Description

Technical Field

[0001] This invention relates to the field of steel structure welding technology, specifically to a welding device for installing steel structure frames. Background Technology

[0002] In actual steel structure frame installation work, such as steel structure frame joints, connections are usually made by welding. A typical steel structure joint involves vertically installing another I-beam along the side of a horizontal I-beam. The upper and lower edges of the vertically installed I-beam are beveled before welding to the horizontal I-beam. Current steel structure frame welding usually requires the use of a backing plate to ensure weld quality and also to act as an arc initiator. However, in actual welding, the backing plate must be manually held and placed against the bottom of the weld for tack welding positioning. Furthermore, steel backing plates are typically used, making them inconvenient to reuse. Manually carrying the liner is a cumbersome operation, and the fit between the liner and the bottom of the weld is difficult to control, making visual inspection inaccurate. Large gaps directly affect the quality of the weld bottom formation. In addition, the liner cannot be removed after welding, making it difficult to fully paint the liner and the bottom of the steel structure I-beam for rust prevention, which affects the service life. Furthermore, the steel liner protrudes from the weld ends, which is unsightly and further increases the difficulty of painting. If ceramic patch liner is used, high-altitude welding operations are difficult, and the adhesion is not strong. In addition, ceramic liner is not convenient for workers to start the arc and weld, resulting in poor weld end formation.

[0003] Therefore, we propose a welding device for installing steel structure frames. Summary of the Invention

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1 to 12 As shown:

[0033] This invention provides a technical solution: a welding device for installing a steel structure frame, comprising a welding inner liner 1, a clamping fastener 2 installed on the welding inner liner 1 for clamping the steel structure I-beam frame; a seepage control component 3 installed on the welding inner liner 1 for maintaining weld quality; a detachable clamping component 4 installed on the welding inner liner 1, an elastic fitting component 5 installed on the detachable clamping component 4; an arc-starting auxiliary component 6 installed on the elastic fitting component 5 for fitting the steel structure I-beam frame; a welding torch connector 7 installed on the detachable clamping component 4 for mounting a welding torch to weld the steel structure I-beam frame; the welding inner liner 1 includes: an embedded frame 101 and a ceramic backing plate 102, the ceramic backing plate 102 being inserted into the embedded frame 101, and the top of the ceramic backing plate 102 being fitted to the bottom of the weld of the steel structure I-beam; an arc-shaped groove is provided in the middle of the ceramic backing plate 102.

[0034] The welded inner liner 1 further includes: detection slots 1021 and reinforcing bolts 103. Two rows of detection slots 1021 are provided on the ceramic liner 102, located on both sides of the arc-shaped groove on the ceramic liner 102. Four reinforcing bolts 103 are threaded onto the embedded frame 101 and are respectively inserted into the ceramic liner 102. The clamping fastener 2 includes: threaded cylinders 201, fastening bolts 202, and a lower pressure bracket 203. Two threaded cylinders 201 are fixedly installed on the embedded frame 101, and fastening bolts 202 are threaded onto each of the two threaded cylinders 201. Lower pressure brackets 203 are rotatably sleeved on each of the two fastening bolts 202. Two lower pressure brackets 203 are rotatably sleeved at the bottom of the lower pressure bracket 203. Each end is equipped with a rubber pad; the rubber pads at both ends of the bottom of the lower pressure frame 203 are used to press and adhere to the structural I-beam frame; the seepage control component 3 includes: a bonding block 301, a push spring 302, an electrical contact spring 303, and an electrical contact block 304. Bonding blocks 301 are slidably inserted into the two rows of detection slots 1021; push springs 302 are fixedly installed at the bottom of each of the two rows of bonding blocks 301, and the other end of the push spring 302 is connected to the inside of the detection slot 1021; electrical contact springs 303 are fixedly installed at the bottom of each of the two rows of bonding blocks 301, and the electrical contact springs 303 have an arc-shaped spring structure; electrical contact blocks 304 are fixedly installed inside each of the two rows of detection slots 1021, and the two rows of electrical contact blocks 304 are aligned with the two rows of electrical contact springs 303; When the top of the assembly 301 is flush with the ceramic liner 102, the contact spring 303 elastically fits the contact block 304. Using the anti-seepage control component 3 in conjunction with the welding inner liner 1, the gap between the ceramic liner 102 and the bottom of the weld can be detected during steel structure welding. This maintains welding quality and avoids the problem of inaccurate visual observation due to deformation of the I-beam end or the presence of obstructions. It ensures the fit of the ceramic liner 102 to the weld, guarantees the forming quality of the weld bottom, prevents leakage of molten material from the weld pool, and improves welding quality. Simultaneously, this structure can be connected in series with the welding torch power supply to ensure that welding work can only proceed normally after meeting welding standards; otherwise, the welding torch cannot be powered normally, further guaranteeing the welding quality and standardization of this structure. The anti-seepage control component... The component 3 is thoroughly and accurately inspected. Meanwhile, the clamping fastener 2 allows workers to quickly and stably perform installation work. The non-adhesive installation method is more convenient for workers to operate and avoids the problem of the traditional adhesive method being difficult to operate at heights, since the ceramic backing plate 102 needs to be installed at the bottom of the weld. If there are obstructions on the top of the ceramic backing plate 102 or the edge of the weld of the I-beam is not flat, the top of the ceramic backing plate 102 cannot be completely attached to the bottom of the weld. At this time, part of the bonding block 301 on the ceramic backing plate 102 cannot be fully pressed down. With the compression of the push spring 302, the power contact spring 303 and the power contact block 304 no longer remain attached. The corresponding welding gun cannot be operated to conduct welding, and the worker needs to make adjustments.

[0035] The detachable clamping component 4 includes: a clamping mounting block 401, a fitting bolt 402, a fitting ring frame 4021, a fitting slide shaft 403, a spring post 404, and a spring 405. Clamping mounting blocks 401 are fixedly mounted on both sides of the embedded frame 101, and the two clamping mounting blocks 401 have identical structures. Fitting bolts 402 are threaded onto each of the two clamping mounting blocks 401, and fitting ring frames 4021 are rotatably sleeved on each of the two fitting bolts 402. A fitting slide shaft 403 is fixedly installed on 4021, and two fitting slide shafts 403 are slidably inserted into the clamping mounting block 401 respectively; spring posts 404 are fixedly installed at the tails of the two fitting slide shafts 403 respectively, and the spring posts 404 are hexagonal column structures; springs 405 are respectively sleeved on the two spring posts 404; the elastic fitting component 5 includes: a fitting slide rod 501, a warning light 5011, a lower pressure plate 502, and a sliding limit plate 503, and there are two fitting slide rods 501. Two sliding rods 501 are slidably sleeved on two spring posts 404 respectively; two springs 405 are connected at both ends between the two spring posts 404 and the two sliding rods 501 respectively; a lower pressure plate 502 is fixedly installed on each of the two sliding rods 501, and the two are slidably attached to the top of the ceramic liner 102 respectively; a sliding limiting plate 503 is fixedly installed on the side of each of the two lower pressure plates 502, and the two sliding limiting plates 503 are L-shaped structures; the two sliding limiting plates 505... 03 are slidably attached to the embedded frame 101 respectively; warning lights 5011 are fixedly installed on the two attached sliding rods 501 respectively; the arc-starting auxiliary component 6 includes: ceramic block 601 and arc-starting block 602, ceramic block 601 is fixedly installed at the ends of the two lower pressure plates 502 respectively, and the ceramic block 601 is attached to the ceramic backing plate 102; the arc-starting block 602 is fixedly installed on the ceramic block 601; the width of the arc-starting block 602 is greater than the weld width; the side of the arc-starting block 602 is pressed and attached to the side of the I-beam;The arc-starting block 602 aligns with the weld seam, employing an arc-starting auxiliary component 6 in conjunction with an elastic fitting component 5. This enhances its flexibility, allowing for rapid weld seam connection and assisting workers in arc-starting operations. It eliminates the need to weld an arc-starting plate to one side of the steel structure weld, avoiding arc-starting difficulties and making it more suitable for large weld seams. Simultaneously, this structure automatically advances and flattens the weld seam end during arc-starting, improving the flatness of the weld seam end, reducing the difficulty of subsequent painting and finishing, and enhancing aesthetics. Furthermore, the flattening of the weld seam occurs as welding progresses; after the molten pool forms, the ceramic block 601 is advanced to fit the weld seam end, ensuring the arc-starting block 602 is stably clamped and used for arc-starting. The structure is simple to operate; tightening the two fitting bolts 402 drives the two fitting sliding shafts 403, causing the spring column 404 to retract, which in turn moves the lower pressure plate 502, propelling the ceramic block 601 to initiate the arc. Block 602 is pressed and adhered to the side of the vertical I-beam of the steel structure, at the end of the weld. It works in conjunction with spring 405 to press and adhere to sliding rod 501, achieving elastic clamping. During subsequent welding operations, the welding wire can be first inserted into the arc-starting block 602 to ignite the arc. At this time, as the high-temperature molten pool is generated during welding, the area where the arc-starting block 602 and the edge of the vertical I-beam are in contact also melts. The hardness of the resulting high-temperature molten pool is limited. With the help of spring 405, the sliding rod 501 can be moved, causing the ceramic block 601 to adhere to the edge of the vertical I-beam, i.e., the end of the weld, for flattening. After the molten pool is formed, the surface is smoother. When extinguishing the arc, as the welding wire moves to the arc-starting block 602 on the extinguishing side, the arc-starting block 602 will be melted. Similarly, the ceramic block 601 on the corresponding side will move inward to adhere, keeping the weld end flat. At this point, the welding wire can be quickly separated from the weld.

[0036] The arc-starting auxiliary component 6 also includes: a detection switch 603, with each of the two ceramic blocks 601 fixedly mounted with a detection switch 603, and the detection switches 603 located on the side of the I-beam; when the two arc-starting blocks 602 are pressed and adhered to the side of the I-beam, there is a gap between the two detection switches 603 and the two sides of the I-beam; the two detection switches 603 are electrically connected to two warning lights 5011 respectively. The arc-starting auxiliary component 6 can be used to remind workers that the arc-starting blocks 602 are installed correctly, preventing workers from overlooking installation and directly aligning the welding wire with the weld bevel to start the arc, thus avoiding welding errors. It provides a visual reminder and accurate detection. In actual use, the arc-starting and arc-ending can be assisted and compensated by the arc-starting blocks 602 on both sides of the weld, ensuring that the welding wire can completely pass through both ends of the weld. The arc-starting blocks 602 are positioned between the ceramic blocks 601 and the vertical side of the I-beam, as shown in the attached diagram. Figure 11At the position shown, the detection switch 603 is supported by the arc-starting block 602 and will not be in contact with the side of the vertical I-beam. Conversely, if the arc-starting block 602 is not installed, or if the arc-starting block 602 is not located outside the two ends of the weld, the ceramic block 601 will be directly in contact with the side of the vertical I-beam, and the detection switch 603 will also be pressed and in contact with the side of the vertical I-beam, controlling the warning light 5011 on the corresponding side to light up as a reminder.

[0037] In Embodiment 2, based on Embodiment 1, the welding torch connector 7 includes: a suspension wire 701 and a collar 702. One end of the suspension wire 701 is fixedly connected to the clamping mounting block 401 on the front side; the other end of the suspension wire 701 is fixedly mounted with the collar 702. The welding torch connector 7 also includes: a positioning bolt 703, with the positioning bolt 703 threaded onto the collar 702; the collar 702 is used to attach the welding torch; the end of the positioning bolt 703 is used to press and adhere to the outside of the welding torch; two rows of electrical contact springs 303, electrical contact blocks 304, the suspension wire 701, and the switch on the welding torch are connected in series for the welding machine; the ceramic liner plate 102 has openings for the electrical contact springs 303 and electrical contact blocks. The 304 series wiring holes are used to connect the suspension wires 701. The welding gun connector 7 allows the structure to be directly connected to the welding gun, preventing loss. At the same time, the structure uses a detachable and reusable ceramic backing plate 102, which is cheaper and more convenient for large-scale welding operations, improving the flexibility of use. After disassembly, the detachable ceramic backing plate 102 also makes it easy for workers to paint it, ensuring the anti-rust effect. This avoids the problem of traditional steel backing plates, where the backing plate is wider than the weld, making it difficult to fully paint the top two sides of the backing plate and the area where the weld of the I-beam is in contact with the weld, and the weld is not aesthetically pleasing. The suspension wires 701 also serve as a hanging connection.

[0038] The working principle of this embodiment is as follows: First, the welding torch is directly inserted into the collar 702 and secured by the positioning bolt 703. The ceramic backing plate 102 is then attached to the bottom of the upper or lower weld of the steel structure. The weld is then aligned with the arc-shaped groove in the middle of the ceramic backing plate 102. The mounting bolt 402 on either side can be rotated first to remove it from the detachable clamping member 4, preventing obstruction of the installation of the ceramic backing plate 102. After the ceramic backing plate 102 is inserted into the bottom of the weld, the mounting bolt 402 can be installed on the clamping mounting block 401. The fastening bolt 202 can be tightened to move the lower pressure frame 203 downward and press it against the horizontal I-beam. The steel and the vertical I-beam surface are clamped together to ensure that the top of the ceramic liner 102 is attached to the bottom of the weld. However, if there are obstructions on the top of the ceramic liner 102 or the edge of the I-beam weld is not flat, the top of the ceramic liner 102 cannot be fully attached to the bottom of the weld. In this case, part of the contact block 301 on the ceramic liner 102 cannot be fully pressed down. Combined with the pressure from the push spring 302, the electrical contact spring 303 and the electrical contact block 304 no longer maintain contact, and the corresponding welding torch cannot be operated for welding. Adjustments are required to ensure standard welding quality. This can be achieved by tightening the two contact bolts 402 separately. The two sliding shafts 403 move inward, causing the spring column 404 to retract, which in turn moves the lower pressure plate 502. This moves the ceramic block 601, pushing the arc-starting block 602 to press against the side of the vertical I-beam of the steel structure, at the weld end. The spring 405, in conjunction with the sliding rod 501, provides elastic clamping. During subsequent welding, the welding wire can be connected to the arc-starting block 602 to ignite the arc. As the high-temperature molten pool is generated during welding, the area where the arc-starting block 602 and the edge of the vertical I-beam meet is also melted. The resulting high-temperature molten pool has limited hardness; the spring 405 can then push the sliding rod 501 to move, causing the ceramic block 601 to press against the side of the vertical I-beam. Block 601 is attached to the edge of the vertical I-beam, that is, the end of the weld, for flattening work. After the molten pool is formed, the surface is smoother. When the arc is closed, the welding wire moves to the arc-starting block 602 on the arc-closing side. At this time, the arc-starting block 602 will be melted. Similarly, the ceramic block 601 on the corresponding side will also move inward to fit, keeping the end of the weld flat. At this time, the welding wire can be quickly separated from the weld. During the welding process, when the warning light 5011 is lit, it is necessary to observe whether the arc-starting block 602 is installed. If the bevel weld of the upper edge of the vertical I-beam is completed first, the same operation is performed to continue welding the bevel weld of the lower edge of the vertical I-beam.
