A kind of submerged arc welding device of large-sized annular composite welds
Technical field
The utility model relates to welding technology field, particularly a kind of submerged arc welding device of large-sized annular composite welds.
Background technology
At present, China is greatly developing Wind Power Generation Industry, and wind power tower foundation ring is generally formed by upper flange 1-1, cylindrical shell 1-2 and lower flange 1-3 welding, as shown in Figure 1.The weld seam of cylindrical shell 1-2 and lower flange 1-3 is ring-shaped combination weld seam, has 60 ° of angles, as shown in Figure 2.If employing gas guarantor welds, efficiency is relatively low, cannot be to positive bevel center if adopt common submerged arc welding device to weld welding wire, and appearance of weld is poor, and can not guarantee weldquality.
Utility model content
Goal of the invention of the present utility model is: especially for the difficult point in wind-powered electricity generation foundation ring and the manufacture of similar workpiece, a kind of submerged arc welding device of large-sized annular composite welds is provided, can overcome the position limitation of large-sized annular composite welds welding, the easy welding that realizes ring-shaped combination weld seam, welding operation is safe and reliable, labour intensity reduces, and welding quality effectively guaranteed, production efficiency is improved significantly.
The technical solution adopted in the utility model is such:
A kind of submerged arc welding device of large-sized annular composite welds, comprise mass-type foundation plate, on mass-type foundation plate, be fixedly installed turning rolls base, the long roller rack of short roller rack and both sides thereof, domatic and the mass-type foundation plate of described turning rolls base becomes 30 ° of angles, described long roller rack becomes 60 ° of angles vertical with turning rolls base with the domatic coplanar of short roller rack and with mass-type foundation plate, on described turning rolls base domatic, be fixedly installed return idler frame and active roller frame and the two corresponding center of circle line overlaps, on described short roller rack domatic, be fixedly installed the domatic vertical short carrying roller with turning rolls base, described two long roller racks domatic upper arranges respectively a long carrying roller, long carrying roller one end is hinged, the other end is slidably connected in arc chute that long carrying roller hinged end is the center of circle, two long carrying rollers and short carrying roller point to the corresponding center of circle of return idler frame line jointly.
The domatic angle setting of described turning rolls base, long roller rack, short roller rack, can so that the composite welds angle of foundation ring placed thereon bottom towards in vertical, thereby be conducive to coordinate common cantilever submarine arc-welding machine to carry out the welding of composite welds.
Long carrying roller can rotate on long roller rack, to adapt to foundation ring and the similar ring device of different-diameter.
As preferably, described active roller frame is more domatic than the more close short roller rack of return idler frame.The order of drive roll wheel carrier and return idler frame, can adjust according to the shape of foundation ring to be welded, is not limited in above-mentioned optimal way.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: by foundation ring slant setting to be welded, make sealing to be welded just in time in plumb position, thereby coordinate easily cantilever submarine arc-welding machine to weld; Short carrying roller, a center of circle of the common sensing of long carrying roller can be rotated easily foundation ring to be welded on this device.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment:
As shown in Figure 3,4, a kind of submerged arc welding device of large-sized annular composite welds, comprises mass-type foundation plate 1, is fixedly installed the long roller rack 7 of turning rolls base 2, short roller rack 5 and both sides thereof on mass-type foundation plate 1.
1 one-tenth 30 ° of angle of domatic and mass-type foundation plate of described turning rolls base 2, described long roller rack 7 and the domatic coplanar of short roller rack 5 and with 1 one-tenth 60 ° of angle vertical with turning rolls base 2 of mass-type foundation plate, on described turning rolls base 2 domatic, be fixedly installed return idler frame 3 and active roller frame 4 and the two corresponding center of circle line overlaps, on described short roller rack 5 domatic, be fixedly installed the domatic vertical short carrying roller 6 with turning rolls base 2.
Described two long roller racks 7 domatic upper arranges respectively a long carrying roller 8, long carrying roller 8 one end are hinged, the other end is slidably connected in arc chute 7-1 that long carrying roller 8 hinged ends are the center of circle, two long carrying rollers 8 and the common return idler frame 3 corresponding center of circle lines that point to of short carrying roller 6.
Described active roller frame 4 is more domatic than the more close short roller rack 5 of return idler frame 3.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
