Through retrieval, find following close patented technology:
A kind of single arc mariages method for welding pipeline (CN102615395A), belong to the oil and gas pipes welding technology field.Described method comprises: the pipe end to two pipelines to be welded carries out respectively groove processing, and realizes the counterpart to two tube groove places by the counterpart function of internal welding machine; The welding job parameter of internal welding machine and single arc mariages pipeline all-position auto-welding machine is set; More than pipe end preheating to 50 to be welded ℃, utilize internal welding machine to treat the welded tube mouth and carry out root bead; The mouth of pipe after utilizing single arc mariages pipeline all-position auto-welding machine to root bead, carry out respectively from the inside to the outside hot weld, fill weldering and cosmetic welding, until the circumferential surface of weld seam is not less than the pipeline outer wall surface; Filling is welded with multilayer, and the filling welding and assembling height of every layer is not less than 4mm.Single arc mariages method for welding pipeline provided by the invention, can improve the welding efficiency of heavy caliber thick wall pipeline effectively, and have that the welding deposition rate is large, speed of welding is fast, heat input is little, heat affected area is stable and the weld properties advantages of higher.
A kind of mouth of pipe external clamp (CN202517236U) for the long distance pipeline welding, comprise two half-ring trim rings, described two half-ring trim rings form a whole annulus, two respective ends are arranged, one end is the hinged end connected by bearing pin, and the other end is the locking end be connected with hanging sleeve by jack; On each half-ring trim ring, be equipped with at least three foundary weight that are disposed radially, all described foundary weight are uniformly distributed on whole annulus, and the pressure connection terminal of described foundary weight stretches out the inner circle of described half-ring trim ring; Be in the end of described two half-ring trim rings of described locking end, one is provided with hook, and another is provided with jack base, on described jack base, jack is installed, and is connected with hanging sleeve on the push rod of described jack and described hook.The present invention is easy to use, high efficiency, to the mouth of pipe group that is in complex-terrain to same applicable, the group that can greatly heighten the mouth of pipe to quality, save material cost, increase economic efficiency.
Through contrast, present patent application and above-mentioned published patented technology exist and add big difference.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of simple in structure, easy to operate, diverse in function, circular spherical tank counterpart adjusting device that the counterpart accuracy is high are provided.
The present invention solves its technical problem and takes following technical scheme to realize:
A kind of circular spherical tank counterpart adjusting device, it is characterized in that: comprise steel pipe, fixedly ear, conical wedge nail, link, limiting plate, four prismatic chocks and lateral adjustments wedge, all symmetric points are welded with a fixing ear on steel pipe seam both sides outer wall to be welded, fixedly on ear, all be shaped with a vertical through hole, vertically in through hole, regulate a conical wedge nail is installed; These two conical wedges nail on equal horizontal set a link, and these two link lower ends are fixed with a limiting plate jointly; Between the outer wall of steel pipe of described limiting plate and a side, be embedded with one or four prismatic chocks.
And the limiting plate of the link inboard of the horizontal both sides of described fixedly ear is shaped with the adjusting groove, be embedded with for the lateral adjustments wedge in this adjusting groove.
And described steel pipe is conical tube or cylindrical tube.
Advantage of the present invention and good effect are:
1, the inner supporting structure of this device can be used for the steel pipe aligning welding, and solder joint is little, and service speed is fast, causes crator less to outer wall of steel pipe, improves effect.
2, this device can be realized traditional welding operation, and can realize the deformation adjustment of multiple directions.
3, design science of the present invention, simple in structure, reliability is high, and equipment operating is convenient, diverse in function, and moderating force is large, promote process velocity, improve crudy and efficiency, can regulate the steel pipe multiple directions, the tune type is effective, and machining accuracy is high.
The accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is the top view of Fig. 1;
Fig. 3 be in Fig. 1 A-A to schematic cross-section.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of circular spherical tank counterpart adjusting device, comprise steel pipe 7, fixedly ear 4, conical wedge nail 2, link 5, limiting plate 6, four prismatic chocks 3 and lateral adjustments wedge 1, all symmetric points are welded with a fixing ear on steel pipe seam to be welded 8 both sides outer walls, fixedly on ear, all be shaped with a vertical through hole, vertically in through hole, regulate a conical wedge nail is installed; These two conical wedges nail on equal horizontal set a link, and these two link lower ends are fixed with a limiting plate jointly, and this limiting plate Level tune is installed, and these two conical wedge nails are regulated the distance between limiting plate and outer wall of steel pipe; Between the outer wall of steel pipe of described limiting plate and a side, be embedded with one or four prismatic chocks, can regulate spacing between limiting plate and outer wall of steel pipe by regulating this four prismatics chock, thereby regulate the radial dimension of steel pipe walls.
