Detailed description of the invention
With reference to accompanying drawing 1, it partially show according to the retractable boarding bridge comprising roller 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 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.Flexible frame in height will be longer than stereoplasm frame, this flexible frame in the present invention is very favourable, because it has greater depth, even if still can provide good space for passenger after being therefore out of shape, certainly comparatively roomy flexible frame is also more conducive to docking.Awning device also comprises telescopically flaggy 6 further, wherein this telescopically flaggy is a kind of telescoping floor, it comprises a telescoping section 11, this telescoping section utilizes the actuator being such as in telescopically flaggy inside, such as hydraulic actuator 12 realizes fore and aft motion, this hydraulic actuator 12 is arranged at one of telescopically flaggy 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 telescopically flaggy 6.Stereoplasm frame 4 is articulated with the telescopically flaggy 6 scalable front end sidepiece 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 4 and reclaim winding mechanism 8, energy storage equipment can be such as gas spring 7.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, consider for simplification, in the present embodiment, the number of hydraulic actuator is herein 5.These 5 actuators are preferably distributed on every side of flexible frame dispersedly, but preferably have 2 tops being separately positioned on every side branch of flexible frame in multiple actuator at least, are beneficial to the laminating of flexible frame and fuselage cover.That is, the flexible frame in the present invention departs from floor layer, and it is supported by stereoplasm frame and actuator completely, 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 then hinged with stereoplasm frame 4, but near an actuator of middle (being preferably in stereoplasm frame 3/1 to four/4ths altitude range), such 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 is also fine, but connect by means of detachable fixed support, be then conducive to the support of replacing different length to regulate flexible frame relative to the upper-lower height of stereoplasm frame.Flexible frame both sides branch is also respectively arranged with multiple distance measuring sensor 10, and 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, such as, the form of support can be adopted to be arranged on flexible frame, and this laser rangefinder also can be arranged among the perforate on flexible frame.Apomecometer preferably disperses to be distributed on longitudinal height of flexible frame, and certainly, in order to measure accurately, they should be on same vertical curve.The front end of floor layer telescoping section is also provided with apomecometer 13.Apomecometer quantity on flexible frame can 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, would not cause too much infringement like this, be conducive to the use of apomecometer simultaneously to flexible frame.
The periphery 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) being arranged on door-shaped frame 2 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).
Introduce the method for operating of the connecting bridge in the present invention 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 stereoplasm frame distance airframe, connecting bridge vertically retractable aircraft advance and (two apomecometers on the same level line that is arranged on flexible frame 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 the laser rangefinder on flexible frame 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 according to the distance value that each laser rangefinder measures and carries out respective stretching with yielding flexibility framework.
With reference to accompanying drawing 2, it schematically simulates the mode of texturing of the flexible frame of the awning device in the present invention.First utilizing the distance of the distance fuselage measured by the apomecometer on flexible frame, generating the fuselage cover surface radian that will dock via controller simulation, as marked shown in 101; Then to this arc curve of docking framework translation until attachment point intersection location on this camber line and flexible frame, this attachment point i.e. point of connection of that actuator not pivotable and flexible frame.
Therefore the flexible frame after can learning distortion according to the length (because its extensibility is poor, ignoring spread length herein) of flexible frame branch should as marked as shown in 102.And then after distortion, elongation or the retracted length of (stereoplasm frame 106 of simulation keeps motionless) associated actuator just can calculate.Subsequently 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.Flexible frame, the actuator of initial position and the actuator after stretching in mark 103,104,105 difference representative simulation in this figure.In this process, that actuator not pivotable keeps not stretching.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 (not comprising that actuator not pivotable) 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 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 (distance measured by apomecometer compares with anticipated value) slow down connecting bridge speed of advance when moving closer to airframe, (according to comparing of laser rangefinder measuring distance and anticipated value, this value is relevant to apomecometer installation site) namely brakes connecting bridge until when flexible frame fits in fuselage cover.Afterwards, the apomecometer 13 of flaggy front end, stronghold telescoping section, controls actuator 12 and extends floor segment 11, until this floor segment and fuselage are fitted.
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.
