Description

Technical Field

[0001] This application relates to the field of steel cladding technology for beams and columns, and more particularly to an automatic welding auxiliary device for the steel cladding process for beams and columns. Background Technology

[0002] In existing building renovation projects, the beam-column steel cladding technique is frequently used. Taking column steel cladding as an example, this technique involves installing four vertically arranged angle steels against the four external corners of the column, and then arranging horizontal steel gusset plates at certain intervals along the vertical direction on all four sides of the column and welding them to the angle steels. Currently, all welding of the angle steels and gusset plates is done manually on-site, which is inefficient, and the welding quality is difficult to control due to the varying skill levels of the welders. Utility Model Content

[0003] The purpose of this application is to address the problems of low accuracy and efficiency in the automatic welding of angle steel and gusset plates in the beam-column steel cladding process in existing technologies. Therefore, this application provides an automatic welding auxiliary device for the beam-column steel cladding process. Through the cooperation of a mounting frame, positioning components, and proximity switches, the weld seam area is positioned, and the welding torch can be stably installed using a welding torch clamp, thereby assisting in the accurate and efficient automatic welding of angle steel and gusset plates in the beam-column steel cladding process.

[0004] This application provides an automatic welding auxiliary device for the steel cladding process of beams and columns, including:

[0005] The mounting bracket includes an angle steel bearing position and multiple lacing plate bearing positions, and allows the angle steel and multiple lacing plates to be located in welding positions;

[0006] The positioning assembly includes an angle steel positioning member and a gusset plate positioning rod disposed on the mounting frame, wherein the angle steel positioning member is used to abut the angle steel against the mounting frame;

[0007] The walking mechanism includes multiple walking guide rails disposed on the mounting frame, and a walking base that can walk along the walking guide rails;

[0008] and a welding torch clamp and a proximity switch mounted on the walking base; wherein,

[0009] The positioning rod of the lacing plate positions multiple lacing plates, so that the multiple lacing plates overlap the angle steel with the same length along the length direction of the angle steel.

[0010] The walking guide rail is arranged parallel to the gusset plate positioning rod;

[0011] The proximity switch, driven by the walking mechanism, positions the multiple lacing plates sequentially. The welding gun fixture is used to mount the welding gun, so that the welding gun can weld the multiple lacing plates sequentially.

[0012] By adopting the above technical solution, a welding reference is provided through the mounting bracket, eliminating the need for spot welding pre-fixation, thus improving welding efficiency. The positioning components ensure that the angle steel and gusset plate are stabilized in the welding state. In particular, the gusset plate positioning rod uniformly confirms the length of the gusset plate overlapping the angle steel, making operation convenient and reliable. This length is typically the preset length of the transverse weld. Simultaneously, proximity switches sequentially position the gusset plates as the welding operation progresses, allowing for the positioning of the weld area according to predetermined dimensions or positions (preset lengths of the transverse and longitudinal welds). This means that weld positioning is achieved through a single sensor data point combined with multiple predetermined data points, improving positioning accuracy and efficiency. Furthermore, simultaneous welding and positioning further enhances welding precision and efficiency.

[0013] In some embodiments, it also includes:

[0014] The lifting mechanism is detachably connected to the walking base via a connector.

[0015] A telescopic mechanism, connected to the lifting mechanism;

[0016] The welding torch clamp is mounted on the telescopic mechanism and can move along the length of the gusset plate with the telescopic mechanism;

[0017] The proximity switch is located at the bottom of the fixed base of the lifting mechanism or the telescopic mechanism, and the distance between the lifting mechanism and the angle steel can be adjusted by the connecting piece, so that the proximity switch is close to the end of the overlap position of the angle steel and the connecting plate.

[0018] By adopting the above technical solution, the welding torch can be moved in three dimensions through the walking mechanism, lifting mechanism and telescopic mechanism, which improves the welding flexibility. Furthermore, the lifting mechanism and walking mechanism can be separated by the connecting parts, which improves the portability of the device. At the same time, the distance between the proximity switch and the angle steel set at the bottom of the lifting mechanism can also be adjusted by the connecting parts, so that it is located in the appropriate detection position, close to the weld, improving the weld positioning accuracy and thus improving the welding accuracy.

[0019] In some embodiments, the proximity switch is an inductive proximity switch, a reflective photoelectric switch, or a contact mechanical switch;

[0020] A detection avoidance channel is formed between each of the aforementioned gusset plate bearing positions. The detection avoidance channel is located at the end of the overlap position of the angle steel and the gusset plate, so that the proximity switch is not triggered.

[0021] The above technical solution, which uses inductive proximity switches, reflective photoelectric switches, or contact mechanical switches, is suitable for the harsh environment of steel beam and column construction sites. It only needs to be installed above the mounting frame, making assembly convenient. Furthermore, by setting a detection avoidance channel at the end of the overlap position of the angle steel and the gusset plate, the probability of false triggering is reduced, further improving the positioning accuracy.

[0022] In some embodiments, two welding torch clamps are symmetrically arranged;

[0023] The two welding torch clamps are mounted on the mounting plate and can move synchronously with the mounting plate. The mounting plate is connected to the telescopic mechanism.

[0024] The distance between the two welding torch clamps is adjustable, so that the welding distance between the two corresponding welding torches is adapted to the width of the lacing plate, so as to weld both sides of the lacing plate simultaneously.

[0025] By adopting the above technical solution, two welding guns can be installed and welded simultaneously using two welding gun clamps, which further improves welding efficiency; the distance between the two welding gun clamps is adjustable, thereby adjusting the distance between the two welding guns and adapting to lacing plates of different widths, thus improving the versatility of the device.

[0026] In some embodiments, the travel guide rail is mounted on the mounting frame via a lifting member, the lifting member being disposed on the side of the gusset plate bearing position;

[0027] The top of the lifting member is provided with a limiting groove that is adapted to the traveling guide rail, so that the traveling guide rail can be embedded in the limiting groove.

[0028] The lifting component and the mounting bracket are magnetically attached.

[0029] By adopting the above technical solution, a gap is created between the travel guide rail and the mounting bracket through the lifting component, which facilitates the placement of the gusset plate; furthermore, the lifting component and the mounting bracket are installed through magnetic attraction, making assembly convenient and improving overall efficiency; at the same time, the limiting groove of the lifting component improves the stability, reliability and accuracy of the travel guide rail installation, thereby improving the stability, reliability and accuracy of welding.

[0030] In some embodiments, the mounting bracket is a rectangular frame assembled from multiple square tubes, and the angle steel bearing position is formed by the intersecting two sides of one of the square tubes located at the edge.

[0031] By adopting the above technical solution, a rectangular frame mounting bracket is formed by assembling square tubes, which facilitates temporary assembly in the construction environment and ensures the horizontality and verticality of the mounting bracket, thereby ensuring the accuracy of the formed angle steel bearing position and gusset plate bearing position and improving welding accuracy.

[0032] In some embodiments, the gusset plate positioning rod is an angle steel of the same specification as the angle steel to be welded.

[0033] In some embodiments, the travel guide rail includes a rack disposed on the top surface and limiting protrusions disposed on both sides;

[0034] The walking base includes a driving component, a gear adapted to the rack, and at least two limiting wheels adapted to the two limiting protrusions. The two ends of the limiting wheels are engaged with the upper and lower sides of the limiting protrusions, and the limiting wheels can roll along the limiting protrusions.

[0035] The above technical solution uses a gear and rack transmission to enable the walking mechanism to move, achieving high-efficiency transmission. It is suitable for the harsh environment of the beam and column steel-cladding construction site, has a long service life, and low cost. In addition, it has high load-bearing capacity and can provide a stable and reliable installation and moving platform for the walking base, proximity switches, two welding gun clamps, etc.

[0036] Other features and corresponding beneficial effects of this application will be described in the latter part of the specification, and it should be understood that at least some of the beneficial effects will become obvious from the description in this application.

[0051] The beam-column steel cladding process involves attaching angle steel 1 to the external corner of the beam and column, and then arranging horizontal steel gusset plates 2 at regular intervals on all four sides of the beam and column (the intervals are not less than the width of the gusset plate 2 and are uneven, typically with larger intervals in the middle of the angle steel and smaller intervals at the ends, and denser arrangement). These gusset plates 2 are then welded to the angle steel 1. For a single gusset plate 2, the corresponding weld consists of two transverse welds and one longitudinal weld, matching the shape of the edge of the gusset plate 2. Currently, in construction, manual welding is usually used for each gusset plate, which involves a large amount of work, high construction difficulty, and makes it difficult to guarantee the welding effect.

[0052] Please see Figure 1-4 , Figure 1 This is a schematic diagram illustrating the usage status of this application; Figure 2 for Figure 1 A partially enlarged structural diagram; Figure 3 This is a schematic diagram of the structure of this application; Figure 4 This is another structural diagram of this application.

[0053] This application provides an automatic welding auxiliary device for the beam-column steel encapsulation process, used to mount a welding torch and assist the welding torch in welding multiple gusset plates 2 to angle steel 1 in the beam-column steel encapsulation process. The welding auxiliary device includes a mounting frame 100, a positioning assembly, a traveling mechanism 310, a proximity switch, and a welding torch clamp 340.

[0054] The mounting bracket 100 includes an angle steel bearing position and multiple lacing plate bearing positions, and allows the angle steel 1 and multiple lacing plates 2 to be located in the welding position, so that the front ends of the multiple lacing plates 2 can be sequentially overlapped on the angle steel 1 along its length direction to form a U-shaped weld area composed of two transverse welds and one longitudinal weld. This method eliminates the need for spot welding pre-fixation of the angle steel 1 and the lacing plates 2, thus improving welding efficiency.

[0055] The positioning assembly includes an angle steel positioning member 210 and a lacing plate positioning rod 220 mounted on the mounting frame 100. The angle steel positioning member 210 ensures that the angle steel 1 abuts against the mounting frame 100, guaranteeing the stability of the angle steel 1 during welding. The lacing plate positioning rod 220 ensures that the overlap length of each lacing plate 2 on the angle steel 1 is consistent, which is usually the preset length of the transverse weld, thus ensuring the accuracy of the transverse weld length. Preferably, the lacing plate positioning rod 220 is located at the rear end of the lacing plate bearing position and abuts against the rear end of the lacing plate 2, thereby determining the overlap length between the lacing plate 2 and the angle steel 1 when placing the lacing plate 2, making operation convenient. Furthermore, to ensure that the lacing plate 2 is horizontal, the lacing plate positioning rod 220 can be an angle steel of the same specification as the angle steel to be welded, so that both ends of the lacing plate 2 overlap the angle steel 1. That is, one leg of the angle steel 1 serving as the lacing plate positioning rod 220 supports the lacing plate, and the other leg abuts against the end of the lacing plate. This method is convenient in terms of material availability and is particularly suitable for construction environments. The lacing plate positioning rod 220 can also be a magnetic block, which facilitates fixing it to the mounting bracket.

[0056] The walking mechanism 310 includes multiple walking guide rails 311 mounted on the mounting frame 100, and a walking base 312 that can travel along the walking guide rails 311. The multiple walking guide rails 311 are convenient for transportation and can be connected sequentially to the required walking length according to usage requirements.

[0057] The traveling guide rail 311 is arranged parallel to the lacing plate positioning rod 220. The welding gun clamp 340 and the proximity switch are mounted on the traveling base 312. Thus, the proximity switch can sequentially position multiple lacing plates 2 under the drive of the traveling mechanism 310. The welding gun clamp 340 can be used to mount the welding gun, allowing the welding gun to weld multiple lacing plates 2 sequentially. It should be noted that in the beam-column steel cladding process, an automatic wire feeding welding gun is usually used. This type of welding gun can also be easily fixed directly by the welding gun clamp 340 without the need for an additional wire feeding mechanism.

[0058] It should also be noted that angle steel 1 and gusset plate 2 are standard parts with several standard specifications. At the same time, in the process of steel cladding for beams and columns, the welding standards for angle steel 1 and gusset plate 2 of different specifications are also determined, that is, the lengths of the transverse and longitudinal welds are standardized.

[0059] This method uses proximity switches to sequentially position the lacing plate 2 as the welding operation progresses. For example, it identifies the position of one edge of the lacing plate 2 or any other position that can locate the lacing plate 2. This method utilizes the function of the proximity switch itself and can be used with predetermined dimensions (e.g., the preset length of the transverse weld and the preset length of the longitudinal weld, or the preset length of the transverse weld and the preset length of the longitudinal weld can be determined according to the dimensions of the angle steel 1 and the lacing plate 2) to locate the weld area. That is, by obtaining a detection data through the proximity switch, multiple predetermined data are determined with the help of the angle steel bearing position, the lacing plate bearing position, the lacing plate positioning rod, etc., thereby realizing weld positioning, improving positioning accuracy and efficiency, and enabling positioning while welding, thus improving welding accuracy and efficiency.

[0060] In one embodiment, to further complete the welding of the U-shaped seam, the welding auxiliary device also includes a lifting mechanism 320 and a telescopic mechanism 330, which work in conjunction with the center-moving mechanism 310 to drive the welding torch clamp 340, that is, the welding torch achieves three-dimensional movement to complete the welding and improves the welding flexibility.

[0061] The lifting mechanism 320 is detachably connected to the traveling base 312 via the connector 314.

[0062] The telescopic mechanism 330 is connected to the lifting mechanism 320, and the lifting mechanism 320 and the telescopic mechanism 330 can be separated from the walking mechanism 310 as a whole through the connector 314, which improves the portability of the device.

[0063] The welding torch clamp 340 is mounted on the telescopic mechanism 330 and can move along the length of the gusset plate 2 with the telescopic mechanism 330 to achieve transverse welding of the welding torch and longitudinal welding through the traveling mechanism 310.

[0064] The proximity switch is located at the bottom of the fixed base of the lifting mechanism 320 or the telescopic mechanism 330. The distance between the lifting mechanism 320 and the angle steel 1 can be adjusted via the connecting piece 314, so that the proximity switch is close to the end of the overlap position between the angle steel 1 and the connecting plate 2, i.e., the position indicated by arrow A in the figure. This positions the proximity switch in an appropriate detection position, close to the weld, improving the accuracy of weld positioning and thus improving welding accuracy. Furthermore, this detection position is close to the transverse weld and far from the longitudinal weld. When a transverse weld is used first and then the longitudinal weld, positioning can be achieved simultaneously with the longitudinal welding movement. This makes the various parts of the device compact, controls the overall volume, and reduces interference from high temperature and high brightness during welding on the proximity switch, ensuring positioning accuracy.

[0065] Understandably, when the proximity switch is adjusted to the appropriate inspection position, it moves only longitudinally with the traveling mechanism 310, and not with the lifting mechanism 320 or the telescopic mechanism 330.

[0066] In one embodiment, the proximity switch is an inductive proximity switch, a reflective photoelectric switch, or a contact mechanical switch 400. This type of proximity switch is suitable for the harsh environment of steel beam and column construction sites and only needs to be installed above the mounting bracket 100, making assembly convenient. Inductive proximity switches or reflective photoelectric switches are easy to assemble and provide precise positioning; while contact mechanical switches 400 are less expensive, but typically include a rotatable cantilever wheel for contacting the connecting plate 2. On the one hand, the cantilever wheel is relatively large, requiring a high spacing between the connecting plates 2; on the other hand, the cantilever wheel needs to rotate frequently during the detection process, making it difficult to guarantee its service life and reliability.

[0067] In one embodiment, a detection avoidance channel 110 is formed between each lacing plate bearing position. The detection avoidance channel 110 is located at the end of the overlapping position of the angle steel 1 and the lacing plate 2, so that the proximity switch is not triggered, thereby reducing the probability of false triggering and further improving the positioning accuracy.

[0068] In one embodiment, two welding torch clamps 340 are symmetrically arranged, allowing two welding torches to be mounted and welded simultaneously, further improving welding efficiency. Preferably, the two welding torch clamps 340 are mounted on a mounting plate and can move synchronously with the mounting plate, which is connected to the telescopic mechanism 330. Furthermore, the distance between the two welding torch clamps 340 is adjustable, so that the welding distance between the corresponding two welding torches matches the width of the lacing plate 2, enabling synchronous welding of both sides of the lacing plate 2. This accommodates lacing plates 2 of different widths (i.e., different longitudinal weld lengths), improving the versatility of the device.

[0069] It should also be noted that the welding angle is crucial to ensure welding quality. When welding this U-shaped weld with a single welding torch, the first transverse and longitudinal seams can usually be welded at the same angle, but the second transverse seam is symmetrical to the first transverse seam, and its welding angle also needs to be symmetrical. That is, the welding torch needs to be rotated significantly when welding the second transverse seam.

[0070] This welding auxiliary device uses two welding torch clamps 340, which enables two welding torches to simultaneously perform transverse welding and then longitudinal welding. That is, the two welding torches can simultaneously extend outwards to symmetrically weld two transverse seams, and then move forward to weld the longitudinal seam (usually the welding torches have an emergency stop function, that is, the first welding torch moves forward and detaches from the workpiece (lacing plate) and automatically stops working, while the second welding torch continues to contact the workpiece and continues to work). This eliminates the need to adjust the welding torch angle, thereby simplifying the structure of the welding torch clamp 340, controlling the overall weight, volume and cost of the device, and also simplifying the control of welding torch movement.

[0071] During construction, the welding gun angle can be adjusted and fixed using the welding gun clamp 340 according to specific welding requirements, thereby further improving welding precision.

[0072] In one embodiment, the travel guide rail 311 is mounted on the mounting frame 100 by a lifting member 313. The lifting member 313 is located on the side of the gusset plate bearing position, that is, the lifting member 313 creates a gap between the travel guide rail 311 and the mounting frame 100, thereby facilitating the placement of the gusset plate 2.

[0073] In one embodiment, the lifting component 313 and the mounting bracket 100 are magnetically attached, which facilitates assembly and improves overall efficiency.

[0074] In one embodiment, the top of the lifting member 313 is provided with a limiting groove that is adapted to the travel guide rail 311, and the travel guide rail 311 can be embedded in the limiting groove. The limiting groove of the lifting member 313 improves the stability, reliability and accuracy of the installation of the travel guide rail 311, thereby improving the welding stability, reliability and accuracy.

[0075] In one embodiment, the mounting bracket 100 is a rectangular frame assembled from multiple square tubes, and the two intersecting sides of one of the square tubes at the edge form angle steel bearing positions. This facilitates temporary assembly in the construction environment and allows for easy expansion of the size at any time. It also ensures the horizontality and verticality of the mounting bracket 100, thereby ensuring the accuracy of the formed angle steel bearing positions and gusset plate bearing positions and improving welding accuracy.

[0076] In one embodiment, the walking guide rail 311 includes a rack disposed on the top surface, and the walking base 312 includes a drive component and a gear adapted to the rack. The walking mechanism 310 moves through the rack and pinion transmission, which can achieve efficient transmission and is suitable for the harsh environment of the beam and column steel-clad construction site. It has a long service life and low cost; and has high load-bearing capacity, which can provide a stable and reliable installation and moving platform for other parts of the three-dimensional mobile device, as well as the proximity switch and the two welding guns.

[0077] Furthermore, since the angle steel 1 that matches the crossbeam in the beam-column steel-cladding process is usually very long, the corresponding travel guide rail 311 is also relatively long. To facilitate the transportation and carrying of the device, the travel guide rail 311 can be composed of multiple pieces spliced ​​together. Using a gear and rack transmission also facilitates the splicing of the travel guide rail 311. To optimize the welding effect, the splicing position of the travel guide rail 311 should avoid the front projection surface of the gusset plate 2.

[0078] In one embodiment, the walking guide rail 311 is provided with limiting protrusions on both sides, and the walking base 312 includes at least two limiting wheels that are adapted to the two limiting protrusions one by one. The two ends of the limiting wheels are engaged with the upper and lower sides of the limiting protrusions, and the limiting wheels can roll along the limiting protrusions, thereby improving the stability and reliability of the connection between the walking base 312 and the walking guide rail 311, and is small in size and easy to assemble.

[0079] When used in a specific application environment:

[0080] First, install the welding torch on the welding torch clamp 340 of this welding auxiliary device;

[0081] As needed, place the angle steel 1 and the connecting plate 2 on the mounting bracket 100 and temporarily fix them;

[0082] Adjust the welding torch angle, height, and initial position (usually set at the longitudinal edge of the angle steel section to be welded, i.e., positioned on the straight line where multiple transverse weld initiation points are located), set various welding parameters, and then start automatic welding; the welding cycle is as follows:

[0083] The walking base 312 moves longitudinally on the walking guide rail 311. The proximity switch sweeps over each siding plate 2 and positions the siding plate 2.

[0084] The traveling mechanism 310 controls the welding torch to stop traveling after it reaches the weld seam according to the position of the gusset plate 2. Then the lifting mechanism 320 lowers the telescopic mechanism 330 to a certain height so that the welding torch contacts the weld seam and ignites the welding.

[0085] Then the telescopic mechanism 330 extends, and the welding gun moves horizontally in sync to complete the welding (transverse welding) on ​​both sides of the gusset plate 2;

[0086] The traveling mechanism 310 travels a distance equal to the width of the gusset plate 2, and the welding torch simultaneously completes the welding (longitudinal welding) at the end of the gusset plate 2.

[0087] After the telescopic mechanism 330 is raised to its original height and retracted to its original length, the traveling mechanism 310 continues to travel to weld the next piece of the gusset plate 2.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
