Background

Helicopters are currently widely used on various marine vessels or platforms due to their unique safety, practicality and high efficiency. The operation modes of the helicopter are two types of landing operation and hovering operation, and a landing type is generally adopted for large-scale marine projects, so that a helicopter deck is equipped. The helicopter deck is made of steel and aluminum, and the aluminum helicopter deck is generally selected for reducing the weight of an empty ship and prolonging the service life of the helicopter deck. Aluminum helicopter decks are typically equipped with aluminum trusses, skid resistant surfaces, flumes, tie down points, safety nets, skid resistant nets, signs, landing aid systems, and fire protection systems.

The helicopter deck aluminum structure and the auxiliary system are assembled on a shipyard plane site, then the steel hoisting codes are installed, and finally the rigging is used for integral hoisting. Because the steel crane yard and the fixed of aluminium deck can only adopt the bolt fastening, therefore when the hoist and mount of helicopter deck are accomplished, the crane yard demolishs the back, can leave many bolt holes on the aluminium antiskid face of helicopter deck, and the oil that the helicopter leaked at ordinary times and the rainwater in rainy day can fall to the lower deck through these holes, probably arouse the incident, and relevant regulation mandates the requirement simultaneously, and the evacuation of helicopter deck must directly be discharged extraship, can not discharge outside through the whole drainage on the ship.

Therefore, it is necessary to design a plugging device for the bolt hole of the aluminum helicopter deck crane to solve the problems.
