[0018] Beneficial Effects

[0019] The present invention provides a cleaning device for welding surface and a method for using the same. Compared with the prior art, the cleaning device has the following advantages:

[0020] (1) Through the setting of the automatic scraping mechanism for welding slag, the automatic reciprocating scraping treatment of pollutants such as oxides, welding slag, and oil stains at the pipeline welding point is realized. The welding slag and other pollutants can be scraped from the welding point to one side, and then combined with the rapid cleaning component, the automatic rapid cleaning treatment of the welding slag is realized. The timely and rapid scraping and cleaning of the welding slag not only avoids the problem of the welding slag being difficult to remove after cooling, but also improves the strength and sealing of the welding point. There is no need for manual scraping, the degree of automation is high, and the cleaning efficiency is greatly improved. At the same time, through the setting of the vertical pole, vertical pipe, circular plate, and spring, the cleaning scraper is adaptively in close contact with the pipeline surface, which improves the scraping and cleaning effect.

[0021] (2) Through the setting of the swing cleaning unit, the automatic scraping mechanism for welding slag and the quick cleaning component are linked together.

[0044] By setting the swing cleaning unit 8, the three are linked with the automatic scraping mechanism 5 and the quick cleaning component 7. While scraping the welding slag, it can simultaneously swing and spray water to cool down the welding area due to the friction increase during reciprocating scraping. The up and down swing of the swing rod 88 is used to spray water at multiple angles for cooling, thereby increasing the cooling area. At the same time, the cooled water can automatically wash some fine dust on the pipe and drop it into the collection box 3, so that the welding area is cleaner after cleaning.

[0051] Step 3: When the rotating wheel 53 rotates, the second pulley 715 and the second belt 716 are set to synchronously drive the rotating roller 72 to rotate, and then the rotating roller 72 drives the U-shaped frame 74 to move back and forth through the rotation of the wave groove 73. At this time, the bottom end of the cleaning scraper 711 contacts the surface of the pipeline, and as the cleaning scraper 711 moves back and forth, the welding slag accumulated on the top of the pipeline after scraping is scraped off and cleaned, so that the welding slag falls into the collection box 3 for collection;

Two cylinders (98) are arranged on one side of the vertical plate (91), and the output ends and bottoms of the two cylinders (98) are fixed to the connecting ears (97). The horizontal plate (2) is fixed between the opposite sides of the two vertical plates (91).

8. A method for using a cleaning device for a welding surface, characterized in that: The specific steps include: Step 1: Place the entire device on one side of the welding part of the pipeline, start the four cylinders (98), and make the cylinders (98) contract to drive the two I-shaped blocks (93) to move towards each other, and then the two I-shaped blocks (93) drive the two clamping plates (94) to move towards each other, and then use the two sets of clamping components (9) to clamp the pipeline; Step 2: Start the motor (64), so that the motor (64) drives the rotating wheel (53) and the cam (54) to rotate, and then the cam (54) contacts and squeezes the roller (59), so that the slider (57) moves horizontally back and forth in the slide groove (56), and at the same time squeezes the spring 1 (58), and at the same time the slider (57) drives the cross bar (510) to move horizontally back and forth, and then start the electric push rod (511), so that the electric push rod (511) drives the scraper (512) to move downward, so that the scraper (512) contacts the surface of the pipe (), and moves horizontally back and forth under the drive of the cross bar (510), scrapes off the welding slag at the welding place and pushes the welding slag to one side; Step 3: While the rotating wheel (53) is rotating, the second pulley (715) and the second belt (716) are arranged to synchronously drive the rotating roller (72) to rotate, and then the rotating roller (72) drives the U-shaped frame (74) to move back and forth through the rotation of the wave groove (73). At this time, the bottom end of the cleaning scraper (711) contacts the surface of the pipeline, and as the cleaning scraper (711) moves back and forth, the welding slag accumulated on the top of the pipeline after scraping is scraped off and cleaned, so that the welding slag falls into the collection box (3) for collection; Step 4: As the rotating wheel (53) rotates, the rotating wheel (53) drives the rotating arm 1 (81) and the rotating arm 2 (87) to rotate, and the rotating arm 2 (87) drives the L-shaped frame (85), the shaft sleeve (84) and the swing rod (88) to swing up and down and back and forth. At the same time, the spray head (811) is started, and the spray head (811) sprays clean water to clean and cool the welding position, and the cleaned water falls into the collection box (3) for collection.
