Description
Technical field
The invention belongs to civil aircraft cabin door mechanism technology, relate to a kind of lift system of outward opening cabin door.
Background technology
The in-flight locking reliability of civil aircraft cabin door, safety are hatch door design-calculated keys, and hatch door awing accident is opened, and cause the unexpected release in main cabin, tend to cause fatal crass's accident.Hatch door can be divided into swing-in hatch door and outward opening cabin door according to opening direction.The swing-in hatch door is " blocking type " hatch door, and power transmission is simple, reliable, realizes the security requirement of hatch door locking easily, but because the swing-in hatch door takies space in the cabin in the opening and closing process, so the civil aircraft cabin door adopts outward opening cabin door mostly.In order to make outward opening cabin door realize the force-transfer characteristic of blocking type hatch door, the civil aircraft outward opening cabin door adopts " lifting-external-open mode " more at present.The lift system that Boeing series passenger plane promotes outward opening cabin door is a cam mechanism, drives the lifting rocking arm by the face cam that is connected on the arm pivot post, and hatch door is promoted.Cam mechanism is had relatively high expectations to accuracy of manufacture, and manufacturing and installation are comparatively difficult, cost is high.
Summary of the invention
The lift system that the purpose of this invention is to provide a kind of outward opening cabin door easy to manufacture and install.
Technical scheme of the present invention is: lift system is made up of a lifting rocking arm, lifting arm, last lift arm, a following lift arm.Mechanism's mount pad and hatch door are connected, and the end and the arm pivot post that promote rocking arm are connected, and arm pivot post is installed on mechanism's mount pad, and the other end and the lifting arm upper end that promote rocking arm are hinged.The rod end joint of the lower end of lifting arm and the middle part of last lift arm are hinged, and an end of last lift arm is installed on mechanism's mount pad, and the other end and the backing block on the axis of guide of last lift arm are hinged; The outer end of main hinge is provided with ears and following ears, the axis of guide places in the through hole of the upper and lower ears in outer end of main hinge, be provided with backing block on the axis of guide between two of two of last ears of main hinge and the following ears, main hinge and hatch door doorframe are hinged, following lift arm and an end be installed on mechanism's mount pad, the other end and the axis of guide are hinged.When the stick control arm pivot post rotated counterclockwise, it was fulcrum with the main hinge that arm pivot post drives lift system, and hatch door is promoted or depresses.When opening hatch door, hatch door is raised, and hatch stop breaks away from doorframe block, extrapolated again opening; When closing hatch door, inwardly spur hatch door, make hatch stop be positioned at doorframe block inboard, depress hatch door again, make the engagement of hatch stop and doorframe block, make hatch door become the blocking type hatch door, have safe and reliable locking.
Rod end joint on the described lifting arm is provided with the adjustment swivel nut of regulating lifting arm length, with the manufacturing of compensation part, mechanism error of mean squares is installed.
The middle part of the described axis of guide is provided with power assistant spring, and hatch door is opened the power-assisted effect of playing.
Advantage and beneficial effect that the present invention has are, lift system principle of the present invention is two continuous four-bar linkages, mechanism is simple, dependable performance, part is easy to make, provide the indemnifying measure of adjusting has been installed, reduced manufacturing, the cost of installation of hatch door mechanism, be applicable to that civil aircraft cabin door mechanism uses.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a main hinge structural representation of the present invention.
The specific embodiment
Below the present invention is described in further details, referring to Fig. 1, Fig. 2.
Lift system of the present invention by one promote rocking arm 2, lifting arm 3, go up lift arm 4, lift arm 5 is formed down.Mechanism's mount pad 8 is connected with hatch door 7, the end and the arm pivot post 1 that promote rocking arm 2 are connected, on the arm pivot post 1 mount pad mechanism mount pad 8, the other end and lifting arm 3 upper ends that promote rocking arm 2 are hinged, the rod end joint 11 of the lower end of lifting arm 3 is hinged with the middle part of last lift arm 4, and the left end of last lift arm 4 is installed on mechanism's mount pad 8.The four-bar linkage of promote rocking arm 2, lifting arm 3, go up lift arm 4, mechanism's erection support 8 being formed a double rocking lever when the stick control arm pivot post rotates, will drive the lift arm motion.Backing block 12 on the other end of last lift arm 4 and the axis of guide 9 is hinged; One end of following lift arm 5 is installed on mechanism's mount pad 8, backing block 12 on the other end and the axis of guide 9 is hinged, the outer end of main hinge 6 is provided with ears 13 and following ears 14, the axis of guide 9 places in the through hole of the upper and lower ears in outer end of main hinge 6, be provided with backing block 12 on the axis of guide 9 between 14 two of 13 two of last ears of main hinge 6 and the following ears, main hinge 6 is hinged with the hatch door doorframe.Last lift arm 4, following lift arm 5, mechanism's erection support 8, the axis of guide 9 are formed a parallel four-bar linkage, when last lift arm 4 is raised bar 3 drives, the axis of guide 9 is moved downward to the auricle of main hinge 6 with two backing blocks 12 and contacts, and is fulcrum with main hinge 6 again, promotes hatch door 7 and promotes.
The middle part of the described axis of guide 9 is provided with power assistant spring 15, plays the power-assisted effect in the process of opened door, after hatch door is closed, hatch door to pressing down, is prevented that hatch door from upspringing, and plays the safety effect.
Using method of the present invention and working process are: when opening the door, on the handle of raising one's hand, drive lift system by arm pivot post 1, lift system is a fulcrum with main hinge 6, lead agency erection support 8 and hatch door 7 promote, and the retainer of hatch door and doorframe load block break away from, the extrapolated again hatch door of opening; At closing time, inwardly spur hatch door, make hatch stop be positioned at doorframe block inboard, press down handle, drive lift system by arm pivot post 1, lift system is a fulcrum with main hinge 6, drive hatch door 7 and descend, the retainer of hatch door 7 and the engagement of doorframe load block, hatch door 7 is closed.
