheel machine 200.Save the set-up time.
The foregoing is only preferred embodiment of the present invention, protection scope of the present invention is not limited thereto, and anyly all belongs within scope based on the equivalent transformation in technical solution of the present invention.
