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 and 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 poor, for example plastics.Flexible frame surrounding also can comprise padded coaming, inflatable packer or elastic variable pipe etc. further.Awning device also further comprises floor layer 6, wherein this floor layer is a kind of telescoping floor, it comprises a scalable portion 11, this scalable portion utilizes for example actuator in 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 to be also 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 with the floor layer 6 of awning device 1 pivotally, and between door-shaped frame 2 and stereoplasm frame 6, use energy storage equipment and reclaim winding mechanism 8, and energy storage equipment can be for example gas spring 7.Flexible frame can be articulated with the front end of the scalable portion 11 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.In each side, between stereoplasm frame 4 and flexible frame 5, be connected with a plurality of actuators (in order to adapt to various fuselage surface curvature, at cost, can accept in scope, the quantity of actuator is preferably The more the better), for example hydraulic actuator 9, consider, in the present embodiment for simplifying, the number of hydraulic actuator is herein three, and on even keel is arranged between stereoplasm frame 4 and flexible frame 5 respectively.These three actuators are preferably distributed in 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 laminating of flexible frame and fuselage cover.Actuator one end and flexible frame 5 carry out hinged, and the other end is hinged with stereoplasm frame 4.In two side ends of front end of the scalable portion 11 of floor layer (floor and flexible frame hinge-point below) and flexible frame 5 both sides branches, be also respectively arranged with distance measuring sensor 10, 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 adopt 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 the perforate on flexible frame 5, apomecometer can the deflection along with flexible frame flexural deformation.Apomecometer quantity on 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 flexible frame 5 should be alignments, that is to say that they should be arranged on same vertical straight line.Certainly, for the object of protection apomecometer, their edges should slightly retreat in the edge of flexible frame or floor layer front end, can not cause shock to apomecometer like this when docking.Apomecometer installation site in each branch of flexible frame is crisscross arranged with respect to actuator articulated position, specifically, apomecometer should be tried one's best and is arranged at dispersedly on 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, from installing space, consider it is also favourable in addition, simultaneously due to they installation of staggering, thus also less for the infringement of flexible frame.The peripheral surrounding in the space between stereoplasm frame, flexible frame and door-shaped frame is equipped with awning.Awning device 1 also comprises the controller (not shown) that is for example arranged on door-shaped frame 3 rear upper lateral parts, for receiving the signal that laser rangefinder obtains and controlling the operation of hydraulic actuator 9,12 and winding mechanism 8, go back in addition controller and also control a warning device.Therefore this controller can have following function: when boarding due to passenger, cause that connecting bridge trembles with respect to airplane skin, and then for example, give the alarm while causing connecting bridge docking framework to depart from the larger distance of fuselage cover (being 10 centimetres) and warn 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).
At length introduce the method for operating of the awning device 1 in the present invention below.
First, before awning device contacts with fuselage cover, at connecting bridge, use the initial stage, the laser rangefinder of opening on awning device is measured flexible frame apart from the distance of airframe, at connecting bridge, vertically towards aircraft, advance and (can utilize two apomecometers that are arranged at 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 that each laser rangefinder is measured are different, distance herein can be any data that measure in laser rangefinder) can be the arbitrary set point value between 0.5-5 rice time, preferably 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 flexible frame) and is carried out separately flexible with 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.First utilize the distance of the measured distance fuselage of apomecometer on flexible frame and floor layer, via controller simulation, generate the surperficial radian of the fuselage cover that will dock, as shown in mark 101; Then to this arc curve of docking framework translation (due to floor horizontal extension only) until put 107 intersection location on this camber line and flexible frame, in fact this point is can be optional, be for example 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 according to the length of flexible frame branch (because its extensibility is poor, ignoring spread length herein), can learn that 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 hydraulic actuator of the present invention can realize flexible frame after distortion can have with will in conjunction with the identical radian of fuselage cover.Mark in this figure 103,104,105 is the flexible frame in 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 auxiliary actuator (not shown) between actuator and stereoplasm frame, because the deflection angle of simulation actuator 104 in frame deformation process can calculate according to the method described above, therefore can according to calculated angle, carry out the actuator between deflection flexible frame and stereoplasm frame 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 framework both sides, the distortion that is to say flexible frame both sides can be different when needed, and this is very favorable while there is larger corner for 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 control system error due to the fault of self.
After this, continuing to 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 while fitting in fuselage cover (according to the laser rangefinder measuring distance of the scalable portion in floor front end and the comparison of anticipated value) brake connecting bridge.
Then controller is controlled winding mechanism release energy storage equipment, make it that docking framework is closely pressed on to fuselage cover, because the flexible frame in the present invention is by actuator-operated distortion, therefore the energy storage equipment in the present invention, without apply like that larger thrust in prior art, has therefore also just reduced the risk that awning device damages fuselage cover.
Passenger, board in process, because external conditions or passenger's weight extruding causes awning device with respect to fuselage cover generation deflection or disengaging, because laser rangefinder can measure the variation of distance, for example, if therefore the distance of flexible frame and fuselage cover reaches a predetermined threshold (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 in the present invention had just had the surperficial radian of fuselage cover before laminating fuselage cover, therefore can improve sealing property, reduced the hurtful risk of fuselage skin simultaneously.Also there is in addition alarm and again revise laminating degree.What below do not elaborate is all the common practise in affiliated field.
Those skilled in the art can make and replacing or modification 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 departing from the present invention's design, and these replacements or modification are all in the claimed interest field of the present invention.
