Description
Technical field
The utility model belongs to aircraft door design field, and in particular to it is a kind of with idler wheel course limit hatch door lead
To device.
Background technique
For blocking or half blocking type hatch door, when fuselage is in bending or torsion, fuselage doorframe can have moderate finite deformation, cabin
Door is suspended on fuselage frame or beam, and hatch door and fuselage have biggish relative deformation in course direction at this time.If do not limit hatch door with
The course relative deformation of fuselage, there will be cabin door structures or mechanism and airframe structure to generate unfavorable interference.Therefore, it is necessary to design
The course displacement of special structure limitation hatch door, in addition this can increase construction weight.
Summary of the invention
The purpose of this utility model is: a kind of hatch door guiding device with the limit of idler wheel course is designed, to solve current cabin
The technical issues of course relative deformation of door and fuselage.
To solve this technical problem, the technical solution of the utility model is:
It is a kind of with idler wheel course limit hatch door guiding device, the hatch door guiding device include: guiding wheeling support 1,
Directive wheel 2, course displacement limitation wheel 3, guide groove 4；The guiding wheeling support 1 is mounted on hatch door；The directive wheel 2 connects
It connects on guiding wheeling support 1；The course displacement limitation wheel 3 is connected on guiding wheeling support 1；The guide groove 4 is installed
On fuselage doorframe, the design of guide groove 4 has platform 5, in hatch door closed state, at the platform 5 and course displacement limitation wheel 3
In course relative position.
The course displacement limitation wheel 3 and the course distance of the platform 5 is less than hatch door other structures and fuselage knot
The distance of structure.
In the maximum vertical and maximum laterally opposed deformation of fuselage and hatch door, the course displacement limitation wheel 3
Kernel of section position 6 must not exceed 5 boundary of platform, i.e., the length that platform 5 is contacted with the line that course is displaced limitation wheel 3 is not less than boat
The half of 3 height of wheel is limited to displacement.
The course displacement limitation wheel 3 is matched with the platform 5, under hatch door closed state, fuselage and hatch door
Play the role of limiting the displacement of hatch door course when generating course relative deformation.
The connection type of the directive wheel 2 and guiding wheeling support 1 is to be bolted.
The course displacement limitation wheel 3 and the connection type of guiding wheeling support 1 is to be bolted.
The beneficial effects of the utility model are: the hatch door guiding device structure letter with the limit of idler wheel course of the utility model
Single, design is implemented simply, using existing hatch door guiding device, increases a small amount of structure design, it can be achieved that the displacement of limitation hatch door course
Effect；Need not design specialized structure, to mitigate construction weight.

Fig. 3 is guide groove structure figure；
Fig. 4 is course displacement limitation wheel and position of platform relational graph；
Wherein, 1: guiding wheeling support；2: directive wheel；3: course displacement limitation wheel；4: guide groove；5: platform；6: course position
Move the kernel of section position of limitation wheel, L is contact line length, H is course displacement limitation wheel height.
Specific embodiment
The hatch door guiding device with the limit of idler wheel course of the utility model is described in detail with reference to the accompanying drawing.
As shown in Figure 1, the hatch door guiding device with the limit of idler wheel course of the utility model, comprising: guiding wheeling support 1,
Directive wheel 2, course displacement limitation wheel 3, guide groove 4；The guiding wheeling support 1 is mounted on hatch door；The directive wheel 2 is logical
It crosses and is bolted on guiding wheeling support 1；The course displacement limitation wheel 3 is bolted on guiding wheeling support 1；Institute
The guide groove 4 stated is mounted on fuselage doorframe, and the design of guide groove 4 has platform 5, in hatch door closed state, the platform 5 and boat
Course relative position is in displacement limitation wheel 3.The structure chart of wheeling support 1 is wherein oriented to as shown in Fig. 2, 4 structure of guide groove is shown
It is intended to as shown in Figure 3.
The course displacement limitation wheel 3 and the course distance of the platform 5 is less than hatch door other structures and fuselage knot
The distance of structure.
In the maximum vertical and maximum laterally opposed deformation of fuselage and hatch door, the course displacement limitation wheel 3
Kernel of section position 6 must not exceed 5 boundary of platform, i.e., the long L degree that platform 5 is contacted with the line that course is displaced limitation wheel 3 is not less than
The half of 3 height H of course displacement limitation wheel, as shown in Figure 4.
Directive wheel 2 and guide groove 4 cooperate, and hatch door correctly fastens with a bolt and undertakes hatch door gravity and vertical after locking in flight course
Downward overload and course overload.Play the role of controlling hatch door motion profile in hatch door lifting process.Course displacement limit
Platform 5 on ratch 3 and guide groove 4 cooperates, and under hatch door closed state, fuselage plays when generating course relative deformation with hatch door
Limit the effect of hatch door course displacement.
