Description

Technical Field

[0001] The utility model relates to the technical field of ship construction, in particular to a top supporting device for laying insulation boards of liquid cargo tanks. Background Art

[0002] LNG ship refers to a "ship" that is specially used to transport liquefied natural gas. Liquefied gas is stored in the cargo tank of the LNG ship. The storage of liquefied gas requires that the internal temperature be maintained at -162°C to ensure that the LNG cargo is in a stable state. -162°C is an extremely low temperature, which usually only occurs in extremely cold areas or high altitude areas. At this temperature, most substances will become very fragile and easy to break or damage. Therefore, when transporting LNG cargo, it is necessary to lay a liquid cargo maintenance system around the cargo tank. The liquid cargo maintenance system is the isolation barrier and thermal insulation system of the cargo tank to prevent the cargo tank from contacting the low-temperature LNG cargo, making the tank brittle and causing shipping accidents; the insulation board is an important part of the liquid cargo maintenance system. At present, during the operation of laying insulation boards in the cargo tank, the insulation board on the top is the most difficult to lay. In addition, the top of the cargo tank has a slope structure. When laying the insulation board on the side, it needs to be buckled with the insulation board on the top edge. During this period, the insulation board laid on the top will be subjected to a large downward pull force, which requires ensuring that the insulation board installed on the top of the cargo tank is firm, reliable, and does not move or fall.

[0003] At present, the installation of the insulation board on the top of the liquid cargo tank is carried out by fixing the insulation board to the tank body through a simple connecting tool.
