Robot of the present invention mainly is theory and the thought of having used a kind of " motor-worm and gear-Drive and Control Circuit-display circuit ".The energy that utilizes power supply to produce drives revolution, the main shaft of robot is rotated and the work of bite strap driving wheel formula system by gear by motor, and the control by control circuit, thereby reaches the purpose that dolly advances, retreats.Real-time image information is transferred on the receiving screen for the staff by data collecting card after by camera collection and observes.Wherein, the concrete working principle of moving structure is as follows:
In the two groups of supports in the front and back of mobile mechanism, three big driving wheels all are radially equally distributed, and front and back two-part all are symmetrical vertically, and therefore totally six of the strong points satisfy the shape sealing condition.When mobile mechanism walked, three driving wheels were radially evenly distribution, determine planes at 3,3 all the time on a cylndrical surface, therefore can realize self contering, under the effect of support device, driving wheel tightly is pressed on the inner-walls of duct, has stronger adaptability.Because two groups of each six uniform driving wheels, each worm screw of front and back that links with motor must drive three worm gears simultaneously so, because reaching driving wheel and these driving wheels by worm gear must can be around the worm gear center steering, owing to three worm gears whiles and a worm meshing transmission in parallel, novel structure, transmission efficiency are also high.At last, driven by motor worm screw, worm gear motion, the frictional force that wheel produces by the positive pressure that acts on inner-walls of duct makes robot mobile forward or backward along the inner-walls of duct straight line, becomes the main drive system of pipeline robot.
In conjunction with Fig. 1, Fig. 3, wherein K switch 1, K2 control advancing of robot, and K3, K4 control robot retreats, and they and 12V power supply have constituted the Drive and Control Circuit system of robot, for robot provides electric power.
And motor 1, wheel support 2 and follower 3 have constituted electric system, wherein the rotation of motor 1 provides power for advancing of robot, be the necessary condition of worm and gear system works, 3 followers of playing a supporting role 3 have been installed on the support 2, make that the walking of robot is more stable.
In conjunction with Fig. 2, the main body of described worm and gear system is made of worm gear 4 and worm screw 5, worm gear 4 and worm screw 5 tight interlocks, and the rotation that drives worm screw 5 by motor 1 makes worm gear 4 also rotate thereupon.The mobile mechanism of robot all is radially equally distributed by 6, three big driving wheels 6 of driving wheel, and front and back two-part all are symmetrical vertically, and therefore totally six of the strong points satisfy the shape sealing condition.When robot ambulation, three driving wheels 6 are radially evenly distribution, determine planes at 3,3 all the time on a cylndrical surface, therefore can realize self contering, under the effect of support device, driving wheel 6 tightly is pressed on the inner-walls of duct, has strengthened the stability of robot.Because two groups of each six uniform driving wheels 6, then each worm screw 5 of front and back that links with motor 1 must drive three worm gears 4 simultaneously, because reaching driving wheel 6 and these driving wheels 6 by worm gear 4 must can be around worm gear 4 center steering, because three worm gears 4 mesh transmission in parallel with a worm screw 5 simultaneously, novel structure, transmission efficiency are also high.At last, motor 1 drives worm screw 5, worm gear 4 motions, and the frictional force that driving wheel 6 produces by the positive pressure that acts on inner-walls of duct makes robot mobile forward or backward along the inner-walls of duct straight line, becomes the main drive system of pipeline robot.And but driving wheel 6, reducing bar 7, connecting rod 8 and bearing pin 10 have constituted the wheeled system of reducing, but there are 3 groups of totally 12 reducing bars in the wheeled system of reducing.When surveying the pipeline of different tube diameters, along with the variation of caliber, reducing bar 7 rotates, thereby turns over same angle along worm gear 4 around below bearing pin 10 by the driving wheel 6 that links to each other with top bearing pin 10, finally realizes the process of wheeled system reducing.When the reducing scope of the wheeled system of reducing reached maximum reducing, the reducing bar 7 of robot was vertical fully with the direction of advance of robot.
Offset direction, compression degree when but connecting rod 8 has guaranteed the wheeled system works of reducing are all identical, have significantly reduced the probability that the robot mechanical system may break down.In addition, the metal shell 9 of robot has played protection robot body's effect, prevents that robot from coming to harm when proper functioning, has improved the survival rate of robot greatly, increases the working efficiency of robot.
In conjunction with Fig. 4, vehicle-mounted pick-up head 11 and power supply 12 have constituted data real-time collecting system, are responsible for collecting the image that robot is seen.Data collecting card 13 is responsible for the data transfer that collects is become the form of video, and 14 of receiving screens are display platforms, with real-time image output, to make things convenient for the timely situation in staff's observation tube.This part is the display circuit system of robot.
In conjunction with Fig. 1, Fig. 2, Fig. 3, these three parts (electric system, worm and gear system and Drive and Control Circuit system) have constituted the Machinery Control System of robot, guarantee that robot can realize functions such as forward-reverse and reducing normally.
In conjunction with Fig. 4 (display circuit part), it is the image delivering system of robot, and the image information that it collects camera changes into numerical information and is presented on the receiving screen, observes for the staff.
As from the foregoing, robot of the present invention is of compact construction and is stable preferably.This robot is by two groups of wheeled system support, and front and back structural distribution compactness can realize self contering, has stronger stability.
