Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, and in particular to a ship digging insulator tool and a use method thereof. Background Art

[0002] During the construction and use of ships, many rooms need to be fireproof and moisture-proof, and insulation laying work is carried out accordingly. Insulating rubber and other materials are used to cover the places where wire pipes pass through. In ship design, some rooms will inevitably have a large number of pipes, such as a liquid cargo transportation pipeline on a chemical ship with patent publication number CN110816757B. The invention discloses a liquid cargo transportation pipeline on a chemical ship, which includes a pipeline and at least one pair of long strip electrodes arranged on the inner wall or outer wall of the pipeline and wrapped in an insulating film, and a casing is set on the outside of the liquid cargo transportation pipeline.

[0003] These pipes will create gaps and holes when passing through various rooms. Considering the tightness of the ship, they must be blocked, but they must not affect the passage of the line pipeline. Therefore, during the construction of the ship, it is necessary to reserve pipe openings on the walls of these rooms, and when laying insulators in these rooms, insulators will be laid together with these pipe openings to block the reserved pipe openings. When the project progresses to laying pipes, it is necessary to open holes in the insulators at the reserved pipe openings, and correspondingly open holes of appropriate sizes. The traditional excavation method is to use a utility knife to make rectangular excavations on the insulation, or approximately circular excavations. This method not only wastes manpower and material resources and loses a lot of time, but also makes the excavated insulation ports not neat and beautiful, and the excavation port cannot be close to the pipe wall. Based on this, in actual operational practice, a device that can quickly excavate insulators is needed to meet this technical requirement. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a ship insulator digging tool and an insulation hole digging method to solve the problem that the existing digging of insulators requires manual digging, which not only wastes manpower and material resources, but also the excavated insulation ports are not neat and beautiful, and cannot fit the pipeline wall.
