Description
Technical field
The present invention relates to fuselage transport trolley air conducting physical construction in a kind of aircraft.Belong to aerodynamic scope.
Background technology
In aircraft, fuselage transport trolley is in the process of running at high speed, because after middle fuselage loading, whole height is higher, and likely meet with the inclement weathers such as strong wind in long-distance transport process, now in transit by the service direction windage under the effect of car Wind Field and lateral loading very large, may impact by centering fuselage, make middle fuselage stress deformation, also can form certain threat to the driving safety of transport trolley simultaneously.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, fuselage transport trolley air conducting physical construction in a kind of aircraft is provided, its structure is simple, easy to operate, water conservancy diversion Be very effective, effectively can reduce the application force of air resistance centering fuselage, reduce resistance when transport trolley travels simultaneously, prevent the excessive transport trolley that causes of windage from tumbling.
The object of the present invention is achieved like this: fuselage transport trolley air conducting physical construction in a kind of aircraft, it comprises the anterior guiding device be arranged on gooseneck and the middle part guiding device be arranged on middle vehicle frame, described anterior guiding device comprises streamlined reefer housing, bearing pin and extensible link, one end of described streamlined reefer housing is articulated with the top of gooseneck, one end and the gooseneck of described extensible link are hinged, and the other end and streamlined reefer housing are hinged by bearing pin; Described middle part guiding device comprises upset shelter, upset hydraulic actuating cylinder, expansion hydraulic actuating cylinder and expansion guar plate, the side of described upset shelter and the sliding guide of middle vehicle frame both sides are hinged, described sliding guide is connected with middle vehicle frame by guideway, one end of described upset hydraulic actuating cylinder is fixed on middle vehicle frame, the other end is connected with upset shelter, described expansion hydraulic actuating cylinder one end is connected with middle vehicle frame, and the other end is connected with sliding guide, and described expansion guar plate is by hinge both sides above middle vehicle frame.
Angle between described streamlined reefer housing and gooseneck is 0-90 °.
Compared with prior art, the present invention has following beneficial effect:
The present invention is when loading fuselage in aircraft, and the streamlined reefer housing above body forward structure can make front act directly on airflow function on middle fuselage on streamlined reefer housing, and centering fuselage plays a protective role, and during empty wagons, streamlined reefer housing is regained, and reduces the windage of direction of traffic; When wind direction and vehicle heading at an angle time, streamlined reefer housing declines, now side-overturning shelter and bottom are expanded guar plate fraction can be made to fall along shelter sidewall and guar plate water conservancy diversion, effectively improve the kinematics characteristic of vehicle body Wind Field, the aerodynamic characteristic of Optimizing Transport car, reduce the injury of air resistance to fuselage in aircraft, effectively protect fuselage in aircraft; After expansion hydraulic actuating cylinder stretches out, expansion guar plate adds the width of vehicle, to the transport trolley of running at high speed, there is aerofoil effect, change the airflow field structure around transport trolley, the aerodynamic characteristic of Optimizing Transport car, effectively reduce windage, there is anti-tipping effect, add riding stability and the drive safety of vehicle.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of middle front part guiding device of the present invention.
Fig. 2 is the scheme of installation of middle part guiding device in the present invention.
Wherein:
Streamlined reefer housing 1, bearing pin 2, extensible link 3, gooseneck 4, upset shelter 5, upset hydraulic actuating cylinder 6, expansion hydraulic actuating cylinder 7, expansion guar plate 8, middle vehicle frame 9, sliding guide 10.
Detailed description of the invention
See Fig. 1-Fig. 2, the present invention relates to fuselage transport trolley air conducting physical construction in a kind of aircraft, comprise the anterior guiding device be arranged on gooseneck 4 and the middle part guiding device be arranged on middle vehicle frame 9, described anterior guiding device comprises streamlined reefer housing 1, bearing pin 2 and extensible link 3; Described middle part guiding device comprises upset shelter 5, upset hydraulic actuating cylinder 6, expansion hydraulic actuating cylinder 7 and expansion guar plate 8.
One end of described streamlined reefer housing 1 is articulated with the top of gooseneck 4, can regulate with the luffing angle of gooseneck 4, can realize upset by bearing pin 2 and extensible link 3.When loading fuselage in aircraft, described streamlined reefer housing 1 is adjusted with the angle of gooseneck 4 extremely close to 90 ° by bearing pin 2 and extensible link 3, now streamlined reefer housing 1 is angularly larger with gooseneck 4 institute, front can be made to act directly on airflow function on middle fuselage on described streamlined reefer housing 1, effectively can reduce the effect of air resistance to fuselage in aircraft, fuselage in protection aircraft; During empty wagons, described streamlined reefer housing 1 adjusts with the angle of gooseneck 4 extremely close to 0 ° by bearing pin 2 and extensible link 3, and now streamlined reefer housing 1 is angularly less with gooseneck 4 institute, thus reduces windage.
The side of described upset shelter 5 and the sliding guide 10 of middle vehicle frame 9 both sides are hinged, described sliding guide 10 is connected with middle vehicle frame 9 by guideway, one end of described upset hydraulic actuating cylinder 6 is fixed on middle vehicle frame 9, the other end is connected with upset shelter 5, upset shelter 5 can be made to rotate around bottom bearing pin by the flexible of upset hydraulic actuating cylinder 6, described expansion hydraulic actuating cylinder 7 one end is connected with middle vehicle frame 9, the other end is connected with sliding guide 10, upset shelter 5 entirety can be made to move to middle vehicle frame 9 outside direction by the flexible of expansion hydraulic actuating cylinder 7, described expansion guar plate 8 by hinge on middle vehicle frame 9, near upset shelter 5, be arranged in both sides above vehicle frame 9, described expansion guar plate 8 can keep flat after upset shelter 5 outwards translation, a plane is fixedly connected to form with middle vehicle frame 9, transport trolley surrounding flow field structure can be improved, the aerodynamic characteristic of Optimizing Transport car, water conservancy diversion falls air effectively, reduce windage.
