Description

Technical Field

[0001] The utility model relates to the technical field of ship repair, in particular to a protective device for equipment entering and exiting a cabin. Background Art

[0002] LNG ships transport flammable and explosive liquefied natural gas, so cabin protection is crucial. Good cabin protection can effectively prevent damage to the cabin structure and avoid natural gas leaks. Once a leak occurs, it may cause serious accidents such as fire and explosion, threatening the lives of the ship and crew, and also causing great damage to the marine environment. Therefore, timely maintenance and repair of cabin equipment is necessary. During maintenance and repair, when equipment enters and exits the cabin, due to factors such as the equipment's own weight, shape, and possible unstable movement, it is easy to cause collisions, scratches, and other damage to the structure and facilities inside the cabin, as well as equipment and personnel outside the cabin, including the equipment entering and exiting the cabin. The current protective measure is to open the protective cover and directly lift it with a crane. During lifting, the lifting parts swing around, which is not perfect and cannot effectively prevent damage to the equipment itself, as well as to the equipment and personnel inside and outside the cabin.
