Specific embodiment
Below in conjunction with embodiment of the present invention, the technical solution in embodiment of the present invention is carried out clearly and completely
Description, it is clear that described embodiment is only some embodiments of the invention, rather than whole embodiments.Base
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all
Other embodiments shall fall within the protection scope of the present invention.
As shown in Figure 1, in conjunction with Fig. 2, power transmission steel pipe tower of the invention, including steel pipe 1, ring flange 2 and gusset 3, wherein steel
Pipe 1 is formed by connecting by 4N 11 head and the tail of side plate of same size, and 1 cross section of steel pipe is in the side 4N shape, and gusset 3 is provided with 4N, often
A gusset 3 is mutually perpendicular to and is welded and fixed with 1 side plate 11 of steel pipe and 2 surface of ring flange, and steel pipe 1 is mutually perpendicular to and welds with blue disk 2
Fixation is connect, N is positive integer.In the present embodiment, N is equal to 3, i.e. 1 cross section of steel pipe is in 12 side shapes.Specifically, the steel pipe 1 can
With by monolithic steel plate bending at being welded from beginning to end after each side plate 11, can also be by several pieces of steel plate bendings at head and the tail after side plate 11
It is welded, naturally it is also possible to be welded by 4N individual 11 head and the tail of side plate.
Wherein, the power transmission steel pipe tower flange welding technique the following steps are included:
Gusset 3 is first arranged in a mutually vertical manner and is welded and fixed with steel pipe 1 and 2 surface of ring flange by S1.Specifically, can adopt
It is fixed with the mode of spot welding, is convenient for next weld seam welding.
Weld seam and 1 bottom outer wall of steel pipe and ring flange 2 between S2, then 1 bottom interior wall of welded still pipe and ring flange 2
Between weld seam.Specifically, as shown in figure 3, step S2 includes,
S2-1, the prime coat between first 1 bottom interior wall of welded still pipe and ring flange 2；
Prime coat between S2-2, then 1 bottom outer wall of welded still pipe and ring flange 2；
Filled layer between S2-3, then 1 bottom interior wall of welded still pipe and ring flange 2；
Filled layer between S2-4, then 1 bottom outer wall of welded still pipe and ring flange 2；
S2-5, the capping layer between last 1 bottom interior wall of welded still pipe and ring flange 2；
Capping layer between S2-6, then 1 bottom outer wall of welded still pipe and ring flange 2.
Specifically, the step S2-1 and S2-2, step S2-3 and S2-4, step S2-5 and S2-6 welding simultaneously.In this way,
It can prevent steel pipe 1 and 2 commissure of ring flange from being cooled down by heating repeatedly, prevent stress from generating, welding efficiency is higher.Based on same
Consider, the step S2-1 and S2-2 welding direction is identical, and step S2-3 and S2-4 welding direction is identical, step S2-5 and S2-6
Welding direction is identical.So symmetrical welding manner, can substantially reduce the stress of commissure.
S3, as shown in figure 4, in conjunction with Fig. 5,2 surface segmentation of ring flange is 4N section by 4N gusset 3, according to executing step
Welding direction when rapid S2 is sequentially completed the steel pipe 1 in each section and the welding of 2 weld seam of ring flange clockwise or counter-clockwise.
In this way, only welding need to can be completed clockwise or counter-clockwise by one circle of steel pipe 1 and the rotation of ring flange 2, it is more efficient.Steel pipe 1
Often larger with 2 volume of ring flange, heat conduction efficiency is higher, executes again after completing two weld seams in a section next
Weld seam welding in section, tends not to generate biggish stress.Of course, for the steel pipe 1 and ring flange 2 of small volume,
Two weld seams welding in a section by the way of symmetrical welding, i.e., can also be first completed, then executes two of symmetric interval
Weld seam welding, reduces welding stress.
S4 is divided into two groups, two 11 phases of side plate in each group as shown in figure 5, choosing four side plates 11 on steel pipe 1
Mutually parallel, the side plate 11 between two groups is vertical, and 11 corresponding four gussets 3 of this four side plates are welded in the following order
It connects: first will wherein be welded with side plate 11 and 2 surface of ring flange a gusset 3, i.e. step S4-1；Again by the other muscle in same group
Plate 3 and side plate 11 and 2 surface of ring flange are welded, i.e. step S4-2；Again by the gusset 3 and side plate 11 and ring flange in another group
The welding of 2 surfaces, i.e. step S4-3；Another gusset 3 in another group is welded with side plate 11 and 2 surface of ring flange finally, that is, is walked
Rapid S4-4.In this way, can effectively reduce welding stress by the way of cross welding, positioning is more accurate, prevents from being partially welded, and
It can prevent weld seam from cracking failure occurs in later period use process.
Specifically, as shown in fig. 6, forming two balanced weldings in left and right between each gusset 3 and side plate 11 and 2 surface of ring flange
It stitches, the welding of the two symmetrical weld seams in left and right includes the following steps,
The prime coat of a wherein weld seam is first welded, then welds the prime coat of an other weld seam, i.e. step S4a；
The filled layer of first weld seam is welded again, then welds the filled layer of an other weld seam, i.e. step S4b；
The capping layer of first weld seam is finally welded, then welds the capping layer of an other weld seam, i.e. step S4c.
In this way, can prevent from being cooled down at gusset 3 and 2 surface weld of side plate 11 and ring flange by heating repeatedly, prevent stress from producing
Raw, welding efficiency is higher.Based on same consideration, the welding direction of every one of weld seam of the two symmetrical weld seams in left and right is identical.Such as
This symmetrical welding manner can substantially reduce the stress of commissure.
S5 is sequentially completed the weldering of 4N gusset 3 Yu side plate 11 and ring flange (2) surface according to the welding sequence of step S4
It connects.
The foregoing is merely better embodiments of the invention, are not intended to limit the invention, all of the invention
Within spirit and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
