Description

Technical Field

[0001] This application relates to the technical field of steel jacket for beam-column, and particularly to an automatic welding device for the steel jacket process of beam-column. Background Art

[0002] In the renovation project of existing buildings, the steel jacket process for beam-column is often used. Taking the steel jacket for column as an example, in this process, four vertically arranged angle steels are installed on the four outer corners of the column, and then horizontal steel gusset plates are arranged at certain intervals in the height direction on the four sides of the column and are fillet welded to the angle steels. At present, all the welding of angle steels and gusset plates is carried out manually on site, with low efficiency, and the welding quality is difficult to control due to the uneven technical levels of the welders. Summary of the Invention

[0003] The purpose of this application is to solve the problems of low accuracy and efficiency in the automatic welding of angle steels and gusset plates in the steel jacket process for beam-column in the prior art. Therefore, this application provides an automatic welding device for the steel jacket process of beam-column. By cooperating the mounting frame, positioning components and proximity switches to position the weld area, the accuracy and efficiency of weld positioning are improved, thereby improving the welding accuracy and efficiency.

[0004] An embodiment of this application provides an automatic welding device for the steel jacket process of beam-column, which welds multiple gusset plates in the steel jacket process of the beam to the angle steel, and the corresponding welds are composed of two transverse welds and one longitudinal weld, including:

[0005] A mounting frame, including an angle steel bearing position and a gusset plate bearing position, and enabling the angle steel and the gusset plate to be located at the welding position;

[0006] Positioning components, including an angle steel positioning member and a gusset plate positioning rod arranged on the mounting frame, and the angle steel positioning member enables the angle steel to abut against the mounting frame, and the gusset plate positioning rod enables the length of each gusset plate lapping on the angle steel to be consistent with the preset length of the transverse weld;

[0007] A three-dimensional moving device and a proximity switch and two welding torches arranged thereon, the three-dimensional moving device is arranged on the mounting frame, and can drive the proximity switch to sequentially position at least one side edge position of each gusset plate, and the two welding torches to sequentially weld each gusset plate;

[0008] A controller, which is used to determine the positions of the transverse weld and the longitudinal weld according to at least one side edge position of the gusset plate, the preset length of the transverse weld and the preset length of the longitudinal weld; and control the three-dimensional moving device to drive the two welding torches to synchronously weld the two transverse welds corresponding to each gusset plate, and then weld the longitudinal weld according to the initial position of the three-dimensional moving device, the position of the transverse weld and the position of the longitudinal weld.

[0009] With the above technical solution, a welding reference is provided by the mounting bracket, thus eliminating the need for spot welding pre-fixing, improving the welding efficiency, and cooperating with the positioning components to enable the angle steel and the batten plate to be stably in the welding state. In particular, the transverse weld length is ensured to be accurate by the batten plate positioning rod, and the operation is convenient and reliable. Moreover, by the proximity switch, at least one edge position of the batten plate is sequentially positioned as the welding operation moves, so that the weld area can be positioned in cooperation with the established dimensions or positions (the preset length of the transverse weld and the preset length of the longitudinal weld), that is, the weld is positioned by one sensing data in cooperation with multiple established data, improving the positioning accuracy and efficiency, and enabling positioning while welding, thereby improving the welding accuracy and efficiency. At the same time, the three-dimensional moving device drives two welding torches to perform synchronous transverse welding, further improving the positioning efficiency and welding efficiency.

[0010] In some embodiments, the three-dimensional moving device includes:

[0011] A traveling mechanism, including a traveling guide rail disposed on the mounting bracket and parallel to the batten plate positioning rod, and a traveling base that can travel along the traveling guide rail;

[0012] A lifting mechanism, detachably connected to the traveling base through a connecting member;

[0013] A telescopic mechanism, connected to the lifting mechanism;

[0014] The welding torch is disposed on the telescopic mechanism and can move along the length direction of the batten plate with the telescopic mechanism;

[0015] The proximity switch is disposed at the bottom of the fixed seat of the lifting mechanism or the telescopic mechanism, and the lifting mechanism can adjust the distance from the angle steel through the connecting member and make the proximity switch close to the end of the overlapping position of the angle steel and the batten plate.

[0016] With the above technical solution, the three-dimensional movement of the welding torch is driven by the traveling mechanism, the lifting mechanism and the telescopic mechanism, improving the welding flexibility. Moreover, the detachable connection between the lifting mechanism and the traveling mechanism is realized through the connecting member, improving the portability of the device. At the same time, the distance between the proximity switch disposed at the bottom of the lifting mechanism and the angle steel can also be adjusted through the connecting member, so that it is located at an appropriate detection position, close to the weld, improving the weld positioning accuracy, and thus improving the welding accuracy. And this detection position is close to the transverse weld and far from the longitudinal weld. Cooperating with the welding sequence of first transverse and then longitudinal, it enables positioning during longitudinal welding and reduces the interference of high-temperature and high-brightness and other interference factors during welding on the proximity switch, ensuring the positioning accuracy.

[0017] In some embodiments, the controller controls the three-dimensional moving device to drive the two welding torches to synchronously weld two transverse welds corresponding to the gusset plate, and then weld the longitudinal weld, specifically as follows:

[0018] The controller controls the three-dimensional moving device to drive the two welding torches to synchronously move towards the longitudinal weld, so as to weld from the front end to the rear end of the transverse weld, then turn off the welding torch located at the front end of the traveling direction of the traveling base, and drive the welding torch at the rear end to move along the traveling direction, so as to weld from the front end to the rear end of the longitudinal weld.

[0019] By adopting the above technical solution, by synchronously welding the two side transverse welds from the front end to the rear end, and then welding longitudinally while moving forward, the welding efficiency is improved, and the movement control is relatively simple, the operation is reliable, and it is convenient to repeat the operation for welding multiple gusset plates.

[0020] In some embodiments, the two welding torches are detachably arranged on the mounting plate and can move synchronously with the mounting plate, and the mounting plate is connected to the telescopic mechanism;

[0021] The distance between the two welding torches is adjustable, and the welding distance corresponding to the two welding torches is adapted to the width of the gusset plate, so as to synchronously weld the transverse welds on both sides of the gusset plate.

[0022] By adopting the above technical solution, since the welding torch can be separated from the telescopic mechanism of the three-dimensional moving device, the portability of the device is improved. Moreover, since the distance between the two welding torches is adjustable, it can be adapted to gusset plates of different widths, and the versatility of the device is improved.

[0023] In some embodiments, the traveling guide rail includes a rack arranged on the top surface and limiting ridges arranged on both sides;

[0024] The traveling base includes a driving member, a gear adapted to the rack, and at least two limiting wheels respectively adapted to the two limiting ridges. Both ends of the limiting wheel are clamped with the upper and lower sides of the limiting ridge, and the limiting wheel can roll along the limiting ridge.

[0025] By adopting the above technical solution, the traveling of the traveling mechanism is realized through the gear-rack transmission, which can achieve efficient transmission, and is suitable for the relatively harsh environment at the construction site of beam-column steel casing. It has a long service life and low cost; moreover, it has high load-bearing performance and can provide a stable and reliable installation and moving platform for other parts of the three-dimensional moving device, as well as proximity switches and two welding torches.

[0026] In some embodiments, the traveling guide rail is installed on the mounting frame through a lifting member, and the lifting member is arranged on the side of the gusset plate bearing position;

[0027] The top of the lifting member is provided with a limiting groove adapted to the walking guide rail, and the walking guide rail can be embedded in the limiting groove;

[0028] The lifting member and the mounting bracket are magnetically mounted.

[0029] With the above technical solutions, a spaced space is formed between the walking guide rail and the mounting bracket through the lifting member, facilitating the placement of the gusset plate; moreover, the lifting member and the mounting bracket are installed by magnetic attraction, enabling convenient assembly and improving the overall efficiency; at the same time, the stability, reliability, and accuracy of the installation of the walking guide rail are improved through the limiting groove of the lifting member, thereby enhancing the stability, reliability, and accuracy of welding.

[0030] In some embodiments, the proximity switch is an inductive proximity switch, a reflective photoelectric switch, or a contact mechanical switch;

[0031] A detection avoidance channel is formed between each of the gusset plate bearing positions, and the detection avoidance channel is located at the end of the overlapping position of the angle steel and the gusset plate, allowing the proximity switch to pass through without being triggered.

[0032] With the above technical solutions, by using a proximity switch such as an inductive proximity switch, a reflective photoelectric switch, or a contact mechanical switch, it is suitable for the relatively harsh environment of the construction site of steel-wrapped beams and columns, and only needs to be set above the mounting bracket, facilitating assembly; moreover, by setting a detection avoidance channel at the end of the overlapping position of the angle steel and the gusset plate, the probability of false triggering is reduced, further improving the positioning accuracy.

[0033] In some embodiments, the mounting bracket is a rectangular frame assembled by a plurality of square tubes, and the intersecting two side surfaces of one of the square tubes located at the edge form the angle steel bearing position.

[0034] With the above technical solutions, the mounting bracket formed by assembling square tubes into a rectangular frame is convenient for temporary assembly in the construction environment, and can ensure the levelness and perpendicularity of the mounting bracket, thereby ensuring the accuracy of the formed angle steel bearing position and gusset plate bearing position, and improving the welding accuracy.

[0035] In some embodiments, the gusset plate positioning rod is an angle steel of the same specification as the angle steel to be welded.

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

[0051] The steel-plated beam-column process is to externally attach angle steel 1 to the outer corners of the beam-column, and then horizontally arrange steel gusset plates 2 at certain intervals on the four sides of the beam-column (this interval is not less than the width of the gusset plate 2 and is uneven, usually larger in the middle part of the angle steel and smaller at the ends, with dense arrangement), and fillet weld them to the angle steel 1. For a single gusset plate 2, the corresponding weld seam consists of two transverse welds and one longitudinal weld, which is adapted to the shape of the end edge of the gusset plate 2. In current construction, manual welding is usually carried out one by one, with a large amount of work, high construction difficulty, and it is difficult to guarantee the welding effect.

[0052] Please refer to Figures 1-4 , Figure 1 which is a schematic diagram of the usage state of the present application; Figure 2 is Figure 1 a partial enlarged structural schematic diagram of Figure 3 which is a structural schematic diagram of the present application; Figure 4 which is another structural schematic diagram of the present application.

[0053] The embodiment of the present application provides an automatic welding device for the steel-plated beam-column process, which welds a plurality of gusset plates 2 in the steel-plated beam process to the angle steel 1. The welding device includes a mounting frame 100, a positioning component, a three-dimensional moving device, a proximity switch, and a welding torch.

[0054] The mounting bracket 100 includes an angle steel bearing position and a batten bearing position, and enables the angle steel 1 and the batten 2 to be located at the welding position, that is, the front ends of multiple battens 2 can be sequentially lapped on the angle steel 1 along the length direction thereof, so as to form a U-shaped weld area composed of two transverse welds and one longitudinal weld, and this method enables the angle steel 1 and the batten 2 to be free of spot welding pre-fixation, improving the welding efficiency.

[0055] The positioning assembly includes an angle steel positioning member 210 and a batten positioning rod 220 arranged on the mounting bracket 100. The angle steel positioning member 210 enables the angle steel 1 to abut against the mounting bracket 100 to ensure the stability of the angle steel 1 during the welding process. The batten positioning rod 220 enables the overlapping length of each batten 2 on the angle steel 1 to be consistent with the preset length of the transverse weld, thereby ensuring the accuracy of the transverse welding length. Preferably, the batten positioning rod 220 is arranged at the rear end of the batten bearing position and abuts against the rear end of the batten 2, so that the overlapping length of the batten 2 and the angle steel 1 can be determined when the batten 2 is placed, and the operation is convenient. Further, to ensure the levelness of the batten 2, the batten 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 batten 2 overlap on the angle steel 1, that is, one limb part of the angle steel 1 serving as the batten positioning rod 220 bears the batten, and the other limb part abuts against the end of the batten, and this method is convenient for obtaining materials and is especially suitable for the construction environment. The batten positioning rod 220 can also be a magnetic block, so as to facilitate fixing with the mounting bracket.

[0056] There are two welding torches, and the proximity switch and the two welding torches are both arranged on the three-dimensional moving device. The three-dimensional moving device is arranged on the mounting bracket 100 and can drive the proximity switch to sequentially position at least one side edge position of each batten 2, that is, identify the actual position of the batten 2 distributed longitudinally along the angle steel 1, and drive the two welding torches to sequentially weld each batten 2. The welding torch preferably adopts a welding torch with automatic wire feeding, so as to facilitate automatic welding.

[0057] The controller is used to determine the positions of the transverse weld and the longitudinal weld according to at least one side edge position of the batten 2, the preset length of the transverse weld and the preset length of the longitudinal weld; and control the three-dimensional moving device to drive the two welding torches to synchronously weld the two transverse welds of the corresponding batten 2 and then weld the longitudinal weld according to the initial position of the three-dimensional moving device, the position of the transverse weld and the position of the longitudinal weld.

[0058] Preferably, the initial position of the three-dimensional moving device can be set so that the welding torch is aligned with the starting point of the transverse weld of the first batten, or the welding torch is aligned with the longitudinal edge of the limb part of the angle steel to be welded, so as to simplify the movement control of the three-dimensional moving device by the controller.

[0059] It should be noted that the angle steel 1 and the batten plate 2 are standard parts with several standard specifications. At the same time, in the process of steel casing for beam-column, the welding standards for angle steel 1 and batten plate 2 of different specifications are also determined, that is, the lengths of the horizontal and vertical welds have standards.

[0060] This method positions at least one side edge position of the batten plate 2 in sequence through the movement of the proximity switch along with the welding operation, so as to cooperate with the established dimensions (the preset length of the horizontal weld and the preset length of the vertical weld, and of course, the preset lengths of the horizontal and vertical welds can also be determined according to the dimensions of the angle steel 1 and the batten plate 2) to position the weld area, that is, to achieve weld positioning by means of one detection data in combination with multiple established data, improving the positioning accuracy and efficiency, and enabling positioning while welding, thus improving the welding accuracy and efficiency.

[0061] At the same time, the three-dimensional moving device drives two welding torches to perform horizontal welding synchronously, further improving the positioning efficiency and welding efficiency.

[0062] Moreover, it should also be noted that to ensure the welding quality, the welding angle is crucial. When a single welding torch welds this U-shaped weld, the first horizontal seam and the vertical seam usually can adopt the same angle, but the second horizontal seam is symmetrical with the first horizontal seam, and its welding angle also needs to be symmetrical, that is, the welding torch needs to be rotated significantly when welding the second horizontal seam.

[0063] However, after this device adopts two welding torches to perform horizontal welding synchronously and then vertical welding, that is, the two welding torches can synchronously extend outward to symmetrically weld two horizontal seams, and then move forward to weld the vertical seam (the previous welding torch stops working automatically as it moves forward and detaches from the workpiece (batten plate), and the latter welding torch continues to work while continuously contacting the workpiece), so that there is no need to adjust the welding torch angle, thus simplifying the welding torch connection structure, controlling the overall weight, volume and cost of the device, and at the same time simplifying the movement control of the welding torch.

[0064] In one embodiment, the three-dimensional moving device includes a traveling mechanism 310, a lifting mechanism 320 and a telescopic mechanism 330 to drive the welding torch to move three-dimensionally, improving the welding flexibility.

[0065] The traveling mechanism 310 includes a traveling guide rail 311 arranged on the mounting frame 100 and parallel to the batten plate positioning rod 220, and a traveling base 312 that can travel along the traveling guide rail 311.

[0066] The lifting mechanism 320 is detachably connected to the traveling base 312 through a connecting member 314.

[0067] The telescopic mechanism 330 is connected to the lifting mechanism 320, that is, the lifting mechanism 320 and the traveling mechanism 310 can be separated through the connecting member 314, improving the portability of the device.

[0068] The welding gun is arranged on the telescopic mechanism 330 and can move along the length direction of the gusset plate 2 with the telescopic mechanism 330 to realize transverse welding, and realizes longitudinal welding through the walking mechanism 310.

[0069] The proximity switch is arranged at the bottom of the fixed seat of the lifting mechanism 320 or the telescopic mechanism 330, and the lifting mechanism 320 can adjust the distance from the angle steel 1 through the connecting piece 314, and make the proximity switch close to the end of the overlap position of the angle steel 1 and the gusset plate 2, that is, the position indicated by the arrow A in the figure, so that the proximity switch is located at the appropriate detection position, close to the weld, to improve the accuracy of weld positioning, and then improve the welding accuracy. In addition, the detection position is close to the transverse weld, but far away from the longitudinal weld, and with the welding sequence of first transverse and then longitudinal, the movement of the longitudinal welding can be positioned at the same time, making the various parts of the device compact, controlling the overall volume, and reducing the interference of interference factors such as high temperature and high brightness of welding on the proximity switch, ensuring the accuracy of positioning.

[0070] It is understandable that when the proximity switch is adjusted to a proper inspection position, it only moves longitudinally with the traveling mechanism 310 , but does not move up and down with the lifting mechanism 320 or move laterally with the telescopic mechanism 330 .

[0071] In one embodiment, the controller controls the three-dimensional mobile device to drive two welding guns to synchronously weld the two transverse welds of the corresponding gusset plate 2, and then weld the longitudinal weld, as follows:

[0072] The controller controls the three-dimensional mobile device to drive the two welding guns to move synchronously toward the longitudinal weld seam, so as to weld from the front end of the transverse weld seam to its rear end, and then close the welding gun at the front end of the walking direction of the walking base 312, and drive the welding gun at the rear end to move along the walking direction, so as to weld from the front end of the longitudinal weld seam to its rear end. That is, the transverse weld seams on both sides are welded synchronously from the front end to the rear end, and then the turning is carried out in accordance with the rotation. By moving forward and welding longitudinally at the same time, the welding efficiency is improved, and the movement control is relatively simple, the operation is reliable, and it is convenient to weld and repeat the operation of multiple gusset plates 2.

[0073] In one embodiment, two welding guns are detachably mounted on a mounting plate and can move synchronously with the mounting plate, and the mounting plate is connected to the telescopic mechanism 330. Preferably, two welding gun fixtures 340 (only one is shown in the figure) are arranged on the mounting plate, and the welding guns are detachably mounted on the mounting plate through the welding gun fixtures 340, and during construction, the welding guns can be fixed at an angle, etc., according to specific welding requirements through the welding gun fixtures 340, so as to further improve the welding accuracy. In addition, the welding guns are detachable from the mounting plate, that is, the welding guns are separable from the telescopic mechanism 330 of the three-dimensional mobile device, which improves the portability of the device.

[0074] In one embodiment, the distance between the two welding torches is adjustable, and the welding distances corresponding to the two welding torches are adapted to the width of the gusset plate 2, so as to synchronously weld the transverse welds on both sides of the gusset plate 2. By making the distance between the two welding torches adjustable, gusset plates 2 with different widths (i.e., different longitudinal weld lengths) can be adapted, improving the versatility of the device.

[0075] In one embodiment, the walking guide rail 311 includes a rack provided on the top surface, and the walking base 312 includes a driving member and a gear adapted to the rack. The walking mechanism 310 walks through the gear-rack transmission, which can achieve efficient transmission, is suitable for the relatively harsh environment of the steel-sheathed beam-column construction site, has a long service life and low cost; and has high load-bearing performance, and can provide a stable and reliable installation and moving platform for other parts of the three-dimensional moving device, proximity switches, and two welding torches.

[0076] Moreover, since the length of the angle steel 1 adapted to the cross beam in the steel-sheathed beam-column process is usually very long, the corresponding walking guide rail 311 is relatively long. For the convenience of transporting and carrying the device, the walking guide rail 311 can be composed of multiple sections spliced together, and the gear-rack transmission is also convenient for splicing the walking guide rail 311. To optimize the welding effect, the splicing position of the walking guide rail 311 should avoid the orthographic projection plane of the gusset plate 2.

[0077] In one embodiment, limiting ridges are further provided on both sides of the walking guide rail 311, and the walking base 312 includes at least two limiting wheels adapted to the two limiting ridges one by one. Both ends of the limiting wheels are clamped with the upper and lower sides of the limiting ridges, and the limiting wheels can roll along the limiting ridges, thereby improving the stability and reliability of the connection between the walking base 312 and the walking guide rail 311, and having a small volume and convenient assembly.

[0078] In one embodiment, the walking guide rail 311 is installed on the mounting frame 100 through a lifting member 313, and the lifting member 313 is arranged on the side of the gusset plate bearing position, that is, there is an interval space between the walking guide rail 311 and the mounting frame 100 through the lifting member 313, so as to facilitate the placement of the gusset plate 2.

[0079] In one embodiment, the lifting member 313 and the mounting frame 100 are magnetically installed, which is convenient for assembly and improves the overall efficiency.

[0080] In one embodiment, a limiting groove adapted to the walking guide rail 311 is provided at the top of the lifting member 313, and the walking guide rail 311 can be embedded in the limiting groove. The stability, reliability and accuracy of the installation of the walking guide rail 311 are improved through the limiting groove of the lifting member 313, thereby improving the welding stability, reliability and accuracy.

[0081] 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 relatively harsh environment of the steel-plated construction site of beams and columns, and only needs to be installed above the mounting frame 100, which is convenient for assembly. The inductive proximity switch and the reflective photoelectric switch are convenient to assemble and have accurate positioning; while the contact mechanical switch 400 has a lower cost, but usually includes a rotatable cantilever wheel for contacting the gusset plate 2. On the one hand, the size of the cantilever wheel is relatively large, which requires a higher distance between the gusset plates 2. On the other hand, the cantilever wheel needs to rotate frequently during the detection process, and its service life and reliability are difficult to guarantee.

[0082] In one embodiment, a detection avoidance channel 110 is formed between each gusset plate bearing position. The detection avoidance channel 110 is located at the end of the overlapping position of the angle steel 1 and the gusset plate 2, and allows the proximity switch to pass through without triggering, thereby reducing the probability of false triggering and further improving the positioning accuracy.

[0083] In one embodiment, the mounting frame 100 is a rectangular frame assembled by a plurality of square tubes, and the intersecting sides of one square tube located at the edge form an angle steel bearing position, which is convenient for temporary assembly and size expansion at any time in the construction environment, and can ensure the levelness and verticality of the mounting frame 100, thereby ensuring the accuracy of the formed angle steel bearing position and gusset plate bearing position, and improving the welding accuracy.

[0084] During use:

[0085] First, assemble the mounting frame 100, the three-dimensional moving device, the welding torch, etc. to complete the assembly of the welding device;

[0086] Place the angle steel 1 and the gusset plate 2 on the mounting frame 100 and fix them temporarily as needed;

[0087] Start the controller, adjust the angle, height, and initial position of the welding torch (usually set at the longitudinal edge of the limb of the angle steel to be welded, that is, positioned on the straight line where the starting points of multiple transverse welds are located), set various welding parameters, and then start automatic welding; the welding cycle process is as follows:

[0088] The three-dimensional moving device moves longitudinally along the walking guide rail 311, and after the proximity switch sweeps over each gusset plate 2, it transmits the position of the gusset plate 2 to the controller;

[0089] The controller controls the welding torch to reach the weld and then pauses walking according to the position of the gusset plate 2. Then the lifting mechanism 320 descends to make the telescopic mechanism 330 reach a certain height, so that the welding torch contacts the weld and starts welding;

[0090] Then the controller controls the telescopic mechanism 330 to extend, and the welding torch synchronously moves horizontally to complete the welding on both sides of the gusset plate 2 (transverse welding);

[0091] The controller starts the traveling mechanism 310 to travel a distance equal to the width of the splicing plate 2, and the welding torch synchronously completes the welding of the end of the splicing plate 2 (longitudinal welding).

[0092] After the telescopic mechanism 330 is lifted to the original height and retracted to the original length, the traveling mechanism 310 continues to travel to weld the next splicing plate 2.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
