Technical Field

Background

More and more ships carry helicopters to perform different tasks. The hangar is a main place for parking and maintaining the helicopter, is a necessary guarantee for the helicopter to execute tasks of open sea and long-time residence, and is an essential facility for carrying the helicopter according to the requirement of the mission of a ship on one class of guarantee.

If the ship carrying the helicopter does not have a hangar, the helicopter cannot be used for staying training or long-term staying. Because the helicopter is the weakest equipment of the whole ship, the marine environment is severe, and the stern always waves, users all require that a hangar is arranged on the ship to protect the helicopter, and the ship only provided with the lifting platform cannot meet the requirement that the helicopter carries out long-distance tasks along with the ship.

For some small and medium-sized ships, the tonnage is small, the main dimension is small, but users often require to carry large and medium-sized helicopters and need to set hangars, the helicopters generally have large sizes, the total resources of the ships are limited, and fixed hangars cannot be set. Due to the limitation of the overall space, layout or other factors of the ship, when the fixed hangars cannot be arranged on the ship, the non-fixed hangars, namely the telescopic hangars, can be considered to be arranged to relieve the resource pressure of the ship overall.

The most common of the telescopic hangars is the telescopic hangar. The telescopic hangar is composed of a movable section and a fixed section, the fixed section is arranged at the front part of the hangar, the movable section pulled out from the fixed section is generally one to three sections, and the selection of the length of the movable section is determined according to the overall layout of the ship and the total length of the folded helicopter carried by the ship. When the helicopter takes off, the movable section retracts to make the deck space for taking off the helicopter; after the helicopter is landed, the movable section extends out, and a place for shielding wind and rain is provided for the helicopter.

In foreign countries, a small number of ships use hydraulic telescopic hangars, and compared with electric transmission mechanisms, the mechanisms are complex, hydraulic pipelines need to be laid, and the cabin capacity is occupied. A manual telescopic hangar moves a movable section of the telescopic hangar and opens and closes a hangar gate by a manual winch, and at least 5 persons need to operate together. Compared with an electric transmission mechanism, the manual winch has the advantages that the automation degree is not high, the force applied to the movable section during dragging is not uniform, the friction force between the bottom pulley and the guide rail is increased, the abrasion loss of equipment is large, and the service cycle is shortened.
