Technical field
The present invention relates to a kind of truss-like telescopics to arrest metamorphic mechanisms.
Background technique
Space manipulator has integrated spatial perception, motor-driven and operational capacity, passes through in-orbit operation, ground remote operating Or autonomous operation mode complete spacecraft in-orbit assembly, pollution cleaning, observation with check, malfunctioning module replacement, it is in-orbit filling, The work such as consumable load replacement and supplement, track cleaning, Orbit Transformation, are the Core equipments of the in-orbit installation and maintenance of spacecraft.
Chinese patent literature CN107685881A discloses a kind of spatial flexible acquisition equipment and its catching method, this is caught Obtain device by for recycling tether, winding target object get rid of rope, two get rid of bar and rack forms.It has only with two Have the portion of pasting gets rid of the capture task restricted and can be completed to target.The operating distance of the device is remote, and applicable object is relatively broad, and It is lower to the requirement of control system in capture-process.
Chinese patent literature CN106584507A discloses a kind of Grazing condition pneumatic machinery arm configuration, and structure is in lengthwise Cone.The mechanical arm is mainly by Grazing condition machinery arm body, robot central body and evenly around robot central body axis pair Claim the air flue composition of distribution.Wherein, air flue extends and from the big one end of diameter to the small one end of diameter apart from end face certain distance To maintain the gas in air flue, one layer of fibre reinforced composites are arranged in mechanical arm outer surface.Flexible mechanical arm body uses Elastic material has very strong deformability.The device is suitable for arresting the object of complicated shape.
Chinese patent literature CN106584507A discloses a kind of clipping inflation catching hand, and there are two symmetrical machines for tool Tool arm.The mechanical arm can complete holding action inwardly and outward expansion action.To complete both movements, in mechanical arm Front end the inflation valve for spreading arm of one arc is housed, be provided with longitudinal wind spring on the outside of extending arm, outer surface with it is right The extending arm bonding answered.The capture hand can capture space large scale noncooperative target.
Above-mentioned prior art is all made of flexible piece as mechanism body, therefore mechanism overall stiffness is poor, is not suitable for Object in space in capture movement.In addition, the size of arresting agency can be limited to using flexible piece, to limit capture The range of object.
Accordingly, it is desirable to provide a kind of truss-like telescopic arrests metamorphic mechanisms, telescopic arresting agency entirety is being improved Under the premise of rigidity, integrally-built weight is reduced, in conjunction with born of the same parents' principle is become, allows mechanism that change in size occurs, to expand The range of capture target.
Summary of the invention
In view of the drawbacks of the prior art, the present invention provides a kind of truss-like telescopics to arrest metamorphic mechanisms, using truss Formula structure, overall weight is light, advantageously reduces delivery cost;Using born of the same parents' structure is become, the occupied space of overall structure is reduced.
To achieve the goals above, the present invention provides a kind of truss-like telescopics to arrest metamorphic mechanisms, wherein including more A identical change born of the same parents' unit, becoming born of the same parents' unit includes:
