Description
Technical field
This utility model belongs to depopulated helicopter field, particularly to a kind of adaptive belt clamping device.
Background technology
Rotor wing unmanned aerial vehicle, also referred to as depopulated helicopter, its construction is fairly simple, and also ratio is less expensive for price, even more important
It is that it does not need emission system moreover it is possible to VTOL, more can freely hover, and motility of flying is quite superb,
Can use various speed, flown with the air route of various flight profile, mission profiles.In general flight quality, also can present that " two is little
The important feature of one height "：Chatter is little, noise is little, and Reliability comparotive is high.Therefore, in the country that Helicopter Technology is flourishing, nobody drives
Sail helicopter to begin to very early develop.For example, the Kaman company of the U.S. just once released pilotless helicopter early in the fifties, and
And had some models to put into the practice stage.
Unmanned helicopter generally uses power belt transmission power, and existing unmanned plane power belt is all not provided with belt
Hold down gag, and the power of depopulated helicopter power belt transmission is not a steady state value（As when starting and when accelerating flight）,
Its power is change, therefore when power changes, power belt can produce shake, and this shake is unfavorable for flying of unmanned helicopter
Row is stable, brings hidden danger to flight safety.
Content of the invention
For overcoming the problem of the deficiencies in the prior art and presence, this utility model provides a kind of adaptive belt compression dress
Put, can automatic impaction power belt, it is to avoid shake in power belt, ensure the flight safety of depopulated helicopter.
This utility model is achieved through the following technical solutions：
A kind of adaptive belt clamping device, including the support body being fixed on body lateral shelf plate, support body is hinged with work
Lever, motion bar and support body arrangement at an acute angle, the middle part of motion bar is hinged with the elastic mechanism being installed on support body, motion bar
Free end is provided with the contact roller being butted on power belt.
Described elastic mechanism includes expansion link and fixed cylinder, and expansion link is cased with spring, and spring is located in fixed cylinder, stretches
Bar is hinged with motion bar, and it is hinged with support body that fixed cylinder passes through bracing frame.
Support frame as described above includes the support bar of four square corner arrangements, and one end of four support bars is both secured to frame
On body, the other end is provided with the support block of " returning " shape, and support block is provided with rotating shaft, and rotating shaft is connected with fixed cylinder.
It is hinged with support body that described motion bar passes through regulating block.
Described regulating block is provided with jointed shaft, and motion bar is connected with jointed shaft, and support body is provided with strip installing hole, adjusts
Block is fixed by strip installing hole and support body.
Described contact roller is column, is made by aluminium alloy.
Described support body and regulating block are made by aluminium alloy.
The contact roller of this utility model setting is butted on power belt, and motion bar is connected with elastic mechanism, works as power belt
When the power of transmission changes, elastic mechanism promotes motion bar activity so that contact roller compresses power belt according to change, it is to avoid
Shake in power belt, ensures the flight safety of depopulated helicopter.

Specific embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with the drawings and specific embodiments this utility model is made into
One step describes in detail.
As shown in Figure 1, Figure 2 and Figure 3, a kind of adaptive belt clamping device, including being fixed on body lateral shelf plate 1
Support body 3, support body 3 is made by aluminium alloy.Motion bar 4, motion bar 4 and support body 3 arrangement at an acute angle are hinged with support body 3.Live
The middle part of lever 4 is hinged with the elastic mechanism 5 being installed on support body 3, and elastic mechanism 5 can promote motion bar 4 to rotate around hinged place.
The free end of motion bar 4 is provided with the contact roller 6 being butted on power belt 2, and contact roller 6 is column, is made by aluminium alloy.
Elastic mechanism 5 includes expansion link 51 and fixed cylinder 52, and expansion link 51 is cased with spring 53, and spring 53 is located at fixed cylinder
In 52, expansion link 51 is hinged with motion bar 4, and it is hinged with support body 3 that fixed cylinder 52 passes through bracing frame 7.It is just in that bracing frame 7 includes four
The support bar 71 of square corner arrangement, one end of four support bars 71 is both secured on support body 3, and the other end is provided with " returning " shape
Support block 72, support block 72 is provided with rotating shaft 73, and rotating shaft 73 is connected with fixed cylinder 52.
Motion bar 4 is hinged with support body 3 by regulating block 8, and regulating block 8 is made by aluminium alloy.Regulating block 8 is provided with hinge
Spindle 81, motion bar 4 is connected with jointed shaft 81, and support body 3 is provided with strip installing hole 31, and regulating block 8 is installed by strip
Hole 31 is fixing with support body 3.By adjusting the installation site of regulating block 8, the angle between adjustable bar 4 and support body 3.
The work process of the present embodiment：When the power of depopulated helicopter becomes big suddenly, the power of power belt 2 transmission is unexpected
Become big, because a layback of power belt 2 obtains tighter, power belt 2 opposite side occurs lax, and now, spring 53 promotes flexible
Bar 51 stretches out, thus promoting motion bar 4, the contact roller 6 on motion bar 4 pushes against power belt 2, prevents power belt 2 from occurring trembling
Dynamic, ensure the flight safety of depopulated helicopter.
Above-described embodiment is preferably implementation of the present utility model, is not to restriction of the present utility model, not
On the premise of departing from inventive concept of the present utility model, any obvious replace all protection domain of the present utility model it
Interior.
