[0002] During the processing, transportation and storage of petroleum pipeline, scale, oil stains, rust and other impurities may form on the pipe orifice surface. These impurities can hinder the fusion of metal during welding, leading to welding defects. Therefore, it is necessary to quickly polish the pipe orifice of the pipeline.

[0003] After searching, the patent document with publication number CN216371426U discloses a pipe orifice polishing device for petroleum pipeline processing. The petroleum pipe can move back and forth on the sliding groove under the action of the roller, and the threaded fixing rod at the top of the petroleum pipe provides good fixation for the petroleum pipe. In addition, a water sprayer is installed at the top inside the device housing, which can reduce or lower the dust generated during polishing and the heat generated by the petroleum pipe.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a grinding device for the nozzle of an oil pipeline.

[0027] This utility model provides, for example Figures 1-3 The grinding device for the inlet of an oil pipeline shown includes a grinding frame 1. A support column 2 is fixedly installed on the upper end of the inner wall of the grinding frame 1. A drive motor 3 is fixedly installed at the end of the support column 2. A connecting plate 4 is fixedly sleeved on the output shaft of the drive motor 3. An adjustment mechanism is provided on the side of the connecting plate 4, and a moving plate 5 is provided through the adjustment mechanism. A rotating rod 6 is rotatably inserted through the upper end of the moving plate 5. A grinding wheel 7 is fixedly sleeved at the end of the rotating rod 6. Multiple drive gears 8 are sleeved on the outer wall of the support column 2. A transmission gear 9 is fixedly sleeved on the rod wall of the rotating rod 6.

The sleeve 14 is slidably sleeved on the outside of the support column 2. A tightening bolt 15 is threaded through the tube wall of the sleeve 14. The end of the tightening bolt 15 abuts against the outer wall of the support column 2.

[0028] The adjustment mechanism includes an adjustment screw 11. A groove is provided on the outer wall of the connecting plate 4. The adjustment screw 11 is rotatably disposed in the groove. A sliding plate 12 is threaded onto the wall of the adjustment screw 11. The outer wall of the sliding plate 12 contacts and engages with the inner side wall of the groove. The sliding plate 12 is fixedly inserted into the interior of the movable plate 5. The top of the adjustment screw 11 extends out of the connecting plate 4 and is fixedly provided with a knob 13.

[0029] First, according to the pipe diameter of the petroleum pipeline to be polished, the position of the polishing wheel is adjusted, the knob is rotated 13, the knob drives the adjusting screw 11 to rotate, because the sliding plate 12 is screwed with the adjusting screw 11, and the sliding plate 12 is fixedly provided in the moving plate 5, and the outer wall of the sliding plate 12 is in contact with the inner wall of the groove, the sliding plate 12 will move up and down in the groove with the rotation of the adjusting screw 11, and then drive the moving plate 5 and the polishing wheel 7 to move up and down, so as to adjust the relative position of the polishing wheel 7 and the pipe opening of the petroleum pipeline, and adapt to petroleum pipelines with different diameters, then the petroleum pipeline is placed in the clamping cavity 10 for clamping, then the driving motor 3 is started, the output shaft of the driving motor 3 drives the connecting plate 4 to rotate, the connecting plate 4 drives the moving plate 5 and the polishing wheel 7 to revolve around the petroleum pipeline opening when rotating, at the same time, the driving gear 8 sleeved on the outer wall of the supporting column 2 will rotate with the connecting plate 4, because the driving gear 8 is matched with the transmission gear 9 fixedly sleeved on the rod wall of the rotating rod 6, and the outer diameters of the plurality of driving gears 8 are different, the driving gear 8 with the appropriate outer diameter is selected, and it is fixed on the supporting column 2 through the abutting bolt 15, the driving gear 8 drives the transmission gear 9 to rotate when rotating, and then the rotating rod 6 and the polishing wheel 7 rotate themselves. In this way, the polishing wheel 7 revolves along the pipe opening while rotating itself, realizing uniform polishing of the pipe opening;

[0030] At the same time, during the polishing process, if it is necessary to change the rotating speed of the polishing wheel 7 to adapt to different polishing requirements, the abutting bolt 15 can be loosened, the sleeve pipe 14 is slid, the driving gear 8 with different outer diameter is replaced, and then the abutting bolt 15 is tightened again to fix the driving gear 8, so as to change the transmission ratio of the driving gear 8 and the transmission gear 9, realizing the adjustment of the rotating speed of the polishing wheel 7.

[0032] After the position of the polishing wheel is adjusted, the petroleum pipeline is placed in the clamping cavity 10, the rotating block 17 is rotated, the rotating block drives the bidirectional screw rod 16 to rotate, the screw threads at both ends of the rod wall of the bidirectional screw rod 16 are opposite, so the clamping plates 18 threadedly sleeved at both ends will move closer to or away from each other with the rotation of the bidirectional screw rod 16, because the clamping plate 18 is an arc-shaped clamping plate, its end is in contact with the inner wall of the clamping cavity 10, so when the clamping plates 18 move closer to each other, the petroleum pipeline can be centered and stably clamped, ensuring the stability during polishing.

[0033] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
