A handheld cutting machine for hull maintenance

Abstract

This utility model discloses a handheld cutting machine for ship hull maintenance, including a support plate. A positioning component is fixedly mounted on the support plate for positioning the machine around the outside of a ship's pipe. A side plate is fixedly mounted on the left side of the support plate, a handle is fixedly mounted on the left side of the side plate, and a baffle is fixedly mounted on the bottom of the side plate. This utility model, by setting up a positioning component, a movable component, an electric push rod, and a cutting machine, allows the positioning component to be fastened to the outside of the ship's pipe to be cut. Rotating the positioning screw causes the second clamping plate to come close to the first clamping plate and clamp the ship's pipe. Rotating the adjusting screw moves the cutting machine to the appropriate position, and the electric push rod drives the cutting machine to cut. Thus, during the cutting process, the positioning component is clamped to the outside of the ship's pipe, and the user can stabilize the device by holding the handle, which is relatively labor-saving. During the cutting process, the electric push rod drives the cutting machine to cut, eliminating the need for manual operation of the cutting machine, making the entire cutting process more labor-saving.

Description

Technical Field

[0001] This utility model relates to the field of ship hull maintenance cutting machines, and in particular to a handheld cutting machine for ship hull maintenance. Background Technology

[0002] Pipelines on ships are mainly used for drainage, ventilation, or liquid transportation. Common types include drain pipes for quickly removing deck water, ballast water pipes for injecting and draining seawater to adjust the ship's stability, fuel oil pipes for loading and unloading oil, ventilation pipes for balancing cargo hold pressure or dissipating odors, and some pipes are also involved in fire protection systems or sewage discharge. These pipes are usually made of corrosion-resistant metals (such as galvanized steel or stainless steel), extend directly to the outside, and require regular maintenance to prevent rust or blockage.

[0003] Ships are exposed to seawater, humid air, chemicals, and other environments for extended periods, making metal pipes susceptible to electrochemical corrosion, pitting, or rust. This can lead to thinning of the pipe walls, leaks, or even ruptures. These pipes are mostly made of steel with an anti-corrosion coating. When the coating peels off, the exposed steel pipe often corrodes rapidly. The maintenance solution is to cut off the corroded pipe and replace it, and then apply anti-rust treatment to the joints. When maintaining these pipes on the ship's hull, manual cutting of the pipes is often the primary method. However, cutting steel pipes is extremely laborious. Therefore, a handheld cutting machine for ship hull maintenance is proposed. Utility Model Content
