Description

Technical Field

[0001] The utility model relates to the technical field of offshore oil drilling, in particular to an auxiliary supporter for a drill pipe of offshore oil drilling. Background Art

[0002] In the process of offshore oil extraction, drill pipe is an indispensable tool and can be reused. During the use of drill pipe, the mud, stone chips, oil stains generated by drilling, as well as seaweed, garbage and other debris in the seawater will adhere to the outer wall of the drill pipe, corroding the outer wall of the drill pipe, thus affecting the service life of the drill pipe. Therefore, the drill pipe must be cleaned after use. Since the diameter of the drill pipe used in petroleum machinery is large, the drill pipe needs to be clamped and fixed with an auxiliary support when cleaning the drill pipe to facilitate cleaning of its outer wall.

[0003] A Chinese patent with publication number CN218079525U discloses an auxiliary support for offshore oil drilling drill pipes, comprising: a support platform; a positioning device, wherein the positioning device is installed on the surface of the support platform and is used to lock the drill pipe on the surface of the support platform; by setting the positioning device, the staff can adjust the positions of the two positioning mechanisms through the adjustment mechanism, so that the two positioning mechanisms can adapt to drill pipes of different lengths, and at the same time, the staff can adjust the distance between the upper clamping frame and the lower clamping plate according to the diameter of the drill pipe, so that the positioning mechanism can adapt to drill pipes of different diameters, which enables the positioning device to lock drill pipes of different specifications, without the need to customize the corresponding auxiliary support for the drill pipe according to the specifications of the drill pipe, which expands the scope of application of the auxiliary support for the drill pipe and significantly improves the practicality of the auxiliary support for the pipe.

[0004] In the above technical solution, after the drill rod is fixed by the positioning device, it cannot rotate. During the cleaning process, the bottom and sides are difficult to clean. The distance between the upper clamping frame and the lower clamping frame needs to be manually adjusted to rotate the drill rod to ensure that the other surfaces of the drill rod can be cleaned, which is rather cumbersome.

[0005] Based on this, the utility model proposes an auxiliary supporter for a drill pipe of offshore oil drilling. Utility Model Content
