Description
Technical field
The present invention relates to a kind of portable pipe automatic ring to walking arrangement and pipeline processing method, belong to pipeline processing and technical field of construction.
Background technology
In processing and the job site of pipeline, often can run into pipe ring to the process requirements such as cutting, welding, anticorrosion with painting.For the not high situation of requirement on machining accuracy, can adopt manual type processing, this mode labour intensity is large, inefficiency.But the occasion of having relatively high expectations at some, this method is obviously to meet the requirements of.
Through existing pipe ring is found to the research of mechanism, in order to reach the demand of hoop processing, there were four kinds of automatic or automanual modes in the past:
The firstth, adopt the pipe ring of manpower type to walking mechanism, will be actually used in the instrument of processing, such as flame cutting torch, welding rifle, spray gun etc. is installed on pipe ring on walking mechanism, and then manual drive walking mechanism is done hoop motion, completes processing action.The key issue of this mode is that the speed of walking is uncontrollable, the quality of processing is difficult to guarantee, because quality and the speed of welding, cutting, spraying have very strong dependence, in addition, when walking mechanism runs to duct bottom or some specific position, operator possibly cannot touch, and this has brought a lot of inconvenience to actual production;
The secondth, magnetic-type walking mechanism, this mode is simple in structure, be mainly used in the cutting field of pipeline, the shortcoming that this mode is applied to the field of cutting has, and 1, in the bad situation of steel pipe ovality, magnetic trolley is walked along tube wall, walking path changes, particularly large-diameter steel pipe, welds rear ovality and is difficult to keep fine, and cutting effect is bad.2, on surface, have in the situations such as coating or heat-insulation layer, magnetic force reduces, and cannot overcome deadweight, and magnetic-type cannot be worked.3, be cut with slit-tube particularly during helix tube, magnetic-type run trace changes, and magnetic trolley is easily falling down through the commissure of helix tube or owing to jolting, walking mechanism wheel wanders off.4, the nonmagnetic pipeline such as stainless steel can not cut.When 5, magnetic cutting machine is placed on pipe, be difficult to guarantee the parallel of cutting body and pipe end face, walking deviation is inevitable, caliber is larger, deviation is larger, therefore usually first setting-out, is monitored by workman in cutting process more in real time, occurs deviation manually intervention again, waste man-hour, can not thoroughly ensure the quality of products again simultaneously.
The 3rd, chain-type automatic traveling mechanism, has space between this mode 1, chain section and joint, uses chain as track, is difficult to guarantee walking precision.Steel pipe bore is larger, and error is larger; 2, before every task, chain all wants one to save installation, and chain relaxes in installation process, and mounted chain link easily comes off, and installation is wasted time and energy, and easily aggravates above-mentioned 1 shortcoming.
The 4th is locating piece formula automatic traveling mechanism, and this mode is located standard, but manufacturing cost is high, equipment weight, and parts are many, and installation is wasted time and energy.
Summary of the invention
The present invention is directed to shortcomings and deficiencies of the prior art, provide portable pipe automatic ring to walking arrangement and pipeline processing method, hoop walking demand for pipeline processing and construction field, can meet pipe ring especially to the requirement of the processing such as cutting, welding, surface apply.Can improve well the precision of hoop walking, install very conveniently, automaticity is high, and the pipeline of different-diameter scope is had to very strong adaptability, convenient flexibly.
