Description

Technical Field

[0001] This utility model relates to the technical field of steel structure welding devices for construction sites, and in particular to a steel structure welding device for construction projects. Background Technology

[0002] In the contemporary construction industry, steel structures, with their superior characteristics, have become a key support for large-scale construction projects. They are high-strength, capable of bearing enormous loads; lightweight, effectively reducing the overall weight of buildings, making them particularly suitable for iconic structures such as high-rise office buildings, large stadiums, and bridges spanning rivers and seas. With the rapid pace of global urbanization and the continuous expansion of cities, the demand for large, multi-functional buildings is exploding. This places stringent requirements on welding, the core connection technology of steel structures. Efficient and high-quality welding technology has become the cornerstone of ensuring the quality and safety of steel structure buildings. Construction sites are notoriously challenging, filled with dust, deafening noise, and constantly exposed to natural elements like wind and rain. In such environments, welding equipment must not only maintain stable operation but also possess robust protective capabilities, resisting interference from dust and rain to ensure the welding process is unaffected by external factors and consistently outputs high-quality welds. Facing steel structure welding tasks of varying shapes and locations, traditional equipment demands extremely high skill levels and experience from operators. Only experienced and highly skilled welders can complete high-quality welding under complex conditions.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: the operation of installing the air inlet pipe is complicated, which leads to a lot of time being spent assembling the fixed pipe and the air inlet pipe; difficult-to-assemble pipes will increase the installation time; some welding gases are toxic, and leakage may cause personnel poisoning; workers need to spend more time and energy to adjust and connect the pipes, resulting in low overall work efficiency and affecting the normal progress of welding work; therefore, in order to address the above problems, a steel structure welding device for construction sites is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the complexity of installation of the air intake pipe, the time-consuming assembly of the fixed pipe and the air intake pipe, the increased installation time for difficult-to-assemble pipes, the toxicity of some welding gases which could cause poisoning if leaked, and the need for workers to spend more time and effort adjusting and connecting pipes, resulting in low overall work efficiency and affecting the normal progress of welding work. Therefore, this invention proposes a welding device for steel structures on construction sites in building engineering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a welding device for steel structures on construction sites for building engineering, comprising a welding torch, a metal tube mounted on the surface of the welding torch, an installation device provided on the arc surface of the metal tube, the installation device comprising a fixing tube, the fixing tube being fixedly connected to the arc surface of the metal tube, two installation grooves being provided on the arc surface of the fixing tube, a first spring being fixedly connected to the inner surface of the installation groove, a blocking block being fixedly connected to the other end of the first spring, an air inlet pipe being slidably connected to the arc surface of the fixing tube, two threaded rods being threadedly inserted into the arc surface of the air inlet pipe, and two circular grooves being provided on the arc surface of the fixing tube.

[0006] The aforementioned components achieve the following effects: by setting up the installation device, it facilitates the installation of the fixed pipe and the air inlet pipe by the workers, avoiding the complicated operation of the air inlet pipe installation, which leads to the fixed pipe and the air inlet pipe requiring a lot of time to assemble. Difficult-to-assemble pipes will increase the installation time. Some welding gases are toxic and may cause personnel poisoning if leaked. Workers need to spend more time and energy to adjust and connect the pipes, resulting in low overall work efficiency and affecting the normal progress of the welding work.

[0007] Preferably, one end of the fixing tube is slidably connected to a leak-proof pad, the size of which is adapted to the size of the fixing tube.

[0008] The effect achieved by the above components is to enhance the sealing between the fixed pipe and the inlet pipe in the gas delivery pipeline system, thereby preventing gas leakage.

[0009] Preferably, a round rod is slidably connected to the inner surface of the circular groove, a movable frame is slidably connected to the arc surfaces of the two round rods, a handle is fixedly connected to the arc surfaces of the round rods, and a second spring is fixedly connected to one end of the two round rods that is close to each other.

[0010] The effect achieved by the above components is to limit the leak-proof pad and prevent the installed leak-proof pad from falling off.

[0011] Preferably, a baffle is fixedly connected to the arc surface of the threaded rod, and one side of the baffle abuts against the fixed tube.

[0012] The effect achieved by the above components is as follows: by setting up a baffle, when one side of the baffle abuts against the arc surface of the fixed tube, the top of the baffle is exactly flush with one side of the arc surface of the fixed tube, which makes it easier for the staff to disassemble the air intake pipe and prevents the threaded rod from rotating too much and inserting into the installation groove, which is not conducive to the operation of the staff.

[0013] Preferably, the arc surface of the metal tube is provided with a clamping device, the clamping device including a sliding tube, the sliding tube being slidably connected to the arc surface of the metal tube, a nut being threaded into the arc surface of the sliding tube, an arc plate being fixedly connected to the inner surface of the sliding tube, a screw being threaded into the arc surface of the sliding tube, a semi-circular plate being rotatably connected to one end of the screw, and a welding rod being slidably connected to the inner surface of the arc plate.

[0014] The effect achieved by the above-mentioned components is as follows: by setting up a clamping device, the welding rod is clamped, which avoids the welding rod shaking when the worker is welding metal. During the welding process, the shaking of the welding rod will cause the arc to be unstable, resulting in inconsistent weld width, uneven surface, wavy or unevenness, which affects the aesthetics of the weld. The shaking causes the base metal to be melted and form a depression. The increased contact area enhances the clamping of the welding rod in multiple directions and angles, thereby increasing the clamping stability.

[0015] Preferably, a guide rod is slidably inserted into the arc surface of the sliding tube, and the guide rod is fixedly connected to the arc surface of the semicircular plate.

[0016] The effect achieved by the above components is that the screw rotates inside the sliding tube, and the semicircular plate drives the guide rod to slide inside the sliding tube, thus preventing the semicircular plate from rotating with the screw.

[0017] Preferably, the arc surface of the semicircular plate is fixedly connected to an anti-slip plate, and the surface of the anti-slip plate has several protrusions.

[0018] The effect achieved by the above-mentioned components is to enhance the friction between the semicircular plate and the welding rod by designing an anti-slip plate, thereby preventing the welding rod from slipping.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, by setting up an installation device, the installation of the fixed pipe and the air inlet pipe can be made easier for workers. This avoids the complicated operation of installing the air inlet pipe, which would otherwise require a lot of time to assemble the fixed pipe and the air inlet pipe. Difficult-to-assemble pipes would increase the installation time. Some welding gases are toxic and may cause poisoning if leaked. Workers would need to spend more time and energy to adjust and connect the pipes, resulting in low overall work efficiency and affecting the normal progress of the welding work.

[0021] 2. In this utility model, by setting a clamping device, the welding rod is clamped, which avoids the welding rod shaking when the worker is welding metal. During the welding process, the shaking of the welding rod will make the arc unstable, resulting in inconsistent weld width, uneven surface, wavy or unevenness, which affects the aesthetics of the weld. The shaking will cause the base metal to melt and form a depression. The increased contact area enhances the clamping of the welding rod in multiple directions and angles, thereby increasing the clamping stability. Attached Figure Description

[0027] Reference Figure 1As shown, this utility model provides a technical solution: a steel structure welding device for construction sites, including a welding torch 1, a metal pipe 2 mounted on the surface of the welding torch 1, and an installation device 4 provided on the arc surface of the metal pipe 2. By setting the installation device 4, it is possible for workers to easily install the fixed pipe 401 and the air inlet pipe 406, avoiding the complicated operation of workers installing the air inlet pipe 406, which would otherwise require a lot of time to assemble the fixed pipe 401 and the air inlet pipe 406. Difficult-to-assemble pipes would increase the installation time. Some welding gases are toxic and may cause poisoning if leaked. Workers would need to spend more time and energy adjusting and connecting pipes, resulting in low overall work efficiency and affecting the normal progress of welding work. The arc surface of the metal tube 2 is equipped with a clamping device 5. By setting the clamping device 5, the welding rod 3 is clamped, which avoids the welding rod 3 shaking when the worker is welding metal. During the welding process, the shaking of the welding rod 3 will cause the arc to be unstable, resulting in inconsistent weld width, uneven surface, wavy or uneven appearance, which affects the aesthetics of the weld. The shaking will cause the base metal to be melted and form a depression. The increased contact area enhances the clamping of the welding rod 3 in multiple directions and angles, thereby increasing the clamping stability.

[0028] The specific setup and function of the mounting device 4 and the clamping device 5 will be explained in detail below.

[0029] Reference Figure 2 and Figure 3As shown in this embodiment: the installation device 4 includes a fixing pipe 401, which is fixedly connected to the arc surface of the metal pipe 2. Two mounting grooves 402 are formed on the arc surface of the fixing pipe 401. A first spring 403 is fixedly connected to the inner surface of the mounting grooves 402. A blocking block 404 is fixedly connected to the other end of the first spring 403. An air inlet pipe 406 is slidably connected to the arc surface of the fixing pipe 401. Two threaded rods 405 are threadedly inserted into the arc surface of the air inlet pipe 406. Two circular grooves 407 are formed on the arc surface of the fixing pipe 401. A leak-proof gasket 408 is slidably connected to one end of the fixing pipe 401, and the size of the leak-proof gasket 408 is adapted to the size of the fixing pipe 401. In the gas conveying pipeline system, this enhances the sealing between the fixing pipe 401 and the air inlet pipe 406 to prevent gas leakage. A circular rod 409 is slidably connected to the inner surface of the circular groove 407. A movable frame 410 is slidably connected to the arc surfaces of two circular rods 409. A handle 411 is fixedly connected to the arc surfaces of the circular rods 409. A second spring 412 is fixedly connected to the ends of the two circular rods 409 that are close to each other. This limits the anti-leakage pad 408 to prevent it from falling off after installation. A baffle 413 is fixedly connected to the arc surface of the threaded rod 405. One side of the baffle 413 abuts against the fixed tube 401. By setting the baffle 413, when one side of the baffle 413 abuts against the arc surface of the fixed tube 401, the top of the baffle 413 is exactly flush with one side of the arc surface of the fixed tube 401, which makes it easier for the operator to disassemble the air intake pipe 406 and prevents the threaded rod 405 from rotating too much and inserting into the installation groove 402, which would be detrimental to the operator's operation.

[0030] Reference Figure 4 As shown, specifically, the clamping device 5 includes a sliding tube 51, which is slidably connected to the arc surface of the metal tube 2. A nut 52 is threaded into the arc surface of the sliding tube 51. An arc plate 53 is fixedly connected to the inner surface of the sliding tube 51. A screw 55 is threaded into the arc surface of the sliding tube 51. A semi-circular plate 54 is rotatably connected to one end of the screw 55. A welding rod 3 is slidably connected to the inner surface of the arc plate 53. A guide rod 56 is slidably inserted into the arc surface of the sliding tube 51 and is fixedly connected to the arc surface of the semi-circular plate 54. The screw 55 rotates inside the sliding tube 51, and the semi-circular plate 54 drives the guide rod 56 to slide inside the sliding tube 51, preventing the semi-circular plate 54 from rotating with the screw 55. An anti-slip plate 57 is fixedly connected to the arc surface of the semi-circular plate 54, and several protrusions are reserved on the surface of the anti-slip plate 57. By designing the anti-slip plate 57, the friction between the semi-circular plate 54 and the welding rod 3 is enhanced, preventing the welding rod 3 from slipping.

[0031] Working principle: When workers need to weld metal using the steel structure welding device, first install the fixing pipe 401 and the air inlet pipe 406 of the installation device 4. Place the leak-proof pad 408 on one side of the fixing pipe 401, ensuring a tight connection between the leak-proof pad 408 and one side of the fixing pipe 401. Then, press the handle 411 to compress the second spring 412, which slides on the inner surface of the movable frame 410. Next, place the movable frame 410 between the two circular grooves 407. Release the handle 411 and the second spring 412. Under the elastic force of the second spring 412, the circular rod 409 springs to the inner surface of the circular groove 407, thereby limiting the leak-proof pad 408. Then, rotate the threaded rod 405 within the threaded hole of the air inlet pipe 406 until the baffle 413 is close to the air inlet pipe. After a distance of 406, slide the inner surface of the intake pipe 406 forward along the arc surface of the fixed pipe 401 to press the blocking block 404, thereby compressing the first spring 403 in the mounting groove 402. When the blocking block 404 springs into the mounting groove 402 of the intake pipe 406, it limits the intake pipe 406 and the fixed pipe 401. When it is necessary to remove the intake pipe 406, rotate the threaded rod 405 in the threaded hole of the intake pipe 406 until the arc surface of the intake pipe 406 on one side of the baffle 413 abuts. When the first spring 403 is compressed in the mounting groove 402, the blocking block 404 springs into the mounting groove 402 of the intake pipe 406, and then limits the intake pipe 406 and the fixed pipe 401 again, so that the intake pipe 406 can be removed.

[0032] When the operator needs to use the clamping device 5 to clamp the welding rod 3, first slide the sliding tube 51 along the arc surface of the metal tube 2. When it slides to the designated position, rotate the nut 52 to abut against the metal tube 2. When the nut 52 abuts tightly against the metal tube 2, slide the welding rod 3 between the arc plate 53 and the anti-slip plate 57. Rotate the screw 55 to rotate inside the sliding tube 51, driving the semi-circular plate 54 to move forward. Under the guidance of the guide rod 56, drive the semi-circular plate 54 to move. When the anti-slip plate 57 tightly presses against the welding rod 3, the welding rod 3 can be used.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
