Description

Technical Field

[0001] This invention relates to the field of welding cleaning technology, specifically to a cleaning device for welding surfaces and its usage method. Background Technology

[0002] Pipeline joint welding is a crucial step in pipeline engineering, and its quality directly affects the safety and service life of the pipeline system. However, if contaminants such as oxides, welding slag, and oil generated during the welding process are not cleaned up in a timely manner, they will seriously affect the strength and sealing of the welded joint.

[0003] Traditional cleaning methods, such as manual grinding and wire brush cleaning, are not only inefficient and difficult to guarantee consistent cleaning quality, but also pose safety hazards. In addition, during the grinding and cleaning process, some fine welding slag and dust are difficult to remove completely. Moreover, the friction during grinding and cleaning can cause the temperature to rise, which may cause the already loosened welding slag to remelt or soften, making it even more difficult to remove completely during the grinding process. To address these issues, we propose a cleaning device for welded surfaces and its usage method. Summary of the Invention

[0013] The present invention also discloses a method of using a cleaning device for welding surfaces, specifically including the following steps:

[0014] Step 1: Place the entire device on one side of the welded part of the pipe, start the four cylinders, and make the cylinders contract to drive the two I-shaped blocks to move in opposite directions. Then the two I-shaped blocks drive the two clamping plates to move in opposite directions, and then use the two sets of clamping components to clamp the pipe.

[0015] Step 2: Start the motor to drive the rotating wheel and cam to rotate. The cam then contacts and squeezes the roller, causing the slider to move horizontally back and forth in the groove. At the same time, it squeezes the spring and the slider drives the crossbar to move horizontally back and forth. Then, the electric push rod is activated, which drives the scraper to move downward, so that the scraper contacts the surface of the pipe and moves horizontally back and forth under the action of the crossbar, scraping off the weld slag at the weld and pushing the weld slag to one side.

[0016] Step 3: While the rotating wheel is rotating, the rotating roller is driven to rotate synchronously through the setting of pulley 2 and belt 2. Then, when the rotating roller rotates, the U-shaped frame moves back and forth through the rotation of the wave groove. At this time, the bottom end of the cleaning scraper contacts the surface of the pipe. As the cleaning scraper moves back and forth, the welding slag accumulated on the top of the pipe is scraped off and cleaned, so that the welding slag falls into the collection box for collection.

[0017] Step 4: As the rotating wheel rotates, it drives rotating arm 1 and rotating arm 2 to rotate. Rotating arm 2 drives the L-shaped frame, bushing and swing rod to swing up and down. At the same time, the nozzle is activated and sprays clean water to clean and cool the welded area. The cleaned water falls into the collection box for collection.

[0018] Beneficial effects

[0019] This invention provides a cleaning device for welded surfaces and a method for using the same. Compared with the prior art, it has the following advantages:

[0020] (1) By setting up an automatic slag scraping mechanism, the automatic reciprocating scraping of contaminants such as oxides, slag, and oil at the pipe welding joint is realized. The slag and other contaminants can be scraped from the welding joint to one side. With the help of the quick cleaning component, the automatic and quick cleaning of the slag is realized. The timely and quick scraping and cleaning of the slag not only avoids the problem of the slag being difficult to remove after cooling, but also improves the strength and sealing of the welding joint. There is no need for manual scraping. The degree of automation is high and the cleaning efficiency is greatly improved. At the same time, the setting of the upright, the riser, the circular plate, and the second spring makes the cleaning scraper adaptively and closely contact the pipe surface, which improves the scraping and cleaning effect.

[0021] (2) By setting up the swing cleaning unit, it is linked with the automatic slag scraping mechanism and the rapid cleaning component. While scraping the slag, it can simultaneously swing and spray water to cool down the weld joint caused by friction during the reciprocating scraping. By swinging the swing arm up and down, it can spray water at multiple angles to cool down the weld joint and increase the cooling area. At the same time, the cooled water can automatically wash away some fine dust on the pipe and drop it into the collection box, making the weld joint cleaner after cleaning.

[0022] (3) By setting up the clamping components, the device can be adapted to clamp and fix pipes of different sizes, making it convenient to use pipes of different sizes and expanding the applicability of the entire device. Attached Figure Description

[0033] The present invention provides three technical solutions, specifically including the following embodiments:

[0034] Example 1

[0035] Please see Figures 1-7 A cleaning device for welding surfaces includes a base plate 1, a horizontal plate 2 above the base plate 1, a collection box 3 fixed on the top of the base plate 1, the collection box 3 is used to collect scraped oxides, welding slag, oil stains and other contaminants as well as cleaning wastewater, a through hole 4 is opened through the top of the horizontal plate 2, and an automatic welding slag scraping mechanism 5 is provided on the horizontal plate 2 to scrape the welding slag at the welding point. The through hole 4 allows the automatic welding slag scraping mechanism 5 and the swing cleaning unit 8 to be connected as one unit for linkage.

[0036] The automatic slag scraping mechanism 5 includes an L-shaped plate 51 fixed to the top of the horizontal plate 2. A mounting base 52 is fixed to one side of the L-shaped plate 51 for support and fixation. A rotating wheel 53 is rotatably connected to the bottom of the mounting base 52. The top end of the rotating shaft of the rotating wheel 53 passes through the mounting base 52 and extends to the top of the mounting base 52. A cam 54 is fixed on the rotating shaft of the rotating wheel 53. A drive assembly 6 for driving the rotating wheel 53 to rotate is provided on the L-shaped plate 51. A fixing base 55 is fixed to one side of the mounting base 52. A groove 56 is opened on the top of the fixing base 55. A slider 57 is slidably connected to the inner surface of the groove 56. A spring 58 is fixed between one side of the slider 57 and the inner wall of the groove 56. The spring 58 is used to reset the slider 57. The other side of the slider 57 is rotatably connected to the roller 59 via a pin. The side surface of the cam 54 contacts and presses against the side surface of the roller 59. A crossbar 510 is fixed to the top of the slider 57, and an electric push rod 511 is fixed to the bottom of the crossbar 510. The electric push rod 511 is controlled by an external switch and is electrically connected to an external power source. A scraper 512 is fixed to the output end of the electric push rod 511. The scraper 512 is adapted to the size of the pipe. When the scraper 512 moves horizontally left and right, it can scrape off the welding slag at the weld. The electric push rod 511 can drive the scraper 512 to make close contact with the pipe surface, which is beneficial for quickly scraping off the welding slag.

[0037] The drive assembly 6 includes a vertical rod 61 rotatably connected to the top of the L-shaped plate 51. Both the top of the vertical rod 61 and the top of the rotating shaft of the rotating wheel 53 are fixed with pulleys 62. The two pulleys 62 are connected by a belt 63. A motor 64 is fixed to the bottom of the L-shaped plate 51. The motor 64 is controlled by an external switch and electrically connected to an external power source. The motor 64 drives the vertical rod 61 to rotate.

[0038] The top of the horizontal plate 2 is also equipped with a quick-cleaning assembly 7 for sweeping and cleaning the scraped welding slag. The quick-cleaning assembly 7 includes a fixed box 71 fixed to the top of the horizontal plate 2. A rotating roller 72 is rotatably connected between the inner walls of the fixed box 71. The surface of the rotating roller 72 is provided with a wave groove 73. The wave groove 73 is opened around the rotating roller 72 and is interconnected. When the rotating roller 72 rotates, it drives the wave groove 73 to rotate. At this time, the connecting column 75 slides in the wave groove 73, thereby driving the U-shaped frame 74 to move back and forth. The fixed box 71 A U-shaped frame 74 is slidably connected to one side, and one side of the U-shaped frame 74 extends into the interior of the fixed box 71. Connecting columns 75 are fixed on opposite sides of the U-shaped frame 74. Both connecting columns 75 slide in the wave groove 73. A square plate 76 is fixed to one side of the U-shaped frame 74. A vertical pole 77 is fixed to the bottom of the square plate 76. A vertical tube 78 is provided at the bottom end of the vertical pole 77. The bottom end of the vertical pole 77 extends into the interior of the vertical tube 78. The outer surface of the vertical pole 77 is slidably connected to the inner surface of the vertical tube 78. A circular plate 79 is fixed to the bottom end of the vertical pole 77.

[0039] A second spring 710 is fixed between the bottom of the circular plate 79 and the bottom wall of the riser 78. A cleaning scraper 711 is fixed at the bottom end of the riser 78. The cleaning scraper 711 can move back and forth. When the scraper blade 512 moves left and right to scrape off the welding slag, it will not interfere with the back and forth movement of the scraper blade 512. When the scraper blade 512 moves to the leftmost position, it just contacts the right side of the cleaning scraper 711. With the setting of the second spring 710, the cleaning scraper 711 can be pressed against the surface of the pipe. A bevel gear 712 is fixed at one end of the rotating roller 72. A rotating rod 713 is rotatably connected to the top of the horizontal plate 2. A second bevel gear 714 is fixed on the outer surface of the rotating rod 713. The first bevel gear 712 meshes with the second bevel gear 714. A second pulley 715 is fixed at the top of the rotating rod 713 and the top of the rotating shaft of the rotating wheel 53. The two pulleys 715 are connected by a belt 716.

[0040] The automatic slag removal mechanism 5 enables automated reciprocating scraping of contaminants such as oxides, slag, and oil at the pipe weld joint. It can scrape contaminants such as slag from the weld joint to one side. Combined with the rapid cleaning component 7, it achieves automated and rapid cleaning of slag. The timely and rapid scraping and cleaning of slag not only avoids the problem of slag being difficult to remove after cooling, but also improves the strength and sealing of the weld joint. It eliminates the need for manual scraping, has a high degree of automation, and greatly improves cleaning efficiency. At the same time, the setting of the upright 77, riser 78, circular plate 79, and spring 710 ensures that the cleaning scraper 711 adapts to close contact with the pipe surface, improving the scraping and cleaning effect.

[0041] Example 2

[0042] Based on Example 1, see Figure 3 , Figure 4 , Figure 8 As shown, a swing cleaning unit 8 for cleaning the welding surface is provided below the horizontal plate 2.

A movable shaft 83 is rotatably connected between the opposite sides of the two L-shaped seats 82. A bushing 84 is fixed to the outer surface of the movable shaft 83. An L-shaped frame 85 is fixed to one side of the bushing 84.

[0043] A counterweight 86 is fixed to one side of the L-shaped frame 85. A second rotating arm 87 is rotatably connected to the counterweight 86. The top of the second rotating arm 87 is rotatably connected to the bottom of one side of the rotating arm via a pin. A swing rod 88 is fixed to the other side of the bushing 84. When the rotating wheel 53 rotates, it can drive the swing rod 88 to swing up and down repeatedly. A water tank 89 is fixed to one end of the swing rod 88. The water tank 89 is filled with clean water. Multiple water outlet pipes 810 are connected to one side of the water tank 89. One end of each of the multiple water outlet pipes 810 is connected to a nozzle 811. The nozzle 811 is controlled by an external switch and is electrically connected to an external power supply. After starting, it can spray clean water. A liquid hopper 812 is connected to the top of the water tank 89. Clean water is added to the water tank 89 from the liquid hopper 812.

[0044] By setting up the swing cleaning unit 8, it is linked with the welding slag automatic scraping mechanism 5 and the rapid cleaning component 7. While scraping the welding slag, it can simultaneously swing and spray water to cool down the welding area caused by friction during the reciprocating scraping. By swinging the swing arm 88 up and down, water is sprayed at multiple angles to cool down the area and increase the cooling area. At the same time, the cooled water can automatically wash away some fine dust on the pipes and make it fall into the collection box 3, making the welding area cleaner after cleaning.

[0045] Both sides of the top of the base plate 1 are provided with clamping components 9 that clamp one side of the welding pipe. The clamping components 9 include a vertical plate 91 fixed to the top of the base plate 1. Two vertical grooves 92 are opened through one side of the vertical plate 91. I-shaped blocks 93 are slidably connected to the inner surfaces of the two vertical grooves 92. The dimensions of the I-shaped blocks 93 are adapted to the vertical grooves 92. Clamping plates 94 are fixed to one side of the two I-shaped blocks 93. A rhomboid block 95 is rotatably connected to the other side of the vertical plate 91. Two L-shaped arms 96 are rotatably connected to one side of the rhomboid block 95 through a pin. The far ends of the two L-shaped arms 96 are rotatably connected to one side of the I-shaped block 93. Connecting ears 97 are fixed to the other side of the two I-shaped blocks 93. Two cylinders 98 are provided on one side of the vertical plate 91. The output end and bottom of the two cylinders 98 are fixed to the connecting ears 97. A horizontal plate 2 is fixed between the opposite sides of the two vertical plates 91. The four cylinders 98 are controlled by the same external switch and are electrically connected to an external power source.

[0046] The clamping component 9 enables adaptive clamping and fixing of pipes of different sizes, facilitating the use of pipes of different sizes and expanding the applicability of the entire device.

[0047] Example 3

[0048] Based on Example 2, see Figures 1-8 As shown, this invention discloses a method for using a cleaning device for welding surfaces, specifically including the following steps:

[0049] Step 1: Place the entire device on one side of the welded part of the pipe, start the four cylinders 98, so that the cylinders 98 contract and drive the two I-shaped blocks 93 to move in opposite directions, and then the two I-shaped blocks 93 drive the two clamping plates 94 to move in opposite directions, and then use the two sets of clamping components 9 to clamp the pipe.

[0050] Step 2: Start the motor 64, which drives the rotating wheel 53 and the cam 54 to rotate. Then, the cam 54 contacts and squeezes the roller 59, causing the slider 57 to move horizontally back and forth in the groove 56. At the same time, it squeezes the spring 58. Simultaneously, the slider 57 drives the crossbar 510 to move horizontally back and forth, which in turn starts the electric push rod 511. 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 crossbar 510, scraping off the welding slag at the weld and pushing the welding slag to one side.

[0051] Step 3: As the rotating wheel 53 rotates, the rotating roller 72 is driven to rotate synchronously through the setting of the second pulley 715 and the second belt 716. Then, when the rotating roller 72 rotates, the U-shaped frame 74 moves 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 pipe. As the cleaning scraper 711 moves back and forth, the welding slag accumulated on the top of the pipe is scraped off and cleaned, so that the welding slag falls into the collection box 3 for collection.

[0052] 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. The rotating arm 2 87 drives the L-shaped frame 85, the bushing 84 and the swing rod 88 to swing up and down. At the same time, the nozzle 811 is activated and sprays clean water to clean and cool the welded area. The cleaned water falls into the collection box 3 for collection.

[0053] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0054] The embodiments of the invention have been described in detail above, but the content described is only a preferred embodiment of the invention and should not be considered as limiting the scope of the invention. All equivalent changes and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.

6. A cleaning device for welding surfaces according to claim 5, characterized in that: One end of each of the multiple water outlet pipes (810) is connected to a nozzle (811), and the top of the water tank (89) is connected to a liquid hopper (812). Clamping assemblies (9) clamping one side of the welded pipe are provided on both sides of the top of the base plate (1). Each clamping assembly (9) includes a vertical plate (91) fixed to the top of the base plate (1). Two vertical grooves (92) are opened through one side of the vertical plate (91). I-shaped blocks (93) are slidably connected to the inner surfaces of the two vertical grooves (92). Clamping plates (94) are fixed to one side of each of the two I-shaped blocks (93). A rhombus-shaped block (95) is rotatably connected to the other side of the vertical plate (91). Two L-shaped arms (96) are rotatably connected to one side of the rhombus-shaped block (95) via a pin. The ends of the two L-shaped arms (96) that are far apart are rotatably connected to one side of the I-shaped block (93). Connecting ears (97) are fixed to the other side of the two I-shaped blocks (93). Two cylinders (98) are provided on one side of the vertical plate (91). The output end and bottom 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).

7. The method of using the cleaning device for welding surfaces according to claim 6, characterized in that: Specifically, the following steps are included: Step 1: Place the entire device on one side of the welded part of the pipe, start the four cylinders (98), so that the cylinders (98) contract and drive the two I-shaped blocks (93) to move in opposite directions, and then the two I-shaped blocks (93) drive the two clamping plates (94) to move in opposite directions, and then use the two sets of clamping components (9) to clamp the pipe. Step 2: Start the motor (64) to drive the rotating wheel (53) and cam (54) to rotate. Then the cam (54) contacts and squeezes the roller (59), causing the slider (57) to move horizontally back and forth in the groove (56) and squeeze the spring (58). At the same time, the slider (57) drives the crossbar (510) to move horizontally back and forth. Then start the electric push rod (511) to drive 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 crossbar (510) to scrape off the welding slag at the welding point and push the welding slag to one side. Step 3: While the rotating wheel (53) is rotating, the rotating roller (72) is driven to rotate synchronously through the setting of the second pulley (715) and the second belt (716). Then, when the rotating roller (72) rotates, the U-shaped frame (74) is driven 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 pipe. As the cleaning scraper (711) moves back and forth, the welding slag accumulated on the top of the pipe 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 one (81) and the rotating arm two (87) to rotate. The rotating arm two (87) drives the L-shaped frame (85), the bushing (84) and the swing rod (88) to swing up and down. At the same time, the nozzle (811) is activated. The nozzle (811) sprays clean water to clean and cool the welded area. The cleaned water falls into the collection box (3) for collection.
