[0020] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] ReferenceFigure 1 - Figure 5 As shown in the figure, the present invention provides a technical solution: a surface grinding device for steel-plastic composite pipes, including a placement rack 1. The top end of the placement rack 1 is fixedly connected with a top plate 2. The rear end of the top plate 2 is fixedly connected with a central frame 3. The top end of the central frame 3 is fixedly connected with a pipe placement block 4. A grinding mechanism 5 is installed at the top end of the top plate 2. Adjusting arms 6 are fixedly connected to the four sides of the central frame 3. A regulating column 7 is fixedly connected to the side of the adjusting arm 6 close to the pipe placement block 4. A rotating column 8 is rotatably connected inside the regulating column 7. An extending column 9 is arranged inside the rotating column 8. A deviation-correcting plate 10 is fixedly connected to the side of the extending column 9 away from the regulating column 7. Adjusting grooves 11 are formed at both ends of the rotating column 8. A round block 12 is slidably connected inside the adjusting groove 11. A plug rod 13 is fixedly connected to the side of the round block 12 close to the adjusting groove 11. A number of plug slots 14 are formed inside the extending column 9. Arc-shaped blocks 15 are fixedly connected to both ends inside the regulating column 7. The staff rotates the rotating column 8 to drive the round block 12 and the plug rod 13 to move, and makes the round block 12 contact the arc-shaped block 15. When the round block 12 contacts the thicker end of the arc-shaped block 15, the arc-shaped block 15 pushes the round block 12 to drive the plug rod 13 to insert into the plug slot 14 to fix the position of the extending column 9. Through the above settings, it is convenient for the staff to perform guiding grinding on steel-plastic composite pipes with different outer diameters.

[0022] Refer to Figure 3 As shown in the figure, in this embodiment: the size of the plug rod 13 is adapted to the size of the plug slot 14, and the surface of the plug rod 13 is inserted into the inside of the plug slot 14. Through the setting that the size of the plug rod 13 is adapted to the size of the plug slot 14, the plug rod 13 can be stably inserted into the inside of the plug slot 14, thereby realizing the stable connection between the extending column 9 and the regulating column 7, avoiding shaking or falling off during use, and thus ensuring the stability and reliability of the entire device.

[0023] Refer to Figure 1 As shown in the figure, in this embodiment: a plurality of rollers are arranged on the side of the deviation-correcting plate 10 close to the pipe placement block 4. Through the setting that a plurality of rollers are arranged on the side of the deviation-correcting plate 10 close to the pipe placement block 4, the deviation-correcting plate 10 can move smoothly on the surface of the steel-plastic composite pipe, thereby ensuring the uniformity and consistency of grinding. At the same time, the setting of a plurality of rollers can also effectively reduce the friction between the deviation-correcting plate 10 and the steel-plastic composite pipe, making the grinding process smoother, reducing energy consumption and noise.

[0024] Refer to Figure 3As shown, in this embodiment: two annular grooves 16 are opened on the inner wall of the adjusting column 7, and a ring block 17 is fixedly connected to the outer diameter surface of the rotating column 8, and the surface of the ring block 17 is slidably connected to the inside of the annular groove 16. When the staff rotates the rotating column 8, the rotating column 8 drives the ring block 17 to rotate inside the annular groove 16. Through the above arrangement, not only the stable rotation of the rotating column 8 is achieved, but also the ring block 17 can limit the rotating column 8 during the sliding process inside the annular groove 16, thereby preventing the rotating column 8 from deviating or shaking during the rotation process, thereby further improving the overall stability and practicality.

[0025] Reference Figure 3 As shown, in this embodiment: slide grooves 18 are provided on both sides of the adjusting groove 11, and sliders 19 are fixedly connected on both sides of the round block 12. The surface of the slider 19 is slidably connected to the inside of the slide groove 18. When the staff moves the round block 12, the round block 12 drives the slider 19 to slide in the slide groove 18. Through the above arrangement, the round block 12 can be made more stable when moving, and there will be no deviation or shaking, thereby improving the overall stability and reliability. At the same time, the sliding connection design between the slider 19 and the slide groove 18 also makes the movement of the round block 12 smoother, reduces friction and resistance, and further improves the use efficiency.

[0026] Reference Figure 3 As shown, in the present embodiment: a side of the round block 12 close to the insertion rod 13 is fixedly connected with a force storage spring 20, and a side of the force storage spring 20 away from the round block 12 is fixedly connected to the inside of the adjustment slot 11. When the staff causes the round block 12 to push the insertion rod 13, the insertion rod 13 squeezes the force storage spring 20 for compression and force storage, and drives the insertion rod 13 to be inserted into the slot 14 for fixation. When the staff causes the round block 12 to cancel contact with the arc block 15, the insertion rod 13 will be quickly ejected under the action of the rebound force of the force storage spring 20, so that the limit between the insertion rod 13 and the slot 14 is cancelled, so that the staff can quickly adjust the position of the extension column 9.

[0027] Reference Figure 5 As shown, in this implementation scheme: a side of the adjusting column 7 close to the annular groove 16 is fixedly connected with a return spring 21, and a side of the return spring 21 away from the adjusting column 7 is fixedly connected to the annular groove 16. When the staff rotates the rotating column 8, the rotating column 8 drives the ring block 17 to twist the return spring 21 to store force, and drives the round block 12 to release the contact with the arc block 15. The storage spring 20 pushes the round block 12 to drive the insertion rod 13 to release the limit between the slot 14. When the staff releases the rotating column 8, the rotating column 8 is quickly reset under the action of the rebound force of the return spring 21, and the round block 12 is made to contact the arc block 15 again, so that the insertion rod 13 is inserted into the slot 14 to limit the extension column 9.

[0028] Working principle: The staff drives the round block 12 and the insertion rod 13 to move by rotating the rotating column 8, and makes the round block 12 contact with the arc-shaped block 15. When the round block 12 contacts the thicker end of the arc-shaped block 15, the arc-shaped block 15 pushes the round block 12 to drive the insertion rod 13 to insert into the slot 14 to fix the position of the extension column 9. Through the above settings, it is convenient for the staff to guide and polish the steel-plastic composite pipes with different outer diameters. By setting the size of the insertion rod 13 to match the size of the slot 14, the insertion rod 13 can be stably inserted into the inside of the slot 14, thereby realizing the stable connection between the extension column 9 and the adjustment column 7, avoiding shaking or falling off during use, and thus ensuring the stability and reliability of the entire device. By setting multiple rollers on the side of the deviation correction plate 10 close to the pipe placement block 4, the deviation correction plate 10 can move smoothly on the surface of the steel-plastic composite pipe, thereby ensuring the uniformity and consistency of polishing. At the same time, the setting of multiple rollers can also effectively reduce the friction between the deviation correction plate 10 and the steel-plastic composite pipe, making the polishing process smoother, reducing energy consumption and noise. When the staff rotates the rotating column 8, the rotating column 8 drives the ring block 17 to rotate inside the ring groove 16. Through the above settings, not only the stable rotation of the rotating column 8 is realized, but also during the sliding process of the ring block 17 inside the ring groove 16, the ring block 17 can play a limiting role on the rotating column 8, preventing the rotating column 8 from shifting or shaking during rotation, and further improving the overall stability and practicality. When the staff moves the round block 12, the round block 12 drives the slider 19 to slide inside the chute 18. Through the above settings, the round block 12 can move more stably during movement, without shifting or shaking, thereby improving the overall stability and reliability. At the same time, the sliding connection design of the slider 19 and the chute 18 also makes the movement of the round block 12 smoother, reducing friction and resistance, and further improving the use efficiency. When the staff uses the round block 12 to push the insertion rod 13, the insertion rod 13 compresses the energy storage spring 20 for energy storage and drives the insertion rod 13 to insert into the slot 14 for fixation. When the staff cancels the contact between the round block 12 and the arc-shaped block 15, under the action of the resilience of the energy storage spring 20, the insertion rod 13 will be quickly ejected, canceling the limit between the insertion rod 13 and the slot 14, so that the staff can quickly adjust the position of the extension column 9. When the staff rotates the rotating column 8, the rotating column 8 drives the ring block 17 to twist the return spring 21 for energy storage, and drives the round block 12 to cancel the contact with the arc-shaped block 15. The energy storage spring 20 pushes the round block 12 to drive the insertion rod 13 to cancel the limit with the slot 14. When the staff releases the rotating column 8, under the action of the resilience of the return spring 21, the rotating column 8 is quickly reset, and the round block 12 contacts the arc-shaped block 15 again, so that the insertion rod 13 inserts into the slot 14 to limit the extension column 9.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
