Description

A kind of spirally driven walking robot in pipe
Technical field
The present invention relates to a kind of robot of in pipeline, walking, that is to say that operations such as detection for various industrial delivery ducts, cleaning, reparation provide a kind of later-model pipe walking robot.
Background technology
The important carrier that pipeline is carried as oil, natural fuels, the isometric distance of tap water, effect in modern industry construction and daily life becomes increasingly conspicuous, for the consideration of working stability, safety and work efficiencys such as pipeline installation, maintenance and detection, pipeline operations requires to adopt pipe robot to replace manual operation as mobile vehicle more and more.The type of drive of pipe robot travel mechanism comprises motor-driven, Piezoelectric Driving, Electromagnetic Drive, air pressure driving, hydraulic-driven etc. both at home and abroad at present; And the walking manner of robot can be divided into inertia impact walking, climbing, elastic drive walking and running on wheels or the like, find by comparative study, existing pipe robot all exist such as: driving principle and complex structure, processing difficulties, inefficiency, then be difficult to weak points in various degree such as realizations, to such an extent as to they are very difficultly applied widely for the less pipeline of diameter.Application number [200710050056.8] discloses a kind of round pipe robot of screw drives, adopted the easier screw type of principle to drive and can reducing, but because driving wheel carrier and guiding wheel carrier are installed on two ends of body respectively, and body has certain length, therefore, be difficult to be applicable to the walking of curvature than large pipeline.
In sum, the development of pipe detection technology and practicability press for and create the more excellent pipe robot of performance.
Summary of the invention
The present invention seeks to overcome the shortcoming and defect of prior art, its technic relization scheme is: by Power Drive Unit, the guide piece and connect two-part universal-joint or ball pivot is formed of walking, Power Drive Unit is made of the motor-driven rotor, be separately installed with the wheel carrier that is symmetric arrangement more than two groups on the outer wall of rotor, two wheels are installed on every group of wheel carrier again, and the pivot center of the pivot center of wheel and rotor is an acute angle of inclination; Form and on the outer wall of walking guide piece by a cylindricality or cylindrical body the guiding wheel carrier that is symmetric arrangement more than two groups is installed, on every group of guiding wheel carrier two wheels are installed also, the pivot center of wheel is vertical mutually with the axis of cylindricality or cylindrical body; Epitrochanterian wheel carrier of Power Drive Unit and the guiding wheel carrier of walking on the guide piece are buoyancy body, and produce the inwall that all wheels that certain warp-wise harmomegathus amount makes wheel carrier and guiding wheel carrier are closely attached on pipeline all the time with elastic element.
The present invention compares with existing pipe robot, has following characteristics and advantage: 1). and simple in structure, the processing and manufacturing cost is low, and the warp-wise size can be as small as and is used in the pipeline that diameter is 40mm; 2). because use universal-joint or ball pivot are connected between Power Drive Unit and the walking guide piece, robot can be advanced in the bigger bend pipe of curvature flexibly and comfortably; 3). elastic elements such as employing spring make all wheels be close to inner-walls of duct, this robot can be advanced in the vicissitudinous pipeline of radius, play the shock-absorbing effect simultaneously, make that operation is more steady, and be not also can advance smoothly in the strict circular pipeline in vertical or cross section.
The invention will be further described below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is an integral structure scheme drawing of the present invention.
Fig. 2 is the front view and the right elevation of its Power Drive Unit.
Fig. 3 is the front view and the right elevation of its walking guide piece.
The specific embodiment
As embodiment, as shown in Figure 1, the present invention can and connect this two-part universal-joint 8 by Power Drive Unit, walking guide piece and form, Power Drive Unit (Fig. 2) drives round rotor 5 by motor 1 and constitutes, be separately installed with three groups of wheel carriers 2 that are symmetric arrangement on the outer wall of round rotor 5, two wheels 3 are installed on every group of wheel carrier 2 again, and the axis of the pivot center of wheel 3 and rotor 5 is an acute angle of inclination; Form and on the outer wall of walking guide piece (Fig. 3) by a cylinder or cylindrical body 11 three groups of guiding wheel carriers 12 that are symmetric arrangement are installed, on every group of guiding wheel carrier 12 two wheels 10 are installed also, the pivot center of wheel 10 is vertical mutually with the axis of cylinder or cylindrical body 11.Power Drive Unit can be a universal-joint 8 with the two-part connector of walking guide piece, also can be ball pivot, like this, robot can be turned in having than the bend pipe of larger radius of curvature neatly freely advance and retreat.Guiding wheel carrier 12 on wheel carrier 2 on the Power Drive Unit rotor 5 and the walking guide piece on cylinder or the cylindrical body 11 is buoyancy body, and produce the inwall that certain warp-wise harmomegathus amount makes all wheels 3 on the wheel carrier 2 and all wheels 10 on the guiding wheel carrier 12 be closely attached on pipeline all the time with spring 6 and spring 9 respectively, to adapt to certain limit interior conduit diameter variation.
The principle of work of this pipe walking robot is: motor 1 drives round rotor 5 and rotates, three groups of wheels 3 on round rotor 5 outer walls rotate because of the friction force that is closely attached on the inner-walls of duct generation, because of the pivot center of wheel 3 and the axis of rotor 5 are an acute angle of inclination, therefore, the path of motion of wheel 3 and inner-walls of duct contact point is the spatially spiral line along conduit axis, thereby forces Power Drive Unit to be walked along conduit axis; And three groups of guiding wheels 10 of the cylinder of walking guide piece or cylindrical body 11, because of its pivot center vertical mutually with the axis of cylinder or cylindrical body 11, so the walking guide piece can only advance with Power Drive Unit or retreats along the conduit axis direction, play directional tagging, in pipeline, can advance reposefully to guarantee robot integral body.The described motor 1 of this case both can adopt and carry battery-operatedly, also can adopt external AC or dc powered.
If install camera, cleanout tool or defect-detecting equipment 7 additional at motor 1 shell or end, and configuration radio control unit 4 (as shown in Figure 1), utilize means such as wireless video transmission imaging technique again, just can make this pipe robot finish the intellectuality of work such as pipeline installation, maintenance and detection.
