Embodiment 1

[0026] Such as figure 2 , Figure 4 , Figure 5 As shown, the large-diameter steel pipe girth welding support adjustment device in this embodiment includes a support device and an adjustment device. The support device includes a bottom plate 1 and two support plates 2 arranged on the bottom plate 1. Two chucks on crossbar 4.

[0027] In this embodiment, the two support plates 2 are fixed on one set of parallel sides of the bottom plate 1 .

[0028] The collet of this embodiment includes two clamping columns 5 fixed on the cross bar 4. When working, the collet is stuck on the pipe wall of the large-diameter steel pipe, and the large-diameter steel pipe is rolled using the principle of leverage. In order to make the collet It is easier to be stuck on the pipe wall of the large-diameter steel pipe. In this embodiment, two clamping columns 5 are vertically fixed on the cross bar 4, and the two clamping columns 5 are parallel to each other at the same time.

[0029] The method...

Embodiment 2

[0036] Such as image 3 , Figure 4 , Figure 6 As shown, this embodiment is basically the same as Embodiment 1, the difference is that the two support plates 2 of this embodiment are respectively provided with a number of rollers 3, and the rollers 3 can rotate freely. In order to make the force more uniform, the transmission efficiency More preferably, in this embodiment, the rollers 3 are arranged on the support plate 2 at equal intervals.

[0037] After the roller 3 is added to the support plate 2, the large-diameter steel pipe changes from sliding friction to rolling friction during the rolling process, which greatly reduces the difficulty of rolling the large-diameter steel pipe, and also reduces the possible noise. More comfortable.

Abstract

The invention discloses a supporting and adjusting device for circular seam welding of large-diameter steel pipes and a welding implementation method. The supporting and adjusting device comprises a supporting device and an adjusting device, the supporting device comprises a bottom plate (1) and two supporting plates (2) arranged on the bottom plate (1), the adjusting device comprises a cross rod (4) and two clamping heads arranged on the cross rod (4), and a plurality of rollers (3) are arranged on each of the two supporting plates (2) and are distributed on the same at equal intervals. By the aid of the structure and the method, butting circular seam welding efficiency of the large-diameter steel pipes can be higher, operation can be safer, and welding quality is guaranteed more effectively.

Description

technical field [0001] The invention relates to the fields of building construction and steel pipe welding, in particular to a large-diameter steel pipe circular seam welding support adjustment device and a method for realizing welding. Background technique [0002] Large-diameter steel pipes are mainly used in tap water, natural gas, petroleum, marine and other engineering fields, and their diameters are generally above 2000mm. A long large-diameter steel pipe is welded by butt ring seams of several short large-diameter steel pipes, and this short large-diameter steel pipe is welded by bending a steel plate or steel strip into a cylindrical shape . Such as figure 1 As shown in the figure, place the two sections of large-diameter steel pipes to be connected on the H-shaped steel through the lifting device. The H-shaped steel is used as the supporting device, and then the circular seam welding starts. For the welding position at a lower position, it can be welded directly o...
