Abstract
The present invention relates to a kind of novel cabin door actuator, the damping that power and the buffer movement that the present apparatus is generated using torsion bar torsional deflection generate, which opens the door to move for gangway ladder door, provides resistance.The present apparatus is replied the power gangway ladder door movement generated using torsion bar torsional deflection and provides power-assisted.It is worked in the present apparatus by main torsion bar and balance torsion rod in different time or path to adjust resistance or power-assisted in the size in different time or path.
Description
Technical field
The present invention relates to gangway ladder door actuation technologies.
Background technique
Existing gangway ladder door acting device has hydraulic actuation device, electrical actuation acting device and hawser.Hydraulic actuation device is logical
It crosses aircraft hydraulic source and hydraulic energy driving acting device either on or off gangway ladder door is provided, electrical actuation device is mentioned by aircraft power
For electrical energy drive acting device either on or off gangway ladder door, hawser is that personnel pull hawser to open and close gangway ladder door.Hydraulic actuation
Device, electrical actuation acting device need the aircraft energy and a set of control system, expend effective energy, product is complicated, reliability
It is low, it is less economical.Hawser requires height to operator, and strength is needed to meet switch gangway ladder door requirement, and personnel safety is low.
Summary of the invention
Technical solution
The present invention provides a kind of novel cabin door actuator, the actuator include buffer 2, cable disk component 3, wirerope 4,
Transmission shaft 5, gear pair 6, main torsion bar 7 and balance torsion rod 8；
Buffer 2 is unidirectional pressurized strut；
Cable disk component 3 is fixed on transmission shaft, wirerope 4 is wound on cable disk component 3, and one end of wirerope 4 is cabin
1 union end of door, the other end of wirerope 4 are fixing end；
Transmission shaft one end is provided with convex block, and 8 one end of balance torsion rod is cannula structure, is provided in cannula structure inner wall convex
Block, cannula structure are socketed in described transmission shaft one end, and after transmission shaft rotates by a certain angle, transmission shaft convex block can be with casing knot
The convex block of structure engages, so that transmission shaft drives balance torsion rod 8 to reverse；
The transmission shaft other end is coupled by gear pair 6 with main torsion bar 7, is reversed when transmission shaft rotation will drive main torsion bar 7；
The transmission shaft other end also couples with buffer 2, and when transmission shaft drives the torsion of main torsion bar 7, buffer 2 is transmission shaft
Apply damping.
Cable disk component 3 is two groups.
In use, 1 opening procedure of hatch door or gangway ladder door, steel wire rope component stretches out driving cable disk component rotation, and torque is passed
It passs balance torsion rod and main torsion bar component is delivered torque to by transmission shaft component and gear assembly.Balance torsion rod and main torsion bar
Torsional deflection generates resistance, while the draught control for cooperating buffer to generate guarantees that gangway ladder door is beaten according to regular hour speed
It opens.Balance torsion rod and main torsion bar torsional deflection store energy in the process.Balance torsion rod and main torsion when gangway ladder door is closed
Rod twisting deformation-recovery, releases energy, and closes the door for operator and provides power-assisted, guarantees gangway ladder door under certain operating force effect
It completes to close.
Entire switch gangway ladder door process is not necessarily to power supply and hydraulic power source, by torsion bar technical application gangway ladder door actuator, main torsion bar
For undertaking main resistance/power-assisted, balance torsion rod makes up resistance/power-assisted needed for local paragraph, realizes novel gangway ladder door actuation
Device assist operators are manually opened and close gangway ladder door.It is easy to operate, high reliablity.Hatch door or gangway ladder door opening procedure are turned round
Bar provides the opening speed of main resistance secondary buffer control door.Two groups of steel wire rope components are connect with door two sides, are conducive to door
The rigidity of structure.
Technical effect
Using with aircraft gangway ladder door, the energy is saved without hydraulic power source and power supply, and reliance security is high, it is economical
Property is good.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is principle of the invention figure；
Wherein: hatch door 1, buffer 2, cable disk component 3, wirerope 4, transmission shaft 5, gear pair 6, main torsion bar 7, balance torsion rod
8。
Specific embodiment
Referring to attached drawing, a kind of novel cabin door actuator is provided, which includes buffer 2, cable disk component 3, steel wire
Rope 4, transmission shaft 5, gear pair 6, main torsion bar 7 and balance torsion rod 8；
Buffer 2 is unidirectional pressurized strut；
Cable disk component 3 is fixed on transmission shaft, wirerope 4 is wound on cable disk component 3, and one end of wirerope 4 is cabin
1 union end of door, the other end of wirerope 4 are fixing end；
Transmission shaft one end is provided with convex block, and 8 one end of balance torsion rod is cannula structure, is provided in cannula structure inner wall convex
Block, cannula structure are socketed in described transmission shaft one end, and after transmission shaft rotates by a certain angle, transmission shaft convex block can be with casing knot
The convex block of structure engages, so that transmission shaft drives balance torsion rod 8 to reverse；
The transmission shaft other end is coupled by gear pair 6 with main torsion bar 7, is reversed when transmission shaft rotation will drive main torsion bar 7；
The transmission shaft other end also couples with buffer 2, and when transmission shaft drives the torsion of main torsion bar 7, buffer 2 is transmission shaft
Apply damping.
Cable disk component 3 is two groups.
