The fit-up rotator consists of a set of hydraulic lifting rotator
(2 units)and a set of travelling welding rotator (2 units).The four
cylinders of the hydraulic lifting rotator are used to
telescopically control the distance between the centers of the four
rollers,to change the upper tower displacement in the height
direction and the horizontal direction,so as to completely fit with
the tower placed on the traveling welding rotator,and the rotation
of the traveling welding rotator drives the rotation of the two
towers sections,so that the tower group is completed synchronously
fit.The welding is completed on the automatic welding equipment to
complete the pair welding of the entire tower body. Below are the relevant parameters for different models | Model | Max loading(kg) | Applied job dia(mm) | Roller dia &width(mm) | Wheel linear speed(mm/min) | | GK-20-F | 2000 | θ1500-4000 | θ350*150 | 100-1000mm/min | | GK-40-F | 4000 | θ2000-4500 | θ400*160 | 100-1000mm/min | | GK-60-F | 60000 | θ2500-5000 | θ450*180 | 100-1000mm/min | | GK-80-F | 80000 | θ2800-5500 | θ500*200 | 100-1000mm/min | | GK-100-F | 100000 | θ3000-6500 | θ500*220 | 100-1000mm/min |
The growing line is composed by one set of fix type hydraulic
fit-up rotator and one set of movable adjustable rotator.
The wind tower body is fit-up and welded at this working station.
The first section is placed on the adjustable rotator, the second
is put on the hydraulic fit up rotator. After align the two
section, by adjusting fit up rotator, spot welding is done by
rotate the adjustable rotator. The manipulator complete outside and
inside circular welding after fit up. Steps by steps, the sections
is connected and grow to the whole line, until the last section
with flange is welded. - 1st step, put the section with flange on one set of rotator
- 2nd step, put the second section on the fit up rotator, do spot
welding by adjust the fit up rotator.
- 3rd, Welding manipulator finish inside circular welding.
- 4th, move the adjustable rotator to pull the section backward.
- 5th , put the third section on the fit up rotator.
- 6th, do spot welding by adjusting the fit up rotator.
- 7th , welding manipulator finish inside circular welding.
- 8th , the adjustable rotator move backwards together with the tower
body.
- 9th, put the fourth section on fit up rotator
- 10th, spot welding done by adjusting fit up rotator
- 11th, welding manipulator finish inside circular welding.Repeat
above steps until the last section with flange is fit up.
- 12th , the movable manipulator do all outside circular welding.
- Put The Second Section On The Fit Up Rotator, Do Spot Welding By
Adjust The Fit Up Rotator.
- Do Spot Welding By Adjusting The Fit Up Rotator.
- Spot Welding Done By Adjusting Fit Up Rotator
