Description

Technical Field

[0001] The utility model relates to the technical field of ship construction equipment, in particular to a construction operation platform. 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 construction of the cargo tank is the most difficult part of the construction of LNG ships. Two layers of thermal insulation need to be laid inside the cargo tank of the LNG ship to ensure that the temperature inside the cargo tank reaches minus 163 degrees Celsius. After the insulation board is laid, a layer of Invar steel needs to be covered on its surface. The Invar steel layer is composed of several Invar steel units. Invar steel can prevent the leakage of natural gas liquid inside. The insulation board is generally assembled from multiple insulation boxes. During the installation of the insulation board, a giant operating table needs to be built with the help of special scaffolding;

[0003] In the actual construction process, since the bottom of the two side walls of the liquid cargo tank has a 45-degree inclined surface, after the insulation board on the inclined surface is laid, when welding the Invar steel on the surface of the insulation board, since the Invar steel layer also has a 45-degree inclined surface and the Invar steel cannot be stepped on or squeezed, a giant operating table built with a special scaffolding is required. However, this giant operating table is difficult to adjust and has poor maneuverability, which is not conducive to welders adjusting the welding position, greatly limiting the workers' efficiency in welding the Invar steel layer.
