Description
Technical field
The invention belongs to transportation pipe line detection field, be specifically related to the input advancing means of flux leakage detector in a kind of pipeline.
Background technique
Transportation pipe line laid and use a period of time after all need to detect, detection method in using at present more, that is: pipe leakage detector is rendered in tested pipeline, by gas or fluid pressure differential, driven it is walked at pipeline internal, thereby complete the detection of pipeline.Because flux leakage detector magnetic attraction in pipeline is large, add that weight own is larger, make detector when throwing in, there is very large difficulty in pipeline, if carry out submerged pipeline detection, offshore platform working space is narrow and small, and operation easier is larger, and has certain danger.The method adopting at present comprises: people's force method, and many people are thrown in into joint efforts, and safety coefficient is low and cost of labor is high; Oil cylinder or cylinder top pushing manipulation, possibility large and that exist input to lose efficacy takes up room.
Summary of the invention
The object of the present invention is to provide the input advancing means of flux leakage detector in a kind of pipeline, to solve the scene of pipe leakage detector, throw in problem, this input advancing means has easy and simple to handle, and the little feature that takes up room can realize the smooth input of flux leakage detector.
In pipeline of the present invention flux leakage detector throw in advancing means mainly by lead-screw driving device, solid piece, bracket, push rod, leading screw, baffle plate, partly cut open pipe and variable cross section dispenser and form; Bracket and partly cut open tube section and be arc-shaped structure wherein, and partly cut open tube body and abut in bracket inwall and form and be slidably matched; One end of partly cuing open pipe is fixed with baffle plate, the fixing solid piece in one end of bracket; One end of leading screw is fixed by the through hole on solid piece and baffle plate, and the other end and lead-screw driving device are threaded connection, and one end of push rod is leading screw pattern, by screw thread, is connected with solid piece, and the other end is polished rod pattern, and through the through hole on baffle plate; The CONCENTRIC REDUCER structure of described variable cross section dispenser for connecting by varying cross-section duct, variable cross section dispenser bottom is horizontal structure, its large and small end section is round structure, and holds greatly radius to be not less than bracket radius, and small end radius is identical with detected pipeline radius.
The Placement of leading screw and baffle plate is for being fixedly connected with or screw thread links.Such as following Placement: securing cover plate on baffle plate, the two space surrounding is embedded with end plate, and leading screw is connected with end plate after through the through hole on cover plate, and clear size of opening is less than end plate.
Compared with prior art, the present invention can be by flux leakage detector by operation lead-screw driving device and is partly cutd open pipe and render in variable cross section dispenser, utilize push rod by flux leakage detector fixed position, by lead-screw driving device, will partly cut open pipe again hauls out, can realize the input work to flux leakage detector, whole process a people can complete, and has the features such as the reliability of input is high, easy and simple to handle, can effectively reduce site operation personnel's working strength, raise the efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the input advancing means of flux leakage detector in pipeline;

Wherein: 1, lead-screw driving device; 2, solid piece; 3, bracket; 4, push rod; 5, leading screw; 6, cover plate; 7, end plate; 8, baffle plate; 9, partly cut open pipe; 10, flux leakage detector; 11, variable cross section dispenser.
Embodiment
Now in conjunction with Figure of description 1, the invention will be further described for accompanying drawing 2.
Throw in advancing means by lead-screw driving device 1, solid piece 2, bracket 3, push rod 4, leading screw 5, cover plate 6, end plate 7, baffle plate 8, partly cut open pipe 9, variable cross section dispenser 11 forms, itself and flux leakage detector 10 are used in conjunction with.Bracket 3, partly cut open pipe 9 sectional shapes be arc-shaped structure, partly cut open pipe 9 radiuses and be less than bracket 3 radiuses, partly cut open that pipe 9 can be positioned on bracket 3 and slidably, the large end of variable cross section dispenser 11 is round structure, radius is not less than bracket radius, and small end is round structure, and radius is identical with detected pipeline radius, between large end and small end, by varying cross-section duct, connect, bottom is horizontal structure.Bracket 3 and variable cross section dispenser 11 horizontal alignments, flux leakage detector 10 is positioned over and partly cuts open on pipe 9, partly cuts open pipe 9 and is slidably matched with bracket 3 and variable cross section dispenser 11; Lead-screw driving device 1 is fixed on solid piece 2, Gu piece 2 is fixed on the left end of bracket 3; Baffle plate 8 has through hole and is fixed on and partly cuts open on pipe 9, and leading screw 5 left ends are threaded connection through solid piece 2 through holes and lead-screw driving device 1, and right-hand member and baffle plate 8 are fixing.Push rod 4 left ends are leading screw pattern, by screw thread, are connected with solid piece 2; Right-hand member is polished rod pattern, through the through hole on baffle plate 8, contacts with flux leakage detector 10 tail ends.
Leading screw 5 right-hand members can be fixedly connected with for welding waits with the Placement of baffle plate 8; Also can be for being threaded; Or on leading screw 5, increase a cover plate 6, cover plate 6 is preferably disc, cover plate 6 is connected with baffle plate 8 by bolt, on cover plate 6, have through hole, leading screw 5 is fixed an end plate 7 through after the through hole of cover plate 6 at low order end, in the space that end plate 7 surrounds at cover plate 6 and baffle plate 8, size is less than cover plate 6 and is greater than the through-hole diameter of cover plate 6.
The effect of throwing in advancing means is exactly to realize flux leakage detector to the input of variable cross section dispenser by operating respectively the motion of leading screw and push rod.Concrete operation process is: lead-screw driving device 1 is fixed on solid piece 2, Gu piece 2 is fixed on the left end of bracket 3, baffle plate 8 has through hole and is fixed on and partly cuts open on pipe 9, on cover plate 6, have through hole and be connected with baffle plate 8 by bolt, end plate 7 is cylindrical and is fixed on the low order end of leading screw 5, Gu piece 2 tops have the silk hole corresponding with push rod 4, bottom has can be through the through hole of leading screw 5, when operation starts, adjusting successively bracket 3 aligns with variable cross section dispenser 11, flux leakage detector 10 is placed on and is partly cutd open on pipe 9, partly cuing open pipe 9 is placed on bracket 3, startup lead-screw driving device 1 drives leading screw 5 to promote partly to cut open pipe 9 and moves on in variable cross section dispenser 11 from bracket 3, and make driving leather cup on flux leakage detector 10 be adjacent to the inwall of variable cross section dispenser 11, again push rod 4 is held out against to the tail end of flux leakage detector 10 through the through hole on baffle plate 8, start lead-screw driving device 1 running in the other direction, driving leading screw 5 will partly cut open pipe 9 pulls out, regain push rod 4, so, complete the input work of flux leakage detector 10.
