[0027] Example 1:

[0028] The utility model provides a device for cleaning pipeline welding slag.

[0029] In one embodiment of the present utility model, a cleaning device for pipeline welding slag includes a workbench 1 and a linear moving device 2 and a clamp 3 respectively arranged at both ends of the workbench 1, and also includes a driving member 4, a telescopic frame 5, a grinding head 6 and a cleaning assembly 7. The driving member 4 is arranged on the linear moving device 2, and the power output end of the driving member 4 is detachably connected to the telescopic frame 5 through an extension rod 8. The grinding head 6 and the cleaning assembly 7 are provided on the telescopic frame 5. The telescopic frame 5 is used to drive the grinding head 6 and the cleaning assembly 7 to move relative to the driving member 4 in a direction away from or close to the extension rod 8. The grinding head 6 and the cleaning assembly 7 are used for grinding the weld and cleaning the welding slag, respectively.

[0030] Specifically, if Figures 1 to 3As shown, in the present invention, a device for cleaning pipe welding slag, a workbench 1 can provide a stable support structure to ensure the stable operation of the present invention; at the same time, since a linear motion device 2 and a clamp 3 are respectively provided at both ends of the workbench 1, the clamp 3 is used to clamp the welded steel pipe, so that the steel pipe can be firmly placed on the workbench 1, thereby facilitating the grinding of the weld seam of the steel pipe and cleaning the welding slag. Furthermore, since the driving member 4 is provided on the linear motion device 2, and the power output end of the driving member 4 is detachably connected to the telescopic frame 5 through the extension rod 8, and the driving member 4 can be adopted as a motor in the prior art, that is, the two ends of the extension rod 8 are detachably connected to the output shaft of the driving member 4 and the telescopic frame 5, and the detachable connection method can be adopted as a threaded connection, thereby not only facilitating the disassembly and assembly of the extension rod 8 and the telescopic frame 5 and facilitating maintenance, but also enabling the telescopic frame 5 to rotate synchronously with the output shaft of the driving member 4 under the transmission of the extension rod 8, the structural design is simple and reasonable.

[0031] When the tool 5 is moved to the left, the grinding head 6 and the cleaning assembly 7 are moved to the right, so that the tool 5 can be moved to the left and right sides of the tool 5. When the tool 5 is moved to the right, the grinding head 6 and the cleaning assembly 7 are moved to the right, so that the tool 5 can be moved to the left, and the grinding head 6 and the cleaning assembly 7 are moved to the right, so that the tool 5 can be moved to the right, so that the tool 5 can be moved to the right,

[0032] It is obvious that the cleaning device for pipeline welding slag of the present invention can adjust the telescopic amount of the telescopic frame 5 according to the actual diameter of the steel pipe, and thereby enable the grinding head 6 to grind the welds of steel pipes of different diameters. Compared with the prior art, the present invention does not need to repeatedly replace the grinding head 6, and only needs to simply adjust the telescopic frame 5. It is not only highly applicable, but also simplifies the operating steps, making it simpler, more flexible and convenient to use. It also shortens the operating time of the staff and reduces the labor intensity, improves work efficiency, and does not need to make grinding heads 6 of various specifications to grind the welds at different steel pipes, saving processing costs. In addition, the present invention can also synchronously clean the ground-off welding slag and other impurities through the cleaning component 7, thereby effectively preventing the welding slag and other impurities from adhering and accumulating in the steel pipe during subsequent use, keeping the inside of the steel pipe clean and smooth, and reducing the probability of blockage in the steel pipe.

[0033] In one embodiment, the extension rod 8 is hollow, and the telescopic frame 5 includes an adjusting rod 9, a mounting seat 10, two connecting seats 11 and a plurality of connecting rods 12. The adjusting rod 9 is detachably connected to the extension rod 8. An annular flange 13 is formed on the outer wall of the adjusting rod 9. The two connecting seats 11 are movably arranged on the adjusting rod 9 at intervals. The two ends of the plurality of connecting rods 12 are respectively hinged to the connecting seat 11 and the mounting seat 10. The grinding head 6 and the cleaning assembly 7 are detachably mounted on the mounting seat 10.

[0034] Specifically, if Figures 1 to 3 As shown, since the extension rod 8 is hollow and the adjustment rod 9 is detachably connected to the extension rod 8, the detachable connection can be a threaded connection. This not only facilitates the disassembly, assembly, and replacement of the adjustment rod 9, facilitating maintenance, but also enables the adjustment rod 9 to rotate synchronously with the output shaft of the driving member 4 under the drive of the extension rod 8, resulting in a simple and reasonable structural design. Furthermore, since the annular flange 13 is formed on the outer wall of the adjustment rod 9, it is convenient for workers to tighten the adjustment rod 9 using tools such as a wrench, making operation simple and convenient. It can be understood that when the diameter of the inner wall of the steel pipe to be processed is large, since the two connecting seats 11 are set on the adjusting rod 9 in a limited and movable manner, the adjusting rod 9 and the two connecting seats 11 can be installed in a limited and movable manner by a threaded connection, and the two ends of the connecting rods 12 are respectively hinged to the connecting seat 11 and the mounting seat 10. The staff can screw the adjusting rod 9 into the extension rod 8. At this time, the two connecting seats 11 are close to each other and can drive the mounting seat 10 to move in the direction away from the adjusting rod 9, so that the grinding head 6 and the cleaning assembly 7 on the mounting seat 10 can abut against the inner wall of the steel pipe and grind the weld and clean the welding slag under the action of the driving member 4 and the linear moving device 2; conversely, the staff can screw the adjusting rod 9 to the outside of the extension rod 8. At this time, the two connecting seats 11 are away from each other and can drive the mounting seat 10 to move in the direction close to the adjusting rod 9, which is suitable for processing steel pipes with larger inner wall diameters.

[0035] In one embodiment, specifically, Figure 2 and Figure 3 As shown, a number of mounting seats 10 are movably installed between the two connecting seats 11 through a number of connecting rods 12, and a grinding head 6 and a cleaning assembly 7 are respectively provided on the several mounting seats 10, so that the weld can be ground and cleaned at multiple points, thereby improving the grinding efficiency and effect, and being reliable to use.

[0036] In one embodiment, a limit ring 14 is detachably mounted on one end of the adjusting rod 9 away from the extension rod 8. Specifically, Figure 1 and Figure 3 As shown, the limit ring 14 not only prevents the connecting seat 11 from detaching from the adjusting rod 9 when the staff rotates the adjusting rod 9, but also facilitates the disassembly and replacement of several connecting rods 12 and the connecting seat 11, which is beneficial to assembly and maintenance.

[0037] In one embodiment, two ears 15 are formed at intervals on the side of the plurality of mounting seats 10 away from the adjusting rod 9, and the grinding head 6 is detachably mounted between the two ears 15 through a locking member. Figure 2 and Figure 3 As shown, the locking member can be a bolt connection in the prior art, that is, the screw passes through the grinding head 6 and the two support ears 15 and is threadedly connected to the nut, so that the grinding head 6 can be rotatably installed between the two support ears 15, and then the weld can be ground under the drive of the driving member 4. The structural design is simple and reasonable.

[0038] In one embodiment, the cleaning assembly 7 includes a plurality of rotating seats 16 and a brush 17. The plurality of rotating seats 16 are respectively mounted on the two supporting ears 15 in a limited and movable manner, and a brush 17 is detachably mounted on each of the plurality of rotating seats 16. Specifically, Figure 2 and Figure 3 As shown, the plurality of rotating seats 16 and the two support ears 15 can be mounted in a limited and movable manner using bolts. That is, the plurality of rotating seats 16 are respectively arranged obliquely on the two support ears 15, thereby enabling the plurality of rotating seats 16 to better adapt to the curvature of the inner wall of the pipe and avoid interference. Furthermore, the plurality of brushes 17 can improve the cleaning effect of welding slag, and the use is reliable.

[0039] In one embodiment, a collection box for collecting welding slag is provided between the linear moving device 2 and the clamp 3. Specifically, Figure 1 and Figure 3 As shown, when the linear moving device 2 retracts, the welding slag and other impurities can be swept out of the steel pipe by a number of brushes 17. At this time, the welding slag and other impurities automatically fall into the collection box, thereby completing the collection of the welding slag and other impurities, and preventing the welding slag and other impurities from being scattered at will, causing the workbench 1 to be dirty and affecting the operation of the staff.

[0040] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
