With reference to accompanying drawing 1, it partially show according to connecting bridge of the present invention, it comprises scalable 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 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 high extensibility, highly elastic material, such as but be not restricted to elastomeric material.Flexible frame surrounding also can comprise padded coaming, inflatable packer or elastic variable pipe etc. further.Awning device also comprises floor layer 6 further, wherein this floor layer is a kind of telescoping floor, it comprises a telescoping section 11, this telescoping section utilizes the actuator being such as in floor layer inside, such as hydraulic actuator 12 realizes fore and aft motion, this hydraulic actuator 12 is arranged at one of floor layer midway location, and also can be two that are arranged at two ends respectively, can certainly be other quantity.Door-shaped frame 2 is fixedly connected on floor layer 6.Stereoplasm frame 4 is articulated with the floor layer 6 of awning device 1 pivotally, and uses energy storage equipment between door-shaped frame 2 and stereoplasm frame 6 and reclaim winding mechanism 8, and energy storage equipment can be such as gas spring 7.Flexible frame can be articulated with the front end of the telescoping section 11 on floor, but selects as a kind of, 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, 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 herein three, and on even keel is arranged between stereoplasm frame 4 and flexible frame 5 respectively.These three actuators are preferably evenly distributed on every side of flexible frame, but the preferably the rarest top being arranged on every side branch of flexible 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, the front end side end of floor layer telescoping section 11 (floor and flexible frame hinge-point below) and flexible frame 5 both sides branch are also respectively arranged with distance measuring sensor 10, this apomecometer can be such as ultrasonic range finder, infrared ambulator or laser rangefinder, prioritizing selection laser rangefinder in the present embodiment.The installation of apomecometer on flexible frame can adopt well-known conventional means, the form of support such as can be adopted to be arranged on flexible frame, and apomecometer such as can realize remaining level when flexible frame bends by means of surface level-meter and micro-actuator, this means are described field conventional techniques means, repeat no more herein; And this laser rangefinder also can be arranged among the perforate on flexible frame 5.The set laser rangefinder of floor layer front end can be arranged in the boring of floor layer front end.In an initial condition, distance measuring sensor 10 in the vertical direction that floor layer front end and flexible frame 5 are arranged should be alignment, and that is they should be arranged on same vertical straight line.Certainly, for the object of protection apomecometer, their edges slightly should retreat the edge in flexible frame or floor layer front end, can not cause shock like this when docking to apomecometer.Except being arranged at the laser rangefinder of floor layer, the quantity of actuator 9 is identical with the quantity of remaining laser rangefinder, and be arranged at corresponding apomecometer side respectively singly, hinge-point and the laser rangefinder attachment point of mutual contiguous actuator and flexible frame should remain essentially on same horizon.The periphery in stereoplasm frame, space between flexible frame and door-shaped frame is equipped with awning.Awning device 1 also comprises the controller (not shown) being such as arranged on door-shaped frame 3 upper back, for receiving the signal and the operation of hydraulic control actuator 9 and winding mechanism 8 that laser rangefinder obtains, going back controller in addition and also controlling a warning device.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).Connecting bridge in the present invention is a kind of retractable boarding bridge comprising roller.
Introduce the method for operating of the connecting bridge that the present invention includes awning device below in detail.
First, before awning device contacts with fuselage cover, the initial stage is used at connecting bridge, the laser rangefinder opened on awning 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, 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 one in laser rangefinder data of measuring) when can be 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 (comprise and be arranged at whole apomecometer on floor layer and flexible frame and actuator) according to the distance value that each laser rangefinder measures and carries out respective flexible with yielding flexibility framework.When actuator dilatation flexible frame, with the minor increment measured by each laser rangefinder for benchmark, keep actuator (actuator 12 be considered to the apomecometer of floor layer telescoping section front end adjoining actuator) the not start contiguous with this apomecometer, and the distance measured by other laser rangefinders and said reference are compared judge that adjoining actuator should be and launch or bounce back and (be greater than benchmark namely to stretch, be less than benchmark namely to bounce back), and the distance that the stadia surveying that Real-Time Monitoring is contiguous when actuator launches or bounce back arrives, this actuator is braked when distance equals benchmark, until when distance measured by the laser rangefinder of the distance that arrives of each stadia surveying and floor layer front end is identical, all actuators also all stop, thus the flexible frame realized after distortion has identical surface curvature with the fuselage cover that will dock.Also the maximum distance measured can be adopted to be benchmark, and just actuator stretches contrary with retraction aforesaid way.In this process, framework both sides can 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 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 (according to the laser rangefinder measuring distance of telescoping section front end, floor and comparing of anticipated value) brakes connecting bridge when flexible frame fits in fuselage cover.If now occur the distance that respective laser stadia surveying arrives and anticipated value gap larger time, again can adjust adjacent actuator start, until enter preset range.
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 awning device damages fuselage cover.
In passenger's boarding process, because the weight extruding of external conditions or passenger causes awning 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 laser rangefinder again starts wind2 release energy storage equipment or primer fluid hydraulic actuator, until can measure distance reenter safe range.
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.
