Abstract

The invention provides a gangway ladder door retracting and releasing device. The gangway ladder door retracting and releasing device comprises a connecting mechanism (10) and a driving mechanism (40), wherein the connecting mechanism (10) is connected between a gangway ladder door (20) and a door frame (30) in a stretchable manner and can control opening or closing of the gangway ladder door (20); and the driving mechanism (40) is arranged on the door frame (30) or the gangway ladder door (20) and can drive the connecting mechanism (10) to execute retracting and releasing motions. According to the gangway ladder door retracting and releasing device provided by the invention, the structure is simple, the operation is flexible, the gangway ladder door retracting and releasing device is safe and reliable, the occupation space is small in after the gangway ladder door is retracted, and meanwhile, the gangway ladder door retracting and releasing device can also be used as a handrail.

Description

technical field [0001] The invention relates to the field of aircraft gangway door auxiliary mechanical devices, in particular to a gangway door retractable device. Background technique [0002] The gangway door retractable device is installed between the gangway door and the body, and is mainly used for stowing and lowering the gangway door. It also has the function of a handrail, which can play a role of protection and support when passengers pass by the gangway door. [0003] The existing gangway door retractable device has a complex structure, and when the gangway door is in a closed state, it takes up a large space, is very inconvenient to operate, and is not conducive to the layout of the overall structure. Contents of the invention [0004] The invention provides a retractable device for gangway doors, which is simple in structure, flexible in operation, safe and reliable, takes up little space when retracted, and can be used as a handrail at the same time. [0005...
