Description

Technical Field

[0001] This invention belongs to the field of welding equipment technology, and particularly relates to a welding device for steel structure processing. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, columns, and trusses made of shaped steel and steel plates, and undergo rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Steel structures are typically connected by welding. Due to their light weight and simple construction, they are widely used in large factories, stadiums, and high-rise buildings.

[0003] Existing welding equipment for steel structure processing uses two ring plates to enclose the welding area when welding metal steel. The welding rod on the welding machine is then inserted between the two ring plates to weld the metal steel. This prevents the sparks generated during welding from splashing outwards, thus protecting the eyes of personnel. Furthermore, the fumes generated during welding are collected between the two ring plates and can be completely removed by a suction fan, preventing the fumes from harming the health of personnel.

[0004] Although existing welding equipment has achieved effective sealing of steel structures through the ring plate structure and successfully absorbed the fumes generated during welding, the spattered welding slag tends to adhere to the inner wall of the ring plate in actual operation. The arc-shaped design of the ring plate causes this welding slag to be guided to accumulate in the gap at the bottom of the two ring plates. This not only increases the difficulty of cleaning, but may also interfere with the normal rotation of the ring plate, thereby affecting its sealing performance.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a welding device for steel structure processing to overcome the shortcomings in current practical applications. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a welding device for steel structure processing to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A welding device for steel structure processing includes a main body, a device base fixed on the main body, a main control console fixed on one side of the main body, welding hydraulic components and a welding torch mounted on the main control console, rotating clamping mechanisms symmetrically mounted at both ends of the device base, and a moving mechanism connected to the two rotating clamping mechanisms mounted on the device base. The device also includes: The degassing and slag-removing mechanism includes a fixed base, an arc-shaped cover plate one, an arc-shaped cover plate two, a degassing component, a control component, a slag-removing component, an inlet, and a groove.

The second control gear meshes with the main gear. An arc-shaped cover plate is coaxially mounted on one side of the second control gear. A control gear one is rotatably mounted on a fixed base. The control gear one meshes with a control gear two. An arc-shaped cover plate one is coaxially mounted on one side of the control gear one.

[0010] As a further technical solution of the present invention, the slag removal component includes: A slag-cleaning seat is slidably mounted on a fixed base and located between an arc-shaped cover plate one and an arc-shaped cover plate two. The two sides of the slag-cleaning seat are intermittently engaged with the grooves on the arc-shaped cover plate one and the arc-shaped cover plate two, respectively. A slide is provided at the bottom of the slag-cleaning seat. An upper slider and a lower slider are installed in the slide rail. The upper slider and the lower slider are connected as a whole, and the upper slider and the lower slider, which are connected as a whole, are fixedly connected to the slag removal seat. A rotating shaft is rotatably mounted on a fixed base, one end of which is connected to a transmission component; A rotating roller is concentrically fixed on a rotating shaft, one end of which passes through an upper slider and a lower slider, and a spiral guide groove is formed on the surface of the rotating roller; A sliding column is fixed on the inner wall of the upper slider, and the sliding column is in sliding engagement with the spiral guide groove.

[0011] As a further technical solution of the present invention, the slag removal seat and the slide are manufactured by integral molding, and one end of the slag removal seat is set as an arc plate structure with the same curvature as the arc of the first arc cover plate and the second arc cover plate.

[0012] As a further technical solution of the present invention, the rotating clamping mechanism includes: A base 1 is arranged around the degassing and slag removal mechanism and at both ends of the device platform, and both base 1 are connected to the moving mechanism; Base 2 is fixed on base 1; A clamping assembly located between base one and base two, wherein the clamping assembly is rotatably connected to base one and base two respectively, and the clamping assemblies on the two bases one are interconnected by a linkage. A rotating assembly fixed on a base two, the rotating assembly being connected to a clamping assembly located on the same base two.

[0013] As a further technical solution of the present invention, the clamping assembly includes: A rotating sleeve located between base one and base two and rotatably connected to base one and base two respectively; The clamping hydraulic components are circumferentially distributed on the rotating sleeve, and the output ends of the plurality of clamping hydraulic components are all facing the axis of the rotating sleeve, and the output ends of the plurality of clamping hydraulic components are all equipped with clamps for clamping the steel structure.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The arc-shaped cover plate 1, arc-shaped cover plate 2, degassing component, control component, and slag removal component in the degassing and slag removal mechanism work together and are linked. When arc-shaped cover plate 1 and arc-shaped cover plate 2 are in a V-shaped open position, the slag removal component is released from the bottom gap of the two and withdraws to the outside of one side of the two. This not only makes it convenient for workers to quickly clean the welding slag collected by the slag removal component, but also prevents welding slag from falling between arc-shaped cover plate 1 and arc-shaped cover plate 2 during the cleaning process. It also makes it convenient for workers to quickly and effectively clean the gap at the bottom of arc-shaped cover plate 1 and arc-shaped cover plate 2, further ensuring the cleanliness between arc-shaped cover plate 1 and arc-shaped cover plate 2, extending the service life of arc-shaped cover plate 1 and arc-shaped cover plate 2, and reducing the risk of failure caused by welding slag accumulation. During the process of sealing the steel structure with arc-shaped cover plate one and arc-shaped cover plate two, it is ensured that the slag removal component can restore the seal of the bottom gap of both and achieve rapid collection of spattered welding slag, effectively preventing welding slag from seeping into the gap at the bottom of both. Furthermore, through the bidirectional arc design of arc-shaped cover plate one and arc-shaped cover plate two, both can quickly guide the welding slag that splashes onto their inner walls to the slag removal component, improving the efficiency and quality of welding slag collection by the slag removal component. This not only enables rapid collection of welding slag, facilitating centralized processing by staff later, but also prevents welding slag from falling between arc-shaped cover plate one and arc-shaped cover plate two, ensuring that arc-shaped cover plate one and arc-shaped cover plate two can work normally without being affected by welding slag, extending the service life of arc-shaped cover plate one and arc-shaped cover plate two, and also reducing the number of maintenance and cleaning operations for arc-shaped cover plate one and arc-shaped cover plate two.

Detailed Implementation

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0031] like Figures 1 to 9 As shown, a welding device for steel structure processing provided in one embodiment of the present invention includes a device body 100, a device base 200 fixed on the device body 100, a main control console 300 fixed on one side of the device body 100, a welding hydraulic component 600 mounted on the main control console 300, a welding torch 700 mounted on the output end of the welding hydraulic component 600, the welding torch 700 being located directly above the device base 200, and rotating clamping mechanisms 500 symmetrically mounted at both ends of the device base 200. The rotating clamping mechanisms 500 can not only clamp the steel structure but also drive the clamped steel structure to rotate, thus ensuring that the welding torch 700 can complete the irregular welding of the steel structure, expanding the practicality of the welding device. A moving mechanism connected to the two rotating clamping mechanisms 500 is mounted on the device base 200. The moving mechanism can change the horizontal welding position of the steel structure through the two rotating clamping mechanisms 500 to meet diverse welding needs of the steel structure. The device also includes: The degassing and slag-removing mechanism 400 includes a fixed base 410, an arc-shaped cover plate 420, an arc-shaped cover plate 430, a degassing component 440, a control component 450, a slag-removing component 460, an inlet 470, and a groove 480. The fixed base 410 is located between two rotating clamping mechanisms 500 and fixed on the device base 200, and is located directly below the welding torch 700. The arc-shaped cover plate 420, the arc-shaped cover plate 430, and the control component 450 are respectively mounted on the fixed base 410. The control component 450 is located at one end of the fixed base 410 and is connected to the first arc-shaped cover plate 420, the arc-shaped cover plate and the cleaning component 460 respectively. The first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 are symmetrically arranged on the fixed base 410, and the arc-shaped bending direction on the first arc-shaped cover plate 420 corresponds to the arc-shaped bending direction on the second arc-shaped cover plate 430. That is, the arc-shaped orientations of the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 are close to each other and form a symmetrical opposing bending structure. The slag removal component 460 is located between the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 and is intermittently engaged with the grooves 480 opened on the inner walls of the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 respectively. The top end faces of the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 that are close to each other are provided with inlets 470 for the welding torch 700 to enter. The space enclosed by the first arc-shaped cover plate 420, the arc-shaped cover plate and the slag removal component 460 can intercept and collect the spatter generated by the welding torch 700 during welding. The arc-shaped cover plate 430 has a mounting hole on one side that is connected to the degassing component 440. One end of the degassing component 440 is located outside the arc-shaped cover plate 430 and is connected to its internal space through the mounting hole. The other end of the degassing component 440 is installed inside the main control panel 300. In the initial state, the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 are in a V-shaped open position, which allows the steel structure to enter smoothly between them and provides sufficient control space for the placement of the steel structure. At the same time, the slag removal component 460 is located on one side of the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430. When the steel structure is positioned between the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430, the control component 450 simultaneously drives the first arc-shaped cover plate 420, the second arc-shaped cover plate 430 and the slag removal component 460 to work, so that the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 rotate towards each other and achieve interference-free closure. The slag removal component 460 slides on the fixed seat 410 towards the direction of the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430, and can seal the bottom of the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 by cooperating with the groove 480, effectively preventing welding slag from seeping into the gap at the bottom of the two. During the welding process of the welding torch 700 within the arc-shaped cover plate 1 420 and arc-shaped cover plate 2 430 while welding the steel structure, the slag removal component 460 can collect the spattered welding slag. The bidirectional arc design of the arc-shaped cover plate 1 420 and arc-shaped cover plate 2 430 allows them to quickly guide the welding slag that splashes onto their inner walls to the slag removal component 460, improving the efficiency and quality of slag collection. This not only enables rapid collection of welding slag for convenient later centralized processing by staff, but also prevents welding slag from falling between the arc-shaped cover plate 1 420 and arc-shaped cover plate 2 430, ensuring that the arc-shaped cover plate 1 420 and arc-shaped cover plate 2 430 can operate normally without being affected by welding slag, extending their service life, and reducing the frequency of maintenance and cleaning of the arc-shaped cover plate 1 420 and arc-shaped cover plate 2 430. Meanwhile, the arc-shaped cover plate 1 420 and the arc-shaped cover plate 2 430 can also temporarily intercept the gas generated during welding by the welding torch 700, causing it to remain inside the arc-shaped cover plate 1 420 and the arc-shaped cover plate 2 430 for a period of time. This allows the degassing component 440 to effectively and quickly absorb and purify the gas, optimizing the welding environment. This not only reduces the risk of weld oxidation and improves the welding strength of the steel structure, but also prevents workers from inhaling the gas, ensuring the personal safety of the workers. After the steel structure welding is completed, the control component 450 reverses its operation and simultaneously drives the arc-shaped cover plate 1 420, arc-shaped cover plate 2 430, and slag removal component 460 to reverse their operation. This causes the arc-shaped cover plate 1 420 and arc-shaped cover plate 2 430 to rotate in opposite directions and return to their V-shaped open posture, allowing the steel structure inside them to be fully exposed. At this time, the slag removal component 460 moves away from the arc-shaped cover plate 1 420 and arc-shaped cover plate 2 430, and moves to one side of the arc-shaped cover plate 1 420 and arc-shaped cover plate 2 430, releasing the gap at the bottom of the arc-shaped cover plate 1 420 and arc-shaped cover plate 2 430. The enclosure not only facilitates the quick cleaning of welding slag collected by the slag removal component 460, but also prevents welding slag from falling between the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 during the cleaning process. Furthermore, it allows for quick and effective cleaning of the gaps at the bottom of the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430, further ensuring the cleanliness between them, extending their service life, and reducing the risk of failure due to welding slag accumulation.

[0032] In a preferred embodiment, the moving mechanism is preferably a mechanical structure composed of components such as a motor and a lead screw. Since the moving structure composed of components such as a motor and a lead screw is a conventional structure, it is not specifically described in this invention. According to actual production needs, any moving structure that meets the usage conditions can be freely selected, and it is not limited to the moving structure described above. The inner walls of the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 can be coated with a high-hardness slag-removing coating. This not only prevents the retention of welding slag, but also allows the welding slag that splashes onto its surface to be quickly guided away, thereby improving the slag collection efficiency of the slag removal component 460.

[0033] like Figures 3 to 8 As shown, in a preferred embodiment of the present invention, the degassing assembly 440 includes branch pipes 441, main pipe 442, connecting hose 443, suction pump and gas filter. The branch pipes 441 are equidistantly distributed on the outside of the arc-shaped cover plate 430 along the axial direction of the arc-shaped cover plate 430 and are connected to the mounting holes. One end of each of the branch pipes 441 is fixedly connected to the main pipe 442. One end of the main pipe 442 is connected to the suction pump installed in the main control panel 300 through the connecting hose 443. The output end of the suction pump is connected to the gas filter also installed in the main control panel 300. During the welding process of steel structures using the welding torch 700, welding gases are generated. Some of these gases contain toxic substances, so they need to be absorbed and treated in a timely manner to prevent them from spreading into the atmosphere and threatening the safety of workers. The suction pump draws in the gases that are temporarily trapped inside the arc-shaped cover plate 420 and arc-shaped cover plate 430. The gases then pass through the branch pipe 441, main pipe 442, and connecting hose 443 into the suction pump. The suction pump then directs the gases into the gas filter, which processes the gases. This allows the degassing component 440 to effectively and quickly absorb and purify the gases, optimizing the welding environment. This not only reduces the risk of weld oxidation and improves the welding strength of the steel structure but also prevents workers from inhaling the gases, ensuring their safety.

[0034] In a preferred embodiment, the suction pump preferably employs a negative pressure suction method; The gas filter preferably uses a filter element composed of a metal filter screen and activated carbon. Other filter materials that meet the filtration requirements can also be added to achieve multi-stage filtration of the gas and improve the filtration quality.

[0035] like Figures 3 to 8As shown, in a preferred embodiment of the present invention, the control component 450 includes a motor 451, a main gear 452, a transmission component 453, a control gear 454, and a control gear 455. The motor 451 is fixed to one side of the fixed base 410. The main gear 452 and the transmission component 453 are sequentially installed on the output end of the motor 451. One end of the transmission component 453 is connected to the slag cleaning component 460. The main gear 452 meshes with the control gear 455, which is rotatably mounted on the fixed base 410. An arc-shaped cover plate 430 is coaxially mounted on one side of the control gear 455. The control gear 454 is rotatably mounted on the fixed base 410 and meshes with the control gear 455. An arc-shaped cover plate 420 is coaxially mounted on one side of the control gear 454. When the steel structure is positioned between the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430, the first motor 451 simultaneously drives the main gear 452 and the transmission component 453 to rotate. The main gear 452 drives the second control gear 455 to rotate, and the second control gear 455 simultaneously drives the first control gear 454 and the second arc-shaped cover plate 430 to rotate. The control gear drives the first arc-shaped cover plate 420 to rotate, so that the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 rotate towards each other and achieve interference-free closure. The transmission component 453, through rotation and cooperation with the fixed seat 410, can drive the slag cleaning component 460 to slide on the fixed seat 410 towards the direction close to the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430. This allows the slag cleaning component 460 to seal the bottom of the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 by cooperating with the groove 480, effectively preventing welding slag from seeping into the gap at the bottom of the two. After the steel structure welding is completed, motor 451 reverses its operation and simultaneously drives arc-shaped cover plate 420, arc-shaped cover plate 430, and slag removal assembly 460 to reverse their operation. This causes arc-shaped cover plate 420 and arc-shaped cover plate 430 to rotate in opposite directions and return to their V-shaped open posture, allowing the steel structure inside them to be fully exposed. Meanwhile, slag removal assembly 460 moves away from arc-shaped cover plate 420 and arc-shaped cover plate 430 and moves to one side of arc-shaped cover plate 420 and arc-shaped cover plate 430, releasing the seal on the bottom gap of arc-shaped cover plate 420 and arc-shaped cover plate 430.

[0036] In a preferred embodiment, the transmission component 453 preferably adopts a transmission structure consisting of a synchronous pulley and a synchronous belt.

[0037] like Figures 3 to 9As shown, in a preferred embodiment of the present invention, the slag cleaning assembly 460 includes a slag cleaning seat 461, a slide rail 462, an upper slide block 463, a lower slide block 464, a sliding column 465, a rotating roller 466, a spiral guide groove 467, and a rotating shaft 468. The slag cleaning seat 461 is slidably mounted on the fixed seat 410 and located between the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430. The two sides of the slag cleaning seat 461 intermittently engage with the grooves 480 on the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430, respectively. The bottom of the slag cleaning seat 461 is provided with a slide rail 462, in which the upper slide block 463 and the lower slide block 464 are installed. Block 464, the upper slider 463 and the lower slider 464 are connected as a whole by bolts, and the upper slider 463 and the lower slider 464 connected as a whole are fixedly connected to the slag cleaning seat 461 by bolts. The rotating shaft 468 is rotatably mounted on the fixed seat 410, and one end of the rotating shaft 468 is connected to the transmission component 453. A rotating roller 466 is concentrically fixed on the rotating shaft 468. One end of the rotating roller 466 passes through the upper slider 463 and the lower slider 464. A spiral guide groove 467 is opened on the surface of the rotating roller 466. The spiral guide groove 467 slides in cooperation with the sliding column 465 fixed on the inner wall of the upper slider 463. The slag removal seat 461 and the slide rail 462 are preferably manufactured using an integral molding process, which can improve the overall strength of both and thus extend the service life of the slag removal seat 461 and the slide rail 462. Furthermore, one end of the slag removal seat 461 is set as an arc plate structure with the curvature of the arc-shaped cover plate 420 and the arc-shaped cover plate 430, which can further improve the efficiency of the slag removal seat 461 in collecting welding slag. At the same time, it also facilitates better matching of the two sides of one end of the slag removal seat 461 with the groove 480, reducing the size of the gap between them and improving the quality of welding slag collection by the slag removal seat 461. The fixed base 410 restricts the movement of the slag-cleaning seat 461, allowing it to move horizontally only on the fixed base 410. This restricts the rotational movement of the upper slider 463 and lower slider 464, limiting them to horizontal movement only with the slag-cleaning seat 461. The transmission component 453, through rotation and its engagement with the fixed base 410, drives the rotating shaft 468 to rotate. The rotating shaft 468 drives the rotating roller 466 and its spiral guide groove 467 to rotate. The spiral guide groove 467, through rotation and its engagement with the sliding column 465, drives the upper slider 463 and lower slider 464 to move horizontally. The slider 463 and the lower slider 464 can drive the slag removal seat 461 to move horizontally on the fixed seat 410, thereby releasing or restoring the sealing of the bottom of both the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430. This not only effectively prevents welding slag from seeping into the gap at the bottom of both, extending the service life of the first arc-shaped cover plate 420 and the arc-shaped cover plate, but also makes it convenient for workers to clean the welding slag on the slag removal seat 461, preventing welding slag from falling between the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430, ensuring that the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 can work normally without being affected by welding slag.

[0038] In a preferred embodiment, the number of spiral turns of the spiral guide groove 467 can be adaptively adjusted according to the transmission ratio of the transmission component 453, so that while the arc-shaped cover plate 1 420 and the arc-shaped cover plate 2 430 restore or release their V-shaped open posture, the slag cleaning seat 461 can move synchronously to the bottom or outside of the arc-shaped cover plate 1 420 and the arc-shaped cover plate 2 430, thereby realizing the mutual linkage of the slag cleaning seat 461, the arc-shaped cover plate 1 420 and the arc-shaped cover plate 2 430.

[0039] like Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, in a preferred embodiment of the present invention, the rotary clamping mechanism 500 includes a base 1 510, a base 2 520, a clamping assembly 530, a linkage 540, and a rotary assembly 550. The base 1 510 is respectively disposed at both ends of the device platform 200 around the degassing and slag removal mechanism 400 and is connected to the moving mechanism. The base 2 520 is fixed on the base 1 510. The clamping assembly 530 is located between the base 1 510 and the base 2 520 and is rotatably connected to the base 1 510 and the base 2 520 respectively. The clamping assemblies 530 on the two bases 1 510 are connected to each other through the linkage 540. The rotary assembly 550 is fixed on one base 2 520 and connected to one of the clamping assemblies 530 thereon.

[0040] Two clamping components 530 can center or effectively clamp the two ends of the steel structure. The rotating component 550 drives one clamping component 530 to rotate on the base 1 510 and the base 2 520. One clamping component 530 drives the other clamping component 530 to rotate synchronously through the linkage 540. The two clamping components 530 can drive the steel structure to rotate by rotating, so that the welding torch 700 can complete the irregular welding of the steel structure, meet the diverse welding needs of the steel structure, and improve the welding efficiency and welding quality of the welding device.

[0041] In a preferred embodiment, both the first base 510 and the second base 520 are concentric with the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430; The linkage 540 preferably adopts a columnar structure with telescopic function. Through its telescopic function, it ensures that the linkage 540 can effectively maintain the stable connection of the two clamping components 530 when the distance between the two bases 510 changes, and ensures that the two clamping components 530 can rotate synchronously.

[0042] like Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, in a preferred embodiment of the present invention, the clamping assembly 530 includes a rotating sleeve 531, clamping hydraulic components 532, a clamp 533, an arc-shaped rack 534, and a linkage gear 535. The rotating sleeve 531 is located between a first machine base 510 and a second machine base 520 and is rotatably connected to both machine bases 510 and 520 respectively. The rotating sleeve 531 is circumferentially distributed with clamping hydraulic components 532, and the output ends of the plurality of clamping hydraulic components 532 all face the axis of the rotating sleeve 531. Furthermore, each of the output ends of the multiple clamping hydraulic components 532 is equipped with a clamp 533 for clamping the steel structure. An arc-shaped rack 534 is also fixed on the outer wall of the rotating sleeve 531. One side of the arc-shaped rack 534 meshes with a linkage gear 535 rotatably mounted on the machine base 2 520, and the other side of the arc-shaped rack 534 meshes with a rotating assembly 550. The two linkage gears 535 located on the two machine bases 2 520 are concentrically and fixedly connected by a linkage component 540. Initially, the distances of multiple clamps 533 from the axis of the rotating sleeve 531 are all the same. Multiple clamping hydraulic components 532 can drive multiple clamps 533 to move synchronously toward the steel structure through synchronous extension and retraction, thereby completing the centering clamping of the steel structure. Alternatively, multiple clamping hydraulic components 532 can drive multiple clamps 533 to move intermittently toward the steel structure through individual extension and retraction, thereby achieving stable clamping of irregularly shaped steel structures. By controlling multiple clamping hydraulic components 532, the clamps 533 can stably clamp steel structures of different specifications, meeting the fixing requirements of the steel structure, and improving the welding efficiency and welding quality of the steel structure.

[0043] In a preferred embodiment, both the clamping hydraulic component 532 and the welding hydraulic component 600 preferably adopt a hydraulic drive structure consisting of a hydraulic telescopic cylinder and a telescopic rod, but other drive structures that meet the usage requirements can also be adopted.

[0044] like Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, in a preferred embodiment of the present invention, the rotating assembly 550 includes a second motor 551, a main shaft 552, and a rotating gear 553. The second motor 551 is fixed on a second base 520. The main shaft 552 is fixed on the output end of the second motor 551. The rotating gear 553, which meshes with the arc-shaped rack 534 located on the same second base 520, is fixed on the main shaft 552.

[0045] When the welding torch 700 needs to perform irregular welding on the steel structure, the rotating component 550 drives the rotating sleeve 531 located at one end of the device base 200 to rotate through the arc rack 534. The arc rack 534 drives the linkage gear 535 to rotate, and the linkage gear 535 drives the linkage gear 535 located at the other end of the device base 200 to rotate through the linkage component. This allows the rotating sleeves 531 located at both ends of the device base 200 to rotate. The two rotating sleeves 531 can drive the two ends of the steel structure to rotate through the clamping hydraulic component 532 and the clamp 533. Combined with the horizontal drive of the moving mechanism to the machine base 1 510 and machine base 2 520, the steel structure can rotate and move simultaneously, thereby realizing the irregular welding of the steel structure by the welding torch 700, meeting the diverse welding needs of the steel structure, and improving the welding efficiency and welding quality of the welding device.

[0046] The working principle of this invention is: Initially, the multiple clamps 533 are all equidistant from the axis of the rotating sleeve 531. Multiple clamping hydraulic components 532, through synchronous extension and retraction, can drive the multiple clamps 533 to move synchronously towards the steel structure, thus achieving centering and clamping of the steel structure. Alternatively, the multiple clamping hydraulic components 532, through individual extension and retraction, can drive the multiple clamps 533 to move intermittently towards the steel structure, achieving stable clamping of irregularly shaped steel structures. By controlling the multiple clamping hydraulic components 532, the clamps 533 can stably clamp steel structures of different specifications, meeting the fixing requirements of the steel structure. When the welding torch 700 needs to perform irregular welding on the steel structure, the rotating assembly 550... The arc-shaped rack 534 drives the rotating sleeve 531 located at one end of the device base 200 to rotate. The arc-shaped rack 534 drives the linkage gear 535 to rotate. The linkage gear 535 drives the linkage gear 535 located at the other end of the device base 200 to rotate through the linkage component. This allows the rotating sleeves 531 located at both ends of the device base 200 to rotate. The two rotating sleeves 531 can drive the two ends of the steel structure to rotate through the clamping hydraulic component 532 and the clamp 533. Combined with the horizontal drive of the moving mechanism to the machine base 1 510 and machine base 2 520, the steel structure can rotate and move simultaneously, thereby realizing the welding torch 700 to weld the irregular shape of the steel structure and meeting the diverse welding needs of the steel structure. Initially, the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 are in a V-shaped open position, which facilitates the smooth entry of the steel structure between them and provides ample control space for the placement of the steel structure. Simultaneously, the slag removal assembly 460 is located on one side of the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430. When the steel structure is positioned between the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430, the first motor 451 simultaneously drives the main gear 452 and the transmission component 453 to rotate. The main gear 452 drives the second control gear 455 to rotate, which in turn drives the first control gear 454 and the second arc-shaped cover plate 430 to rotate. The control gear drives the first arc-shaped cover plate 420 to rotate, causing the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 to rotate towards each other and achieve interference-free closure. The transmission component 453, through rotation and cooperation with the fixed base 410, can... The rotating shaft 468 rotates, which in turn rotates the rotating roller 466 and the spiral guide groove 467 thereon. The spiral guide groove 467, through rotation and in cooperation with the sliding column 465, can drive the upper slider 463 and the lower slider 464 to move horizontally. The upper slider 463 and the lower slider 464 can drive the slag removal seat 461 to move horizontally on the fixed seat 410, thereby restoring the seal on the bottom of both the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430. This not only effectively prevents welding slag from seeping into the gaps at the bottom of both, extending the service life of the first arc-shaped cover plate 420 and the arc-shaped cover plate, but also makes it convenient for workers to clean the welding slag on the slag removal seat 461, preventing welding slag from falling between the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430, ensuring that the first arc-shaped cover plate 420 and the second arc-shaped cover plate 430 can work normally without being affected by welding slag. Meanwhile, the arc-shaped cover plate 420 and the arc-shaped cover plate 430 can also temporarily intercept the gas generated during welding by the welding torch 700, causing it to remain inside the arc-shaped cover plate 420 and the arc-shaped cover plate 430 for a period of time. The suction pump can draw the gas that is temporarily trapped inside the arc-shaped cover plate 420 and the arc-shaped cover plate 430 by suction, so that the gas passes through the branch pipe 441, the main pipe 442 and the connecting hose 443 in sequence and enters the suction pump. The suction pump guides the gas into the gas filter, so that the gas filter can complete the gas treatment, thereby enabling the degassing component 440 to effectively and quickly absorb and purify the gas, optimizing the welding environment. After the steel structure welding is completed, motor 451 reverses its operation and simultaneously drives arc-shaped cover plate 420, arc-shaped cover plate 430, and slag removal component 460 to reverse their operation. This causes arc-shaped cover plate 420 and arc-shaped cover plate 430 to rotate in opposite directions and return to their V-shaped open position, allowing the steel structure inside them to be fully exposed. At this time, slag removal component 460 moves away from arc-shaped cover plate 420 and arc-shaped cover plate 430, thereby releasing the seal on the bottom gap of arc-shaped cover plate 420 and arc-shaped cover plate 430. This not only facilitates the quick cleaning of the welding slag collected by slag removal component 460, but also prevents welding slag from falling between arc-shaped cover plate 420 and arc-shaped cover plate 430 during the cleaning process. Furthermore, it allows for quick and effective cleaning of the bottom gap of arc-shaped cover plate 420 and arc-shaped cover plate 430. The above describes the working principle of the welding device used for steel structure processing.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
