The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the utility model can be implemented according to the multitude of different ways that claim limits and covers.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of large-diameter pipeline group is to device, it comprises jacking apparatus 9, guide groove positioning device 6 positioners, guide groove positioning device 6 positioners are installed on the bore front end of pipeline, jacking apparatus 9 is comprised of jack 5 and the curved plate 4 that is welded on the jack 5, and curved plate 4 has the radius of curvature identical with the pipeline radius.During use, with rear end steel pipe 8 jack-up slowly, by jack move left and right rear end steel pipe 8, rear end steel pipe 8 is alignd substantially with jacking apparatus 9 with front end steel pipe 7 horizontal directions, vertical direction rear end steel pipe 8 exceeds about 5cm than front end steel pipe 7; Then adopt jack that rear end steel pipe 8 is imported in the guide groove positioning device 6 of front end steel pipe 7, with jacking apparatus 9 rear end steel pipe 8 is slowly fallen, adopt simultaneously the position, the left and right sides of jack control rear end steel pipe 8, pipeline enter the guide groove positioning device 6 of front end steel pipe 7 interior after, adopt jack with further distance with front end steel pipe 7 of rear end steel pipe 8, satisfy the requirement of welding counterpart width, arrive pipeline and accurately organize centering.By jacking apparatus 9 rear end steel pipe 8 is imported in the guide groove positioning device 6 of front end steel pipe 7, simplified operating procedure, by the accurate control of guide groove positioning device 6, steel pipe has guaranteed that with front end steel pipe 7 the adjacent channel tube wall is concordant before and after having guaranteed, has guaranteed the welding quality of pipe welding port.
Generally speaking, guide groove positioning device 6 is at least two guide grooves, three guide grooves wherein is installed is saved the most material.Find that through experiment the most fixing when guide groove is following two kinds of modes, effect is best: the one, guide groove is long 50mm, wide is the triangle angle steel of 5mm, is welded on the pipeline front end; The 2nd, be the rectangle steel plate of 400mm for long, wherein 200mm is welded on the pipeline front end, and 200mm is unsettled.
