Background technique
With the continuous development of technique steel construction, the moulding for many technique steel construction abnormal-shaped screw bodies gate occur is set
Meter, as shown in Figs. 1-2, special-shaped positioning blanking, roll, make trouble, and required precision is relatively high, need according to requiring to be spliced into
Various moulding.It is had the disadvantage in that in practice of construction
(1) existing production method be by the spiral bottom board of abnormal-shaped screw body, spiral riser and spiral panel one by one setting-out, under
Expect, roll, assembly welding, finally carrying out overall package, work progress is time-consuming, effort, and difficulty of processing is bigger, and outer dimension
It is difficult to be guaranteed.
(2) in the correction of the elongated tube wall ovality of large-scale pipeline, a point of pipeline is corrected, consecutive points are simultaneously
Meeting gradual change, while vertical direction caliber increases, horizontal caliber also can accordingly change, and need real time correction, then tracing detection, so
It corrects again afterwards.Existing detection mode and real time correction matching degree be not high, is not able to satisfy detection, the alternate flexibility of correction, can not
Tube wall is corrected, correction foundation is provided in real time.
(3) on the same axis, installation influences each other, and leads to testing result for pipeline ovality detection device and means for correcting
Error is big, and pipeline center's deviation in construction, radius is caused to be difficult to control；Set of radial pattern support device in horizontal pipe not
It is easily assembled, and pipe diameter is adjusted to support using eyelid retractor inside pipeline, then temporary weld support construction, prevents tube wall
Rebound, causes lot of materials to waste, and increases the manpower consumption of inner wall pad cutting polishing.
(4) in pipeline production construction, pipeline girth welding is conventionally using rotation weldering, i.e., pipeline is placed on positioner, turns
Tire rotation drives pipeline rotation, and welding production process is made to realize automatic displacement, to reduce manual operation intensity, improves production efficiency
And welding quality.Positioner is usually multiple to be applied in combination, and need to be placed on an axis, be adjusted each positioner according to line size
Positioner wheel spacing, height.And some construction sites are narrow, partially have the plane of difference of height that can not utilize.
In consideration of it, need to invent the production method and relative production device of a kind of abnormal-shaped screw body, meet detection, correction,
The installation requirement of difference of height plane positioner improves producing efficiency, guarantees production precision, reduces operation labour difficulty, reduces construction
Cost.

The production method and relative production device of abnormal-shaped screw body of the invention have the advantages that
1, existing production method be by the spiral bottom board of abnormal-shaped screw body, spiral riser and spiral panel one by one setting-out, under
Expect, roll, assembly welding, finally carrying out overall package, work progress is time-consuming, effort, and difficulty of processing is bigger, and outer dimension
It is difficult to be guaranteed.And the technology of the present invention is the tube that is projected out abnormal-shaped screw body as the disjunctor blank of spiral bottom board,
Entire tube is convenient for detection, correction, and is convenient for utilizing the devices auxiliary constructions such as positioner platform.
2, existing detection mode and real time correction matching degree be not high, is not able to satisfy detection, the alternate flexibility of correction, can not
Tube wall is corrected, correction foundation is provided in real time.And a kind of ovality detection device of the present invention, it is set up by the both ends in pipeline
Bracket and central tube, and central tube is located at the center of pipeline, central tube inner sleeve wears cylinder, when to the detection of steel pipe ovality and
The position that rangefinder alignment need to correct is detected, then is corrected using eyelid retractor to tube wall by timing.The zero of rangefinder
Position need to snap on the central axes of pipeline, and reading is avoided to cause error when converting.
3, ovality means for correcting be equipped with center rest, annular seating is supported on central axis first, then by
Step completes the assembling of support rod, connecting rod and eyelid retractor, is in eyelid retractor outer end in circular trace.By adjusting eyelid retractor,
The circular trace can be made gradually to coincide with the inner circle of pipeline.Traditional handicraft is avoided, temporary weld support construction inside pipeline is made
At waste of material, and increase the problem of manpower consumption that the cutting of inner wall pad is polished.
4, compared with prior art, positioner wheel is driven by distance regulating mechanism and adjusts the distance between left and right positioner wheel,
The scope of application of positioner workbench is expanded, the different pipeline of diameter can be suitable for.Positioner wheel height is adjustable,
Construction site is narrow, partially has the plane of difference of height, and in the production of variable diameters pipeline, by positioner works multiple on an axis
Make the positioner wheel spacing of platform, height adjusts one by one.When positioner wheel and tube wall contact, shaft is driven to change angle, it is adaptive to be suitable for
The angle change of variable diameters pipeline.Nozzle axle center is adjusted on a horizontal line, wanting for the vertical basal plane of welding surface can be met
It asks.
