Abstract
The invention belongs to the technical field of airplane hydraulic system hatch door control, and relates to a multi-angle control technology for a hatch door in an airplane hydraulic system. The characteristic that when the hatch door is on different open positions, the operating stroke of an actuator cylinder piston rod is different is fully utilized, the actuator cylinder of the airplane hatch door is specially designed, the multi-angle control demand of the hatch door is satisfied, and the operation is simple.
Description
Technical field
The invention belongs to plane hydraulic system hatch door control technology field, is related to a kind of aircraft polygonal
Degree control hatch door.
Background technology
Hatch door steerable system belongs to the hydraulic system in aircraft mechanical system, is driven using hydraulic oil
Pressurized strut enforcement action, with hydraulicdirectional control valve the switch of hatch door is completed.Hatch door control both at home and abroad at present
Technology processed is simpler, can only reach hatch door in ground open and close.If necessary to aerial unlatching
To certain angle, individually designed a set of complicated aerial drag link mechanism is needed, make structure become multiple
It is miscellaneous.
The content of the invention
Present invention solves the technical problem that being：There is provided a kind of simple structure, can multi-angle control
Hatch door.
The technical scheme is that：Hatch door is connected with pressurized strut, it is characterized by：Described work
Dynamic cylinder include outer tube 804, microswitch 805, shift fork 806, steel ball 807, piston rod 808,
Rotating shaft 811 and briquetting 812, piston rod 808 is arranged on outer tube 804, sets on piston rod 808
Boss is equipped with, steel ball 807 is arranged in the wall of outer tube 804, and rotating shaft 811 is arranged on outer tube 804
Outward, briquetting 812 is fixed with shift fork 806, shift fork 806 is hinged with rotating shaft 811, not with
The top of steel ball 807.
Improve as one kind of the technical program, the boss on piston rod 808 pushes up steel ball 807
When rising, hatch door opening angle is 30 °.
Beneficial effects of the present invention are：By designing convex on hatch door pressurized strut internal piston bar
Platform, designs the mode of shifting fork mechanism on pressurized strut outer tube, pressurized strut is had in motor process
There are two kinds of impulse strokes, realize the multi-angle control of hatch door.
Description of the drawings
Fig. 1 is the schematic diagram of the present invention；
Fig. 2 is the structural representation of pressurized strut；
Fig. 3 is the longitudinal sectional view of pressurized strut；
In figure：Oil-feed ozzle 801, oil return ozzle 802, cylinder adapter assembly 803, outer tube 804,
Microswitch 805, shift fork 806, steel ball 807, piston rod 808, tail-hood 809, knock-off joint
Component 810, rotating shaft 811, briquetting 812.
Specific embodiment
The technical program is described in further details below in conjunction with the accompanying drawings.
As shown in figure 1, the hatch door described in the technical program is hinged with pressurized strut, the multi-angle control of hatch door
System is realized by the way that many sizes of pressurized strut are flexible.As shown in Figures 2 and 3, described pressurized strut includes
Oil-feed ozzle 801, oil return ozzle 802, cylinder adapter assembly 803, outer tube 804, microswitch
805th, shift fork 806, steel ball 807, piston rod 808, tail-hood 809, knock-off joint component 810,
Rotating shaft 811 and briquetting 812, piston rod 808 is arranged on outer tube 804, sets on piston rod 808
Boss is equipped with, steel ball 807 is arranged in the wall of outer tube 804, and rotating shaft 811 is arranged on outer tube 804
Outward, briquetting 812 is fixed with shift fork 806, shift fork 806 is hinged with rotating shaft 811, not with
The top of steel ball 807.Oil-feed ozzle 801 and oil return ozzle 802 are arranged on start barrel,
Pressurized strut is respectively fixed at two ends with an adapter assembly 803 and knock-off joint component 810, tail-hood 809
It is sealingly mounted on pressurized strut barrel.
In addition, in the air from safety considerations, the boss on piston rod 808 is by steel ball 807
During jack-up, hatch door opening angle is 30 °, is used as emergency escape passage, is met winged
Machine many-side demand.
When hydraulic oil Jing ozzles 801 enter hatch door start tube inner chamber, piston rod movement is promoted, when
(with the horizontal 30 ° of angular positions) during piston rod movement 234mm, on the left of piston rod
Boss rises steel ball 807, and steel ball pushes shift fork 806 makes shift fork 811 rotate around the shaft, band
Briquetting 812 in dynamic rotating shaft is rotated, and makes briquetting compress the contact of microswitch 805, microswitch
The signal of telecommunication is sent, system stops voltage supply, and now hatch door is opened to 30 °.If again from pipe
Mouth 801 is passed through pressure oil, and piston rod continues to move.When piston rod movement is to 275mm (with
Horizontal plane is into 40 ° of angular positions), piston rod is in fully extended state, and hatch door is opened maximum
To 40 °.
A kind of aircraft multi-angle hatch door control of the present invention, by hatch door pressurized strut internal piston bar
Upper design boss, designs the mode of shifting fork mechanism on pressurized strut outer tube, makes pressurized strut in motion
During there are two kinds of impulse strokes, and configure left and right two sets of hydraulic system voltage supply, complete
Hatch door in the air and on the ground, it is normal with emergent two kinds of different open angles.
