Description

A kind of novel full driving composite adsorption climbing robot
Technical field
The invention belongs to the specialized robot technical field, is a kind of novel full driving composite adsorption climbing robot specifically.
Background technology
Magnetic adsorption wall climbing robot is a kind of of specialized robot, be that design is used under severe, danger, limiting case, carries out a kind of automated machine device of operations specific as welding, polishing, inspection, detection etc. on the magnetic conduction wall, and more and more be subject to people's attention.Magnetic adsorption wall climbing robot is widely used in the production and construction of the ferromagnetic structures such as nuke industry, petrochemical industry, building industry, fire department, ship building industry at present.
Climbing robot must have two basic function: wall adsorption function and locomotive function.But, the two is again contradiction: the load-carrying capacity of robot is stronger, require the adsorption affinity between climbing robot and magnetic conduction wall larger, but this has also caused the resistance of climbing robot when motion larger, the adsorption power of climbing robot and travelling performance are contradiction.
Existing magnetic adsorption wall climbing robot mainly contains magnetic foot formula climbing robot, magnetic wheel type climbing robot, crawler type magnetic adsorption wall climbing robot, gap adsorbed wall-climbing robot.
Magnetic foot formula climbing robot is that the adsorption affinity provided by the magnetic foot is adsorbed on wall, because its walking characteristics have determined that its adsorption affinity is necessary adjustable, adopts electromagnet that adsorption affinity is provided, as eight sufficient magnetic adsorption wall climbing robots of HIT's development more.But magnetic foot formula climbing robot footwork is controlled more complicated, kinematic dexterity is bad; In addition, adopt electromagnet that adsorption affinity is provided, not only need to consume electric energy, the potential safety hazard that also exists accident power-off to cause.
The magnetic wheel type climbing robot is to lean on the adsorption affinity of magnet-wheel to be adsorbed on the magnetic conduction wall.The applying date is on January 5th, 2004, " magnetic roller adsorption type wall climbing robot " that the patent documentation that application number is 200410016429.6 relates to, its technical scheme is: comprise the revolver structure, bearing support, detection architecture, roller, code-disc, the location correction structure, right wheel construction, the revolver structure is identical with right wheel construction, symmetry is fixed on the both sides of bearing support, detection architecture is fixed on the front of bearing support, roller and code-disc are fixed on the centre of bearing support, the location correction structure is connected to the bearing support rightmost side, it can adapt to the curvature of wall, do the rotation of certain angle around bearing support, proofread and correct the pose of robot in robot motion's process.The present invention can complete the weld seam detection in the hazardous environments such as oil barrel.The characteristics of foregoing invention are that kinematic dexterity is better, but, because effective adsorption area of magnet-wheel is little, the magnetic energy utilization rate is not high, and load-carrying capacity is poor.
The crawler type magnetic adsorption wall climbing robot is that the suction block by being arranged in crawler-type mobile mechanism is adsorbed on the magnetic conduction wall.The applying date is " the crawler-type permanent magnet wall climbing mechanism " that patent documentation that January 26, application number in 2000 are 00200795.9 relates to, its main technical schemes is: this climbing mechanism is by car body, power pack section and traveling gear three parts form, car body is a box-shaped flexible structure, power pack section is installed in inside, power pack section is two electrical motors and speed reduction gearing thereof, and its output shaft is respectively with the drive sprocket of motor vehicles bodies both sides.Traveling gear is placed in the car body both sides, by drive sprocket, and guide wheel, permanent magnet and chain tensioning mechanism form, and each drive sprocket drives three closed chains, and two gap locations between three chains look to bear a heavy burden being evenly arranged permanent magnet along the chain total length.Be characterized in that load-carrying capacity is strong, but its kinematic dexterity is poor, particularly, when carrying out divertical motion, because area of contact between crawler belt and magnetic conduction wall is large, cornering resistance is large, and Turning radius is large, and steering flexibility is poor.
The gap adsorbed wall-climbing robot be by be arranged on chassis and the magnetic conduction wall between there is certain interval permanent magnet be adsorbed on the magnetic conduction wall.The applying date is " the wheeled non-contact magnetically adsorption wall climbing robot " that patent documentation that October 8, application number in 2005 are 200510086383.X relates to, its technical scheme is: comprise wheel type mobile mechanism and permanent magnetic adhesion device, wheel type mobile mechanism comprises chassis, is arranged on the driver train on chassis, the drive wheel driven by driver train.Described drive wheel is arranged symmetrically with, and adopts differential type of drive, relies on the differential of drive wheel to realize turning on the magnetic conduction wall; Permanent magnetic adhesion device is arranged on described chassis, between described permanent magnetic adhesion device and magnetic conduction wall, is non-contacting, and the magnetic energy utilization rate is high, high adsorption capacity.Above-mentioned patent characteristics are that adsorption affinity is large, but, because all drive wheels are all the cylinder wheels that car body turns to relatively, cornering resistance is large, and steering flexibility is poor.
In sum, better and load-carrying capacity is poor, or load-carrying capacity is strong and kinematic dexterity is poor, fails to solve preferably the contradiction that climbing robot moves and adsorbs for existing climbing robot or kinematic dexterity, and Combination property is bad.
Summary of the invention
The objective of the invention is for overcoming the deficiency of prior art in Combination property aspect kinematic dexterity and load-carrying capacity two, solve climbing robot absorption and mobile contradiction, design a kind of full driving composite adsorption climbing robot, make its can be on wall when thering is strong load-carrying capacity flexible motion, Combination property is better, thereby solves problems of the prior art.
