DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] An embodiment of the utility model provides a large-diameter steel pipe processing and grinding device, as Figures 1-4 shown, which includes a support mechanism 1. One end of the top of the support mechanism 1 is fixedly connected with an inner grinder 2, and an outer grinder 3 is slidably connected inside one side of the support mechanism 1.

[0022] It should be noted that due to the large mass of the existing large-diameter steel pipe, it is difficult to perform rotation operations during the processing, which to a certain extent affects the processing efficiency. In this solution, the steel pipe is driven to rotate by multiple support rollers 13, so that the equipment can perform non-dead-angle grinding on the steel pipe during the grinding process. By adjusting the inner grinding wheel 211 and the outer grinding wheel 34, the device can process steel pipes of different diameters.

[0023] Specifically, in this embodiment, this solution mainly includes a support mechanism 1. One end of the top of the support mechanism 1 is fixedly connected with an inner grinder 2, and an outer grinder 3 is slidably connected inside one side of the support mechanism 1. The steel pipe is placed between multiple support blocks 12, and multiple support rollers 13 support the steel pipe. The rotation of multiple support rollers 13 drives the steel pipe to rotate on the top of the bottom plate 11. Start the driving wheel 25 to rotate, so that the driving wheel 25 drives the adjusting rod 26 to slide inside the through hole 22, thereby adjusting the length of the adjusting rod 26 extending into the steel pipe. When the end of the adjusting rod 26 reaches a suitable position inside the steel pipe, start the hydraulic rod 28, so that the hydraulic rod 28 drives the support piece 29 to fit against the inner wall of the steel pipe. When the outer grinder 3 moves to a suitable position, make the rotating rod 33 rotate around the top of the moving block 31, so that the outer grinding wheel 34 contacts the outer wall of the steel pipe. The steel pipe is driven to rotate by the support rollers 13, thereby grinding the outer wall of the steel pipe.

[0024] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, the support mechanism 1 includes a bottom plate 11. A support block 12 is fixedly connected to the top of the bottom plate 11. Two support rollers 13 are fixedly connected inside the support block 12. The two support rollers 13 are distributed at different heights inside the support block 12. There are multiple support blocks 12, and the multiple support blocks 12 are symmetrically distributed on both sides of the top of the bottom plate 11. An installation block 14 is fixedly connected to one side of the bottom plate 11. A chute 15 is provided inside the installation block 14. Rotation holes 16 are provided at both ends of the chute 15. A lead screw 17 is rotatably connected inside the two rotation holes 16. One end of the lead screw 17 is fixedly connected to a motor 18. First, place the steel pipe between the multiple support blocks 12, so that the multiple support rollers 13 support the steel pipe, and drive the steel pipe to rotate on the top of the bottom plate 11 by the rotation of the multiple support rollers 13.

[0025] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, the internal grinding device 2 includes a fixed block 21. A through hole 22 is provided inside the fixed block 21. Positioning strips 23 are fixedly connected to both sides of the through hole 22. A plurality of fixed shafts 24 are fixedly connected to the upper and lower sides inside the through hole 22. Driving wheels 25 are rotatably connected to the outside of the fixed shafts 24. An adjusting rod 26 is slidably connected inside the through hole 22. Positioning grooves 27 are provided on both sides of the adjusting rod 26, and both of the two positioning grooves 27 are slidably connected to the positioning strips 23. A hydraulic rod 28 is fixedly connected to the top of one end of the adjusting rod 26. A support piece 29 is fixedly connected to the top of the hydraulic rod 28. An expansion rod is provided inside one end of the adjusting rod 26. A connecting block 210 is fixedly connected to the bottom of the expansion rod. An internal grinding wheel 211 is rotatably connected inside the connecting block 210. First, start the rotation of the driving wheels 25, so that the driving wheels 25 drive the adjusting rod 26 to slide inside the through hole 22, thereby adjusting the length of the adjusting rod 26 extending into the steel pipe. When the end of the adjusting rod 26 reaches a suitable position inside the steel pipe, start the hydraulic rod 28, so that the hydraulic rod 28 drives the support piece 29 to fit against the inner wall of the steel pipe. At this time, start the expansion rod at the end of the adjusting rod 26, so that the connecting block 210 drives the internal grinding wheel 211 to fit against the inner wall of the steel pipe. At this time, start the internal grinding wheel 211 to grind the inside of the steel pipe.

[0026] In a further preferred embodiment of the present utility model, as Figures 1-4As shown in the figure, the external grinding device 3 includes a moving block 31. A support rod 32 is fixedly connected to the top of the moving block 31. A rotating rod 33 is rotatably connected inside the support rod 32. An external grinding wheel 34 is rotatably connected inside one end of the rotating rod 33 away from the support rod 32. The moving block 31 is slidably connected inside the chute 15. The inside of the moving block 31 is threadedly connected to the lead screw 17. First, start the motor 18 to drive the lead screw 17 to rotate, so that the lead screw 17 drives the moving block 31 to slide inside the chute 15, and adjust the position of the external grinding device 3 on the top of the bottom plate 11. When the external grinding device 3 moves to a suitable position, make the rotating rod 33 rotate around the top of the moving block 31, so that the external grinding wheel 34 contacts the outer wall of the steel pipe. Drive the steel pipe to rotate through the support roller 13, so as to grind the outer wall of the steel pipe.
