Background technique
Unmanned plane way of recycling has undercarriage running landing, parachute recycling, intercept net recycling, air bag recycling, air cushion to return
Receipts, aerial recycling, vertical landing etc..
Undercarriage running landing requires runway do not have man-machine height, some Landing Gear Designs are more fragile, damage suction with hitting
Energy is received, some band pintles can hook interception rope and slow down as early as possible.
Parachute recycling: large-scale unmanned plane is recycled in narrow and small place, and body contact site need to install damping device, is inflated
Bag, shock-damping structure etc., contact site is as far as possible far from equipment compartment.
Intercept net recycling is primarily directed to small drone, and overload of touching net is no more than 6g.
Air cushion recovery principle is similar with air cushion vehicle and aircushion vehicle, and air is pressed into air bag by engine, and compressed air is from bag hole
Middle ejection forms pressure-air area-air cushion in ventral, and landing is not limited by surface condition, do not limited, recycled by size, weight
Rate is high.
Aerial recycling, it is costly, it is desirable that high, risk is high, and only the U.S. uses at present.

On this arm 3-1) it is connected with the tail portion of I 3-2 of cross bar telescopic arm, II 20-2 of rope socket is connected with I head 3-1 of cross bar telescopic arm.
When brake motor 19 rotates clockwise, brake motor 19 is rotated clockwise with roller 21, hauls rope socket I
20-1 is moved to 19 direction of brake motor, and I 3-2 of cross bar telescopic arm is retracted.(cross bar is flexible for the synchronous retraction of II 3-2 of cross bar telescopic arm
The synchronization telescope principle of II 3-2 of arm compared with telescopic crane boom principle, this will not be detailed here).
When brake motor 19 rotates counterclockwise, brake motor 19 rotates counterclockwise with roller 21, hauls rope socket II
20-2 is moved away from 19 direction of brake motor, and I 3-2 of cross bar telescopic arm stretches out.II 3-2 of cross bar telescopic arm is synchronous to stretch out (cross
The synchronization telescope principle of bar telescopic arm II compared with telescopic crane boom principle, this will not be detailed here).
The bottom surface of pedestal 6 is equipped with a circle threaded connection hole I 17, to be fixed on stationary plane by multiple bolts;Work as nothing
After man-machine recyclable device is in contraction state, by the support frame 23 that is fixed on stationary plane to unmanned plane recyclable device front into
Row support.The bottom surface of support frame 23 is equipped with multiple threaded connection holes II 18, to be fixed on stationary plane by multiple bolts.
To sum up, by flexible 1 pitching of arm assembly to certain angle, the arm assembly 1 that stretches is synchronous to be stretched out amplitude oil cylinder I 8.According to
The collapsing length of different types, the arm assembly 1 that stretches is adjustable.Amplitude oil cylinder II 9 will fold 2 pitching of arm assembly to certain angle
Degree, the angle can be adjusted according to different types.Amplitude oil cylinder III 10 swings to 180 degree for II 2-2 of arm is folded, structurally
The lateral length at end, that is, distance of the lanyard point apart from the centre of gyration.The brake motor that cross bar assembly 3 uses adds the mechanism of rope component,
Realize that the two-stage of cross bar is flexible.The advantages of mechanism is to occupy little space, and telescopic arm section adds rope modular construction small compared with oil cylinder.
Turntable 4, flexible arm assembly 1, folding arm assembly 2, cross bar assembly 3 constitute the space of an approximate c-type.Pass through recycling rope assembly
Two notches above and below 7 connection c-type structures, to constitute a complete unmanned aerial vehicle rope recycling space.The device withdraws shape
State space occupied is small, transport convenience, can be vehicle-mounted, can aboard ship can also use, can also fill mounted in tow out on trailer
It is transported in 20 forty equivalent unit 40s.
