The method for carrying out electric power tower steel pipe circular section contour detecting using averaging method
Technical field
It is especially a kind of to carry out electric power tower using averaging method the present invention relates to a kind of detection method of electric device
The method of steel pipe circular section contour detecting.
Background technology
Power Transmission process needs the electric power tower largely used, electric power tower subangle head tower and steel tube tower.Angle steel tower master
To be used in mountain area, the occasion of communications and transportation inconvenience.In the steel tube tower that plains region largely uses structure simple and direct.Steel tube tower it is main
Structure is steel pipe, and tower body is erected a section connection of steel pipe using bolt.Steel pipe passes through tablet sawing sheet, bent plate, pipe
Body gap is welded, and school port, end and the methods of ring flange welding and steel tube surface galvanizing by dipping are process.Steel pipe passes through curved
Volume processing, by rectangular flat plate buckling at pipe.Specific process is the short side direction offer feeding in tablet, along long side
Direction is bent to a certain degree, and then short side direction continues to feed a distance, and the new position of long side direction is bent again, this
Process is repeated.Identical processing is made to two long side directions of rectangular flat plate respectively, two long back gauges of tablet are close,
It is formed with the pipe of opening.Opening is pressed again, two long sides of original tablet are welded into one by being welded.Above-mentioned conventional adds
Work method to form the shape of steel pipe by the short side amount of feeding and long side amount of bow for controlling tablet to ensure, although passing through numerical control programming
Method control machinery moves, but true form still has error.In order to ensure matching for steel pipe both ends and the ring flange that couples
Close, after the welding of the gap of steel pipe, also the circularity at steel pipe both ends is carried out checking and shaping, could finally be assembled with ring flange and
Welding.Steel pipe has an impact the uniformity coefficient of steel pipe endurance, along the circularity of length cross-sectional geometry in particular with electric power
The voltage of transmission is higher and higher, and the height of power tower is also increasing, and the requirement to steel pipe stress-bearing capability is also improving.
Present processing method can only measure diameter to the intermediate cross-section profile of steel pipe, and pair cross-section profile is unable to measure, i.e., without
Method knows practical circular section profile and designs the error size of circular section profile.
Invention content
