Detailed description of the invention

With reference to accompanying drawing 1, it partially show according to connecting bridge of the present invention, and the connecting bridge in the present invention is a kind of retractable boarding bridge comprising roller.It comprises 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 and realizes docking of vestibule diaphragm device 1 and aircraft fuselage cover.The flexible frame 5 that docking framework 3 comprises stereoplasm frame 4 and directly will contact with fuselage cover, flexible frame 5 is made up of flexible material, but the ductility of this material is poor, such as plastics.Flexible frame surrounding also can comprise padded coaming, inflatable packer or elastic variable pipe etc. further.Door-shaped frame 2 is fixedly connected on floor layer 6.Described floor layer is the non-telescoping formula flaggy regularly that cannot change shape.Stereoplasm frame 4 is articulated with the floor layer 6 of vestibule diaphragm 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 such as gas spring 7.Flexible frame can be fixedly installed on floor, but selects as a kind of, also can be articulated with 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, multiple actuator is connected with (in order to various fuselage surface curvature can be adapted between stereoplasm frame 4 and flexible frame 5, can accept in scope at cost, the quantity of actuator is preferably The more the better), such as hydraulic actuator 9, considers for simplification, in the present embodiment, the number of hydraulic actuator is four, and on even keel is arranged between stereoplasm frame 4 and flexible frame 5 respectively.These four actuators are preferably distributed on every side of stereoplasm frame dispersedly, but the preferably the rarest top being arranged on every side branch of stereoplasm frame in multiple actuator, be 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 then hinged with stereoplasm frame 4.Two, floor layer front end sidepiece and stereoplasm frame 4 both sides branch are also respectively arranged with distance measuring sensor 11,10, this apomecometer can be such as ultrasonic range finder, infrared ambulator or laser rangefinder, prioritizing selection laser rangefinder in the present embodiment, the apomecometer that two, floor layer front end sidepiece is installed is very favourable for later stage docking.The installation of apomecometer on stereoplasm frame 4 can adopt well-known conventional means, such as, the form of support can be adopted to be arranged on stereoplasm frame 4, and this laser rangefinder also can be arranged among the perforate on stereoplasm frame 4.Apomecometer quantity on stereoplasm frame 4 can 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 as schematically shown in Figure 2, the lateral branching of stereoplasm frame 4 on width outline wider than flexible frame 5, such actuator attachment point and apomecometer attachment point stagger on the width of framework branch, thus make flexible frame can not stop the light of apomecometer, if certainly the actuator attachment point on stereoplasm frame is drawn a straight line, the words that 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 bottom, apomecometer also should disperse on stereoplasm frame as far as possible (being preferably evenly) installs (due to floor being provided with apomecometer, without the need to installing near therefore bottom stereoplasm frame) again, is beneficial to the surperficial radian obtaining fuselage cover accurately.Apomecometer on stereoplasm frame should be on same vertical curve.The periphery in stereoplasm frame, space between flexible frame and door-shaped frame is equipped with vestibule diaphragm.Vestibule diaphragm device 1 also comprises the controller (not shown) being arranged on door-shaped frame 3 upper back, and for receiving the signal and the operation of hydraulic control actuator 9 and winding mechanism 8 that laser rangefinder obtains, controller also controls a warning device in addition.Therefore this controller can have following function: when causing connecting bridge to tremble relative to airplane skin due to passenger's boarding, and then the warning passenger that gives the alarm when causing connecting bridge docking framework to depart from fuselage cover larger distance (being such as 10 centimetres) postpones action, and laser rangefinder again starts wind2 release energy storage equipment or primer fluid hydraulic actuator, until can measure distance reenter safe range (sounding all clear).

Introduce the method for operating of the connecting bridge in the present invention below in detail.

First, before connecting bridge contacts with fuselage cover, the initial stage is used at connecting bridge, the laser rangefinder opened on vestibule diaphragm device measures the distance of flexible frame distance airframe, connecting bridge vertically retractable aircraft advance (two apomecometers being arranged at floor layer leading section can be utilized, if their two distances measured are equal, connecting bridge just vertically aircraft advance is described), and when close to the aircraft certain distance that will dock, when this distance (can being obtained by the apomecometer being arranged at floor layer leading section) can be the arbitrary set point value between 0.5-5 rice, preferably 1 meter, temporary transient stopping connecting bridge is near the motion of aircraft, controller controls each actuator according to the distance value that each laser rangefinder measures and carries out respective stretching with yielding flexibility framework.Concrete operation method is as follows:

With reference to accompanying drawing 3, it schematically simulates the mode of texturing of the flexible frame of the vestibule diaphragm device in the present invention.First the distance (when the distance that laser rangefinder 11 measures should add initial between apomecometer 10 and 11 distance) in the horizontal direction of the distance fuselage measured by the apomecometer on stereoplasm frame and floor layer is utilized, the fuselage cover surface radian that will dock is generated, as marked shown in 101 via controller simulation; Because the flexible frame in the present invention is fixedly connected on floor, therefore flexible frame position bottom remains unchanged after deformation, therefore according to the above-mentioned radian calculated, flexible frame after known distortion divides and prevaricates as marked as shown in 102 (translation radian 101, and can draw in conjunction with the initial longitudinally height of flexible frame); Because the stereoplasm frame 106 of simulation keeps motionless, and the hinge-point position of actuator on flexible frame is fixed, and flexible frame longitudinally extends negligible, and associated extension or the retracted length of the actuator therefore after distortion just can calculate.And then controller according to aforementioned calculated amount activate hydraulic actuator of the present invention can realize the flexible frame after being out of shape can have with will in conjunction with the identical radian of fuselage cover.Mark 103,104,105 in this figure flexible frame respectively in representative simulation, flexible after actuator and the actuator of initial position.In addition, in order to the distortion of flexible frame more accurately can be guaranteed, 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, auxiliary actuator therefore can be used according to calculated angle to deflect the actuator between flexible frame and stereoplasm frame.Described computation process can be completed by controller, and relevant mathematic calculation is all the common practise in affiliated field.

In this process, framework both sides independently operate, that is the distortion of flexible frame both sides can be different when needed, and this is for being very favorable during the corner that the appearance of hatch door periphery is larger, and therefore the present invention has very outstanding alerting ability and comformability in docking operation.And the actuator in the present invention just completed actuating before docking, therefore overload can not be there is due to the fault of self or because of control system error.

After this, namely continue to control connecting bridge to advance, and (the laser rangefinder measuring distance of stronghold front edge of board and comparing of anticipated value when moving closer to airframe, described anticipated value is relevant relative to the installation site at flexible frame edge with apomecometer) slow down connecting bridge speed of advance, until (the laser rangefinder measuring distance of stronghold front edge of board and comparing of anticipated value) brakes connecting bridge when flexible frame fits in fuselage cover.

Then controller controls winding mechanism release energy storage equipment, make it that docking framework is closely pressed on 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 the need to applying larger thrust in the prior art, therefore also just reduces the risk that vestibule diaphragm device damages fuselage cover.

In passenger's boarding process, because the weight extruding of external conditions or passenger causes vestibule diaphragm device relative to fuselage cover generation deflection or disengaging, because laser rangefinder can measure the change of distance, if therefore the distance of flexible frame and fuselage cover reaches a predetermined threshold (being such as 10 centimetres), controller can control warning device accordingly and give the alarm, and again start wind2 release energy storage equipment or primer fluid hydraulic actuator, until laser rangefinder can measure distance reenter safe range, sound all clear.

Because the engagement frame in the present invention was just provided with the surperficial radian of fuselage cover before laminating fuselage cover, therefore, it is possible to improve sealing property, reduce the hurtful risk of fuselage skin simultaneously.Also there is alarm in addition and again revise the advantage of laminating degree.What below do not elaborate is all the common practise in affiliated field.

Those skilled in the art can make replacement or modification according to content disclosed by the invention and the art technology grasped to content of the present invention; but these replacements or modification should not be considered as disengaging the present invention design, and these replacements or modification are all in the interest field of application claims protection.
