The specific embodiment
As Fig. 1, Fig. 2, convex structure steelframe 2 adopts the gate-type structure, mainly bears job platform and the supporting role of steel pipe weight transmitting; The movement support structures group is furnished with 6 groups altogether, and the control of 6 oil cylinders is arranged respectively, opens supporting steel pipe successively according to each stage that steel pipe rolls, and makes steel pipe by set track roll-forming, and each support group strong point disperses, and avoids local support to influence steel pipe roundness.Each strong point all adopts to roll and supports, and plays guide effect in simultaneously steel plate being rolled, and prevents that steel pipe from rolling the medial end portions sideslip.The process of rolling is achieved in that the steel plate that butt joint is finished is transported to veneer reeling machine 1 and begins to roll, along with rolling of veneer reeling machine, the curved rising of steel plate (circle shown in dotted lines in Figure 1), the oil cylinder of handling on the right supporting construction 4 10 by hydraulic system makes it to rise and withstand on the steel plate exterior arc surface; Steel plate continues to roll and rise, and leading section is during to the right side central position, and the oil cylinder of handling on the right supporting construction 39 by hydraulic system makes it to withstand on the steel plate exterior arc surface, and the control steel pipe rolls radian; When steel plate rises to the upper right quarter position under veneer reeling machine 1 effect, prop up and be supported on the steel plate inwall by right supporting construction 28 of HYDRAULIC CONTROL SYSTEM and right supporting construction 1 respectively, make steel plate continue to move by arc track; When steel plate moves to the upper left quarter position, prop up and be supported on the steel plate inwall by HYDRAULIC CONTROL SYSTEM left side supporting construction 1 and left supporting construction 23, steel plate continues operation; Dock when the termination moves to original position and close up, submerged arc welding machine carries out inboard longitudinal seam welding, after finishing, under the effect of veneer reeling machine 1, makes the steel pipe seam position move to welded top platform 6 positions, submerged arc welding machine welding outside longitudinal joint; After finishing, steel pipe continues operation and proofreaies and correct circularity under the driving of veneer reeling machine 1, unclamp each supporting construction successively by the HYDRAULIC CONTROL SYSTEM oil cylinder then, finishes the operation that rolls of single-unit steel pipe.
Fig. 3-Fig. 5 is the structural representation of left supporting construction 1, and under the promotion of oil cylinder 511, rolling wheel support 501 is boosted, and four rolling 502,503,504,505 withstands on the inwall of steel pipe, finishes the rolling of steel pipe is supported; After support part was finished, oil cylinder 511 retractions drove rolling wheel support 501 and move down, thereby finish support part.
Fig. 6-Fig. 8 is the structural representation of left supporting construction 23, and under the promotion of oil cylinder 311, rolling wheel support 301 is boosted, and four rolling 302,303,304,305 withstands on the inwall of steel pipe, finishes the rolling of steel pipe is supported; After support part was finished, oil cylinder 311 retractions drove rolling wheel support 301 and move down, thereby finish support part.
Fig. 9 Figure 10 is right supporting construction 39 structural representations, and under the promotion of oil cylinder 908, carrying roller 905,906 is moved to the left, and withstands on the outside of steel pipe, finishes the rolling of steel pipe is supported and guiding; After support part was finished, oil cylinder 908 retractions drove carrying roller 905,906 and move right, thereby finished to support and the guiding action.
Figure 11-Figure 13 is right supporting construction 4 10 structural representations, and under the promotion of oil cylinder 1011, rolling wheel support 1001 is boosted, and four rolling 1002,1003,1004,1005 withstands on the outer wall of steel pipe, finishes the rolling of steel pipe is supported; After support part was finished, oil cylinder 1011 retractions drove rolling wheel support 1001 and move down, thereby finish support part.
Because right supporting construction 1 is identical with structure, effect and the course of work of left supporting construction 1, and the installation site symmetry, so the structure of right supporting construction one and the course of work repeat no more.
Because right supporting construction 28 is identical with structure, effect and the course of work of left supporting construction 23, and the installation site symmetry, so the structure of right supporting construction two and the course of work repeat no more.
