Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a welding device for producing angle steel towers. Background Art

[0002] Transmission line towers are tower-shaped buildings used for power transmission. Their structural characteristics are that all types of towers are space truss structures. The rods are mainly composed of single equilateral angle steel or combined angle steel. The materials generally used are Q235 and Q345. The rods are connected by rough bolts, which are connected by shear force. The whole tower is composed of angle steel, connecting steel plates and bolts. Individual parts such as tower feet are welded from several steel plates into an assembly. Therefore, hot-dip galvanizing, anti-corrosion, transportation and construction are extremely convenient. For towers with a height of less than 60m, foot nails are set on one of the main materials of the tower to facilitate construction workers to climb the tower.

[0003] A Chinese patent application with publication number CN117773428A discloses a welding device for producing prefabricated building components, including a workbench, a support plate 1 is fixedly connected to the middle part of the front side of the upper end of the workbench, an electric push rod 3 is fixedly connected to the upper side of the rear end surface of the support plate 1, a welding gun is fixedly connected to the piston end of the electric push rod 3, collection boxes are placed on both sides of the upper end surface of the workbench, and a splash-proof percussion-type welding slag collection mechanism for collecting welding slag at the steel bar weld is provided on the upper end of the workbench.

[0004] In the above technology, after using a welding gun to weld two sections of steel bars, the striking block is controlled to align with the weld and move back and forth to strike the weld to knock out the slag, so that the slag at the weld falls off. However, during the slag knocking process, part of the slag will splash, and the splashproof shell and the exhaust fan cannot handle the slag well. Moreover, when using the device to weld the tower foot of the angle steel tower, since the weld between the steel plates on the tower foot has a dead angle, it is difficult for the device to handle the slag at the dead angle, which will affect the overall welding quality of the tower foot, so that the safety performance of the tower foot is reduced. Summary of the invention

[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figure 1-Figure 6As shown, a welding device for producing angle steel towers includes a welding gun and a base frame 10 for fixing tower feet. The welding gun is operated by a robot. The base frame 10 is installed on an L-shaped positioner. The tower feet include a base plate 20, an angle steel 21 and two reinforcing plates 22 vertically arranged on the base plate 20. The two reinforcing plates 22 are respectively perpendicular to the two right-angle sides of the angle steel 21. A plurality of movable shells 30 are installed on the base frame 10. In this embodiment, the base plate 20 is rectangular, and the shell 30 has four and is respectively perpendicular to the four sides of the base plate 20. An electric push rod 11 for controlling the movement of the shell 30 is installed on the base frame 10. A slag removal component is installed in the shell 30. The slag removal component includes a movable body 30 that can be moved along the length direction of the shell 30. The outer shell 30 is provided with an electric push rod 12 for driving the inner shell 31 to move. In this embodiment, the outer shell 30 has two cavities 1 for installing the inner shell 31, and the outer shell 30 is provided with a negative pressure machine 41 and a collecting box 42. The collecting box 42 is located at the bottom of the outer shell 30. The outer shell 30 has a cavity 2 connected with the collecting box 42, and a conveying member 39 is installed in the cavity 2. The conveying member 39 adopts the existing auger blade conveying device. The outer shell 30 is provided with a motor 1 for driving the conveying member 39 to rotate. A partition 301 is provided between the cavity 2 and the cavity 1, and a strip hole 302 is provided on the partition 301. The strip hole 302 extends along the length direction of the outer shell 30.

[0032] It should be noted that the four outer shells 30 respectively correspond to the two welds between one of the right-angled sides of the angle steel 21 and the base plate 20, the two welds between the other right-angled side of the angle steel 21 and the base plate 20, the two welds between one of the reinforcing plates 22 and the base plate 20, and the two welds between the other reinforcing plate 22 and the base plate 20. Taking one of the right-angled sides of the angle steel 21 as an example, the two inner shells 31 in the outer shell 30 corresponding to the right-angled side respectively correspond one-to-one to the two welds between the right-angled side and the base plate 20.

[0033] like Figure 6-Figure 13 As shown, taking one of the inner shells 31 in the outer shell 30 corresponding to one of the right-angled sides of the angle steel 21 as an example, the outer side of the inner shell 31 has an inclined surface 311, and the inclined surface 311 extends along the length direction of the inner shell 31. When the inner shell 31 extends outward from the outer shell 30, the inclined surface 311 faces the weld between the angle steel 21 and the substrate 20. A plurality of slag removal rollers 32 are installed in the inner shell 31 along the length direction of the inclined surface 311 in rotation at intervals. The outer periphery of the slag removal roller 32 slightly extends outward from the inclined surface 311. The slag removal roller 32 can clean the welding slag at the weld between the angle steel 21 and the substrate 20. The slag removal roller 32 has a cavity three, and the outer periphery of the slag removal roller 32 has a plurality of channels one connected to the cavity three. The end of the channel one close to the outer edge of the slag removal roller 32 has a slag scraping portion 321, and the end of the channel one close to the cavity three has an arc-shaped buffer portion 322. A slag conveying component for conveying the welding slag in the slag removal roller 32 to the collecting box 42 is installed in the cavity three.

[0034] The slag conveying assembly includes a collecting trough 50 fixedly connected to the inner shell 31 and located in the cavity three. The collecting trough 50 is U-shaped, and the U-shaped opening faces upward. A conveying member 51 is rotatably installed in the collecting trough 50. The conveying member 51 is transported in the form of an auger blade. The inner shell 31 has a channel 2 312 connecting the collecting trough 50 and the cavity 2. The conveying member 51 extends into the channel 2 312. A worm gear 35 is fixedly installed at one end of the slag removal roller 32. The worm gear 35 has a slot 351. The cross section of the slot 351 is rectangular. A transmission rod 36 is slidably installed in the conveying member 51 along its length extension direction. The cross section of the transmission rod 36 is rectangular. The conveying member 51 has a slot 351 connected to the slag removal roller 32. The mating hole for the transmission rod 36 has a rectangular cross-section. One end of the transmission rod 36 has a block 361 that cooperates with the slot 351. The end of the transmission rod 36 close to the worm gear 35 is connected to the inner shell 31 through an elastic member 2, and the elastic member 2 is specifically a second spring. The inner shell 31 is slidably installed with a baffle 34 that cooperates with the second channel 312 through an elastic member 1 on the side facing the partition 301, and the elastic member 1 is specifically a first spring. The baffle 34 has a through hole 341 that cooperates with the second channel 312, and a mating block 303 that cooperates with the baffle 34 is installed on the partition 301. The end of the transmission rod 36 away from the worm gear 35 has a conical block 362 that cooperates with the baffle 34.

[0035] It should be noted that when the inner shell 31 is stored in the outer shell 30, the through hole 341 is connected to the strip hole 302, and the matching block 303 can stop the baffle 34 so that the baffle 34 slides relative to the inner shell 31 and the elastic member 1 is stretched, so that the channel 2 312 and the through hole 341 are in a connected state. At this time, the transmission rod 36 slides under the action of the elastic member 2 so that the conical block 362 enters the through hole 341, and the clamping block 361 can enter the clamping groove 351 and clamp therewith. Therefore, when the worm gear 35 rotates, the slag removal roller 32 and the conveying member 1 51 can rotate together, so that the welding slag in the collecting tank 50 is transported by the conveying member 1 51 through the channel 2 312, the through hole 341 and the like in sequence. 341 and the strip hole 302 are transported to the second cavity, and then transported to the collection box 42 by the second conveying member 39; when the inner shell 31 slides out of the outer shell 30, the matching block 303 is separated from the stop on the baffle 34, the baffle 34 slides relative to the inner shell 31 and the elastic member 1 contracts, so that the channel 2 312 and the through hole 341 are in a staggered state, the channel 2 312 is blocked by the baffle 34, and the conical block 362 is squeezed by the through hole 341 so that the conical block 362 moves into the channel 2 312, at this time, the block 361 is separated from the slot 351, and the elastic member 2 is compressed, so that when the worm gear 35 rotates, the slag removal roller 32 can rotate and the conveying member 1 51 stops rotating.

[0036] The end of the inner shell 31 is rotatably installed with a slag removal piece, which can clean the welding slag near the inner top corner of the angle steel 21. The slag removal piece includes a steel brush 331 and a base block 332. The steel brush 331 is generally arc-shaped, and the base block 332 is provided with an air hole 333. The air hole 333 is connected to the negative pressure machine 41 through a pipeline. When the air hole 333 corresponds to the weld, the negative pressure machine 41 can suck the welding slag at the weld. A worm 37 for driving the slag removal roller 32 to rotate is rotatably installed in the inner shell 31. The worm 37 extends along the length direction of the inner shell 31. A motor 2 for driving the worm 37 to rotate is installed in the inner shell 31. The worm 37 is located below the worm wheel 35. A gear 1 334 is fixedly installed at the end of the slag removal piece. A rack 38 cooperating with the gear 1 334 is slidably installed in the inner shell 31 through an elastic member 3. The elastic member 3 is specifically a third spring. The rack 38 can slide along the length direction of the inner shell 31. The rack 38 is located above the gear 1 334, and the gear 2 323 is coaxially fixedly installed on one side of the worm gear 35 on the slag removal roller 32 adjacent to the slag removal piece, and the gear 2 323 meshes with the rack 38; when the inner shell 31 slides out of the outer shell 30, by controlling the motor 2 to run in the forward direction, the slag removal roller 32 and the slag removal piece can rotate in the forward direction. It should be noted that during the rotation of the slag removal piece, the steel brush 331 first cleans the weld, and then the steel brush 331 rotates into the inner shell 31, the base block 332 rotates out of the inner shell 31, and the air hole 333 is in a state facing the weld. As the slag removal roller 32 continues to rotate forward, under the action of the elastic member 3, the air hole 333 can maintain a state facing the weld; by controlling the motor 2 to run in the reverse direction, the slag removal piece can be reset so that the steel brush 331 rotates out of the inner shell 31 and contacts the weld between the angle steel 21 and the base plate 20, and the base block 332 rotates into the inner shell 31.

[0037] Specific working principle: Reference Figure 1-Figure 13 After the angle steel 21 and the two reinforcing plates 22 are fixed to the base plate 20 by spot welding, the tower foot is fixed to the base frame 10, and then the tower foot is fully welded using a welding gun and an L-type positioner.

[0038] Taking the two welds between the inner right angle of the welding angle steel 21 and the base plate 20 as an example, after the welding gun fully welds one of the welds, the outer shell 30 corresponding to the weld is controlled to approach the angle steel 21, and then the inner shell 31 corresponding to the weld in the outer shell 30 is controlled to extend outward from the outer shell 30 until the end of the inner shell 31 stops at the right angle side of the angle steel 21. During this process, the steel brush 331 can completely rub the weld to remove the welding slag on the surface of the weld, and then the motor 2 is controlled to run forward, and the slag removal roller 32 can rotate forward so that the scraping part 321 can scrape the welding slag on the surface of the weld, and the air hole 333 rotates to a state facing the weld, and the welding slag scraped by the scraping part 321 can enter the buffer part 322 through the channel 1, and then when the buffer part When 322 moves to above the collecting trough 50, the welding slag in the buffer part 322 can be dumped into the collecting trough 50; then the inner shell 31 is controlled to be gradually stored in the outer shell 30. During this process, the scraping part 321 can scrape the welding slag on the surface of the weld better, and the air hole 333 can absorb the floating slag on the surface of the weld. When the inner shell 31 is stored in the outer shell 30, the conveying part 1 51 can rotate together with the slag removal roller 32, so that the welding slag in the collecting trough 50 is conveyed to the cavity 2 by the conveying part 1 51 through the channel 2 312, the through hole 341 and the strip hole 302 in sequence, and then conveyed to the collection box 42 by the conveying part 2 39. When the welding slag is transported, the motor 2 is controlled to run in reverse, and the slag removal part can be reset.

[0039] It is understandable that welding slag will splash during the welding process of the welding gun. Since the above-mentioned weld has been cleaned and the welding slag at the intersection of the two welds has been cleaned by the slag removal part, when the other weld is welded next, there will be no welding slag that affects the welding in the other weld, which is conducive to the high-quality welding of the other weld by the welding gun.

[0040] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
