[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1-5 The present invention provides the following technical solution:
[0028] A welding auxiliary fixture for steel structures in building construction with anti-rust function includes a base plate 1 and two steel structure bodies 4. A rotating plate 2 is provided on the top of the base plate 1. A scale mark 3 is provided on the top of the rotating plate 2. A first fixing plate 8 and a second fixing plate 15 are respectively provided on the top of the rotating plate 2. A sliding mechanism 5 is provided at the bottom of the second fixing plate 15. A clamping mechanism 9 is provided on the surface of both the first fixing plate 8 and the second fixing plate 15. A hinge 11 is provided on the top of the rotating plate 2.
[0029] The sliding mechanism 5 includes a limiting plate 501, a sliding column 502, a slider 503, and a limiting rod 504. The bottom of the limiting rod 504 passes through the second fixed plate 15 and is in close contact with the top of the rotating plate 2. The surface of the limiting rod 504 is threadedly connected to the inside of the second fixed plate 15. The top of the limiting plate 501 is fixedly connected to the bottom of the sliding column 502. The top of the sliding column 502 is fixedly connected to the bottom of the slider 503. The top of the slider 503 is fixedly connected to the bottom of the second fixed plate 15.
[0030] In this embodiment: the bottom support column 12 of the rotating plate 2 slides on the annular groove 16 of the base plate 1. Turning the crank 10 allows the rotating plate 2 to be rotated horizontally, adjusting the working position to facilitate subsequent welding of the steel structure body 4. The angle of the second fixed plate 15 is flexibly adjustable. Its bottom slider 503 slides synchronously in the sliding groove 14 of the rotating plate 2 and the sliding column 502 slides synchronously in the through groove 13. With the rotation of the hinge 11, it can rotate around the hinge 11 as an axis. Construction personnel can observe the scale markings 3 to intuitively and quickly determine the rotation angle of the second fixed plate 15. After adjusting to the required angle, the limiting rod 504 is tightened. The limiting plate 501 contacts the rotating plate 2 to increase friction and limit and fix the second fixed plate 15 to prevent angle deviation during welding. Then, the steel structure body 4 is placed on the first fixed plate 8 and the second fixed plate 15. At the second fixed plate 15, rotate the rotating rod 902. Because the rotating rod 902 is threadedly connected to the fixed frame 901, the rotating rod 902 drives the clamping plate 904 and the anti-slip cone 903 to press the steel structure body 4. The anti-slip cone 903 increases the friction and stabilizes the clamping. During welding, the smoke pipe 6 is connected to external equipment, and the smoke hood 7 collects smoke and discharges it through the smoke pipe 6 to improve the environment. The anti-slip support plate 17 of the base plate 1 increases the friction with the ground and ensures stability. After welding is completed, loosen the rotating rod 902, and the anti-slip cone 903 disengages from the steel structure body 4. Take out the welded steel structure body 4. This solves the problem in the existing patent that after the clamp is adjusted, it is not convenient to intuitively judge the angle value. It is necessary to use tools to measure, which affects the efficiency of welding steel structures at specific angles.
[0031] Specifically, such as Figure 1 and Figure 4As shown, the clamping mechanism 9 includes a fixed frame 901, a rotating rod 902, several anti-slip cones 903, and a clamping plate 904. The right side of the left fixed frame 901 is fixedly connected to the surface of the first fixed plate 8, and the rear side of the front fixed frame 901 is fixedly connected to the front side of the second fixed plate 15. The rotating rod 902 is threadedly connected to the inside of the fixed frame 901. The side of the rotating rod 902 near the clamping plate 904 is rotatably connected to the clamping plate 904. The side of the anti-slip cone 903 near the clamping plate 904 is fixedly connected to the clamping plate 904. The surface of the anti-slip cone 903 is in close contact with the surface of the steel structure body 4.
[0032] Specifically, such as Figure 3 and Figure 5 As shown, the rotating plate 2 has a groove 14 inside, the slider 503 is slidably connected inside the groove 14, the bottom of the second fixing plate 15 is in contact with the top of the rotating plate 2, the bottom of the first fixing plate 8 is fixedly connected to the top of the rotating plate 2, and the connection between the first fixing plate 8 and the second fixing plate 15 is rotatably connected by a hinge 11.
[0033] Specifically, such as Figure 3 and Figure 5 As shown, a through groove 13 is provided at the bottom of the inner wall of the slide groove 14, and the slide column 502 is slidably connected inside the through groove 13. The top of the limiting plate 501 is in close contact with the bottom of the rotating plate 2.
[0034] In this embodiment: by moving the two steel structure bodies 4 to contact the surfaces of the first fixed plate 8 and the second fixed plate 15 respectively, and then rotating the rotating rod 902, the clamping plate 904 moves, causing the anti-slip cone 903 to move, so that the surface of the anti-slip cone 903 is in close contact with the surface of the steel structure body 4, the steel structure body 4 can be stably clamped to the angle formed by the first fixed plate 8 and the second fixed plate 15, which facilitates subsequent welding. By sliding the slider 503 inside the sliding groove 14 and the sliding column 502 inside the through groove 13, the rotation of the second fixed plate 15 can be made smoother and more stable, which facilitates the adjustment of the angle of the second fixed plate 15. After the adjustment is completed, the limiting rod 504 is locked, so that the bottom of the limiting rod 504 is in close contact with the top of the rotating plate 2. At this time, the top of the limiting plate 501 will be in close contact with the top of the rotating plate 2, increasing the friction, which can limit and fix the second fixed plate 15, preventing its angle from shifting during the welding process.
[0035] Specifically, such as Figure 2 and Figure 5 As shown, the top of the base plate 1 is provided with an annular groove 16, and the bottom of the rotating plate 2 is fixedly connected with a support column 12. The number of support columns 12 is several and they are evenly distributed on the bottom of the rotating plate 2. The support columns 12 are slidably connected inside the annular groove 16.
[0036] Specifically, such as Figure 1As shown, a crank handle 10 is rotatably connected to the top of the rotating plate 2.
[0037] In this embodiment: the support column 12 is slidably connected inside the annular groove 16, and then the crank handle 10 is turned by hand, which makes it easy to rotate the rotating plate 2 and adjust the welding position.
[0038] Specifically, such as Figure 1 As shown, a smoke hood 7 is fixedly connected to the top of the first fixed plate 8, and a smoke pipe 6 is fixedly connected to the top of the smoke hood 7.
[0039] Specifically, such as Figure 1 As shown, the bottom of the base plate 1 is fixedly connected with anti-slip support plates 17, and there are several anti-slip support plates 17 evenly distributed on the bottom of the base plate 1.
[0040] In this embodiment: during the welding process of the steel structure body 4, by connecting the fumigation pipe 6 to an external fumigation device, the welding smoke generated rises and is collected by the fumigation hood 7, and is sucked into the external fumigation device through the fumigation pipe 6, thus timely expelling the welding smoke, improving the construction environment, and reducing the harm of smoke to construction personnel. By placing the base plate 1 on a stable ground, the anti-slip support plates 17 evenly distributed at the bottom of the base plate 1 increase the friction with the ground, making it convenient to provide stable support for the base plate 1.
[0041] Working principle: The support column 12 at the bottom of the rotating plate 2 slides within the annular groove 16 of the base plate 1. Turning the crank handle 10 can rotate the rotating plate 2 horizontally, facilitating overall adjustment of the working position. The angle adjustment of the second fixed plate 15 is more flexible. Its bottom slider 503 slides within the sliding groove 14 of the rotating plate 2, and the sliding column 502 slides synchronously within the through groove 13. Combined with the hinge 11 connecting the first fixed plate 8 and the second fixed plate 15, the second fixed plate 15 can rotate around the hinge 11 as an axis. During rotation, the construction personnel can visually and quickly determine the rotation of the second fixed plate 15 by observing the evenly distributed scale marks 3 on the top of the rotating plate 2. The angle is adjusted so that the second fixing plate 15 can be adjusted to any required angle to adapt to the welding angle requirements of different steel structures. After the second rotating plate 2 is rotated to the appropriate angle, the limiting rod 504 is tightened so that its bottom is in close contact with the rotating plate 2. At this time, the top of the limiting plate 501 will be in close contact with the top of the rotating plate 2, increasing the friction and thus limiting and fixing the second fixing plate 15 to prevent its angle from shifting during welding. Then, the two steel structure bodies 4 to be welded are placed on the left side of the first fixing plate 8 and the front side of the second fixing plate 15, respectively. Then, the rotating rod 902 inside the fixing frame 901 is rotated. Since the rotating rod 902 and the fixing frame 901 are in close contact, the second fixing plate 15 is fixed. With the threaded connection, the rotating rod 902 moves closer to the steel structure body 4, causing the clamping plate 904 and the anti-slip cone 903 fixed on the clamping plate 904 to move closer to and press against the steel structure body 4. The anti-slip cone 903 increases the friction between the anti-slip cone 903 and the surface of the steel structure body 4, achieving a stable clamping and ensuring that the steel structure body 4 will not shift during welding. During the welding process, by connecting the fume extraction pipe 6 to an external fume extraction device, the welding fumes rise and are collected by the fume extraction hood 7, and then sucked into the external fume extraction device through the fume extraction pipe 6, thus timely removing the welding fumes, improving the construction environment, and reducing the harm of fumes to construction personnel. In addition, the anti-slip support plates 1 are evenly distributed at the bottom of the base plate 1. 7. Increase the friction with the ground to facilitate stable support of the base plate 1. After welding, loosen the rotating rod 902 so that the anti-slip cone 903 is out of contact with the surface of the steel structure body 4, and the welded steel structure body 4 can be moved upward and removed. This solves the problem in the existing patent that after the clamp is adjusted, it is not convenient to intuitively judge the angle value, and tools are needed for measurement, which affects the efficiency of welding steel structures at specific angles. It should be noted that the first fixing plate 8, the second fixing plate 15, the fixing frame 901, the rotating rod 902, the clamp 904 and the anti-slip cone 903 are all made of stainless steel to avoid rust and extend service life.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
