The specific embodiment
With reference to accompanying drawing 1, it has partly shown the retractable boarding bridge that comprises roller according to of the present invention, it comprises scalable bridge body passageway and awning device 1, and this vestibule diaphragm device 1 comprises door-shaped frame 2 and docking framework 3, and docking framework 3 is directly used in realizes docking of vestibule diaphragm 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.Door-shaped frame 2 is fixedly connected on floor layer 6.Described floor layer is the non-telescoping formula flaggy regularly that can't change shape.4 of stereoplasm frames are articulated in the floor layer 6 of vestibule diaphragm device 1 pivotally, and stereoplasm frame 4 also can comprise the shutoff device that can stop its pivot; And use energy storage equipment between door-shaped frame 2 and the stereoplasm frame 6 and reclaim winding mechanism 8, energy storage equipment for example can be gas spring 7.Flexible frame can be fixedly installed on the floor, but as a kind of selection, also can be articulated in the front end on 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 is four, and on even keel is arranged between stereoplasm frame 4 and the flexible frame 5 respectively.These four actuators are preferably on each side that is distributed in dispersedly stereoplasm frame, but the rarest top that is arranged on each side branch of stereoplasm 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 11,10 in two sidepieces of floor layer front end and the stereoplasm frame 4 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 apomecometer that two sidepieces of floor layer front end are installed is very favourable for the later stage docking.The installation of apomecometer on stereoplasm frame 4 can be adopted well-known conventional means, for example can adopt the form of support to be installed on the stereoplasm frame 4, and this laser rangefinder also can be arranged among the perforate on the stereoplasm frame 4.Apomecometer quantity on the stereoplasm frame 4 can be identical from actuator quantity also can be different.The set laser rangefinder of floor layer front end sidepiece can be arranged in the boring of floor layer front end.Their setting position is such as schematically shown in Figure 2, the lateral branching of stereoplasm frame 4 outline on width is wider than flexible frame 5, actuator attachment point and apomecometer attachment point stagger at the width of framework branch like this, thereby so that flexible frame can not stop the light of apomecometer, if certainly the actuator attachment point on the stereoplasm frame is drawn a straight line, the words that the apomecometer attachment point also draws a straight line, these two straight lines also should be tried one's best close, are beneficial to the radian simulation in later stage.Except the bottom, apomecometer also should disperse (being preferably evenly) that (because the floor is equipped with apomecometer, so need not to install near the stereoplasm frame bottom) is installed again on stereoplasm frame as far as possible, is beneficial to obtain accurately the surperficial radian of fuselage cover.Apomecometer on the stereoplasm frame should be on the same vertical curve.Be equipped with vestibule diaphragm around the periphery in the space between stereoplasm frame, flexible frame and the door-shaped frame.Vestibule diaphragm device 1 also comprises the controller (not shown) that is arranged on door-shaped frame 3 rear upper lateral parts, be used for to receive signal that laser rangefinder obtains and the operation of control hydraulic actuator 9 and winding mechanism 8, and controller is also controlled a warning device in addition.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 connecting bridge among the present invention.
At first, at the vestibule diaphragm device with before fuselage cover contacts, use the initial stage at connecting bridge, the laser rangefinder of opening on the vestibule diaphragm device is measured flexible frame apart from the distance of airframe, vertically advance towards retractable 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 (can be obtained by the apomecometer that is arranged at the floor layer leading section) is 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 and is carried out separately flexible with the distortion flexible frame.Concrete operation method is as follows:
With reference to accompanying drawing 3, it has schematically simulated the mode of texturing of the flexible frame of the vestibule diaphragm device among the present invention.At first utilize the measured distance apart from fuselage of apomecometer on stereoplasm frame and the floor layer (distance that laser rangefinder 11 measures should add when initial between the apomecometer 10 and 11 distance in the horizontal direction), generate the fuselage cover surface radian that will dock via the controller simulation, shown in mark 101; Because the flexible frame among the present invention is fixedly connected on the floor, therefore flexible frame bottom position after distortion remains unchanged, therefore according to the above-mentioned radian that calculates, flexible frame after the distortion divides and prevaricates shown in mark 102 like that (translation radian 101, and can draw in conjunction with the initial vertically height of flexible frame) as can be known; Because it is motionless that the stereoplasm frame 106 of simulation keeps, and the hinge-point position of actuator on flexible frame fix, and the vertical extension of flexible frame can ignore, and therefore relevant elongation or the retracted length of the actuator after the distortion just can calculate.And then 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, the framework both sides are independent operation respectively, 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 and comformability 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 (the laser rangefinder measuring distance of stronghold front edge of board 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 the vestibule diaphragm device damages fuselage cover.
In the passenger boards process, because the extruding of external conditions or passenger's weight causes the vestibule diaphragm 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 and discharge energy storage equipment or primer fluid hydraulic actuator, reenter safe range until laser rangefinder can measure distance, sound all clear.
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.
