Mountain area to be used in, the occasion of transportation inconvenience.The steel tube tower that structure is simple and direct is used in a large number in plains region.Steel tube tower main
Structure is steel pipe, and tower body uses Luo bolt a section for steel pipe connection to be erected.Steel pipe passes through flat board sawing sheet, bent plate, pipe
Body gap is welded, and school port, end are welded with ring flange and the method such as steel tube surface galvanizing by dipping processes.Steel pipe is by curved
Volume processing, becomes pipe by rectangular flat plate buckling.Specific process is the short side direction offer feeding at flat board, along long limit
Direction is bent to a certain degree, and then short side direction continues feeding one segment distance, and the position that long side direction is new is bent again, this
Process is repeated.Respectively two long side directions of rectangular flat plate being made identical processing, two long back gauges of flat board are close,
It is formed with the pipe of opening.Again by opening pressing, by electric welding, two long limits of original flat board are welded into one.Adding of above-mentioned routine
Work method ensures to be formed the shape of steel pipe by the minor face amount of feeding and long limit amount of bow controlling flat board, although pass through numerical control programming
Method controls mechanical movement, but true form still exists error.For joining of the ring flange that ensures steel pipe two ends and couple
Close, after the welding of the gap of steel pipe, also the circularity at steel pipe two ends is checked and shaping, finally could with ring flange assembling and
Welding.The uniformity coefficient of steel pipe holding capacity, along the circularity of length cross-sectional geometry, is had an impact, in particular with electric power by steel pipe
The voltage of transmission is more and more higher, and the height of power tower is also increasing, and the requirement to steel pipe stress-bearing capability is also improving.
Now the intermediate cross-section profile of steel pipe can only be measured diameter by processing method, and pair cross-section profile cannot be measured, i.e. without
