Detailed description of the invention
As shown in figures 1 to 6, the outer anti-corrosion insulating layer remover of a kind of pipeline of the present invention, including the detent mechanism being located in pipeline and delivering gear.
Detent mechanism includes T-shaped platform 9, wedge 8, conically shaped 7, central canal 5, promotes nut 10, lead-screw 6 as shown in figures 1 to 6.Central canal 5 is coaxially disposed with pipeline.The groove of band tapering it is provided with on conically shaped 7, it is provided with through hole on wedge 8, wedge 8 can slide in groove, it is provided with external screw thread on central canal 5, conically shaped 7 is fixed together with central canal 5, conically shaped 7 is internally provided with lead-screw 6 with central canal 5, and lead-screw 6 is connected with promoting nut 10 by screw thread, promotes the finger tip of nut 10 then through the through hole of wedge 8.
Preferably, described lead-screw 6 can rotate in described conically shaped 7, with drive promotion nut 10 along lead-screw 6 axially-movable, and then drives wedge 8 to slide in conically shaped 7 groove.
Preferably, the quantity of wedge 8 is more than three, is uniformly arranged along conically shaped 7 surface.
Delivering gear includes manual rocker 4 and support 2 as shown in figures 1 to 6, and manual rocker 4 is provided with internal thread hole and handle, and the female thread of manual rocker 4 matches with the external screw thread of central canal 5.Support 2 direction axially along the pipe is arranged, and support 2 one end is fixing with manual rocker 4 to be connected, and the other end is fixed with removing cutter 1, support 2 is provided with two installing holes, and cutter is fixed on support 2 by screw 3.
The use process that outside a kind of pipeline of the present invention, anti-corrosion insulating layer detacher is concrete is: uses the instruments such as spanner and rotates lead-screw 6, lead-screw 6 drives and promotes nut 10 to advance, nut 10 is promoted to drive wedge 8 with promoting nut 10 to advance in the groove of conically shaped 7 by the effect of finger tip and wedge 8 hole, effect due to tapering, multiple wedges 8 open while advancing together, thus conically shaped 7 and central canal 5 are fixed on the inwall of pipeline.
For the installation of applicable different inner diameters pipeline, wedge 8 needs to coordinate the T-shaped platform 9 of differing heights, internal diameter of the pipeline to change the T-shaped platform 9 then selecting suitably height.When central canal 5 is after inner-walls of duct fixes, the inner hole sleeve of manual rocker 4 is screwed according to thread fiting mode on central canal 5, the regulation support 2 position on manual rocker 4, make the appropriate depth of the point of a knife incision outer anti-corrosion insulating layer of contact pipeline of cutter 1, being fixed on manual rocker 4 with 3 supports 2 of screw, the length of manual rocker 4 also adapts with caliber.When rotation manual rocking bar 4, cutter 1 i.e. rotates the cutting realizing anti-corrosion insulating layer outer to pipeline under the drive of manual rocker 4 and support 2 around central canal 5, manual rocker 4 is under the effect of the screw thread of central canal 5 simultaneously, and band cutter 1 is along central canal 5 axially-movable, it is achieved the autofeed of cutter 1.The width of the outer anti-corrosion insulating layer of stripping channel determines manual rocker 4 distance of precession on central canal 5 as required.
The present invention is cooperated with conically shaped by three pieces of wedges, realize the self-centering of central canal and fix, manual rocker uses threaded connection mode with central canal, manual rocker also produces axially-movable while central canal rotates, utilizing rotation and the axially-movable of manual rocker, the cutter holding mechanism band cutter being fixed on manual rocker realizes cutting and the autofeed of anti-corrosion insulating layer outer to pipeline.
The above, it it is only presently preferred embodiments of the present invention, not the present invention is made any pro forma restriction, although the present invention is disclosed above with preferred embodiment, but it is not limited to the present invention, any those skilled in the art, in the range of without departing from technical solution of the present invention, when the technology contents of available the disclosure above makes a little change or is modified to the Equivalent embodiments of equivalent variations, in every case it is without departing from technical solution of the present invention content, any simple modification above example made according to the technical spirit of the present invention, equivalent variations and modification, all still fall within the range of technical solution of the present invention.
