Description

Technical Field

[0001] The invention relates to the technical field of metal pipeline repair, in particular to a metal pipeline repair device for marine engineering. Background Art

[0002] The main methods of marine metal pipeline maintenance and repair can be divided into two categories: above-water repair and underwater repair. The above-water dry welding repair method for marine pipelines is usually to first cut off or remove the damaged section of the underwater pipeline, which is usually 1.5-2.5 meters, and then lift the pipeline out of the water and weld and repair the damaged section. For above-water repair, the removed pipeline section will be placed on the auxiliary pipe ship for welding repair, grinding, inspection, re-coating, and flange welding at the end of the pipeline. After NDT inspection and coating, the pipeline is installed back to the seabed, and the maintenance work is completed. The common method of underwater pipeline repair is to cut off the damaged pipe section, install a welding work cabin underwater, and inject high-pressure gas with the same pressure as the water depth in the sea area into the work cabin. After forming a dry environment, the pipe end of the sea pipe can be repaired, the short section can be installed, and underwater dry welding and other operations can be carried out.

[0003] According to a disclosed metal pipe repair device for marine engineering (authorization announcement number: CN 113102922 A), "the present invention discloses a metal pipe repair device for marine engineering, which relates to the technical field of metal pipe repair, including a rotating mechanism, on which a fixing mechanism is provided, and the rotating mechanism and the fixing mechanism are each provided with two groups, and the two groups of the rotating mechanism and the fixing mechanism are symmetrically arranged, and a welding mechanism is provided on one side of the rotating mechanism and the fixing mechanism. The device automatically fixes and rotates the metal pipe through the rotating mechanism, the fixing mechanism and the welding mechanism, utilizing the operation between its internal structures, thereby avoiding the inconvenience caused by manual rotation and improving the welding effect."

[0004] Although the device realizes automatic rotation and repair of metal pipes through various components, in the actual working process, since the device does not have a grinding mechanism to clean and grind the welding points, it is easy to affect the quality and strength in the subsequent welding repair process, and cause adverse effects such as poor air tightness. At present, the grinding of metal pipes is generally done manually, and there is a risk of injury during the grinding process. Therefore, we need to set up a metal pipe repair device for marine engineering to solve this problem. Summary of the invention
