[0021] Specifically, the limiting member includes a connecting plate 2 provided on the side of the protective baffle 10, a height adjustment bolt 201 is threadedly inserted and connected to the bottom of the connecting plate 2, a concave support block 202 is provided on the top of the height adjustment bolt 201 and located on the top of the connecting plate 2, a telescopic bolt 204 is provided on the side of the concave support block 202, and a clamping block 203 is provided at the end of the telescopic bolt 204 and located on the top of the concave support block 202;

[0022] It should be noted that the connecting plate 2 and the protective baffle 10 are fixed by welding. A threaded hole for inserting the height adjustment bolt 201 is provided on the top of the connecting plate 2, and a cylindrical hole for inserting the height adjustment bolt 201 is provided at the bottom of the concave support block 202. The bottom protrusion of the cylindrical hole is inserted into the top side of the height adjustment bolt 201, so that during the rotation of the height adjustment bolt 201, the concave support block 202 does not rotate accordingly. A threaded through hole for inserting the telescopic bolt 204 is provided on the side of the concave support block 202, and the end of the telescopic bolt 204 is rotatably connected with the side of the clamping block 203.

[0023] Specifically, the user rotates the height adjustment bolt 201, which drives the concave support block 202 to adjust the height in the vertical direction, so that the concave support blocks 202 on both sides of the protective baffle 10 support and limit the bottom of the steel pipe. The user rotates the telescopic bolt 204 to limit the horizontal direction of the steel pipe.

[0024] A cleaning member is provided on the top of the grinding machine body 1 and beside the grinding wheel;

[0025] The cleaning member includes a fixed base 3 provided on the top of the grinder body 1, a threaded sleeve 401 is inserted and connected to the top of the fixed base 3, a limiting ring block 4 is provided on the top of the threaded sleeve 401, a cleaning cloth 5 is provided on the inner wall of the limiting ring block 4, and a threaded rod 8 is inserted and connected to the interior of the threaded sleeve 401;

[0026] It should be noted that the fixing seat 3 and the grinding machine body 1 are fixed by welding, the threaded sleeve 401 and the limiting ring block 4 are fixed by welding, the cleaning cloth 5 is designed in an annular shape, and the cleaning cloth 5 and the limiting ring block 4 are bonded with glue. During the grinding process of the scaffolding steel pipe, the steel pipe rotates due to the influence of the grinding wheel, so that the cleaning cloth 5 wipes the surface of the steel pipe to be ground. At the same time, the limiting ring block 4 can limit the vertical direction of the steel pipe, and the cleaning cloth 5 can be adjusted to squeeze and wipe the surface of the steel pipe.

[0027] The bottom of the threaded rod 8 is provided with a rotating portion;

[0028] Specifically, the rotating part includes a worm wheel 7, the bottom end of the threaded rod 8 is inserted and connected to the middle part of the worm wheel 7, and the side of the worm wheel 7 is meshed with a worm 6.

The end of the worm 6 away from the worm wheel 7 is inserted and connected to the inner wall of the movable groove 302. A limiting ring column 602 is provided at the insertion point between the worm 6 and the inner wall of the movable groove 302;

[0029] It should be noted that the lifting groove 301 is a square groove, and the threaded sleeve 401 is also square, so as to prevent the threaded sleeve 401 from rotating as the threaded rod 8 rotates. A cylindrical hole for the worm 6 to be inserted is provided on the side of the movable groove 302, and the limiting ring column 602 is bonded to the inner wall of the cylindrical hole by glue. The end of the worm 6 away from the worm wheel 7 is fixedly connected with a hexagonal threaded groove block 601, which is convenient for the user to insert a tool to rotate the worm 6. The cross-sectional diameter of the end of the worm 6 away from the worm wheel 7 is larger than the diameter of the other end, and the cross-sectional inner diameter of the limiting ring column 602 is smaller than the cross-sectional diameter of the other end of the worm 6, and the other end of the worm 6 is inserted into the inner wall of the movable groove 302, and the limiting ring column 602 jointly limits the position of the worm 6. The connection between the worm 6 and the worm wheel 7 is provided with a thread, and the rest of the parts are not threaded.

[0030] Specifically, the bottom of the threaded rod 8 is connected to the bottom inner wall of the movable groove 302, and a bearing 9 is provided at the intersection of the threaded rod 8 and the bottom inner wall of the movable groove 302. The middle part of the bearing 9 is welded and fixed to the outer side of the threaded rod 8. A groove for the bearing 9 to be inserted is provided at the bottom of the fixed seat 3. The groove wall and the bearing 9 are fixed by welding, thereby limiting the position of the threaded rod 8.

[0031] During actual use, the operator inserts the scaffolding steel pipe from the concave support block 202 with the height adjusted, drives the threaded rod 8 in the inner cavity of the threaded sleeve 401 to rotate from the rotating part in the cleaning component, and then drives the threaded sleeve 401 to move up and insert it from the movable hole 11. The rotating worm 6 causes the worm gear 7 to rotate accordingly, and the threaded rod 8 rotates, so that the limiting ring block 4 moves by means of the threaded sleeve 401 that is raised and lowered by the thread, and then inserts the steel pipe from the middle of the cleaning cloth 5 and enters the top of another concave support block 202. During the grinding process of the steel pipe, the cleaning cloth 5 on the inner wall of the limiting ring block 4 is used to wipe away dust and loose dirt on the surface of the steel pipe to be ground, so as to avoid impurities being pressed into the steel pipe surface by the grinding wheel during the subsequent grinding process of the scaffolding steel pipe, causing secondary pollution, and affecting the subsequent coating of the steel pipe and the welding of the clamping joint.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
