Embodiment 1

[0042] refer to figure 1, for the present invention discloses a pipe brace corrector, including an upper arc-shaped plate 2 and a lower arc-shaped plate 3 placed in the inner cavity of a curved straightening tube 8, and the radians of the upper arc-shaped plate 2 and the lower arc-shaped plate 3 Similarly, the upper curved plate 2 and the lower curved plate 3 are detachably connected with a length-adjustable top handle 1, and the two ends of the top handle 1 are respectively detachably connected with the upper curved plate 2 and the lower curved plate 3 .

[0043] refer to figure 2 The inner side of the upper arc-shaped plate 2 is welded with an upper reinforcing plate 21, the thickness direction of the upper reinforcing plate 21 is parallel to the axial direction of the upper arc-shaped plate 2, and one side of the upper reinforcing plate 21 is matched with the inner surface of the upper arc-shaped plate 2. The arc surface, the other side of the upper reinforcing plate 21 ...

Embodiment 2

[0060] refer to figure 1 , a pipe brace straightening device, the difference from Embodiment 1 is that the jacking 1 includes an outer tube 11 and an inner rod 12 connected to one end of the outer tube 11, and the outer tube 11 is provided with a drive to drive the inner rod 12 along the The stretching mechanism 13 that moves in the axial direction of the outer tube 11 is provided with an external thread on the outside of the outer tube 11. The stretching mechanism 13 includes a drive screw sleeve fixed on the inner rod 12. The drive screw sleeve is sleeved on the inner rod 12 and connected to the inner The fixing ring that rod 12 is fixed has a screw sleeve integrally formed on the fixing ring, the inner surface of the screw sleeve is provided with an internal thread that cooperates with the outer tube 11, and the outer side of the screw sleeve is integrally formed with a hexagonal ring, and the transmission screw sleeve is threadedly connected with the outer tube 11. One end...

Abstract

The invention discloses a pipe supporting opening corrector. The pipe supporting opening corrector comprises an upper arc-shaped plate and a lower arc-shaped plate. A length-adjustable jacking rod isdetachably connected between the upper arc-shaped plate and the lower arc-shaped plate. The two ends of the jacking rod are detachably connected with the upper arc-shaped plate and the lower arc-shaped plate correspondingly. A limiting mechanism for limiting back movement of the upper arc-shaped plate and the lower arc-shaped plate is detachably connected between the upper arc-shaped plate and thelower arc-shaped plate. The pipe supporting opening corrector has the advantages that the maximum distance between an upper arc-shaped panel and a lower arc-shaped panel is limited, and excessive pipeline correction is reduced.

Description

technical field [0001] The invention relates to the field of pipe straightening tooling, in particular to a pipe brace straightening device. Background technique [0002] Pipeline engineering is gradually favored due to its advantages in energy saving, cost, and environment. Pipelines are developing in the direction of long distances, large diameters, and high strength. When large-diameter steel pipes are hoisted, improper hoisting methods can easily lead to deformation of the nozzle, which affects the quality of butt welding of the pipe and the construction speed. In construction, methods such as cutting pipe heads or flame heating recovery are generally adopted, which not only wastes materials but also increases costs. Some high-strength pipes are not allowed to adopt flame heating recovery to ensure their own strength. [0003] The Chinese invention patent whose authorized notification number is CN203695661U discloses a kind of pipe nozzle jack correction tooling, which ...
