Description
Technical field
The present invention relates to passenger plane hatch door field of mechanisms, and in particular to a kind of passenger plane hatch door hoisting mechanism is mounted on half blocking
Formula hatch door, for controlling hatch door lifting motion.
Background technique
Passenger plane hatch door is mostly inwardly to be promoted upwards at present, flips outward half open blocking type hatch door.To realize that hatch door mentions
Elevator is dynamic, it usually needs the hoisting mechanism of a set of complexity of design is usually made of cam mechanism and four-bar mechanism.Cam mechanism control
Hatch door processed is promoted and other mechanism kinematics, and four-bar mechanism connects cam mechanism and opening mechanism, and its structure is complicated, number of parts
More, important big, volume is big, and practical application has certain limitation.
Summary of the invention
In view of the shortcomings of the prior art, providing a kind of passenger plane hatch door hoisting mechanism, which is the present invention
A kind of hoisting mechanism of integrated door bolt uses door bolt as power, coupler link formula is promoted and promotes locking mechanism, and mechanism is simple, part
Quantity is few, light-weight, applied widely, is suitble to be arranged on the narrow hatch door in inner space.
The technical solution adopted by the present invention are as follows: a kind of passenger plane hatch door hoisting mechanism is equipped with hatch door, in hatch door on fuselage frame
It is equipped with handle, handle is connect with the opening mechanism on hatch door, hingedly fastens axis with a bolt or latch on hatch door, and door bolt axis is connected by connecting rod and handle
It connects；In the both ends attachment lug of door bolt axis, idler wheel door bolt is connected on auricle, and door bolt corresponding with idler wheel door bolt position is equipped on fuselage frame
Slot, idler wheel door bolt are slidably connected with door bolt slot；It is fixedly connected with crank at the center of door bolt axis, crank connects latch hook, latch hook top by connecting rod
The sliding bar being arranged in the hook part and opening mechanism in portion overlaps；Pressure spring, pressure spring one end and door bolt axis are equipped in the outboard end of latch hook
Hingedly, the other end and hatch door are hinged；Sliding rail is symmetrical arranged on hatch door, sliding rail is equipped with slideway, and sliding bar is matched with slideway sliding
It closes.
The flute profile of the door bolt slot is the strip groove of external opening.
The two sides of the hatch door, which are symmetrical arranged, promotes guide roller, is equipped with guide groove in the corresponding position of fuselage frame, leads
It is inverted L-shaped groove to the groove shape of slot.
The hatch door is equipped with hatch door block, and fuselage block, the position of fuselage block and hatch door are equipped on fuselage frame
The position of block is corresponding.
The control method of passenger plane hatch door hoisting mechanism, feature the following steps are included:
1) opened door: pulling handle to make to fasten axis rotation with a bolt or latch, and door bolt axis is rotated upwards centered on the idler wheel of end door bolt, realizes hatch door
It is promoted, while promoting guide roller and being raised above along guide groove, sliding rail is raised above along sliding bar；
2) when door bolt axis continues rotation, idler wheel door bolt is displaced outwardly along door bolt slot, realizes outwardly opening for hatch door, after fully opening,
Idler wheel door bolt is detached from door bolt slot, promotes guide roller and is detached from guide groove, sliding rail slides to the other end along sliding bar；
3) for hatch door in lifting process, hatch door block avoids fuselage block；
4) pressure spring further pulls on door bolt axis, is hooked in latch hook on sliding bar, realizes that hatch door promotes locking；
5) hatch door, which falls, closes: moving handle, latch hook is detached from sliding bar unlock, and idler wheel door bolt, which resists door bolt slot upper surface, makes hatch door along leading
It moves downward to slot and sliding bar until hatch door reaches closed position.
The passenger plane hatch door hoisting mechanism uses four-bar mechanism, is driven by door bolt axis, and it is anti-that pressure spring makes latch hook tightly hook slide bar
Locking hook to improve the reliability of mechanism, while being defined hatch door position using door bolt slot and sliding rail, guarantees that hatch door opens road
Diameter.
The flute profile for fastening slot with a bolt or latch is the strip groove of external opening, is limited to the stroke in the middle part of hatch door.Guide groove is using inversion
L-type slot, the middle lower section of hatch door is limited.
Hatch door is equipped with hatch door block, and fuselage block is equipped on fuselage frame, guarantees that two blocks connect when hatch door is closed
Touching carries out position restriction.
The control method of passenger plane hatch door hoisting mechanism uses above-mentioned steps, locks hatch door at the end of improving promotion and is being promoted
The reliability of position.

Specific embodiment
As shown in Figures 1 to 4, a kind of passenger plane hatch door hoisting mechanism is equipped with hatch door 3 on fuselage frame 6, sets on hatch door 3
There is handle 12, handle 12 is connect with the opening mechanism 9 on hatch door, hingedly fastens axis 2 with a bolt or latch on hatch door 3, and door bolt axis 2 passes through connecting rod and handle
12 connections；In the both ends attachment lug of door bolt axis 2, idler wheel door bolt 4 is connected on auricle, is equipped on fuselage frame 6 and fastens 4 positions with a bolt or latch with idler wheel
Corresponding door bolt slot 5, idler wheel door bolt 4 are slidably connected with door bolt slot 5；It is fixedly connected with crank 14 at the center of door bolt axis 2, crank 14 passes through connecting rod
15 connection latch hooks 16, the hook part and the interior sliding bar 10 being arranged of opening mechanism 9 at 16 top of latch hook overlap；In the outside of latch hook 16
End is equipped with pressure spring 19, and 19 one end of pressure spring and door bolt axis 2 are hinged, and the other end and hatch door 3 are hinged；Sliding rail 8 is symmetrical arranged on hatch door 3,
Sliding rail 8 is equipped with slideway, and sliding bar 10 is slidably matched with slideway.Pressure spring 19 is constantly in compression in the entire motion process of hatch door 3
State, in closed position, original state pressure spring 19 drives door bolt axis 2 to be maintained at upper latch mode, when door bolt axis 2 turns to and pressure spring 19
When both ends interface point is conllinear, pressure spring 19 was in center critical localisation, continued to rotate door bolt axis 2, and pressure spring 19 drives door bolt after crossing center
The solution of axis 2 door bolt and auxiliary hatch door are promoted, and reduce hatch door lifting handle power；It is opposite with door opening process when door closing procedure.
The flute profile of the door bolt slot 5 is the strip groove of external opening；The two sides of the hatch door 3, which are symmetrical arranged, promotes guiding
Idler wheel 7 is equipped with guide groove 11 in the corresponding position of fuselage frame 6, and the groove shape of guide groove 11 is inverted L-shaped groove.
