Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a welding H-beam fillet weld cleaning device of the present invention includes a first screw 1, with first mounting plates 2 at both ends of the first screw 1. The first mounting plates 2 are equipped with a traveling wheel 3, a drive mechanism for driving the traveling wheel 3, a lateral limiting mechanism for preventing the traveling wheel 3 from detaching from the flange plate 2701 of the welded H-beam 27, and a grinder 16. The number of first screws 1 is one or two, and the corresponding number of first mounting plates 2 is two or four. The drive mechanism drives the traveling wheel 3 to rotate via a motor and gear meshing method or a motor and belt / pulley method. The lateral limiting mechanism is located on the outside of the flange plate 2701 corresponding to the welded H-beam 27. The welded H-beam fillet weld cleaning device is assembled on the welded H-beam. The two flange plates 2701 of the welded H-beam 27 are located between the two lateral limiting mechanisms to prevent the welded H-beam fillet weld cleaning device from falling off the welded H-beam 27 during the movement along the length of the welded H-beam 27. The lateral limiting mechanism is a roller rotatably installed at the lower end of the second screw 4 or a roller 5 rotatably installed at the lower end of the second screw 4.

[0021] A welding H-beam fillet weld cleaning device based on the above structure involves placing a first screw 1 laterally on the welding H-beam 27. Two traveling wheels 3 on two first mounting plates 2 are centrally positioned on the top surfaces of the corresponding flange plates 2701 of the welding H-beam 27. The grinding head 21 of the grinder 16 contacts the fillet weld of the welding H-beam 27. The two flange plates 2701 of the welding H-beam 27 are clamped between two lateral limiting mechanisms on the two first mounting plates 2, causing the traveling wheels 3 to move between the corresponding flange plates 2701 of the welding H-beam 27. The flange plate 2701 moves forward to prevent the H-beam fillet weld cleaning device from falling off the welded H-beam 27. The grinder 16 starts working to grind and remove the fillet weld of the welded H-beam 27. The drive mechanism starts working, driving the two traveling wheels 3 to move along the length of the welded H-beam 27 on the two corresponding flange plates 2701, thus moving the H-beam fillet weld cleaning device from one end of the welded H-beam 27 to the other end, completing the cleaning process. Remove the slag from the fillet weld on one side of the welded H-beam 27; stop the grinder 16 and drive motor, and remove the fillet weld cleaning device; flip the welded H-beam 27 so that the fillet weld on the other side faces upward; install the fillet weld cleaning device on the welded H-beam 27, with the two wheels 3 centered on the top surface of the other end of the two corresponding flange plates 2701 of the welded H-beam 27; start the grinder 16 to grind and remove the fillet weld on the other side of the welded H-beam 27; and start the drive mechanism. When the machine starts working, the drive mechanism drives the two traveling wheels 3 to move along the length of the welded H-beam 27 on the two corresponding flange plates 2701 of the welded H-beam 27, which in turn moves the welded H-beam fillet weld cleaning device from one end of the welded H-beam 27 to the other end, completing the removal of weld slag from the fillet weld on the other side of the welded H-beam 27. The grinder 16 and the drive motor stop working, and the welded H-beam fillet weld cleaning device is removed, completing the removal of weld slag from the fillet weld of the welded H-beam 27. The welding H-beam fillet weld cleaning device of this application automatically and quickly grinds and removes the fillet welds of the welding H-beams, improving the grinding and cleaning efficiency of the fillet welds of the welding H-beams, reducing the labor intensity of workers, and avoiding the harm to workers' health caused by dust generated by manual cleaning. The drive mechanism drives the walking wheels 3 to move at a uniform speed, driving the grinder 16 to uniformly grind and remove the fillet welds of the welding H-beams, improving the grinding and cleaning quality of the fillet welds of the welding H-beams, and improving the reliability of weld quality. It is particularly suitable for grinding and cleaning the fillet welds of the welding H-beams.

[0022] As one possible implementation method, such as Figure 2 , Figure 4As shown, the lateral limiting mechanism includes a second screw 4, the first mounting plate 2 is provided with an elongated hole 201, the elongated hole 201 is provided along the axial direction of the first screw 1, the upper end of the second screw 4 is provided with two first locking nuts 6, the upper end of the second screw 4 passes through the elongated hole 201, the first mounting plate 2 is located between the two first locking nuts 6, and the lower end of the second screw 4 is rotatably provided with a roller 5, the roller 5 is coaxial with the second screw 4.

[0023] Loosen the first locking nut 6, move and adjust the corresponding second screw 4 along the elongated hole (201) of the corresponding first mounting plate 2, and then adjust the distance between the corresponding roller 5 and the flange plate 2701 corresponding to the welded H-beam 27, so that each roller 5 is in close contact with the outer wall of the flange plate 2701 corresponding to the welded H-beam 27. Tighten the first locking nut 6, and the first mounting plate 2 is locked between the two first locking nuts 6. The two flange plates 2701 of the welded H-beam 27 are located between the two opposite rollers 5, preventing the welded H-beam fillet weld cleaning device from falling off the welded H-beam 27. It is easy to adjust and suitable for welded H-beams 27 of different widths, with good adaptability. The roller 5 can avoid the welded H-beam fillet weld cleaning device from getting stuck during the movement of the welded H-beam 27 along its length. The welded H-beam fillet weld cleaning device moves at a uniform speed, and completes uniform grinding and cleaning of the fillet weld of the welded H-beam 27, improving the grinding and cleaning quality of the fillet weld of the welded H-beam 27.

[0024] As one possible implementation method, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, two first screws 1 are arranged parallel to each other at intervals. Four first mounting plates 2 are respectively arranged at the top of both ends of the two first screws 1. Two first positioning rings 202 are arranged at the bottom of the first mounting plates 2. The first screws 1 pass through the two first positioning rings 202 corresponding to the first mounting plates 2. Two second locking nuts 7 are respectively arranged at both ends of the first screws 1. The two first positioning rings 202 of the first mounting plates 2 are located between the two corresponding second locking nuts 7. The two first mounting plates 2 on the same side of the two first screws 1 are arranged opposite each other. Two second positioning rings 203 are arranged at the top of the first mounting plates 2. The first mounting plates 2 also include a third screw 8. The third screw 8 passes through the second positioning rings 203 of the two first mounting plates 2 on the same side of the two first screws 1 in sequence. Two third locking nuts 9 are respectively arranged at both ends of the third screw 8. The two second positioning rings 203 of the first mounting plates 2 are located between the two corresponding third locking nuts 9.

[0025] Two parallel first screws 1 are arranged at intervals, and together with four first mounting plates 2 and four traveling wheels 3, they are assembled on the flange plate 2701 of the welded H-beam 27. This improves the stability of the welded H-beam fillet weld cleaning device, allowing it to move smoothly and at a uniform speed on the flange plate 2701 of the welded H-beam 27, and to uniformly grind and clean the fillet weld of the welded H-beam 27, further improving the grinding and cleaning quality of the fillet weld of the welded H-beam 27. The first positioning ring 202 and the second positioning ring 203 are respectively welded to the bottom and top of the first mounting plate 2. The third screw 8 is used to connect and fix the two first mounting plates 2 on the same side. After loosening the corresponding third locking nut 9 and adjusting the distance between the two first mounting plates 2 on the same side, the corresponding third locking nut 9 is tightened, and the two second positioning rings 203 of the first mounting plate 2 are locked between the two corresponding third locking nuts 9. Loosen the second locking nut 7, adjust the first mounting plate 2 along the length of the first screw 1 so that the traveling wheel 3 is centered on the top surface of the flange plate 2701 corresponding to the welded H-beam 27, and lock the second locking nut 7. The two first positioning rings 202 are locked between the two corresponding second locking nuts 7. The adjustment is convenient and it is suitable for welded H-beams 27 of different widths, with good adaptability.

[0026] As one possible implementation method, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the driving mechanism includes a drive motor 10, which is disposed on the top of the first mounting plate 2. The output shaft of the drive motor 10 is provided with a first pulley. The traveling wheel 3 is disposed on the bottom of the first mounting plate 2. The axle of the traveling wheel 3 is provided with a second pulley. The first mounting plate 2 has a first through hole 204 and also includes a belt 11. The belt 11 passes through the first through hole 204 and is connected to the first pulley and the second pulley for transmission.

[0027] The drive motor 10 starts working, causing its output shaft to rotate, which in turn rotates the first pulley. This, in turn, drives the second pulley via belt 11, which in turn rotates the axle of the traveling wheel 3, causing the traveling wheel 3 to rotate. The traveling wheel 3 moves along the length of the welded H-beam 27 on the flange plate 2701, moving the first mounting plate 2 and the grinder 16 to grind and clean the fillet weld of the welded H-beam 27. Bolt holes are provided on the first mounting plate 2, and the drive motor 10 is fixedly mounted on it with bolts. The first and second pulleys are identical pulleys. The first pulley is fixed to the output shaft of the drive motor 10, and the second pulley is fixed to the axle of the traveling wheel 3 via an interference fit or key connection. The first and second pulleys are positioned opposite each other. The first through hole 204 is a rectangular hole, with a width greater than the width of belt 11 and a length greater than the outer diameter of the pulley, to avoid interference between the belt and the first through hole 204 during belt transmission. A U-shaped wheel mounting base is welded to the bottom of the first mounting plate 2. Wheel axle mounting holes are drilled in the two arms of the wheel mounting base. The wheel 3 is fixed to the axle using an interference fit or key connection. Both ends of the axle are rotatably connected to the corresponding wheel axle mounting holes. A second pulley is mounted on the end of the axle closest to the drive motor 10. A retaining groove is provided on the outer end of the other end of the axle, and a retaining spring is installed in the groove to prevent the axle from falling off. Further, bearings are fixedly installed in the wheel axle mounting holes using an interference fit. The interference fit or key connection of both ends of the wheel axle of the wheel 3 to the corresponding bearings facilitates smooth rotation of the axle, driving the wheel 3 to move at a uniform speed on the flange plate 2701 corresponding to the welded H-beam 27. The drive motor 10 and the grinder 16 can be powered by an external power source.

[0028] As one possible implementation method, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a second mounting plate 12 is provided between the two first screws 1. The second mounting plate 12 has two second through holes, and a fourth screw 13 is provided in the two second through holes. Two fourth locking nuts 14 are provided at the upper end of the fourth screw 13. The upper end of the fourth screw 13 passes through the corresponding second through hole of the second mounting plate 12. The second mounting plate 12 is located between the two fourth locking nuts 14. A third mounting plate 15 is provided at the lower end of the two fourth screws 13. The grinder 16 is mounted on the third mounting plate 15.

[0029] The second mounting plate 12 is used to mount and support the fourth screw 13. The third mounting plate 15 is welded to the lower end of the fourth screw 13 and is used to mount and support the grinder 16. Loosen the corresponding fourth locking nut 14, move the corresponding fourth screw 13 up and down to adjust its height, thereby adjusting the height of the corresponding third mounting plate 15, and then adjusting the height of the grinding head 21 of the grinder 16. This achieves vertical height adjustment of the grinding head 21 of the grinder 16, bringing its height closer to the fillet weld of the welded H-beam 27. After adjusting the height, tighten the corresponding fourth locking nut 14.

[0030] As one possible implementation method, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the second mounting plate 12 has two third positioning rings 1201 respectively on the two side walls facing the two first screws 1, and two fifth locking nuts 17 are respectively provided at both ends of the first screws 1. The first screws 1 pass through the two third positioning rings 1201 on the corresponding side walls of the second mounting plate 12 in sequence, and the two third positioning rings 1201 on the corresponding side walls of the second mounting plate 12 are located between the two corresponding fifth locking nuts 17.

[0031] The third positioning rings 1201 on both sides of the second mounting plate 12, in conjunction with the fifth locking nut 17, are used to adjust and fix the position of the second mounting plate 12 along the axial direction of the first screw 1. Moving the corresponding second mounting plate 12 along the length direction of the corresponding first screw 1 adjusts the distance between the grinding head 21 of the corresponding grinder 16 and the flange plate 2701 of the welded H-beam 27, thus achieving horizontal adjustment of the grinding head 21 of the grinder 16. Combined with vertical height adjustment of the grinding head 21 of the grinder 16, this ensures that the grinding head 21 of the grinder 16 contacts the fillet weld of the welded H-beam 27. The third positioning rings 1201 are welded to the side walls of the second mounting plate 12.

[0032] As one possible implementation method, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the third mounting plate 15 is provided with a mounting cylinder 18 that is closed at one end. A compression spring 19 is provided inside the closed end of the mounting cylinder 18. The grinder 16 is sleeved inside the mounting cylinder 18. The two ends of the compression spring 19 abut against the tailstock of the grinder 16 and the closed end of the mounting cylinder 18, respectively. A baffle 20 is provided at the open end of the mounting cylinder 18. The baffle 20 has a mounting hole. The main shaft of the grinder 16 rotates through the mounting hole and is fixedly connected to the grinding head 21.

[0033] The compression spring 19 ensures that the grinding head 21 of the grinder 16 comes into contact with the welded H-beam fillet weld, uniformly grinding and removing the weld, thus improving the quality of the weld removal. The outer diameter of the grinder 16's spindle is smaller than the inner diameter of the mounting hole in the baffle 20, preventing interference between the grinder 16's spindle and the mounting hole in the baffle 20 during rotation. The baffle 20 can have the mounting hole formed by a single piece of plate or by two plates with arc-shaped notches; the arc-shaped notches of the two plates together form the mounting hole.

[0034] As one possible implementation method, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the third mounting plate 15 is provided with two arc-shaped holes 1501, the openings of the two arc-shaped holes 1501 are arranged opposite each other, the mounting cylinder 18 is provided with two clamps 22, the clamps 22 are provided with a fifth screw 23, the fifth screw 23 passes through the corresponding arc-shaped hole 1501 and is threadedly connected to the sixth locking nut 24.

[0035] Loosen the corresponding sixth locking nut 24, move and adjust the fifth screw 23 within the arc-shaped hole 1501 to adjust the angle of the grinding head 21 of the grinder 16 and the distance between the fillet weld of the welded H-beam 27, so that the grinding head 21 of the grinder 16 covers the fillet weld of the welded H-beam 27, and tighten the corresponding sixth locking nut 24 to better grind and remove the fillet weld of the welded H-beam 27, thus achieving a better grinding and removal effect.

[0036] As one possible implementation method, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, a guide rod 25 is provided at the closed end of the mounting cylinder 18, and spring pressure plates 26 are respectively provided at both ends of the compression spring 19. The spring pressure plates 26 at both ends of the compression spring 19 abut against the tailstock of the grinder 16 and the closed end of the mounting cylinder 18, respectively. A third through hole is opened in the spring pressure plate 26 near the closed end of the mounting cylinder 18, and the free end of the guide rod 25 passes through the corresponding third through hole of the spring pressure plate 26 and is sleeved in the compression spring 19. The free end of the guide rod 25 is the other end of the connection between the guide rod 25 and the closed end of the mounting cylinder 18.

[0037] If a hole is made at the closed end of the mounting cylinder 18, the guide rod 25 extends into the mounting cylinder 18 through the hole and is welded to the closed end of the mounting cylinder 18. The third through hole of the spring pressure plate 26 near the closed end of the mounting cylinder 18 passes through the guide rod 25 and is installed at the closed end of the mounting cylinder 18. The length of the guide rod 25 extending into the mounting cylinder 18 through the hole is less than the initial length of the compression spring 19. One end of the compression spring 19 is fitted onto the guide rod 25, and the other end of the compression spring 19 is fitted with the spring pressure plate 2. The grinder 16 is then fitted into the mounting cylinder, and the spindle of the grinder 16 rotates through the baffle 20. The mounting hole is fitted with a baffle 20 over the open end of the mounting cylinder 18. The tailstock of the grinder 16 is in contact with the spring pressure plate 26 at the closed end away from the mounting cylinder 18. The compression spring 19 is in contact with both the spring pressure plate 26 at the closed end of the mounting cylinder 18 and the spring pressure plate 26 at the closed end of the mounting cylinder 18. The spring pressure plate 26 at the closed end of the mounting cylinder 18 is in contact with the inner bottom wall of the closed end of the mounting cylinder 18. The compression spring 19 is in a compressed state, which allows the grinding head 21 of the grinder 16 to better contact the welded H-beam fillet weld, improving the grinding and cleaning quality of the welded H-beam fillet weld. The guide rod 25 guides the installation of the spring pressure plate 26 at the closed end of the mounting cylinder 18 and also guides the compression spring 19. The spring pressure plate 26 supports both ends of the compression spring 19 and is slidably fitted inside the mounting cylinder 18. If the length of the grinder 16 is insufficient, a spring pressure plate 26 can be added to the closed end of the mounting cylinder 18 to ensure that the grinder 16 is pressed tightly inside the mounting cylinder 18. The baffle 20 can be screwed, snap-fitted, or fixed to the open end of the mounting cylinder 18 using existing technologies.
