Abstract
The invention provides a novel mounting and maintaining structure of an oil tank. An inclined supporting rod structure with connectors and angle pieces instead of an intrinsical conventional steel pipe structure is adopted on one side of a steel framework, angle box structures are additionally weld to a steel pipe, and the angle box structures and the inclined supporting rod are connected and fixed through fasteners, so that a dismountable structure with a communicating function is realized. The novel mounting and maintaining structure is simple in structure, good in reliability and easy to operate.
Description
Technical field
The present invention relates to a kind of fuel tank installation and maintenance structure, belong to fuel tanker and safeguard field of mechanical technique.
Background technology
Fuel tank is the pith of aircraft, is the unique storage place of aircraft flight fuel, is usually located at fuselage interior, occupies fuselage Steel Structure major part space.Thus in aircraft assembling and maintenance process, complicated access structure can cause holistic cost to rise, and also can cause difficulty to the maintenance of aircraft simultaneously, even can have influence on the attendance rate of aircraft.
Summary of the invention
For solving the installation and maintenance problem of fuel tank, the invention provides that a kind of structure is simple, good reliability, easy-to-operate new-type fuel tank installation and maintenance structure.
The present invention is realized by following technical proposals, a kind of new-type fuel tank installation and maintenance structure, comprises the access structure be made up of Steel Structure, it is characterized in that, at the one-sided installation hound of Steel Structure, and on the steel pipe of Steel Structure, increase leg box and hound carry out fastener and be connected and fixed.
Further, the upper end of hound is provided with joint, and joint is connected with the angle box be welded on Steel Structure by bolt; The afterbody welding gusset plate of hound, gusset plate is also welded on angle box on Steel Structure by bolt and another and is fixed and is connected.
The present invention by replacing original steel-tube construction in the hound structure of Steel Structure one-sided use belt lacing and gusset plate, and carries out fastener be connected and fixed by increasing leg box structure and hound on steel pipe, thus achieves detouchable access function.The airworthiness that this invention structure is simple, good reliability, easy-to-operate characteristic can improve aircraft further, has low cost of manufacture, feasibility advantages of higher.

Fig. 2 is I face partial schematic diagram.
Fig. 3 is that A is to schematic diagram.
Fig. 4 is II partial schematic diagram.
Fig. 5 is that B is to schematic diagram.
1. Steel Structure fuel tank area, 2. hound, 3. Steel Structure in figure, 4. angle box (I), 5. bolt (I), 6. top connection, 7. bolt (II), 8. angle box (II), 9. bolt (III), 10. gusset plate.
Detailed description of the invention
The present invention is illustrated further below in conjunction with accompanying drawing.
As shown in Figure 1, fuel tank installation and maintenance structure of the present invention refers to the access structure be made up of Steel Structure, realizes access function by substituting original steel-tube construction with detouchable hound 2 in Steel Structure fuel tank area 1.
Fig. 2 with Fig. 3 is then shown hound 2 upper part and is connected mutually by the angle box (I) 4 be welded on Steel Structure 3.Wherein hound 2 top increases top connection 6 structure by the method for welding and bolt (I) 5, and joint 6 is connected with angle box (I) 4 by bolt (II) 7 again simultaneously.Fig. 4 and Fig. 5 display be that the afterbody of hound 2 is increased welding gusset plate 10 structure and to be fixed with angle box (II) 8 by bolt (III) 9 and is connected, be welded on Steel Structure 3 with (II) 8, hour angle box, thus achieve the connection of Steel Structure 3 and hound 2 lower part.
In the installation and maintenance process of fuel tank, only need bolt (II) 7 and bolt (III) 9 to turn on and remove hound and can create path.
Claims (2)
1. a new-type fuel tank installation and maintenance structure, comprises the access structure be made up of Steel Structure, it is characterized in that, at the one-sided installation hound of Steel Structure, and on the steel pipe of Steel Structure, increases leg box and hound carry out fastener and be connected and fixed.
2. new-type fuel tank installation and maintenance structure according to claim 1, it is characterized in that, the upper end of hound is provided with joint, and joint is connected with the angle box be welded on Steel Structure by bolt; The afterbody welding gusset plate of hound, gusset plate is also welded on angle box on Steel Structure by bolt and another and is fixed and is connected.
