Abstract
The present invention relates to a kind of novel cabin door actuator, the damping that power and the buffer motion that the present apparatus is produced using torsion bar torsional deflection are produced provides resistance for gangway ladder door enabling motion.The present apparatus is replied the power gangway ladder door motion produced using torsion bar torsional deflection and provides power-assisted.The size of resistance or power-assisted in different time or path is adjusted in different time or path work by main torsion bar and balance torsion rod in the present apparatus.
Description
Technical field
The present invention relates to gangway ladder door start technology.
Background technology
Existing gangway ladder door acting device has hydraulic actuation device, electrical actuation acting device and hawser.Hydraulic actuation device leads to
Cross aircraft hydraulic source and hydraulic energy driving acting device either on or off gangway ladder door is provided, electrical actuation device is carried 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, and product is complicated, reliability
It is low, it is less economical.Operating personnel are required with high for hawser, it is necessary to which strength meets switch gangway ladder door requirement, and personnel safety is low.
The content of the invention
Technical scheme
The invention provides a kind of novel cabin door actuator, the actuator include buffer 2, cable disk component 3, steel wire rope 4,
Power 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 with power transmission shaft, steel wire rope 4 is wound on cable disk component 3, and one end of steel wire rope 4 is cabin
1 union end of door, the other end of steel wire rope 4 is fixing end；
Power transmission shaft one end is provided with projection, and the one end of balance torsion rod 8 is sleeve structure, is provided with sleeve structure inwall convex
Block, sleeve structure is socketed in described power transmission shaft one end, and after power transmission shaft rotates to an angle, power transmission shaft projection can be with sleeve pipe knot
The projection locking of structure so that power transmission shaft drives balance torsion rod 8 to reverse；
The power transmission shaft other end is coupled by gear pair 6 with main torsion bar 7, when drive axis can drive main torsion bar 7 to reverse；
The power transmission shaft other end also couples with buffer 2, and when power transmission shaft drives main torsion bar 7 to reverse, buffer 2 is power transmission shaft
Apply damping.
Cable disk component 3 is two groups.
In use, hatch door or the opening procedure of gangway ladder door 1, steel wire rope component are stretched out driving cable disk component and rotated, moment of torsion is passed
Pass 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 produces resistance, while the draught control for coordinating buffer to produce ensures that gangway ladder door is beaten according to regular hour speed
Open.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 is that operating personnel close the door offer power-assisted, it is ensured that gangway ladder door is under certain operating physical force effect
Complete to close.2. new gangway ladder door actuator according to claim 1, it is characterised in that：Whole switch gangway ladder door process
Without power supply and hydraulic power source, by torsion bar technology application gangway ladder door actuator, main torsion bar is used for undertaking main resistance/power-assisted, balances
Torsion bar makes up resistance/power-assisted needed for local paragraph, realizes that new gangway ladder door actuator assist operators are manually opened and close
Close gangway ladder door.Easy to operate, reliability is high.Hatch door or gangway ladder door opening procedure, torsion bar provide main resistance secondary buffer control
The opening speed of door processed.Two groups of steel wire rope components are connected with door both sides, are conducive to the rigidity of structure of door.
Technique effect
It is economical using with aircraft gangway ladder door, the energy, and reliance security height are saved without hydraulic power source and power supply
Property is good.
