[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0023] like Figures 1 to 5 As shown, the steel pipe grinding machine 100 of the embodiment of the utility model comprises a workbench 1, a first rotating shaft 2, a first motor 3, a support cylinder 4, a plurality of rollers 5, a grinding wheel 6, and a second motor 7. The first rotating shaft 2 is rotatably arranged on the workbench 1 along the length direction of the workbench 1, the first motor 3 is arranged on the workbench 1 and connected to the first rotating shaft 2 to drive the first rotating shaft 2 to rotate, and the support cylinder 4 is sleeved on the first rotating shaft 2. A plurality of rollers 5 are arranged at intervals along the axial direction of the first rotating shaft 2, the axial direction of the rollers 5 is horizontally arranged and is arranged at an angle to the axial direction of the first rotating shaft 2, and the support cylinder 4 cooperates with the rollers 5 to support the movement of the steel pipe 200 to be grinded. The grinding wheel 6 is arranged above the support cylinder 4 and the rollers 5 and is rotatably connected to the workbench 1, the second motor 7 is arranged on the workbench 1 and connected to the grinding wheel 6 to drive the grinding wheel 6 to rotate, and the grinding wheel 6 is used to grind the steel pipe 200 to be grinded placed on the support cylinder 4 and the rollers 5.

[0024] During the use of the steel pipe grinding machine 100 of the embodiment of the utility model, the steel pipe 200 to be polished is placed on the roller 5 and the support tube 4, and the axial direction of the steel pipe 200 to be polished is parallel to the axial direction of the first rotating shaft 2, and the first motor 3 drives the first rotating shaft 2 to rotate, and the first rotating shaft 2 drives the support tube 4 to rotate. Since there is friction between the steel pipe 200 to be polished and the support tube 4, the support tube 4 can drive the steel pipe 200 to be polished to rotate, and since the axial direction of the roller 5 is horizontally arranged and is arranged at an angle to the axial direction of the first rotating shaft 2, the steel pipe 200 to be polished can move toward the grinding wheel 6 under the guidance of the roller 5 while rolling, so that the steel pipe 200 to be polished automatically moves and passes under the grinding wheel 6. When the steel pipe 200 to be polished passes under the grinding wheel 6, the grinding wheel 6 performs grinding on the steel pipe 200 to be polished. The entire grinding process does not require manual operation by personnel, and the degree of automation is high, which greatly reduces the labor intensity of workers and avoids the operational safety risks caused by manual operation. In addition, the distance between the grinding wheel 6 and the steel pipe 200 to be ground is fixed, so that the rust removal quality is stable and the rust removal effect is good, thereby improving the service life and later appearance of the steel pipe.

[0025] In some embodiments, the steel pipe grinder 100 of the utility model embodiment also includes a second rotating shaft (not shown in the figure) and a support frame 9. The second rotating shaft is rotatably arranged on the workbench 1 along the vertical direction. The roller 5 is connected to the second rotating shaft through the support frame 9. The rotation of the second rotating shaft can adjust the angle between the axial direction of the roller 5 and the axial direction of the first rotating shaft 2 to change the moving speed of the steel pipe 200 to be grinded, thereby facilitating the adjustment of the feed speed of the steel pipe 200 to be grinded.

[0026] In some embodiments, the steel pipe grinding machine 100 of the utility model embodiment further includes an adjustment component, which includes an adjustment plate 10, which extends along the axial direction of the first rotating shaft 2 and is adjustable along the axial position of the first rotating shaft 2, and the adjustment plate 10 is rotatably connected to the support frame 9 of each roller 5, and the adjustment plate 10 is moved to adjust the angle between the axial direction of the roller 5 and the axial direction of the first rotating shaft 2. By setting the adjustment plate 10 to synchronously adjust the angle of each roller 5, the angle adjustment of the roller 5 is convenient and quick, and the feed speed adjustment of the steel pipe 200 to be polished is convenient and quick.

[0027] In some embodiments, Figure 4 and Figure 5 As shown, the adjustment component also includes a rack 11 and a gear 12. The rack 11 is connected to the adjustment plate 10 and extends along the axial direction of the first rotating shaft 2. The gear 12 is rotatably arranged on the workbench 1 and meshes with the rack 11. By rotating the gear 12, the gear 12 rotates and drives the rack 11 to move in the axial direction of the first rotating shaft 2. The movement of the rack 11 drives the adjustment plate 10 to move in the axial direction of the first rotating shaft 2 to adjust the angle of the roller 5. The adjustment accuracy of the adjustment plate 10 is improved by setting the gear 12 and the rack 11.

[0028] In some embodiments, the adjustment assembly further includes a rotating handle 13, a worm gear 14 and a worm gear 15. The rotating handle 13 is rotatably connected to the workbench 1. The rotating handle 13 is connected to the worm gear 15 to drive the worm gear 15 to rotate. The worm gear 14 is connected to the gear 12 via the third rotating shaft 8. The worm gear 14 is meshed with the worm gear 15. Specifically, Figure 4 and Figure 5 As shown, the handle 13 is rotated, the handle 13 rotates to drive the worm 15 to rotate, the worm 15 rotates to drive the turbine 14 to rotate, and the turbine 14 rotates to drive the gear 12 to rotate. Since the worm 15 has a self-locking effect, the position of the adjustment plate 10 remains fixed after the position adjustment of the adjustment plate 10 is completed, that is, the position of the adjustment plate 10 can be adjusted only when the handle 13 is rotated, so that the adjustment of the adjustment plate 10 is convenient.

[0029] In some embodiments, Figure 1 and Figure 2As shown, the steel pipe grinding machine 100 of the embodiment of the utility model further includes a plurality of support seats 16, which are arranged at intervals along the axial direction of the first rotating shaft 2, the first rotating shaft 2 is rotatably connected to each support seat 16, and at least one support cylinder 4 is provided between two adjacent support seats 16. It can be understood that, since the length of the steel pipe 200 to be polished is relatively long, the length of the first rotating shaft 2 is also set relatively long to effectively support the steel pipe 200 to be polished, and by providing a plurality of support seats 16 to support the first rotating shaft 2, it is beneficial to improve the force stability of the first rotating shaft 2, and avoid deformation due to excessive length, which affects its reliability and service life.

[0030] Alternatively, if Figure 3 As shown, the grinding wheel 6 is connected to the workbench 1 through the fourth rotating shaft 17, and the first motor 3 is transmission-connected to the fourth rotating shaft 17 through a pair of gears 12.

[0031] Optionally, there are multiple grinding wheels 6, which are arranged at intervals along the axial direction of the fourth rotating shaft 17. By setting multiple grinding wheels 6, each part of the steel pipe 200 to be polished can be polished multiple times by multiple grinding wheels 6, which is beneficial to improving the grinding effect.

[0032] In some embodiments, the steel pipe grinder 100 of the embodiment of the utility model further includes a dust cover 18, the dust cover 18 is provided on the grinding wheel 6, and the dust cover 18 has a first through hole and a second through hole arranged oppositely in the length direction of the first rotating shaft 2, and the first through hole and the second through hole are provided for the steel pipe 200 to be grinded to pass through. It can be understood that there is a lot of dust when grinding the steel pipe 200 to be grinded at the grinding site. By providing the dust cover 18, it can be prevented that the dust generated by the grinding is flying, which causes occupational health hazards to the on-site work.

[0033] Optionally, the dust cover 18 is detachably connected to the workbench 1, so that it is convenient to remove the dust cover 18 to repair and install the grinding wheel 6.
