Description
Technical field
The present invention relates to a kind of undercarriages, and in particular to a kind of multi-point support take-off and landing device based on measurement unmanned plane.
Background technique
UAV referred to as " unmanned plane ", is manipulated using radio robot and the presetting apparatus provided for oneself
Not manned aircraft.Without cockpit on machine, but the equipment such as automatic pilot, presetting apparatus are installed.On ground, naval vessels or
Machine tool remote control station personnel track it, are positioned, are remotely controlled, telemetering and Digital Transmission by the equipment such as radar.It can be in radio
It takes off as conventional airplane under remote control or is launched with booster rocket, aerial launch can also be taken to by machine tool and flown.Recycling
When, the mode automatic Landing as conventional airplane landing mission can be used, can also be recycled by remote control parachute or block.It can
It is reused several times.It is widely used in aerial reconnaissance, monitoring, communication, antisubmarine, electronic interferences etc..Unmanned plane also has in fields of measurement
It widely applies, the place that can be difficult to reach or be inconvenient to operate to manpower measures.At present the undercarriage of unmanned plane be compared with
For common component, the dual strength on ground and unmanned plane is born during rising and falling, so the supportive for undercarriage is wanted
Ask higher, but existing its supporting point of unmanned plane undercarriage is less, is all rigid support, when by greater impact, is easy shape
Become and even fracture, unmanned plane is caused to crash.
Summary of the invention
The technical problem to be solved by the present invention is to existing unmanned plane undercarriages to use rigid support, and supporting point is less,
It when by greater impact, is easy deformation and even fractures, unmanned plane is caused to crash, its purpose is to provide one kind to be used based on measurement
The multi-point support take-off and landing device of unmanned plane, the structure of the undercarriage is simple, is adjusted according to the pressure being subject to when rising and falling, and realizes
Multi-point support fractures caused by preventing undercarriage from deforming to protect the safety of undercarriage.
The present invention is achieved through the following technical solutions：

Mounting rack connects and mounting rack can be rotated around junction, and guiding device is fixed with hydraulic cylinder outer wall and guiding device can
Hydraulic cylinder is pushed to rotate around its own axis.Hydraulic cylinder is inserted into installs case and under the promotion of guiding device around certainly
Body axis rotation, and hydraulic stem can stretch under hydraulic action, realize support when rising and falling, and impact force is subtracted
Slow, fluid pressure type structural support is big, can expand support range.
And guiding device includes guide pad, leading arm one and leading arm two, guide pad is arranged in installs case and can
It is moved in installs case, the top surface of installs case is provided with through slot, and leading arm one is fixed after passing through through slot with guide pad, leading arm one
The other end connect with leading arm two, and leading arm two can be rotated around with the junction of leading arm one, and leading arm two is separate
One end of leading arm one and the outer wall of hydraulic cylinder are fixed.When detection signal detection is to when the out-of-flatness of ground or the wheel of lifting/lowering support wheel
Face is not completely attached to ground, and power mechanism will push guide pad and move, so that leading arm one and leading arm two start movement and incite somebody to action
Hydraulic Cylinder slightly changes contact of the wheel face of lifting/lowering support wheel with ground in this way, out-of-flatness ground is avoided, until reaching setting
Contact demand is acted on by this fine tuning, is reduced since lifting/lowering support wheel does not reach pressure suddenly change when position causes to rise and fall, is caused
Undercarriage damage.
It also is recessed mounting groove in the bottom surface of mounting rack, the top of hydraulic stem is arranged in mounting groove, sets in mounting groove
It is equipped with connecting pin one, both ends are separately positioned in mounting rack after connecting pin one passes through hydraulic stem, and hydraulic stem can be around connection

Wall is recessed groove, and connector sleeve is arranged in groove, and connector sleeve is inserted into mounting groove, and connecting pin two is provided in mounting groove,
Both ends are separately positioned in mounting rack after connecting pin two passes through connector sleeve, and connector sleeve can be rotated around connecting pin two, connection
The lower section of connecting pin one and parallel with connecting pin one is arranged in pin two, connecting pin three is provided in groove, connecting pin three passes through
Both ends are separately positioned in fixing clamp after connector sleeve, and connector sleeve can be rotated around connecting pin three, and connecting pin three and connecting pin
Two is parallel.Using lifting/lowering support wheel by the impact with ground face contact so that mounting rack rotates, while the flexible of hydraulic stem slows down
These impact, by the rotation of hydraulic stem and the effect of connector sleeve, be maintained in reasonable deformation range, and rise and fall completion or
Person's pressure can timely return after being less than setting value.
Compared with prior art, the present invention having the following advantages and benefits：The structure of the undercarriage is simple, according to
The pressure being subject to when rising and falling is adjusted, and realizes multi-point support, to protect the safety of undercarriage, prevents undercarriage from deforming
Caused by fracture, solve existing unmanned plane undercarriage using rigid support, supporting point is less, when by greater impact,
It is easy the problem of deformation even fractures, unmanned plane is caused to crash.
