Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe correction, in particular to a pipe orifice correction device for a large-diameter thin-walled steel pipe. Background Art

[0002] When large-diameter thin-walled steel pipes are transported, stored and hoisted, the pipe ends are easily squeezed, causing deformation of the pipe ends. In the existing technology, long metal rods are often used to support the pipe ends, and the metal rods and the inner wall of the steel pipe are fixed by welding before transportation. The metal rods are very troublesome to install and disassemble. Moreover, due to the thin wall of the steel pipe, the welding position of the metal rods and the steel pipe wall is easy to cause damage to the steel pipe wall during welding and disassembly.

[0003] In the patent with publication number CN219688047U, a steel pipe mouth protection device is proposed, which includes a center plate, a telescopic rod, a mouth guard plate, a rubber pad, a rod barrel, a rod body, a limit block, a limit ring, a bolt, a pad, and an end-tightening mouth guard plate 3, so that the steel pipe mouth can always maintain its original shape during transportation and lifting, and will not deform after being subjected to force. The steel pipe mouth is supported and limited by multiple groups of telescopic rods 2 and mouth guard plates 3, and multiple telescopic rods 2 are connected by the center plate 3. The mouth guard plate 3 is L-shaped with the outer end bent upward. After installation, the end of the steel pipe mouth is tightly pressed against the inner side of the bent end of the mouth guard plate 3, and the inner wall of the steel pipe mouth is tightly pressed against the upper end surface of the mouth guard plate 3. The position of the guard plate 3 can be positioned and limited. The upper end surface of the guard plate 3 is an arc surface that can completely fit the inner wall of the steel pipe. A slot is provided at one end of the telescopic rod 2 facing the center plate 1. The center plate 1 is a circular plate structure. The outer periphery of the center plate 1 is embedded in the slot at one end of the telescopic rod 2 and is fastened by bolts 9. The center plate 1 is a circular plate structure. The telescopic rods 2 are arranged in a circular array around the outer periphery of the center plate 1, and the force is more uniform. When the center plate 1 and the telescopic rod 2 are fixed, the outer periphery of the center plate 1 is embedded in the slot of the telescopic rod 2 and fastened by bolts 9. The fixed position can be positioned by the slot, which is more convenient for installation. However, the following problems still exist in this patent:
