Description

Technical Field

[0001] This invention belongs to the field of welding cleaning technology, and particularly relates to a device and method for cleaning weld deposits on steel structures. Background Technology

[0002] Welding deposits on steel structures refer to various residues and impurities generated during the welding process. These deposits can affect weld quality, structural performance, and appearance. Below are some common welding deposits, their characteristics, and treatment methods: Common weld attachments Weld slag: Solid residue formed during the welding process, usually produced by the reaction of welding materials and shielding gas. Weld slag is generally hard, adheres to the weld surface, and may form oxides.

[0003] Oxides: Metal oxides produced by the high-temperature welding reaction, commonly found on the weld surface. Oxides are usually gray or black and reduce the strength of the weld joint.

[0004] Weld spatter: Small particles formed by molten metal splashing during welding, which usually adhere to the surrounding substrate. Weld spatter is uneven and easily detaches, affecting the appearance and subsequent processing.

[0005] Oil and impurities: Grease, dust, rust, and other impurities on the surface of steel. These impurities can affect the quality of welding and lead to welding defects.

[0006] Unfused zone: The area where the weld and the base metal are not fully fused during welding. It may form tiny pores or cracks, affecting the strength of the structure.

[0007] Cleaning weld deposits is a crucial step in ensuring weld quality and subsequent processing. Common cleaning methods include: Mechanical cleaning: using tools such as wire brushes, grinders, and scrapers to remove weld slag, oxides, and spatter.

[0008] Chemical cleaning: Use chemical cleaning agents (such as pickling agents) to remove oxides and rust. Care should be taken to select appropriate chemicals to prevent damage to the steel.

[0009] Existing technologies disclose several invention patents in the field of welding cleaning technology. Among them, invention patent application number CN202311506566.7 discloses a steel structure welding attachment cleaning device. Through the setting of an alarm control component, it can realize the work of quickly alarming when the cleaning is incomplete. The set of flat detection component detection method is reliable and efficient, ensuring the cleanliness of the weld. It utilizes the fact that oxides and other impurities present in the welding process will have protrusions, and there is a height difference between them and the weld. Once there are protruding impurities, when the hand slides and attaches to the mounting component, the attachment detection attachment attachment head is stuck, and the pressure sensor is squeezed, which can trigger the alarm. This ensures the cleaning effect and can realize the work of quickly and efficiently inspecting the weld after cleaning, ensuring the quality of subsequent painting and other work.

[0010] Existing technologies are suitable for cleaning weld seams on flat surfaces. However, in steel structure welding, two steel plates are often welded at right angles. In this case, existing technologies are not convenient for cleaning the weld seam between the two steel plates. Incomplete cleaning can lead to the residue of weld slag, oxides and other attachments, which can affect the welding quality and structural strength.

[0011] Based on this, the present invention designs a device and method for cleaning weld attachments on steel structures to solve the above problems. Summary of the Invention

[0012] The purpose of this invention is to address the problem that existing technologies are suitable for cleaning weld seams on flat surfaces, but in steel structure welding, two steel plates are often welded at right angles. In this case, existing technologies are not convenient for cleaning the weld seam between the two steel plates, resulting in incomplete cleaning and leaving weld slag, oxides, and other attachments, which affect the welding quality and structural strength. Therefore, this invention proposes a steel structure welding attachment cleaning device and method.

[0015] As a further description of the above technical solution: The adjustment mechanism includes a linkage assembly.

A worm gear is fixedly connected to the end of the linkage assembly connected to the handheld base. A worm is meshed and driven on one side of the worm gear, and the worm is rotatably connected to the handheld base.

[0016] As a further description of the above technical solution: A motor A is fixedly connected to the adjusting frame. A pulley A is fixedly connected to the output end of the motor A. A belt is frictionally driven on the pulley A. A pulley B is frictionally driven on the other end of the belt. The pulley B is fixedly connected to the welding slag cleaning wheel. A ring rack is fixedly connected to the inner wall of one end of the adjusting frame.

[0017] As a further description of the above technical solution: A wire brush is fixedly connected to the outer wall of the slag cleaning wheel, and multiple guide heads are fixedly connected to the inner wall of the slag cleaning wheel.

[0018] As a further description of the above technical solution: The welding slag crushing mechanism includes a universal joint A, which is rotatably connected to the inner wall of the welding slag cleaning wheel. A transmission wheel is fixedly connected to the outer end of the universal joint A, and the transmission wheel meshes with a ring rack for transmission. A reciprocating screw is fixedly connected to the inner end of the universal joint A, and a slider is slidably fitted on the outer wall of the reciprocating screw. A crushing sleeve is rotatably connected to the slider, and a spiral groove is formed on the outer wall of the crushing sleeve. The inner wall of the spiral groove is slidably fitted with the outer wall of the guide head.

[0019] As a further description of the above technical solution: An adjusting wheel is fixedly connected to one end of the swing frame that is rotatably connected to the adjusting frame.

[0020] As a further description of the above technical solution: The weld grinding mechanism includes a sliding frame, one end of which is slidably connected to the inner wall of the swing frame, a spring is fixedly connected to the sliding frame, the other end of the spring is fixedly connected to the inner wall of the swing frame, a motor B is fixedly connected to one side of the sliding frame, a drive wheel is fixedly connected to the output end of the motor B, and a grinding roller is fixedly connected to the output end of the motor B through the sliding frame.

[0021] As a further description of the above technical solution: The transmission mechanism includes a universal joint B, which is rotatably connected to the swing frame. A transmission sleeve is fixedly connected to one end of the universal joint B, and a transmission rod is slidably fitted inside the transmission sleeve. The other end of the transmission rod is rotatably connected to the sliding frame. A driven wheel is fixedly connected to the end of the transmission rod connected to the sliding frame, and the driven wheel meshes with the driving wheel for transmission. A rotating rod is fixedly connected to the other end of the universal joint B, and a connecting rod is rotatably connected to the other end of the rotating rod. An adjusting rack is rotatably connected to the other end of the connecting rod, and one end of the adjusting rack is slidably fitted to the swing frame. The adjusting rack meshes with the adjusting wheel for transmission.

[0022] A method for cleaning weld deposits on steel structures includes the following steps: S1. After right-angle welding of the steel structure, place the hand-held base on the steel structure by gripping the handle, and then rotate the worm gear to drive the connecting rod group connected to the worm wheel to rotate, so that the connecting rod group drives the adjusting frame to move, so that the wire brush on the welding slag cleaning wheel can contact the weld. S2. Then, motor A drives pulley A to rotate, which in turn drives the belt to rotate. The belt then drives the slag cleaning wheel connected to pulley B to rotate. Under the action of the ring rack, the transmission wheel rotates, which in turn drives the reciprocating screw connected to universal joint A to rotate. The reciprocating screw drives the slider to move back and forth, which in turn drives the crushing sleeve to move back and forth. Under the action of the guide head, the crushing sleeve with spiral grooves rotates, causing the crushing sleeve to squeeze the slag on the weld. After the slag is broken and loosened, the wire brush on the rotating slag cleaning wheel removes the slag and oxides. S3. Then, under the action of the spring, the grinding roller on the sliding frame will stick to the weld. The motor B drives the connected grinding roller to rotate, so that the grinding roller grinds the cleaned weld, removes the burrs and spatter generated during the welding process, improves the surface smoothness, further removes the surface oxides, and ensures the adhesion of subsequent processing. S4. Simultaneously, motor B drives the driven wheel to rotate via the driving wheel, which in turn drives the transmission rod to rotate, which in turn drives the transmission sleeve to rotate. This causes the universal joint B to rotate, and then the universal joint B drives the connecting rod via the rotating rod, which in turn drives the adjusting rack to move, thereby causing the swing frame connected to the adjusting wheel to swing back and forth, so that the grinding roller can evenly grind the right-angle weld.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, by setting an inclined adjustment frame, the slag cleaning wheel can easily clean the weld seam between two steel plates that are welded at right angles under the drive of the adjustment mechanism, ensuring the effective removal of slag, oxides and spatter. At the same time, under the action of the slag crushing mechanism, the slag on the weld seam can be crushed, making the slag loose and easier to clean, reducing the need for repeated cleaning. This can effectively improve the cleaning efficiency of right angle weld seams in steel structure welding, not only solving the limitations of the prior art, but also improving the safety and convenience of cleaning.

[0024] 2. In this invention, by setting up a weld grinding mechanism, a spring is used to make the grinding roller adhere to the cleaned weld, ensuring uniform pressure during the grinding process. At the same time, the rotating grinding roller can grind the weld, and the weld surface is smooth after grinding, which helps to improve the adhesion and protection effect of subsequent coating or anti-corrosion treatment.

[0025] 3. In this invention, by setting a transmission mechanism, when the grinding roller grinds the weld, the rotating mechanism drives the grinding roller to reciprocate, ensuring that the grinding roller can apply pressure evenly to every part of the right-angle weld, thereby achieving a better grinding effect. Through reciprocating oscillation, the grinding roller can evenly cover the entire surface of the weld, avoiding uneven weld surface caused by uneven local grinding, and further improving the cleaning quality of the weld.

The inner wall of the spiral groove 506 is slidably fitted with the outer wall of the guide head 402. Under the action of the ring rack 205, the transmission wheel 502 will rotate, thereby driving the reciprocating screw 503 connected to the universal joint A501 to rotate. The reciprocating screw 503 will drive the slider 504 to move back and forth, and the slider 504 will drive the crushing sleeve 505 to move back and forth. Under the action of the guide head 402, the crushing sleeve 505 with the spiral groove 506 will rotate, causing the crushing sleeve 505 to squeeze the weld slag on the weld seam, causing the weld slag to break.

[0035] Specifically, such as Figure 8As shown, an adjusting wheel 601 is fixedly connected to one end of the swing frame 6 that is rotatably connected to the adjusting frame 2.

[0036] Specifically, such as Figure 9 As shown, the weld grinding mechanism 7 includes a sliding frame 701.

A motor B703 is fixedly connected to one side of the sliding frame 701. A drive wheel 704 is fixedly connected to the output end of the motor B703. The output end of the motor B703 passes through the sliding frame 701 and is fixedly connected to a grinding roller 705.

[0037] Specifically, such as Figure 8 As shown, the transmission mechanism 8 includes a universal joint B801, which is rotatably connected to the swing frame 6. A transmission sleeve 802 is fixedly connected to one end of the universal joint B801. A transmission rod 803 is slidably fitted inside the transmission sleeve 802. The other end of the transmission rod 803 is rotatably connected to the sliding frame 701.

Motor B703 drives driven wheel 804 to rotate via drive wheel 704, which in turn drives transmission rod 803 to rotate, which in turn drives transmission sleeve 802 to rotate. This causes universal joint B801 to rotate, and then universal joint B801 drives connecting rod 806 via rotating rod 805. This causes connecting rod 806 to move adjusting rack 807, which in turn causes swing frame 6 connected to adjusting wheel 601 to swing back and forth.

[0038] A method for cleaning weld deposits on steel structures includes the following steps: S1. After the steel structure is welded at right angles, the hand-held base 1 is placed on the steel structure by the handle 101. Then, by rotating the worm 303, the worm 303 drives the connecting rod group 301 connected to the worm wheel 302 to rotate, which in turn drives the adjusting frame 2 to move, so that the wire brush 401 on the welding slag cleaning wheel 4 can contact the weld. S2. Then, the motor A201 drives the pulley A202 to rotate, which in turn drives the belt 203 to rotate. At this time, the belt 203 drives the slag cleaning wheel 4 connected to the pulley B204 to rotate. Under the action of the ring rack 205, the transmission wheel 502 rotates, which drives the reciprocating screw 503 connected to the universal joint A501 to rotate. The reciprocating screw 503 drives the slider 504 to move back and forth, which in turn drives the crushing sleeve 505 to move back and forth. Under the action of the guide head 402, the crushing sleeve 505 with the spiral groove 506 rotates, which causes the crushing sleeve 505 to press against the slag on the weld. After the slag is broken and loosened, the wire brush 401 on the rotating slag cleaning wheel 4 removes the slag and oxides. S3. Then, under the action of spring 702, the grinding roller 705 on the sliding frame 701 will stick to the weld. The motor B703 drives the connected grinding roller 705 to rotate, so that the grinding roller 705 grinds the cleaned weld, removes burrs and spatter generated during the welding process, improves the surface flatness, further removes surface oxides, and ensures the adhesion of subsequent processing. S4. Simultaneously, motor B703 drives driven wheel 804 to rotate via drive wheel 704, which in turn drives transmission rod 803 to rotate, which in turn drives transmission sleeve 802 to rotate. This causes universal joint B801 to rotate, and then universal joint B801 drives connecting rod 806 via rotating rod 805. This causes connecting rod 806 to move adjusting rack 807, which in turn causes swing frame 6 connected to adjusting wheel 601 to swing back and forth, so that grinding roller 705 can evenly grind right-angle welds.

[0039] Working principle and usage: After right-angle welding of the steel structure, the hand-held base 1 is placed on the steel structure by the handle 101. Then, by rotating the worm 303, the worm 303 drives the connecting rod group 301 connected to the worm wheel 302 to rotate, which in turn drives the adjusting frame 2 to move, so that the wire brush 401 on the welding slag cleaning wheel 4 can contact the weld. Then, the motor A201 drives the pulley A202 to rotate, which in turn drives the belt 203 to rotate. At this time, the belt 203 drives the slag cleaning wheel 4 connected to the pulley B204 to rotate. Under the action of the ring rack 205, the transmission wheel 502 rotates, which in turn drives the reciprocating screw 503 connected to the universal joint A501 to rotate. The reciprocating screw 503 drives the slider 504 to move back and forth, which in turn drives the crushing sleeve 505 to move back and forth. Under the action of the guide head 402, the crushing sleeve 505 with the spiral groove 506 rotates, which causes the crushing sleeve 505 to press against the slag on the weld. After the slag is broken and loosened, the wire brush 401 on the rotating slag cleaning wheel 4 removes the slag and oxides. Then, under the action of spring 702, the grinding roller 705 on the sliding frame 701 will stick to the weld. The motor B703 drives the connected grinding roller 705 to rotate, so that the grinding roller 705 grinds the cleaned weld, removes burrs and spatter generated during the welding process, improves the surface flatness, further removes surface oxides, and ensures the adhesion of subsequent processing. Simultaneously, motor B703 drives driven wheel 804 to rotate via drive wheel 704, which in turn drives transmission rod 803 to rotate, which in turn drives transmission sleeve 802 to rotate. This causes universal joint B801 to rotate, and then universal joint B801 drives connecting rod 806 via rotating rod 805. This causes connecting rod 806 to move adjusting rack 807, which in turn causes swing frame 6 connected to adjusting wheel 601 to swing back and forth, allowing grinding roller 705 to grind right-angle welds evenly.

10. A cleaning method for a steel structure welding attachment cleaning device according to any one of claims 1-9, characterized in that: Includes the following steps: S1. After the steel structure is welded at right angles, the hand-held base (1) is placed on the steel structure by the handle (101). Then, by rotating the worm (303), the worm (303) drives the connecting rod group (301) connected to the worm wheel (302) to rotate, so that the connecting rod group (301) drives the adjusting frame (2) to move, so that the wire brush (401) on the slag cleaning wheel (4) can contact the weld. S2. Then, the motor A (201) drives the pulley A (202) to rotate, which in turn drives the belt (203) to rotate. At this time, the belt (203) will drive the welding slag cleaning wheel (4) connected to the pulley B (204) to rotate. Under the action of the ring rack (205), the transmission wheel (502) will rotate, thereby driving the reciprocating screw (503) connected to the universal joint A (501) to rotate, so that the reciprocating screw (503) will rotate. 503) will drive the slider (504) to reciprocate, so that the slider (504) will drive the crushing sleeve (505) to reciprocate. Under the action of the guide head (402), the crushing sleeve (505) with the spiral groove (506) will rotate, so that the crushing sleeve (505) will squeeze the welding slag on the weld seam, so that the welding slag will break and loosen, and the wire brush (401) on the rotating welding slag cleaning wheel (4) will remove the welding slag and oxides. S3. Then, under the action of the spring (702), the grinding roller (705) on the sliding frame (701) will stick to the weld. The motor B (703) drives the connected grinding roller (705) to rotate, so that the grinding roller (705) grinds the cleaned weld, removes the burrs and spatter generated during the welding process, improves the surface flatness, further removes the surface oxides, and ensures the adhesion of subsequent processing. S4. At the same time, motor B (703) will drive the driven wheel (804) to rotate through the driving wheel (704), so that the driven wheel (804) drives the transmission rod (803) to rotate, so that the transmission rod (803) drives the transmission sleeve (802) to rotate. At this time, it will drive the universal joint B (801) to rotate. Then the universal joint B (801) will drive the connecting rod (806) through the rotating rod (805), so that the connecting rod (806) drives the adjusting rack (807) to move, so that the swing frame (6) connected to the adjusting wheel (601) will swing back and forth, so that the grinding roller (705) can grind the right angle weld evenly.
