Description
Technical field
The application is related to a kind of verifying attachment, particularly a kind of electric power tower steel pipe circular section contour detecting device.
Background technology
Power Transmission process needs a large amount of electric power tower, electric power tower subangle head tower and steel tube towers using.Angle steel tower main
Mountain area to be used in, the occasion of communications and transportation inconvenience.In plains region in a large number using the steel tube tower that structure is simple and direct.Steel tube tower main
Structure is steel pipe, and a section for steel pipe connection is erected by tower body using Luo bolt.Steel pipe passes through flat board sawing sheet, bent plate, pipe
Body gap is welded, and school port, end and the method such as ring flange welding and steel tube surface galvanizing by dipping process.Steel pipe passes through curved
Volume processing, rectangular flat plate buckling is become pipe.Specific process is the short side direction offer feeding in flat board, along long side
Direction is bent to a certain degree, and then short side direction continues feeding one segment distance, and the new position of long side direction is bent again, this
Process is repeated.Respectively two long side directions of rectangular flat plate are made with identical processing, two long back gauges of flat board are close,
It is formed with the pipe of opening.Again opening is pressed, by electric welding, the two of original flat board long sides are welded into one.Above-mentioned conventional adding
Work method to ensure to form the shape of steel pipe although passing through numerical control programming by the minor face amount of feeding and long side amount of bow controlling flat board
Method control machinery is moved, but true form still has error.In order to ensure steel pipe two ends and the joining of the ring flange coupling
Close, after the welding of the gap of steel pipe, also the circularity at steel pipe two ends will be checked and shaping, finally could with ring flange assembling and
Welding.Steel pipe, along the circularity of length cross-sectional geometry, has an impact to the uniformity coefficient of steel pipe endurance, in particular with electric power
The voltage more and more higher of transmission, the height of power tower is also increasing, and the requirement to steel pipe stress-bearing capability is also improving.
The Chinese utility model patent application of Application No. 201320308336.5 disclosed in 11 days December in 2013, its
Entitled " the electric power tower aligning device for steel tube " of bright creation, it includes base, the first column perpendicular to base and second and stands
Post, there are semi-circular recesses described first column upper end, and groove radius are more than the steel pipe radius needing straightening, and described second stands
One circular hole is arranged at post top, circle hole radius be more than need straightening steel pipe radius it is characterised in that: also include one and be fixed on bottom
Support on seat, one end of this support is provided with hydraulic cylinder, and the free end of the piston rod of this hydraulic cylinder connects an arc pressuring plate,
This plate shape pressing plate is corresponding with the semi-circular recesses on the first column.Also include the first collateral fagging and the second collateral fagging,
First collateral fagging and the second collateral fagging are connected with base respectively, and the first collateral fagging and the second collateral fagging intersect in x
Shape.During use, one end of steel pipe is inserted in the circular hole of the second column and is positioned, the crooked position of steel pipe is positioned over
In the semi-circular recesses of the first column, crooked position upwards, starts hydraulic cylinder, and the piston driving arc pressuring plate of hydraulic cylinder moves down,
The bend of steel pipe is pressed into flat by plate shape pressing plate.Thus structure is simple, using angle steel or the steel pipe of bending, make to be manufactured into electricity
The angle steel of power steel tower or steel pipe are required to there is good glacing flatness.
For above-mentioned steel tower steel pipe, we need, in advance or after straightening process, glacing flatness to be detected.Processing side now
Method can only measure diameter to the intermediate cross-section profile of steel pipe, and pair cross-section profile cannot measure, and cannot know actual circular section wheel
The wide error size with design circular section profile.
The Chinese invention patent application of Application No. 201110069188.1 disclosed in 26 days October in 2011, its invention wound
Entitled " the steel pipe circular section contour detecting device of steel tube tower of power tower and its detection method " made, it is including opening
Clamp block, measurement base and measurement arm, connect measurement base wherein in opening clamp block, measurement base is connected with each other with measurement arm again；
Whole device is fixed on steel pipe to be measured opening clamp block；Ring-shaped guide rail is provided with measurement base, measurement arm is led along annular

Slightly larger than 120 degree；4) position sensor on measurement arm is used for detecting the position of initial point, terminal and several intermediate marker blocks,
Thus learning the angular position information in three range sensor each leisure measurement process on measurement arm, range sensor can detect
Obtain measurement head to the distance of steel tube surface；5) when the limited block on measurement arm is from initial point block, arrive to position sensor
During reaching initial point flag bit, range sensor obtains the information of former and later two sensor head and the tail overlay segments；When position sensor exists
Move between initial point attribute block and post block, range sensor obtains each effective information away from steel pipe measurement surface；When
Position sensor moves between post block to limited block to terminal block, and it is steel pipe distance that range sensor obtains again
Overlay information；It is in the middle of the information of each measurement head gained, to have 120 degree of effective informations being steel pipe profile, have from beginning to end and respectively have one section
For overlay information；Overlay information is used for data processing, and 120 degree of information that three range sensors are recorded respectively synthesize to be measured
The information of 360 degree of dimension pipe profile, therefore simulates the contour curve of Tube heating furnace position to be measured, completes to steel pipe to be measured
Contour detecting.
Above-mentioned patent application is although can measure to the circular section profile of steel tower steel pipe, however, having as follows not
Foot:
1. three position sensor detection datas have overlap, are not easy to differentiate.
2. an iron rake with three to six teeth steel pipe is fixing difficult, needs manually installed fixation, and steel tower steel pipe axial length is long, will be vertical for steel tower steel pipe
