The specific embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the invention will be further described.
The present invention is for submerged arc welding, especially the cleaning of narrow-clearance submerged arc welding postwelding welding bead: adopt a welding walking dolly, what be connected with dolly is height adjuster, height adjuster is connected with high-strength connecting plate, and the narrow-clearance submerged arc welding slag cleaning plant that slag stamping machine, slag cleaner and slag recover are integrated is housed on high-strength connecting plate.The running trolley of narrow-clearance submerged arc welding slag cleaning plant and the dolly of submerged arc welding move on same track, and running trolley is across above weld seam, and the center of dolly and weld seam center are on an axis.In trolley travelling process, height adjuster, slag stamping machine, slag cleaner and slag recover carry out work simultaneously separately.In welding process, due to constantly carrying out of welding, the fusion penetration degree of depth shoals gradually, and the height of slag improves constantly, and utilizes height adjuster can regulate the height of slag stamping machine, slag cleaner and slag recover.Height adjuster makes whole system in height play the effect of adjusting by inner height adjusting screw and the effect of height adjusting nut, and drives high-strength connecting plate that slag stamping machine, slag cleaner and slag recover are worked simultaneously.Slag stamping machine adopts the principle work of crankshaft-link rod, motor operation, and slag is smashed bar to pieces and is moved up and down, it is taper that slag is smashed head to pieces, therefore the slag on welding bead is subject to the percussion that sharper slag is smashed head to pieces, and the slag solidifying can be broken, forms less slag.Because the width of weld seam is different, smash slag to pieces head and be furnished with the model varying in size.The bottom of slag cleaner is a steel wire cleaning brush, motor operation, and wire brush starts rotation, and cleaning brush can be cleared up each position in gap, and brush more fully contacts with weld seam, and slag is pulverized more thorough.Because the Toughness Ratio of wire brush brush is better, can not damage to some extent the sidewall of steel plate and welding bead, can in scale removal process, not make the inner stress that produces of weldment yet, because the width of weld seam is different, smash slag to pieces head and be furnished with the model varying in size, the brush of this kind of shape of design can be cleared up each position of welding bead in the situation that brush holder support does not touch sidewall, reaches the object of cleaning completely.After slag is pulverized, adopt the slag in slag recovery tube butt welded seam to clear up, can not leave any impurity and butt welded seam quality impacts.Adopt the steel pipe of flat to carry out slag recovery, because slag mostly is flat pattern, therefore, the steel pipe of this kind of shape is more conducive to the slag that cleaning is not smashed completely.
Component names in figure: 1-workpiece, 2-weld seam, 3-trolley travelling track, the high-strength connecting plate of 4-, 5-slag stamping machine, 6-slag cleaner, 7-height adjuster, 8-slag recover, 9-slag recovery tube, 10-running trolley, 11-highly regulates motor, 12-height adjusting screw, 13-height adjusting nut, 14-bolt, 15-set bolt, 16-highly regulates location-plate, 17-slag is smashed motor to pieces, the broken location-plate of 18-, 19-rotary disk, 20-connecting rod, 21-binding clasp, 22-slag is smashed bar to pieces, 23-slag cleaning motor, 24-slag cleaning brush.
Workpiece 1 docks weldment while welding for narrow-clearance submerged arc welding, has weld seam 2 on workpiece 1, is placed with trolley travelling track 3 on workpiece 1, running trolley 10 direction along ng a paths is placed, and be across on weld seam.Welding tractor is connected with height adjuster 7, and height adjuster is by highly regulating motor 11, height adjusting screw 12, height adjusting nut 13, bolt 14, highly regulating location-plate 15, set bolt 16 to form, as shown in Figure 1 and Figure 2.On the top of height adjuster 7, be highly to regulate motor 11, height adjusting screw 12 is equipped with in the inside of height adjuster 7, and on height adjusting screw 12, cover has height adjusting nut 13, the below of height adjusting nut 13 is highly to regulate location-plate 16, height emphasizes that nut 13 is connected by bolt 14 with highly regulating between location-plate, the below that highly regulates location-plate 16 is high-strength connecting plate 4, by hold-down nut 15, makes highly to regulate location-plate 16 to be connected with high-strength connecting plate 4.When highly regulating motor 11 work, 12 rotations of height adjusting screw, by the operation principle of leading screw, rotatablely moving of motor changed into the rectilinear motion of leading screw, height adjusting screw 12 constantly rotates, the height adjusting nut 13 being attached thereto is done vertical motion, thereby regulate location-plate 16 and high-strength connecting plate 4 to do the motion of vertical direction with dynamic height, by the motion of high-strength connecting plate 4, reach the effect highly regulating, and driven slag stamping machine 5, slag cleaner 6 and 8 motions of slag recover.Slag stamping machine is smashed motor 17, broken location-plate 18, rotary disk 19, connecting rod 20, binding clasp 21 and slag to pieces by slag and is smashed bar 22 to pieces and form.As shown in Figure 1, Figure 3, high-strength connecting plate 4 tops are connected with broken location-plate 18, a side at broken location-plate 18 is equipped with the broken motor 17 of slag, opposite side is equipped with rotary disk 19, the turning cylinder of the broken motor 17 of slag sees through broken location-plate 18 and is connected with the rotary disk 19 of opposite side, on the circumference of rotary disk 19, connect a connecting rod 20, the below of connecting rod is connected with binding clasp 21, slag can be smashed to pieces to bar 22 work asynchronously with rotary disk 19 by binding clasp 21.When slag is smashed motor 17 work to pieces, by couple axle, drive rotary disk 19 to rotate, the connecting rod 20 being connected with rotary disk 19 carries out circular motion along disk, and rotatablely moving of rotary disk 19 is converted into the motion that connecting rod 20, binding clasp 21 and slag are smashed the vertical direction of bar 22 to pieces.One end that slag is smashed bar 22 to pieces is conical head, slag smash to pieces head also move up and down.Slag cleaner is comprised of slag cleaning motor 23, slag cleaning brush 24.As shown in Figure 4, slag cleaning motor 23 is connected to the top of high-strength connecting plate 4, is connected with slag cleaning brush 24 below high-strength connecting plate 4, and slag cleaning motor 23 is connected with slag cleaning brush 24, the bottom of slag cleaning brush 24 is connected with brush, and brush is replaceable according to the width difference of weld seam.When 23 work of slag cleaning motor, slag cleaning brush 24 is along with motor rotates, and the brush of brush holder support bottom also synchronously rotates.Slag recover 8, can be by the slag sucking-off in welding bead by slag recovery tube 9 by reclaiming the effect of dynamic equipment, and slag enters recovery dynamic equipment and by scum pipe, slag discharged.
