Detailed description of the invention
As shown in Fig. 1-6, the outer anti-corrosion insulating layer remover of a kind of pipeline of the present invention, comprises detent mechanism and the delivering gear be located in pipeline.
As shown in Fig. 1-6, detent mechanism comprises T-shaped platform 9, wedge 8, conically shaped 7, central tube 5, promotes nut 10, lead-screw 6.Central tube 5 coaxially arranges with pipeline.On conically shaped 7, be provided with the groove with tapering, on wedge 8, be provided with through hole, wedge 8 can slide in groove, on central tube 5, be provided with external screw thread, conically shaped 7 is fixed together with central tube 5, conically shaped 7 is provided with lead-screw 6 with the inside of central tube 5, and lead-screw 6 is connected with promotion nut 10 by screw thread, and the finger tip that promotes nut 10 passes the through hole of wedge 8.
Preferably, described lead-screw 6 can, in the interior rotation of described conically shaped 7, promote nut 10 along lead-screw 6 axially-movables to drive, and then drive wedge 8 to slide in conically shaped 7 grooves.
Preferably, the quantity of wedge 8 is more than three, along conically shaped 7 surface uniform settings.
As shown in Fig. 1-6, delivering gear comprises manual rocking bar 4 and support 2, manually on rocking bar 4, is provided with internal thread hole and handle, and manually the internal thread of rocking bar 4 and the external screw thread of central tube 5 match.Support 2 arranges along pipeline axial direction, and support 2 one end are fixedly connected with manual rocking bar 4, be fixed with and remove cutter 1 on the other end, are provided with two installing holes on support 2, and cutter is fixed on support 2 by screw 3.
The outer concrete use procedure of anti-corrosion insulating layer stripper of a kind of pipeline of the present invention is: use the instruments such as spanner and rotate lead-screw 6, lead-screw 6 drives promotion nut 10 to advance, promoting nut 10 drives wedge 8 to advance in the groove of conically shaped 7 with promoting nut 10 by the effect in finger tip and wedge 8 holes, due to the effect of tapering, multiple wedges 8 open together in advancing, thereby conically shaped 7 and central tube 5 are fixed on to the inwall of pipeline.
For being applicable to the installation of different inner diameters pipeline, wedge 8 need to coordinate the T-shaped platform 9 of differing heights, and internal diameter of the pipeline changes the T-shaped platform 9 of selecting suitable height.When central tube 5 is after inner-walls of duct fixes, the inner hole sleeve that handle shakes bar 4 screws according to thread fiting mode on central tube 5, regulate the position of support 2 on manual rocking bar 4, make the appropriate depth of the outer anti-corrosion insulating layer of point of a knife incision contact pipeline of cutter 1, support 2 is fixed on manual rocking bar 4 with screw 3, manually the length of rocking bar 4 also adapts with caliber.In the time of rotation manual rocking bar 4, the i.e. cutting of anti-corrosion insulating layer outside central tube 5 rotations realize pipeline under the drive of manual rocking bar 4 and support 2 of cutter 1, manually rocking bar 4 is under the effect of the screw thread of central tube 5 simultaneously, and band cutter 1, along central tube 5 axially-movables, is realized the autofeed of cutter 1.The width of the outer anti-corrosion insulating layer of stripping channel decides the distance of manual rocking bar 4 precession on central tube 5 as required.
The present invention cooperatively interacts by three wedges and conically shaped, realize the self-centering of central tube and fix, manually rocking bar and central tube adopt threaded connection mode, manually rocking bar also produces axially-movable in the time that central tube rotates, utilize rotation and the axially-movable of manual rocking bar, the cutter holding mechanism being fixed on manual rocking bar realizes cutting and the autofeed to the outer anti-corrosion insulating layer of pipeline with cutter.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, but not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be not depart from technical solution of the present invention content, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
