Abstract

The utility model discloses a fitting-up welding correction device of heavy caliber steel pipes. The structure of the fitting-up welding correction device of the heavy caliber steel pipes mainly comprises hydraulic jacks, inner supporting steel pipes, steel pipe seats and a pipe seat plate. The steel pipe seats are welded on the pipe seat plate and shaped like a Chinese character 'mi', one ends of the inner supporting steel pipes are inserted on the steel pipe seats, the other ends of the inner supporting pipes are connected with the hydraulic jacks, and the hydraulic jacks are distributed inside the pipe mouths of heavy caliber steel pipes carrying out fitting-up welding. The pressure of the hydraulic jacks in different positions are adjusted, bended and deformed steel pipe mouths can be corrected as circular pipe mouths with identical roundness conveniently, the fitting-up pipe mouths can be welded together, then the pressure of the hydraulic jacks can be released, and the hydraulic jacks can be moved to a next connector to carry out correction. The fitting-up welding correction device of the heavy caliber steel pipes has the advantages of being simple and reasonable in structure, convenient to use, capable of effectively correcting the problem of bending deformation caused by self-gravity of steel pipes, and not only suitable for the usage of the construction site of the fitting-up welding of the heavy caliber steel pipes, but also suitable for the usage of connecting short pipes into long pipes of a manufacturing factory of the heavy caliber steel pipes in the factory.

Description

Large-diameter steel pipe welding means for correcting
Technical field
The utility model relates to a kind of auxiliary equipment that will become the large-diameter steel pipe welding, particularly can effectively prevent the device that meeting invar pipe perpendicularity and circularity distortion etc. cause the mouth of pipe to misplace in large-diameter steel pipe welding process.
Background technology
In order to ensure large-diameter steel pipe pipeline construction quality, the steel pipe butt joint is an important step in the whole construction, and the quality of welding directly can influence the effect that whole steel pipe is installed, and therefore, the control steel pipe is the most important thing to quality.The steel pipe shell ring is in transportation, lifting and organizing process, owing to influenced by deadweight, particularly reclinate phenomenon can appear in large-diameter steel pipe, and the difference of steel plate material and thickness, crooked degree are also different, as simply support the back welding with straight-bar, make the dislocation of the butt joint mouth of pipe easily, have a strong impact on welding quality, also can make coupling place staggered floor occur, cause the steel pipe roundness variation, may change the internal diameter of steel pipe when serious.Can have a strong impact on the installation quality of large-diameter steel pipeline like this.
Summary of the invention
The purpose of this utility model is present ubiquitous weak point when solving group to large-diameter steel pipe, design a kind of simple and reasonable, easy to use, can effectively solve because the steel pipe self gravitation causes diastrophic large-diameter steel pipe welding means for correcting.
Large-diameter steel pipe welding means for correcting of the present utility model, its structure mainly is made up of hydraulic jack, inner support steel pipe, steel-tube seat, base plate, described steel-tube seat becomes the rice font to be welded on the base plate, one end of inner support steel pipe is inserted on the steel-tube seat, the other end of inner support steel pipe is connected with hydraulic jack, and hydraulic jack is distributed in the large-diameter steel mouth of pipe of welding.
Above-mentioned hydraulic jack and inner support steel pipe are at least 2.Concrete quantity can increase according to the pipe deformation situation, can be scattered in meter font with 8 jack and inner support steel pipe when pipe deformation is serious and be supported in the mouth of pipe that needs welding.
Large-diameter steel pipe welding means for correcting of the present utility model, regulate the pressure of the hydraulic jack of different azimuth, can easily diastrophic flat tube mouth be proofreaied and correct and be the pipe mouth of circularity unanimity, the right mouth of pipe of group can be welded together, discharge the pressure of hydraulic jack then, move to next interface and proofread and correct.Have simple and reasonable, advantage such as easy to use, can effectively proofread and correct because steel pipe causes diastrophic problem because of self gravitation, use the job site that both has been fit to the large-diameter steel pipe welding, and the manufacturer that also is fit to large-diameter steel pipe connects into long tube with short tube and uses in factory.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is another kind of structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing 1 and accompanying drawing 2,1 among the figure is hydraulic jack, the 2nd, and inner support steel pipe, the 3rd, steel-tube seat, the 4th, base plate, the 5th, large-diameter steel pipe.Large-diameter steel pipe welding means for correcting of the present utility model, its structure mainly is made up of hydraulic jack 1, inner support steel pipe 2, steel-tube seat 3, base plate 4,3 one-tenth rice of described steel-tube seat font is welded on the base plate 4, one end of inner support steel pipe 2 is inserted on the steel-tube seat 3, the other end of inner support steel pipe 2 is connected with hydraulic jack 1, and hydraulic jack 1 is distributed in 5 mouthfuls of the large-diameter steel pipes of welding.
Above-mentioned hydraulic jack 1 and inner support steel pipe 2 are at least 2.Concrete quantity can increase according to the distortion situation of large-diameter steel pipe, and large-diameter steel pipe is out of shape and can be scattered in meter font with 8 jack and inner support steel pipe when serious and be supported in the mouth of pipe that needs welding, as shown in Figure 1.When the large-diameter steel pipe distortion was light, also available 4 jack and inner support steel pipe were formed cross being supported in the mouth of pipe that needs welding, as shown in Figure 2.

Claims (2)

1. large-diameter steel pipe welding means for correcting, it is characterized in that comprising hydraulic jack, inner support steel pipe, steel-tube seat, base plate, described steel-tube seat becomes the rice font to be welded on the base plate, one end of inner support steel pipe is inserted on the steel-tube seat, the other end of inner support steel pipe is connected with hydraulic jack, and hydraulic jack is distributed in the large-diameter steel mouth of pipe of welding.
2. large-diameter steel pipe welding means for correcting as claimed in claim 1 is characterized in that described hydraulic jack and inner support steel pipe are at least 2.
