Method for batch-coating epoxy resin on corner insulation box of LNG (Liquefied Natural Gas) ship liquid cargo tank

Abstract

The invention discloses a method for batch-coating an epoxy resin on a corner insulation box of an LNG (Liquefied Natural Gas) ship liquid cargo tank, and belongs to the technical field of ship construction. The method comprises the steps of (1) adjusting a position of a sliding cross beam of an auxiliary device according to a size of the corner insulation box to be coated; (2) placing the cornerinsulation box to be coated on the auxiliary device; (3) adjusting a position of the corner insulation box to be coated on the auxiliary device, and locking and positioning the corner insulation box to be coated; and (4) placing the auxiliary device and the corner insulation box to be coated on an epoxy resin coating machine, comparing information, and coating. The method provided by the inventionis simple and convenient in operation steps and easy to grasp; by utilizing the steps of the method, multiple corner insulation boxes to be coated can be coated at the same time, so that the coatingefficiency is higher; the multiple corner insulation boxes to be coated are placed on the auxiliary device in parallel, so that the coating accuracy is higher; and operating personnel can carry the multiple corner insulation boxes at the same time, so that the labor intensity is reduced, and the labor efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a batch-coating method of epoxy resin for corner insulating boxes of liquid cargo tanks of LNG ships. Background technique [0002] LNG ships, especially No.96 membrane-type LNG ships, have high requirements on the flatness of liquid cargo tanks. The liquid cargo containment system is mainly composed of main and secondary insulation boxes and main and secondary invar steel, which can isolate liquefied natural gas. Prevent it from absorbing heat from the cargo tank, while transferring the pressure of the LNG to the cargo tank, and ensuring that the LNG does not leak. The transmission of liquid natural gas pressure is mainly realized through the epoxy resin strips coated according to the designed track and type on the secondary insulation box. [0003] With a cabin capacity of 174,000 m 3 Take the No.96 film-type LNG ship in China as an example, there are more th...
