Embodiment Construction

[0017] Referring to the accompanying drawings, a novel hatch actuator is provided, which includes a buffer 2, a cable drum assembly 3, a wire rope 4, a transmission shaft 5, a gear pair 6, a main torsion bar 7 and a balance torsion bar 8;

[0018] The buffer 2 is a one-way actuator;

[0019] A cable drum assembly 3 is fixed on the transmission shaft, and a steel wire rope 4 is wound on the cable drum assembly 3, and one end of the steel wire rope 4 is the connecting end of the cabin door 1, and the other end of the steel wire rope 4 is a fixed end;

[0020] One end of the transmission shaft is provided with a bump, and one end of the balance torsion bar 8 is a sleeve structure, and the inner wall of the sleeve structure is provided with a bump, and the sleeve structure is sleeved on one end of the transmission shaft. The shaft protrusion will be locked with the protrusion of the casing structure, so that the transmission shaft drives the balance torsion bar 8 to twist;

Abstract

The invention relates to a novel cabin door actuator. According to the device, force produced by torsional deformation of torsion rods and damping produced by motion of a buffer are utilized to provide resistance for door opening motion of an accommodation ladder door; force produced by torsional deformation recovery of the torsion rods is utilized to provide assist force for motion of the accommodation ladder door; and the main torsion rod or the balance torsion rod works in different time or different paths so as to adjust the magnitude of the resistance or the assist force in the different times or the different paths.

Description

technical field [0001] The invention relates to the actuating technology of gangway doors. Background technique [0002] Existing ramp door actuating devices include hydraulic actuating devices, electric actuating devices and cables. The hydraulic actuating device provides hydraulic energy through the aircraft hydraulic source to drive the actuating device to open and close the gangway door. The electric actuating device provides electric energy through the aircraft power supply to drive the actuating device to open and close the gangway door. The cable is pulled by the personnel to open and close the gangway door. Hydraulic actuating devices and electric actuating devices require aircraft energy and a set of control systems, consume effective energy, have complex products, low reliability, and poor economy. The cables have high requirements on the operators, requiring strength to meet the requirements of opening and closing the gangway door, and the safety of personnel is ...
