The specific embodiment
With reference to accompanying drawing 1, wherein shown the awning device 1 that comprises according to docking framework of the present invention, this awning device 1 comprises door-shaped frame 2 and docking framework 3, docking framework 3 is directly used in realizes docking of awning device 1 and airframe shell.Docking framework 3 comprises stereoplasm frame 4 and the flexible frame 5 that will directly contact with fuselage cover, and flexible frame 5 is made by flexible material, but the ductility of this material is relatively poor, for example plastics.Also can comprise further padded coaming, inflatable packer or elastic variable pipe etc. around the flexible frame.Awning device also further comprises floor layer 6, wherein this floor layer is a kind of telescoping floor, it comprises one scalable 11, this scalable utilization for example is in the actuator of floor layer inside, for example hydraulic actuator 12 is realized fore and aft motion, this hydraulic actuator 12 is arranged at of floor layer midway location, also can be to be arranged at respectively two of two ends, and can certainly be other quantity.Door-shaped frame 2 is fixedly connected on floor layer 6.4 of stereoplasm frames are articulated in the floor layer 6 of awning device 1 pivotally, and use energy storage equipment between door-shaped frame 2 and the stereoplasm frame 6 and reclaim winding mechanism 8, and energy storage equipment for example can be gas spring 7.Flexible frame can be articulated in scalable 11 the front end on floor, but as a kind of selection, also can be fixedly installed on this expansion floor.In order to be added to open area, preferably, stereoplasm frame 4 and flexible frame also can be arranged on the lateral surface of floor layer.On each side, be connected with a plurality of actuators between stereoplasm frame 4 and the flexible frame 5 (in order to adapt to various fuselage surface curvature, can accept in the scope at cost, the quantity of actuator is preferably The more the better), for example hydraulic actuator 9, consider for simplifying, in the present embodiment, the number of hydraulic actuator herein is three, and on even keel is arranged between stereoplasm frame 4 and the flexible frame 5 respectively.These three actuators preferably are distributed on each side of flexible frame dispersedly, but the rarest top that is arranged on each side branch of flexible frame preferably in a plurality of actuator is beneficial to the applying of flexible frame and fuselage cover.Actuator one end and flexible frame 5 carry out hinged, and the other end is then hinged with stereoplasm frame 4.Also be respectively arranged with distance measuring sensor 10 in two side ends of the front end that floor layer is scalable 11 (floor and flexible frame hinge-point below) and the flexible frame 5 both sides branches, this apomecometer can for example be ultrasonic range finder, infrared ambulator or laser rangefinder, the preferential laser rangefinder of selecting in the present embodiment.The installation of apomecometer on flexible frame can be adopted well-known conventional means, for example can adopt the form of support to be installed on the flexible frame, and this laser rangefinder also can be arranged among the perforate on the flexible frame 5, and apomecometer can the deflection along with flexible frame flexural deformation.Apomecometer quantity on the flexible frame can be identical from actuator quantity also can be different.The set laser rangefinder of floor layer front end can be arranged in the boring of floor layer front end.Under initial condition, distance measuring sensor 10 in the vertical directions that arrange on floor layer front end and the flexible frame 5 should be alignments, that is to say that they should be arranged on the same vertical straight line.Certainly, for the purpose of protection apomecometer, their edges should slightly retreat in the edge of flexible frame or floor layer front end, can not cause bump to apomecometer like this when docking.Apomecometer installation site in each branch of flexible frame is crisscross arranged with respect to the actuator articulated position, specifically, apomecometer should be tried one's best and is arranged at dispersedly on the flexible frame, but should avoid being in the hinge-point of very close actuator on flexible frame, this use for apomecometer is very favourable, therefore described hinge-point often suffers stress, this is unsafe for apomecometer, consider it also is favourable from installing space in addition, the simultaneously installation because they stagger, therefore also less for the infringement of flexible frame.Be equipped with awning around the periphery in the space between stereoplasm frame, flexible frame and the door-shaped frame.Awning device 1 also comprises the controller (not shown) that for example is arranged on door-shaped frame 3 rear upper lateral parts, be used for to receive signal that laser rangefinder obtains and control hydraulic actuator 9,12 and the operation of winding mechanism 8, go back in addition controller and also control a warning device.Therefore this controller can have following function: cause that when boarding owing to the passenger connecting bridge trembles with respect to airplane skin, and then give the alarm when causing the connecting bridge docking larger distance of framework detachment machine body shell (for example being 10 centimetres) and warn the passenger to postpone action, and again start wind2 release energy storage equipment or primer fluid hydraulic actuator, until measuring distance, laser rangefinder reenters safe range (sounding all clear).
The below at length introduces the method for operating of the awning device 1 among the present invention.
At first, at awning device with before fuselage cover contacts, use the initial stage at connecting bridge, the laser rangefinder of opening on the awning device is measured flexible frame apart from the distance of airframe, vertically advance towards aircraft at connecting bridge and (can utilize two apomecometers that are arranged at the floor layer leading section, if the distance of their two measurements equates, illustrate that connecting bridge just vertically advances towards aircraft), and when approaching the aircraft certain distance that will dock, this distance is (because aircraft surfaces is arc line shaped, therefore the data of each laser rangefinder measurement are different, distance herein can be any data that measure in the laser rangefinder) in the time of can being the arbitrary set point value between the 0.5-5 rice, preferred 1 meter, temporarily stop connecting bridge near the motion of aircraft, the distance value that controller measures according to each laser rangefinder is controlled each actuator (comprising the whole apomecometers and the actuator that are arranged on floor layer and the flexible frame) and is carried out separately flexible with the distortion flexible frame.
With reference to accompanying drawing 2, it has schematically simulated the mode of texturing of the flexible frame of the awning device among the present invention.At first utilize the measured distance apart from fuselage of apomecometer on flexible frame and the floor layer, generate the fuselage cover surface radian that will dock via the controller simulation, shown in mark 101; Then to this arc curve of docking framework translation (because floor only horizontal extension) until put 107 intersection location on this camber line and the flexible frame, in fact this point is can be optional, for example be flexible frame mid point or 2/3rds At The Heights, preferred mode is to save the momentum of doing of actuator as far as possible.Therefore can learn that according to the length (because its extensibility is poor, ignoring spread length herein) of flexible frame branch the flexible frame after the distortion should be shown in mark 102 like that.And then after the distortion, (stereoplasm frame 106 of simulation keeps motionless) elongation or retracted length of associated actuator just can calculate.Subsequently controller according to aforementioned calculated amount activate flexible frame after hydraulic actuator of the present invention can be realized being out of shape can have with will in conjunction with the identical radian of fuselage cover.Mark 103,104 among this figure, 105 is the flexible frame in the representative simulations, the actuator after flexible and the actuator of initial position respectively.In addition, in order more accurately to guarantee the distortion of flexible frame, the present invention can also arrange the auxiliary actuator (not shown) between actuator and stereoplasm frame, because the simulation deflection angle of actuator 104 in the frame deformation process can calculate according to the method described above, therefore can come actuator between deflection flexible frame and the stereoplasm frame according to the angle of calculating with auxiliary actuator.Described computation process can be finished by controller, and relevant mathematic calculation all is the common practise in affiliated field.
In this process, independent operation can be distinguished in the framework both sides, the distortion that is to say the flexible frame both sides can be different when needed, and this is very favorable when larger corner occurring for the hatch door periphery, so the present invention has very outstanding alerting ability in docking operation.Therefore and the actuator among the present invention just finished actuating before docking, can not occur transshipping owing to the fault of self or because of the control system error.
After this, namely continuing the control connecting bridge advances, and (the laser rangefinder measuring distance of stronghold front edge of board and the comparison of anticipated value when moving closer to airframe, described anticipated value is relevant with respect to the installation site at flexible frame edge with apomecometer) the connecting bridge speed of advance that slows down, until flexible frame when fitting in fuselage cover (according to the laser rangefinder measuring distance of scalable the front end in floor and the comparison of anticipated value) brake connecting bridge.
Then controller control winding mechanism discharges energy storage equipment, make it will dock framework and closely be pressed on fuselage cover, because the flexible frame among the present invention is by actuator-operated distortion, therefore the energy storage equipment among the present invention need not to apply like that larger thrust in prior art, has therefore also just reduced the risk that awning device damages fuselage cover.
In the passenger boards process, because the extruding of external conditions or passenger's weight causes awning device with respect to fuselage cover generation deflection or disengaging, because laser rangefinder can measure the variation of distance, if therefore the distance of flexible frame and fuselage cover reaches a predetermined threshold (for example being 10 centimetres), controller can be controlled accordingly warning device and give the alarm, and again start wind2 release energy storage equipment or primer fluid hydraulic actuator, until measuring distance, laser rangefinder reenters safe range.
Because the engage frame among the present invention had just had the surperficial radian of fuselage cover before the applying fuselage cover, therefore can improve sealing property, reduced simultaneously the hurtful risk of fuselage skin.Also have in addition alarm and again revise the advantage of applying degree.What below do not elaborate all is the common practise in affiliated field.
Those skilled in the art can make replacement or modification to content of the present invention according to content disclosed by the invention and the art technology of grasping; but these replacements or modification should not be considered as breaking away from the present invention's design, and these replacements or modification are all in the claimed interest field of the present invention.
