Abstract

The invention discloses a hangar door body structure with an icing prevention function and a manufacturing process thereof, and relates to the field of ocean engineering equipment and high technology ships, in particular to a multifunctional integrated hangar door body structure design. The main structure of a door body is a lattice metal corrugated sandwich structure and is prepared by an inner side panel, an outer side panel and a corrugated core body through laser welding; and meanwhile, hot air flow holes and flow pipes are designed in the corrugated core body, a partially communicating core body flow space is formed, the outer side panel is heated by controlling hot air or hot steam to flow in the core body flow space, and an icing prevention purpose is achieved. The weight of the door body structure can be reduced by 10%-25% compared with the weight of an existing plate rib structure door body, and the multifunctional characteristics of bearing, explosion prevention, icing prevention and the like are combined at the same time. The disclosed hangar door body structure and the manufacturing process thereof are suitable for all kinds of hangar door bodies and some other large protective structures with anti-explosion and heat preservation requirements.

Description

technical field [0001] The invention belongs to the technical field of marine engineering equipment and high-tech ships, and in particular relates to the design and manufacturing process of an anti-icing door body with a lattice metal interlayer structure. Background technique [0002] At present, hangar doors can be divided into two types from the opening method: push-pull doors and hanging lift doors. For large-scale marine equipment, the hangar mainly adopts push-pull doors, and the door structure is mainly a rib structure. In the case of meeting the load-bearing requirements, the door body with plate reinforcement structure has the disadvantage of heavy weight, which makes it time-consuming and laborious to open and close the door body manually. In special circumstances, the rapid opening and closing of the door body is particularly important, otherwise it will bring serious consequences, even catastrophic accidents, so it is necessary to reduce the weight of the existi...
