Fig. 2 has schematically simulated the mode of texturing of the flexible frame of the awning device in the present invention.
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 bridge body passageway and awning device 1, and this awning device 1 comprises door-shaped frame 2 and docking framework 3, and 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.The flexible frame surrounding also can comprise padded coaming, inflatable packer or elastic variable pipe etc. further.Flexible frame in height will be longer than stereoplasm frame, this flexible frame in the present invention is very favourable, because it has than big-length, even still can be for the passenger provides good space after therefore being out of shape, comparatively roomy flexible frame also more be conducive to docking certainly.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, can be also 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 front end sidepieces of awning device 1 pivotally, and stereoplasm frame 4 also can comprise the shutoff device that can stop its pivotable; And use energy storage equipment between door-shaped frame 2 and stereoplasm frame 6 and reclaim winding mechanism 8, energy storage equipment can be for example gas spring 7.On each side, be connected with a plurality of actuators between stereoplasm frame 4 and flexible frame 5 (in order to adapt to various fuselage surface curvature, can accept in 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 5.These 5 actuators preferably are distributed on each side of flexible frame dispersedly, but preferably have the top of 2 each side branches that are separately positioned on flexible frame in a plurality of actuator at least, are beneficial to the applying of flexible frame and fuselage cover.That is to say, the flexible frame in the present invention breaks away from floor layer, and it supports by stereoplasm frame and actuator fully, and this structure is very favourable for the distortion of flexible frame.Actuator one end and flexible frame 5 carry out hinged, the other end is hinged with stereoplasm frame 4, a but actuator near middle (being preferably in stereoplasm frame 1/4th to 3/4ths altitude ranges), for example as shown in Figure 1, it is fixedly connected on stereoplasm frame 4 again by means of detachable fixed support 14, and whole like this flexible frame just can not move up and down; Certainly, directly this actuator is fixedly connected on stereoplasm frame and also is fine, but connect by means of detachable fixed support, the support that is conducive to change different length is regulated flexible frame with respect to the height up and down of stereoplasm frame.Also be respectively arranged with a plurality of distance measuring sensors 10 in the branch of flexible frame both sides, this apomecometer can be for example 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 arranged on flexible frame, and this laser rangefinder also can be arranged among perforate on flexible frame.Apomecometer preferably disperses to be distributed on vertical height of flexible frame, and certainly, in order to measure accurately, they should be on the same vertical curve.The front end of the scalable section of floor layer also is provided with apomecometer 13.Apomecometer quantity on flexible frame can be identical from actuator quantity also can be different.Preferably, except the end of flexible frame, apomecometer installation site and the actuator hinge-point on flexible frame staggers as far as possible, so just can not cause too much infringement to flexible frame, is conducive to simultaneously the use of apomecometer.
The peripheral surrounding in the space between flexible frame and door-shaped frame is equipped with vestibule diaphragm.Vestibule diaphragm device 1 also comprises the controller (not shown) that is arranged on door-shaped frame 2 rear upper lateral parts, be used for to receive the signal that laser rangefinder obtains and the operation of controlling hydraulic actuator 9 and winding mechanism 8, goes back in addition controller and also controls a warning device.Therefore this controller can have following function: cause that when boarding due 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 (being for example 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 in 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 awning device is measured stereoplasm frame apart from the distance of airframe, vertically advance towards retractable aircraft at connecting bridge and (can utilize two apomecometers on the same level line that is arranged on flexible frame, 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 laser rangefinder on flexible frame) in the time of can being the arbitrary set point value between 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.
With reference to accompanying drawing 2, it has schematically simulated the mode of texturing of the flexible frame of the awning device in the present invention.At first utilize the measured distance apart from fuselage of apomecometer on flexible frame, generate the surperficial radian of the fuselage cover that will dock via the controller simulation, as shown in mark 101; Then to docking this arc curve of framework translation until attachment point intersection location on this camber line and flexible frame, that actuator that this attachment point namely can not pivotable and the point of connection of flexible frame.
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 distortion should be as shown in mark 102.And then after 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 in this figure, 105 respectively the flexible frame in representative simulations, initial position actuator and flexible after actuator.In this process, it is flexible that actuator that can not pivotable keeps.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 (do not comprise can not that actuator of the pivotable) 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 stereoplasm frame according to the angle of calculating with auxiliary actuator.Described computation process can be completed by controller, and relevant mathematic calculation is all 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 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 in the present invention just completed actuating before docking, can or not occur transshipping because of the control system error due to the fault of self.
After this, namely continuing to control connecting bridge advances, and when moving closer to airframe (distance measured according to apomecometer and the comparison of anticipated value) the connecting bridge speed of advance slows down, (according to the comparison of laser rangefinder measuring distance and anticipated value, this value is relevant to the apomecometer installation site) namely brakes connecting bridge until flexible frame when fitting in fuselage cover.Afterwards, the apomecometer 13 of the stronghold scalable section of flaggy front end is controlled actuator 12 elongation floor segments 11, until this floor segment and fuselage are fitted.
Then controller is controlled winding mechanism release energy storage equipment, make it will dock framework and closely be pressed on fuselage cover, due to the flexible frame in the present invention by actuator-operated distortion, therefore the energy storage equipment in 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, can measure the variation of distance due to laser rangefinder, if therefore the distance of flexible frame and fuselage cover reaches a predetermined threshold (being for example 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.
Just had the surperficial radian of fuselage cover due to the engage frame in the present invention before the applying fuselage cover, therefore can improve sealing property, reduced simultaneously the hurtful risk of fuselage skin.Also have advantages of in addition alarm and again revise the applying degree.What below do not elaborate is all 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.
