Description

Technical Field

[0001] The utility model relates to the technical field of cutting clamps, in particular to a ship maintenance pipeline cutting clamp. Background Art

[0002] Ship pipelines are pipes used to connect various mechanical equipment on ships and to transmit water, oil, gas and other related working fluids. In the process of repairing ship pipelines, they usually need to be cut. In order to prevent the cutting from deflecting and to stabilize the cutting of the pipeline, a cutting fixture is needed to fix the ship pipeline.

[0003] According to the description in the ship maintenance pipe cutting fixture disclosed on the patent website (authorization announcement number: CN 219310216 U), "the utility model belongs to the technical field of cutting equipment, and specifically relates to a ship maintenance pipe cutting fixture. The limiting support roller is arranged above the bottom plate, and a limiting support roller is arranged between the limiting support roller and the bottom plate. There are slide grooves on both sides of the upper part of the bottom plate, and the slider is arranged in the slide groove. The bottom of the support frame is fixed to the upper part of the slider. The slider and the slide groove are slidably matched, and there is a threaded shaft inside the slide groove. The distance between the limiting drive wheels on both sides can be adjusted, so that the limiting drive wheel and the limiting support roller are against the outer wall of the pipe, and the external cutting equipment starts to cut the round pipe. Since the position of the cutting machine is relatively fixed, the driving handle is turned after the pipe is partially cut, so that the driving handle drives the limiting drive wheel to rotate, and the rotation of the limiting drive wheel will cause the pipe to rotate, so that the cutting machine continues to cut; therefore, the utility model can stably clamp round pipes of different diameters and assist in cutting, and can adapt to various processing needs such as welding and painting in addition to cutting."

However, in actual use, when the clamped pipeline has a large diameter and a heavy weight, it takes a lot of effort and time to rotate the limiting driving wheel, resulting in low cutting efficiency.
