Description
Technical field
Patent of the present invention relates to a kind of industrial field and uses pipeline inner machine people, especially relates to a kind of Track-wheel type pipeline cleaning robot adapting to different tube diameters change.
Background technique
Pipeline is as power station pipeline, oil transport pipeline, the gas pipeline such as rock gas, coal gas, defeated, drainage pipe, Central Air Conditioner Used in Buildings pipeline etc., through prolonged application, inner-walls of duct is smooth and regular shape as the new pipeline laid no longer, there will be the adhesion of fouling in various degree and impurity, thus cause the uneven of inner-walls of duct.As aqueduct inwall can produce the various informative sludge such as incrustation scale, rust staining, oil transport pipeline occurs that internal diameter blocks, so greatly increase the resistance in fluid delivery process, the conveying capacity of pipeline is greatly reduced, but also corrosion and injury can be caused to pipeline material, can pipeline breaking be made time serious, cause leaking of transporting fluid, the dangerous situation even burst.Therefore economically consider with security standpoint, need research and development pipeline robot to solve above situation.
Pipeline robot is as crawling equipment in the pipe of a kind of high intelligence, high automation because needs progressively grow up, and this novel equipment plays a part to deliver various working tool in pipeline operations.Pipeline robot is a kind of mechanical device can walked along pipeline internal, can enter in non-structural pipeline environment less than people, complicated and changeable, by carrying one or more sensors and operation equipment as ultrasonic sensor, vortex sensor, pipe cleaning device, pipeline crack and pipe joint soldering installation, anti-corrosion spray device etc., complete the operations such as pipe detection, cleaning and welding under remote control, to ensure pipe safety and unblocked to work.The pipeline inner machine people that current industrial field uses is varied, is broadly divided into: pipeline cleaning robot, detecting robot of pipe and joint coating on pipeline robot by function difference.
Major part pipeline robot can only at the conduit running of specific caliber, and actual conditions to be pipeline robot need the caliber of creeping not to be single constant.Such as, first time needs the pipeline of cleaning to be 400mm, and the pipeline of second time cleaning is 500mm or 600mm.Pipeline due to Long-Time Service there will be concavo-convex, therefore need shrink in the pipeline of different calibers and open traveller, pipeline robot can be walked in different calibers, can pass through smoothly when running into obstacle.For making in-pipe robot for steady in pipe, start and stop reliably, walking, traveller needs to be pressed on tube wall with suitable positive pressure, for creeping of pipeline robot provides enough frictional force; When caliber changes, the impacting force between traveller and tube wall keeps stable.For realizing the function adapting to caliber change, main employing spring closed force mechanism, when caliber excursion is larger, easily lose the characteristic of normal seal force, the tractive force of pipeline robot will be no longer stable, and the functional reliability of robot will be very restricted; Substantially or experimental prototype, load is low, and obstacle climbing ability is poor for the pipeline robot developed at present, can only be engaged in pipeline dedusting, single homework that detection even load ability is lower.
More to the research of pipeline cleaning robot at present, if application number is the Chinese utility model patent of CN201320854277.1, the day for announcing is 2014-07-30, describes a kind of by main frame
,the composite crawler pipeline robot device of adsorbing mechanism and conduit composition, main frame drives the composite crawler mechanism of both sides by transmission shaft, adsorbing mechanism simultaneously on main frame is communicated with catheter interface, ensure that it is adsorbed in tube wall, without the need to producing negative pressure by sucker, by means of only the magnetic force of strong magnets on crawler belt, operation of advancing can be realized.But this robot can not adapt to caliber change, load capacity and obstacle climbing ability are not strong, can not effectively adsorb for vertical or that angle of inclination is larger nonmagnetic substance.For another example application number is the Chinese invention patent of CN105135151A, the day for announcing is 2015-12-09, describe a kind of by screw mechanism, slider-rocker mechanism, the crawler belt type pipeline robot with Initial adaption and adaptation function of parallel-crank mechanism composition, can the different pipe diameter of Initial adaption change and keep between crawler belt and inner-walls of duct, there is certain pressure, can pass over the rough local disturbance of pipe surface, but this robot profile is long, traveling-capability in elbow is poor, and employing slider-rocker mechanism, parallel-crank mechanism realizes adapting to caliber change, mechanism is in course of adjustment and easily occurs movement dead, i.e. stuck phenomenon, more difficult in the duct, and the load capacity of robot is not strong, more detection or washing unit etc. cannot be carried.
