Background technique
In recent years, unmanned plane application field is more and more wider, and more and more present age high-quality precision and sophisticated technologies are put into wherein, and most often The purposes seen be investigate, take photo by plane, surveying and drawing, movies-making.It is not difficult to find out that the main application of current unmanned plane, removes certain dedicated Military unmanned plane is largely used to entertain, and does not develop the potential of unmanned plane in domestic life completely.We more feel By the importance of intelligence transport, and the transport on ground is frequently subjected to the limitation of landform.Have currently on the market on a small quantity Grabbing device based on sucker, but they expose that crawl is unstable, and cargo is easy to ask from what is fallen in the air in practical Topic, this not only can cause to damage to cargo, but will constitute a threat to the personnel safety carried on the way.Therefore, a can be secured The unmanned plane mechanical arm for grabbing cargo, can preferably cater to communication and transport market instantly.
Summary of the invention
The object of the present invention is to provide a kind of mechanical arms for being equipped on unmanned plane, not only can be complete as sucker It at simple handling work, and solves the problems, such as that sucker crawl is unstable, carries out cargo transport with the mode of machinery crawl, More secure and reliable is conducive to adapt to more complicated handling situations.
The present invention adopts the following technical scheme that realize:
A kind of mechanical arm being equipped on unmanned plane, including the control of pedestal, four-bar mechanism, distance rod steering engine, intermediate plate, intermediate plate Steering engine, carbon beam, fixed control steering engine and L-type fixinig plate;Wherein,
Four-bar mechanism is at least a pair of, and each pair of four-bar mechanism is symmetrical arranged, two stocks of each four-bar mechanism Respectively it is symmetricly set on two the first distance rods and two connecting rods of two sides of base, two the first distance rods and two connecting rods One end and pedestal it is hinged, distance rod steering engine be arranged on the base, pass through driving the first distance rod rotation drive four-bar mechanism It opens or is closed, the other end of two connecting rods is hinged with corresponding intermediate plate respectively, and the other end of two the first distance rods is opened Equipped with sliding slot, two the first distance rods by pass through sliding slot carbon beam with and two connecting rods it is hinged intermediate plate top be connected, intermediate plate The other end of first distance rod is arranged in control steering engine, is connected by link mechanism, the second distance rod with carbon beam, structure At slider-crank mechanism;
The intermediate plate bottom being connected with each four-bar mechanism and one end of L-type fixinig plate are hinged, the other end of L-type fixinig plate For free end, fixed control steering engine is arranged on intermediate plate, for driving L-type fixinig plate to rotate.
A further improvement of the present invention lies in that pedestal includes installation frame pedestal and is mounted on installation frame base bottom Distance rod steering engine mounting base, one end of two stocks of four-bar mechanism and distance rod steering engine mounting base are hinged, and distance rod rudder Machine is arranged in distance rod steering engine mounting base.
A further improvement of the present invention lies in that further including stirring control steering engine and small-sized plectrum, small-sized plectrum setting is being pressed from both sides The inside of piece and L type fixinig plate hinged place is stirred on control steering engine setting intermediate plate, for driving small-sized plectrum to rotate.
A further improvement of the present invention lies in that the intermediate plate being connected with each four-bar mechanism at least there are two, when multiple lead to Carbon beam is crossed to be sequentially connected in series together.
A further improvement of the present invention lies in that being also provided with spare mounting hole on intermediate plate, steering engine is controlled for changing fixed Position adapt to the crawls of different scale articles.
A further improvement of the present invention lies in that each intermediate plate is provided with small-sized protrusion on the inside of bottom end, it is used for Increase the stress with transport cargo.
A further improvement of the present invention lies in that in use, connecting electricity after determining that mechanical arm is correctly installed on uav bottom Source starts unmanned plane;Above unmanned plane during flying to target item, the rotation of distance rod steering engine drives the first distance rod to centre Lower rotation, after the first distance rod of two sides rotates predetermined angle, the intermediate plate of end controls steering engine rotational angle, pushes double leval jib Intermediate plate head carbon beam is pushed into long through-hole front end by mechanism kinematic, thus make intermediate plate formed internal buckle shape, increase intermediate plate end with The stress of target item consolidates clamping working condition to increase friction;After unmanned plane rises preset height, outside intermediate plate end The fixed control steering engine rotational angle in end, makes the same internal buckle of L-type fixinig plate, guarantees that target item will not slide in the air;So far, should Mechanical arm completes the movement of crawl target item;
After unmanned plane during flying launches place to article, it is drop to preset height, the fixed control steering engine in outside intermediate plate end turns Dynamic angle unclamps L-type fixinig plate, and the second distance rod end intermediate plate controls steering engine and drives slider-crank mechanism movement, by intermediate plate head Portion's carbon beam retracts long through-hole first section, and intermediate plate is made to enter state of organizing work, and in-board clip end steering engine occurs corresponding rotation, dials Dynamic plectrum carries out push movement to transport article, it is ensured that article is correctly launched, and is prevented article from hook occurs with mechanical arm and is pulled;Most Afterwards, distance rod steering engine rotates, and the first distance rod is lifted, and stretched condition is presented in entire mechanical arm, does for crawl work next time Prepare;So far, which completes to launch the movement of target item.
The present invention has following beneficial technical effect:
A kind of mechanical arm being equipped on unmanned plane provided by the invention, the mechanical arm generate torque band by distance rod steering engine Dynamic the first distance rod of two sides is drawn close to centre, after two sides distance rod rotates predetermined angle, the intermediate plate control steering engine rotation of end Angle, throw crank slide block mechanism movement, is pushed into long through-hole front end for intermediate plate head carbon beam, so that it is interior buckle-shaped to form intermediate plate Shape increases the small-sized protrusion in intermediate plate end and transports the stress of cargo, increases friction, and herein according to self-locking formula: tan β =f (static friction factor), there are locking phenomenons, are conducive to firm clamping working condition.The fixed control steering engine in outside intermediate plate end turns Dynamic angle, makes the same internal buckle of L-type fixinig plate, and target item carrying is avoided to slide on the way.When needing to place article, outside Control flaps prow elder generation rotational angle is fixed in intermediate plate end, unclamps L-type fixinig plate, and distance rod end intermediate plate controls steering engine and drives song The movement of handle slide block mechanism, retracts long through-hole first section for intermediate plate head carbon beam, intermediate plate is made to enter opening working condition.Further, interior Side intermediate plate end stirs control steering engine and rotates, and stirs small-sized plectrum and carries out push movement to transport article.Distance rod steering engine Rotation, the first distance rod is lifted, and extended state is presented in entire mechanical arm.
The present invention is different from previous sucker crawl structure, makes to grab by the way of machinery crawl firm effective and sharp Guarantee article correct placement with four-bar mechanism.
